Hand Deformities

Radial club hand deformities are commonly treated with arthrolysis to allow centralization of the ulna. In this retrospective cohort study of 31 hands in 28 patients, we aimed to assess the outcomes of correction using progressive distraction and subsequent percutaneous pinning of the wrist with a corrective ulnar osteotomy. Mean follow-up time was 7 years (range 2 to 20). The angulation of the hand–forearm complex was decreased after each step of the procedure. Mean correction of the angulation was 64°, and the residual total forearm–hand angulation was 12° after completion of the surgery. At the time of bony maturity (four patients), all wrists had fused. Fifty-eight reoperations were required in 31 wrists because of pin migration or breakage, and in addition 18 secondary osteotomies of the ulna were performed. From this study we conclude that distraction and pinning provide satisfactory and stable realignment of the wrist to correct the deformity, but this treatment has drawbacks regarding the high number of reoperations and the loss of wrist mobility.

Lost To Follow Up

This is a retrospective cohort study using notification data in South Korea. We evaluated the nationwide status, regional differences, and the determinants of treatment outcomes among tuberculosis patients. Treatment success rate improved from 77.0% in 2012 to 86.0% in 2015. The lost to follow-up rate was higher among older people, males, and foreign nationals. Health care facilities designated for the Public-Private Mix (PPM) project showed higher success rate and lower rate of lost to follow-up. Moreover, municipalities with low regional deprivation index had higher PPM project coverage. Since there is a large regional difference in the coverage of the PPM project, an additional community-based support program should be implemented, especially for tuberculosis patients residing in region with low PPM project coverage.

ObjectivesMany researchers have expected pioglitazone to serve as an effective neuroprotective agent against Parkinson’s disease (PD). Therefore, we conducted this cohort study to investigate the association between pioglitazone use and PD by using a large Asian population-based dataset in Taiwan.DesignRetrospective cohort study.SettingTaiwan.Participants7906 patients with diabetes who had received pioglitazone were defined as the study cohort, and 7906 matched patients with diabetes who had not received pioglitazone were defined as the comparison cohort.Primary and secondary outcome measuresWe tracked each patient individually over a 5-year follow-up period to identify those diagnosed as having PD during this period. We performed Cox proportional hazard regression analyses to evaluate the HRs for PD between the study and comparison cohorts.ResultsThe findings indicated that among the sampled patients, PD occurred in 257 (1.63%): 119 (1.51%) pioglitazone users and 138 (1.75%) non-users. The adjusted HR for PD within the follow-up period was 0.90 (95% CI: 0.68 to 1.18) in the patients who had received pioglitazone compared with the matched patients who had not received pioglitazone. Moreover, this study revealed that pioglitazone use was not associated with PD incidence in men (HR: 1.06, 95% CI: 0.71 to 1.59) or women (HR: 0.84, 95% CI: 0.61 to 1.15).ConclusionsThis study did not find the relationship between pioglitazone use and PD incidence, regardless of sex, among an Asian population of patients with diabetes.
