Colchicine prolongs patency of myringotomy in an animal model

Objective

Chronic otitis media with effusion (COME) is a frequently observed condition in childhood. The most common and effective surgical therapy for COME is myringotomy with insertion of a ventilation tube (VT). Our aims were to investigate the combined effect of myringotomy and the topical application of Colchicine solution to the external ear canal for the prolongation of patency in the treatment of patients with COME and to evaluate the ototoxicity of Colchicine applied directly to the middle ear.

Methods

A prospective study on 47 ears in 26 fat sand rats was fashioned. In the first phase, solutions of different concentrations of Colchicine were applied to the middle ear cavity in order to determine the drug's ototoxicity, assessing inner ear function with ABR. In the second phase myringotomy was performed and a non ototoxic concentration of Colchicine applied to 12 external ear canals, while saline was applied to nine.

Results

In the first phase, Colchicine concentration of 0.1% and higher applied to the middle ear cavity caused an ABR threshold elevation. In the second phase, the mean closure time after 0.01% Colchicine application was prolonged to >2.14 weeks (P < 0.05).

Conclusion

Colchicine has a proven potential for prolongation of myringotomy patency when applied as a solution to the external ear as a 0.01% solution. Further investigations are required to validate these results in humans and to study the potential effect of repetitive Colchicine application on the duration of myringotomy patency for the treatment of COME.     

The Catz-Itzkovich SCIM: a revised version of the Spinal Cord Independence Measure

Purpose : To examine the suitability of the revised Spinal Cord Independence Measure, the Catz-Itzkovich SCIM, for evaluation of patients with spinal cord lesions, as compared to the original SCIM and to the Functional Independence Measure (FIM). Method : The revised SCIM was applied by paired independent teams of occupational therapists, physiotherapists and nurses and the FIM by a single nurse. The examiners assigned scores to the functional capabilities of 28 patients with spinal cord lesions. The scores by the revised SCIM were analysed for reproducibility as between the two teams of examiners (interrater reliability) and for their correlation with the FIM scores. Results : The frequency of identical scoring by two independent examiners (total agreement) was 80% or higher for 13/18 individual functions listed in the revised SCIM. In the self-care category it was 80-99%, as compared to 75-87% before revision. In neither bowel management nor bed mobility was there an increase over the original SCIM in the frequency of identical scores, despite rephrasing and restructuring of the scoring criteria. A high correlation was noted between the paired scores for all functions listed as well as for those comprising each of the four functional categories ( r = 0.90-0.96, p < 0.001). The total revised-SCIM scores were significantly correlated with those derived by the FIM ( r = 0.835, p < 0.001). Conclusions : The findings indicate that the newly revised SCIM (Catz-Itzkovich) is a valid and highly reproducible measure of daily function in patients with spinal cord lesions, and is superior to the original SCIM. We recommend that it supersede the original SCIM.     

Obstetrical and Newborn Outcomes Among Patients With SARS-CoV-2 During Pregnancy

We report on the perinatal outcomes of pregnant patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from 2 hospitals in Montréal, Québec. Outcomes of 45 patients with SARS-CoV-2 during pregnancy were compared with those of 225 patients without infection. Sixteen percent of patients with SARS-CoV-2 delivered preterm, compared with 9% of patients without (P = 0.28). Median gestational age at delivery (39.3 (interquartile range [IQR] 37.7–40.4) wk vs. 39.1 [IQR 38.3-40.1] wk) and median birth weight (3250 [IQR 2780-3530] g vs. 3340 [IQR 3025-3665] g) were similar between groups. The rate of cesarean delivery was 29% for patients with SARS-CoV-2. Therefore, we did not find important differences in outcomes associated with SARS-CoV-2. Our findings may be limited to women with mild COVID-19 diagnosed in the third trimester.     

Effects of a fundholding discontinuation. An Israeli Health Maintenance Organization natural experiment

Objective - To evaluate the effects of fundholding on cost containment and after termination of the project. Design and setting - Primary care practices participating in the project were allocated an itemized budget. Practices assumed authority for hospitalization, drugs, ambulatory medical diagnostic, consultant services and acquisition of minor equipment. Financial incentives were offered, but no penalties were imposed on practices where expenditure exceeded budget. Subjects - Nine primary care practices in southern Israel. Main outcome measure - Total expenditure and a breakdown of expenditure per capita. Results - Fundholding practice expenditure was compared with expenditure in the district as a whole. During the study period, total expenditure in fundholding practices rose by 12%, whereas that of the district rose by 37%. With discontinuation of the project, expenditure of the designated practices returned to the original levels, equivalent to those of the district. Conclusion - Fundholding is an efficient method of cost-containment. The effect will be long lasting only if motivation is maintained.
