Tracheobronchial pediatric tumors are very rare and procedures like pneumonectomy are seldomly indicated due to the associated morbidity. If a surgical approach is considered, the ideal oncological technique would be the minimally invasive sleeve resection, allowing preservation of lung parenchyma (very important in pediatric patients). Here we present the first report of a thoracoscopic right upper tracheo-bronchial sleeve lobectomy in a pediatric patient. A 10-year-old female patient, who received multiple antibiotic treatments for recurrent pneumonia without improvement, was diagnosed with a right upper lobe (RUL) carcinoid tumor...

BACKGROUND: Faced with one of the lowest physician-to-population ratios in the world, the Government of Tanzania is urging its medical schools to train more physicians. The annual number of medical students admitted across the country rose from 55 in the 1990s to 1,680 approved places for the 2015/16 academic year. These escalating numbers strain existing faculty. OBJECTIVE: To describe the availability of faculty in medical schools in Tanzania. DESIGN: We identified faculty lists published on the Internet by five Tanzanian medical schools for the 2011/12 academic year and analyzed the appointment status, rank, discipline, and qualifications of faculty members...

BACKGROUND: Understanding and addressing treatment abandonment (TxA) is crucial for bridging the pediatric cancer survival gap between high-income (HIC) and low-and middle-income countries (LMC). In childhood cancer, TxA is defined as failure to start or complete curative cancer therapy and known to be a complex phenomenon. With rising interest on causes and consequences of TxA in LMC, this study aimed to establish the lay-of-the-land regarding determinants of TxA globally, perform and promote comparative research, and raise awareness on this subject...

The management of pediatric thoracic synovial sarcoma remains a matter of debate in clinical oncology, especially as regard to the local control of the disease. Surgery remains the gold standard, while the role and timing of radiotherapy is still controversial. We report a 14-year-old male, who has not received proper treatment at the time of diagnosis and initial management. Intensity-modulated irradiation was performed only at relapse, as a salvage treatment and, at 10-month follow-up, the young patient was free from relapse, without significant acute and subacute toxicity...

BACKGROUND: Pediatric low-grade gliomas (LGGs) account for approximately half of all pediatric central nervous system tumors. The low-grade gliomas' first line of treatment is gross total resection. However, when gross total resection is not possible, options for adjuvant therapy are limited. MRI-guided laser ablation (magnetic resonance-guided laser interstitial thermal therapy (MRgLITT)) offers a new option for treatment in selected cases. We present a description of the current MRgLITT technology and an exemplary case-series review of our experience in its use in LGGs...

INTRODUCTION: Pediatric low-grade tumors are found in roughly 1-3 % of patients with childhood epilepsy; seizures associated with these tumors are often medically refractory and often present a significant morbidity, greater than the presence of the tumor itself. DISCUSSION: The unique morbidity of the seizures often requires an epilepsy surgical approach over a standard oncologic resection to achieve a reduction in morbidity for the child. Multiple quality-of-life studies have shown that unless a patient is seizure-free, they remain disabled throughout their life; the best way to achieve this in our patient population is with a multidisciplinary team approach with treatment goals focusing primarily on the epilepsy...

PURPOSE: Pediatric low-grade gliomas (LGGs) are the most frequent solid tumor in childhood. Based on an increasing number of literature reports, maximal safe resection is recommended as the first line of treatment whenever possible. However, distinguishing tumor tissue from the surrounding normal brain is often challenging with infiltrating neoplasms, even with the assistance of intraoperative, microscopic and conventional neuronavigation systems. Therefore, any technique that enhances the detection and visualization of LGGs intraoperatively is certainly desirable...

INTRODUCTION: Brain mapping through a direct cortical and subcortical electrical stimulation during an awake craniotomy has gained an increasing popularity as a powerful tool to prevent neurological deficit while increasing extent of resection of hemispheric diffuse low-grade gliomas in adults. However, few case reports or very limited series of awake surgery in children are currently available in the literature. METHODS: In this paper, we review the oncological and functional differences between pediatric and adult populations, and the methodological specificities that may limit the use of awake mapping in pediatric low-grade glioma surgery...

BACKGROUND: Auditory complications are an adverse event of childhood cancer treatment, especially common in children treated with platinum chemotherapy or cranial radiation. Variation between diagnostic childhood cancer groups has rarely been studied, and we do not know if the burden of auditory complications has changed over the last decades. PROCEDURE: Within the Swiss Childhood Cancer Survivor Study, we sent a questionnaire to all survivors who were diagnosed at age 16 years or less between 1976 and 2005...

OBJECTIVE: To report three cases of embryonal rhabdomyosarcoma (ERMS) of the cervix in young women successfully treated with fertility-sparing surgery and chemotherapy. METHODS: Between January 2014 and December 2015, three cases of ERMS of the cervix were confirmed in young women at a single tertiary cancer center. All cases were managed by a pediatric oncologist and a gynecologic oncologist with a combination of surgery and chemotherapy. Fertility-sparing surgeries (cervical conization or robotic-assisted radical trachelectomy) were offered to patients depending on the tumor size...

Outside the neonatal period, most platelets that are transfused to pediatric patients are given to those who are thrombocytopenic secondary to malignancy and associated therapy and/or hematopoietic progenitor cell transplant, or to those with significant bleeding associated with surgery, especially cardiac surgery. Indications for platelet transfusion, doses, and other practices for children largely mimic adult platelet transfusion protocols because there are few pediatric-specific studies in this area. Pediatric platelet transfusion practices would benefit from focused pediatric research...

Malignant germ cell tumors (GCT) arise from abnormal migration of primordial germ cells and are histologically identical whether they occur inside or outside the central nervous system (CNS). However, the treatment strategy for GCTs varies greatly depending on the location of the tumor. These differences are in part due to the increased morbidity of surgery in the CNS but may also reflect differential sensitivity of the tumors to chemotherapy and radiation therapy (RT) or not-yet-understood biologic differences between these tumors...

Head and neck reconstruction in pediatric oncology, even if it is based on adult experience, presents important characteristics including age-related growth, the type of tumor and donor sites features. Indications of free flaps are rare but required care that should be codified, taking into account the details specific to context, and not giving place for improvisation as it is important that surgical outcomes must be as simple as possible. The objective of this article is not to present the technical details of free flaps harvesting in children because it is what is certainly the least different with adults...

INTRODUCTION: The selection of a medical specialty has been associated with multiple factors, such as personal preferences, academic exposure, motivational factors and sociodemographic factors, such as gender. The number of women in the medical field has increased in recent years. In Latin America, we have not found any studies that explore this relationship. OBJECTIVE: To determine whether there is an association between gender and the intention to choose a medical specialty in medical students from 11 countries in Latin America...

Background We demonstrated recently that the implementation of a nurse-driven analgesia and sedation protocol (pediatric analgesia and sedation protocol [pASP]) for mechanically ventilated nonpostsurgical patients reduces the total dose of benzodiazepines and the withdrawal symptoms significantly. It has not been investigated if these results can also be expected in the group of patients undergoing surgery. Objectives To evaluate the effects of the pASP in mechanically ventilated postsurgical children regarding drug dosage, duration of mechanical ventilation, length of stay, and rate of withdrawal symptoms...
