Programa de transición: una intervención para adolescentes con diabetes tipo 1: estudio de casos y controles / Transition program: an intervention for adolescents with type 1 diabetes: cases and controls study

Introduction: The transition programs (TP) are planned interventions with specific aims which support type 1 diabetes adolescents in their process to emigrate from a pediatric care system to an adult care system. Objective: To evaluate the effectiveness of a TP in type 1 diabetes adolescents. Subjects and Method: This study was performed in 20 adolescents: 10 in TP and 10 controls (no TP) attended in an adult care system in a traditional way. The applied program included: coordination of attention dates, administrative supervision of the cases, and integral health team attention: physician every three months, psychologist with psychosocial follow-up every three months, nutricionist and university nurse according to the case necessities. After a year of the TP implementation the indicators of adherence were evaluated: continuity of care, regular medical appointments, physician/adolescent relationship, psychosocial follow-up, and to maintain or improve the HbA1c. The statistical analysis of variables comparison was performed with Kwallis Test o Mann-Whitney Test, in STATA 12.0 program. Results: At comparing groups, it was found that the intervened adolescents presented a major frequency of: continuity of diabetes care, regular medical appointments, physician/adolescent relationship and psychosocial follow-up (p < 0,01); the indicator of maintaining or improving the HbA1c was better in the patients with TP (60 percent vs 30 percent) yet not significant. Conclusion: In type 1 diabetes adolescents, with the applied TP we get better indicators of adherence to the diabetes treatment

Fractura aislada de pared medial de órbita / Isolated orbital medial wall fracture

Abstract Background: Orbital floor fractures are a common finding in facial trauma and may be accompanied by medial orbital wall fracture in 7 to 53% of the cases. Isolated medial wall fractures are rare and usually asymptomatic, being detected as incidental findings. case report: We report a 75 years old female consultingin the emergency room due to a left orbital trauma. An orbital CAT scan identified a fracture of the medial orbit wall that did not require treatment.

Resumen Introducción: Las fracturas del suelo de la órbita son habituales en los traumatismos faciales y entre un 7 y un 53% de los casos se asocian con fracturas de la pared medial. Pero las fracturas aisladas de la pared medial son infrecuentes y la mayoría asintomáticas, siendo un hallazgo habitualmente incidental. Sin embargo, ciertos signos de alarma (limitación de la movilidad del recto medial, siendo habitual que aparezca de forma retardada por isquemia del músculo debido al atrapamiento) pueden plantear una cirugía urgente. Descripción del caso: Presentamos un caso de una paciente de 75 años que acude al Servicio de Urgencias de nuestro hospital remitida por médico de atención continuada por traumatismo sobre órbita izquierda. A la exploración presenta importante hematoma periorbitario y malar, sin alteraciones visuales. En TC orbitaria se identifica fractura de la pared medial de la órbita que, en ausencia de clínica acompañante, no requiere tratamiento alguno.

Metformina asociada a insulinoterapia en pacientes diabéticos tipo 1 / Metformin associated with insulin therapy in type 1 diabetic patients

In patients with diabetes type 1 (T1D) glycemic control remains suboptimal, despite the availability of new insulin analogues and continuous infusion systems. Metformin may be a complementary therapy regarding to intensified insulin therapy since a significant percentage of T1D have insulin resistance (IR). Objective: To analyze the clinical, anthropometric and metabolic effects of the combination of metformin to insulin therapy in T1D patients. Subjects and Method: 34 T1D patients, 15 men and 19 women, mean age 41 years (range 20-64) metformin 850 mg / day was associated for 6 months (group 1) and retrospectively evaluated 18 T1D, 9 men and 9 women, age average 34 years (range 17-58), who received metformin for 36 months (group 2). It was recorded before and after treatment with metformin: nutritional status, waist circumference, index waist / hip, glucose fasting, glycosylated hemoglobin (HbA1c), HDL cholesterol, triglycerides, systolic and diastolic blood pressure (BP), glucose uptake (UG) and insulin dose (U/kg). Statistical analyses. Clinical and biochemical parameters were expressed as median, range or percentage (percent). For the statistical significance were used chi2and Fisher exact and Mann Whitney test; and was established as significant at p <0.05. Results: In group 1 significantly decreased waist circumference in men and women and improved fasting glucose, HbA1c, systolic blood pressure and triglycerides. In group 2, waist circumference and systolic blood pressure was also reduced. Conclusion: In T1D patients with clinical signs of IR the association of metformin to insulin therapy may be useful.

Programa de diagnóstico y tratamiento fetal. Estudio de cohorte sobre su efectividad en la evolución de neonatos con patologías quirúrgicas / Program for prenatal diagnosis and treatment: A cohort study on effectivity on the outcome of newborns with surgical pathologies

Introducción. El diagnóstico prenatal de las malformaciones congénitas (MC) permite optimizar el cuidado perinatal. Al Hospital Garrahan (HG) ingresan recién nacidos (RN) con MC para tratamiento quirúrgico. Desde el año 2008 funciona el programa de diagnostico y tratamiento fetal (PDTF) para optimizar el cuidado prenatal y perinatal de RN con MC. El objetivo del estudio es evaluar el impacto de la derivación prenatal en RN que ingresan a la unidad de cuidados intensivos neonatales (UCIN) del HG por MC seleccionadas. Población y Métodos: estudio observacional analítico y comparativo entre grupos, sobre condición de ingreso y evolución de RN con gastrosquisis (GTQ), mielomeningocele (MMC) y hernia diafragmática (HD) y grado de stress parental, según ingreso a UCIN por derivación prenatal o postnatal. Se realizó análisis bivariado, descriptivo y comparativo de indicadores generales y especiales de cuidado. Resultados: Se incluyeron 164 RN (44 con derivación prenatal a través del PDTF). Este grupo presentó: mejor control del embarazo (93% vs 66%, p: 0.04), menor edad gestacional al diagnóstico (24s vs 33s p=0.0006) y mayor tasa de cesárea electiva (95 vs 47%, p=0.0001). Los RN tuvieron menor necesidad de reanimación e ingresaron más tempranamente a la Unidad (mediana 4hs vs 10hs, p=0,004). Hubo menor stress parental en relación al hijo (17 vs 40%). Los RN con GTQ ingresaron mejor curados y se alimentaron por vía enteral más rápidamente. Conclusión: Los RN con MC derivados prenatalmente a través del PDTF, ingresan precozmente y presentaron mejores estrategias de cuidado que los ingresados por derivación habitual (AU)

Introduction. Prenatal diagnosis of congenital malformations (CM) improve perinatal care. At the Garrahan Hospital (GH) newborns (NB) with CM are admitted for surgical treatment. Since 2008 a program for prenatal diagnosis and treatment (PDT) has been in place to optimize prenatal and perinatal care of NB with CM. The aim of this study was to assess the impact of prenatal referral of NB that are admitted to the GH for selected CM. Population and Methods: An observational, analytical, and between-group comparative study was conducted on the status on admission and outcome in NB with gastroschisis (GS), myelomeningocele (MMC), and diaphragmatic hernia (DH) and degree of parental stress, according to NICU admission after prenatal or postnatal referral. Bivariate, descriptive and comparative analysis of general and specific markers of care was performed. Results: 164 NB were included (44 were prenatally referred through the PDT program). The latter group presented with better pregnancy control (93% vs 66%, p: 0.04), younger gestational age at diagnosis (24w vs 33w p=0.0006), and higher rate of elective cesarean section (95 vs 47%, p=0.0001). This group of NB needed less reanimation and were admitted to the NICU earlier (∑4hs vs 10hs, p=0.004). Parental child-related stress was less (17 vs 40%). NB with GS had a better surgical outcome and were started on enteral feeding earlier. Conclusion: NB with CM that were prenatally referred through the PDT program, were admitted earlier and could be managed with better strategies than those who were conventionally referred (AU)

Diabéticos tipo 1 portadores de síndrome metabólico: cuantificación de la resistencia a la insulina / Type 1 diabetics patients carriers of metabolic syndrome: quantification of insulin resistance

The presence of insulin resistance (IR) has been indirectly assessed in Type 1 Diabetics (T1DM) through the detection of Metabolic Syndrome (MS), by applying criteria for Type 2 Diabetics(T2DM). In the EDC study (the Pittsburg Epidemiology of Diabetes Complications) a formula applicable to T1DM was validated, quantifying IR through the glucose uptake (GU) employing the usual clinical and laboratory parameters, in patients with HbA1c < 11.4 percent. Objectives: To determine in T1DM whether there exists a relationship between the presence of MS according to the Modified NCEP/ATPIII criteria and IR quantification through assessment of the glucose uptake or GU. Patients and Method: The modified NCEP/ATPIII criteria were applied to 150 T1DM patients, and those with more than 3 altered parameters were classified as MS carriers. IR was quantified through the glucose uptake (GU), applying the formula for Estimated Glucose Disposal Rate (GDR-EDC). Results: 26.6 percent of the T1DM (40 patients) complied with the modified NCEP/ATPIII criteria. When the formula for GU was applied (31 patient), 90.3 percent of the T1DM showed insulin resistance (GU value < 8.77). And when applied to 124 patients (T1DM with and without MS and HbA1c < 11,4 percent) 75 percent showed IR...

Hiperplasia pseudoangiomatosa nodular gigante de la mama / Pseudoangiomatous stromal hyperplasia (pash) of the breast

La hiperplasia pseudoangiomatosa (PASH) es una lesión proliferativa benigna de la mama, poco frecuente, caracterizada por la existencia de lagos pseudovasculares embebidos en una gran proliferación del estroma mamario. Probablemente, el desarrollo de la PASH tenga una influencia hormonal, por lo que típicamente se diagnostica en mujeres en edad fértil. La PASH es un hallazgo histopatológico casual en las piezas quirúrgicas y biopsias mamarias realizadas por otra patología. La presentación clínica en forma de masa palpable es poco frecuente. El principal diagnóstico diferencial debe realizarse con el angiosarcoma de bajo grado. El tratamiento de la PASH nodular es una correcta exéresis quirúrgica asegurando borde sano amplio. El pronóstico es excelente, con un mínimo riesgo de recidiva si se realiza una adecuada cirugía. Se presenta el caso de una mujer de 37 años que acude a consulta por un nódulo mamario de crecimiento rápido.

Pseudoangiomatous stromal hyperplasia (PASH) of the breast is a rare benign proliferative mesenchymal lesion characterized by the presence of open slit like spaces embedded in a hyalinized fibrous stroma. The development of PASH is probably subject to hormonal influence so it typically affects women in the reproductive age group. Pseudoangiomatous stromal hyperplasia is frequently an incidental histologic finding in breast surgeries or biopsies performed for other injuries. In rare cases, it presents as a localized breast mass. The most important differential diagnosis is low-grade angiosarcoma. Tumorous PASH is treated by local surgical excision with clear margins. The prognosis is excellent, with minimal risk of recurrence after adequate surgery. The presented case was a 37-years-old woman who was admitted with a rapidly growing breast tumor.

Neoplasia vaginal intraepitelial / Vaginal intraepithelial neoplasia

Objetivo: actualizar los conocimientos disponibles sobre la neoplasia vaginal intraepitelial (VAIN) especialmente en el diagnóstico y tratamiento. Métodos: revisión de la literatura en Pubmed de los últimos 20 años, especialmente de los publicados desde 2005 hasta la actualidad y considerando sobre todo los ensayos clínicos aleatorizados. Resultados: su prevalencia real es desconocida, aunque es una patología rara generalmente en mujeres posmenopaúsicas. Su fisiopatología es similar a la neoplasia cervical intraepitelial, con el HPV como principal factor de riesgo, sobre todo el serotipo 16, pero su progresión a cáncer es menor. Un grupo importante es el de VAIN tras histerectomía, que supone el 48-70 por ciento del total de las VAIN. La colposcopia para el diagnóstico no es sencilla y se aconseja preparación con estrógenos en las pacientes menopáusicas y utilización de ácido acético y lugol para identificar las zonas sospechosas. Las tres opciones terapéuticas son la cirugía (excisional, láser, ultrasonidos), braquiterapia y tratamiento médico (imiquimod, 5-fluorouracilo, ácido tricloroacético). Se expone la técnica y las ventajas e inconvenientes de cada uno de ellos. Conclusión: aunque la VAIN es una entidad rara, es preciso tenerla en cuenta ante un diagnóstico de lesión citológica. Su diagnóstico a veces no es sencillo y el tratamiento dependerá del grado, la localización y el tamaño de la lesión y las circunstancias personales de la paciente. Se necesitan más ensayos aleatorizados que comparen la eficacia entre las distintas opciones terapéuticas y su repercusión en la calidad de vida de las pacientes.

Aims: update the knowledge about vaginal intraepithelial neoplasia (VAIN) with special emphasis on diagnosis and therapeutic management. Method: electronic search of Pubmed of all kinds of articles about the VAIN, for the last 20 years with special attention to those published from 2005 to the present and considering especially randomized clinical trials. Results: its prevalence is unknown, although it is a rare condition that usually occurs in postmenopausal women. The physiopathology is similar to cervical intraepithelial neoplasia, being HPV the main risk factor, particularly serotype 16, but its progression to cancer is lower. An important group is VAIN after hysterectomy, 48-70 percent of total VaIN. Colposcopy for the diagnosis is not easy and in patients with postmenopausal the preparation with local estrogen is necessary and use both of acetic acid and lugol to identify suspicious areas. The three treatment options are surgery (excisional, laser, ultrasound), brachytherapy and medical management (imiquimod, 5-fluorouracil, tricholoroacetic acid). The technique and the advantages and disadvantages of each are explained. Conclusion: although VAIN is rare, it must take it into account before a cytological diagnosis of dysplasia. Its diagnosis is sometimes not easy and the treatment depends on the extent, location and size of the lesion and the individual preferences of the patient. We need more randomized trials comparing different treatment options and also their impact on quality of life of patients.

Rabdomiosarcoma embrionario de cérvix uterino en mujer adulta / Embryonal rhabdomyosarcoma of uterine cervix in adult female

El rabdomiosarcoma (RMS) del tracto genital inferior es una patología maligna relativamente frecuente en la infancia aunque muy poco prevalente en la edad adulta. Tan solo suponen el 2-4 por ciento de todos los sarcomas de partes blandas. Se trata de una neoplasia derivada de células progenitoras de miocitos de músculo estriado en distinto grado de diferenciación. En un elevado número de casos, el cuadro se presenta como un pólipo endocervical de apariencia benigna, lo cual retrasa el diagnóstico. El correcto manejo del RMS de tracto genital es controvertido. Un esquema agresivo de tratamiento con cirugía, poliquimioterapia y radioterapia en pacientes seleccionadas, ha demostrado aumentar la supervivencia e incluso conseguir la curación en estadios precoces.

Rhabdomyosarcoma (RMS) of the lower genital tract is a common childhood malignancy but a rare tumor in female adults. It accounting for around 2-4 percent of soft-tissue sarcomas. It is a malignant neoplasm originating from myogenic progenitors cells that shows variable stages of skeletal muscle differentiation. In many cases, the tumor appears as a benign endocervical polyp and this delays the correct diagnosis. Optimal management of adult genital tract RMS is uncertain. Aggressive primary therapy with local excition, poliche-motherapy and radiotherapy in selected patients may result in prolonged survival and cure in early stages.

Úlcera genital aguda en paciente adolescente / Acute genital ulcer in an adolescent patient

La úlcera vulvar aguda o úlcera de Lipschütz es una entidad poco frecuente y habitualmente subdiagnosticada. Es reconocida por la aparición súbita de lesiones ulcerosas y dolorosas en vulva, vagina y/o periné, sin antecedente de contacto sexual previo. La etiología es desconocida. El diagnóstico diferencial debe incluir causa infecciosa venérea o no, síntoma de cuadro autoinmune u otra enfermedad sistémica, o efecto secundario a la administración de fármacos. Las lesiones desaparecen espontáneamente, habitualmente sin secuelas y sin recurrencias a largo plazo.

Acute genital ulcer or Lipschütz ulcer is a rare and underdiagnosed, entity that usually presents an acute and painful ulcer in the vulva, lower vagina and/or perineum of nonvenereal origin. The etiology is unknown but the differential diagnosis must include sexually and nonsexually transmitted infections, autoimmune conditions, local manifestations of systemic illness and drug reactions. The lesions heal spontaneously and most patients have no recurrence and no long-term sequelae.

Adenocarcinoma de endometrio de patrón sertoliforme / Sertoliform carcinoma of the endometrium

Se presenta el caso de una paciente que consultó por metrorragia posmenopaúsica. En la biopsia histeroscópica dirigida se informó de adenocarcinoma de endometrio endometrioide bien diferenciado. Se practicó histerectomía, doble anexectomía y lavados peritoneales. Durante el acto quirúrgico se valoró el grado de infiltración miometrial, que al revelar afectación del útero hasta la serosa, implicó la realización de linfadenectomía de espacios pélvicos y paraaórtico. El diagnóstico definitivo anatomopatológico fue de adenocarcinoma de endometrio tipo endometrioide de patrón sertoliforme moderadamente diferenciado. El estadío FIGO fue IIIA, por lo que se indicó quimioterapia y radioterapia como tratamiento adyuvante. A los 2 años la paciente presenta recidiva ganglionar y metástasis pulmonares con progresión a pesar del tratamiento quimioterápico, por lo que finalmente fallece.

We report a case of a patient with postmenopausal bleeding. In hysteroscopic directed biopsy was reported endometrioid endometrial adenocarcinoma well differentiated, so that she underwent total hysterectomy, both salpingo-oophorectomy and peritoneal washings. In the surgery, we evaluated the miometrial infiltration, with report invasion until serosa, so we practised pelvic and paraaortic lymphadenectomy. The pathologic diagnosis was sertoliform endometrioid carcinoma of the endometrium with moderate differentiation. The FIGO stage was IIIA, and we indicated chemotherapy and radiotherapy. Two year after, the patient presented nodal recurrence and lung metastases with no response to the chemotherapy drugs, so she dies.

Fascitis necrotizante en recien nacidos / Necrotizing fascitis in newborns

La fascitis Necrotizante (FN) es una emergencia quirúrgica, resultado de la infección de los tejidos subcutáneos y de la fascia superficial, por una gran variedad de bacterias. En esta etapa neonatal, esta afección puede alcanzar una mortalidad mayor al 70 por ciento. El éxito del tratamiento requiere un preciso diagnóstico y precoz y agresivo desbridamiento de los tejidos afectados, la cobertura por vía parenteral de antibióticos de amplio espectro y un soporte adecuado en cuidados intensivos. Reportamos un caso de FN en recién nacidos de sexo masculino, en quien la enfermedad se desencadenó probablemente luego de una onfalitis. Este reporte ilustra la naturaleza devastadora de este tipo de infección, sin embargo, con tratamiento agresivo y precoz es posible lograr resultados satisfactorios.

Prevalence of Helicobacter pylori at antral mucosa of patients with dyspepsia at University District Hospital

A total of 120 patients with dyspepsia were evaluated by endoscopy to determine the prevalence of Helicobacter pylori in the gastric antrum in 1988. It was found that duodenal ulcer and gastric ulcer were highly associated with this bacteria. Also statistically significant association between H.p. and active gastritis was observed

Prevention of recurrent esophageal bleeding and survival in patients with alcoholic cirrhosis: a randomized study

OBJECTIVES: To compare endoscopic sclerotherapy, propranolol and distal splenorenal shunt in the prevention of rebleeding esophageal varices and mortality in alcoholic cirrhotics. METHODS: Forty-three alcoholic cirrhotics that had bled from esophageal varices were randomized to sclerotherapy (13), shunt (15) or propranolol(15). Outcomes measured were rebleeding from varices and death. RESULTS: There was no significant difference between the three treatment groups in relation to rebleeding rate or death. Continued alcohol consumption did not influence outcome. CONCLUSIONS: All three therapies were equally effective in preventing rebleeding from varices

Marco teórico y conclusiones de la investigación sobre violencia estructural

El concepto de violencia estructural supone analizar dos aspectos: el de la violencia en sí misma, y el de su caracter estructural. El concepto de violencia será estudiado tomando en cuenta dos definiciones: la que aporta Galtung, y la que existe en el informe preparado por la Comisión del Senado de la República Peruana sobre Violencia y Planificación. Haremos, finalmente, algunas distinciones de conceptos vinculados a ella
