RESUMEN

BACKGROUND: Women between 12 and 50 years are in the reproductive age. The likelihood of or actual presence of pregnancy should be ruled out before they are exposed to medical ionizing radiation. Fetal exposure to ionizing radiation can either induce malformation (teratogenic) or cancer. They should be exposed only when it is safe for the fetus or when the benefit far outweighs the risk in urgent medical conditions. The radiation dose in medical imaging is generally below the threshold to induce malformation (100 mGy) in the fetus, but there is indeed no safe level as the risk of cancer induction later in life can occur at any dose. The referring physician must obtain the last menstrual period (LMP) and sometimes carry out pregnancy test before sending their patients for examinations using ionizing radiation. However, there are circumstances in which these rules are waived. OBJECTIVE: The purpose of the study is to evaluate the role of the referring physician in the radiation protection of the fetus using the LMP. SUBJECTS AND METHODS: This is a prospective study over a 2-month period. All the request forms of menstruating women aged 12-50 years sent for conventional radiography are included in the study. RESULTS: One percent provided the LMP in the request forms. 0.6% (one) of our subjects was sure she is pregnant, but 13.7% (25) had an overdue menstruation. CONCLUSION: The level of compliance of the physicians with the referral guidelines for women of reproductive age is poor.

RESUMEN

AIMS AND OBJECTIVES: This study was designed to document the Transvaginal Scan (TVS) findings in women presenting with infertility and menstrual irregularities at the University of Calabar Teaching Hospital. MATERIALS AND METHODS: Subjects were women of reproductive age presenting at the University of Calabar Teaching Hospital with menstrual irregularities and infertility over a two year period, February 2011-January 2013. As part of their management, transvaginal scans were done and findings included a substantial number with polycystic ovarian cysts. Therefore the ovaries were further analysed with controls. RESULTS: Out of seventy-one women with age distribution of 22 to 46years, twenty- four(33.8%) presented with infertility, the rest presented with either menstrual irregularity alone or in combination with infertility. Polycystic ovaries (PCO), chronic pelvic inflammatory disease and fibroids were the main pathologies seen. PCO was by far the commonest. Ovarian volumes and follicular numbers were significantly higher in women with PCO than in controls, whereas their average follicular sizes were lower. CONCLUSION: PCO is the major finding in women with menstrual irregularity and infertility in the Calabar area. This hitherto poorly recorded pathology should be actively investigated in women representing with these symptoms by the use of TVS.

RESUMEN

BACKGROUND: Pyogenic osteomyelitis is still frequently seen in the developing world and the treatment of chronic osteomyelitis presents a considerable challenge despite advances in microbiological techniques, antibiotics and surgical techniques. Acute haematogenous osteomyelitis is commoner in children. RESULTS: In the pre-antibiotic era, mortality rate was high and progression to chronic osteomyelitis was common. A near similar scenario still exists in many developing countries due to the combination of inappropriate and/or inadequate antibiotic therapy, delayed presentation and unorthodox interventions by traditional healers. DISCUSSION: Chronic osteomyelitis may result from poorly treated or untreated acute osteomyelitis, open fractures, surgery for an array of orthopaedic conditions and from contiguous spread from infected soft tissue as may occur in diabetic foot infections. A large array of treatment techniques hinged on sequestrectomy/ debridement, management of dead space, improvement of oxygenation and perfusion to ischaemic tissue exist. Despite these, total eradication of disease is difficult. CONCLUSION: This article summarizes the pathology and methods of management available for pyogenic osteomyelitis. In its acute and chronic forms, the disease is likely to remain prevalent in the developing world until issues of ignorance, poverty and prompt access to appropriate and efficacious medical care are addressed.

RESUMEN

Diabetic foot ulceration and gangrene is a major cause of morbidity andmortality. This study has examined potential preventive footcare practices in a cohort of diabetic patients presenting with foot gangrene. One hundred and two (102) diabetic emergencies presented during the study period. Diabetic foot gangrene accounted for 27 (26%) of these cases. There were 18 males and 9 females (M:F = 2:1), with a mean age of 52+13 years. The mean duration of ulceration was 4±3 weeks and mean ulcer­gangrene interval was 1.2±0.5 weeks. Only 9 patients (33%) had been exposed to any form of footcare education, 15 patients (55%) treated their ulcers by unorthodox means, and 63% of the patients practiced no significant footcare. More widespread education and awareness is needed to prevent the continuing and serious problem of diabetic foot gangrene and consequent lower limb amputation
