Introduction: Abstinence-only sexuality education (AOSE); is required in the public school systems of many states, raising public health concerns and perpetuating health disparities through school systems. This study aimed to determine the correlations between state-mandated AOSE and the rates of adolescent HIV and teen pregnancy.

Methods: Using publicly available data on all 50 United States' laws and policies on AOSE, states were ranked according to their level of abstinence emphasis on sexuality education (Level 0 - Level 3);. We calculated the relative proportion of Black students in public schools and the proportion of families below the federal poverty line then ranked them by state. We compared the states' ranks to the incidence of adolescent HIV and teen pregnancy in those states to identify associations between variables.

Results: The majority of states (~44 percent ); have legally mandated AOSE policies (Level 3); and adolescent HIV and teen pregnancy rates were highest in these Level 3 states. There were significant, positive correlations between HIV incidence rates of 13-19 year olds, HIV rates of 20-24 year olds, teen pregnancy rates, and AOSE level, with the proportion of the population that lives below the federal poverty level, and whether they attended schools that had a greater than 50 percent of an African American population.

Discussion: These data show a clear association between state sexuality education policies and adolescent HIV and teen pregnancy rates not previously demonstrated. Our data further show that states that have higher proportions of at-risk populations, with higher adolescent HIV and teen pregnancy rates, are more likely to also have restrictive AOSE policies. These populations may be more likely to attend public schools where AOSE is taught, increasing their risk for HIV and teen pregnancy. The World Health Organization considers fact-based Comprehensive Sexuality Education a human right, and the authors believe it is past time to end harmful, discriminatory sexuality education policies in US public schools.

Introduction: Pyomyositis has traditionally been considered a tropical disease. Increasing prevalence has been observed in more northern climates, especially with HIV, immunosuppression, and IV drug abuse as predisposing factors. Pyomyositis has the tendency to mimic other conditions, such as muscle contusion, necrotizing fasciitis, or septic arthritis. The rarity of this disease and non-specificity of its symptoms often lead to delay in appropriate diagnosis and treatment.

Case: 24-year-old man, seen 2 days prior in orthopedics clinic and the Emergency Department for persistent gluteal pain thought to be due to right-sided sciatica, was admitted following worsening pain, diffuse generalized weakness with polyarthralgias and myalgias These symptoms were associated with night sweats, shaking chills, and difficulty walking. Prior to onset of symptoms, the patient vacationed in Cayman Islands and experienced a stingray bite on his right hand as well as numerous cuts on rocks in stagnant waters. He was febrile with WBC count of 18.7 K/ μL and was found to have methicillin-sensitive Staphylococcus aureus (MSSA); bacteremia. Magnetic resonance imaging (MRI); of his lumbar spine on admission was unremarkable. Repeat MRI 4 days later showed extensive inflammation within musculature with multiple abscesses around right sciatic foramen and septic arthritis of the sacroiliac joint. The patient was subsequently diagnosed with MSSA septic polyarthritis and required several orthopedic procedures. Infectious and oncologic work up was unremarkable. Transesophageal echocardiogram showed 0.3 cm x 0.5 cm aortic valve vegetation, which was managed medically. Repeat MRI 11 days after initiation of appropriate antibiotics and surgeries showed improvement in muscular edema. Based on the MSSA susceptibilities, the patient was treated with 6 weeks of intravenous cefazolin and 2 weeks of oral cephalexin thereafter.

Discussion: Awareness of tropical pyomyositis in colder climates remains scarce, although cases have been reported in immunosuppressed patients. However, in healthy patients, accurate history of travel and trauma is important in evaluation for predisposing factors for pyomyositis. Early antibiotic and appropriate surgical interventions are imperative for management of this disease in order to prevent systemic toxicity, dissemination of infection, and long-term debility.

Background: Cerebral venosinus thrombosis (CVT); is an uncommon, potentially fatal disease that is more common in young adults and children. Thrombophilia, elevated estrogenic states, and infections are the most common risk factors in patients who develop CVT.

Case: A 69-year-old man with a right-sided odontogenic infection presented with fever, headache, opthalmoplegia, and periorbital swelling. Imaging revealed evidence of meningitis and thrombosis of bilateral ophthalmic veins, the cavernous sinus, right internal jugular vein, and sigmoid sinus. The patient was treated with empiric antibiotic therapy and unfractionated heparin. He recovered with only mild impairment in right eye abduction.

Discussion: Early diagnosis and prompt treatment of CVT is vital in reducing the associated morbidity and mortality. Unfractionated or low molecular weight heparin may be safely used in CVT patients. Thrombolytic therapy is an option in clinically severe cases. Treatment also includes addressing the underlying cause and management of early complications.

A family brought their 61-year-old mother to the emergency department because for 4 days she had been confused, incoherent, and somnolent. She also had dysphagia, dysarthria, diplopia, and had fallen out of bed. She had been in the hospital 3 weeks earlier for atrial fibrillation and an exacerbation of congestive heart failure. She also carried a diagnosis of chronic obstructive pulmonary disease and used an albuterol inhaler. She was obese (BMI of 45); and had adult-onset diabetes mellitus. She had a 43 pack-year history of cigarette smoking but had recently quit. Soon after arriving in the emergency department, she had an ECG (Figure);.

Case: A 48 year-old man with no past medical history was sent to our emergency department (ED); from a primary care clinic for hypertensive urgency of 200/130. The man reported an intermittent non-productive cough of approximately one year's duration and worsening dyspnea on exertion and orthopnea over the last month with lower extremity swelling. Of note, he emigrated from Honduras twenty years ago. Blood pressure normalized with administration of Lasix in the ED. Physical exam revealed rales in lung bases bilaterally, jugular venous distension, lower extremity pitting edema with serpiginous patches of erythema and excoriation, and a cardiac gallop. Labs showed peripheral eosinophilia, thrombocytopenia, elevated creatinine, hyperbilirubinemia, hyperglycemia, and mild transaminitis. Transthoracic echocardiogram revealed a dilated left ventricle with global hypokinesis and severely depressed systolic function with an ejection fraction less than 15 percent . The patient was diuresed, and subsequent left and right heart catheterizations were normal. CT chest showed a small nodule in the right upper lobe. Tests for Coccidiosis, Trypanosoma cruzi, and Mycobacterium tuberculosis were negative; however the acid fast bacilli culture grew Mycobacterium fortuitum. A Strongyloides stercoralis antibody test was positive, and the patient was treated with two doses of oral ivermectin with one dose of intravenous ceftriaxone, and discharged. Two months later, his eosinophilia resolved, but he remained symptomatic with productive cough and weight loss, and was started on an outpatient course of oral ciprofloxacin and trimethoprim-sulfamethozole for M. fortuitum.

Disscusion: Strongyloides-infected patients may carry the parasite for years without prominent symptoms. Endemic throughout South America, Strongyloides persists in its hosts through a lifecycle of autoinfection, which, over time, increases parasite burden and can lead to a hyperinfection syndrome whereby filiariform larvae penetrate organ tissue, most commonly: heart, central nervous system, lungs and liver. We suspect chronic eosinophilia and disseminated filiaria to be the etiology of the non-ischemic dilated cardiomyopathy in this patient. Standard treatment of strongyloidiasis is ivermectin, however, mortality owing to transient bacteremia in the setting of hyperinfection syndrome is high. Therefore, bacteremia prophylaxis with gram negative rod coverage should be considered before antiparasitic agent initiation.

Introduction: Inflammation and venous thrombosis enjoy a close Relationship. We present a patient who had multiple DVTs following the discontinuation of anti- TNF-α therapy.

Case: A 34 year old African American female with a history of multiple DVT's, miscarriages, and reported Crohn's disease presented with shortness of breath. In the Emergency Department, CTA showed bilateral pulmonary emboli. The patient had been off adalimumab for one year and reported abdominal pain with 6-7 non-bloody bowel movements daily. She had been prescribed lovenox for her unprovoked DVTs yet reported missing several doses prior to admission. Following admission, she developed severe abdominal pain prompting an emergent CT angiogram and she then developed a pulseless painful left lower extremity. CT revealed a partially occlusive thrombus in the infra-renal abdominal aorta, proximal left common iliac artery, and right renal artery with subsequent right renal infarction. Following emergent vascular surgery to restore blood flow to the left lower extremity, the patient received four days of plasma exchange and high dose steroids for potential catastrophic antiphospholipid syndrome. Serology for APLA was negative. The patient was discharged with lifelong anticoagulation.

Discussion: The endothelial surface is a complex organ that works in concert with the surrounding environment. Inflammation and thrombus formation is closely associated. TNF-α can increase the expression of adhesion molecules, specifically, tissue factor, on the surface endothelial cells and promote thrombosis. Suppression of TNF-α expression by low molecular weight heparin has been shown to inhibit the inflammatory cascade and reduce thrombus formation in animal models. Clinical data is less clear. Interruption of TNF blockers has been shown to increase the risk of DVT in patients with rheumatoid arthritis undergoing orthopedic surgery. For patients with Bechet's syndrome, anti-TNF agents appear help treat patients with pulmonary artery thrombosis. Further review of anti-TNF-α therapy in our general medicine patient population may disclose additional risks associated with discontinuation of these medications.

A 71 year-old female with a past medical history significant for hypertension, hyperlipidemia, diabetes, and strokes, presented initially to the stroke service with a sudden onset of right facial droop, right-sided weakness, dysarthria, and seizures that had gotten progressively worse for six weeks.

Background: Little data exist regarding the effects of prophylactic perioperative protocol on reducing surgical site infections. Based on national efforts to prevent SSIs and current evidence in the literature supporting the importance of perioperative prophylaxis, it would seem logical that expanding upon current perioperative protocol would help prevent SSIs.

Hypothesis: Multiple variables present risk factors in the development of SSIs in the perioperative period, and optimization of patient management during this time with a series of non-invasive and inexpensive protocols may help prevent SSIs.

Methods: A six-step perioperative protocol was developed and instituted in our community hospital performing mostly outpatient orthopaedic surgical procedures. The rates of SSIs, diagnosed clinically according to the Center of Disease Control SSI criteria by two orthopaedic surgeons performing the operations during postoperative visits, were recorded in all patients whose index procedure fell within a two-month period before and after the introduction of our protocol. Proportions of infections were compared using Pearson's x2 test.

Results: There were a total of 312 cases performed by two surgeons; evaluated two months before, 153, and two months after, 159, the implementation of our protocol. The incidence of SSIs before initiation of the protocol was 9.1% n=14; and after implementation, the incidence was zero 14 vs. 0, p less than 0.0001.

Conclusion: Multiple variables in the perioperative period can contribute to the incidence of SSIs and can be controlled with diligent attention to prophylactic measures such as those presented in this paper. Our new perioperative protocol represents a cost-effective, and noninvasive method to prevent SSIs in an orthopaedic practice.

Case report: A 54 year-old woman with diabetes mellitus type two and end-stage renal disease on hemodialysis presented to the emergency department with a four day history of generalized malaise, fever, and chills. Her symptoms were also associated with occasional dyspnea without a cough. She reported intermittent chronic diarrhea with hemodialysis which was currently unchanged. On the day of admission, she could not tolerate hemodialysis due to her symptoms. Over the past year she admitted to night sweats and a 40 pound weight loss. She denied having palpitations, chest pain, hemoptysis, lymph node swelling, sick contacts, or recent travel. The remainder of the review of systems was negative.

Coronary artery ectasia also known as dilated coronopathy is a relatively rare finding that is most commonly associated with atherosclerosis. Several alternative reasons including congenital malformations and chronic inflammation have been identified as a cause of CAE. In this case, we discuss a 61-year-old male with postoperative chest pain who was found to have localized CAE in the absence of significant atherosclerosis. We also elucidate the recently proposed markers of chronic inflammation that might be associated with coronary artery ectasia.
