Meckel-Gruber syndrome is a quite rare congenital disorder, characterized by posterior encepalocele, cleft palate and lip, polycystic kidneys, hepatic fibrosis with bile duct proliferation, and postaxial polydactyly and syndactyly. We experienced an autopsy case of M eckel-Gruber syndrome in a second baby of 28 year-old woman. At 26 weeks of gestation, congenital anomaly was detected on ultrasonographic examination and the pregnancy was terminated. Familial history was not noted.

Though trichogenic tumors were classified as trichoblastoma, trichoblastic fibroma, trichogenic trichoblastoma and trichogenic myxoma by Headington(1970), their true classification depends upon the epithelial and mesodermal component as well as evidence of their induction. Because of the rarity of hair germ cell tumors their classification is still controversial. In this report, we describe a case of trichogerminoma which is not included in the above classification. The trichogerminoma was first described by Sau et al. in 1992 and characterized by its morphologic pattern of germinal centers and lymphoid follicle-like structures in the nests of trichoblasts. Herein we reporte a tumor which arose on the skin on the back of a 51-year-old man and presented as a sharply circumscribed mass(4.5x2.0x1.5 cm) involving both the dermal and subcutaneous tissues without any epidermal connection. The tumor had many germinal center-like structures in the basaloid trichoblasts. Lobular cell nests were separated by variable amounts of stroma, but no horn cyst were noted. The germinal center-like cells showed early differentiation of hairs, resembling early hair bulbs. Trichogerminoma is considered to be a type of tumor located between trichoblastoma and trichoblastic fibroma.

To eat unidentified or misidentified mushrooms taken from the wild can be very dangerous. In the vast majority of toxic mushroom ingestions in Korea, the mushroom was incorrectly identified. In general, poisoning of toxic mushrooms can be classified into seven types according to the toxins that they contain; amatoxin, gyromitrin, coprine, muscarine, ibotenic acid-muscimol, psilocybin-psilocin and gastrointestinal irritants. When clinicians care for a patient who ingested a toxic mushroom, it is very important to identify what kind of mushroom may have caused a patient's illness. But, in clinical practice, accurate botanical identification of the mushroom can be very difficult. Therefore, for estimating the caused mushroom and adequate treatment of poisoning, clinicians should know the type and treatment of toxic mushroom poisoning.

Gastrointestinal stromal tumors are notorious for their unpredictable clinical behavior. To assess the cellular proliferating activities, four different methods were used: mitotic count, nucleolar organizer region(AgNOR) staining, immunostaining of proliferating cell nuclear antigen (PCNA) and DNA ploidy were used on 39 cases of gastrointestinal stromal tumors. Additionally, we analysed cellularity, cellular atypism and necrosis. Among 39 cases of gastrointestinal stromal tumors, 11 cases were diagnosed as benign lesions according to clinicopathologic findings. Malignant lesions were arbitrarily classified into low grade(n=ll) and high grade(n=17) on the basis of absence or presence of recurrence, metastasis or tumor-related death during the follow-up period. Numbers of mitosis, AgNORs, PCNA index and DNA ploidy were correlated with grades of tumor and prognosis. Among them, AgNORs counting appeared to be the most useful in predicting prognosis. Numbers of mitosis, PCNA index and DNA ploidy showed varying degrees of overlap among the 3 groups. Among the histological parameters, cellular atypia showed some relationship with the prognosis that others did not reveal.

OBJECTIVE: This study examined the effects on mortality and cell death after biomass charcoal combustion, in which carbon monoxide (CO) emissions were reduced using a biomass combustion improver in mice. METHODS: The biomass (glycerin) charcoal (Biomass CharCoal by Pusan National University, BCCP) was generated in the Power Generation System laboratory, Pusan National University. The effects and molecular mechanisms of biomass charcoal in carbon monoxide poisoning were examined by analyzing the mouse mortality, circulating leukocytes, carboxyhemoglobin (COHb), and expression of the inflammation-related genes, and cleaved capase-3 using enzyme-linked-immunosorbent-assays, real-time polymerase chain reaction, or Western blotting. RESULTS: The mortality rates were lower in the BCCP-exposed mice than in the raw charcoal-exposed mice. The circulating leukocytes were lower in the BCCP-exposed mice than in the raw charcoal-exposed mice. On the other hand, there was no significantly difference in the levels of COHb between both mice. Interestingly, the expression of the apoptosis-related gene, cleaved-capase 3, and the inflammation and tissue necrosis-related gene and receptor for the advanced glycation end products were reduced markedly in the BCCP-exposed mice compared to the raw charcoal-exposed mice. Decreased inflammation and tissue necrotic factors could be molecular mechanisms for the decreased mortality rates after BCCP burning. CONCLUSION: Biomass charcoal (BCCP) reduced the mortality rates and inflammation and tissue necrotic factors by 30%–40%. These results suggest that the biomass charcoal (BCCP) could reduce the incidence of suicide and CO-associated delayed symptoms after charcoal burning. Furthermore, it could extend the time for rescue in suicide attempts using charcoal burning.

PURPOSE: Ingestion of puffer fish can be poisonous due to the presence of potent neurotoxins such as tetrodotoxin (TTX) found in its tissues. There are few clinical reports related to TTX. We performed this study to evaluate the clinical characteristics of TTX poisoning. METHODS: We conducted a retrospective study of the 41 patients diagnosed with TTX poisoning who visited the Seoul Asan medical center from July 2004 and December 2010. A review of patients'electronic medical records and patient telephone interviews were conducted. Diagnosis of TTX poisoning was confirmed by observing the casual link between puffer fish consumption and the development of typical TTX intoxication symptoms. RESULTS: The mean age of the patients included in the study was 46.6 years. The highest incidence of intoxication was observed in patients in their 50s (10 patients). Seasonal distribution of intoxication events included 10 in spring, 7 in summer, 10 in fall, and 14 in winter. In most cases, symptoms occurred within 1 hour of ingestion. A wide range of symptoms were associated with puffer fish ingestion affecting multiple body systems including neuromuscular (27 patients), gastrointestinal (19 patients), and cardiopulmonary/vascular (19 patients). All patients were treated with symptomatic and supportive therapy and recovered completely, without sequelae, within 48 hours. In three cases, ventilator support was required. CONCLUSION: TTX poisoning is not seasonally related, and patients admitted to the emergency room were observed with a wide range of symptoms. Where TTX poisoning is diagnosed, supportive therapy should be performed. Early intubation and ventilation is important, especially is cases of respiratory failure.

Arterial pseudoaneurysm is rare but potentially a catastrophic complication of pancreatitis because it can cause massive gastrointestinal bleeding. Since surgical treatment of arterial pseudoaneurysm has a high mortality, percutaneous angiographic embolization of bleeding artery has recently been advocated as the alternative therapy. Acute hemorrhage into the peritoneal cavity or pseudocyst complicating chronic pancreatitis was frequently reported. However, multiple pseudoaneurysmal hemorrhage without pseudocyst complicating acute pancreatitis are extremely rare. Here, we present a case of multiple pseudoaneurysmal hemorrhage secondary to acute pancreatitis, which were managed successfully by percutaneous angiographic embolization.
