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.

Children with Down syndrome (DS) are at increased risk for obstructive sleep apnea (OSA) compared with children without DS, with reported prevalence of 31 ± 75% among clinical-based samples. We aimed to find out whether there is any effect of OSA on periodontal and dental health in children with DS. ⋯ OSA is an important problem for DS and may affect oral health negatively. Based on our findings, OSA can be associated with impaired gingival health in DS children and close follow-up may be necessary for this group.

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.

Randomized Controlled Trial
Potential effects of advanced platelet rich fibrin as a wound-healing accelerator in the management of alveolar osteitis: A randomized clinical trial.
The aim of the present study was to determine whether the use of advanced platelet rich fibrin based on the low speed+ centrifugation concept (A-PRF+) might improve the pain management and healing of delayed wound healing among cases of alveolar osteitis following mandibular third molar extraction. ⋯ The results show that A-PRF+ might represent an improved and accelerating therapeutic development for hard and soft tissue healing in management of alveolar osteitis that is also effective in reducing pain.

Comparative Study
Prolonged air leak after video-assisted thoracoscopic surgery in patients with primary spontaneous pneumothorax.
Patients who have undergone a lung resection owing to primary spontaneous pneumothorax (PSP) may develop prolonged air leak (PAL) during the postoperative period. The present study investigates potential risk factors associated with postoperative PAL in patients who were operated on for PSP. ⋯ PAL is the most common complication associated with PSP surgeries. Although several factors may affect PAL development, no definite conclusion could be drawn concerning the investigated risk factors. We believe that similar studies may contribute to the care of this rare patient population.
