The chemistry of metal carbene complexes has experienced an enormous development in the past decades. Despite this fact, the use of transition metals as catalysts in reactions involving group 6 Fischer carbene complexes was virtually neglected. Here, we describe how the reactivity of these compounds can be enhanced or…

Thirteen consecutive patients with thalamic deep brain stimulation (DBS) were examined serially for 3 to 5 years. Initially, all demonstrated at least 50% improvement in contralateral tremor. At last follow-up, three of eight patients with Parkinson disease no longer used DBS because tremor had markedly improved, and f…

Early complications after partial pancreatic resections and benign pancreatic tumours were analysed. 276 patients with pancreatic tumours were treated in the years 1979-1997. In 77 cases radical operation was performed. 65 patients underwent Whipple and 12--Traverso-Longmire pancreatoduodenectomy. Malignant tumour was…

Transplantation of organs has increased dramatically over the last 3 decades. The Australian National Liver Transplant Unit was established in 1985 at Royal Prince Alfred Hospital. Their first 5 years was reported in a paper in 1992 in which survival was defined as 'going home'. The study reported in this paper followe…

The epidemiology of the diabetic foot is still unknown because this heterogeneous pathologic condition is non uniformly classified and described. Lower limb peripheral vascular disease has a preferential distal location strongly associated with the classical factors of cardiovascular risk. Ulcers occur in 15% of diabet…

Two cases of gall-stone ileus during the past months have encouraged us to discuss the epidemiology, pathogenesis, diagnosis and therapy. This pathology is not as rare as one thinks and represents 23% of cases of mechanical ileus of the small intestine in patients over 65 years of age, thus being the third cause after…

Amongst sacrococcygeal tumors, teratoma is seen often while other histologic types are rare. It is apparent that the less obvious intrapelvic tumors can cause obstructive symptoms and are usually diagnosed late. Twenty cases of sacrococcygeal tumor, including 14 teratomas (9 benign, 5 malignant) and 6 others (3 benign,…

For the last 18 years 21,808 alpine skiing injuries have been treated at the hospital of Davos. There is a great decline in the incidence of lower leg fractures with a contrary development of knee ligament injuries. Today half of the lower leg injuries are knee injuries. To ameliorate the documentation of all patients…

Roux-en-Y reconstruction has been in use for several years as a reoperation for persistent esophagitis after fundoplication. The limited data in the literature appear to favour this approach. We have conducted a retrospective review of the records of 5 patients who have undergone this type of surgery for persistent ref…

With the advent of microvascular anastomosis it has become technically and practically feasible to replant amputated digits. In the last 5 years the achievements in this field of surgery have shown considerable improvement. Success is initially measured in terms of survival of the amputated digits but finally in terms…

Over the last 20 years a comprehensive paediatric nephrology service has been developed in Northern Ireland, based in the academic medical unit at the Royal Belfast Hospital for Sick Children (RBHSC). In the 15 years 1984-1998 a total of 77 renal transplants have taken place in patients aged 18 years and under. Initial…

We assess early clinical and radiographic results of a multicentric and prospective study of 485 Summit porous-coated stems implanted in 5 hospitals. Of the patients, 171 had a hydroxyapatite (HA) coating and 314 had non-HA porous-coated stems. The mean follow-up was 4.2 years (range 2.5-6 years). The median size of th…

BACKGROUND: Intervertebral spacers made of silicon nitride (SiN) are currently used in cervical and thoracolumbar fusion. While basic science data demonstrate several advantages of SiNover other biomaterials, large-scale clinical results on its safety and efficacy are lacking. This multicenter retrospective study exami…

AIMS: To estimate the switching rate and to identify factors that predict switch from non-insulin to insulin therapy in patients with type 2 diabetes using routinely collected data from a clinical information system at Isfahan Endocrine and Metabolism Research Centre, Iran. METHODS: During the mean (SD) follow-up peri…

PURPOSE: Aim of the study was to evaluate the results of tubularized incised plate (TIP) urethroplasty in distal and mid penile hypospadias repair. MATERIALS AND METHODS: In this retrospective study, we analyzed the medical records of 195 boys (mean age: 2.1 years, range: 0.5-13 years) with distal penile (n=170) or mi…

Various methods of periacetabular osteotomy have been described. Since 1990, we have performed rotational acetabular osteotomy through an Ollier lateral U transtrochanteric approach without massive bone graft. This study investigated whether our technique could provide relief from symptoms, whether postoperative hip ab…

OBJECTIVE: To assess, particularly in longitudinal studies, how close or far the food intakes of population groups are from a reference dietary pattern. DESIGN: Computation of an index, called the Mediterranean Adequacy Index (MAI), by dividing the sum of the percentage of total energy from typical Mediterranean food…

Scientific epidemiological studies of dental health in children three years of age are relatively few in Sweden. The aim of this study was to describe the oral health of three-year-old children living in Sweden, with special reference to immigration and failure to attend health examinations. All of 671 children request…

BACKGROUND: Dislocation of an artificial intraocular lens (IOL) into the vitreous is a rare complication in cataract surgery. The removal of the IOL from the vitreous can be associated with various difficulties. As vitreal surgery in Latvia has been developed only during the last two years, patients with IOL dislocatio…

During the last 5 years, 640 patients had treatment to their port wine stains (PWS) with a flashlamp-pumped pulsed dye laser. One hundred and fifty-six patients have been discharged for varying reasons, of which 59 (38%) achieved excellent (at least 75%) lightening of their birthmark. Of the remaining patients, those w…
