Open, Observational, Single-Arm, Multicenter Study Assessing the Effectiveness of a Dietary Supplement Containing Hydrolyzed Collagen, Chondroitin Sulfate, and Glucosamine for Osteoarthritis Pain Reduction.

Osteoarthritis (OA) is an age-related degenerative joint disease with a great impact on patients' well-being and quality of life. This is an observational, open, single-arm multicenter study aimed to evaluate the effectiveness of a nutritional supplement in patients with knee and/or hip OA. A total of 186 patients were recruited from Spanish centers and received a supplement containing hydrolyzed collagen (3000 mg), chondroitin sulfate (800 mg), glucosamine sulfate (700 mg), turmeric extract (250 mg) and devil's claw (150 mg), once daily during 6 months.

[Mosaic trisomy 18. Series of cases].

Trisomy 18 syndrome (T18) is a clinical and genetic disorder, which has a full extra chromosome 18 in each cell, variant that is called free trisomy. In addition, it can occur in partial and mosaic form. It is characterized by intrauterine growth restriction, psychomotor and mental retardation, characteristic craniofacial findings, congenital heart disease, hypoplastic pelvis, clenched hand and rocker-bottom foot, among others.

Fast-track recovery technique applied to primary total hip and knee replacement surgery. Analysis of costs and complications.

Purpose: To determine the cost reduction and complication rates of using an enhanced recovery pathway (Fast-track) when compared to traditional recovery in primary total hip replacement (THR) and total knee replacement (TKR), as well as to determine if there were significant differences in complication rates.

Material And Methods: Retrospective review of 100 primary total arthroplasties using the Fast-track recovery system and another 100 using conventional recovery. Gender, Charlston comorbidity index, ASA score, length of stay and early complications were measured, as well in-hospital complications and those in the first six months, re-admissions and transfusion rates.

[Gastroduodenitis and Helicobacter pylori in uremic patients].

We studied 26 patients (p) with end stage renal failure (RF) and 26 healthy volunteers (HV) to investigate the prevalence of Helicobacter pylori (Hp) and its relation with chronic gastritis (CG) and chronic duodenitis (CD). We analyzed 312 gastric and duodenal mucosal biopsies stained with H & E and Giemsa. Categorical data were assessed by the X2 and Fisher's exact test.

[Technique of cellular clot-block for the processing of material obtained by puncture-aspiration with fine needle].

A method is described for the processing of material obtained by fine needle aspiration. During the procedure, continuous aspiration, movement and rotation of the needle is performed in order to obtain at least 2 ml of material and blood. Samples are processed immediately for cytology and the rest of the material is left in the syringe until it coagulates.
