This study aimed to examine the microleakage of class V cavities of primary molars prepared by either a conventional dental bur or Er:YAG laser and one of two different adhesive systems. ⋯ Self-etch bonding systems and cavity preparation with Er:YAG laser may be an alternative to conventional restoration of primary molars with compomers. Further studies are warranted to fully elucidate the effect of laser-based etching techniques in cavities prepared by laser.

Acquired metallo-β-lactamases (MBLs) pose serious problem both in terms of treatment and infection control in the hospitals and report across the world showed an increase in their prevalence. However, there is a paucity of data from Africa, and their report is rare in Nigeria. ⋯ The prevalence of MBL-producing strains of P. aeruginosa which poses serious challenge for therapeutics and infection control is currently low in Abuja, North Central, Nigeria. Therefore, rational use of the carbapenems and other antipseudomonal antibiotics, regular surveillance and adequate infection control measures should be instituted to limit further spread.

The aim of this study was to evaluate the crown and root development in patients with cleft lip and palate using medical software programmes. ⋯ In particular, among patients with cleft lip and palate, on obtaining a solid model of the tooth structure by using these programs, tooth development can be examined in more detail, diagnosis can be made more reliable, as well as in treatment planning. We believe that these programs can be used to resolve certain limitations such as a lack of an application to be used in routine dental treatment and in particular the need to do more study.

Pleural effusion is a common clinical problem with management difficulties. The aim of this study is to evaluate vascular endothelial growth factor (VEGF) in differential diagnosis of pleural effusions and the presence of correlation between radiological features and biochemical properties. ⋯ The overlap of pleural VEGF levels between the groups may limit the value of VEGF in discriminating between malignant versus benign and exudative versus transudative effusions; however, it may be a useful adjunct to various methods. The VEGF levels in pleural fluid seem to be related to the degree of inflammation and pleural invasion.

Randomized Controlled Trial
Gabapentin pretreatment for propofol and rocuronium injection pain: A randomized, double-blind, placebo-controlled study.
This prospectively-planned, randomized, double-blind and placebo-controlled study aims to evaluate the effect of 1200 mg gabapentin premedication on the incidence and severity of propofol and rocuronium injection pain. ⋯ Premedication with 1200 mg gabapentin 2 hours before propofol and rocuronium injection reduced the incidence and severity of injection pain.
