Eye injuries caused by vesicatory insects

Ocular injuries by vesicatory insects appear exceptional and the authors have not found any reports in the literature. Cantharidine, with toxicity comparable to that of mustard gas, can be present in many species of coleoptera. It results in progressive corneal necrosis ending in ocular perforation in 30 days. The necrotic process persists with long duration because this material is not broken down. It provokes deep ocular injuries (cristalline lens). The inflammatory reaction is severe with acute refractory hypertension. There exists no antidote, only prevention is useful. Emergency penetrating keratoplasty with anterior chamber lavage should help eliminate the toxin. In daily practice, the authors observe similar but less serious injuries; they think that they could be due to dust rich in vesicatory insect debris or their secretions.     

Evaluation of student participation in the management of the activities of the medical service of the Centre des Oeuvres Universitaires of Dakar (COUD]

The students of Centre des Oeuvres Universitaires de Dakar (COUD) do not seem to participate to the management of their own health status in spite of their financial participation in some services. The aim of this study is to evaluate the students's participation in their own health status. The results obtained from documents and archives, COUD'S responsible and student's opinion have shown a financial participation of 8% from the COUD medical service budget. The students wish to participation actively to the management of the medical service while COUD's responsible have opposite opinion. For an efficiency management of their own health status, students must necessary participate.     

Surveillance of Staphylococcus aureus in veterinary teaching hospitals

Staphylococcus aureus isolates (n = 70) from 65 patients (36 canine, 18 equine, 7 bovine, 2 avian, and 2 feline) at seven veterinary teaching hospitals in the United States were studied. The majority of patients (83%) with an S. aureus infection were canine and equine, but this may have reflected a sample bias based on clinic case loads and diagnostic lab submissions at the participating institutions. Fourteen percent of patients with an S. aureus infection were infected with a methicillin-resistant S. aureus (MRSA) isolate. Six of seven institutions had at least one MRSA infection during the study. Pulsed-field gel electrophoresis on 63 of the 70 isolates yielded 58 unique strains of S. aureus. None of the strain types of the MRSA isolates matched each other or the type of any other S. aureus isolate. The proportions of patients infected with an MRSA isolate were not significantly different between institutions or animal species (P > or = 0.222). Methicillin-resistant S. aureus isolates in this study seemed to be community acquired rather than hospital acquired.     

Developmental aspects of complement components in the newborn. The presence of complement components and C3 proactivator (properdin factor B) in human colostrum

A deficiency of all nine complement (C) components in cord sera relative to maternal serum levels was demonstrated. At 4 days of age, C1q (measured immunochemically), C1, C2, C4 and C7 levels were increased markedly to maternal levels. C3 was the only C component which exhibited no significant change between birth and at 4 days of age. A marked deficiency of serum levels of C8 and particularly of C9 was evident at birth.

No haemolytic C was demonstrable in the colostrum from which lipids were previously removed. Functional C3 was measurable by immune adherence with EAC142 intermediate sheep cells. Functional C3PA using cobra venom-induced lysis of unsensitized guinea-pig erythrocytes was also present. Substantial amounts of C3, C4 and C3PA determined immunochemically were found at 24 hr after birth with rapidly decreasing levels at 48 and 72 hr. C1q and C5 were absent. No differences of C components were evident in sera between bottle and breast-fed infants for any of the nine components studied.

     

WISC-R Verbal/Performance Discrepancies in Pediatric Cancer Patients

Intelligence testing was completed on 38 newly diagnosed pediatriconcology patients and 29 hemophilia patients between 6 and I7years of age. A low Verbal/high Performance intelligence testpattern was displayed by 39% of the oncology patients as comparedto an expected frequency of 12/14% in the hemophilia controls.Increased amounts of prednisone, vincristine, and number ofdays between diagnosis and intelligence testing correlated withthe Verbal-Performance (V-P) discrepancy scores in the oncologypatients. These findings and previous studies suggest the needfor monitoring the intellectual, emotional, linguistic, andneuropsychological status of pediatric oncology patients beginningat the time of diagnosis.     

Novel and recurrent mutations in the C-terminal domain of COMP cluster in two distinct regions and result in a spectrum of phenotypes within the pseudoachondroplasia -- multiple epiphyseal dysplasia disease group

Pseudoachondroplasia (PSACH) and some forms of multiple epiphyseal dysplasia (MED) result from mutations in the gene encoding cartilage oligomeric matrix protein (COMP). COMP is a large pentameric glycoprotein found predominantly in the extracellular matrix of cartilage, tendon, and ligament. As a modular protein, it is composed of a coiled-coil domain, four type II (T2) repeats, eight type III (T3) repeats, and a large globular C-terminal domain (CTD). The majority (>85%) of COMP mutations causing PSACH or MED are found in the exons encoding the T3 repeats, and the disease mechanism has been characterised in detail. Much less is known about disease-causing mutations in the CTD; in 10 years only seven mutations have been identified. In this study, we describe eight novel and two recurrent mutations that we have recently identified in patients with PSACH or MED. Interestingly, these mutations result in a spectrum of disease, ranging from mild MED to severe PSACH. Mapping of all known COMP CTD mutations on a three-dimensional model of the C-terminal domain shows that the CTD mutations cluster in two distinct regions. These regions are probably important in stabilising the T3-CTD structure and mediating intra- or intermolecular interactions.
