RESUMO
Vaginal bleeding can occur shortly after delivery in 3%-5% of newborns as a consequence of placental hormone withdrawal . Although usually benign, its differential diagnosis includes central precocious puberty, tumours and other pathological conditions. A girl born at 26 weeks of gestation presented with five episodes of vaginal bleeding, each lasting less than a week, initiated at 4 months of age. Luteinising hormone and oestradiol levels were in the pubertal range. Later, she exhibited breast development, with no other pubertal signs. An ultrasonography test revealed an impregnated endometrium and a right ovarian cyst with 43 mm of diameter. A cranioencephalic MRI was unremarkable. Clinicians adopted expectant management and there was clinical, hormonal and radiological resolution in 3 months. The spontaneous resolution suggested mini-puberty of infancy. This is usually an asymptomatic condition, but to date, four cases of an exacerbated form in extremepremature infants have been reported. Long-term follow-up data are missing.A girl born at 26 weeks of gestation presented with five episodes of vaginal bleeding, each lasting less than a week, initiated at 4 months of age.

Non-typhoidal Salmonella osteomyelitis in healthy children is a very rare condition. A previously healthy 7-year-old boy presented with foot pain following a small injury. Local inflammatory signs of the foot were observed, with a normal radiograph. Two weeks before, he had had gastroenteritis. Assuming cellulitis, flucloxacillin was began. Early during admission, surgical subcutaneous abscess drainage was performed and Salmonella enteritidis was identified. According to bacterial susceptibility, antibiotherapy was changed to ceftriaxone. A foot radiograph and an MRI scan, performed on the 9th and the 12th days, revealed findings suggestive of osteomyelitis of the metaphysis of the fifth metatarsal. Clinical worsening persisted and surgical extensive debridement was needed. A 6-week antibiotic treatment was completed, with a good outcome. Osteomyelitis with a poor evolution in children with risk factors (prior gastrointestinal illness, warm weather and previous exposure to antibiotics) can raise the possibility of a non-typhoidal Salmonella infection.

Lipschütz ulcers (LU) are non-sexually related genital ulcers, rarely reported. We describe a healthy 11-year-old girl, who presented with fever and a painful vulvar ulcer associated with erythematous tonsillitis. Throat swab test for Group A Streptococcus (GAS) was positive. She was treated with amoxicillin. Further investigation was negative, including Herpes Simplex virus DNA from ulcer swab and serology for Epstein-Barr virus, cytomegalovirus and Mycoplasma pneumoniae Antistreptolysin O titre was high. The ulcer healed in 2 weeks, with no recurrence in a 1 year follow-up period. The association of LU with GAS tonsillitis is very rare.
