Osteoarthritis Increases the Frequency and Duration of Postoperative Hand Clinic Visits after Carpal Tunnel Release.

Background: Carpal tunnel syndrome affects up to 6% of the general population, and surgical intervention is often required to ameliorate symptoms. Osteoarthritis (OA) is a common condition that often coexists with carpal tunnel syndrome. We hypothesized that patients with preexisting OA use more healthcare resources after carpal tunnel release (CTR) than patients without arthritis. Methods: This was a retrospective cohort study at a single academic center between January 1, 2018 and November 1, 2021. Patients who underwent CTR were included. Preoperative carpal tunnel symptoms, diagnostic tests, medications, and concomitant OA were abstracted. Hand, wrist, and basal joint arthritis were specified. The primary outcome was healthcare utilization represented by duration and frequency of hand clinic and occupational therapy (OT) follow-up. In total, 312 hands were included. Multivariable analysis was performed. Results: The average duration of hand clinic follow-up among patients without arthritis was 25.3 days compared with 87.1 days for patients with any arthritis (P = 0.0375) and 172 days for patients with wrist arthritis (P = 0.012). The average number of postoperative surgeon visits was increased in patients with hand arthritis, with an average of 2.3 visits versus 1.34 visits for patients without arthritis (P = 0.003). Both the number of OT visits and the duration of OT follow-up did not differ between cohorts. Conclusion: After CTR, patients with preexisting OA use more healthcare resources than patients without OA.

Cesarean rate in selected hospital network of private sector: A retrospective study.

INTRODUCTION: In Spain over the last two decades, cesarean section (CS) rates have increased from 15 to 25% in the Public Health Sector and from 28 to 38% in the private sector. There are multiples causes for this rise, which are often unclear. The aim of our study is to collect and analyze all the CS rates data from a hospital network of the 42 Quirónsalud Hospitals (private sector) and to assess its distribution regarding the different types of hospitals and patient characteristics. MATERIAL AND METHODS: An observational retrospective study between 2017 and 2018 was performed. Hospitals are classified into three groups: large hospitals (11), medium hospitals (17) and small hospitals (14). The cesarean section rate was measured by patient categorization into three groups: total deliveries, low risk cesarean sections and low risk cesarean sections without previous cesarean delivery. RESULTS: We analyzed 62,685 deliveries: 42,987 were vaginal deliveries (68.6%) and 19,698 CS (31.4%). The mean age for the total number of deliveries was 34.18 years old, whilst the mean age for the low-risk group was 34.12. Of the 19,698 CS, 18.36% (3618) were in high-risk population and 81.63% (16,080) in low risk population. 69.54% (11,183) of the low-risk CS were in patients without a previous CS. CONCLUSIONS: The overall rate of CS in the Quirónsalud group is slightly higher than the one from the Public Healthcare. The older maternal age as well as the hospital resources involved in the delivery attendance can explain this difference.

First-trimester fasting glycemia as a predictor of gestational diabetes (GDM) and adverse pregnancy outcomes.

AIMS: Studies to prevent gestational diabetes (GDM) have shown the best results when lifestyle measures have been applied early in pregnancy. We aimed to investigate whether first-trimester fasting plasma glucose (FPG) could predict GDM risk and adverse pregnancy outcomes. METHODS: A retrospective analysis of prospectively collected data from singleton pregnancies who were attended at our hospital between 2008 and 2018 (n = 27,198) was performed. We included patients with a recorded first-trimester FPG and complete pregnancy data (n = 6845). Patients under 18, with pregestational diabetes or reproductive techniques, were excluded. First-trimester FPG was evaluated as a continuous variable and divided into quartiles. GDM was diagnosed by NDDG criteria. The relationship between first- and second-trimester glucose > 92 mg/dL was also investigated. The relationship between FPG and pregnancy outcomes was assessed in 6150 patients who did not have GDM. RESULTS: Maternal age was 34.2 ± 3.9 years, BMI 23.1 ± 3.7 kg/m2 and mean FPG 83.0 ± 7.3 mg/dL. Glucose quartiles were: ≤ 78, 79-83, 84-87 and ≥ 88 mg/dL. First-trimester FPG predicted the risk of GDM (7%, 8%, 10.2% and 16% in each quartile, p < 0.001) and the risk of second-trimester glucose > 92 mg/dL (2.6%, 3.8%, 6.3% and 11.4% in each quartile, p < 0.001). FPG was significantly associated with LGA (8.2%, 9.3%, 10% and 11.7% in each quartile, p = 0.011) but not with other obstetrical outcomes. In a multivariate analysis including age, BMI, tobacco use, number of pregnancies and weight gained during pregnancy, first-trimester FPG was an independent predictor of LGA. CONCLUSIONS: First-trimester FPG is an early marker of GDM and LGA.

Delayed-onset paraparesis in Lassa fever: A case report.

Lassa fever (LF) is an endemic viral hemorrhagic fever in West Africa. Among the serious complications of the disease are neurological manifestations whose spectrum is incompletely known. Here we report the case of a 61-year-old man who developed a delayed-onset paraparesis a few weeks after getting infected with Lassa virus, thereby suggesting a possible association between LF and spinal cord disorders.

Maternal fasting glycemia and adverse pregnancy outcomes in a Mediterranean population.

AIMS: The hyperglycemia and adverse pregnancy outcome study demonstrated a continuous association between fasting plasma glucose (FPG) levels below those diagnostic of diabetes and adverse neonatal outcomes. We aimed to investigate whether the same association was found in a Mediterranean population. METHODS: A retrospective analysis of singleton pregnancies attended at our Hospital between 2008 and 2015 (n = 5203). FPG was evaluated in the second trimester, and it was divided into 7 categories (1 < 75, 2 75-79, 3 80-84, 4 85-89, 5 90-94, 6 95-99 and 7 100-124 mg/dL). Pregnancy outcomes included elective cesarean delivery, gestational hypertensive disorders (GHD), large for gestational age (LGA), small for gestational age (SGA), macrosomia, prematurity, severe prematurity and APGAR at 1 min <7. RESULTS: Maternal age was 33.8 ± 3.8 years, and BMI at first antenatal visit was 22.9 ± 3.5 kg/m2; mean FPG was 79 ± 7 mg/dL. A positive association was observed between FPG and LGA (p < 0.001), GHD (p = 0.004) and prematurity both <37 and <34 weeks of gestation (p = 0.001 and p = 0.004). FPG and SGA were inversely related (p = 0,038). FPG was not significantly related to rate of C-section or APGAR. Adjusted odds ratios associated with 1 standard deviation increase in the fasting plasma glucose (7 mg/dL) were 1.26 (1.15 to 1.37) for LGA, 1.28 (1.09 to 1.49) for GHD and 0.83 (0.74-0.93) for SGA. In a multivariate analysis controlling for confounders, FPG remained associated with LGA. CONCLUSIONS: We found an association between FPG levels, below those diagnostic of gestational diabetes according to our guidelines, and adverse maternal and neonatal outcomes in a Mediterranean population.

The TITAN-AMI multicenter registry evaluating the usage of Titan2 stent in patients with ST segment elevation myocardial infarction. Final result at 12-month follow-up.

AIM: Primary percutaneous coronary intervention with stent implantation is the recommended treatment for patients with ST elevation myocardial infarction (STEMI). Data from randomised trials showed good performance by a titanium-nitric-oxide coated stent in this context. The aim of this study was to confirm these data. METHODS: A multicentre registry was compiled in 23 hospitals in Spain in an all-comers population. We selected patients with STEMI from a global Titan AMI registry that included patients with acute coronary syndrome. Primary endpoint was the composite of cardiac death, non-fatal myocardial infarction, stent thrombosis and target lesion revascularisation, at 12-month follow-up. RESULTS: The study included 893 patients with STEMI. We included all possibilities for PCI: 86.6% primary, 5% facilitated after successful fibrinolysis and 8.4% rescue PCI after failed fibrinolysis. The primary endpoint was reached in 8.4% of the patients: cardiac death 2.7%, reinfarction 3.4%, target lesion revascularisation 3.5% and definite or probable stent thrombosis 2.8%. The majority of stent thromboses presented in the first 30 days after PCI. CONCLUSION: A bioactive stent (titanium-nitric-oxide coated stent) is a possible alternative for the treatment of patients with STEMI. One-year follow-up showed better results than those presented by a regular bare-metal stent or first-generation drug-eluting stent in terms of stent thrombosis.

Analysis of quality of nuchal translucency measurements: its role in prenatal diagnosis.

OBJECTIVE: Quantitative analysis of the quality of nuchal translucency (NT) measurements. METHODS: First-trimester combined screening for Down syndrome was performed to all pregnant women attended in our Department from October 2003 to November 2009. NT was measured according to the Fetal Medicine Foundation (FMF) criteria by 20 trained obstetricians. The performance of NT measurements was retrospectively analyzed with regard to several quality control standards. Accuracy according to experience, professional profile, crown rump length (CRL) values, and FMF certification was statistically tested. RESULTS: A total of 14978 NT measurements were assessed. (1) The mean operator-specific median NT-MoM values was 0,98. (2) Mean percentage of cases >95th and <5th centiles were 5,0% and 4,2%, respectively. (3) Logarithmic mean and SD of the NT MoM values were 0,00 and 0,13, respectively. (4) The DR for trisomy 21 at screening time was 90,7% for a FPR of 6,7% for standard screening strategy. (5) According to Cumulative SUM (CUSUM) figures, the performance was more acceptable in FMF-certified operators. CONCLUSION: Overall, quality standards show optimal NT measurements in our unit. Operator experience, a dedicated profile to fetal medicine, CRL over 60 mm, and FMF certification have a significant positive impact on the quality standards.

Evaluación de los sistemas de medición de la fuerza muscular en el ámbito de la práctica musical. Aproximación a un prototipo apto para la práctica instrumental / Evaluation of the systems for measuring muscle strength applied to musical practice. Approach to a prototype suitable for instrumental practice

Objetivo: Evaluar los sistemas de medida de la fuerza, en tiempo real, que ejerce la mano sobre el instrumento al tocar (piano y guitarra) y conocer la fuerza ejercida por la mano del músico, en tiempo real, sobre el instrumento. Material y Método: Se analizaron sobre el instrumento, en un guitarrista y un pianista experimentados. En cada sistema analizado se valoró: el grado de interferencia con el gesto técnico musical; la posibilidad de intercambiarlo de un instrumento a otro; la resistencia al deterioro con el uso (especialmente al trabajar sobre cuerdas); la existencia de un sistema y software de captura y análisis de los datos que permitiera al usuario definir alarmas o niveles de alerta útiles para poder hacer un trabajo de reeducación de la tensión utilizada para tocar (biofeedback). Se estableció un protocolo de pruebas y se experimentó sobre ambos instrumentos. Con el método que dio mejor resultado se procedió al estudio de la fuerza ejercida por la mano del músico sobre el instrumento. Resultados: Las medidas recogidas mostraron en el caso de la guitarra un pico de fuerza máximo de 9,14N (0,93Kg) y en el piano se superaban habitualmente los 9,8N (1kg de fuerza). Conclusiones: Los sensores de presión miniaturizados recubiertos con una funda de látex ultrafino han resultado ser eficaces para el estudio de la fuerza isométrica y concéntrica desarrollada por la mano del músico (AU)

Objetive: determine, in real time, its usefulness in the study of the force exerted by the hand of the musician on the instrument (piano and guitar) and the force exerted by the hand of the musician on the instrument, in real time. Material and methods: systems better adapted to the requirements of musical practice were chosen and analyzed on the instrument, using as experimental subjects a guitarist and a pianist. For every system examined the following was considered: the degree of interference with the musical technical act; easiness to swap the system from one instrument to another; resistance to deterioration with use (especially working on strings) and existence of a system and software to capture and analyze data that allow the user to set alarms or alert levels that will help him to do reeducation of the tension used to play (biofeedback) were analysed. Results: The guitar measures showed a maximum peak force of 9.14 N (0.93Kg) and the piano usually exceeded 9.8 N (1kg force). The other analized systems (thermal imaging, Chronopic, EMG and accelerometer) let us study the force, however important limiting factors behaved they were discarded. Conclusions: Miniature pressure sensors coated with an ultrathin latex sheath have proved effective for the study of the isometric and concentric force developed by the hand of the musician (AU)

Determinación de la utilidad de la espectroscopia por luz casi-infrarroja (NIRS) en el estudio de la mialgia de esfuerzo en los antebrazos de los músicos / Determination of the utility of Near-Infrared Spectroscopy (NIRS) in the study of exertional mialgia in musician’s forearms

Objetivo: Determinar si la mialgia de esfuerzo en los antebrazos de los músicos está asociada a un trastorno de irrigación u oxigenación muscular condicionado por una alteración en la presión intracompartimental (PIC). Material y método: Se estudiaron 29 músicos con mialgia de esfuerzo en antebrazos y un grupo control de 9 músicos sanos. Se midió simultáneamente la presión en el compartimento extensor superficial del antebrazo y la oxigenación tisular mediante espectroscopia con luz casi-infrarroja. Las mediciones se realizaron antes, durante y después de realizar un trabajo dinámico de flexo-extensión contra resistencia de los dedos hasta la fatiga. Resultados: El valor medio de la PIC en reposo fue de 13,22 mmHg (grupo control) y de 12,42 mmHg (grupo mialgia). La PIC post-esfuerzo fue de 17,19 mmHg y de 14,83 mmHg. Los valores de la PIC no mostraron diferencias estadísticamente significativas entre los dos grupos. Se objetivaron diferencias significativas de oxihemoglobina entre los dos grupos en la fase de recuperación. Conclusiones: La mialgia de esfuerzo podría asociarse a una alteración en la oxigenación e irrigación tisular pero sin existir indicios de estar provocado por un aumento patológico de la PIC (AU)

Aim: investigate whether exertional myalgia in musician’s forearms is a disorder associated with a deficiency on muscle irrigation/oxygenation and whether this is determined by an increased intracompartmental pressure (ICP). Material and methods: We have studied 29 musicians with forearm’s exertional myalgia and a control group of 9 healthy players. In all them the ICP, measured in the forearm superficial extensor compartment, and the tissue oxygenation, by means of near-infrared spectroscopy, was simultaneously recorded. Measurements were taken before, during and after doing dynamic fingers flexion-extension work against resistance to fatigue. Results: The mean resting ICP was 13.22 mmHg (control group) and 12.42 mmHg (myalgia group). Postexertion ICP was 17.19 mmHg and 14.83 mmHg. The PIC values showed no statistically significant differences between the two groups. Significant discernible differences were seen in the amount of oxyhemoglobin between he two groups in the recovery phase. Conclusions: Exertional myalgia seems to be associated with an alteration in tissue oxygenation and irrigation but there are no indicators of being caused by a pathological increase in ICP (AU)

Translocación 3; 22 (p13; q12) de novo con repercusión fenotípica. A propósito de un caso / Translocation 3; 22(p13; q12) de novo with pathological phenotype. Report of a case

Se comunica el caso de un neonato nacido de embarazo gemelar con diagnóstico prenatal de traslocación (3,22) de novo, realizado por la detección de una cardiopatía a las veinte semanas de gestación. Los padres y feto gemelo tienen cariotipo normal y la paciente presenta fenotipo clínico patológico, con bajo peso, rasgos dismórficos, fisura palatina y comunicación interventricular, lo que sugiere una “Translocación desequilibrada” (AU)

We report a case of a newborn product of a twin pregnancy with prenatal diagnosis of translocation (3,22) “ de novo”. It was made by detection a cardiopathy in twenty week. Parents and twin fetus have normal karyotype. Our patient presents a clinical pathological phenotype with underweight, dysorphic features, cleft palate and interventricular communication. This suggests an “unbalanced translocation” (AU)

A rapid method for detection of catalase-positive and catalase-negative bacteria based on monitoring of hydrogen peroxide evolution at a composite peroxidase biosensor.

The rapid detection of catalase-positive and catalase-negative bacteria in complex culture media has been accomplished by monitoring of hydrogen peroxide consumption or generation with a graphite-Teflon-peroxidase-ferrocene composite electrode. Escherichia coli and Streptococcus pneumoniae have been used as model catalase-positive and catalase-negative bacteria, respectively. Hydrogen peroxide evolution was amperometrically measured at 0.00 V. Experimental conditions, including the working solution composition, the incubation time and the hydrogen peroxide concentration, were optimized. The reusability of the biosensor was improved by placing a nylon membrane on the bioelectrode surface to prevent fouling caused by the bacterial medium. The developed methodology allowed the detection of E. coli and S. pneumoniae at concentration levels of approximately 2x10(6) and 2x10(5) cfu/mL, in assays taking 10 and 15 min, respectively, without any pre-concentration step or pre-enrichment procedure.

Lectin-modified piezoelectric biosensors for bacteria recognition and quantification.

The use of lectins for microorganism biosensors fabrication is proposed. Lectins are immobilised onto a gold-plated quartz crystal for direct piezoelectric label-free transduction of the bacteria-lectin binding event using an electrochemical quartz crystal microbalance (EQCM). Concanavalin A (Con A) and Escherichia coli were used for the evaluation of the lectin immobilisation method and the biosensor performance. Adsorption on nonpolarised and polarised (-0.200 V) gold-coated quartz crystals and immobilisation through avidin-biotin binding were checked for Con A surface attachment. Lectin-bacteria binding was evaluated in all cases. With a crystal modified with Con A via avidin-biotin immobilisation we obtained a linear calibration plot between 5.0 x 10(6) and 2.0 x 10(7) cfu mL(-1) by measuring frequency changes with E. coli concentration 1 h after bacteria addition. A remarkable increase in sensitivity was achieved when the analytical solution contained free biotinylated Con A, as a consequence of multiple lectin adhesion to Escherichia coli cell wall, which produced an accumulation of Con A-E. coli conjugates in the form of multilayers at the electrode surface. A detection limit of approximately 1.0 x 10(4) cfu mL(-1) was achieved. Moreover nonspecific adsorptions were minimised. Using Con A and lectin from Arachis hypogaea, different response profiles were achieved for Escherichia coli, Staphylococcus aureus and Mycobacterium phlei, thus demonstrating the feasibility of bacteria discrimination. An approach involving filtering of free and lectin-bound bacteria and introduction of a filter in the measuring cell allowed a significant frequency change to be obtained for an E. coli concentration of 1.0 x 10(3) cfu mL(-1) in order to further increase the sensitivity and discriminate between viable and nonviable cells; an approach using electrochemical measurements of bacterial catalase activity was also checked.

Resultados del estudio del genotipado RhD fetal en plasma materno / Results of the study of the fetal RHD genotyping in maternal plasma

Introducción. Se evalúa la eficacia en la determinacióndel RhD fetal a partir de sangre materna.Material y métodos. Estudio prospectivo y descriptivo.Se obtuvieron 90 muestras sanguíneas de gestantes RhD negativo con pareja RhD positiva que controlaron su gestación en nuestro centro entre septiembre de 2004 y enero de 2006, previa autorización y consentimiento expreso de las pacientes. Las muestras de sangre materna se enviaron al laboratorio de biología molecular para cuantificar los exones 7 y 10 del gen RHD. Posterior-mente se compararon los resultados obtenidos del genotipado RHD fetal con el fenotipo de RhDde los recién nacidos.Resultados. El genotipado informó de 69 fetos RhD positivo (76,6%) y 21 RhD negativo (23,3%). Se obtuvieron seis falsos positivos y tres falsos negativos. La sensibilidad de la prueba fue del 95,45% y la especificidad del 75%.Discusión. Se detecta una elevada tasa de falsos negativos, que podría explicarse por diferentes razones relacionadas con la obtención y la manipulación de la muestra (semana de gestación, técnica de extracción y técnica de amplificación).Conclusiones. La elevada tasa de falsos negativos en ladeterminación del RhD fetal a partir de sangre materna, que corresponde a casos susceptibles de aloinmunización materna y por tanto de desarrollar enfermedad hemolítica del feto recién nacido, obliga a una correcta reevaluación de la técnica empleada y de la interpre-tación de los resultados

Introduction. We evaluate the effectiveness in thedetermination of the foetal RhD from the mother’s blood.Material and methods. 90 Rh negative pregnant womenwith positive RhD couples allowed us, by signing aconsent form, to use their blood samples for this study. All these patients have been monitored in our centre from September 2004 to January 2006. The maternal blood samples were sent to the molecular biology laboratory for the quantification of exones 7 and 10 of the RhD’s gene. After that, the results obtained from the foetal RhD genotypes were compared with the phenotypes of the newborn’s RhD.Results. The results of the genotyping showed that69 (76,6%) of the foetuses were RhD positive, whereas 21(23,3 %) were RhD negative. The sensitivity of the testwas 95.45% and the specificity 75%. Six tests came outfalse positives and three false negatives.Discussion. Several factors related to the obtainingof the sample and the way it is manipulated (pregnancyweek, the extraction or amplification technique) couldexplain the high rate of false negatives.Conclusion. The high prevalence of false negativesdetected after a foetal RhD test on maternal blood forcesus to reconsider the used technique and to improve theway we interpret the results, taking into account thatthere is a risk of maternal isoimmunization and consequently an haemolytic disease on the newborn (AU)

[Scrotal hair in infants]. / Vello escrotal en lactantes.

The presence of pubic hair is exceptional in healthy infants of both sexes. In most of the cases described in the literature, the process was self-limited and no etiology was found. Nevertheless, in some patients, this finding has been associated with other manifestations of hyperandrogenism related to potentially serious diseases such as congenital adrenal hyperplasia or virilizing tumors. In the present article, we describe seven infants followed-up in the Pediatric Endocrine Clinic because of scrotal hair. In all patients, the process was self-limited and resolved spontaneously and no hormonal or developmental alterations were observed. Key words: Scrotal hair, infants, virilization.

Efectos del yogur enriquecido con isómeros del ácido linoleico conjugado, sobre resistencia a la insulina en adolescentes obesos / The effects of yogurt with isomer enriched conjugated linoleico acid on insulina resistance in obese adolescents

El incremento en la incidencia de obesidad es uno de los problemas sanitarios más relevantes en los países en desarrollo. La resistencia a la insulina juega un papel clave en las alteraciones metabólicas asociadas a la obesidad. Son pocas las intervenciones que permitan, de forma eficaz, reducir el peso corporal y las alteraciones metabólicas como consecuencia de la misma. Objetivos. Los objetivos del presente trabajo fueron determinar si la administración de una mezcla de isómeros de ácido linoleico conjugado (CLA) reduce el peso corporal y mejora la resistencia a la insulina en adolescentes obesos. Diseño experimental. Se llevó a cabo un estudio doble ciego, caso-control, donde se estudiaron 39 pacientes adolescentes obesos, a los cuales de forma aleatoria se les administro diariamente 200 g de yogur líquido suplementado con 3 g de CLA o placebo, durante 16 semanas. Se determinó el peso, talla índice de mas corporal (IMC), colesterol total en plasma y el HDL, insulina, glucosa, adiponectina, así como el índice de resistencia a la insulina (HOMA), antes del inicio de la ingesta, al finalizar, y tras un periodo sin la suplementación. Resultados. No se observaron diferencias significativas en el peso, talla, IMC, colesterol total y en HDL, y adiponectina, entre el grupo suplementado con CLA y el grupo placebo, ni al inicio del estudio, durante y tras el tratamiento. Tras 16 semanas de suplementación con CLA, los nivels de glucosa plasmática y el índice de resistencia a la insulina (HOMA) se redujeron comparado con el grupo placebo (p<0.05). Conclusión. En adolescentes obesos, la administración de CLA disminuye el índice de resistencia a la insulina, independientemente de los cambios en el peso y en el IMC (AU)

Increase in the incidence of obesity is one of the most relevant health care problems in the developing countries. Insulin resistance plays a key role in obesity associated metabolic disorders. There are few interventions that make it possible to effectively reduce body weight and metabolic disorders that occur as a consequence of it. Objectives: This present study aimed to determine if the administration of a mixture of conjugated linoleic acid (CLA) isomers reduces body weight and improves insulin resistance in obese adolescents. Experimental design. A double blind, case – controlled, study was conducted in which 39 obese adolescent patients were studied. Daily, they were randomly administered 200 g of liquid yogurt supplemented with 3 g of CLA, or placebo, for 16 weeds. Weight, height, body mass index (BMI), total cholesterol in plasma and in HDL, insulin, glucose, adiponectin and insulin resistance index (HOMA) were measured before the onset of intake, at completion, and after a period without supplementation. Results: No significant differences were observed in weight, height, BMI, total cholesterol and in HDL and adiponectin between the group supplemented with CLA and the placebo group at the onset of the study, during and after the treatment. After 16 weeks of supplementation with CLA, the plasma glucose levels and insulin resistance index (HOMA) were reduced compared with the placebo group (p<0.05). Conclusion. In obese adolescents, administration of CLA decreases the insulin resistance index, independently of weight changes and BMI changes (AU)

Vello escrotal en lactantes / Scrotal hair in infants

La aparición de vello sexual es excepcional en los lactantes de ambos sexos. La mayoría de los casos descritos en la bibliografía constituyen procesos autolimitados, en los que su etiología no ha sido definida. Sin embargo, en algunos casos se ha asociado con otras manifestaciones de hiperandrogenismo relacionadas con procesos potencialmente graves como son la hiperplasia suprarrenal congénita y tumores productores de andrógenos. En el presente artículo se describe los casos de 7 lactantes varones que fueron vistos en la consulta de endocrinología pediátrica por vello escrotal. En todos ellos el proceso fue autolimitado, sin que se observaran alteraciones hormonales o en el desarrollo (AU)
