Mortality of patients following hip fractures in Barbados

A retrospective study of all patients admitted with hip fractures to the Queen Elizabeth Hospital in Barbados from January 1996 to December 1998 was conducted. There were 110 patients who had sustained either a femoral neck or peri-trochanteric fracture. The mean age was 80.7 years and 71.8 of the patients were women. Mortality at six months in 110 patients was 32.7 and 41.2 at 12 months in 102 patients. Forty-nine patients had open reduction and internal fixation of their fractures, forty-five patients were treated with Austin Moore prostheses and one patient had excisional arthroplasty. Patients with pre-operative cardiac abnormalities had a significantly higher mortality (60) at 12 months (p = 0.028). There was a linear correlation between age and mortality with mortality increasing with age. The length of time from admission to surgical procedure had no significant influence on mortality. Hip-fracture patients with cardiac abnormalities should be carefully evaluated and stabilized pre-operatively

A survey of cutlass ("Collins") injuries seen in the emergency department of the Queen Elizabeth Hospital in Barbados

For the period March to November 1998 inclusive, a prospective survey was conducted of all patients who sustained injuries with a cutlass or machete and were admitted to the Accident and Emergency Department of the Queen Elizabeth Hospital. Of the 77 patient admissions, 81 (62/77) were male. The average age was 28.8 years (range 8 to 73 years; standard deviation 13.1). Twenty-two per cent of the patients were less than 20 years old. The most common locations of the lacerations were upper extremity (59 lacerations) and scalp (16 lacerations). Thirty-four per cent of the patients (26/77) sustained lacerations to two or more anatomical locations. There were 23 fractures in 21 patients; skull fractures were the most common fractures (11). Of the 63 patients who responded to the question on whether they knew the identity of their assailants, 51 reported that they were attacked by someone known to them; eight were assaulted by a spouse or known family member. Eighty-six per cent of patients (66/77) were treated in the emergency room and discharged. Of the 11 patients admitted, eight required treatment in the operating theatre. The average length of stay was 3.6 days. There were no amputations or deaths. One patient sustained loss of vision in one eye. In Barbados, most victims of cutlass injuries are males who know their assailants and the morbidity is most often related to head injuries and to short-term physical disability due especially to lacerations of the hand and forearm.

An evaluation of medical school education in musculoskeletal medicine at the University of the West Indies, Barbados

At the University of the West Indies, Cave Hill campus, the Freedman and Bernstein musculoskeletal competency examination was administered to 22 medical students during the last month of their final year. Eighty-two per cent (82) of the students failed to score above the passing score of 73.1. Nineteen of the twenty-two students had taken an orthopaedic elective or rotation during their final two years. The questions were also categorized as Anatomy, Trauma and General Orthopaedics. All students failed to score above the passing score in Anatomy. Sixty-four per cent (64) failed in Trauma and 45 failed in General Orthopaedics. This study suggests that inadequacies in medical school preparation do exist at this campus of the University of the West Indies and the findings mirror those at medical schools in the United States of America.

Microspore culture in Corchorus olitorius: effect of growth regulators, temperature and sucrose on callus formation.

Culture of isolated microspores and of anthers on media containing IAA directed free microspore development to an embryogenic pathway in C. olitorius. The first division of microspores on transfer to culture media was symmetrical in contrast to the asymmetrical division seen in normal development in vivo. Initially, 10-30% microspores divided symmetrically, but only 0.2-1% of the dividing microspores continued dividing and produced multicellular microcalli. About 30% of these microcalli produced callus but only on medium with 2.0 mg/L zeatin and 0.1 mg/L IAA. Incubation in the dark at temperatures of 35 degrees C for 1 day and then 25 degrees C was found effective for induction of first embryonic division in Corchorus. The frequency of microspore callus formation was higher on medium containing either 3% or 5% sucrose. Addition of colchicine and addition of activated charcoal to the above medium did not enhance microspore division in Corchorus olitorius. On transfer to different media most calli produced roots but regeneration of shoots and embryos was not induced.
