BACKGROUND: Incidental findings on neuroimaging in the pediatric population are an emerging treatment challenge. Treatment options for these incidental childhood brain mass lesions, which radiologically may be assumed to be low-grade gliomas (LGG), vary, ranging from careful conservative "wait and scan" treatment to surgical biopsy, gross total resection, and upfront radiation and/or chemotherapy. As malignant transformation of LGG in children is extremely rare, some series advocate careful conservative management of these lesions; however, universal treatment protocols are not totally agreed upon...

BACKGROUND: Intracranial complications (ICC) of chronic suppurative otitis media (CSOM) occur even in the antibiotic area. These complications are commonly seen in pediatric patients due to poor hygiene and low immunity. They are more prevalent in developing countries due to illiteracy, low socioeconomic status and lack of access to health care facilities. OBJECTIVE: To study the incidence, clinical profile, treatment and outcome of pediatric patients presenting with intracranial complications of chronic suppurative otitis media...

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: Diffuse intrinsic pontine gliomas (DIPGs) have a dismal prognosis. Previously, diagnosis was based on a typical clinical presentation and magnetic resonance imaging findings. After the start of the era of biopsies, DIPGs bearing H3 K27 mutations have been reclassified into a novel entity, diffuse midline glioma, based on the presence of this molecular alteration. However, it is not well established how clinically diagnosed DIPG overlap with H3 K27-mutated diffuse midline gliomas, and whether rare long-term survivors also belong to this group...

M Burhan Janjua, Caitlin E Hoffman, Mark M Souweidane
The management of hydrocephalus can be challenging even in expert hands. Due to acute presentation, recurrence, accompanying complications, the need for urgent diagnosis; a robust management plan is an absolute necessity. We devised a novel time efficient surveillance strategy during emergency, and clinic follow up settings which has never been described in the literature. We searched all articles embracing management/surveillance protocol on pediatric hydrocephalus utilizing the terms "hydrocephalus follow up" or "surveillance protocol after hydrocephalus treatment"...

To determine a more precise and reliable method between Greulich-Pyle (GP) and MacKay's (MK) method for the determination of skeletal age in an Indian pediatric population. We carried out a cross sectional study for the assessment of skeletal age on the basis of examination of hand and wrist radiographs of 106 patients (1-15 years of age) who presented with soft tissue injury to hand by the GP and the MK method. These radiographs were evaluated by a radiologist and an orthopedic surgeon independently. In girls, the mean age difference between chronological and skeletal age was 8 months by the GP method, whereas it was 17 months by MK method...
