Ocular cicatricial pemphigoid (OCP) is a chronic bilateral, blinding, cicatrizing form of conjunctivitis with relapsing and remitting periods. It has strong evidence for an immune type II hypersensitivity that leads to subconjunctival fibrosis and extensive systemic bullae formation. To the best knowledge of the authors, this is the first reported case of direct immunofluorescence (DIF) assay-proven OCP in an elderly Filipino man.

A 68-year-old male presented with bilateral corneal conjunctivalization, symblepharon, ectropion, conjunctival hyperemia testing positive with conjunctival biopsy for basement membrane antibodies with DIF for the left eye, while turning out negative for the right eye. He was managed as a case of OCP, both eyes, and was given topical steroids and antibiotics. Oral Dapsone was started by Dermatology and Rheumatology Services.

OCP is a rare autoimmune and blinding disease. Early diagnosis and prompt treatment are vital as ocular complications permanently affect the quality of life of patients as seen in our patient. DIF assay remains the gold-standard for diagnosis. Systemic immunosuppression is the mainstay of treatment. Adjunctive supportive topical medication may be given to alleviate ocular discomfort. A multidisciplinary approach is essential to provide holistic care to each patient.

A rectal polyp is found during a routine colonoscopy of a 34-year-old male. He has no known significant family history of inherited disorder. Endoscopic findings reveal a 5-mm JNET 2A polyp in the rectum which is removed via forceps polypectomy. The microscopic examination shows a polypoid colonic mucosa with fairly circumscribed proliferation of low-grade spindle cells in the lamina propria, separating the crypts. The individual spindle cells are uniform in size with abundant eosinophilic cytoplasm. No mitotic figures, nuclear atypia, pleomorphism and necrosis are noted. Likewise, the crypts do not exhibit serrated architecture.

As effective modalities to improve the stability of peri-implant hard and soft tissue, keratinized mucosa augmentation has increasingly been applied in daily practice. Nonetheless, there is still lack of in-depth comprehensive discussion regarding the surgical risk factors, the decision-making strategy and the surgical principle. In this article, three routine procedures of peri-implant keratinized mucosa augmentation were introduced. The surgical principles were deeply discussed and summarized with five key principles. Based on the risk assessment of local factors, the effects of which were analyzed on keratinized mucosa augmentation comprehensively, the authors proposed a decision-making protocol for selection of surgical procedures in the end, intending to provide guidelines for clinical application.

Objective: To summarize the follow-up outcomes of frontal drill out procedures (draf Ⅱb, extended draf Ⅱb and draf Ⅲ) using mucosal flaps, and discuss the surgical indications of different mucosal flaps and their potential benefits to the opening of the frontal neo-ostium. Methods: A total of 48 patients with chronic rhinosinusitis or frontal mucoceles treated by draf Ⅱb, extended draf Ⅱb and draf Ⅲ between 2013 and 2019 in Beijing TongRen Hospital were enrolled in this study. Twenty-four patients who were treated with mucosal flaps were considered as mucosal flap group (including 19 males and 5 females, aging from 19 to 71 years), and the other 24 patients who didn't have neo-ostium reconstruction were considered as control group (including 18 males and 6 females, aging from 21 to 63 years). The frontal neo-ostium crosssectional area was measured with osiriX^® 7 days and 1 year postoperatively. Lund-Kennedy score (LKS) was also completed to analyze the difference of therapeutic effect between mucosal flap group and control group. SPSS 23.0 software was used for statistical analysis. Results: The postoperative follow-up time was 18 to 102 months. The postoperative epithelialization time in the mucosal flap group and the control group was (2.5±0.9) months and (3.0±0.7) months (Mean±SD), respectively, with statistically significant (t=1.97, P=0.024). At the end of follow-up, 23 cases (95.8%) had well opened frontal neo-ostium, 1 case (4.2%) was re-stenosed, and there was no revision surgery in the mucosal flap group. In the control group, 16 cases (66.7%) had well opened frontal neo-ostium, 8 cases (33.3%) were re-stenosed, 4 cases (16.7%) had revision surgery. The mucosal flap group had much fewer stenosis cases than control group (χ²=4.92, P=0.027). The neo-ostium area in the mucosal flap group and the control group was reduced by (0.87±0.58) cm² and (1.54±1.15) cm² 1 year after operation respectively, with statistically significant (t=1.72, P=0.046). There was no case of frontal sinus atresia and no surgical complication in both groups. The two-factor repeated measurement analysis of variance after surgery showed that the average LKS of the mucosal flap group was 0.78 points lower than that of the control group. In other words, the influence of grafting technique on LKS was statistically significant (F=5.33, P=0.035). Conclusions: The application of mucosal flaps to cover the denuded bone during frontal drill out procedures can prohibit mucosal scar and new bone formation, and significantly reduce the stenosis rate of frontal neo-ostium.

Lactic acid bacteria (LAB) are generally recognized as safe food-grade microorganisms and are widely used in food production, preservation, and as probiotics to promote human health. Given the need to develop effective drug delivery strategies, LAB have become attractive live vehicles for the oral, intranasal and vaginal delivery of therapeutic molecules. Being live and safe organisms, LAB are able to directly produce and deliver target proteins for therapeutic purpose, which remarkably reduces the cost for drug production. To date, LAB have been used to deliver a variety of functional proteins to mucosal tissues for the treatment of various diseases. This review summarized the development and application of LAB as mucosal delivery vectors in the last 20 years to provide references for future clinical research.
