Diffuse diabetic glomerulosclerosis in a patient with impaired glucose tolerance: report on a patient who later develops diabetes mellitus.

Diabetic glomerulosclerosis might be seen in diabetics but its presence in patients with impaired glucose tolerance is quite rare. A 31-year-old woman who was admitted to our department was diagnosed with hypertension, nephrotic syndrome and impaired glucose tolerance. Her renal biopsy was compatible with diabetic glomerulosclerosis. She developed overt diabetes mellitus (DM) after one year of impaired glucose tolerance. Hypertension might have accelerated the progression of diabetic nephropathy.

Chylous ascites after liver transplantation with mesentero-portal jump graft.

Chylous effusions and lymphatic leaks occur after trauma, malignant disease, primary lymphatic disorders, and parasitosis, and rarely after abdominal surgery. Chylous ascites after orthotopic liver transplantation is a rare complication. We report a case of chylous ascites occurring after hepatic transplantation with a mesentero-portal venous jump graft, successfully treated with conservative management.

Intermittent mode reversion to VOO of a dual chamber pacemaker model.

This report describes an asymptomatic patient with a DDDR pacemaker system (Inos Cls, Biotronik) that showed intermittent mode reversion to VOO and sometimes to VVI without a detectable source of electromagnetic interference and oversensing. Patients with this Biotronik model should be carefully assessed along with a surface ECG before placing the programming head.

Follow-up of a patient with chronic hepatitis C-associated cryoglobulinemia during four and a half years of maintenance interferon treatment.

In this report, we present a patient with chronic hepatitis C-associated cryoglobulinemia who was kept on maintenance interferon treatment because of flare-ups in cryoglobulinemia-associated signs and hepatitis after withdrawal, dose reduction, and increase in dose intervals of interferon. This type of interferon use for treatment of cryoglobulinemia gave us a chance to observe the long-term effects of interferon on cryoglobulinemia and chronic hepatitis C remission for biochemical, virologic, and histologic aspects.

Right ventricular aneurysm complicating right ventricular infarction.

Right ventricular (RV) involvement commonly occurs in patients with acute inferior myocardial infarction and is associated with high mortality and morbidity. RV dysfunction and dilatation commonly recover in survivors; chronic RV dyskinesia and failure are rare complications. This case report presents a patient in whom an isolated RV aneurysm complicates a RV involvement of acute inferior-posterior myocardial infarction.

[Quantitative ultrasonic myocardial texture analysis of the diabetic heart].

OBJECTIVE: Contraction and relaxation of the heart cause decrease and increase in myocardial video intensity (MVI) recorded from echocardiographic images, respectively. The present study was planned to compare this physiological cyclic variations of MVI in patients with type 1 diabetes mellitus and healthy subjects. METHODS: For this purpose, standard echocardiographic examination was performed to 18 young patients (age 23.2+6.4; range: 15-37 years) with insulin dependent type 1 diabetes mellitus (diabetes duration: 7.8+5.6; range: 1-17 years) and 14 age and sex matched controls. In all subjects, end-diastolic and end-systolic 2D echocardiographic images of 3 consecutive beats that had been recorded on videotapes were digitized. The quantitative analysis of digitized imaging was performed with the help of a calibrated digitization system in order to calculate the septum and the posterior wall textural parameters. The cyclic variation index (CVI) of the mean gray level (MGL) was calculated according the formula: (MGL dias- MGL diast x 100. RESULTS: Among the groups, left ventricular diastolic dimension-index, fractional shortening, E/A ratio, and isovolumic relaxation time showed no statistically significant differences, while septum and (8.3+1.1 vs. 7.3+0.9 mm; p=0.016) and posterior wall thickness (8+0.6 vs. 6.8+1.1mm; p=0.004) and E-deceleration time (167+23 vs. 140=19 msec.; p=0.003) were significantly higher in diabetics. The diabetic patients showed significantly lower CVI both for septum (18.2+11.5% vs. 39.3+11.5%; p=0.0001) and posterior wall (16.4+16% vs. 40.5+9.2%; p=0.0001), respectively. CONCLUSIONS: Altered videoensitometric parameters possibly represent a preclinical alteration, conceivably related to the myocardial collagen content increase, which does not necessarily indicate an actual disease but may be considered an early marker of the histopathologic findings of diabetic cardiomyopathy.

Amantadine monotherapy of chronic hepatitis C patients infected with genotype lb.

We aimed to test the efficacy of amantadine in chronic hepatitis C (CHC) patients infected with genotype b. Twenty patients completed treatment with amantadine HCl, 100 mg b.i.d., for 6 months. Non-sustained biochemical improvement was observed without loss of HCV-RNA. We conclude that amantadine monotherapy is not effective in CHC.
