TEP for incarcerated groin hernias: is it feasible for experienced surgeons?

Objective: To verify if endoscopic TEP surgery performed by an experienced surgeon is a feasible procedure to treat incarcerated groin hernia.Methods: This is a retrospective study in which we analyzed data from patients submitted to TEP endoscopic surgery for treatment of incarcerated and non-incarcerated groin hernias. The surgeries were all performed by a single surgeon. We obtained data on gender, age, ASA scores, BMI, hernia site and operating time. The two groups were descriptively analyzed and statistically compared in order to verify how similar the samples were. The operative times were also compared between the groups. The first 65 surgeries were excluded in order to evaluate the hability of an experienced surgeon.Results: 323 surgeries were performed. 32 (9.9%) were cases of incarcerated hernias. In 306 cases (96%), the surgical approach used was TEP, the other 13 cases (4%) were operated by TAPP. All incarcerated hernias were operated by the TEP method. No significant differences on gender, age, hernia site, BMI and ASA score were found between incarcerated and non-incarcerated hernia patients. The operative time was analyzed by site of hernias (left, right and bilateral) and no statistical differences were found between incarcerated and nonincarcerated hernias.Conclusions: 1) There was no significant differences on gender, age, ASA, BMI and site of hernias that could interfere in operative time in both groups. 2) The lack of significant statistical difference on operative time indicate that, for experienced surgeons, the technical difficulty is similar to operate incarcerated and non-incarcerated groin hernias by TEP.Keywords: Herniorraphy; Inguinal hernia; Endoscopy; Learning curve; Operative time

Comparing dextrose prolotherapy with other substances in knee osteoarthritis pain relief: A systematic review

The objective of this study is to compare the effectiveness of dextrose-prolotherapy with other substances for pain relief in patients with primary knee osteoarthritis. The literature screening was done in January 2021 through Medline (PubMed), EMBASE, and Database of the National Institute of Health based on the following criteria: randomized clinical trials that subjected patients with primary knee osteoarthritis who underwent treatment with dextrose-prolotherapy and other substances for pain relief. Paired reviewers independently identified 3381 articles and included 8 trials that met the eligibility criteria. According to the findings of this review, participants that underwent dextrose-prolotherapy showed improvements between baseline and posterior assessments and when compared to saline injections, but when compared to other substances, the results were not clear. Although dextrose-prolotherapy is a useful treatment method by itself, it is still not possible to clearly affirm that it is superior or inferior to its counterparts. There is an urgent need for further studies to bring more evidence to the field

MICRObiota on BILIOpancreatic malignant diseases [MICROBILIO]: A systematic review

Introduction: The increase in the incidence of pancreatic and biliary cancers has attracted the search for methods of early detection of diseases and biomarkers. The authors propose to analyze new findings on the association between microbiota and Pancreatic Ductal Adenocarcinoma (PDAC) or Cholangiocarcinoma (CCA). Methods: This systematic review was carried out according to the items of Preferred Reports for Systematic Reviews and Protocol Meta-Analysis (PRISMA-P). This study was registered by the Prospective Register of Systematic Reviews (PROSPERO), identification code CRD42020192748 before the review was carried out. Articles were selected from the PUBMED, EMBASE, and Cochrane databases. Results: Most studies (86.67%) used 16s rRNA as a sequencing method. The main comorbidities found were diabetes mellitus, systemic arterial hypertension, and dyslipidemia. Many studies were limited by the small number of participants, but the biases were mostly low. There was very little concordance about the composition of the microbiome of different sites, for both case and control groups when compared to other studies' results. Bile sample analysis was the one with a greater agreement between studies, as three out of four studies found Escherichia in cases of CCA. Conclusion: There was great disagreement in the characterization of both the microbiota of cases and control groups. Studies are still scarce, making it difficult to adequately assess the data in this regard. It was not possible to specify any marker or to associate any genus of microbiota bacteria with PDAC or CCA

Role of temporary arterial occlusion in subarachnoid hemorrhage outcomes: a prospective cohort study

ABSTRACT Purpose: Temporary arterial occlusion (TAO) is a widespread practice in the surgical treatment of intracranial aneurysms. This study aimed to investigate TAO’s role during ruptured aneurysm clipping as an independent prognostic factor on short- and long-term outcomes. Methods: This prospective cohort included 180 patients with ruptured intracranial aneurysms and an indication of microsurgical treatment. Patients who died in the first 12 hours after admission were excluded. Results: TAO was associated with intraoperative rupture (IOR) (odds ratio – OR = 10.54; 95% confidence interval – 95%CI 4.72–23.55; p < 0.001) and surgical complications (OR = 2.14; 95%CI 1.11–4.07; p = 0.01). The group with TAO and IOR had no significant difference in clinical (p = 0.06) and surgical (p = 0.94) complications compared to the group that had TAO, but no IOR. Among the 111 patients followed six months after treatment, IOR, number of occlusions, and total time of occlusion were not associated with Glasgow Outcome Scale (GOS) in the follow-up (respectively, p = 0.18, p = 0.30, and p = 0.73). Among patients who underwent TAO, IOR was also not associated with GOS in the follow-up (p = 0.29). Conclusions: TAO was associated with IOR and surgical complications, being the latter independent of IOR occurrence. In long-term analysis, neither TAO nor IOR were associated with poor clinical outcomes

Seizure control in mono- and combination therapy in a cohort of patients with Idiopathic Generalized Epilepsy

Abstract Idiopathic Generalized Epilepsy (IGE) patients may not achieve optimal seizure control with monotherapy. Our goal was to evaluate the efficacy of combination therapy in a retrospective series of IGE patients receiving different antiseizure medication (ASM) regimens. We retrospectively identified all patients with adolescence onset IGE with typical clinical and EEG features from a single epilepsy specialist clinic from 2009 to 2020. We evaluated long-term seizure control, for VPA, LEV, LTG mono and combination therapy. We studied 59 patients. VPA was more commonly used in men (84%) than in women (44%) (p  0.05). Combination therapy was superior to LEV and LTG monotherapy for complete control (p = 0.03), without differences for minor seizures and pseudoresistance outcomes (p > 0.05). Combination therapy not including VPA was also non-inferior to VPA monotherapy in all settings. Combination therapy was superior to LTG and LEV monotherapy in IGE, and may be equally effective including or not VPA. Combination therapy including LTG, LEV, and/or VPA is an effective treatment option after monotherapy failure with one of these ASM in IGE. Dual therapy with LEV–LTG should be considered in monotheraphy failure, to avoid fetal effects of in utero VPA exposure

The Relationship between Injury Characteristics and Post-Traumatic Recovery after Diffuse Axonal Injury

Background: The diagnosis and prognosis of diffuse axonal injury (DAI) remain challenging. This research aimed to analyze the impact on activities of daily living (ADL), functional outcomes, quality of life (QoL), and the association between lesion severity and DAI location identified through imaging exams. Methods: This prospective cohort study included 95 patients diagnosed with DAI. Data were collected at admission, three, six, and twelve months post-injury. The associations between variables were evaluated using a mixed-effects model. Results: Functional recovery and QoL improved between three and twelve months after DAI. An interaction was observed between independence in performing ADL and subarachnoid hemorrhage (p = 0.043) and intraventricular hemorrhage (p = 0.012). Additionally, an interaction over time was observed between the Glasgow Outcome Scale (GOS) and DAI severity (p p = 0.014), and the Disability Rating Scale (DRS) with injury in brain hemispheres (p = 0.026) and Adams classification (p = 0.013). Interaction effects over time were observed with the general health perceptions and energy/vitality domains with intraventricular hemorrhage, and the social functioning domain with the obliteration of basal cisterns and Gentry’s classification. Conclusion: The use of CT in the acute phase of DAI is important for predicting outcomes. The severity and location of DAI are associated with functional outcomes, ADL, and QoL

New perspectives on assessment and understanding of the patient with cranial bone defect: a morphometric and cerebral radiodensity assessment.

Peer reviewed: TrueBACKGROUND: Skull defects after decompressive craniectomy (DC) cause physiological changes in brain function and patients can have neurologic symptoms after the surgery. The objective of this study is to evaluate whether there are morphometric changes in the cortical surface and radiodensity of brain tissue in patients undergoing cranioplasty and whether those variables are correlated with neurological prognosis. METHODS: This is a prospective cohort with 30 patients who were submitted to cranioplasty and followed for 6 months. Patients underwent simple head CT before and after cranioplasty for morphometric and cerebral radiodensity assessment. A complete neurological exam with Mini-Mental State Examination (MMSE), modified Rankin Scale, and the Barthel Index was performed to assess neurological prognosis. RESULTS: There was an improvement in all symptoms of the syndrome of the trephined, specifically for headache (p = 0.004) and intolerance changing head position (p = 0.016). Muscle strength contralateral to bone defect side also improved (p = 0.02). Midline shift of intracranial structures decreased after surgery (p = 0.004). The Anterior Distance Difference (ADif) and Posterior Distance Difference (PDif) were used to assess morphometric changes and varied significantly after surgery. PDif was weakly correlated with MMSE (p = 0.03; r = -0.4) and Barthel index (p = 0.035; r = -0.39). The ratio between the radiodensities of gray matter and white matter (GWR) was used to assess cerebral radiodensity and was also correlated with MMSE (p = 0.041; r = -0.37). CONCLUSION: Morphological anatomy and radiodensity of the cerebral cortex can be used as a tool to assess neurological prognosis after DC

Long-Term Outcomes in Severe Traumatic Brain Injury and Associated Factors: A Prospective Cohort Study

Objective: The presence of focal lesion (FL) after a severe traumatic brain injury is an important factor in determining morbidity and mortality. Despite this relevance, few studies show the pattern of recovery of patients with severe traumatic brain injury (TBI) with FL within one year. The objective of this study was to identify the pattern of recovery, independence to perform activities of daily living (ADL), and factors associated with mortality and unfavorable outcome at six and twelve months after severe TBI with FL. Methodology: This is a prospective cohort, with data collected at admission, hospital discharge, three, six, and twelve months after TBI. RESULTS: The study included 131 adults with a mean age of 34.08 years. At twelve months, 39% of the participants died, 80% were functionally independent by the Glasgow Outcome Scale Extended, 79% by the Disability Rating Scale, 79% were independent for performing ADLs by the Katz Index, and 53.9% by the Lawton Scale. Report of alcohol intake, sedation time, length of stay in intensive care (ICU LOS), Glasgow Coma Scale, trauma severity indices, hyperglycemia, blood glucose, and infection were associated with death. At six and twelve months, tachypnea, age, ICU LOS, trauma severity indices, respiratory rate, multiple radiographic injuries, and cardiac rate were associated with dependence. Conclusions: Patients have satisfactory functional recovery up to twelve months after trauma, with an accentuated improvement in the first three months. Clinical and sociodemographic variables were associated with post-trauma outcomes. Almost all victims of severe TBI with focal lesions evolved to death or independence

External validation of the Glasgow coma scale-pupils in low- to middle-income country patients with traumatic brain injury: Could "motor score-pupil" have higher prognostic value?

BACKGROUND: The objective of this study is to validate the admission Glasgow coma scale (GCS) associated with pupil response (GCS-P) to predict traumatic brain injury (TBI) patient's outcomes in a low- to middle-income country and to compare its performance with that of a simplified model combining the better motor response of the GCS and the pupilar response (MS-P). METHODS: This is a prospective cohort of patients with TBI in a tertiary trauma reference center in Brazil. Predictive values of the GCS, GCS-P, and MS-P were evaluated and compared for 14 day and in-hospital mortality outcomes and length of hospital stay (LHS). RESULTS: The study enrolled 447 patients. MS-P demonstrated better discriminative ability than GCS to predict mortality (AUC 0.736 × 0.658; P < 0.001) and higher AUC than GCS-P (0.736 × 0.704, respectively; P = 0.073). For hospital mortality, MS-P demonstrated better discrimination than GCS (AUC, 0.750 × 0.682; P < 0.001) and higher AUC than GCS-P (0.750 × 0.714; P = 0.027). Both scores were good predictors of LHS (r2 = 0.084 [GCS-P] × 0.079 [GCS] × 0.072 [MS-P]). CONCLUSION: The predictive value of the GCS, GCS-P, and MS-P scales was demonstrated, thus contributing to its external validation in low- to middle-income country

Left‐sided epileptiform activity influences language lateralization in right mesial temporal sclerosis

Abstract Objective To investigate the association between left epileptiform activity and language laterality indices (LI) in patients with right mesial temporal sclerosis (MTS). Methods Twenty‐two patients with right MTS and 22 healthy subjects underwent fMRI scanning while performing a language task. LI was calculated in multiple regions of interest (ROI). Data on the presence of left epileptiform abnormalities were obtained during prolonged video‐EEG monitoring. Results After correction for multiple comparisons, LI was reduced in the middle temporal gyrus in the left interictal epileptiform discharges (IED+) group, compared with the left IED− group (p < 0.05). Significance Using a responsive reading naming fMRI paradigm, right MTS patients who presented left temporal interictal epileptiform abnormalities on video‐EEG showed decreased LI in the middle temporal gyrus, indicating decreased left middle temporal gyrus activation, increased right middle temporal gyrus activation or a combination of both, demonstrative of language network reorganization, specially in the MTG, in this patient population. Plain Language Summary This research studied 22 patients with right mesial temporal sclerosis (a specific type of epilepsy) comparing them to 22 healthy individuals. Participants were asked to perform a language task while undergoing a special brain imaging technique (fMRI). The findings showed that patients with epilepsy displayed a change in the area of the brain typically responsible for language processing. This suggests that their brains may have adapted due to their condition, altering the way language is processed
