Abstract
The disease burden from noncommunicable diseases (NCDs) in Africa is rapidly increasing based on projections from a limited number of reports. In the absence of national health surveys in Zimbabwe, all data nationally generated between 1990 and 1997 were analyzed. From 1990 to 1997, prevalence rates (expressed per 100,000 people) of hypertension increased from 1000 to 4000, rates of diabetes increased from 150 to 550, and rates of cerebrovascular accidents (CVA) increased from 5 to 15. The case fatality rate (CFR) for CVA decreased substantially during the period of study, implying improved case management of the disease, while the CFR for most other diseases did not change significantly throughout the study period. The observation of increased prevalence of some NCDs during the study period was corroborated by findings from a blood pressure survey subsequently conducted in an urban environment of Zimbabwe, which revealed a hypertension (blood pressure > or =140/90 mm Hg) prevalence of 35% in women and 24% in men. In spite of the limitations of the centrally generated hospital-based data, its analysis is still valuable. Countries are therefore encouraged to utilize this easily accessible resource for policy formulation and resource mobilization.
    • "In our study some epidemiological and biological factors have shown a significant statistics correlation with non-Hodgkin lymphoma (age equal or above 50 years, inguinal location, multifocal location, painful character and leukocytosis) and lymph nodes reactive hyperplasia (age less than 50 years, inguinal location and painful character) as pathologic diagnosis. Looking at the epidemiological profile where change of life style and diet habits in urban African areas is expected in the future [22] and diagnosis means found in Lubumbashi health structures, we believe that parameters studied above would serve as elements to orientate management of patients with superficial lymphadenopathy in our area and reinforce directives by the National Program against Tuberculosis (NTP) to diagnose TB lymphadenopathy which is currently based on biological and clinical crite- ria [23]. Befits, nevertheless, be noted that the invasive aspect of excision-biopsy didn't allow an easy patient compliance and the financial and technical accessibility defect was also a difficulty encountered throughout our study.

    [Show abstract] [Hide abstract] ABSTRACT: Introduction: Superficial lymphadenopathy is a frequent reason for consultation in Internal Medicine. The diagnosis approach even done by a meticulous clinical examination has to be completed with investigations such as medical imagery and pathologic study. In low-income countries like Democratic Republic of Congo, means for proper diagnosis remain hardly accessible for some classes of the society. Thus, our study aims to describe socioeconomic , clinical and biologic parameter that can give diagnosis orientation in patients with superficial lymphadenopathy as observed in the department of internal medicine at the University of Lubumbashi Clinics (DR Congo). Patients, Material and Method: This is a descriptive, transversal study on superficial lymphade-nopathy observed for a period of 24 months from November 2013 to October 2015 at the University of Lubumbashi Clinics. Parameters studied included gender, age, localization and clinical characteristics of superficial lymphadenopathy; biologic parameters and pathologic diagnosis were determined by lymph nodes biopsy. Results: 36 patients data were captured and non-Hodgkin lymphoma is the most frequent pathologic diagnosis (47.20%) followed by reactive hyperplasia (27.80%) and infectious lymphadenitis (19.40%). Some of the variables studied presented a significant statistical association and included age ≥ 50 years old (p = 0.0247), inguinal location (p = 0.0053), multifocal location (p = 0.0063), sensible character (p = 0.0391) and leukocytosis (p = 0.0022) for non-Hodgkin lymphoma and variables like age below 50 years (p = 0.0345), inguinal location (p = 0.0299) and sensible character (p = 0.394) for reactive hyperplasia. Conclusion: The C. Kakisingi et al. OALibJ | most frequent aetiology seen in this very is non-Hodgkin lymphoma (47.2%) followed by lymph node reactive hyperplasia (27.8%) and infectious lymphadenitis. The emergence of non-commu-nicable diseases in both developed countries as low income is growing and special emphasis should be given to this growing scourge. Cancer is one of the most frequent pathologies and non-Hodgkin lymphoma is one of the deadliest cancer types. And having epidemioclinic and biological parameters in the absence of appropriate diagnosis means could contribute to improving the prognosis of lymphadenopathy patients in low-income countries like the Democratic Republic of Congo.

    • "In Zimbabwe, three consecutive readings at least 4 hours apart are used for diagnosis after which a Medical Doctor can commence treatment. However a single systolic blood pressure (SBP) above 180 mmHg or a diastolic blood pressure (DBP) above 110 mmHg is indication for treatment [11]. Trend analysis of hypertension between Mazowe District, Mashonaland Central Province and Zimbabwe from 2004 to 2011 showed that the district trend is slowly declining out of keeping with the national trend (Figure 1).

    • "Diabetes was ranked fourth (after hypertension, asthma and epilepsy) amongst the non-communicable diseases (NCDs) recorded in outpatient visits in Zimbabwean public hospitals in 2006 (Ministry of Health and Child Welfare 2009), National health survey data from which to examine the burden of diabetes in Zimbabwe are limited (Mufunda et al. 2006); one sub-national health survey conducted in three of the ten provinces estimated diabetes prevalence to be 10.2 %, with females more likely to report a history of diabetes compared to males (Hakim et al. 2005). Another study of central-hospital based data estimated that the prevalence of diabetes (expressed per 100,000 people) had increased from 150 to 550 from 1990 to 1997(Mufunda et al. 2006). Resource limitations mean that there are no comprehensive population surveys evaluating the prevalence of diabetes throughout Zimbabwe, and estimates from the IDF have been based on a single 2005 sub-national survey (International Diabetes Federation 2013) and may thus not be nationally representative.

    [Show abstract] [Hide abstract] ABSTRACT: Objective: Diabetes appears to be a growing problem in the African region. This study aims to estimate the prevalence of diabetes in Zimbabwe by collating and analyzing previously published data. Methods: Systematic review and meta-analysis of data reporting prevalence of diabetes in Zimbabwe was conducted based on the random effects model. We searched for studies published between January 1960 and December 2013 using MEDLINE, EMBASE and Scopus and University of Zimbabwe electronic publication libraries. In the meta-analysis, sub-groups were created for studies conducted before 1980 and after 1980, to understand the potential effect of independence on prevalence. Results: Seven studies were included in the meta-analysis with a total of 29,514 study participants. The overall pooled prevalence of diabetes before 1980 was 0.44 % (95 % CI 0.0–1.9 %), after 1980 the pooled prevalence was 5.7 % (95 % CI 3.3–8.6 %). Conclusions: This study showed that the prevalence of diabetes in Zimbabwe has increased significantly over the past three decades. This poses serious challenges to the provision of care and prevention of disabling co-morbidities in an already disadvantaged healthcare setting.
