Urachal anomalies are very rare. The umbilicus and the structures which lead to its formation rarely cause trouble except in patients with an error. Embryologically, the urachus represents the vestigial remnant of the allantois which, in the fetus, communicates with the cloaca. The patent urachus results from failure of luminal closure of the urachus Herein a case of congenital patent urachus reported with a brief review of literatures.

OBJECTIVE: Idiopathic thrombocytopenic purpura (ITP) frequently occurs in young women. Consequently, clinicians often give medical treatment to pregnant women who are diagnosed with ITP. This study might help to make a clinical guidelines for obstetrical ITP patients and their infants. METHODS: We retrospectively investigated the medical charts of 19 cases of deliveries and 22 neonates which from mothers with the diagnosis of ITP during pregnancy from March 1998 to March 2007. RESULT: Corticosteroid treatment was administrated in 13 cases, high-dose immunoglobulin therapy in 3 cases, and concentrated platelet transfusion in 17 cases during their antenatal care. Ten (45%) vaginal deliveries and twelve (55%) cesarean sections were performed. There were no obstetrical complications associated with their ITP and only four infants with platelet counts below the 150,000/micronLiter were reported after birth. However there were not any signs and symptoms of neonatal complications resulting from their maternal ITP. CONCLUSION : Our results demonstrate that mothers with ITP can successfully deliver healthy infants in most case. Although maternal and fetal bleeding may occur, such a fatal complication is uncommon.

Primary biliary cirrhosis (PBC) is a chronic progressive disease, more often affecting women, characterised by progressive destruction of the small intrahepatic bile ducts with portal inflammation leading to fibrosis and cirrhosis. There is a close association between PBC and antibodies to antimitochondrial antibodies (AMA). The pathogenesis of PBC remains uncertain. The disease has been considered as an example of autoimmunity. Estimates of disease prevalence vary between 20 and 240 cases per milion per year. PBC is a extremely rare liver disease in Asia. There is no definitive drug treatment, liver transplantation is indicated for patients with intractable symptoms and for end-stage disease. The authors have experienced a case of PBC in 66 year-old female who suffered from lethargy, pruritus and dry mouth since 2 years ago. We report a case of PBC with a review of literatures.

BACKGROUND: Recently, the prevalence of diabetes mellitus in elderly people is increasing in Korea because of an increase in longevity. With advancing age, also a greater proportion of end-stage renal disease (ESRD) patients with complex medical co-morbidity contributes to the higher mortality seen in patients receiving dialysis. Diabetic nephropathy has become the most important cause of ESRD worldwide. More intensive therapeutic manipulation is needed to prevent the progression of diabetic nephropathy, but there are few studies about this subject in type 2 diabetes. The aim of this study is to predict renal outcomes of elderly people with type 2 diabetes and investigate risk factors related with the deterioration of renal function and the development of ESRD. METHODS: Study subjects were 67 elderly patients (over 65 years old) with type 2 diabetes. We retrospectively analyzed risk factors for the end points of doubling of serum creatinine or the development of ESRD (dialysis or transplantation). RESULTS: 17 patients (26.4%) reached the end points during the follow-up period. 16 patients of 43 patients with decreased renal function reached the end points and only one of 24 patients with preserved renal function reached the end points. A univariate analysis revealed significant correlations between renal outcomes and duration of diabetes, anemia, hypoalbuminemia, BUN, baseline serum creatinine, GFR, serum calcium, phosphorus, uric acid levels and the degree of proteinuria. In our multivariate analysis, proteinuria and baseline serum creatinine level were significantly independent risk factors. The risk of doubling of serum creatinine or development of ESRD among patients with baseline urinary protein excretion rate >or=1g/24h was six times higher compared with the risk among those with urinary protein excretion rate <1g/24h. CONCLUSION: Proteinuria and the degree of baseline kidney dysfunction are significant risk factors that contribute to the deterioration of renal function and the development of ESRD in elderly patients with type 2 diabetes. Proteinuria is the most powerful independent predictor of renal outcomes.

Although growth associated protein-43 (GAP-43) is known to play a significant role in the regulation of axonal growth and the formation of new neuronal connections in the hippocampus, there is only a few studies on the effects of acute stress on GAP-43 mRNA expression in the hippocampus. Moreover, the effects of repeated citalopram treatment on chronic mild stress (CMS)-induced changes in GAP-43 mRNA expression in the hippocampus have not been explored before. To explore this question, male rats were exposed to acute immobilization stress or CMS. Also, citalopram was given prior to stress everyday during CMS procedures. Acute immobilization stress significantly increased GAP-43 mRNA expression in all subfields of the hippocampus, while CMS significantly decreased GAP-43 mRNA expression in the dentate granule cell layer (GCL). Repeated citalopram treatment decreased GAP-43 mRNA expression in the GCL compared with unstressed controls, but this decrease was not further potentiated by CMS exposure. Similar decreases in GAP-43 mRNA expression were observed in CA1, CA3 and CA4 areas of the hippocampus only after repeated citalopram treatment in CMS-exposed rats. This result indicates that GAP-43 mRNA expression in the hippocampus may differently respond to acute and chronic stress, and that repeated citalopram treatment does not change CMS-induced decreases in GAP-43 mRNA expression in the GCL.

New-born cells continue to proliferate and survive to become mature granule cells in adult rat hippocampus. Although this process, known as neurogenesis, is inhibited by acute stress, it is not clear whether chronic stress affects neurogenesis. To determine whether chronic mild stress (CMS) influences neurogenesis in the adult rat hippocampus, male Sprague-Dawley rats were exposed to CMS and administered bromodeoxyuridine (BrdU) before or after CMS to observe the survival/differentiation or proliferation of new-born cells, respectively. In addition, we measured brain-derived neurotrophic factor (BDNF) mRNA in the granule cell layer (GCL) of the hippocampus, because BDNF is known to play an important role in the survival of new-born cells. CMS significantly decreased the survival of newborn cells in the GCL, but did not influence the proliferation or differentiation of new-born cells. CMS did not affect the proliferation and survival of new-born cells in the hilus. In addition, CMS did not change BDNF mRNA levels in the GCL. These results demonstrate that CMS reduces the survival of new-born cells but not of their proliferation, suggesting that repeated mild stress could influence a part of neurogenesis, but not the whole part of neurogenesis. These results raise the possibility that the survival of new-born cells may be suppressed in the presence of normal BDNF mRNA levels in GCL.

Recent studies suggest that alterations in glutamate receptor subunit levels in mesocorticolimbic dopamine areas could account for neural adaptations in response to psychostimulant drugs. Although many drugs of abuse induce changes in ionotropic glutamate receptor subunits in mesocorticolimbic dopamine areas, the changes of ionotropic glutamate receptor subunits by repeated nicotine treatment in these areas are not known. To answer this question, we injected male Sprague-Dawley rats twice daily with nicotine (0.4 mg/kg) or saline (1 ml/kg) for 10 days. The immunoreactivity of NR1, GluR1, and GluR2 glutamate receptor subunits was examined 16~18 h after the last injection of saline or nicotine. Repeated nicotine treatment significantly increased NR1 levels in the ventral tegmental area (VTA). In addition, repeated nicotine treatment showed a tendency towards an increase in GluR1 levels in the VTA as well as in striatum. However, there was no significant change in glutamate receptor subunits in other areas including nucleus accumbens (NAc). These results demonstrate that repeated nicotine treatment increases NR1 levels in VTA similarly to other drugs of abuse, suggesting that elevated glutamate receptor subunits in the VTA, but not NAc may be involved in the excitation of mesocorticolimbic dopamine neurons by nicotine.

PURPOSE: Considering that nutritional state correlates to immunity, we performed this study to evaluate the correlation by assessing the numerical changes of the levels of serum albumin and lymphocyte subsets. MATERIALS AND METHODS: The study was performed on patients who were diagnosed as having gastric cancer and who underwent curative surgery from August 1998 to August 2004 in the Gyeongsang National University Hospital and whose peripheral blood lymphocyte subsets were tested prior to surgery. The study population was a total of 150 cases. RESULTS: The change in the lymphocyte subsets in relation to the change in the level of serum albumin in all patients with gastric cancer was determined, and was compared to disease stages. When patients were classified by using the level of serum albumin with 3.2 mg/dl as the cut-off point (low group: serum albumin <3.2 mg/dl, normal group = serum albumin >or=3.2 mg/dl), the number of peripheral blood lymphocytes, CD3+ cells, CD4+ cells, CD8+ cells, and CD16+56 cells were, significantly lower in the group with the level of serum albumin below 3.2 mg/dl (low group) than it was in the group with a serum albumin level above 3.2 mg/dl (normal group) (P<0.05). In stage I (n=59), CD16+56 cells were significantly lower in the low group. In stage II (n=29), the number of CD16+56 cells was lower and the ratio of CD4+/CD8+ was higher in the low group than in the normal group significantly. In stage IV (n=33), except for CD19+ cells, the number of all lymphocyte subsets was significantly lower and the ratio of CD4+/CD8+ was significantly higher in the low group. CONCLUSION: The group with a low level of serum albumin had a low absolute number of lymphocyte subsets. Based on this, we reconfirmed that the nutritional state is closely related with the immune state in patients with gastric cancer.

Pneumatosis cystoides intestinalis is a relatively rare condition, characterized by multiple gas-filled cysts of varying size in the wall of gastrointestinal tract. Although the etiology of pneumatosis intestinalis remains uncertain, the possibility that both the gas-forming bacteria and mechanical theories develop pneumocysts has recently been advocated. We experienced a case of pneumotosis cystoides intestinalis found by colonoscopy in a 31-year old woman with intermittent abdominal pain.
