Just like in other areas of the medical science antibiotics are widely used in oral surgery, too. The aim of the present study is to give a retrospective survey of the use of antibiotics between the years 1989-1998 in the Section of Oral surgery of the Stomatological Department of the Medical and Health Science Centre…

INTRODUCTION: This study is conducted to evaluate the long-term outcomes, including effectiveness and complications, of artificial urinary sphincter (AUS) implantation in men with primarily stress urinary incontinence. MATERIALS AND METHODS: Consecutive patients with complete data sets and a continuous follow-up with…

PURPOSE: The aim of this study was to retrospectively evaluate midterm results of renal radiofrequency (RF) ablation compared to the results after nephrectomy in patients with T1a renal cell carcinoma (RCC). MATERIALS AND METHODS: A total of 115 patients with a single RCC measuring </=4 cm (T1a) were included; 51 pati…

Shale oil and gas exploitation by hydraulic fracturing experienced a strong development worldwide over the last years, accompanied by a substantial increase of related induced seismicity, either consequence of fracturing or wastewater injection. In Europe, unconventional hydrocarbon resources remain underdeveloped and…

PURPOSE: To present immediate results of percutaneous transluminal coronary angioplasty (PTCA) with the use of last generation catheter devices. METHODS: 74 patients underwent PTCA mean age 55 years the majority of them with disease of one vessel (92%) and good left ventricular function (88%). There was a total of 80…

The conventional surgical treatment of isolated critical stenosis of the left main coronary artery restores a less physiologic perfusion of the myocardium, leads to occlusion of the left coronary ostium, and consumes an appreciable length of bypass material. Starting in June 1985, 23 surgical angioplasties have been pe…

Various studies have shown an increase in utilization of dental services among the elderly in the last three decades. This study aimed at evaluating utilization rate of non-institutionalized geriatric population in Jerusalem and determining reasons for non-utilization. To eliminate the factor of accessibility of servic…

tRNA fragments (tRNA derived fragments or tRFs) are small single stranded RNA molecules derived from pre-tRNAs and mature tRNAs. tRFs have been known for a number of years, but previously they were believed to be not important products of tRNA degradation. tRFs can be unique, like tRF-1&#xa0;s, or redundant, like tRF-3…

The study was undertaken in response to local concerns of a rising number of community-acquired methicillin-resistant Staphylococcus aureus (MRSA) infections. All patients resident in the community in Essex at the time of diagnosis with a first isolate of MRSA between 1994 and 2001 identified by the diagnostic microbio…

The Hamburg Institute of Forensic Medicine analysed 388 deaths of homeless people between 1990 and 1998 considering demographic data, post-mortem results and autopsy findings. The manner of death was either unnatural or unascertained; the autopsy rate amounted to 43.8%. The results confirm the observation discussed in…

Since the inception of the National Mycobacterial Surveillance System (NMSS) in 1991, annual crude notification rates for tuberculosis (TB) have remained stable at between 5 and 6 per 100,000 population. In 1997, there was a total of 1,001 TB notifications in Australia, of which 954 were new TB cases and 47 relapses. T…

According to a prospective study performed in 1993, Chile had 14,400 active physicians (excluding those over 70 years of age) and a physician/inhabitant ratio of 1:960. The estimated projection for 1998 was of 16,244 physicians and a ratio of 1:921. However, during the present decade, the number of medical schools in C…

The authors report their experience of mechanical malfunctionings after placement of the AMS 800 artificial urinary sphincter. The aim of the study was to suggest outlines for the evaluation and management of these complications. From 1991 to 1998, 42 patients (39 men, 3 women with a mean age of 67.5 years) underwent a…

Thirty-one revisions for aseptic or septic loosening of knee arthroplasty have been performed between 1983 and 1995. In 18 cases we had loosening of uni- or bicondylar prosthesis and in 13 cases a tricompartmental revision arthroplasty. With an average of 53 months (1.5 to 13 years) after the last operation 21 patients…

We reviewed retrospectively 67 consecutive women with complicated stress incontinence who underwent a pubovaginal fascial sling procedure by a single surgeon. A detailed micturition questionnaire was completed at the last followup, which ranged from 1 to 8 years, with a mean of 3.5 years. Postoperatively, 82% of the wo…

During the last four years 12 Prolactin (PRL) secreting adenomas whose first clinical manifestation appeared before the age of 15 years have been studied. The first signs were a decreased growth rate and arrest of pubertal development in 4 girls and 2 boys in whom the adenoma occurred before or during puberty. In the o…

Colicin typing of 436 strains of Shigella sonnei isolated in Dallas during a 10-year period was performed to determine whether resistance to ampicillin was associated with a single strain or was widespread among all S. sonnei types. One hundred ninety-three strains collected during a period of eight and one-half years…

Although a screening program for gastric cancer, using barium X-ray examination, has been carried out widely in Japan for the past 3 decades, there is insufficient evidence to confirm its effectiveness in terms of reducing mortality. To evaluate the effectiveness of the screening, a population-based case-control study…

BACKGROUND: Single-center data on pediatric heart transplantation spanning long time frames is sparse. We attempted to analyze how risk profile and pediatric heart transplant survival outcomes at a large center changed over time. METHODS: We divided 320 pediatric heart transplants done at Stanford University between 1…

BACKGROUND: Despite restoration of fertility after kidney transplantation, the benefit is limited in female kidney recipients. Our objective is to determine the reasons for this discrepancy. METHODS: We evaluated 315 women who underwent kidney transplantation from 1983 to 2015 (a median of age at transplantation [10th…
