Abstract:
Introduction: The causes of superficial lymphadenopathy are diverse and their prognosis is often unknown. The diagnosis of superficial lymphadenopathy remains a challenge because, alone, its clinical picture doesn’t allow differentiating between an infectious disease and a non-transmissible disease. The aim of this study is to describe epidemiological, clinical and pathologic aspects of superficial lymphadenopathy observed in the internal medicine department at the University of Lubumbashi Clinics (DR Congo). Patients, Materials and Methods: This is a descriptive and transversal study on superficial lymphadenopathy observed over a period of 24 months from November 2013 to October 2015 at the University of Lubumbashi Clinics. Parameters studied were gender, age, clinical particular of superficial lymphadenopathy and associated patient clinical signs and pathology of these lymph nodes biopsy. Results: 36 patients’ data were identified with a sex ratio M/F = 1.76 and a mean age of 42.47 ± 15.64 years. 75% of patients had lymph nodes tumefaction as the main complaint during consultation and 61.1% had a poor general condition marked by fever. 27.8% were HIV positive and cervical lymphadenopathy was the most frequent. As for the pathologic diagnosis, non-Hodgkin lymphoma was the most frequent diagnosis (47.2%) followed by reactive hyperplasia (27.8%) and infectious lymphadenopathy (19.4%). Conclusion: The most frequent cause of lymphadenopathy in our study was non-Hodgkin lymphoma (47.2%) followed by lymph nodes reactive hyperplasia (27.8%) and infectious lymphadenitis. Lymph nodes biopsy plays an important role in confirming superficial lymphadenopathy diagnosis. It should be the basic procedure to diagnose extra pulmonary tuberculosis in the DRC National Program against TB.

Abstract: Introduction: Malaria infection and HIV infection are major public health issues in several parts of the world. Together they have caused more than a million deaths per year. Africa, and Sub-Saharan in particular are the most affected. Our study objective is to determine the prevalence of Malaria/HIV co-infection and describe its immunological, virological, parasitic and biological characteristics. Methodology: This is a descriptive, transversal and multi centric study done on 18 years old and above HIV positive patients, for a period extending from December 2008 to October 2009 in 5 different HIV treatment centres. Parameters studied were gender, age, CD4 count, viral load, parasite density and haemoglobin level. The HIV diagnosis was made according to the AIDS National Program and malaria according to the Malaria National Program. Statistic analyses were done using Epi Info 7 software and the Yates corrected Chi Square test or the Fischer Exact test (when recommended) was used to check any link between different parameters studied. Statistical significance was fixed at <0.05. Results: 405 HIV seropositive patients were compiled. The malaria prevalence in these patients was 6.9%. Majority of co-infected patients were aged between 26 and 49 years (67.9%), and had a CD4 count <200 μl (67.9%), a parasitic density <10,000 trophozoites/μl (75%) and an Hb level <11 g/dl. With regards to correlations between co-infected patients parasitic density and the CD4 count, viral load and Hb level, none of the studied parameters showed any statistic significance difference. Conclusion: A prevalence of 6.9% among HIV/malaria co-infected patients and 67.7% of these patients had a CD4 count less than 200 cells/μl. Thus, both national programs must promote an early testing for HIV infected patients and reinforce preventive measures in the management of malaria.

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 socio-economic, 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 lymphadenopathy 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 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-communicable 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.

Abstract: Background: Malaria in pregnancy is associated with many negative outcomes for the woman,foetus and neonate. Intermittent preventive treatment during pregnancy (IPTp) using three doses of sulfadoxine/pyrimethamine (SP), insecticide-treated mosquito nets (ITNs) and indoor residual spray (IRS), constitute the main strategies used to prevent malaria. The aim of this study is to evaluate the effectiveness of these strategies for the reduction of malaria prevalence in pregnant women. Methods: A questionnaire on socio-demographic information, history of malaria during current pregnancy and prevention strategies used was administered to 450 consecutive patients admitted into labour wards at three local clinics. From the antenatal cards, information was collected on the last menstrual period, date of each dose of SP taken, gravidity, and HIV status. A blood slide to detect Plasmodium was then collected from each woman after consent. Results: Of the participants in the study, 2.4% had a positive blood slide at term and 15.8% reported malaria during pregnancy. All the participants took at least one dose of SP with 87.6% completing the stipulated three doses. The mean gestational ages for each dose were 22.1 (SD 4.6), 29.1 (SD 4.4)and 34.4 (SD 3.9) weeks for the first, second and third dose respectively. With regard to ITNs, 79.5% had one, but only 74.1% used it regularly. IRS was completed in all three of the clinics’ catchment areas. Only 23.4% used commercial insecticide. Conclusion: The measured prevalence of malaria at term in Ndola was remarkably low, although the self-reported rate during pregnancy was still high. The national targets for accessing IPTp were exceeded, although the timing of each dose needs to be improved. Access to ITNs was high, but usage needs to increase.

Generating Net Forces from Backgrounds of Randomly Created Waves  [PDF]

Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.516158
Abstract: We examine the possibility of generating net forces on concave isolated objects from backgrounds consisting of randomly created waves carrying momentum. This issue is examined first for waves at the surface of a liquid, and second for quantum vacuum electromagnetic waves, both in relation with a one-side-open rectangular structure whose interior embodies a large number of parallel reflecting plates. Using known results about the Casimir-like effect and the original Casimir effect for parallel plates, we explain why and how such rectangular hollow structures should feel net oriented forces. We briefly describe real systems that would allow testing these theoretical results.
Wave-Particle Duality in Einstein-de Broglie Programs  [PDF]

Abstract: The standard model of particle physics forms a consistent system for universe description. After following quantum mechanics, it derives particles from relativistic quantum fields. Since it does not include gravitation, it describes only one aspect of the universe. In extension of general relativity, Einstein had proposed a symmetrical and complementary approach of physics. In his program, he privileged a relativist field based on representations for physical phenomena, before a precise mathematical description. It allows completing and unifying the universe description, like both eyes for relief vision, and both ears for stereophonic audition. We propose to show it with many simple examples.
Gravitation and Electromagnetism Conciliated Following Einstein’s Program  [PDF]

Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.65072
Abstract: The Einstein’s program permits to conciliate gravitation and electromagnetism. Besides the standard model, it forms a consistent system for universe description, founded upon a scalar field propagating at the speed of light c. Matter corresponds to standing waves. Adiabatic variations of frequencies lead to electromagnetic interaction constituted by progressive waves. Classical domain corresponds to geometrical optics approximation, when frequencies are infinitely high, and then hidden. As interactions for matter, Gravitation and Electromagnetism derive from variations of its energy E = mc2. Electromagnetic interaction energy derives from mass variation dE = c2dm, and gravitation from speed of light variation dE = mdc2. Contrarily to gravitation, only electromagnetic interaction serves as a bridge between classical and quantum frames, since it leans directly upon the wave property of matter: its energy dE = hdν = c2dm derives from variations of matter energy E = hν = mc2.

Medical Journal of Zambia , 2011,
Abstract: Reported here is the case series of six infants presenting with immune reconstitution syndrome following the initiation of antiretroviral therapy (ARV). The infants had no BCG scars at the time of starting ARVs and the mean duration of appearance of the cold abscess / lymphadenitis on the ipsilateral side of the BCG site was 2 – 8 weeks. Mycobacterial speciation studies of the fine needle aspirate material showed Mycobacterium Bovis, BCG strain. Two of the patients had to require antimycobacterial therapy.

Abstract: Health worker salaries in Zambia are low by any standard. In recent times there have been real reductions in the salaries of health workers. This has resulted in significant attrition in the public sector as health workers are attracted to the private sector or leave Zambia entirely, leaving a large deficit in public sector health workers. In this study we examine the relationship between health worker incomes and their satisfaction and motivation. Cross-sectional data collection was undertaken using both quantitative and qualitative methods. A refined survey instrument was used for the quantitative data method. Document review (past and current records) was employed for the qualitative method. Data was collected in three regions that represent extremes in overall remuneration and benefits. Lusaka represented the favourable area while Monze and Nyimba represented less favourable areas for study in Zambia. There are hefty disparities between different health workers. There are also enormous salary differentials for the same workers between the public and private sectors. These salary differentials explain the experience of public to private “traffic” of health workers as well as casual private sector work by public sector health workers. In addition, there are negligible efforts by government to reduce the benefits gaps among key public health cadres. The low incomes received by public health workers in Zambia have many negative implications: it begets absenteeism, results in low output, poor quality health care, and the departure of health workers to the private sector and overseas.
