A Chinese adolescent girl with Fechtner-like syndrome

We describe a 15-y-old girl with Fechtner-like syndrome, who is the first Chinese reported to have this rare syndrome. She presented with left homonymous hemianopia and neuroimaging revealed haemorrhage in both parietal and occipital lobes. Peripheral blood smear showed macrothrombocytopenia and intracytoplasmic inclusion bodies inside leucocytes. Thrombocytopenia and proteinuria responded to intravenous immunoglobulin and pulsed methylprednisolone. This case illustrates that life-threatening haemorrhage can occur in patients with Fechtner syndrome. Although there was no effective treatment reported in the literature, high dose steroid and immunoglobulin seemed to be useful in our patient. Our patient also had nephritic-nephrotic syndrome with renal insufficiency, which is unusual in adolescent female patients.     

The use of the helium-neon laser in the treatment of amblyopia in children

The authors analyze the efficacy of He-Ne laser therapy of amblyopia of various origins in 48 children (81 eyes). Group 1 children were not treated at all in order to assess the visual function background fluctuations (absolute controls). Along with He-Ne laser, used in Group 2, a 'placebo', slit lamp with blinking light, was used in Group 3. Vision acuity was assessed with the use of Sivtsev-Golovin's and Orlova's tables and by visocontrastometry in a blind test. Common visometry has shown a reliable and approximately similar improvement of the vision acuity in Groups 2 and 3 patients, whereas visocontrastometry has not detected any changes of visual function in all the 3 groups. These results cast doubt on the true efficacy of He-Ne laser stimulation of visual function, at least in children, and once again demonstrate that such investigations may be carried out only with a reliable ('blind') control and placebo.     

The use of lyophilized plasma as a reference sample for determining factor VIII]

The activity of lyophilized Soviet reference plasma Factor VIII was measured by a single-stage Papayan and Khrolova's method. This factor is referent in respect of the prothrombin complex factors, stored for 18-43.5 months. Factor VIII activity was found to be within 55-135 percent. Differences in the values of antihemophilic globulin activities obtained in parallel studies in different days may be explained by the fact that the native control was not standard. The results are promising as regards the possibility of using lyophilized donor reference plasma as a reference reagent for estimation of Factor VIII activity.     

SUICIDE ATTEMPT DUE TO METOCLOPRAMIDE-INDUCED AKATHISIA

Akathisia as a side-effect of metoclopramide has received increasing attention in consultation-liaison psychiatry in recent years. A case of metoclopramide-induced akathisia resulting in a suicide attempt is reported in order to highlight the suffering of such patients and the factors that lead to misdiagnosis.     

Relationship between parameters of lipid peroxidation during obstructive jaundice and after bile flow restoration

Restoration of bile flow after 9-day cholestasis in rat liver normalized the content of lipid peroxidation products. The removal of the cholestatic factor after 12-day cholestasis was not followed by recovery of these parameters. We showed that measurement of serum concentration of lipid peroxidation products in patients with cholelithiasis during the preoperative period holds promise for selection of the optimum time for surgical treatment and prediction of the risk of postoperative complications. __________ Translated from Byulleten’ Eksperimental’noi Biologii i Meditsiny, Vol. 145, No. 1, pp. 39–42, January, 2008     

Predictive value of normal sperm morphology: a structured literature review

The aim of the study was to conduct a structured review of theliterature published on the use of normal sperm morphology,as an indicator of male fertility potential in the in-vitrofertilization (IVF) situation, and to establish the universalpredictive value of this semen parameter. Published literaturein which normal sperm morphology was used to predict fertilizationand pregnancy, during the period 1978-1996, was reviewed. Atotal of 216 articles were identified by the sourcing methodology,but only 49 provided data that could be tabulated and analysed.Of these, only 18 provided sufficient data for statistical analysis.Fifteen studies used the strict criteria to evaluate sperm morphology,two used World Health Organization (WHO) guidelines and oneused both the strict criteria and the WHO guidelines. All thestudies (n=10) using the 5 and 14% normal sperm morphology thresholds(strict criteria) produced positive predictive values for IVFsuccess. In the prediction of pregnancy, 82% (9/11) and 75%(6/8) of the studies produced positive predictive values whenusing the 5% and 14% thresholds respectively. Aggregating thedata produced around the 5% normal sperm morphology threshold(strict criteria), the overall fertilization rates were 59.3%(1979/3337; per oocyte) for the 4% group and 77.6% (10345/13327;per oocyte) for the >4% group, and the overall pregnancyrates were 15.2% (60/395; per cycle) and 26.0% (355/1368; percycle) respectively. The no-transfer rates across the 5% thresholdwere 24.0% (86/359; per cycle) in the 4% group compared to 7.4%(80/1088; per cycle) in the >4% group. The inclusion of anaccurately evaluated normal sperm morphology count as an integralpart of the standard semen analysis makes this analysis stillthe most cost-effective means of evaluating the male factor.
