The importance of timing in epilepsia partialis continua

IntroductionTiming is one of the most important modifiable prognostic factors in the management of status epilepticus. Epilepsia partialis continua (EPC) is a status epilepticus subtype of highly variable, occasionally prolonged, duration. The aim of this study was to analyse the relationship between EPC duration and outcomes. MethodsWe performed an observational prospective study of all patients with EPC admitted to our tertiary hospital between 1 September 2017 and 1 September 2018. ResultsThe sample included 10 patients, of whom 9 were women; median age was 74 years. The most frequent aetiology was cerebrovascular disease (n = 6). EPC onset occurred outside the hospital in 5 patients, with a median time to hospital admission of 4 hours. The median time to treatment onset (TT) for all patients was 12.3 hours. The median time from treatment onset to EPC control (TC) was 30 hours; TC showed a strong positive correlation with TT (Spearman’s rho = 0.88). Six patients presented hyperglycaemia at onset; this was positively correlated with TC (rho = 0.71). All 6 patients with hyperglycaemia presented a brain injury explaining the EPC episode. ConclusionsDelays were observed in different phases of EPC management, which was related to longer duration of the episode. Glycaemia was also related to episode duration, probably acting as a triggering factor rather than as the aetiology.

Voxel-based morphometry for the evaluation of patients with pharmacoresistant epilepsy with apparently normal MRI.

Magnetic resonance imaging (MRI) is essential in the diagnosis of pharmacoresistant epilepsy (PRE), because patients with lesions detected by MRI have a better prognosis after surgery. Focal cortical dysplasia (FCD) is one of the most frequent etiologies of PRE but can be difficult to identify by MRI. Voxel-based morphometric analysis programs, like the Morphometric Analysis Program (MAP), have been developed to help improve MRI detection. Our objective was to evaluate the clinical usefulness of MAP in patients with PRE and an apparently normal MRI. We studied 70 patients with focal PRE and a nonlesional MRI. The 3DT1 sequence was processed with MAP, obtaining three z-score maps. Patients were classified as MAP+ if one or more z-score maps showed a suspicious area of brightness, and MAP- if the z-score maps did not show any suspicious areas. For MAP+ cases, a second-look MRI was performed with a dedicated inspection based on the MAP findings. The MAP results were correlated with the epileptogenic zone. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated. Thirty-one percent of patients were classified as MAP+ and 69% were MAP-. Results showed a sensitivity of 0.57, specificity of 0.8, PPV of 0.91, and NPV of 0.35. In 19% of patients, an FCD was found in the second-look MRI after MAP. MAP was helpful in the detection of lesions in PRE patients with a nonlesional MRI, which could have important repercussions for the clinical management and postoperative prognosis of these patients.

Prevalencia, etiología y diagnóstico de las lesiones de plexo. Descripción de una serie hospitalaria durante una década (2008-2018)

IntroductionWe analyse the prevalence, aetiology, and diagnosis of cervical-brachial and lumbo-sacral plexopathies at our hospital over a 10-year period. Material and methodsWe conducted an observational, descriptive, retrospective analysis of adult patients diagnosed with plexopathy and attended at our centre's specialist electromyography clinic between February 2008 and December 2018, inclusive. ResultsWe included 77 patients (95.1% of the cases identified), with a mean (standard deviation) age of 55.94 (16.9) years; 49 patients (60.5%) were men. Prevalence amounted to 2.37 cases per 100 000 person-years. Cervical plexopathy was the most frequent type (84% of cases). The most frequent aetiologies were trauma (27 patients; 35%), Parsonage-Turner syndrome (17 patients; 20.9%), neoplasm (12 patients; 14.8%), and idiopathic (11 patients, 13.5%). Of the 12 patients with neoplastic aetiology, neuroimaging only confirmed tumour infiltration in 4 cases (33.3%). Of the 77 patients who underwent neuroimaging studies (CT or MRI), findings were normal in 69 (85.2%; P=.004). The hospital departments most frequently attending these patients were traumatology (36.36%), neurology (11.68%), rehabilitation (10.38%), and oncology (4%). ConclusionsThe prevalence of plexopathies in our health district amounts to 2.37 cases per 100,000 person-years. In our series, the most frequent aetiology in both sexes was trauma, which was associated with younger age (under 55 years), although aetiology was unknown in more than one-third of patients. The cervical-brachial plexus was most frequently affected, and lesions to this region are more easily located with neuroimaging studies.

Socio-demographic and clinical features of patients with dementia attended in the psychiatry department

IntroductionDementia’s prevalence increases due to population aging, it has become a major public health concern.ObjectivesTo estimate the incidence of dementia and to describe the socio-demographic and clinical profile of patients attended in the psychiatry department of Gabes (Southern of Tunisia).MethodsIt was a retrospective descriptive study including all the patients who attended for the first time in the psychiatry department of Gabes, from the 1st January, 2010 to December 31, 2018, and who were diagnosed with dementia according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Socio-demographic and clinical data were assessed. The Mini Mental State Examination (MMSE) was used as a neuropsychological examination.ResultsWe included 98 patients. The mean annual hospital incidence of dementia was 2.38%. The mean age was 76.5 ± 9.8 years. Patients were married (68%), illiterate (68%) and jobless (42.9%). A family history of dementia was noted in 39.8% of patients. The common cardiovascular comorbidity was high blood pressure (41.8%). Among our patients, 30 (30.6%) were smokers. The mean age of onset of dementia was 73 ± 11 years. The mean duration of untreated dementia was 3 years [3 months to 11 years]. First symptoms were mainly memory disorders (57.3 %) and behavioral disorders (17.3%) The mean MMSE score was 14 ± 4.8. Alzheimer’s disease was the most frequent etiology of dementia (80 cases, 82.7%).ConclusionsOur study shows a high incidence of dementia and made it possible to draw up a socio-demographic and clinical profile of dementia patients.DisclosureNo significant relationships.

Epidemiology of Childhood Uveitis in a Tertiary Care Center: A 20-Year Study.

To investigate demographics and causes of pediatric uveitis in a Swiss tertiary reference center over a 20-year period. Retrospective cohort study on patients with uveitis aged less than 16 years seen at Jules-Gonin Eye Hospital between 1 January 2000 and 31 December 2019. Out of 2846 patients with uveitis seen in the Jules-Gonin Eye Hospital Ocular Immune-Infectiology Department, 317 (11.1%) were under 16 years of age and were included in this study. Median age at onset of the uveitis was 8.9 years (range 0 - 16). Anterior uveitis was the most frequent presentation (45.1%) followed by posterior uveitis in 26.2%, intermediate uveitis in 23.3%, and panuveitis in 5.4%. The inflammation was most frequently bilateral and non-granulomatous. A systemic inflammatory disease was found in 34% of the cases and an infectious cause in 24%. The repartition of the location of the uveitis was similar to previous reports from Western countries. Uveitis in juvenile idiopathic arthritis is the most frequent etiology related to a systemic disease in children. An infectious cause was found in 24% of our patients, which is a greater proportion than in adult cohorts.

Bilateral vocal fold paralysis after COVID-19 infection. Another neuro-invasive manifestation? Case series

The agent that causes the coronavirus disease (COVID-19), associated with the severe acute respiratory syndrome (SARS-CoV-2), produces a spectrum of symptoms that mainly affect the respiratory system, the central nervous system (CNS), the regulation of hemostasis and the immune system.
 Bilateral vocal fold paralysis (BVFP) is a condition of unknown incidence among infected patients, either because it is short-lived or because of the difficulty in establishing a direct cause to the virus.
 Viral infection has been described in the literature as a cause of BVFP and there is the suspicion that a proportion of the idiopathic cases are due to undiagnosed viral infections.
 Although the neurotropic mechanisms for SARS-CoV-2 remain unclear, there is strong evidence to ensure its neuroinvasive potential.
 The most frequent etiologies of BVFP are trauma, neoplasm, and neurological, but a viral origin should not be ruled out. Causality between COVID-19 and BVFP is plausible and will require further study in the short and long term.

Retrospective clinical evaluation of patients undergoing surgery for acute epidural hematoma

We aimed to evaluate mortality-associated factors among patients with acute epidural hematoma due to head trauma. Demographic characteristics, preoperative Glasgow Coma Scale score, epidural hematoma aetiology and radiological findings, accompanying systemic trauma results, hospitalisation duration, sequelae, and mortality features of patients experiencing epidural hematoma between 2014 and 2018 were evaluated. Overall, 79 patients were examined. The most frequent epidural hematoma aetiology was traffic accidents (51.9%), with temporal region being the most common epidural hematoma location (38 [48.2%] patients). Among all, 12 (15.2%) patients died and 67 (84.8%) were discharged. Of them, 57 (85.1%) patients were discharged without and 10 (14.9%) with neurological sequelae. Age>65 years (p=0.001) and low Glasgow Coma Scale score (p<0.05) were significantly associated with higher mortality. Overall mortality rate was 91.7% (p<0.001) in patients with systemic trauma accompanying epidural hematoma, with thoracic (12%) and orthopaedic (9%) trauma being the most common. Cranial injuries included linear fracture, 78.5%; pneumocephalus, 48.1%; cerebral contusion, 44.3%; traumatic subarachnoid haemorrhage, 32.9%; acute subdural hematoma; 26.6%, and collapse fracture, 15%. All cranial injuries except linear fractures were associated with high mortality (p<0.05). Epidural hematoma is associated with high mortality. Aetiology, Glasgow Coma Scale score, cranial pathology, age, and additional trauma are the major predictive mortality-associated factors.

Abstract P87: Time of Stroke Onset in Coronavirus Disease 2019 Patients Around the Globe: A Systematic Review and Analysis

Introduction: Coronavirus disease 2019 (COVID-19) has been associated with stroke, particular characteristics of these patients are not fully understood. The adequate management of these patients depends on the comprehension of factors such as temporality, clinical presentation and etiology. We hypothesize there is a differential temporal relationship between COVID-19 severity and stroke onset. Methods: Considering PRISMA guidelines, a systematic review of the literature as of July 2020 was conducted and registered on PROSPERO. Pubmed and Scopus studies reporting patients with COVID-19 and stroke were included. Clinical, sociodemographic and laboratory characteristics of patients were extracted and analyzed. Results: Forty-seven studies and 176 patients were included, with a mean age of 63.1 years (SD= 16 n=122), most of them were males (63.2% n=171). The most frequent etiology was cryptogenic (40.9% n=66), and a mean National Institute of Health Stroke Scale of 14.4 points was found (SD= 8.6 n=73). Large vessel occlusion (LVO) was reported in 65.9% patients (n=91) and these patients were younger with greater stroke severity. D-dimer, C-reactive protein, fibrinogen, ferritin and lactate dehydrogenase were elevated in most patients with reported findings. Most patients had severe COVID-19. The mean time from onset of respiratory symptoms to stroke was 9 days (SD=9.9), a shorter time was noted in those with mild and moderate disease compared with the longest time in severe disease, this difference was statistically significant (p< 0.001). Conclusions: There is a trend between the severity of COVID-19 and time to stroke onset, in which mild disease is associated with earlier stroke than severe disease. Age and stroke severity are related to the development of LVO. Inflammation and hypercoagulability markers are elevated in this disease, we propose to consider hypercoagulability secondary to COVID-19 as an underlying cause of stroke in these patients.

Etiology of intracerebral hemorrhage in children: cohort study, systematic review, and meta-analysis.

Understanding the etiological spectrum of nontraumatic pediatric intracerebral hemorrhage (pICH) is key to the diagnostic workup and care pathway. The authors aimed to evaluate the etiological spectrum of diseases underlying pICH. Children treated at the authors' institution for a pICH were included in an inception cohort initiated in 2008 and retrospectively inclusive to 2000, which was analyzed in October 2019. They then conducted a systematic review of relevant articles in PubMed published between 1990 and 2019, identifying cohorts with pICH. Identified populations and patients from the authors' cohort were pooled in a multicategory meta-analysis. A total of 243 children with pICH were analyzed in the cohort study. The final primary diagnosis was an intracranial vascular lesion in 190 patients (78.2%), a complication of a cardiac disease in 17 (7.0%), and a coagulation disorder in 14 (5.8%). Hematological and cardiological etiologies were disproportionately more frequent in children younger than 2 years (p < 0.001). The systematic review identified 1309 children in 23 relevant records pooled in the meta-analysis. Overall, there was significant heterogeneity. The dominant etiology was vascular lesion, with an aggregate prevalence of 0.59 (95% CI 0.45-0.64; p < 0.001, Q = 302.8, I2 = 92%). In 18 studies reporting a detailed etiological spectrum, arteriovenous malformation was the dominant etiology (68.3% [95% CI 64.2%-70.9%] of all vascular causes), followed by cavernoma (15.7% [95% CI 13.0%-18.2%]). The most frequent etiology of pICH is brain arteriovenous malformation. The probability of an underlying vascular etiology increases with age, and, conversely, hematological and cardiac causes are dominant causes in children younger than 2 years.

Factors associated with resistance to benzodiazepines in status epilepticus

ObjectiveTo investigate factors related to benzodiazepine (BZD) resistance in status epilepticus (SE) with a focus on their relationship with the etiology of the episode. MethodsAll SE cases in patients aged >16 years treated with BZDs were prospectively collected in our center from February 2011 to April 2019. The registry included demographics, SE type and etiology, the timing and duration of BZD administration, and the outcome. In total, 371 episodes were analyzed. ResultsMedian age at SE onset was 61.3 years; the most frequent etiology was acute symptomatic (55.8%). SE with prominent motor symptoms occurred in 63.3%. Median time to BZD administration was 2 h. We studied the correlation between two-time variables: time from SE onset to BZD administration and time from BZD administration to resolution of SE (response); we observed that timely administration correlated with a faster response in patients with prominent motor symptoms (p = 0.017), SE due to a chronic structural cerebral lesion (p = 0.004), and patients with a history of seizures (p = 0.013). In these subgroups (prominent motor symptoms or chronic structural lesion) BZD administration within the first 4.5 h was highly associated with shorter post-BZD SE duration (p < 0.001). SignificanceThe relationship between prompt BZD administration and subsequent duration of SE was found to depend to some extent on the etiology of the episode: patients with chronic structural lesions and those with previous epilepsy responded faster to BZDs. Semiology may have also its impact, as the presence of prominent motor symptoms showed also a faster response.

Impact of Treating Asymptomatic Bacteriuria in Kidney Transplant Recipients: A Prospective Cohort Study

This study aims to define the epidemiologic, clinical, and microbiological features of asymptomatic bacteriuria (AB) and cystitis in kidney transplantation recipients (KTRs), and to determine the impact of antimicrobial therapy of AB and the risk factors of cystitis. We conducted a prospective observational study of AB and cystitis in KTRs from January to June 2017. One-hundred ninety seven KTRs were included: 175 (88.8%) with AB and 22 (11.2%) with cystitis. The most frequent etiologies were Escherichia coli, Klebsiella pneumoniae, Enterococcus faecalis, and Pseudomonas aeruginosa. No differences were observed regarding the etiologies, antimicrobial susceptibility patterns, and microbiologic outcomes in AB vs. cystitis. The treatment of AB diminished the microbiological cure and increased the rates of microbiologic relapses and reinfections; in addition, treated AB patients showed a trend of developing symptomatic urinary tract infection in the following six months. The analysis of the data identified the following independent risk factors for cystitis during the six months of follow-up: AB treatment, thymoglobulin induction, previous acute pyelonephritis, and time since transplantation < 1 year. In summary, considering the lack of clinical benefits of treating AB and its impact on cystitis development in the follow-up, we support the recommendation of not screening for or treating AB.

Mucomuscular Elastic Flap for Lower Lip Vermilion Reconstruction: Experience in a Series of Cases in Pediatric Patients.

The mucocutaneous line and the lip vermilion are important structures from an esthetic standpoint but also in relation to the functionality of the mouth. In the literature, several types of flaps have been described for reparation of labial defects in adults. In this study, the authors analyze results of surgical reconstruction of the lower lip in the pediatric population using unilateral or bilateral mucomuscular elastic flaps for labial reconstruction. A retrospective analysis of 10 patients operated between 2003 and 2018 at our institution was made. The following demographic and clinical data were collected: age, sex, diagnosis, type of flap, follow-up, results, and complications. The Strasser scale was chosen for assessment of postoperative photographic results. Average age was 8.1 years (range 3-18). The most frequent etiology was arteriovenous malformation seen in 60% of cases. All cases corresponded to a defect of the lower lip. The average percentage of lip compromised was 44% and the largest length of compromise observed was 60% of the lip. Follow-up was on average 2.4 years. Esthetic results according to the Strasser method were as follows: 1 patient presented an excellent esthetic result, 5 good, 4 regular, and 0 poor.Considering the esthetic outcomes and low incidence of complications of the mucomuscular elastic flap, it is an acceptable and recommended technique of choice for lip vermilion reconstruction.

Recent Clinical Features of Intraocular Inflammation in Hokkaido, Japan - Comparison with the Previous Decade

ABSTRACT Purpose This study aimed to investigate the clinical features of intraocular inflammation (uveitis) in Hokkaido and to assess the etiology trends in comparison with those of our previous survey. Methods We retrospectively reviewed the medical records of 1,616 new referral uveitis patients (1,020 females and 596 males) in Hokkaido University Hospital between 2004 and 2014. Results Sarcoidosis was the most frequent etiology (17.4%), followed by Vogt–Koyanagi–Harada disease (8.1%), Behçet’s disease (4.5%), and human leukocyte antigen B27 -associated uveitis (2.5%). The etiologies in 48.7% of the patients were unclassified. Compared to the previous survey between 1994 and 2003, the rate of Behçet’s disease decreased and that of sarcoidosis increased. The rates of infectious uveitis and vitreoretinal lymphoma increased. Conclusion Although the order of the top four etiologies was the same in the two surveys, the rate of sarcoidosis increased and that of Behçet’s disease decreased.

Duration of post-operative antibiotic treatment in acute complicated appendicitis: systematic review and meta-analysis.

Appendicitis is the most frequent aetiology of acute abdominal pain requiring surgical treatment, with an estimated lifetime risk between 7% and 8%. Antibiotics play a substantial role in treatment, and there is considerable debate regarding the duration of antibiotics in treating appendicitis. We searched multiple databases from inception until June 2019 for peer-reviewed studies that compared different durations of antibiotic treatment after appendicectomy for acute complicated appendicitis in adults. We dichotomized reported data into short- and extended-term antibiotic use and controlled for different definitional thresholds in the meta-analysis. We generated risk ratios using restricted maximum likelihood methods and mixed effects modelling for each outcome of interest. Four observational studies involving 847 participants were included in the meta-analysis. For the primary outcomes of intra-abdominal infection, we did not find a statistically significant difference between extended- and short-term antibiotic strategies for intra-abdominal infection (Risk ratio 0.92, 95% confidence interval (CI) 0.49-1.74). Three randomized controlled trials involving 291 participants were included in a separate meta-analysis. We found that extended antibiotic usage was not associated with a statistically significant reduced risk for intra-abdominal infection (RR 0.52, 95% CI 0.21-1.29) or surgical site skin infection (RR 1.44, 95% CI 0.43-4.81). This systematic review and meta-analysis found that extended post-operative antibiotic treatment may not be associated with a reduced risk of intra-abdominal infection; however, meta-analysis was significantly limited by heterogeneity between studies and underpowered trials. Further large randomized controlled trials are needed to confirm these findings.

Associations of Clinical Characteristics and Etiology With Death in Hospitalized Chinese Children After Spontaneous Intracerebral Hemorrhage: A Single-Center, Retrospective Cohort Study.

Objective: We retrospectively analyzed clinical characteristics, etiology, and mortality risk factors in pediatric cases of non-traumatic spontaneous intracerebral hemorrhage.Methods: This study involved children between 29 days and 18 years old with confirmed spontaneous intracerebral hemorrhage based on head CT or MRI at the Second Affiliated Hospital of Wenzhou Medical University and Yuying Children's Hospital from January 2008 to March 2020. Demographic and clinical characteristics, etiology, imaging, and treatment data were collected at baseline. Potential risk factors of in-hospital death were identified using univariate analysis and multivariate logistic regression.Result: A total of 200 children (126 males, median age 5 years) were included in the study. Clinical symptoms of spontaneous intracerebral hemorrhage were typically non-specific (79.5%). One third of patients (31.1%) had a Glasgow Coma Scale score (GCS) ≤ 8, and nearly two-thirds (60.5%) showed a combination of ventricular hemorrhage or subarachnoid hemorrhage. Supratentorial hemorrhage was more common. Cerebrovascular disease (37.0%) and hematological disease (33.5%) were the most frequent etiologies of spontaneous intracerebral hemorrhage. Most patients (74.5%) received non-surgical treatment, while 25.5% received surgical treatment. After an average of 12 days of treatment, 167 children (83.5%) survived and 33 (16.5%) died. Multivariate logistic regression showed herniation syndrome, and low GCS (≤ 8) to be associated with increased risk of mortality, while hemorrhage due to arteriovenous malformation was associated with lower risk of mortality.Conclusion: Our data suggest that cerebrovascular disease is the most common cause of spontaneous intracerebral hemorrhage among children, and that arteriovenous malformation is associated with lower risk of death in hospital. Conversely, the presence of herniation syndrome, low GCS (≤ 8) increase risk of in-hospital mortality. Our results underscore the importance of timely imaging and supplementary examinations in cases of suspected spontaneous intracerebral hemorrhage.

Applicability and prognostic value of frailty assessment tools among hospitalized patients with advanced chronic liver disease

AimTo assess and compare the feasibility and prognostic value of various frailty assessment tools among decompensated cirrhosis inpatients.MethodsOur prospective observational registry included consecutive patients admitted for cirrhosis between June 2017 and July 2018. Exclusion criteria were intensive-care unit admission, hepatocellular carcinoma outside of the Milan criteria, and other malignancies. Frailty at baseline was assessed with the Liver Frailty Index (LFI), Clinical Frailty Scale (CFS), Fried Frailty Score (FFS), and Short Physical Performance Battery test (SPPB). The follow-up lasted for at least 180 days.ResultsThe study enrolled 168 patients (35.1% women, median age 57.9 years). The most frequent primary etiology was alcohol-related liver disease (78.6%). The Median Model for End-Stage Liver Disease (MELD) was 16. The 80th percentile of frailty scores was LFI>5.4, CFS>4, FFS>3, and SPPB<5, and it identified patients with higher mortality. LFI and CFS had the highest numerical prognostic value for in-hospital, and 90- and 180-day mortality. In a bivariate analysis of the risk of death or liver transplantation, the combination of MELD and LFI had the highest concordance (0.771 ± 0.04). In a multivariate model, MELD score (HR 1.17, 95% CI 1.12-1.22), overt encephalopathy (2.39, 1.27-4.48), infection at baseline (2.32, 1.23-4.34), and numerical LFI (1.41, 1.02-1.95) were independent predictors of overall mortality.ConclusionFrailty assessment using the evaluated tools is feasible among hospitalized cirrhotic patients, identifying those with worse prognosis. CFS had the highest applicability and accuracy for the initial assessment and LFI for the initial and follow-up assessments.

Deep Surgical-Site Infection Following Thoracolumbar Instrumented Spinal Surgery: The Experience of 25 Years.

Deep surgical-site infection following thoracolumbar instrumented spinal surgery (DSITIS) is a major complication in spine surgery and its impact on long-term morbidity and mortality is yet to be determined. This article describes the characteristics and evolution of DSITIS in our center over a period of 25 years. This single-center, retrospective cohort study included patients diagnosed with DSITIS between January 1992 and December 2016 and with a minimum follow-up after infection diagnosis of 1 year. The Infectious Diseases Society of America criteria and/or Centers for Disease Control and Prevention criteria were used to define DSITIS. Patient data (epidemiological and health status), surgical data, infection characteristics and presentation, isolated microorganisms, required surgical debridements, implant removal, and major complications linked to infection were evaluated. A total of 174 patients (106 females) were included in the analysis. Mean follow-up after infection diagnosis was 40 months (56 patients with over 5 years follow-up). Adolescent idiopathic scoliosis, adult deformity, and degenerative lumbar stenosis were the most frequent etiologies for primary surgery. Presentation of infection was considered early (0-3 months since first surgery) in 59.2% of the cases, delayed (3-24 months) in 11.5%, and late (more than 24 months) in 29.3%. All patients were treated by surgical debridement. More than 1 surgical debridement was necessary in 20.7% of cases. Implants were removed in 46.6% of the patients (72.83% in the first surgical debridement). Most frequently isolated microorganisms were Staphylococcus spp, Enterobacteriaceae, and Cutibacterium acnes. Major complications appeared in 14.3% of the patients, and over 80% of them required major surgeries to resolve those complications. Late DSITIS is more frequent than previously reported. In DSITIS culprits, Staphylococcus spp, Enterobacteriaceae, and Cutibacterium acnes predominate. DSITIS produce a high rate of major complications that usually require major surgery for treatment. 3.

Subunit Principle: Key Element for Plantar Reconstruction with Free Sensate Flaps

Purpose: Plantar wounds represent a frequent practice of the plastic and reconstructive surgeon. The uniqueness and high complexity of the microarchitecture and biomechanics of the plantar region explain the complex challenge of its reconstruction. With the advances in microsurgery, including the plantar subunit principle, both applied in the restoration of plantar defects through the use of sensorineural free flaps have allowed an optimal reconstruction.Methods: A descriptive, retrospective study was carried out in a period of time established between January 2016 and January 2019, obtaining a total of 18 patients with plantar defects, reconstructed using sensory free flaps. Tissue stability, recovery of protective sensitivity, early ambulation, and correct use of footwear were evaluated.Results: The most frequent etiology was secondary to oncological resections due to melanoma (n = 12, 66.7%), followed by gunshot wounds (n = 4, 22.2%). Subunit 3 was the most frequently involved in 38.9% (n = 7). In the 88.8% of the cases, was used an anterolateral thigh flap (n = 16) and the lateral antebrachial flap in 22.2% (n = 2). The free flap survival rate was 100%. An average of seven points was obtained at 6 months based on the Semmes-Weinstein test. The mean for the return to their daily activities was 2.5 months. The patients of 94.4% (n = 17) recovered ambulation and could footwear. Conclusion: The reconstruction of plantar defects must have a systematic approached, taking the subunit principle as a central point. The treatment of plantar defects with sensorineural free flaps represent an unprecedented option for optimal reconstruction.

Bardet Biedl Syndrome: A Rare Case Report in a Tertiary Care Teaching Hospital, Dhaka, Bangladesh

Bardet Biedl Syndrome (BBS) is an infrequent ciliopathic autosomal recessive genetic disorder that produces many effects and affects various body systems. Consanguineous marriage is conventionally considered as the most frequent etiology. The primary characteristics of the disorder are gradual visual impairment caused by retinal abnormalities, excessive weight gain, learning disabilities, Postaxial Polydactyly, Hypogonadism in males, renal abnormalities (kidney malformations and/or malfunctions). It affects both males and females. There is currently no specific cure for BBS but children with BBS benefit greatly from therapies like physical, occupational, speech and vision services. We, here, have presented a young boy of 15 years with the features of Bardet Biedl Syndrome.

Left Ventricular Unloading With an IABP in Patients Undergoing Ventricular Tachycardia Ablation With ECMO Support

The authors investigated the preprocedural predictors of postprocedural intra-aortic balloon pump (IABP) need in patients undergoing transcatheter ventricular tachycardia (VT) ablation on venoarterial (VA) extracorporeal membrane oxygenation (ECMO). Observational study. Hybrid operating room and intensive care unit of a teaching hospital. Participants were 121 consecutive patients with unstable VT undergoing transcatheter ablation with VA-ECMO. In patients with postprocedural echocardiographic, radiographic, or hemodynamic signs of increased left ventricle afterload, an IABP was positioned. Patients in the IABP group were more frequently on angiotensin-converting enzyme inhibitors (58% v 37%; p = 0.03) and had lower median baseline ejection fraction (25% v 28% p = 0.05), larger end-diastolic diameter (69.7 mm ± 13.0 v 65.7 mm ± 11.3; p = 0.03), and more frequent ischemic etiology as the reason for dilated cardiomyopathy (76% v 47%; p = 0.04,) when compared with patients not requiring IABP. Postoperatively, the IABP group required longer mechanical ventilation (24 hours [20-56.5] v 23 hours [15-28]; p = 0.003), intensive care unit stay (78 hours [46-174] v 48 hours [24-72]; p < 0.001), and continuous renal replacement therapy (13.3% v 1.3%; p = 0.006). By multivariate analysis, end-diastolic diameter (odds ratio [OR]:1.08; confidence interval [CI]: 1.00-1.16; p = 0.049), ischemic dilated cardiomyopathy (OR: 8.40; CI: 2.15-32.88; p = 0.002), and more-than-moderate mitral regurgitation (OR: 4.83; CI: 1.22-19.22; p = 0.025) were independent predictors of need for IABP. The need for an IABP to unload the left ventricle can be predicted by ventricular size, medium-severe mitral valvular defect, and ischemic etiology of the dilated cardiomyopathy.
