The Challenges of Spinal Surgery Requiring Ventral Decubitus in the Critical Trauma Patient on Extracorporeal Membrane Oxygenation: A Case Report.

Extracorporeal membrane oxygenation (ECMO) provides a bypass of the lungs, ensuring blood oxygenation and carbon dioxide removal in cases of respiratory failure. The nature of the device itself creates many perioperative challenges, including fluid management and the management of anticoagulation. Surgery via the posterior approach for an unstable spinal fracture requiring the ventral decubitus position comes with its own set of difficulties, among which are the need for stability and craniocaudal alignment when rotating the patient, the risk of increased abdominal pressure, and the damage to vulnerable soft tissues like the eyes, nose, and others. The combination of these two situations creates a synergistic effect, which adds to the difficulty of the management of the situation and requires a personalized, multidisciplinary approach. We present a case of a critical trauma patient who was on venovenous ECMO as a consequence of refractory respiratory hypoxemia with an unstable mid-thoracic spinal fracture requiring surgical intervention via the posterior approach (demanding intra-operative ventral decubitus).

Anesthetic Management of the Surgical Correction of Idiopathic Scoliosis in a Teenager With Ornithine Transcarbamalyse Deficiency.

Ornithine transcarbamylase (OTC) deficiency is the most common genetic disorder of the urea cycle. These disorders are characterized by an inability to metabolize ammonia into urea, leading to hyperammonemia with variable physiological consequences and presenting important anesthetic challenges, especially the perioperative prevention of hyperammonemia and management of its consequences, should it occur. Idiopathic scoliosis (IS) is the most common spinal deformity requiring surgical treatment. This paper presents the case of a 16-year-old female with OTC deficiency who underwent spinal fusion for IS. The chosen anesthetic strategy was combined anesthesia with total intravenous general anesthesia using target-controlled infusion pumps, an erector spinae plane block (ESPB), and a multi-pronged approach to ensure metabolic control while avoiding hyperammonemia. The existing literature regarding major surgery in patients with OTC deficiency is sparse, and this paper provides one of the first case reports of a scoliosis correction surgery, as well as one of the first descriptions of prolonged propofol infusion and locoregional anesthesia with an erector spinae plane block in this context.

Microbiological profile of bloodstream infections and antimicrobial resistance patterns at a tertiary referral hospital in Amazon, Brazil.

BACKGROUND: Bloodstream infections (BSI) are a global health issue, leading to high mortality and morbidity among hospitalized patients. METHODS: A retrospective, observational and descriptive study was conducted by reviewing blood culture records collected from patients with suspected BSI, between January 2017 and December 2019. RESULTS: The most frequent antimicrobial resistant (AMR) pathogens were methicillin-resistantStaphylococcus aureus(MRSA) (40%), methicillin-resistantS. epidermidis (MRSE) (9.5%), and extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae (35.3%). CONCLUSIONS: Our findings underscore the importance of continued vigilance and advocate for the rational use of antimicrobial agents.

Serotype-associated immune response and network immunoclusters in children and adults during acute Dengue virus infection.

The present study was designed as an exploratory investigation to characterize the overall profile of chemokines, growth factors, and pro-inflammatory/regulatory cytokines during acute DENV infection according to DENV-1, DENV-2, DENV-4 serotypes and age: children: <1-10-year-old (yo); adolescents:11-20 yo; adults 21-40 yo; and older adults: 41-75 yo. The levels of soluble immunemediators were measured in serum by high-throughput microbeads array in 636 subjects including 317 DENV-infected and 319 age-matching non-infected control (NI). Overall, most soluble mediators were increased in DENV-infected patients as compared to NI group regardless of age and DENV serotype, with high magnitude order of increase for CCL2, CXCL10, IL-1ß, IFN-γ, IL1-Ra (fold change >3x), except PDGF in which no fold change was observed. Moreover, despite the age ranges, DENV-1 and DENV-4 presented increased levels of VEGF, IL-6, and TNF-α in serum but decreased levels of PDGF, while DENV-2 exhibited increased levels of CXCL8, CCL4, and IL-12. Noteworthy was that DENV-2 showed increased levels of IL-12, IL-15, IL-17, IL-4, IL-9, and IL-13, and maintained an unaltered levels of PDGF at younger ages (<1-10 yo and 11-20 yo), whereas in older ages (21-40 yo and 41-75 yo), the results showed increased levels of CCL2, IL-6, and TNF-α, but lower levels of PDGF. In general, DENV infection at younger age groups exhibited more complex network immunoclusters as compared to older age groups. Multivariate analysis revealed a clustering of DENV cases according to age for a set of soluble mediators especially in subjects infected with DENV-2 serotype. Altogether, our findings demonstrate that the profile of circulating soluble mediators differs substantially in acute DENV according to age and DENV serotypes suggesting the participation of serotype-associated immune response, which may represent a potential target for development of therapeutics and could be used to assist medical directive for precise clinical management of severe cases.

Molecular diagnosis of opportunistic infections in the central nervous system of HIV-infected adults in Manaus, Amazonas.

Background: Opportunistic infections in the central nervous system (CNS) of people with HIV/AIDS (PLWHA) remain significant contributors to morbidity and mortality, especially in resource-limited scenarios. Diagnosing these infections can be challenging, as brain imaging is non-specific and expensive. Therefore, molecular analysis of cerebrospinal fluid (CSF) may offer a more accurate and affordable method for diagnosing pathogens. Methods: We conducted extensive real-time PCR testing (qPCR) on CSF to evaluate etiological agents in PLWHA with neurological manifestations. Primers targeting DNA from specific pathogens, including cytomegalovirus (CMV), herpes simplex virus (HSV), varicella-zoster virus (VZV), Epstein-Barr virus (EBV), John Cunningham virus (JCV), Toxoplasma gondii, and human T-lymphotropic virus types 1 and 2 (HTLV-1 and HTLV-2), were used. Results: Cerebrospinal fluid samples revealed 90 pathogens (36.7%). Toxoplasma gondii was the most frequently detected pathogen, found in 22 samples (30.5%). Other pathogens included Cryptococcus sp. (7.7%), EBV (5.3%), CMV, VZV, and JCV (4.0% each). Conclusion: Despite antiretroviral therapy and medical follow-up, opportunistic central nervous system infections remain frequent in PLWHA. Herpesviruses are commonly detected, but T. gondii is the most prevalent opportunistic pathogen in our study population. Therefore, molecular diagnosis is a crucial tool for identifying opportunistic infections, even in patients undergoing treatment.

Pediatric central nervous system infections in the Amazon: clinical and laboratory profiles.

Background: Central nervous system (CNS) infections are important causes of mortality and morbidity in children, and they are related to severe problems such as hearing loss, neurological sequelae, and death. The objective was to describe clinical and laboratory exam profiles of children who were diagnosed with CNS infections. Methods: We conducted a cross-sectional study based on medical records, which included pediatric patients aged from 3 months to 15 years, with a clinical suspicion of CNS infection between January 2014 to December 2019. The pathogens were confirmed in cerebrospinal fluid (CSF) samples using Gram staining, cell culture, molecular diagnostics (PCR and qPCR), and serology. Results: Out of the 689 enrolled patients, 108 (15.6%) had laboratory-confirmed infections in CSF. The most common bacterial pathogens isolated from the culture were Neisseria meningitidis serogroup C in 19, Streptococcus pneumoniae in 11, and Haemophilus influenzae in seven samples. The viruses identified were Enterovirus, Cytomegalovirus, Varicella-zoster virus, Epstein-Barr virus, and arbovirus. No patient was found to be positive for Herpes simplex virus 1 and 2. Patients with viral infections showed altered levels of consciousness (p = 0.001) when compared to bacterial infections. Conclusion: This study shows the presence of important vaccine-preventable pathogens, and different families of viruses causing CNS infections in the pediatric patients of Manaus.

Synergic Difficulties in an Anticipated Physiologically and Anatomically Difficult Airway in a Trauma Patient: A Case Report.

The American Society of Anesthesiologists (ASA) defines a difficult airway as a clinical situation in which a physician who is trained in anesthesiology experiences difficulty or fails in either face mask ventilation, laryngoscopy, using a supraglottic airway, tracheal intubation, extubation, or front-of-neck airway. Classically, this has been defined in relation to anatomic factors, but the concept of a physiologically difficult airway has been growing in relevance, in which physiologic factors, such as hypoxemia and hypercapnia, act to reduce safe apnea times. The case reports on a trauma patient with an unstable thoracic vertebral fracture requiring correction via the posterior approach. Our patient had multiple anatomical difficult airway predictors, namely, a short neck, greatly limited neck mobility, and a Mallampati class IV airway, among others, and multiple physiological difficult airway predictors, such as a baseline hypoxemic respiratory failure and severe sleep apnea, in addition to the restrictions on mobility imposed by the fracture itself. We describe a successful perioxygenation strategy, using high-flow nasal oxygen (HFNO) during the preoxygenation, intubation, extubation, and post-anesthesia care phases, and with an awake fiberoptic intubation technique for securing the airway.

Prevalence of arboviruses and other infectious causes of skin rash in patients treated at a tertiary health unit in the Brazilian Amazon.

BACKGROUND: In the clinical course of diseases such as arboviruses, skin rashes may appear, as is often seen in other infectious diseases. The aim of this study was to estimate the prevalence of arboviruses and other infectious causes of skin rash in a tertiary health unit in Manaus, Amazonas state, Western Brazilian Amazon. METHODOLOGY/PRINCIPAL FINDINGS: This was a cross-sectional study of patients presenting with rash who sought care at Fundação de Medicina Tropical Dr. Heitor Vieira Dourado (FMT-HVD) from February 2018 to May 2019. Individuals of either gender, aged over 18 years, were invited to participate voluntarily. Infection by Zika virus (ZIKV), dengue virus (DENV), chikungunya virus (CHIKV), Mayaro virus (MAYV), Oropouche virus (OROV) and measles was evaluated using RT-qPCR (real-time polymerase chain reaction). Immunodiagnostic tests for EBV, CMV, HIV, syphilis, rubella and measles were also performed. A total of 340 participants were included, most were female (228, 67.1%) with an average age of 36.5 years (SD ± 12.2 years). The highest prevalence was of ZIKV monoinfections (65.3%, 222/340), followed by DENV (0.9%, 3/340) and CHIKV infection (0.3%, 1/340). No cases of MAYV, OROV or rubella were found. Other causes of skin rash were detected: measles (2.9%, 10/340), parvovirus B19 (0.9% 3/340), HIV (0.3%, 1/340) and syphilis 0.6% (2/340). The co-infections identified were ZIKV+HIV (0.3%, 1/340), ZIKV+measles (0.3%, 1/340), ZIKV+parvovirus B19 (0.3%, 1/340), ZIKV+EBV (0.3%, 1/340), EBV+parvovirus B19 (0.3%, 1/340), CMV+parvovirus B19 (0.6%, 2/340), CMV+syphilis (0.3%, 1/340), ZIKV+EBV+parvovirus B19 (0.3%, 1/340) and CMV+EBV+parvovirus B19 (0.9%, 3/340). Approximately one quarter of patients had no defined cause for their skin rash (25.3%, 86/340). CONCLUSIONS: Despite the benign clinical evolution of most of the diseases diagnosed in this series of cases, syndromic surveillance of diseases such as syphilis and HIV are of utmost importance. Periodic serosurveillance might also aid in evaluating the trends of endemic diseases and eventual outbreaks.

Twenty-year Follow-up of Patients With Epidemic Glomerulonephritis due to Streptococcus zooepidemicus in Brazil.

Introduction: Post-streptococcal glomerulonephritis (PSGN) has a good prognosis in children, but few studies have evaluated the long-term renal outcomes in adults with PSGN. Methods: In a follow-up study, 47 predominantly adult patients with PSGN due to group C Streptococcus zooepidemicus were reassessed 20 years after an outbreak in Nova Serrana, Brazil. We evaluated clinical characteristics, renal outcomes, and the trajectory of the estimated glomerular filtration rate (eGFR) by the creatinine-based chronic kidney disease-epidemiology collaboration equation from 5 follow-up assessments. Logistic regression and mixed-effects regression were used in the analysis. Results: After 20 years, the participants' mean age was 56.6±15.1 years. Thirty-four (72%) patients had hypertension, 21 (44.7%) had eGFR <60 ml/min per 1.73 m2, 8 of 43 (18.6%) had urine protein-to-creatinine ratio >150 mg/g, and 25 (53%) had CKD (low eGFR and/or increased proteinuria). Increasing age was associated with CKD (odds ratio: 1.07; 95% confidence interval [CI]: 1.02-1.13; P = 0.011) in multivariate analysis. The mean eGFR decline in the last 11 years of follow-up was -3.2 ml/min per 1.73 m2 per year (95% CI: -3.7 to -2.7). Older age at baseline (coefficient -1.05 ml/min per 1.73 m2 per year; 95% CI -1.28 to -0.81; P < 0.001), and hypertension 5 years after the outbreak (coefficient -7.78 ml/min/1.73 m2; 95% CI -14.67 to -0.78; P = 0.027) were associated with lower eGFR during the whole study period. Conclusion: There was a marked worsening of renal function and a high prevalence of CKD and hypertension after 20 years of PSGN outbreak. Long-term follow-up is warranted after PSGN, especially among older patients.

Implementation of a lung cancer screening initiative in HIV-infected subjects.

In this pilot program of low-dose computed tomography (LDCT) for the screening of lung cancer (LC) in a targeted population of people with HIV (PWH), its prevalence was 3.6%; the number needed to screen in order to detect one case of lung cancer was 28, clearly outweighing the risks associated with lung cancer screening. While data from additional cohorts with longitudinal measurements are needed, PWH are a target population for lung cancer screening with LDCT.

Direct Endoscopic Necrosectomy: Timing and Technique.

Walled-off pancreatic necrosis (WOPN) is one of the local complications of acute pancreatitis (AP). Several interventional techniques have been developed over the last few years. The purpose of this narrative review is to explore such methodologies, with specific focus on endoscopic drainage and direct endoscopic necrosectomy (DEN), through evaluation of their indications and timing for intervention. Findings indicated how, after the introduction of lumen-apposing metal stents (LAMS), DEN is becoming the favorite technique to treat WOPN, especially when large solid debris or infection are present. Additionally, DEN is associated with a lower adverse events rate and hospital stay, and with improved clinical outcome.

CA-125 and CCL2 may indicate inflammation in peritoneal dialysis patients / CA-125 e CCL2 podem indicar inflamação em pacientes em diálise peritoneal

Abstract Introduction: Progressive structural changes in the peritoneal membrane occur over the course of treatment in peritoneal dialysis (PD), resulting in an increase in cytokines such as CCL2 and structural changes in peritoneal membrane triggering an increase in CA-125 in dialysate, which reflects a probable local inflammatory process, with possible loss of mesothelial cells. Thus, the current study aimed to evaluate the association between plasma and CCL2 and CA-125 dialysate levels in patients undergoing PD. Methods: Cross-sectional study was conducted with 41 patients undergoing PD. The assessments of CA-125 and CCL2 levels were performed using a capture ELISA. Correlations were estimated using Spearman's correlation and the investigation of the association between the explanatory variables (CCL2) and response variable (CA-125) was done for crude ratio of arithmetic means and adjusted utilizing generalized linear models. Results: A moderate positive correlation was observed between the levels of CA-125 and CCL2 in the dialysate (rho = 0.696). A statistically significant association was found between the levels in the CCL2 and CA-125 dialysate (RoM=1.31; CI = 1.20-1.43), which remained after adjustment for age (RoM = 1.31; CI=1.19-1.44) and for time in months of PD (RoM=1.34, CI=1.22-1.48). Conclusion: The association of CA-125 levels with CCL2 in the dialysate may indicate that the local inflammatory process leads to temporary or definitive changes in peritoneal membrane. A better understanding of this pathogenesis could contribute to the discovery of new inflammatory biomarkers.

Resumo Introdução: Alterações estruturais progressivas na membrana peritoneal ocorrem no decorrer do tratamento em diálise peritoneal (DP), resultando em um aumento de citocinas como CCL2 e alterações estruturais na membrana peritoneal desencadeando um aumento de CA-125 no dialisato, o que reflete um provável processo inflamatório local, com possível perda de células mesoteliais. Assim, o presente estudo teve como objetivo avaliar a associação entre CCL2 e CA-125 no plasma e no dialisato de pacientes submetidos à DP. Métodos: Foi realizado um estudo transversal com 41 pacientes submetidos à DP. As avaliações dos níveis de CA-125 e CCL2 foram realizadas utilizando ELISA de captura. As correlações foram estimadas usando a correlação de Spearman, e a investigação da associação entre as variáveis explicativas (CCL2) e a variável resposta (CA-125) foi feita pela razão bruta das médias aritméticas e ajustada utilizando modelos lineares generalizados. Resultados: Foi observada uma correlação positiva moderada entre os níveis de CA-125 e CCL2 no dialisato (rho = 0,696). Foi encontrada uma associação estatisticamente significativa entre os níveis no dialisato de CCL2 e CA-125 (RoM=1,31; IC = 1,20-1,43), que permaneceu após ajuste por idade (RoM = 1,31; IC=1,19-1,44) e pelo tempo de DP em meses (RoM=1,34, IC=1,22-1,48). Conclusão: A associação dos níveis de CA-125 com CCL2 no dialisato pode indicar que o processo inflamatório local leva a alterações temporárias ou definitivas na membrana peritoneal. Uma melhor compreensão desta patogênese pode contribuir para a descoberta de novos biomarcadores inflamatórios.

Crohn's disease and ulcerative colitis patient-reported outcomes signs and symptoms for the remote management of inflammatory bowel disease during the COVID-19 pandemic.

BACKGROUND AND AIMS: The COVID-19 pandemic has led to a deep reorganization of hospital services including inflammatory bowel disease (IBD) units. In this situation, conversion of in-person routine follow-up visits into phone consultations might be necessary. Here we explored the feasibility of using the validated Crohn's Disease (CD) or Ulcerative Colitis (UC) Patient-Reported Outcomes Signs and Symptoms (CD- and UC-PRO/SS) to collect data about abdominal symptoms (abdominal/S) and bowel signs and symptoms (bowel/SS) remotely. METHODS: CD- and UC-PRO/SS were collected during phone consultations and compared among patients with active and inactive disease. The effectiveness of therapeutic intervention in patients with active disease was assessed by PRO/SS variation. RESULTS: Twenty-one CD and 56 UC patients were evaluated by phone. Six (28.6%) CD and 15 (26.8%) UC patients were considered to have active disease. In CD the bowel/SS but not the abdominal/S module was significantly higher in active patients (mean bowel/SS 2.50 [SE ± 0.44] active vs 0.76 [SE ± 0.18] remission, p = 0.008, AUC 0.87; mean abdominal/S 1.11 [SE ± 0.38] active vs 0.24 [SE ± 0.13] remission, p = 0.066). UC-PRO/SS measures were significantly higher in active patients as compared to patients in remission (median bowel/SS 1.63 [SE ± 0.24] active vs 0.33 [SE ± 0.04] remission; p < 0.0001, AUC 0.91; mean abdominal/S 1.03 [SE ± 0.24] vs 0.37 [SE ± 0.12]; p = 0.009, AUC 0.71). Therapy was escalated in 12 patients (3 CD and 9 UC) due to disease relapse. Therapy escalation resulted in the reduction of PRO/SS as evaluated at the subsequent phone consultation. CONCLUSIONS: PRO/SS might represent a feasible tool to evaluate disease activity and therapy outcome in IBD patients during periods of limited access to outpatient clinics.

Análise cinemática da marcha com medidas normalizadas e não-normalizadas em indivíduos hígidos: um estudo experimental / Kinematic gait analysis with normalized and non-normalized measurements in healthy individuals: an experimental study

O objetivo deste estudo foi analisar as possíveis relações entre a variável antropométrica comprimento dos membros inferiores e de passada na marcha, com valores naturais e normalizados, em velocidade auto-selecionada e acrescida de 50%, em indivíduos adultos jovens. Foram avaliados 32 sujeitos hígidos adultos entre 18-25 anos. Os deslocamentos corporais nas duas velocidades foram registrados através da técnica de cineantropometria, utilizando o software Skillspector® para quantificar o comprimento da passada entre as médias dos dados normalizadas e não-normalizadas, do segmento direito e do segmento esquerdo. A comparação entre os valores médios das passadas normalizadas e não-normalizadas, nas diferentes velocidades, foi realizada por meio do teste t student (p < 0,05), assim como o grau de associação entre o comprimento da passada e o comprimento do membro inferior, realizada pelo teste de correlação de Pearson (p < 0,05). Sendo assim, nosso estudo constatou uma correlação positiva entre as variáveis estudadas, nas duas velocidades e, uma diferença entre a passada com dados normalizados e não normalizados, em ambas as velocidades. (AU)

The aim of this study was to analyze the possible relationships between the anthropometric variable length of the lower limbs and gait stride, with natural and normalized values, at self-selected speed and increased by 50%, in young adult individuals. 32 healthy adult subjects aged 18-25 years were evaluated. Body movements at both speeds were recorded using the kinanthropometry technique, using the Skillspector® software to quantify the stride length between the normalized and nonnormalized data averages for the right and left segments. The comparison between the mean values of normalized and non-normalized strides, at different speeds, was performed using the Student t test (p < 0.05), as well as the degree of association between stride length and lower limb length, performed by the Pearson correlation test (p < 0.05). Thus, our study found a positive correlation between the variables studied, at both speeds, and a difference between the stride with normalized and non-normalized data, at both speeds. (AU)

The geography of desperation in America: Labor force participation, mobility, place, and well-being.

There are deep divisions between Americans with opportunities and hope for the future and those left behind. We explored this earlier using metrics of reported well-being and found deep desperation - and an association with premature death - among less than college educated whites. This contrasts with more hope for the future among Black and Hispanics, despite worse objective conditions. Here we extend these findings and focus on workers out of the labor force (OLF), their low well-being, and their lack of geographic mobility. The well-being of this group varies substantially across age, gender, and race. We find that those in prime age fare worse than other age groups; within prime age respondents, women report higher well-being than men, and among prime age males, whites report significantly lower well-being, worse health, and higher pain than minorities. Prime age OLF respondents - especially white males - report worse health than those in other labor market categories, suggesting that their dropout is partly due to bad health. Individuals in counties with a higher percentage of respondents still in their childhood census tracts have poorer health and little hope. Those in counties with higher percentages of adults in their parents' homes have even worse well-being and health. The state of these cohorts - and their tendency to stay in the places they grew up rather than move - is one potential explanation for the declining levels of geographic mobility in the U.S.

Seroprevalence of SARS-CoV2 in IBD Patients Treated with Biologic Therapy.

BACKGROUND AND AIMS: A similar course of COVID-19 in patients with inflammatory bowel diseases [IBD] and in the general population has been reported. However, disease prevalence in IBD patients is presently unknown. In this prospective observational study, we aimed at determining SARS-CoV2 infection prevalence in IBD patients treated with biologic therapy. METHODS: From IBD patients under biologic therapy and recruited from three different locations in Italy and Germany, 354 sera were evaluated for antibody presence by RBD ELISA. Control groups were: i] age-matched healthy subjects tested in the same time period in Milan, Italy; ii] healthy subjects collected in the pre-COVID era; iii] IBD patients under biologic therapy collected in the pre-COVID era. RESULTS: Eight out of 354 patients tested positive for the anti-RBD-SARS-CoV2 IgG antibody [prevalence 2.3%]. The percentage of IgG-positive patients among those recruited from Milan was significantly higher than among those recruited from other locations [prevalence 5.4% vs 0.4%, p <0.005]. IgG-positive patients reported a significantly higher incidence of fever, anosmia, and ageusia, and were more likely to have entered into close contact with COVID-19-positive subjects before the study enrolment. CONCLUSIONS: Seroprevalence of SARS-CoV2 in IBD patients treated with biologic therapy reflects values measured in the local general population. Specific symptoms and contact history with SARS-CoV2-infected individuals strongly increase the likelihood of SARS-CoV2 seropositivity.

Vasoespasmo cerebral relacionado a hiperglicemia en paciente con hemorragia subaracnoidea aneurismatica: caso clínico y revisión de la literatura / Cerebral vasospasm related to hyperglycemia in patient with subaracoid aneurysmatic haemorrhage: clinical case and review of literature

La hemorragia subaracnoidea aneurismática es un fenómeno muy grave asociado a altas tasas de morbimortalidad, esta depende de la severidad inicial. El control de la glucosa es uno de los cuidados que se debe tener en cuenta ya que está estrechamente relacionada con el desarrollo de las complicaciones secundarias. Se presenta el caso clínico de un paciente con antecedente de diabetes tipo 2 tratada irregularmente, que presentó una hemorragía subaracnoidea aneurismática, complicada con vasoespasmo cerebral, infarto, hidrocefalia secundaria e infecciones pulmonares en relación a hiperglicemia durante el post operatorio de difícil y refractario tratamiento. Exponemos los mecanismos fisiopatológicos que ocasionan alteraciones de los fenómenos de autorregulación vascular cerebral y en consecuencia trastornos de la perfusión cerebral que decaen sobre el estado neurológico del paciente, sobresaltando que el control de la glucemia en el transcurso de una hemorragia subaracnoidea puede ayudar a un mejor desenlace de los pacientes.

Aneurysmal subarachnoid hemorrhage is a very serious phenomenon associated with high rates of morbidity and mortality, this depends on the initial severity. The control of glucose is one of the care that must be taken into account since it is closely related to the development of secondary complications. We present the clinical case of a patient with a history of type 2 diabetes treated irregularly, who presented an aneurysmal subarachnoid hemorrhage, complicated by cerebral vasospasm, infarction, secondary hydrocephalus and pulmonary infections in relation to hyperglycemia during the post-operative period of difficult and refractory treatment. We expose the pathophysiological mechanisms that cause alterations in the cerebral vascular self-regulation phenomena and consequently cerebral perfusion disorders that decrease the neurological state of the patient, highlighting that the control of glycemia in the course of a subarachnoid hemorrhage can help a better outcome of the patients.
