Myocardial bridging (MB) is a congenital anomaly where a coronary artery branch or group of branches extends inside a tunnel consisting of myocardium. Although it is mostly considered “benign,” it is reported that MB may lead to significant cardiac problems and sudden cardiac deaths. While it is a congenital anomaly, its symptoms usually arise at further ages rather than childhood. The literature on MB in children is in the form of case reports or small case series. This is why pediatric cases are assessed in the light of information obtained from adults. This review compiled the literature on MB in adults and children and compared it, as well as discussing questions arising regarding the clinic, diagnosis, and treatment of MB.

Solitary fibrous tumors of the spine are rare lesions. Their description in the literature is limited to case reports and small case series. While generally benign lesions, they can recur and occasionally occur as malignancies. Here the authors present the case of a 10-year-old boy, the youngest patient and first preadolescent reported thus far, with this condition. In addition, they perform a comprehensive review of all previously published cases of spinal solitary fibrous tumors.

Category: Ankle, Basic Sciences/Biologics Introduction/Purpose: Subchondroplasty® (SCP®) (Zimmer Holdings, Inc, Warsaw, IN) is a relatively new procedure that was developed in 2007 for the treatment of bone-marrow lesions (BMLs). It involves the injection of flowable nanocrystalline calcium phosphate (CaP) synthetic bone substitute into the BML using fluoroscopic-guidance, in order to promote healing and reinforce the effected region. Although a newer technique, SCP has been shown promising results in the knee through several different small case-series. The foot and ankle literature is sparser, with only a few documented case-reports or case-series. As a result, we wanted to report our small case-series of patients who underwent talar SCP and went on to develop avascular necrosis (AVN). Methods: A retrospective review was conducted of patients who underwent SCP for a talar BML at our facility or were referred to our facility after undergoing SCP at an outside institution. Patients who developed iatrogenic talar AVN postoperatively were included in the study. Patient characteristics, comorbidities, imaging, and need for further surgery was analyzed. Results: Four patients were identified who had previously undergone talar SCP and went on to develop iatrogenic talar AVN. Two patients had their original SCP performed at our facility, whereas the other two patients were referred from outside institutions. All four patients were symptomatic from their AVN. Two patients have undergone revision surgical intervention, while the other two patients are pending surgical intervention. Conclusion: This case-series is the first study, to our knowledge, to report iatrogenic talar AVN after undergoing SCP for talar BMLs. Although early studies in the Foot and Ankle literature are promising for use of this technology, these studies have been small and surgeons should be aware of this potential complication.

Diabetic neuroarthropathy of the knee or Charcot knee (CK) is a lesser-known complication of diabetes mellitus, with a limited number of case reports and small case series published in the literature. The majority of these reports describe the complexities and challenges that arise in these patients undergoing knee arthroplasty procedures. We present two cases of CK, including a rare case of concurrent bilateral disease, and also a review of the current literature.

The term granuloma annulare (GA) appropriately describes the classic type characterized by ringed erythematous plaques with histological palisaded granulomatous inflammation. However, GA now includes a range of disease. Over time, more atypical, rare types have been reported in isolated case reports or small case series. Here, we describe a unique case of generalized GA presented by two morphologically different lesions in a 52 years old diabetic man. To the best of our knowledge, this association has never been reported in the literature.

Background: To investigate the hypothesis that cases of arteritis similar to thromboangiitis obliterans (TAO) and associated with the use of cannabis were caused by cannabis or THC (dronabinol), or that cannabis use is a co-factor of TAO. Patients and methods: A systematic review on case reports and the literature on so-called cannabis arteritis, TAO, and cardiovascular effects of cannabinoids was conducted. Results: Fifteen reports with 57 cases of an arteritis associated with the use of cannabis and two additional case series of TAO, in which some patients also used cannabis, were identified. Clinical and pathological features of cannabis-associated arteritis do not differ from TAO and the major risk factor of TAO, tobacco use, was present in most, if not in all of these cases. The proposed pathophysiological mechanisms for the development of an arteritis by cannabis use are not substantiated. Conclusions: The hypothesis of cannabis being a causative factor or co-factor of TAO or an arteritis similar to TAO is not supported by the available evidence. The use of the term “cannabis arteritis” should be avoided until or unless more convincing scientific support is forthcoming.

SummaryHematopoietic colony-stimulating factors (CSFs) are largely used in patients with cancer undergoing cytotoxic treatment to accelerate neutrophil recovery and decrease the incidence of febrile neutropenia. Clinical practice guidelines for their use have been recently established (1), taking into account clinical benefit, but also cost and toxicity. Vascular occlusions have been recently reported among the severe reactions associated with the use of CSFs, in anedoctal case reports (2, 3), consecutive case series (4) and randomized clinical trial (5, 6). However, the role of CSFs in the pathogenesis of thrombotic complications is difficult to ascertain, because pertinent data are scanty and widely distributed over a number of heterogenous investigations. We report here a systematic review of relevant articles, with the aims to estimate the prevalence of thrombosis associated with the use of CSFs and to assess if this rate is significantly higher than that observed in cancer patients not receiving CSFs.

Abstract Introduction Herpetic whitlows in infants are rare. Previous authors only reported individual case reports. We present a case series of six infants. Materials and Methods This is a retrospective study of six cases of herpetic whitlows in infants seen by the senior author (MMA) over the past 23 years (1995–2017 inclusive). The following data were collected: age, sex, digit involved in the hand, mode of transmission, time of presentation to the author, clinical appearance, presence of secondary bacterial infection, presence of other lesions outside the hand, method of diagnosis, treatment, and outcome. Results All six infants initially presented with classic multiple vesicles of the digital pulp. In all cases, there was a history of active herpes labialis in the mother. Incision and drainage or deroofing of the vesicles (for diagnostic purposes) resulted in secondary bacterial infection. Conclusion The current report is the first series in the literature on herpetic whitlows in infants. We stress on the mode of transmission (from the mother) and establishing the diagnosis clinically. In these cases, no need for obtaining viral cultures or polymerase chain reaction; and no medications are required. Once the vesicles are disrupted, secondary bacterial infection is frequent and a combination of oral acyclovir and intravenous antibiotics will be required.

Background: Zika virus infection during pregnancy has been recently associated with congenital microcephaly and other severe neural tube defects. However, the magnitude of confirmed cases and the scope of these anomalies have not been extensively documented. This review focuses on the magnitude of laboratory-confirmed congenital Zika virus cases among probable cases and describing the patterns of congenital anomalies allegedly caused by the Zika virus, information which will inform further research in this area. Methods: We conducted a literature search for English-language articles about congenital Zika virus infection using online electronic databases (PubMed/MEDLINE, POPLINE, Embase, Google Scholar, and Web of Knowledge). The search terms used were, “zika”, “pregnancy”, [year], “microcephaly”, “infants”, “children”, “neonates”, “foetuses”, “neural tube defect”, and “CNS manifestations” in different combinations. All articles reporting cases or case series between January 2015 and December 2016 were included. Data were entered into a Microsoft Excel database and analysed to obtain proportions of the confirmed cases and patterns of anomalies. Results: A total of 24 articles (11 case series, 9 case reports, and 4 others) were found to be eligible and included in this review. These articles reported 919 cases, with or without microcephaly, presumed to have congenital Zika virus infection. Of these cases, 884 (96.2%) had microcephaly. Of the 884 cases of microcephaly, 783 (88.6%) were tested for Zika virus infection, and 216 (27.6%; 95% confidence interval, 24.5% to 30.8%) were confirmed to be Zika virus-positive. In addition to microcephaly, other common abnormalities reported – out of 442 cases investigated – were calcifications of brain tissue (n=240, 54.3%), ventriculomegaly (n=93, 20.8%), cerebellar hypoplasia (n=52, 11.7%), and ocular manifestations (n=46, 10.4%). Conclusion: Based on the available literature, Zika virus infection during pregnancy might lead to a wide array of outcomes other than microcephaly. There is a need for more epidemiological studies in Zika-endemic areas, particularly in Africa, to ascertain the role of Zika virus in causing congenital neurological defects.
