Understanding how sensorineural hearing loss (SNHL) impacts postural balance in patients is important, as postural balance predicts the risk of falls.We aimed to clarify the relationship between characteristics in the configuration of audiograms and static postural balance as measured by posturography.We evaluated 385 outpatients (mean [± standard deviation] age, 58.4 ± 18.4 years) with SNHL by audiometry and posturography. Data were analysed by multiple regression models with the outcome of postural sway area with eyes closed (PSA) and predictive variables of audiometric data, adjusted for sex, age and the presence of nystagmus.The increased hearing threshold in the better hearing ear was associated with poorer or higher PSA (beta coefficient [Postural balance in neurotologic patients may be associated with middle-high-frequency hearing levels during ageing.

Treatment strategies for corrosive esophagitis include conservative treatment, such as balloon dilatation at the stenosis site, and surgical treatment. Esophagectomy for corrosive esophagitis is usually performed through the transthoracic or transhiatal approaches. Herein, we report a case of corrosive esophagitis treated with thoracoscopic esophagectomy with the patient in the semi-prone position. The patient was a 48-year-old woman who developed corrosive esophagitis due to accidental ingestion of an alkaline agent. Surgical intervention was required for esophageal stenosis. Therefore, thoracoscopic esophagectomy was performed with the patient in the semi-prone position with bilateral pulmonary ventilation. In our hospital, good operative outcomes have been obtained using thoracoscopic esophagectomy for esophageal cancer with the patient in the semi-prone position with bilateral pulmonary ventilation. This technique is also considered effective for the treatment of corrosive esophagitis.

Combined treatment with bevacizumab and trifluridine/tipiracil (TAS-102) leads to an increased chance of survival in patients with refractory metastatic colorectal cancer (mCRC); however, this treatment is associated with an increased frequency of severe neutropenia (number of neutrophils1,000), which should ideally be managed without dose delays. The present study provided a retrospective review of 35 patients with mCRC, and aimed to elucidate the benefits of prophylactic pegfilgrastim for the treatment of severe neutropenia. Patients received TAS-102 (35 mg/m

The vestibulo-ocular reflex (VOR) in neurotologic patients can be evaluated most quickly by spontaneous nystagmus examinations, and the video Head Impulse Test (vHIT) quantitatively evaluates the VOR of the semicircular canals. We aimed to clarify the concordance and discrepancies between spontaneous nystagmus and vHIT findings, to provide guidance on screening vestibular functions by initial spontaneous nystagmus examination then vHIT. We evaluated 169 outpatients by spontaneous nystagmus examination in the dark using a charge-coupled device camera, then by horizontal vHIT the same day. Vestibular loss on vHIT was defined if both reduced VOR gain (0.8) and corrective saccade were observed. Adjusted logistic regression modelling revealed that differences in right and left VOR gain positively impacted the presence of nystagmus, which suggests lateralised vestibular dysfunction (P0.05; odds ratio 1.39 [95% confidence interval, 1.1-1.8] per 0.1 increment). When vHIT is regarded as the standard clinical test, the positive predictive value of nystagmus for vestibular loss on vHIT was 44.4%, and the negative predictive value was 93.5%. The adjusted odds ratio of adults ≥65 years old compared to younger patients associated with a discrepancy of nystagmus and vHIT was significant (2.4 [1.1-5.3]). In conclusion, if spontaneous nystagmus is initially observed in patients, further assessment by vHIT could confirm vestibular dysfunction in 40-50% of cases. If no nystagmus is observed, vHIT might also result in a negative finding in 90% of cases. Older adults appear more likely to show discrepancies between nystagmus and vHIT.

Genome‑wide DNA hypomethylation is the most common molecular feature in human cancers associated with chromosomal instability (CIN), which is involved in the mechanisms that regulate pancreatic cancer (PC) metastasis. It was investigated whether genome‑wide DNA hypomethylation affects the phenotype in PC via CIN

Despite the acceptance of carbohydrate antigen 19-9 (CA19-9) as a valuable predictor for the prognosis of pancreatic ductal adenocarcinoma (PDAC), its cutoff value remains controversial. Our previous study showed a significant correlation between CA19-9 levels and the presence of KRAS-mutated ctDNA in the blood of patients with PDAC. Based on this correlation, we investigated the optimal cutoff value of CA19-9 before surgery. Continuous CA19-9 values and KRAS-mutated ctDNAs were monitored in 22 patients with unresectable PDAC who underwent chemotherapy between 2015 and 2017. Receiver operating characteristic curve analysis identified 949.7 U/mL of CA19-9 as the cutoff value corresponding to the presence of KRAS-mutated ctDNA. The median value of CA19-9 was 221.1 U/mL. Subsequently, these values were verified for their prognostic values of recurrence-free survival (RFS) and overall survival (OS) in 60 patients who underwent surgery between 2005 and 2013. Multivariate analysis revealed that 949.7 U/mL of CA19-9 was an independent risk factor for OS and RFS in these patients (P = 0.001 and P = 0.010, respectively), along with lymph node metastasis (P = 0.008 and P = 0.017), unlike the median CA19-9 level (P = 0.150 and P = 0.210). The optimal CA19-9 level contributes to the prediction of prognosis in patients with PDAC before surgery.

Highlights • Swallowing corrosive substances leads to gastrointestinal stenosis due to scarification. • Bypass surgery was performed as adhesions posed risk of injury to adjacent organs. • Esophageal bypass with a “supercharged” pedicled jejunal flap was performed. • The technique creates anastomoses between jejunal and internal thoracic vessels. • It is an optimal technique for treatment of stenosis caused by corrosive esophagitis., Introduction Swallowing a corrosive substance causes delayed gastrointestinal stenosis due to scar formation. Here, we report on our use of esophageal bypass using a supercharged pedicled jejunal flap to treat cicatricial esophageal stenosis caused by corrosive esophagitis. Presentation of case Nineteen years before presentation, a 57-year-old man had swallowed a chemical cleaning agent, which caused extensive corrosive cicatricial stenosis from the thoracic upper esophagus to the gastric fornix. An enterostomy had been created, and the patient had since been subsisting on enteral nutrition. However, he wanted to be able to eat through his mouth again and was referred to our department for treatment. With the exception of the cervical esophagus, circumferential cicatricial stenosis was present throughout the esophagus and gastric fornix, with severe adhesions to the surrounding tissue. It was decided not to perform esophagectomy but to perform esophageal bypass surgery using a supercharged pedicled jejunal flap. Discussion Despite the extremely high risk of cancer in the stenotic esophagus due by corrosive esophagitis, indicating that esophagectomy should be performed if possible, we chose to perform bypass surgery because the severe adhesions posed a high risk of early injury to the surrounding organs. Conclusion We suggest that esophageal bypass using pedicled jejunal pull-up “supercharging” by creating anastomoses between the jejunal and internal thoracic vessels is the optimal procedure for patients with extensive cicatricial esophageal stenosis caused by corrosive esophagitis.

Objectives: Subjective symptoms of dizziness in older adults are affected not only by objective data such as postural balance, but also by complex psychological factors. Published data analyzing how simultaneous evaluations of both objective and subjective assessments of balance can predict fall risk remain lacking. This study examined how fall risk can be predicted based on both objective data for balance and hearing and subjective symptoms of dizziness among older adults visiting otolaryngology clinics. Methods: Medical charts of 76 patients ≥65 years old with dizziness/vertigo who visited the otolaryngology clinic were reviewed. Objective data were evaluated by postural balance (posturographic data with eyes open and closed, and one-leg standing test), spontaneous nystagmus, and mean hearing levels. Subjective handicap associated with dizziness/vertigo was assessed using the Dizziness Handicap Inventory (DHI). Subjective mental status of anxiety and depression were assessed using the Hospital Anxiety and Depression Scale (HADS). Information on history (cardiovascular diseases) and fall accidents within the preceding year was collected using an in-house interview sheet. Results: Objective data on postural balance did not correlate with subjective symptoms on DHI or HADS ( P > .05, Pearson’s correlation coefficient). Adjusted logistic regression modeling with the outcome of incident falls revealed that poor postural balance significantly predicted fall risk ( P 2 increment). Nystagmus tended to be associated with fall risk. In contrast, DHI score did not predict fall risk ( P = .43; 1.0 [0.9-1.03]). Receiver operating characteristic analysis proposed a cut-off for postural sway with eyes closed >6.1 cm2 as optimal to predict falls in patients with nystagmus (AUC, 0.74; 95% confidence interval, 0.48-0.997). Conclusion: Poor postural balance is associated with increased fall risk after adjusting for subjective symptoms in older adults at otolaryngology clinics. Conversely, the self-perceived dizziness handicap of DHI score is an insufficient tool to evaluate their fall risk.

We report a rare case of adult intussusception caused by an inverted Meckel’s diverticulum with ectopic pancreatic tissue. A 43-year-old woman was referred to our hospital with complaints of abdominal distention, intermittent abdominal pain and nausea that she experienced 3 months ago. Abdominal computed tomography scans demonstrated ileo-ileal intussusception that contained a tumor with fat density as the lead point. Laparoscopic-assisted partial resection of the small intestine was performed. The surgical specimen showed an elongated polypoid lesion invaginated into the intestinal tract indicating an inverted Meckel’s diverticulum. Pathological findings showed a true diverticulum that ran antimesentrically, with tall columnar epithelium, a mucous gland and an islet of Langerhans. The postoperative period was uneventful, and she was discharged on the ninth postoperative day.

Background Liquid biopsies enable the detection of circulating tumor DNA (ctDNA). However, the clinical significance of KRAS-mutated ctDNA for pancreatic cancer has been inconsistent with respect to its prognostic and predictive potential. Methods and findings A total of 422 blood samples were collected from 78 patients undergoing treatments for localized and metastatic pancreatic ductal adenocarcinoma. KRAS mutation in tissues and KRAS ctDNA levels in plasma were determined by RASKET and droplet digital polymerase chain reaction. Longitudinal monitoring of KRAS ctDNA was performed to assess its significance for predicting recurrence and prognosis and for evaluating therapeutic responses to chemotherapy compared with carbohydrate antigen 19–9 (CA19-9). In 67 tumor tissues, discrepancies in point mutations of KRAS were rarely observed among individual patients, implying that one targeted point mutation of KRAS can be determined in tumor tissues prior to longitudinal blood monitoring. One-time blood assessment of KRAS-mutated ctDNA before surgery or chemotherapy was not clearly associated with recurrence and prognosis. Sequential blood monitoring was performed in 39 patients who underwent surgery for potentially resectable tumors. Increased CA19-9 levels were significantly associated with recurrence, but not prognosis (P

The role of nodal station No. 14v (along the superior mesenteric vein) in lymphadenectomy for distal gastric cancer remains elusive. A 73-year-old woman underwent endoscopic submucosal dissection for gastric cancer, and was referred to our division for additional surgery because of pathologically non-curative resection. A laparoscopic distal gastrectomy with D1+ dissection was performed, with a final diagnosis of pT1bN1M0, Stage IB (2 nodal metastases to No. 6). Four months post-surgery, abdominal computed tomography revealed a 14-mm solitary nodule along the superior mesenteric vein. The lesion was excised and pathologically identified as a lymph node metastasis. Adjuvant chemotherapy with tegafur-gimeracil-oteracil potassium (S-1) was administered for the metastasis. Presently the patient survives without recurrence, 5.5 years after the second operation. Our findings suggest that there is lymphatic flow from the No. 6 to the No. 14v nodal station. Some patients with a No. 6 metastasis may benefit from a No. 14v lymphadenectomy, even in early-staged disease.

Background Anti-epidermal growth factor receptor (EGFR) antibody is widely used for the treatment of patients with metastatic colorectal cancer. Hypomagnesemia is a comparatively frequent adverse event of this drug, which is likely overlooked because it occurs later in treatment without symptoms. Furthermore, hypomagnesemia and hypomagnesemia-induced corrected QT (QTc) prolongation may lead to loss of consciousness (LOC), the onset of which is not generally considered associated with the treatment of anti-EGFR antibody because of its rare occurrence. Here, we present a colorectal cancer patient treated with anti-EGFR antibody, who suffered LOC during treatment while severe hypomagnesemia or QTc prolongation was not observed. Case presentation A 69-year-old man with metastatic colon cancer was treated with cetuximab (anti-EGFR antibody) plus irinotecan as third-line chemotherapy. His serum magnesium level gradually decreased, and grade 2 hypomagnesemia (a serum magnesium level of 0.9 mg/dL) was observed at the 12th administration of cetuximab. In light of this development, intravenous supplementation of 20 mEq magnesium sulfate began with careful blood monitoring despite the lack of clinical symptoms. Electrocardiogram (ECG) showed prolonged QT or corrected QT (QTc) intervals (grade 1). His serum magnesium level remained at 0.9 mg/dL, and no hypomagnesemia symptoms were observed by the 17th administration of cetuximab. After the treatment, however, he suddenly lost consciousness without symptoms related to infusion or allergic reactions. Circulatory collapse following dermatological reactions and respiratory events were not evident. Intravenous supplementation of magnesium sulfate was administered again. He awakened 2 min after the onset of temporary LOC without any other symptoms related to hypomagnesemia, such as lethargy, tremor, tetany, and seizures. No other etiology outside of the low level of serum magnesium was confirmed in further examinations. Cetuximab was discontinued, and his serum magnesium level returned to a level within the normal range after 6 weeks. Because of tumor progression, regorafenib and TAS-102 (trifluridine tipiracil hydrochloride) were introduced sequentially for 6 months. Five months after the final treatment of TAS-102, he died of his primary disease, which reflected a survival period of 4 years and 6 months since the beginning of treatment. Conclusions This case report reminds clinicians that LOC can be induced without severe hypomagnesemia or QTc prolongation, during anti-EGFR antibody treatment for metastatic colorectal cancer even while under carefully monitored magnesium supplementation.

Patients with breast cancer who undergo surgery have a risk of developing multiple cancers in the contralateral breast and other organs. We previously reported that overexpression of satellite alpha transcripts (SAT) facilitates chromosomal instability, which is involved in the development of multiple tumors in patients with colorectal and gastric cancer. In this study, we elucidated the significance of SAT in the development of multiple tumors in patients with breast cancer. Relative expression of SAT (rSAT) was calculated in normal and tumor tissues from 167 patients. In total, 27 patients developed bilateral breast cancer (BBC) and 27 patients showed multiple primary cancer (MPC), with patients with BBC and MPC showing higher rSAT levels in tumor tissues than those in patients with single breast cancer (SBC) (P=0.0312 and P=0.0420, respectively). Additionally, higher rSAT levels in tumor tissues from patients with BBC were a significant factor according to univariate analysis, and multivariate analysis showed that rSAT1.5 was a significant predictor of MPC [hazard ratio (HR): 2.96; P=0.0243); however, we did not clarify the involvement of SAT in normal tissues. Excluding 71 patients with BRCA‑related clinical features, rSAT levels were higher in patients with BBC and MPC than in patients with SBC in tumor tissues and normal tissues (P0.05). Significant predictors according to univariate analysis included rSAT1.5 in tumor tissues, rSAT2.4 in normal tissues, and T2, whereas those for multivariate analysis included rSAT2.4 in normal tissues for BBC (HR: 22.7; P=0.00120) and MPC (HR: 13.0; P=0.00601). Our data indicated that patients with breast cancer and high rSAT levels in their breast tissues exhibit a 10‑ to 20‑fold increased risk for the development of multiple cancers when harboring no BRCA‑related clinical features.

We describe an extremely rare case of tracheal stenosis caused by unnoticed microscopic fiber-like foreign bodies. A 66-year-old woman complained of dyspnea with inspiratory stridor. Magnifying electroendoscopy and computed tomography revealed stenosis involving the entire circumference of the tracheal lumen. Tracheotomy and biopsy were performed. Histologically, the lesion showed chronic inflammation with a deposition of fiber-like foreign bodies. The patient had no history of trauma or inhalation injury, but had undergone intratracheal intubation on 4 occasions. The lesion was incised using semiconductor laser photoresection, and the postoperative course was good. To the best of our knowledge, this represents the first report in the English literature of tracheal stenosis caused by unnoticed foreign bodies. The origin of these fiber-like foreign bodies remains unclear but might be related to chronic inflammation resulting from intratracheal intubations.

Objective The objective of this study was to delineate the frequency of delayed diagnosis in cases of subacute thyroiditis (SAT) and intervals between onset of clinical symptoms and appearance of abnormal laboratory findings. Methods We reviewed the medical records of 27 patients (7 men and 20 women) with SAT who visited our hospital between 2007 and 2013. Results On presentation to the hospital, 5 of 27 SAT cases (18.5%) showed normal laboratory findings. Among these 5 cases, the mean interval between symptom onset and thyrotropin (TSH) suppression was 6.3 weeks, and the mean interval to elevation of fT4 was 6.7 weeks. The longest interval from symptom onset to appearance of an abnormal laboratory finding was 11 weeks. Conclusion Sometimes time-lag exists between onset of clinical symptoms and the appearance of abnormal laboratory findings in patients with SAT. The possibility of this disease should not be excluded from the differential diagnoses for patients with clinical symptoms consistent with SAT but showing normal laboratory findings.

Laparoscopic surgery for obstructive colorectal carcinoma is a controversial issue. Defining the obstructive carcinoma as colonoscopic impassability, the patients with obstructive carcinoma were managed according to the treatment algorithm, by which the indication of open or laparoscopic surgery was determined. As a result, 31 patients with obstructive colorectal carcinoma underwent laparoscopic surgery. The location of the tumor was in the right side in 10 patients and in the left in 21 patients. Preoperatively, all cases were managed by restriction of oral intake and/or decompression. Laparoscopic surgery was completed in 26 cases and colonic obstruction was the direct cause of the conversion in only 1 case. Regarding postoperative complications, there were 3 surgical site infections and 3 instances of postoperative prolonged ileus but no mortality. Oncologically, the primary tumor was completely resected in each case and lymph node harvest (26.6) was adequate.

We describe a rare case of thyroidal Epstein–Barr virus-positive diffuse large B-cell lymphoma of the elderly (EBV+DLBCLe) in which diagnosis was difficult and spontaneous esophageal fistula developed. A 79-year-old woman presented with acute swelling of the anterior neck with tenderness, general fatigue, and continual fever. Malignant lymphoma of the thyroid was suspected. Histologically, the thyroid lesion showed extensive necrosis, including a few Ziehl–Neelsen-positive substances. No evidence of tuberculosis was detected by any other examinations. While performing examinations, left recurrent nerve palsy and a tumorous lesion in the pharynx appeared. Computed tomography and gastrointestinal fiberscopy revealed esophageal fistula. Biopsy specimens from the pharyngeal lesion showed diffuse proliferation of large atypical lymphoid cells that were strongly positive for CD20 and EBV early RNAs. The final diagnosis was thyroidal EBV+DLBCLe with infiltration of surrounding organs. The esophageal fistula had healed 6 months after beginning treatment of EBV+DLBCLe.

Mesenteric leiomyosarcoma is a rare disease with poor prognosis. Previously, mesenteric leiomyosarcoma was not differentiated from gastrointestinal stromal tumor (GIST), which is the most common mesenchymal tumor of the gastrointestinal tract, and several cases of GIST may have been misclassified as mesenteric leiomyosarcoma. Thus, the actual clinicopathological characteristics of mesenteric leiomyosarcomas remain unclear. We herein describe a case of leiomyosarcoma arising in the descending mesocolon in a patient who developed metachronous liver metastasis. A 76-year-old woman reported a mass in her left upper abdomen. Computed tomography imaging revealed a low-density tumor adjacent to the descending colon. The patient underwent surgery and the tumor was resected along with part of the descending colon. Immunohistochemical differential diagnosis revealed that the tumor was positive for smooth muscle actin and desmin, and negative for CD117 (c-KIT) and S-100, which are characteristic of gastrointestinal leiomyosarcoma. A single liver metastasis developed 24 months after the operation. The patient underwent curative resection of the metastatic lesion. Sixteen months following surgery for the liver metastasis and 40 months after the initial removal of the primary lesion, the patient remains disease-free. The prognosis of leiomyosarcoma remains poor and standardized chemotherapy for this rare disease has not yet been established. Early diagnosis and surgical removal of the tumor is the only potentially curative option for liver metastasis of mesenteric leiomyosarcoma.

The case of a 2-year-old boy with a right middle ear lipoma and a concomitant chondroma of the left external auditory canal is presented. The patient's preoperative diagnosis was cholesteatomas of the right middle ear and left external ear canal. A right-sided epitympanotomy was performed. A lump of fatty tissue in the right anterior middle ear cleft that obstructed the Eustachian tube orifice was found. The white mass in the left external auditory canal, which easily separated from the tympanosquamous fissure of the temporal bone, was excised with a Rosen needle. Histopathologic examination revealed a lipoma of the right middle ear and a chondroma of the external ear canal. No cases of concomitant lipoma and chondroma have been previously reported. In the present case, the middle ear lipoma could be classified as a congenital anomaly because of its association with a contralateral side chondroma, which would be a choristoma. 2 Case report The patient was a 2-year-old boy with no complaints who was evaluated by a local otolaryngologist because of right- sided otitis media with effusion. A right-sided myringotomy was performed twice. A yellowish-white mass was observed in the right middle ear at the time of the treatment for the otitis media. The mass did not change in size, form, or color during the course of treatment. The doctor also discovered a white mass in the left external auditory canal, which was suspected to be a congenital cholesteatoma. The patient was referred to our hospital for further evaluation.

Hematoceles are benign hemorrhagic masses. We report three cases of nasal and paranasal sinus hematocele involving prolonged nasal bleeding. Computed tomography (CT) showed an expanding enhanced lesion with a bone defect at the maxillary sinus and magnetic resonance imaging (MRI) varied lesion intensities. We conducted preoperative angiography and selective embolization to be controlled very effectively enabling surgical bleedings. We conducted endoscopic sinus surgery in 1 case and Caldwell-Luc or Denker procedure in 2 cases. We found preoperative imaging to be vital in determining surgical procedures, with preoperative embolization providing an adjunct in estimating vascular proliferation.

IgG4-related disease appears in multiple organs, such as the salivary gland, pancreas, bile duct, and retroperitoneum. It shows elevated serum IgG4 and histopathological IgG4-positive plasma cell infiltration. We report a case of IgG4-related disease of the sinus and nasal cavity. A 70-year-old man complained of left nasal obstruction and nasal bleeding. Computed tomography showed a mass with bone destruction of the left inferior nasal concha and maxillary sinus. Biopsy findings were consistent with IgG4-positive plasma cell infiltration and serum IgG4 was elevated. Inhalation-steroid therapy was very effective in this case with symptoms and local findings relieved in a few months. About 2 years later, the serum IgG4 level had normalized. We concluded that inhalation-steroid therapy was useful in treating for IgG4-related disease of the sinus and nasal cavity, serving as index of curative effect.

Objective Since most patients with peritonsillar abscess (PTA) can be successfully treated with surgical drainage and empirical antibiotic therapy, routine bacteriologic studies for all patients with PTA may be unnecessary. This study tried to evaluate which patients with PTA should certainly undergo bacteriologic studies. Methods Hundred consecutive patients with PTA were treated and underwent culture tests of purulent contents obtained by surgical drainage between April 2008 and December 2013. Results In 62 of the 100 patients, 71 pathogenic bacteria were identified; 61 (86%) were Gram-positive cocci (GPC), 8 (11%) were Gram-negative rods (GNR), and 6 (8%) were anaerobes. Normal flora were isolated in 27 patients, and culture results were negative in 11 patients. Although not significant, primary (without prior antibiotic therapy) case (odds ratio (OR) = 2.19; 95% CI, 0.95–5.05) and laryngeal edema (OR = 2.04; 95% CI, 0.82–5.03) showed a tendency of associations with detection of pathogenic bacteria. After taking into account interactions between smoking habit and laryngeal edema, the covariate-adjusted OR for non-smokers with laryngeal edema was significant and showed a strong relationship (OR = 7.43; 95% confidence interval, 1.05–52.73) compared to non-smokers without laryngeal edema. Conclusion Although empirical antibiotic therapy was effective for most of the PTA patients, bacteriologic studies might be indispensable for the patients with laryngeal edema considering the failure of the first treatments. Particularly, the culture tests may be useful for non-smokers with laryngeal edema.

The parotid tumor has various histopathological findings, and in many cases, it is also difficult to make a diagnosis preoperatively. A clinical study was performed on 153 cases of benign parotid tumor surgically resected between 1994 and 2010. The most common tumor was pleomorphic adenoma, followed by Warthin’s tumor. We compared the preoperative diagnosis based on fine-needle aspiration biopsy with the final diagnosis. We also evaluated any postoperative complications. The predictive value for a specific histologic diagnosis was 94.4% for pleomorphic adenoma, and 94.6% for Warthin’s tumor. The diagnostic accuracy for the histologic diagnosis was 85.9% for pleomorphic adenoma, and 81.5% for Warthin’s tumor. Following the operations, facial paresis occurred in 31 (20.3%) cases, salivary fistula in 9 (5.9%) cases, Frey’s syndrome in 2 (1.3%) cases, and infection in 2 (1.3%) cases. We considered that fine-needle aspiration biopsy was very useful for the surgical management of benign parotid tumors.

Salivary fistula is an uncommon parotid surgery complication. We report a case of prolonged postoperative salivary fistula. Minocycline injection effectively prevented severe complications in refractory salivary fistula. Minocycline has been used in sclerotherapy for chylous fistula following neck dissection, thyroid cyst, parathyroid cyst, etc, and found to be useful in preventing prolonged complications.

Background Few studies have investigated the clinical characteristics of patients with glottic cancer without hoarseness. Methods This retrospective clinical study investigated 371 patients with glottic cancer. Results Thirty-two of the 371 patients (8.6%) with glottic cancer first presented to hospitals with complaints other than hoarseness. Although proportions of stage I and T1 disease were significantly higher among patients without hoarseness than among those with hoarseness (p = .0036 and p = .0004, respectively), survival curves showed no significant differences between groups (p = .1334). Conclusion Patients with glottic cancer without complaints of hoarseness were diagnosed at an earlier stage than those with hoarseness. Accumulation of more cases may lead to better survival of patients with glottic cancer without hoarseness compared to those with hoarseness. Checking the larynx of patients without hoarseness or encouraging internists to check the larynx when performing gastroscopic or respiratory examinations may lead to improvement of glottic cancer prognosis. © 2015 Wiley Periodicals, Inc.

We herein describe the case of an adult with a complicated huge lymphangioma of the small bowel mesentery. Computed tomography (CT) confirmed a 45 × 30 × 14 cm multiple and separate, mixed and solid cystic tumor without enhancement by contrast medium in the abdominal cavity. Mesenteric CT angiography with three-dimensional (3D) reconstruction showed that the tumor did not involve the first jejunal artery, although the tumor did involve the subsequent jejunal and ileal arteries and the corresponding segment of the small bowel. Under anatomic guidance based on mesenteric CT angiography with 3D reconstruction, we were able to successfully excise the tumor. Mesenteric lymphangioma should be excised even when the tumor is asymptomatic. Mesenteric CT angiography with 3D reconstruction is useful for the surgical treatment of huge mesenteric tumors.

Peritonsillar abscess is a frequently encountered otorhinolaryngological emergency, but the characteristics of patients with this disease have not been described in detail. The objective of this study was to delineate prognostic factors associated with peritonsillar abscess and the effects of early surgical drainage for the treatment of peritonsillar abscess. We conducted a retrospective analysis of the medical records of 240 consecutive patients with PTA during the period from 2007 to 2013. Univariate analysis indicated that the period between symptom onset and relief was significantly longer in patients with high levels of C-reactive protein (CRP) (>8.53 mg/dL, p = 0.0073) and without early surgical drainage of pus (p < 0.0001). Multivariate analysis identified both of these values as independently associated with longer duration of symptoms (high CRP, P < 0.0001; no early drainage, P < 0.0001). Univariate analysis indicated that the duration between symptom onset and complete recovery from the disease was significantly longer with age ≥40 years (P = 0.0004), no history of recurrent tonsillitis (P = 0.022), high CRP level (P = 0.0017), and no early surgical drainage of the abscess (P = 0.0014). Multivariate analysis identified older age (P = 0.0004), high CRP level (P = 0.0001), and no early drainage (P < 0.0001) as independently associated with longer duration between symptom onset and complete recovery. Early surgical drainage of the abscess is important for the treatment of peritonsillar abscess. Patients ≥40 years old with peritonsillar abscess and high CRP levels should be recognized as a high-risk group.

Cervical tuberculous lymphadenitis is mainly diagnosed by analyzing tissue samples obtained by fine-needle aspiration (FNA). However, some cases remain diagnostic challenges even after polymerase chain reaction analysis of FNA specimens. To delineate differences between cases that are relatively easy to diagnose and those for which diagnosis is difficult, 22 patients with cervical tuberculous lymphadenitis were studied retrospectively. FNA tissues were used to diagnose 14 cases (group A), whereas excisional biopsy was required for accurate diagnosis of 8 cases (group B). These two groups were compared with regard to results of blood examinations, ultrasound appearance, and various other procedures required to reach the final diagnosis. The results indicated that diagnosis of cervical tuberculous lymphadenitis was more difficult for patients with lower white blood cell counts, lower serum C-reactive protein levels, and absence of lymph node fusion or abscess formation on ultrasonography. The possibility of tuberculosis as a cause of cervical lymphadenopathy should always be considered, even when the presenting symptoms are not typical of this disease.

Introduction Pseudomembranous colitis is known to be caused by Clostridium difficile; and, in 3% to 8% of patients, it lapses into an aggressive clinical course that is described as fulminant. We present here a case of extremely rapid and fatal fulminant pseudomembranous colitis that developed after ileostomy closure, a minor surgical procedure. To the best of our knowledge, this is the first case report of fatal fulminant pseudomembranous colitis after closure of a diversion ileostomy in an adult. Case presentation A 69-year-old Japanese man, who had previously undergone low anterior resection and creation of a diverting ileostomy for stage III rectal carcinoma was admitted for ileostomy closure. Preoperatively, he received oral kanamycin and metronidazole along with parenteral cefmetazole. His surgery and postoperative course were uneventful until the third postoperative day, when fever and watery diarrhea became apparent. The next day he presented with epigastric and left lower abdominal pain. Computed tomography revealed a slightly distended colon. Later that night, his blood pressure fell and intravenous infusion was started. In the early morning of the fifth postoperative day, his blood pressure could be maintained only with a vasopressor. Follow-up computed tomography demonstrated severe colonic dilation. A colonoscopy confirmed the presence of pseudomembranous colitis, and so oral vancomycin was administered immediately. However, within three hours of the administration, his condition rapidly deteriorated into shock. Although an emergent total colectomy with creation of an end ileostomy was performed, our patient died 26 hours after the surgery. The histopathological examination was consistent with pseudomembranous colitis. Conclusion It is important to recognize that, although rare, there is a type of extremely aggressive pseudomembranous colitis in which the usual waiting period for medical treatment might be lethal. We consider that colonoscopy and computed tomography are helpful to decide the necessity of emergent surgical treatment without delay.

Bronchial angiograms performed on 74 patients with pulmonary mass lesion from 1973 through 1977 were reviewed. Angiographic findings of 43 patients with pathologically proven lung cancer were evaluated for histopathology and hilar lymph node metastasis. Angiographic patterns of lung cancer were classified into 6 types. I : Bronchial arterial branches pour into the center of mass density, and then tumor vessels radiate peripherally. II : Neovascularity and tumor stain throughout mass density. III : Neovascularity and/or tumor stain at central portion of mass density. N : Neovascularity and/or tumor stain at peripheral portion of mass density. V : Neovascularity and/or tumor stain at proximal portion of mass density. VI : Non-visualized mass density.Among 25 cases of adenocarcinoma, 16 cases were grouped as type I, 4 as type II, 1 as type N, 2 as type V and 2 as type VI, All the cases showing type I were adenocarcinoma. Fourteen cases of squamous cell carcinoma were classified 8 cases in type II, 1 in type III, 1 in type IV, 3 in type V and 1 in type VI. Small cell carcinoma (non-oat cell type) were 2 cases in type III and 1 in type V.Hilar lymph node metastases were investigated in 35surgically proven cases. Seventeen cases showed angiographic findings of lymph node metastases, and 13 out of these 17 cases were proved to be correct pathologically. Eighteen cases were free of angiographic findings of metastases ;13 cases to be correctly diagnosed and 5 cases showed metastasis pathologically.
