Article Synopsis
  • The study focuses on the sphenoid sinus (SS), which is significant in neurosurgery due to its proximity to vital neurovascular structures.
  • It involved analyzing helical CT scans from 49 patients (21 females, 28 males) to measure the volumetric differences in the SS between genders.
  • The results showed that males had larger volumes of the SS compared to females, with a statistically significant difference in side asymmetry, suggesting that gender-related factors may influence the size of the SS during the pneumatization process.

The aim of the present study was to investigate whether the analgesic solution prepared for periarticular injection (PAI) could be utilized as a genicular nerve blockade (GNB) agent in bilateral knee arthroplasty, and to assess the pain control efficacy of this approach in comparison with PAI. This was a retrospective cohort in which patients undergoing simultaneous bilateral total knee arthroplasty (TKA) were evaluated. Thirty patients were enrolled.

Aim: To determine the relationship between the occurrence of lumbar L4-5 disc herniation (LDH) and the size of psoas muscles.

Material And Methods: The cross-sectional areas (CSAs) of the psoas muscles were measured at the L4-5 disc level on axial MRI of patients with LDH who were admitted to the hospital between 1 January 2020 and 1 June 2020. The patients were divided into three groups according to the involvement side of LDH as the patients without disc (Group I), right side disc (Group II), and left side disc (Group III).

Objective: Ponticulus posticus is an anomaly of the atlas. Odontoid fracture type 2 fracture occurs by hyperflexion, hyperextension, lateral flexion, and a combination of these movements. The presence of Ponticulus Posticus anomaly may affect the occurrence of odontoid fractures of the C2 vertebra.

Background: Different techniques are used for the remplissage procedure, including the double-pulley and mattress suture techniques. Both techniques have shown good results; however, it is unclear if one technique is superior.

Hypothesis: The remplissage procedure using the double-pulley technique with 2 anchors would have superior functional and radiological outcomes compared with the mattress suture technique with a single anchor.

In the medical literature, some case reports on the association of the COVID-19 infection and occurrence of spontaneous subarachnoid hemorrhage (SAH)have been reported Aim of the present paper is to search the causes of this association The diagnosis of COVID-19 was based on the real-time reverse-transcription polymerase chain reaction (PCR) test and computed tomography (CT) of the chest. There were four patients, whose median ages were 46,758, ranged 36-54 years). In conclusion, Spontaneous SAH can occur in the early and late course of COVID-19 infection.

Osteoid osteoma (OO) is a benign, small, and painful tumor typically seen in the subcortical shaft and metaphysis of the long bones of the lower limb. The occurrence of this type of tumor on the talar neck is rare and may cause limitation of range of motion of the ankle joint. In this article, a 17-year-old male patient had ankle pain and limitation of joint motion accompanied by synovitis.

Purpose/aim Of The Study: Detailed analysis of retinal structure such as the retinal nerve fiber layer can be performed by spectral-domain optical coherence tomography (OCT). There are no published studies concerning a relationship between retinal nerve fiber layer and human sphenoid sinus volumes. We investigated this relationship.

Objective: The autonomic nervous system dysfunctions following subarachnoid hemorrhage (SAH) are common in neurosurgical clinical practice. The aim of the study is to investigate the effect of Asian neuroscientists on the studies of autonomic nervous system dysfunction following experimental subarachnoid hemorrhage.

Methods: A systematic search was conducted using the MEDLINE and Web of Science databases for studies pertaining to SAH and autonomic nervous system dysfunction.

Background/aims: Many systems including the cardiovascular system (ischemic heart diseases, heart failure, and hypertension) may act as comorbidities that can be seen during the course of chronic obstructive pulmonary disease (COPD). Comorbidities affect the severity and prognosis of COPD negatively. Nearly 25% of patients with COPD die due to cardiovascular diseases.

Objective: The aim of the present study was to assess the efficacy and safety of tolvaptan for severe hyponatremia (SH) in hypervolemic heart failure (HF) patients within daily clinical practice.

Methods: We restrospectively reviewed our database on tolvaptan as an add-on treatment in hypervolemic patients admitted to our clinic due to deterioration of HF and having hyponatremia resistant to standard therapy. Severe hyponatremia was defined as serum sodium concentration ≤125 mEq/L.

Background: Lumbar disc herniations have been extensively studied in the literature. Asymmetric trunk muscle anatomy could affect the development of this entity which has never been quantitatively studied previously. The purpose of this manuscript was to analyze the operated sides of herniated lumbar disc.

Background: The treatment of unstable thoracolumbar fractures remains controversial. Long-segment pedicle screw constructs may be stiffer and impart greater forces on adjacent segments compared with short-segment constructs. Short-segment pedicle screw fixation alone may be associated with instrumentation failure.

Background: Contrast induced nephropathy (CIN) has been proven to be a clinical condition related to adverse cardiovascular outcomes. In recent studies, the monocyte to high density lipoprotein ratio (MHR) has been postulated as a novel parameter associated with adverse renal and cardiovascular outcomes. In this study we investigated the association of MHR with CIN in ST-segment elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (PCI).
