Panniculite au cours dâun traitement dâune dermatomyosite par du mĂ©thotrexate
La panniculite est une manifestation rare au cours des dermatomyosites (DM). Lâapparition dâune panniculite au cours dâun traitement par du mĂ©thotrexate (MTX) est exceptionnelle et nâa Ă©tĂ© dĂ©crite que dans 3 cas. Nous rapportons lâobservation dâune patiente ĂągĂ©e de 50 ans atteinte dâune DM diagnostiquĂ©e en 1997 et traitĂ©e par une corticothĂ©rapie avec une Ă©volution favorable aux plans clinique et biologique. A lâoccasion dâune rechute 2 ans plus tard, la corticothĂ©rapie a Ă©tĂ© majorĂ©e et du mĂ©thotrexate Ă une dose hebdomadaire de 7,5 mg a Ă©tĂ© rajoutĂ©. LâĂ©volution Ă©tait rapidement favorable. Dix huit mois plus tard, la patiente prĂ©sentait de multiples nodules sous cutanĂ©s siĂ©geant aux 4 membres et aux fesses, dont lâexamen anatomopthologique concluait Ă une panniculite. Il nâexistait aucun signe dâĂ©volutivitĂ© de la DM. La dose de prĂ©dnisone a Ă©tĂ© augmentĂ©e Ă 0,5 mg/kg/j toujours en association au MTX mais sans aucune amĂ©lioration. Le MTX a Ă©tĂ© arrĂȘtĂ© et les lĂ©sions cutanĂ©es ont complĂštement disparu en 2 mois sans aucune rĂ©cidive avec un recul actuel de 42 mois. Notre observation est particuliĂšre par la survenue dâune panniculite chez une patiente ayant une DM traitĂ©e par du MTX et illustre la difficultĂ© diagnostique. Cette entitĂ© doit ĂȘtre connue malgrĂ© son caractĂšre exceptionnel puisque lâarrĂȘt du MTX induit en gĂ©nĂ©ral la disparition des nodules sous cutanĂ©s.Pan African Medical Journal 2016; 2
Une colite à CMV révélant un lupus érythémateux systémique
Le cytomĂ©galovirus (CMV) est responsable dâinfections souvent asymptomatiques chez les immunocompĂ©tents mais Ă©galement dâinfections graves chez les immunodĂ©primĂ©s notamment chez les patients lupiques. La rĂ©activation du CMV au cours du lupus est une complication frĂ©quente mais rarement inaugurale. Nous rapportons lâobservation dâun patient ayant prĂ©sentĂ© une colite Ă CMV rĂ©vĂ©latrice dâun lupus Ă©rythĂ©mateux systĂ©mique. Le diagnostic a Ă©tĂ© retenu sur les donnĂ©es sĂ©rologiques, de la biopsie colique et la bonne Ă©volution aprĂšs un traitement par ganciclovir
Central retinal vein occlusion revealing celiac disease
Introduction: Thrombosis has been widely reported in coeliac disease (CD) but central retinal vein occlusion (CRVO) is rarely described.
Case presentation: A 27-year-old woman presented with acute visual loss and was diagnosed with CRVO. Her protein S and protein C levels were low and CD was diagnosed on the basis of endoscopic, immunological and histological results. A gluten-free diet resulted in favourable evolution.
Conclusion: CD should be considered in young patients with thrombosis, especially if in an unusual location. Treatment is based on a gluten-free diet

Measuring the availability of human resources for health and its relationship to universal health coverage for 204 countries and territories from 1990 to 2019: a systematic analysis for the Global Burden of Disease Study 2019
Background: Human resources for health (HRH) include a range of occupations that aim to promote or improve human health. The UN Sustainable Development Goals (SDGs) and the WHO Health Workforce 2030 strategy have drawn attention to the importance of HRH for achieving policy priorities such as universal health coverage (UHC). Although previous research has found substantial global disparities in HRH, the absence of comparable cross-national estimates of existing workforces has hindered efforts to quantify workforce requirements to meet health system goals. We aimed to use comparable and standardised data sources to estimate HRH densities globally, and to examine the relationship between a subset of HRH cadres and UHC effective coverage performance.
Methods: Through the International Labour Organization and Global Health Data Exchange databases, we identified 1404 country-years of data from labour force surveys and 69 country-years of census data, with detailed microdata on health-related employment. From the WHO National Health Workforce Accounts, we identified 2950 country-years of data. We mapped data from all occupational coding systems to the International Standard Classification of Occupations 1988 (ISCO-88), allowing for standardised estimation of densities for 16 categories of health workers across the full time series. Using data from 1990 to 2019 for 196 of 204 countries and territories, covering seven Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) super-regions and 21 regions, we applied spatiotemporal Gaussian process regression (ST-GPR) to model HRH densities from 1990 to 2019 for all countries and territories. We used stochastic frontier meta-regression to model the relationship between the UHC effective coverage index and densities for the four categories of health workers enumerated in SDG indicator 3.c.1 pertaining to HRH: physicians, nurses and midwives, dentistry personnel, and pharmaceutical personnel. We identified minimum workforce density thresholds required to meet a specified target of 80 out of 100 on the UHC effective coverage index, and quantified national shortages with respect to those minimum thresholds.
Findings: We estimated that, in 2019, the world had 104·0 million (95% uncertainty interval 83·5â128·0) health workers, including 12·8 million (9·7â16·6) physicians, 29·8 million (23·3â37·7) nurses and midwives, 4·6 million (3·6â6·0) dentistry personnel, and 5·2 million (4·0â6·7) pharmaceutical personnel. We calculated a global physician density of 16·7 (12·6â21·6) per 10â000 population, and a nurse and midwife density of 38·6 (30·1â48·8) per 10â000 population. We found the GBD super-regions of sub-Saharan Africa, south Asia, and north Africa and the Middle East had the lowest HRH densities. To reach 80 out of 100 on the UHC effective coverage index, we estimated that, per 10â000 population, at least 20·7 physicians, 70·6 nurses and midwives, 8·2 dentistry personnel, and 9·4 pharmaceutical personnel would be needed. In total, the 2019 national health workforces fell short of these minimum thresholds by 6·4 million physicians, 30·6 million nurses and midwives, 3·3 million dentistry personnel, and 2·9 million pharmaceutical personnel.
Interpretation: Considerable expansion of the world's health workforce is needed to achieve high levels of UHC effective coverage. The largest shortages are in low-income settings, highlighting the need for increased financing and coordination to train, employ, and retain human resources in the health sector. Actual HRH shortages might be larger than estimated because minimum thresholds for each cadre of health workers are benchmarked on health systems that most efficiently translate human resources into UHC attainment
The global burden of cancer attributable to risk factors, 2010-19 : a systematic analysis for the Global Burden of Disease Study 2019
Background Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally. Methods The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented. Findings Globally, in 2019, the risk factors included in this analysis accounted for 4.45 million (95% uncertainty interval 4.01-4.94) deaths and 105 million (95.0-116) DALYs for both sexes combined, representing 44.4% (41.3-48.4) of all cancer deaths and 42.0% (39.1-45.6) of all DALYs. There were 2.88 million (2.60-3.18) risk-attributable cancer deaths in males (50.6% [47.8-54.1] of all male cancer deaths) and 1.58 million (1.36-1.84) risk-attributable cancer deaths in females (36.3% [32.5-41.3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20.4% (12.6-28.4) and DALYs by 16.8% (8.8-25.0), with the greatest percentage increase in metabolic risks (34.7% [27.9-42.8] and 33.3% [25.8-42.0]). Interpretation The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.

Global burden of 288 causes of death and life expectancy decomposition in 204 countries and territories and 811 subnational locations, 1990â2021: a systematic analysis for the Global Burden of Disease Study 2021
BACKGROUND Regular, detailed reporting on population health by underlying cause of death is fundamental for public health decision making. Cause-specific estimates of mortality and the subsequent effects on life expectancy worldwide are valuable metrics to gauge progress in reducing mortality rates. These estimates are particularly important following large-scale mortality spikes, such as the COVID-19 pandemic. When systematically analysed, mortality rates and life expectancy allow comparisons of the consequences of causes of death globally and over time, providing a nuanced understanding of the effect of these causes on global populations. METHODS The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 cause-of-death analysis estimated mortality and years of life lost (YLLs) from 288 causes of death by age-sex-location-year in 204 countries and territories and 811 subnational locations for each year from 1990 until 2021. The analysis used 56â604 data sources, including data from vital registration and verbal autopsy as well as surveys, censuses, surveillance systems, and cancer registries, among others. As with previous GBD rounds, cause-specific death rates for most causes were estimated using the Cause of Death Ensemble model-a modelling tool developed for GBD to assess the out-of-sample predictive validity of different statistical models and covariate permutations and combine those results to produce cause-specific mortality estimates-with alternative strategies adapted to model causes with insufficient data, substantial changes in reporting over the study period, or unusual epidemiology. YLLs were computed as the product of the number of deaths for each cause-age-sex-location-year and the standard life expectancy at each age. As part of the modelling process, uncertainty intervals (UIs) were generated using the 2·5th and 97·5th percentiles from a 1000-draw distribution for each metric. We decomposed life expectancy by cause of death, location, and year to show cause-specific effects on life expectancy from 1990 to 2021. We also used the coefficient of variation and the fraction of population affected by 90% of deaths to highlight concentrations of mortality. Findings are reported in counts and age-standardised rates. Methodological improvements for cause-of-death estimates in GBD 2021 include the expansion of under-5-years age group to include four new age groups, enhanced methods to account for stochastic variation of sparse data, and the inclusion of COVID-19 and other pandemic-related mortality-which includes excess mortality associated with the pandemic, excluding COVID-19, lower respiratory infections, measles, malaria, and pertussis. For this analysis, 199 new country-years of vital registration cause-of-death data, 5 country-years of surveillance data, 21 country-years of verbal autopsy data, and 94 country-years of other data types were added to those used in previous GBD rounds. FINDINGS The leading causes of age-standardised deaths globally were the same in 2019 as they were in 1990; in descending order, these were, ischaemic heart disease, stroke, chronic obstructive pulmonary disease, and lower respiratory infections. In 2021, however, COVID-19 replaced stroke as the second-leading age-standardised cause of death, with 94·0 deaths (95% UI 89·2-100·0) per 100â000 population. The COVID-19 pandemic shifted the rankings of the leading five causes, lowering stroke to the third-leading and chronic obstructive pulmonary disease to the fourth-leading position. In 2021, the highest age-standardised death rates from COVID-19 occurred in sub-Saharan Africa (271·0 deaths [250·1-290·7] per 100â000 population) and Latin America and the Caribbean (195·4 deaths [182·1-211·4] per 100â000 population). The lowest age-standardised death rates from COVID-19 were in the high-income super-region (48·1 deaths [47·4-48·8] per 100â000 population) and southeast Asia, east Asia, and Oceania (23·2 deaths [16·3-37·2] per 100â000 population). Globally, life expectancy steadily improved between 1990 and 2019 for 18 of the 22 investigated causes. Decomposition of global and regional life expectancy showed the positive effect that reductions in deaths from enteric infections, lower respiratory infections, stroke, and neonatal deaths, among others have contributed to improved survival over the study period. However, a net reduction of 1·6 years occurred in global life expectancy between 2019 and 2021, primarily due to increased death rates from COVID-19 and other pandemic-related mortality. Life expectancy was highly variable between super-regions over the study period, with southeast Asia, east Asia, and Oceania gaining 8·3 years (6·7-9·9) overall, while having the smallest reduction in life expectancy due to COVID-19 (0·4 years). The largest reduction in life expectancy due to COVID-19 occurred in Latin America and the Caribbean (3·6 years). Additionally, 53 of the 288 causes of death were highly concentrated in locations with less than 50% of the global population as of 2021, and these causes of death became progressively more concentrated since 1990, when only 44 causes showed this pattern. The concentration phenomenon is discussed heuristically with respect to enteric and lower respiratory infections, malaria, HIV/AIDS, neonatal disorders, tuberculosis, and measles. INTERPRETATION Long-standing gains in life expectancy and reductions in many of the leading causes of death have been disrupted by the COVID-19 pandemic, the adverse effects of which were spread unevenly among populations. Despite the pandemic, there has been continued progress in combatting several notable causes of death, leading to improved global life expectancy over the study period. Each of the seven GBD super-regions showed an overall improvement from 1990 and 2021, obscuring the negative effect in the years of the pandemic. Additionally, our findings regarding regional variation in causes of death driving increases in life expectancy hold clear policy utility. Analyses of shifting mortality trends reveal that several causes, once widespread globally, are now increasingly concentrated geographically. These changes in mortality concentration, alongside further investigation of changing risks, interventions, and relevant policy, present an important opportunity to deepen our understanding of mortality-reduction strategies. Examining patterns in mortality concentration might reveal areas where successful public health interventions have been implemented. Translating these successes to locations where certain causes of death remain entrenched can inform policies that work to improve life expectancy for people everywhere.

Primary Sjögrenâs syndrome complicated by anti-neutrophil cytoplasmic antibody-mediated crescentic glomerulonephritis
Ocular and oral dryness are the hallmark of Sjögrenâs syndrome (SS). However, SS can be associated with a variety of complications, affecting organs such as the liver, kidneys, lungs, muscle, and nervous system. Renal involvement has been usually in the form of tubulointerstitial nephritis. However, glomerulonephritis is rare in primary SS. We report three clinical cases of SS with anti-neutrophil cytoplasmic antibody-mediated crescentic glomerulo-nephritis treated with prednisone and cyclophosphamide, with favorable outcome
Venous thromboembolism risk and prophylaxis in the acute hospital care setting-results of the Endorse study in Tunisia
BACKGROUND: There are not information about the risk of venous thromboembolism (VTE) and its prophylaxis in Tunisia. AIM: To report the Tunisian results of a multinational crosssectional study, designed to assess the prevalence of VTE risk in the acute hospital care setting and to determine the proportion of at risk patients who receive effective prophylaxis.
METHODS: All hospital inpatients aged 40 years or over admitted to a medical ward or these aged 18 years or over admitted to surgical ward, in 5 Tunisian hospitals were assessed for risk of VTE on the basis of hospital chart review. The 2004 American College of chest physicians (ACCP) evidence based consensus guidelines were used to assess VTE risk and to determine whether patients were received recommended prophylaxis.
RESULTS: 885 were enrolled, 212 (24%) were surgical and 673 (76%) were medical. 408 (44, 9%) judged to be at risk, 95 (44, 8%) are surgical and 313 (46, 5%) are medical. LWMH are the most used. Mechanical prophylaxis was never used.
CONCLUSION: The percentage of at risk patient in Tunisia is comparable to these of other countries. The majority of at risk patient are medical. The prophylaxis was under used. Hospital strategies to assess patient VTE risk and implementation of prophylaxis protocols are needed
