Chilaiditi’s sign refers to the interposition of the colon (usually the transverse colon) between the diaphragm and the liver. When associated with abdominal pain it is referred to as Chilaiditi’s syndrome. Chilaiditi’s sign is rare entity with an estimated incidence of 0.025 to 0.28% worldwide. The sign occurs more frequently in males, with a male to female ratio of 4:1. Apparent pneumoperitoneum seen on imaging below the right hemidiaphragm, a life-threatening condition, may in fact be merely Chilaiditi’s sign. Awareness of this phenomenon and its consideration as a differential diagnosis is essential to prevent unnecessary laparoscopic intervention.Here we present a case of a 74-year-old male who was incidentally found to have free air under the diaphragm without symptoms of abdominal pain. After further evaluation by the radiologists and surgeons it was concluded that he had Chilaiditi’s sign and no further intervention was required. However, due to the lack of awareness of this radiographic finding patients can be subjected to unnecessary surgical intervention.

Mucosal melanoma is a rare variant of melanoma representing around 1% of total cases of melanoma diagnosed. The usual sites of mucosal involvement are the sino-nasal passages, the oral cavity, and less commonly the upper gastrointestinal (GI) tract. It also has been reported to occur in vulvovaginal and anorectal mucosa. We present a rare case of mucosal melanoma that presented as recurrent epistaxis, headache, and sinus pressure. CT maxillofacial imaging revealed a large mass right nasal cavity. This was biopsied by ENT and shown to be mucosal melanoma. This was treated with palliative radiation followed by immunotherapy with nivolumab. Along with details of the case, we also discuss current treatment options with a focus on the role of immunotherapy and its efficacy in cases of head and neck mucosal melanoma. Our review of literature supports use of combination immunotherapy (including both nivolumab and ipilimumab) as it shows greater efficacy than either therapy alone. When combined with radiation therapy (RT) the overall response rate is improved and RT induces an abscopal effect; where benefits of RT are also seen at nonirradiated locations. In our patient, the use of radiation was essentially palliative as the patient was deemed to not be a surgical candidate. We discuss in our literature review the optimum timing of radiation in relation to definitive surgery or immunotherapy.

BackgroundMany health service delivery models are adapting health services to meet rising demand and evolving health burdens in low- and middle-income countries. While innovative private sector models provide potential benefits to health care delivery, the evidence base on the characteristics and impact of such approaches is limited. We have developed a performance measurement framework that provides credible (relevant aspects of performance), feasible (available data), and comparable (across different organizations) metrics that can be obtained for private health services organizations that operate in resource-constrained settings.MethodsWe synthesized existing frameworks to define credible measures. We then examined a purposive sample of 80 health organizations from the Center for Health Market Innovations (CHMI) database (healthmarketinnovations.org) to identify what the organizations reported about their programs (to determine feasibility of measurement) and what elements could be compared across the sample.ResultsThe resulting measurement framework includes fourteen subgroups within three categories of health status, health access, and operations/delivery.ConclusionsThe emphasis on credible, feasible, and comparable measures in the framework can assist funders, program managers, and researchers to support, manage, and evaluate the most promising strategies to improve access to effective health services. Although some of the criteria that the literature views as important – particularly population coverage, pro-poor targeting, and health outcomes – are less frequently reported, the overall comparison provides useful insights.

Background and Objectives: There is a limited evidentiary base on the development of family medicine in different contexts and countries. The lack of evidence impedes our ability to compare and characterize family medicine models and identify areas of success that have led to the effective provision of care. This paper offers a comparative compilation and analysis of the development of family medicine training programs in seven countries: Brazil, Canada, Ethiopia, Haiti, Indonesia, Kenya, and Mali. Methods: Using qualitative case studies, this paper examines the process of developing family medicine programs, including enabling strategies and barriers, and shared lessons. An appreciative inquiry framework and complex adaptive systems thinking inform our qualitative study. Results: Committed partnerships, the contribution of champions, health policy, and adaptability were identified as key enablers in all seven case studies. The case studies further reveal that some enablers were more salient in certain contexts as compared to others, and that it is the interaction of enablers that is crucial for understanding how and why initiatives succeeded. The barriers that emerged across the seven case studies include: (1) resistance from other medical specialties, (2) lack of resources and capabilities, (3) difficulty in sustaining support of champions, and (4) challenges in brokering effective partnerships. Conclusions: A key insight from this study is that the implementation of family medicine is nonlinear, dynamic, and complex. The findings of this comparative analysis offer insights and strategies that can inform the design and development of family medicine programs elsewhere.
