Congenital biliary dilatation (CBD) or choledochal cyst has previously been considered a rarity; however, the number of cases reported in the literature has been increasing. It is generally accepted that there is a predominance in Japanese, as more than one-third of the cases are from Japanese literature. 相似文献

Abstract The efficacy of lithium carbonate in the first reported case of a female with mild mental disability who engaged in public and compulsive masturbation is described. The patient was born in 1975, and was 19 years old at first admission. A diagnosis of schizophrenia was initially suspected, therefore the patient was given medication including pimozide, haloperidol, carbamazepine, diazepam and levomepromazine. These medications, however, did not control the symptoms, and the patient showed several side effects, such as incontinence. Only lithium carbonate was efficacious among the medications administered; the patient's abnormal sexual beavior was significantly reduced and no conspicuous side effects were recognized. The mechanisms of lithium carbonate in controlling abnormal sexual behavior are discussed. 相似文献

Sjögren's syndrome (SS) is thought to be uncommon in children. An epidemiological study to describe the clinical features distinguishing SS in Japanese children was performed by sending questionnaires to hospitals. A total of 61 cases of SS were reported from 1290 hospitals. The diagnosis of SS was based on histopathological changes and/or sialographic changes in the salivary glands. Forty-two cases had primary SS and 19 were secondary SS with other autoimmune disorders. Fourteen cases (65%) of secondary SS were associated with systemic lupus erythematosus. In primary SS, the initial symptoms were systemic manifestations (fever, exanthema, arthralgia, etc) except for sicca symptoms. In laboratory studies, antinuclear antibodies, elevated serum IgG, rheumatoid factor, anti-Ro/SS-A antibodies and anti-La/SS-B antibodies were frequently observed. 相似文献

The effect of adrenergic blocking agents on gastrin and secretin secretion before and after a bolus arginine injection (arginine pulse) was investigated in normal subjects. Repeated arginine pulses given at 30-minute intervals caused abrupt and almost identical rises of plasma gastrin with each pulse. On the other hand, plasma secretin levels were unchanged by repeated injections of arginine. The increase in plasma gastrin induced by arginine pulse was significantly suppressed by the infusion of beta-adrenergic blocking agent, propranolol, while the infusion of alpha-adrenergic blocking agent, phentolamine tended to enhance the arginine-induced gastrin secretion slightly but not significantly. Whereas, the infusion of neither phentolamine nor propranolol had significant influence on secretin secretion. These results suggest that alpha- and beta-adrenergic receptors play an important role in the regulation of arginineinduced gastrin secretion. 相似文献

A case is reported of extrahepatic obstruction of the portal vein with the unusual complication of obstructive jaundice that resulted from compression of the common bile duct caused by cavernous transformation of the varicose network. It is surgically impossible to repair choledochal stenosis resulting from enlarged varices in the vicinity of the common bile duct. In this case, internal drainage from the biliary duct to the duodenum using a silastic tube and a reservoir implanted in the subcutaneous space successfully eliminated the jaundice. 相似文献

Cerulein-induced Pancreatic Polypeptide Secretion 总被引:2,自引:0,他引:2
KINSUKE TSUDA M. D. YUTAKA SEINO M.D. HIDEO SAKURAL M.D. SUSUMU SEINO M.D. JIRO TAKEMURA M.D. HIDESHI KUZUYA M.D. † HIDEKI ADACHI M.D. ‡ HIROO IMURA M.D. 《The American journal of gastroenterology》1980,74(4):355-358
Intramuscular administration of cerulein caused an abrupt rise in plasma pancreatic polypeptide (PP) in normal subjects. Pretreatment by atropine tended to lower the basal plasma PP level and significantly blunted the cerulein-induced PP secretion. It appears, therefore, that PP secretion induced by cerulein is under vagal control. In addition, in normal subjects, a gallbladder series first revealed a well-filled gallbladder of normal size and shape, which then contracted most strongly after a cerulein injection at a time corresponding exactly with the peak plasma PP levels produced by the cerulein. Since exogenous PP is known to cause a relaxation of the gallbladder, it is possible that endogenous PP plays an important role in gallbladder motility. 相似文献

To examine the characteristics of Haïssaguerre's slow potential (SP) specific to effective catheter ablation of the slow pathway in AV nodal reentrant tachycardia, the properties of SP and its recording site ware analyzed in 52 patients who underwent successful SP-guided ablation. The properties of SP included the ratio of the amplitude of SP to that of atrial potential (A)(SP/A), the SP duration, the interval between His-bundle potential (HP) and SP (HP-SP), the interval between A and SP (A-SP), the interval between SP and ventricular potential (V) (SP-V), and the ratio of A-SP to the interval between A and the V (A-SP/A-V). The SP recording site was determined by the ratio of the amplitude of A to that of V (A/V) and by the relative position of the ablation catheter on X ray (right anterior oblique projection), expressed as the ratio of the distance between the coronary sinus ostium and SP site to that between the coronary sinus ostium and HP recording site (relative SP position). Twenty-eight slow pathways were ablated with a single energy application, while the other 24 required applications ≥ 2. In all successful applications, SP/A, SP duration, HP-SP, A-SP. SP-V, A-SP/A-V, A/V, and relative SP position were 51 %± 25%, 28 ± 5 ms, -11 ± 9 ms, 57 ± 25 ms, 68 ± 13 ms, 46%± 9%, 15%± 13%, and 51%± 13%, respectively. A significant correlation was observed between the relative SP position and A-SP, and between the relative SP position and A-SP/A-V (r = 0.60 and 0.37, respectively), while it was not between the relative SP position and HP-SP, nor between the relative SP position and SP-V. When the characteristics of SP were comparatively analyzed between the effective and ineffective applications in 24 patients in whom applications ≥ 2 were required, there was no difference observed in HP-SP, A-SP, SP-V, A-SP/A-V, and A/V. However, SP/A, SP duration, and the relative SP position in the effective applications were all greater than those in the ineffective ones (56%± 20% vs 35%± 18%, P < 0.001; 29 ± 4 vs 26 ± 5 ms, P < 0.01; and 52%± 15% vs 33%± 11%, P < 0.001, respectively). These results indicate that SP with an amplitude over a half of A amplitude and recorded at the mid-septum of the tricuspid annulus can be a marker for successful slow pathway ablation. Although the local atrial electrogram appears late as the SP recording site shifts to the lower position, the timing of SP relative to HP and V remained unchanged, suggesting that SP is independent of the local atrial activation. 相似文献

Role of transferrin receptor 2 in hepatic accumulation of iron in patients with chronic hepatitis C 总被引:2,自引:0,他引:2
RUMI MIFUJI YOSHINAO KOBAYASHI NING MA QIN LI QIANG NAOHITO URAWA SHINICHIRO HORIIKE MOTOH IWASA MASAHIKO KAITO FABIO MALAVASI YUKIHIKO ADACHI 《Journal of gastroenterology and hepatology》2006,21(1):144-151
Background and Aim: Iron deposition in the liver is a common finding in patients with chronic hepatitis C (CH‐C). The mechanism of this hepatic accumulation of iron is not completely understood. This study assessed if the protein expression of transferrin receptor 2 (TfR2) is upregulated in the liver of patients with CH‐C and if TfR2 protein mediates iron accumulation during hepatitis C virus (HCV) infection. Method: Liver specimens from patients with CH‐C that underwent interferon (IFN) therapy (n = 23) and from patients with CH‐B (n = 18) were evaluated. Hepatic expression of TfR2 protein was analyzed by immunohistochemistry. Total hepatic iron score (THIS) was evaluated by Prussian blue staining. Results: TfR2 protein was expressed in the cell membrane and cytosol of hepatocytes. Cytosol TfR2 protein was found to co‐localize with Tf. THIS (P = 0.0198) and hepatic TfR2 (P = 0.0047) expression were significantly higher in CH‐C than in CH‐B. The change in THIS values (rho = 0.580, P = 0.0079) and the grade of histological activity (rho = 0.444, P = 0.0373) were significantly correlated with changes in TfR2 expression after IFN therapy. Conclusions: The protein expression of TfR2 is significantly associated with iron deposition in the liver in patients with CH‐C. HCV infection may affect the hepatic expression of TfR2, leading to iron accumulation in the liver. 相似文献
