Dental implants have a broad array of applications, from single tooth replacement to complete oral rehabilitation with a prosthesis. Microorganisms colonize the implant's surface when it is exposed to the oral cavity. A successful implant treatment, however, is dependent on the absence of inflammation in the peri-implant tissues. The relationship of implant surface characteristics to the microbiota plays a major role in the success of an implant. The initial adherence of bacteria to intraoral surfaces is determined by the surface's physiochemical properties, such as the surface free energy (SFE) of the bacteria, the solid phase, and the surrounding liquid, as well as the surface integrity and composition of the solid medium. The surface characteristics at the micro or nanometer level, hydrophilicity, and biochemical bonding are responsible for implant success. The surface can be modified by either addition or subtraction procedures like acid etching, sandblasting, plasma spraying, hydroxyapatite coating, etc. By modifying the characteristics of the surface, biocompatibility can be improved, faster osseointegration can be provoked. The roughed surface has good osseointegration due to clot stability whereas, on the contrary, they are more prone to biofilm formation. Biofilm has been associated with almost all periodontal diseases, therefore knowledge of microbes around the implant is necessary for diagnosis and treatment. This review focuses on the influence of implant surface characteristics such as surface roughness, surface free energy, and surface composition on oral microbiota.
Split-skin grafts contain the entirety of the epidermis and a variable amount of dermis, depending on the thickness of the harvested graft. The process of skin grafting involves the creation of another wound at the donor site, which has to be managed as the donor-site wound, will be more painful due to exposure of sensory nerve endings and distressing to the patient compared with that of the recipient site.
In spite of various advances in techniques of grafting, management of the donor site is more or less standard. Donor site should also be managed adequately to avoid complications and promote wound healing. Various methods have been used by practitioners for the management of donor site.

Spinal anesthesia is a preferable anesthesia technique for various abdominal and below abdominal surgeries. There are different local anesthetics available for spinal anesthesia. By choosing the recently available isobaric ropivacaine, making it hyperbaric by addition of dextrose with the right choice of adjuvant, which is devoid of undesirable effects, must provide better analgesia and early cessation of motor blockade. The myth and controversies involving the usage of drugs intrathecally for daycare surgeries, their advantages, disadvantages, and indication of each adjuvant along with doses are discussed in this review.

Selvarajah A, Sivarajan AA, Naik SS. Effectiveness of Magnetic Resonance Imaging in Comparison to Electroencephalography in Newly Diagnosed Seizure Patients. 2022; 11 (1):13-15.
In newly diagnosed seizure patients though the norm is to do an electroencephalogram (EEG), underlying structural abnormalities will be better depicted on magnetic resonance imaging (MRI), and EEG may turn out to be normal. Since a wide variety of structural abnormalities in the brain can lead to seizures, studies had shown that MRI was more effective in detecting lesions accurately in addition to an EEG, so it is better to include MRI as a first line of investigation in seizure patients for early detection, treatment, and better prognosis of underlying structural abnormality.
Background: Creative thinking is considered as an ultimate form of human thinking, which is influenced by various biological and psychological factors. Literature reveals that bodily movements are associated with enhanced creativity in select professions. The present review aimed to summarize the effects of various forms of acute exercise on creative thinking processes.
Materials and methods: An electronic search of databases such as MEDLINE through PubMed, ProQuest, and Google Scholar was performed to retrieve appropriate reference literature. The period was set from inception till November 2021 to identify relevant English language peer-reviewed articles on exercise and creativity. Eight articles were selected for review after shortlisting from the relevant literature.
Results: Studies reveal that a wide range of participants (children and adults; athletes and non-athletes) benefited from acute exercise-induced enhanced creative thinking. Majority of the studies employed objective measurements of exercise-enhanced creativity. Various forms of exercise (walking, running, jogging, cycling, swimming, etc.) enhanced the creative thinking processes.
Conclusion: Though most forms of acute exercise enhanced the creative thinking processes, exercise forms that are aerobic in nature, involving a wide range of body movements, and performed for a longer period of time, had the most beneficial effects on creativity.
Polycystic ovary syndrome (PCOS) is one of the growing disorders among women. The factors causing PCOS are majorly hormonal, and include genetic factors as well as the environmental factors. However, research is still on to understand the causes of PCOS completely. Polycystic ovary syndrome not only affects women physically but also psychologically and socially. All the symptoms are interconnected and hence affects a woman's overall health leading to a deteriorated quality of life. Treatments for PCOS often address the physical aspects of the syndrome, but not the psychological or social outcomes. A holistic outlook would perhaps work on creating an impact not only physically but also from the mind–body level. Music therapy (MT) is a treatment modality that has been found to work from all perspectives of physical, psychological, and social factors. The objective of this position paper is to understand the need and the effect of MT on women diagnosed with PCOS.
