Purpose: To compare nylon monofilament suture with polytetrafluoroethylene sheet for frontalis suspension surgery to treat eyes with congenital ptosis.
Design: Retrospective, nonrandomized, comparative, interventional case series.
Methods: We reviewed the medical records of 49 patients who had undergone 79 eyelid frontalis suspension surgeries to treat congenital ptosis. All of the patients were younger than 16 years and had congenital ptosis with poor levator muscle function. They were treated with frontalis suspension surgery with either a nylon suture or a polytetrafluoroethylene sheet and were followed up for at least 1 year. A single rhomboid loop sling was used for the nylon suture surgery. For the polytetrafluoroethylene sheet, an incision was made in the eyelid crease, and one end of the sheet was fixed to the tarsus and the other was fixed to the frontalis muscle. The main outcome measures were postoperative recurrences and complications.
Results: We evaluated 37 eyelids of 25 patients after nylon suture surgery and 42 eyelids of 31 patients after polytetrafluoroethylene sheet surgery. Among these, 9 eyelids of 7 patients were included in both groups. The median postoperative follow-up period was 32 months in both groups. The recurrence rates were 62.2% for the nylon suture group and 0% for the polytetrafluoroethylene sheet group (P < .001). The postoperative complication rates were 0% for the nylon suture group and 7.1% for the polytetrafluoroethylene sheet group (P > .05).
Conclusions: Frontalis suspension using a polytetrafluoroethylene sheet with direct tarsus and frontalis muscle fixation is a reasonable technique with low rates of recurrences and complications.

Background: Various complications of permanent pacemaker implantation have been reported. However, late pacemaker lead-related myocardial perforation rarely occurs. Conservative treatment is generally selected, if possible, but open heart surgery or catheter lead removal should be considered in symptomatic patients.

With the increasing focus on triboelectric-based sensors, research on synthesizing dielectric layers from specific substances is gradually emerging. Despite numerous negatively-charged triboelectric materials, there is a scarcity of synthesizable positively-charged materials, creating a research gap. This study demonstrates the molecular design of a conjugated, mesoporous, self-assembled sheet via bottom-up synthesis.

Human physical activity monitoring plays a crucial role in promoting personalized health management. In this work, inspired by an ancient Chinese belt, a belt-type wearable sensor (BWS) based on a triboelectric nanogenerator (TENG) is presented to monitor daily movements and collect the body motion mechanical energy. The developed BWS consists of a soft silicone sheet and systematically connected sensing units made from triboelectric polymer materials including polytetrafluoroethylene (PTFE) and polyamide (PA).
