We present a case of a 19-year-old male with portal vein gas embolism resulting from accidental ingestion of 35% hydrogen peroxide. Hydrogen peroxide is a commonly used germicidal cleansing agent. When it is applied to tissues, catalase causes its rapid molecular decomposition with the release of oxygen bubbles. The patient recovered without sequelae. Hyperbaric oxygenation may be of benefit in patients with respiratory compromise or central nervous system symptoms from gas embolism in hydrogen peroxide ingestion.

Retroperitoneal teratoma is a rare congenital neoplasm derived from three germ layers and generally recognized as a disease of childhood. Those who were not operated on did not fare any better. The mortality from the disease was virtually 100%. Recently, we experienced a case of retroperitoneal teratoma.

Adrenocortical adenomas are relatively rare tumor in retroperitoneum, and most cases are nonfunctioning tumors. Recently, we experienced two cases of functioning Adrenocortical adenomas giving rise to adrenogenital syndrome and Cushing's syndrome.

Pituitary tumor can be accompanied with various pituitary hormone abnormalities. Pituitary tumors can be divided into functioning or nonfunctioning tumors. A functioning pituitary tumor, via the oversecretion of pituitary hormones, causes diverse clinical features. A nonfunctioning pituitary tumor can be accompanied with pituitary dysfunction and this may be due to compression or destruction of normal pituitary tissue, suppression of the pituitary portal system or direct damage to the hypothalamus. Corticotropin-releasing hormone (CRH) deficiency, which is caused by defects in the synthesis or release of CRH, is a cause of secondary adrenocortical insufficiency. The clinical presentations are hypoglycemia, weight loss, anemia, weakness, nausea, vomiting and hyponatremia. Acquired CRH deficiency has also been suggested to occur based on a lack of adrenocorticotropic hormone (ACTH) response to insulin-induced hypoglycemia, but there is a normal ACTH response to exogenous CRH. We experienced a case of a woman with pituitary macroadenoma accompanied with CRH deficiency. We report here on this case with the review of the literature.

BACKGROUND: Recent findings suggest that a coupling between the somatic and sympathetic nervous system is critical not only for the development but also for the maintenance of pain behavioral changes. However, studies on the effect of sympathetic efferent system on sensory receptors in the visceral organ that is more dependent on the autonomic nervous system are lacking. This study examined whether norepinephrine (NE) had an influence on the mechanoreceptors in the feline urinary bladder. METHODS: Ten adult male cats were used and anesthetized with alpha-chloralose and artificially ventilated. A cannula with the pressure transducer was inserted through the urethra to apply mechanical stimuli and monitor the pressure of bladder. A tiny cannula inserted into the bilateral side branches of vesical arteries were used as a route for a NE (10A.M 9:40 01-10-08 bilaterally) injection. Nerve fiber recordings were obtained from the distal stump of the pelvic nerve. RESULTS: After the NE injection, the response of mechanoreceptors (n = 13) to the isotonic pressure stimulus (50 - 60 mmHg) decreased significantly (p < 0.05) in terms of sensitivity (i.e., ratio of nerve activity change to urinary bladder pressure change). The responses to pressure stimuli after an injection of an alpha1 adrenoceptor blocker (terazosin) reversed the effect of NE. The responses of mechanoreceptors to isotonic pressure stimulus were not affected significantly by NE with preinjection of an alpha2 adrenoceptor blocker (yohimbine). CONCLUSIONS: These results suggest that NE may have influence on the sensitivity of mechanoreceptors in the normal feline urinary bladder via an alpha1 adrenoceptor.

BACKGROUND: There are several active tuberculosis (TB) cases in Korean high schools each school year. The risk of transmission in schools is extremely high due to the considerable time spent in closed classrooms. We evaluated the control of latent tuberculosis infection in Korean high schools. METHODS: When a student was identified with active TB, tuberculin skin testing was performed on their classmates and on students in their same school grade. When a student had a positive tuberculin skin tests (TST), they underwent follow-up testing with QuantiFERON-TB Gold In-Tube (QFT). The manufacturer recommended a cut-off of 0.35 IU/mL to determine QFT positivity was applied. RESULTS: A total of 131 pulmonary tuberculosis (TB) patients were included based on the criteria for screening TB contacts in the National Tuberculosis Control Program. Seventy-five (57.2%) students tested smear positive. TST were performed on 7,109 students who were classmates of, or in the same grade as, a TB patient. Of the contacts, 1,231 students (17.3%) were TST positive and they were screened with QFT. Six hundred-sixty-six (55.0%) of the tested students returned a positive QFT result and the rate of positivity was significantly associated with the increasing size of TST indurations (p<0.0001). CONCLUSION: The use of QFT resulted in approximately 45% of TST positive students not being given chemoprophylaxis.

PURPOSE: The purpose of this study is to analyze the clinical features of distal tibia fractures and to evaluate the treatment outcomes of minimally invasive plate osteosynthesis (MIPO). MATERIALS AND METHODS: From January 2004 to December 2009, 84 cases of 81 patients treated with plate fixation for distal tibia fracture were enrolled in this retrospective review. We investigated age, sex, injury mechanism, fracture patterns, and complications, and the clinical features were analyzed. To evaluate the treatment outcomes of MIPO, we divided into two groups. MIPO group consisted of 55 patients were treated with MIPO technique and conventional group consisted of 18 patients were treated with open reduction and internal fixation with conventional anterolateral plating. The results were compared between two groups by assessing bony union time, operation time, amount of blood loss, range of ankle motion, clinical score by American Orthopaedic Foot and Ankle Society (AOFAS) score, and post-operative complications. RESULTS: The mean age of 81 patients with distal tibia fracture was 54.8 years. According to AO classification, A1:2:3 were 16, 20, 16 patients, B1:2:3 were 2, 8, 7, C1:2:3 were 1, 3, 11 patients. According to injury mechanism, slip down injury was patients, traffic accident was 26, fall from height injury was 14 patients respectively. The type A fractures were lower energy trauma and more older patients. The type C fractures were higher energy trauma and younger patients. MIPO group was better than conventional group in operative time, blood loss, bony union time, and ankle joint motion. In complications, MIPO group showed no nonunion and infection, one malunion, one skin necrosis, nine skin irritations, and one screw breakage. Conventional group showed two nonunion, four infections, two skin necrosis, and one metal failure. CONCLUSION: Distal tibial fractures caused by low energy trauma were on the increase. Minimal invasive plate osteosynthesis was shorter bony union time and operation time, less blood loss, and larger ankle motions than conventional open reduction and plate fixation.

Biliary cystadenoma is a rare tumor that arises in the liver or, less frequently, in the extrahepatic ducts. Jaundice in patients with biliary cyst adenoma is not uncomon, but it is very rare that the jaundice is caused by tumor compression of the bile duct. A 43-year-old woman who had a huge biliary cystadenoma occupying the left liver developed deep jaundice. Endoscopic retrograde cholangiopancreatograpy demontrated that this tumor compressed the common hepatic ducts extrinsically which caused the deep jaundice.
