[Infections due to herpes-varicella viruses in Hodgkin's disease (author's transl)].

The infections due to herpes-varicella viruses occurring in 191 patients with Hodgkin's disease form the basis of this report. There were overall 41 episodes (26.7%) in 40 patients, distributed as follows: varicella in three cases, atypical herpes-varicella in two cases, and herpes zoster in 36 cases, the latter showing systemic spread in seven instances, one to the central nervous system (myelitis) and six to the skin. The mortality was 2.5% of all infections, and 33% of the varicella cases. Morbidity was apparent as postherpetic neuralgia in seven patients (19.4%), postherpetic paraplegia in one case (2.5%), and severe thrombocytopenia in another case (2.5%). The statistical study of the factors contributing to the development of reactivation episodes demonstrated that neither age, sex, or previous splenectomy were influential. The results obtained in relation to the stage and histologic type of Hodgkin's disease can not be fully evaluated because of the artifact introduced by other variables such as type of therapy and observation time. There was a clear relationship with the aggressiveness of therapy, because 81.7% of the viral episodes occurred in patients submitted to total radiotherapy with or without chemotherapy, or with partial radiotherapy plus chemotherapy. In the patients with systemic spread there was a clear relationship with prior splenectomy (p less than 0.005). The clinical features of these patients are commented upon.

[Hipercalcemia and non-Hodgkin's lymphomas. Report of three patients (author's transl)].

Three out of 140 patients with non-hodgkin's lymphoma treated in a Department of Internal Medicine showed hypercalcemia during their clinical course. Hypercalcemia was symptomatic in two patients causing renal failure in one of them and a metabolic encephalopathy in the other. In the third case hypercalcemia was a casual finding. Serum calcium levels varied between 14.8 and 16.6 mg/100 ml; serum phosphate and tubular reabsorption of phosphate were normal. Alkaline phosphatase were high in the three cases. Bone disease was present in two cases. Transient responses were obtained with the administration of prednisone and calcitonin associated to forced diuresis. Indomethacin was ineffective. Pathogenesis of hypercalcemia could be related to the release of an osteoclastic activator factor. The role of prostaglandins and the presence of PTH-like mechanisms were discarded in our cases by indirect methods. The poor prognosis of patients with non-hogkin's lymphoma and hypercalcemia in stressed.

[Sensorineural hearing loss due to neonatal hyperbilirubinemia].

In this article, the sensorineural hearing loss is presented as a possible sequelae of neonatal hyperbilirubinemia. In our program of early hipoacusia detection, 241 babies were examined from January 1996 until November 1999; 7 cases had a history of hyperbilirubinemia in the neonatal period and 2 of them were diagnosed of sensorineural hearing loss. We discuss how the bilirubin or any other associated factor might have been the cause and this could explain the selective affectation of some children.

The associated microflora to the larvae of human bot fly Dermatobia hominis L. Jr. (Diptera: Cuterebridae) and its furuncular lesions in cattle.

The microflora associated to furuncular lesions, larvae and pupae of Dermatobia hominis, as well as the relationships between parasite, host and microflora associated, as a comprehensive microsystem, has been studied. One hundred and two furuncular myiasis due to D. hominis larvae in several breeds of cattle were studied and the following bacterial species were significant: Staphylococcus aureus, S. epidermidis, S. warneri, Bacillus subtilis and Escherichia coli. Closely related, the microflora associated to 141 samples from first, second, third instar larva and both external surface and larval cavities has been studied. The representative associated microflora to the larvae were: S. aureus, B. subtilis, S. hycus and Moraxella phenylpiruvica, Moerella wisconsiensis, Proteus mirabilis and P. vulgaris, M. phenylpiruvica, M. wisconsiensis, P. mirabilis and P. rettgeri were the representative microflora associated to 64 pupae of D. hominis.

[Study of mechanisms and factors related to sexual abuse in female children and adolescents]

OBJECTIVE: To study the frequency of sexual abuse in children and adolescents and its related factors. METHODS: Retrospective analysis of 617 cases of sexual abuse, assisted between July 1994 and August 1999 at the Womeńs Health Reference Center, divided into two groups: 71 children (age <10 years), and 546 adolescents (age > or =10 and <20 years). The analyzed variables were: sexual crime; embarrassment; presumption of violence; characteristics and number of abusers; the victimacute;s situation at the moment of the crime; and occurrence of physical traumas. Epi Info 6 software was utilized to gather data, and the results were analyzed by the chi-square test. RESULTS: Significant statistic results were found. 90.8% of the adolescents were victims of rape, and 46.5% of the children suffered sexual assault. The presupposed violence (PV) was more frequent in the group of children (63.4%) and a serious threat in the group of adolescents (63.2%). Innocentia consilli was exclusive PV among 100% of children and 59.5% of adolescents. 84.5% of children were molested by identifiable abusers, most frequently family members. Perpetrators were unknown in 72.3% of the cases of adolescent abuse. 42.3% of sexual abuse of children occurred in their homes, and 28.2% at the abusers. Adolescents were approached during daily activities (34.8%) and on their way to work or school (28.4%). Most patients did not have genital or extragenital trauma. CONCLUSIONS: Children suffered sexual assault, perpetrated by a known abuser through presupposed violence in private places. Adolescents were raped by unknown individuals, under serious threat, in nondomestic places.
