RESUMO

BACKGROUND: Aureobasidium melanigenum is a ubiquitous dematiaceous fungus that rarely causes invasive human infections. Here, we present a case of Aureobasidium melanigenum bloodstream infection in a 20-year-old man with long-term catheter use. CASE PRESENTATION: A 20-year-old man receiving home care with severe disabilities due to cerebral palsy and short bowel syndrome, resulting in long-term central venous catheter use, was referred to our hospital with a fever. After the detection of yeast-like cells in blood cultures on day 3, antifungal therapy was initiated. Two identification tests performed at a clinical microbiological laboratory showed different identification results: Aureobasidium pullulans from matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, and Cryptococcus albidus from a VITEK2 system. Therefore, we changed the antifungal drug to liposomal amphotericin B. The fungus was identified as A. melanigenum by DNA sequence-based analysis. The patient recovered with antifungal therapy and long-term catheter removal. CONCLUSION: It is difficult to correctly identify A. melanigenum by routine microbiological testing. Clinicians must pay attention to the process of identification of yeast-like cells and retain A. melanigenum in cases of refractory fungal infection.

RESUMO

PURPOSE: It is difficult to perform intestinal anastomosis in low-birth-weight infants because the intestinal diameter is small and the discrepancy in diameter of the proximal and distal intestines is often large, but there has been no optimal-sized training model. Therefore, we developed a new intestinal anastomosis training model that imitated the size of the intestine in low-birth-weight infants, and evaluated its face and construct validity. METHODS: Two intestinal models were developed with crossMedical, Inc. using a hydrophilic acrylic material (wet model) or a polyurethane soft resin (dry model). The inner diameter of the simulated intestinal tract was 15 mm on the oral end and 6 mm on the anal end. Thirteen pediatric surgeons performed anastomosis and responded to the questionnaire. RESULTS: In the questionnaire, the wet model had significantly higher scores than the dry model in "appearance", "softness" and "usefulness for training". In the anastomotic results of the wet model, the anastomosis leak pressure was significantly correlated with the number of intestinal anastomotic experiences in low-birth-weight infants (correlation coefficient = 0.64, P = 0.035). CONCLUSIONS: The wet-type intestinal anastomosis model showed good face validity. Its leak pressure had a significant correlation with clinical experience; thus, construct validity was demonstrated.

RESUMO

PURPOSE: Pneumothorax often develops in patients with Marfan syndrome (MFS). Here, we examined the effects of conservative and surgical pneumothorax treatments in children with MFS. METHODS: In this study, 23 patients, less than 20 years old, diagnosed with both MFS and pneumothorax between 1999 and 2019 were included. All data were collected retrospectively from patients' medical records. RESULTS: In total, 18 of 23 patients (78%) had relapsed pneumothorax either on the ipsilateral or contralateral side. Among these 18 patients, 6 (26%) patients had multiple relapses. Conservative and surgical treatments of pneumothorax were attempted in 33 and 29 lungs, respectively. The conservative treatment was attempted as a definitive therapy in 21 lungs. Twelve conservative treatments (57%) failed, which required surgical intervention. In 9 lungs (43%) with successful conservative treatment, 6 (67%) had ipsilateral relapses. In contrast to the above findings, only 4 (13%) ipsilateral relapses were observed in 29 surgical treatments. CONCLUSIONS: Our study revealed a low response and high relapse rate when MFS adolescents who diagnosed pneumothorax were subjected to the conservative treatment modality. Thus, we recommend surgical intervention as the first line of therapy to treat pneumothorax in adolescents diagnosed with MFS. LEVEL OF EVIDENCE: Ⅲ (Treatment Study).

RESUMO

PURPOSE: This study aimed to investigate the optimal indication and availability of prophylactic innominate artery transection (PIAT). METHODS: We retrospectively analyzed the medical records of the patients with neurological or neuromuscular disorders (NMDs) who underwent PIAT. Meanwhile, we originally defined the tracheal flatting ratio (TFR) and mediastinum-thoracic anteroposterior ratio (MTR) from preoperative chest computed tomography imaging and compared these parameters between non-PIAT and PIAT group. RESULTS: There were 13 patients who underwent PIAT. The median age was 22 years. PIAT was planned before in one, simultaneously in five, and after tracheostomy or laryngotracheal separation in seven patients. Image evaluations of the brain to assess circle of Willis were performed in all patients. Appropriate skin incisions with sternotomy to expose the innominate artery were made in four patients. All patients are still alive except one late death without any association with PIAT. No neurological complications occurred in any patients. As significant differences (p < 0.01) between two groups were observed for TFR and MTR, objective validity of the indication of PIAT was found. CONCLUSIONS: PIAT is safe and tolerable in case of innominate artery compression of the trachea with NMDs. TFR and MTR are useful objective indexes to judge the indication of PIAT.
