AbstractEpilepsy surgery is an important treatment modality for medically refractory focal epilepsy. The outcome of surgery usually depends on the localization accuracy of the epileptogenic zone (EZ) during pre-surgical evaluation. Good localization can be achieved with various electrophysiological and neuroimaging approaches. However, each approach has its own merits and limitations. Electroencephalography (EEG) Source Imaging (ESI) is an emerging model-based computational technique to localize cortical sources of electrical activity within the brain volume, three-dimensionally. ESI based pre-surgical evaluation gives an overall clinical yield of 73–91%, depending on choice of head model, inverse solution and EEG electrode density. It is a cost effective, non-invasive method which provides valuable additional information in presurgical evaluation due to its high localizing value specifically in MRI-negative cases, extra or basal temporal lobe epilepsy, multifocal lesions such as tuberous sclerosis or cases with multiple hypotheses. Unfortunately, less than 1% of surgical centers in developing countries use this method as a part of pre-surgical evaluation. This review promotes ESI as a useful clinical tool especially for patients with lesion-negative MRI to determine EZ cost-effectively with high accuracy under the optimized conditions.

Turbulent Airflow

Objectives: We aimed to compare tympanic membrane temperature changes and the incidence of inadvertent perioperative hypothermia (IPH) in patients undergoing laparoscopic cholecystectomy under general anesthesia in laminar airflow systems (LAS-OR) and conventional turbulent airflow systems (CAS-OR). Background: Different heating, ventilation, and air-conditioning (HVAC) systems are used in the operating room (OR), such as LAS and CAS. Laminar airflow is directed directly to the patient in LAS-OR. Does laminar airflow in ORs cause faster heat loss by convection? Methods: This is a prospective, randomized study. We divided 200 patients with simple randomization (1:1), as group LAS and group CAS, and took the patients into the LAS-OR or CAS-OR for the operation. Clinical trial number: IRCT20180324039145N3. The tympanic membrane temperatures of patients were measured (°C) before anesthesia induction ( T 0) and then every 15 min during surgery ( Tn). Changes (Δ n) between T 0 and Tn were measured. Results: In the first 30 min, there was a temperature decrease of approximately 0.8 °C (1.44 °F) in both groups. Temperature decreases at 45 min were higher in group LAS than in group CAS but not statistically significant, Δ45, respectively, 0.89 (95% confidence interval [CI] [0.77, 1.02]) versus 0.77 (95% CI [0.69, 0.84]; p = .09). IPH occurred in a total of 60.9% (112 of 184) of patients in the entire surgical evaluation period in group LAS and group CAS (58.9% vs. 62.8%, p = . 59). Conclusions: IPH is seen frequently in both HVAC systems. Clinically, the advantage of HVAC systems relative to each other has not been demonstrated during laparoscopic cholecystectomy.

IntroductionPsychiatrists play an important role as members of the bariatric surgery team. A preoperative psychiatric evaluation is considered as part of a mandatory workup before approving surgery.AimsThis evaluation focuses on the identification of any pre-existing psychiatric disorders among candidates for TOGa[1], a new experimental technique of bariatric surgery, and their correlations with post surgical weight loss.Method45 obese patients underwent a psychiatric interview and several psycho diagnostic questionnaires (SCL-90; HAM-D; HAM-A; EDI; TAS).A follow-up was set each 3 months.ResultsWe found that 34.1% of surgery candidates had a current diagnosis of depression; the majority showed anxiety symptoms. We also documented dissatisfaction about body shape, desire of slimness, fear of maturity, perfectionism, bulimia and binge eating disorder. Other frequent psychiatric symptoms were somatization, sensitivity, obsession and compulsion. After 3 months from surgery we found that the best weight loss was associated to low score in HAM-A, high score in hanger-hostility item (SCL-90) and low score in sensitiveness item (SCL-90).ConclusionThe diagnosis of a psychiatric pathology during the pre-surgical evaluation can be considered a predictive negative factor for the outcome of the surgery. The predictive positive factors are firstly the nonexistence of psychiatric symptoms, secondly the high score in sensitiveness-insight item (SCL-90) and the high score in the ability to express feelings.
