RESUMEN
The acromioclavicular joint (ACJ) is commonly injured due to a force to the lateral aspect of the shoulder with the arm in adduction resulting in vertical or multidirectional instability. However, in this case report, we present a rare case of an athlete with isolated horizontal ACJ instability, which was treated surgically using a hamstring allograft. We highlight the surgical technique use to stabilize the joint in the horizontal (anterior to posterior) plane. Isolated horizontal instability of the ACJ is very rare and, to our knowledge, this surgical technique has not been reported in the case of a young athlete.
RESUMEN
Shoulder instability episodes are observed in high-energy injuries, such as seizures. In this case report, we highlight the management of a failed distal tibial allograft procedure for recurrent shoulder instability in a patient with a bony Bankart lesion and epilepsy. The patient was treated with an iliac crest autograft and a proximal humerus osteochondral allograft procedure. To our knowledge, the use of an iliac crest autograft for glenoid bone loss and a proximal humerus osteochondral allograft after several failed shoulder instability procedures in a patient with epilepsy has not been reported.
RESUMEN
Letters of Recommendation (LORs) are widely utilized for admission to both undergraduate and graduate programs, and are becoming even more important with the decreasing role that standardized tests play in the admissions process. However, LORs are highly subjective and thus can inject recommender bias into the process, leading to an inequitable evaluation of the candidates' competitiveness and competence. Our study utilizes natural language processing methods and manually determined ratings to investigate gender and cultural differences and biases in LORs written for STEM Master's program applicants. We generate features to measure important characteristics of the LORs and then compare these characteristics across groups based on recommender gender, applicant gender, and applicant country of origin. One set of features, which measure the underlying sentiment, tone, and emotions associated with each LOR, is automatically generated using IBM Watson's Natural Language Understanding (NLU) service. The second set of features is measured manually by our research team and quantifies the relevance, specificity, and positivity of each LOR. We identify and discuss features that exhibit statistically significant differences across gender and culture study groups. Our analysis is based on approximately 4000 applications for the MS in Data Science and MS in Computer Science programs at Fordham University. To our knowledge, no similar study has been performed on these graduate programs.

Complex regional pain syndrome (CRPS) is a potentially devastating condition that can result in severe psychological and social morbidity. It is a diagnosis of exclusion, and other pathologic entities must be ruled out first. Glomus tumors are exquisitely painful benign vascular tumors that are most common in the hand and are rarely found in the lower extremity. Here, we present a case of a patient who developed a focus of severe anterior knee pain and tenderness a few months after a car accident that had been misdiagnosed as CRPS for 15 years. She coincidentally developed a sarcoma of her ipsilateral leg distal to this site. Magnetic resonance imaging of the sarcoma included the area of knee pain where, interestingly, it identified a separate small soft-tissue mass. A glomus tumor was diagnosed histologically in a needle biopsy specimen from this mass, which was resected along with the sarcoma. For the first time in 15 years, despite the additional sarcoma surgery, she reported relief of her pain and complete resolution of her "CRPS."

Mycobacteriophage Faze9 is a novel lytic phage that was isolated from soil collected in Scranton, PA, using the host Mycobacterium smegmatis mc2155. Faze9 has a double-stranded DNA genome composed of 67,503 kbp, has a G+C content of 68.9%, encodes 91 predicted proteins, and is closely related to mycobacteriophages in the B2 subcluster. .
