Transcatheter Mitral Valve-in-Valve Implantation with the Balloon-Expandable Myval Device.

The vast majority of transcatheter valve-in-valve (ViV) mitral procedures have been reported with the SAPIEN family. We aimed to report the preliminary experience with the Myval balloon-expandable device in this setting. Multicenter retrospective study of high-risk surgical patients with mitral bioprosthesis degeneration undergoing transcatheter ViV implantation with Myval device.

Transcatheter aortic valve implantation with a novel pre-packaged self-expandable dry-tissue transcatheter aortic valve: a case report.

Background: Current commercially available transcatheter aortic valves are stored separately in a glutaraldehyde solution and mounted onto the delivery system by a technical expert during the transcatheter aortic valve implantation (TAVI) procedure. A pre-mounted dry-tissue valve that is crimped on a ready-to-use delivery system could simplify the procedure. The Vienna self-expanding transcatheter valve (P&F, GmbH, Wessling, Germany) is a novel ready-to-use pre-mounted dry-tissue transcatheter aortic valve.

Toxigenicity testing of clinical isolates of non-typhoidal salmonellae in Vero cell culture & Caenorhabditis elegans model.

The non-typhoidal salmonellae (NTS) are recognized agents of gastroenteritis worldwide. Some of the NTS do not produces cytotoxic changes in tissue culture and not much is known about the endotoxicity of the clinical isolates of NTS (mostly Salmonella enterica serotype Typhimurium and Salmonella enterica serotype Enteritidis). We examined the exotoxic (cytotoxin) and endotoxic activity of clinical isolates of NTS in two assay models namely Vero cell culture and the nematode, Caenorhabditis elegans.

Neonatal hypernatraemic dehydration and malnutrition associated with inadequate breastfeeding and elevated breast milk sodium.

The advantages of breastfeedng to both the mother and infant are well recognised. In rare instances if breasteding is inadequate or if the sodium content bast milk is high, malnutrition and hypernatraemia can result. A 15 days old exclusively breastfed baby presented with inadequate weight gain.

Alkathine shell, an innovative way of neck flexion after tracheoplasty.

Tracheal resection and end-to-end anastomosis is the treatment of choice for mature, isolated, segmental tracheal stenosis and tracheomalacia. Postoperatively, it is important to avoid tension at the anastomotic site. This is usually done by keeping the head in flexion, by a skin suture from chin to chest in the midline.

Studies on acid soluble thiols in the human gastric juice.

Human gastric juice was found to contain high levels of thiols as detected by reaction with dithionitrobenzoic acid (Ellman's reagent). Analysis of gastric juice for glutathione and cysteine, the known acid soluble thiols in biological system, by HPLC and calorimetric methods, indicated that they are absent in the gastric juice. Further studies on the nature of thiols in the gastric juice, by Sephadex G-25 gel filtration indicated the presence of both high and low molecular weight protein and peptide associated thiols.

A prospective study in a southern Indian hospital on the prescription of medication during the lying in period following childbirth.

The awareness of the inherent risks attached to medication use during pregnancy is increasing. There is, however, a paucity of available following childbirth. We have conducted a prospective study in women who gave birth in hospital with the objective of analysing the use of medication in this lying in period.

Cerebro-spinal fluid cytomorphology in tuberculous meningitis--a preliminary report.

The morphology of cells in centrifuged cerebrospinal fluid (C.S.F.

Studies on nonesterified fatty acids in rat intestinal cell membranes.

Lipid composition of total membrane fractions prepared from scraped rat intestinal mucosa and isolated epithelial cells were compared. Membranes prepared from mucosa had four times higher nonesterified fatty acids (NEFA) as compared to the epithelial cell membranes. Cholesterol and phospholipid contents were similar in both the membrane preparations but triglyceride content was high and di- and monoglyceride were low in epithelial cell membranes as compared to the mucosal membranes.

Comparison of cardiovascular risk factors in type II (non-insulin dependent) diabetics with and without coronary heart disease.

Cardiovascular risk factors in NIDDM were studied by comparing 175 subjects with coronary heart disease (CHD) to 173 subjects without CHD; both groups were matched with regard to male to female ratio, age at diagnosis of diabetes and body mass index. The risk factors included were hypertension, poor metabolic control, smoking and lipid abnormalities. Since the mean known duration of diabetes in subjects with CHD was longer compared to those without CHD (12.

Histopathological appraisal of carbon-dioxide laser dorsal root entry zone (DREZ) lesions in primates.

Dorsal Root Entry Zone (DREZ) thermocoagulation using radiofrequency has successfully been employed in the treatment of various deafferentation pain syndromes. The ability of surgical lasers to produce discrete lesions with precision has prompted their use in DREZ lesioning. The effects of carbon-dioxide laser induced DREZ lesions in the primate spinal cord were studied in the Bonnet monkey and the parameters necessary to produce a histologically ideal DREZ lesion were evaluated.
