Effect of 4 Weeks of Cervical Deep Muscle Flexion Exercise on Headache and Sleep Disorder in Patients with Tension Headache and Forward Head Posture

The purpose of this study was to investigate the effect of flexion exercise of the deep cervical muscles on headache and sleep disorders in patients with tension headaches and forward head posture. A total of 32 patients with tension headaches and forward head posture were randomly assigned to two groups: an experimental group (n = 16) and a control group (n = 16). The experimental group performed cervical deep muscle flexion exercises for 4 weeks, whereas the control group performed stretching exercises for the same period. The Henry Ford Hospital Headache Disability Inventory (HDI) was used for headache assessment, and the Korean version of the Pittsburgh Sleep Quality Index (PSQI-K) was used for sleep disorder assessment. The experimental group showed a significant reduction in both HDI and PSQI-K score after 4 weeks of intervention (p < 0.001), while no significant difference was found in the control group (p > 0.05). On comparing the experimental and control groups, we found a significant difference in changes in the HDI and PSQI-K between the groups (p < 0.05). The results indicate that flexion exercise of the deep cervical muscles in patients with tension headache and forward head posture will improve the quality of life and activities of daily life by mitigating headaches and sleep disorders.

Improvement in Brazilian Butt Lift (BBL) Safety With the Current Recommendations from ASERF, ASAPS, and ISAPS

Background In 2017, the ASERF Gluteal Fat Grafting Task Force reported gluteal fat grafting to be a high-risk procedure and recommended specific surgical techniques to decrease the risk of pulmonary fat embolism (PFE). Objectives The aim of this study was to determine whether ASAPS and ISAPS members were aware of the 2017 recommendations, what their current surgical techniques were, whether they had changed their techniques based on the 2017 recommendations, and whether the incidence of PFEs had changed since the recommendations were published. Methods An anonymous web-based survey was conducted among members of ASAPS and ISAPS. It included the questions from the 2017 survey, as well as questions about awareness of the Task Force recommendations and subsequent change in surgical techniques. Results In the 2 years following the publication of the recommendations, the incidence of any PFE was 1 in 2492 compared with 1 in 1030 reported in 2017 (P = 0.02). Trends indicated a decreased mortality rate from 1 in 3448 in 2017 to 1 in 14,952 in 2019. Ninety-four percent of respondents were aware of the recommendations. Only 0.8% of surgeons in the current survey reported injecting in deep muscle, compared with 13.1% in 2017 (P &lt; 0.01). Compared with 4.1% in 2017, 29.8% of respondents in our survey reported that they only injected with cannulas ≥4.1 mm (P &lt; 0.01). Only 4% of respondents reported angling the cannula down in the current survey, compared with 27.2% in 2017 (P &lt; 0.01). Conclusions It appears that members were aware of the 2017 recommendations. There was a significant decrease in recent PFE and trends showed a change to safer techniques and an improvement in safety of the procedure.
