Retained foreign bodies following penetrating brain injuries continue to pose therapeutic dilemmas. Previously used aggressive approach involving extensive wound debridement and removal of foreign bodies caused additional neurological deficit with higher mortality. Less aggressive approach used more recently involving decompressive craniectomy has lead to higher incidence of retained foreign bodies with potential of infective sequelae. We describe one such case where, in presence of a retained foreign body, an intracranial abscess formed after a gap of 17 yrs. The case has peculiar radiological and morphological findings.

Peripheral nonlactational abscesses behave like other soft tissue abscesses and resolve with drainage and antibiotics. Subareolar abscesses tend to recur or develop fistulae between obstructed ducts and the border of the areola and are usually seen in women in their thirties who have a history of smoking or a congenitally cleft nipple. The underlying cause of subareolar abscesses and fistulae is the obstruction of terminal ducts due to keratin plugging caused by squamous metaplasia of the ducts. Successful resolution of the problem requires excision of the terminal ducts in and just below the nipple along with the correction of nipple deformity, if present.

Treatment of breast abscesses is based on drainage and antibiotic therapy directed at the bacteria causing the infection. The aim of this study was to know the etiological agents of breast abscesses.Patients who had a culture-positive breast abscess between September 2015 and January 2020 were included in the study. Culture results were consulted in the laboratory database. It was collected from medical records if the patients presented the following risk factors: breastfeeding, diabetes or smoking. Abscesses secondary to surgical wound infection were excluded.Sixty patients were included, 58 women and 2 men. Staphylococcus aureus was the most frequent agent in lactating women. Anaerobic bacteria were isolated in 28 (61%) of 46 abscesses in non-lactating patients. In non-lactating patients, the frequency of anaerobes in abscesses was lower in diabetics than in the rest (0/5 vs 26/38; P = .013). In non-lactating and non-diabetic patients, the proportion of abscesses with anaerobes was higher in smokers than in non-smokers (21/24 vs 5/14; P = .003). Aerobic gram-positive cocci were the most frequent agents in diabetics.Anaerobes were the most frequent agents, followed by S. aureus. The etiology of breast abscesses varied with the risk factors studied.

Antimicrobial peptides (AMPs) have started to garner more interest as novel antimicrobial agents. The scorpion venom peptide ctry2459 was modified to CT-K3K7 by lysine substitutions at the 3rd and 7th positions to increase the cationic properties. We discovered that the modified peptides CT-K3K7 had improved antibacterial activity, higher thermal stability, as well as lower hemolytic activity. It can kill S. aureus and P. aeruginosa rapidly, and reduce the production of biofilm and live bacterial residues in biofilm in vitro. CT-K3K7 has also been demonstrated to decrease bacterial counts, abscess area, and inflammatory cell infiltration in the mouse subcutaneous abscess models that were duplicated by S. aureus and P. aeruginosa. CT-K3K7 has difficulty in inducing S. aureus and P. aeruginosa to develop drug resistance, which may be related to the bactericidal properties. CT-K3K7 increases cationic properties by lysine substitutions can increase the electrostatic force between the peptides and the bacterial surface, which can lead to an increase in bacterial membrane permeability and DNA binding. In conclusion, the modified peptide CT-K3K7 enhances the antimicrobial activity and can be a novel antimicrobial agent candidate for the treatment of infections by S. aureus and P. aeruginosa.

Crohn disease (CD) patients can develop fistula or abscess from persistent active disease or postsurgical complications. Penetrating CD is traditionally treated with medication and surgery. The role of medication alone in the treatment of fistula is limited, except perianal fistulas or enterocutaneous fistula. Surgery is the standard treatment in those with hollow-organ to hollow-organ fistula, like ileovesicular fistula. Surgery is invasive with a higher risk of postoperative complications. Endoscopic therapy has evolved as a valid option. Fistulotomy, surgical or endoscopic, should be considered first-line therapy when feasible. Incision and drainage of perianal abscesses with an endoscopic device may be attempted.

Background Regional anesthesia has been increasingly used. Despite its low number of complications, they are associated with relevant morbidity. This study aims to evaluate the incidence of complications after neuraxial block and peripheral nerve block. Methods A retrospective cohort study was conducted, and data related to patients submitted to neuraxial block and peripheral nerve block at a tertiary university hospital from January 1, 2011 to December 31, 2017 were analyzed. Results From 10,838 patients referred to Acute Pain Unit, 1093(10.1%) had side effects or complications: 1039 (11.4%) submitted to neuraxial block and 54 (5.2%) to peripheral nerve block. The most common side effects after neuraxial block were sensory (48.5%) or motor deficits (11.8%), nausea or vomiting (17.5%) and pruritus (8.0%); The most common complications: 3 (0.03%) subcutaneous cell tissue hematoma, 3 (0.03%) epidural abscesses and 1 (0.01%) arachnoiditis. 204 of these patients presented sensory or motor deficits at hospital discharge and needed follow-up. Permanent peripheral nerve injury after neuraxial block had an incidence of 7.7:10,000 (0.08%). The most common side effects after peripheral nerve block were sensory deficits (52%) and 21 patients maintained follow-up due to symptoms persistence after hospital discharge. Conclusion Although we found similar incidences of side effects or even lower than those described, major complications after neuraxial block had a higher incidence, particularly epidural abscesses. Despite this, other serious complications, such as spinal hematoma and permanent peripheral nerve injury, are still rare.

There are few reports of multilocus sequence type (ST) 5/staphylococcal cassette chromosome (SCC) mec type IVc/toxic shock syndrome toxin (TSST)-1- positive methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infections. We report a case of community-onset MRSA (CO-MRSA) bloodstream infection in a healthy 41-year-old Japanese man after nasal septoplasty, followed by pectoral abscess and costal osteomyelitis. The patient presented with right anterior chest pain and fever. After admission, MRSA was isolated from two sets of blood cultures, and vancomycin was administered. On the fifth day, contrast-enhanced computed tomography (CT) scan and contrast-enhanced magnetic resonance imaging (MRI) scan showed an abscess in the right anterior chest to the right subpleural region. The dosage of vancomycin (4 g/day) did not reach the effective blood concentration; therefore, there was a switch to daptomycin. On the 23rd day, contrast-enhanced MRI revealed osteomyelitis of the right first rib, and as a result, linezolid was initiated. Two weeks later, contrast-enhanced CT of the chest showed improvement in the abscess. The patient was treated for 6 weeks during hospitalization and then switched to minocycline for 10 weeks. Molecular characterization of this isolate showed that it was ST5/SCCmec type IVc/TSST-1-positive/Panton-Valentine leucocidin (PVL)-negative. PVL-negative CO-MRSA can lead to hematogenous osteomyelitis and abscess even if the patient is immunocompetent, and if isolated from blood cultures, it is important to repeat imaging studies, even if the initial imaging studies were normal. It is possible that this strain contributes to the pathogenesis of invasive CO-MRSA, but further case accumulation is needed.

Malakoplakia is a rare pseudotumor that arises in the context of recurrent infections, particularly in immunocompromised states. We report a case of renal allograft parenchymal malakoplakia.A 59-year-old woman successfully received a cadaveric renal transplant in June 2018. Two months after transplantation, she was treated for a urinary tract infection (UTI). In March 2019, she underwent allograft biopsy for increasing creatinine. The biopsy identified T cell mediated rejection and steroid pulse therapy was performed. In December 2019, she was hospitalized for right flank pain and pyuria, and her creatinine level was 1.9 mg/dL. Radiographic findings were suggestive of a hematoma or abscess in the perirenal area, and septated fluid collection was suspected. Biopsy results suggested malakoplakia, and von Kossa stain was positive for Michaelis- Gutmann bodies. Tissue culture demonstrated Escherichia coli, and this was treated with antibiotics. The dose of tacrolimus was reduced. The patient was discharged after 1 month of hospitalization and was maintained on oral antibiotics. Follow-up imaging revealed an increase in the extent of lesion into the adjacent abdominal wall. Assuming the case to be refractory, we performed surgical resection and abscess drainage. Although the renal parenchymal involvement persisted, the size showed a decreasing trend over 2 months of serial observation with ultrasonography.Malakoplakia should be considered as a differential diagnosis for recurrent UTI with graft dysfunction. Malakoplakia can be successfully treated with reduction in immunosuppression and medical therapy using long-term antibiotic treatment in most cases. However, early surgical treatment must be considered for refractory cases.

Introduction Deep neck infections are a group of diseases with serious complications and mortality, which can occur as a result of common diseases in the community and which have surgical and medical treatment options. Objectives Patients ages, genders, complaints, physical examination findings, hospitalization complaints, history of antibiotic use before the application, additional diseases, radiological tests and analysis of examinations, type of treatment method, antibiotic agents selected in treatment, bacterial culture results, duration of hospitalization, complications, mortality rates were systematically recorded. In the study, anaerobic bacterial factors, which are difficult to produce in routine, were produced by considering special transport conditions and culture media. Methods A total of 74 patients who were hospitalized in the Department of Otorhinolaryngology, University of Mersin, between 01.07.2016 and 01.07.2017 for deep neck infection were evaluated prospectively. The study included 37 female and 37 male patients. The ages of the patients ranged from 1 to 69 and the mean age was 31 years. Results According to the analysis of the obtained data, there was a statistically significant relationship between the patients with additional diseases and the treatment modalities of the patients (p = 0.017). The surgical treatment rate was increased in this group of patients. In patients with a history of antibiotic use, it was found that patients in the pediatric group were in hospital longer in terms of length of stay compared to adults (p = 0.036). In adult patients who underwent surgery, the absorptive long axis was found to be longer in mm than in patients receiving isolated medical treatment (p = 0.008). Conclusions Deep neck infections is a disease group that seriously concerns public health, with significant mortality and morbidity. Ensuring airway safety of patients should be the first intervention. Abscesses located lateral to the tonsil capsule may not drain adequately without concomitant tonsillectomy.

Tubo-ovarian abscess (TOA) is a rare but serious condition that carries with it a high rate of morbidity and even mortality.This review highlights the pearls and pitfalls of TOA, including diagnosis, initial resuscitation, and management in the emergency department (ED) based on current evidence.TOA is associated with pelvic inflammatory disease (PID) as well as intrauterine devices, uterine procedures, multiple sexual partners, diabetes mellitus, and immunocompromised states. While usually arising from a gynecologic infection, TOA can be associated with a gastrointestinal source. History and physical examination are limited, demonstrating predominantly lower abdominal pain, but a minority of patients will present with vaginal symptoms. Half of patients will exhibit systemic illness to include fever, nausea, and vomiting. Laboratory evaluation may reveal elevations in white blood cell count and other inflammatory markers. Transvaginal ultrasound and computed tomography (CT) may be utilized for diagnosis, though CT has higher sensitivity and can differentiate this disease from similarly presenting gastrointestinal pathology. Initial medical management includes antibiotics. Surgical intervention is indicated in those who fail initial medical therapy, which is more likely in those with bilateral abscesses, large abscesses, and older patients.An understanding of TOA can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

To describe the authors' experience diagnosing and managing intra-abdominal complications following robotic peritoneal flap vaginoplasty. The peritoneal flap vaginoplasty is a technique used to achieve consistent vaginal depth regardless of available natal tissue. Intra-abdominal complications following robotic peritoneal flap creation are rare but prompt diagnosis and management is critical to preventing patient harm. Given the infancy of the technique there is limited data on associated complications and their management.Retrospective chart review identified patients undergoing robotically assisted peritoneal flap vaginoplasty by the senior authors between 2017 and 2020 who subsequently developed intra-abdominal complications requiring readmission and/or return to the operating room. Patient charts were analyzed for preoperative demographics, medical comorbidities, intraoperative details, postoperative complication presentation, diagnosis, management, and long-term outcomes.Out of 274 patients undergoing peritoneal flap vaginoplasty during the study period, six patients were identified who developed intra-abdominal complications (2.2%). One patient developed a postoperative hematoma requiring return to the operating room for diagnostic laparoscopy and hematoma evacuation. Two patients developed intraabdominal abscesses requiring diagnostic laparoscopy and abscess drainage. One patient developed recurrent episodes of small bowel obstructions that resolved with bowel rest. Two patients developed incarcerated internal hernias requiring diagnostic laparoscopy and internal hernia reduction. In one case, the hernia occurred at the peritoneal flap closure site, and in the other case the hernia occurred at the peritoneal flap donor site.Intra-abdominal complications following robot assisted peritoneal flap vaginoplasty are rare. In addition to hematoma and abscess, small bowel incarceration and internal hernias are potential complications of peritoneal flap vaginoplasty that require prompt attention.

Infantile hypertrophic pyloric stenosis is treated by either open pyloromyotomy (OP) or laparoscopic pyloromyotomy (LP). The aim of this meta-analysis was to compare the open versus laparoscopic technique.A literature search was conducted from 1990 to February 2021 using the electronic databases MEDLINE, Embase, and Cochrane Central Register of Controlled Trials. Primary outcomes were mucosal perforation and incomplete pyloromyotomy. Secondary outcomes consisted of length of hospital stay, time to full feeds, operating time, postoperative wound infection/abscess, incisional hernia, hematoma/seroma formation, and death.Seven randomized controlled trials including 720 patients (357 with OP and 363 with LP) were included. Mucosal perforation rate was not different between groups (relative risk [RR] LP versus OP 1.60 [0.49-5.26]). LP was associated with nonsignificant higher risk of incomplete pyloromyotomy (RR 7.37 [0.92-59.11]). There was no difference in neither postoperative wound infections after LP compared with OP (RR 0.59 [0.24-1.45]) nor in postoperative seroma/hematoma formation (RR 3.44 [0.39-30.43]) or occurrence of incisional hernias (RR 1.01 [0.11-9.53]). Length of hospital stay (-3.01 h for LP [-8.39 to 2.37 h]) and time to full feeds (-5.86 h for LP [-15.95 to 4.24 h]) were nonsignificantly shorter after LP. Operation time was almost identical between groups (+0.53 min for LP [-3.53 to 4.59 min]).On a meta-level, there is no precise effect estimate indicating that LP carries a higher risk for mucosal perforation or incomplete pyloromyotomies compared with the open equivalent. Because of very low certainty of evidence, we do not know about the effect of the laparoscopic approach on postoperative wound infections, postoperative hematoma or seroma formation, incisional hernia occurrence, length of postoperative stay, time to full feeds, or operating time.

Mycobacterium tilburgii, a nonculturable mycobacterium, is an important nontuberculous mycobacterium that occasionally causes serious infections in patients with cellular immune deficiencies. Due to its nonculturable nature, information about its drug susceptibility is not available, and data about its clinical response to antimycobacterial treatment remains insufficient. Here, we report a case of a patient who presented with neck swelling and was finally diagnosed with cervical abscess caused by M. tilburgii carrying anti-interferon gamma autoantibodies using a molecular method. The relevant literature was reviewed in the context of epidemiological and clinical data on M. tilburgii infections. In this report, 15 patients were reported to be infected with M. tilburgii. Almost all patients had a cellular immune deficiency and presented with disseminated infections. Multiple refractory or relapse cases that often required prolonged antimycobacterial treatment have been reported, although a few fatal cases have also been reported. In conclusion, M. tilburgii is an important pathogen in patients with cellular immune deficiency. Physicians should thoroughly investigate cellular immune deficiency, including adult-onset immune deficiency with anti-interferon gamma autoantibodies, in patients with M. tilburgii infection.

Each of the 3 morphological subtypes of cholangiocarcinoma has a different set of imaging differentials. Emulators of mass-forming cholangiocarcinoma include other primary and secondary hepatic malignancies, benign tumors and tumor-like mimics such as abscess, hemangioma and confluent hepatic fibrosis. Benign inflammatory biliary strictures constitute the major differential of periductal-infiltrative type and intraductal calculi are the main consideration for intraductal-growth type. CT and MRI are the standard imaging tools for characterization of cholangiocarcinoma and differentiating it from close mimics. Here we will describe the various tumoral and non-tumoral mimics of cholangiocarcinoma and discuss specific imaging features useful in differentiation.

Background Legionella is a well known but infrequent cause of bacterial endocarditis. Methods We report a case of endocarditis caused by Legionella spp. We reviewed previously reported cases in PubMed, Google Scholar and in references included in previous reports, and summarized relevant clinical data. Results A 63-year-old man with a history of aortic valve replacement developed persistent fever and monoarthritis. Transesophageal echocardiography showed perivalvular abscess. He died during surgery. Blood and valve cultures were negative. Legionella spp. was demonstrated with 16S-rRNA PCR from the resected material. Twenty cases of Legionella endocarditis have been reported. Harboring a prosthetic valve was the main risk factor. Prognosis was favorable, both for patients treated with or without surgical valve replacement. Overall mortality was Conclusions Legionella is an infrequent cause of endocarditis. It frequently requires surgical treatment. Prognosis is good. Molecular techniques are likely to become the gold standard for diagnosis.

This case-series aims to report three cases of endogenous endophthalmitis due to invasive Klebsiella pneumoniae syndrome. Case 1 A 34-year-old lady who was admitted for pneumonia developed painful blurring of vision and redness in the right eye (RE) for one week. An examination of the RE revealed visual acuity (VA) of light perception (PL) with positive relative afferent pupillary defect (RAPD), proptosis, and restriction of extraocular movement with hypopyon. The patient was treated for RE panophthalmitis with a lung abscess and was started on systemic and topical antibiotics. The vitreous tap culture grew Klebsiella pneumoniae. Despite treatment, the patient's condition deteriorated, and evisceration was undertaken. Case 2 A 38-year-old lady presented with a sudden painful RE associated with blurred vision and redness for two days, and fever for one week. RE VA was hand movement with a positive RAPD and anterior chamber cells of 2+. A B-scan revealed a dome-shaped subretinal mass with exudative retinal detachment. The patient was treated for RE panophthalmitis complicated by a basal ganglia abscess. The urine and vitreous tap cultures grew Klebsiella pneumoniae. She responded to high-dose intravenous and intravitreal antibiotics. Unfortunately, her RE became phthisical. Case 3 A 70-year-old lady presented with painless blurring of vision over the RE. The blood and urine cultures grew Klebsiella pneumoniae. RE VA was PL, and she was treated for endogenous endophthalmitis. The vitreous culture grew Klebsiella pneumoniae. Unfortunately, the RE became phthisical. In conclusion, endophthalmitis due to Klebsiella pneumoniae is invasive and carries a poor prognosis if prompt treatment is not rendered.

With the increased emergence and threat of multi-drug resistant microorganisms, MXenes have become not only an emerging class of two-dimensional functional nanomaterials, but also potential nanomedicines (i.e., antimicrobial agents) that deserve further exploration. Very recently, Ti

An abscess is a localized collection of purulent material surrounded by inflammation and granulation in response to an infectious source. Most simple abscesses can be diagnosed upon clinical examination and safely be managed in the ambulatory office with incision and drainage. Wound culture and antibiotics do not improve healing, but packing wounds larger than 5 cm may reduce recurrence and complications.

Pituitary abscesses are very uncommon. They are divided into primary, arising within a healthy gland, and secondary, observed with an underlying pre-existing lesion. Here we present the eighth case reported of a secondary abscess within a craniopharyngioma. A 59-year-old-woman presented with a 3-week history of headache, and fever. Physical examination was unremarkable. An Magnetic Resonance Imaging (MRI) showed a pituitary lesion suggestive of a chronic inflammatory process. She was diagnosed with lymphocytic meningitis with hypophysitis and she was treated with corticosteroids. Two months later she presented with headache and fever again. Control MRI showed enlargement of the pituitary lesion. Therefore, a transsphenoidal biopsy was performed. During the procedure, purulent material was released. Histological study demonstrated a craniopharyngioma and meningeal inflammation. Empiric antibiotics were started. Three months post-operatively, a follow-up MRI showed a suspect minimal residual mass. Secondary pituitary abscesses are rare. The key to successful management is a high index of suspicion. Transsphenoidal surgical evacuation plus antibiotics is the mainstay of treatment. Although most symptoms resolve, endocrinopathies improve only rarely.

Incision and drainage (ID) of abscesses is one of the most painful procedures performed in emergency departments (EDs).We tested the following hypothesis: The addition of intranasal fentanyl to the standard practice of local infiltration with lidocaine would provide better pain control than lidocaine alone for adult ED patients undergoing ID.This was a randomized, double-blind study. Participants received 2 μg/kg of intranasal fentanyl or a comparable amount of intranasal water in addition to local lidocaine infiltration. The primary outcome, which we assessed immediately after the ID was completed, was a summary 0-10 pain score for which we asked study subjects to provide a number depicting their entire experience with the procedure.During a 19-month enrollment period, we screened 176 patients for eligibility and enrolled 49; 25 received placebo and 24 received fentanyl. Baseline characteristics were comparable. Mean (standard deviation) summary pain scores were as follows: fentanyl 6.2 (3.3) and placebo 7.0 (3.2). The 95% confidence interval for a rounded between-group difference of 0.9 was -1.1 to 2.6.In this small study, the addition of intranasal fentanyl did not substantially impact the pain scores of ED patients undergoing ID.

BACKGROUND Despite the liver being one of the most frequently injured abdominal organs in trauma patients, clinical management strategies differ between trauma surgeons. Few studies have critically evaluated current practice patterns in the operative management of liver trauma. Historical studies recommended against the use of drains but there has not been a modern investigation of this issue. The objective of this study was to analyze outcomes associated with intra-operative drain use for liver trauma. METHODS A retrospective chart review of all adult trauma patients presenting to a Level I trauma center from 2012 to 2018 was performed. Patients who underwent operative management of liver trauma were divided into groups based on whether an intra-abdominal drain was utilized and differences in outcomes between the groups were analyzed. The primary endpoint evaluated was post-operative intra-abdominal abscesses. Univariate and multivariate analyses were performed. RESULTS 184 patients with operative management of liver trauma were included in the study. Closed suction drains were utilized in 26.1% of post-operative patients. Rate of intra-abdominal abscesses was significantly higher in the drain group (35.4% versus 8.8%, P < 0.001). Drains were more commonly used in patients receiving more units of PRBCs (median, 9 units [IQR 4-20] versus median 5.5 units, [IQR 2-14], P = 0.03). Drain use was found to be an independent risk factor for post-operative intra-abdominal abscess on multivariate analysis (OR 4.9, 95% CI 1.7-14, P = 0.003). CONCLUSIONS The results of this study support previous conclusions that drain placement for operative liver trauma is associated with increased risks of infectious complications. Drains were used in patients with more severe liver injury, intra-operative bile leaks, penetrating trauma, and increased blood transfusion requirements. Future studies should focus on the development of specific guidelines for the use of drains in liver trauma.

Background We describe a minimally invasive, image-guided technique for obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome complicated by tubo-ovarian abscess (TOA). Case A 15-year-old female adolescent with OHVIRA syndrome presented with TOA. Magnetic resonance imaging of the abdomen/pelvis showed a loculated pelvic mass and fluid collection near the obstructed left hemivagina. Tissue quality and ill-defined surgical planes prevented surgical excision. A transabdominal drain was placed via laparoscopic port by Interventional Radiology. She later underwent transvaginal and transabdominal drain placement into the hemivaginal collection using computed tomography and ultrasound guidance, allowing for surgical excision of the vaginal septum, drainage and excision of the TOA, and neosalpingostomy. Summary and Conclusion Because of the anatomic complexity in OHVIRA syndrome, preoperative minimally invasive techniques with Interventional Radiology collaboration can assist intraoperative anatomic navigation for successful surgical treatment.

Cutaneous tuberculosis classically presents as Lupus vulgaris, scrofuloderma, tuberculosis verrucose cutis and tubercular abscess. Hypersensitivity reaction to the bacilli leads to Lichen scrofulosorum and papulonecrotic tuberculids. At the same time, it can have myriad of clinical presentations, many of which are still undescribed. It is important to regularly update ourselves with these unusual manifestations so as to ensure early treatment and reduction of overall morbidity. In this case series tuberculosis manifesting as rapidly progressing diffuse facial granulomas, sporotrichoid tuberculosis, tuberculosis mimicking squamous cell carcinoma, scrofuloderma as tubercular ulcer, lupus vulgaris with nasal septal perforation, lupus vulgaris resembling furuncle, psoriasis, dermatitis and BT Hansen are described in immunocompetent individuals. These cases highlight the importance of recognition of atypical forms of cutaneous tuberculosis to minimize scarring and dissemination of bacilli.

The most common cause of deep neck infections is dental infection. They are diagnosed with physical examination, imaging studies, ultrasound, or computed tomography. Surgical drainage of collections should always be performed early in a classical or percutaneous way, depending on the case. The aim of the study was to compare ultrasound-guided percutaneous drainage techniques vs. surgical drainage in deep cervical abscesses of odontogenic origin in a controlled and randomized trial.A randomized controlled clinical trial was performed from January 2015 to December 2019. Hospital stay was evaluated as an efficiency variable. Epidemiological and secondary variable data (tumour, trismus, fever, pain), leukocytosis, cosmetic result comparing both techniques were analysed. Statistical analysis was carried out with STATA v 14.0.128 patients were analysed, 51 women and 77 men. Average age 27.3 (SD = 10.13). The percutaneous group had a mean hospital stay of 3.03 (SD = 2.86) days and the surgical group 5.46 (SD = 2.96). The p-value was.001. Cosmetic results showed differences favouring the percutaneous drainage group. None of the other variables showed statistically significant results.Surgical treatment (cervicotomy and debridement) should be undertaken early with evidence of extensive collection in deep spaces. Minimally invasive image-guided procedures are an alternative. These can be performed in well-located, unilocular collections, without compromising of the patient's airway. Percutaneous drainage and suction techniques if necessary, serially, or drainage placement may be performed.Ultrasound-guided and serially guided percutaneous drainage is the best therapeutic option in patients with mild and/or moderate dental infections.

Background The UK has one of the highest rates of recreational drug use and consequent deaths in Europe. Scotland is the “Drug deaths capital of Europe.” Intravenous drug use can result in limb- and life-threatening pathology. This study aimed to characterise limb-related admissions associated with intravenous drug use, outcomes and healthcare expenditure. Methods Retrospective data collection between December 2011 and August 2018. Patients were identified through discharge codes. Admission details were extracted from electronic records and a database compiled. Statistical analyses were performed using Statistical Package for the Social Science, P Results There were 558 admissions for 330 patients (1–9 admissions/patient), mean age 37 years (+/-7.6 SD) and 196 (59.2%; 319 admissions, 57.2%) were male. Three hundred forty-eight (62.4%) admissions were to surgical specialties, predominantly Vascular Surgery (247). Including onward referrals, Vascular ultimately managed 54.8% of admissions. Patients presented with multiple pathologies: 249 groin abscesses; 38 other abscesses; 74 pseudoaneurysms; 102 necrotising soft tissue infections (NSTI); 85 cellulitis; 138 deep venous thrombosis (DVTs); 28 infected DVTs and 70 other diagnoses. Two hundred and seventy-seven admissions (220 patients) required operations, with 361 procedures performed (1–7 operations/admission). There were 24 major limb amputations and 74 arterial ligations. Eleven amputations were due to NSTI and 13 followed ligation (17.6% of ligations). During follow-up 50 (15.2%) patients died, of which 6 (12%) had amputations (OR 3.2, 95% CI 1.04–9.61, P = 0.043). Cumulative cost of acute care was £4,783,241. Conclusions Limb-related sequalae of intravenous drug use represents a substantial surgical workload, especially for Vascular. These are complex, high-risk patients with poor outcomes and high healthcare costs.

Hepatic artery pseudo-aneurysm and hepato-fastric fistula are extremely rare clinical entities, which can be caused as complications of amoebic liver abscess. Herein, we report a 45- year old man, who presented with history of hematemesis since last 1 day, melena since last 3 days and fever since last 5 days. On physical examination, he was hemodynamically stable, pallor was noted. Abdominal examination revealed tenderness over the right-upper quadrant. Per-rectal examination showed evidences of melena. Esophagogastroduodenoscopy revealed stomach communicating anteriorly with the abscess cavity from the surrounding, possibly from liver. There was no evidence of fresh bleed during the procedure. The abscess was drained and sent for microbiological evaluation. Computed tomographic angiography revealed a well defined saccular outpouching arising from common hepatic artery with surrounding ill-defined hypodensity around segment V and IVb of liver. Patient underwent transfemoral endovascular coil embolization. Post embolisation, DSA showed complete occlusion of pseudo-aneurysm. He was discharged on oral metronidazole and was doing well on 8-month follow-up with no episodes of rebleed.

A pyogenic hepatic abscess is an uncommon complication after laparoscopic sleeve gastrectomy (LSG) that can develop secondary to an infected hematoma or a staple line leak due to bacterial seeding. Appropriate screening for and management of a pyogenic hepatic abscess are essential in patients with clinical suspicion for complications after LSG. Early diagnosis is essential as pyogenic hepatic abscess can be fatal if not treated early. Only five cases have been reported in the literature so far. We present a case of pyogenic hepatic abscess that occurred two weeks after LSG in a 46-year-old female without immunosuppressive conditions or early postoperative leak. The abscess was diagnosed by computed tomography (CT) and was successfully treated with antibiotics and CT-guided drainage.

Pulmonary arteriovenous fistulae (PAFs) occur congenitally or are acquired. A PAF can cause hypoxemia, sudden death from rupture, abscess formation, and embolism. Treatment for PAF is transcatheter embolization or surgery. Transcatheter embolization is the first choice of treatment; however, this treatment is impossible to perform if a patient has had tricuspid or pulmonary valve replacement. In this paper, we describe a case of PAFs complicated with tricuspid valve replacement with a ball valve (which had been performed 40 years earlier) that was treated with transcatheter embolization.

Aim and background The primary purpose of pilonidal sinus treatment is to minimize complications, accelerate wound healing, and minimize recurrence. However, invasive and minimally invasive methods are being developed to reduce these problems. Early and late postoperative complications remain significant problems in pilonidal surgery. This study aimed to contribute to this issue in surgery by comparing the results of the Karydakis flap (KF) technique and those of the partial primary closure (PPC) technique, to which we applied suture modification. Methods A total of 96 patients diagnosed with pilonidal sinus disease (PSD) were randomly assigned to two groups. Apply the partial primary closure in 46 patients and the Karydakis technique in 50. Results In comparison to the Karydakis technique, the partial primary closure (PPC) group's hospitalization stay was shorter, although the difference was not significant. Healing time was also longer in uncomplicated cases (p = 0.200 and 0.064, respectively). Abscesses and hematomas were not observed with partial primary closure, but the total complication rate was similar to that of the Karydakis technique. Surgical site infections were often seen in the PPC group (21.7% vs. 10%). In contrast, healing time for complicated cases was found to be significantly shorter in the PPC technique (p Conclusion Postoperative abscess, hematoma, and seroma are the most common causes of total wound dehiscence, and delay in wound healing in off-midline techniques. We recommend the PPC technique with suture modification as an alternative to off-midline techniques in clean and chronically infected cases, other than cellulitis, abscess, and purulent discharge cases. However, we primarily recommend off-midline techniques in clean or asymptomatic cases.

Background Patients with Crohn's disease (CD) frequently undergo abdominopelvic computed tomography (APCT) in the emergency department (ED). It's essential to diagnose clinically actionable findings (CAF) as they may need immediate intervention, frequently surgical. However, repeated APCT's includes increased ionizing radiation exposure. Guidance regarding APCT performance is mostly clinical and empiric. Aims We used a machine learning (ML) approach for predicting CAF on APCT in the ED. Methods We performed a retrospective cohort study of patients with CD who presented to the ED and underwent APCT. CAF were defined as bowel obstruction, perforation, intra-abdominal abscess or complicated fistula. ML was used to predict the probability of having CAF on APCT, using routine clinical variables. Results Of 101 admissions included, 44 (43.5%) had CAF on APCT. ML successfully identified patients at low (NPV 91.6%, CI-95% 90.6–92.5) and high (PPV 92.8%, CI-95%, 92.3–93.2) risk for CAF (AUROC = 0.774), using beats-per-minute, mean arterial pressure, neutrophil-to-lymphocyte ratio and sex. This allowed the construction of a risk stratification scheme according to patients’ probability for CAF on APCT. Conclusion We present a novel artificial intelligence-based approach, utilizing readily available clinical variables to better select patients with CD in the ED for APCT. This might reduce the number of APCTs performed, avoiding related hazards while ensuring high-risk patients undergo APCT.

Pseudoaneurysm of the iliac arteries are rarely reported in the literature. Failure to identify the pathology may delay the necessary treatment, and potentially lead to high mortality. We report a case of ruptured mycotic iliac artery aneurysm in a 46-year-old man with newly diagnosed diabetes mellitus. Initial CT appearance mimicked psoas abscess. However, further CT showed features more suggestive of a psoas haematoma with heterogeneous hyperdensities within the lesion. A ruptured mycotic iliac artery aneurysm was diagnosed. Patient was urgently referred to the vascular team for endovascular stenting. Blood-stained purulent material was noted in the left psoas muscle intra-operatively. It was drained and sent for culture, which later yielded Salmonella Enteritidis sensitive to cefotaxime. We present this case to highlight the importance of reviewing any pre-contrast intramuscular hyperdensities which may suggest acute blood content, and raise suspicion of adjacent vascular pathologies.

Objective To identify the appropriate treatment in the tonsillar region's infections, a distinction between tonsillitis with or without abscess formation is essential. Ultrasound proved to be a valuable method in identifying abscess formation in the head and neck region. However, no report described the assessment of the tonsil region. This study aims to determine the feasibility of transcervical ultrasound for abscess visualization in the palatal tonsillar region. Methods Retrospective analysis of 354 patients presenting with clinical suspicion of tonsillar abscess to a tertiary referral center and university hospital. All patients received a transcervical ultrasound to establish a primary diagnosis. The existence of an abscess was confirmed by puncture and incision, or final tonsillectomy. If no abscess could be delineated, non-abscessing tonsillitis was supposed, and conservative primary therapy and closed follow-up examinations were performed. Results After the first diagnostic ultrasound examination, in 257 cases (72.59%), the diagnosis of an abscess could be established, but in 97 cases (27.40%), due to missing abscess formation criteria, non-abscessing tonsillitis was documented. Overall, ultrasonography demonstrated an overall accuracy of 78.8% in this selected cohort. The sensitivity, specificity, PPV, and NPV after the first ultrasound examination were calculated with 75.1%, 88.6%, 94.6%, and 57.3%, respectively. Conclusion The presented data confirm that an abscess formation due to tonsillitis can be detected by transcervical ultrasound, enabling prompt, adequate management. As transcervical ultrasound can be conducted fast and is not associated with radiation, it can be regarded as a first-line diagnostic tool in this condition.

Neoscytalidium is a phytopathogen that is often found in plants and soil. It mostly leads to skin and nail infections, and invasive diseases of the sinuses, lung, and brain have been described mostly in immunocompromised patients. We report a case of a post-renal transplant patient who received anti-thymocyte globulin for induction immunosuppression. A month after her transplant, she presented with fever and new-onset seizures, and computed tomography revealed a brain abscess with mass effects and herniation. The patient underwent abscess drainage and craniectomy. The pathological findings showed filamentous septate hyphae. The surgical culture rapidly grew wool-like colonies with a black reverse on Sabouraud agar. Lactophenol cotton blue staining showing septate branched hyphae with one to two arthroconidia cells with flattened ends. The patient was given a combination of amphotericin B and voriconazole but unfortunately died ten days after the diagnosis. This case highlights Neoscytalidium as a cause of invasive fungal disease in immunocompromised patients that is difficult to treat and is often fatal, even when combined surgical and medical therapies are used as treatment modalities., Highlights • Neoscytalidium spp. is a rare human pathogenic fungal disease that most likely leads to superficial infection. • Immunocompromised host is at particularly higher risk of invasive disease. • This is the fifth case in the literature describing cerebral invasive disease caused by Neoscytalidium spp. • The present case further confirms the aggressiveness of the disease and refractoriness to antifungal therapy. • The diagnoses need to be entertained, especially in an immunocompromised patient and who have history of exposure to agricultural areas.

Summary Envenomation due to a Loxosceles spider bite is a rare event in France and no case concerning the breast has yet been reported. We report the case of a 48-year-old woman who presented at Saint-Etienne University Hospital with a pulsatile pain in her left breast two days after feeling a fleeting bite. An abscess was diagnosed and antibiotics were prescribed. A few days later, a necrotic zone appeared around the areola and 75 percent of the surrounding skin was inflamed. The patient reported a persistent fever and a burning pain in her breast. Loxoscelism was finally concluded and surgical debridement was undertaken, followed by supervised wound therapy and local skin care. Complete healing was achieved after 4 weeks of treatment. The diagnosis of loxoscelism is generally presumptive, as the bite is usually painless and the spider rarely captured. Its diagnosis should be considered when an abscess responds poorly to antibiotics.

While Bartholin gland abscesses are less commonly seen outpatient pathology, prompt diagnosis and treatment are essential to preventing serious complications such as sepsis and rectovaginal fistula. Owing to an unacceptably high recurrence rate, simple incision and drainage is insufficient for primary treatment; preferably, placement of a Word catheter or Jacobi ring device to reepithelize the duct may be done under local anesthesia in an outpatient clinic. Destruction of the gland through silver nitrate application or alcohol sclerotherapy is an alternative. Marsupialization is often reserved for recurrent cases, although can be offered as primary management in some situations.

Infective endocarditis can have peri-annular spread and involve the valvular annulus and adjacent cardiac structures, leading to tissue necrosis and peri-annular abscess. This process may cause pseudoaneurysm formation and other rare and potentially life-threatening complications, so their identification and correct diagnosis are crucial. We describe a case of an 81-year-old woman, with a history of aortic valve replacement and worsening of symptoms, that presents at the imaging a pseudoaneurysm of the aortic root complicated at the same time by 2 life-threatening conditions: fistulization in the Right Ventricular Outflow Tract (RVOT) and the compression of Right Coronary Artery (RCA). This case underlines the importance of imaging, especially Coronary Computed Tomography Angiography (CCTA), in the diagnosis and follow-up of infective endocarditis and its complications, especially in a patient not eligible for surgery.

Objectives: Nipple fissure is considered the second factor responsible for the early cessation of breastfeeding. Untreated nipple fissure leads to several problems, including severe pain, bleeding, inadequate milk excretion, mastitis, and nipple abscess. Design: The present systematic study was designed to review topical treatment for the prevention and relief of nipple fissure and pain in breastfeeding women. Methods: This research included articles found in the electronic databases, including SID, IranMedex, Magiran, Scopus, PubMed, Medline, ScienceDirect, and Cochrane library, published from inception to May 2021. In both Persian and English languages, the searched keywords were sore, nipples, pain, trauma, wound, prevention, treatment, therapeutic, therapy, clinical trial, breastfeeding, herbal and drug. Results: Twenty-two out of 520 found articles were selected for the review, including non-herbal medicines (nine) and herbal products (thirteen). We studied among clinical trials regarding the effects of herbal (olive oil, Aloe vera, Calendula officinalis, jujube oil, mint, frankincense, saqez, and Portulaca oleracea) and non-herbal (lanolin, hydrogels, breast milk, and collagenase) medications on nipple pain and fissure. In twelve studies that people used breast milk to treat and prevent fissure and nipple pain, the results showed the effectiveness of breast milk in improving and preventing fissure and nipple pain. Conclusions: Herbal medications on fissure and nipple pain have also indicated a positive effect on the treatment and prevention of fissure and nipple pain. Still, definitive conclusions about their effects are not possible due to the limited studies.

Graphical abstract, Highlights • A unique case of S. aureus coronary stent infection occurred 5 years after index PCI. • Prompt diagnosis was made with coronary angiography and echocardiography. • Successful treatment included prolonged antibiotics and surgical intervention. • Delayed coronary stent endothelialization might have contributed to late infection.

Background Whether peritoneal lavage is beneficial for the postoperative outcomes of appendectomy is debatable. This study is a meta-analysis of randomized controlled trials (RCTs) that aimed to determine whether peritoneal lavage leads to improved appendectomy outcomes. Methods PubMed, Embase, and Cochrane Library databases were searched for articles published before September 2020. The meta-analysis calculated the pooled effect size by using a random effects model. The primary outcome was the incidence of intra-abdominal abscess. Secondary outcomes were the incidence of surgical-site infection, hospital stay duration, operation time, and readmission incidence. Results Eight RCTs involving 1487 patients were reviewed. The lavage group had a nonsignificantly lower incidence of intra-abdominal abscess (risk ratio [RR]: 0.81; 95% confidence interval [CI]: 0.55–1.18) and surgical-site infection (RR: 0.73; 95% CI: 0.31–1.72) than did the nonirrigation group. Furthermore, the lavage group showed a nonsignificantly shorter hospital stay duration and lower readmission incidence than did the nonirrigation group. However, the lavage group required significantly more operation time than did the nonirrigation group (mean difference: 7.59 min; 95% CI: 4.67–10.50). Conclusion Our study revealed that performing peritoneal lavage has no advantage over suction or drainage only in appendectomy. Moreover, peritoneal lavage significantly increased operation time. Consequently, for improving efficiency and reducing operation time, we suggest skipping peritoneal irrigation during appendectomy. However, the available evidence is of variable quality; therefore, high-quality prospective RCTs are required in the future.

Objective: This study aimed to identify the most commonly reported medical diseases among dental patients and to assess its association with the development of the orofacial abscess. Methods: The medical records (n = 3164) of dental patients who visited the dental hospital at Umm-Al-Qura University (Makkah, Saudi Arabia) were reviewed. Demographic characteristics of eligible patients were collected. Medical diseases were collected as reported by the patients in the medical records. The International Classification of Diseases (ICD-10) was used to classify the reported medical diseases. Simple descriptive statistics were used to define the characteristics of the study variables through a form of counts and percentages. Multivariable logistic regression analysis was carried out to find out the significant predictors of orofacial abscess. Results: Upon reviewing 3164 medical records, almost half of the patients had medical diseases (n = 1543, 49%). The mean age of the cohort was 30.3 (SD = 16.43). Diabetes mellitus (n = 316, 20%) and hypertension (n = 210, 14%) were the most common reported medical diseases. Male patients reported having more medical diseases compared to the female. Hypertension was found to be significantly high among female patients (X2 = 3.167, P-value

This review summarizes the relevant literature for the selection of the initial imaging in 4 clinical scenarios in patients with suspected inflammatory disease or postoperative complication of the anorectum. These clinical scenarios include suspected perianal fistula or abscess; rectovesicular or rectovaginal fistula; proctitis or pouchitis; and suspected complication following proctectomy, coloproctectomy, or colectomy with a pouch or other anastomosis. The appropriateness of imaging modalities as they apply to each clinical scenario is rated as usually appropriate, may be appropriate, and usually not appropriate to assist the selection of the most appropriate imaging modality in the corresponding clinical scenarios of anorectal disease. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Melioidosis, an infectious disease caused by Burkholderia pseudomallei, is endemic in specific regions, including Southeast Asia and Northern Australia. In Japan, where no autochthonous has been reported to date, melioidosis is a rare infectious disease. Herein, we report a case of melioidosis in a 68-year-old Japanese man with renal abscess and bacteremia, but without pneumonia. The patient presented to our hospital and was admitted for fever and chills that have persisted for two months. It was speculated that he was infected in Thailand, where his family lives because he shuttled between Thailand and Japan. Blood cultures on admission identified Burkholderia species; however, the species was unidentifiable by matrix-assisted laser desorption ionization-time of flight mass spectrometry. Further re-examination, including culture, loop-mediated isothermal amplification, and multiplex polymerase chain reaction methods, finally identified Burkholderia pseudomallei. We treated the patient with intravenous ceftazidime for four weeks. In addition to the antibiotics administration, puncture drainage of the renal abscess was performed, and he gradually became afebrile. Intravenous ceftazidime was switched to oral sulfamethoxazole/trimethoprim on post-admission day 32, and he was discharged. After five months of oral sulfamethoxazole/trimethoprim, no recurrence was observed one year after discharge. To diagnose melioidosis, especially in non-endemic areas, a precise and thorough understanding of its epidemiology, presentation, and identification methods is necessary.

Context Acute testicular torsion is a common urological emergency. Accepted practice is surgical exploration, detorsion, and orchidopexy for a salvageable testis. Objective To critically evaluate the methods of orchidopexy and their outcomes with a view to determining the optimal surgical technique. Evidence acquisition This review protocol was published via PROSPERO [CRD42016043165] and conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA). EMBASE, MEDLINE, and CENTRAL databases were searched using the following terms: “orchidopexy”, “fixation”, “exploration”, “torsion”, “scrotum”, and variants. Article screening was performed by two reviewers independently. The primary outcome was retorsion rate of the ipsilateral testis following orchidopexy. Secondary outcomes included testicular atrophy and fertility. Evidence synthesis To our knowledge, this is the first systematic review on this topic. The search yielded 2257 abstracts. Five studies (n = 138 patients) were included. All five techniques differed in incision and/or type of suture and/or point(s) of fixation. Postoperative complications were reported in one study, and included scrotal abscess in 9.1% and stitch abscess in 4.5%. The contralateral testis was fixed in 57.6% of cases. Three studies reported follow-up duration (range 6–31 wk). No study reported any episodes of ipsilateral retorsion. In the studies reporting ipsilateral atrophy rate, this ranged from 9.1% to 47.5%. Fertility outcomes and patient-reported outcome measures were not reported in any studies. Conclusions There is limited evidence in favour of any one surgical technique for acute testicular torsion. During the consent process for scrotal exploration, uncertainties in long-term harms should be discussed. This review highlights the need for an interim consensus on surgical approach until robust studies examining the effects of an operative approach on clinical and fertility outcomes are available. Patient summary Twisting of blood supply to the testis, termed testicular torsion, is a urological emergency. Testicular torsion is treated using an operation to untwist the cord that contains the blood vessels. If the testis is still salvageable, surgery can be performed to prevent further torsion. The method that is used to prevent further torsion varies. We reviewed the literature to assess the outcomes of using various surgical techniques to fix the twisting of the testis. Our review shows that there is limited evidence in favour of any one technique.

Soft tissue swellings, masses, and fluid collections commonly occur in small animal patients and can be the main reason for the clinical examination of the patient or an incidental finding. Several of these masses are likely benign or nonneoplastic, and ultrasound can help further evaluate these lesions to guide treatment planning. Careful attention to optimizing the ultrasound technique and Doppler settings is necessary to ensure that the vascularization of a mass is assessed correctly.

Background/Purpose To assess the use of “quick” MRI without contrast in the setting of percutaneous drain management in pediatric patients. Methods A retrospective medical record review was conducted to compare “quick” MRI without contrast to CT in the pediatric percutaneous drain placement setting. The study included 111 patients under 18-years-old having undergone percutaneous drain placement between January 2014 and January 2019. The “quick” MRI protocol consists of axial single-shot-fast-spin-echo (SSFSE) and fat-saturated SSFSE coronal sequences. Primary clinical outcomes included number of additional drain placement procedures, complications, length of hospitalization, and repeat drainage within 6 months following drain-free interval. The use of “quick” MRI post-procedurally was also investigated. Results Patients with pre-drain “quick” MRIs instead of CTs had no significant difference in the need for additional drain placement (p = 1), length of hospitalization (p = 0.275), or drainage complications (p = 0.728). Patients receiving “quick” MRI for follow-up imaging post-drain placement had no greater rate of repeat drainage within 6 months of initial drain discontinuation (p = 0.90) when compared to patients having CT. Conclusions Pre and post-drainage procedure “quick” MRIs were found to be equivalent to CT in regard to several key clinical outcomes.

Background Abscesses of the chiasmatic-sellar region are quite rare and are often a result of surgical intervention, trauma, or tumor growth. Primary abscesses are extremely rare and represent a group of abscesses the occur because of internal microbial seeding. Primary abscesses are rarely reported. We present 2 clinical cases featuring primary abscesses of the chiasmal-sellar region. To put into perspective the rarity of these findings, we performed a systematic review of existing clinical reports regarding this pathology. Methods A systematic review of literature was conducted to gather existing clinical reports on primary abscesses of the chiasmatic-sellar region. Two personal findings are added to the literature review, including a 13-year-old girl and a 58-year-old man who presented with chiasmal-sellar region primary abscesses. The diagnostic aspects, treatment strategy, and outcomes are discussed. Results Both patients included in the report had positive outcome. The pediatric patient developed a recurrence of the abscess and was treated accordingly. Overall, 41 cases of primary abscesses of this region have been reported in literature, of which 6 are in children under 18 years of age. The main nonspecific clinical manifestations include headaches, visual impairment, and endocrine pathology. Acute inflammatory responses are rarely seen, despite infectious genesis. Transnasal endoscopic surgical treatment offers diagnostic and treatment advantages. Conclusions Proper diagnostic procedures can aid in correct treatment strategy and improve overall outcome.

Cholecystectomy is one of the most common general surgery procedures performed worldwide. Complications include bile duct injury, strictures, bleeding, infection/abscess, retained gallstones, hernias, and postcholecystectomy syndrome. Obtaining a critical view of safety and following the other tenets of the Safe Cholecystectomy Task Force will aid in the prevention of bile duct injury and other morbidity associated with cholecystectomy.

Retrospective videofluoroscopic swallowing study (VFSS) evaluations of pharyngeal swallowing were used to evaluate the types of dysphagia alleviated by the chin-down maneuver.The study population consisted of 64 patients who underwent VFSS evaluations during neutral and chin-down maneuvers presenting specifically penetration or aspiration. The assessment of the VFSS movie clips of each maneuver was performed using parameters of the Modified Barium Swallow Impairment Profile (MBSImP) and the presence and degree of airway invasion(PDAI) by three blinded raters in the following five subcategorized groups, 1. patietns presenting penetration or aspiration during swallow 2. after swallow, patients of 3. head and neck, 4. digestive and 5. neuromuscular disorders, respectively. The scores registered for the two maneuvers were statistically compared. Additionally, we examined statistically which factors had the impact on the improvement of the PDAI using fisher's exact test.Compared with the neutral position, PDAI, pharyngeal constriction, anterior hyoid movement, pharyngeal constriction, laryngeal elevation, laryngeal closure, upper esophageal sphincter opening, initiation of the pharyngeal swallow, and pharyngeal clearance in pyriform sinus were significantly (p0.01-0.05) improved with the chin-down maneuver. In a subcategory comparison with group 1, 3 and 4, the PDAI improved significantly (p0.01) with the chin-down maneuver, in which laryngeal elevation and laryngeal closure had statistically the impact (p0.01-0.05) on improvement of PDAI.The chin-down maneuver was most effective in improving swallow function when the impairment included penetration and aspiration during swallow caused by inadequate laryngeal elevation and laryngeal closure.

Background Little information is published about Vietnamese pot-bellied pig (Sus scrofa domesticus) dentistry. Case Description A Vietnamese pot-bellied pig was presented with a right mandibular abscess. Treatment with oral non-steroidal anti-inflammatory and amoxicillin-clavulanic acid had been initiated by the referring veterinarian. A computed tomography scan was performed and revealed dental abscess of the right mandibular canine (tusk), associated with severe osteomyelitis of mandibular bone. Aberrant tooth growth was suspected, due to the history of attempted tusk extraction and fracture of both mandibular tusks at a young age. A first procedure was performed to extract the right tusk. The reserve crown was exposed through a ventral and dorsal approach. The tooth was sectioned in segments and removed through the surgical accesses. Culture was performed and yielded Fusobacterium necrophorum, Prevotella heparinolytica, Actinomyces hyovaginalis, Escherichia coli and mixed Gram-negative bacilli and anaerobic coccobacilli. Amoxicillin-clavulanic acid was continued for eight weeks after tusk extraction. Four months later, the pig was presented for recurrence of mandibular abscess. A second procedure consisted of debridement and filling of the mandibular cavity with calcium sulfate hemihydrate impregnated with clindamycin hydrochloride. Oral clindamycin was prescribed for three months. No further abscess was reported at seven months follow-up. Conclusions and case relevance This case highlights that tusk extraction in pot-bellied pigs may be associated with severe complications. It also highlights that treatment of pigs with oral necrobacillosis is worth considering before euthanasia. This case report presents a procedure of aberrant mandibular tusk extraction in a pot-bellied pig and is the first documented case of a successful treatment of oral necrobacillosis in a domestic pig.
