A 58-Year-Old Woman with Gallstones, Chronic Pancreatitis, and Pancreatic Pseudocyst Presenting with Pleural Effusion Due to a Pancreaticopleural Fistula.

BACKGROUND Pancreaticopleural fistula (PPF) is a rare complication of acute and chronic pancreatitis. PPF results from the release of pancreatic enzymes, either from a damaged pancreatic duct or pancreatic pseudocyst. This report is of a 58-year-old woman with a history of chronic pancreatitis associated with gallstones who had a known pancreatic pseudocyst that was being managed conservatively and who presented to the Emergency Department with pleural effusion due to a PPF. CASE REPORT A 58-year-old woman with past medical history of gallstone pancreatitis with subsequent development of pancreatic pseudocyst (being managed conservatively) presented with a 2-week history of progressive exertional shortness of breath. Physical examination indicated decreased breath sounds on the right lower lung fields. A chest X-ray revealed possible subphrenic free air. Laboratory test results were unremarkable except for elevated D-dimer levels. Computed tomography angiography revealed a large right-sided pleural effusion, which led to thoracentesis and the results illustrated elevated amylase levels. Magnetic resonance cholangiopancreatography was done, which showed pancreatic pseudocyst and possibly a fistula. Pancreatic enzymes were not checked in pleural fluid, as diagnosis was established with the presence of amylase and imaging findings. The patient felt better clinically after thoracentesis with volume removal and was discharged. She later underwent endoscopic ultrasound, which revealed a pancreatic duct leak requiring stent placement. CONCLUSIONS Pleural effusions rarely occur secondary to PPF. Physicians must be wary of the presentation, especially in patients with a history of a conservatively managed pancreatitis pseudocyst. Early diagnosis and management can lead to prevention of long-term morbidity and mortality.

Hypercalcaemia Caused by Sunflower Seeds and Calcium Carbonate Supplements.

INTRODUCTION: Hypercalcaemia is commonly associated with malignancy or endocrinological disorders. However, sometimes it can occur due to increased oral intake of calcium. We present an interesting case of hypercalcaemia due to ingestion of sunflower seeds and calcium carbonate supplements. CASE DESCRIPTION: We present the case of a 53-year-old man with history of T-cell lymphoma and gastroesophageal reflux disease who was brought to the emergency room due to altered mental status, nausea, vomiting and abdominal pain. His calcium level was 3.30 mmol/l (normal value 2.23-2.58 mmol/l). Imaging studies were unremarkable. The patient was hydrated with normal saline and calcium levels improved. Once he was more coherent, he disclosed that he had consumed significant amounts of sunflower seeds and calcium carbonate supplements, which were considered to be the cause of his hypercalcaemia. CONCLUSION: Hypercalcaemia is common and can lead to critical illness. Although hypercalcaemia is frequently associated with endocrinological disorders, sometimes the presentation is secondary to increased intake. The consumption of sunflower seeds and antacids containing calcium carbonate can cause symptomatic hypercalcaemia. It is important to recognize rare causes of hypercalcaemia in order to treat it in a timely manner and prevent recurrence. LEARNING POINTS: Hypercalcaemia can occur due to excessive intake of sunflower seeds and calcium carbonate supplements.Hydration and cessation of oral supplements can result in rapid reversal of hypercalcaemia.It is important to obtain a complete history in order to determine the aetiology of hypercalcaemia.

A Case of Evans Syndrome and Unstable Angina.

Evans syndrome (ES) is characterized by autoimmune hemolytic anemia (AIHA) and immune-mediated thrombocytopenia. It is more common in the pediatric population than in adults. ES has been reported to be associated with thrombotic events and rarely can lead to acute coronary syndrome (ACS). There have been only a few reported cases of ACS secondary to ES. We present an interesting case of ES with unstable angina (UA) which had a limited response to oral and intravenous (IV) steroids requiring rituximab. A 64-year-old male with past medical history significant for hypertension, hyperlipidemia, diabetes mellitus and coronary artery disease, presented to the emergency room complaining of a 2-week history of chest pain, shortness of breath and hematuria. Physical examination indicated splenomegaly but was otherwise unremarkable with no petechiae or rash. Labs showed hemoglobin of 9.6 g/dL, platelet count 58 × 103/µL, troponin < 0.03 ng/mL, lactic acid 2.5 mmol/L and with parameters indicative of hemolysis, evidenced by elevated lactate dehydrogenase, low haptoglobin and elevated bilirubin levels. Electrocardiography (EKG) demonstrated ST depression in leads I, aVL, V5 - V6 and T wave inversions in lead III and aVL, which were new compared to previous EKG. Peripheral blood smear indicated spherocytes. Direct antiglobulin test was positive for immunoglobulin G (IgG). Patient was admitted for ES and initially treated with oral prednisone 80 mg daily. He was also diagnosed with UA thought to be possibly secondary to ES. He then underwent cardiac stress test which showed mild reversible inferior apical ischemia. Cardiac catheterization revealed 95% stenosis of proximal left circumflex artery requiring single drug eluding stent placement and dual antiplatelet therapy. Patient continued to have anemia despite blood transfusions, although platelet count improved. Prednisone was transitioned to high-dose IV dexamethasone, and patient was also started on rituximab which resulted in stabilization of anemia. The presentation of ES with ACS is a rare occurrence. ACS can be challenging to manage as stent placement may be required followed by dual antiplatelet therapy. Treatment of ES involves steroids followed by rituximab, IV immunoglobulin (IVIG) or splenectomy for non-responsive cases. Early intervention and management can prevent mortality and morbidity.

An Interesting Case of Critical Spontaneous Ureteral Rupture.

Spontaneous rupture of the ureter in an uncommon presentation. We present a case of an 85-year-old female patient with a past medical history significant for hypertension and hyperlipidemia who presented to the emergency room (ER) due to abdominal pain and nausea. Computed tomography (CT) of abdomen and pelvis revealed proximal ureteral and ureteropelvic junction rupture with fluid within the left retroperitoneum and pelvis. No clear etiology was identified. The patient had a left percutaneous nephroureteral catheter tube (PNCT) placed in addition to being given broad-spectrum antibiotics for possible infection. She was noted to improve and was discharged with outpatient follow-up for tube removal. Our patient presented with a rupture of the ureter; however, the source remained elusive. CT scan assisted with the diagnosis but there is no evidence of hydronephrosis or mass. There are no clear treatment guidelines for spontaneous ureteral rupture as the presentation is rare. Treatment may involve percutaneous drainage and possibly antibiotics for concurrent infection. Surgical intervention may be required in cases where severe complications arise. Early diagnosis and management may prevent long-term morbidity and mortality.

Pancoast-Tobias Syndrome: A Unique Presentation of Lung Cancer.

A 65-year-old man with 50 pack-year smoking history presented to the emergency department for evaluation of upper back and right shoulder pain secondary to a fall. Physical examination was notable for anisocoria with a constricted left pupil (miosis), mild ptosis of the left eyelid, and bilateral shoulder pain, right more than left, with both passive and active movements. Chest computed tomography identified a soft tissue mass at the left lung apex with extension into the pleural surface, associated with destructive osseous changes of the right scapula, adjacent ribs, and thoracic vertebral bodies. Imaging of the brain revealed multiple masses suspicious of metastatic brain lesions. Biopsy of the right supraclavicular lymph node revealed lung tissue adenocarcinoma and negative Kirsten rat sarcoma viral oncogene homolog (K-Ras), epidermal growth factor receptor (EGFR), B-raf proto-oncogene (BRAF), C-ros oncogene 1 (ROS1), and anaplastic lymphoma kinase (ALK) rearrangement. Recognizing Pancoast syndrome in patients with significant smoking history, anisocoria, and shoulder pain is crucial for identifying the underlying etiology and expediting the treatment.
