[Arthroscopic biceps tenodesis with a «relaxed¼ technique.Clinical and radiological results of a prospective cohort]. / Tenodesis artroscópica del bíceps mediante técnica «relajada¼. Resultados clínicos y radiológicos de una cohorte prospectiva.

INTRODUCTION: in the treatment the long head of the biceps tendon (LHBT) pathology, the «relaxed tenodesis¼ is an arthroscopic articular suprapectoral tenodesis that seeks to lower the tension on the LHBT, and therefore, theoretically avoid persistent pain. OBJECTIVE: to assess clinical and radiological results of «relaxed¼ tenodesis in a prospective cohort of patient with work related illness. MATERIAL AND METHODS: prospective cohort, 54 shoulders with «relaxed¼ tenodesis performed with an intra-articular interference screw by the same surgeon, from October 2014 to 2018, in a level 1 trauma center. Demographic, clinical, functional and radiologic results were analyzed. On 6 months follow-up, a sonographic and clinical assessment was performed. RESULTS: mean age 49 ± 9, mean follow-up 16 ± 4 months. The main diagnosis was a rotator cuff tear in 79%, primary biceps pathology in 10% and other pathologies in 11%. At the end of follow-up, the cohort showed active anterior elevation 157.7 ± 22.7, external rotation 47 ± 16.6, median internal rotation T12, Constant Score 83 ± 12.05 points, subjective shoulder value 83 ± 12.97% and pain visual analogue scale 1.4 ± 1.7 points. One patient had a biceps tear and two had cosmetic arm asymmetry. On ultrasound 98% had the LHBT in situ and 10% had inflammatory changes on the bicipital groove. There were complications in 21% of the sample. CONCLUSIONS: «relaxed biceps tenodesis¼ is a technique that shows good clinical, functional and sonographic results, with low failure rate.

INTRODUCCIÓN: en el tratamiento de la patología del tendón de la cabeza larga del bíceps (TCLB) la tenodesis «relajada¼ es una tenodesis artroscópica suprapectoral alta, que busca disminuir la tensión del TCLB y, por tanto, el dolor persistente. OBJETIVO: evaluar resultados clínicos y radiológicos de la tenodesis «relajada¼ en una serie prospectiva de sujetos sometidos a compensación laboral. MATERIAL Y MÉTODOS: cohorte prospectiva de 54 hombros con tenodesis «relajada¼ con tornillo interferencial intraarticular, mismo cirujano, Octubre de 2014 a 2018, centro de trauma nivel 1. Se analizaron datos demográficos, resultados clínicos, funcionales y radiográficos. A los seis meses se realizó una ecografía de control y se evaluaron complicaciones. RESULTADOS: edad media 49 ± 9 años, seguimiento promedio 16 ± 4 meses. El diagnóstico primario fue rotura del manguito rotador en 79%, patología primaria del bíceps en 10% y otras patologías en 11%. Al término del seguimiento, la elevación anterior activa fue 157.7 ± 22.7, rotación externa 47 ± 16.6, rotación interna mediana T12, Constant Score 83 ± 12.05 puntos, valoración subjetiva del hombro 83 ± 12.97% y escala visual análoga del dolor 1.4 ± 1.7 puntos. Un paciente sufrió una rotura del bíceps y dos casos una asimetría estética del brazo. En ecografía, en 98% se visualizó el TCLB in situ y en 10% se objetivaron cambios inflamatorios en la corredera bicipital. Reportamos 21% de complicaciones. CONCLUSIONES: la tenodesis «relajada¼ presenta resultados clínicos, funcionales e imagenológicos satisfactorios, con baja tasa de fallo.

Intrathecal bupivacaine versus chloroprocaine for transvaginal cervical cerclage placement: a retrospective cohort study.

BACKGROUND: Bupivacaine is commonly used in spinal anesthesia for cervical cerclage placement, but its long duration of action can delay hospital discharge. Chloroprocaine has a short duration of action and has re-emerged as an agent for ambulatory neuraxial anesthesia. There are limited data comparing intrathecal bupivacaine and chloroprocaine when used for cerclage placement. This retrospective study compares the time to hospital discharge between these drugs when used in spinal anesthesia for cervical cerclage placement. METHODS: A retrospective analysis of patients who underwent transvaginal cerclage placement under neuraxial anesthesia with intrathecal hyperbaric bupivacaine or plain chloroprocaine between January 1, 2015 and October 31, 2020. The primary outcome was the time to hospital discharge. Secondary outcomes included the incidence of inadequate anesthesia, postoperative pain scores and postoperative neurologic symptoms. RESULTS: Three hundred and sixty patients were included in the final analysis (bupivacaine n=236, chloroprocaine n=124). The median (IQR) intrathecal dose was 7.5 (7.5, 9) mg and 45 (45, 50) mg in the bupivacaine and chloroprocaine groups respectively. The time (median [IQR]) from spinal anesthesia to hospital discharge was significantly shorter in the chloroprocaine group compared with the bupivacaine group (218 [180, 253] vs. 370 [309, 424] min, P<0.001). There were no significant differences between the groups for secondary outcomes and neither group had a patient report neurologic symptoms. CONCLUSION: When utilized in spinal anesthesia for transvaginal cervical cerclage placement, chloroprocaine may reduce the time to discharge while providing comparable anesthesia to that provided by bupivacaine.

[Swiss Confederation cooperation in health development: beginnings, experiences and present projects]. / Gesundheitliche Entwicklungszusammenarbeit des Bundes: Anfänge, Erfahrungen und die Projekte heute.

The types of medical and health activities in the first ten years of the Swiss Confederation's development aid program (1961-71) are examined in a critical light. In that period such aid was primarily in support of missionary hospitals in Africa and came to 3% of the total aid program of Switzerland. In the seventies guidelines for health programs were established and these have since been systematically applied. The principal aspects are: creation of basic health services, adaptation to local conditions, integration into the overall economic and social development efforts, training of health personnel. In conclusion, the article lists geographically those health projects, which are at present financed and/or staffed by DEH.
