[Q]: Abstract: To establish the prevalence of Mycoplasma hominis and Ureaplasma urealyticum in infants up to 3 months of age with suspected sepsis, blood, cerebrospinal fluid, and urine specimens from 203 patients with clinical signs and symptoms of sepsis were cultured for Mycoplasma in addition to routine bacterial cultures. Proved bacterial infections were identified in 24 patients, four of whom had bacteremia. M. hominis and U. urealyticum were not isolated from any of the 191 blood and 199 CSF specimens tested. Of 170 specimens of urine cultured for Mycoplasma, M. hominis was isolated in six patients, U. urealyticum in nine patients, and both organisms in one patient. Twelve of the positive cultures were voided urine specimens, and four were suprapubic bladder aspiration specimens. Genital mycoplasmas appear to be uncommon causes of sepsis or meningitis in young infants. Further studies are required to assess their role in abnormal conditions of the urinary tract in childhood.

[Q]: Abstract: Plasma fibronectin levels were determined in 34 children admitted with severe infectious purpura. Fibronectin concentration was decreased in severe infectious purpura as in other sepsis, but there was no significant difference between shock and nonshock patients. Fibronectin levels were lower in children with ecchymotic or necrotic purpura on admission than in those with petechial purpura; they were lower in those who developed cutaneous sequelae, but it is not known if correction of fibronectin deficiency may limit the extent of purpura and prevent the cutaneous sequelae.

[Q]: Abstract: Doxepin hydrochloride, a tricyclic antidepressant, was evaluated in a double-blind, placebo-controlled crossover trial for the treatment of chronic idiopathic urticaria in 16 adults. Efficacy was evaluated by symptom scores, concomitant antihistamine use, and suppression of histamine- and codeine-induced wheal response. Doxepin-treated subjects experienced fewer lesions (p less than 0.001), less waking hours with lesions (p less than 0.01), lesser degree of itch and/or discomfort (p less than 0.001), and less swelling or angioedema (p less than 0.001) as compared to placebo-treated subjects. Doxepin-treated subjects required less daily concomitant antihistamine use (mean 0.13 tablets versus 1.48 tablets, p less than 0.05). Doxepin also significantly suppressed histamine- and codeine-induced cutaneous wheal response as compared to placebo. Lethargy was commonly observed but diminished with continued use. Dry mouth and constipation were also commonly observed. We conclude that doxepin is an effective agent for the treatment of chronic idiopathic urticaria.
