BackgroundInfection in health workers (HWs) has characterized outbreaks of Ebola virus disease (EVD) and Marburg virus disease (MVD). We conducted a systematic review to investigate infection and mortality rates and common exposure risks in HWs in EVD and MVD outbreaks.MethodsWe searched the EMBASE and PubMed databases to identify articles posted before 27 December 2017, with no language restrictions. Data on the number, frequency, and mortality of HW infection and exposure risks were extracted.ResultsNinety-four articles related to 22 outbreaks were included. HW infections composed 2%–100% of cases in EVD and 5%–50% of cases in MVD outbreaks. Among exposed HWs, 0.6%–92% developed EVD, and 1%–10% developed MVD. HW infection rates were consistent through outbreaks. The most common exposure risk situations were inadequate personal protective equipment and exposure to patients with unrecognized EVD/MVD. Similar risks were reported in past EVD/MVD outbreaks and in the recent outbreak in West Africa.ConclusionsMany outbreaks reported high proportions of infected HWs. Similar HW infection rates and exposure risk factors in both past and recent EVD and MVD outbreaks emphasize the need to improve the implementation of appropriate infection control measures consistently across all healthcare settings.

Fibrohistiocytic tumors of the skin comprise a large range of lesions. One such tumor is the atypical fibroxanthoma (AFX), which is widely considered as a "pseudomalignant" tumor. It is derived from fibroblasts and expresses a variety of histiocytic markers. We present a case of AFX, localized in the right temporal region of the scalp, successfully treated with surgical excision. Immunohistochemical staining helps differentiate this tumor from others in the clinical differential diagnosis, including malignant melanoma, squamous cell carcinoma, and other nonmelanocytic spindle cell tumors such as leiomyosarcoma, rhabdomyosarcoma, angiosarcoma, liposarcoma, and dermatofibrosarcoma protuberans. Historically, AFX was believed to be a superficial variant of malignant fibrous histiocytoma (MFH). However, MFH is now considered a more generalized term for a sarcomatous neoplasm of the subcutaneous tissue. The histopathology of MFH shares features with some malignant mesenchymal neoplasms such as liposarcoma, leiomyosarcoma, rhabdomyosarcoma, and angiosarcoma, but can be differentiated using immunohistochemistry and/or electron microscopy. More recently, the examples of MFH that do not exhibit a more specific line of differentiation have been reclassified as undifferentiated pleomorphic sarcoma (UPS). Many authors currently cannot draw a distinction between AFX and UPS. The clinical and histopathological differences between AFX and UPS are often difficult to delineate. It is probable that they represent two poles of the same disease. Surgical excision in the patient we describe resulted in excellent aesthetic results with lack of recurrence in the 7-month postoperative period.

The occupational hazards of health workers (HWs) in standard work environments have been well defined in both the developed and developing world during routine working conditions. Less defined are the hazards to HWs during pandemics, epidemics, natural disasters, wars, conflicts, and other crises. How do crises affect the infrastructure of medical systems? What are the distinct needs of the patient population during crises? What are the peculiarities of the Crisis Health Worker (CHW)? What are the known CHWs’ occupational risks? What are the protective factors? By means of a PubMed search, we synthesized the most relevant publications to try to answer these questions. Failures of healthcare infrastructure and institutions include CHW shortages, insufficient medical supplies, medications, transportation, poorly paid health workers, security concerns, and the absence of firm guidance in health policy. Healthcare needs affecting the patient population and CHWs include crisis-induced injury and illness, hazardous exposures, communicable diseases, mental healthcare, and continuity of care for pre-crisis medical conditions. CHWs’ occupational hazards include supply deficiencies, infectious disease transmission, long working hours, staff shortages, financial reimbursements, mental fatigue, physical exhaustion, and inconsistent access to clean water, electricity, and Internet. CHWs suffer from injuries and illnesses that range from immediate, debilitating injuries to chronic, unforeseen effects like mental fatigue, physical exhaustion, anxiety, burnout, and even post-traumatic stress syndrome (PTSD). Protective factors include personal traits such as adaptability and resilience as well as skills learned through structured education and training. Success will be achieved by constructively collaborating with local authorities, local health workers, national military, foreign military, and aid organizations.

Objective:The aim of this study is to examine the associations between lag times following occupational low back injury and the length of work disability.Methods:In a retrospective cohort study using workers’ compensation claims, random effects Tobit models were used to explore how disability length relates to three lag times: the number of days from the date of injury to reporting the injury, the number of days from the date of injury to medical care, and the number of days from the date of injury to initiating work disability.Results:In general, shorter lag times for each of the different lags were related to shorter lengths of disability.Conclusions:Decreasing the length of the lag times in reporting injuries, receiving medical care, and missing work may help to decrease the length of work disability for workers after low back injury.
