Epidural analgesia is frequently used for the management of labor pain in parturients. The neurologic complications of epidural analgesia are rare, but they are catastrophic when they occur. We report here on a case of bilateral femoral neuropathy in a vaginal delivery patient with epidural analgesia. The patient complained of weakness of both thighs and numbness around both knees. Neurologic examination and electromyographic study revealed that they occurred due to the delivery itself. The patient had not fully recovered at eight weeks after delivery. The declining incidence of postpartum femoral neuropathy may reflect a reduced duration of labor in accordance with modern obstetric practice, and particularly the more frequent use of Caesarean delivery. The exact etiology of postpartum femoral neuropathy is unknown, and the possible factors are direct compression of nerves that are proximal within the pelvis by either the fetal head or birthing instruments, or this malady is the result of pressure induced ischemia at the level of the inguinal ligament when the pregnant woman is in the lithotomy position.

BACKGROUND: Calcium plays a key role in vascular contraction and regulates receptor sensitivity to certain neurotransmitters. Calcium channel blockers are useful in the treatment of both clinical and experimental hypertension. The present study was designed to examine whether there is an alteration of the activity of calcium channels in association with the development of hypertension. METHODS: Deoxycorticosterone acetate(DOCA)-salt hypertension was made by subcutaneous implantation of DOCA(200mg/kg)strip plus saline drinking(1%) and 2-kidney, 1 clip(2KIC)hypertension by clipping the left renal artery with a silver clip(internal gap of 0.2mm). They were used 4 weeks later. Age-matched normal rats served as a control. Mean arterial pressure(MAP) and heart rate(HR) were continuously recorded from the right femoral artery. The drugs were administered intravenously. RESULTS: Vehicle alone was without effect on MAP or HR. In normotensive rats, nifedipine infusion(5 and 10ug/kg/min)caused a dose-dependent decrease in MAP without significant changes in HR, while Bay k 8644(Bay K, 5 and 10 ug/kg/min) increased MAP transiently. Both the depressor response to nifedipine and the pressor response to Bay k were more marked in DOCA-salt hypetensive rats than in normotensive rats. The maximal changes in MAP indced by nifedipine(5 and 50 ug/kg) or Bay K(5 and 50 ug/kg) were also enhanced in 2KIC hypertensive rats as compared with control rats. CONCLUSION: These results indicate that calcium channel inhibitors and activators can affect on the regulation of blood pressure in an opposite fashion. It is also suggested that the activity of calcium channels might be altered in the developement of experimental hypertension.

A crossed occlusion resulting from the presence of posterior teeth in one arch but no opposing teeth in the opposite arch results in collapse of the vertical dimension. In this case, the patient has a class III malocclusion with crossed occlusion and anterior crossbite. In order to evaluate the proper vertical dimension, provisional denture was used to stabilize the vertical occlusal dimension for 3 months. After, provisional fixed restoration was used for the stabilizing occlusal relationship and aesthetic improvement for lip support. Definitive prosthesis in implants in the mandible and abutments in the maxillary were using Porcelain-fused-to-metal crown (PFM) crown and the maxillary unilateral edentulous area was treated with removable partial dentures. Through this, proper support of the posterior region and normal anterior occlusal relationship were formed, and the patient was able to obtain aesthetically and functionally satisfactory treatment results.

Purulent pericarditis is a rare condition with a high mortality rate. We report a case of purulent pericarditis subsequently caused by Candida parapsilosis, Peptostreptococcus asaccharolyticus, Streptococcus anginosus, Staphylococcus aureus, Prevotella oralis, and Mycobacterium tuberculosis in a previously healthy 17-year-old boy with mediastinal tuberculous lymphadenitis. The probable route of infection was a bronchomediastinal lymph node-pericardial fistula. The patient improved with antibiotic, antifungal, and antituberculous medication in addition to pericardiectomy.

BACKGROUND/AIMS: The Cdx-1 and Cdx-2 genes are intestinal transcription factors that may be involved in the regulation of proliferation and differentiation of intestinal epithelial cells. The Cdx-1 and Cdx-2 are expressed in the epithelium of the small intestine and colon but not in the normal epithelium of the esophagus and stomach. Conversely, aberrant Cdx-2 expression is often observed in the esophagus and stomach. We investigated the expression and role of Cdx-2 in intestinal metaplasia and gastric adenocarcinoma. METHODS: The gastric tissues obtained endoscopically were analyzed by the reverse transcriptase-polymerase chain reaction and histology. The Cdx-1 and Cdx-2 mRNA expression was confirmed and analyzed according to updated Sydney classification. Then, immunohistochemical study with monoclonal anti-Cdx-2 antibody was performed with gastric adenocarcinoma obtained by surgical resection. RESULTS: The prevalence of Cdx-1 and Cdx-2 mRNA expression was significantly higher in mucosa with intestinal metaplasia than mucosa without intestinal metaplasia. In immunohistochemical study, nuclear staining of Cdx-2 was strong in metaplastic mucosa, but weak in adjacent normal gastric mucosa (p<0.001). The expression of Cdx-2 in gastric adenocarcinoma was lower than in metaplastic mucosa (p<0.001). The Cdx-2 expression was also detected in 97% of intestinal type gastric adenocarcinoma and 61.5% of diffuse type gastric adenocarcinoma (p=0.003). CONCLUSIONS: Aberrant expression of Cdx-2 is observed in intestinal metaplasia and a subset of gastric adenocarcinoma, which is predominant in intestinal-type gastric adenocarcinoma. Therefore, Cdx-2 may play an important role in gastric carcinogenesis, especially in intestinal type adenocarcinoma.

INTRODUCTION: Mandibular third molar extraction is one of the most common procedures performed in oral and maxillofacial surgery units. Although the overall complication rate is low with most complications being minor, mandibular third molar removal is so common that the population morbidity of complications might be significant. Therefore, efforts to limit intraoperative or postoperative complications might have a significant impact in terms of enhancing the patient outcome. The aims of this study were to identify the position and angulation associated complications after mandibular third molar extractions. MATERIALS AND METHODS: This study surveyed 568 patients who had a mandibular third molar extracted, showed clinical complications and underwent a radiographic measurement of the available space, depth and spatial relationship. RESULTS: The results obtained were as follows: 1. The complications were a dry socket, nerve injury, root rest, infection, bleeding, hamatoma, and adjacent teeth injury. 2. There were no significant differences between the complication and ramus relationship (available space) of the mandibular third molar. 3. There were no significant differences between the complications and depth of the mandibular third molar. 4. There were no significant differences between the complications and spatial relationship of the mandibular third molar. CONCLUSION: There were no significant differences in the complication rate, ramus relationship, depth and spatial relationship of the mandibular third molar. This suggests that the position and angulation of the mandibular third molar may not have an impact on the complications. The relationship between the position and angulation of the mandibular third molar, and complications deserves a further study using longitudinal data.

Short stature and gonadal dysgenesis are two characteristic clinical features of Turners syndrome. Very rarely, patients with Turners syndrome may menstruate and even be fertile. We experienced a case of Turners syndrome with spontaneous sexual development and menstruation. A 16-year-old girl was referred for severe anemia and menometrorrahgia. She had nearly normal features, with the exception of a short stature and a single right kidney. Also, she had spontaneous development of secondary sexual characteristics. We performed and anemia study and evaluated her short stature. In chromosomal study of her bone marrow and peripheral blood lymphocytes, she was revealed to have monosomy 45,X. Herein, this case is reported, with a brief review of literature

Brain and skin metastasis from urothelial carcinoma of the bladder is rare. There have been few case reports of the clinical course of patients with metastatic urothelial carcinoma of the brain and skin. In the present case, a 60-year-old man had undergone radical cystectomy with an ileal conduit owing to urothelial carcinoma (T1N0M0). The patient developed dizziness 9 years later and a solitary brain tumor was discovered in his left cerebellar hemisphere. The tumor was totally resected and the mass was verified to be metastatic urothelial carcinoma. One year after the metastasectomy of the brain lesion, multiple erythematous nodular lesions developed on his abdominal skin. The skin lesions were excised and verified to be metastatic urothelial carcinoma. This report describes this case of urothelial carcinoma of the bladder that metastasized to the brain and abdominal skin.

BACKGROUND: Although rarefaction of myocardial angiogenesis has been shown to be associated with left ventricular (LV) systolic dysfunction in animal models of ventricular hypertrophy, this relationship has not been investigated in depth nor validated in humans. We aimed to analyze the relationship of myocardial angiogenesis with various functional and structural ventricular remodeling parameters in moderate to severe aortic stenosis (AS) patients with normal LV ejection fraction (LVEF). METHODS: A total of 38 moderate or severe AS patients with LVEF > 50% were enrolled for the current study and all patients underwent LV endomyocardial biopsy at the septum during aortic valve replacement. The biopsy specimens were stained for platelet endothelial cell adhesion molecule-1 (CD31) to analyze the density of blood vessels in the myocardium. RESULTS: The degree of myocardial angiogenesis tended to increase with worse myocardial systolic function, LV filling pressure and progressed ventricular hypertrophy (Spearman's rho = -0.388, p = 0.016 for LVEF; Spearman's rho = 0.442, p = 0.007 for E/e'; Spearman's rho = 0.424, p = 0.008 for LV mass index). The degree of myocardial angiogenesis was also significantly associated with the degree of aortic valve stenosis (Spearman's rho = -0.368, p = 0.023). There was significant difference in the degree of myocardial angiogenesis according to the LV geometry (p = 0.016 for mean difference between different LV geometry groups by analysis of variance). Significant predictors of myocardial blood vessel density were LV mass index (beta = 0.398, p = 0.010) and LVEF (beta = -0.313, p = 0.028). CONCLUSION: There is a close relationship between myocardial angiogenesis and LV remodeling in moderate to severe AS patients with normal LVEF, with angiogenesis increasing with LV hypertrophy. Further studies to demonstrate the mechanism underlying this phenomenon is warranted.
