OCLC Number/Unique Identifier: 9406521355
Introduction: Preeclampsia constitutes a public health problem in our region. According to the WHO, it is the third cause of maternal mortality after severe hemorrhages, infections and is responsible for morbidity and high fetal mortality. The aim of this study was to improve on the management of severe preeclampsia at the University Hospital Center of Mother and Child (UHCMC) in N’Djamena.Patients and method: It was a prospective and descriptive survey of 3 years duration, from January 01st, 2017 to December 31st, 2019. Included in our study were, all patients admitted for severe preeclampsia and agreed to participate in the study. Epidemiological, clinical, therapeutic and prognostic studies were conducted. The data collected was analyzed using SPSS 18.0 software.Results: During the study period, 13599 pregnant and parturients were admitted to the Gynecology-Obstetrics department of the UHCMC, among whom 406 cases of severe preeclampsia, with a frequency of 2.9%. The patients were young (23.2 years), married (96.3%), primipara (61.3%), referred (64.3%) without antenatal care in 47.9% of cases. Functional signs were dominated by headaches with 34.0% of cases. The proteinuria was ≥ 3 crosses in 83.7% of cases. Patients had received magnesium sulfate in 98.3%, the delivery mode was cesarean in 64.0% of cases. Principal morbidity was eclampsia (40.8%) and fetal was prematurity (36.4%). Maternal lethality was 11.1% and fetal mortality was 19.9% cases.Conclusion: Severe preeclampsia is frequent in the UHCMC in N’Djamena. It is responsible for high maternal and fetal mortality. The practice of quality antenatal care, could prevent the occurrence of complications and improve the maternal-fetal prognosis.

Acute Kidney Injury (AKI) is defined as an abrupt decrease in kidney function within hours to days and is caused by multiple factors. Community-acquired AKI (CA-AKI) is common in developing countries, and it is crucial to bring awareness about its epidemiology and simple preventive strategies that can tackle this potentially serious complication. Infections, use of over-the-counter medicines, traditional herbal remedies, animal (and insect) bites, and pregnancy-related complications are common causes of CA-AKI in developing countries. The incidence of vector-borne disease-related AKI and obstetric causes of AKI have decreased following better public health policies in most developing countries. Appropriate fluid management is critical in AKI, both in terms of prevention of development and progression of AKI. Timely initiation and de-escalation of fluid therapy are both equally important. Kidney replacement therapy (KRT) is indicated when AKI progresses to stage 3 and/or patients develop refractory fluid overload or electrolyte imbalances and/or uremic complications. Hemodialysis is the most common modality of KRT in adults, whereas peritoneal dialysis is the dominant modality in small children. Convective renal replacement therapy, such as hemofiltration, is increasingly used in critically sick patients with AKI and hemodynamic instability. To summarize, CA-AKI is a common, serious, and often preventable complication of certain conditions acquired in the community, and is, therefore, a matter of utmost concern from the public health perspective.
Review on epidemiology of bovine hemoparasites in Ethiopia
Published on: 29th April, 2022
A literature-based review was made to assess available information on bovine hemoparasites related to their epidemiology, distribution, and economic importance in Ethiopia. Babesiosis, anaplasmosis, cowdriosis, theileriosis, and trypanosomosis are the major hemo-parasitic disease of bovine in Ethiopia. Their adverse effects on the health of the animals can decrease production and productivity. Hemoparasites generally cause fever, anemia, jaundice, anorexia, weight loss, milk drop, malaise, swelling of lymph nodes, dyspnoea, diarrhea, nervous disorders, and death by affecting blood vessels and/or lymphatic system of the animal. Reports from different parts of the country displayed there is a high distribution of bovine hemoparastic disease throughout the country. Anaplasmosis, Babesiosis (redwater), Ehlichiosis (Heartwater), Theileriosis, and Trypanosomosis are the major hemoparasitic diseases with heavy economic losses. Their mode of transmission was by arthropod vectors ticks and flies. Applying effective vector control and using vaccines drugs are the two most important control methods for hemoparasites diseases. Also having knowledge of parasite life cycles, their biological vector, and the immune response of bovines to vectors and parasites were also used in the successful application of control strategies. Creating awareness of the mode of transmission, method of control, and prevention of hemoparastic disease of bovine to livestock owners were warranted to decrease the effect of the disease.
Determination of foot-and-mouth disease serotypes from naturally infected cattle by solid phase competitive ELISA (SPCE) techniques

OCLC Number/Unique Identifier: 9632304501
Objective: Foot and mouth disease (FMD) is a highly infectious and economically important disease affecting cloven-hoofed domestic and wild animals. Early diagnosis and serotyping of the agent are very important to effectively design and implement the control approach. This study was conducted on serum samples collected from Amhara, Tigray, Oromia and Addis Ababa between October 2018 to February 2020. The animals were kept under a semi-intensive to an extensive system of rearing. Serum samples with low OD values (positive) using competition NSP-ELISA were subjected to serotyping ELISA. Results: In the present study, three serotypes were identified from 186 NSP ELISA positive sera of which 156 serotype O, 40 serotypes A and 28 serotype SAT2. In this analysis, multiple serotype infection was observed which is why the number of serotypes was beyond the samples analyzed. Among 23 samples from Addis Ababa 10, 3 and 5 were O, A and SAT2 serotypes respectively, while in samples from the Oromia region 12 were O and 3 were SAT2 serotypes. From the Amhara region, 99 samples analyzed were found to be serotype O and SAT2 in 7 of the serum samples. From the Tigray region, 30 samples were seen to have Serotype O infection, whereas 13 of them were SAT2. The proportion of serotypes identified based on the production system practices was also found that semi-intensive production takes the largest share in all three serotypes followed by extensive production. Generally, early determination of the serotype from past infection helps to aware of the epidemiology as well as the infection immunity of the herd/individual animals.
A relevant article, white papers and other documents concerning the mRNA vaccine: an interesting collection useful to better understand some phenomena and to generate hypotesys
Published on: 13th October, 2022
The aim of this work is to report some interesting references and documents related to the mRNA vaccine. Every cited reference can act as an instrument to better understand what some independent researchers find: this work is mainly focused on the public debate related presence/absence of graphene derivates in some vaccine vials for COVID-19. Relevant classic articles White Papers or other kinds of a document are useful instruments to better clarify some crucial aspects of this infectious disease, its epidemiology and the efficacy of the measure adopted (preventive, therapeutic, or vaccine).If the reviewed article show an intrinsic recognized international value other kinds of source like a White Paper or other documents can be of interest to generate hypotheses or to open public discussion on crucial topics. For this reason, it is useful to use this method also in the discussion related to impurity profiles in new innovative bio-pharmaceuticals like the mRNA vaccine. The fact that this product was introduced with an emergency authorization, whit reduced the time of experimentation and due to the lack of official quality information related to some raw materials used authorizes us to use also this method.Even if the international official regulatory agency does not find this substance in the control for release of the lots it is interesting to more deeply investigate what funded by an independent researcher in some vials of vaccine or sample patient’s blood after vaccination. This reference even if not a smoking gun the same can stimulate the reasoning about the general concept involved. It is needed, to read this work, to consider the intrinsic limitation of some of the study research reported (White Paper) or the other documents.
Jejunal adenocarcinoma, a rare cancer of the gastrointestinal tract: a comprehensive review discussion epidemiology
Published on: 24th November, 2022
Malignancy of the small bowel is exceedingly rare, accounting for 3% - 5% of all gastrointestinal malignancies [1-3]. However, in recent years because of improved diagnostic accuracy, the incidence of small bowel cancer is rising. It is estimated that 10, 470 new cases of primary SI cancer will be diagnosed in the US with 1450 cancer-related deaths [4]. The most frequent histologic types of small bowel malignant tumors include adenocarcinomas, carcinoids, lymphomas, and sarcomas. Adenocarcinoma of the small intestine is the second most common histologic type of SI cancer. The most frequent location of SI adenocarcinoma is the duodenum (57%), followed by the jejunum (29%) and ileum (13%) [5]. SI cancers are more common in men than women [6]. They occur more commonly in the African-American population and after 60 years of age [7].
Association between the victim’s menstrual cycle phase and genital injuries following sexual assault
Published on: 2nd May, 2023
Background: It is unknown what effect the menstrual cycle can have on the susceptibility to trauma following sexual assault. Objectives: To compare the incidence of genital injuries following sexual assault in women with relationship to the three phases of the menstrual cycleMethods: The design was a retrospective, cohort analysis set in a community-based nurse examiner program over a five-year study period. Sexual assault victims were between the ages of 13 - 40 years and agreed to a forensic examination. The menstrual cycle was divided into three phases: follicular, luteal and menses phase. The primary outcomes were the frequency and type of genital injuries documented in relation to the different phases of the menstrual cycle.Results: Case files of 1376 cases of sexual assault were reviewed; 682 (49.6%) met the inclusion criteria. A total of 220 victims (32.3%) were in the follicular phase, 361 (52.9%) were in the luteal phase and 101 (14.8%) were in the menses phase. The three groups were comparable in terms of demographics, assault characteristics, and overall frequency of non-genital injuries. Assault victims in the follicular phase of the menstrual cycle had significantly more documented genital injuries (72.3%; 95% CI 66.4 - 78.2) compared to the luteal phase (64.0%; 95% CI 59.0 - 68.9) and the menses phase (58.4%; 95% CI 48.8 - 68.0). Conclusion: Forensic examiners documented more genital injuries in the follicular phase of the menstrual cycle. Sex hormones may have confounding effects through influences on vaginal epithelial and mucosal integrity.
Human Monkeypox Virus Severity
Published on: 16th June, 2023
Monkeypox is a sylvatic zoonotic sickness that initially affected tropical rainforest areas in the west and vital Africa earlier than spreading to other places. Its miles carried with the aid of the Monkeypox virus member of orthopoxvirus circle of relatives. The clinical features of the infection resembles to smallpox. The primary animal to human transmission is the cause of most people of human Monkeypox ailments. Severe rodent species and non-human primates function hosts for the virus. Transmission can manifest with infected people, animals or objects into contact with bodily fluids, sores on the skin or inner mucosal surfaces just like the mouth or throat, or breathing droplets. The incubation length for Monkeypox usually lasts 6 to 13 days, even though it could last as long as 21 days. The ailment is often self-proscribing, with signs and symptoms generally clearing up on their own inside 14 to 21 days. Signs can range from moderate to extreme, and lesions may be itchy or painful. Due to the discontinuation of recurring smallpox vaccination which supplied some pass- safety in past, populations have become more liable to Monkey pox. The outbreak of Monkeypox virus due to the fact that may additionally, 2022 has created a worldwide risk of the virus. In the present review, Monkeypox epidemiology, severity, therapeutics, vaccination and its transmission to non-endemic countries has been considered. Special care and guidelines may help in the containing in the spread of the infections to the non endemic countries.

Published on: 5th July, 2023
Introduction: The bone marrow aspirate examination is defined as a quantitative and qualitative study of bone marrow cells obtained by puncture and aspiration. Aim: Our objective was to evaluate the practice of this exam at Andrainjato Fianarantsoa University Hospital in order to improve its diagnostic relevance.Method: This is a prospective and descriptive cross-sectional study of all bone marrow aspirates performed at the Andrainjato Fianarantsoa University Hospital Madagascar, during 18 months, from January 2021 to June 2022.Results: Forty-two bone marrow aspirate examinations were performed during the study period, among the 338 requests for hematological analysis received, representing a percentage of 1.26%. The average age of the patients was 32.17 years, with a sex ratio of 2.5. The prescription was of hospital origin in 83.3% of patients, motivated by the disturbance of the blood count in 78.6% of cases. Thirty-three requests were evaluated as relevant prescriptions. Coupled with the realization of the bone marrow examination, the haemograms were pathological in 78.6% of cases. The result of the bone marrow aspirate showed normal marrow cytology (16.7%), reactive marrow (23.8%), pathological marrow (50.0%), and hemodiluted marrow (9.5%). Dysmyelopoiesis (33.3%), multiple myeloma (23.8%), and acute leukemia (19.0%) were the main pathologies found. The difficulties encountered were related to the poor quality of the equipment and the non-availability of other complementary explorations.Conclusion: The bone marrow aspirate examination is technically feasible at Andrainjato Fianarantsoa University Hospital despite the existence of difficulties. The commitment to the process of continuous improvement of quality would impose the improvement of the technical platform.
Psychosis in Parkinson’s Disease and Current Management Trends- an Updated Review of Literature
Published on: 26th July, 2023
As a neurodegenerative disorder, Parkinson’s disease (PD) is characterized by a combination of premotor, motor, and nonmotor symptoms. PD is commonly accompanied by psychosis, which is one of the commonest symptoms in the long run. As a result of Parkinson’s disease psychosis (PDP), symptoms can range from minor consequences of the disease (illusions, passage hallucinations, and presence hallucinations), to visual and nonvisual hallucinations and delusions. PDP is associated with a reduction in function and a reduction in quality of life as well. It is commonly believed that PDP is related to economic burden, and it has a significant impact on the utilization of long-term care services. The main focus should be on diagnosing, classifying, and managing PDP in an appropriate manner. As a first step in the management of PDP patients, the emphasis should be on identifying and treating any contributing medical factors, reducing or discontinuing medications that could cause or worsen psychosis, as well as nonpharmacological strategies and considering acetylcholinesterase inhibitors for treatment when dementia is present. A number of medications are being considered for use in PDP, including pimavanserin, quetiapine, and clozapine. The purpose of the current review is to provide a comprehensive understanding of the disorder in the general population with PD, including epidemiology, psychotic symptoms, risk factors, triggers, neuro-signaling pathways, diagnosis, and treatment of PDP.
Myxedema Coma and Acute Respiratory Failure in a Young Child: A Case Report
Published on: 26th July, 2023
Background: Myxedema is an extreme manifestation seen in patients with untreated hypothyroidism. It is a lethal endocrine emergency, which arises when a precipitating cause overwhelms the compensatory mechanisms of the hypothyroid state.Objectives: This case report aims to present a case of myxedema coma secondary to cretinism. It also aims to discuss how hypothyroidism leads to hypoventilation and eventually respiratory failure, as well as to discuss the epidemiology, pathophysiology, clinical manifestation, diagnosis, and management of a child with myxedema coma.Case presentation: This is a case of a 7-year-old female, diagnosed with congenital hypothyroidism at 5 months of age, but eventually was lost to follow-up. She came back after 7 years presenting with difficulty of breathing. She was seen hypothermic, obtunded, and in severe respiratory distress. She was severely stunted and underweight with coarse facial features. Initial laboratory work-up showed elevated Thyroid Stimulating Hormone (TSH) as well as decreased tri-iodothyronine (FT3) and thyroxine (FT4). She was immediately started on levothyroxine, with noted resolution of the edema and improvement in sensorium. There was also noted improvement in the patient’s ventilation and was sent home on Continuous Positive Airway Pressure (CPAP) while asleep.Conclusion: This case highlights the importance of having a high index of suspicion of its clinical manifestations, which could lead to earlier intervention thereby preventing further complications. A multidimensional approach is essential in managing this case, as various organ systems are involved in this condition.
Clinical and Epidemiological Profile of Reversible Acute Kidney Injury with Full Recovery: Experience of a Nephrology Department
Published on: 10th October, 2023
Purpose: Acute kidney injury (AKI) is a real public health problem due to its severity and gravity. In a 2013 meta-analysis, Susantitaphong, et al. estimated the incidence of AKI worldwide at between 10% and 20%. In the latter study, no African studies were included, given the lack of data in the literature. Our objective was to identify the clinical and paraclinical epidemiological characteristics of patients with AKI.Patients and methods: We conducted a retrospective study including patients who had AKI with recovery of normal renal function hospitalized in a nephrology service between 2002 and 2015.Results: Our population consisted of 107 men and 107 women with a median age of 61 years (IQR 43-73.25) of which 42.1% were multitargeted. Functional AKI represented the predominant mechanism of AKI retained in our study with a rate of 53.2% with dehydration as the main etiology for 108 patients (50.46%). Organic cause was retained in 38.8% of patients, with acute tubular necrosis (ATN) as the most frequent etiology (37.35%). Kidney disease improving global outcomes (KDIGO) stage 3 was the stage retained for 115 patients included in our series, 31 of whom required extra renal purification. During their hospitalization, 78.5% of the patients presented a persistent AKI (duration of the episode > 7 days). A glomerular filtration rate (GFR) lower than 60 ml/min/1.73 m² at discharge was found in 119 patients and 10 patients had a GFR higher than 90 ml/min/1.73 m². After 3 months from discharge, 77.5% of patients had a GFR between 60 and 90 ml/min/1.73 m².Conclusion: Our results give us an idea of the epidemiological and clinical characteristics of patients who have had acute renal failure with recovery of normal renal function and enable us to better recognize patients at risk in order to avoid such complications. AKI remains a major issue and knowing its epidemiological and clinical characteristics will allow its prevention.
Evolving Paradigms in Strep Throat: From Epidemiology to Advanced Therapeutics - A Comprehensive Overview
Published on: 29th December, 2022
Strep throat, a common affliction known for its hallmark symptom of a severe and sudden sore throat, is caused by the bacterium Streptococcus pyogenes, classified under Group-A Streptococcus (GAS) [1]. This condition not only impacts millions globally but also carries the risk of severe complications if left untreated [2]. Understanding strep throat goes beyond recognizing its symptoms; it entails an appreciation of its transmission dynamics, potential complications, and the evolving landscape of treatment and prevention strategies [3].
