Fine needle aspiration of thyroid (FNA) is broadly used as the preferred preoperatory test to evaluate thyroid nodules. The clinical importance of this procedure is primarily related the need to exclude Thyroid Cancer. There are few studies investigating the association between FNA and final pathology in patients with thyroid nodules with surgical indications. There is no evidence from studies in the southern area of Puerto Rico that investigate this association. This was a randomized cross-sectional study, 82 medical records were evaluated...

The Centers for Disease Control and Prevention (CDC) estimate that nearly 500,000 surgical site infections (SSIs) occur annually.[3] SSIs remain a substantial cause of morbidity and mortality among hospitalized patients. For this reason, we developed a quality assessment study with a perioperative antibiotic protocol that included antibiotic type, weight dependent dose, and intraoperative re-dosing regime for the proper administration of prophylaxis antibiotics prior to orthopedic surgery. We restricted our study to knee replacement and hip replacement surgeries...

Isolated ACTH deficiency (IAD) is a rare entity characterized by secondary adrenal insufficiency with low levels of serum cortisol, decreased production of ACTH, adequate secretion of other pituitary hormones and normal pituitary structure on radioimaging. The prevalence of IAD as a cause of secondary adrenal insufficiency has not been determined. Impairment of growth hormone (GH) secretion has been noted in 20 to 30% of patients with IAD which is normalized after glucocorticoid replacement. We report the case of a 50 years-old female with symptoms and laboratory results suggestive of adrenal insufficiency...

OBJECTIVES: The incidence and prevalence of Chronic Kidney Disease (CKD) patients treated with dialysis has continued to increase worldwide. These patients are at the highest risk of developing cardiovascular complications which contribute to their demise. The objective of this study was to describe the clinical and demographic characteristics of the patients on maintenance hemodialysis at the University Hospital, in San Juan Puerto Rico. METHODS: We reviewed a total of 55 active patients...

BACKGROUND: Autism Spectrum Disorder (ASD) is characterized by impaired social interaction and communication, and by restricted and repetitive behavior, that begins usually before a child is three years old.(1) Researchers have shown that prevalence rates in the U.S. may be as high as 1 in 68.(52) A number of studies have examined the effects of early exposure to anesthesia on brain development and subsequent impairment in neurocognitive function; yet, little is known about the possible effects of anesthetic agents on social-behavioral functioning...

Cerebrospinal fluid leaks of the cranial vault, constitute one of the most common complications after neurosurgical procedures. In this paper we introduce to you an observational study, in which a series of patients with this complication where managed by using elastic compression hat during 18 hours per day, for two weeks to four months. Every one of them presented complete resolution of the leak, without any recurrence until actual controls. After that we perform a review of the literature, demonstrating this is a new therapeutic management, being us the first group on reporting it...

Psoriasis is an immune disorder characterized by chronic activation of systemic inflammation. Morbidity and mortality in patients with psoriasis is attributed mainly to cardiovascular disease. There are studies in Caucasians and African- Americans, but little is known about how psoriasis is associated to coronary artery disease (CAD) in Hispanics. We intend to describe the angiographic findings of a group of Puerto Rican patients with psoriasis. Retrospective cohort study of 46 patients with psoriasis were studied...

Emergency physicians are many times the first-line practitioners to encounter circulatory emergencies. Amongst these many diseases we face, of importance are acute myocardial infarction, ischemic cerebrovascular accidents and pulmonary embolism. Familiarity with fibrinolytic agents and regimens, as well as indications and contraindications, are crucial to the emergency department physician. Fibrinolytic therapy has been shown to be beneficial and can serve as a bridge to definite treatment, while lowering the risk of morbidity and mortality...

Autoimmune hepatitis (AIH) may present with clinical, laboratory abnormalities and histological features suggestive of primary biliary cirrhosis (PBC) or primary sclerosing cholangitis (PSC). These variants of AIH are known as overlap syndromes. We present a case of a 62 year-old-male who presented with altered liver function tests, anemia and unintentional weight loss. Initial laboratories revealed anemia and a cholestatic pattern. Diagnostic work-up was remarkable for a positive antinuclear antibodies (ANA) test and a liver biopsy suggestive of an AIH-PBC overlap syndrome...

Eighty year old male patient with heart failure preserved ejection fraction (EF), Obstructive sleep apnea, peripherovascular disease admitted with increasing shortness of breath and found with pulmonary emboli. Baseline 2D-echocardiogram performed demonstrated preserved ejection fraction and a right thrombus in transit. Anticoagulation with weight based-low molecular weight heparin was given for six days. Follow-up echo performed demonstrated complete dissolution of right heart thrombi. Since there was complete dissolution of thrombi seen on right atrium, anticoagulation with Rivaroxaban was given instead...

BACKGROUND: Background: Gender disparities in pediatric fracture events has been well-documented however, less is known about racial disparities. The aim of this study is to investigate the epidemiology of pediatric bone fractures in a Hispanic population. METHODS: This is a retrospective cross-sectional analysis of patient’s records from a Pediatric Orthopeadic outpatient clinic in the Southwest region of Puerto Rico during a 1-year span (August 2014 – August 2015)...

Chest pain is a common complaint in the emergency department (ED). Besides a careful history and physical exam; electrocardiogram, laboratory tests and imaging studies are widely available diagnostic tests that are used for patient assessment. When ST elevation and elevated cardiac enzymes are present the most likely diagnosis are ST elevation myocardial infarction (STEMI) or myocarditis. In this case report we present two low risk patients for major adverse cardiac event with ST elevation and elevated cardiac enzymes and how a careful risk assessment and detailed electrocardiogram evaluation could help differentiating between these two diagnoses...

Eighty year old male patient with heart failure preserved ejection fraction (EF), Obstructive sleep apnea, peripherovascular disease admitted with increasing shortness of breath and found with pulmonary emboli. Baseline 2D-echo-cardiogram performed demonstrated preserved ejection fraction and a right thrombus in transit. Anticoagulation with weight based-low molecular weight heparin was given for six days. Follow-up echo performed demonstrated complete dissolution of right heart thrombi. Since there was complete dis- solution of thrombi seen on right atrium, anticoagulation with Rivaroxaban was given instead...

Since the introduction of liver transplant as treatment for end-stage liver disease, thousands of lives have been saved. To prevent organ rejection, immunosuppression is given chronically and hence, patients are at increased risk for opportunistic infections related to immunosuppression, especially within the first year after the transplant. However, opportunistic infections can occur years after the transplantation. Disseminated nocardiosis is one of these infections, and although the common presentation includes involvement of skin, lungs, and central nervous system...

FPrecursor T- or B-cell non-Hodgkin lymphoblastic lymphomas represent only a small fraction of pediatric cancer cases. Due to its rarity, the diagnosis of lymphoblastic lymphoma (LBL) in a pediatric patient is challenging, particularly if its manifestation is solely cutaneous. We describe the case of an infant with primary cutaneous B-cell LBL who was initially diagnosed by a primary care physician with an infectious etiology and consequently treated with topical and oral antibiotics. Subcutaneous nodules located on the head or neck of infants should raise suspicion for lymphoma and biopsy should be performed in order to rule out malignancy...

Hypothyroidism is the most common thyroid disorder in the adult population. Studies have found a higher prevalence of overt hypothyroidism in type 2 diabetic population than in the general population, but the relationship between subclinical hypothyroidism and diabetes mellitus 2 is still controversial. The aim of this study is to estimate the prevalence rate of hypothyroidism in the adult population receiving services in an ambulatory clinic and to determine if there is an association between hypothyroidism and diabetes mellitus...

We report clinical and molecular mechanisms relating the process of inflammation involved in the progression of obesity and the metabolic syndrome, emphasizing the cardiovascular problems developed in Hispanic populations. Namely, the incidence, component characteristics and complications of obesity and metabolic syndrome in island Puerto Ricans are described and evidence is presented supporting the fact that the metabolic syndrome may be milder in Puerto Rico than in the mainland United States because it is characterized by less aggressive coronary artery disease and a relatively normal lipid profile...

Jarcho-Levin syndrome (JLS) is a rare axial skeletal growth disorder characterized by the presence of multi-level costovertebral malformations, a short neck, a short trunk, and kyphoscoliosis at birth. Neural tube defects appear to be common findings in patients with JLS, and chest hypoplasia frequently leads to respiratory insufficiency and death in early childhood. There have been no previous studies in the literature on the anesthetic management of JLS with neural tube defects and hydrocephalus. Therefore, we have reported a case of JLS in a female full-term newborn, who underwent surgery for myelomeningocele repair and ventriculoperitoneal shunting, with the associated anesthetic challenges and their management...
