The first child is on high doses of prednisone and also needs blood transfusion every 6 weeks. The second child is on 5 mg pred…

During the last few decades there has been a steady rise of the incidence of upper urinary tract stones in the industrialized countries. Dietary factors, mainly an increased consumption of animal protein, probably explain part of this dramatic change. Little is, however, known how other components of the altered life s…

A KAP (knowledge, attitude and practice) survey was conducted among 500 fertile Hausa women of northern Nigeria aged 15-44 years to test their understanding about family planning and reproductive biology. Three hundred and fifty-six women (71.2%) were still not satisfied with their family size and only 185 women (37%)…

Of 296 occult breast cancers diagnosed at Kaiser-Permanente Medical Center, Los Angeles, in the last ten years, 80 were classified as minimal and 167 as nonminimal. Minimal cancers were intraductal, lobular in situ, or invasive and 0.5 cm or less in diameter. In the occult-minimal group, no woman had axillary node meta…

Cases of acquired methemoglobinemia have been identified with increasing frequency in Los Angeles during the last several years. Among 18 patients, both infants and adults, the most commonly incriminated agent was silver nitrate used for topical antibacterial prophylaxis of burn wounds. One burned child died from overw…

The laboratories charged with dairy product control have had to determine the nitrates and nitrites especially for the examination of products in view of export. The use of nitrates is prohibited in France. Some E.E.C. countries however authorize its use in cheese-making. The L.C.H.A. has carried for the last several y…

BACKGROUND: Universal vaccination against hepatitis A virus (HAV) has been recommended for children because of the changing epidemiological pattern of HAV. Vaccination has also been advised for patients with chronic liver disease as HAV superinfection in these patients can result in severe or even fatal disease. In Ind…

The elateroid family Lycidae is known for limited dispersal propensity and high species-level endemism. The red net-winged beetle,(Herbst, 1874), differs from all relatives by the range comprising almost the entire Holarctic region. Based on a five-marker phylogeny and 67 barcode entries (' mtDNA) from the whole range,…

Among the many advances in local anesthesia of the hand, some of the most significant changes in the last 5 years have been the following: (1) the acceptance of safety of locally infiltrated epinephrine with lidocaine for hemostasis, which has removed the need for sedation, brachial plexus blocks, and general anesthesi…

Over the last 5 years, there has been a resumed interest in treating diabetes by transplantation, particularly islet transplantation. However, despite advances being reported in Canada and the US, replication in the UK has been much more difficult. At present there is still only one treatment that can consistently reve…

Over the last 5 years, 26 cancer patients developed pericardial effusion and were managed surgically with the creation of a subxiphoidal pericardial 'window'. The operation, in the majority of the cases was performed under local anaesthesia with adequate sedation. It was found to be safe and easy to perform. The operat…

The activity of thrombin is central to the processes of fibrin generation and platelet aggregation, which are inherent in thrombus formation. As a result of x-ray crystallographic studies over the last 5 years, we now have a firm knowledge of the structural basis for the specific interactions of thrombin with component…

The preoperative history and postoperative course of histologically verified 348 low-grade and 383 anaplastic astrocytomas have been reviewed. In 71.2 and 48.0% of patients epilepsy was the initial symptom of a suspected astrocytoma, and the history was longer than 3 years in 28.1 and 19.5% of cases, respectively. Befo…

Endothermal ablation of refluxing saphenous veins by Laser or radiofrequ…

A word's sentiment depends on the domain in which it is used. Computational social science research thus requires sentiment lexicons that are specific to the domains being studied. We combine domain-specific word embeddings with a label propagation framework to induce accurate domain-specific sentiment lexicons using s…

In recent years, the use of LC-MS technologies in the bioanlytical laboratory for quantitation of peptide/protein biomarkers and biotherapeutics has increased dramatically. The increased interest is due to the improvement in sensitivity of MS instruments over the last 5-10 years, as well as its proven ability to overco…

Overweight is associated with hypertension, but longitudinal studies on the effect of weight gain on blood pressure are relatively rare. Aim of this study was to investigate association of long-term overweight status as well as of becoming overweight with hypertension. Odds of hypertension in 2008 were calculated for 1…
