A case of cavernous angioma of the cerebellar vermis is described. Cevernous angioma is rare vascular malformation of the central nervous system and the cerebellar vermis is very unusual site. Exact preoperative diagnosis of this lesion is difficult because cavernous angioma is angiographically silent and generally accepted to be very rare. The relevant literature is reviewed.

Isolated adrenocorticotropic hormone (ACTH) deficiency is an uncommon disorder for which the pathogenetic mechanism has not yet been identified. It has been reported that isolated ACTH deficiency (ICD) may be accompanied by deficiencies in other pituitary hormones; impaired growth hormone (GH) secretion was noted in 20 to 30% of ICD patients. Here, we describe a female patient with isolated ACTH deficiency accompanied by empty sella syndrome presenting as hypoglycemia, which was confirmed via various endocrine tests and magnetic resonance imaging (MRI) of the sella turcica. The patient's symptoms improved rapidly with prednisolone therapy and, during follow-up, her previously impaired GH response to provocative stimuli and high TSH levels were corrected by glucocorticoid replacement alone. However, treatment failed to normalize plasma IGF-1 levels, suggesting that physiological cortisol levels are necessary for a normal plasma GH response to provocative stimuli.

Myasthenia gravis and autoimmune thyroid disorders often overlap. It is known that hyperthyroidism occurs in 2~17.5% of patients with myasthenia gravis. Thyrotoxicosis may influence the clinical course of myasthenia gravis. Overlapping clinical features may cause diagnostic confusion when Graves' disease and myasthenia gravis co-exist. Thus, various tests may be needed to distinguish these two diseases. It is clinically important to screen patients with myasthenia gravis for the co-existence of autoimmune thyroid disorders and vice versa. We cared for a patient with Graves' disease associated with ocular myasthenia gravis who presented with fluctuating double vision and ptosis. Ocular myasthenia gravis was diagnosed by electrophysiologic study and presence of acetylcholine receptor antibody. The patient had a favorable clinical and laboratory response to treatment with an anticholinesterase (pyridostigmine) and an antithyroid drug (propylthiouracil), and he had minimal symptoms at the 9-month follow-up examination.

We report a case of advanced gastric cancer with Virchow's node and lung metastasis that responded remarkably to preoperative chemotherapy. A 47-year-old female patient was diagnosed as having incurable advanced gastric cancer with Virchow's node and multiple lung metastasis. Preoperative chemotherapy with Taxotere, CDDP and 5FU was carried out. After four courses of the regimen, the Virchow's node and the lung metastasis had disappeared, and a marked reduction of the gastric lesion was observed on the CT scan. Consequently, the patient underwent a total gastrectomy with D2 lymph node dissection. On histopathological examination, cancer cells were found to have infiltrated up to the muscle layer of the gastric wall, and 42 out of 60 resected lymph nodes were found to be metastatic. The patient received another two courses of chemotherapy after the operation

Duplications of the alimentary tract are relatively rare congenital malformations usually present during infancy or young childhood. They can occur anywhere in the intestinal tract. The most common site is the terminal ileum, and the least common site is the colon. Duplication of the cecum is very rare. The importance of these congenital lesions lies in the fact that they mimic other surgical disease processes and may result in significant morbidity if left untreated. Prompt recognition and treatment using combined radiologic and surgical management are associated with an excellent outcome. We experienced a case of cystic duplication in the cecum, which gave rise to partial intestinal obstruction and bleeding. We performed a resection of the cecum, including a part of the terminal ileum, and anastomosed in end-to-end fashion with a good result.

Tonsillar lymphangiomatous polyp is an uncommon hamartomatous lesion that generally arises from the tonsillar surface. Due to the uncommon clinical and pathological features of these polyps, pathologist and clinician may experience difficulty in correctly classifying them. Although this is a rare clinical and pathologic entity for pathologists and clinicians, the diagnosis is not so difficult if one has a bit of experience about that. Recently, we experienced a 37-year-old women with a pale lymphangiomatous polyp of 3x1.5 cm size, which was treated by tonsillectomy. We report this case with a review of literature.

BACKGROUND: Lung pericytes are important constituent cells of blood-air barrier in pulmonary microvasculature. These cells take part in the control of vascular contractility and permeability. In this study, it was hypothesized that change of lung pericytes might be attributable to pathologic change in microvasculature in acute lung injury. The purpose of this study was how hypoxia change proliferation and genetic expression in lung pericytes. METHODS: From the lungs of several Sprague-Dawley rats, performed the primary culture of lung pericytes and subculture. Characteristics of lung pericytes were confirmed with stellate shape in light microscopy and immunocytochemistry. 2% concentration of oxygen and 200muM CoCl2 were treated to cells. Tryphan blue method and reverse transcription-polymerase chain reaction were done. RESULTS: 1. We established methodology for primary culture of lung pericytes. 2. Hypoxia inhibited cellular proliferation in pericytes. 3. Hypoxia could markedly induce vascular endothelial growth factor(VEGF) and smad-2. 4. Hypoxia-inducible factor-1alpha (HIF-1alpha)was also induced by 2% oxygen. CONCLUSION: Viability of lung pericytes are inhibited by hypoxia. Hypoxia can stimulate expression of hypoxia-responsive genes. Pericytic change may be contributed to dysfunction of alveolar-capillary barrier in various pulmonary disorders.

BACKGROUND: Although cardiopulmonary resuscitation(CPR) is a very effective therapy in cardiac arrest, it is hard to prove the true effectiveness of CPR. Several studies about out-of-hospital and emergency department CPR exist, but only a few reports about in-hospital CPR are available. This study was designed to investigate in-hospital cardiac arrest, to analyze the result of CPR, and to evaluate the problems associated with in-hospital CPR. METHODS: A clinical analysis of 71 cases of in-hospital CPR announcement from January 2000 to August 2000 was performed. The initial rhythm on cardiac arrest, return of spontaneous circulation(ROSC), and the survivals were analyzed in the case of the 46 true cardiac arrest patients. RESULTS: During 8 months, there were 71 cases of in-hospital CPR announcement. Among them, there were 46 cases of true cardiac arrest and 25 cases of non-cardiac arrest. Of the 46 true cardiac-arrest cases, 27(58.7%) experienced ROSC, 15(32.6) survived for over 24 hours, and 7(15.2%) survived to be discharged. The initial rhythms on cardiac arrest were 30 cases(65.2%) of asystole, 14(30.4%) of PEA(pulseless electrical activity), and 2(4.3%) of ventricular fibrillation, with ROSC being 17 cases(56.7%), 9(64.3%) and 1(50.0%) cases and discharged survivors being 4 cases(13.3%), 3(21.4%) and 0(0.0%) cases, respectively. CONCLUSION: Extraordinarily high proportions of asystole and PEA were seen in the initial rhythm of cardiac arrest, and those were associated with high survival rates. Although further study is needed to evaluate the course leading to this high proportion of asystole and PEA, this result suggests that if the EMS system in the hospital is activated promptly and systematically, a better outcome will be achieved in case of cardiac arrest with asystole and PEA.

A gastric neuroendocrine carcinoma is very rare, and the histological diagnosis is very difficult. These carcinomas result in a poor prognosis because they are preceded by severe lymphovascular invasion and early metastasis. In particular, it is difficult to distinguish between adenocarcinoma and neuroendocrine carcinoma by endoscopy when no specific symptoms are present (e.g., dyspepsia, nausea). According to published articles in Korea, most cases were diagnosed as adenocarcinoma initially; however, they were confirmed postoperatively as neuroendocrine carcinoma based on a histological examination using immunohistochemical staining. A case of a 55-year-old man, who had an incidental finding of a subepithelial tumor during his health check-up, was recommended for an endoscopic submucosal dissection (ESD). But the patient was lost to follow-up for 4 years. When he was examined again, the size of the tumor had increased from the previous exam. He underwent ESD and was diagnosed with a well-differentiated neuroendocrine carcinoma.

BACKGROUND AND OBJECTIVES: Implantable cardioverter–defibrillators (ICDs) are indicated in patients with Brugada syndrome (BS), early repolarization syndrome (ERS), or idiopathic ventricular fibrillation (IVF) who are at high risk for sudden cardiac death. The optimal ICD programming for reducing inappropriate shocks in these patients remains to be determined. We investigated the difference in the mean cycle length of tachyarrhythmias that activated either appropriate or inappropriate ICD shocks in these three patient groups to determine the optimal ventricular fibrillation (VF) zone for minimizing inappropriate ICD shocks. SUBJECTS AND METHODS: We selected 41 patients (35 men) (mean age±standard deviation=42.6±13.0 year) who received ICD shocks between April 1996 and April 2014 to treat BS (n=24), ERS (n=9), or IVF (n=8). Clinical and ICD interrogation data were retrospectively collected and analyzed for all events with ICD shocks. RESULTS: Of the 244 episodes, 180 (73.8%) shocks were appropriate and 64 (26.2%) were inappropriate. The mean cycle lengths of the tachyarrhythmias that activated appropriate and inappropriate shocks were 178.9±28.7 ms and 284.8±24.4 ms, respectively (p<0.001). The cutoff value with the highest sensitivity and specificity for discriminating between appropriate and inappropriate shocks was 235 ms (sensitivity, 98.4%; specificity, 95.6%). When we programmed a single VF zone of ≤270 ms, inappropriate ICD shocks were reduced by 70.5% and appropriate shocks were missed in 1.7% of these patients. CONCLUSION: Programming of a single VF zone of ≤270 ms in patients with BS, ERS, or IVF could reduce inappropriate ICD shocks, with a low risk of missing appropriate shocks.
