Six-year clinical evaluation of iRoot BP Plus as apical barrier in permanent teeth of periapical periodontitis.

The apical barrier technique in permanent teeth with extensive destruction of the periapical tissue and a long infection time is much more difficult to succeed, which is a clinical challenge. This study aimed to evaluate the long-term effects of iRoot BP Plus as an apical material in adult teeth. Fifty incisors and premolars were chosen for this study. All teeth were performed apical barrier with the same operator. After treatment, the teeth were clinically and radiographically evaluated at 1, 2 and 6 years. At the 1-year follow-up, 35 teeth had healed, and three patients developed an apical abscess due to root fracture at the 2-year follow-up. Six years postoperatively, one tooth showed root resorption, which was considered a failure. The long clinical evaluation confirmed that iRoot BP Plus is a suitable material for the apical barrier of mature teeth with open apices and periapical lesions.

Construction of a follow-up evaluation index system for "Diagnosis of Brucellosis" (WS 269-2019) based on Delphi method and analytic hierarchy process / 中华地方病学杂志

Objective:To construct a follow-up evaluation index system for "Diagnosis of Brucellosis" (WS 269-2019), and provide a reference basis for the next revision and improvement of the standard.Methods:The evaluation index system for "Diagnosis of Brucellosis" (WS 269-2019) was preliminarily established by consulting relevant references and materials. The experts in the field of diagnosis, treatment, prevention and control of brucellosis were selected, and two rounds of expert consultation were carried out in the form of questionnaires using the Delphi method. The necessity and availability of evaluation indicators were scored, and suggestions for modifying and adding indicators were put forward. Based on this, a standard follow-up evaluation index system was established. At the same time, a judgment matrix was constructed combined with the Saaty scale, and the analytic hierarchy process was used to calculate the weight of each index in the system.Results:After 2 rounds of expert ( n = 10) consultation, a standard follow-up evaluation index system for "Diagnosis of Brucellosis" (WS 269-2019) was constructed with 3 first-level indexes, 8 second-level indexes and 21 third-level indexes. The positive coefficients of experts in 2 rounds of questionnaires were both 100%; the coefficient of authority of experts was 0.82; the Kendall's coefficients of concordance of first-level, second-level and third-level indexes were 0.722, 0.260, and 0.181, respectively, with P < 0.05. Among the first-level indexes, the weight of standard quality evaluation was the highest (0.364), and the weight of standard implementation status was the lowest (0.278); among the second-level indexes, the combined weight of social benefits was the highest (0.186), and the combined weight of advanced nature was the lowest (0.043); among the third-level indexes, the combined weight of timely diagnosis rate was the highest (0.096), and the combined weight of consistency with technical data was the lowest (0.009). Conclusions:The constructed follow-up evaluation index system for "Diagnosis of Brucellosis" (WS 269-2019) is scientific and reliable, which evaluated qualitatively and quantitatively, reduces the defects of a single evaluation, and provides a basis for subsequent revision and improvement of the standard.

Outcomes following arthroscopic transosseous equivalent suture bridge double row rotator cuff repair: a prospective study and short-term results.

BACKGROUND: The transosseous-equivalent cross bridge double row (TESBDR) rotator cuff (RC) repair technique has been developed to optimize healing biology at a repaired RC tendon insertion. It has been shown in the laboratory to improve pressurized contact area and mean foot print pressure when compared with a double row anchor technique. Pressure has been shown to influence healing between tendon and bone, and the tendon compression vector provided by the transosseous-equivalent suture bridges may enhance healing. The purpose was to prospectively evaluate the outcomes of arthroscopic TESBDR RC repair. METHODS: Single center prospective case series study. Sixty-nine patients were selected to undergo arthroscopic TESBDR RC repair and were included in the current study. Primary outcome measures included the Oxford Shoulder Score (OSS), the University of California, Los Angeles (UCLA) score, the Constant-Murley (CM) Score and Range of motion (ROM). Secondary outcome measures included a Visual Analogue Scale (VAS) for pain, another VAS for patient satisfaction from the operative procedure, EuroQoL 5-Dimensions Questionnaire (EQ-5D) for quality of life assessment. RESULTS: At 24 months post-operative, average OSS score was 44, average UCLA score was 31, average CM score was 88, average forward flexion was 145°, average internal rotation was 35°, average external rotation was 79°, average abduction was 150°, average EQ-5D score was 0.73, average VAS for pain was 2.3, and average VAS for patient satisfaction was 9.2. CONCLUSION: Arthroscopic TESBDR RC repair is a procedure with good post-operative functional outcome and low re-tear rate based on a short term follow-up.

Differences in response rates between mail, e-mail, and telephone follow-up in hand surgery research.

BACKGROUND: There is a need to determine the difference in response to mail, e-mail, and phone in clinical research surveys. METHODS: We enrolled 150 new and follow-up patients presenting to our hand and upper extremity department. Patients were assigned to complete a survey by mail, e-mail, or phone 3 months after enrollment, altering the follow-up method every 5 patients, until we had 3 groups of 50 patients. At initial enrollment and at 3 month follow-up (range 2-5 months), patients completed the short version of the Disabilities of the Arm, Shoulder, and Hand questionnaire (QuickDASH), the short version of the Patient Health Questionnaire (PHQ-2), the Pain Self-Efficacy Questionnaire (PSEQ), and rated their pain intensity. RESULTS: The percent of patients that completed the survey was 34 % for mail, 24 % for e-mail, and 80 % for phone. Factors associated with responding to the survey were older age, nonsmoking, and lower pain intensity. Working full-time was associated with not responding. CONCLUSIONS: The response rate to survey by phone is significantly higher than by mail or e-mail. Younger age, smoking, higher pain intensity, and working full-time are associated with not responding. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic I.

Complicaciones tardías en cohorte de lesionados medulares traumáticos de origen laboral / Late complications in a cohort of work related traumatic spinal cord injured patients

Introducción: Las complicaciones tardías en el lesionado medular (LM) son frecuentes, pesquisables y prevenibles mediante un programa de seguimiento. Objetivo: Determinar las complicaciones tardías que presentan los LM atendidos en Hospital del Trabajador (HT) de Asociación Chilena de Seguridad (ACHS), sometidos a programa de control de seguimiento, que viven en regiones rurales lejanas de Santiago. Pacientes y Métodos: Se evaluaron los pacientes LM en control de seguimiento en HT ACHS entre 2000 y 2006, a los que se les realizó evaluación multidisciplinaria, estudios de pesquisa de laboratorio, imaginología y entrevista de enfermería. El análisis estadístico se realiza por pruebas paramétricas. Resultados: Se controlaron 78 pacientes, 74 hombres y 4 mujeres, edad 48,7 +/- 11,8 años; la LM más frecuente fue paraplejia completa (52,6 por ciento). Todos los pacientes presentaron alguna complicación durante el período observado. Las complicaciones más frecuentes fueron dislipidemia (80,8 por ciento), dolor (71,8 por ciento), espasticidad (53,8 por ciento), infección urinaria (52,6 por ciento), constipación (48,7 por ciento) e insomnio (46,2 por ciento). 33,3 por ciento de los pacientes presentaron úlceras por presión. La prevalencia de diabetes mellitus fue 10,2 por ciento. Mediante ecografía abdominal se pesquisó 24,4 por ciento de colelitiasis y 24,4 por ciento de hígado graso. Discusión: La incidencia acumulada complicaciones tardías en los LM de nuestra cohorte es muy similar al descrito previamente, existiendo mayor frecuencia de enfermedades crónicas no trasmi-sibles (ECNT) que en la población general, debido a disminución de actividad física y alteración del metabolismo de lípidos y carbohidratos. Conclusiones: La alta incidencia acumulada de complicaciones tardías en LM recomienda desarrollar programas de evaluación de seguimiento multidisciplinario que permitan detectarlas precozmente.

Introduction: Late complications in spinal cord injured (SCI) are common, detectable and preventable by a follow up program. Aim: To determine late complications suffered by SCI treated at Hospital del Trabajador (HT) of Asociación Chilena de Seguridad (ACHS), subject to follow-up evaluation program and living in distant rural areas of Santiago. Patients and Methods: Patients evaluated in follow-up evaluation program of HT ACHS between 2000 and 2006 who underwent multidisciplinary evaluation, laboratory studies and imaging research and nursing interview. Statistical analysis was performed by parametric tests. Results: 78 patients were monitored, 74 men and 4 women, age 48.7 +/- 11.8 years; the most frequent SCI was complete paraplegia (52.6 percent). All patients had complications during the observation period. The most frequent complications were dyslipidemia (80.8 percent), pain (71.8 percent), spasticity (53.8 percent), uri-nary tract infection (52.6 percent), constipation (48.7 percent) and insomnia (46.2 percent). 33.3 percent of patients had pressure ulcers. The prevalence of diabetes mellitus was 10.2 percent. Abdominal ultrasound detected 24.4 percent of gallstones and 24.4 percent of fatty liver. Discussion: The incidence of late complications in our SCI cohort is very similar to that described previously, existing more frequent in chronic diseases than in the general population, due to decreased physical activity and altered lipid and carbohydrate metabolism. Conclusions: High incidence of late complications in SCI recommends develop a multidisciplinary evaluation program and screening tests to early detection of them.
