Obturator hernia (OH) is a relatively rare pelvic hernia. OH is usually seen in elderly, multiparous females and patients with a low body weight. Obturator hernia accounts for 0.07-0.4% of all intraabdominal hernias and 0.2-5.8% of small bowel hernias. ⋯ Segmental resection and anastomosis was performed. Early diagnosis and surgical intervention are essential. This demonstrates that emergency CT scan is useful for the diagnosis of obturator hernia in patients presenting with mechanical intestinal obstruction of unknown origin.

The purpose of this study was to assess the quantity of the chelated calcium ions and the smear layer removal efficiency after root canal final irrigation with three different solutions. ⋯ The application time of the chelators' solutions must not exceed 5 min to completely remove smear layer, and 0.2% chitosan is a natural substitute for 17% EDTA with a safety application for 24 h.

Multiple symmetric lipomatosis (MSL) is a very uncommon disease. Its etiopathogenesis is uncertain, although it has been linked to a variety of factors. Its main characteristic is the overgrowth of fat in form of an unencapsulated lesion. ⋯ A clinical diagnosis of gynecomastia was initially made. Partial mastectomy was done and MSL was reported on histopathologic examination. Our literature search revealed no previous case of MSL in the breast reported from our environment.

The prevalence of white spot lesions/tooth demineralization during orthodontic fixed appliance therapy ranges widely from 2 to 96% of patients. The purpose of this study was to evaluate measures used by orthodontists practicing in Nigeria to manage demineralization during and after fixed orthodontic treatment and how it compares with the available evidence-based information. ⋯ The demineralization preventive measures used by Nigerian orthodontists and orthodontic residents are inconsistent and not based on evidence-based information. The development of standardized demineralization prevention protocol was therefore recommended.

Prognosis and risk factors of nerve injuries in displaced pediatric supracondylar humerus fractures.
Supracondylar humerus (SCH) fractures are serious injuries due to the neighborhood of critical neural and vascular structures. One of the most devastating complications of SCH fractures is neurological damage, since it may cause permanent disability. The aim of this study is to categorize neurological complications, to report long-term functional outcomes, and to determine risk factors associated with childhood SCH fractures. ⋯ The prognosis of these nerve injuries is excellent, especially the iatrogenic ones. A long and sharp bone fragment (spike) may be responsible for nerve injuries in some children. Surgical exploration is not necessary after an iatrogenic nerve injury when there is no neurotmesis. Patience and care are utmost needed to handle neurological complications.
