Critical digital ischemia and biliary cholangitis related to graft versus host disease: A case report and systematic literature review.

RATIONALE: Chronic graft versus host disease (cGVHD) is a systemic immune-mediated complication that occurs in approximately half of patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HCT), and remains the leading cause of late morbidity and mortality. cGVHD involves a heterogeneous group of organic manifestations, many of which mimic autoimmune diseases such as scleroderma, primary biliary cholangitis, Sjögren syndrome and polymyositis. PATIENT CONCERNS: A 60-years-old female with a history of allo-HCT developed de novo cGVHD 11 months after allo-HCT with isolated liver involvement. The patient presented with jaundice, cytolysis, cholestasis and concomitant acute digital ischemia. Liver biopsy and autoimmunity tests were performed and were found to be compatible with immune-mediated liver damage. Nailfold capillaroscopy revealed microangiopathy, characterized by avascular areas and some enlarged capillaries resembled an early systemic sclerosis pattern. DIAGNOSIS: Biliary cholangitis-like and digital ischemia related to cGVHD. INTERVENTIONS: The patient was treated with high-dose prednisone and ursodeoxycholic acid, and extracorporeal photopheresis. The patient required hospital admission for administration of intravenous prostacyclin due to refractory Raynaud syndrome. OUTCOMES: After 6 to 8 weeks, the patient achieved a good response, with evident clinical improvement and progressive normalization of liver function. LESSONS: cGVHD is a multiorgan pathological condition, and this case emphasizes that a multidisciplinary team, including rheumatologists, should be involved in the follow-up of allo-transplant patients to ensure that the clinical complications are adequately addressed. Early intervention is critical for improving patient' prognosis.In addition, we performed a systemic literature review based on published case articles on hepatic cGVHD and digital ischemia published up to August 2022. To the best of our knowledge, this is the first reported case of such an association.

Clinical and histopathological evaluation of 50 acantholytic cutaneous squamous cell carcinomas: Analysis outcome in a retrospective case-control study.

BACKGROUND: Acantholytic cutaneous squamous cell carcinomas (aCSCCs) have been classically considered as a high-risk variant of CSCC. However, more recent studies show that aCSCC does not confer more aggressiveness. This study aims to establish whether the prognosis of the aCSCC is worse than that of the non-acantholytic (naCSCC) or not. METHODS: Retrospective case-control study with 50 aCSCCs and 50 naCSCCs. For each aCSCC, an naCSCC with similar high-risk features to the aCSCC but with no acantholysis was selected. Prognosis between both groups was compared. RESULTS: The mean age was 86 years (SD 9.61). Sixty-one patients were men. Thirty-nine CSCCs were located in high-risk head and neck areas. Twenty CSCCs exhibited a poor degree of differentiation, and 36 showed an infiltrative growth pattern. The tumor diameter was 18.71 mm (interquartile range, IQR 35), and the tumor thickness was 6.72 mm (IQR 15.50). Twelve CSCCs exhibited perineural infiltration, and eight CSCCs exhibited invasion beyond the subcutaneous fat. Positive margins after excision of the tumor in 22 aCSCCs vs eight naCSCCs (P < 0.02). Nineteen poor-prognosis events were observed (local recurrence, lymph node metastasis, and death from CSCC). However, no differences were observed between both groups when comparing poor-prognosis events. CONCLUSION: The proportion of unfavorable events is similar in aCSCC and naCSCC. The acantholytic histopathological subtype is not associated with a poorer prognosis than the non-acantholytic CSCC in our cohort.

Performance of Salamanca refinement of the T3-AJCC8 versus the Brigham and Women's Hospital and Tübingen alternative staging systems for high-risk cutaneous squamous cell carcinoma.

INTRODUCTION: The Brigham and Women's Hospital and the Tübingen cutaneous squamous cell carcinoma (SCC) stratification systems propose different criteria from the American Joint Committee on Cancer, eighth edition. Our group identified prognostic subgroups within T3 stage according to the American Joint Committee on Cancer eighth edition's classification, the most common classification for high-risk cutaneous SCCs. OBJECTIVE: To compare the performance and prognostic accuracy of these staging systems in a subset of high-risk cutaneous SCCs. METHODS: Homogeneity, monotonicity, and McNemar tests for pairwise comparisons were assessed. Distinctiveness and relative risk of poor outcome were calculated by stage. Prognostic accuracy was compared with respect to quality (Akaike and Bayesian information criteria), concordance (Harrell C-index and Gönen and Heller concordance probability estimate), and predictive accuracy (sensitivity, specificity, negative predictive value, positive predictive value, and global accuracy). RESULTS: The Brigham and Women's Hospital and Salamanca systems were more distinctive, homogeneous, and monotonic than the Tübingen system. The Tübingen system was the most specific, whereas the Salamanca and Brigham and Women's Hospital systems were more sensitive. Negative predictive value was high in all 3 systems, but positive predictive value and accuracy were low overall. CONCLUSIONS: Alternative staging systems may partially overcome the heterogeneity and low prognostic accuracy of the American Joint Committee on Cancer, eighth edition and enable high-risk cutaneous SCCs to be stratified more reliably, but their prognostic accuracy is still low. Considering the accumulation of risk factors may improve high-risk cutaneous SCC risk stratification.

Definition of prognostic subgroups in the T3 stage of the eighth edition of the American Joint Committee on Cancer staging system for cutaneous squamous cell carcinoma: Tentative T3 stage subclassification.

BACKGROUND: Although the eighth edition of the American Joint Committee on Cancer staging system (AJCC8) provides improved prognosis stratification of cutaneous squamous cell carcinoma (CSCC) over AJCC7, T3 has a variable prognosis. OBJECTIVE: To define prognostic subgroups in T3-AJCC8 CSCC. METHODS: Retrospective cohort study of 196 primary T3-AJCC8 CSCCs. We conducted multidimensional scaling analysis using the 6 risk factors that define T3 CSCCs. The prognoses of the groups obtained were analyzed by means of competing risk analysis. RESULTS: Group 1 was characterized by a tumor thickness greater than 6 mm (without invasion beyond the subcutaneous fat), alone or in combination with a tumor width of at least 4 cm. Group 2 was characterized by the presence of either invasion beyond the subcutaneous fat or by the involvement of nerves (≥0.1 mm, or deeper than the dermis). Group 3 was characterized by the combination of both T3b risk factors, or of 3 or more risk factors. Group 3 (tentatively named T3c) patients had the worst prognosis for disease-specific poor outcome events and major events, Group 2 (T3b) had intermediate risk, and Group 1 (T3a) had the best prognosis (disease-specific poor outcome events: hazard ratio [HR], 1.94; P = .00009; major events: HR, 2.55; P = .00001; disease-specific death: HR, 10.25; P = .0009). LIMITATIONS: Retrospective study. CONCLUSIONS: There is statistically significant evidence that T3-AJCC8 may be classified into distinct prognostic subgroups.

Programa Territorial de Detección precoz de Preeclampsia / Territorial Program for Early Detection of Preeclampsia

INTRODUCCIÓN En Argentina, el 15% de las muertes maternas son por Trastornos Hipertensivos. En la Región 7° de la prov. de Buenos Aires, el 8.2 % de las gestantes los presentaron. La implementación de programas de cribado de Preeclampsia durante el primer trimestre del embarazo detectan población con riesgo elevado. Las evaluaciones de este programa permite explorar la implementación, para adoptar políticas para la reducción de la Morbi- mortalidad materna/perinatal. OBJETIVO Evaluar la implementación de un programa de Screening de Preeclampsia en las semanas 11-14, en pacientes de Región 7° de la Provincia de Buenos Aires. MÉTODOS Investigación Traslacional en población obstétrica entre las 11-14 semanas derivadas al Hospital Posadas, al sector de Medicina Fetal. Aquellas con riesgo elevado fueron enviadas a consultorios de alto riesgo del centro de referencia donde se les indicó aspirina (<16sem.). Se capacitó a efectores para realizar el seguimiento hasta el nacimiento. Se consignaron datos del SIP de la región. Medidas de tendencia central y dispersiones/ medidas de frecuencia. RESULTADOS 275 screening completos. El 16% tuvo riesgo elevado de PE precoz y 29% riesgo de RCIU, presentando un 13.4 % ambos riesgos. Al análisis 109 personas gestantes finalizaron el embarazo, con 95% de seguimiento completo. El 90% de las pacientes con riesgo de PE precoz tomó aspirina a bajas dosis, y solo 5 pacientes presentaron el diagnóstico de PE. No hubo mortalidad materna y solo 1 caso, ­falso negativo en el screening presento PE con buena evolución. De los riesgos detectados de RCIU, hubo 2 casos que finalizaron el embarazo con RN nacidos vivos y sin complicaciones en su evolución neonatal. DISCUSIÓN A partir de la evaluación de este programa podemos observar una alta detección de PE, que permitió la intervención oportuna y el seguimiento de estas pacientes con impacto en su morbimortalidad.

Pseudolymphomatous Atypical Fibroxanthoma.

Atypical fibroxanthoma is a rare mesenchymal skin tumor of intermediate malignancy that typically occurs on sun-damaged skin of elderly patients. Histologically, it is composed of pleomorphic cells with hyperchromatic nuclei and abundant cytoplasm, commonly arranged in a spindle cell pattern. Different histologic variants have been described during the past years. We present a case of atypical fibroxanthoma containing a dense inflammatory infiltrate, which in conjunction with the existence of immunoblast-like and Reed-Sternberg-like neoplastic cells could be misinterpreted as a lymphoid neoplasm. Immunohistochemical studies revealed strong positivity of tumor cells for CD10 and negativity for cytokeratins, p63, p40, S100, SOX10, ERG, actin, desmin, B and T-cell markers, BCL6, CD15, and CD30. The inflammatory infiltrate contained a mixed reactive T- and B-cell population with negative T-cell receptor and immunoglobulin heavy rearrangements. We discuss the differential diagnosis of this entity in which clinical, immunohistochemical, and molecular features are essential to avoid the diagnosis of a lymphoproliferative disease.

[Maternal mortality. Hospital Profesor Alejandro Posadas, Buenos Aires. Evolution 2003-2015]. / Mortalidad materna. Hospital Profesor Alejandro Posadas, Buenos Aires. Evolución 2003-2015.

We reviewed the medical records of women with maternal death reported from August 2003 to December 2015 in the Posadas Hospital (Buenos Aires Province, Argentina), and calculated indexes, trends and years of potential life lost. A total of 52 cases fulfilled the criteria of maternal death. The information provided by death certificates was meager. Two deaths were incidental: one occurred post-caesarean section and was caused by fat embolism following liquid silicone breast injection, and the other was the consequence of femicide which involved also the 24-week fetus. Of the remaining 50 cases, 11 were late deaths (> 42 days postpartum). In 39 women, death occurred during pregnancy, childbirth, or puerperium up to 42 days: 20 were due to direct obstetric causes, and 18 to indirect, non-obstetric causes, the cause of the remaining death was not determined. The most frequent cause was septic abortion. Direct maternal deaths had had more than twice pregnancies, thrice caesarean sections, and orphaned twice as children as indirect deaths. Death caused by placenta accreta was directly related to the number of previous caesarean sections. Throughout the period, maternal mortality index varied between 25 y 150 (mean: 72) per 100 000 live births with ascending trend and 1576 years of potential life were lost. The study exposes the need to improve the death registration system and, most importantly, strengthen prevention and assistance measures to reduce maternal mortality in the area of influence of our hospital.

Revisamos las historias clínicas de las mujeres cuyo fallecimiento fue notificado como muerte materna entre agosto de 2003 y diciembre de 2015 en nuestro hospital y calculamos índices, tendencias y años de vida potencialmente perdidos. La información aportada por los certificados de defunción fue exigua. Un total de 52 casos cumplía con los criterios de muerte materna. Dos fueron muertes "incidentales" y dejaron siete huérfanos: una fue causada por embolia grasa por inyección de siliconas en mamas post-cesárea y la otra fue consecuencia de un femicidio que incluyó al feto de 24 semanas. De las 50 muertes maternas restantes, 11 fueron tardías (> 42 días post-parto). Las otras 39 ocurrieron durante el embarazo, parto y puerperio (= 42 días): 20 tuvieron causas obstétricas directas, 18 causas indirectas, y la causa de la restante fue indeterminada. La causa más frecuente de muerte fue el aborto séptico. Las muertes maternas directas presentaron como antecedentes más del triple de cesáreas y el doble de gestas que las indirectas, y dejaron el doble de huérfanos. La muerte por placenta accreta tuvo relación directa significativa con el número de cesáreas. El índice de mortalidad materna total varió entre 25 y 150 (media: 72) por 100 000 recién nacidos vivos en el período, con tendencia ascendente. Los años de vida potencialmente perdidos fueron 1576. Se destaca la necesidad de mejorar el sistema de registro de defunción y reforzar las medidas de prevención y asistencia a fin de disminuir la mortalidad materna en el área de influencia del hospital.

Cutaneous collagenous vasculopathy: papular form.

Cutaneous collagenous vasculopathy is a rare clinicopathological entity, first described in 2000. Cutaneous collagenous vasculopathy has been considered a form of microangiopathy of superficial dermal vessels and produce lesions that appear as telangiectasia. We present a patient with histopathologic features of cutaneous collagenous vasculopathy and scattered erythematous papules on the trunk with a striking dermatoscopic finding. We propose the term of 'cutaneous papular collagenous vasculopathy' as a new clinical manifestation of this disease.

Tendencia de edad gestacional y cambios en la práctica obstétrica en un período de 10 años / Gestational age trend and changes in obstetric practice in a period of 10 years

Introducción: La edad gestacional, definida como semanas de gestación completas, es el principal predictor de resultados perinatales. El monitoreo de las tendencias en la distribución de la edad gestacinal puede ser un indicador importante de los resultados de salud y desarrollo a largo plazo. Objetivos: Primario: Examinar la tendencia de la edad gestacional de los partos asistidos en el Servicio de Obstetricia del Hospital Nacional A. Posadas durante el período comprendido entre 2008-2017. Secundarios: Evaluar la tendencia en la edad gestacional según forma de inicio del parto. Determinar vía de finalización del embarazo según edad gestacional. Establecer complicaciones perinatales asociadas a la edad gestacional. Material y Métodos: Estudio observacional descriptivo y transversal. El relevamiento de datos se realizó a través del SIP. Criterio de inclusión: edad gestacional igual o mayor a 37 semanas. Criterios de exclusión: faltante de datos para la variable principal de interés. Las variables se presentan a través de medidas de frecuencia (%). Las comparaciones se realizaron con test Chi cuadrado/Fisher exact test según la conformación de la tabla de doble entrada. Se consideró un p valor<=0.05. Stata 12.0 Resultados: Durante el período de estudio se registraron 38977 nacimientos, de los cuales 28835 cumplieron con los criterios de inclusión. El mayor porcentaje de nacimientos se produjo a las 39 semanas, variando entre 27% (2008) y 35% (2016). Se encontró una disminución gradual de los nacimientos a las 40 semanas, siendo de 12% en 2008 y 6% en 2017. La edad gestacional más frecuente de finalización programada, hasta el 2014 la edad gestacional más frecuente fue 38 semanas (25%-33%) y a partir del 2015 se postergó a las 39 semanas (29%-37%). En cuanto a la vía de finalización, la prevalencia de partos vaginales fue mayor en todas las semanas, aumentando la frecuencia a mayor edad gestacional (p=0.001). Al analizar las complicaciones perinatales se encontró que la tasa de mortalidad perinatal fue en disminución hasta las 39 semanas, con una diferencia mayor a menor edad gestacional al comparar nacimientos programados y espontáneos (24.5%00 vs 13%00; 13%00 vs 7%00; y 4%00 vs 3%00 a las 37, 38 y 39 semanas respectivamente). El 39% de los nacimientos producidos a las 37 semanas de modo programaado requirieron ingreso a terapia intensiva neonatal, disminuyendo a 19% a las 38 y 14% a las 39 semanas. Conclusión: La distribución de la edad gestacional al término del embarazo ha cambiado en los últimos 10 años a expensas de un aumento de la finalización espntánea a las 39 semanas y a un cambio en la práctica obstétrica con respecto a la postergación de una semana en la finalización programada en aquellas mujeres con patologías materno fetales o cesáreas iterativas. Este cambio constribuye a disminuir la morbimortalidad perinatal ya que fue observado que a menos edad gestacional aumentó el ingreso a terapia intensiva neonatal luego del nacimiento programado, así como también contribuye a la disminución del gasto en salud (AU)

This article details trends of the gestational age and changes in the obstetrical practice during a 10 yr, period. We can define gestational age as weeks of complete gestation, as the main predictor of perinatal results. The monitoring of the trends in the distribution of the gestational age can be an important indicator of the results of the health and development in a long term. Objectives: Primary: to examine the tendency of the gestational age of the deliveries attended in our Hospital between 2008-2017. Secondary to evaluate the tendency of the gestational age according to the start of the delivery. To determine the route of ending of the pregnancy according to the start of the delivery. To determine the route of ending of the pregnancy according with the gestational age. To establish perinatal complications associated to the gestational age. With this study it is proposed to evaluate the tendency to the gestational age at the birth, in a 10-yr. period in our institution and if changes in the obstetric practice in that period influenced in it. In conclusion, the results obtained in this investigation, justify the change of behaviour in the programmed ending of the pregnancy, contributing to the decrease of the perinatal morbi-mortality, and in consecuence, to the diminishing of the waste in health (AU)

Experiencia en la colocación del DIUPP / Experience in the placement of the Diupp

Family planning is a key intervention to decrease the mortality rates and maternal morbidity, and neonatal mortality rates of children by mean of the preventiion of unwanted pregnancies, the same as pregnancies that happen very clsely to another previous one with little space between them. Several studies performed in different parts of the world have demonstrated adverse results related specially with the spaciament of the pregnancies. The risks are particularly higher with women wich get pregnant les after than a previous deliver, spontaneous abortion or induced abortion. The instrauterine device (ID) is a family planning higly efficacious with a prolongued action and reversible, that offers security to most postpartum women, including those who are still nursing. The primary aim of the present report was to determine the frequency in the placement of the DIUPP in our Obstetrical Department between 01/06/2017 and 30/06/2018, and in a second instance, to describe the method for placement of the DIUPP, to determine the curve of learning, to measure the rate of expulsion of the device, and to evaluate the conformity of the users of the method. Unplanned pregnancies have strongly increased, and for that circumstance, we believe that with new strategies, such as it is with the post-event anticonception, we can improve the reproducive health (AU)

Intervenciones diagnósticas prenatales en un hospital público / Prenatal diagnostic interventions in a public hospital

The authors present a study of prenatal diagnostic interventions in a public hospital. The invasive prenatal diagnosis can be achieved by means of threee methods, aspirative punction of chorionic villous, extraction of amniotic fluid and fetal blood sample. Samples of chorionic villus are empoyed for citogenetic study, determination of the fetal cariotype or realization of a specific determination through technic FISH (Fluorescence in situ hybridization) or molecular genetics. Sample of amniotic fluid consists in the aspirative puncture under direct sonographic control of the amniotic cavity. During the period of the study, 9457 obstetric sonographies were performed with 121 genetic consultations of whom 46 resulted in invasive prenatal diagnostics. The results obtained are discussed (AU)

A New Case of Schindler Disease.

Lysosomal storage disorders (LSDs) are a group of genetic disorders caused by mutations in genes encoding enzymes involved in lysosomal function. Schindler disease is an autosomal recessive, inherited LSD caused by defective or non-existent activity of the enzyme α-N-acetylgalactosaminidase (α-NAGA). To date, three main phenotypes of Schindler disease have been described. We report the case of a 68-year-old man presenting with axonal and demyelinating polyneuropathy, sensorineural hearing loss, chronic lymphoedema, angiokeratoma corporis diffusum and bilateral carpal tunnel syndrome. Genetic testing (PCR) for α-galactosidase revealed the c.577G>T (p.Glu193*) mutation in the NAGA gene, confirming Schindler disease, which is clinically compatible with Kanzaki disease and Schindler disease type II. LEARNING POINTS: Schindler disease is a very rare lysosomal storage disorder.To our knowledge, fewer than 20 cases have been described to date.Consequently, each new case should be reported to enhance understanding of the wide range of presentations.

Comparing the eighth and the seventh editions of the American Joint Committee on Cancer staging system and the Brigham and Women's Hospital alternative staging system for cutaneous squamous cell carcinoma: Implications for clinical practice.

BACKGROUND: The new eighth edition of the American Joint Committee on Cancer staging system (AJCC-8) incorporates changes regarding cutaneous squamous cell carcinoma (CSCC). OBJECTIVES: We aimed to compare the AJCC-8 staging system with the previous seventh edition of the AJCC staging system (AJCC-7) and the Brigham and Women's Hospital (BWH) alternative staging system to identify their usefulness and the utility of their risk factors in defining prognostic groups in CSCC. METHODS: A series of 186 CSCCs of the head and neck were retrospectively collected. All 3 staging systems were compared from the standpoint of their ability to predict poor prognosis. Binary logistic regression models were built to determine which risk factors were most relevant. RESULTS: Poor prognosis was mainly associated with stage T2 of the AJCC-7, with stages T2b/T3 of the BWH system, and with stage T3 of the AJCC-8. The AJCC-8 and the BWH staging systems displayed overlap with each another in predicting poor prognosis, and both were superior to the AJCC-7. The new risk factors incorporated into the AJCC-8 and the poor degree of differentiation were independently associated with poor outcome. LIMITATIONS: Retrospective study and few cases with bone invasion. CONCLUSIONS: The AJCC-8 is more distinctive, monotonous, and homogeneous than the AJCC-7 and shows some overlap with the BWH system in stratification of tumors.

Near Miss: un indicador de calidad en los servicios de obstetricia / NEAR MISS: INDICATOR OF HIGH QUALITY CARE AT OBSTETRICAL SERVICES

Introducción: Near Miss (NM) o complicación materna aguda grave (CMAG), ocurre en una mujer que durante el embarazo, el parto o dentro de los 42 días posteriores a la finalización del embarazo tiene una complicación grave que la lleva a estar cerca de la muerte, pero sobrevive. Representa un mejor indicador de salud a medida que la muerte materna (MM) disminuye. Objetivo: Estimar la incidencia de los casos con CMAG, según criterios de la OMS, en el Servicio de Obstetricia del Hospital Nacional Prof. Dr. Alejandro Posadas desde 1 de agosto de 2014 al 31de julio de 2015. Resultados: Hubieron 3293 nacimientos en el servicio de obstetricia en el periodo de estudio, 20 mujeres presentaron CMAG, con uno o más criterios de elegibilidad de la OMS. Las muertes maternas (MM) en el mismo periodo fueron 4. La incidencia de CMAG fue de 0,6%. El promedio de edad fue de 27 años +/- 7, el 30% (6) eran nulíparas, el 30%(6) fueron derivadas de otra institución. La complicación severa, se presentó en un 75% durante el embarazo. Sus causas fueron: Hemorragia 30% (6), HTA 20% (4), causas respiratorias 20% (4), neurológicas 10%(2), infecciosas 5% (1) y metabólicas 10% (2), HTA y hemorragia 5%(1). La OMS clasifica los criterios de NM para determinar la insuficiencia orgánica en: clínicos, de laboratorio y terapéuticos. El 55% presentó 2 criterios, 35% 1 criterio y 10% los tres criterios. Se finalizó el embarazo en 18 pacientes, por cesárea en el 83,3% (15) y cesárea + histerectomía en 16,6% (3). Dos mujeres continúan con su embarazo. Respecto a los resultados perinatales, hubieron 3 fetos muertos y 1 embarazo gemelar, la EG promedio de los recién nacidos fue de 32+/-5 y la media de peso fue de 1865 +/- 1073 y su mediana de 1620gr (25% 850 y 75% 2535). Se calcularon los siguientes indicadores: Mujeres con enfermedades potencialmente fatales (MEPF): CMAG+MM: 24; Razón de complicaciones maternas agudas graves= CMAG/NV(x 1000 Nacidos Vivos)= 6,1/00; Razón morbilidad materna severa: RMMS: CMAG / MM = 5:1; Índice Mortalidad Materna: IMM: MM / MM +CMAG X100= 16,7% Conclusiones: El análisis de las Complicaciones Maternas Agudas graves podría usarse como indicador de calidad del cuidado materno, mejorando el sistema de vigilancia, con la cual se podría reducir la tasa de Mortalidad Materna

"Near Miss" or severe acute life-threatening maternal complication (SAMC) occurs in woman that during the pregnancy, the delivery or within the 42 days following the end of their pregnancy, has a severe complication that situates her closely to death, but contrarily survives. It represents the best indicator of health according to the decreasement of maternal deaths. The objective of this study was to estimate the incidence of cases of SAMC according to the WHO,in the Service of Obstetrics from the National Hospital "A. Posadas" between August 1° to July 31st. 2015. Results : there were 3293 deliveries in the Obstetrical Service during the period studied, of whom 20 women presented SAMC, with one or more elegibility criteria of the WHO. Maternal deaths (MD) during the same period reached 4 cases. The incidence of SAMC was 0,6 %. The mean age was 27 years +/- 7, being 30 % nulliparous,and 30 % were derivated from other institution. The severe complication was presented in 75 % during the pregnancy. Their causes were: Hemorrhage 30 % (6), AHT 20% (4), respiratory causes 20% (4), neurological 10% (2), infectious 5% (1) and metabolic 10% (2), AHT and hemorrhagic 5% (1). The WHO classifies NM criteria to determine the organic insufficiency in: clinical, from laboratory and therapeutical. 55% presented 2 criteria, 35 % 1 criterion and 10 % all three criteria.The pregnancy ended in 18 patients, by cesarean section in 83.3% (15) and cesarean + hysterectomy in 16,6% (3). Two women continue with their pregnancy. In relation with the perinatal results, 3 produced a death fetus and in 1 case a twin pregnancy, the mean EG of the newborns was 32+/- and the mean weight was 1865 +/- 1073 and their median was 1620 gr (25% 850 and 75% 2535 ). The following indicators were calculated : Women with potentially fatal diseases 24; (SAMC + MD), Reason of severe acute maternal complications = SAMC/BA (x 1000 Born Alive) = 6,1/00; Reason of severe maternal morbidity RSMM: SAMC/ MM = 5:1; Rate of Maternal Mortality: RMM: MM/MM + SAMC x 100= 16,7%. Conclusions: analysis of the severe acute maternal complications could be used as an indicator of quality for the maternal care, improving the vigilance system, by which the rate of Maternal Mortality could be reduced.
