BACKGROUND: Despite good results in the treatment of most port-wine stains (PWS) with continuous-wave visible-light lasers, light PWS and those in certain locations respond less favorably and have a higher risk of scarring. Robotized scanning devices such as the Hexascan device have been developed for continuous-wave laser sources to produce greater target specificity, to increase reproducibility of results, and to decrease the incidence of adverse effects. OBJECTIVE: The purpose of this study was to compare the effects of the same wavelength of light (585 nm) on test sites within PWS with the flashlamp-pumped pulsed dye laser and a continuous-wave tunable dye laser scanned through a Hexascan robotized scanning device. METHODS: Two adjacent, noncontiguous sites within PWS were treated in 29 patients, one site with the flashlamp-pumped pulsed dye laser and the other with an argon-pumped continuous-wave tunable dye laser affixed to a Hexascan device. RESULTS: Twenty-eight patients completed the study. The pulsed dye laser was found to be superior to the continuous-wave dye laser with the Hexascan device in 45% of patients, whereas the continuous-wave tunable dye laser with the Hexascan device was considered superior in 15%. There was no difference in the remaining 40%. Undesirable side effects were infrequent with both treatments. There was no significant difference in hypopigmentation or atrophic and hypertrophic scarring, but hyperpigmentation was more frequent with the continuous-wave dye laser with the Hexascan device. CONCLUSION: Both the pulsed dye laser and continuous tunable-wave dye laser with the Hexascan device produce slight lightening after one treatment. The pulsed dye laser produces slightly greater lightening than the continuous-wave tunable dye laser with the Hexascan device 6 weeks after treatment of test areas within PWS in 40% of those treated. It also produced slightly less hypopigmentation and hyperpigmentation

Tuberculosis in children 10 years of age and younger: three decades of experience during the chemotherapeutic era
Nemir, R L; O'Hare, D
1991 Aug;88(2):236-241, Pediatrics
The 863 patients, aged 10 years and younger, treated at the Children's Chest Clinic of Bellevue Hospital during three decades (1953 through 1981) clearly indicated the success of antituberculosis therapy. There were no deaths from tuberculosis. Early treatment is associated with a reduction in the serious forms of disease, eg, meningitis, miliary disease, and bone infections, and with preventing death. Medication was well tolerated: only 1.1% of the patients had adverse reactions, all of which were reversible. Consistent compliance with medication of only 62% of patients is a challenge to the medical profession. Only 22.5% of mycobacterial cultures were positive. Long-term follow-up of patients was rewarding: seven pregnancies with healthy mothers and babies, and no reactivation of tuberculosis by later infections, even those such as measles or pneumonia. The severity of disease was related largely to patient's age (3 years and younger) and intimacy of contact, the highest rate being when the mother was the contact. The long-term experiences emphasizes the value of early identification, therapeutic compliance, and comprehensive contact, tracing in the future elimination of tuberculosis. Prophylactic therapy and close observation should be considered for contacts, especially those exposed to human immunodeficiency virus infections and addicted to drugs

Congenital tuberculosis. Review and diagnostic guidelines
Nemir, R L; O'Hare, D
1985 Mar;139(3):284-287, American journal of diseases of children
A review of congenital tuberculosis was prompted by the successful treatment of this disease in a unique patient. She was followed up for 27 years, and gave birth to two normal, uninfected newborns despite calcifications throughout her abdomen and elsewhere. Tuberculosis of the newborn, whether acquired congenitally or postnatally, is preventable. Recommendations for diagnosis of congenital tuberculosis are given. Determination of the mother's tuberculin status or suitable testing should be done early in pregnancy. Endometritis is cited as an unrecognized source of fetal infection
