To develop a treatment and management algorithm for vulvar abscess.We evaluated the clinical findings and treatment modalities of patients hospitalized with vulvar abscess via a comprehensive literature review and a clinical study. Patients with a diagnosis of vulvar abscess (n = 28) between 2015 and 2019 in the gynecology clinic of our hospital were included in the clinical study. Each patient's age, obstetric history, body mass index, presence of concomitant diseases, abscess culture and size, mean length of hospital stay, treatment modalities, and recurrence rate were recorded.The mean age and body mass index of the patients were 47.7 ± 11.5 years and 30.3 ± 2.7 kg/mThis is the first study in the literature to present a successful algorithm for the treatment and management of vulvar abscess. Our treatment methods shed light on the treatment and management of vulvar abscess.

BACKGROUND People who inject drugs (PWID) are known to be at increased risk of infectious diseases including bacterial and blood-borne viral infections. However, there is limited literature surrounding the burden of spinal infections as a complication of injecting drug use (IDU). AIMS To quantify the clinical and financial burden of IDU-related spinal infections. METHODS Retrospective chart review of adult PWID with spinal infections requiring hospital admission to a tertiary health service in Melbourne, Australia between 2011 and 2019. RESULTS Fifty-seven PWID with 63 episodes of spinal infections were identified with a median hospital stay of 47 days (IQR 16, range 4-243). One-third of episodes required neurosurgical intervention and 11 episodes (17%) required intensive care unit (ICU) admission (range 2-17 days). Staphylococcus aureus was the most common causative pathogen, present in three-quarters of all episodes (n = 47). The median duration of antibiotic regime was 59 days (IQR 42) and longer courses were associated with known bacteraemia (p = 0.048), polymicrobial infections (p = 0.001) and active IDU (p = 0.066). Predictors of surgery include neurological symptoms at presentation (RR 2.6; p = 0.010), inactive IDU status (RR 3.0; p = 0.002), a diagnosis of epidural abscess (RR 4.1; p = 0.001) and spinal abscess (RR ∞; p

BACKGROUND: There is a relative paucity of data examining the prevalence of renal pathology in wild rabbits. METHODS: Sixty-two wild rabbits that had been shot for population control in Cambridgeshire, UK, underwent postmortem examination, including macroscopic and microscopic renal assessment. RESULTS: The majority (82%) of the animals had macroscopically and microscopically normal kidneys. One animal (1.6%) had severe perirenal abscessation. Pasteurella spp. was isolated from this lesion. Ten rabbits (16%) had microscopic renal pathology comprising minimal to mild renal inflammation or fibrosis. No Encephalitozoon cuniculi organisms were detected histologically. LIMITATIONS: The sample population was composed of shot rabbits, so the probability of detecting moribund individuals was reduced. Extrapolation of these data to the wider UK wild rabbit population may be limited as rabbits were shot at two sites within a 3 km radius of each other. CONCLUSION: Renal pathology is rare in the population examined.

Hypaxial muscle abscess is an important differential in dogs presenting for abdominal or back pain, lameness, and nonspecific signs like fever, lethargy, and hyporexia. It can occur concurrently with intrathoracic disease such as pyothorax secondary to migrating vegetal foreign material. Twelve dogs that underwent CT of the lumbar spine or abdomen and had a diagnosed hypaxial abscess on surgical and/or microbiological examination were included in this retrospective, descriptive case series. Computed tomography findings and findings from other imaging modalities employed were described. Eleven dogs were hunting breeds. Clinical signs included lethargy, fever, increased respiratory effort, and abdominal or back pain. Radiography and/or ultrasonography were employed during preliminary work up at clinician discretion and respectively revealed changes consistent with osteomyelitis in the cranial lumbar vertebrae and heterogenous, hypoechoic areas in the hypaxial musculature consistent with abscesses. Computed tomography findings included enlargement of hypaxial muscles with well-defined fluid attenuating noncontrast enhancing areas with a contrast-enhancing rim consistent with abscesses, periosteal reaction and lysis of vertebrae, and retroperitoneal effusion. Four of the 12 cases in this series had material identified and removed at surgery. The other eight cases were presumed to be the same disease process based on compatible signalment, imaging findings, and microbiological results. Migrating vegetal foreign bodies are a common problem at the authors' institution. Computed tomography provided expedient, thorough visualization of the relevant hypaxial lesions for diagnostic and surgical planning purposes and also characterized intrathoracic components of this disease.

The main aim of the study was to evaluate the inflammatory response and development of apical periodontitis in rats chronically treated with glucocorticoids.Male Wistar rats (Rattus novergicus) were randomly divided into two groups: the experimental group, which was treated with prednisone (5 mg/kg/day) and a control group, which was administered saline solution for 30 days before induction of apical periodontitis, continuing until the day of euthanasia days 0, 7, 14 and 28 after injury induction. The mandibles were subjected to histological evaluation to determine the size of the lesion, was also performed for the presence and absence of pulp necrosis, bone resorption and micro abscesses, and histomorphometric analyses were performed based on the number of polymorphonuclear cells and mononuclear cells. Histochemical analysis was also performed to assess the percentage of collagen fibres and their typification, in addition to immunohistochemistry for the inflammatory markers interleukin IL-1β, IL-6, TNF-α and TRAP.Despite after 7 days, there was no differences between groups, a significant increase in the root pulp necrosis (p = .001), micro-abscesses (p = .026) and the size of the apical lesion on the 14th day of treatment with prednisone (p = .008). On the same day, there was also an increase in the number of polymorphonuclear cells (p = .042) and cells immunostained for IL-1β (p = .006), IL-6 (p .001) and TRAP (p = .002) in animals treated with prednisone. The numbers of mononuclear cells also increase in 28 days (p = .025) and TNF-α ± increases in the prednisone group on the 7th day (p = .041). The prednisone group also showed a decrease in collagen after 14 (both type I [p = .041] and type III [p = .046]) and 28 type III (p = .002) days after the coronary opening.The glucocorticoids modified the development of experimental apical periodontitis induced in rats, causing an early increase in periapical bone resorption and pulp necrosis. These effects are associated with alterations in cytokine levels, in the inflammatory response and in collagen deposition, in the 14th day after injury induction.

Systemic sclerosis (SSc) is an autoimmune connective tissue disorder characterized by skin fibrosis, vasculopathy, and dysimmunity. Data regarding osteitis in SSc are scarce.We performed a nationwide multicenter, retrospective, case-control study including patients with SSc, according to the 2013 American College of Rheumatology/European Alliance of Associations for Rheumatology classification, with a diagnosis of osteitis. The objectives of the study were to describe, to characterize, and to identify associated factors for osteitis in patients with SSc.Forty-eight patients were included. Twenty-six patients (54.1%) had osteitis beneath digital tip ulcers. Physical symptoms included pain (36 of 48, 75%), erythema (35 of 48, 73%), and local warmth (35 of 48, 73%). Thirty-one (65%) patients had median (interquartile range) C-reactive protein levels2 mg/liter of 8 (2.7-44.3) mg/liter. On radiography, computed tomography, or magnetic resonance imaging, osteitis was characterized by swelling or abscess of soft tissues, with acro-osteolysis or lysis in 28 patients (58%). Microbiological sampling was performed in 45 (94%) patients. Most pathogens were Staphylococcus aureus (43.8%), anaerobes and Enterobacteriaceae (29.1%), and Pseudomonas aeruginosa (10.4%). Management comprised antibiotics in 37 (77.1%) patients and/or surgery in 26 (54.2%). Fluoroquinolones were used in 22 (45.8%) patients, and amoxicillin plus β-lactamase inhibitor in 7 (14.6%). Six (12.6%) patients relapsed, 6 (12.6%) patients had osteitis recurrence, 15 (32%) sequelae, and 2 patients had septic shock and died.This study confirmed digital tip ulcers as an associated factor for osteitis and revealed a high rate of functional sequelae. Antimicrobial therapy with oral fluoroquinolone or intravenous amoxicillin and β-lactamase inhibitor are used as first-line antibiotic therapy in SSc patients with osteitis.

To compare contrast-enhanced transabdominal ultrasonography (CE-US) following contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS) with enhanced magnetic resonance imaging using gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (EOB-MRI) in the diagnosis of liver metastases in patients with pancreatic cancer.Patients who underwent contrast-enhanced computed tomography for possible pancreatic cancer and required further evaluation with CH-EUS were enrolled in this study, and the diagnostic performance of CE-US following CH-EUS for liver metastasis was compared with that of EOB-MRI.A total of 228 patients were included in the final analysis. Two hundred thirty-four hepatic lesions were found in 81 patients, and 178 lesions were finally diagnosed as metastases. EOB-MRI had a higher sensitivity (0.837 vs 0.949), while CE-US had a higher specificity and positive predictive value (PPV) (0.982 and 0.993 vs 0.911 and 0.971, respectively) in the diagnosis of liver metastasis. CE-US with defect reperfusion imaging had a higher diagnostic performance than EOB-MRI (0.866 vs 0.667) in the differentiation between liver metastasis and abscess.EOB-MRI had a higher sensitivity than CE-US for diagnosing liver metastasis in patients with pancreatic cancer, but CE-US following CH-EUS demonstrated a higher specificity and PPV than EOB-MRI and was especially useful in the differentiation between liver metastasis and abscess.

To describe the clinical presentation, CT imaging findings, surgical treatment and long-term outcome in dogs with sublumbar abscessation.Medical records of dogs treated for sublumbar abscessation between 2013 and 2019 were retrieved. Criteria for inclusion were a diagnosis of sublumbar abscessation, complete patient history, pre-operative CT imaging, blood work, bacteriology results, record of the surgical treatment, post-operative care and outcome.Sixteen dogs were included in this study with a median follow-up period of 36 months (15/16). Clinicals signs included flank or lumbar soft tissue swelling (12/16), lumbar pain (11/16), hyperthermia (8/16), a cutaneous discharging sinus (5/16) and lethargy (5/16). CT findings were: abscesses of varying size localised in the psoas muscles (16/16), spondylitis (12/16), vertebral osteomyelitis (6/16), discospondylitis (2/16) and epidural inflammation (8/16). Thoracic lesions were present in eight of 12 dogs. Exploratory surgery was performed in 16 dogs via a midline celiotomy in 15 of 16 and a lateral approach in one of 16 cases. The surgical approach was selected based on the location of the draining tracts detected on CT imaging. Vertebral body curettage was performed in five of 16 cases with lesions identified on CT. Vegetal foreign material was found in seven of 16 dogs. Of the 15 animals with long-term follow-up, 13 had no signs of recurrence.Surgical treatment of sublumbar abscessation resulted in a good long-term outcome when CT was used to guide the surgical approach and to plan the procedure. Our study highlights common vertebral and epidural lesions associated with sublumbar abscesses with a prevalence of 87.5%.

A 79-year-old man, who underwent femoropopliteal bypass surgery 1 month prior to admission, presented with fever and fatigue. ECG showed complete atrioventricular block. Transthoracic echocardiography was performed, revealing a round homogeneous right atrial mass and severe mitral regurgitation. Transoesophageal echocardiography revealed involvement the coronary sinus (CS). Computed tomography imaging demonstrated abscess of the atrioventricular sulcus and infiltration of the CS.

Brain abscesses due to odontogenic infection are infrequent, but they deserve attention due to the high incidence of serious complications and the high mortality rate. This article aimed to report five cases of cerebral abscess due to odontogenic infection, of patients attended in the Clinical Hospital of Medical School of the University of Sao Paulo (HCFMUSP). In all cases, treatment consisted of draining the brain abscess, antibiotic therapy and extraction of all teeth responsible for the infection. Streptococcus sp. was the causative agent of all the cases reported in this article. The purpose of the study was to highlight the importance of the dental approach for the resolution of cases.

Background Appendiceal neurendocrine tumours (NETs) are rare neoplasms and diagnosis is commonly incidental following appendectomy. We aimed to review our experience with appendiceal NETs. Methods Records of children with appendiceal NETs were reviewed and data concerning demographic characteristics, clinical findings, surgical procedures, histopathological findings, management and outcomes were recorded. Results Between 1985 and 2021, 33 cases with appendiceal NETs (median age 11.8 years, range 7.8-16; male/female = 10/23) were identified. All but one patients presented with abdominal pain, six had vomiting, four had fever and they underwent appendectomies with presumed diagnosis of acute appendicitis. Abscess drainage and appendectomy was performed in a 16-year-old girl for suspected right ovarian mass, and tumour was positive in the omentum. Histopathological diagnosis was classical carcinoid tumour (NET) in all cases. Median tumour size was 0.9 cm (n = 26, range, 0.1-3.5 cm); tumours were ≤1 cm in 19 cases, 2 cm in one, 3.5 cm in another case. Tumours were located in the tip (n = 11), body (n = 6) and base of appendix (n = 1) (in others data unavailable). In 28 patients with data, tumour extended to submucosa in five, to tunica muscularis in seven, to subserosa in six, to serosa in six, to mesoappendix in three, to periappendiceal fat in one. Three cases were lost to follow-up, 31 cases were alive (median follow-up 53 months). Conclusions Paediatric appendiceal NETs do not behave aggressively and appendectomy alone is sufficient for tumours ≤2 cm regardless of local invasion. The need for further extensive surgery in tumours >2 cm also remains controversial.

OBJECTIVE To create a risk scoring system comprised of clinical and radiological characteristics that can predict the likelihood of antibiotic treatment failure of tubo-ovarian abscesses. The score should guide clinicians in identifying patients to whom early intervention should be offered instead of a prolonged trial of antibiotics. METHODS A multicenter, retrospective cohort study carried out between January 1, 2013 and September 30, 2019, identified consecutive patients with tubo-ovarian abscess. Using a chronological split, patients were allocated to two groups for the development and subsequent validation of the postulated scoring system. Univariate and bivariate analyses were performed to identify statistically significant variables for the failure of intravenous antibiotic treatment. RESULTS In total, 214 consecutive patients with tubo-ovarian abscesses were identified. Data from the first 150 patients were used for the development of the postulated scoring system; data from the subsequent 64 patients were used for validation. Statistically significant clinical features between those having successful and unsuccessful management were: temperature (median = 37.1℃ vs 38.2℃, P = 0.0001), C-reactive protein (151 mg/L vs 243 mg/L, P = 0.0001), and tubo-ovarian abscess diameter (6.0 cm vs 8.0 cm, P = 0.0001). These parameters were used to create a risk prediction score. A score of four or more was predictive of requiring surgical/radiological intervention of tubo-ovarian abscess (P

BACKGROUND: Hidradenitis suppurativa (HS), a chronic, recurrent, debilitating skin disease, is characterized by painful, inflammatory, subcutaneous lesions of the axilla, inguinal and anogenital regions. Overall prevalence of HS is ˜1%, and the impact of disease on patient quality of life (QoL) and healthcare resource utilization (HRU) is high. OBJECTIVES: To estimate the real-world effectiveness of adalimumab (Humira®) treatment in patients with moderate-to-severe HS on disease severity, pain, QoL, work productivity and HRU. METHODS: HARMONY (Effectiveness of Adalimumab in Moderate to Severe HidrAdenitis SuppuRativa Patients - a Multi-cOuNtry studY in Real Life Setting) is a multicentre, postmarketing observational study in adult patients with moderate-to-severe HS. Disease severity and QoL parameters were evaluated using validated measures at 12-week intervals over 52 weeks of treatment. The primary endpoint was the proportion of patients achieving a Hidradenitis Suppurativa Clinical Response (HiSCR: ≥50% reduction in abscess and inflammatory nodule count, with no increase in abscess and draining fistula counts relative to baseline) at 12 weeks. Secondary endpoints were HiSCR at 24, 36 and 52 weeks and changes in QoL parameters and work productivity assessments. Analyses were conducted using as-observed data. RESULTS: The proportion of patients reaching the primary HiSCR endpoint was 70.2% (n = 132/188 enrolled) and remained ≥70% until study completion. There were statistically significant (P < 0.0001) reductions in worst and average skin pain. All of the QoL measures evaluated improved significantly (P < 0.0001) by 12 weeks of adalimumab treatment, as did work productivity assessments (P < 0.05), and there was a ˜50% decrease in HRU between baseline and week 52. Adalimumab was well tolerated. CONCLUSIONS: In this real-world setting, adalimumab treatment of moderate-to-severe HS resulted in decreased disease severity and improvements in QoL and productivity. Response to adalimumab was rapid (within 12 weeks) and sustained (52 weeks). No unexpected safety signals were reported.

Perianal abscesses are a common surgical emergency. Due to their perceived ease, drainage is often delegated to junior trainees with varying levels of experience. The purpose of this study is to evaluate the current trend in perianal abscesses management at our institution, and identify factors that predict subsequent fistula formation or abscess recurrence.All acute patients admitted to a major teaching hospital who required surgical drainage of a perianal abscess were analysed over a two-year period from January 2019 to December 2020. Patient demographics, clinical and laboratory findings were retrospectively reviewed. Proceduralist experience, operative management strategy and recurrence rates (fistula or abscess) were analysed.The mean age of patients was 43 years old, and 73% were male. Trainees performed 96% of the procedures. Re-presentation with a fistula or abscess recurrence requiring further surgery was 31%. Comorbidities of IBD, diabetes, or malignancy were present in one-third of patients and significantly increased the risk of recurrence (P = 0.01). Searching for a fistula tract was performed in 41% of cases but did not reduce recurrence (P = 0.9). Seton insertion occurred in 10%, and fistulotomy in 2%.Perianal abscess drainage at our institution is almost exclusively performed by trainees, the majority of which occurs after-hours. Patients who present with a fever, inflammatory bowel disease, diabetes mellitus or malignancy are at an increased risk of recurrent abscess or a subsequent fistula after drainage, and input from an experienced surgeon may be of value when considering seton insertion or fistulotomy.

Objective To report a multicenter experience with the management of urachal abscess treatment in Japan. Methods This was a retrospective study of 263 cases of urachal abscess managed at 12 university hospitals in the Kyushu-Okinawa region over a 10-year period. Age, sex, abscess size, clinical symptoms, type of urachal remnants, and treatment were collected and analyzed. Results The average age was 29.8 ± 18.1 years, with males accounting for approximately two-thirds of the study population. The average abscess size was 1.7 cm (range 0-11 cm). The most common presenting symptom was umbilical secretion (66%), followed by abdominal pain (46%). A total of 127 patients (48.3%) were treated with antibiotics alone, whereas 136 patients (51.7%) received surgical treatment. The surgical approach was laparotomy in 75 patients (61.0%) and laparoscopic surgery in 48 patients (39.0%). Regarding the type of urachal remnant, the urachus sinus (180 patients) accounted for 68.4% of the total. Conclusions To our knowledge, this study represents the first report on urachal abscess treatment in Japan. Our data show that the clinical symptoms might vary depending on the type of urachus remnant. It should be noted that gross hematuria, a characteristic symptom of urachal cancer, is rare in patients with urachal abscess.

OBJECTIVES There are three surgical treatment options for patients with peritonsillar abscess (PTA): needle aspiration, incision and drainage (ID), and abscess tonsillectomy (ATE). The updated German national guideline (2015) included changes in the treatment of PTA. The indication for tonsillectomy (TE) in patients became more stringent and preference was given to ID in certain cases. STUDY DESIGN Retrospective analysis. METHODS We performed a retrospective systematic analysis of patient data using the in-house electronic patient records and considered a 4-year period from 2014 to 2017. About 584 patients were identified. Our aim was to analyze the influence of the updated guideline on clinical practice. RESULTS 236 of 584 patients (40.4%) underwent ATE with contralateral TE. In 225 patients (38.5%), unilateral ATE was performed. Mean surgery time was significantly shortened when only unilateral ATE was performed. Concerning postoperative bleeding, we noted a tendency toward a lower incidence after ATE in comparison to ATE with contralateral TE. Less than 1% of patients who underwent ATE had to be revised surgically due to postoperative hemorrhage. After the revision of the guideline, unilateral ATE and ID were conducted more frequently. CONCLUSION These results support that ATE in an inpatient setting is a considerably safe and effective primary therapeutic option. ID represents a favorable treatment option for patients with PTA and comorbidities, nevertheless, patient compliance is required and insufficient drainage or recurrence of PTA may occur. The revision of the guideline had a significant impact on the choice of interventions (P
