Radiological examination of the relationship between the pterygomaxillary junction and fracture pattern.
Le Fort 1 (LF1) osteotomies are widely used to correct midface deformities. To move the maxilla freely, the ptery-gomaxillary junction (PMJ) must be separated. When performing this osteotomy, the pterygoid plate must remain intact. The objective of this study was to evaluate relationship between the anatomical features of the PMJ and fracture patterns in LF1 osteotomy. ⋯ Anatomical variations make it difficult to separate the PMJ properly. Low thickness of PMJ increases the risk of unwanted fractures; however, according to our experience, the use of an osteotome with an incorrect angle, excessive force, and inexperienced surgeons can also cause undesirable pterygoid plate fractures.

Case ReportsDouble peptic ulcer perforation in a Covid-19 patient, extremely rare entity.
Peptic ulcer perforation is one of the leading causes of acute abdomen, presenting with acute abdominal pain and severe distress for the patient. In one-third of patients, the presentation is less dramatic, resulting in significant delays in diagnosis. Herein, we present a very rarest case operated on for diffuse purulent peritonitis with double perforation of the stomach in a COVID-19-positive patient, which had a depressing outcome.

The predictive effect of neutrophil-lymphocyte and platelet-lymphocyte ratios in the post-operative recurrence of temporomandibular joint ankylosis.
Reankylosis is a frequent pathology in patients who are operated for post-traumatic temporomandibular joint (TMJ) ankylosis. In the current practice, ankylosing spondylitis attacks are monitored with the increases in neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR). In this study, such a relation between TMJ reankylosis and increase in these ratios was evaluated. ⋯ PLR and NLR may be utilized for predicting reankylosis, respectively, in children and adults who were operated for ankylosis due to TMJ fractures.

The determination of the protective role of sildenafil administration in rats with sepsis-induced liver injury.
Sepsis is a complex syndrome which comes out after infection, characterized by activation of inflammation and infection and has a high morbidity and mortality. Sildenafil (SLD) is a selective phosphodiesterase Type 5 enzyme inhibitor and is used in the treatment of erectile dysfunction effectively all over the world. In this study, we investigated whether SLD had protective effect or not by studying the effect of SLD on reactive oxygen species and antioxidants in cecal ligation and puncture (CLP) polymicrobial sepsis model in rat liver histopathologically and biochemically. ⋯ It was shown that acute SLD administration decreased liver damage in septic rats dose-dependently in this study. In addition, it was observed that it corrected the broken oxidant-antioxidant balance. This might mediate the protective effect of SLD in liver. However, we believe that new experimental and clinical studies should be in the future to understand the protective effect of SLD in liver.

Histopathological efficacy of tacrolimus in an experimental head trauma study.
This study aimed to investigate the protective effect of tacrolimus (FK506), an immunosuppressive agent, on secondary brain damage in rats with experimental head trauma. ⋯ It was observed that the group treated with FK506 had a statistically significant increase in gliosis in the traumatic area compared to the other control groups. This shows that FK506 cannot prevent and even increase gliosis by a mechanism that has not yet been clarified. In conclusion, it is obvious that the FK506 immunosuppressive agent does not reduce post-traumatic brain injury; on the contrary, it increases gliosis.
