The occurrence of yeasts on ripe fruits and frozen pulps of pitanga (Eugenia uniflora L), mangaba (Hancornia speciosa Gom.), umbu (Spondias tuberosa Avr. Cam.), and acerola (Malpighia glaba L) was verified. The incidence of proteolytic, pectinolytic, and mycocinogenic yeasts on these communities was also determined. A total of 480 colonies was isolated and grouped in 405 different strains. These corresponded to 42 ascomycetous and 28 basidiomycetous species. Candida sorbosivorans, Pseudozyma antarctica, C. spandovensis-like, C. spandovensis, Kloeckera apis, C. parapsilosis, Rhodotorula graminis, Kluyveromyces marxianus, Cryptococcus laurentii, Metchnikowia sp (isolated only from pitanga ripe fruits), Issatchenkia occidentalis and C. krusei (isolated only from mangaba frozen pulps), were the most frequent species. The yeast communities from pitanga ripe fruits exhibited the highest frequency of species, followed by communities from acerola ripe fruits and mangaba frozen pulps. Yeast communities from frozen pulp and ripe fruits of umbu had the lowest number of species. Except the yeasts from pitanga, yeast communities from frozen pulp exhibited higher number of yeasts than ripe fruit communities. Mycocinogenic yeasts were found in all of the substrates studied except in communities from umbu ripe fruits and pitanga frozen pulps. Most of the yeasts found to produce mycocins were basidiomycetes and included P. antarctica, Cryptococcus albidus, C. bhutanensis-like, R. graminis and R. mucilaginosa-like from pitanga ripe fruits as well as black yeasts from pitanga and acerola ripe fruits. The umbu frozen pulps community had the highest frequency of proteolytic species. Yeasts able to hydrolyse casein at pH 5.0 represented 38.5% of the species isolated. Thirty-seven percent of yeast isolates were able to hydrolyse casein at pH 7.0. Pectinolytic yeasts were found in all of the communities studied, excepted for those of umbu frozen pulps. The highest frequency of pectinolytic activity was found in mangaba frozen pulp communities. Around 30% of all isolates produced pectinases. The ability to split arbutin was observed in all communities ranging from 8% in yeasts from pitanga frozen pulps to 40.6% in acerola ripe fruit communities. Among 432 species tested, 125 were active for beta-glucosidase production, and Kloeckera apis, P. antarctica, C. sorbosivorans, and C. spandovensis-like were the most active species.

New classifications and availability of modern radiologic diagnostic tools have not only allowed a precise distinction between vascular tumors and vascular malformations but have also significantly modified management and treatment of these vascular anomalies. Hemangioma of infancy, the most common vascular tumor of this age and subject of this review, is approached from its clinical and laboratory features, differential diagnosis and therapeutic options. Although non-intervention remains the treatment of choice for the majority of cases, critical judgement is mandatory to decide whether other therapeutic modalities should be used.

Epidermolysis bullosa acquisita (EBA) is a subepidermal autoimmune blistering disease that is rarely reported in childhood. We describe a nine‐month‐old mulatto boy presenting with multiple, annular, widespread, tense blisters and oral lesions. The diagnosis of EBA was confirmed by histopathology, immunofluorescence, and immunoblotting analysis. The patient was successfully treated with systemic steroids (prednisone) and dapsone. After 20 months of initial treatment, clinical remission was observed, and dapsone remains as the current treatment. This case report emphasizes the rarity of EBA in childhood and the difficulties in reaching the final diagnosis.

BACKGROUND: vitiligo affects 0.5 to 4% of the world population. Twenty-five per cent of cases have their onset before the age of 10 years. Although the condition is prevalent in childhood, there are few epidemiological reports in children in the Brazilian literature. OBJECTIVE: to evaluate clinical and epidemiologic characteristics of vitiligo in childhood. METHODS: a descriptive study was performed in 73 children with vitiligo seen at the Pediatric Dermatology Outpatient Clinics of the Hospital das Clinicas- Universage Federal de Minas Gerais. The variables sex, age of onset of disease and treatment, affected body surface area, clinical type, site, autoimmune disease association, family history of vitiligo and initial treatment were evaluated. The statistical analysis was performed using simple frequency and means were compared through analysis of variance. RESULTS: Females accounted for 60.3% of the sample. The mean age at onset of disease was 5.7 years and the mean age at onset of treatment was 7 years. The body surface area affected was smaller than 1% in 71.8% and the localized type was detected in 76.7%. The most common site affected was the head. Family history of vitiligo was observed in 30.1% of patients. Hypothyroidism was found in one patient and 11% reported autoimmune diseases in their families. The initial treatment was topical steroids in the majority of patients. CONCLUSIONS: the findings of vitiligo in childhood in this study are basically similar to those reported in other countries.

OBJECTIVE To evaluate the incidence of Hib meningitis before and after the implementation of a vaccination program in the state of Rio Grande do Sul State, southern Brazil, in 1999. METHODS This retrospective study summarizes all data concerning Hib meningitis recorded by the state of Rio Grande do Sul Department of Health/Acute Communicable Disease Surveillance Agency between 1995 and 2001. All data were analyzed using the chi-square test (statistical significance: p < 0.005). RESULTS The decline in the number of cases of Hib meningitis was associated with the Hib vaccine coverage in children. From 1995 to 2001 the incidence of Hib meningitis decreased 89% (from 1.35 cases/100,000 people in 1995 to 0.15 cases/100,000 in 2001 (p < 0.01), especially in children younger than 1 year (p < 0.005). In the same period, Hib meningitis lethality decreased from 17.8 to 6.7 % (p < 0.01). CONCLUSIONS The implementation of an Hib meningitis vaccination program has nearly eliminated Hib meningitis in the state of Rio Grande do Sul. These findings underscore the need to maintain the vaccination in children, with a thorough investigation of suspected cases and reporting of confirmed cases.

Dyskeratosis congenita is an inherited disease characterised by the triad of abnormal skin pigmentation, nail dystrophy and mucosal leukoplakia. Non-cutaneous abnormalities (dental, gastrointestinal, genitourinary, neurological, ophthalmic, pulmonary and skeletal) have also been reported. Bone marrow failure is the main cause of early mortality, with an additional predisposition to malignancy. Men are more affected than women and X-linked recessive, autosomal dominant and autosomal recessive forms of the disease are recognised. We report a case of a male child who presented the classic triad of lesions, without familial cases. A review of the literature is also made, emphasizing the importance of a multidisciplinary approach, which is fundamental for an early diagnosis of the complications.

OBJECTIVE The authors describe a case of giant hemangioma treated with interferon alpha-2a and review the role of this drug and other therapeutic modalities in the management of vascular lesions. METHODS A seven month-old child with giant hemangioma and persistent bleeding, anemia and repeated infections was treated with interferon alpha-2a. The drug was administered at the dosage of 3 million units/m(2)/day, subcutaneously, for nine months. RESULTS Response to treatment was considered excellent, with regression of 90% of the lesion, control of bleeding, infection and anemia, and catch-up growth. No untoward effects were observed. CONCLUSION Interferon alpha-2a should be considered as a valid therapeutic option in selected cases of hemangioma in children.
