PURPOSE: Recently developed BMS(TM) (Zassi Bowel Management System(TM): Hollister Inc., Illinois, USA) can provide effective nonsurgical fecal diversion without the risks associated with colostomy creation and subsequent closure. Our aim is to evaluate the effectiveness of the BMS in diverting feces from the perianal wide surgical wound in patients with Fournier's gangrene. METHODS: BMS(TM) was applied in five patients (male: 2, median age; 44) with Fournier's gangrene from January 2000 to September 2001. The treatments consist of three times a day wound dressing after wide surgical debridement and intravenous antibiotic therapy. For evacuation of feces, twice daily warm saline irrigation was administered via BMS(TM) or low daily doses of polyethylene glycol solutions were orally taken in. An endoscopic and anorectal manometric study was done to evaluate possible mucosal complications and anorectal functional changes. RESULTS: The average duration of the BMS application was 41 (range, 22~63) days. The result of a manometric study after immediate removal of the BMS(TM) showed a decreased mean resting pressure (range: 22~36 mmHg) and a decreased mean squeezing pressure (range: 32~39 mmHg). After 3 days, the sphincter pressure had improved markedly: mean resting pressures of 38, 45, 60, and 63 mmHg and mean squeezing pressure of 78, 89, 91, and 101 mmHg respectively. Fecal incontience was not noted in any patient. Other possible mucosal complications were not noted. There were no mortalit. CONCLUSIONS: BMS(TM) application in Fournier's gangrene patients after surgery successfully avoids a defunctioning colostomy. Furthermore, no significant complications were noted over a prolonged period up to 63 days.

BACKGROUND: Fine needle aspiration(FNA) is regarded as the best procedure in the diagnosis of thyroid malignancies. However, the rate of false negative and indeterminate results are between 5~10 and 10~30%, respectively. Therefore, a new diagnostic tool to assist FNA is required. Recently, high resolution ultrasonography(US) has become a useful tool in the detection of malignant thyroid nodules. Therefore, the sonographic characteristics differentiating malignant from benign nodules were analyzed, and the usefulness of US in the diagnosis of thyroid malignancy assessed. METHODS: Of the 212 patients that underwent surgery due to a thyroid nodule, at the Daegu Catholic University Hospital between January 2002 and June 2004, and 181 patients(199 nodules) who underwent high resolution US examination before surgery, were included in this study. The characteristics of the sonographic parameters, such as depth/width ratio, shape, margin, structure, sponge sign, calcification and halo, and the homogeneity and echogenicity of the solid component and invasion, were observed. RESULTS: In a univariate analysis of the nonfollicular neoplasms, the depth/width ratio, shape, margin, structure, calcification and halo, and the homogeneity and echogenicity of the solid component were found to be significant parameters. The "sponge sign", a new parameter suggested by us, was found only in benign nodules. In a multiple logistic regression analysis, only the depth/width ratio, shape, presence of calcification and echogenicity of the solid component were significant parameters. According to the results of the multiple logistic regression analysis, the point and estimate of each characteristic of the significant parameters were found, and a formula for calculating a score for the prediction of malignancy computed. At a score of 0.44, the sensitivity and specificity of US were 85.9 and 88.7%, respectively. In a univariate analysis of follicular neop-lasms, the shape, calcification and echogenicity were found to be significant parameters. CONCLUSION: It was conclude that high resolution US is a very useful tool in the differentiation of benign and malignant nodules, especially in nonfollicular neoplasms. It is also suggested that the "sponge sign" might be used as a strong indicator for the confirmation of benign nodules

A 62-year-old male was admitted for evaluation of a mass shadow on chest film. Chest PA showed 7×5cm lobulated homogenous mass in right upper medial area of lung. On chest computed tomography, there was a Barge irregularly lobulated mass with central necrotic low density area in apical segment of right upper lobe. Right upper lobectomy of the lung was performed. Partial adhesion to parietal pleura of posterior mediastinum and severe adhesion to right upper apicoposterior segment was found during the operation Microscopic and ultrastructural studies(including immunocytochemical stains) of the mass revealed malignant fibrous histiocytoma.

A 36-year old woman with Sjogren's syndrome, distal renal tubular acidosis and hypokalemic muscle paralysis is described. The main manifestation was muscle paralysis due to hypokalemia secondary to renal tubular acidosis. Review of English literatures revealed 13 cases of hypokalemic paralysis due to Sjogren's syndrome. The data from those reports have indicated that hypokalemic paralysis was seen more often in patients with primary Sjogren's syndrome than secondary one and that it might precede the classic sicca comple. Hypokalemic paralysis may serve as a clinical marker for more severe renal disease in patients who have primary Sjogren's syndrome and renal tubular acidosis, even though it is a rare manifestation of Sjogren's syndrome.

Carney complex is a multiple neoplasia syndrome, inherited in an autosomal dominant manner, that is characterized by lentigines, cardiac myxoma, and numerous endocrine and other tumors, including primary pigmented nodular adrenocortical disease. Here, we describe a typical case of Carney complex in a 27- year-old female who exhibited spotty skin pigmentation on the lips, oral mucosa, fingers, and toes and several manifestations of Cushing's syndrome due to primary pigmented nodular adrenocortical disease. She also had pituitary adenoma, breast tumor and thyroid nodule. Only a few cases of this disorder have been reported in the Korean literature. All of them, however, had only two components of Carney complex: composed of skin pigmentation and primary pigmented nodular adrenocortical disease. Therefore, the present case seems to be the first true case of Carney complex reported in Korea.

Familial isolated primary hyperparathyroidism(FIPH) is associated with multiple endocrine neoplasia type 1 (MEN1) syndrome, primary hyperparathyroidism accompanied by jaw-tumor syndrome, and familial hypocalciuric hypercalcemia. FIPH may be an early stage of MEN1 or an allelic variant of MEN1. Thymic carcinoid tumor is a rare tumor in MEN1 syndrome. Here, the authors report the case of a 40-year-old man diagnosed with recurrent thymic carcinoid tumor and FIPH. Both the patient and his elder sister had been previously diagnosed to have FIPH with a novel frameshift mutation in the MEN1 gene. Initially, the patient underwent thymectomy because of an incidental finding of a mediastinal mass in his chest X-ray, and had remained asymptomatic over the following 4 years. Pancreas computed tomography conducted to evaluate MEN1 syndrome revealed anterior and middle mediastinal masses, and resultantly, massive mass excision was performed. Histological findings disclosed atypical carcinoids with infiltrative margins. In view of the thymic carcinoid tumor relapse that occurred in this patient, the authors recommend that regular pancreas and pituitary imaging studies be conducted for FIPH associated with a MEN1 gene mutation.

BACKGROUND: In patients with severe chronic lung diseases even a small pneumothorax can result in life-threatening respiratory distress. It is important to treat the attack by chest tube drainage until the lung expands. Pneumothorax with a persistent air leak that does not resolve under prolonged tube thoracostomy suction is usually treated by open operation to excise or oversew a bulla or cluster of blebs to stop the air leak. Pleurodesis by the instillation of chemical agents is used for the patient who has persistent air leak and is not good candidate for surgical treatment. When the primary trial of pleurodesis with common agent fails, it is uncertain which agent should be used f or stopping the air leak by pleurodesis. It is well known tbat inappropriate drainage of hemothorax results in severe pleural adhesion and thickening. Based on this idea, some reports described a successful treatment with autologous blood instillation for pneumothorax patients with or without residual pleural space. We tried pleurodesis with autologous blood for pneumothorax with persistent air leak and then we evaluated the efficacy and safety. METHODS: Fifteen patients who had persistent air leak in the pneumothorax complicated from the severe chronic lung disease were enrolled. They were not good candidates for surgical treatment and doxycycline pleurodesis failed to stop up their air leaks. We used a mixture of autologous blood and 50% dextrose for pleurodesis. Effect and complications were assessed by clinical outcome, chest radiography and pulmonary function tests. RESULTS: The mean duration of air leak was 18.4 :1:6.16 days before ABP (autologous blood and dextrose pleurodesis) and 5.2 ± 1.68 days after ABP, The mean severity of pain was 2.3 ± 0.70 for DP(doxycycline pleurodesis) and 1.7 ± 0.59 for ABDP (p<0.05). There was no other complication except mild fever. Pleural adhesion grade was a mean of 0.6 ± 0.63. The mean dyspnea scale was 1.7 ± 0.46 before pneumothrax and 2.0 ± 0.59 after ABDP (p>0.05). The mean FEV1 was 1.47 ± 1.01 before pneumothorax and 1.44 ± 1.00 after ABDP (p>0.05). Exɡpt in 1 patient, 14 patients had no recurrent pneumothorax. CONCLUSION: Autologous blood pleurodesis (ABP) was successful for treatment of persistent air leak in the pneumothorax. It was easy and inexpensive and involved less pain than doxycycline pleurodesis. It did not cause complications and severe pleural adhesion. We report that ABP can be considered as a useful treatment for persistent air leak in the pneumothorax complicated from the severe chronic lung disease.

BACKGROUND: Thyroid cancer is a common disease and its prevalence is increasing. Recent reports have shown that an elevated thyrotropin (thyroid stimulating hormone, TSH) level is associated with thyroid cancer risk. However, the association between TSH level and thyroid cancer risk is not yet known for euthyroid patients diagnosed with papillary thyroid microcarcinoma (PTMC). METHODS: Our study included 425 patients who underwent thyroid surgery and were diagnosed with PTMC between 2008 and 2009. Control group patients were diagnosed with benign nodules < or = 1 cm in size by US-guided fine needle aspiration. Nodules with one or more suspected malignant-ultrasonographic feature(s) were excluded from this study. Patients who were not euthyroid or who took thyroid medication were also excluded. RESULTS: The mean age of all patients was 48.5 +/- 11.0 years and 88.8% were women. The mean age of those with PTMC was significantly lower than that of the control group. The mean TSH level was 1.78 +/- 0.93 mIU/L, and the mean free T4 level was 15.96 +/- 2.32 pmol/L. There was no difference in TSH level between the PTMC and control groups (1.77 +/- 0.93 mIU/L vs. 1.79 +/- 0.91 mIU/L, P = 0.829). After adjusting for age, TSH level was not correlated with tumor size (r = 0.02, P = 0.678) in the PTMC group. Moreover, the TSH level did not differ between patients with stage I and stage III-IV carcinoma (stage I, 1.77 +/- 0.95 mIU/L; stage III-IV, 1.79 +/- 0.87 mIU/L; P = 0.856). CONCLUSION: TSH levels are not elevated in euthyroid PTMC patients. Thus, further evaluation is needed before serum TSH can be used as a tumor marker for small nodules < or = 1 cm in size in euthyroid patients.
