OBJECTIVE
Attic retraction pockets, classified by degree of invasion and erosion, are reconstructed here as outlined by attic retraction pocket grade.
METHOD
Attic retraction pocket grade, surgical management, subsequent conditions of tympanic membrane and middle ear, and improvement of air-bone gap pure tone average were recorded.
RESULTS
Our management strategy, based on attic retraction pocket grade, was applied to 200 ears: 44 grade I ears had non-surgical management and 156 grade II-V ears had surgical management. All 200 ears were followed up for 36-240 months, showing only 1 attic retraction pocket reformation and 1 adhesive otitis media (complication rate of 1 per cent), and improved air-bone gaps ( < 0.05). An earlier series of 50 grade IV attic retraction pockets used atticotomy with epitympanic reconstruction. These showed attic retraction pocket recurrence or cholesteatoma onset in 34 ears (68 per cent). When these ears were revised per protocol, there was no evidence of cholesteatoma thereafter.
CONCLUSION
Reconstruction of the ossicles and scutal defect according to attic retraction pocket grade shows long-term stability of the tympanic membrane, middle ear and hearing.

Review
Infective endocarditis (IE) is a disease of the endocardium, which leads to the appearance of vegetation on the valves, cardiac structures, or, potentially, vascular endothelium of the heart. The risk of IE can be increased more than 140 times by congenital heart disease (50-59% of all IE), particularly if cyanotic. An increase in mortality may result from IE in patients with a complex cardiac pathology or patients with an implanted prosthetic material, most frequently conduits in a pulmonary position. Cardiac implantable electronic devices (CIED) infective endocarditis is a life-threatening complication representing 10% of all cases of endocarditis. Common signs of presentation are often fever and chills; redness and swelling at the pocket of the pacemaker, including the erosion and exteriorization of the device; and life-threatening sepsis. The use of intracardiac echocardiography for the diagnosis of IE is an innovative method. This may be needed, especially in older children undergoing complex cardiac surgery, when transthoracic echocardiography (TTE) and transesophageal echocardiography (TOE) failed to provide a reliable diagnosis. The 2018 European Heart Rhythm Association (EHRA) experts' consensus statement on transvenous lead extraction recommends complete device removal and antimicrobial therapy for any device-related infection, including CIED-IE. The most detected microorganism was Staphylococcus Aureus. In addition, cardiac surgery and interventional cardiology associated with the placement of prostheses or conduits may increase the risk of IE up to 1.6% for Melody valve implantation. Our manuscript presents a comprehensive review of infective endocarditis associated with cardiac devices and prostheses in the pediatric population, including recent advances in diagnosis and management.

Oral health plays a significant role in the quality of life and overall well-being of the aging population. However, age-related changes in oral health are not well understood due to challenges with current animal models. In this study, we analyzed the oral health and microbiota of a short-lived non-human primate (i.e., marmoset), as a step towards establishing a surrogate for studying the changes that occur in oral health during human aging. We investigated the oral health of marmosets using cadaveric tissues in three different cohorts: young (aged ≤6 years), middle-aged, and older (>10 years) and assessed the gingival bacterial community using analyses of the V3-V4 variable region of 16S rRNA gene. The oldest cohort had a significantly higher number of dental caries, increased dental attrition/erosion, and deeper periodontal pocket depth scores. Oral microbiome analyses showed that older marmosets had a significantly greater abundance of Escherichia-Shigella and Propionibacterium, and a lower abundance of Agrobacterium/Rhizobium at the genus level. Alpha diversity of the microbiome between the three groups showed no significant differences; however, principal coordinate analysis and non-metric multidimensional scaling analysis revealed that samples from middle-aged and older marmosets were more closely clustered than the youngest cohort. In addition, linear discriminant analysis effect size (LEFSe) identified a higher abundance of Esherichia-Shigella as a potential pathogenic biomarker in older animals. Our findings confirm that changes in the oral microbiome are associated with a decline in oral health in aging marmosets. The current study suggests that the marmoset model recapitulates some of the changes in oral health associated with human aging and may provide opportunities for developing new preventive strategies or interventions which target these disease conditions.

Opuntia monacantha: Validation of the anti-inflammatory and anti-arthritic activity of its polyphenolic rich extract in silico and in vivo via assessment of pro- and anti-inflammatory cytokines.
ETHNOPHARMACOLOGICAL RELEVANCE
Opuntia monacantha belongs to the cactus family Cactaceae and is also known by cochineal prickly pear, Barbary fig or drooping prickly pear. It was traditionally used to treat pain and inflammation. O. monacantha cladodes showed pharmacological effects such as antioxidant potential owing to the presence of certain polysaccharides, flavonoids, and phenols.
AIM OF THE STUDY
This research aimed to evaluate the anti-inflammatory as well as the anti-arthritic potential of ethanol extract of Opuntia monacantha (E-OM).
MATERIALS AND METHODS
In vivo edema in rat paw was triggered by carrageenan and used to evaluate anti-inflammatory activity, while induction of arthritis by Complete Freund's Adjuvant (CFA) rat model was done to measure anti-arthritic potential. In silico studies of the previously High performance liquid chromatography (HPLC) characterized metabolites of ethanol extract was performed by using Discovery Studio 4.5 (Accelrys Inc., San Diego, CA, USA) within active pocket of glutaminase 1 (GLS1) (PDB code: 3VP1; 2.30 Å).
RESULTS
EOM, particularly at 750 mg/kg, caused a reduction in the paw edema significantly and decreased arthritic score by 80.58% compared to the diseased group. It revealed significant results when histopathology of ankle joint was examined at 28th day as it reduced inflammation by 18.06%, bone erosion by 15.50%, and pannus formation by 24.65% with respect to the diseased group. It restored the altered blood parameters by 7.56%, 18.47%, and 3.37% for hemoglobin (Hb), white blood count (WBC), and platelets, respectively. It also reduced rheumatoid factor RF by 13.70% with concomitant amelioration in catalase (CAT) and superoxide dismutase (SOD) levels by 19%, and 34.16%, respectively, in comparison to the diseased group. It notably decreased mRNA expression levels of COX-2, IL-6, TNF-α, IL-1, NF-κβ and augmented the levels of IL-4 and IL-10 in real time PCR with respect to the diseased group and piroxicam. HPLC analysis previously performed showed that phenolic acids and flavonoids are present in E-OM. Molecular docking studies displayed pronounced inhibitory potential of these compounds towards glutaminase 1 (GLS1), approaching and even exceeding piroxicam.
CONCLUSIONS
Thus, Opuntia monacantha could be a promising agent to manage inflammation and arthritis and could be incorporated into pharmaceuticals.

OBJECTIVE
Inflammatory pathogenesis is common to periodontitis and oral lichen planus. This study was conducted to assess and compare the periodontal status of patients with and without oral lichen planus.
METHOD AND MATERIALS
108 patients comprising 54 with oral lichen planus and 54 age-matched systemically healthy participants without oral lichen planus were selected. Periodontal parameters, ie Plaque Index, Gingival Index, bleeding on probing, probing pocket depth, clinical attachment level, and periodontal phenotype were measured.
RESULTS
On comparing the test and control groups, statistically significant differences were observed in respect to Plaque Index (P = .00), Gingival Index (P = .00), and bleeding on probing (P = .00). A higher proportion of sites with deeper pockets was observed in the test group (P = .00). On comparison of various oral lichen planus subtypes, significant difference was observed in respect to Gingival Index (P = .00) and bleeding on probing (P = .00). A higher proportion of sites with deeper pockets (P = .01) and greater CAL (P = .00) was observed in the erosive/atrophic subgroup compared to the reticular group. However, the differences between the reticular (a less severe form of oral lichen planus) and control group in terms of Gingival Index (P = .94), Plaque Index (P = .05), bleeding on probing (P = .17), probing pocket depth (P = .56), and clinical attachment level (P = .23) were not statistically significant. Statistically significant differences were observed in terms of Gingival Index (P = .01) and bleeding on probing (P = .00) between thin and thick periodontal phenotypes in the oral lichen planus group. Statistically significant positive correlations in periodontal parameters with increased gingival involvement and severity were observed using Spearman rank correlation coefficient.
CONCLUSION
Significantly greater periodontal inflammation in the test group means there is a risk of greater attachment loss in future. Thus, increased attention towards periodontal health in these patients might reduce the rate of disease progression.

PURPOSE
We will describe a minimally invasive technique for the repair of iridodialysis, without conjunctival dissections, using intrasceral fixation of a 6-0 polypropylene suture with a flanged tip.
METHODS
A flange was created at the end of the suture with thermoplasticity. An ab interno passing of the needle attached to the suture was performed through the peripheral part of the iris and was further passed out from the eye 1.5 mm to 2 mm behind the limbus. Intrascleral fixation of the exterior suture was performed with the aid of the attached needle. After adjusting the tension of the iris relocation, the externalized end of the suture was cut flush to the sclera with scissors. For a wide dialysis, the same manipulations were repeated until the repair was completed.
RESULTS
The technique was used in three eyes of three patients. No visual impairments of monocular diplopia and glare were observed after surgery. Postoperatively, the irises remained well positioned, with no suture erosion, suture loosening, hypotony, scleral atrophy, or chronic inflammation being observed within the follow-up period. Mild postoperative hyphema was observed in one eye of blunt trauma.
CONCLUSION
The present technique provides minimal surgical invasion for the repair of iridodialysis without creations of scleral flap/groove/pocket and conjunctival dissection.

Retina (Philadelphia, Pa.) Dec 2023To present the flattened flanged polypropylene suture technique developed to obtain round and stable pupils in patients with iridodialysis.
PURPOSE
To present the flattened flanged polypropylene suture technique developed to obtain round and stable pupils in patients with iridodialysis.
METHODS
After performing a fornix-based conjunctival peritomy, a flange was created at the tip of a 6.0 polypropylene suture by cautery. In the quadrant of iridodialysis, an ultrathin 30-gauge needle was inserted into the sclera at a distance of 2 mm from the limbus and advanced 1.5 mm intrasclerally, parallel to the limbus. The needle was directed radially into the eye and easily passed through the edge of the peripheral iris. The polypropylene suture was pushed into the lumen of the needle with the help of forceps. After the needle was externalized, the tip of the suture was flanged by cautery, and the flange was immediately flattened using a needle holder.
RESULTS
Six eyes of six patients with iridodialysis were enrolled in this study. Postoperatively, the irises remained well positioned and the pupils became round in all eyes. None of the patients developed suture erosion, suture loosening or rupture, hyphema, hypotony, chronic iridocyclitis, and angle closure.
CONCLUSION
The present technique provides a minimally invasive surgery and robust iris fixation without the need to create a scleral flap, groove, or pocket.

BACKGROUND
Retraction pocket (RP) of the tympanic membrane (TM) is a common pathology in children that can cause ossicular chain erosion, cholesteatoma formation, and potentially life-threatening complications of cholesteatoma. This study assessed the functional and anatomical results of cartilage grafting in children with severe RP of the TM.
METHODS
This was a retrospective review of 212 children from a tertiary referral center.
RESULTS
We identified significant differences in hearing results, indication criteria, and location of TM fixation between stages II and III of RP (according to Charachon). We observed a significantly higher incidence of RP in boys than in girls.
CONCLUSIONS
Cartilage tympanoplasty for retraction pocket of the tympanic membrane in children is a safe procedure with good anatomical and hearing results.

Epidermal growth factor receptor inhibitors (EGFRIs) are widely used to treat various types of malignancies. One of the common adverse reactions is cutaneous toxicity, mostly presenting as acneiform eruptions, paronychia and xerosis. Erosive pustular dermatosis of the scalp (EPDS) is a rare cutaneous adverse reaction that develops during treatment with EGFRIs. The pathogenesis of EGFRI-induced EPDS is poorly understood. Here we present three cases of EPDS induced by EGFRIs. The proteins LTA4H (leukotriene A-4 hydrolase), METAP1 (methionine aminopeptidase 1), BID (BH3-interacting domain death agonist), SMAD1 (mothers against decapentaplegic homologue), PRKRA (interferon-inducible double-stranded RNA-dependent protein kinase activator A), YES1 (tyrosine-protein kinase Yes) and EGFL7 (epidermal growth factor-like protein 7) were significantly upregulated in EGFRI-stimulated peripheral blood mononuclear cell cultures, and validated in the lesions. All of the proteins colocalized with CD4+ and CD8+ T-cell expression. Next-generation-based human leucocyte antigen (HLA) typing showed all patients carried HLA-C*15:02, and modelling studies showed that afatinib and erlotinib bound well within the E/F binding pockets of HLA-C*15:02. Moreover, T cells were preferentially activated by EGFRIs in individuals carrying HLA-C*15:02. The case series revealed that EGFRI-induced EPDS may be mediated by drug-specific T cells.

Rheumatoid arthritis (RA) is an idiopathic and chronic autoimmune disease for which there are currently no effective treatments. Oxypeucedanin hydrate (OXH) is a natural coumarin known for its potent anti-inflammatory properties. However, further investigations are needed to determine its therapeutic efficacy in treating RA. In this study, we evaluate the anti-inflammatory activity of OXH by treating LPS-induced RAW264.7 macrophages. Our results show that OXH treatment reverses the changes in iNOS, COX-2, IL-1β, IL-6, and TNF-α levels. Additionally, OXH reduces ROS production. Further analysis reveals that OXH suppresses the activation of the NF-κB/MAPK pathway. CETSA results show that OXH competes with LPS for binding to the TLR4/MD2 complex. MST experiments demonstrate the specific affinity of OXH for the TLR4/MD2 complex, with a Kd value of 33.7 μM. Molecular docking analysis suggests that OXH binds to the pocket of the TLR4/MD2 complex and interacts with specific amino acids, such as GLY-343, LYS-388, and PHE-345. Molecular dynamics simulations further confirm this conclusion. Finally, we investigate the potential of OXH in treating RA using a collagen-induced arthritis (CIA) model in rats. OXH effectively ameliorates the symptoms of CIA, including improving body weight, reducing swelling and redness, increasing talus volume, and decreasing bone erosion. OXH also decreases the mRNA levels of pro-inflammatory factors in synovial tissue. Transcriptome enrichment analysis and western blot analysis confirm that OXH suppresses the NF-κB/MAPK pathway, which is consistent with our findings.
