Ultrasound diagnosis of femoral nerve neurostenalgia : a cause of hip pain in a young adult

Femoral neurostenalgia is a compressive neuropathy which is an uncommon cause of hip pain in active young adults. Compression of the nerve can cause debilitating pain and an inability to walk. Correct clinical diagnosis and correct treatment can result in complete relief of symptoms. We present a case of a young female with a spontaneous acute onset of severe hip pain for ten months. After seeing several specialists and having undergone numerous special investigations, femoral nerve compression by the iliopsoas was demonstrated on ultrasound, but only confirmed during surgery for a suspected femoral hernia. After decompression of the nerve the patient was completely pain free.http://www.charpublications.co.za/C_JournalsORTH.aspay201

Comparison of radiation damage in silicon induced by proton and neutron irradiation

The subject of radiation damage to Si detectors induced by 24-GeV/c protons and nuclear reactor neutrons has been studied. Detectors fabricated on single-crystal silicon enriched with various impurities have been tested. Significant differences in electrically active defects have been found between the various types of material. The results of the study suggest for the first time that the widely used nonionizing energy loss (NIEL) factors are insufficient for normalization of the electrically active damage in case of oxygen- and carbon-enriched silicon detectors. It has been found that a deliberate introduction of impurities into the semiconductor can affect the radiation hardness of silicon detectors. (16 refs)

Project status of the CMS tracker optical links

The development phase of the optical data transfer system for the CMS tracker is now complete. This paper presents the project status and reviews the preparation for production. In particular, it focuses on the results of the market surveys for front-end components, and on the performance evaluation of a close-to-final readout chain. I

Efficacy of fipronil/(S)-methoprene/eprinomectin/praziquantel (Broadline®) against Thelazia callipaeda in naturally infected cats

Background: The present clinical field trial was conducted to assess the efficacy of a broad-spectrum parasiticide spot-on formulation containing eprinomectin (Broadline®) against Thelazia callipaeda eyeworm in naturally infected cats. Methods: Fifteen privately owned cats harboring at least one live adult T. callipaeda were included in the study. Cats were randomly allocated to an untreated control group of seven cats or to a Broadline®-treated group of eight cats. Cats were treated on Day 0; ocular examinations were performed at inclusion and on Days 7 and 14; eyeworms were recovered and counted on Day 14. The primary efficacy assessment was based on group comparison of number of T. callipaeda on Day 14. Results: Seven days after treatment, six of eight treated cats were negative for eyeworm infection per visual examination, and on Day 14 no eyeworms were found in the treated cats while the seven untreated cats were still infected (geometric mean: 1.97). All cats had inflammatory ocular signs at inclusion; on Day 14, five of eight treated cats had recovered while all untreated control cats were still symptomatic. All collected parasites were confirmed to be T. callipaeda by morphology and molecular characterization. Conclusions: A single treatment with Broadline® provided 100% efficacy against feline thelaziosis and improved related ocular inflammation signs.
