Furuncular Myiasis Secondary to Dermatobia hominis Diagnosed With Point-of-Care Ultrasound in the Emergency Department.

Furuncular myiasis is a parasitic disease caused by the larvae of , or the human botfly, which burrow under the skin causing cystic lesions to develop. A six-year-old boy presented with multiple scalp lesions. The mother reported travel to Ecuador one month prior.

Mononuclear cell activation and decreased renal function in IgA nephropathy with crescents.

Our previous immunohistologic studies with monoclonal antibodies (mAb) showed that glomerular and interstitial accumulations of mononuclear cells (MNC) were common features of many types of proliferative glomerulonephritis, especially crescentic glomerulonephritis. The current study examined a series of patients with crescentic IgA disease, since IgA disease in general has a highly variable course and the presence of crescents is one indicator of likely progression to end-stage renal failure. We compared the intraglomerular and interstitial infiltrates within biopsies from patients with crescentic IgA nephropathy (N = 5) versus those with noncrescentic IgA (N = 18), or normal controls (N = 10).

Nonhepatitis B-associated liver disease in a renal transplant population.

The spectrum of liver disease in a population of 293 patients receiving 353 renal transplants (1971-1984) was reviewed. This study looked retrospectively at the histological features of liver disease in this population, and prospectively at the clinical and biochemical features of liver disease associated with renal transplantation. In all patients, infection with hepatitis B was excluded.

Leukocyte analysis using monoclonal antibodies in human glomerulonephritis.

The leukocyte subpopulations were analyzed within both the glomeruli and the interstitium in renal biopsies from 145 patients with various forms of glomerulonephritis. Cells were identified by monoclonal antibodies to leukocyte cell-surface antigens and immunoperoxidase labelling. Leukocytes, as defined by a monoclonal antibody to the leukocyte common antigen (PHM1), were present in normal, human renal tissue in both glomeruli (2.

Monoclonal antibody analysis of glomerular hypercellularity in human glomerulonephritis.

To determine the contribution of infiltrating circulating leucocytes to glomerular hypercellularity, and to further investigate the immune and inflammatory mechanisms involved in human glomerulonephritis, a series of renal biopsies were evaluated using cell-specific monoclonal antibodies. In ninety-three renal biopsies from patients with glomerulonephritis, intraglomerular leucocytes were identified by immunoperoxidase localization of monoclonal antibodies to the leucocyte-common antigen, and antigens characteristic of T-cell and T-cell subsets, B-cells, monocytes and granulocytes. Normal glomeruli contained a mean of 2 leucocytes, predominantly monocytes, per glomerular cross-section.
