A Gastric Duplication Cyst Initially Mimicking Staghorn Calculus.

Gastric duplication cyst is an uncommon anomaly typically found in the greater curvature of the stomach. It is usually diagnosed in children and quite difficult to diagnose in adult because of variable presentation. We present a 76-year woman who was admitted for abdominal pain of few weeks' duration. Her X-ray showed calcification in the region of left kidney, and she was subsequently managed with a presumptive diagnosis of staghorn calculus. Computerized Tomography (CT) scan of her abdomen disclosed calcification in the gastric wall for which an endoscopic ultrasound and biopsy was done. Findings were consistent with the presence of gastric epithelium and a diagnosis of gastric duplication cyst was made. Surgery was the continuation of care. The presence of symptomatic gastric cyst in an elderly patient is very rare. This is the first case in which gastric duplication cyst mimicked staghorn calculus on abdominal X-ray. Consequently, this diagnosis, though rare, should be considered in the differentials of upper abdominal pain.

Successful Trial of Octreotide and Ketorolac for the Management of Increased Biliary Drain Output: A Case Report.

We describe a 69-year-old male patient with the status of obstructive jaundice post percutaneous biliary drainage for prior obstructive jaundice and who presented with a complaint of generalized weakness and increased output from the drainage tube. The patient developed worsening jaundice, which was noted to be obstructive in nature with a marked dilatation of the biliary tree and a distal obstruction of the common bile duct. Subsequently, a percutaneous biliary drain was placed for symptomatic management. However, the patient continued to have increased output from the drain, approximating 3-4 liters a day, which made the patient dependent on continuous intravenous hydration. The case presented a therapeutic challenge in reducing the drainage amount. We have tried a successful approach based on the physiologic effect of octreotide and nonsteroidal anti-inflammatory drugs (NSAIDs) in the formation of bile secretion. This approach has not been clearly described in the literature. We highlight the importance of further study to validate the use of these medications in similar clinical scenarios.

Preventing Cushing: Iatrogenic Cushing Syndrome due to Ritonavir-Fluticasone Interaction.

Ritonavir is commonly used in low doses to boost plasma levels of protease inhibitors in patients with human immunodeficiency virus (HIV) infections. It is also a potent inhibitor of cytochrome P450. We present a 50-year-old African American male with past medical history of HIV on highly active antiretroviral therapy (HAART), which also included ritonavir and long standing asthma that has been treated with inhaled fluticasone, who presented with back pain. He had central obesity, prominent abdominal striae and wasted extremities on physical examination. Laboratory tests showed low morning serum cortisol and suboptimal cosyntropin test consistent with adrenal insufficiency. Computed tomography (CT) of the spine showed a fracture of inferior endplate of the lumbar (L3) vertebra. The cause of osteoporosis is believed to be iatrogenic Cushing syndrome caused by enhanced levels of inhaled fluticasone effects secondary to inhibition of cytochrome P450. The patient was managed surgically and fluticasone was discontinued.

A Rare Case of Pulmonary Mucosa-Associated Lymphoid Tissue Lymphoma Transforming into Diffuse Large B-Cell Lymphoma.

Mucosa-associated lymphoid tissue lymphoma (MALToma) is a low grade B-cell lymphoma that develops from the lungs, intestinal tract, salivary gland, and other organs and is included under extranodal marginal zone lymphoma. When a primary pulmonary MALToma develops from bronchus-associated lymphoid tissue (BALT), it is called BALT lymphoma (BALToma). The etiology of MALToma is not clear; however, an association between chronic inflammatory conditions and BALToma has been observed. Transformation of MALToma to high grade lymphoma is very rare. We experienced a case of MALToma that had developed from the lungs in a patient who was undergoing treatment for latent tuberculosis and rapidly transformed into high grade B-cell lymphoma.

An Invasive Case of Left-Sided Endocarditis Caused by Pseudomonas aeruginosa in a Patient with History of Intravenous Drug Abuse.

Infective endocarditis, caused by Pseudomonas aeruginosa, is rarely seen in clinical practice. It has been reported mainly in intravenous drug abusers (IVDA). We present a case of a 63-year-old male who presented with abdominal pain and fever. Computed tomography (CT) abdomen showed splenic and renal infarct. The blood culture grew Pseudomonas aeruginosa. A transthoracic echocardiogram showed aortic insufficiency with 13 mm mobile vegetation. The patient was started on ceftazidime and tobramycin and, later on, surgery was done for aortic valve replacement. His stay was complicated by multiple hemorrhagic emboli in the brain. This case highlights the importance of the early diagnosis and management of infective endocarditis caused by Pseudomonas aeruginosa.

Correlation of Ventilation-Perfusion (V/Q) Scan Results as Compared with Clinical Probability of Pulmonary Embolism in African American Population.

Introduction Current guidelines suggest the use of the more specific Wells' score could safely reduce the number of unnecessary scans. There is a lack of research to support whether these guidelines apply to the African American population. This study aims to evaluate the correlation of clinical pretest probability of pulmonary embolism (PE) with ventilation-perfusion (V/Q) scan results in a predominantly African American population and to test whether current guidelines based on studies conducted in other populations hold true in this group. Material and Methods A retrospective descriptive study to determine the diagnostic utility of the V/Q scan was conducted among patients who were seen during January 2012 to January 2016. The study population included patients who underwent a V/Q scan for evaluation of PE. One hundred and seventy-five charts were reviewed and 49 were excluded due to poor quality data. A review of the initial history, as well as discharge summaries, was performed. Wells' probability of PE was compared with the results of the scan. Laboratory tests and imaging studies were reviewed and analyzed. Result The median age of the study population was 63.02 ± 16.12 years. The majority of the study population, 121 patients (92.4%), was African American. Sixty-four (48.9%) VQ scans were done for a low clinical probability for pulmonary embolism as defined by the Wells' clinical score. The most common clinical presentations were shortness of breath (SOB) - 74 (58%), leg pain or swelling - 39 (29.8%), chest pain - 36 (27.4%), and syncope - 4 (3.1%). Sixty-two (96.9 %) patients with low clinical probability had low probability VQ scans (P = 0.03). Among the patients who underwent CT angiography and V/Q scanning, a low probability scan was noted in 25 patients with no pulmonary embolism on CT (96.2 %) (P = 0.006). Conclusions This study showed a strong correlation between low clinical probability and low probability V/Q scans and its utility to safely rule out PE in a predominantly black population. Studies conducted in other populations have detected similar findings.

Etiology and Age Distribution of Syncope in a Predominantly African-American Population.

BACKGROUND: Syncope, the sudden transient loss of consciousness due to multiple etiologies, usually has worse outcomes in African Americans compared with other races because of other comorbidities. This study aims to identify a correlation between the etiologies of syncope and age in a predominantly African-American sample population to facilitate future investigations with potentially improved specificity to address this condition. METHODS: We reviewed the medical records of 155 patients who presented with syncope concerns to the emergency department at our university hospital. After three charts were discarded due to poor data, the patients were divided into four age groups: <40 years old (25 patients), 40-60 years old (62 patients), 61-80 years old (44 patients), and >80 years old (21 patients). The etiology of syncope was reviewed in each case and categorized as either a vasovagal episode, orthostatic hypotension, pulmonary embolism, and related to cardio, neurologic, drug, or unspecified. RESULTS: For most of the patients in our study population, regardless of age, the etiology of syncope remained unspecified. Vasovagal related was the second most common etiology. The likelihood of having cardiac etiology under the age group of 40 is very low compared with those over 40 years (p = 0.026). Also, the incidence of pulmonary embolism is very low in all age groups with pulmonary embolism as a cause of syncope seen in only three patients (n = 3; 1.95%). CONCLUSIONS: Except for cardiac etiology being more likely in patients over age 40, we found no other correlation of age to syncope etiology. We also found that the etiology of syncope in African-American patients is similar to that of the general population. We recommend physicians to order a relevant workup, when clinical suspicion for syncope is present along with specific etiologies.

Supraventricular Tachycardia and Tricuspid Regurgitation in the Setting of Misplaced Implantable Port Catheter Tip.

We present the case of a 31-year-old female with a past medical history of B-cell leukemia, on maintenance chemotherapy administered via centrally placed implantable catheter port, who presented to the emergency room with fever, chills, and generalized body pain of one day's duration. After initial workup, the patient was admitted to the intensive care unit and managed for severe sepsis. The patient was found to have a new-onset 3/6 holosystolic murmur at the left lower sternal border. Furthermore, she developed an episode of supraventricular tachycardia that responded to adenosine. Transthoracic echocardiogram revealed severe tricuspid regurgitation but without valvular vegetation. Transesophageal echocardiogram further confirmed the absence of vegetation, in addition to visualizing the tip of the catheter tip in the right atrium and interfering with coaptation of the tricuspid valve. It was postulated that the severe tricuspid regurgitation and supraventricular tachycardia were caused by the catheter tip malposition. The catheter was subsequently removed. The patient's acute condition resolved and she was referred to cardiothoracic surgery for valvular surgery.

Acute Pericarditis: Descriptive Study and Etiology Determination in a Predominantly African American Population.

INTRODUCTION ---Acute pericarditis is the most commonly encountered manifestation of pericardial disease (incidence: 0.2 percent to 0.5 percent in hospitalized patients). However, data regarding manifestations, workup, and the management of acute pericarditis in the African American population is lacking. This study aims to collect and analyze more clinical data related to acute pericarditis in this understudied population. METHODOLOGY We conducted a retrospective chart review of all patients managed for acute pericarditis at a university hospital serving a predominantly African American population. A total of 78 charts were reviewed during the period of study from January 2011 to July 2016. Out of these, nine charts were excluded due to poor data. We descriptively analyzed data regarding presenting symptoms, underlying etiologies, co-morbidities, investigation results, management strategies, and prognoses. RESULTS We found an equal number of males and females in our study population. The most common comorbid conditions were hypertension, chronic kidney disease, and diabetes mellitus (in order of incidence). The most common presentation of symptomatic pericarditis consisted of chest pain, dyspnea, tachycardia, and tachypnea. Electrocardiogram (EKG) findings included diffuse ST elevation (15 percent) and sinus tachycardia (41 percent). Leukocytosis was seen in 15 percent of the patients. The most common etiology noted in our patient population was idiopathic and was treated with NSAIDS. CONCLUSION As compared to other populations, the incidence of uremic pericarditis and pericarditis secondary to cardiac etiologies is slightly higher in the African American population; however, the clinical presentation, examination and laboratory findings, as well as investigations, are remarkably similar.
