Dural ectasia and intracranial hypotension in Marfan syndrome. / Ectasia dural e hipotensión endocraneal en síndrome de Marfán.

INTRODUCTION: Marfan syndrome is an autosomal dominant, multi-systemic connective tissue di sorder of different presentations. Dural ectasia is a common, but little known complication that can be associated with intracranial hypotension syndrome (IHS). OBJECTIVE: To present a case of severe headache secondary to IHS in order to warn about this rare complication, which must be considered in children carriers of connective tissue diseases, especially Marfan syndrome. CLINICAL CASE: 13-year- old female carrier of Marfan syndrome, clinically diagnosed according to the 2010 Ghent criteria, who consulted due to a 6-months history of severe orthostatic headache. Head magnetic resonance imaging (MRI) showed multiple signs of intracranial hypotension, while whole-spine MRI showed dural ectasia that caused the thecal sac dilation and subsequent remodeling of vertebral bodies, es pecially the sacral ones. Treatment with an autologous epidural blood patch was administered with good clinical response. CONCLUSIONS: Dural ectasia, frequent in Marfan syndrome, is a predisposing cause of cerebrospinal fluid (CSF) leakage, which could cause orthostatic headache secondary to IHS.

Paraganglioma in pregnancy: interdisciplinary management during pregnancy.

Paragangliomas are tumors that originate from the extra-adrenal neural crest, the incidence of which during pregnancy is not more than two to eight cases per million people per year and are known to be highly morbid. The purpose of this report is to describe the experience and results obtained during management of a primigravida diagnosed with paraganglioma on week 21.2 and received both medical and surgical management with good maternal and perinatal outcomes. This case report evidences the importance of practicing interdisciplinary management of patients with clinical suspicion of paragangliomas or pheochromocytomas during pregnancy at high-complexity centers even in a medium-income country.

[Thyroid storm associated with multiorganic dysfunction]. / Tormenta tiroidea asociada a disfunción multiorgánica.

Thyroid storm is a rare and potentially fatal condition. Unusual presentations in patients with thyroid storm have been described but multiorganic dysfunction is uncommonly seen. We describe the case of a 36-year-old woman with unknown underlying Graves's disease who developed thyroid storm. The thyroid storm score of Burch and Wartofsky was 50/140. This was complicated by acute liver failure, acute kidney injury, lactic acidosis, heart failure, bi-cytopenia, coagulopathy and rhabdomyolysis. The severe multiorgan dysfunction was reversed by prompt institution of steroids, cyclophosphamide and plasma exchange before thyroidectomy. Main difficulty lies in recognizing its varied presentations and offering appropriate treatment when physician faces either failure or contraindications of conventional therapy.

Combined hyperglycemic crises in adult patients already exist in Latin America / Las crisis hiperglucémicas combinadas en pacientes adultos ya existen en Latinoamérica

INTRODUCTION: Diabetes mellitus is one of the most common diseases worldwide, with a high morbidity and mortality rate. Its prevalence has been increasing, as well as its acute complications, such as hyperglycemic crises. Hyperglycemic crises can present with combined features of diabetic ketoacidosis and hyperosmolar state. However, their implications are not fully understood. OBJECTIVE: To describe the characteristics, outcomes, and complications of the diabetic population with hyperglycemic crises and to value the combined state in the Latin American population. MATERIALS AND METHODS: Retrospective observational study of all hyperglycemic crises treated in the intensive care unit of the Fundación Valle del Lili between January 1, 2015, and December 31, 2020. Descriptive analysis and prevalence ratio estimation for deaths were performed using the robust Poisson regression method. RESULTS: There were 317 patients with confirmed hyperglycemic crises, 43 (13.56%) with diabetic ketoacidosis, 9 (2.83%) in hyperosmolar state, and 265 (83.59%) with combined diabetic ketoacidosis and hyperosmolar state. Infection was the most frequent triggering cause (52.52%). Fatalities due to ketoacidosis occurred in four patients (9.30%) and combined diabetic ketoacidosis/hyperosmolar state in 22 patients (8.30%); no patient had a hyperosmolar state. Mechanical ventilation was associated with death occurrence (adjusted PR = 1.15; 95 % CI 95 = 1.06 - 1.24). CONCLUSIONS: The combined state was the most prevalent presentation of the hyperglycemic crisis, with a mortality rate similar to diabetic ketoacidosis. Invasive mechanical ventilation was associated with a higher occurrence of death.

Introducción. La diabetes mellitus es una de las enfermedades más frecuentes en todo el mundo, con una tasa elevada de morbimortalidad. Su prevalencia ha ido en aumento y, también, sus complicaciones agudas, como las crisis hiperglucémicas. Las crisis hiperglucémicas pueden presentar características combinadas de cetoacidosis diabética y estado hiperosmolar. Aún no se conocen completamente sus implicaciones. Objetivo. Describir las características, los resultados y las complicaciones de la población diabética con crisis hiperglucémicas, y valorar el estado mixto en la población latinoamericana. Materiales y métodos. Se trata de un estudio observacional retrospectivo de pacientes con crisis hiperglucémicas atendidos en la unidad de cuidados intensivos de la Fundación Valle del Lili, entre el 1º de enero de 2015 y el 31 de diciembre de 2020. Se realizó un análisis descriptivo y se estimó la razón de prevalencia para muerte mediante el método de regresión de Poisson. Resultados. Se incluyeron 317 pacientes con crisis hiperglucémica confirmada, 43 (13,56 %) con cetoacidosis diabética, 9 (2,83 %) en estado hiperosmolar y 265 (83,59 %) en estado mixto. La causa desencadenante más frecuente fue la infección (52,52 %). Cuatro pacientes fallecieron por cetoacidosis (9,30 %), 22 (8,30 %), por un estado mixto; ninguno se encontraba en estado hiperosmolar. La asistencia respiratoria mecánica se asoció con la muerte (razón de prevalencia ajustada = 1,15; IC95%: 1,06-1,24). Conclusiones. El estado combinado fue la presentación más prevalente de la crisis hiperglucémica, con una tasa de mortalidad similar a la de la cetoacidosis diabética, y la asistencia respiratoria mecánica invasiva se asoció con una mayor ocurrencia de muerte.

Clinical outcomes in patients with diabetes and stress hyperglycemia that developed SARS-CoV-2 infection / Desenlaces clínicos de los pacientes con diabetes e hiperglucemia de estrés que presentaron infección por SARS-CoV-2

INTRODUCTION: Diabetes and stress hyperglycemia have been related with poorer clinical outcomes in patients infected by SARS-CoV-2 and at risk for severe disease. OBJECTIVE: To evaluate clinical outcomes in three groups of patients (with diabetes, without diabetes and with stress hyperglycemia) with SARS-CoV-2 infection. MATERIALS AND METHODS: A retrospective cohort study was conducted in Cali (Colombia). We included patients 18 years old or older with a diagnosis of SARS-CoV-2 infection, managed in the emergency room, hospitalization, or intensive care unit between March 2020 and December 2021. Immunocompromised patients and pregnant women were excluded. Patients were classified into three groups: without diabetes, with diabetes, and with stress hyperglycemia. A comparison between the groups was performed. RESULTS: A total of 945 patients were included (59.6% without diabetes, 27% with diabetes, and 13.4% with stress hyperglycemia). Fifty-five-point three percent required intensive care unit management, with a higher need in patients with stress hyperglycemia (89.8%) and diabetes (67.1%), with no difference between these groups (p = 0.249). We identified a higher probability of death in the group with stress hyperglycemia versus the one without diabetes (adjusted OR = 8.12; 95% CI: 5.12-12.88; p < 0.01). Frequency of acute respiratory distress syndrome, need for invasive mechanical ventilation, use of vasopressors and inotropes, need for de novo renal replacement therapy, and mortality was higher in patients with metabolic alterations (diabetes and stress hyperglycemia). CONCLUSIONS: Diabetes and stress hyperglycemia were associated with worse clinical outcomes and mortality in patients with COVID-19. These patients should be identified early and considered them high risk at the COVID-19 diagnosis to mitigate adverse outcomes.

Introducción. La diabetes y la hiperglucemia de estrés se han relacionado con peores desenlaces clínicos en pacientes infectados por SARS-CoV-2 y con riesgo de enfermedad grave. Objetivo. Evaluar los resultados clínicos en tres grupos de pacientes (con diabetes, sin diabetes o con hiperglucemia de estrés) con infección por SARS-CoV-2. Materiales y métodos. Se llevó a cabo un estudio retrospectivo de cohorte en Cali (Colombia). Se incluyeron pacientes de 18 años o más, con diagnóstico de infección por SARS-CoV-2 atendidos en urgencias, hospitalización o unidad de cuidados intensivos entre marzo de 2020 y diciembre de 2021. Se excluyeron los pacientes inmunocomprometidos y las mujeres embarazadas. Los pacientes fueron clasificados en tres grupos: sin diabetes, con diabetes y con hiperglucemia de estrés. Se realizó una comparación entre los grupos. Resultados. Se incluyeron 945 pacientes (59,6 % sin diabetes, 27 % con diabetes y 13,4 % con hiperglucemia de estrés). El 55,3 % requirió manejo en la unidad de cuidados intensivos, con mayor necesidad por parte de los pacientes con hiperglucemia de estrés (89,8 %) y diabetes (67,1%), sin diferencia entre estos grupos (p = 0,249). Se observó una mayor probabilidad de muerte en el grupo con hiperglucemia de estrés versus sin diabetes (OR ajustado = 8,12; IC95%: 5,12-12,88; p < 0,01). La frecuencia de síndrome de distrés respiratorio agudo, necesidad de ventilación mecánica invasiva, uso de vasopresores e inotrópicos, necesidad de terapia de reemplazo renal de novo y mortalidad fue mayor en pacientes con alteraciones metabólicas (diabetes e hiperglucemia de estrés). Conclusiones. La diabetes y la hiperglucemia de estrés se asociaron a peores resultados clínicos y mortalidad en pacientes con COVID-19. Estos pacientes deben ser identificados tempranamente y considerados de alto riesgo al momento del diagnóstico de COVID-19 para mitigar los desenlaces adversos.

Clinical Experience of Using Telemedicine for the Management of Patients Using Continuous Subcutaneous Insulin Infusion in a Highly Complex Latin American Hospital.

INTRODUCTION: Continuous subcutaneous insulin infusion (CSII) has emerged as a potential solution for diabetes management during the pandemic, as it reduces the need for in-person visits and allows for remote monitoring of patients. Telemedicine has also become increasingly important in the management of diabetes during the pandemic, as it allows healthcare providers to provide remote consultations and support. Here, we discuss the implications of this approach for diabetes management beyond the pandemic, including the potential for increased access to care and improved patient outcomes. METHODS: We performed a longitudinal observational study between 1 March 2020 and 31 December 2020 to evaluate glycemic parameters in diabetic patients with CSII in a telehealth service. Glycemic parameters were time in range (TIR), time above range, time below range, mean daily glucose, glucose management indicator (GMI), and glycemic variability control. RESULTS: A total of 36 patients were included in the study, with 29 having type 1 diabetes and 6 having type 2 diabetes. The study found that the proportion of patients achieving target glucose variability and GMI remained unchanged during follow-up. However, in patients with type 2 diabetes, the time in target range increased from 70% to 80%, and the time in hyperglycemia decreased from 2% to 0%. CONCLUSIONS: The results of this study suggest that telemedicine is a strategy for maintaining glycemic control in patients using CSII. However, the lack of access to the internet and adequate telemonitoring devices make it difficult to use on a large scale in emerging countries like ours.

Identification of 17q12 microdeletion syndrome in a Latin American patient with maturity-onset diabetes of the young subtype 5: a case report.

BACKGROUND: Maturity-onset diabetes of the young comprises a large group of autosomal inherited gene mutations. Maturity-onset diabetes of the young subtype 5 is caused by mutations in the HNF1B gene. This gene is expressed in the early phase of embryonic development in the pancreas, kidneys, liver, and genital tract; therefore, kidney or urinary tract malformations are associated with diabetes mellitus. The 17q12 deletion syndrome is a cause of maturity-onset diabetes of the young subtype 5 that should be considered. CASE PRESENTATION: We present the case of a 35-year-old Hispanic female patient with a history of bicornuate uterus and polycystic renal disease that required kidney transplant. She had insulin-dependent diabetes, with her mother, maternal grandmother, and great-grandmother showing a similar clinical manifestation. Molecular analysis showed a deletion in chromosome 17q12 involving 15 genes, including HNF1B. Therefore, a diagnosis of deletion syndrome was made. CONCLUSIONS: The 17q12 deletion syndrome represents a rare genetic syndrome that involves different genes, including HNF1B. Principally, it is characterized by the combination of genitourinary tract malformations and diabetes mellitus, similar to our patient.

Moving on trial: protocol for a pilot randomised controlled trial of models of housing and support to reduce risks of COVID-19 infection and homelessness.

BACKGROUND: It is estimated that around 160,000 households in Britain experience homelessness each year, although no definitive statistics exist. Between March and September 2020, as part of the initial 'Everyone In' government response to COVID-19 in England, 10,566 people were living in emergency accommodation and nearly 18,911 people had been moved into settled accommodation. However, some forms of temporary accommodation may not be suitable as shared facilities make it impossible for people to adhere to government guidelines to reduce the spread of COVID-19. METHODS: This is parallel group, pilot randomised controlled trial. The target is to recruit three local authorities, each of which will recruit 50 participants (thus a total of approximately 150 participants). Individuals are eligible if they are aged 18 and over, in a single-person homeless household, temporarily accommodated by the LA with recourse to public funds. Participants will be randomised to receive settled accommodation (intervention group) or temporary accommodation (control group). The intervention group includes settled housing such as Private Rented Sector (low and medium support), Social Housing (low and medium support), and Housing First (High support). The control group will maintain treatment as usual. The follow-up period will last 6 months. The primary outcome is to assess the feasibility of recruitment, retention, and acceptability of trial processes against progression criteria laid out in a traffic light system (green: all criteria are met, the trial should progress as designed in this pilot; amber: the majority of criteria are met and with adaptations to methods all criteria could be met; red: the minority of criteria are met and the pilot RCT should not proceed). Secondary outcomes include assessment of completeness of data collection at 3 and 6 months and percentage of participants consenting to data linkage, as well as a process evaluation and economic evaluation. DISCUSSION: This trial will address feasibility questions associated with progression to a fully powered effectiveness trial of models of housing to reduce risk of COVID-19 infection and homelessness. TRIAL REGISTRATION: ISRCTN69564614 . Registered on December 16, 2020.

Posterior reversible encephalopathy with late postpartum eclampsia and short-term memory loss: a case report.

BACKGROUND: Late postpartum eclampsia is more frequently recognized than past reports indicate. This report describes the association of a reversible encephalopathy in a woman with late postpartum eclampsia. CASE: A woman with lupus nephritis presented 7 days postpartum with eclampsia. Postseizure findings included dramatic short-term memory loss. Although a computed tomography scan was negative, subsequent magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) demonstrated vascular changes associated with a reversible encephalopathy. Conservative treatment with analeptic and antihypertensive therapy allowed a rapid resolution of all symptomatology. CONCLUSION: In women with eclampsia and unusual neurologic findings, an MRI/MRA may be useful even in the presence of a negative computed tomography scan.

Glycemic Control and Hypoglycemia in Patients Treated with Insulin Pump Therapy: An Observational Study.

INTRODUCTION: Diabetes mellitus (DM) is a highly prevalent disease worldwide. It has been associated with an important morbimortality due to its complications and sometimes as a result of adverse events related to treatment. Insulin pump therapy (IPT) is one of the options used to control this disease and reduces one of the most frequent complication associated with treatment: hypoglycemia, which has also a great impact on life quality and clinical status of patients. MATERIALS AND METHODS: A descriptive and retrospective study was performed including patients treated and followed by the department of endocrinology from a high-complexity university hospital in Cali, Colombia, between 2012 and 2017. Patients were on IPT and continuous glucose monitoring (CGM): MiniMed Paradigm® Veo™ Insulin Pump (Medtronic®) and MiniMed 640G Insulin Pump-Enlite™ Sensor (Medtronic®). Presentation of hypoglycemia and variables associated with its development were evaluated. RESULTS: 51 patients were included. The main indication for IPT initiation was the report of hypoglycemic episodes and inappropriate metabolic control. Initiation of IPT was related with a decrease in glycosylated hemoglobin (HbA1c) and also a decrease in severe hypoglycemic events and hospitalization due to hypoglycemia. The risk factors linked with clinically significant hypoglycemia were male gender, and standard deviation of glucose measures calculated by CGM. A diminished glomerular filtration rate (GFR) (<60 mL/min/1.73 m2) was correlated with higher risk of severe hypoglycemia. CONCLUSION: IPT with CGM is a useful strategy in the management of patients with DM; it is associated with a reduction of adverse hypoglycemic events and hospitalizations due to hypoglycemia.

Risk Factors Related to New-Onset Diabetes after Renal Transplantation in Patients of a High Complexity University Hospital in Colombia, 20 Years of Experience.

INTRODUCTION: New-onset diabetes after transplantation (NODAT) is associated with immunosuppression. Its complications can negatively influence patients' quality of life, which is why it is important to study the associated risk factors and expand the possible therapies in this particular group of patients. Materials and methods. Case-control study nested in a retrospective cohort. It included patients who received kidney transplantation at the high complexity University Hospital Fundación Valle del Lili in Cali, Colombia, between 1995 and 2014. Two controls were assigned for each case, depending on the type of donor and the date of the surgery. Information was collected from clinical records and the institutional TRENAL registry. We carried out a descriptive analysis of the selected variables and identified the risk factors with conditional logistic regression. RESULTS: 122 cases were identified to which 224 controls were assigned. The median age was 44 years (IQR: 34-55), and 54% were men. Having >50 years of age at the time of transplantation (OR: 3.18, 95% CI: 1.6-6.3, p = 0.001), body mass index >30 kg/m2 (OR: 3.6, 95% CI: 1.3-9.7, p = 0.010) and being afro-descendant (OR: 2.74, 95% CI: 1.1-6.5, p = 0.023) were identified as risk factors for the development of NODAT. Pretransplant fasting plasma glucose >100 mg/dl (OR: 2.9, 95% CI: 1.4-6.4, p = 0.005) and serum triglycerides >200 mg/dl (OR: 2.5, 95% CI: 1.4-4.4, p = 0.002) were also reported as independent risk factors. CONCLUSION: We ratify some risk factors for the development of this important disease, which include certain modifiable characteristics. Interventions aimed at changes in lifestyle could be established in a timely manner before transplant surgery.

Riedel's Thyroiditis: Report of Two Cases and Literature Review.

Riedel's thyroiditis is a rare entity consisting of a fibrotic process of the thyroid which can generate gland destruction, infiltration of cervical structures and even airway obstruction. It has been associated with systemic fibrotic disorders, autoimmune diseases, and more recently with spectrum of diseases related to excess of Immunoglobulin G type 4 (IgG4). Two cases of Riedel's thyroiditis by IgG4, confirmed by immunohistochemistry and was managed surgically with favorable results during the follow-up time, are presented. These case descriptions highlight the diagnostic challenge of this disease, describe the response with surgical management, and make a brief update on the subject.

Absceso hepático en Cali, Colombia / Liver abscess in Cali, Colombia

INTRODUCCIÓN: El absceso hepático (AH) es el tipo mas común de abscesos viscerales. Se estima que el perfil epidemiológico de esta enfermedad ha cambiado con el aumento de la resistencia de los microorganismos y el uso de nuevos medicamentos. OBJETIVO: Describir las características demográficas y clínicas de los pacientes hospitalizados con diagnóstico de AH en un hospital universitario del suroccidente colombiano. MÉTODOS: Se realizó un estudio observacional retrospectivo, en la Fundación Valle del Lili, Cali, Colombia. Se incluyeron pacientes mayores de 18 años con diagnóstico de AH hospitalizados entre 2011-2020. RESULTADOS: Se incluyeron 182 pacientes. La mediana de edad fUe 56 años (rango intercuartílico, 45-67) y 62,1% fueron hombres. El microrganismo mas común fue Klebsiella pneumoniae (17,6%). La mayoría requirió drenaje percutáneo (58,2%). El 58,8% tuvo un absceso único y 54,4% fue manejado en cuidados intensivos. El 7,1% de los pacientes falleció. Al comparar los casos que fueron manejados en cuidados intensivos vs. aquellos que no lo fueron, hubo más hepatomegalia (28,3 vs. 11,0%, p = 0,004), derrame pleural derecho (48,5 vs. 28,1%, p = 0,010), cirugía (42,4 vs. 13,4%, p < 0,001), falla terapéutica (22,2 vs. 7,3%, p = 0,007) y muerte (12,1 vs. 1,2%, p = 0,005) en los atendidos en UCI. CONCLUSIÓN: Las Enterobacterales son la principal causa de AH en nuestra población. La mortalidad ha disminuido, pero la hospitalización en cuidados intensivos sigue siendo alta.

BACKGROUND: Liver abscess (LA) is the most common type of visceral abscess. It is estimated that the epidemiological profile of this disease has changed with the increase in resistance and the use of new drugs. AIM: To describe the demographic and clinical characteristics of hospitalized patients with a diagnosis of LA in a university hospital in the southwestern region of Colombia. METHODS: A. retrospective observational study was conducted at Fundación Valle del Lili, Cali, Colombia. Patients older than 18 years with a diagnosis of LA hospitalized between 2011-2020 were included. RESULTS: A total of 182 patients were included. The median age was 56 years (interquartile range, 45-67) and 62.1% were men. The most common microorganism was Klebsiella pneumoniae (17.6%). The majority required percutaneous drainage (58.2%). A 58.8% had a single abscess and 54.4% were treated in ICU. A 7.1% of the patients died. When comparing cases treated in the ICU vs. those who did not, there was more hepatomegaly (28.3 vs. 11.0%, p = 0.004), right pleural effusion (48.5 vs. 28.1%, p = 0.010), surgery (42.4 vs. 13.4%, p < 0.001), therapeutic failure (22.2 vs. 7.3%, p = 0.007) and death (12.1 vs. 1.2%, p = 0.005) in patients treated in ICU. CONCLUSION: Enterobacterales are the main cause of LA in our population. Mortality has decreased, but intensive care hospitalization remains high.

Hypophysitis an uncommon manifestation of IgG4-related disease: Case report

IgG4-related disease is a recently described disease that can involve various organs and systems. Single organ involvement is the exception to the rule, it is generally a multi-system entity. We present a 36-year-old woman, with no previous pathological history or autoimmune disease, with headache caused by cystic macroadenoma. A transsphenoidal resection was performed and pathology documented areas of fibrosis with a predominantly plasmolymphocytic infíltrate and positive IgG4 staining in more than 20 cells per high-power field, meeting diagnostic criteria for IgG4-related sclerosing disease. Involvement of other organs was ruled out, and the patient improved clinically after management.

La enfermedad relacionada con IgG4 es una entidad recientemente descrita, capaz de involucrar diversos órganos y sistemas. El compromiso de órganos aislados es la excepción a la regla, dado que generalmente se trata de una entidad multisistémica. Se presenta el caso de una mujer de 36 años, sin antecedentes patológicos previos, en quien como causa de cefalea se documenta un macroadenoma quístico llevado a resección transesfenoidal, cuyo resultado de patología documenta zonas de fibrosis con infiltrado de predominio plasmo-linfocitario y la tinción para IgG4 positiva en más de 20 células por campo de alto poder, lo que configura criterios diagnósticos para enfermedad esclerosante relacionada con IgG4; se descartó compromiso de otros órganos y hubo mejoría clínica posterior al manejo.

Hemorrhagic Cerebrovascular Disease: An Unusual Presentation of Hyperhomocysteinemia / Accidente cerebrovascular hemorrágico: una inusual presentación de hiperhomocisteinemia / Acidente vascular cerebral hemorrágico: uma apresentação incomum da hiper-homocisteinemia

Introduction: Stroke is a major cause of morbidity and mortality worldwide, with hemorrhagic stroke being the deadliest form of acute stroke. Therefore, the cause of the event should be determined to direct the associated therapy and take preventive measures. Hyperhomocysteinemia has been described as a rare etiology of stroke. Although hyperhomocysteinemia has been associated with venous thrombotic events, altered endothelial function, and procoagulant states, its clinical role in stroke remains controversial. Case description: We present a case of a 60-year-old male patient with primary autoimmune hypothyroidism who presented with dysarthria, facial paresis, and left upper-limb monoparesis after sexual intercourse. A simple skull computed tomography scan showed hyperintensity in the right basal ganglion, indicating an acute hemorrhagic event. Etiological studies were performed, including ambulatory blood pressure monitoring, cerebral angiography, and transthoracic echocardiogram, which ruled out underlying vascular pathology. During follow-up, vitamin B12 deficiency and hyperhomocysteinemia were detected, without other blood biochemical profile alterations. Supplementation was initiated, and homocysteine levels gradually decreased, without new neurological deficits observed during follow-up. Conclusion: Quantification of homocysteine should be considered in patients with a cerebrovascular disease without apparent cause, as documenting hyperhomocysteinemia and correcting its underlying etiology are essential not only for providing appropriate management but also for preventing future events.

Introducción: el accidente cerebrovascular es una causa importante de morbilidad y mortalidad en todo el mundo, y el accidente cerebrovascular hemorrágico es la forma más mortífera de accidente cerebro- vascular agudo. La determinación de la causa del evento es esencial para dirigir la terapia asociada y poder tomar medidas preventivas. La hiperhomocisteinemia se ha descrito como una etiología poco frecuente de accidente cerebrovascular. Aunque esta se ha asociado con eventos trombóticos venosos, disfunción endotelial alterada y estados procoagulantes, sigue siendo controvertido su papel clínico en el accidente cerebrovascular. Descripción del caso: se presenta el caso de un hombre de 60 años con hipotiroidismo autoinmune primario que presentó disartria, paresia facial y monoparesia del miembro superior izquierdo después de un encuentro sexual. Una simple tomografía computarizada de cráneo mostró hipointensidad en la región del ganglio basal derecho, que indicaba un evento hemorrágico agudo. Se realizaron estudios etiológicos, incluyendo monitorización ambulatoria de la presión arterial, angiografía cerebral y ecocardiograma transtorácico, que descartaron patología vascular subyacente. Durante el seguimiento, se detectó deficiencia de vitamina B12 e hiperhomocisteinemia, sin otras alteraciones en el perfil bioquímico sanguíneo. Se inició la suplementación y los niveles de homocisteína disminuyeron gradualmente, sin observar nuevos déficits neurológicos durante el seguimiento. Conclusión: la cuantificación de homocisteína debe ser considerada en casos de enfermedad cerebrovascular sin causa aparente, dado que documentar la hiperhomocisteinemia y corregir su etiología subyacente es esencial no solo para proporcionar un manejo adecuado, sino también para prevenir eventos futuros.

Introdução: o acidente vascular cerebral (AVC) é uma das principais causas de morbidade e mortalidade em todo o mundo, sendo o AVC hemorrágico a forma mais letal de AVC agudo. A determinação da causa do evento é essencial para direcionar a terapia associada e poder tomar medidas preventivas. A hiperhomocisteinemia tem sido descrita como uma etiologia rara de acidente vascular cerebral. Embora a hiper-homocisteinemia tenha sido associada a eventos trombóticos venosos, disfunção endotelial alterada e estados pró-coagulantes, seu papel clínico no AVC permanece controverso. Descrição do caso: apresentamos o caso de um homem de 60 anos com hipotireoidismo autoimune primário que apresentou disartria, paresia facial e monoparesia do membro superior esquerdo após relação sexual. A tomografia computadorizada de crânio mostrou hipointensidade na região do gânglio da base direito, indicando evento hemorrágico agudo. Foram realizados estudos etiológicos, incluindo monitorização ambulatorial da pressão arterial, angiografia cerebral e ecocardiograma transtorácico, que descartaram patologia vascular subjacente. Durante o acompanhamento, foram detectados deficiência de vitamina B12 e hiper-homocistei- nemia, sem outras alterações no perfil bioquímico sanguíneo. A suplementação foi iniciada e os níveis de homocisteína diminuíram gradualmente, sem novos déficits neurológicos observados durante o acompanhamento. Conclusão: a quantificação da homocisteína deve ser considerada em casos de doença vascular cerebral sem causa aparente, pois documentar a hiper-homocisteinemia e corrigir sua etiologia subjacente é essencial não apenas para fornecer manejo adequado, mas também para prevenir eventos futuros.

Servicio de Anestesiología del Hospital de Urgencia Asistencia Pública: ¿Quiénes somos? / Anesthesia in Asistencia Pública Hospital. Who are we?

The Asistencia Pública was founded on August 7, 1911. It was conceived as a public hospital focused on emergency medicine. Its first location was a building acquired from the Franciscan community located at N° 85 San Francisco street, at the intersection with San Carlos street (later renamed as Alonso Ovalle). A new building was inaugurated on December 15, 1967 and its infrastructure allowed the development of various services and units that modernized, expanded and improved emergency patient care. Recently, a new facility was incorporated, called Torre Valech, inaugurated in February 2019, housing modern facilities for the emergency service, the surgical pavilions and the intensive care unit. The year 1936 marked a milestone for the Anesthesiology, due to the work of Ernesto Frías, MD, specialist trained in United States and Argentina, who organized for the first time an annual anesthesia course, working on an basis. Nevertheless, the true founder of the Anesthesiology Service and Intensive Care Unit of the José Joaquín Aguirre Hospital, was Dr. Max Arriagada Loyola. He was also a pioneer in allowing medical students to do the work of technical assistants in the specialty, during their undergraduate studies. During the eighties, the Asistencia Publica's Anesthesiology Service added new specialists who were filling the available positions both, during the daytime and on call hours. Incorporation of new technology also allowed to offer more complex and safer anesthesia procedures. Teaching has been a fundamental part of the activities of the service since its creation. First with of Dr. Arriagada's disciples, then, with the Ministerial Training Program for Anesthesiologists which in 1999 became the Postgraduate Program in Anesthesiology and Resuscitation of the Universidad de Santiago de Chile. In 2013 the program was accredited for the first time.

La Asistencia Pública fue fundada el 7 de agosto de 1911, pensada como un servicio hospitalario público centrado en los pacientes de urgencia. Su primera ubicación fue un local adquirido a la comunidad franciscana ubicada en calle San Francisco N° 85 esquina de calle San Carlos (hoy Alonso Ovalle). El nuevo edificio fue inaugurado el 15 de diciembre de 1967 y su infraestructura permitió el desarrollo de varios servicios y unidades que modernizaron, ampliaron y mejoraron la atención del paciente de urgencia. Finalmente, su última ampliación, la llamada Torre Valech, fue incorporada al edificio en febrero de 2019, albergando modernas instalaciones para la urgencia, los pabellones quirúrgicos y la Unidad de Tratamiento Intensivo. El año 1936 marcó un hito en la anestesiología de la Asistencia Pública, a partir del trabajo del doctor Ernesto Frías, especializado en Estado Unidos y Buenos Aires, quien organizó en forma un curso anual de anestesia. Pero el verdadero fundador de un servicio de anestesiología y, a su vez, de la Unidad de Tratamiento Intensivo del hospital José Joaquín Aguirre, fue el Dr. Max Arriagada Loyola, quien fue iniciador de la docencia en pregrado, para que alumnos de medicina hicieral la labor de auxiliares técnicos en la especialidad. Durante la década de los 80, el desarrollo del Servicio de Anestesiología de la Posta Central significó la suma de nuevos especialistas que fueron ocupando los cargos disponibles, tanto en horario diurno como de residencia, y la incorporación de nueva tecnología que permitió ofrecer anestesias más complejas y más seguras. La docencia ha formado parte de las actividades del servicio desde su creación: primero con los discípulos del Dr. Arriagada, luego con el Programa de Formación Ministerial de Anestesiólogos y, finalmente, se convirtió en el Programa de Postgrado en Anestesiología y Reanimación de la Universidad de Santiago de Chile a partir del año 1999, acreditándose por primera vez en el año 2013.

A review of the Munidopsidae Ortmann, 1898 (Decapoda, Galatheoidea) in Chilean waters, including new records for the Southeastern Pacific.

The information about the family Munidopsidae in Chile is scarce and sparse, making identification of new material. difficult. Due to this we lack precise information about the number and accurate distribution of Chilean species. Recent expeditions to Chile have collected specimens of this group, allowing an exhaustive review of the registers and collections in four museums in the country. A total of 93 specimens from six expeditions were analyzed, belonging to twelve species, of which five represent first records for the Chilean waters. The family in Chile is now composed by 19 bathyal and abyssal species; three belong to the genus Galacantha and 16 to Munidopsis. Only three species have distributions restricted to southeastern Pacific waters (M. cochlearis, M. follirostris and M. opalescens). Three other species are widely distributed along the eastern Pacific from Alaska or from Oregon to Chile (M. aspera, M. quadrata and M. verrucosus). No relationships were observed between the extensive geographical distribution of species and the bathymetric distribution.

Ectasia dural e hipotensión endocraneal en síndrome de Marfán / Dural ectasia and intracranial hypotension in Marfan syndrome

INTRODUCCIÓN: El síndrome de Marfán es un trastorno multisistémico del tejido conectivo de herencia autosómica dominante, de expresión variable. La ectasia dural es un compromiso frecuente, pero poco conocido, que puede asociarse a síndrome de hipotensión endocraneana (SHE). OBJETIVO: Pre sentar un caso de cefalea invalidante secundario a SHE, para advertir de esta rara complicación, que debe tenerse presente en niños portadores de conectivopatías, en especial síndrome de Marfán. CASO CLÍNICO: Adolescente femenina de 13 años, portadora de sindrome de Marfán, de diagnóstico clínico según criterios de Ghent 2010, que consultó por cefalea ortostatica invalidante de 6 meses de evolución. La Resonancia Magnetica (RM) de cerebro mostró múltiples signos de hipotensión endocraneana, mientras que la RM de columna total mostró una ectasia dural que determinó la dilatación del saco tecal y remodelación posterior de los cuerpos vertebrales, especialmente a nivel del sacro. Se realizó tratamiento con parche sanguíneo autólogo epidural con buena respuesta clínica. CONCLUSIONES: La ectasia dural, frecuente en el sindrome de Marfán, es una causa predisponente a fuga de líquido cefaloraquideo (LCR), que podría causar cefalea ortostática segundaria al SHE.

INTRODUCTION: Marfan syndrome is an autosomal dominant, multi-systemic connective tissue di sorder of different presentations. Dural ectasia is a common, but little known complication that can be associated with intracranial hypotension syndrome (IHS). OBJECTIVE: To present a case of severe headache secondary to IHS in order to warn about this rare complication, which must be considered in children carriers of connective tissue diseases, especially Marfan syndrome. CLINICAL CASE: 13-year- old female carrier of Marfan syndrome, clinically diagnosed according to the 2010 Ghent criteria, who consulted due to a 6-months history of severe orthostatic headache. Head magnetic resonance imaging (MRI) showed multiple signs of intracranial hypotension, while whole-spine MRI showed dural ectasia that caused the thecal sac dilation and subsequent remodeling of vertebral bodies, es pecially the sacral ones. Treatment with an autologous epidural blood patch was administered with good clinical response. CONCLUSIONS: Dural ectasia, frequent in Marfan syndrome, is a predisposing cause of cerebrospinal fluid (CSF) leakage, which could cause orthostatic headache secondary to IHS.

Estrogen Deficiency and the Origin of Obesity during Menopause.

Sex hormones strongly influence body fat distribution and adipocyte differentiation. Estrogens and testosterone differentially affect adipocyte physiology, but the importance of estrogens in the development of metabolic diseases during menopause is disputed. Estrogens and estrogen receptors regulate various aspects of glucose and lipid metabolism. Disturbances of this metabolic signal lead to the development of metabolic syndrome and a higher cardiovascular risk in women. The absence of estrogens is a clue factor in the onset of cardiovascular disease during the menopausal period, which is characterized by lipid profile variations and predominant abdominal fat accumulation. However, influence of the absence of these hormones and its relationship to higher obesity in women during menopause are not clear. This systematic review discusses of the role of estrogens and estrogen receptors in adipocyte differentiation, and its control by the central nervous systemn and the possible role of estrogen-like compounds and endocrine disruptors chemicals are discussed. Finally, the interaction between the decrease in estrogen secretion and the prevalence of obesity in menopausal women is examined. We will consider if the absence of estrogens have a significant effect of obesity in menopausal women.

Normoglucemiantes orales y riesgo cardiovascular / Oral glucose-lowering drugs and cardiovascular risk

Resumen Introducción: la enfermedad cardiovascular es la principal causa de muerte en el mundo, así como la primera causa de morbilidad y mortalidad en pacientes con diabetes mellitus; por tanto, es importante conocer los diferentes medicamentos que existen hoy para el manejo de la diabetes mellitus y sus efectos, tanto positivos como negativos a nivel cardiovascular. De ahí que las diferentes sociedades y asociaciones científicas del mundo hayan emitido la recomendación de que todos los medicamentos para el tratamiento de la diabetes mellitus tipo 2 deben ser evaluados y certificados como seguros a nivel cardiovascular. Metodología: se hizo una búsqueda ampliada de la literatura existente acerca de los antidiabéticos actuales y sus efectos cardiovasculares. Resultados: existen diferentes tipos de medicamentos que se han relacionado con disminución o aumento del riesgo cardiovascular. En la actualidad hay evidencia que relaciona la metformina (biguanida), la empagliflozina (inhibidor del cotransportador sodio- glucosa 2) y la liraglutide (análogo de péptido similar al glucagón) con menos muerte cardiovascular y eventos cardiovasculares en pacientes con enfermedad cardiovascular establecida. Conclusión: los pacientes con enfermedad cardiovascular conocida pueden tener un beneficio adicional seleccionando medicamentos hipoglucemiantes con un mejor perfil de seguridad cardiovascular.

Abstract Introduction: Cardiovascular disease is the main cause of death worldwide, as well as the first cause of morbidity and mortality in patients with diabetes mellitus. For these reasons it is important to know the different drugs currently available to manage diabetes mellitus and their positive and negative effects at cardiovascular level. Hence, different scientific societies and associations of the world have issued the recommendation that all drugs for the treatment of type 2 diabetes mellitus must be evaluated and certified as safe at cardiovascular level. Methodology: An extensive search was carried out on the existing literature on current antidiabetic drugs and their cardiovascular effects. Results: There are different types of drugs that are associated with a decrease or increase in cardiovascular risk. Currently, there is evidence that associated metformin (biguanide), empagliflozin (sodium-glucose cotransporter 2 inhibitor), and liraglutide (a glucagon-like peptide analogue), with less cardiovascular deaths and cardiovascular events in patients with established cardiovascular disease. Conclusion: Patients with known cardiovascular disease may have an additional benefit in selecting glucose-lowering drugs with a better cardiovascular safety profile.
