We review 12 consecutive cases of pre-macular fibrosis (PMF) treated by vitreous surgical techniques. The causes of PMF included retinal detachment surgery in four patients, idiopathic in three patients, laser treatment in three patients, pars planitis in one patient and diabetic retinopathy in one patient. The membrane was successfully removed in all the patients. One patient developed a retinal detachment that was repaired successfully. All patients had improved visual acuity (VA) of two Snellen lines or more and six patients achieved VA of 6/12 or better. Patients with PMF following retinal detachment had poorer final VA. 相似文献

Obstructive jaundice secondary to benign hepatic cyst 总被引:1,自引:0,他引:1
A case of hepatic cyst causing obstructive jaundice is presented. Following percutaneous aspiration of the cyst, the jaundice was relieved. Modern interventional radiologic techniques can provide prompt diagnosis and treatment, thus avoiding major surgery and prolonged hospitalization. 相似文献

BackgroundThe antiatherogenic functions of high density lipoprotein (HDL-C) include its role in reverse cholesterol transport, but to what extent the concentration of HDL-C interferes with the whole-body cholesterol metabolism is unknown. Therefore, we measured markers of body cholesterol synthesis (desmosterol and lathosterol) and of intestinal cholesterol absorption (campesterol and β-sitosterol) in healthy subjects that differ according to their plasma HDL-C concentrations.MethodsHealthy participants presented either low HDL-C (< 40 mg/dl, n = 33, 17 male and 16 female) or high HDL-C (> 60 mg/dl, n = 33, 17 male and 16 female), BMI < 30 kg/m2, were paired according to age and gender, without secondary factors that might interfere with their plasma lipid concentrations. Plasma concentrations of non-cholesterol sterols were measured by the combined GC–MS analysis.ResultsPlasma desmosterol did not differ between the two groups; however, as compared with the high HDL-C participants, the low HDL-C participants presented higher concentration of lathosterol and lower concentration of the intestinal cholesterol absorption markers campesterol and β-sitosterol.ConclusionPlasma concentrations of HDL, and not the activities of LCAT and CETP that regulate the reverse cholesterol transport system, correlate with plasma sterol markers of intestinal cholesterol absorption directly, and of cholesterol synthesis reciprocally. 相似文献

Receptors for peanut agglutinin (Arachus hypogea) in childhood acute lymphoblastic leukemia: possible clinical significance 总被引:2,自引:0,他引:2
The presence of lymphocyte receptors for peanut agglutinin in significant numbers (greater than 15%) was identified on leukemic cells from T-cell acute lymphoblastic leukemia (T-ALL) (3/4), B-cell ALL (B- ALL) (2/4), null cell ALL (8/17), and on normal fetal thymic lymphocytes but not on normal human peripheral blood lymphocytes. Peanut agglutinin (PNA) binding was blocked specifically on leukemia lymphoblasts and thymic lymphocytes by the addition of galactose to the medium. When all immunologic subgroups of ALL are combined, preliminary data suggest that of the 13 ALL patients having greater than 15% PNA- positive lymphoblasts, 8 had relapsed, whereas none of the 12 ALL patients with less than 15% PNA-positive cells have recurrent disease at this time. It is likely that analysis of PNA receptors on ALL lymphoblasts may be a useful adjunct to the existing clinical and immunologic prognostic indicators. 相似文献
