The Black Mango fault is a structural discontinuity that transforms motion between two segments of the active Himalayan Frontal Thrust (HFT) in northwestern India. The Black Mango fault displays evidence of two large surface rupture earthquakes during the past 650 years, subsequent to 1294 A.D. and 1423 A.D., and possi…

In this work the authors have examined through the survey, the prevalence of smoking, alcohol consumption and drug abuse among the school children and youth. Subjects in this research were 208 pupils in Primary school and 232 pupils in Secondary school. It has been found that in the group of Primary school children 0.9…

Ice cores that were recovered from the summit of Sajama mountain in Bolivia provide carbon-14-dated tropical records and extend to the Late Glacial Stage (LGS). Oxygen isotopic ratios of the ice decreased 5.4 per mil between the early Holocene and the Last Glacial Maximum, which is consistent with values from other ice…

Under analysis was the material of the department of urgent and consultation medical aid (sanitary aviation) for the last 20 years. It was found that under conditions of surgical departments of central regional hospitals multiple relaparotomies made up 12.5% of all reoperations. It was shown that results of the multipl…

The authors report their experience in evaluating abdominal aorta aneurysms (AAA) by ultrasound examination. The incidence of this kind of disease is growing up in the last years and an earlier diagnosis increases the surviving possibilities of the patient affected, above all if symptomless, leading to a correct treatm…

Most surgical techniques for reconstruction of the aortic valve, although described a long time ago, are now feasible with satisfactory results. The general surgical principles for successful reconstruction, and the operative techniques of annuloplasty, commissurotomy, free edge resuspension, unrolling and thinning, an…

This report describes 11 cases of Plasmodium vivax infection of Colombian origin that relapsed 49-166 days following treatment with chloroquine or amodiquine (1.5 g in 3 days) plus primaquine (15 mg daily for 14 days) a regimen widely used to effect radical cure of infections with this parasite. Relapses occurred under…

Fourteen boys, aged 2 to 13, have been examined in the last six years for blood spotting from urethra between voidings, rarely associated with some degree of dysuria. No anomaly was seen on IVP, except in two cases which showed mild stenosis of the posterior urethra. Endoscopic evaluation was completely negative in 5 c…

In four of the five autosomal dominant porphyrias four different partial enzymatic defects of the porphyrin biosynthetic pathway have been discovered in the last few years. With the exception of protoporphyria, the residual enzymatic activity in carriers of these defects is approximately equal to 50% of that found in c…

Within the last years 70 transduodenal sphincterotomies at stringent indication have been carried out at the Department of Surgery of the RWTH Aachen. This means 9.2% of all operations caused by cholelithiasis. The lethality was 4.2%. The following postoperative complications where stated: a) the bleeding from the divi…

The authors carried out a clinical, chemical and medico-social study of an endemic focus in the Argeş Valley. Iodine deficiency and partially water hardness constitute the main goitrogenic factors. Owing to the curative-prophylactic means, the goitre frequency substantially decreased in school children (from 98.5…

BACKGROUND: While studies from other countries have shown an excess mortality in diabetic individuals when compared with the general population, comparable long-term data is not available for Switzerland. AIMS: To assess gender-specific cardiovascular and non-cardiovascular mortality of patients with type 1 and type 2…

OBJECTIVES: Fournier's gangrene is a devastating infection, which includes the genital, perineal and/or perianal regions. It is potentially fatal, and affects any age and gender. The severity index for Fournier's gangrene has been described; it is useful for evaluating the prognosis of these patients. Our goal is to re…

Atomic force microscopes (AFM) or low-noise in-house dedicated devices can highlight nanomotion oscillations. The method consists of attaching the organism of interest onto a silicon-based sensor and following its nano-scale motion as a function of time. The nanometric scale oscillations exerted by biological specimens…

In response to an increase in the incidence of whooping cough in recent years, the Basque Country established a vaccination programme for pregnant women in the last trimester of the pregnancy seeking to protect young infants, a population that is at high risk of developing severe whooping cough. In the present study, b…

Urinary analysis is one of the most requested tests in the clinical laboratory. This test includes the physical, chemical and microscopic analysis of urine. This last one allows for the observation of urinary sediment (US) in search of formed elements (cellular cast, leukocytes, etc.), with different diagnostic uses. U…

A key focus of evolutionary developmental biology (evo-devo) in recent years has been to elucidate the evolution of developmental mechanisms as a means of reconstructing the hypothetical last common ancestors of various clades. Prominent among such reconstructions have been proposals as to the nature of the mysterious…

The association between nasal snuff and malignancy is not well established. There is epidemiological evidence suggesting that oral tobacco when mixed with lime and betel leaves causes oral cancer in the Indian subcontinent. Similarly, snuff spiced with dried aloe has been reported to cause upper jaw malignancies in the…

Aplastic anemia encompasses a heterogeneous group of diseases with distinct pathophysiologies and a common clinical endpoint of marrow failure. Patients with severe aplastic anemia can be treated with immunosuppressive therapy (IST) or hematopoietic stem cell transplantation (HSCT). Over the last 30 years, advances in…

Classification of odontogenic tumours is an academic exercise that has developed over the last 150 years. It was not until 1971 when a 5-year collaborated effort, organized by the World Health Organization (WHO), resulted in the first consensus on taxonomy of odontogenic tumours. The appearance of this first authoritat…
