Background: Nevoid basal cell carcinoma syndrome (NBCCS) is a neurocutaneous disease, characterized by tumorigenesis and developmental anomalies due to aberrant sonic hedgehog (Shh) signaling. Patients with NBCCS typically appear calm and carefree, suggesting that a specific personality in these patients may be associated with an enhanced hedgehog pathway. Our study aimed to determine the personality type in these patients., Methods: We enrolled 14 mentally normal patients with genetically confirmed NBCCS (seven males and seven females; mean age = 25.2 years) and 20 controls (10 males and 10 females; mean age = 27.9 years). The patients were assessed with the Japanese version of the Temperament and Character Inventory, based on the seven-dimensional model of temperament and character, and their clinical symptoms were evaluated. The amygdala volumes of six patients with NBCCS were measured using magnetic resonance imaging with image-processing software., Results: Patients with NBCCS scored significantly lower on harm avoidance (0.89) than controls (1.00; P = 0.0084). Moreover, patients with NBCCS and developmental malformations such as rib anomalies, who may have experienced Shh signaling enhancement from the prenatal period, scored significantly lower on harm avoidance (0.80 [P = 0.0031]). The left amygdala volume was also significantly reduced in patients with NBCCS (P = 0.0426)., Conclusions: Patients with NBCCS who experienced increased Shh signaling from the prenatal period showed significantly lower harm avoidance related to serotonin. The left amygdala volume was significantly reduced in these patients. Our results indicate that Shh signaling may influence the human personality., (© 2020 Japan Pediatric Society.)

Langerhans cell histiocytosis (LCH) is a rare proliferative disease accompanied by the accumulation of pathological Langerhans cells, which often spreads into multi-site and multi-organ systems. We here describe a girl with a history of Kawasaki disease and cervical lymphadenopathy who presented with occipital LCH. Adrenal tumor was detected on staging evaluation of LCH and was diagnosed as neuroblastoma on resection using laparoscopic surgery. Neither tumor relapsed following chemotherapy for LCH and resection of neuroblastoma. Although LCH often spreads into multi-organ lesions, invasive biopsy may be needed for tumors with atypical localization for LCH in consideration of the synchronous occurrence of malignancies., (© 2014 Japan Pediatric Society.)

Background: The aim of the present study was to investigate the efficacy of i.v. immune globulin (IVIG) therapy combined with corticosteroids for additional treatment of acute Kawasaki disease (KD) unresponsive to initial IVIG treatment., Methods: In 50 prospective KD patients, six IVIG non-responders without clinical improvement within 24-48 h after completion of initial IVIG, received 2 g/kg IVIG concurrently with 2 mg/kg i.v. prednisolone sodium succinate (PSL) until normalization of C-reactive protein level. Treatment was then changed to oral PSL, which was tapered over time. Clinical and coronary artery lesion (CAL) outcomes were compared with those of 13 IVIG non-responders who received additional heterogeneous therapies in 125 retrospective KD patients. In addition, the scoring system of Kobayashi et al. for prediction of non-responsiveness to initial IVIG treatment was retrospectively verified in 175 KD subjects, consisting of 50 prospective and 125 retrospective patients in order to evaluate the efficacy of the re-treatment regimen., Results: Incidence of CAL in the study patients was lower than in the control patients, although differences were not significant both in the acute stage (within 1 month: 1/6, 16.7% vs 7/13, 53.8%; P= 0.177) and in the convalescent stage (after 1 month: 0/6, 0.0% vs 4/13, 30.8%; P= 0.255). According to the non-responder prediction system, the scores of six study and 13 control patients before initial IVIG treatment were similar (7.2 ± 1.9 vs 5.3 ± 3.1; P= 0.200). No serious adverse effects related to each treatment were noted in patients of either group., Conclusions: Additional IVIG combined with concurrent PSL appears to be safe and worth evaluation for the treatment of acute KD unresponsive to initial IVIG treatment., (© 2011 The Authors.
