Scanning electron microscopic(SEM) examination of hair is an efficient and definite method for the diagnosis of hair anomaly. The Hair specimen is placed on a stub, gold coated, and directly viewed without prior fixation or treatment for identification. We have analyzed 25 cases of scalp hair and 2 cases of eyebrow that were sampled with the suspicion of hair anomalies at Seoul National University Hospital during the last 7 year period from January 1988 to June 1992. All 27 cases had certain abnormalities of the hair. They consisted of monilethrix(1 case), hair casts(4 cases), pili torti(1 case), uncombable hair syndrome(1 case), trichorrhexis nodosa(5 cases), woolly hair(5 cases) and other anomaly(1 case). Some cases of them were mixed with two or three anomalies in hairs. Their combinations were; hair casts and woolly hair(1 case), hair casts and pili torti and uncombabla hair syndrome(1 case), hair casts and uncombable hair syndrome and trichorrhexis nodosa(1 case), trichorrhexis nodosa and uncombable hair syndrome(3 cases). Most of these defects included brittleness of scales and distortion of the hair shaft.

PURPOSE: The aim of this study was to identify clinical predictive factors for tumor response after preoperative chemoradiotherapy (CRT) in rectal cancer. MATERIALS AND METHODS: The study involved 51 patients who underwent preoperative CRT followed by surgery between January 2005 and February 2012. Radiotherapy was delivered to the whole pelvis at a dose of 45 Gy in 25 fractions, followed by a boost of 5.4 Gy in 3 fractions to the primary tumor with 5 fractions per week. Three different chemotherapy regimens were used (5-fluorouracil and leucovorin, capecitabine, or tegafur/uracil). Tumor responses to preoperative CRT were assessed in terms of tumor downstaging and pathologic complete response (ypCR). Statistical analyses were performed to identify clinical factors associated with pathologic tumor response. RESULTS: Tumor downstaging was observed in 28 patients (54.9%), whereas ypCR was observed in 6 patients (11.8%). Multivariate analysis found that predictors of downstaging was pretreatment relative lymphocyte count (p = 0.023) and that none of clinical factors was significantly associated with ypCR. CONCLUSION: Pretreatment relative lymphocyte count (%) has a significant impact on the pathologic tumor response (tumor downstaging) after preoperative CRT for locally advanced rectal cancer. Enhancement of lymphocyte-mediated immune reactions may improve the effect of preoperative CRT for rectal cancer.

A case of congenital absence of right atriovntricular (A-V) connection of heart is reported. Patient was 81 day old male infant with chief complaints of dyspnea and irritability. Clinical evaluation revealed increased pulmonary vascularity on chest x-ray, absence of right A-V connection, regurgitation of left A-V valve, right-sided ventricular hypoplasia and L-TGA. Clinical assessment of the case was tricupsid atresia with LTGA and mitral regurgitation. Pulmonary artery banlding and artial septectomy was performed. Parenteral alimentation through the femoral veins resulted in obstruction of IVC and subsequent multiorgan failure. The autopsy findings of the heart were corrected transposition of great arteries with associated anomallies of right-sided mitral atresia, Ebstein's malformation of left-sided tricuspid valve, ventricular septal defect, muscular hypertrophy of right-sided left ventricle with luminal obliteration. Long segment of IVC was completely occluded due to occlusive thrombi with fungal infection. Bilateral kidneys were infarcted and azygos vein was markedly engorged. Microscopic examination revealed candidal colonization in the inferior vena cava and septic embolzation in brain.

Nevus comedonicus is an uncommon skin disorder that clinically appears as linear groups of open comedones. A 6-year-old female patient presented with a nevus comedonicus accompanied by an epidermal nevus in her genital area. The histopathologic finding showed an atrophic, cystically dilated hair follicle containing abundant keratinous debris. She was treated with oral antibiotics. We report here on an unusual case of nevus comedonicus that occurred in the genital area.

BACKGROUND: The treatment strategy for biliary pancreatitis varies according to the locations of biliary stones and the severity of the pancreatitis. The role and the timing of Endoscopic Retrogradc Cholangio Pancreatography (ERCP) in biliary pancreatitis have not yet been defined, and recently a laparoscopic cholecystectomy has emerged as a useful means in biliary pancreatitis. METHODS: From December 1986 to June 1997, a total of 66 patients (31 males and 35 females) presented with acute biliary pancreatitis at our institution. The medical records were reviewed to determine the diagnostic tools, the location of the gallstone, the severity of the pancreatitis according to Ranson's prognostic score, the timing of ERCP or surgical intervention, the morbidity, and the mortality of each treatment. RESULTS: Most biliary stones were found in the gallbladder, and Common bile duct (CBD) stones, which could be removed via ERCP or choledocholithotomy, were identified in 10 cases (15%). Most patients (86%) were classified as having a mild attack (Ranson's score< or =2) of acute pancreatitis. There was no statistical significance in the timing of each treatment modality between the mild and the severe pancreatitis groups. CONCLUSIONS: ERCP was a safe and helpful adjunct for managing CBD stones. The laparoscopic cholecystectomy was proved to be a safe and effective measure for managing gallbladder stones in resolving biliary pancreatitis. However, open surgery was still necessary when pancreatitis-related complications occurred.
