Purpose: The purpose of this study was to assess the results of bleb needling in glaucomatous patients with late failed filtering blebs.
Materials And Methods: A retrospective case series of 27 eyes of 27 patients was considered. All patients underwent needle bleb revision with adjuvant mitomycin-C performed at the slit lamp, during an office visit. Complete success was defined as postneedling intraocular pressure (IOP) ≤ 21 mmHg without any antiglaucoma medications and qualified success was IOP ≤ 21 mmHg with topical antiglaucoma medications.
Results: There were 12 eyes with encapsulated blebs and 15 eyes with flat blebs. The mean interval between index filtering surgery and bleb revision was 32.74 ± 15.36 months. Mean IOP was 25.07 ± 4.80 mmHg before surgery and 19.66 ± 4.97 mmHg at last postoperative follow-up. The mean follow-up was 20.31 ± 15.63 months. Complete and qualified successes were 7.4% and 51.9%, respectively. Cumulative rates of success at 1, 2, 3, and 4 years were 76%, 65%, 49%, and 37%, respectively. The mean number of antiglaucoma medications was reduced from 3.15 ± 0.36 preoperatively to 2.33 ± 1.21 postoperatively (P<0.001).
Conclusion: Slit-lamp needle revision in office is a simple and effective method for treating late encapsulated or flat filtering blebs without significant complications even for late bleb failure.

How social frailty is operationalized matters: Relationships with health and wellbeing in late adulthood.
Int Psychogeriatr
January 2025
School of Psychology, The University of Queensland, Brisbane, Australia.
Objectives: There are currently major inconsistencies in the methodological approaches used to index social frailty. The present study aimed to better understand which of these approaches may be most valuable in predicting older adult's physical health and psychological wellbeing.
Design: One hundred and thirty-three participants aged 60-90 years completed five measures commonly used to index social frailty, along with five measures of physical health, and psychological wellbeing.
Intraprosthetic Dislocation Following Dual Mobility Total Hip Arthroplasty: A Retrieval Analysis Study.
Arthroplast Today
February 2025
Department of Orthopaedic Surgery, Fiona Stanley Fremantle Hospitals Group, Murdoch, Western Australia, Australia.
Background: Dual mobility (DM) implants in total hip arthroplasty provide excellent range of motion with low dislocation rates. A complication of this design is intraprosthetic dislocation (IPD), where the polyethylene (PE) liner dissociates from the femoral head. In older designs, IPD occurred due to a small head size and late PE wear with head-capture-mechanism failure.

Background: Intrauterine growth restriction (IUGR) is a severe condition in which the fetus fails to reach its genetically predetermined growth potential, impairing prenatal development and predisposing individuals to postnatal consequences that may persist into adulthood. Although fetal mechanisms such as the brain-sparing effect have been proposed to protect the brain against IUGR-related deficits, the extent of this protection remains unclear.
Objective: To conduct a systematic review that demonstrates prenatal morphofunctional abnormalities in the brain of individuals with IUGR.

Department of Surgery, King Khalid University Hospital, Riyadh, Saudi Arabia.
Background: Obesity is an alarmingly increasing global public health issue. Laparoscopic sleeve gastrectomy (LSG) is the most common bariatric surgery owing to its simplicity, effectiveness, and low complication rates. The complications can be classified as early or late, with fistula formation being one of the most severe complications.
