Tuberculosis infantil: presentación de 3 casos y discusión / Pediatric tuberculosis: case report and discussion

Se presentan tres casos de tuberculosis infantil. Los dos primeros casos son dos hermanos de 5 años y 20 meses de edad con tuberculosis pulmonar, contactos intradomiciliarios del caso índice, la madre de ambos afecta de tuberculosis pulmonar bacilífera, con antecedente de viaje hace 4 meses a su pais de origen (Marruecos); ambos diagnosticados por positividad de la prueba de tuberculina y estudio radiográfico. El tercero es una niña de 9 años afecta de artritis idiopática juvenil en tratamiento inmunosupresor que desarrolló tuberculosis miliar con afectación encefálica, diagnosticada inicialmente en contexto de estudio de adenopatía (AU)

Three cases of childhood tuberculosis are presented: first and second cases are two brothers of 5 years and 2.0 months old respectively with pulmonary tuberculosis, household contacts of the index case: their mother, who was affected by smear-positive pulmonary tuberculosis, four months after visiting their country of origin (Morocco); both brethren were diagnosed by positivity of the tuberculin test and radiographic study. The third case is a 9 ycar old girl, juvenile idiopathic arthritis patient treated With immunosuppressive therapy, who has developed miliary tuberculosis with meningoencephalic involvement and she was initially diagnosed by the study of an adenopathy (AU)

Cojera en una niña de 20 meses, ¿es siempre una sinovitis de cadera? / Lameness in a 20 months girl, is it always a synovitis of the hip?

La cojera o el dolor musculoesquelético es una consulta frecuente en la infancia. Su etiología es diversa y frecuentemente banal. En algunas ocasiones la cojera puede ser el síntoma inicial de procesos neoplásicos. Presentamos el caso de una lactante de 20 meses de edad que presentó una cojera de dos semanas de evolución. En la valoración inicial en Atención Primaria no se apreció patología de gravedad, se realizó una ecografía de caderas y fue diagnosticada de sinovitis transitoria. Tras un periodo de reposo relativo y antiinflamatorios no se apreció mejoría. Varias semanas después presentó dolor nocturno de extremidades de forma intermitente. Se realizó una analítica en la que se apreciaba una neutropenia. Ante la persistencia de la cojera, la presentación del dolor nocturno y la neutropenia, se procedió a derivar a la paciente al Servicio de Oncohematología de referencia donde se diagnosticó de leucemia linfoblástica aguda (AU)

Lameness or musculoskeletal pain is a frequent consultation in the infancy. Its etiology is diverse and frequently not severe. In some cases lameness can be the initial symptom of neoplasic processes. Caucasic woman aged 20 months who presented lameness of two weeks of evolution. In the initial evaluation in Health primary care center we didn't appreciate any severity process. An ultrasound scan of hips was realized and she was diagnosticated of transient sinovitis of the hip. After a period of relative rest and anti-inflammatory treatment medical staff didn't appreciate any improvement. Several weeks later she presented intermitent night pain in the legs. A blood sample was taken and discovered neutropaenia. Given the persistence of the lameness, night pain and neutropenia, paediatrician sent the patient to paediatric oncohematology department where the diagnosis of linfoblastic leukaemia was realized after bony marrow aspiration (AU)

Incidence of Fusarium oxysporum f. sp. lycopersici Races in Tomato in Sinaloa, Mexico.

Sinaloa State is the main producer of tomatoes (Solanum lycopersicum L) in Mexico where production attained 15,784 ha in 2008 (3). Fusarium wilt of tomato caused by Fusarium oxysporum f. sp. lycopersici (Sacc) Snyder & Hansen causes significant yield losses in Sinaloa each year (2). Three pathotypes or races of F. oxysporum f. sp. lycopersici have been described: races 1, 2, and 3 (1). The purpose of this study was to determine the races of F. oxysporum f. sp. lycopersici present in Sinaloa and distribution of these races in the region. F. oxysporum f. sp. lycopersici isolates were obtained from plants showing symptoms of yellowing and necrosis of vascular bundles. Plants were sampled from 50 fields throughout the production area in Sinaloa from November 2008 to March 2009. Four differential cultivars were used to identify the races of 26 F. oxysporum f. sp. lycopersici isolates collected across Sinaloa: Bonny Best (susceptible to all races), UC-82-L (susceptible to races 2 and 3), F1 MH-1 (susceptible to race 3), and IR-3 (resistant to all races). A microconidial suspension was prepared for each isolate (1 × 106 CFU/ml) from cultures grown in potato dextrose broth with constant agitation (110 rpm) at 28°C for 7 days. Five 25-day-old seedlings (three fully expanded true leaves) from each differential cultivar were immersed in the appropriate microconidial suspension for 10 min, then individually transplanted into a pot containing 1 kg of sterilized commercial potting mix, and grown in a growth chamber at 25 to 28°C and 60 to 75% relative humidity for 5weeks with 14-h light/10-h darkness. Control plants (root dipped for 10 min in sterile water) were grown similarly and remained asymptomatic. Susceptible cv. Bonny Best showed typical symptoms of Fusarium wilt including epinasty, yellowing, defoliation, vascular necrosis, and wilt. None of these plants survived 25 days postinoculation for any of the isolates. All UC-82-L plants inoculated with each of the 26 isolates died before 35 days, indicating that none of the isolates was of race 1. F1 MH-1 plants only survived inoculation with 3 of the 26 isolates (11.5%), indicating that the 23 isolates that killed these plants (88.5% of the 26 isolates) were of race 3, and only 3 isolates were of race 2. All IR-3 plants inoculated with the 26 isolates survived. The isolates showed variation in response to the differential cultivar UC-82L in duration from inoculation to when the plants died (variation in isolate aggressiveness). The three F. oxysporum f. sp. lycopersici race 2 isolates were restricted to the Culiacan Valley, whereas the 23 F. oxysporum f. sp. lycopersici race 3 isolates were widely distributed across Sinaloa. Koch's postulates were confirmed by reisolating the fungus from the roots and stem base of each dead, inoculated plant (4). This study provides baseline data for future surveys to monitor changes in distribution of F. oxysporum f. sp. lycopersici races in Sinaloa, Mexico. References: (1) G. Cai et al.

[Central sleep apnea syndrome as the first sign of type I Chiari malformation]. / Síndrome de apnea central del sueño como primera manifestación de malformación de Chiari tipo I.

INTRODUCTION: Type I Chiari malformation consists on the caudal displacement of cerebellar tonsils through the foramen magnum. It is often asymptomatic, although it may display symptoms as a result of cerebellum, brainstem, high cervical spinal cord or the lower cranial nerve, involvement. OBJECTIVE: We report our experience over the last 16 years. We have identified 16 patients with type I Chiari malformation. Only 2 cases showed common type I Chiari symptoms and just one had respiratory disorder as the first clinical sign. CLINICAL CASE: A 15 year old girl presented with a 5 years' history of chronic daily cough aggravated by exercise. Snoring and sleep apnea had been noted by her mother for 1 year. The girl eventually suffered from migraine and diurnal hypersomnolence. The physical and neurological examination was normal with the only exception being the absence of bilateral nauseous reflex. A nocturnal polysomnography study demonstrated a pseudoperiodic pattern with apnea pauses associated to cycles of deep breathing, resulting in severe gasometric repercussion and bradycardia. Magnetic resonance imaging of the brain showed Chiari I malformation. Non-invasive mechanical ventilation treatment significantly improved the clinical symptoms and gasometric analysis. DISCUSSION: Surgical posterior fossa decompression is discussed. Early decompression before appearance of irreversible neurological damage is recommended. It is associated with a significant reduction in the number of central apneas and sleep arousals. Surgical intervention is recommended in symptomatic patients and in cases of radiographic Chiari malformation or syrinx progression.

Síndrome de apnea central del sueño como primera manifestación de malformación de Chiari tipo I / Central sleep apnea syndrome as the first sign of type I Chiari malformation

Introducción: La malformación de Chiari tipo I consiste en el descenso de las amígdalas cerebelosas a través del foramen magno. Con frecuencia es asintomática, pero puede presentar clínica por afectación de cerebelo, troncoencéfalo, porción superior de la médula cervical y pares craneales bajos. Objetivo: Se presenta nuestra experiencia de 16 años con 16 casos de malformación de Chiari tipo I; sólo en 2 existen síntomas atribuibles a la anomalía de Chiari tipo I, y en una de ellas la primera manifestación clínica consistió en un trastorno respiratorio durante el sueño. Caso clínico: Niña de 15 años con tos crónica diaria, agravada con el ejercicio, de 5 años de duración. La madre observaba desde hacía 1 año que al dormir la niña roncaba y realizaba repetidamente pausas de apnea. Tenía cefaleas ocasionales e hipersomnolencia diurna. Las exploraciones física y neurológica fueron normales, salvo ausencia de reflejo nauseoso bilateral. El estudio polisomnográfico nocturno evidenció un patrón seudoperiódico con alternancia de pausas de apnea con ciclos de respiraciones profundas, con graves repercusiones gasométricas y sobre la frecuencia cardíaca. La resonancia magnética mostró anomalía de Chiari tipo I. La ventilación mecánica no invasiva supuso una mejoría clínica y gasométrica en la paciente. Discusión: La descompresión quirúrgica es discutida. Está indicada de forma precoz, antes de que aparezca daño neurológico irreversible. Se asocia con una reducción significativa en el número de apneas centrales y microdespertamientos. Se recomienda en casos sintomáticos o en casos con progresión radiológica de la anomalía de Chiari o de la siringomielia asociada (AU)

[Facial paralysis reported in a paediatric emergency department: actuation protocol reviewed and verified]. / Parálisis facial en urgencias de pediatría: actualización de nuestro protocolo y autoevaluación.

INTRODUCTION: As result of our aim to improve the quality standard of our emergency system, work has been carried out in relation to the development and monitorization of effective clinical protocols in the department of paediatric practice. PATIENTS AND METHODS: An evidence based review approach was taken to design a clinical protocol about Bell's palsy condition for the paediatric emergency department. Previous protocol approved in March 2003 was reviewed accordingly with the new designed protocol's quality standards. The Bell's palsy cases reported since March 2003 until June 2006 to paediatric emergency department were analyzed. RESULTS: A total of 27 patients affected by Bell's palsy were reported to the hospital's emergency department. Facial expression was described in 85.19% of the cases. Cranial nerves normal function was reported in 77.78%. Fundoscopic examination was described in 77.78% and otoscopic findings in 44.44%; the absence of herpes vesicles was analyzed only in 11.11%. All patients received steroid therapy (prednisone) and the treatment resulted in the complete recovery. The mean time to resolution was 58.6 days. CONCLUSIONS: In order to improve hospital's quality standards, clinical protocols should be designed and verified regularly to ensure the proper performance. Medical auditing also contributes to improve effectiveness in health attendance.

[Neurocysticercosis: an imported disease?]. / Neurocisticercosis: ¿una enfermedad importada?

BACKGROUND: Neurocysticercosis is the CNS involvement caused by Taenia solium larvae and the most frequent cerebral parasitation. It has a cosmopolitan distribution but endemic in the low income countries. The paper analizes the geographic origin, clinical characteristics of patients and the diagnostic and therapeutic modalities. PATIENTS AND METHOD: Retrospective revision of clinical files in patients with the diagnosis of neurocysticercosis between the period January 1990 to March 2000. RESULTS: Ten patients were included of which only one was of Spanish nationality. The others were immigrants or travellers to Central/South America (7), Africa (1) and South East Asia (1). Nine patients presented with convulsive crisis, generalized in 7 and 3 cases suffered headaches. The diagnosis was obtained through biopsy technique (3 cases) and the rest through CT scan or MR and serology. ELISA specific serology was positive in 60% of cases. Eight patients were treated with praziquantel or albendazol solely with good clinical evolution. CONCLUSIONS: Neurocysticercosis is prevalent among the immigrant population and in our case imported mostly from Latin America. Diagnosis is reached through imaging and serological techniques. Treatment with praziquantel or albendazol improves the clinical picture and controls the convulsive crisis.

[Behaviors and risk factors in a population of patients with sexually transmitted diseases (STDs)]. / Conductas y factores de riesgo en una poblacion de pacientes con E.T.S.

PIP: 300 men and women attending a municipal sexually transmitted disease clinic in Guatemala City voluntarily participated in an anonymous and confidential study to determine HIV seroprevalence among patients with sexually transmitted diseases and to identify risk practices. Two cases were confirmed, for a seropositivity rate of 0.7%. Subjects were aged 6-62 years, with 45% between ages 21 and 30. 80% were male. 42% were married or in union. 26% of those in union reported occasional relations with other persons. 69% of subjects had never used condoms in occasional relations. 58% reported sex with prostitutes at least once a month. 97% reported they were heterosexual, 1.7% bisexual, and 0.3% homosexual, although 19% reported at least one past homosexual episode. 90% reported having had a sexually transmitted disease. 53.0% reported having had gonorrhea; 39.0%, pubic lice; 29.7%, human papillomavirus; and 27.3%, chancroid. At the time of the survey, 21.0% had gonorrhea, 13.7% had genital herpes, 13.3% had chancroid, and 12.0% had human papillomavirus. 9.0% reported receiving one or two blood transfusions between 1980 and 1988, when screening of the blood supply began in Guatemala. Among other risk factors, 89.3% reported using alcohol, tobacco, marijuana, or other drugs. 1.3% reported using intravenous drugs. 95.7% knew about AIDS, but only half perceived themselves to be at risk. 34.3% reported sexual relations before age 15; 9.7%, a history of sexual abuse; 65.7%, sexual promiscuity; 69%, nonuse of condoms; and 58%, contact with prostitutes.^ieng
