Temporal bone findings in trisomy 18 and 21 syndromes

The temporal bones from fetuses with known autosomal trisomy syndromes were examined histopathologically after spontaneous or induced abortions. Fetal ages dated from the 17th to the 24th week of pregnancy. In all, 17 temporal bones from nine fetuses were studied and included seven cases of Down's syndrome and two of Edwards' syndrome. Temporal bones from fetuses with Down's syndrome had more abnormalities of the external and middle ears than of the inner ear. The bones from the fetuses with Edwards' syndrome showed abnormalities of the external or middle ear and retarded development of the inner ear (failed ossification of the otic capsule and unformed organ of Corti).     

Prognostic significance of cytochemical analysis of leukemic M2 blasts

Cytochemical analysis of leukemic blasts from 46 patients with acute myeloblastic M2 leukemia (according to the FAB classification) was performed before and after cytostatic therapy, and compared with findings obtained in 20 age- and sex-matched control subjects. Cytochemical findings for myeloperoxidase (MPO), Sudan black B, acid phosphatase and alpha-naphthyl-acetate esterase (ANAE) were related to the achievement of the first complete remission (CR),i.e. data were compared after the patients had been divided into CR and non-CR groups. The analysis clearly showed that a high proportion of myeloperoxidase- and, to a lesser extent, Sudan black B-positive blasts before treatment may have constituted a significantly unfavourable prognostic factor.

Percutaneous radiofrequency rhizotomy of lumbar spinal facets: The results of 46 cases

The results of percutaneous radiofrequency rhizotomy of lumbar spinal facets in 46 patients followed at least three months (mean 15 months) are reported and compared with those reported previously. Satisfactory pain relief three months after the procedure was achieved in 36.4 percent of patients without operations and in 41.7 percent of patients with operations other than fusion.No patient had previously undergone fusion.Treatment of low-back pain by using radio-frequency thermocoagulation of spinal facets is a simple, safe, and well-tolerated procedure. It can be used to relief of pain in spite of decreasing rates of success within the follow-up period.     

Chlamydial infections and male infertility

Chlamydial infections may be difficult to diagnose due to the silent symptoms and difficulty in culturing. An infectious process may impair fertility by adversely affecting sperm functions, resulting in testicular damage or causing obstruction of the genital tract. In our study, we tried to find Chlamydial antigen by using EIA (Enzyme Immune Assay) and to compare the Ag(+) and Ag(−) groups according to semen parameters. Except for semen volume, we found significant differences in density, morphology, motility and viability (intervolume p>0.05, interdensity p<0.01, intermorphology p<0.001, intermotility p<0.001 and interviability p<0.001).     

腹泻型与便秘型肠易激综合征直肠肛管动力和感觉功能的不同特点

目的 研究腹泻型与便秘型肠易激综合征（IBS）病人直肠肛管动力和直肠感觉功能的不同特点。方法 选择IBS病人85例，分成两组。其中腹泻组52例，便秘组33例，20例健康志愿者为对照组，采用PC Polygraf ID高分辨率多道胃肠功能测定仪，分别测定直肠肛管压力、直肠感知阈值、排便阈值、最大耐受量和直肠肛门抑制反射最低充气量。结果IBS病人的直肠静息压、肛管静息压和直肠肛门抑制反射最低充气量与健康对照组比较无显著性差异。腹泻组的最大缩窄压和排便阈值显著低于健康对照组。便秘组的松弛压、直肠感知阈值、排便阈值和最大耐受量显著高于健康对照组。结论腹泻型IBS病人的症状与最大缩窄压和排便闽值降低有关；而便秘型则与松弛压、直肠感知阈值、排便阈值和最大耐受量显著增高有关。
