Use of a novel shockwave trode results in better patient acceptance in awake canine patients treated for musculoskeletal disease.

Introduction: Extracorporeal shockwave therapy (ESWT) is used as a treatment option for several musculoskeletal pathologies in dogs. When performing ESWT using electrohydraulic devices, sedation is commonly recommended due to the noise and discomfort associated with the treatment. The aim of this study was to compare the tolerance of ESWT delivered by a standard or novel trode in awake canine patients with musculoskeletal disease. Materials and methods: This was a prospective, blinded clinical trial in which dogs with musculoskeletal disease received awake treatment with ESWT with a gradually increasing energy protocol using both standard and novel trodes with an electrohydraulic generator in a randomized fashion. Noise reactivity and tolerance to treatment as measured in number of shocks and energy level achieved were recorded. Results: Forty client-owned dogs with pathology affecting the hips, stifles, elbows, or shoulders were enrolled. Thirty-three dogs completed all three treatment sessions, three dogs completed two sessions, and four dogs completed one session. There was evidence of improved patient tolerability with the novel trode, based on an increased average number of shocks delivered (n ± SD = 848 ± 334 for novel trode; n ± SD = 767 ± 358 for standard trode; p = 0.0384) and higher average treatment energy level achieved (E ± SD = 6.5 ± 2.5 for novel trode; E ± SD = 5.3 ± 2.8 for standard trode; p = < 0.001). Decreased noise reactivity was found to be positively correlated with tolerability of shockwave treatment (energy level: p = 0.0168; number of shocks: p = 0.0097). Discussion: Administration of electrohydraulic ESWT is feasible in select awake patients using a gradually increasing energy protocol, and the tested novel shockwave trode is better tolerated than the standard trode. Further studies are required to determine the efficacy of the novel trode, and if gradually increasing energy protocols are clinically equivalent to current standard protocols that employ a consistent energy level.

Comparison of prevalence and severity of asthma among adolescents in the Caribbean islands of Trinidad and Tobago: results of a nationwide cross-sectional survey.

BACKGROUND: Asthma is a growing problem in the Caribbean but the prevalence in most islands is unknown and possible inter-island variation in prevalence has not been determined. A nationwide cross-sectional survey was conducted to compare the prevalence of asthma symptoms among high school students in the two islands of the Republic of Trinidad and Tobago. METHODS: Questionnaire and video instruments based on those developed by the International Study of Asthma & Allergy in Childhood (ISAAC) were used to assess asthma prevalence among 6394 children (age range, 11-19 years; mean age, 14.08 yrs) in the second and third years of 35 randomly selected high schools in Trinidad and Tobago. This cross sectional survey was conducted between September and December 2002. RESULTS: A total of 4988 questionnaires were available for analysis (3519 in Trinidad and 1469 in Tobago). Among respondents from the two islands, there were no significant differences in the prevalence of ever wheezing (24.1% and 24.3% for Trinidad and Tobago, respectively, RR 0.99, 95% CI, 0.90-1.08); wheezing in the previous 12 months (13.1% & 13.4%, RR 0.98, 95% CI 0.84-1.15); a previous or current diagnosis of asthma (12.8% & 13.5%, RR 0.95, 95% CI 0.82-1.12) and night cough in the past 12 months (35.4% & 38.3%, RR 0.93, 95% CI 0.86-1.00). However, symptoms of severe asthma were significantly more common among students from Tobago and included having had more than one acute attack in the past year (13.4% & 15.8%, RR 0.85, 95% CI 0.73-1.00, p = 0.0004), night waking as a result of wheeze (7.4% & 10.9%, RR 0.68, 95% CI 0.56-0.83, p < 0.0001) and speech limitation in the past year (5.2% & 8.7%, RR 0.59, 95% CI 0.47-0.74, p < 0.001) Exercise-associated wheezing was also more frequent among Tobagonian adolescents (17.5% & 20.2%, RR 0.87, 95% CI 0.76 - 0.98, p = 0.04). CONCLUSION: Self-reported wheeze is common among adolescents in Trinidad and Tobago. Variation in symptoms was found between the two territories; high school students from Tobago, the less industrialized of the two islands, reported more symptoms of severe asthma and exercise-induced wheeze. Difference in the ethnic composition rather than socio-economic factors may be contributing to the observed differences in symptom prevalence.

Smoking at home is strongly associated with symptoms of asthma and rhinitis in children of primary school age in Trinidad and Tobago.

OBJECTIVE: To compare, in the twin-island republic of Trinidad and Tobago, the prevalence of symptoms of asthma and rhinitis among children of primary school age who are exposed to household environmental tobacco smoke with the prevalence of these symptoms in their colleagues without this exposure. METHODS: Between September and December 2002, questionnaires based on the instrument developed for the International Study of Asthma and Allergies in Childhood (ISAAC) were distributed, via the children in their schools, to parents of 6,611 Year 2 pupils (typically 6 years old) or Year 3 pupils (typically 7 years old) in 106 randomly selected schools in Trinidad and Tobago (5,511 pupils on Trinidad and 1,100 pupils on Tobago). We added to the standard ISAAC questionnaires two questions, one on household smoking and one on the ethnicity of the children. RESULTS: A total of 3 170 completed questionnaires were suitable for further analysis (2,618 from Trinidad and 552 from Tobago). On Trinidad 782 of the children (29.9%) lived in homes where one or both parents smoked, and 513 (19.6%) had other relatives in the household who smoked. On Tobago 94 of the pupils (17.0%) had parents who smoked, and 84 (15.4%) came from homes where other residents smoked. Parental smoking was significantly associated with wheezing (odds ratio (OR): 1.43; 95% confidence interval (CI): 1.11-1.83), exercise-induced wheezing (OR: 2.12; 95% CI: 1.59-2.82), nocturnal coughing (OR: 1.64; 95% CI: 1.37-1.97), and symptoms of rhinitis (OR: 1.35; 95% CI: 1.10-1.65) in the last 12 months as well as a history of hay fever/sinus problems (OR: 1.39; 95% CI: 1.11-1.74). Smoking in the home by adult residents other than parents was also significantly associated with all of these symptoms as well as a history of asthma (OR: 1.49; 95% CI: 1.13-1.97). In terms of ethnic differences, parental smoking was most prevalent in the homes of South Asian students, while smoking by other adults in the home occurred most commonly in the households of pupils of mixed race. CONCLUSIONS: Even in Trinidad and Tobago, which is a tropical environment where more time is spent outdoors and homes have more open ventilation than in temperate climates, environmental tobacco smoke exposure is closely associated with an increased prevalence of symptoms of asthma and rhinitis in primary-school-aged children.

Smoking at home is strongly associated with symptoms of asthma and rhinitis in children of primary school age in Trinidad and Tobago

OBJETIVO: Comparar, en las dos islas que integran la república de Trinidad y Tabago, la prevalencia de síntomas de asma y de rinitis en escolares de primaria expuestos al humo de tabaco en el ambiente domiciliario con la prevalencia de los mismos síntomas en coetáneos sin la exposición. MÉTODOS: Entre septiembre y diciembre de 2002, se distribuyeron cuestionarios basados en el instrumento elaborado para el Estudio Internacional de Asma y Alergias en la Niñez (ISAAC, por International Study of Asthma and Allergies in Childhood). La distribución la efectuaron los escolares de 106 escuelas escogidas aleatoriamente en Trinidad y Tabago (5 511 escolares en Trinidad y 1 100 en Tabago) entre los padres de 6 611 escolares de segundo o tercer grado (por lo general de 6 y 7 años de edad, respectivamente). Añadimos dos preguntas al cuestionario ISAAC, una de ellas sobre el tabaquismo en el domicilio y la otra sobre el origen étnico de los niños. RESULTADOS: Un total de 3 170 cuestionarios llenados se prestaron a análisis (2 618 de Trinidad y 552 de Tabago). En Trinidad 782 (29,9%) de los niños vivían en hogares donde uno de los padres o ambos padres fumaban, y 513 (19,6%) tenían otros parientes en el domicilio que fumaban. En Tabago 94 de los niños (17,0%) tenían padres que fumaban y 84 (15,4%) venían de hogares donde otros residentes fumaban. El tabaquismo en los padres mostró una asociación significativa con la presencia de sibilancias (razón de posibilidades [RP]: 1,43; intervalo de confianza de 95% [IC95%]: 1,11û 1,83), sibilancias provocadas por el ejercicio (RP: 2,12; IC95%: 1,59û2,82), tos nocturna (RP: 1,64; IC95%: 1,37û1,97) y síntomas de rinitis (RP: 1,35; IC95%: 1,10û1,65) en los 12 meses más recientes, así como antecedentes de fiebre del heno o problemas sinusales (RP: 1,39; IC95%: 1,11û1,74). La presencia en el domicilio de parientes fumadores distintos de los padres también mostró una asociación significativa con todos estos síntomas y con antecedentes de asma (RP: 1,49; IC95%: 1,13û1,97). En cuanto a diferencias por razones étnicas, el tabaquismo de los padres fue más frecuente en los hogares de escolares del sur del Asia, mientras que el tabaquismo de otros adultos en el domicilio se observó con más frecuencia en los hogares de escolares de raza mixta...
