Background: Factors influencing the oral flora of premature infants have not been adequately investigated.

Objective: To investigate the effects of gestational age and of anti-bacterial therapy on the oral flora of premature infants.

Methods: Oral cultures were obtained at age 1 day and age 10 days from 65 premature infants, divided into three groups: a) 24 neonates of 30-34 weeks gestation who did not receive ABT, b) 23 neonates of 30-34 weeks gestation who received ABT, and c) 18 neonates < 30 weeks gestation who received ABT.

Results: Oral bacterial colonization increased from day 1 to day 10 of life. In 24-34 week neonates, gestational age did not affect early bacteremia or oral colonization at birth. Neither gestational age nor ABT affected late bacteremia or oral colonization at day 10. In 30-34 week neonates with ABT, the oral flora consisted mainly of non-Escherichia coli gram-negative bacteria, whereas those who did not receive ABT grew mainly alpha-hemolytic streptococci, Klebsiella pneumoniae and E. coli in neonates < 30 weeks who received ABT the oral flora were mainly coagulase-negative staphylococci. Oral colonization with anearobes was zero and colonization with fungi was minimal.

Conclusions: Acquistion of oral bacteria rose from day 1 to day 10 of life, regardless of gestational life or ABT. On day 10 of life, the spectrum of oral bacterial flora changed following ABT and consisted mainly of coagulase-negative Staphylococcus and non E. coli garm-negative bacteria. Oral colonization showed few fungi but no anaerobes. These microbiologic observations merit attention when empirical anti-microbial therapy is considered in premature infants suspected or having late-onset sepsis.

Background: The frequent coexistence of two or more sexually transmitted diseases in one patient has been reported in non-dermatological literature, mostly in languages other than English. Identification of Ureaplasma urealyticum, Chlamydia trachomatis and Mycoplasma hominis in men with other STDs is important, since these bacteria have been implicated in a variety of diseases such as non-gonococcal urethritis, premature rupture of fetal membranes, and infertility in female sexual partners of these patients.

Objective: To assess the frequency of concomitant STD, particularly urethral colonization of U. urealyticum, C. trachomatis and M. hominis, in men consulting for suspected STD-related symptoms.

Methods: All patients attending our dermatology clinic for STD-related symptoms during a 12 month period in 1996–97 underwent systematic clinical and laboratory screening for syphilis, gonorrhea, NGU, prostatitis, genital herpes simplex infection, Condyloma acuminatum, urethral carriage of U. urealyticum, C. trachomatis and M. hominis, as well as serological screening for HIV, and hepatitis B and C infections.

Results: A total of 169 men with STD-related symptoms were enrolled in the study. The following clinical diagnoses were established: NGU in 109 men, C. acuminatum in 40, genital herpes simplex in 10, prostatitis in 7, latent syphilis in 6, primary syphilis in 1, and Behcet’s disease in 1. No clinical evidence of STD was found in 13 patients. Of the 169 patients, 39 (23%) had two or more concomitant STDs, of whom 27 (69%) had C. acuminatum associated with one or more of the urethral pathogens. A positive U. urealyticum culture was found in 67.5% (27/40) of the men with C. acuminatum as compared to 42% (40/96) among the patients with NGU who did not have C. acuminatum (P=0.004, X² test). Conversely, the prevalence of C. acuminatum among patients positive for U. urealyticum was significantly higher than the prevalence among those who were negative – 27/75 (36%) vs. 13/94 (14%), P<0.0009, X² test. About half of the U. urealyticum-positive patients with C. acuminatum had no clinical signs or symptoms of urethritis.

Conclusion: Our findings suggest that patients with C. acuminatum should be assessed for U. urealyticum carriage and, when identified, their sexual contacts should be actively sought and treated.

Background: Ulcerative colitis begins in early childhood in 4% of cases. Medical therapy is non-specific, and as many as 70% of children will ultimately require surgery. The dynamic growth, physical and psychological changes that characterize childhood are severely compromised by the complications of ulcerative colitis and its therapy.

Objective: To review the outcome of children undergoing early surgery for ulcerative colitis at a tertiary medical center in Israel.

Methods: A retrospective review was conducted of all children operated on following failure of medical therapy for ulcerative colitis during a 5 year period.

Results: Eleven children underwent a J-pouch procedure with ileo-anal anastomosis in one to three stages. Postoperative complications included recurrent pouchitis in 5 patients, intestinal obstruction in 3, fistula with incontinence in one, stricture in one, and wound infection in 4. Follow-up revealed that most of the patients have three to four soft bowel movements daily. All currently enjoy normal physical activities and a rich social life.

Conclusions: The quality of life in children with ulcerative colitis was markedly improved following J-pouch surgery. This procedure was not associated with major complications. We recommend early surgery as an alternative to aggressive medical therapy in children with this disease.

Objective: To review the clinical presentation of gastrointestinal duplications and present our experience with such lesions over the past decade.

Methods: The records of all patients treated for gastrointestinal duplications at a tertiary hospital during 1987 through 1996 were collected, and relevant published literature reviewed.

Results: In the nine patients with gastrointestinal duplications, six were in the small bowel and one each in the cecum, colon and esophagus. Presenting clinical features were varied and often subtle. Perinatal ultrasonography, radioscintography and computerized tomography were useful in some cases, while in others the correct diagnosis was established only at surgery.

Conclusions: Alimentary tract duplications are uncommon, and may present as solid or cystic tumors, intussusception, perforation or gastrointestinal bleeding. A high index of suspicion is required when dealing with such cases. Appropriate investigations, including imaging techniques, should be directed toward adequate and planned surgery.
