Otitis media with effusion (OME) is a constant finding in children with mucopolysaccharidoses (MPS). Affected children may also present the anaesthetist with a difficult airway. A 7-year retrospective review of the management of OME in individuals with MPS was carried out.

Cardiac arrhythmias are noted in a significant proportion of chronic renal failure (CRF) patients on hemodialysis (HD), and may contribute to cardiovascular mortality. A number of factors have been implicated in the genesis of these arrhythmias. The role of silent myocardial ischemia (SMI), however, has not been evaluated systematically.

Protein kinase inhibitor (PKI) is a potent endogenous inhibitor of the cyclic AMP (cAMP)-dependent protein kinase (PKA). It functions by binding the free catalytic (C) subunit with a high affinity and is also known to export nuclear C subunit to the cytoplasm. The significance of these actions with respect to PKI's physiological role is not well understood.

This report describes the use of gastric tonometry to measure gastric mucosal ischemia/intestinal mucosa pH (pHi) in a patient treated for celiac artery compression syndrome. Significant gastric mucosal ischemia was demonstrated prior to celiac artery decompression as indicated by a pHi of 7.29.

NF-kappa B plays a critical role in the transcriptional regulation of proinflammatory gene expression in various cells. Cytokine-mediated activation of NF-kappa B requires activation of various kinases, which ultimately leads to the phosphorylation and degradation of I kappa B, the NF-kappa B cytoplasmic inhibitor. The food derivative curcumin has been shown to inhibit NF-kappa B activity in some cell types.

A total of 86 renal transplant patients who were transplanted with live related donor (LRD) and live unrelated donor (LURD) kidneys were studied for opportunistic infections. Immune diagnosis of Toxoplasma, Cytomegalovirus (CMV), Herpes-simplex virus type II (HSV-2), Aspergillosis and Tuberculosis was carried out in these patients along with sputum examination, CSF studies and biopsy of lymphnode and other tissues in few cases. A high degree of Toxoplasma, CMV & HSV-2 positivity was seen in transplanted patients.

Nine cholesteatomas, seven middle ear granulations and five deep meatal skin specimens were analysed for gelatinase activity at molecular weights corresponding to those of matrix metalloproteinase-1 (MMP-1) using SDS PAGE zymography. Gelatinase activity at 41-43 kDa and 45-47 kDa was investigated. Western blotting was employed using a primary monoclonal antibody to MMP-1 to provide a qualitative assessment of MMP-1.

A qualitative and quantitative study of the presence of Matrix metalloproteinase-2 (MMP-2) and Matrix metalloproteinase-9 (MMP-9) in cholesteatoma was performed. Ten cholesteatoma and four deep meatal skin specimens were analysed for gelatinase activity at molecular weights corresponding to MMP-2 and MMP-9 using Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis (SDS PAGE) Zymography. Gelatinase activity at 72 kDa and 92 kDa was investigated.

A "branchial cyst" in a patient above 40 years old may turn out to be a malignant cystic nodal metastasis from a primary tumour in the tonsil. We present a case of a 45-year-old woman in whom an initial mistaken diagnosis of branchial cyst was made. The neck mass was discovered to be malignant and the left tonsil was subsequently implicated as the primary source.

Twenty five hyperthyroid patients and 25 healthy volunteers were evaluated for carbohydrate metabolic disturbance with an oral glucose tolerance test and glycosylated haemoglobin percentage. Insulin secretory response was studied in 17 hyperthyroids and 10 controls. A varying degree of abnormality was noted in hyperthyroids.

The morphology and number of cells in the trophectoderm (TE) and inner cell mass (ICM) of buffalo blastocysts derived from in vitro fertilization and cultured in the presence or absence of insulin-like growth factor-I (IGF-I) were analyzed by differential fluorochrome staining technique. The total cell number (TCN), TE number, and ICM cell number were significantly higher in blastocysts developed in vitro in the presence of IGF-I as compared to blastocysts developed without IGF-I (P < 0.01).

The aetiology of chronic rhinitis and nasal obstruction is often elusive and obscure. Many different causes have been documented including allergens, cigarette smoke, cold dry air, viruses, sulphur dioxide and industrial pollutants. This is the first case we have been able to identify of rhinitis associated with exposure to high levels of lead through indoor pistol shooting.

Thirty eight patients underwent Holter ECG monitoring for a 48 hour period covering dialysis and intermediate period to detect incidence of myocardial ischemia manifesting as ST segment changes. Seventeen patients (44.7%) had 165 episodes of dynamic ST segment changes lasting from 1 to 177 minutes, with maximum ST depression of 4 mm.

To monitor the activity of the humoral component in graft dysfunction following renal transplantation using live related donors, flowcytometric cross-match procedure was adopted. Antidonor antibodies were detected in the sera of both pre- and post-transplant patients using conventional serological cytotoxicity cross-match and flowcytometric cross-match assays. In the 52 pretransplant samples no significant differences were observed in flowcytometric and cytotoxicity tests except in 2 secondary transplant cases which were negative by cytotoxicity test.

Sensitization state of 119 patients of end-stage renal disease registered for live related donor transplant was assessed by determining the panel reactive antibody (PRA) status and the donor-specific crossmatch positivity. Eighty one patients (69.1%) showed no PRA, whereas 27 (22.

Adenoidectomy in this country is typically performed as an in-patient procedure requiring an overnight stay in hospital but experience from other countries shows that adenoidectomy can be safely performed as a day case procedure. In Leicester, a prospective study of day case adenoidectomy was initiated in 1991 under carefully monitored conditions. We report on 721 patients entered in the first 3 years.
