Atypical presentation of Gorham-Stout syndrome. Case report

Gorham-Stout syndrome is an extremely rare pathology, of unknown etiology. It is characterized by proliferation of vascular channels that causes destruction and reabsorption of the bone matrix. We present a nine year-old male patient with an acute episode characterized by fever, chest pain, respiratory distress and dyspnea. The patient was submitted to computed tomography scan and a biopsy. The findings in the biopsy were multiple lytic lesions, osteolysis, and a mediastinal lymphangioma (lymphangiomatosis). The diagnosis was Gorham-Stout syndrome with atypical presentation

Characterization of two Achromobacter xylosoxidans isolates from patients with pertussis-like symptoms

Objective: To characterize two Achromobacter xylosoxidans recovered from 2 patients diagnosed with pertussis during a Bordetella pertussis surveillance program. Methods: Nasopharyngeal swabs from 2 children under 1 year of age with clinical suspicion of pertussis were analyzed by culture and PCR. Results: Two Achromobacter xylosoxidans A8, closely related to Bordetella spp. were recovered from 2 patients diagnosed of pertussis, both carrying the ptxA gene and IS418 the pertussis toxin encoding gene. Subsequently, antibiotic susceptibility was evaluated by disk-diffusion method and by PCR. Conclusions: Although more detailed studies are needed, the present data highlight the possibility that Achromobacter xylosoxidans, closely related Bordetella pertussis microorganisms and not covered under the vaccine umbrella, might also result in cases of whooping cough. Thereby further surveillance is necessary to determine the extension and relevance of their pathogenic role in order to discriminate their real public health implication.

Nephrology: is a medical specialty unattractive to Peruvian doctors?

Although the National Committee of Medical Residency (CONAREME) has increased the number of nephrology residency positions in Peru, the increase has not been proportional to the number of applicants. This is worrisome in an environment lacking of nephrologists, like our country. The Peruvian Society of Nephrology (SPN) should take the measures to make this specialty more attractive to Peruvian physicians.

Factores asociados a mala calidad de sueño en pacientes con insuficiencia renal crónica en hemodiálisis

Introducción y objetivos Los trastornos del sueño son una de las comorbilidades más comunes en pacientes en hemodiálisis. Los objetivos del estudio fueron determinar la prevalencia de mala calidad de sueño y establecer los potenciales factores asociados a ella. Materiales y métodos Estudio transversal analítico que enroló a pacientes con enfermedad renal crónica en hemodiálisis. La variable resultado fue calidad de sueño evaluada mediante la escala de Pittsburgh, mientras que las variables de exposición fueron el tiempo en hemodiálisis, la historia de diabetes mellitus tipo 2 y de hipertensión arterial, la presencia de sintomatología depresiva, la presencia de anemia y el compromiso urémico. Se usó el modelo de regresión de Poisson para verificar las asociaciones de interés, reportándose razones de prevalencia (RP) e intervalos de confianza al 95% (IC 95%). Resultados Fueron enrolados un total de 450 pacientes, de los cuales, 259 (57,5%) fueron varones, y con una edad entre 18 y 97 años. La prevalencia de mala calidad de sueño fue de 79,3% (IC 95%: 75,6-83,1%). Se encontró asociación significativa entre mala calidad de sueño y sintomatología depresiva (RP = 1,28; IC 95%: 1,17-1,39), anemia (RP = 1,18; IC 95%: 1,04-1,34) y compromiso urémico (RP = 1,26; IC 95%: 1,17-1,36) después de controlar por potenciales confusores. Conclusiones La presencia de sintomatología depresiva, anemia y el compromiso urémico estuvieron positivamente asociados a mala calidad de sueño en pacientes con enfermedad renal crónica en hemodiálisis. Un gran porcentaje de esta población sufre de mala calidad de sueño. Se sugiere desarrollar estrategias para mejorar la calidad de sueño en estos pacientes.

Prevalence of filariasis by Mansonella ozzardi and associated factors among 2 suburban communities of Iquitos, 2009

Introduction Three cases of M. ozzardi infection from 2 suburban communities in Iquitos, Peru, led to a suspicion of local transmission. The objective of the study was to determine the prevalence of filariasis by M. ozzardi and its associated factors among these communities. Materials and methods A cross-sectional study was performed, as well as an epidemiological survey and a thick smear blood test. Larvae and mosquitoes were collected. The adjusted OR (aOR) using multiple logistic regression was calculated. Results A total of 433 participants were enrolled; 58% were women. The prevalence of M. ozzardi was 1.4% and the associated factors included being a fisherman (aOR: 8.7; 95%CI: 1.1–76.0) and being on the Alto Nanay river (aOR: 11.2; 95%CI: 1.2–112.5). No significant evidence of simulidos or culicoides was found. Conclusion The low prevalence of M. ozzardi found suggests a foreign infection, probably derived from the Alto Nanay river.

Contenido de sodio en la dieta diaria de niños de un albergue peruano

Sr. Editor:
En el 2008 se registró que la hipertensión es la causa del 45% de muertes por cardiopatías y del 51% de muertes por accidentes cardiovasculares en el mundo. Muchos factores pueden contribuir al aumento de las tasas de hipertensión, pero actualmente, el debate se ha centrado en el consumo de sal.2 La Organización Mundial de la Salud (OMS) ha recomendado la reducción del consumo de sal tanto en adultos a menos de 2 g de sodio por día, como en niños de 2 a 15 años, ajustándose de acuerdo a las necesidades de energía de los niños en comparación con las de los adultos.3

La investigación científica es deficiente entre residentes de nefrología: el caso peruano

Introducción: La labor asistencial puede condicionar pobre dedicación a actividades de investigación científica en médicos que realizan la especialización de nefrología. Objetivo: Describir las prácticas de investigación científica entre los médicos residentes en nefrología y especialistas recién egresados en Perú. Material y métodos: Se realizó un estudio descriptivo de corte transversal sobre la totalidad de médicos residentes de nefrología de los dos últimos años y especialistas egresados de los dos últimos años a nivel nacional, mediante un cuestionario autoaplicado. Resultados: Se obtuvieron 40 respuestas, de las cuales el 50% correspondían a residentes. El 67.5% de los encuestados nunca realizó investigación durante la residencia. Ningún encuestado que haya realizado algún trabajo de investigación lo publicó. Casi todos consideraron a su sede hospitalaria como deficiente en investigación. Conclusión: La investigación científica entre residentes de nefrología en Perú es deficiente. Se requieren estrategias que la promuevan a este nivel.

Acute Endovascular Reperfusion Therapy in Ischemic Stroke: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Background Randomized controlled trials (RCTs) of endovascular therapy for acute ischemic stroke have had inconsistent results. We evaluated the efficacy and safety of endovascular therapy in published RCTs. Methods We performed a systematic review of RCTs of endovascular therapy with thrombolytic or mechanical reperfusion compared with interventions without endovascular therapy. Primary outcome was the frequency of good functional outcome (modified Rankin scale (mRS) of 0-2 at 90 days) and secondary outcomes were mortality at 90 days and symptomatic intracranial hemorrhage (sICH). Random-effects meta-analysis was performed and the Cochrane risk of bias assessment was used to evaluate quality of evidence. Results Ten studies involving 1,612 subjects were included. Endovascular therapy was not significantly associated with good functional outcome (Relative Risk [RR] =1.17; 95% CI, 0.97 to 1.42; p=0.10 and Absolute Risk Difference [ARD] =7%; 95%CI -0.1% to 14%; p=0.05); heterogeneity was moderate among studies (I2=30%). Mortality was unchanged with endovascular therapy (RR=0.92; 95 % CI, 0.75 to 1.13; p=0.45) and there was no difference in sICH (RR=1.20; 95 % CI, 0.79 to 1.82; p=0.39). The quality of evidence was low for all outcomes and the recommendation is weak for the use of endovascular therapy as per GRADE methodology. Conclusions Intra-arterial therapy did not show significant increase in good outcomes and no changes in either mortality or sICH in patients with acute ischemic stroke. We need further RCTs with better design and quality to evaluate the true efficacy of endovascular therapy.

Association of decreased serum brain-derived neurotrophic factor (BDNF) concentrations in early pregnancy with antepartum depression

Background: Antepartum depression is one of the leading causes of maternal morbidity and mortality in the prenatal period. There is accumulating evidence for the role of brain-derived neurotrophic factor (BDNF) in the pathophysiology of depression. The present study examines the extent to which maternal early pregnancy serum BDNF levels are associated with antepartum depression. Method: A total of 968 women were recruited and interviewed in early pregnancy. Antepartum depression prevalence and symptom severity were assessed using the Patient Health Questionnaire-9 (PHQ-9) scale. Maternal serum BDNF levels were measured using a competitive enzyme-linked immunosorbent assay (ELISA). Logistic regression procedures were performed to estimate odds ratios (OR) and 95% confidence intervals (95% CI) adjusted for confounders. Results: Maternal early pregnancy serum BDNF levels were significantly lower in women with antepartum depression compared to women without depression (mean ± standard deviation [SD]: 20.78 ± 5.97 vs. 21.85 ± 6.42 ng/ml, p = 0.024). Lower BDNF levels were associated with increased odds of maternal antepartum depression. After adjusting for confounding, women whose serum BDNF levels were in the lowest three quartiles (<17.32 ng/ml) had 1.61-fold increased odds (OR = 1.61, 95% CI: 1.13, 2.30) of antepartum depression as compared with women whose BDNF levels were in the highest quartile (>25.31 ng/ml). There was no evidence of an association of BDNF levels with depression symptom severity. Conclusions: Lower maternal serum BDNF levels in early pregnancy are associated with antepartum depression. These findings may point toward new therapeutic opportunities and BDNF should be assessed as a potential biomarker for risk prediction and monitoring response to treatment for antepartum depression.

Diagnostic Validity of the Generalized Anxiety Disorder - 7 (GAD-7) among Pregnant Women

OBJECTIVE: Generalized anxiety disorder (GAD) during pregnancy is associated with several adverse maternal and perinatal outcomes. A reliable and valid screening tool for GAD should lead to earlier detection and treatment. Among pregnant Peruvian women, a brief screening tool, the GAD-7, has not been validated. This study aims to evaluate the reliability and validity of the GAD-7. METHODS: Of 2,978 women who attended their first perinatal care visit and had the GAD-7 screening, 946 had a Composite International Diagnostic Interview (CIDI). The Cronbach's alpha was calculated to examine the reliability. We assessed the criterion validity by calculating operating characteristics. The construct validity was evaluated using factor analysis and association with health status on the CIDI. The cross-cultural validity was explored using the Rasch Rating Scale Model (RSM). RESULTS: The reliability of the GAD-7 was good (Cronbach's alpha = 0.89). A cutoff score of 7 or higher, maximizing the Youden Index, yielded a sensitivity of 73.3% and a specificity of 67.3%. One-factor structure of the GAD-7 was confirmed by exploratory and confirmatory factor analysis. Concurrent validity was supported by the evidence that higher GAD-7 scores were associated with poor self-rated physical and mental health. The Rasch RSM further confirmed the cross-cultural validity of the GAD-7. CONCLUSION: The results suggest that the Spanish-language version of the GAD-7 may be used as a screening tool for pregnant Peruvian women. The GAD-7 has good reliability, factorial validity, and concurrent validity. The optimal cutoff score obtained by maximizing the Youden Index should be considered cautiously; women who screened positive may require further investigation to confirm GAD diagnosis.

Neuroendocrine tumor in the uterine cervix: Case report

Neuroendocrine tumors of the cervix are extremely rare. Women diagnosed with small cell neuroendocrine carcinoma of the cervix have a higher frequency of metastases in the lymph nodes, lymphovascular invasion, recurrence and worse prognosis compared to those with other types of cervical neoplasia. We report the case of a 58-year-old female, with a history of six years of postmenopausal irregular vaginal bleeding, in addition to symptoms related to chronic anemia. Gynecological examination showed a tumor of 4 cm that occupied the upper third of the vagina and protruded through the cervix initially diagnosed as an abortifacient myoma, and sent to histopathology study. 90% of the tumor was small cell neuroendocrine carcinoma grade III, and the remaining 10% was squamous cell carcinoma. The patient underwent into a radical hysterectomy plus bilateral salpingo-oophorectomy, and bilateral pelvic and para-aortic lymphadenectomy. Histopathologic examination of the surgical specimen found endometrium and myometrium compromised by malignancy. Parametrium, annexes and lymph nodes were free of neoplasia. At microscopy, the result was a grade III neuroendocrine carcinoma (small cell carcinoma, infiltrating), with extensive lymphovascular emboli. The immune-histochemical study showed synaptophysin positive in areas with neuroendocrine differentiation.

Factors associated with negative appendectomy at a private hospital in Lima-Peru

Objective: Identify the frequency of negative appendectomy (NA) and associated factors associated in a private hospital in Lima. Methods: Retrospective study of all appendectomies performed between 2012 and 2013 at a private hospital of Lima-Peru. We reviewed the medical records of patients who underwent appendectomy and had a medical report of emergency. We excluded the ones without pathology reports. Adjusted ORs were calculated with a logistic regression model to identify factors associated with AN. Results: Three hundred seventy-six appendectomies were performed for suspected appendicitis 55.9% in women). The average patient age was 33.4 ± 17.6 years. We identified 28 AN cases of 363 patients (7.7%). We found that pain in right flank (aOR: 5.4; 95%CI: 1.4-20.8), negative Mc Burney (aOR: 3.6; 95%CI: 1.3- 10.5), pain in hypogastrium (aOR: 3.1; 95%CI: 1.1-8.4) and no leucocitosis (aOR: 2.9; 95%CI: 1.2-6.7) were associated factors to AN. Gynecologic conditions (53.6%) and complicated diverticular disease (14.3%) are the most common diagnosis in AN cases. Conclusion: The obtained results indicate that the presence of pain in the right flank, negative Mc Burney, pain in hypogastrium and no leukocytosis are factors that can be taken into account to prevent negative appendectomy.

Cardiovascular disease in human immunodeficiency virus-infection as a cause of hospitalization: a case-series in a General Hospital in Peru

Background Cardiovascular disease in the context of human immunodeficiency virus infection has become a major clinical concern in recent years. In the current report we assess hospitalizations due to cardiovascular disease in human immunodeficiency virus patients in a Social Security reference hospital in Peru. Methods A retrospective study was carried out between January 1996 and December 2012 in a General Hospital in Lima, Peru. Results We included 26 patients hospitalized due to cardiovascular disease. Mean age was 46.3 years (SD 12.5), predominantly male (57.7%). Ten patients (38.4%) were in Acquired Immunodeficiency Syndrome stages. Seventeen (65.4%) received high-active-antiretroviral therapy. Eleven (42.3%) had cardiac involvement and 15 (57.7%) had non-cardiac vascular involvement. The most frequent causes of cardiac involvement were pericardial effusion and myocardial infarction. On the other hand, deep vein thrombosis and stroke were the most frequent for non-cardiac vascular involvement. Conclusions Cardiovascular disease is an important cause of hospitalization in Peruvian human immunodeficiency virus patients, with differences between immunosuppression stages. Further studies analyzing associated factors are warranted.

A Shocking Cystory

A39-year-old woman from the south highland of Peru presented with abdominal distention, 10-kg weight gain, and intense stabbing pain in right upper quadrant of the abdomen. On physical examination, she had abdominal dullness and distention. She had a history of a liver cyst diagnosed by ultrasound 14 years ago. Three years ago a second ultrasound showed 3 cysts inside the first one. She did not receive any treatment before this hospitalization. The patient used to raise dogs and livestock (sheep and cattle) in her rural house when she was a child. The current ultrasound showed large cysts in liver and spleen that were confirmed by an abdominal computed tomography (CT) scan that revealed that both cysts contained hundreds of smaller cysts inside. Laboratory results showed a positive enzyme-linked immunosorbent assay (immunoglobulin G) for hydatid cyst. Laparotomy was performed, and the liver cyst was removed as well as the entire spleen.

¿Schwannoma gástrico de crecimientorápido o tumor del estromagastrointestinal?: presentación de casoclínico y revisión de la literatura

Sr. Director:
Los schwannomas, también conocidos como neurinomas, neurilemomas o fibroblastomas perineurales, se originan a partir de las células de Schwann del tejido nervioso periférico1,2. Pertenecen a la familia de tumores mesenquimatosos, son solitarios, de crecimiento lento, típicamente encapsulados y habitualmente bien diferenciados2,3. Pueden originarse del plexo de Auerbach (en la capa muscular) o del plexo de Meissner (en la submucosa), siendo el último el de menor frecuencia2. Su tamano˜ es variable (0,5-11 cm de diámetro). La localización más frecuente corresponde a las regiones cefálica y cervical1---3; raramente se originan en el tracto gastrointestinal, pero de presentarse ahí, el segmento más afectado es el estómago2.

¿Existe la equidad injusta? por la eliminación del requisito obligatorio del SERUMS

Sr. Editor.
Hemos leído la respuesta de Mujica et al. a nuestro manuscrito sobre el requisito obligatorio del servicio social en salud (SERUMS) (1). Ellos basan su comentario sobre uno de los aspectos introductorios del artículo (la búsqueda de evidencias sobre el efecto de la intervención) y no sobre el fondo de nuestra propuesta, ya que mencionan que la “inefectividad de un programa social no lo hace necesariamente inconstitucional (i.e., falacia non sequitur)”. Este comentario nos llama la atención porque en ninguna parte del manuscrito hemos afirmado que la inconstitucionalidad se deba a la falta de evidencias de efectividad del programa, sino al requisito obligatorio del SERUMS para que los recursos humanos en salud (RHUS) puedan ingresar a programas de segunda especialización, ocupar cargos en entidades púbicas, recibir becas u otra ayuda equivalente para estudios o perfeccionamiento (2). Nosotros basamos nuestro análisis de inconstitucionalidad en que este requisito obligatorio afecta tanto el derecho al trabajo y el derecho a la educación, y que por ser aplicado solo para los RHUS, es discriminatorio.

Coinfection of dengue and leptospirosis in a girl from the Peruvian Amazon

We report the case of a 10 year old girl, born and raised in the city of Iquitos in Peru who presented with headache, fever, chills, musculoskeletal pain, mild epigastric pain, epistaxis and hematemesis. On physical examination, the patient was afebrile and in good general condition. Serological tests confirmed infection of dengue and leptospirosis. The patient received intravenous hydration with sodium chloride 0.9% and penicillin G sodium, achieving a favorable clinical course such that she was discharged a few days after admission to the hospital. Although these diseases are common in the Peruvian Amazon, the simultaneous presence of both in the pediatric population is little documented; therefore, a good clinical history and laboratory tests are important for diagnosis and treatment.

Medición y magnitud del bullying en Perú

Sr. Editor. El bullying es un problema de salud pública que incluye a tres actores: la víctima, el victimario/ agresor y el observador, y es un hecho que está cada vez más presente en nuestra sociedad, pues se discute sus implicancias en escenarios de salud, educación y hasta en la prensa. Sin embargo, la información científica disponible sobre la magnitud del bullying en el Perú (Tabla 1) muestra prevalencias bastante elevadas y hasta alarmantes, por lo que es válido preguntarse si es que el bullying en el Perú se está midiendo de manera correcta.

El UCLA-PCI fue el primer instrumento desarrollado para este fin, fue hecho en Estados Unidos y luego adaptado y validado al espanol ˜ en varios estudios latinamericanos2. El EPIC es una versión extendida del UCLA y, a diferencia de este, también puede ser utilizado en pacientes con estadios clínicos avanzados. Ambos son enfermedad-específicos y, por lo tanto, más sensibles que los generales3.

Physical performance of older adults living in rural areas at sea level and at high altitude in Peru

Introduction: Living at high altitudes requires the inhabitants to adapt biologically and socially to the environment. The objective of this study was to determine the difference in physical performance (PP) in rural populations at sea level and at high altitude. Material and methods: A cross-sectional study was conducted in rural communities in Ancash, Peru, located at 3.345 meters above sea level (m.a.s.l.) and also in communities located in coastal areas at 6 m.a.s.l. PP was measured by the Short Physical Performance Battery (SPPB) and other associated factors. Adjusted prevalence ratios (aPR) were calculated. Results: A total of 130 older adults were assessed in the high altitude communities and 129 on the coast. The median age was 71.4 years, and 55.6 % were female. Low physical performance (SPPB ≤ 6) was 10.0 % at high altitude and 19.4 % on the coast (p <0.05). Factors associated with low physical performance were residing at the coast (aPR: 2.10, 95 % CI 1.02 to 4.33), self-reported poor health (aPR: 2.48, 95 % CI 1.21 -5.08), hypertension (aPR: 1.73, 95 % CI 1.01 to 2.98), and age (aPR: 1.04, 95 % CI 1.01 to 1.07), while being a farmer (aPR: 0.49, 95 % CI 0.25 to 0.97), and being independent (aPR: 0.37, 95 % CI 0,20-, 072) were found to be protective factors. It was also found that the inhabitants of the coast have a mean of 0.86 points lower total SPPB than the high altitude ones (p =0.004). Conclusions: There is an association between altitude of residence and PP in older adults. The prevalence of a low PP in older adults in rural areas at sea level is twice as high compared to those living in high altitude rural communities
