Early palliative care in newly diagnosed cancer in Ethiopia: feasibility randomised controlled trial and cost analysis

OBJECTIVES

Globally, cancer deaths are rising. In low-and-middle-income countries, there is a gap in access to palliative care (PC). We designed a feasibility trial to study the initiation of early PC in patients with cancer in Addis Ababa, Ethiopia.

METHODS

A randomised controlled trial (RCT) of standard cancer care versus standard cancer care plus in-home PC was conducted. Follow-up was at 8 and 12 weeks. Primary outcomes were: (1) feasibility, (2) patient-reported PC outcomes (African Palliative Care Association Palliative Outcome Scale (APCA POS)), and (3) costs.

RESULTS

Of 95 adults randomised (mean age 49.5 years; 66% female), 27 completed 3 study visits. Of these, 89% had stage III or IV disease. Recruitment was feasible, but attrition was high. APCA POS use was feasible, with significant within-arm improvements: 24% versus 18% reduction (p<0.0002, p<0.0025) in PC versus standard care, respectively. Standard care subjects reported higher out-of-pocket payments (5810 Ethiopian birr) (ETB) and lost wages of informal caregivers (74 900 ETB), multiple times an average Ethiopian salary (3696 ETB).

CONCLUSION

It is feasible to conduct an RCT of early PC for patients with cancer in Ethiopia. Retention was the biggest challenge. This study revealed opportunities to improve care, and important feasibility results to inform future, larger scale PC research in Ethiopia and beyond.

Rationale and study design: A randomized controlled trial of early palliative care in newly diagnosed cancer patients in Addis Ababa, Ethiopia

Patient-reported outcomes and economic aspects of Palliative Care (PC) provision in low-income countries (LIC) are under-studied. Demonstrating the economic value of PC is key to sustainability and guiding health care policy. Our preliminary data in Ethiopia demonstrated a widespread need for PC, poor access to it, and high out of pocket payments (OOP). We suspect that in this and other LIC, PC may function not only to reduce suffering but also as a poverty reduction strategy.We are conducting a randomized controlled trial of standard Oncology care versus standard Oncology care plus PC in newly diagnosed cancer patients in Addis Ababa. Ninety-seven adults presenting to Oncology Clinic will be randomized in a 1:1 ratio. Subjects receiving PC will meet with a PC provider at time of enrollment and at follow up visits in their homes. All subjects will be assessed via questionnaire at enrollment and follow-up Oncology visits at 8 ± 4 and 12 ± 4 weeks. A cost-consequence analysis will be performed, to include: patient-reported OOP and healthcare utilization, the latter to be assessed through chart adjudication. Outcomes will include change in African Palliative Care Association Palliative Outcome Score, changes in OOP and healthcare utilization.We hypothesize that the cost of home-based PC will be offset by improvements in patient-reported outcomes, decreased OOP and healthcare utilization, rendering PC cost-effective in this LIC. These findings may lead to widespread dissemination of an effective, sustainable and cost-saving public PC delivery strategy that would improve the quality of life and death for millions of people.

Non-communicable disease clinics in rural Ethiopia: why patients are lost to follow-up

Background

Providing medical care for non-communicable diseases (NCDs) in rural sub-Saharan Africa has proved to be difficult because of poor treatment adherence and frequent loss to follow-up (LTFU). The reasons for this are poorly understood.

Objective

To investigate LTFU among patients with two different but common NCDs who attended rural Ethiopian health centres.

Method

The study was based in five health centres in southern Ethiopia with established NCD clinics run by nurses and health officers. Patients with epilepsy or hypertension who were lost to follow-up and non-LTFU comparison patients were identified and traced; a questionnaire was administered enquiring about the reasons for LTFU.

Results

Of the 147 LTFU patients successfully located, 62 had died, moved away or were attending other medical facilities. The remaining 85 patients were compared with 211 non-LFTU patients. The major factors associated with LTFU were distance from the clinic, associated costs and a preference for traditional treatments, together with a misunderstanding of the nature of NCD management.

Conclusions

The delivery of affordable care closer to the patients' homes has the greatest potential to address the problem of LTFU. Also needed are increased levels of patient education and interaction with traditional healers to explain the nature of NCDs and the need for life-long management.

Using a mentorship model to localise the Practical Approach to Care Kit (PACK): from South Africa to Ethiopia

The Federal Ministry of Health, Ethiopia, recognised the potential of the Practical Approach to Care Kit (PACK) programme to promote integrated, comprehensive and evidence-informed primary care as a means to achieving universal health coverage. Localisation of the PACK guide to become the 'Ethiopian Primary Health Care Clinical Guidelines' (PHCG) was spearheaded by a core team of Ethiopian policy and technical experts, mentored by the Knowledge Translation Unit, University of Cape Town. A research collaboration, ASSET (heAlth Systems StrEngThening in sub-Saharan Africa), has brought together policy-makers from the Ministry of Health and health systems researchers from Ethiopia (Addis Ababa University) and overseas partners for the PACK localisation process, and will develop, implement and evaluate health systems strengthening interventions needed for a successful scale-up of the Ethiopian PHCG. Localisation of PACK for Ethiopia included expanding the guide to include a wider range of infectious diseases and an expanded age range (from 5 to 15 years). Early feedback from front-line primary healthcare (PHC) workers is positive: the guide gives them greater confidence and is easy to understand and use. A training cascade has been initiated, with a view to implementing in 400 PHC facilities in phase 1, followed by scale-up to all 3724 health centres in Ethiopia during 2019. Monitoring and evaluation of the Ministry of Health implementation at scale will be complemented by indepth evaluation by ASSET in demonstration districts. Anticipated challenges include availability of essential medications and laboratory investigations and the need for additional training and supervisory support to deliver care for non-communicable diseases and mental health. The strong leadership from the Ministry of Health of Ethiopia combined with a productive collaboration with health systems research partners can help to ensure that Ethiopian PHCG achieves standardisation of clinical practice at the primary care level and quality healthcare for all.

Effect of interscalene anaesthesia on cerebral oxygen saturation

Interscalene blockade (ISB) is commonly associated with Horner's syndrome, indicating spread of injectate to the cervical sympathetic chain. Cervical sympathetic nerve activity (SNA) is believed to influence cerebral autoregulation, and a decrease in sympathetic tone may alter cerebral blood flow (CBF). This study investigated whether ISB influenced CBF in patients undergoing shoulder surgery. Patients (n=30) scheduled for elective shoulder arthroscopy were recruited. Cerebral oxygen saturation (ScO(2)) of the left and right frontal cortices was continuously measured during ISB administration, sedation and anaesthetic induction. Baseline ScO(2) was similar in blocked and unblocked sides (74 ± 5% and 73 ± 5% respectively, P=0.70). ScO(2) decreased with sedation (-3 ± 3% and -4 ± 3%, P=0.93), and increased with pre-oxygenation and general anaesthesia (P <0.01). Following ISB there was no change in ScO(2) between blocked and unblocked sides (P=0.18), or any difference between right- or left-sided ISB. ISB is not associated with an increase in CBF as indicated by ScO(2), despite the presence of Horner's syndrome.

Seven key actions to eradicate rheumatic heart disease in Africa: the Addis Ababa communiqué

Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) remain major causes of heart failure, stroke and death among African women and children, despite being preventable and imminently treatable. From 21 to 22 February 2015, the Social Cluster of the Africa Union Commission (AUC) hosted a consultation with RHD experts convened by the Pan-African Society of Cardiology (PASCAR) in Addis Ababa, Ethiopia, to develop a ‘roadmap’ of key actions that need to be taken by governments to eliminate ARF and eradicate RHD in Africa.

Seven priority areas for action were adopted: (1) create prospective disease registers at sentinel sites in affected countries to measure disease burden and track progress towards the reduction of mortality by 25% by the year 2025, (2) ensure an adequate supply of high-quality benzathine penicillin for the primary and secondary prevention of ARF/RHD, (3) improve access to reproductive health services for women with RHD and other non-communicable diseases (NCD), (4) decentralise technical expertise and technology for diagnosing and managing ARF and RHD (including ultrasound of the heart), (5) establish national and regional centres of excellence for essential cardiac surgery for the treatment of affected patients and training of cardiovascular practitioners of the future, (6) initiate national multi-sectoral RHD programmes within NCD control programmes of affected countries, and (7) foster international partnerships with multinational organsations for resource mobilisation, monitoring and evaluation of the programme to end RHD in Africa.

This Addis Ababa communiqué has since been endorsed by African Union heads of state, and plans are underway to implement the roadmap in order to end ARF and RHD in Africa in our lifetime.

Hematoimmunological profile at gilgel gibe field research center, southwest ethiopia

BACKGROUND

Health and disease can only be distinguished by accurate and reliable reference values of a particular laboratory test. In interpreting laboratory test results, usually the reported values are compared with established reference values from developed countries. Now it is a fact that there is considerable variation in hematology reference intervals by several variables. However, such data at a population level are scanty in the Ethiopian situation. Therefore, this study was conducted to determine the hematological and immunological values in a community setting.

METHODS

A population-based cross-sectional study was conducted in Gilgel Gibe Field Research Center (GGFRC) from late September 2008 to end of January 2009. A tsample of 1,965 individuals was included in the study. Blood sample was collected by vacutainer tube and transported to Jimma University Specialized Hospital laboratory. Data were entered in to EpiData and analyzed using SPSS for Windows version 16.0 and STATA 11.

RESULTS

A total of 1965 (955 men and 1010 women) individuals were studied. The mean red blood cell count for men and women was 4.55 × 10(12)/L and 4.34 × 10(12)/L (95 percentile range between 2.9 and 5.7 × 10(12)/L) and 4.34 ×10(12)/L (95 percentile range between 2.8 and 5.2 × 10(12)/L), respectively. On the other hand, the red blood cell count of 95% of the men and women lied between 2.9-5.7 × 10(12) cells/L and 2.8-5.2 × 10(12) cells /L, respectively. The mean hemoglobin value for men was 13.6 gm/dl and for women 12.7 gm/dl. The mean corpuscular volume for men and women was 90.2 fl and 90.8 fl, respectively. The mean platelet value for men was 229.1 ×10(9) cells/L and for women 241.3 ×10(9) cells/L. The mean white blood cells count for men and women was 6.08 ×10(9) cells/L and 6.12 ×10(9) cells/L, respectively. The mean CD4 value was 809 cell/µl for men and 868 cell /µl for women. Forty two percent of the study participants had O blood group.

CONCLUSION

The hematologic and immunologic profile of the studied population in Southwest Ethiopia is different from the reports from other countries and the standards described in western literature. We recommend conducting similar nationwide study to determine the immunological and hematological reference values of the Ethiopian population as a whole.

Biochemical profile at gilgel gibe field research center, southwest ethiopia

BACKGROUND

The biochemical reference ranges currently used in developing countries are derived from data collected from populations living in developed countries. However, it is a fact that there is considerable variation in biochemical reference intervals by several variables. Moreover, reference ranges provided by different laboratory manuals and books do not also solve this problem. Biochemical profile at population level is scanty in the Ethiopian situation. Therefore, this study was conducted to determine the biochemical profiles for general population in community settings.

METHODS

A population-based cross-sectional study was conducted in Gilgel Gibe Field Research Center (GGFRC) from late September 2008 to end of January 2009. The study setting included both rural (majority) and urban dwellers. A total of 1,965 (955 men and 1010 women) individuals aged 15-64 years were included. Fasting blood glucose was determined immediately at field. Blood sample was collected by vacutainer tube without anticoagulant and transported to Jimma University Specialized Hospital laboratory for determination of total cholesterol, triglycerides, total serum protein, blood urea nitrogen, creatnine, uric acid, alanine aminotransferase and aspartate aminotransferase. Data were entered into EpiData and analyzed using SPSS for Windows version 16.0 and STATA 11.

RESULTS

The mean total cholesterol value for both sexes was 141.0 mg/dl with higher values for women at different age strata. The mean FBS level of the study population was 96 mg/dl. The mean values for blood urea nitrogen, creatinine and uric acid were 14.1 mg/dl, 0.86 mg/dl and 4.4 mg/dl. The mean level of alanine aminotransferase and aspartate aminotransferase of the study population were 27.2 U/L and 31.2 U/L, respectively.

CONCLUSION

All biochemical values in this study except for blood urea nitrogen were not different from values in other reports. Even though our finding showed similar ranges with reported values, there might be a variation in values across the country. Therefore, we recommend conducting similar nationally representative study to validate the current finding.

Physical measurement profile at gilgel gibe field research center, southwest ethiopia

BACKGROUND

Physical measurement reference values are helpful to manage patients, conduct surveillances and monitor and evaluate interventional activities. Such valuable data at a community level however, are almost non-existent in Ethiopia. The objective of this study was to determine anthropometrics and blood pressure in "apparently healthy individuals" in community settings.

METHODS

A population-based cross-sectional survey was conducted from September 2008 to January 2009 at Gilgel Gibe Field Research Center, Southwest Ethiopia. Blood pressure, height and weight were measured using Automatic Blood Pressure monitor, stadiometers and digital weight scales respectively. Waist and hip circumferences were measured using measuring tapes. BMI was computed as weight in kg divided by square of height in meter of individual (kg/m(2)). Waist to hip circumference ratio (WHR) was calculated by dividing the waist circumference to hip in centimeter. Data were entered into Epidata and analyzed using SPSS for Windows version 16.0 and STATA 11.

RESULTS

The mean systolic/diastolic blood pressures for men and women were 115.8/73.4 and 112.6/72.9 mmHg respectively. The mean BP values showed increasing trend with age for both sexes. The mean heart rate for men and women were 78.6 and 84.7 beats per minute, respectively. The mean weight and height values in all age groups, waist circumference value in 35 years and above were significantly higher (p < 0.001) for men, while the mean values for hip circumference in under 35 years and body mass index in under 45 year age groups were significantly higher (p < 0.025) for women. The mean body mass index for age group 15-24 (18.1 kg/m(2)) was significantly lower (p < 0.001) than the other age groups in men; whereas in women those 55+ years had significantly (p < 0.001) lower mean body mass index compared to the other age groups. The Waist to Hip circumference (WHC) ratio increased from 0.87 for age 15-24 years to 0.92 for those age 55 years and above. Comparison with findings in other parts of the world showed that Ethiopians (both sex) had low mean weight, waist and hip circumferences, but high body mass index.

CONCLUSION

The study showed that the physical measurement values are different from the other regions of the world. The use of other reference values in evidence based practices may result in under detection of risk groups.

Population based survey of chronic non-communicable diseases at gilgel gibe field research center, southwest ethiopia

BACKGROUND

Chronic Non-communicable Diseases are increasingly becoming more prevalent and burden to the health care system in developing countries including Ethiopia. However, evidences showing the magnitude of the problem in those countries are scarce particularly in a community setting. The objective of this study was to determine the magnitude of chronic non communicable diseases in a community.

METHODS

A population-based cross-sectional study was conducted in Gilgel Gibe Field Research Center from late September 2008 to end of January 2009. A random sample of 4,469 individuals aged 15-64 years was studied. Data on characteristics and chronic symptom inventories were collected by interviewing study participants. Blood pressure was taken three times from each individual and blood sugar and lipid levels were determined after an overnight fasting. Data were analyzed using SPSS for Windows version 16.0 and STATA 11.

RESULTS

The overall prevalence of CNCD was 8.9% (7.8% men and 9.8% women). The specific observed prevalence were 0.5% for diabetes mellitus (DM), 2.6% for hypertension, 3.0% for cardiovascular diseases, 1.5% for asthma and 2.7% for mental illness. In addition 3.1% and 9.3% of the study population had been informed to have DM and hypertension respectively.

CONCLUSION

There is a high prevalence of CNCD among the study population indicating an immediate need for preventive action and also warrant further nationally representative study.

Prevalence and predictors of intestinal helminthiasis among school children in jimma zone; a cross-sectional study

BACKGROUND

Globally, millions of people suffer from intestinal parasitic infections. These infections are among the most common resulting in considerable morbidity and mortality. In Ethiopia and particularly in Jimma and its surroundings intestinal parasitic infections are highly prevalent because of low living standards and poor environmental sanitation. The objective of the survey was to determine the prevalence and predictors of intestinal parasitosis among school children in four woredas of Jimma zone surrounding Gilgel gibe hydraulic dam and serve as a base line data to help evaluate health promoting activities for the future and monitor those already delivered to the community.

METHODS

A cross-sectional study was carried out in October, 2008 in four Woredas of Jimma zone bordering Gilgel Gibe Dam. Children attending grades 1-8 in the schools located within 10 Kms ofthe Dam in the four bordering woredas and those living 30 Kms away from the shore line were the study subjects. Six hundred twenty four and 321 children were selected from the schools around Gilgel Gibe dam and from the schools in Bulbul, respectively. Data on background of participant was collected and stool specimen collected and processed. Data were filtered and entered into computer then analyzed using SPSS for windows version 13.0.1.

RESULTS

Of the 937 selected individuals, 855 participated in the study giving a response rate of 91.2%. The prevalence of intestinal parasitosis was 47.1% where 174 (20%) had Ascaris lumbricoides monoinfection; 4.3% had dual infection involving Ascaris lumbricoides and hookworm and 0.2% had triple infection but all the infections were of light intensity. In addition, there was no association between prevalence of intestinal parasitosis with availability or regular use of latrine and clinical symptoms.

CONCLUSION

The prevalence and intensity of intestinal parasites in the study area is lower than national, urban and rural setting of Jimma zone. These might be due to a better awareness of the study community on prevention of intestinal parasitosis following increased health promoting activities in the area, delivered through various activities of Jimma Public health training program.

Impact assessment of gilgel gibe hydroelectric dam on schitosomiasis: a cross sectional study in southwest ethiopia

BACKGROUND

Intestinal schistosomiasis is prevalent in East Africa including Ethiopia. Constructed five years back, Gilgel Gibe dam is suspected to harbor the intermediate host for transmission of schistosomiasis. The objective of this study was to determine the prevalence of intestinal schistosomiasis and risk factors among school children.

METHODS

A comparative cross-sectional study was carried out in October 2008 in four Woredas bordering Gilgel Gibe dam, within 10 kilometers, and Bulbul, which is 30 Kms away from the dam. Children attending grades 1-8 in the schools located adjacent to the dam constituted the cases and those living in Bulbul constitute the controls. Using Epinfo version 6.0 for cross-sectional study, a sample size of 937 was determined. Sample size allocation was done 2:1 for cases and control. After interview, stool sample was collected and analyzed. Screening for the presence of intermediate host and physiochemical analyses of selected water bodies along the major water contact sites of the reservoir was also done Data were entered into computer and analyzed using SPSS for windows version 13.0.1.

RESULTS

Out of 624 sampled cases and 312 controls, 585 and 270 participated in the study giving a response rate of 93.8% and 86.5%, respectively. Four hundred seventy four (81.0% of the cases and 203 (75.2%) controls use latrine regularly. On stool examination, 406 (47.5%) children, 295 (50.4%) cases and 111 (41.1%) controls) were positive to intestinal parasites but only two children, both from the control groups, were positive for Schistosoma mansoni. The three river water samples on which malacological survey was done had similar physicochemical characteristics in many ways except high conductivity, pH and percent of dissolved oxygen concentration (milligram per liter) at one site where uninfected Biomphilaria Pfeifferi was found

CONCLUSION

The study revealed that schistosomiasis is not yet a problem at Gilgel-Gibe dam. But, continuous surveying is required as the intermediate host is prevalent, the water bodies are suitable for the intermediate host and cases of schistosomiasis are identified 30 kms away the dam, in control area.

Ototoxicity of artemether/lumefantrine in the treatment of falciparum malaria: a randomized trial

Background

Due to increasing drug resistance, artemisinin-based combination chemotherapy (ACT) has become the first-line treatment of falciparum malaria in many endemic countries. However, irreversible ototoxicity associated with artemether/lumefantrine (AL) has been reported recently and suggested to be a serious limitation in the use of ACT. The aim of the study was to compare ototoxicity, tolerability, and efficacy of ACT with that of quinine and atovaquone/proguanil in the treatment of uncomplicated falciparum malaria.

Methods

Ninety-seven patients in south-west Ethiopia with slide-confirmed malaria were randomly assigned to receive either artemether/lumefantrine or quinine or atovaquone/proguanil and followed-up for 90 days. Comprehensive audiovestibular testing by pure tone audiometry (PTA), transitory evoked (TE) and distortion product (DP) otoacoustic emissions (OAE) and brain stem evoked response audiometry (BERA) was done before enrolment and after seven, 28 and 90 days.

Results

PTA and DP-OAE levels revealed transient significant cochlear hearing loss in patients treated with quinine but not in those treated with artemether/lumefantrine or atovaquone/proguanil. TE-OAE could be elicited in all examinations, except for three patients in the Q group on day 7, who suffered a transient hearing loss greater than 30 dB. There was no evidence of drug-induced brain stem lesions by BERA measurements.

Conclusion

There was no detrimental effect of a standard oral regimen of artemether/lumefantrine on peripheral hearing or brainstem auditory pathways in patients with uncomplicated falciparum malaria. In contrast, transient hearing loss is common after quinine therapy and due to temporary outer hair cell dysfunction.

The problem of epilepsy and its care in rural Ethiopia

BACKGROUND

Jimma University Hospital (JUH) in south west Ethiopia has been running an integrated rural chronic disease programme since 1999, focusing on treatment of epilepsy, diabetes and heart disease.

OBJECTIVE

The purpose of this review is to compare clinical data of the epilepsy patients with those previously published from a similar programme in Gondar university, in the north west of the country.

METHOD

In November 2005, we identified a total of 1,250 patients with epilepsy from the JUH study with case records for analysis. Clinical data are documented in the case records using a structured questionnaire and follow-up chart. We entered the data into SPSS software and performed descriptive analyses.

RESULTS

The age of the patients was weighted towards teenage years and young adult life, very similar to that seen in Gondar. The majority of those presenting to the clinic were male (M:F = 1.6:1) and educational level in rural communities was poor. The seizure history was very similar to that observed in Gondar. The average age at onset of unprovoked seizures was 13 years, and only 35% of patients presented within six months of their first seizure. A family history was found in 8% compared with 24% in Gondar. Other risk factors for epilepsy such as previous intracranial infection, head injury and perinatal factors were reported more frequently by patients from Jimma. Status epilepticus was reported by 2.7% in Jimma and 2.0% in Gondar. 10% in both Jimma and Gondar had received burns as a result of seizures. The psychosocial impact of epilepsy was substantial; 24-47% of patients were affected in some way. Default from follow-up was high in both Jimma (40%) and Gondar (62%).

CONCLUSION

The JUH data show good general agreement with Gondar university, suggesting that the areas have comparable populations of people with epilepsy. Despite the large number of patients registered at the health centres, there is still a considerable gap between those who suffer from the condition and those who actually get treatment with phenobarbitone. Future work will need to address this shortfall and increase the availability of this inexpensive and effective treatment.

A primary healthcare approach to the management of chronic disease in Ethiopia: an example for other countries

Chronic non-communicable diseases such as epilepsy, diabetes, cardiac disease and hypertension represent a growing but neglected burden in developing countries. Rural sufferers, distant from health facilities, bear this most acutely. In response, a community care programme has been developed at Jimma University Hospital and its allied health centres in rural southwest Ethiopia. This involves general duty nurses at rural health centres being trained to provide care for chronic disease patients, with regular supervision from the hospital physicians. The programme allows treatment to be provided away from the main hospital so that those who cannot afford to travel can access care near their homes. Improved access increases the request for care, and helps to address the large unmet need for chronic disease treatment. This is a good model in which rural healthcare delivery through a team can bring widespread benefit. In this article chronic disease care is discussed with a particular focus on diabetes and epilepsy. The model can be replicated in more or less developed countries and may also be relevant for HIV care.

Pattern of widal agglutination reaction in apparently healthy population of Jimma town, southwest Ethiopia

BACKGROUND

Typhoid fever is leading cause of morbidity in developing countries including Ethiopia. Isolation of Salmonella Typhi by culturing, from blood or other source, is the surest way of making laboratory diagnosis. However, in resource-limited countries, the Widal agglutination test provides cheaper and easy alternatives, though inappropriate technique and interpretation continue to cast a shadow on its usefulness.

METHODS AND MATERIALS

A cross-sectional study was carried out during the period of February to May 2004 to determine the baseline antibody tube titration and slide agglutination pattern to Widal antigen and the usefulness of rapid slide agglutination test for diagnostic purposes among apparently healthy population of Jimma town, southwest Ethiopia. Blood samples were collected from subjects who gave their consents after thorough explanation of the procedure and the purpose of the study. The study participants were selected by a systematic random sampling technique. The sera of subjects were tested for Widal agglutination by an experienced laboratory technologist according to the standard procedural protocol-using antigen from Chronolab AG, Switzerland Data were cleaned edited and entered in to a computer and analyzed using SPSS for window version 11.0. Major results were expressed as 95% probability limit, and validity scoring; agreement test (Kappa) was determined.

RESULTS

The result indicated that among the apparently health population, almost all the blood tested showed some titer of the antibody and reactivity of agglutination slide tests. The 95% probability limit (mean + 2SD) for anti H and anti O antigen titration was 1:276.89 and 1:207.89, respectively. These figures are closer to a cut-off titer of 1.320. There was a fair agreement between slide agglutination test and tube titer for 0 antigen (Kappa=0.225) and a poor agreement for H antigen (Kappa=0.066). When agglutination test result of highly reactive (+4) and titration of 1:320 were used, few cases became reactive indicating the need to raise the cut-off value to these points respectively.

CONCLUSION

It is recommended that if Widal test is to be used for the clinical work up of typhoid fever in adult population, a cut-off value highly reactive (+4),for rapid slide agglutination and a titer of 1.320 and above for tube titration test be used. At the cut-off values indicated above, Widal test has low sensitivity and positive predictive value and high specificity and negative predictive values. This makes the test useful support to clinical suspicion but unlikely means ofJscreening.

Fibrocalcific pancreatic diabetes in a young Ethiopian man

An eighteen year old Ethiopian patient was admitted to Jimma teaching hospital, after presenting with classical hyperglycemic symptoms associated with abdominal pain, chronic diarrhea, cachexia, and radiological appearance of extensive pancreatic calcification. These clinical and radiologic findings correlated with the well-described entity of Fibrocalcific pancreatic diabetes, which has never been reported from Ethiopia before.

Trends of acute myocardial infarction admissions over a decade, Tikur Anbessa Hospital

This is a case series analysis undertaken to evaluate the importance of acute myocardial infarction (AMI) as a cause of admission at the Tikur Anbassa medical intensive care unit (MICU) and the trend of that importance over a decade (1988-1997). Clinical presentations and the frequencies of major coronary risk factors in the individual patient were also assessed for the later half of the decade (1993-1997). In the decade under study 2313 patients were admitted to MICU according to its register. Overall AMI was the third commonest cause of admission and accounted for 8.8% (N = 203) of all MICU cases. AMI annual admissions increased consistently over the years. Of the 122 AMI admissions during the second half of the decade, 92 charts were available for detailed analysis. 86% (79/92) fulfilled the stated criteria for the diagnosis. The mean age of these patients was 55.1 +/- 13.0 years. Males constituted 82% of all AMI cases. Eighty seven percent (69/79) of the cases were first admissions with the diagnosis of AMI. Ninety-four percent (74/79) of them were brought to the emergency room due to chest discomfort and 20% were in frank pulmonary oedema. Nineteen percent died in hospital. 81% and 34% of the patients had one or more and two or more major coronary risk factors excluding age and gender respectively. Raised total cholesterol and hypertension were commonest risk factors being reported in 69% and 47% of AMI patients respectively. In conclusion, this study has demonstrated that AMI is indeed on the rise at least at Tikur Anbassa Teaching Hospital, and possibly at other health institutions. The conventional coronary risk factors seem to operate in the Ethiopian series as well. The study highlights the need for coronary risk factors surveys at least in the susceptible population group to assess the gravity of the problem.
