Constrictive pericarditis is caused by fibrosis of the pericardium leading to decrease in ventricular compliance. The diagnosis is often delayed due to nonspecific signs and symptoms. The authors experienced eight cases of constrictive pericarditis detected on chest CT scan while being treated for considerable length of time under the clinical impressions of intrathoracic tumor, tuberculous pleural effusion, liver cirrhosis, etc. Constrictive hemodynamics of these patients were confirmed by echocardiogram and cardiac catheterization. Among them five cases were due to tuberculosis. In four cases with pathologically proven tuberculous granuloma, the pericardium was markedly thickened and intensely enhanced. Associated pericardial effusion (n=3), and mediastinal lymphadenitis (n=3) were present, but pericardial calcifications were not seen. On the other hand, the fibrosis group (n=3) displayed mild pericardial thickening. All the three patients showed pericardial calcifications, mild or absent enhancement of pericardium, but no mediastinal lymphadenitis. The cardiovascular changes such as inferior or superior vena caval distension, left ventricular deformity, interventricular septum angulation, and biatrial enlargements were more severe than those in patients with active granuloma. In patients with constrictive pericarditis with nonspecific signs and symptoms, CT scan is very helpful in making the diagnosis and can give informations about the evolution of the disease.

Primary peritonitis usually refers to a bacterial infection of the peritoneal cavity without a demonstrable intra-abdominal source. Most cases occur in children with ascites resulting from nephrotic syndrome or cirrhosis. Rarely, it may occur in previously healthy children less than 7 years of age, usually a girl. Distinguishing primary peritonitis from appendicitis may be impossible in patients without a history of nephrotic syndrome or cirrhosis. Accordingly, the diagnosis of primary peritonitis is made only at laparotomy. We report one case of primary pneumococcal peritonitis in a 27-month-old female who underwent explorative laparotomy to discover the cause of suspicious intestinal perforation and mechanical ileus. Later, pneumococci were cultured in blood and gram-positive diplococci were isolated from the pus of peritoneal cavity.

Cervical carcinoma is the second leading cause of death from cancer in women worldwide. It is well known that human papillomaviruses (HPVs) is the etiologic agent of cervical neoplasia and cervical cancer. Zinc has been shown to inhibit the growth of malignant cell lines by inducing apoptosis and cell cycle arrest. Recently it was reported that zinc-citrate compound (CIZAR(R)) has a cytotoxic effect on choriocarcinoma cell line and ovarian adenocarcinoma cell line and suppresses its proliferation inducing apoptosis. CIZAR(R) prevents the proliferation by inactivation of m-aconitase activity and induces apoptosis by increasing Bax expression and reducing Bcl-2 expression and inactivation of telomerase. We report one patient of cervical adenocarcinoma with HPV infection, who desires to continue pregnancy, treated by daily topical application of SeLava(R) which contains zinc-citrate compound (CIZAR(R)). We followed up the cytologic, pathologic and coloposcopic changes of healing process.

OBJECTIVE: Ovarian hyperstimulation syndrome (OHSS) is one of the well known complication of conttolled ovarian hyperstimulation. Though there have been numerous protocols for the prevention of OHSS, it has not been completely preventable until now. This study was performed to identify clinical predictors for early and late OHSS. METHODS: A retrospective analysis of all IVF cycles in 1993 up to June 1996 was performed. OHSS was diagnosed using the criteria of Rabau modified by Schenker. All cases of OHSS reported in this study presented with marked ovarian enlargement, ascites, oliguria, hemoconcentration and electrolyte disturbance. Ovarian stimulation was carried out using a combination of gonadotrophin releasing hormone-agonist, follicle-stimulation hormone and human menopausal gonadotrophin. 27 patients has moderate or severe OHSS presenting 3-7 days post-human chorionic gonadotrophin (hCG), and 21 patients had severe OHSS presenting 12-17 days post-hCG. RESULTS: No patient with early OHSS went onto develop late OHSS, and no patient with late OHSS had demonstrated early OHSS. Logistic regression showed that early OHSS was predicted by the number of oocytes retrieved and the estradiol concentration on the day hCG injection (P<0.05). Late OHSS was predicted by the transferred embryos, B-hCG on 14 day after hCG injection (P<0.05). CONCLUSION: Early OHSS was an acute effect of the hCG administered prior to egg retrieval in women with high estradiol and large number of retrieved oocytes. Our analysis of the risk factors for early OHSS indicates that cryopreservation of all embryos will not alter the risk of early OHSS even though it should prevent late OHSS. Late OHSS was induced by the rising serum concentration of hCG produced by the early pregnancy, the number of transferred embryos must be adjusted carefully, since it was associated with multiple gestation.

The safety, tolerability and immunogenicity of an oral cholera vaccine (OCV) was assessed in adult Korean male through an open-label, non-comparative clinical study. Two doses of vaccine with an interval of 2 weeks were given to 20 healthy subjects. A total of 7 adverse events occurred in 6 subjects. However, no clinically significant change was observed in electrocardiograms, vital signs, physical examinations, and clinical laboratory tests. The immunogenicity of OCV was evaluated by serum vibriocidal assay where anti-Vibrio cholerae O1 and O139 antibodies were measured at day 0, 14, and 28 of vaccine administration. The antibody titers ranged from < 2.5-5,120 for V. cholerae O1 Inaba, < 2.5-10,240 for V. cholerae O1 Ogawa and < 2.5-480 for V. cholerae O139. In addition, the fold increase in antibody titers ranged from 1-4,096 for O1 Inaba, 1-8,192 for O1 Ogawa, and 1-384 for O139. The seroconversion rate was 95% and 45% for O1 and O139 antibodies, respectively. Our study clearly shows that administration of two doses of OCV at a 2 week-interval increases an appropriate level of antibody titer in the serum of healthy Korean adult males (Clinical Trial Number, NCT01707537).

BACKGROUND: Neurofibromatosis type 1 (NF1) is one of the most common inherited disorders and is characterized by abnormalities in multiple tissues derived from the neural crest. OBJECTIVES: We analyzed the presence of mutations of NF1 gene in unrelated 56 Korean NF-1 patients. METHODS: Mutations were detected by polymerase chain reaction, single strand conformational polymorphism analysis and direct DNA sequencing. RESULTS: We found five different kinds of mutations in the NF1 gene from 5 out of 56 unrelated Korean NF1 patients. Sequence analysis revealed a nucleotide substitution at codon 1276 of exon 22 (CGA to TGA, R1276X), 4 by insertion at codon 1270 of exon 22 (3809 ins TGGA), a base pair deletion at codon 1398 of exon 24 (4192 del G), 4 by deletion at codon 1638 of exon 28 (4914 del CTCT), and a base pair substitution at codon 1947 of exon 31 (CGA to TGA, R1947X). All of these mutations resulted in premature termination of the mutant alleles. CONCLUSION: Results showed that common consequences of NF1 mutations are introduction of a premature stop codon, and these mutant genes may encode truncated forms of neurofibromin.
