Long-term results of ossiculoplasty: reasons for surgical failure.

Objectives: To present the value of a dedicated ear audit clinic, the overall long-term results of ossiculoplasty, and the reasons for surgical failure.

Study Design: Retrospective analysis was performed on ossiculoplasty cases in a county hospital. The information was extracted from a computer database.

An unusual case of hyponatraemia in diabetic ketoacidosis.

This report outlines a case of diabetic ketoacidosis associated hyponatraemia in an 18 year old woman with type 1 diabetes who presented to the accident and emergency department and was quickly admitted to the intensive treatment unit. Causes of hyponatraemia include sodium depletion, pseudohyponatraemia, and extracellular hypertonicity. Hypertonicity secondary to hyperglycaemia is thought to be the major cause of hyponatraemia in diabetic ketoacidosis.

An international otology database.

There are many reports in the literature on the outcome of ear surgery. However, it is difficult to make comparisons from these reports because of a lack of uniformity in the way in which outcomes are reported. At the same time, the general public expects doctors to provide them with information regarding the benefits and risks of surgery.

Sustained silver-releasing dressing in the treatment of diabetic foot ulcers.

This study investigated the clinical performance and safety of a sustained silver-releasing foam dressing, Contreet Foam, in the treatment of diabetic foot ulcers. Twenty-seven patients with diabetic foot ulcers of grade I or II (Wagner's classification) were followed for six weeks: one week run-in using Biatain dressings, four weeks' treatment with Contreet dressings. Four ulcers healed during the four-week treatment with Contreet 56% in average.

Assessing computer skills in Tanzanian medical students: an elective experience.

Background: One estimate suggests that by 2010 more than 30% of a physician's time will be spent using information technology tools. The aim of this study is to assess the information and communication technologies (ICT) skills of medical students in Tanzania. We also report a pilot intervention of peer mentoring training in ICT by medical students from the UK tutoring students in Tanzania.

Plasma glucose measurement with the Yellow Springs Glucose 2300 STAT and the Olympus AU640.

Background: Diabetes mellitus is an important diagnosis. New criteria have been defined for impaired glucose metabolism and, accordingly, there is a need for precise and accurate glucose analysis for the correct classification of patients. However, neither the World Health Organisation nor the National Service Framework for Diabetes in England and Wales deal with the associated analytical issues for plasma glucose.

Concomitant nasal procedures in endoscopic dacryocystorhinostomy.

Dacryocystorhinostomy (DCR) is the preferred treatment for lacrimal duct blockage. Endoscopic DCR has been practised increasingly in recent years as it avoids a facial scar and can be performed as a day procedure. Recent improvements in endonasal surgical technique led to success rates of up to 90 per cent.

Methods: In a double-blind study, one drop of 0.

Practical experience with intensity-modulated radiotherapy.

At the Ipswich Hospital implementation of intensity-modulated radiotherapy (IMRT) commenced in February 2001 based on an established 3D conformal radiotherapy (3D CRT) service. This paper describes our experiences as we commissioned a fully-integrated IMRT planning and delivery system, and established IMRT within the department. Commissioning measurements incorporated a series of tests to ensure the integrity of the system and form the basis of routine quality assurance (QA) procedures.

High levels of 150-kDa insulin-like growth factor binding protein three ternary complex in patients with acromegaly and the effect of pegvisomant-induced serum IGF-I normalization.

Objective: To assess the effect of pegvisomant-induced serum insulin-like growth factor 1 (IGF-1) normalization on IGF binding proteins 1, 2, 3 (IGFBP-1, IGFBP-2 and IGFBP-3), total, non-bound (45 kDa) and 150-kDa ternary complex-associated IGFBP-3, and in vivo IGFBP-3 proteolysis in patients with active acromegaly.

Design: The above parameters were measured in 16 patients (median age 57 (range 27-78)) with active acromegaly (serum IGF-I at least 30% above the upper limit of an age-related reference range after washout) in a paired manner on samples obtained after washout and the first occurrence of serum IGF-I normalization during pegvisomant therapy (median dose 15 mg/day (10-40 mg)).

Results: Total IGFBP-3 and 150-kDa ternary complex-associated IGFBP-3 were significantly elevated in patients at baseline compared to controls ((mean+/-SEM) 4345+/-194 vs.

Imaging of pancreatic adenocarcinoma with emphasis on multidetector CT.

Pancreatic adenocarcinoma is the fourth most frequent cause of cancer-related death. The incidence is increasing and the overall survival has altered little in recent years. Moreover, patients usually present late with inoperable disease and curative resection by standard pancreatico-duodenectomy (Whipple's procedure) is associated with significant morbidity.

Pegvisomant-induced serum insulin-like growth factor-I normalization in patients with acromegaly returns elevated markers of bone turnover to normal.

Active acromegaly is associated with increased biochemical markers of bone turnover. Pegvisomant is a GH receptor antagonist that normalizes serum IGF-I in 97% of patients with active acromegaly. We evaluated the effects of pegvisomant-induced serum IGF-I normalization on biochemical markers of bone and soft tissue turnover, as well as levels of PTH and vitamin D metabolites, in 16 patients (nine males; median age, 52 yr; range, 28-78 yr) with active acromegaly (serum IGF-I at least 30% above upper limit of an age-related reference range).

The effect of pegvisomant-induced serum IGF-I normalization on serum leptin levels in patients with acromegaly.

Background: In humans, serum leptin correlates positively with fat mass. GH is lipolytic and patients with active acromegaly have lowered serum leptin compared to age, sex and body mass index (BMI)-matched controls, but a direct influence of GH on serum leptin remains unclear. In patients with acromegaly, total leptin increases following successful pituitary surgery and during somatostatin (SMS) analogue therapy (despite no change in BMI) but whether this represents changes in soluble leptin receptor, bound or free leptin is unclear.

Documentation in orthopaedic surgery - do integrated care pathways work?

Integrated care pathways (ICPs) are being widely adopted in orthopaedic surgery. This study compares the quality of medical notation in an ICP with traditional record keeping. During a 3-month period, 53 total hip replacements (ICP notation) and 30 total knee replacements (traditional notation) were performed.

A prospective study of genito-urinary dysfunction after surgery for colorectal cancer.

Objective: To establish the incidence of impotence and urinary dysfunction after different forms of pelvic and colorectal surgery.

Patients And Methods: Over a period of one year, 78 consecutive patients, mean age 66.8 years (range 43-91 years), underwent surgery for colorectal cancer.

Successful treatment of chronic anal fissure with diltiazem gel.

OBJECTIVE: Diltiazem is a calcium channel blocker that has shown potential to heal chronic anal fissures. We have prospectively evaluated the treatment of patients with anal fissure with diltiazem gel (SLA Pharma, UK). PATIENTS AND METHODS: All patients with chronic anal fissure from September 1999 to May 2000 were treated topically with 8 mg 2% diltiazem hydrochloride gel (equivalent to 2 cm of gel supplied by SLA Pharma) three times daily.

The anaesthetic management of a patient with a reninoma.

We report on the anaesthetic management of a 28-year-old woman presenting for excision of a reninoma. This is a very rare tumour of the juxtaglomerular cells of the kidney, which can be cured immediately by surgery. Previous reports have failed to record the presence or absence of peri-operative cardiovascular lability.

Ipswich lacrimal tube: pedicle nasal septal tube for the reconstruction of lacrimal drainage passage.

Canalicular blockage of the lacrimal system still remains a major challenge for oculoplastic surgeons. The conventional treatment of conjunctival dacryocystorhinostomy using the Lester Jones bypass tube is often associated with tube migration and foreign body reaction. The authors report a new technique to reconstruct the lacrimal passage on a single patient with severe canalicular obstruction following repeated failures from previous Lester Jones tube operations.

Orthopaedic Specialist Registrar training and attitudes to spine surgery in the United Kingdom: reasons for poor recruitment and suggestions for improvement.

In order to improve the provision of spinal surgery in the United Kingdom, the number of Specialist Spinal Surgeons and Surgeons with an Interest in Spinal Surgery needs to increase by 25% from the existing 175 surgeons. A survey of Specialist Orthopaedic Registrars was performed, which quantifies the predicted shortfall in the number intending to practise spinal surgery. The attitudes towards and perceptions of this field were obtained to identify factors that could be discouraging an interest in spine surgery.
