Objective: The effect of the frontal lobe on cognitive functions is a subject that has been studied frequently. However, cognitive impairments that can be seen in frontal lobe epilepsy are less addressed. In previous studies on decision-making disorders in patients with epilepsy, patients with temporal lobe epilepsy (TLE) were frequently studied, and it was reported that decision-making disorders could be encountered in this patient group.

We present highly efficient green, yellow, and red filters based on a metal-dielectric structure. The filters encompass only five layers of alternating zinc tin oxide and silver thin films that are grown on soda lime glass and white light-emitting diodes (LEDs) using direct current magnetron sputtering at room temperature. The designed filters provide efficient color filtering in the visible spectrum.

Article Synopsis
  • - This study aims to showcase a video training tool designed to teach complete mesocolic excision (CME) for right-sided colon cancer and to evaluate its long-term cancer outcomes after implementation.
  • - The training module includes various educational videos, starting from 3D animations to real-life surgical demonstrations, aimed at standardizing CME techniques in clinical practice.
  • - Results show that after the training was applied, there was a notable improvement in 5-year overall and disease-free survival rates for patients undergoing CME, highlighting the effectiveness of this educational approach in enhancing surgical outcomes.

Objective: The aim was to compare the effects of low tidal volume (VT) and moderate positive end-expiratory pressure (PEEP) with high VT and zero end-expiratory pressure (ZEEP) on postoperative pulmonary functions and oxygenation in patients undergoing robot-assisted laparoscopic radical prostatectomy.

Subjects And Methods: Forty-four patients were randomized into low VT-PEEP and high VT-ZEEP groups. The patients were ventilated with a VT of 6 mL/kg and 8 cm H2O PEEP in the low VT-PEEP group and a VT of 10 mL/kg and 0 cm H2O PEEP in the high VT-ZEEP group.

Recently, we showed that murine dorsal root ganglion (DRG) Car8 expression is a cis-regulated eQTL that determines analgesic responses. In this report, we show that transduction through sciatic nerve injection of DRG with human wild-type carbonic anhydrase-8 using adeno-associated virus viral particles (AAV8-V5-CA8WT) produces analgesia in naive male C57BL/6J mice and antihyperalgesia after carrageenan treatment. A peak mean increase of about 4 s in thermal hindpaw withdrawal latency equaled increases in thermal withdrawal latency produced by 10 mg/kg intraperitoneal morphine in these mice.

Background: The postdural puncture headache (PDPH) and postdural puncture backache (PDPB) are well-known complications of spinal anesthesia. There are some attempts to reduce the frequency of complication such as different design of the spinal needles.

Aims: The primary outcome of this study is to compare the incidence of PDPH between 26-gauge Atraucan and 26-gauge Quincke spinal needles in elective cesarean operations.

Carbonic anhydrase-8 (Car8 mouse gene symbol) is devoid of enzymatic activity, but instead functions as an allosteric inhibitor of inositol trisphosphate receptor-1 (ITPR1) to regulate this intracellular calcium release channel important in synaptic functions and neuronal excitability. Causative mutations in ITPR1 and carbonic anhydrase-8 in mice and humans are associated with certain subtypes of spinal cerebellar ataxia (SCA). SCA mice are genetically deficient in dorsal root ganglia (DRG) Car8 expression and display mechanical and thermal hypersensitivity and susceptibility to subacute and chronic inflammatory pain behaviors.

Background: Sevoflurane is a commonly used inhalation agent. There are two forms of sevoflurane in Turkey. The aim of this study was to evaluate the effects of original versus generic sevoflurane products on hemodynamics, time to reach 1 MAC level, inspired and expired sevoflurane levels and postoperative recovery profile.

Objective: In this study, the effect of perioperative uses of low dose ketamine on post-operative wound pain and analgesic consumption in patients undergoing elective Cesarean section was evaluated.

Methods: In randomized, double blind clinical trial, 52 women with American Society of Anesthesiologists (ASA) class I-II identification undergoing elective Cesarean section in general anesthesia were enrolled. In the ketamine group (group K), a ketamine bolus of 0.

Diaphragmatic hernia is usually congenital. However, it is rarely traumatic and can stay asymptomatic. In this report, we aimed to present the anaesthetic management of a patient with diaphragmatic hernia due to previous trauma (14 years ago), which was diagnosed incidentally during surgery for rectal cancer.

Objective: Axillary plexus block is one of the widely used technique for upper extremity surgery. In this study, we retrospectively evaluated the single injection axillary plexus block technique we used in our rutine anesthesia practice, between August 2010-March 2011.

Methods: Medical records of ASA I-III, 40 17 female and 23 male patients who underwent elective single injection axillary block performed by neurostimulation technique in elective distal part of the arm, forearm and hand surgeries were evaluated, retrospectively.

Objective: To investigate to what effect active subdiaphragmatic gas aspiration reduces pain after a laparoscopic cholecystectomy.

Materials And Methods: A total of 104 patients undergoing laparoscopic cholecystectomy were randomly placed into 2 groups. Group I included active subdiaphragmatic gas aspiration (n=52) while group II included simple evacuation (n=52) without any additional procedures.

The aging of the population is one of the most important demographic events of the 21st century. The aim of this study is to define the basic variables related with criminal behavior among the elderly for cases over 60 years. A retrospective assessment of the criminal data (255 cases) consists of the period between 2000 and 2005 of the Council of Forensic Medicine, Turkish Ministry of Justice.
