Knowledge,attitude, and skills regarding sports medicine among football players and team doctors in the football super league in Malawi

A study was conducted among football players and team doctors in the football super league in Malawi to determine the level of knowledge, skills and attitude in sports medicine. One hundred football players and thirteen team doctors were involved in the study. Standardised questionnaires were used to collect data in an interview format. Among the players 37% had completed tertiary education and 60% had finished secondary school education. Most players had poor knowledge on prevention of injuries; had poor advice on diet; used illicit drugs or knew of fellow players using illicit drugs and believed in the role of magic in sports. All 13 team ‘doctors’ worked full-time in paramedical fields: 3 were orthopaedic clinical officers, 2 were physiotherapists and the rest were in various fields, such as dental technician, pharmacy assistant, medical assistant and dermatology technician, where trauma is not part of their basic training. Most team “doctors” were aware of the impact of HIV/AIDS on sports but few had good knowledge of the role of nutrition in sports and the effect of performance enhancing drugs in sports. Most believed in the role of magic in sports. Recommendations are made on the basis of these findings.     

Autologous bone marrow transplantation using marrow incubated with Asta Z 7557 in adult acute leukemia

The sensitivity of human myeloblastic leukemic (CFU-L) and normal hemopoietic stem cells (CFU-GM and BFU-e) to Asta Z 7557 (INN Mafosfamide) was studied with regard to autologous bone marrow transplantation (ABMT) with cleansed marrow for consolidation therapy in adult patients with acute leukemia (AL) in remission. Establishment of the dose-response curves for CFU-GM (n = 37), BFUe (n = 11), and myeloblastic CFU-L (n = 9) demonstrated a wide range of sensitivity from patient to patient for all three progenitors. Whereas CFU-L, CFU- GM, and BFU-e grown in semisolid cultures disclosed similar sensitivities to Asta Z 7557, long-term culture (LTC) studies (n = 41) indicated a higher resistance of early progenitors. In an effort to achieve a maximum tumor cell kill and yet spare a sufficient amount of normal stem cells to ensure consistent engraftment, we defined the optimal dose for marrow cleansing as the dose sparing 5% CFU-GM (LD95). This dose was established from a preincubation test (PIT) realized on a 10-mL marrow aspirate taken 15 days before marrow collection in each individual patient. Twenty-four adult patients while in remission of AL (20 in complete remission, four in partial remission) were consolidated by cyclophosphamide 60 mg/kg X 2 and total body irradiation at 10 Gy followed by ABMT with marrow cleansed by Asta Z 7557 according to the specification described above. Patients were divided in two groups: group 1, unfavorable prognosis (11 patients); group 2, standard prognosis [13 patients in first complete remission (CR)]. All patients engrafted on leukocytes (median day for recovery to 10(9)/L: day 30), patients with ALL recovered faster than patients with ANL (median day 19 v 34). Similarly, recovery of platelets to 50.10(9)/L occurred sooner in patients with ALL (median day 67, range day 23 through 90) whereas three patients with acute nonlymphoblastic leukemia (ANLL) in group 2 had to be supported with platelet transfusions for more than one year. In group 1, six patients had recurrent tumor within six months; three patients died from toxicity with no evidence of tumor. Two patients are still disease-free with a short follow-up (nine and ten months). In group 2, two patients died from toxicity with no evidence of leukemia three and 16 months post-ABMT. One patient with a M5 ANLL and one patient with ALL relapsed at six and 15 months, respectively. Nine patients have remained in CR or are disease-free with a median follow-up of 22 months.(ABSTRACT TRUNCATED AT 400 WORDS)     

The changing role of the primary school teacher in Swaziland in the context of HIV/AIDS: teacher as caretaker and economic provider

Swaziland has the world''s highest HIV prevalence with 26% of adults aged 15–49 years living with HIV. There are approximately 17,000 Swazi children aged 0 to 14 years living with HIV. This qualitative study explored the experiences of Swazi teachers supporting learners living with or affected by HIV/AIDS, with a specific focus on the extent to which teachers are aware of the “Rights of the Child” in their teaching and approaches. Important themes emerged from thematic analysis including the following: teachers provided more than education to learners living with and affected by HIV, including material goods and additional time, in some cases at the expense of other learners. In the era of HIV/AIDS, the teacher has become the emotional caretaker and economic provider in addition to the predictable role of educator in Swaziland. Education curricula in HIV-burdened countries need to modify training programmes and support services available to teachers to accommodate the complex role that teachers play in caring for learners living with and affected by HIV.     

Marrow purging in autologous bone marrow transplantation for T-lineage acute lymphoblastic leukemia: efficacy of ex vivo treatment with immunotoxins and 4-hydroperoxycyclophosphamide against fresh leukemic marrow progenitor cells

A lymphoblast progenitor cell assay was used to evaluate the antileukemic efficacy of marrow-purging protocols that employed intact ricin immunotoxins (IT) and 4-hydroperoxycyclophosphamide (4-HC) against clonogenic primary T-lineage marrow blasts freshly obtained from 12 T-lineage acute lymphoblastic leukemia (ALL) patients. Residual T-lineage blast colonies were observed after treatment with 1 micrograms/mL T101 (anti-CD5)-Ricin (R) + G3.7 (anti-CD7)-R in eight of 12 cases and after 100 micrograms/mL 4-HC in six of nine cases. By comparison, a combination of IT and 4-HC proved very effective against T-lineage leukemic progenitor cells, and no residual blast colonies were observed in any of the eight cases studied. We conclude that future trials should consider combined treatment protocols such as IT + 4-HC for more effective purging of autologous marrow grafts.     

IS CARDIOVASCULAR DISEASE A RISK FACTOR IN THE DEVELOPMENT OF AXONAL POLYNEUROPATHY?

Objectives: To determine if cardiovascular disease may be a risk factor in the development of chronic idiopathic axonal polyneuropathy (CIAP). Methods: In this incidence case-control study, the prevalence of cardiovascular disease and risk factors in 97 patients with CIAP (mean age 67.5 (SD 7.9) years) and the prevalence of neuropathic features in 97 patients with peripheral arterial disease (PAD) (mean age 67.1 (SD 7.3) years) were investigated. The results were compared with those for 96 age and sex matched controls without diagnosed PAD or polyneuropathy (mean age 67.5 (SD 9.1) years). In a randomly chosen subgroup of 23. patients with CIAP, 42 patients with PAD, and 48 controls, an electrodiagnostic investigation was performed. Results: Patients with CIAP more often had manifest cardiovascular disease and cardiovascular risk factors than controls (stroke 18% v 6% of patients, odds ratio (OR) 3.2 (95% confidence interval (0) 1.8 to 5.9); heart disease 29% v 15%, OR 2.4 (95% Cl 1.2 to 4.9); family history of cardiovascular disease 42% v 21%, OR 2.8 (95% Cl (1.5 to 5.2); hypertension 56% v 39%, OR 2.0 (95% Cl 1.1 to I I 3.6); hypercholesterolaemia 46% v 21%, OR 3.3 (95% Cl 1.5 to 7.3); current smoking 38% v 23%, OR 2.1 (95% Cl I. I to 3.9)). The prevalence of cardiovascular disease and cardiovascular risk factors was lower than in patients with PAD. Patients with PAD more often had polyneuropathy than controls (15% v 5%, OR 3.3 (95% Cl 1.1 to 10.0)). There was a trend towards lower nerve conduction velocities and lower amplitudes on electrodiagnostic investigation compared with controls. Conclusion: This study shows that cardiovascular disease and CIAP often coexist, and therefore cardiovascular disease may be a cofactor in the development of CIAP.     

ARTHROSCOPIC EVALUATION AND MANAGEMENT OF MENISCAL INJURIES OF THE KNEE

50 cases of isolated meniscal injuries of the knee were evaluated and managed arthroscopically. 56% of the cases were in 25–35 year age group. In 80% of the cases military training and contact sports was the mode of injury. Maximum (42%) patients reported late (> 2 years) after the injury. On presentation, they had an average Lysholm knee score of 53.76. Medial meniscal lesion was seen in 74%. Commonest pattern of tear encountered was a longitudinal tear (40%). Depending on pattern and extent of lesion, partial meniscectomy (60%), subtotal meniscectomy (14%) and total meniscectomy (26%) were performed. Patients were followed up at six months and one year. The average Lysholm score at 6 months was 83.3 and at one year 79.5. At one year, the patient satisfaction level was 82% and patients who underwent partial meniscectomy had the best results.KEY WORDS: Arthroscopy, Meniscal tear     

Frequency of peripheral arterial disease and venous insufficiency in toenail onychomycosis

Onychomycosis in toenails is a common fungal infection and vascular abnormalities of lower extremities have been thought as one of the predisposing conditions. The aim of this study was to evaluate predisposition effect of venous insufficiency and peripheral arterial disease on toenail onychomycosis. Thirty‐three patients with bilateral onychomycosis in toenails and 37 control subjects, who had healthy nails, were enrolled in the study. Veins and arteries of lower extremities were examined with Doppler ultrasound in terms of venous insufficiency or peripheral arterial disease. Patients with onychomycosis presented more frequent venous insufficiency than the control group (42.4% and 10.8%, respectively; P = 0.003). Although all patients had bilateral onychomycosis, reflux was bilateral in six out of 14 patients with onychomycosis (42.8%). No significant difference in frequency of peripheral arterial disease was found in patients, compared to healthy controls. Our study demonstrated a significant relationship between onychomycosis and venous insufficiency, but not with peripheral arterial disease. Also, we point out discordance with bilateral onychomycosis and unilateral venous insufficiency.
