BACKGROUND : Anomalous pancreaticobiliary ductal union (APBDU) is a congenital defect defined as a union of the pancreatic and the biliary ducts located outside the duodenal wall. Accordingly, this anomalous connection between the choledochus and the pancreatic duct is considered to be a factor in the development of biliary tract diseases such as choledochal cysts, pancreatitis, cholangitis, gallbladder cancer, and bile duct cancer. Our purpose is to analyze combined disease, especially biliary neoplasm, and to evaluate biliary tract microscopic changes in the biliary tract. METHODS : To study the clinical characteristics of APBDU, we reviewed 21 APBDU cases which were treated from June 1994 to January 1998. We studied the associated diseases, the surgical treatment, histological findings and the PCNA expression. We also analyzed the gallbladder epithelium in 10 control patients without APBDU. RESULTS : Among the 21 cases, 12 cases were accompanied by a choledochal cyst. A gallbladder carci noma occurred in 5 cases. Of the 13 operations, 4 involved a cholecystectomy only, and 9 involved a cholecystectomy, bile duct resection and hepaticojejunostomy. The histologic findings were reviewed in 13 cases. Bile duct metaplasia was found in 8 of the 9 cases with a bile duct resection, and gallbladder metaplasia was found in 8 of the 12 cases whereas metaplasia was detected in 1 of the 10 control patients. The PCNA expression was significantly high in APBDU group. CONCLUSIONS : The patients with APBDU showed a high incidence of gallbladder carcinoma and meta plasia in the epithelium of the gallbladder and the bile duct. This metaplasia in the gallbladder and the bile duct was thought to be related to the cancerous change.

Tinnitus-the perception of sound in the absence of an actual external sound-represents a symptom of an underlying condition rather than a single disease. Several theories have been proposed to explain the mechanisms underlying tinnitus. Tinnitus generators are theoretically located in the auditory pathway, and such generators and various mechanisms occurring in the peripheral auditory system have been explained in terms of spontaneous otoacoustic emissions, edge theory, and discordant theory. Those present in the central auditory system have been explained in terms of the dorsal cochlear nucleus, the auditory plasticity theory, the crosstalk theory, the somatosensory system, and the limbic and autonomic nervous systems. Treatments for tinnitus include pharmacotherapy, cognitive and behavioral therapy, sound therapy, music therapy, tinnitus retraining therapy, massage and stretching, and electrical suppression. This paper reviews the characteristics, causes, mechanisms, and treatments of tinnitus.

Patients undergoing maintenance dialysis show an increased susceptibility to tuberculosis because host immunity is decreased secondary to malnutrition, impaired cellular immunity, acidosis and etc. Extrapulmonary tuberculosis is more prevalent in patients with end stage renal disease than in normal subjects. Among the extrapulmonary tuberculosis in patients receiving hemodialysis, the diagnosis of tuberculous spondylitis is difficult because the symptoms are non specific and attributable to uremia, and the appearance of plain radiographs is often normal during the early phase of the disease. We experienced a case of tuberculous spondylitis in a hemodialysis patient. A 55 years old female admitted with fever, weight loss and back pain. Conventional radiograph of T-spine showed no definite abnormal finding. However, chest CT revealed heterogeneously enhancing soft tissue around the T8 vertebral body and T-spine MRI showed compatible finding to tuberculous spondylitis. She received radical excision of involved vertebra and confirmed tuberculous spondylitis with histologic finding from a surgical specimen. Following the administration of anti-tuberculosis medication(isoniazid, rifampin, pyraziamide, ethambutol) and radical excision, patient's symptom and sign were improved. The patient is maintaining dialysis with anti-tuberculosis medication for 5 months.

Propofol (2,6-diisopropylphenol) is an ultrashort-acting sedative agent with sedative and amnestic effects that is used not only for anesthesia but also for sedation during minor outpatient procedures and endoscopic examinations. Rare cases of anaphylaxis following propofol administration have been reported in the medical literature. Documentation of anaphylaxis is often lacking because the cause and effect relationship is often hard to prove. Only a minority of patients get referred for allergy testing to confirm the offending drug. Here we report a 74-year-old woman who had an anaphylactic reaction with severe oropharyngeal edema and bronchospasm for a few minutes after receiving propofol during endoscopic examination. An allergy skin test was positive for both propofol and soybean. Soybean in the intralipid is one component of propofol, and we concluded that this anaphylaxis was caused by soybean.

BACKGROUND: The radial forearm flap is a versatile, widely used flap. However, the possibility of donor site complications has led to concern over its use. Some surgeons prefer using other flaps whose donor sites can be closed primarily with less morbidity, including avoiding unpleasant scarring. However, in our experience, donor site stability of the radial forearm flap can be reliably achieved by using well-implemented specific procedures. Here, we present a collection of donor site cases of the radial forearm flap and investigate factors that affect the aesthetic results as the basis for a reference for selecting a radial forearm flap. METHODS: In this retrospective study, we reviewed 171 cases in which a radial forearm flap was used for free tissue transfer after resecting head and neck cancer. We focused on donor site morbidity rates. Each operation involved a detailed procedure designed to minimize donor site morbidity. Moreover, statistical investigations were conducted for 22 cases to determine factors affecting the scar appearance. RESULTS: Only one case developed total skin graft necrosis as a major complication. Scar-related aesthetic results were acceptable, and the body-mass index, body weight, diabetes, and cardiac problems were significant factors related to the appearance of scars. CONCLUSIONS: Performing the radial forearm flap using a well-implemented detailed technique helps achieve acceptable donor site morbidity results. The aesthetic results were more promising for patients without excess body weight, diabetes, or cardiac problems. Therefore, anxiety about donor site morbidity should not be a reason to avoid selecting the radial forearm flap in suitable patients.

Infective endocarditis is a dreaded complication in dialysis or kidney transplantation patients, with high morbidity and mortality. Despite the improved early survival of the transplanted kidney with new immunosuppressive agents, the number of patients returning to dialysis after a failed renal allograft is increasing. There is no consensus on the optimal management of immunosuppression in patients with a failed allograft. Continued immunosuppression is associated with infection, and the rapid discontinuation of immunosuppression may lead to acute rejection. Therefore, it is important to taper the immunosuppression properly in patients with a failed renal allograft. We report on a hemodialysis patient with a failed renal allograft who had a cerebral infarction following infective endocarditis. The patient was treated successfully with antibiotics and valve replacement.

OBJECTIVES: Peptic ulcer is the major condition that affect numerous individuals every year. In 1983, Warren and Marshall presented the evidence that H. pylori was associated with gastritis and peptic ulcer. Thereafter, K. pylori infection is thought to be a important factor in the pathogenesis of gastric and duodenal ulcer. In western studies, about 58% to 100% of patients with peptic ulcer disease were infected with H. pylori. But in Korea, there is no study about the prevalence of H. pylori infection in peptic ulcer disease despite of its high prevalence and importance. The aim of this study was to investigate the prevalence of H. pylori infection in case of gastric and duodenal ulcer disease in Korea. METHODS: We surveyed the prevalence of H. pylori infection of 1031 patients, who were diagnosed as gastric or duodenal ulcer by gastrofiberoscopy. H. pylori infection was evaluated with Rapid Urease Test(CLO test) and/or histology by Wright-Giemsa staining. RESULTS: 1) Peptic ulcer was more frequently developed in males than females, as the frequency of peptic ulcer was 77% in males, and 23% in females. But in view of the prevalence of H. pylori infection, there was no significant difference between males and females, 73% in males and 71% in females. 2) Gastric ulcer was most common in sixth decade(29.8%), but the prevalence of H. pylori infection was peak in fourth(76%), and fifth decade (73%). 3) Duodenal ulcer was most common in fourth decade(26.3%), but the prevalence of H. pylori infection was peak in teenagers(93%) and third decade(87%). 4) The patients who had both gastric ulcer and duodenal ulcer concurrently were most common in sixth decade(27.9%), but the prevalence of H, pylori infection was peak in third decade(100%). CONCLUSION: We concluded that the majority of peptic ulcer patients in Korea had H. pylori infection. Particularly, young aged patients had higher H. pylori infection rate than old aged.

Hypovolemia and relative polycythemia is not an uncommon presentation in a child with nephrotic syndrome, but it is seldom mentioned in an adult. We experienced a case of hypovolemic shock and erythrocytosis in a patient with minimal change disease. Hypovolemia and polycythemia was corrected only after infusing isotonic fluid with albumin for 3 days. Hypovolemic shock is attributable to some of the following factors; suddenly decreased capillary oncotic pressure due to massive proteinuria, interstitial edema with tubular collapse, redistribution of renal blood flow, decreased glomerular filtration rate, and use of diuretics without albumin. In summary, 1) Relative polycythemia may occur as a result of hypovolemia in a patient with nephrotic syndrome but can be easily corrected by isotonic fluid and albumin. 2) An early detection of hypovolemia can be made by the measurement of central venous pressure, echocardiography, and the assessement of FeNa, U[k]/(U[Na]+U[K]). 3) Diuretics without albumin may result in transient developement of shock in patients with profound volume depletion.
