Obesity is currently a worldwide pandemic, with overweight (body mass index [BMI] ≥25 kg/m2) and obesity (BMI ≥30 kg/m2) estimated at 35% and 12% of the global adult population, respectively. According to data collected from the United States National Health and Nutrition Examination Survey, approximately 68.8% of US adults are overweight or obese. Additionally, a large burden of health care costs can be attributed directly to obesity as well as multiple, potentially preventable, comorbidities such as cancer, cardiovascular disease, and diabetes. As a result, national and international organizations, such as the US Centers for Disease Control and World Health Organization, have made halting the rise of the obesity epidemic a top priority. Pharmacists, commonly considered one of the most trustworthy and accessible health care professionals, are ideally situated to provide counseling for weight and lifestyle management. This review presents examples of pharmacist-led as well as collaborative practices that have been somewhat successful in educating and monitoring patient progress in attaining weight-loss goals. Common barriers and potential solutions to administration of lifestyle counseling and monitoring programs, such as limited pharmacist time and resources, lack of expertise and/or confidence in program administration, and patient perception and awareness, are also discussed.

Primary aortic sarcoma is a rare and aggressive malignancy with only approximately 190 cases reported in the literature. While angiosarcoma and intimal sarcomas represent an estimated 67.7% of malignant aortic tumours, spindle cell sarcomas are even more exclusive, consisting of only 0.9% of malignant aortic tumours. Differentiated from other malignant aortic tumours, spindle cell sarcomas are of mesenchymal origin and usually express vimentin and osteopontin. Clinical presentations are variable and nonspecific, ranging from back pain, abdominal pain or elevated blood pressure, misleading to differentials like pulmonary emboli or aortic aneurysms such as in our case here. In this article, we discuss the finding of an extremely rare aortic sarcoma masquerading as a pulmonary embolism. The patient underwent surgical resection; however, the course was complicated by the development of brain metastases and intracranial haemorrhage. The literature is expanding regarding the evolution of adjuvant chemotherapy and radiation therapy in the treatment of these patients. The exact pathogenesis of spindle cell sarcomas is unknown but thought to be related to the MDM2-p53 pathway. The development of spindle cell sarcomas may be related to Li-Fraumeni syndrome, which should be on the differential for these patients. This case highlights the importance of identifying aortic sarcomas in patients who present with signs and symptoms of peripheral embolization as the diagnosis can be easily misconstrued for thrombus or aortic aneurysm, leading to a delay in proper and timely management. We herein emphasize that aortic sarcomas should be included in the clinician’s working differential due to the poor prognosis and outcomes that these aggressive tumours carry.

T-cell/histiocyte-rich large B-cell lymphoma (THRLBCL) is an extremely rare morphologic subtype of diffuse large B-cell lymphoma (DLBCL), accounting for only 1-3% of total cases. It is considered an aggressive lymphoma with a poor prognosis. Hypercalcemia has been described as an uncommon presenting symptom of patients with DLBCL in several case reports. Here, we report an unusual case of severe hypercalcemia in a patient who was ultimately diagnosed with T-cell/histiocyte-rich B-cell lymphoma. A 69-year-old male patient presented to our hospital with nausea, vomiting, weakness and unintentional weight loss. His initial blood tests showed a serum calcium level of 16.1 mg/dL and serum creatinine level of 3.25 mg/dL. He had high intact parathyroid hormone (PTH, 6.8 pg/mL), mildly elevated 25-hydroxyvitamin D and serum PTH-related peptide (PTHrP). To exclude malignancy, computed tomography (CT) scans of the chest, abdomen and pelvis were performed which were unremarkable. A bone marrow biopsy was performed to detect any hidden hematologic malignancy which showed large mononuclear cells with prominent nucleoli and occasional Reed-Sternberg cells, consistent with the diagnosis of THRLBCL. Subsequent positron emission tomography demonstrated diffuse fluorodeoxyglucose (FDG) uptake. This case reports a unique presentation of a rare subtype of non-Hodgkin’s lymphoma. We highlight the importance of pursuing a thorough workup for causes of hypercalcemia as well as understanding the underlying mechanisms of severe hypercalcemia in malignancy.

Gastrointestinal stromal tumors (GISTs) are the most common type of mesenchymal neoplasm of the gastrointestinal tract but consist of only 1% of all primary gastrointestinal neoplasms. Differentiated from other spindle cell tumors, GISTs are uniquely positive for CD117 expression which allows for molecular targeting therapy with imatinib mesylate (Gleevec). Clinical presentations are variable, ranging from asymptomatic to vague symptoms of abdominal pain, early satiety, abdominal distention or gastrointestinal bleeding. Very rarely, patients can present with tumor-bowel fistula and intra-abdominal abscesses. In this article, we discuss a rare presentation of a middle-aged male with multiple liver abscesses found to have a primary small bowel GIST. This patient received prompt intravenous antibiotics; however, hepatic abscesses can be easily misinterpreted as cystic hepatic metastases which can delay appropriate therapy. Streptococcus anginosus was found to be responsible for the formation of the liver abscesses visualized on computed tomography (CT) scan. Similar to Streptococcus bovis, knowledge in the literature is arising about the association between S. anginosus and gastrointestinal malignancies. This case highlights the importance of identifying concomitant primary GISTs with intra-hepatic abscesses, as these lesions can be easily misconstrued as liver metastases and consequently mismanaged. We herein emphasize that hepatic abscesses are a potential sequela of GISTs and should thus prompt further investigation for potential malignancies, if warranted, so that there is no delay in treatment of these gastrointestinal tumors.
