This series represents 128 cases of acute gonococcal urethritis treated with doxycycline at the Seoul Red Cross Hospital from the 1st. May to.5th, Oct., 1969. Results of this treatment were divided in three groups: Group I ; Single dose of doxycycline, 300 mg. was administered for this group. 36 cases fall into this category. Cure rate for this group was 36%. Group II; Doxycycline, 200mg. was given on the 1st treatment day and daily dose of 100 mg. for 4 ensuing days. 42 cases were included to this group. Cure rate was 72%. Group III Daily dose of 200 mg. was administered for the remainders, 50 cases for 5 consecutive days. Cure rate was 91%. It was concluded that 200 mg. of doxycycline daily for 5 days dose regime can be recommended for the treatment of acute gonococcal urethritis, especially in cases allergic to penicillin or in which penicillin treatment fails. No anaphylactic shock or some other undesirable side reaction in administering this drug was experienced.

The alterations in the localization of keratinocyte membrane glycoconjugates in allergic contact dermatitis were investigated in guinea pig skin treated with topical application of 2.4-dinitro-chlorobenzene. We employed the avidin-biotin complex(ABC) method for the detection of localization of 10 commercially available lectins labelled with biotin: Con-A, SBA, WGA, DBA, UEA-1, RCA-1, PNA, HP, MPA, and ECA. Staining with WGA showed a remarkably decreased intensity in basal and spinous layers of the allergic skin in comparison to those of the control skin, suggesting loss of terminal sialic acids in cell membrane glycoconjugates. The other lectins showed no remarkable difference in the staining patterns between the normal and the allergic ski. The results suggest that epidermal cell membrane glycoconjugates undergoes selective perturbations in acute allergic contact dermatitis, and that the keratinocytes might be an active part of the cutaneous immune system.

BACKGROUND/AIMS: The emergence of lamivudine-resistant mutant hepatitis B virus (HBV), with aminoacid substitution in the YMDD motif of DNA polymerase, has been reported in the long-term lamivudine use group. However there is no report about the emergence of mutant viruses during the short-term lamivudine therapy. The objective of this study was to investigate the emergence of YMDD mutant HBV during short-term lamivudine therapy. METHODS: We evaluated twenty-eight chronic hepatitis B patients who were HBeAg and HBV DNA positive and treated with lamivudine 100mg p.o. daily for 12 weeks. First, we investigated the emergence of YMDD mutants by nested polymerase chain reaction (PCR) method developed by Chayama et al in 19 patients who lost HBV DNA during lamivudine therapy but showed HBV DNA re-emergence 2 weeks after the end of therapy. Second, DNA subcloning and sequencing of HBV DNA polymerase including YMDD motif was undertaken in one patient's serial blood samples at 0, 8, 12 weeks to confirm the results of nested PCR. RESULTS: YMDD motif mutation was detected in 17(90%) out of 19 patients at the end of therapy and the type of mutations were YIDD only. At the end of therapy, mutant was predominant in 5 patients, both mutant and wild type were similar in proportion in 3 patients, and wild type was predominant in 9 patients. When we carried out nested PCR serially with samples of 0, 2, 4, 8, 12, 14 weeks after initiation of therapy in 5 patients who were mutant predominant at 12 weeks, YIDD mutant began to be detected from 2 weeks in 4 patients and from 4 weeks in one patient. However, rapid turnover from mutant to wild type happened after the end of therapy, so only wild type was detected in 3 patients and wild type became predominant in 2 patients at 2 weeks after the end of therapy. All the sequencing results of serial blood samples in one patient were consistent with nested PCR data. CONCLUSIONS: The presence of YMDD motif HBV polymerase mutant may be possible before administration of lamivudine in Korean chronic hepatitis B patients. Nested PCR assay would be an useful method to detect YMDD mutant.

5.Alcohol Abuse Related Medical Complications and Treatment.
Journal of the Korean Medical Association 2006;49(2):114-127
Alcohol abuse is related to a wide variety of medical complications including liver diseases, pancreatitis, cardiovascular diseases, immunological abnormalities, malignant neoplasms, endocrine disturbances, and kidney problems. The liver is the organ most severely affected by alcoholism. Alcoholic liver disease (ALD) remains a major cause of morbidity and mortality in Korea. The mainstay of therapy for alcohol-related medical problems is cessation of drinking. This article summarizes alcohol-related medical complications and treatment with focus on alcoholic liver injury.

Fabry's disease is a rare hereditary metabolic disease caused by alpha-galactosidase deficiency, resulting in abnormal accumulation of galactosyl galactosyl galactosyl ceramide (ceramide trihexoside) in various organs. Articles in English reported approximately one hundred cases but only two cases in Korea. Recently the authors experienced a case of Fabry's disease of a male patient and studied the electronmicroscopy on skin biopsied tissue and enzyme assay of alpha -galactosidase activity in his peripheral blood leukocytes. The male patient was a 21-year-old soldier who suffered from anhidrosis with heat intolerance and generalized telangietatic papules (Angiokeratoma corporis diffusum) since childhood. Other clinical findings were ocular change, paroxysmal pain of lower extremities and proteinuria with oval fat bodies on urinalysis. The ultrastructural study of skin demonstrated abnormal lysosomal deposits of finger-prints or "zebra" body configuration in the endothelial cells, pericytes, perineural cells and intercalated ductal epithelium of sweat glands. Enzyme activity of alpha-galactosidase was markedly decreased in the peripheral blood leukocytes comparing to the normal control, which was conclusive to make a diagnosis of Fabry's disease.

Solid and papillary epithelial neoplasm of the pancreas(SPENP) is an uncommon low grade malignant tumor histologically distinct from the usual ductal adenocarcinoma and amenable to cure by surgical excision. The main features of SPENP are a peculiar morphology, favorable prognosis, and prediction for women 10 and 40 years of age. In men, the occurrence of SPENP seems to be exceedingly rare. The tumor is usually large at the time of presentation, and surgical excision is the treatment of choice. Gross pathologic examination revealed apparent encapsulation, cystic degeneration, and hemorrhagic necrosis. Microscopically, the tumor was characterized by distinctive solid and papillary patterns. This benign or low-grade malignant epithelial tumor is composed of monomorphous cells variably expressing epithelial, mesenchymal, and endocrine markers. The tumor is known to have good prognosis; although local invasion and infiltration of the capsule may occur. Despite growing recognition of this tumor, its histogenesis remains a matter of controversy i.e. pancreatic ductal cell origin, acinar cell origin, pluripotential cell origin. A 44-year-old male presented with an one-year history of postprandial abdominal pain. Following abdominal ultrasonography, computed axial tomography and angiography, a SPENP suspected. The patient underwent exploratory laparotomy. The tumor was located in the head of pancreas. And thus the patient underwent a pylorus-preserving pancreaticoduodenectomy. His postoperative course was uneventful, and he remains well.

Alagille syndrome (AGS) is a complex multisystem disorder that involves mainly the liver, heart, eyes, face, and skeleton. The main associated clinical features are chronic cholestasis due to a paucity of intrahepatic bile ducts, congenital heart disease primarily affecting pulmonary arteries, vertebral abnormalities, ocular embryotoxon, and peculiar facies. The manifestations generally become evident at a pediatric age. AGS is caused by defects in the Notch signaling pathway due to mutations in JAG1 or NOTCH2. It is inherited in an autosomal dominant pattern with a high degree of penetrance, but variable expressivity results in a wide range of clinical features. Here we report on a 31-year-old male patient who presented with elevated serum alkaline phosphatase and gamma-glutamyl transpeptidase, and was diagnosed with AGS associated with the JAG1 mutation after a comprehensive workup.
