Bromidrosis is a disorder characterized by rancid body odor which influences a patient's social life and mental health. The therapeutic modalities and the mechanism of bromidrosis have been carefully studied, however, there have been few reports about the genetic inheritance of bromidrosis. We investigated the family history of 42 patients who were operated on for bromidrosis and followed up to the third generation in 10 cases. The results were as follows: Results of investigation which were followed up the second generation. The fathers of five patients and the mothers of 11 patients had bromidrosis in 18 male patients. The fathers of six patients and the mothers of 12 patients had bromidrosis in 24 female patients. Thirty-four patient (81.0%) among a total of 42 have a single parent with bromidrosis. Result of investigation which were followed up to the third generation Bromidrosis was occurred in 17 of 42 patients (40.5%) in the second generation, and 18 of 27 patients (66.7%) in the third generation. In one case, a father transmitted bromidrosis to his three sons, and as a result, X-linked inheritance could be ruled out Bromidrosis was not skipped in every generation of all families. We on conclude that bromidrosis is an autosomal dominant inherited disorder.

PURPOSE: The goal of this study was to evaluate the diagnostic accuracy of preoperative fine needle aspiration biopsy cytology (FNAB-C) in predicting lateral lymph node metastasis in papillary thyroid cancer patients. METHODS: A total of 592 patients who underwent thyroid cancer surgery and intra-operative lateral cervical LN frozen section or RND, from January 2002 to December 2011, were evaluated retrospectively. Among them, 228 cases had suspicious findings in FNAB-C of lateral nodes. We reviewed their radiological and pathological reports. RESULTS: Intra-operative frozen section examination was performed in 540 cases and RND was performed in 314 cases. This study included 534 women (83.4%) and 106 men (16.6%). Patients' ranged in age from 9 to 83 years (mean, 45.65 years). FNAB-C was performed in 228 cases. The sensitivity and specificity of FNAB-C was 71.5% and 78.6%, respectively; 35.9% of cases had a false negative result. The combination of FNAB-C and intra-operative frozen section test sensitivity and specificity was 87.2% and 93.6%, respectively. CONCLUSION: The results for sensitivity in FNAB-C actually appear low, and false negative results were very high. In papillary thyroid cancer in patients with FNAB-C, even if the result is negative, if lymph node metastasis is suspected based on radiologic evidence, frozen section examination should be performed for determination of metastasis.

Acute interstitial pneumonia is a fulminant disease of unknown etiology that usually occurs in a previously healthy person and produces the histologic findings of the organizing phase of diffuse alveolar damage. We experienced an autopsy case of acute interstitial pneumonia of unknown etiology. The patient was a 48 year old man who had been healthy and had not been exposed to organic dusts or other toxic materials. The chief complaints represented were dyspnea and a dry cough for several weeks before hospitalization, and the chest radiographs showed bilateral interstitial infiltrates. Patchy consolidation of air space was also identified and ground-glass attenuation similar to those described in ARDS was detected on high-resolution computed tomography. Steroid pulse therapy, mechanical ventilation, and antibiotics for superimposed bacterial infection were performed, but the symptoms did not improve and the patient died of generalized respiratory insufficiency and severe hypoxemia 2 1/2 months after hospitalization. At autopsy the macroscopic and microscopic findings were confined mainly to the lungs. On the whole, both lungs were firm in consistency and the external surface showed a cobblestone appearance. The cut surface showed almost complete replacement of the normal lung parenchyma with gray to yellow fibrous tissue with a little residual functional area remaining. The pathology of both open lung biopsy and autopsy tissue showed marked hyperplasia of type II pneumocytes, hyaline membrane formation, thickening of the alveolar wall due to extensive fibroblast proliferation, and relatively abundant young collagen deposition in the interstitium. An immunohistochemical stain for cytokeratin revealed epithelial hyperplasia and showed that the alveolar spaces were markedly shrunken by fibrous tissue.

Most patients with thyroid cancer (of follicular cell origin) are successfully managed with a combination of surgery, radioactive iodine (131I-RAI), and suppression of thyroid-stimulating hormone with thyroid hormone replacement, obtaining survival rates approaching 90% at 20 years. Although the prognosis of patients with differentiated thyroid carcinoma (DTC) is favorable, recurrence occurs in up to 30% patients. In addition, many patients with recurrent or metastatic disease, as well as those with less differentiated tumors, will have a much poorer prognosis and lose their ability to concentrate functional iodine and are therefore not targeted by 131I-RAI therapy. There are many treatment options but no definitive treatment for radioiodine refractory thyroid cancer. This paper will discuss the roles of surgical treatment for patients with radioiodine refractory thyroid cancer.

Objectives:
. To determine the appropriate anatomical borders of implantation on the temporal bone in a cadaver study, and to develop a simplified surgical technique for Baha Attract implantation through a small incision along the hairline using anatomical evidence and a navigation system.
Methods:
. In a cadaver study, 20 human adult dry skulls were used to find flat areas of the temporal bone for Baha Attract magnet implantation. Four borders of the “optimal surgical site” were defined: Asterion line, occipitomastoid suture line, sigmoid sinus line, and digastric groove line. In three patients, we implanted the Baha Attract according to the newly developed surgical procedure and validated the feasibility of this technique with a navigation system.
Results:
. We identified the appropriate position of the implant on the temporal bone, suggesting a simplified surgical technique for Baha Attract with a small incision. We determined the spot of implantation, and the implants were inserted through a small surgical incision (<2.5 cm) under local anesthesia; the procedure lasted approximately 30 minutes.
Conclusion
. The optimal surgical site of the temporal bone is a safe and easily accessible location for implantation of the Baha Attract.

PURPOSE: The goal of this study was the early diagnosis of ABCB11 spectrum liver disorders, especially those focused on benign recurrent intrahepatic cholestasis and progressive familial intrahepatic cholestasis. METHODS: Fifty patients presenting neonatal cholestasis were evaluated to identify underlying etiologies. Genetic analysis was performed on patients suspected to have syndromic diseases or ABCB11 spectrum liver disorders. Two families with proven ABCB11 spectrum liver disorders were subjected to genetic analyses to confirm the diagnosis and were provided genetic counseling. Whole exome sequencing and Sanger sequencing were performed on the patients and the family members. RESULTS: Idiopathic or viral hepatitis was diagnosed in 34%, metabolic disease in 20%, total parenteral nutrition induced cholestasis in 16%, extrahepatic biliary atresia in 14%, genetic disease in 10%, neonatal lupus in 2%, congenital syphilis in 2%, and choledochal cyst in 2% of the patients. The patient with progressive familial intrahepatic cholestasis had novel heterozygous mutations of ABCB11 c.11C>G (p.Ser4*) and c.1543A>G (p.Asn515Asp). The patient with benign recurrent intrahepatic cholestasis had homozygous mutations of ABCB11 c.1331T>C (p.Val444Ala) and heterozygous, c.3084A>G (p.Ala1028Ala). Genetic confirmation of ABCB11 spectrum liver disorder led to early liver transplantation in the progressive familial intrahepatic cholestasis patient. In addition, the atypically severe benign recurrent intrahepatic cholestasis patient was able to avoid unnecessary liver transplantation after genetic analysis. CONCLUSION: ABCB11 spectrum liver disorders can be clinically indistinguishable as they share similar characteristics related to acute episodes. A comprehensive genetic analysis will facilitate optimal diagnosis and treatment.

PURPOSE: Gastric cancer surgery is a common operation in East Asia, such as Korea and Japan, and there has been a significant increase in the need for this procedure due to the aging population. As a result, surgery for the treatment of gastric cancer for elderly patients is expected to increase. This study examined the effect of old age on gastric cancer surgery, and analyzed the operative risk factors for elderly patients. MATERIALS AND METHODS: From November 2008 to August 2010, 590 patients, who underwent a curative resection for gastric cancers, were enrolled. Patients who underwent palliative or emergency surgery were excluded. A retrospective analysis of the correlation between surgical outcomes and age was performed. The elderly were defined as patients who were over the age of 65 years. RESULTS: The mean age of all patients was 58.3 years, and complications occurred in 87 cases (14.7%). The most common complication was wound infection and severe complications requiring surgical, endoscopic, or radiologic intervention developed in 52 cases (8.8%). The rate of complications increased with increasing age of the patients. Univariate analysis revealed age, comorbidity, extent of resection, operation time, and combined resection to be associated with surgical complications. In particular, age over 75 years old, operation time, and comorbidity were predictive factors in multivariate analysis. In the elderly, only comorbidity was associated with surgical complications. CONCLUSIONS: The patients' age is the most important factor for predicting surgical complications. Surgeons should pay an attention to the performance of gastric cancer surgery on elderly patients. In particular, it must be performed carefully for elderly patients with a comorbidity.

In July 2012, philometrid nematodes were discovered in cultured rockfish (Sebastes schlegeli) in Cheonsuman (Bay), the Republic of Korea. The nematodes were detected in the epithelial tissues of the rockfish and were identified as Clavinema mariae based on morphological studies using light and scanning electron microscopy. They revealed the characteristics same as previously identified C. mariae, notably having a long body with narrow posterior half, no caudal projection, a cylindrical-shaped esophagus, a well-developed anterior bulbous part of the esophagus, cephalic papillae, and a dorsal esophageal gland. This is the first confirmation of C. mariae infection in rockfish in Korea.

We treated a family of 3 brothers with prostate cancer, which is the first report of familial prostate cancer in Korea. Prostate cancer was diagnosed in the first brother with a prostate-specific antigen (PSA) level of 12.70 ng/ml of at the age of 68 years. He underwent a radical retropubic prostatectomy (RRP); the cancer was pathologically staged to T2cN1Mo. He received adjuvant hormonal therapy postoperatively. Three years later, prostate cancer was diagnosed in the third brother at the age of 61 years with a high PSA level of 4.45 ng/ml. He underwent RRP, which revealed the pathological stage to be T2cN0M0. Three months later, the second brother, who had visited our hospital for lower urinary tract symptoms and for a PSA screening test was diagnosed with prostate cancer at the age of 60 years (PSA level of 3.96 ng/ml). He also underwent RRP, and his cancer was staged pathologically as T2cN0M0.

BACKGROUND: Propofol (2,6-diisopropylphenol) is a widely used intravenous anesthetic, and the effects of propofol on several ion channels have been studied at the whole cell and single-channel levels. However, in general there is no report on the effect of propofol on outward K+ currents in canine colonic myocytes, in which there are two types of outward K+ currents, a large-conductance Ca2+-activated K+ current and a classical delayed rectifier K+ current. We examined the effects of propofol on the two types of outward K+ currents the kinetics involved. METHODS: Experiments were performed on freshly dispersed smooth muscle cells from the circular muscle layer of the proximal canine colon. Outward currents were recorded using the patch clamp technique in the whole cell configuration. RESULTS: The application of propofol (600 nM-600microM) decreased net outward current in a dose-dependent manner. Propofol (6-60microM) also decreased peak delayed rectifier K+ currents. Pretreatment with TEA abolished propofol effects on delayed rectifier K+ currents. However, propofol still decreased delayed rectifier K+ currents in the presence of 4-AP. CONCLUSIONS: These data suggest that propofol decrease net outward K+ currents primarily by inhibiting large-conductance Ca2+-activated K+ currents and 4-AP resistant delayed rectifier K+ currents. These results suggest that propofol action on outward currents may depend on the different blocking mechanisms of the different types of K+ channels. If propofol cannot induce contraction, Ca2+ currents in colonic myocytes warrant further study.
