A case of recrudescent groove pancreatitis, which was in remission by proximal gastrectomy with vagotomy for gastric cancer]

This report describes our experience with a 60 year old male who suffered from a recrudescence of groove pancreatitis. He had been treated by conservative medication therapy by proton pump inhibitor used for therapy of duodenal ulcer, and was in remission. During a follow-up one year later, endoscopy revealed gastric cancer, for which a proximal gastrectomy and vagotomy were performed. The patient continues to remain in remission for the groove pancreatitis. Our experience with the clinical course of this disease, in which treatment for duodenal ulcer was used effectively, offers new insights into the progression and therapy of groove pancreatitis.     

Malignant Rhabdoid Tumor of the Breast: A Case Report

A 66-year-old woman time of 10 days. One month after radicalmastectomy, there was local recurrence, followed by multiplepulmonary metastases, and the patient died of respiratory failure5 months after surgery. The gray-white-colored tumor measured13x12x;10 cm, and its border was well defined. The tumor wascomposed of diffusely growing round or polygonal cells withvesicular nuclei, prominent nucleoli, and ample cytoplasm containingeosinophilic inclusions. Lymph node involvement was widespread.Both vimentin and keratin were clearly demonstrated by immunohistochemicalstaining. Ultrastructural studies revealed that the MRT cellscontained cytoplasmic whorls of intermediate filaments.     

An Evaluation of the Residual Activity of Antiseptic Handrub Lotions: An ‘In Use’ Setting Study

An evaluation of the residual activity of quick-drying agents (alcoholic solutions) used for hygienic hand disinfection is described. We looked for residual efficacy following hand disinfection with soap and water alone or followed by one of two alcoholic handrub lotions supplied from an automatic hand washing machine. The bacterial counts on the hands obtained before and within 2 successive hours after disinfection showed that alcoholic chlorhexidine was the most effective for 10 minutes after contamination of the hands. WELPAS® (alcoholic chlorbenzarconium) followed this in its immediate effect and was better than soap and water alone. There were no significant differences after 30‘ or 120‘ between the three disinfecting methods.     

Epidural midazolam with saline--optimal dose for postoperative pain]

Optimal dose of epidural midazolam with saline for postoperative pain relief was investigated. Forty three patients for upper abdominal surgery were divided into 5 groups. Each group had either 10 ml saline only (saline group), 10 ml saline + midazolam 0.025 mg.kg-1 (0.025 group), 10 ml saline + midazolam 0.05 mg.kg-1 (0.05 group), 10 ml saline + midazolam 0.075 mg.kg-1 (0.075 group), or 10 ml saline + midazolam 0.1 mg.kg-1 (0.1 group) administered epidurally for complaint of postoperative pain. Blood pressure (BP), heart rate (HR), respiratory rate (RR) and sedation score (SS) were monitored for 120 minutes, and the time interval for next analgesics (TNA) was checked. In each group, BP was unchanged compared with preinjection level. HR changes were less in 0.05 and 0.1 group than in others. RR changes were less in 0.025 and 0.05 group than in others. Optimal SSs were obtained in 0.025 and 0.05 groups. In 0.075 and 0.1 groups, many patients fell into complete sleep (not responded to verbal command). TNA was about 2 hours in 0.025 and 0.05 groups, over 6 hours in 0.075 and 0.1 groups. Complete sleep was the cause of long TNA in 0.075 and 0.1 groups. It was concluded that optimal dose of epidural midazolam with saline 10 ml was 0.05 mg.kg-1 for postoperative pain relief after upper abdominal surgery.     

Effects of bifemelane on the free fatty acid levels during ischemia

Using the four-vessel extracranial one staged occlusion model of adult Wistar rats, we analyzed quantitatively released free fatty acids during ischemia. Also have we analyzed the effect of bifemelane to reduce free fatty acid accumulation after the onset of ischemia. Bifemelane (15 mg/kg, 30 mg/kg) and saline as control were intraperitoneally administered to adult Wistar rat prior to 30 minutes of experimentally induced ischemia. The results obtained were analyzed by one or two way analysis of variance (ANOVA). Physiological variables (systemic arterial pressure, PaO2, PaCO2, pH) did not change significantly in all four experimental groups. Total free fatty acid levels (sum of 5 fatty acid) increased significantly after ischemia (30 minutes). Higher dose (30 mg/kg) of bifemelane administration significantly reduced total free fatty acid accumulation, though lower dose (15 mg/kg) did have no effect. Bifemelane (30 mg/kg) reduced significant accumulation in the amount of saturated and monounsaturated fatty acid (palmitic acid [16:0], stearic acid [18:0] and oleic acid [18:1]). Arachidonic (20:4) and docosahexaenoic (22:6) acid failed to show any effective reduction by bifemelane pre-treatment of lower nor higher dose. Bifemelane is supposed to have many pharmacological effects such as increase in cerebral blood flow, augmentation of glucose uptake, monoamine metabolism, cerebral vasodilatation and platelet antiaggregation. Free fatty acid accumulation is effectively suppressed by the higher dose of bifemelane administration. Although the exact mechanism are not clearly identified by the result obtained in this experiment, selective inhibition of accumulation in saturated and monounsaturated fatty acids by bifemelane pretreatment may be obtained by the improvement of energy metabolism, which may help to reacylation of fatty acid into phospholipid.     

Surgical Treatment of Intractable Seizures Due to Hypothalamic Hamartoma

Summary: A 6.5-year-old boy developed seizures at age 2.8 years consisting of episodes of unconsciousness and laughing attacks. By age 6 years, multiple seizure types, including generalized tonic-clonic (GTC), complex partial (CPS) and akinetic seizures, and drop attacks were occurring several times daily. EEG showed multifocal epileptic discharges. Antiepileptic drugs (AEDs) did not control the seizures. With progression of the epilepsy, cognitive deterioration developed. There were no manifestations of precocious puberty. Neuroimaging disclosed a suprasellar mass in continuity with the hypothalamus, and a diagnosis of hypothalamic hamartoma was made. After surgical resection of the hamartoma, the seizures were completely alleviated, and the epileptic EEG discharges disappeared. Improvement of mental function was also noted.     

Angiogenesis factors in ocular tissues of normal rabbits on chorioallantoic membrane assay

Recent studies have shown that angiogenesis-stimulatory factors exist in ocular tissues and play a crucial role in the development of some eye disorders such as diabetic retinopathy. However, there are few reports that studied location of angiogenesis factors in ocular tissues of experimental animals. We studied angiogenesis factors in ocular tissues of normal rabbits by chorioallantoic membrane (CAM) assay. Extracts derived from the retina, iris-ciliary body and optic nerve showed an evident activity of angiogenesis. Retinal extracts at 10 micrograms showed a strong angiogenic activity in 50% of CAMs (p less than 0.01). On the other hand, bovine serum albumin which is heterogeneous protein showed only a slight angiogenic activity at a high concentration (1,000 micrograms). The iris-ciliary body and optic nerve showed also an angiogenic activity as did the retina. Extracts from the heart, liver and serum showed no activity of angiogenesis. Thus, angiogenic activity was strongly present in the ocular tissues, especially in retina of the normal rabbits.     

Relationship between left ventricular systolic function and the myocardial gray level distribution in patients with idiopathic dilated cardiomyopathy]

Dilated cardiomyopathy (DCM) is characterized by progressive left ventricular (LV) systolic dysfunction of nonspecific etiology. Fifty-nine DCM patients were serially observed by echocardiography for 4.5 +/- 2.6 years, and 7.3 +/- 3.4 times M-mode and two-dimensional echocardiography was performed during the observation period using SSH-11A (Toshiba). To assess LV systolic function, ejection fraction was calculated by Pombo's method. Myocardial gray level distribution shown by echocardiography was calculated to assess the myocardial tissue character. Two-dimensional echocardiographic images were obtained in the parasternal short-axis view, recorded on U-matic videotape, and transferred to an image processing computer system (MIPRON, Kontron). The images were digitized and stored on the computer. The regions of interest (ROI) were placed in the LV septum, posterior papillary muscle, posterior wall, anterior papillary muscle and entire LV wall. The gray level distributions in each ROI and its quantitative parameters (mean, SD, skewness, excess) were calculated. The corrected myocardial gray level of every ROI (CMD) was also calculated and expressed as the ratio to the mean gray level of the LV cavity. Seven patients exhibited significant decreases in ejection fraction (more than 10%) during the observation period (group A); the remainders showed less change (group B).(ABSTRACT TRUNCATED AT 250 WORDS)
