Factors associated with stunting in infants aged 5-11 months in the Dodota-Sire District,rural Ethiopia

The contribution of various factors to malnutrition, particularly stunting, may differ among areas and communities. This cross-sectional study aimed to estimate the level of malnutrition and identify factors associated with the high level of stunting in breast-fed infants aged 5-11 mo living in Dodota-Sire District, Ethiopia. Infants (n = 305) and their mothers were examined physically, and anthropometric and demographic data were collected. The content of zinc, calcium and copper in breast milk was measured, and data collected on the type, frequency of consumption, and time of introduction of supplementary feeding. Overall, 36% were stunted, 41% underweight and 13% wasted. The highest prevalence of malnutrition was seen in infants aged 9-11 mo. Among mothers, 27% had chronic energy deficiency (body mass index, <18.5 kg/m(2)) and 20% were night blind, indicating that vitamin A deficiency was a serious problem. Infants fed >3 times/d, consuming >600 mL/d or consuming cow's milk in addition to cereals and/or legumes had markedly higher length-for-age Z-scores than their peers fed less frequently, consuming less food or not consuming cow's milk [differences: 0.39, 95% confidence interval (CI): 0.04-0.74; 0.17, 95% CI: 0.02-0.32; 0.40, 95% CI: 0.07-0.72, respectively). Infants of mothers with low concentrations of zinc in their breast milk were more stunted. In conclusion, the quality and quantity of foods consumed by infants is insufficient to prevent stunting. Thus it is necessary to increase the nutrient supply to infants by increasing intake and nutrient concentration of breast milk and of supplementary foods they consume, and by providing supplements to infants where appropriate.

Incidence and causes of cancellations of elective operation on the intended day of surgery at a tertiary referral academic medical center in Ethiopia

Background

Elective surgical case cancellation refers to any elective surgical case that is the list on the day prior to surgery but not operated upon as scheduled. Case cancellation has a major cause of psychological trauma to patients and their families. Despite little is known in Ethiopia. Therefore, this study aimed to assess incidence and reasons of cancellations of elective operation on the intended day of surgery at tertiary referral academic medical center in Ethiopia.

Methods

A prospective hospital-based cross-sectional study design was conducted in a tertiary referral academic medical center in Ethiopia among 146 participants. A self-administered questionnaire with an observatory checklist was used for collecting data from the anesthetist, nurse, and surgeons.

Result

In this study, 462 patients were scheduled for elective surgical operations. Among those, nearly almost one-third 146 (31.6%) of the operations were cancelled and 316 (68.4%) patients were operated on their planned date. The most common reason for cancellation were surgeon related (35.8%), patient related (28.7%), management related (21.2%) and anesthesia related factors (14. 4%). The cancellation was mainly due to improper scheduling (20.5%%), unavailability of surgeons (8.9%), unavailability of oxygen and blood (8%) and equipment (5.5%). Orthopedic (28.8%) and general surgery (17.1%) were the commonest cancelled cases.

Conclusion

The cancellation rate in our academic medical center remains high. Improper scheduling, unavailability of surgeons, medical illness, and unavailability of operating room equipment were the commonest reason for the cancellation of elective operation. Most cancellations were preventable. For this, proper preoperative assessment, proper scheduling, fulfilling necessary operating room equipment’s and cross-matched blood by the hospital and other stakeholders, early clear communication with operating room team like surgeons was recommended.

     

Evaluation of a new recombinant K39 rapid diagnostic test for Sudanese visceral leishmaniasis

A new rK39 rapid diagnostic dipstick test (DiaMed-IT-Leish) was compared with aspiration and a direct agglutination test (DAT) for diagnosis of visceral leishmaniasis (VL) in 201 parasitologically confirmed cases, 133 endemic controls, and in 356 clinical suspects in disease-endemic and -epidemic areas in Sudan. The sensitivity of the rK39 test in parasitologically confirmed VL cases was 90%, whereas the specificity in disease-endemic controls was 99%. The sensitivity of the DAT was 98%. In clinically suspected cases, the sensitivity of the rK39 test was 81% and the specificity was 97%. When compared with the diagnostic protocol based on the DAT and aspiration used by Médecins sans Frontières in epidemic situations, the positive predictive value was 98%, and the negative predictive value was 71%. This rK39 rapid diagnostic test is suitable for screening as well as diagnosis of VL. Further diagnostic work-up of dipstick-negative patients with clinically suspected VL is important. The ease and convenience of the dipstick test will allow decentralization and improved access to care in disease-endemic areas in Sudan.     

Guillain-Barré syndrome in Ethiopian patients

This is a ten years retrospective study conducted to assess the clinical profile and outcome of Guillain-Barré Syndrome (GBS) in Ethiopian patients. The medical records of all patients admitted with the diagnosis of GBS to the Department of Internal Medicine, Tikur Anbessa University Hospital, Addis Ababa, Ethiopia during the period September 1992 to September 2001 were reviewed. During the ten-year review period ninety-five patients were admitted with the diagnosis of GBS, of which eighty-one met the National Institute of Neurological and Communicative Disorders and Stroke diagnostic criteria. The mean age (SD) of patients was 34.4 +/- 14.4 years. The male to female ratio was 1.25:1. History of antecedent event such as upper respiratory tract infection, diarrhea and vaccination was obtained in 47/81 (58.1%) of patients. The majority of the patients 62 (78.5%), presented with an ascending areflexic quadriparesis while 10 (12.7%) presented with a descending type of arefilexic quadriparesis, but in 6 (7.4%) of the patients the weakness was confined to the lower extremities (i.e. Paraparetic variant). Signs of autonomic involvement were seen in 25/81 (30.9%). Cytoalbzuminological dissociation in the cerebrospinal fluid was demonstrated in 62.3%. EMG was done in 47 patients The commonest electrophysiologic abnormality encountered was demyelinating picture in 26 (55.3%) followed by mixed and axonal in 12 (25.5%) and 9 (19.1%) respectively). Nineteen (70.3% of 27 GBS patients for whom serology for HIV was done were seropositive. The clinical findings were similar in both groups, except for a higher frequency of CSF pleocytosis, need for ventilatory support and mortality among HIV-positive patients. The overall mortality was 25.9%. This study highlights the importance of GBS as a cause of peripheral nerve disease in our setup. The higher mortality rate observed in this study appeared to be related mainly to the lack of adequate intensive carefacility and highlights the need to improve these services. Further-more, the finding of high frequency of seropositivity among GBS patients in this study underlines the need for further prospective research on the association and clinical course of GBS and HIV, particularly in Africa where HIV/AIDS has become an important public health problem.     

Leprosy

Leprosy is a unique infectious disease with a prolonged incubation period and a predilection for skin and nerves. The involvement of nerves by the primary infection as well as the immunologically mediated reversal reactions result in impairment of nerve function and severe disabilities. The introduction of the World Health Organization Multi Drug Therapy over the last two decades has produced dramatic changes in the management and control programmes of leprosy. A recent important contribution to the understanding of leprosy pathogenesis has been the elucidation of the molecular basis for the entry of Mycobacterium leprae into the Schwann cell and the peripheral nerve. Leprosy still remains the commonest cause of peripheral neuropathy in developing countries.     

Sensorineural hearing loss in children with epidemic meningococcal meningitis at Tikur Anbessa Hospital

There are several reports on epidemic meningococcal meningitis in some areas of Ethiopia, which lie in the meningococcal meningitis belt of Africa. Very little is known about the neurological sequel of epidemic meningococcal meningitis, especially that of hearing loss. This hospital-based study was conducted prospectively at the Ear Nose Throat clinic of the Pediatric Outpatient Department of the Tikur Anbessa Hospital during the meningococcal meningitis epidemic from May to October 2000 in order to assess the hearing status of patients after completion of their course of treatment. Demographic, clinical, microbiologic, audiometric data were collected using a preformed questionnaire. One hundred forty one cases of pyogenic meningitis were examined at discharge and on subsequent visits. Most of the patients (73.5%) were between 5 and 12 years of age. The major bacteriological isolate from the cerebrospinal fluid in 48 cases (35.3%) of the specimens was meningococci. Hearing loss was the commonest neurological sequel at discharge constituting 25% of the cases. At least 12.5% of the patients had severe to profound sensorineural hearing loss. This level of hearing loss would affect communication abilities and impair studies in school if left without rehabilitative measures including hearing aids or other means. Large scale community based studies are required to determine the magnitude of hearing loss associated with epidemic meningococcal meningitis.     

Anti-malarial activity of withania somnifera L. Dunal extracts in mice

OBJECTIVE: This study aims at investigating the in vivo antiplasmodial activity of a traditionally used medicinal plant, Withania somnifera, L. Dunal, (Solanaceae). METHODS: Rodent malaria parasite, Plasmodium berghei, 0.2 ml of x l0(7) parasites, was inoculated into Swiss albino mice intraperitoneally. Extracts were administered by intra gastric tube daily for four days starting from the day of parasite inoculation. Negative controls received the same amount of solvent used to suspend the exracts and the positive controls were given chloroquine by the same route. Parasite suppressive effect and effects on body weight, packed cell volume (PCV) and body temperature were determined. RESULTS: Parasitemia percent inhibition of W. somnifera roots and root barks were 50.43% and 29.13% respectively, with 600 mg/kg dose. Inhibition was statistically significant at all dose levels, compared to the negative controls (p < 0.05), and maximum inhibition was seen at 600 mg/kg. CONCLUSION: Extracts of the leaves and root barks of W. somnifera showed parasite suppressive effect and a protective effect on PCV drop (at higher doses), both in dose-related fashions. However, the effects on body weight and body temperature falls are inconclusive.
