Observational Study
A clinicopathological study of upper aerodigestive tract cancers.
The upper aerodigestive tract (UAT) includes the nose and paranasal sinuses, oral cavity, pharynx, larynx, and salivary glands. Cancers of the UAT constitute approximately 4% of all malignancies. In this study, the varied nature of the UAT cancers was studied to find out their incidence, etiology, and clinicopathological correlations. ⋯ Studies are essential for education and awareness aimed at reducing exposure to habit-forming substances.

The aim of this study was to evaluate the effect of intracanal separated instruments with different lenghts on periapical pH levels using calcium hydroxide (CH) as an intracanal medicament. ⋯ Separated instrument may affect the rise in periapical pH level when using CH as the intracanal dressing. Therefore, 4 mm of separated instrument in the apical third showed a significant effect.

Septoplasty is one of the frequently applied nasal surgical procedures. There is still no gold standart objective method to evaluate the patients whom suffers from nasal blockage. To evaluate the septoplasty candidate with a Paranasal Computerised Tomography (PNCT) is one of the most discussed topic in the otorhinolaryngology surgical philosophy. ⋯ The sectional areas of nasal tomography images may show different values. However, it is still difficult to say that the clinical application of tomography images could be used as one of the indication criteria for the septoplasty procedure.

Case Reports
Management of ocular dystopia and lacrimal pathway obstruction in old multiple midfacial fractures: Case report.
Midfacial fracture is discontinuity of the bone affect maxilla, palate, zygomatico-maxillary complex, nasal bones, orbits, nasal-orbital-ethmoid complex, and frontal sinus. Delayed treatment can lead to malunion or nonunion bone. A 28 years old man presented with epiphora of the left eye and upgaze diplopia. ⋯ He underwent osteotomy and fixation with plate and screw, orbital floor reconstruction with silicone block implant, external dacryocystorhinostomy with silicone tube insertion procedure. In delayed treated malunion of midfacial fracture, fixation with plate and screw after refracture using an osteotome and orbital floor reconstruction with silicone block can be a good option for restoring normal anatomy. External dacryocystorhinostomy with silicone tube insertion is an effective treatment for post traumatic nasolacrimal duct obstruction.

One of the most common neurodevelopmental problems affecting behavior of children all over the world is attention deficit hyperactivity disorder (ADHD). Studies on ADHD prevalence in Africa used either parents' or teachers' disruptive behavioral disorder rating scale (DBDRS) to diagnose ADHD, but this study diagnose ADHD using both parents and teachers DBDRS simultaneously among primary school pupils in Ile-Ife. ⋯ ADHD prevalence of 4.7% was found among the children in Ile-Ife. Assessment of children for ADHD was done by parents at home and teachers in the school with DBDRS. The inattentive subtype was the most common and the hyperactive subtype was the least seen in the study. Early diagnosis and treatment of this disorder will bring better outcome in the children.
