Toxoplasmic Chorioretinitis: About a Case in an Immunocompetent Adult at the Renaissance University Hospital Centre (UHC) in N’Djamena (Chad) and Review of the Literature

Toxoplasmic chorioretinitis also known as ocular toxoplasmosis is a parasitic infection caused by the obligately intracellular multiplying protozoan called Toxoplasma gondii. Active toxoplasmic chorioretinitis is a rare condition in immunocompetent people. We report a case of a 47-year-old patient who received reduced right visual acuity, left hemiparesis and eye pain. Examination of the right anterior segment of the eye is unremarkable. In the fundus of the right eye, there was a focus of active toxoplasmic chorioretinitis located in the macula at 1.5 mm papillary diameter next to old scar lesions. The ophthalmological examination of the left eye was unremarkable. The paraclinical assessment carried out on the patient shows a positive Remington test on two occasions three weeks apart. The clinical outcome after initiation of treatment was favorable with a healing of the active site within four weeks.

Ethnobotanical Study of Medicinal Plants Used for Treating Urinary Tract Infections in N’Djamena (Chad)

Introduction: Infection disease is a real publique health problem. The rise of resistance for modern antibiotic in infections treatment imposed us order alternatives. The study objective was to contribute in the knowledge of medicinal plants uses in urinary infections treatment in N’Djamena (Chad) in view for amelioration the traditional medicine in future. Methodology: The study was conducted in the city of N’Djamena in the Republic of Chad that interviewed 60 traditherapists on using 11 plants for urinary tract infections treatment. The methodology of this study consisted of the knowledge of medicinal plants that used by traditherapists, and the plants identification was done in the laboratory of IRED at Farcha. Results: A total of 60 traditherapists was interrogated on the plants used in the treatment of urinary tract infections among the population of N’Djamena. The majority of traditherapists interrogated in this study were male with the rate of 61.67% against female with the rate of 38.33%. The age range of traditherapists was between 20 to 80 years, 25 (41.67%) from the age range between 30 - 50 years and 35 (58.33%) in age range from 50 to 70 years. For the origin of their knowledge, the study showed that 72% of traditherapists inherited the knowledge from their family, while 15% inherited from the family and from training. The ethnic groups of the traditherapists were Sara (16%), Maraba (12%) and Massa (11%). According to the results, 18.33% were illiterates, 49% attended primary school and 33.34% the secondary school. Our study found that 11 species of plants belonging to 11 families were used in the treatment of urinary tract infection and the Ziziphus spina-christi was the most represented. According to traditherapists the Ziziphus spina-christi, Cassia obovata and Euphorbia hirta were the most frequent plants used in the urinary tract infections treatment. The parts of plants used in the treatment were leaves and bark, grained leaves and entire plants with the proportion of 50%, 16.67 and 15% respectively. Conclusion: This study revealed that the medicinal plants are variously used in the treatment of infection urinary tract in the city of N’Djamena.

Sydenham’s Chorea: Apropos of Three Observed Cases at the N’Djamena Mother and Child University Teaching Hospital (CHU-ME)-Chad

Introduction: Post-streptococcal chorea is the most common form of acquired chorea in children. Objective: The objective of this study was to contribute to better management of this condition by giving the characteristics of the epidemiological, clinical, biological, etiological, therapeutic and evolutionary aspects. Methodology: This was a retrospective and descriptive study from January 2021 to December 2021 which took place in the pediatrics department of the Mother and Child University Teaching Hospital of N’Djamena (CHU-ME). All the children in whom we observed abnormal involuntary movements whose age was less than or equal to 15 years were concerned. Result: there were three female children. The average age was 7.5, of which the two are 7 years old and the third is 8 years old. Two had a history of angina. A notion of polyarthralgia and dental caries was found in the third. The diagnosis of post-streptococcal chorea was retained on the basis of clinical arguments: observation of abnormal movements of the limbs and the face, which are involuntary, sudden with an insidious and progressive onset, muscular hypotonia, and psychic disorder. Medical imaging, in particular echocardiography, which objectified two cases of associated rheumatic valvular disease. Remission was observed in all three children after two weeks of treatment with haloperidol, penicillin. Those with associated rheumatic valve disease also received corticosteroid therapy. Complete remission of chorea was observed in all three girls. Prophylaxis in two patients based on Penicillin V was instituted. Conclusion: Although less frequent, post-streptococcal chorea is still seen in our country and is still an important health problem that needs more real medical efforts.

Seroprevalence of Chlamydia trachomatis Infection in Women of Procreate Age in the Mayo-Boneye Department in Chad

The objective of this study is to identify Chlamydia trachomatis to improve the health of women in the Department of Mayo-Boneye. Methodology: This is a prospective observational study that took place from October to December 2021, including 168 patients with their sociodemographic characteristics. The venous blood of the patients was collected in dry tubes and centrifuged to obtain the serum. The Chlamydia IgG Rapid Test Cassette was used for the detection of antibodies to Chlamydia infection. The Epi Info 7TM software was used to perform the statistical analyses. Results: A total of 168 patients were included in this study. The average age was 26.36 ± 9.21 years, the median was 25.5 years with the extremes of 14 years and 70 years. Among these patients, 46.43% were illiterate, 5.95% and 20.83% were primary and secondary school students, respectively, and 26.79% university students. For marital status, 66.67% were single, 16.67% married, 10.71% divorced and 5.95% widowed. Regarding the profession, 26.79% were traders, 8.93% were employees and 64.29% unemployed. In this study, the 168 patients had performed Chlamydia trachomatis serology among whom 02 (1.19%) were excluded for invalid results and 10.71% presented positive cases. The city of Bongor was the most infected with 61% of cases. Among these patients, 54.22% were linked to risk factors for Chlamydia trachomatis. The most infected age group was between 25 and 35 with a seroprevalence of 5.36% of cases. Conclusion: In this study, Chlamydia trachomatis was positive for 10.71% of diagnosed cases. The most affected age groups are young, sexually active women. The State should emphasize the screening of women, the awareness of students and academics.

Prevalence, Management and Outcomes of Enterocutaneous Fistulas in Buea Regional Hospital and Laquintinie Hospital of Douala. A Five Years Retrospective Study

Background: An Enterocutaneous fistula (ECF) is an abnormal connection between the intestinal tracts or stomach and the skin. They are a major catastrophe to the patient and surgeons and still have a high incidence of morbidity and mortality which varies between 6% - 33%;their management remains a big challenge. These patients frequently face complications, and a well-organized multidisciplinary approach must be implemented in their management to improve outcomes. Objectives: Our study aims to assess the prevalence, management and outcomes of enterocutaneous fistulas in Buea regional hospital and Laquintinie hospital of Douala over the past 5 years. Methods: This was a hospital-based retrospective study in Buea regional hospital and Laquintinie hospital of Douala. Records of patients who had enterocutaneous fistulas within the period of 1st January 2017 to 31st December 2020 in the surgical departments. Data included demographics, pre-operative diagnosis, comorbidities, type of fistula, management modality and means, the indication of operative treatment, length of stay in the hospital and outcomes. Data was analysed using SPSSv26. Results: The study constituted 1343 medical records of which 83 medical records of patients with enterocutaneous fistulas, giving a prevalence of 6.2%, female predominance at 59% (n = 49), 42.2% (n = 35) were referred cases from the periphery for better management. A vast majority (96.4%) occurred as post-operative complications with appendectomy the most common indication (18.8%). High output fistulas were predominant (43.4%). 59% (n = 47) were managed medically, 6% (n = 5) received both conservative and surgical modalities while 35% (n = 5) were managed surgically. 64.1% (n = 50) were placed on enteral nutrition while 35.9% (n = 28) were placed on parenteral nutrition. Peritonitis/infection 50% (n = 18) was the commonest indication of surgical treatment, followed by failure of medical treatment 25% (n = 9) then high output fistulas 16.7% (n = 6). Resection with end-to-end anastomosis was the preferred repaired work at 61% (n = 22). The mortality rate was 38.5% (n = 32), 29% (n = 24) healed after conservative treatment, 21.7% (n = 18) healed after surgery, 7.2% (n = 6) persisted after surgery while 3.6% (n = 3) persisted after conservative treatment. Anaemia, sepsis, electrolyte imbalance, dehydration and malnutrition were the commonest complications. Conclusion: The prevalence of enterocutaneous fistulas was high, with a female predominance and a mean age of 38 years. Most cases were seen as a referral from the periphery for better management. The greatest majority of fistulas occurred as a postoperative complications. Conservative management with enteral feedings was preferred, they had better outcomes and gave more chances of healing. The commonest indication of surgical treatment was an infection. Resection with end-to-end anastomosis was the preferred repaired work. The mortality rate was high, and anaemia, sepsis and electrolyte imbalance were the commonest complications.

Prevalence, Aetiology, and Clinical Profile of Acute Abdomen in Pregnancy in Southwest Cameroon: A 5-Year Retrospective Study

Background: Acute abdomen is one of the commonest reasons for presentation at the emergency department. The physiologic changes of pregnancy increase the chances of developing acute abdomen. The global incidence of acute abdomen in pregnancy range from 1 in 500 to 1 in 635 pregnant women. In 2018, a study in Azerbaijan reported a prevalence of 25%. However, to the best of our knowledge, very few studies have been carried out on this subject in Cameroon. Objectives: To determine the prevalence, assess the aetiologies, and review clinical profile of acute abdomen in pregnancy in the Southwest Cameroon. Methods: We conducted a 5-year retrospective study at the Obst/Gyn and Surgical units of Kumba, Buea, and Limbe Regional Hospitals. We included all files of pregnant women that were admitted for acute abdomen within the study period (1st Jan 2017 to 31st Dec 2021). Data was collected using a structured checklist adapted from previous studies. Descriptive statistics and statistical testing was done using SPSS version 25.0. Chi-square was used to compare categorical variables. p Results: Over 14,106 pregnant women were admitted to the aforementioned hospitals within the study period. 335 (2.4%) met our inclusion criteria. The patients’ age ranged from 17 to 43 years. The mean age was 27 years. Acute abdomen was more frequent (65%) in the first trimester. Ectopic pregnancy was the commonest obstetric aetiology while appendicitis was the commonest non obstetric surgical aetiology. Abdominal pain and tenderness were the most common presentation. Conclusion: The prevalence of acute abdomen in pregnancy in the Southwest Cameroon is 10 times higher than the global prevalence. Our study also confirmed the numerous aetiologies and varied clinical presentations of acute abdomen in pregnancy. Hence a wake-up call for primary care physicians.

Delay for Performing Laparotomy for Extra Uterine Pregnancy in N’Djamena Mother and Child University Hospital

Background: Ectopic pregnancy is defined as any pregnancy developed outside the uterine cavity. Objective: to study the relationship between the duration of laparotomy for EP and maternal prognosis. Patients and method. This was a prospective analytical study performed during a period of six (06) months, from May 1st to October 30, 2023, on delay time to perform laparotomy for EP in N’Djamena Mother and child University hospital (NMCUH). We included in this series all patients admitted for EP managed by laparotomy. Data were collected using Word software and analyzed using SPSS 18.0 version 2018. The p value statistical test was used to compare variables (p significant if ≤5%). Results: We recorded 92 cases of EP out of 5751 pregnancies, giving a frequency of 1.6%. Among patients diagnosed with EP, 76/92 (82.6%) had an indication of laparotomy. In 90.8%, the EP was ruptured. On admission, the diagnosis of EP was made within 1 hour in 15.8% of cases. The time to sign the consent allowing doctor to operate was >1 hour in 14.5% of cases. The operating room was unavailable in 34.2% of cases, with an unavailability of >1 hour in 17.1% of cases. Total salpingectomy was performed in 93.4%. Salpingotomy was performed in 6.6%. The lethality rate was 3.9% with significant value when the delay after indication and admission in the operating room is >1 (p value = 0.03). Conclusion: Various factors, such as the search for blood products, the time loss to sign the consent form and the unavailability of the operating room, delay the laparotomy, influence maternal prognosis. Anticipation on these factors is necessary in order to limit the proportion of delays.

Tuberculosis in the Carcinal Environment in Chad Due to the Mycobacterium Tuberculosis Circulante Complex

Tuberculosis (TB) is a serious infectious disease and its control is considered a challenge, particularly among vulnerable populations such as prisoners. The prevalence of TB in prisons is an alarming public health problem in many countries. The aim of this study is to describe the epidemiology of tuberculosis and the strategies for controlling this disease in the Chadian prison population. During the course of our study, the prevalence of tuberculosis in prisons was 9.64%. The age group between 55 years and over (43.33%) was the most represented in this study, and all patients were men with a frequency of 62.66%. The cross-tabulation of Culture_7H9G and Culture_7H9P showed that out of our total positive sample, we found a total of 87 positive strains and 63 negative strains. Our study shows that it is essential to know the prevalence of tuberculosis in all the country’s prisons. Indeed, this can serve as an indication of the need for action in prisons to reduce TB rates, in particular by improving the structure of prison environments, diagnosing new cases quickly and accurately, identifying drug-resistant strains and implementing effective, direct treatment observed in people with tuberculosis.

Clinical Case: Place of Cardiac Stimulation in Asymptomatic Significant Chronic Aortic Insufficiency Associated with Sinus Dysfunction

The association between aortic insufficiency and sinus dysfunction is rare. We reported a case of significant chronic degenerative aortic insufficiency associated with sinus dysfunction. This was a 66-year-old patient on follow-up for asymptomatic chronic aortic insufficiency who was referred to us for a preoperative invasive hemodynamic assessment. The indication for surgery was based on the left ventricular dilation criteria. The echocardiography and cardiac catheterization showed a disappearance between the aortic insufficiency and the left ventricular repercussion. Upon discovery of the sinus bradycardia, the patient received a single chamber pacemaker set at a base rate of 70 seconds in AAIR at first and then the patient was measured remotely. At five months, cardiac pacing resulted in a significant reduction in the left ventricular diameter and volume on the echocardiography and magnetic resonance imaging;therefore surgery was postponed.

Comparison of Gamma Pass Rate between the Dose-to-Water and Dose-to-Medium Reporting Modes for Patient-Specific QA Using a Helical Diode Array Dosimeter with a Fixed Phantom Density

Introduction: To compare the measured dose distributions to calculated ones in dose-to-water (Dw) and dose-to-medium (Dm) reporting modes for simple plans and patient-specific intensity modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) plans using ArcCHECK with a fixed phantom density. Methods: The recommended density value of 1.18 g/cm3 for Acuros XB and X-ray voxel Monte Carlo was assigned to ArcCHECK on CT images. A total of 45 simple plans, including a 1-field plan, a 3-field plan, a 4-field plan, a half-arc plan from 270° to 90°, and a full-arc plan, were assessed. Subsequently, the patient-specific 96 IMRT and VMAT plans were evaluated. Gamma analysis with a 3% normalized global dose error and a 3 mm distance-to-agreement criteria (γ3%G/3mm) was performed in the Dw and Dm. The change in γ3%G/3mm between Dw and Dm were statistically analyzed using JMPPro11 software. Results: The median values of γ3%G/3mm for all simple plans for Dw and Dm were 98.1% (range, 75.2% - 100%) and 95.5% (range, 23.7% - 100%), respectively (p 0.01). In the patient-specific IMRT and VMAT plans, the median values of γ3%G/3mm for Dw and Dm were 98.6% (range, 90.1% - 100%) and 90.5% (range, 38.5% - 97.2%), respectively (p 0.01). Conclusion: Our results showed that the calculated and measured dose distributions were in good agreement for Dw, but were not for Dm. From the viewpoint of the rationale of dosimetry, Dw shows better agreement with measured dose distribution when using the fixedphantom density recommended by the vendor.

Factors Influencing Behavior of Taking Medicine in Elderly Patients Undergoing Hemodialysis

Purpose: The elderly are often faced with multiple diseases, in particular hemodialysis (HD) which requires many kinds of medication. This study examined the factors influencing the behavior of taking medicine in elderly patients undergoing HD. Subjects and Methods: The subjects comprised 70 outpatients > 65 years undergoing HD (48 male and 22 female). The mean age of the patients was 72.5 ± 4.4 years. The mean duration of dialysis history was 6.1 ± 5.2 years. We performed a questionnaire survey using Medication Assessment Tool, The Kidney Disease Quality of Life (QOL)-Short Form and Acceptance for Dialysis Instrument. Result: Two factors related to poor behavior of taking medicine: dialysis history < 2 years and poor acceptance of dialysis. The multiple regression analysis showed patient satisfaction (β = –0.329, p < 0.01) and symptoms/problems (β = –0.273, p<0.05) as significant independent variables relating to behavior of taking medicine. Conclusion: Poor behavior of taking medicine is related to a short dialysis period, poor acceptance and poor satisfaction of dialysis therapy in elderly patients.

Maternal and Fetal Prognosis of Evacuated Parturients in N’Djamena Mother and Child Hospital (Chad)

Introduction: All pregnant women are at risk of obstetric complications leading to high fetal-maternal mortality and morbidity. The aim of this work was to evaluate the maternal and fetal prognosis of evacuated parturients. Patient and Method: we conducted a prospective analytical survey for four months, from April 1st to July 31st, 2018 in the Maternity of N’Djamena Mother and Child Hospital about the maternal and fetal prognosis of evacuated parturients. Any parturient evacuated or referred for obstetric complications was included. Study parameters were epidemiological, clinical, para-clinical, therapeutic and prognosis order. These parameters were analyzed in the SPSS 18 French version software. Results: Evacuated parturients represented 20% of maternity admissions. The average age was 23.9 years, with extremes ranging from 15 and 43 years. They were uneducated in 72.9%, primiparous in 46.8% of cases. The three delays were dominated by the 1st delay, which represented 34.1% of cases. In this series, 26.3% parturients had presented obstetric complications. Preruptive syndrome was the most common complication with 29.3% cases. Predisposing factors to maternal-fetal complications were low attendance antenatal care, late evacuation and distance travelled. The maternal mortality rate was 3%. Fetal complications were observed in 28.3% of cases and the neonatal mortality rate was 24.6%. Conclusion: The maternal and fetal complications of evacuated parturients are a real public health problem in our regions. The suppression of delays, capacity reinforcement of peripheral maternity and the periodic recycling peripheral centers to recognize obstetric emergencies will contribute to improve the maternal and fetal prognosis of evacuated parturients.

The Management Problem of Miliary Tuberculosis in the Service of Pneumo-Phtisiology at the National References University Teaching Hospital of N’Djamena (Chad): About 103 Cases

Introduction: Miliary tuberculosis (MT) is a rare form of tuberculosis (TB) and it is a major public health problem in our countries with limited resources. Materials and Methods: It is a retrospective and descriptive study that started from 1st January 2018 to 31 December 2020 at the pneumo-phtisiology service of the CHU-RN of N’Djamena., All records of patients aged at least 15 years treated for miliary tuberculosis confirmed by X-ray chest were included in our study. Results: The prevalence of TD was 1.5% (n = 103) of all TB diagnosed in the service. The sex ratio was 1.34. The average age was 37.7 years with extremes ranging from 19 to 80 years. A low social economic level was found in 75.7%. The principal comorbidity found in this study was HIV with the prevalence of (22.3%). The general signs were dominated by deterioration of general condition (96.1%) and fever (91.3%). The main symptoms were cough (85.4%) and dyspnea (52.4%). The radiology of chest found a homogeneous dissemination and symmetrical in both lung fields in 100% of cases. Our study reported that 14 (13.6%) of death cases were found among patients. Conclusion: TM is a severe form of TB;it affects a young population in our context. Mortality remains high with prevalence of 13.6% of cases. Early management would improve the prognosis.

100 Cases of Clinical and Etiological Aspects of Cardiac Insufficiency in N’Djamena, Chad

Introduction: Cardiac Insufficiency is progressively taking over as the leading cause of morbidity and mortality in the world and a major public health problem in Chad. Our study was to contribute and provide a deeper understanding of the clinical and etiological aspects concerning the etiology and management of Cardiac Insufficiency in N’Djamena, Chad. Due to having no published data to distinctly understand this pathology in this part of the world, we represent here a summary of available data which could be used to describe the clinical and etiological aspects of Cardiac Insufficiency and to help in changing practices for an optimal management as a baseline for comparison in future studies. Patients and Methods: This was a prospective, descriptive study conducted from November 30th 2011 to May 30th 2013 at the Good Samaritan Hospital of N’Djamena. Results: 100 hospitalized patients were included consecutively. The sex ratio was 1.08 with an average age of 40.21 ± 21.30 years. The main cardiovascular risk factors were high blood pressure (15%), obesity (12%) and diabetes (11%). Clinically, exertional dyspnea was found in 95% of cases, and signs of congestive heart failure in 61% of cases. The etiologies were 50% of Rheumatic valvulopathy, 22% of Dilated cardiomyopathy, 13% of Hypertensive cardiomyopathy and 12% of Congenital heart disease. Conclusion: The most common etiologies were Rheumatic valvulopathy, Congenital heart disease, Dilated cardiomyopathy and Hypertensive cardiomyopathy.

Management of Secondary Leyll Syndrome Due to Anti-Covid Vaccine in a Case, at the Renaissance University Teaching Hospital, Ndjamena (CHAD)

Introduction: Lyell’s syndrome (SL), called Toxic Epidermal Necrolysis is one of the most serious forms of medication accidents. It is an acute, rare pathology, its incidence is estimated at 1 to 2 cases out of one million inhabitants per year and its evolution can be fatal. Materials and Methods: We report the observation of a 60-year-old patient, with no significant pathological history, admitted to our intensive care unit at the Renaissance University Teaching Hospital in N’Djamena for the treatment of Toxic Epidermal Necrolysis. In whom the onset of symptoms dates back to few hours after vaccination against COVID-19 with Ag Johnson and Johnson. Results: An ophthalmology opinion was requested and the patient was put on Fucithalmic. In our case, in addition to the advanced age of the patient (60 years old), her SCORTEN was ≥5. Conclusion: The late management as well as the absence of a specific department for severe burns, which condition the presence of a technical plate was fatal to her despite multidisciplinary care: Resuscitators, Traumato-Orthopedist and ophthalmologist.

Giant Cell Tumor of the Wrist: Rare Location of the Distal Ulna

Giant cell tumor of the wrist is a rare, benign and usually symptomatic condition. The discovery is sometimes made following a medical imaging examination or a painful symptomatology or more often a visible or palpable swelling with or without vascular and/or nerve compression. At an advanced stage, the X-ray is of paramount importance. The well codified complete surgical resection is part of the therapeutic arsenal. We present a clinical case report of a young woman with a giant cell tumor localized in the wrist in N’Djamena, Chad. This case concerns a 25-year-old patient who presented in July 2020 of a painful swelling lateral to her left wrist bone and whose X-ray radiography showed lysis of the cortical bone in the lower third of the ulna. After the operative resection of the tumor mass, the pathological examination of the operative specimen revealed the diagnosis of a giant cell tumor. A giant cell tumor is a benign condition, with a few symptoms and the location at the ulna is exceptional. Complete surgical resection is a viable treatment option.

Aspects of Urolithiasis in Chadian Children: About of 191 Cases Collected at the Mother and Child University Hospital of N’Djamena (Chad)

Introduction: Urolithiasis in children is not sufficiently documented in Chad. Objectives: The aim of this work was to report the epidemiological, clinical and therapeutic aspects of urolithiasis in children in our environment. Patients and methods: This was a descriptive retrospective study of patients aged 0 - 15 years treated for urolithiasis between January 2015 and July 2020. The variables studied were age, gender, clinical, paraclinical and therapeutic aspects. Results: Among the 191 children, there were 164 boys (85.9%) and 19 girls (9.9%). The sex ratio was 8.63. The average age was 5.86 years with extremes (1 and 15 years). The symptomatology was dominated by dysuria. The ASP-ultrasound pair allowed the diagnosis in 183 cases (95.8%). The site of the calculus was bladder in 128 cases (67%). The average calculation size was 2.81mm. A supporting cause was found in only 1 case (posterior urethral valve). Treatment was surgical and dominated by cystolithotomy. The postoperative course was marked by 5 cases of parietal infections (2.6%) and 3 cases of vesico-cutaneous fistulas (1.6%). No case of death has been reported. Conclusion: Lithiasis is more common in boys in the lower urinary tract. Open surgery remains the only one practiced. Etiological research must be carried out to develop prevention strategies.

The Relation among the Solar Activity, the Total Ozone, QBO, NAO, and ENSO by Wavelet-Based Multifractal Analysis

There is an increasing interest in the relation between the solar activity and climate change. As for the solar activity, a fractal property of the sunspot number was studied by many works. In general, a fractal property was observed in the time series of dynamics of complex systems. The purposes of this study are to investigate the relations among the solar activity, total ozone, Quasi-Biennial Oscillation (QBO), the North Atlantic Oscillation (NAO), and El Ni?o-Southern Oscillation (ENSO) from a view of multi-fractality. To detect the changes of multifractality, we examined the multifractal analysis on the time series of the solar 10.7-cm radio flux (F10.7 flux), total ozone, QBO, NAO, and Ni?o3.4 indices. During the period 1950 and 2010, for the F10.7 flux and QBO index, the matching in monofractality or multifractality is observed and the increase and decrease of multifractality is similar;that is the change of multifractality is similar. In the same way, it is very similar, during the period 1985 and 2010, for the QBO and the total ozone, and during the period 1950 and 2010, for the QBO, and NAO and for the QBO, and Ni?o3.4. Compared to Ni?o3.4, the multifractality of NAO and QBO was strong and it turns out that they are undergoing unstable change. The relation among the solar activity, total ozone, QBO, NAO, and ENSO was clarified by the methods of fractal analysis and the wavelet coherence. These findings will contribute to the research of the relation between the solar activity and climate change.

Obstetric Complications Due to Female Genital Mutilation (FGM) at N’Djamena Mother and Child Hospital (Chad)

Background: Female genital mutilation (FGM) or female circumcision is all procedures involving partial or total removal of the external female genital organ or other injuries to the female genital organ whether for cultural or any other non-therapeutic reasons. Female genital mutilation causes numerous complications. Four in such cases multiplies obstetric complications. The aim of this study was to identify obstetric complications due to FGM. Patients and Material: We conducted a comparative prospective case-control study for three months, from January 1st to March 31st, 2014 in the maternity of N’Djamena Mother and Child. It focused on identifying neonatal and/or maternal complications during childbirth due to FGM. The study population consisted of pregnant women at term admitted for delivery labor. All parturients had to present the same sociodemographic and clinical profiles. A history of FGM was the main distinguishing criterion. Results: During the study period, we recorded 312 births to women with genital mutilation, among 1905 deliveries, representing a prevalence of 16.4%. One hundred ninety-one cases of circumcised women responding to the inclusion criteria were selected. Most of these women were between the ages of 20 and 29. The extreme age group was 15 and 39 (with a mean of 24.5 years). FGM was significant in age group over 20 years (Khi2 = 10.8;OR = 2.6 [1.4 - 4.9];P = 0.001). The type II of FGM which removed a part of the clitoris and the adjacent labia minora represented 64.40% patients in the group of women with FGM. Perinea laceration was the frequent maternal complication among parturient with FGM (Khi2 = 9.8;OR = 2.2 [1.4 to 3.6];P = 0.0007). FGM type III was associated with a high proportion of maternal complication (Khi2 = 11.2;OR = 7.3 [1.97 - 31.6];P = 0.0001). Still births were significantly higher in the group of parturient with FGM (11.5%, P = 0.015). Conclusion: Female genital mutilation is a common cultural practice in our country;it contributes to worsening maternal and fetal complications.
