Reverse shoulder arthroplasty (RSA) is used commonly for a wide range of indications. The complications after the total shoulder replacements have been reported to be related with the prosthesis design. The type of the humeral stem is a consideration to reduce complication. Radiographic changes are seen at a high rate with new-generation press-fit stems. ⋯ The increased radiographic stress shielding adaptation leading to humeral osteolysis was found to have a negative effect on the functional results with the press-fit technique irrespective of stem design.

Silver diamine fluoride (SDF) is employed in caries prevention and treatment; however, tooth discoloration post treatment is a significant disadvantage, which can be reduced using glutathione (GSH), a water soluble tripeptide. ⋯ The use of GSH along with SDF helps in reducing the discoloration without compromising the shear bond strength.

The middle meningeal artery (MMA) is the leading supplier of the cranial dura and serves as a donor blood channel in craniotomy and cerebrovascular bypass procedures. However, the complex embryology of the MMA and population differences give rise to several anatomic variations that are of great importance in head injuries pertaining to the petrous and squamous parts of the temporal bone. Similarly, care must be taken to protect the artery during surgical operations that involve the maxillary artery and the vidian nerve. ⋯ The longer PB and the larger angle of the MMA in males could be attributed to why there is a high incidence of chronic subdural hematomas and MMA aneurysms in males. The current study is the first to propose a possible explanation for the aforementioned findings with regard to the organization of the MMA.

Dermatofibrosarcoma protuberan is a locally aggressive tumor that can be challenging to manage if it becomes recurrent. The best attempt at achieving cure is the first surgery. ⋯ Multidisciplinary care offers good outcomes when reconstructive needs are catered for. In our resource-poor setting, it will be beneficial to have an adequate (more than 5 cm margin) excision margin followed by reconstruction of defects by surgeons with adequate training in management of the pathology and tissue reconstruction.

Comparative Study
Histopathological Comparison of Various Tongue Base Reduction Processes.
Tongue base reduction surgery is the only minimally invasive technique that can be performed under local anesthesia as an outpatient procedure, especially to treat obstructive sleep apnea caused by hypopharyngeal obstruction. Studies reported that various devices could be used for tongue base reduction, but comparisons of these methods are limited in the literature. Our study aimed to compare the histological effects of tongue base reduction methods performed with the Celon radiofrequency, monopolar cautery, Coblator, and Sutter devices on the tissue. ⋯ Although we observed that all the methods used were safe, the method that produced the most fibrosis and tissue reduction was the Sutter method.
