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…

11-13% of people suffer from the expressed obstruction of respiratory ways. For last 20 years death rate from chronic obstructive pulmonary disease (COPD) has been doubling each 5 years. Lung volume reduction surgery (LVRS) was performed in 27 patients with advanced diffuse emphysema from 2000 to 2008. Lateral thoracot…

The laparoscopic approach has been successfully used during the recent last years in pediatric surgery. We describe the first experience in Argentina using laparoscopic surgery in November 4th in 1996, for the treatment of a Hirschsprung disease case. We used the technique of Soave's modified by Georgenson. Details of…

OBJECTIVE: To examine the association between the use of intra uterine device (IUD) and the risk of actinomycosis in postmenopausal women. METHODS: We report a case of pelvic actinomycosis in a postmenopausal woman who was wearing an IUD for 14 years until 20 months after the beginning of menopause. In the last 5 year…

A case of Hallervorden-Spatz's disease is described in a thirteen-year-old patient, with typical case symptoms of pyramidalism, dystonia and regressive motor control, over the last four years. MRI provided a bilateral palidal image in 'tiger eye'. The possible appearance of early forms have been stressed, characterised…

OBJECTIVE: To examine the diagnosis and treatment of arteriovenous malformations in adults, because of the tendency of the condition to recur. DESIGN: Chart and literature review. SETTING: Three tertiary-care hospitals. PATIENTS: Twelve adults with diffuse arteriovenous malformations of the extremities. INTERVENTIO…

Esophagogastrostomy covered by tongue-like sero-muscular flap of gastric wall has already been performed in 1515 cases with esophageal cancer of middle or lower third segment over the last three years. All cases were of squamous cell carcinoma. The same anastomotic procedure was done in all cases by authors in differen…

The 1988 and 1991 strikes among nurses were motivated by claims concerning the status of the nursing profession, wages and working conditions. A study of working conditions was carried out from two samples: 1) a cohort of nurses (N = 571) recruited in 7 hospitals and followed up in 1980 (follow up rate: 85%) and in 199…

DHEA, a steroid precursor of androgens and estrogens has also an inhibitory effect on several enzymes, namely on 11 beta-hydroxylase, NADH oxidase and glucose 6-phosphate dehydrogenase. The latter is the rate limiting enzyme of the pentose phosphate cycle. This metabolic pathway provides the cells with extramitochondri…

During the period from 1968 to 1987, 50 children, adolescent and adult patients with acute disseminated tuberculosis of the lung were examined in a Republican Tuberculosis Hospital. It was concluded that the number of patients with that form of tuberculosis increased within the last 10 years and the classic form of acu…

A fifteen year old girl was admitted to our hospital with intractable back pain since the last 5 1/2 years. The provisional diagnosis was M. Bechterew. Our patient attended school sporadically during this period, her regular activity was severely curtailed, and she was under continuous Benzodiazepin medication. Analysi…

Five cases of acute spinal epidural abscess, all in male, two of them in children (6 and 7 years old) and the others in patients older than fifty years are reported. In four cases the pathology was related to skin infection and the staphylococcus was the main agent. All the patients had a severe infectious clinical pic…

About an experience of 7,757 investigations and after study of the published series in the literature, it appears the frequency of the accidents following vascular roentgenology has not really changed since ten years. -- 0,5% complications; 0,07% death in aortographies; -- 0,4% complications; 0,09% death in femoral art…

Over the last 5 years, there has been a dramatic increase in the use of extracorporeal membrane oxygenation (ECMO) in adult patients with severe respiratory or cardiac failure. This contrasts to the use of the technology in neonatal and paediatric intensive care units, where it has been regarded as a standard of c…

BACKGROUND: Cystinosis is a multisystemic disease resulting from cystine accumulation primarily in kidney and many other tissues. We intended to study the evolution of less commonly seen extrarenal complications of cystinosis in a group of patients who have periods without cysteamine treatment. METHODS: Gastrointestin…

INTRODUCTION: Life-threatening, space occupying, infarction develops in 10-15% of patients after middle cerebral artery infarction (MCAI). Though decompressive craniectomy (DC) is now standard of care in patients with non-dominant stroke, its role in dominant MCAI (DMCAI) is largely undefined. This may reflect the ethi…

BACKGROUND: The increasing use of biologic conduits and the advances in reparative aortic root procedures has increased the number of patients who may require reoperation on the aortic root. Although the primary operation yields excellent results with a low risk for morbidity and mortality, reoperation on the aortic ro…

PURPOSE: The American Urological Association (AUA) published clinical guidelines for the treatment of ureteral calculi in adults and note that up to 98% of stones less than 5 mm. in diameter will pass spontaneously. Ureteroscopy and shock wave lithotripsy were acceptable treatment choices for stones less than 10 mm. in…

OBJECTIVES: Until relatively recently southern Europe was regarded as having a medium to low multiple sclerosis prevalence, of about 20 or less per 100,000. However, recent studies in Sardinia, Sicily, continental Italy, Cyprus and Spain have yielded higher MS prevalence rates, between 32 and 102.6 per 100,000. We pres…
