RESUMEN

A sixty-eight-year-old male with a past medical history of recurrent cocaine use presented to the emergency department with recurrent diarrhea and was found to have a white blood cell (WBC) count of 1.9 × 109/L with agranulocytosis (absolute neutrophil count (ANC) of 95 cell/mm3). At admission, the patient disclosed that he used cocaine earlier during the day, and a urine drug screen tested positive for this. On hospital day one, the patient was found to have a fever with a maximum temperature of 313.6 K. After ruling out other causes and noting the quick turnaround of his neutropenia after four days of cocaine abstinence, the patient's neutropenia was attributed to levamisole-adulterated cocaine.

RESUMEN

Granular cell tumors (GCTs) have been described as neoplasms of Schwann cell origin. They are often benign and notably uncommon in the gastrointestinal tract. Recently, their incidence has become more common, likely as a result of increased colonoscopy screenings. Very few data exist regarding their potential for malignancy, but malignant GCTs have been reported. Here, we report the case of a young female patient who was diagnosed with an atypical GCT on the ileocecal valve with an overlying tubular adenoma which was found incidentally on colonoscopy. This represents the first known report of a GCT with atypical features on the ileocecal valve, as well as a rare case of overlying adenomatous changes. Due to the paucity of cases, there is no clear modus operandi for their management. Furthermore, it is not clear whether surgical or endoscopic interventions or simple observation may be most appropriate. Further studies are needed to evaluate the potential for malignancy of this tumor, as well as its management.

RESUMEN

In the last few decades many new anticoagulants (i.e direct thrombin and factor ten inhibitors) have been introduced with efficacy that rivals older drugs in the treatment of venous thromboembolism (VTE). However, for all their success, management of patients with recurrent thromboembolic events is still a challenging clinical scenario and not well addressed in the literature. We report the case of a young female with recurrent thromboembolisms in spite of using both newer agents and more conventional therapies. Ultimately, she is started on dual anticoagulation with warfarin and rivaroxaban without recurrence. This case report demonstrates that dual anticoagulants can be utilized in patients with recurrent VTE who fail single agent therapy. It also underscores the need for studies further elaborating on the utility of dual anticoagulants as a treatment modality for patients failing monotherapy.

RESUMEN

A 71-year-old female with a past medical history of Philadelphia chromosome-positive chronic myelogenous leukemia on imatinib therapy, Sjogren's syndrome, and hypothyroidism presents with acute hepatitis. After a comprehensive workup ruling out viral, infectious and metabolic etiologies imatinib is stopped which results in immediate improvement. The biopsy is consistent with drug-induced liver damage; the patient is started on oral prednisone and discharged. Unfortunately, our patient's liver function does not improve over the course of the next week and she is readmitted for hepatic and renal failure. During this second admission patient's condition continues to deteriorate with concomitant gastric bleeding, renal injury, and cellulitis. She ultimately chooses a palliative approach.

RESUMEN

Gastrointestinal cancer is one of the major causes of death worldwide. Hereditary gastrointestinal cancer syndromes constitute about 5-10% of all cancers. About 20-25% of undiagnosed cases have a possible hereditary component, which is not yet established. In the last few decades, the advance in genomics has led to the discovery of multiple cancer predisposition genes in gastrointestinal cancer. Physicians should be aware of these syndromes to identify high-risk patients and offer genetic testing to prevent cancer death. In this review, we describe clinical manifestations, genetic testing and its challenges, diagnosis and management of the major hereditary gastrointestinal cancer syndromes.
