RESUMEN
Central nervous system (CNS) histoplasmosis occurs in 5-20% of all cases and is most commonly seen in immunosuppressed patients who have acquired immunodeficiency syndrome (AIDS) or have received organ transplant. The prevalence of histoplasmosis in patients greater than 65 years old between the years of 1999-2008 in the state of Texas was about 2-3 cases per 100,000 patients year. Since 1990 with the discovery of Triazoles, itraconazole (ICZ) has become the standard initial and suppressive therapy in patients with mild-moderate histoplasmosis without CNS involvement. However, poor penetration of ICZ into the brain, in vitro fluconazole resistance and lack of controlled-trials pose challenge in the treatment of cerebral histoplasmosis.
RESUMEN
Dahl's sign, a clinical sign in which areas of thickened and darkened skin seen on the lower thighs and/or elbows, is seen in patients with severe chronic respiratory disorders such as chronic obstructive pulmonary disease (COPD), interstitial lung disease, congestive heart failure (CHF), and chronic moderate to severe persistent asthma. The aim of our present report is to create awareness and encourage providers to lay emphasis on physical examination in every medical examination that can give clues to the severity of the underlying disorder.
RESUMEN
Chorea is a disorder characterized by irregular, involuntary, hyperkinetic movements and has various causes. One unusual cause is hyperglycemia. This case involves a 76-year-old diabetic Caucasian female who developed gait disturbances, hemichorea of the face and limbs, and slurred speech over two to three weeks. She was found to have glucose level of 690 mg/dL with HbA1c of 14.7%. Head CT demonstrated hyperdensity in the left basal ganglia and mild involvement of right basal ganglia. Treatment with insulin alleviated her symptoms. The exact pathophysiology is unknown; however, many theories exist.
RESUMEN
Calciphylaxis is a rare and serious disorder seen most in end-stage renal disease (ESRD) patients on dialysis. It is associated with the calcium deposits in small and medium blood vessels of the skin and subcutaneous tissues resulting in painful skin lesions, plaques, ulcerations, gangrene, and secondary infections. The aim of our present report is to create awareness and encourage providers to consider calciphylaxis in the differential diagnosis of cellulitis in the appropriate clinical setting.
RESUMEN
UNLABELLED: BACKGROUND AND CASE REPORT: Polyarteritis Nodosa (PAN) is a systemic necrotizing vasculitis that affects medium-sized and occasionally involves small arteries leading to the disruption of the internal and external elastic lamina and contribute to the development of aneurysms. Aneurysms develop at bifurcation of major blood vessels; they are prone to thrombosis, rupture and haemorrhage. Retroperitoneal haemorrhage around kidneys was previously reported in patients with PAN. We report a case of massive retroperitoneal bleeding from inferior pancreaticoduodenal artery aneurysm rupture in a 70-year-old female with PAN. CONCLUSION: Prognosis of untreated PAN is very poor with 20% 5 year survival rate, therefore early recognition of the disease will prevent catastrophic complications and improves survival.
