Twenty-four hour growth hormone secretion in a patient with Werner's syndrome.

OBJECTIVE: To assess the 24-h endogenous secretory growth hormone (GH) profile and serum insulin-like growth factor-I (IGF-I) response to exogenous recombinant human growth hormone (rhGH) in a patient with Werner's syndrome. DESIGN: Blood sampling every 20 min for 24 h followed by three daily injections of growth hormone. SETTING: General Clinical Research Center. PATIENTS: Single patient with Werner's syndrome. MEASUREMENTS: Serum GH and IGF-I. RESULTS: Growth hormone pulses were absent during the 24-h monitoring period. Likewise, integrated GH concentrations were very low at 0.25 mu min/mL, and no peaks occurred after sleep onset. Following single daily administration of rhGH, serum GH and IGF-I rose. CONCLUSIONS: Our findings support previous but less extensive studies suggesting patients with Werner's syndrome have reduced growth hormone levels. Preliminary investigations using rhGH in patients with Werner's syndrome should be considered.

Photodynamic therapy using SnET2 for basal cell nevus syndrome: a case report.

A 26-year-old man with basal cell nevus syndrome presented to the Rocky Mountain Cancer Center (Denver, Colorado) for treatment of several basal cell carcinomas with photodynamic therapy using tin ethyl etiopurpurin (SnET2). The patient was of northern European descent, had type I skin (always burns, never tans), and had a 10-year history of multifocal basal cell carcinomas. The patient had a family history of Gorlin's syndrome (basal cell nevus syndrome); the syndrome had been diagnosed in this patient in 1985. The patient was enrolled in a Phase I/II clinical trial. He was given 1.2 mg/kg (94 mg total) of SnET2 via intravenous infusion; he returned to the clinic the following day for red light application. Thirteen lesions, in 12 treatment fields, were illuminated with light totaling 200 J/cm2 at a fluence of 150 mW/cm2. At the 3-month follow-up examination, all tumors were graded as having a complete response by modified AIDS Clinical Trial Guidelines oncologic standards. No evidence of recurrence has been noted during the 6-month follow-up period.

Mortality among forest and soil conservationists.

The mortality of forest conservationists and soil conservationists in the United States Department of Agriculture (USDA) who died during January 1, 1970-December 31, 1979 (N = 1,411 white males) while actively employed or while receiving a pension was evaluated. The proportionate mortality analysis was used to identify cancers that might be elevated in this occupational group compared to the total U.S. white male population, whereas case-control analyses more rigorously evaluated the disease association with occupation. Controls were selected from employees at USDA who died of any cause of death other than that cause of death represented by the case. In case-control analyses, non-Hodgkin's lymphoma (NHL) and colon cancer demonstrated a statistically significant linear trend (p less than .05) with duration of employment as either a forest or soil conservationist, which suggests an occupational etiology for both diseases. Soil conservationists who were last employed after 1960 experienced significantly elevated risks for NHL (OR = 2.6) and colon cancer (OR = 1.8), whereas those last employed before 1960 were not at an increased risk. Among forest conservationists, the risk for both NHL and colon cancer appeared to be elevated before and after 1960.
