BACKGROUND: Thyroglossal duct cysts are in second place after goitre as a cause of anterior neck mass in paediatric age. The essentially clinical diagnosis is made on the basis of the observation of an asymptomatic mass, in most cases between the ages of 3 and 5. In this study we re-examined the cases of thyroglossal d…

UNLABELLED: In the last 2 years, we have performed combined pancreas-kidney transplantation in 38 Type I diabetics with nephropathy. The mean age of the recipient group was 35 years (range 24-51) with a mean duration of diabetes of 22 years (range 13-41). All patients received quadruple immunosuppression with OKT3 indu…

Over the course of the last 5 years, we have instituted peritoneal dialysis on 26 (7.7%) of 338 complex postoperative cardiac bypass cases. The mean age of dialysis patients was 0.64 +/- 0.75 years with a range of 0.1-2.5 years. The indications for the start of dialysis were oliguria (15 cases), fluid overload (three c…

Because of the increasing longevity of man, more elderly patients of abdominal aortic aneurysm are being considered for surgical treatment. It is the purpose of this report to provide the data based on analysis of 23 patients, 70 years of age or older, compared with 26 patients, under 70 years of age, seen at our insti…

Transplant kidneys face increased functional demands in comparison to physiological conditions, and glomerular hypertrophy (GH) appears to be a common compensatory mechanism. Adaptive GH could contribute to improved graft function, but a so-called "maladaptive" response may lead to shortened graft survival. We assessed…

AIM: To evaluate the long-term follow-up results of external dacryocystorhinostomy (Ex-DCR) and to assess the role of some factors in its success. PATIENTS AND METHODS: Between January 1990 and November 2002, 437 nasolacrimal systems of 387 patients were operated on and included in the study. The success rates were de…

A retrospective study was performed on 255 consecutive patients admitted to a single hospital from 1953-1983 with a follow-up of 100%. The number of proximal esophagogastric junction and fundus tumors increased significantly over the last 4 decades from 21% to 44% (p less than 0.001), accompanied by a significant decre…

Multicomponent reactions (MCRs) offer a highly useful and valuable strategy that can fulfill an important role in synthesizing complex polysubstituted compounds, by simplifying otherwise long sequences and increasing their efficiency. The total synthesis of selected natural products employing three-component reactions…

Last June, the stem cell community came together to celebrate the 20th anniversary of the International Society for Stem Cell Research (ISSCR), one of the leading organizations in the field. The hybrid event mixed a varied program filled with plenary talks, concurrent track sessions, poster presentations, exhibit booth…

IMPORTANCE: Laparoscopic sleeve gastrectomy for treatment of morbid obesity has increased substantially despite the lack of long-term results compared with laparoscopic Roux-en-Y gastric bypass. OBJECTIVE: To determine whether laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass are equivalent for…

BACKGROUND: Contemporary survival in unselected patients with heart failure and the population impact of newer therapies have not been widely studied. Therefore, we have documented case-fatality rates (CFRs) over a recent 10-year period. METHODS AND RESULTS: In Scotland, all hospitalizations and deaths are captured on…

OBJECTIVE: To study trends in injury mortality for low- and high-risk young children. DESIGN AND METHODS: For Tennessee children 0 to 4 years of age, we used birth certificates to obtain data on maternal education, age, and parity; these risk factors were used to classify children into low- and high-risk groups. The o…

Problems in myocardial revascularization for coronary impairment due to Kawasaki disease were assessed in five patients 1 to 4 years old. Each patient had significant stenosis or complete obstruction with aneurysm formation. There were no operative or late deaths in the follow-up period of 1 to 10 years after operation…

During the last 7 years semirigid intracorporeal penile prostheses were inserted in 36 spinal cord injury patients between 21 and 58 years old (average age 38.5 years). An operation was done 1 to 32 years after the initial injury (average 10 years). Surgical intervention was intended to provide an adequate body to the…

The growth pattern is reported of 16 patients with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency in whom therapy was started after the age of 3 years. Treatment was initiated at a mean chronological age (CA) of 4.7 years (range 3.0-7.2) and at a mean bone age (BA) of 10.4 years (range 10.2-13.2)…

PURPOSE: Nerve transfers to restore elbow flexion have been described for traumatic brachial plexus palsy in adults. Indications are less frequent in infants and the results are less published. METHODS: Ten patients with obstetrical brachial plexus palsy were operated on for lack of flexion against gravity with ulnar…

The aim of this case series was a clinical, histologic, and histomorphometric evaluation of calcium carbonate in sinus elevation procedures. Sinus augmentation was performed in the atrophic maxillae of 24 subjects using calcium carbonate. Six months after the regeneration procedures, 68 implants were placed and clinica…

UNLABELLED: Cable-wakeboarding has become more and more popular in the last years in Germany and worldwide as well. The mechanism, frequency and severity of injuries is still unclear and not described in the literature yet. Thus to compare the injuries of cable-wakeboarding with similar sports we decided to perform thi…
