Insertion of middle ear ventilation tubes (MEVT), tympanostomy tubes or grommets is one of the most common paediatric surgical procedures performed by ENT surgeons worldwide. Outcomes may be complicated by postoperative otorrhoea and ventilation tube blockage.

To identify risk factors associated with early postoperative complications of MEVT insertion.

In a case-control study, set in a tertiary hospital in Melbourne, Australia, 590 paediatric patients undergoing grommet insertion between February 2017 and February 2018, 311 patients (205 males & 106 females; median age of 3.86 years) met the inclusion criteria and had identical middle ear status bilaterally.

Tympanostomy tube insertion and postoperative topical otic antibiotic drops.

Patient age, gender, weight/BMI percentile, intraoperative middle ear status, number of previous grommets, type of surgery, season of surgery, diagnosis and time to first medical review were examined. The duration of topical otic antibiotic drops used and tube patenage less then 3 years were associated with developing otorrhoea. Topical antibiotic exposure was inversely associated with developing postoperative otorrhoea. 6.4% of patients had grommet blockage. Presence of serous middle ear effusion intraoperatively was a statistically significant indicator for developing grommet blockage.
To describe the specific retrofacial surgical approach for application of Vibrant Soundbridge (VSB) to the round window (RW) in patients with congenital ear malformation.

Four patients with congenital ear malformation were implanted with VSB unilaterally through a retrofacial approach in present study. During the operation, the round window niche was identified through a retrofacial pathway and the floating mass transducer (FMT) was attached to the RW inferiorly.

Satisfied outcomes were confirmed after surgery. No intraoperative or postoperative surgical complications were observed in all patients.

When the facial nerve was aberrant or it was unable to access the RW through the classic facial recess pathway during the round window vibroplasty, the retrofacial approach could be a valid and feasible alternative approach.

this study aimed to evaluate the efficacy of local application of Carnoy's solution following the surgical excision of recurrent PGCG.

40 patients who sought treatment for recurrent PGCG were included in this study. According to the type of treatment the patients were classified randomly into two equal groups. The lesions in all patients were excised down to the alveolar bone followed by aggressive curettage. Then only in group II, Carnoy's solution was applied for 5 min. Clinical follow-up was done for 1 year to evaluate the tissue healing.

patients were 23 females and 17 males, with an average of 35.9years. Recurrent PGCGs occurred most commonly in fifth decade of life (25 %). Maxilla (57.5 %) was involved more than the mandible. The lesions were found posteriorly in 27cases and anteriorly in 13cases. The average size of the lesions was 2.9 cm. Histologically, foci of calcifications occurred in 12cases. Recurrence occurred in 5 cases 4 in group I and 1 in group II. Bone healing was appropriate in all patients without sequestration.

the use of Carnoy's solution following surgical removal of recurrent PGCG decreases their recurrence rates. The technique is safe, and conservative with low tissue morbidity.

To investigate the expression of pigment epithelium-derived factor (PEDF) in ocular surface in dry eye disease (DED) and its anti-inflammatory roles and mechanisms, clinically and by experiments in vivo and in vitro.

A cross-sectional study was conducted to detect the expression of PEDF in tears of dry eye patients by enzyme-linked immunosorbent assay (ELISA). https://www.selleckchem.com/products/at-406.html Using dry eye mouse model and human corneal epithelial cells (hCECs) stimulated by hyperosmolarity or inflammatory cytokines, expression of PEDF in corneal epithelial cells, stroma and conjunctiva was quantified by real-time polymerase chain reaction, ELISA and Western blot. Next, either dry eye mice or hyperosmotic hCECs were treated with recombinant PEDF or neutralizing antibodies, and the expressions of inflammatory cytokines and immune cells were detected. Finally, Western blot was performed on MAPK and NF-κB to investigate the signaling pathways by which PEDF played its roles.

Concentrations of PEDF were increased in tears of dry eye patients. Increased PEDF was observed in corneal epithelial cells (CECs) rather than corneal stroma or conjunctiva in dry eye mice. Furthermore, hCECs exposed to hyperosmolarity showed upregulation of PEDF. In vivo and in vitro studies showed that PEDF suppressed the expression of inflammatory cytokines including IL-1β, IL-6, TNF-α and IL-17A, as well as the percentage of Th17cells in DED. Further investigation showed that PEDF inhibited the phosphorylation of MAPK p38 and JNK in hyperosmotic hCECs.

CECs derived PEDF is increased in DED. PEDF plays anti-inflammatory and immunoregulatory roles in the pathogenesis of DED.

This systematic review (SR) assessed the efficacy, safety and cost-effectiveness of cell-based therapy to manage limbal stem cell deficiency (LSCD), a sight-threatening orphan condition most frequently associated with severe chemical or thermal burns. LSCD has historically been treated by transplanting limbal tissue. In 1997, a new treatment, cultured limbal epithelial autografts, was described for unilateral LSCD. In cases of bilateral disease cultured autologous oral mucosa stem cells have been used. The relative efficacy of different cultured tissue procedures is unknown.

A protocol was registered with PROSPERO (CRD42017081117). Searches were conducted in 14 databases and 6 conference websites. Two reviewers independently selected studies, conducted data extraction and assessed risk of bias. One reviewer extracted individual patient data (IPD); a second checked extracted data. Data were assessed to determine the feasibility of statistical analysis, with Bayesian synthesis used to estimate improvement achieved by different treatments.
