A young patient with Graves' disease presenting with a triad of heart failure, pancytopenia, and jaundice: A case report.

Key Clinical Message: Graves's disease must be treated promptly to avoid serious sequelae such as cardiomyopathy, liver injury, and pancytopenia. Early initiation of antithyroid medications and beta blockers could not be overrated even in the presence of these complications. Abstract: Graves' disease causes a large spectrum of clinical manifestations. Delayed diagnosis and management of Graves' disease could lead to serious systemic sequelae. We describe a case of a young man who presented with progressive cough, increased abdominal girth and ankle swelling for a few months. On examination, he had jaundice, bilateral exophthalmos, diffuse goiter, ascites, and significant lower limb edema. Laboratory investigations showed increased Thyroxin level with a suppressed thyroid stimulating hormone and positive anti-thyrotropin receptor antibodies. Also, the patient had pancytopenia, coagulopathy and cholestatic pattern of elevated liver enzymes. Echocardiography demonstrated mildly reduced left ventricular function with diastolic dysfunction, but electrocardiogram did not show atrial fibrillation. Despite the concerns about using antithyroid medications in patients with impaired liver function tests and pancytopenia, the patient improved dramatically without worsening of his hematological or biochemical parameters. Early initiation of antithyroid medications and beta blockers is essential for patients who are newly diagnosed with hyperthyroidism.

Subacute infective endocarditis presenting with an isolated splenic infarction.

Background: Subacute endocarditis usually presents over a period of weeks or months. Symptoms usually include low grade fever, and generalized symptoms of malaise, anorexia, weight loss. Here we present a case of subacute endocarditis presenting solely as acute left hypochondrial pain, which was found to be splenic infarct. Typical symptoms of subacute endocarditis were absent in our patient. Case report: A 48-year-old Yemeni gentleman presented to the emergency department with acute and severe left hypochondrial abdominal pain for a few hours. Blood investigations revealed normal blood count differential, renal, liver function, and electrolyte levels. CT abdomen with contrast showed large focal wedge-shaped splenic lesion representing splenic infarct. Initial workup was negative for an underlying etiology. TEE showed a spherical mobile mass attached to the aortic valve with moderate to severe aortic regurgitation. Subsequently, 3 sets of blood cultures were sent and revealed growth of streptococcus viridians in all bottles. The patient received IV antibiotics as a treatment of endocarditis. Conclusion: This case highlights how subacute endocarditis presented as splenic infarction, with the absence of the typical infectious symptoms. In case of splenic infarction with unclear source or etiology, it is reasonable to investigate thoroughly for infective endocarditis preferably with TEE.

A case report of Pasteurella multocida meningitis in a patient with non-traumatic skull base defect.

BACKGROUND: Pasteurella multocida is a gram-negative coccobacillus that is primarily found in oropharynx of dogs, cats and other animals. It causes infections in human beings through contact with animal saliva in the form of licks, bites and scratches of animals colonized by the bacteria. Meningitis due to Pasteurella multocida is rare in immunocompetent individuals. We report a case of meningitis due to Pasteurella multocida in an immunocompetent patient. CASE REPORT: A 30-year-old gentleman presented with 2-day history of fever and neck stiffness. 6 weeks earlier, he was treated as a case of bacterial meningitis. During that hospital stay, he was diagnosed to have bony defect in the sellar floor based on MRI head performed to evaluate for a prolonged history of CSF rhinorrhea. He was discharged and scheduled for an elective endoscopic endonasal/open repair of the skull base defect after resolution of meningitis. CSF findings during current admission also showed features of bacterial meningitis. CSF culture showed Pasteurella multocida sensitive to penicillin, ampicillin and ceftriaxone. Retrospective history revealed patient's contact with stray cats as he used to feed them but there was no history of licks, bites. He was treated with intravenous ceftriaxone 2 g twice a day for 14 days with complete resolution of his symptoms. CONCLUSION: Pasteurella multocida is an important cause of bacterial meningitis in patients with skull defect. Patients with traumatic or non-traumatic bony defect of skull should avoid contact with dogs and cats to prevent the spread of infection the central nervous system.
