RESUMEN
In recent years, some cases of central precocious puberty (CPP) have been reported in patients with autism spectrum disorder (ASD). Here, we report CPP in two girls with ASD. The first case was a girl, 7 years and 9 months of age. Breast budding was observed at 7 years and 2 months and pubic hair at 7 years and 8 months of age. She was diagnosed with CPP based on guidelines and ASD according to her developmental history. Considering the psychosocial burden caused by the discrepancy between her cognitive and behavioral development and the progression of secondary sex characteristics, gonadotropin-releasing hormone (GnRH) analog therapy was initiated. Case 2 was a girl, 9 years and 8 months of age. She was diagnosed with ASD according to her developmental history. Treatment using oral aripiprazole for hypersensitivity to touch and taste had been initiated, with the onset of menarche at 9 years and 10 months of age. Breast budding had been observed before 7 years and 6 months old. She was diagnosed with CPP based on guidelines. Considering that menarche was not a significant psychosocial burden and the difficulty for her and her family to attend regular follow-ups, GnRH analog therapy was not initiated. Although the pathophysiological pathway linking ASD and CPP remains to be elucidated clinically, attention to CPP in ASD is needed, considering the increase in reported cases. In addition, the indication of GnRH analog therapy should be judged considering the psychosocial burden associated with secondary sexual characteristics.
RESUMEN
In this case report, we describe the case of an infant with repeated wheezing diagnosed relatively early with congenital tracheal and bronchial stenosis after evaluation by chest three-dimensional computed tomography (3D-CT). The patient was a six-month-old male infant with a one-month history of cough and wheezing. His symptoms worsened the day before admission, and he was admitted with pneumonia and wheezing. However, wheezing continued after treatment with intravenous steroids and inhalation of a short-acting ß2-stimulant. 3D-CT of the chest revealed tracheal stenosis, right bronchial stenosis, and right tracheobronchial bronchus. The patient was finally diagnosed with congenital tracheal and bronchial stenosis via bronchoscopy. A virtual bronchoscopic navigation image of the tracheal lumen was created based on the CT images. Although virtual bronchoscopic navigation is more difficult for the dynamic evaluation and evaluation of mucosal lesions than bronchoscopy, it has the advantage of not directly invading the airway. Therefore, if a fixed stenotic lesion is suspected at a facility where bronchoscopy is difficult, evaluation using chest 3D-CT and virtual bronchoscopic navigation may be helpful for diagnosis. In conclusion, congenital tracheal/bronchial stenosis should be considered in patients with prolonged wheezing and recurrent airway infections, and evaluation by chest 3D-CT and virtual bronchoscopic navigation may be helpful for diagnosis.
RESUMEN
Pyomyositis is a rare, subacute, deep bacterial infection of the skeletal muscle. When treatment is delayed, pyomyositis causes abscess formation and progresses to sepsis; therefore, its early diagnosis is important. However, the clinical presentation and laboratory findings of pyomyositis are not specific; hence, diagnosis often takes time. We encountered the case of a girl with obturator pyomyositis and redness and swelling of the labium majus, which we considered as potentially important symptoms for distinguishing obturator pyomyositis from septic hip arthritis. An 8-year-old Japanese girl presented to our hospital with fever and right hip pain. On physical examination, she had redness and swelling of the right labium majus and a right limp. She was diagnosed with obturator pyomyositis and labium majus cellulitis with magnetic resonance imaging. Her clinical presentation markedly improved after starting antibiotic therapy with intravenous cefazolin for 2 weeks and oral cefaclor for 1 week. Improvement in the inflammation of the obturator muscle and labium majus was confirmed with follow-up magnetic resonance imaging. She recovered fully with no long-term sequelae. In conclusion, obturator pyomyositis rather than septic hip arthritis should be considered in children with a limp and hip and perineal pain, particularly girls with redness and swelling of the labium majus. In addition, imaging studies, including magnetic resonance imaging, should be performed for early diagnosis.
