Monitoring of blood lead levels (BLL) in children started in Hungary only in the 80's. A study on exposed areas of Budapest and Szolnok indicated a mean BLL higher than 20 micrograms/dl. Data from studies show a strong relationship between the BLLs of children and traffic. As a result of reduction of the lead content o…

Overlapping sphincter reconstruction for fecal incontinence due to perineal tears, trauma or iatrogenic injuries is the therapy of choice. If this technique fails repeatedly or more than half of the sphincter is destroyed, a gracilis muscle plasty is indicated. Incontinence caused by an ectropion must be treated by a s…

OBJECTIVE: Bartter syndrome and Gitelman syndrome are rare inherited tubulopathies characterized by hypokalemic, hypochloremic metabolic alkalosis. This study aimed to clarify the frequency of the phenotypic and genotypic subgroups, clinical features, long-term management, and prognosis of children diagnosed with Bartt…

INTRODUCTION: Postsurgical gastric atony occurs infrequently after gastric surgery. However, the symptoms are disabling and refractory to medical management. The only effective treatment is completion gastrectomy. A few studies have examined in detail the long-term results of this radical procedure. METHODS: From 1988…

This investigation, using a case-control analysis approach on an IUD data set from a less-developed country center, delineated four risk factors in patient characteristics that are associated with severe pain at interval IUD insertion. They are: higher education (greater than or equal to seven years), low-parity (1-2 l…

OBJECTIVE To estimate the prevalence of sexual initiation and contraceptive use at the last sexual intercourse of Brazilian adolescents, according to sociodemographic features. METHODS The data were obtained from the Study of Cardiovascular Risks in Adolescents (ERICA), a national school-based cross-sectional study. We…

Primary amoebic meningoencephalitis (PAM) caused by free-living amebae Naegleria fowleri is a rare and fatal condition. A fatal case of primary amoebic meningoencephalitis was diagnosed in a 5-month-old infant who presented with the history of decrease breast feeding, fever, vomiting, and abnormal body movements. Troph…

Photodynamic therapy (PDT) for the treatment of actinic keratosis has been shown to be effective and safe in large clinical trials published in the last 5 years. However, evidence has since emerged that raises questions or that introduces new issues, such as the management of field cancerization, fluorescence diagnosis…

Studies on epidemiology and survival of patients diagnosed of cutaneous melanoma in our country are few. We described epidemiological, clinical, histopathologic and survival characteristics of patients diagnosed of cutaneous melanoma at Hospital Gregorio Marañón of Madrid during ten years (1994-2003). The inc…

The results of laparoscopic adnexial cyst excision operations performed within the last 2.5 years in our clinic are reported. Thirty-three adnexial masses thought to be benign after gynaecological examination and ultrasonographic findings were treated. Laparoscopy was done in 32 cases but laparotomy had to be performed…

A clinical review of 461 patients with adenocarcinoma of the pancreas is presented. Seventy-nine percent of the group underwent laparotomy, including laparotomy and biopsy (n = 134), bypass procedures (n = 207), and radical resection (n = 24). The operative mortality following cholecystoenterostomy or choledochoenteros…

INTRODUCTION: Antifungal stewardship (AFS) programs are recognized to contribute to optimizing antifungal prescribing for treatment and prophylaxis. However, only a small number of such programs are implemented. Consequently, evidence on behavioral drivers and barriers of such programs and learnings from existing succe…

BACKGROUND: Meticulous haemostasis is one of the most important factors during microneurosurgical resection of brain arteriovenous malformation (AVM). Controlling major arterial feeders and draining veins with clips and bipolar coagulation are well-established techniques, while managing with bleeding from deep tiny ves…

BACKGROUND: Biomedical research has grown considerably in the last few decades, and the authorship characteristics of the dental literature as a whole and of its specialty fields has changed significantly. Unfortunately, the bibliometrics of the periodontal literature have not been thoroughly investigated. The aim of t…

Femoroacetabular impingement (FAI) may be considered as an important cause of hip pain among young patients. A new surgical technique using a mini open anterior Hueter approach with arthroscopic assistance was developed in our department in 1999. The goal of our study was to evaluate the midterm clinical results and th…

PURPOSE: To investigate longevity and reasons for failure of Class II posterior composite restorations (PCRs) placed with or without a lining of glass-ionomer cement. MATERIALS AND METHODS: Four hundred fifty-eight Class II PCR placed in 248 patients (110 male, 138 female, age 18 to 80) by two dentists in a general pr…

An online survey of 528 people who lost someone close to them in the last 5 years was used to test associations between having final conversations (FCs) and depression. The direct effect was nonsignificant, but there were two significant moderation effects. Time since bereavement moderated the FC-depression rela…

Tip-enhanced Raman spectroscopy (TERS) has experienced tremendous growth in the last 5 years. Specifically, TER imaging has provided invaluable insight into the spatial distribution and properties of chemical species on a surface with spatial resolution that is otherwise unattainable by any other analytical method. Add…

Fluorescence imaging microscopes and fluorescent reagents have both evolved greatly in the past 10 years. Sensitive imaging cameras developed over the last decade allow detection of fluorescence signals from even a single fluorescent tag on a protein. At the same time, numerous antibody markers for growth control prote…

In 80 to 90% of the cases of partial or complete rupture of the membranous urethra, early en-to-end urethroplasy is successful in re-establishing the urethra. Secondary or delayed treatment of urethral injuries is required in unsuccessful cases or when a surgical procedure cannot be performed within the first 10 days f…
