[Pseudo-"isolated" intestinal perforation in a very low birth weight infant: exceptional presentation of Hirschsprung's disease].

Intestinal perforations in preterm newborn are characterized with high morbidity and mortality rates. They often are associated with necrotizing enterocolitis and seldom correspond to idiopathic spontaneous intestinal perforation. Perforations upstream of an intestinal organic obstruction (atresia), or of a functionnal obstruction (meconium-ileus, Hirschsprung disease) have been considered to be rare in preterm newborns. We report a case of caecal perforation with a pneumoperitoneum which occurred at 5 days of life, in a 28-week gestational age infant, that was treated by cecostomy. There were no signs of necrotizing enterocolitis. At 43 days of life, the preoperative contrast enema study revealed a left colon transition zone, suggesting a Hirschsprung disease, which was confirmed by rectal biopsies. Transanal pull-through was performed. There were no postoperative complication. This case demonstrates that an isolated intestinal perforation in very preterm newborn can reveal a Hirschsprung disease, especially if it occurs in the caecum.

Hypocomplementemic urticarial vasculitis or systemic lupus erythematosus?

The 2 patients presented here showed the typical signs of hypocomplementemic urticarial vasculitis syndrome (HUVS). During follow-up, there was an inverse correlation between anti-C1q autoantibody titer and C1q antigen concentration in serum in both patients over a period of 2 years. The first patient had nephritis characterized by immune deposits in glomeruli and around the tubules. The histological findings, C1q deposits, and presence of tubuloreticular inclusions in capillary endothelial cells suggested a disease process identical to systemic lupus erythematosus (SLE). The second patient, after a lag phase of 2 years, fulfilled a fourth American College of Rheumatology criteria for SLE when she developed anti-double-stranded DNA antibodies. HUVS and SLE overlap, and the criteria for identifying HUVS as an entity distinct from SLE are lacking.

Is there a relation between risk groups or initial CD4 T cell counts and prevalence of seborrheic dermatitis in HIV-infected patients?

OBJECTIVES: (i) To investigate whether there is a difference in the prevalence of seborrheic dermatitis (SD) between homo- or bisexual HIV-infected patients and HIV-infected intravenous drug users, (ii) to study whether the initial CD4 T cell count at the first positive HIV test is of any significance for the prevalence of SD and furthermore to analyze whether (iii) antiretroviral treatment influences the prevalence and time course of SD. PATIENTS AND METHODS: Since 1992 we have been following, within the scope of the Swiss HIV Cohort Study, a group of individuals with proven HIV infection. In this study all HIV-infected patients belonging either to the risk group of homo- or bisexuals or that of intravenous drug users were included for further analysis. RESULTS: We included 226 men and 51 women. The ages ranged from 17 to 68 years (mean 30.1). One hundred and forty-four were homo- or bisexual men and 133 (82 men and 51 women) were intravenous drug users. Out of these 277 HIV-infected patients, 66 (23.8%) had SD at baseline and 7 (2.5%) developed SD during the observation period (male:female = 68:5). CONCLUSION: In our study we found that (i) the risk group influences the prevalence and time course of SD, yet that (ii) neither the initial CD4 T cell count nor (iii) antiretroviral treatment is of any significance.

Delayed-type hypersensitivity to a nonionic, radiopaque contrast medium.

BACKGROUND: True allergic reactions to iodinated radiocontrast media are rare, and only a few well-documented cases of delayed-type hypersensitivity reactions caused by contrast media have been described. METHODS: We report a 61-year-old patient in whom percutaneous transluminal coronary angioplasty (PTCA) was performed with iopamidol, a nonionic contrast medium. Seven days later, the patient developed generalized maculopapular exanthema. Repeated patch tests with several iodinated agents were performed. RESULTS: A first patch test with iopamidol was positive. Repetition of the patch tests showed positive results to iopamidol as well as to iohexol and ioversol, two other nonionic contrast media, but not to other iodinated substances. Three months later, PTCA was repeated, and iopamidol was used again. Despite premedication, pruritic macular exanthema developed 1 day later. Whether iopamidol or trometamol -- an additive substance in the contrast medium -- was causative could not be determined, since a third set of patch tests was negative. CONCLUSIONS: Delayed-type hypersensitivity reactions to iodinated contrast media are rare. We recommend that patients with delayed exanthematous reactions undergo patch or intradermal tests with different contrast media and their additives, and that readings be performed immediately and later at days 2 and 3.

[Bisexuality and AIDS. Implications for heterosexual HIV infections in women].

One of the possible pathways into heterosexual population is the transfer of HIV-virus from bisexual men to their female partners. Therefore sexual behaviour of HIV-positive and -negative bisexual men (n = 31) before and after Aids-disease was analysed. Prior to the Aids-epidemic promiscuous behavior towards male partners (about one female partner per year versus 10 male partners per year). Relatively common contacts to woman occurred within steady relationships. After contact with HIV-test and personal counselling sexual practice became significantly different. The number of female and male contacts was markedly reduced, especially female chance acquaintances were avoided; safer sex was preferred and readiness to inform female partners about bisexuality was increased. This study suggests that reduction of risk for HIV-infection of female partners by homosexual men can be achieved by means of a HIV-test and personal counselling, a possibility that should be considered in preventive concepts.
