Aims: Pain diagnoses in the 10th version of the International Classification of Diseases (ICD-10) did not adequately support the current management of pain. Therefore, we aimed to review the new 11th revision (ICD-11) in order to analyze its usefulness for the management, coding, research and education of chronic pain from a Latin American perspective. Methods: The Latin American Federation of Associations for the Study of Pain convened a meeting of pain experts in Lima, Peru. Pain specialists from 14 Latin American countries attended the consensus meeting. Results: In ICD-11, chronic pain is defined as pain that persists or recurs longer than 3 months and is subdivided into seven categories: chronic primary pain and six types of chronic secondary pain. Chronic primary pain is now considered a disease in itself, and not a mere symptom of an underlying disease. Conclusion: The novel definition and classification of chronic pain in ICD-11 is helpful for better medical care, research and health statistics. ICD-11 will improve chronic pain management in Latin American countries, for both the pain specialist and the primary care physician.

Las sibilancias recurrentes del pre escolar es una condición frecuente a la que se ve enfrentado el pediatra. La gran mayoría de estos pacientes presentan sibilancias en relación a infecciones respiratorias virales y solo una minoría de ellos tendrá diagnóstico de asma en la edad escolar. El enfrentamiento adecuado de estos niños se inicia con una detallada anamnesis y examen físico para descartar causas secundarias, lo que se complementa con algunos exámenes de laboratorio. La decisión de iniciar tratamiento de mantención dependerá principalmente de la frecuencia y gravedad de los episodios de sibilancias. Este tratamiento debe ser considerado como una prueba terapéutica, evitando su mantención por tiempos prolongados. Se recomienda el uso de corticoides inhalados en dosis bajas y realizar un seguimiento estrecho del paciente para objetivar la respuesta. En el caso de los episodios agudos los broncodilatadores son el tratamiento de elección, mientras que los corticoides sistémicos debieran reservarse solo para los casos severos o que requieren hospitalización.

Bronchial asthma is the most prevalent chronic condition among children, however, in Chile, it is underdiagnosed. This may be due to medical professionals failing to recognize the disease. It is essential to be aware of the symptoms and signs that are suggestive of the disease in order to begin an appropriate treatment to achieve disease control. Asthma must be suspected in school age children who present repeated episodes of bronchial obstruction. The diagnosis should be confirmed with lung function tests that demonstrate variable airflow obstruction with a positive bronchodilator response. Treatment is based on two fundamental pillars: education and pharmacological treatment. Educational activities must include: information about the disease and its treatment, regular monitoring of treatment adherence, teaching and reviewing the correct inhalation technique at every checkup, developing a personalized written action plan and scheduling regular follow-up appointments. The gold standard for treatment is maintenance inhaled corticosteroids, in the lowest possible dose that enables disease control. The goal of the treatment is to eliminate daily symptoms and asthma crisis. Therapy should be increased if control is not achieved, but before starting it, adherence to maintenance treatment, inhala-tion technique, presence of associated comorbidities and environmental exposure should be evaluated. In the mild patient, who is not receiving maintenance therapy, rescue treatment should be done with bronchodilators, always associated with inhaled corticosteroids. This consensus is a guide to improve the diagnosis, treatment and control of asthma in schoolchildren

Latin-American experts in the use of opioids in patients with chronic nononcologic pain (CNOP) have updated existing recommendations to current Latin-American reality. Several key opinion leaders from Latin America participated in a face-to-face meeting in Guatemala (April 2015) to discuss the use of opioids in CNOP. Subgroups of experts worked on specific topics, reviewed the literature and shaped the final manuscript. The expert panel developed guidelines taking into consideration the utility of both opioid and nonopioid analgesics and factors pertaining to their efficacy, safety, adherence, administration and risks for abuse/addiction. Latin-American guidelines for the use of opioids in CNOP should improve pain relief and patients' quality of life by increasing access to these effective agents.

Preschool wheezing is one of the most common presenting symptoms in pediatric practice. The vast majority of these patients present wheeze triggered by viral respiratory infections and only a minority of them will have asthma in school age. The evaluation of these children begin with a detailed clinical history and physical examination and standard laboratory tests to rule out secondary causes of wheezing. The decision for controlling therapy will depend on the frequency and severity of the wheezing episodes, but should always be considered as a treatment trial, avoiding prolonged periods of time. It is recommended to start with low doses of inhaled corticosteroids, evaluating treatment effect with a close follow up. Inhaled bronchodilators remain the treatment of choice in acute exacerbations of wheezing, systemic corticosteroids should be reserved for severe exacerbations in hospitalized patients.

We determined the prospective 10-year association among incident fragility fractures and four glucocorticoid (GC) treatment groups (Never GC, Prior GC, Baseline GC, and Ever GC). Results showed that GC treatment is associated with increased 10-year incident fracture risk in ambulatory men and women across Canada. Using the Canadian Multicentre Osteoporosis Study dataset, we determined the prospective 10-year association between incident fragility fractures and GC treatment. We conducted a 10-year prospective observational cohort study at nine sites across Canada. A total of 9,263 ambulatory men and women 25 years of age and older were included in the analysis. Multivariable Cox proportional hazards analyses were conducted to determine the relationship among GC treatment groups in four levels that included Never GC, Prior GC, Baseline GC, and Ever GC (combined baseline and prior groups) and time to fracture. In each of the Never GC, Prior GC, Baseline GC, and Ever GC treatment groups, the number of participants were 8,832 (95.4 %), 303 (3.3 %), 128 (1.4 %), and 431 (4.7 %), respectively. Of the 9,263 individuals enrolled, incident fragility non-spine, hip, spine, and any fractures were experienced by a total of 896 (9.67 %), 157 (1.69 %), 130 (1.40 %), and 1,102 (11.90 %) over 10-years, respectively. For men and women combined, prior GC treatment was associated with a higher hazard ratio (HR) for time to incident non-vertebral (HR = 1.5, 95 % confidence interval [CI] = 1.1, 2.0), hip (HR = 2.1, 95 % CI = 1.1, 4.0), and any fracture (HR = 1.4, 95 % CI = 1.0, 1.8) compared with never GC treatment. GC treatment is associated with increased 10-year incident fracture risk; this highlights the importance of considering therapy to prevent GC-induced fractures for patients who are using GC for various medical conditions.

Cushing's syndrome is a rare disease. Most patients have a hypophyseal tumor and the treatment is neurosurgical. A small percentage of patients require bilateral adrenalectomy. This paper reports the cases of two patients undergoing bilateral simultaneous laparoscopic surgery with excellent results.Under general anesthesia, with the patient in the lumbotomy position right adrenalectomy was performed first. 15 mm Hg Pneumoperitoneum was started with the Verres needle in the ipsilateral upper quadrant; four trocars were placed, two 10 mm and two 5 mm. In both cases the adrenal vein was divided between metallic clips. Once dissection was completed the gland was placed in a plastic bag and extracted through one of the trocar incisions. For the left side the position of the patient was changed, and the same procedure was performed using three trocars, two 10 mm and one 5 mm. No drainage was employed in either patient.The procedures were successfully performed without conversion. Surgical time was 150 minutes for the first patient and 210 for the second. Mean estimated blood loss was 125 ml. Mean hospital stay was 2.5 days. Both patients had a clinical reversion and they are managed with oral corticoid supplements.The results show that laparoscopic access to the adrenal gland is the approach of choice with very satisfactory outcomes for both patients and medical team.

We report a 27 years old male, treated with Indinavir as a prophylactic anti-HIV agent, who consulted for left ureteral pain. Intravenous and retrograde pyelograms disclosed a radioluscent stone, that was removed surgically. The physical-chemical study of the stone, demonstrated indinavir sulphate crystals.

A 27 years old female presented with diffuse abdominal pain, malaise, weight loss and a palpable mass in the left abdomen. Abdominal CAT scan showed a 18 cm heterogeneous tumoral mass that originated in the kidney. The patient was operated on and it was not possible to completely remove the mass. In the postoperative period the patient received chemotherapy with vincristine, cyclophosphamide and adryamicin but the disease progressed and the patient died 16 months later. The pathological study of the surgical specimen disclosed a tumor with monotonous proliferation of small round cells with a basophilic nucleus and scanty cytoplasm with PAS positive granules. Immunohistochemistry was positive for specific neuronal enolase and CD99. Involvement of the urinary system with primary neuroectodermal tumors is very infrequent.
