Duodenal abscess is a rarely reported disease throughout the entire world. Duodenal abscesses are developed mostly from the complication of duodenal ulcer perforation, and only small percentage of duodenal abscesses are the result of cholecysto-duodenal fistula which was made by gall bladder perforation. We report a 84-year-old male patient who presented to the emergency department with severe anorexia and generalized weakness for 2 weeks. The upper gastrointestinal endoscopy done and revealed a protruding mass at the lesser curvature of the duodenal bulb. As soon as the mass was punched with a biopsy forceps, a large amount of abscess began to pour out into the intestinal lumen. Abdominal CT scan demonstrated the presence of an air-fluid level the in gall bladder and also abscess in the porta hepatitis which was located between the gall bladder and the duodenum. Because the patient refused any surgical intervention, we treated him conservatively with intravenous antibiotics. Patient's symptom of anorexia was slowly resolved, and patient was discharged 10 days later.

BACKGROUND AND OBJECTIVES: Fungi are found in normal flora in various amounts. However, fungi in chronic sinusitis are poorly understood, and it is not clearly defined whether it is a pathogen or simply a part of normal flora. The polymerase chain reaction (PCR) is proposed as a more reliable test to detect fungal DNA than the conventional culture technique. The aim of this study was to compare the sensitivity of conventional culture technique and PCR analysis in detecting fungus of the nasal cavity and to compare fungal species found in normal controls and patients with chronic sinusitis. MATERIALS AND METHOD: Sterile saline irrigation was performed and then mucin filled saline was collected from the nasal cavity of patients with chronic sinusitis and normal controls. Fungus culture and PCR analysis were carried out with irrigated saline. RESULTS: PCR for panfungal gene was positive in 92.5% and 97.5% while fungus cultures were positive in 23.3% and 30.5% of patients with chronic sinusitis and normal controls, respectively. There was no significant difference in the prevalence of fungus and species of fungus between patients with chronic sinusitis and normal controls. CONCLUSION: PCR for panfungal gene was more sensitive for fungus detection than fungus culture in patients with chronic sinusitis and normal controls. Presence of fungus alone was insufficient to implicate it as the pathogen of chronic sinusitis. It will be necessary to study further about fungal species in patients with chronic sinusitis and normal controls.

Enteritis cystica profunda (ECP) is characterized by mucin-filled cystic spaces that are partially lined by non-neoplastic columnar epithelium, and these are found in the wall of the small bowel. This is a very rare disease compared to cystica profunda involving the stomach or colon. The cause of ECP is still unclear. Most ECP is related to or it may accompany other intestinal diseases. We encountered one case of ECP of the duodenal bulb that presented as polyp, and this was not related to adenocarcinoma or any other intestinal diseases like Crohn's disease or ulcerative colitis. Endoscopic polypectomy was done and the ECP was later confirmed through histological evaluation.

Pendred syndrome is an autosomal recessive genetic disorder, which is characterized by sensorineural hearing loss, goiter and a positive perchlorate discharge test. It is caused by mutations of the PDS gene, and its clinical characteristics vary widely. The thyroid function in most cases is normal, or shows only mild hypothyroidism. In Pendred syndrome, there is an organification defect that leads to defective thyroid hormone synthesis, followed by chronic TSH stimulation. Herein is reported a case of a follicular thyroid carcinoma associated with Pendred syndrome. To our knowledge, this is the first case reported in Korea. The patient presented with a huge anterior neck mass, sensorineural hearing loss and a positive perchlorate discharge test. Fine needle aspiration cytology suggested malignancy of the thyroid, and a total thyroidectomy, with central compartment node dissection, was performed. The pathology from the thyroid mass showed a poorly differentiated follicular thyroid carcinoma

Cough syncope is characterized by the loss of consciousness occurring after vigorous coughings. There are approximately 90 reported cases of cough syncope within the medical literature. Most cases involving middle aged, overweight and chronic bronchitic male smokers. Although many studies have been published in the medical literature, the mechanism and pathophysiology for cough syncope has not been well established. Cough syncope is treated by correcting the underlying cause when identified, or by avoiding conditions that may cause the cough syncope. In addition, cough suppression modalities can also be used. We herein report 3 cases of cough syncope presenting in lung cancer patients.

A 48 year-old man was referred to our Department with a headache, and also presented with an elevated serum ACTH level, but without an elevated serum cortisol. Although there was no clinical evidence of Cushing's syndrome, a brain CT and MRI showed a 4x4.5 cm sized pituitary mass, which was successfully removed by a transsphenoidal approach (TSA). A histopathological examination revealed the mass to have an ACTH positive reaction. Therefore, through hormonal and pathological evaluation, a silent corticotroph-cell adenoma (SCCA), with an elevated serum ACTH level, was diagnosed. Although reports on SCCA have been recently increased, this case is reported because these kinds of tumor are still rare, and those SCCA with an elevated serum ACTH even more so

This study aimed to explore the effects and mechanisms of total flavones of Abelmoschus manihot(TFA), the extracts from traditional Chinese medicine indicated for kidney diseases, on insulin resistance(IR) and podocyte epithelial-mesenchymal transition(EMT) in diabetic kidney disease(DKD), and further to reveal the scientific connotation. Thirty-two rats were randomly divided into a normal group, a model group, a TFA group, and a rosiglitazone(ROS) group. The modified DKD model was induced in rats by methods including high-fat diet feeding, unilateral nephrectomy, and streptozotocin(STZ) intraperitoneal injection. After modeling, the rats in the four groups were given double-distilled water, TFA suspension, and ROS suspension correspondingly by gavage every day. At the end of the 8th week of drug administration, all rats were sacrificed, and the samples of urine, blood, and kidney tissues were collected. The parameters and indicators related to IR and podocyte EMT in the DKD model rats were examined and observed, including the general condition, body weight(BW) and kidney weight(KW), the biochemical parameters and IR indicators, the protein expression levels of the key signaling molecules and structural molecules of slit diaphragm in the renal insulin receptor substrate(IRS) 1/phosphatidylinositol 3-kinase(PI3K)/serine-threonine kinase(Akt) pathway, foot process form and glomerular basement membrane(GBM) thickness, the expression of the marked molecules and structural molecules of slit diaphragm in podocyte EMT, and glomerular histomorphological characteristics. The results showed that for the DKD model rats, both TFA and ROS could improve the general condition, some biochemical parameters, renal appearance, and KW. The ameliorative effects of TFA and ROS were equivalent on BW, urinary albumin(UAlb)/urinary creatinine(UCr), serum creatinine(Scr), triglyceride(TG), and KW. Secondly, they could both improve IR indicators, and ROS was superior to TFA in improving fast insulin(FIN) and homeostasis model assessment of insulin resistance(HOMA-IR). Thirdly, they could both improve the protein expression levels of the key signaling molecules in the IRS1/PI3K/Akt pathway and glomerulosclerosis in varying degrees, and their ameliorative effects were similar. Finally, both could improve podocyte injury and EMT, and TFA was superior to ROS. In conclusion, this study suggested that podocyte EMT and glomerulosclerosis could be induced by IR and the decreased activation of the IRS1/PI3K/Akt pathway in the kidney in DKD. Similar to ROS, the effects of TFA in inhibiting podocyte EMT in DKD were related to inducing the activation of the IRS1/PI3K/Akt pathway and improving IR, which could be one of the scientific connotations of TFA against DKD. This study provides preliminary pharmacological evidence for the development and application of TFA in the field of diabetic complications.
