Anconeus and pronation: a palpatory and ultrasonographic study.

PURPOSE: Depending on its axis, pronation varies from the radius rotation around the steady ulna to the reciprocal adduction of the radius and abduction of the ulna. While there is no question that pronator teres is a central pronation agonist, anconeus's role is not settled. The current investigation comparing palpation and ultrasonography in these two muscles during pronation along the axis capitulum-second digit evolved from a serendipitous finding in a clinical anatomy seminar. METHODS: Single-hand palpation and two-transducer ultrasonography over anconeus and pronator teres were used on ten normal subjects to investigate their contraction during pronation around the capitulum-second digit axis. These studies were done independently and blind to the results of the other. The statistical analysis between palpation and ultrasonography was performed with Cohen's kappa coefficient and the χ2 test. RESULTS: On palpation, on resisted full pronation, anconeus contracted in 8/10 subjects and pronator teres in 10/10 subjects. Without resistance, the corresponding ratios were 5/10 and 9/10. On two-transducer ultrasonography, the comparable ratios were 7/10 and 10/10, and 3/10 and 10/10. A fair concordance (Cohen's kappa = 0.21) between palpation and ultrasonography in detecting the simultaneous status of anconeus and pronator teres during resisted full pronation. Anatomic dissection illustrated the elements involved. CONCLUSIONS: Plain palpation confirmed by ultrasonography showed the simultaneous contraction of anconeus and pronator teres during resisted pronation in most of the studied subjects. The study suggests that palpation can be helpful in directly studying muscle activity during movement.

Inter-rater Accuracy and Reliability of a Palpation Protocol of the C7 Spinous Process Comprising a Combination of 3 Traditional Palpation Techniques.

OBJECTIVE: The purpose of this study was to determine the accuracy and intrarater reliability of a palpatory protocol based on a combination of 3 palpatory methods to identify both the C7 spinous process (C7 SP) and the factors that affect the errors and inaccuracy of palpation. METHODS: Twenty-five women between the ages of 18 and 60 years were submitted to a palpation protocol of the C7 SP, and a radiopaque marker was fixed on the skin at the possible location of the vertebrae. A radiograph and a photograph of the cervical spine were obtained in the same posture by a first rater. A second rater performed the same palpation protocol and took a second photograph. The accuracy and measurement error of the palpation protocol of C7 SP were assessed through radiographic images. The inter-rater reliability was estimated by the interclass correlation coefficient and assessed using photographs of each rater. The Pearson's correlation coefficients (r), the Fisher exact test, and the χ2 test were used to identify the factors associated with the error and inaccuracy of palpation. RESULTS: Accuracy of the C7 palpation was 76% with excellent reliability (interclass correlation coefficient = 0.99). There was a moderate correlation between weight and the measurement of palpation error (r = -0.6; P = .003). One hundred percent of inaccuracy palpation was related to the increased soft-tissue thickness (P = .005) in the cervical region. CONCLUSION: The palpation protocol described in this study was accurate and presented excellent reliability in identifying the C7 SP. Increased weight and dorsocervical fat pad were associated to error and palpation inaccuracy, respectively.

Prevalence and influence of clinical and subclinical mastitis in the service period of dairy cows in Tarumirim (MG) / Prevalência e influência da mastite clínica e subclínica no período de serviço de vacas leiteiras em Tarumirim (MG)

The objective was to assess the prevalence and influence of clinical and subclinical mastitis during the service period of cows in a herd in Tarumirim (MG), from October 2019 to May 2020. Around 65 Gir x Holstein and Guzerá x Holstein lactating crossbred cows were evaluated. Subclinical mastitis was diagnosed by means of the California Mastitis Test (CMT), and clinical mastitis, by means of the strip cup test and the animals' clinical signs. Pregnancy after calving was diagnosed by the rectal palpation method, with the aid of ultrasound. The time from calving to conception was considered as the service time. The prevalence rates of clinical and subclinical mastitis were 2.9 and 63.7%, respectively, throughout the experimental period. The mean service period was shorter (p<0.05) in healthy cows (63.1 days) than in cows with subclinical mastitis (88.5 days) and clinical mastitis (111.2 days). The service period increased by 30.9 days for each mammary quarter with clinical mastitis (p<0.05). With each increase in the degree and days of duration of clinical and subclinical mastitis, the service period rose by 25.4 and 6.5 days, and 8.5 and 0.6 days, respectively (p<0.05). Therefore, mastitis increases the service period of dairy cows. Good milking hygiene and animal handling practices should be adopted in order to reduce the prevalence of mastitis in the herd.(AU)

Objetivou-se avaliar a prevalência e influência da mastite clínica e subclínica no período de serviço de vacas em um rebanho de Tarumirim (MG), ao longo de outubro de 2019 a maio de 2020. Em torno de 65 vacas mestiças Gir x Holandês e Guzerá x Holandês em lactação foram avaliadas. A mastite subclínica foi diagnosticada por meio de California Mastitis Test(CMT) e a mastite clínica por meio do teste da caneca e sinais clínicos dos animais. O diagnóstico de gestação após o parto foi realizado pelo método de palpação retal, com auxílio de ultrassom. O tempo do parto até a concepção foi considerado como o tempo de serviço. As prevalências de mastite clínica e subclínica foram de 2,9 e 63,7%, respectivamente, ao longo do período experimental. O período de serviço médio foi menor (p<0,05) em vacas sadias (63,1 dias) que em vacas com mastite subclínica (88,5 dias) e clínica (111,2 dias). O período de serviço aumentou 30,9 dias a cada quarto mamário com mastite clínica (p<0,05). A cada aumento do grau e dias de duração da mastite clínica e subclínica, o período de serviço aumentou 25,4 e 6,5 dias e 8,5 e 0,6 dias, respectivamente (p<0,05). Portanto, a mastite aumenta o período de serviço de vacas leiteiras. Boas práticas de higiene de ordenha e manejo dos animais devem ser adotadas para reduzir a prevalência de mastite no rebanho.(AU)

Craniocervical Posture Assessed With Photogrammetry and the Accuracy of Palpation Methods for Locating the Seventh Cervical Spinous Process: A Cross-sectional Study.

OBJECTIVE: The purpose of this study was to compare craniocervical posture assessed by photogrammetry using 2 distinct palpation methods for locating the spinous process of the seventh cervical vertebra (C7SP). METHODS: This cross-sectional study was conducted in 2 phases. In phase I (n = 42), the assessor's accuracy in locating the C7SP using the flexion-extension and the modified thorax-rib static methods was compared to radiography. In phase II (n = 68), the craniocervical posture was analyzed with photogrammetry after palpation using the 2 methods. Neck pain intensity and disability were also determined. RESULTS: The accuracy in locating the C7SP was higher using the modified thorax-rib static method (67%, 95% confidence interval [CI], 55-79) compared to the flexion-extension method (38%, 95% CI, 26-50, P = .016). Lower values of the craniocervical angle were obtained with the flexion-extension method than the modified thorax-rib static method (mean difference = -1.1°, 95% CI, -1.6 to -0.6, P < .001). However, both palpation methods resulted in similar classifications of participants as with or without forward head posture (P = .096). Weak correlations were observed between the craniocervical angle and neck pain intensity (ρ = -0.088 and -0.099, respectively) and disability (ρ = -0.231 and -0.249, respectively). CONCLUSION: Craniocervical angles obtained using palpation methods with different accuracies were different, although the magnitude of the difference was insufficient to lead to different classifications of a forward head posture in adults with mild neck pain and disability. Craniocervical posture was weakly correlated with neck-pain intensity and disability.

Are visual inspection and digital palpation reliable methods to assess ability to perform a pelvic floor muscle contraction? An intra-rater study.

AIMS: To investigate the intrarater reliability of visual inspection and digital palpation to classify women's ability to perform a voluntary pelvic floor muscle (PFM) contraction and the association between the two methods. METHODS: This was a test-retest clinical study including 44 women. The ability to perform a PFM voluntary contraction was evaluated two times in all participants using visual inspection and digital palpation. All analyzed participants were assessed with a 7-day interval between the two assessments and by the same examiner. Kappa's agreement coefficient was used to estimate the intrarater reliability, and Fisher's exact test was used to analyze association between the two methods. RESULTS: This study found a substantial intrarater reliability of visual inspection (k = 0.73; p < .001) and digital palpation (k = 0.74; p < .001). A significant association between visual inspection and digital palpation was found at both time points (p < .001). CONCLUSION: Both visual inspection and digital palpation have substantial intrarater reliability and visual inspection can be recommended when vaginal palpation is not tolerated.

Abdominal Palpation Does Not Modify the Number of Bowel Sounds in Healthy Volunteers and Gastrointestinal Outpatients.

BACKGROUND: The effect of abdominal palpation on bowel sounds is controversial. The authors developed an auscultation apparatus to count bowel sounds and determined whether abdominal palpation modifies the number of bowel sounds in healthy volunteers and gastrointestinal outpatients. METHODS: Four medical students developed an auscultation apparatus by attaching a Littmann stethoscope to an electret condenser microphone. The students examined 20 healthy volunteers and 20 gastrointestinal outpatients between March and June 2018. Abdominal auscultation lasting 4 minutes (1-minute each quadrant) was performed before and after abdominal palpation with registration of sound tracings. The software Audacity was used to count the bowel sounds. The effect of palpation on bowel sounds was analyzed using Generalized Estimating Equations. RESULTS: The volunteers were predominantly young (mean ± SD, 21 ± 2 years) and men (70%), whereas the outpatients were older (60 ± 11 years) and women (80%). The apparatus was able to generate sound tracings with good quality from all participants. In the comparison before/after palpation, the number of bowel sounds did not differ either in volunteers (mean ± SD, 12.6 ± 4.7 and 11.6 ± 3.5; P = 0.482) or in patients (15.6 ± 7.5 and 15.8 ± 7.9; P = 0.714). In the analysis of all participants, the difference before-after palpation was not statistically significant (mean ± SD, 14.1 ± 6.3 and 13.7 ± 6.4, respectively; P = 0.550; mean difference = 0.4; 95% CI -1.2 to 2.0) and did not depend on the group studied. CONCLUSIONS: Using an apparatus devised by medical students, the authors found that abdominal palpation did not modify the number of bowel sounds in healthy volunteers and gastrointestinal outpatients.

Location and removal of non-palpable subdermal single-rod contraceptive implant.

OBJECTIVE: The objective of the study was to present the experience of the family planning service Hospital General de México, in locating and removing no palpable subdermal single-rod contraceptive implants. MATERIALS AND METHODS: A descriptive, prospective, and cross-sectional study was performed from January 2011 to April 2018. RESULTS: Hundred and sixty-four patients in whom the implant was not palpable were reviewed, the time between insertion and removal averaged 3.3 years (maximum 10 years and minimum 3 months). Three implants were inserted in the right arm, the rest on the left one. Forty-seven implants were found in fatty tissue (29%), 18 in fascia (11%), 94 in muscle (57%), 2 in the armpit (1.2%), and 3 were not found (1.8%). CONCLUSIONS: The no palpable implant is caused by an incorrect insertion technique. Migration should not be assumed as a cause of difficult location. Amount of non-palpable implants is not possible to determine due to a lack of records, but approximately 3% are considered non-palpable. Ultrasound has proven to be the study of choice to locate an incorrect inserted implant. In this case, the total number of implants was located, except in two patients.

MATERIALS Y MÉTODOS: Estudio clínico descriptivo, prospectivo y transversal, realizado desde enero de 2011 hasta abril de 2018 en el servicio de planificación familiar del Hospital General de México Dr. Eduardo Liceaga. RESULTADOS: Se incluyeron 164 pacientes con implantes no palpables, de los cuales 161 se localizaron por ultrasonido. El promedio entre la inserción y el retiro fue de 3.3 años. Tres implantes fueron insertados en el brazo derecho y el resto en el izquierdo; tres no se encontraron. CONCLUSIÓN: Por su fácil acceso y simplicidad, el ultrasonido es el método de elección para localizar implantes profundos no palpables.

"Comparative intra- and inter-rater reliability of maximal voluntary contraction with unidigital and bidigital vaginal palpation and construct validity with Peritron manometer".

AIMS: Evaluate the intra- and inter-rater reliability of maximal voluntary contraction (MVC) of pelvic floor muscle (PFM) assessment by unidigital and bidigital vaginal palpation. As a secondary aim, evaluate the construct validity of vaginal palpation and a manometer. METHODS: A total of 120 women were recruited and allocated into three groups according to age (group 1 [G1]: 18-35; G2: 36-59; G3: ≥60 years). Examiner A conducted an interview and examiners B and C performed evaluations of PFM function using both unidigital and bidigital vaginal palpation. Seven to 10 days later, examiner B repeated both types of vaginal palpation and measured the MVC pressure with a Peritron. Reliability was analyzed using Cohen's linear weighted Kappa (κw ). The construct validity was calculated using the Spearman's correlation (rs ). RESULTS: Intra-rater reliability of unidigital and bidigital palpation was κw = 0.75 and κw = 0.58 in G1, κw = 0.59 and κw = 0.73 in G2, and κw = 0.79 and κw = 0.86 in G3, respectively. Inter-rater reliability of unidigital and bidigital palpation was κw = 0.52 and κw = 0.48 in G1, κw = 0.47 and κw = 0.52 in G2, and κw = 0.50 and κw = 0.64 in G3, respectively. Spearman's correlation coefficients were significant at rs = 0.79 and rs = 0.80 for unidigital and bidigital vaginal palpation, respectively. CONCLUSIONS: Unidigital or bidigital vaginal palpation were indicated to evaluate G1 and G2 but bidigital palpation was more reliable in G3 when two examiners performed the evaluation. For the assessment conducted by one examiner, unidigital palpation was more reliable in G1 while bidigital palpation was more reliable in G2 and G3. Both unidigital and bidigital palpation have high measures of validity.

Measuring Heart Rate During Exercise: From Artery Palpation to Monitors and Apps

The use of technology has increased tremendously, by means of more reliable, smaller, more accessible and specially more user-friendly devices, which provide a wider range of features, and promote significant benefits for the population and health professionals. It is in this context that monitors and apps for heart rate (HR) measurement have emerged. HR is a clinical vital sign of diagnostic and prognostic importance. In response to body movement, HR tends to increase, in a direct relationship with the intensity of exercise. HR was primarily measured by the count of arterial pulse, and recently, HR can be precisely measured by monitors, bracelets and smartphone apps capable to perform real-time measurements and storage of data. This paper aimed to make a brief and updated review on the theme, providing a broader view of advantages and limitations of these resources for HR measurement in exercise. HR monitors and apps use basically two types of technology, optical sensor (photoplethysmography) and electrical signal from the heart. In general, these devices have shown good accuracy in measuring HR and HR variability at rest, but there are differences between brands and models considering the type, mode and intensity of exercise. HR measurements by monitors and smartphone apps are simple, accessible and may help cardiologists in the monitoring of the intensity of aerobic exercise, focusing on health promotion and on primary and secondary prevention of cardiovascular diseases

Pelvic floor muscle training protocol for stress urinary incontinence in women: A systematic review.

INTRODUCTION: Strengthening exercises for pelvic floor muscles (SEPFM) are considered the first approach in the treatment of stress urinary incontinence (SUI). Nevertheless, there is no evidence about training parameters. OBJECTIVE: To identify the protocol and/or most effective training parameters in the treatment of female SUI. METHOD: A literature research was conducted in the PubMed, Cochrane Library, PEDro, Web of Science and Lilacs databases, with publishing dates ranging from January 1992 to March 2014. The articles included consisted of English-speaking experimental studies in which SEPFM were compared with placebo treatment (usual or untreated). The sample had a diagnosis of SUI and their age ranged between 18 and 65 years. The assessment of methodological quality was performed based on the PEDro scale. RESULTS: Seven high methodological quality articles were included in this review. The sample consisted of 331 women, mean age 44.4±5.51 years, average duration of urinary loss of 64±5.66 months and severity of SUI ranging from mild to severe. SEPFM programs included different training parameters concerning the PFM. Some studies have applied abdominal training and adjuvant techniques. Urine leakage cure rates varied from 28.6 to 80%, while the strength increase of PFM varied from 15.6 to 161.7%. CONCLUSION: The most effective training protocol consists of SEPFM by digital palpation combined with biofeedback monitoring and vaginal cones, including 12 week training parameters, and ten repetitions per series in different positions compared with SEPFM alone or a lack of treatment.

Sensitivity for palpating lumbopelvic soft- tissues and bony landmarks and its associated factors: A single-blinded diagnostic accuracy study.

BACKGROUND: Evidence on the diagnostic performance of palpatory methods and possible confounding factors is scarce. OBJECTIVES: To examine the sensitivity of palpatory methods for location of lumbopelvic landmarks and to assess its association with personal characteristics. METHODS: Eighty-three participants (41 men, 55.6 (16.5) years, 25.9 (4.8) kg/m2 [mean (SD)]) were enrolled in this single-blinded study. Fourteen body and softy-tissue landmarks were sequentially palpated from the spinous process of L4 to the ischial tuberosity. CT-scan images were used to assess what landmark was located. RESULTS: Sensitivity for location was in range 22-86% for soft-tissues and 26-69% for bony landmarks. Reduction in sensitivity was observed from the quadratus lumborum to the inferior and lateral angle of the sacrum (86-26% and 75-33%, left and right sides, respectively). Palpations of L4 and L5 spinous processes were systematically more cephalic than other landmarks. Gender was weakly correlated to almost all landmarks (rp⁢b= 0.333 or weaker). Body mass index was weakly correlated to the accurate location of ILAS and quadratus lumborum, great trochanter, PSIS, and piriformis (rp⁢b=-0.307 or weaker). CONCLUSIONS: Systematic and propagation errors were present using sequential palpatory methods. Palpation in men was more sensitive and higher BMI was associated with lower sensitivity for lumbopelvic landmarks.

The Clinical anatomy of the physical examination of the abdomen: A comprehensive review.

Physical examination of the abdomen is an essential skill. Knowledge of its clinical anatomy and application is vital for making diagnoses. Misinterpretation of anatomy during examination can have serious consequences. This review addresses understanding of the anatomy, methodology, and complications of abdominal physical examination. It includes particular reference to modern technology and investigations. Physical examination is performed for diagnostic purposes. However, the art of physical examination is declining as more and more clinicians rely on newer technology. This can have regrettable consequences: negligence, waste of time and resources, and deterioration of clinical skills. With a sound knowledge of clinical anatomy, and realization of the importance of physical examination of the abdomen, clinician, and patients alike can benefit. Clin.

Locating the Seventh Cervical Spinous Process: Accuracy of the Thorax-Rib Static Method and the Effects of Clinical Data on Its Performance.

OBJECTIVES: The aim of this study was to assess the thorax-rib static method (TRSM), a palpation method for locating the seventh cervical spinous process (C7SP), and to report clinical data on the accuracy of this method and that of the neck flexion-extension method (FEM), using radiography as the gold standard. METHODS: A single-blinded, cross-sectional diagnostic accuracy study was conducted. One hundred and one participants from a primary-to-tertiary health care center (63 men, 56 ± 17 years of age) had their neck palpated using the FEM and the TRSM. A single examiner performed both the FEM and TRSM in a random sequence. Radiopaque markers were placed at each location with the aid of an ultraviolet lamp. Participants underwent chest radiography for assessment of the superimposed inner body structure, which was located by using either the FEM or the TRSM. RESULTS: Accuracy in identifying the C7SP was 18% and 33% (P = .013) with use of the FEM and the TRSM, respectively. The cumulative accuracy considering both caudal and cephalic directions (C7SP ± 1SP) increased to 58% and 81% (P = .001) with use of the FEM and the TRSM, respectively. Age had a significant effect on the accuracy of FEM (P = .027) but not on the accuracy of TRSM (P = .939). Sex, body mass, body height, and body mass index had no significant effects on the accuracy of both the FEM (P = .209 or higher) and the TRSM (P = .265 or higher). CONCLUSIONS: The TRMS located the C7SP more accurately compared with the FEM at any given level of anatomic detail, although both still underperformed in terms of acceptable accuracy for a clinical setting.

Locating the Seventh Cervical Spinous Process: Development and Validation of a Multivariate Model Using Palpation and Personal Information.

OBJECTIVE: The aim of this study was to develop and validate a multivariate prediction model, guided by palpation and personal information, for locating the seventh cervical spinous process (C7SP). METHODS: A single-blinded, cross-sectional study at a primary to tertiary health care center was conducted for model development and temporal validation. One-hundred sixty participants were prospectively included for model development (n = 80) and time-split validation stages (n = 80). The C7SP was located using the thorax-rib static method (TRSM). Participants underwent chest radiography for assessment of the inner body structure located with TRSM and using radio-opaque markers placed over the skin. Age, sex, height, body mass, body mass index, and vertex-marker distance (DV-M) were used to predict the distance from the C7SP to the vertex (DV-C7). Multivariate linear regression modeling, limits of agreement plot, histogram of residues, receiver operating characteristic curves, and confusion tables were analyzed. RESULTS: The multivariate linear prediction model for DV-C7 (in centimeters) was DV-C7 = 0.986DV-M + 0.018(mass) + 0.014(age) - 1.008. Receiver operating characteristic curves had better discrimination of DV-C7 (area under the curve = 0.661; 95% confidence interval = 0.541-0.782; P = .015) than DV-M (area under the curve = 0.480; 95% confidence interval = 0.345-0.614; P = .761), with respective cutoff points at 23.40 cm (sensitivity = 41%, specificity = 63%) and 24.75 cm (sensitivity = 69%, specificity = 52%). The C7SP was correctly located more often when using predicted DV-C7 in the validation sample than when using the TRSM in the development sample: n = 53 (66%) vs n = 32 (40%), P < .001. CONCLUSIONS: Better accuracy was obtained when locating the C7SP by use of a multivariate model that incorporates palpation and personal information.

A Review of Simulators with Haptic Devices for Medical Training.

Medical procedures often involve the use of the tactile sense to manipulate organs or tissues by using special tools. Doctors require extensive preparation in order to perform them successfully; for example, research shows that a minimum of 750 operations are needed to acquire sufficient experience to perform medical procedures correctly. Haptic devices have become an important training alternative and they have been considered to improve medical training because they let users interact with virtual environments by adding the sense of touch to the simulation. Previous articles in the field state that haptic devices enhance the learning of surgeons compared to current training environments used in medical schools (corpses, animals, or synthetic skin and organs). Consequently, virtual environments use haptic devices to improve realism. The goal of this paper is to provide a state of the art review of recent medical simulators that use haptic devices. In particular we focus on stitching, palpation, dental procedures, endoscopy, laparoscopy, and orthopaedics. These simulators are reviewed and compared from the viewpoint of used technology, the number of degrees of freedom, degrees of force feedback, perceived realism, immersion, and feedback provided to the user. In the conclusion, several observations per area and suggestions for future work are provided.

Validation of palpatory methods for evaluating anatomical bone landmarks of the cervical spine: a systematic review.

OBJECTIVE: The aim of this study was to systematically review the literature for validity of palpatory procedures for evaluating anatomical bone landmarks in the cervical spine. METHODS: A systematic search of electronic databases identified observational studies assessing validity and/or accuracy regarding evaluation of anatomical bone landmarks of cervical spine palpatory procedures. The databases used in the search included the US National Library of Medicine of the National Institutes of Health (MEDLINE/PubMed), the Regional Library of Medicine (Bireme), the Scientific Electronic Library Online (SciELO), the Physiotherapy Evidence Database (PEDro), the Latin American and Caribbean Health Sciences Literature database (LILACS), the Cochrane Library, and Coordination of Personnel Improvement of Higher Education (CAPES/Brazil). Data were extracted by a primary reviewer, and 2 independent reviewers used a critical appraisal tool to estimate the quality of the retrieved studies. The results were synthesized qualitatively within the Quality Assessment of Diagnostic Accuracy Studies criteria. After completing the synthesis and scoring, the reviewers applied classifications such as "low," "fair," and "good." RESULTS: The initial search yielded 69860 articles. After selection criteria were applied, 5 studies satisfied the eligibility criteria. Three studies verified the validity of the manual palpatory procedure, and 2 studies correlated the findings of the palpatory procedures with other measured results. According to Quality Assessment of Diagnostic Accuracy Studies criteria, 3 studies presented good methodological quality, and 2 presented fair methodological quality. Studies demonstrated an accuracy range from 51% to 87.8%. CONCLUSION: There are few studies that evaluate the validity of manual palpatory procedures for examining boney landmarks of the cervical spine. The 5 that were found showed fair to good methodological quality. However, we note that there may be poor external validity due to the sampling heterogeneity of these studies.

Tumores retroperitoneales en la infancia / Retroperitoneal tumors in childhood

INTRODUCCIÓN: los tumores retroperitoneales se presentan con baja incidencia en la infancia, pero tienen muy alta letalidad. Aunque estos se clasifican en primarios y secundarios, y dependen en gran medida del tejido de origen, su forma quística o sólida, o su benignidad o malignidad en Pediatría, se presentan desde la etapa de recién nacido. OBJETIVO: determinar la incidencia de los tumores retroperitoneales en el Hospital Pediátrico Universitario Centro Habana, entre el 1º de enero de 2000 y el 31 de diciembre de 2012. MÉTODOS: se realizó un estudio descriptivo longitudinal retrospectivo de los 77 pacientes tratados en el centro con diagnóstico de tumores del retroperitoneo, entre el 1º de enero de 2000 y el 31 de diciembre de 2012. Se analizaron las variables edad, sexo, síntomas y signos, tipo de tumor y tratamiento. RESULTADOS: el 57 % era del sexo femenino, el 60 % tenía entre 0 y 5 años, el nefroblastoma se presentó en 50 %. El motivo de consulta fue dolor abdominal y fiebre (40 %), y el tumor fue palpable en el 80 %. La cirugía realizada fue resección total a todos los casos. Se constataron 39 nefroblastomas, 24 neuroblastomas y 6 carcinomas de células renales, entre otros. El neuroblastoma fue más frecuente en varones, y el nefroblastoma en hembras. En menores de 5 años fueron el nefroblastoma y el neuroblastoma. CONCLUSIONES: la ecografía abdominal detectó el tumor en todos los casos, por lo que es el examen de elección en la primera etapa de estudio. La rápida progresión de los tumores malignos en Pediatría, obliga a considerar la palpación de una masa abdominal como una urgencia pediátrica.

INTRODUCTION: the incidence of retroperitoneal tumors is low at childhood, but the fatality rate is very high. Although these tumors are classified into primary and secondary depending greatly on the tissue of origin, their cystic or solid form, benignancy or malignancy in pediatrics occurs since the neonatal phase. OBJECTIVE: to determine the incidence of retroperitoneal tumors in the university pediatric hospital of Centro Habana from January 2000 through December 2012. METHODS: a retrospective longitudinal and descriptive study of 77 patients who were treated at this center and diagnosed as retroperitoneal tumors from January 2000 through December 31st, 2012. The analysis variables were age, sex, symptoms and signs, type of tumor and treatment. RESULTS: in this group, 57 % were females, 60 % aged 0 to 5 years, and nephroblastoma was present in 50 % of cases. The reason for going to the doctor's was abdominal pain and fever (40 %) and the tumor was palpable in 80 %. Total resection was the elected surgery in all the cases. There were confirmed 39 nephroblastomas, 24 neuroblastomas and 6 renal cell carcinomas, among others. Neuroblastoma was the most frequent in boys whereas nephroblastoma was common in girls. In children aged under 5 years, nephroblastoma affected boys more and neuroblastoma was frequent in girls. CONCLUSIONS: nephroblastoma (39 cases) followed by neuroblastoma (24 cases) were the most common retroperitoneal tumors found at the university pediatric hospital of Centro Habana in the period of 2000 through 2012. Abdominal echography detected tumors in all the cases, so this is the test of choice in the first stage of the study. The rapid progression of malignant tumors in pediatrics leads to considering palpated abdominal mass as an emergency in pediatrics.
