Acute abdomen secondary to complete tubular colonic duplication.

We report the case of a 6-month-old infant who presented with a complete duplication of the large intestine, debuting clinically with acute abdomen and severe metabolic disorders. We discuss the pathogenesis and morphology of the lesions, diagnostic difficulties and peculiarities of surgical treatment.

[Analysis of the medical decision in abdominal pain suggestive of acute appendicitis].

Objectives: Application of the theorem of Bayes for the study of the usefulness of complementary quantitative and qualitative assessment of the effectiveness of ultrasound diagnosis in order to provide the clinician with a tool to accurately assess the effectiveness of these tests in diagnosing abdominal pain appendix subject box.

Methods: Retrospective cohort of 184 patients treated from January 2009 to June 2010 for abdominal pain suggestive of acute abdomen, of which 145 were operated. Were established as predictors of appendiceal disease abdominal exploration, ultrasonography and plasma levels of CRP and leukocytes.

[Surgical stress and hypophyseal-adrenal activation in childhood].

Introduction: The study on the physiological alterations due to surgical aggression (surgical stress), widely investigated in adults, is less known in paediatric age.

The Objective: Of this work is to quantify surgical stress (evaluated by means of Oxford Scale as high or low depending on its value bigger or lower than 6), after determining changes of plasmatic concentrations of ACTH, beta-endorphin and cortisol in operated children.

Patients And Methods: Observational analytic design of a prospective cohort with internal comparison of the groups.

[Cancer-cryptorchism meta-analysis].

Introduction: Testicular cancer in adult and young patients with cryptorchidism (operated or not operated on) has been reported previously, but its epidemiological impact (as concept to profile cancer and/or therapeutical result of cryptorchidism based on quantitative dates) is not defined actually.

Objective: Determination by quantitative meta-analysis of the strength of relation (relative risk = RR) cancer and cryptorchidism and by qualitative meta-analysis of factors of cryptorchidism (anatomical position of teste, age of intervention, testicular biopsy) associated to cancer.

Results: Case-control and cohort studies of medical literature have been included in this report.

Hormonal response to surgical stress in schoolchildren.

Purpose: To determine hormone concentrations (ACTH, cortisol, beta-endorphin) in children before and after surgery, to assess the correlation between any hormonal changes and to study the influence exercised on them by the severity of surgical stress and the elective/emergency nature of the surgery.

Patients And Methods: Prospective cohort of 78 children (age= 10+/-2.6 years, range 6-13 years) undergoing elective or emergency surgery.
