Effect of Application of Platelet-Rich Plasma on Bone Regeneration after Removal of Jaw Cysts.

Platelets are involved in regeneration at sites of bony defect, apart from their function in coagulation. An autologous preparation platelet-rich plasma gel applied to sites of bony defects after surgical treatment of jaw cyst. This case-control study was conducted in Bangabandhu Sheikh Mujib Medical University (BSMMU) in the department of Oral and Maxillofacial Surgery from September 2017 to August 2018. Total 30 patients were chosen having jaw cyst. They were divided into 2 groups; Group A and Group B, where Group A got the platelet rich plasma, after removal of the cystic lesion; and Group B got the normal usual treatment. Platelet rich plasma gel was prepared using a standardized technique and applied to the surgical site of the Group A. The differences of radiographic changes between the two groups at 6th, 12th, 18th and 24th weeks after surgery were analyzed. Study showed significant changes in early bone regeneration in group A at 12th and 18th weeks post operatively. Platelet rich plasma induces early bone regeneration and it has proven successful outcome.

Multisystem inflammatory syndrome with persistent neutropenia in neonate exposed to SARS-CoV-2 virus: A case report and review of literature.

BACKGROUND: Multisystem inflammatory syndrome in Children (MIS-C) is a postinfectious immune mediated hyperinflammatory state seen in children and adolescent below 21 year of age and develop after 4-6 weeks of severe acute respiratory syndrome coronavirus -2 (SARS-CoV-2) infection, however, it is rare in neonates. We report an extremely rare and first of its kind case of MIS-C in a neonate with persistent neutropenia. CASE DESCRIPTION: A 19-day old boy presented with complaints of fever and loose stools for 1 day and developed rash after admission. Baby was investigated for sepsis and commenced on IV antibiotics empirically. In view of persistent fever, diarrhoea, rash and absence of obvious microbial etiology of inflammation, with elevated inflammatory marker and an epidemiologic link to SARS-CoV-2 infection, the diagnosis of MIS-C-was made. Intravenous immunoglobulin (IVIg) was administered and defervescence occurred within 24 hours. He also developed neutropenia during course of illness which persisted on follow up. CONCLUSION: MIS-C in neonates is uncommon and fever with elevated inflammatory markers during COVID-19 pandemic should alert the pediatrician to the possibility of MIS-C. Neutropenia may be associated with MIS-C in neonates and warrants prolonged follow up.

Clinical outcomes of management of myofacial pain dysfunction syndrome.

The purpose of the present study was to investigate two years clinical outcome of patients having myofacial pain dysfunction syndrome (MPDS). A total of 50 patients (male: 15, Female: 35, age: raged from 20 to 65 years) were included for this study. Clinical diagnosis for the assessment of anxiety and depression of each patient was performed by Hospital anxiety and depression (HAD) scale. Patients were then received either one of the following treatments: Occlusion correction only (n=14), Muscle Relaxant + anti-depressant drug (n=26), Physiotherapy + antidepressant drug + muscle relaxant (n=6) and Appliance + muscle relaxant (n= 4). Following two years observation, it was revealed that the treatment was apparently successful in 95% case; only 5% case was not successful due to their irregular visit. It can be concluded that MPDS is not primarily related to occlusal factors and a complex psycho physiological mechanism is involved in this type of pain problems.
