Background: Angiosarcoma is a rare but aggressive malignancy with a high predilection for the head and neck. There have been few case reports of the development of angiosarcoma in a nonfunctional arteriovenous fistula in a hemodialysis patient. Methods: After institutional review board approval, a retrospective chart analysis is conducted to present the case of a patient who received plastic surgical treatment at our hospital. Results: We present the case of a 44-year-old male who presented with ischemic changes and paresthesias of the upper extremity associated with the development of angiosarcoma in an arteriovenous fistula. Conclusions: Angiosarcoma remains a rare but important diagnosis to include in the differential diagnosis for upper extremity pain and paresthesias in chronic renal failure and nonfunctioning arteriovenous fistula.

We report on our work with the street community of Pittsburgh, specifically, a community-based action initiative we call the Mobile Thriving Respite (Institutional Review Board approval was obtained from our university). For 5 years, student advocate ethnographers from Point Park University have gathered data (e.g., long- and short-term interviews, participant-observations generating fieldnotes). The data revealed and supported the need for thriving beyond surviving homelessness. The data endorsed the creation of the mobile thriving respite. In the first part of this work, we will discuss some critical concepts regarding homelessness as a phenomenon and then argue that while surviving as enduring is necessary, there are some for whom survival is a perpetual, lethal state of being. We will discuss the theoretical foundations to the respite and offer researchers’ ethnographic accounts of the respite’s process and progress (We had to temporarily end the respite during the Covid-19 pandemic. To date, the respite has returned with “pop up” events outside at various locations). We will outline how the mobile thriving respite is a praxis as site of resistance as well as an emergent strategy, and an instantiation of communitas. We will then revisit surviving as collectively bearing witness and testifying to the lived experiences of those living outside.

Changes of bone during pregnancy and during lactation evaluated by bone mineral density (BMD) may have implications for risk of osteoporosis and fractures. We studied BMD in women of differing ages, parity, and lactation histories immediately postpartum for BMD,T-scores, andZ-scores. Institutional Review Board approval was received. All women while still in hospital postpartum were asked to participate. BMD was performed by dual-energy X-ray absorptiometry (DXA) machine at femoral neck (FN) and lumbar spine (LS) by a single technician. Of 132 participants, 73 (55.3%) were ≤30 years; 27 (20.5%) were primiparous; 36 (27.3%) were grand multiparous; 35 (26.5%) never breast fed. Mean FNT-scores andZ-scores were higher than respective mean LS scores, but all means were within the normal limits. Mean LST-scores andZ-scores were highest in the grand multiparas. There were only 2 (1.5%) outliers with lowZ-scores. We conclude that, in a large cohort of Israeli women with BMD parameters assessed by DXA within two days postpartum, meanT-scores andZ-scores at both the LS and FN were within normal limits regardless of age (20–46 years), parity (1–13 viable births), and history of either no or prolonged months of lactation (up to 11.25 years).

Secondary Phenotypes

Kabuki Syndrome is rare and poorly documented, initially mentioned by Niikawa and Kuroki in 1981. The prevalence of the syndrome among live births is 1:32,000. Case reports are now available, which correlates to improved techniques for accurate diagnosis. This study focused on a systematic comparative review of the phenotypes of individuals with Kabuki Syndrome, with the purpose to facilitate diagnosis. The systematic review was done with a bibliographic survey of case studies using the following databases: Pubmed, Science Direct and Google Scholar, in conjunction with the following key-words: Kabuki syndrome, phenotype, KMT2D and case report. The literature shows that patients with this syndrome present five main characteristics, besides several types of secondary phenotypes. These characteristics present variations in permeability as well as expressivity of some genes in individuals, therefore, a characterization through phenotype alone becomes limited, making it necessary to perform genetic analysis for differential diagnosis. In order to increase the knowledge and elucidate mechanisms of Kabuki syndrome, we suggest further studies that utilize animal models.

Abstract Background Hamman’s sign is a rare phenomenon. Louis Hamman described this pathognomonic clicking chest noise in association with pneumomediastinum in 1937. This typical noise can also be present in left-sided pneumothorax. Clinical cases already mention this pericardial knock in 1918 in gunshot wounds of the left chest and in 1928 in cases of spontaneous left-sided pneumothorax. However, the sound itself has only rarely been recorded. Case summary We describe a case of a young man with no significant medical history who was referred to the hospital with chest pain and audible clicks, documented with his smartphone. Imaging studies including chest radiograph and computed tomography scan revealed a left-sided pneumothorax. The patient underwent semi-urgent insertion of a thorax drain. His clinical outcome was excellent. Discussion In recent years only a few case reports describe Hamman’s sign, as it is rare and happens only transiently. This case report includes the audible clicks recorded by the patient with his smartphone. We stress the importance of thoracic clicking sounds as key symptom in the differential diagnosis of left-sided pneumothorax, pneumomediastinum, and valvular pathology such as mitral valve prolapse.

Global Ratings

Abstract Background Single-item global ratings are commonly used at the end of undergraduate clerkships and residency rotations to measure specific competencies and/or to compare the performances of individuals against their peers. We hypothesized that an Internet-based instrument would be feasible to adequately distinguish high- and low-ability residents. Materials and Methods After receiving Institutional Review Board approval, we developed an Internet-based global ranking instrument to rank 42 third-year residents (21 in 2008 and 21 in 2009) in a major university teaching hospital's department of anesthesiology. Evaluators were anesthesia attendings and nonphysicians in 3 tertiary-referral hospitals. Evaluators were asked this ranking question: “When it comes to overall clinical ability, how does this individual compare to all their peers?” Results For 2008, 111 evaluators completed the ranking exercise; for 2009, 79 completed it. Residents were rank-ordered using the median of evaluator categorizations and the frequency of ratings per assigned relative performance quintile. Across evaluator groups and study years, the summary evaluation data consistently distinguished the top and bottom resident cohorts. Discussion An Internet-based instrument, using a single-item global ranking, demonstrated feasibility and can be used to differentiate top- and bottom-performing cohorts. Although ranking individuals yields norm-referenced measures of ability, successfully identifying poorly performing residents using online technologies is efficient and will be useful in developing and administering targeted evaluation and remediation programs.

True arterial aneurysms of the upper extremity are rare. The case described is that of a 48-year-old man presenting with median neuropathy and distal vascular compromise 4 years after ligation of a brachiocephalic arteriovenous fistula. We describe our approach and present a review of the relevant literature.
