Background: Nasolacrimal duct obstruction is usually treated using endoscopic or external dacryocystorhinostomy (DCR). The anatomic outcomes of both the endoscopic and external approaches are considered excellent. However, anatomic success does not translate into patient satisfaction.

Objective: Foot impairments are related to reduced mobility and participation restrictions in daily activities in patients with established rheumatoid arthritis (RA). The new biologic medications are effective and reduce disease activity, but not disability to the same extent. Foot impairments are assumed to be related to participation restrictions also in patients with early RA, diagnosed after the introduction of biologic medications.

Our results highlight the importance of preventing reinfection after eradication, through public health initiatives, and possibly treatment of family members. They indicate difficulties for vaccine development, especially therapeutic vaccines.

Method Out of the 454 patients that were recruited into the Swedish early RA project "TIRA" the 373 patients (67% women) that remained at 12 months follow-up are reported here. Disease activity 28 joint score (DAS-28), disability (Health Assessment Questionnaire = HAQ) and pain (VAS) were recorded at inclusion and after 3 (M3), 6 (M6) and 12 (M12) months.

The objective of the study was to explore emotions related to participation restrictions by patients with early RA. In this study, 48 patients with early RA, aged 20-63 years, were interviewed about participation restrictions using the critical incident technique.

Here we investigated the effects of Gsx on emotional reactivity in rats and explored the underlying neurobiological mechanisms. Gsx- and sham-operated rats were exposed to behavioural tests that explore anxiety- and depression-like behaviour (open field, black and white box, elevated plus maze, social interaction, forced swim) as well as memory (object recognition).

Transplantation of bone marrow expressing beta galactosidase into a wild-type mouse, followed by surgical esophagojejunostomy, allowed tracking of BMDCs into the surgical anastomosis and resulting Barrett's metaplasia. Human tissue from a male patient who had been transplanted with female bone marrow and later developed esophageal adenocarcinoma allowed us to tract donor-derived cells into the tumor.

The current standard for bariatric surgery is gastric bypass. There are common beliefs that gastric bypass induces body weight loss because of a reduced food intake and that high-fat diet induces overweight and obesity because of overnutrition.

New diagnostic methods have been introduced and in Australia, the recommended therapy choices in cases of penicillin allergy and for second line treatment are only accessible through the Therapeutic Goods Administration Special Access Scheme.
Objective: The article aims to update general practitioners on recommendations for testing and treating H.
Histamine in the rat stomach resides in enterochromaffin-like (ECL) cells and mast cells. The ECL cells are peptide-hormone-producing endocrine cells known to release histamine and chromogranin-A-derived peptides (such as pancreastatin) in response to gastrin. Ischemia (induced by clamping of the celiac artery or by gastric submucosal microinfusion of the vasoconstrictor endothelin) mobilizes large amounts of ECL-cell histamine in a burst-like manner.

Gastric hormones have been thought to play a role in the regulation of food intake and body weight. The aim of the present study was to analyze feeding behavior after total gastrectomy (Gx) or GB in rats.

We have morphologically characterized the cells that produce obestatin and ghrelin in new-born and adult Sprague-Dawley rats that were freely fed, fasted, or subjected to gastric bypass surgery or reserpine treatment. Tissue samples collected from the gastrointestinal tract and pancreas were examined by double-immunofluorescence staining, immunoelectron microscopy, and conventional electron microscopy.
View Article and Find Full Text PDFWe investigated whether ghrelin depletion (by gastrectomy surgery) and/or treatment/replacement with the gastric hormone ghrelin alters the expression of key hypothalamic genes involved in energy balance, in a manner consistent with ghrelin's pro-obesity effects. At 2 weeks after surgery mice were treated with ghrelin (12 nmol/mouse/day, sc) or vehicle for 8 weeks. Gastrectomy had little effect on the expression of these genes, with the exception of NPY mRNA in the arcuate nucleus that was increased.

We report 1-year follow-up results after micro-gastric bypass in rats. Micro-gastric bypass was performed by anastomosis of the esophagus and the proximal jejunum.
View Article and Find Full Text PDFBackground: The rationale for bariatric surgery is to reduce food intake by gastric restriction and/or malabsorption by intestinal bypass. Unlike ghrelin, gastrin is released in response to food intake. Here we studied the possible role of gastrin in the reduction of body weight after gastric bypass surgery.

Such augmentations have mostly been performed using autogenous bone blocks secured to the buccal surface. An alternative to autogenous bone may be bovine hydroxyapatite (Bio-Oss, Geistlich Pharma AG, Wolhusen, Switzerland) or other bone substitutes.
View Article and Find Full Text PDFA referral letter is an important carrier of information, and it is important that it contains what both the recipient and the referrers expect. Based on the concept of perceived quality of service, 126 consecutive referrals from the General Dental Service (GDS) and their associated replies from the Department of Oral Radiology (OR) were mutually evaluated. OR judged that necessary information about the patient was specified in over 80% of the cases, and that information pertinent to the issue and the proposed examination was included in over 90% of the cases.

Bone mineral density (BMD) of the hip was measured by dual energy X-ray absorptiometry.

Methods: Sixty-three subjects, 60 women and 3 men, participated in the study; 21 1 degree SS patients were compared with age-matched and gender-matched groups of TMD subjects and controls. Patients were examined according to the Research Diagnostic Criteria for Temporomandibular Disorders.
Observer performance in the assessment of the periapical pathology from panoramic and periapical radiography was examined. Five endodontists, five general practitioners and five oral radiologists were asked to assess the periapical status of 117 teeth. The observers assessed the panoramic and periapical radiographs of the teeth, which were evenly distributed throughout the jaws with a 50% probability that either an osteolytic or sclerotic lesion was present.

Using well-defined clinical criteria, there were no false-positive findings of either reducing or non-reducing discs. On the other hand, a risk of false-negative diagnosis of non-reducing disc was apparent.
