Purpose: To give the long-term success rates of punctal dilatation with insertion of perforated punctal plugs (PPP) for the management of acquired punctal stenosis.
Methods: A series of 44 eyes of 26 patients who underwent PPP implantation for the management of acquired punctal stenosis were retrospectively evaluated in terms of the severity of acquired punctal stenosis, associated eyelid disorders, implantation technique of PPP, and long-term success rate of PPP for the treatment of epiphora. In all patients, punctal dilation was performed prior to the insertion of plugs. Patients demonstrating moderate or severe horizontal eyelid laxity underwent a lateral tarsal strip procedure before PPP implantation. Complete stenosis of the punctum was treated with the radiofrequency unit before PPP implantation. The plugs were extracted at 2 months in every patient.
Results: The mean age of the patients was 63.6 +/- 10.5 years. The median interval between the onset of epiphora and PPP implantation was 15 months. There were 14 complete stenoses, 29 partial punctal stenoses, and 1 squamous papilloma involving the inferior punctum causing epiphora. Associated eyelid laxity was detected in 14 of 44 eyes (31.8%), and 8 eyes underwent a lateral tarsal strip procedure before PPP implantation. The mean follow-up time was 19.0 +/- 13.4 months. Success was achieved in 37 of 44 eyes (84.1%), with relief of epiphora. Of the 7 eyes with continued epiphora, 3 eyes demonstrated recurrent punctal stenosis and 4 eyes demonstrated mild horizontal eyelid laxity.
Conclusions: The long-term success rate of PPP implantation for the treatment of acquired punctal stenosis is satisfactory. Associated eyelid pathologies should be evaluated for their contribution to epiphora and be treated before PPP implantation.

Introduction: Platelet-rich fibrin (PRF) is being increasingly utilized in surgical procedures due to various improvements in clinical outcomes. More recently, a heating process to denature albumin in the platelet poor plasma (PPP) layer has been shown to extend the resorption time of PRF from a typical 2-week period to 4-6 months. Because of its > 4 month resorption properties, extended PRF (e-PRF) membranes have been used in dentistry as an alternative to collagen membranes in alveolar ridge preservations, ridge augmentations, soft tissue grafting, and as a barrier membrane in lateral sinus grafting procedures.

Article Synopsis
- The combination of pancreatitis, panniculitis, and polyarthritis (PPP) is a rare syndrome linked with pancreatitis or pancreatic cancers, highlighted by a case of a 50-year-old man who experienced worsening polyarthritis and nodules on his legs.
- Lab tests confirmed pancreatitis, and a dermatological assessment established panniculitis, leading to the diagnosis of PPP.
- Initial treatments with glucocorticoids and NSAIDs were ineffective, but after performing endoscopic retrograde cholangiopancreatography (ERCP) to remove blockages in the pancreatic duct, the patient's symptoms improved significantly, emphasizing the need for multidisciplinary awareness and management of this condition.

Psammocarcinoma is an uncommon subtype of low-grade serous carcinoma. It is characterized by the presence of extensive psammoma bodies and can have either an ovarian or peritoneal origin. To our knowledge fewer than 30 cases of primary peritoneal psammocarcinoma (PPP) have been reported in the English literature.

Purpose: Establishing the diagnosis of loosening in total or unicondylar knee arthroplasty remains a challenge with different clinical and radiological signs evaluated in study designs with high risk of bias, where few or incomplete criteria are formulated for establishing the diagnosis of implant loosening. This study aimed at evaluating the variability between different clinical and radiological criteria and establish a consensus regarding clinical and radiological criteria for the diagnosis of knee arthroplasty loosening.
Methods: Highly specialized knee surgeons focusing on revision arthroplasty were invited to take part in an international panel for a Delphi consensus study.

Purpose: To explore the therapeutic effect of stromal cell derived factor-1α(SDF-1α) combined with platelet-poor plasma(PPP) on permanent tooth avulsion injury.
Methods: One hundred and forty-four patients with permanent tooth avulsion injuries admitted to Hengshui People's Hospital from March 2020 to March 2022, with a total of 152 affected teeth were included. They were randomly divided into experimental group of 72 cases(76 teeth) and control group of 72 cases(76 teeth).
