Objective: To report the first case of disseminated Trichosporon spp infection in a newborn infant in Brazil, discussing a few aspects concerning management and treatment. A new spectrum of pathogens associated with severe infections in neonatal ICU has arisen, afflicting mainly newborn infants weighing less than 1,000 g at birth. Infection with Trichosporon asahii is rare and often fatal in this group of patients. Description:A case of Trichosporon spp fatal infection in a newborn weighing 815 g at birth is reported. Literature search in the main databases returned only nine articles, reporting 14 cases of infection with this fungus in preterm newborns. Conclusions:The rate of invasive fungal infection is around 6% in this group of patients, Trichosporon infection being a likely occurrence. Mortality rate in these cases is extremely high, but early treatment with triazole antifungals improves prognosis significantly. ResumoObjetivo: Apresentar o primeiro caso de infecção disseminada por Trichosporon spp em um recém-nascido no Brasil, discutindo alguns aspectos de manejo e tratamento. Um novo espectro de agentes infecciosos associado a infecções graves em UTI neonatais tem surgido. Ele atinge particularmente recém-nascidos com peso de nascimento abaixo de 1.000 g. A infecção por Trichosporon asahii é rara e quase sempre fatal nesse grupo.Descrição: É apresentado o caso de um recém-nascido de 815 g com infecção fatal por Trichosporon spp. Na literatura pesquisada nos principais bancos de dados, apenas nove artigos foram encontrados, com descrição de 14 casos de infecção por esse fungo em recém-nascidos prematuros.Conclusões: A taxa de infecção fúngica invasiva é de cerca de 6% no grupo de risco referido acima, sendo a causada por Trichosporon uma possibilidade. A taxa de mortalidade desses casos é muito alta, mas o tratamento precoce com triazólicos melhora muito o seu prognóstico. J Pediatr (Rio J) IntroduçãoA prematuridade é um dos problemas mais relevantes da perinatologia moderna, sendo responsável por altas taxas de mortalidade e morbidade entre recém-nascidos sem anomalias congênitas. Nascimentos prematuros ocorrem em, aproximadamente, 11% das gestações e são responsáveis por 70% das mortes neonatais e 50% das sequelas neurológicas de origem neonatal, incluindo a paralisia cerebral 1 .A maior causa de mortalidade entre esses pequenos pacientes é a sepse e suas complicações. A suscetibilidade a infecções se deve a problemas relacionados com vários componentes da defesa orgânica e com o desequilíbrio da aquisição da microbiota endógena 1 .A infecção por fungos tem alta taxa de mortalidade, variando entre 10 e 28%, nos recém-nascidos que pesam menos de 1.000 g. Os agentes mais costumeiramente encontrados são a C. albicans, C. parapsilosis, C. tropicalis, C. lusitaniae e C. glabrata 1 .O Trichosporon asahii (antigamente conhecido como Trichosporon beigelii ou cutaneum) é uma causa incomum de sepse fúngica em recém-nascidos de muito baixo peso 2-10 .

Genital ambiguity is part of the disorders of sex development. Its prompt recognition and early and precise etiological investigation are fundamental to its proper management. A patient with ambiguous genitalia, born cesarean due to severe pre-eclampsia and oligohydramnios at 34 weeks and 2 days, 1505g, considered small for gestational age (SGA). Examination showed an 1.9cm falus, penoscrotal urethral meatus and bilaterally palpable gonads. In the investigation, he presented normal testosterone (T), androstenedione (A) and dihydrotestosterone (DHT); T/DHT ratio of 9.7 (<10) and T/A of 7.4 (>0.8) and karyotype 46,XY. It was decided for male sex assignment. Testosterone stimulus test was performed, showing penis enlargement of 1.5cm. Intrauterine growth restriction is a considerable risk factor for genital ambiguity in individuals 46,XY. This seems to be the etiology in this case, given its normal hormonal and cytogenetic evaluation and the response to the testosterone stimulus.
