Herniation of intervertebral disc usually occurs posterolaterally. A thorough review of the recent radiological literature revealed only a single case report of anterior intervertebral disc hernitation demonstrated by computed tomography (CT). We report another such case. 相似文献

We have compared insulin concentrations measured by radioimmunoassay (RIA) in plasma from 50 fasting non-insulin-dependent diabetics (NIDDM) with those measured by a new monoclonal antibody-based two-site immunoradiometric assay (IRMA) of insulin (which has no significant cross-reaction with proinsulin-like molecules). We find that the RIA measures the sum of the insulin and proinsulin like molecules and that the IRMA insulin concentrations are 38% of those measured by the RIA in those diabetic subjects. We conclude that the importance of insulin deficiency in NIDDM may have been obscured by this error. 相似文献

RESPIRATORY COMPLICATIONS AND HYPOXIC EPISODES DURING INHALATION INDUCTION WITH ISOFLURANE IN CHILDREN 总被引:2,自引:0,他引:2
We have studied the incidence of respiratory complications andhypoxic episodes during inhalation induction with isofluranein 75 healthy unpremedicated children. Problems occurred lessfrequently when 4% isoflurane in oxygen was used from the outsetthan with traditional techniques using nitrous oxide and a graduallyincreasing inspired vapour concentration. The improved resultsobserved with the former method may be secondary to more rapiduptake of vapour so that the second stage of anaesthesia characteristicof anaesthetic ethers is shortened considerably. 相似文献

Electroanatomic Mapping to Identify Breakthrough Sites in Recurrent Typical Human Flutter 总被引:4,自引:0,他引:4

SRA, J., et al. : Electroanatomic Mapping to Identify Breakthrough Sites in Recurrent Typical Human Flutter. The accuracy of conventional techniques in localizing previous radiofrequency (RF) ablation sites and thus breakthrough sites of recurrent atrial flutter is somewhat limited. We investigated the role of electroanatomic mapping for identifying breakthrough sites or "gaps" at the tricuspid annulus and inferior vena cava (IVC)/eustachian ridge isthmus to help RF ablation in patients with recurrent typical flutter. Twelve patients ( 8 men, 4 women, age 63 ± 10 years ) with recurrent typical atrial flutter were included in the study. An electroanatomic mapping system (CARTO) was used to create a voltage map and activation and propagation patterns in the right atrium. Detailed voltage, activation, and propagation mapping of the tricuspid annulus and IVC/eustachian ridge isthmus allowed precise identification of gaps in all 12 patients at the tricuspid annulus (eight sites), IVC ridges (two sites), mid-isthmus region (one site), and tricuspid annulus and IVC ridges (one site). Radiofrequency energy directed at these sites eliminated atrial flutter in all 12 patients, confirmed by noninducibility of atrial flutter and demonstration of conduction block during atrial pacing on either side of the lesion lines. During a mean follow-up of 14.8 ± 3.5 months ( range 8–19 months ), paroxysmal atrial flutter recurred in only one patient and was subsequently treated with amiodarone, although this had been ineffective prior to ablation. Electroanatomic mapping can precisely identify gaps in the lesion line responsible for breakthrough of recurrent typical atrial flutter at the tricuspid annulus and at the IVC/eustachian ridge isthmus. These sites can be targeted with RF ablation with a high degree of success. 相似文献

Primary sclerosing cholangitis: An experience from India 总被引:1,自引:0,他引:1

Primary sclerosing cholangitis (PSC) is considered to be rare in India. The aim of the present study was to investigate the incidence, clinical profile and outcome of PSC seen in a tertiary care centre. Over a period of 10 years (July, 1984-June, 1994) 18 patients of PSC were diagnosed at cholangiography (14 patients by endoscopic retrograde cholangiopancreatography, two patients by percutaneous transhepatic cholangiography and two patients by both methods). The presence of secondary causes, such as choledocholithiasis, biliary tract surgery, congenital biliary tract anomalies, cholangiocarcinoma and pancreatic diseases, were excluded. These patients were evaluated retrospectively with respect to their clinical presentation, radiological findings, presence of associated idiopathic ulcerative colitis (IUC), treatment instituted and outcome. The mean (±s.d.) age at diagnosis of PSC was 39.0 (±16.1) years with a male: female ratio of 1.57:1. Nine (50%) patients had associated IUC. The diagnosis of IUC preceded that of PSC in all but one case. Fifteen (83.3%) patients had cholestatic jaundice at presentation, while three (16.7%) patients had asymptomatic rise of alkaline phosphatase. Three (16.7%) patients had recurrent cholangitis and five (27.8%) patients developed portal hypertension during the course of the disease. At cholangiography, intrahepatic radicles were involved in all and extrahepatic radicles in 12 (66.6%) cases. Patients were managed with steroids (n= 7), colchicine (n= 3), ursodeoxycholic acid (UDCA; n= 2) and methotrexate (n= 1), along with symptomatic measures. Mean duration of follow up available in 11 (61%) patients was 20.1 months (range: 1 month-8 years). Four (36.4%) patients died. Steroids and colchicine did not have any effect while the one patient on UDCA and one on methotrexate showed improvement. In conclusion, in India PSC does not seem to be a rare entity. Its clinical profile and outcome are somewhat similar to those seen in Western countries. 相似文献
