The Duration-Based Measurement of Unemployment: Estimation Issues and an Application to Male-Female Unemployment Differences in France

This paper examines how unemployment can be measured in normative fashion - taking into account the mean and inequality of spell lengths - and how the extent of unemployment can be estimated from cross section data of the type found in labour force surveys. The issue is not straightforward since in these surveys completed durations of unemployed individuals are not observed yet they constitute the basis for calculating the kind of index that has been proposed to measure the extent of unemployment in a way that goes beyond the unemployment rate. The index proposed by Shorrocks has robust normative foundations and has an equivalent representation in terms of average complete duration and the density of completed durations. Building upon earlier work applied in the United States for estimating the first of these, we present a method that enables the index to be calculated based on an estimate of the density of completed durations. The approach is illustrated in the context of comparing male-female unemployment differences in France, where historically female unemployment has been higher than that of males

Hepatocellular carcinoma associated with pregnancy about 2 cases at the gynecological and obstetrical clinic of the Aristide Le Dantec hospital, Dakar, Senegal

The objective of our study was to report 2 cases of hepatocellular carcinomas associated with pregnancy followed in our structure and to review the literature. Our patients were 30 and 37-year-old multi-gesture females with chronic unattended viral hepatitis B in whom the diagnosis of hepatocellular carcinoma was made in the third trimester of pregnancy at 31 weeks of amenorrhea and 4 days and at 32 weeks of amenorrhea after the incidental finding of tumor hepatomegaly on abdominal-pelvic ultrasound. The main clinical signs were jaundice and hepatomegaly and paraclinical signs were dominated by hepatic cytolysis and anemia in addition to ultrasound images. Follow-up of pregnancies revealed no particularities. A caesarean section was scheduled at 32 weeks of amenorrhea and 32 weeks of amenorrhea and 3 days allowing the birth of two preterm newborns weighing 1210 and 1500 gm with Apgar scores of 8-10/10 and 7-9/10 respectively at the fifth minute. The immediate post-operative follow-up was simple. However, the maternal-fetal prognosis was poor with the death of both patients in a multi-visceral failure table occurring respectively at 6 weeks and 3 weeks after caesarean section. The newborns had died 8 days after birth. Although rare, these two cases challenge any obstetrician to think about liver cancer in pregnant women, especially those with chronic hepatitis B. Ultrasound examination of the liver, or even better, the MRI, which is more efficient, in order to suspect early on a possible liver cancer. Indeed, early diagnosis and a thorough medical approach are essential for the treatment of HCC in pregnant patients

Management of Renal Cell Carcinoma—Current Practice in Sub-Saharan Africa

There is a global variation in the incidence of renal masses with the developed nations having a greater incidence. About 80–90% of renal malignancies are renal cell carcinomas (RCC) which account for 2–4% of all cancers. In Africa and the Middle East, the age-standardized incidence for RCC is 1.8–4.8/100,000 for males and 1.2–2.2/100,000 for females. The management of renal cell cancer is challenging. A multidisciplinary approach is effective for diagnosis, staging, and treatment. Guidelines recommend active surveillance, thermal ablation, partial nephrectomy, radical nephrectomy, cytoreductive nephrectomy and immunotherapy as various modalities for various stages of RCC. However, open radical nephrectomy is most widely adopted as an option for treatment at various stages of the disease in sub-Saharan Africa due to its cost-effectiveness, applicability at various stages, and the reduced cost of follow-up. Nevertheless, most patients in the region present with the disease in the advanced stage and despite surgery the prognosis is poor

The measurement of unemployment using completed durations: evidence on the gender gap in unemployment in France

Is Schistosomiasis a Risk Factor for Bladder Cancer? Evidence-Based Facts

Background. Globally, approximately 20% of malignancy are caused by infection. Schistosoma infection is a major cause of bladder in most part of Africa. In 2018 alone, there were approximately 549,393 new cases and 199,922 deaths from bladder cancer. The presence of Schistosoma ova in the venous plexus of the bladder induces a cascade of inflammation causing significant tissue damage and granulomatous changes. Methodology. A literature review was conducted from 1995 to 2019 using PubMed, Google Scholar, African Journal Online, and Google databases. Relevant data on the association of “Schistosomiasis and Bladder cancer” in sub-Saharan Africa (SSA) were retrieved. Evidence Synthesis. Results from research using animal models to establish the carcinogenesis of Schistosoma and bladder cancer have been helpful but inconclusive. Immunoregulatory cytokines and genetic marker have been identified to play a role in the pathogenesis. In some parts of sub-Saharan Africa, there has been close association of squamous cell carcinoma and histological evidence of Schistosoma ova. Conclusion. There are some data to support the association between schistosomiasis and bladder cancer in sub-Saharan Africa. However, these have been limited by their design and may not sufficiently establish carcinogenesis. There is a need for more genomic and molecular research to better characterize S. haematobium and its effects on the bladder. Such goal will contribute immensely to Schistosoma bladder cancer prevention and control

Epidemiological and Diagnostic Aspects of Bladder Bilharziomas in the Urology Department of Idrissa Pouye General Hospital (HOGIP)

Objective. The aim of our study is to assess the diagnostic aspects of bladder bilharzioma in the Urology Department of Idrissa Pouye General Hospital (Senegal). Materials and Methods. It is a descriptive study from January 2013 to December 2018. The patients included in the study were those who had anatomopathological examination of bladder biopsy that showed a schistosomiasis pseudotumor of the bladder. The variables studied were sociodemographic, clinical symptoms, imaging findings, histology, and treatment. The data have been saved and analyzed by the 2013 Excel software. Results. Thirteen patients were included in our study. The average age was 27 ± 12.1 years. Sex ratio was 1.6. The majority of the patients were from the northern part of Senegal. Hematuria was the main symptom for all the patients. Cystoscopy was performed for all the patients and showed 5 granulomas and 8 fibrocalcic polyps. A transurethral resection of the bladder was performed, and treatment with praziquantel (40 mg/kg of bodyweight) has been carried out. One patient presented precancerous lesions such as metaplasia and dysplasia of the bladder mucosa. After a median follow-up of 40 months (6–57 months), ten patients had a favorable clinical and endoscopic outcome. Conclusion. Granulomas and fibrocalcic polyps of the bladder mucosa are, respectively, confused with squamous cell carcinoma and bladder lithiasis in endemic areas of schistosomiasis. Good cystoscopy interpretation can provide the diagnosis of bladder bilharzioma and start the treatment
