Purpose To introduce a modified frontalis muscle (FM) flap for use in FM flap advancement surgery and compare it with the conventional flap for correcting severe congenital ptosis. Methods This retrospective cohort study included 200 patients (278 eyes) with severe congenital ptosis treated with FM flap advancement at Tianjin Eye Hospital from April 2018 to October 2019. The patients were divided into two groups: 100 patients (138 eyes) in the conventional group and 100 patients (140 eyes) in the modified group. The success and complication rates were evaluated. Results The final success rate was 77.5% (107/138) in the conventional group and 90.0% (126/140) in the modified group (p = 0.005). Undercorrection was observed in 31 eyes (22.5%) in the conventional group and 14 eyes (10%) in the modified group (p = 0.005). In the conventional group, angular deformity of the upper eyelid was observed in 29 eyes (21.0%), FM paralysis in 11 (8.0%), frontal hypoesthesia in 10 (7.2%), severe hematoma in 12 (8.7%), and exposure keratitis in 8 (5.8%); these complications were not observed in the modified group (p <0.001, p <0.001, p = 0.004, p <0.001, p = 0.011, respectively). There were no cases of overcorrection, entropion or ectropion in either group. Conclusion Compared with the conventional FM flap, the modified FM flap in this study yielded a higher success rate with a clear field of vision, mild trauma, and few complications. This technique is simple and convenient for correcting severe congenital ptosis.

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.

Introduction Critical weight loss is defined as an unintentional weight loss of ≥ 5% at 1 month or ≥ 10% at 6 months from the start of treatment. Critical weight loss leads to deterioration of the immune function and reduced tolerance to treatment (surgery ± radiochemotherapy) as well as increased complication rates. Objective Critical weight loss, defined as a weight loss of ≥ 5% after 1 month or ≥ 10% after 6 months from the start of treatment, is not uncommon in head and neck cancer patients. We aimed to assess the factors associated with critical weight loss during the treatment of oral cavity squamous cell carcinoma patients. Methods A retrospective cohort study was performed at the Aga Khan University Hospital, in Karachi, Pakistan, on 125 patients. Patients receiving adjuvant therapy were considered exposed, and the outcome was critical weight loss. Results The mean age of presentation was 46.9 ± 12.8 years in patients undergoing surgery and adjuvant therapy, with 119 (79.3%) of them being male and 31 (20.7%) female. One hundred and twelve patients (81.3%) developed critical weight loss at 6 months from the start of treatment, and the only significant variable associated with critical weight loss was the stage of the disease (p = 0.03). Conclusion A large proportion of patients with oral cancer developed critical weight loss requiring a need for intervention. The overall stage of the disease is a significant predictor of critical weight loss in patients undergoing treatment.

Abstract Background Tuberculosis (TB) and HIV are one of the significant public health problems in Thailand, and an estimated 15,000 individuals have a dual infection. Both HIV and TB each disease speeds up the progression of each other. TB is the leading cause of death in HIV-infected individuals, and HIV coinfected TB patients have disease-specific, and treatment affected their treatment outcomes. There is insufficient evidence on issues of TB and HIV co-infection patients received treatment. This study aimed to assess the impact of HIV status on treatment outcome of TB patients. Methods We conducted a retrospective cohort study among TB patients who registered to service at Chaophraya Abhaibhubejhr Hospital, Prachin Buri, Thailand from October 1, 2017 to October 31, 2018. All patients’ demographic data, diagnosis, and treatment were retrieved. Clinical characteristics, treatment outcome, and factors associated with treatment outcome were analyzed. Results There were 49 (10.65%) HIV among 460 TB patients with a median (IQR) age of 44 (32–61) years old and 65.2% were males. Disseminated TB and extrapulmonary TB were higher in HIV coinfected group (P < 0.001). All pulmonary TB patients’ lower lobe involvement was higher in HIV coinfected group (62.50 vs. 36.00, P = 0.001). In HIV coinfected group median CD4 was 134 cell/mm3 (IQR 19–294), 66.67% were diagnosed HIV infection after TB diagnosis, the median time from TB diagnosed to antiretroviral was 29 days (IQR 21–48). The overall treatment success rate was 93.04%; the treatment success rate was similar in HIV coinfected TB patients (89.80%) and non- HIV-infected patients (93.43%) (P = 0.66).Adverse drug reactions were higher in HIV coinfected group (44.89% vs 12.41%) (P < 0.001). By multiple stepwise logistic regression, factors associated with anti-TB drug adverse reactions were having HIV infection (OR 7.99; 95% CI 3.73–17.10, P < 0.001), Age >60 years (OR 2.64; 95% CI 1.43–4.87, P = 0.002) and female sex (OR 1.97; 95% CI 1.11–3.52, P = 0.02). Conclusion There is a high TB treatment success rate among patients who have treated for TB, but adverse drug events in HIV co-infected TB patients is higher than that observed in non-HIV-infected patients.
