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.

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.

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.

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.

Typhoid fever is still endemic in developing countries and the cause of much morbidity and mortality. Complications such as intestinal hemorrhage, intestinal perforation, hepatitis, pyelonephritis, cholecystitis, osteomyelitis are known to occur. The classical approach to management of intestinal hemorrhage due to typhoid ulceration has been conservative. In, however, the event of massive, persistent and life-threatening hemorrhage not responding to conservative measures, early surgical intervention is life-saving. But surgical intervention is difficult due to multiple bleeding sites and friable distal ileum and colon. These two cases are reported in order to draw attention to the usefulness of mesenteric arteriography and the effectiveness of transcatheter embolization therapy in massive intestinal hemorrhage due to typhoid fever.

Percutaneous transhepatic biliary catheterization (PTC) has not only been increasingly used in the localization of benign and malignant lesions, but it is also considered rapid, safe and effective method to establish internal and external drainage for decompression of biliary obstructions. Infections and granulomas at the catheter entry site can occasionally develop, but are easily managed. However, such technique, when used both for obtaining malignant cells for diagnosis and for percutaneous decompression of the biliary tract can exposure the patient at risk for dissemination of the tumor along the catheter tract. This rare complication has been observed in a patient who underwent percutaneous transhepatic biliary drainage (PTBD) for malignant biliary tract obstruction. Although tumor cell seeding along the catheter tract is a very rare complication, we think that PTBD should be avoided when curative resection is planned.

Defective or inadequate pelvic floor function is important etiologic factor for urinary stress incontinence and uterine prolapse. Pelvic floor muscle exercise is the mainstream of the nonoperative treatment for female stress urinary incontinence. Especially Vaginal cones have been known as a simple and practical means of improving both pelvic floor muscle strength and genuine stress incontinence using biofeedback mechanism. Forty adult women suffering from mild and moderate stress incontincnce were instructed to exercise their pelvic muscles using vaginal cones. They retained cones of increasing weight in the vagina by contracting pelvic floor muscles for 15 minutes twice a day for 4 weeks. The comparison of pelvic floor muscle function before and after the exercise were assessed by the frequency of incontinence, vaginal digital palpation, vaginal pressure measurement and speculm lift test. The results were as follows; 1. The frequency of incontinence was significantly reduced after the exercise using vaginal cone (P<0.001). 2. Vaginal digital palpation score (strength of vaginal levator muscle) was significantly increased after the exercise using vaginal cone (P<0.001). 3. The vaginal pressure by perineometer was significantly increased after the exercise using vaginal cones (P<0.001). 4. The vaginal lumen during contraction was significantly narrower after the exercise using vaginal cones (P<0.001). 5. The maximal cone weight which patients could hold over 1 minute was significantly increased after the exercise using vaginal cones (P<0.001).

Most cases of superior vena cava (SVC) syndrome are secondary to malignant disease and subacute in their presentation. However, the exponential increase in use of indwelling central venous catheters and cardiac pacemakers over the last two decades has resulted in more patients with SVC syndrome. Internal jugular vein cannulation has become the preferred approach for temporary hemodialysis catheter placement following the reports of an increased incidence of subclavian vein stenosis due to subclavian vein catheterization. We describe a patient who developed SVC syndrome after internal jugular vein catheterization. The patient had been swollen the left arm intermittently due to left central vein stenosis for 1 year and experienced balloon angioplasty and stent insertion for three times. We diagnosed the SVC syndrome through the both subclavian venography, which revealed complete obstruction of the left brachiocephalic vein with extensive collateral circulation and mild stenosis of the distal right internal jugular vein. Resolution of the clinical SVC sydrome occurred after catheter removal.
