Testicular feminization syndrome. Four case reports with a brief review of the literature

Four cases of testicular feminization syndrome in Ethiopian patients are described. All four patients had normal female breasts, scanty pubic and axillary hair and absent internal genital organs. Three had bilateral inguinal or labial masses. The main features of their clinical presentation and histological studies are briefly discussed with a review of the literature.     

A comparison of the potency of the oxime HLö-7 and currently used oximes (HI-6, pralidoxime, obidoxime) to reactivate nerve agent-inhibited rat brain acetylcholinesterase by in vitro methods

(1) The efficacy of the oxime HL?7 and currently used oximes (pralidoxime, obidoxime, HI-6) to reactivate acetylcholinesterase inhibited by various nerve agents (sarin, tabun, cyclosarin, VX) was tested by in vitro methods. (2) Both H oximes (HL?-7, HI-6) were found to be more efficacious reactivators of sarin and VX-inhibited acetylcholinesterase than pralidoxime and obidoxime. On the other hand, their potency to reactivate tabun-inhibited acetylcholinesterase is very low and does not reach the reactivating efficacy of obidoxime. In the case of cyclosarin, the oxime HI-6 was only found to be able to sufficiently reactivate cyclosarin-inhibited acetylcholinesterase in vitro. (3) Thus, the oxime HL?-7 does not seem to be more efficacious reactivator of nerve agent-inhibited acetylcholinesterase than HI-6 according to in vitro evaluation of their reactivation potency and, therefore, it is not more suitable to be introduced for antidotal treatment of nerve agent-exposed people than HI-6.

Physical Violence and Associated Factors among Women of Reproductive Age in Gedeo Zone,Southern Ethiopia

BackgroundPhysical violence against women of reproductive age is a significant public health problem worldwide. This study aimed to assess physical violence and associated factors among women of reproductive age.MethodA community-based cross-sectional study design was implemented from August 1 to September 30, 2018, including women of reproductive age in Gedeo Zone Southern Ethiopia. A stratified, two-stage cluster sampling technique was used. Finally, the study population was selected from the respective source population using a simple random sampling technique. Data were checked, coded, and entered Epi data version 3.1 and exported to SPSS version 20 for analysis. The wealth index was computed using the principal component analysis. Bivariate and multivariable analyses were computed to identify the determinants of physical violence among women of reproductive age.ResultsExperiencing at least one type of physical violence among women of reproductive age was 14.7% (95%CI: 11.7, 17.4). Study participants whose spouse had any habit (AOR: 3.56; 95%CI: 1.75, 7.25) and whose spouse had watched pornography counterpart ((AOR: 1.58; 95%CI: 1.02, 3.17) had significantly higher odds of experiencing physical violence among women of reproductive age. Spouses had any habit like alcohol drinking, chat chewing, cigarette smoking, and seeing pornography significantly increased physical violence among reproductive-age women. Therefore, the responsible stakeholders should work on the means to the spouse can alleviate any form of habit like alcohol drinking, chat chewing, cigarette smoking, and seeing pornography could decrease physical violence in women of reproductive age.     

Neuroprotective effects of antidotes in soman-poisoned rats

1. The neuroprotective effects of antidotes (atropine, obidoxime/atropine mixture, HI-6/atropine mixture) on rats poisoned with soman at a sublethal dose (48 micrograms/kg i.m.; 60% of LD50 value) were studied. The neurotoxicity was monitored using a functional observational battery (FOB) and an automatic measurement of motor activity. The neurotoxicity of soman was monitored at 24 h and 7 d following soman poisoning. 2. The results indicate that atropine alone and the oxime HI-6 in combination with atropine seem to be effective antidotal treatment for the elimination of soman-induced neurotoxicity in the case of sublethal poisonings. 3. On the other hand, the combination of obidoxime with atropine appears to be practically ineffective in diminishing neurotoxic soman-induced symptoms. 4. Dealing with neuroprotective effects of antidotes, the oxime HI-6 in combination with atropine seems to be more suitable antidotal mixture than obidoxime in combination with atropine even in the case of sublethal poisoning with nerve agents.     

Advanced Pediatric Neurosonography Techniques: Contrast‐Enhanced Ultrasonography,Elastography, and Beyond

Recent technical advances in neurosonography continue broadening the diagnostic utility, sensitivity, and specificity of ultrasound for detecting intracranial abnormalities bed side. The clinical and functional applications of neurosonography have significantly expanded since the 1980s when transcranial Doppler sonography first allowed anatomic and hemodynamic delineation of the intracranial vessels through the thin temporal skull. In the past few years, contrast‐enhanced ultrasonography, elastography, 3D/4D reconstruction tools, and high‐resolution microvessel imaging techniques have further enhanced the diagnostic significance of neurosonography. Given these advances, a thorough familiarity with these new techniques and devices is crucial for a successful clinical application allowing improved patient care. It is essential that future neurosonography studies compare these advanced techniques against the current “gold standard” computed tomography and magnetic resonance imaging to assure the accuracy of their diagnostic potential. This review will provide a comprehensive update on currently available advanced neurosonography techniques.     

Review of oximes in the antidotal treatment of poisoning by organophosphorus nerve agents

The cholinesterase-inhibiting organophosphorus compounds referred to as nerve agents (soman, sarin, tabun, GF agent, and VX) are particularly toxic and are considered to be among the most dangerous chemical warfare agents. Included in antidotal medical countermeasures are oximes to reactivate the inhibited cholinesterase. Much experimental work has been done to better understand the properties of the oxime antidotal candidates including the currently available pralidoxime and obidoxime, the H oximes HI-6 and Hl?-7, and methoxime. There is no single, broad-spectrum oxime suitablefor the antidotal treatment of poisoning with all organophosphorus agents. If more than one oxime is available, the choice depends primarily on the identity of the responsible organophosphorus compound. The H oximes appear to be very promising antidotes against nerve agents because they are able to protect experimental animals from toxic effects and improve survival of animals poisoned with supralethal doses. They appear more effective against nerve agent poisoning than the currently used oximes pralidoxime and obidoxime, especially in the case of soman poisoning. On the other hand, pralidoxime and especially obidoxime seem sufficiently effective to treat poisonings with organophosphorus insecticides that have relatively less toxicity than nerve agents.
