Localized lipoatrophy (atrophic connective tissue disease panniculitis).

Four patients with localized lipoatrophy were observed. All were female, and three were children. Lymphocytic panniculitis was observed in early biopsy specimens of all four cases, with focal histiocytic granulomas in one case. Later biopsy specimens in three patients showed that the inflammation was transient. These pathologic findings and reports of lipodystrophies associated with nephritis, hypocomplementemia, and other inflammatory or immunologic disorders offer an opportunity for histologic and immunologic study of such patients. Localized lipoatrophy may represent the end stage of panniculitis in a localized expression of connective tissue disease.

Metastatic malignant melanoma transplanted via a renal homograft: a case report.

A case of transplantation of a malignant melanoma via a cadaver renal homograft is presented. The recipient developed a widespread malignancy ninteen months after renal transplantation. At autopsy the tumor was diagnosed as a malignant melanoma. Autopsy of the donor had previously revealed a spindle cell malignancy in the spleen. It is postulated that the splenic tumor in the donor represents a spindle cell variant of malignant melanoma, and hence this malignancy was inadvertently transferred to the recipient via the renal homograft.

Hospitals respond to water loss during the Midwest floods of 1993: preparedness and improvisation.

The Midwest floods of 1993 presented multiple emergency preparedness challenges to the six metropolitan medical centers in Des Moines, Iowa. As floodwaters overcame the Des Moines Water Treatment Plant, medical centers were faced with the task of responding to imminent water loss and its associated impact on patient care services and facility operations. Many clinical services were cancelled or diverted to alternate facilities. Ancillary resources were identified and implemented to maintain essential operations. Through effective emergency preparedness and creative improvisation, medical centers were able to overcome the initial crisis, sustain primary services, and ensure continued quality patient care. The article describes how sudden and prolonged water loss affected Des Moines hospitals. It also discusses aspects of hospital emergency preparedness that contributed to successful response.

Gene rearrangement analysis in lymphoid neoplasia.

Current uses for gene rearrangement analysis in clinical dermatology are listed in Table 3. This technique is useful for determining the existence of clonal populations within a background of polyclonal lymphoid cells; therefore, it is helpful in the diagnosis and staging of patients with CTCL and PTCL. Although dual genotypes do occur, this technique is usually capable of determining lineage in a clonal lymphoid infiltrate and elucidating and characterizing the etiopathogenesis of certain neoplasms. On the basis of this review of the literature and our own experience, we conclude that gene rearrangement analysis shows great promise for monitoring response to therapy and detecting progression or relapse in patients with CTCL and PTCL. With the recent technology of PCR, it is possible to amplify specific sequences of DNA, detect molecular alterations in individual malignant T cells, and even identify exogenous retroviral gene sequences in tissues of patients with CTCL. Although gene rearrangement analysis has supported or established the clonal nature of lymphomatoid papulosis, pre-Sézary syndrome, granulomatous slack skin syndrome, and follicular mucinosis, the clinical significance of these findings is not yet clear. In the case of primary cutaneous B-cell lymphoma and its benign counterpart, B-cell pseudolymphoma, further investigation will be needed to determine the clinical significance of clonal rearrangements.
