ABSTRACT
Objective. To study histopathology of the thyroid and parathyroid glands in HIV-infected African Americans in the United States. Methods. A retrospective review of 102 autopsy cases done by the Department of Pathology at Howard University Hospital from 1980 through 2007 was conducted. The histopathological findings of the thyroid and parathyroid glands were reviewed, both macroscopically and microscopically. A control group of autopsy patients with chronic non-HIV diseases was examined. Results. There were 71 males (70%) and 31 females (30%) with an average age of 38 years (range: 20-71 y). Thirteen patients with abnormal thyroid findings were identified. Interstitial fibrosis was the most common histological finding (4.9%), followed by thyroid hyperplasia (1.9%). Infectious disease affecting the thyroid gland was limited to 2.9% and consisted of mycobacterium tuberculosis, Cryptococcus neoformans, and cytomegalovirus. Kaposi sarcoma of the thyroid gland was present in only one case (0.9%). Parathyroid hyperplasia was the most common histological change noted in the parathyroid glands. Comparing the histological findings of cases and controls, we found a similar involvement of the thyroid, with a greater prevalence of parathyroid hyperplasia in HIV patients. Conclusion. Thyroid and parathyroid abnormalities are uncommon findings in the HIV-infected African American population.
ABSTRACT
INTRODUCTION: Lemierre's syndrome is an extremely rare and almost universally fatal disease characterized as thrombophlebitis of the internal jugular venous system with subsequent metastatic infection. Fusobacterium necrophorum is the most common organism implicated in causation of Lemierre's syndrome. Group A Streptococcus has mainly been observed as a polymicrobial organism in the syndrome. We report a rare finding of a rare disease where Group A Streptococcus was the sole organism triggering Lemierre's syndrome. To our knowledge, this is only the third recorded patient with such an occurrence. CASE PRESENTATION: We describe a 9-year-old African American boy, who presented with otitis media and mastoiditis that culminated in Lemierre's syndrome. Isolates bore only Group A Streptococcus. The patient was appropriately treated and responded with full recovery from the syndrome. CONCLUSION: Since Lemierre's syndrome is classically detected by clinical diagnosis, these findings should prompt clinicians to consider Group A Streptococcus as an alternative catalyst. It should be pondered that patients who present with typical Group A streptococcal infections have the possibility for developing Lemierre's syndrome. Though this complication appears to be rare, early diagnosis and prompt intervention have proven critical in survival outcome. Indeed, what would seem to be a routine case of strep throat or otitis media easily treated with antibiotics could end up being an unalterable progression to death unless Lemierre's syndrome is immediately diagnosed and treated.
