The role of diphenhydramine HCl on tumor necrosis factor-α levels in wistar rats with traumatic brain injury: An in vivo study.

Background: Traumatic brain injury (TBI) is a major cause of death and disability worldwide that imposes a significant burden on both individuals and their families. Many of the symptoms experienced by patients with TBI are thought to be mediated by the neuroinflammatory process that occurs after the primary injury. Therefore, the present study aimed to determine the effect of diphenhydramine HCl (DPM) on serum levels of the inflammatory cytokine tumor necrosis factor-α (TNF-α) after TBI. Materials and methods: This was an experimental study with a pre- and post-test control group design. A total of 10 adult Wistar rats were divided into 2 groups, the DPM group and the placebo group. The effect of DPM on serum levels of TNF-α was evaluated at 30 min, 2 h, and 24 h after the induction of experimental TBI in the rats using Marmarou's weight-drop model. Results: TNF-α levels in the DPM group significantly decreased from 0 min to 24 h after TBI (p = 0.004). In the placebo group, TNF-α levels significantly increased from 0 min to 24 h after TBI (p < 0.001). Post hoc analysis found that TNF-α levels in the DPM group decreased significantly from 30 min to 2 h and from 2 h to 24 h after TBI (p = 0.019 and p = 0.005, respectively). Conclusion: The results of this study suggest that administration of DPM causes a reduction in serum levels of TNF-α, indicating that DPM has a significant anti-inflammatory effect in experimental rats after TBI.

Correlation between Radiological Images and Histopathological Type of Meningioma: A Cohort Study.

Background: Histologically affirmed meningiomas represent 37.6% of all essential central nervous system tumors and half of all types of critical central nervous system tumors. This study compares computed tomography (CT) scans of the head with histological findings to establish the characteristics of different types of meningiomas observed in eastern Indonesia. Methods: This prospective study evaluated 224 patients by examining the correlation between histological and CT data collected from January to December 2020 at Wahidin Sudirohusodo Hospital, Makassar, Indonesia. We assessed data including the location of pre- and post-contrast CT scans, number of tumors, margin, density, contrast enhancement, bony reaction, calcification, and perifocal edema. Patients underwent biopsies followed by an examination of the anatomical pathology tissue. Results: The female-to-male ratio of participants was 4.2 to 1, and the highest incidence was observed in participants of both genders aged 40-60 years. The most common meningioma subtype was meningothelial, while the most commonly observed locations involved the convexity and sphenoid regions. Most meningiomas had well-defined margins on CT imaging: 54.5% of patients exhibited isodense lesions on pre-contrast scans, and 64.7% exhibited high-contrast enhancement. Bone destruction developed in 4.1% of patients, while hyperostosis was observed in 17.4%, and calcification was present in 10.3% of the participants. Edema was identified in 65.2% of cases, of which moderate edema was the most common manifestation. Conclusion: Meningioma should be highly suspected in female patients aged 40-60 with isodense lesions on pre-contrast CT scans and high-contrast enhancement on post-contrast CT scans. Meningiomas were primarily classified as convexity meningiomas with well-defined margins. The presence of hyperostosis, calcification, and brain edema supported the meningioma diagnosis.

Algorithm of traumatic brain injury management at Indonesia in the COVID 19 pandemic ERA. Retrospective cohort study.

OBJECTIVES: COVID-19, a global pandemic, affects neurosurgical care in Indonesia. This study has objective to propose guideline and algorithm recommendation for the management of TBI patients during this pandemic, which can be used flexibly at neurosurgery centers, both in Indonesia and throughout the world. METHODS: We performed retrospective Cohort analysis from TBI database at tertiary public general hospitals. All neurotrauma cases from mid-February until mid-August 2020 was included in this study. The chronology of COVID-19 pandemics impact in Indonesia was defined by early period from mid-February until end of May 2020, and late period are latter. All subjects undergone the screening and perioperative measures that based on our proposes scoring system and algorithm as follows. RESULTS: There are many guidelines that explain screening methods in neurosurgery patients in general, as well as neurotrauma in particular. But here, we proposed our own scoring and screening algorithm that has been developed based on conditions in Indonesia. In total of 757 neurotrauma cases data were collected from the pandemic starts in Indonesia. DISCUSSION: Screening is a crucial initial step in this pandemic period, not only for COVID patients, but also all patients who enter the emergency room. The use of PPE is a necessity in several neurosurgery centers, especially with high COVID-19 case rates. CONCLUSION: The management of neurotrauma patients with suspected and confirmed COVID-19 requires special attention, starting from admission of the patient in ER. Rapid scoring and screening are important and the highest level of PPE is mandatory during patient care.

Progesterone Receptor Expression and Score Differences in Determining Grade and Subtype of Meningioma.

Background Meningioma is the most common brain tumor in which therapy and monitoring depend on the histopathological grade (World Health Organization [WHO] Grade). Progesterone receptor (PR) expression was reported positive in meningothelial cells and meningiomas with various degrees of positivity. We evaluated PR expression to determine its correlation with WHO Grade and each subtype of meningioma. Materials and Methods This study used 70 samples of paraffin block that were diagnosed as meningioma and classified into WHO Grade I, II, and III. The paraffin blocks were sectioned in 5 µm thickness and immunohistochemically stained with the anti-PR antibody. Results PR expression was found positive in WHO Grade I and II groups, but negative in WHO Grade III group with the score of +2 found in clear cell and atypical subtype. These results were statistically significant with p -value < 0.05. Conclusion PR can be used as an additional marker to determine WHO Grade and subtype of meningioma.

Traumatic Atlantoaxial Dislocation with Type II Odontoid Fractures: A Case Report.

BACKGROUND: Odontoid fracture frequently ensues after a cervical trauma, and most commonly at the junction between the dens and the body (type II odontoid fracture). CASE PRESENTATION: This report is focused on a 24-years-old male patient with right-sided hemiparesis, resulting from traumatic atlantoaxial dislocation with type II odontoid fracture. Cervical CT-scanning showed a spondylolisthesis of the C1-C2 complex with type II odontoid fracture, and the injury was treated using posterior reduction and internal stabilization. Therefore, hemiparesis was reduced, and during the follow-up period, our patients were disease-free. CONCLUSION: Early diagnosis and the appropriate management of atlantoaxial trauma is a possible approach towards preventing severe neurological deficits.
