Oral Leishmaniasis in HIV-Positive and HIV-Negative Patients: A Comparative Analysis with Two New Case Reports.

PURPOSE: This case report examines the clinical presentation, diagnosis, treatment, and outcomes of mucocutaneous leishmaniasis with primary oral involvement in HIV-positive and HIV-negative patients diagnosed in Brazil. METHODS: We discuss the clinical manifestations, diagnostic methods, and therapeutic strategies, highlighting the clinical and histopathologic diagnostic features and distinct progression patterns based on HIV status. Our findings are compared with patterns observed in other countries, emphasizing the differences between the Americas and Europe, Asia, and Africa. RESULTS: In the Americas, particularly in Brazil, mucocutaneous leishmaniasis often presents with localized oral lesions, even in the presence of systemic immunosuppression, whereas in the Europe, Asia, and Africa, oral involvement is typically associated with visceral leishmaniasis in immunocompromised patients. These differences were due to variations in the parasite species involved. CONCLUSION: This comparison underscores the importance of regional and immunological factors in diagnosing and managing this neglected infectious disease.

Dyspnea Due to Laryngeal Cicatricial Pemphigoid: A Case Report.

Cicatricial pemphigoid (CP) is a rare, chronic, vesiculobullous disease characteristically affecting the mucous membranes and healing with cicatrization. Laryngeal involvement is rare and leads to airway stenosis. We present a 74-year-old Caucasian woman with CP, affecting the oral cavity, esophagus, lower eyelids, and larynx. Regardless of regular treatment with hydrocortisone and azathioprine, she developed bilateral cicatrization of the aryepiglottic folds and ovoid stenosis of the laryngeal introitus, leading to dyspnea. To avoid tracheostomy, we were able to utilize infraglottic high-frequency jet ventilation under total intravenous anesthesia to perform a CO2 laser supraglottoplasty with sectioning of the aryepiglottic folds. Post-operatively, her dyspnea at rest resolved; there was no progression at the six- and 12-month follow-up, and she was satisfied with the result.

Clinical and demographic characteristics of mucous membrane pemphigoid in India: A retrospective analysis.

Background Mucous membrane pemphigoid (MMP) is a rare subepidermal autoimmune blistering disorder. The clinical and demographic parameters of this disease in Indian patients have not yet been elucidated in detail. Objective We aimed to study the clinical and demographic characteristics, disease course, and treatment aspects of MMP patients. Methods The data for this study were obtained by reviewing the case record forms of patients registered in the Autoimmune Bullous Disease (AIBD) Clinic of the Department of Dermatology, Venereology & Leprology, Postgraduate Institute of Medical Education and Research, Chandigarh, a tertiary care centre in India. The diagnosis of MMP was established on the basis of clinical and immune-histopathological features which are consistent with standard diagnostic criteria for the disease. Results A total of 52 patients with MMP registered in the AIBD clinic were included. The mean age at disease onset was 50 years and the average age at presentation was 56 years. Females outnumbered males in the study with a ratio of 1.36:1. The oral and ocular mucosae were the most commonly affected sites (82.6% and 63.4% respectively). Visual difficulty was reported by half the patients (26 of 52 patients). IgG, C3, and IgA deposits were detected on direct immunofluorescence (DIF) in 29, 21, and 11 patients, respectively. Serologic analysis was performed in only 7 of the patients and of these, just 1 exhibited a positive result on multivariant ELISA and epidermal pattern of binding on salt split skin indirect immunofluorescence. Most patients were treated with prednisolone (44 of 52). Steroid-sparing adjuvants were used in combination including cyclophosphamide, azathioprine, methotrexate, dapsone, and colchicine. Rituximab was administered in 7 patients with severe or refractory disease. Limitations This is a retrospective analysis of data available from a clinic registry. In patients with negative direct immunofluorescence on biopsy, the diagnosis was based on clinico-pathologic consensus. Conclusion MMP is not as uncommon in India as the paucity of reports suggest. Visual complications are frequent in Indian MMP patients. A high index of suspicion is required for early diagnosis and appropriate treatment to prevent ocular complications.

Quantitative Morphological Study of Larynx APUD-Cells in Asphyxial Type of Drowning in Fresh Water (Experimental Study).

An additional microscopic diagnostic sign has been identified for verification of asphyxial type of drowning. In white non-linear male rats (age 2 months) subjected to free drowning, significant hyperplasia of argyrophilic and morphofunctional activity of serotonin-containing APUD-cells of the laryngeal mucosa were revealed under conditions of acute anoxia in comparison with the intact control. These changes promote the development of laryngospasm, which prevents water penetration into the airways and lungs in asphyxial type of drowning. The presence of statistically significant hyperplasia of argyrophilic and morphofunctional activity of serotonin-containing APUD-cells of the laryngeal mucosa under conditions of acute anoxia can be used as an additional diagnostic criterion for asphyxial type of drowning in experimental studies.

Patient in Mayfield Head Pins Requiring Prone Bronchoscopy for Mucus Plug Obstruction: A Case Report.

Mucus plug obstruction is a common complication in prone patients associated with loss of ventilation and hemodynamic instability. This case presents a 62-year-old female with chronic bronchitis who underwent posterior cervical fusion for a type III dens fracture with extension into the pars articularis and pedicles. Glycopyrrolate was administered to assist with fiberoptic intubation. After successful intubation, bronchoscopy revealed copious endotracheal secretions requiring preoperative therapeutic removal. Despite extensive removal of thick endotracheal secretions preoperatively, obstructive mucus plugging developed intraoperatively with complete loss of end-tidal carbon dioxide (ETCO2) while the patient was in Mayfield head pins. With limited airway access, suctioning and prone flexible bronchoscopy were performed, successfully restoring ETCO2. This experience underscores the need for heightened awareness and preparedness for mucus plug obstruction in chronic bronchitis patients undergoing prone cervical spine surgeries.

Condition of oral tissues in children with congenital cleft lip and palate.

OBJECTIVE: Aim: To study the condition of oral tissues in children with congenital complete cleft lip, alveolar process, hard and soft palate. PATIENTS AND METHODS: Materials and Methods: From the examined 470 children National Specialized Children's Hospital "OKHMATDYT" (Kyiv, Ukraine) with congenital cleft lip and palate was analyzed: 302 patients aged 8-18 years were subject to in-depth analysis for clinical and radiological - 192 with unilateral and 110 with bilateral complete cleft lip, alveolar process, hard and soft palate. RESULTS: Results: The average value of primary adention in patients with unilateral and bilateral complete combined cleft is 69.53%, but in females this indicator is higher and in unilateral cleft 92.18% for female against 53.17% for male. In females with unilateral cleft retention - 40.62% and overcomplete - 10,93%. The same high indicators in bilateral cleft: retention - 36.58% and overcomplete - 12.19%. Retention and overcomplete have higher values for men - 44.93% and 23.19%, respectively. Chewing efficiency in females with bilateral cleft as a result of primary dentition is below 80%. Affected by caries - 90.73% in both groups. Inflammatory processes in the periodontal tissues are revealed (80,75%): chronic catarrhal gingivitis, chronic hypertrophic gingivitis, chronic generalized periodontitis. Manifestations of atopic and angular cheilitis in 39.09% and 23.63% with bilateral cleft lip and palate, glossitis in 29.09%. CONCLUSION: Conclusions: Patients with congenital complete cleft lip, alveolar process, hard and soft palate have high rates of adentia, retention, overcomplete dentition and a wide range of diseases of the oral cavity, which negatively affects surgical and orthodontic rehabilitation.

Reactivity against the BP180 ectodomain in patients with bullous pemphigoid, mucous membrane pemphigoid, multiple sclerosis and Parkinson disease.

The 16th non-collagenous domain (NC16A) of BP180 is the main antigenic target of autoantibodies in bullous pemphigoid (BP) and mucous membrane pemphigoid (MMP). Commercially available assays detect serum autoantibodies against NC16A in the majority of BP (80%-90%) and in approximately 50% of MMP patients. However, a standardized test system for detecting antibodies against other regions of BP180 is still lacking. Moreover, anti-BP180 autoantibodies have been found in neurological conditions such as multiple sclerosis and Parkinson disease. This study aimed at identifying primary epitopes recognized by BP autoantibodies on the BP180 ectodomain. Serum samples of 51 BP and 30 MMP patients both without anti-NC16A reactivity were included along with 44 multiple sclerosis and 75 Parkinson disease sera. Four overlapping His-tagged proteins covering the entire BP180 ectodomain (BP180(ec)1-4) were cloned, expressed, purified and tested for reactivity by immunoblot. IgG antibodies to BP180(ec)3 were detected in 98% of BP, 77% of MMP and 2% of normal human sera. Only weak reactivity was detected for neurological diseases against BP180(ec)1, BP180(ec)2 and BP180(ec)4, in 3%, 11% and 7% of tested multiple sclerosis sera, respectively. 8% of Parkinson disease sera reacted with BP180(ec)2 and 9% with BP180(ec)4. In conclusion, this study successfully identified epitopes recognized by BP autoantibodies outside the NC16A domain in pemphigoid diseases. These findings contribute to a better understanding of the immune response in BP and MMP with potential implications for a future diagnostic assay for NC16A-negative pemphigoid patients.

Pemphigus vulgaris and mucous membrane pemphigoid: A systematic review of clinical manifestations, diagnosis, and treatment.

Pemphigus vulgaris (PV) and mucous membrane pemphigoid (MMP) are mucocutaneous autoimmune diseases characterized by blistering lesions of mucous membranes and skin, with very similar clinical manifestations. This study aimed to systematically review the literature on the clinical and demographic profile, diagnostic methods, and treatment of patients with pemphigus vulgaris (PV) and mucous membrane pemphigoid (MMP). Studies describing cases of PV and MMP diagnosed by direct immunofluorescence that exhibited intraoral manifestations were included. Thirty-two articles were included, with 18 studies on PV and 15 on MMP, corresponding to 50 and 123 cases diagnosed as PV and MMP, respectively. Most patients with PV (64 %) and MMP (81.3 %) were women in the fifth and sixth decade of life, respectively. The mouth was the primary site of involvement both in PV (71.4 %) and in MMP (91 %). The cheek mucosa and gingiva were the most frequently affected intraoral sites in PV (30 %) and MMP (64.2 %), respectively. Direct immunofluorescence was positive for IgG in all cases of the two conditions. The treatment of choice was systemic corticosteroid therapy for patients with PV (50 %) and topical treatment for patients with MMP (53.7 %). Differences in intraoral site predilection, extraoral involvement, and the results of diagnostic tests allow us to trace the clinical, demographic, and diagnostic profile of PV and MMP that contributes to differential diagnosis and therapeutic management.

Teleost Muc2 and Muc5ac: Key guardians of mucosal immunity in flounder (Paralichthys olivaceus).

Mucins secreted by mucous cells constitute a core part of the defense line against the invasion of pathogens. However, mucins' structure and immunological functions remain largely unknown in teleost fish. In this study, two typical mucins, Muc2 and Muc5ac of flounder (Paralichthys olivaceus), were cloned and their physicochemical properties, structure and conservation were analyzed. Notably, specific antibodies against flounder Muc2 and Muc5ac were developed. It was verified at the gene and protein level that Muc2 was expressed in the hindgut and gills but not in the skin, while Muc5ac was expressed in the skin and gills but not in the hindgut. After flounders were immunized by immersion with inactivated Edwardsiella tarda, Muc2 and Muc5ac were significantly upregulated at both the gene expression and protein levels, and Muc2+/Muc5ac+ mucous cells proliferated and increased secretion of Muc2 and Muc5ac. Moreover, Muc2 and Muc5ac exerted retention and clearance effects on E. tarda in a short period (within 1 dpi). These results revealed the characterization of fish mucins Muc2 and Muc5ac at the protein level and clarified the role of mucins as key guardians to maintain the mucus barrier, which advanced our understanding of teleost mucosal barrier.

Unveiling the secrets of gastrointestinal mucous adenocarcinoma survival after surgery with artificial intelligence: A population-based study.

BACKGROUND: Research on gastrointestinal mucosal adenocarcinoma (GMA) is limited and controversial, and there is no reference tool for predicting postoperative survival. AIM: To investigate the prognosis of GMA and develop predictive model. METHODS: From the Surveillance, Epidemiology, and End Results database, we collected clinical information on patients with GMA. After random sampling, the patients were divided into the discovery (70% of the total, for model training), validation (20%, for model evaluation), and completely blind test cohorts (10%, for further model evaluation). The main assessment metric was the area under the receiver operating characteristic curve (AUC). All collected clinical features were used for Cox proportional hazard regression analysis to determine factors influencing GMA's prognosis. RESULTS: This model had an AUC of 0.7433 [95% confidence intervals (95%CI): 0.7424-0.7442] in the discovery cohort, 0.7244 (GMA: 0.7234-0.7254) in the validation cohort, and 0.7388 (95%CI: 0.7378-0.7398) in the test cohort. We packaged it into Windows software for doctors' use and uploaded it. Mucinous gastric adenocarcinoma had the worst prognosis, and these were protective factors of GMA: Regional nodes examined [hazard ratio (HR): 0.98, 95%CI: 0.97-0.98, P < 0.001)] and chemotherapy (HR: 0.62, 95%CI: 0.58-0.66, P < 0.001). CONCLUSION: The deep learning-based tool developed can accurately predict the overall survival of patients with GMA postoperatively. Combining surgery, chemotherapy, and adequate lymph node dissection during surgery can improve patient outcomes.

Periodontal and microbiological data in patients with mucous membrane pemphigoid in a French population in 2021-2022: A pilot cross-sectional study.

Background and Aims: In the case of mucous membrane pemphigoid with gingival expression (gMMP), the complete healing of the gingiva is generally not achieved despite medical treatment. Therefore, patients' oral comfort is impaired. The dysbiotic periodontal microbiota, generated by a lack of oral hygiene associated with persistent gingival pain, could the immunopathological mechanism to persist. The main objective of this study was to characterize the subgingival microbiota of the gMMP patients, and to highlight a potential link between this microbiological data and the clinical data. Methods: Subgingival biofilm was collected from 15 gMMP patients, medically treated or not, but not receiving periodontal treatment. The usual clinical periodontal parameters were recorded. The biofilm was analyzed by polymerase chain reaction quantitative. The risk factors of severe erosive gingivitis and severe periodontitis were assessed using Chi-square or Fischer's exact test were used. Results: Whatever the medical and periodontal conditions of the patients, the results showed the existence of three main communities of periodontopathic, dysbiotic bacteria. The first including Tannnerella forsythia, Peptostreptococcus micros, Fusobacterium nucleatum, and Campylobacter rectus, was found in 100% of the patients, the second enriched with Treponema denticola in 60% and the third enriched with Porphyromonas gingivalis and Prevotella intermedia in 26%. Furthermore, there was a significant positive link between the duration of gMMP and the severity of erosive gingivitis (p = 0.009), and the loss of deep periodontal tissue (p = 0.04). Conclusion: This pilot study suggests a high periodontal risk in gMMP patients. The pathological processes, autoimmune on the one hand and plaque-induced on the other, may amplify each other. The application of periodontal therapy is therefore necessary in parallel with medical treatment. Nevertheless, further controlled studies are required to validate and complement these preliminary results.

Clinical Characteristics of Ocular Mucous Membrane Pemphigoid: A Systematic Review and Meta-Analysis.

PURPOSE: To synthesize the evidence and generate a combined weighted measure on the frequency of ocular manifestations of mucous membrane pemphigoid (OMMP). METHODS: Systematic literature review and meta-analysis, searching PubMed, Embase, VHL, and Google Scholar. Articles reporting patients with mucous membrane pemphigoid and ocular involvement were included. At least, two reviewers independently and in parallel participated in all the following phases; preliminary screening, full-text review, risk of bias assessment by validated tools, and data extraction. Qualitative analysis and meta-analysis were conducted. This study was previously registered in PROSPERO (CRD42023451844). RESULTS: Thirty-five studies met the inclusion criteria, comprising 1,439 patients and 1,040 eyes summarized in qualitative analysis. Twenty-eight studies were included in the meta-analysis. Ages included ranged from 60.4 to 75 years. Women were reported with more frequency. The mean time for diagnosis was 55.1 months, usually with bilateral ocular disease in 90% (95% CI 78%; 96%). Trichiasis and entropion were the most frequent manifestations in up to 92%, followed by symblepharon and punctate keratitis. Ankyloblepharon, persistent epithelial defects, and visual impairment were less frequent complications. Direct immunofluorescence positivity in conjunctival biopsies was 54% (95% CI 43%; 64%). Extraocular involvement was highly frequent, being oral and skin involvement the most frequently reported. CONCLUSIONS: Our systematic review and meta-analysis evidenced that patients around 60 years of age are the most affected population with a female preponderance, usually with bilateral ocular involvement. Trichiasis and entropion were the most frequent findings; although visual impairment and persistent epithelial defects were less reported, they should not be overlooked in suspected OMMP.

Prevalence of limbal stem cell deficiency at an academic referral center over a two-year period.

Aim: To evaluate the prevalence and clinical characteristics of limbal stem cell deficiency (LSCD) in the setting of a tertiary referral cornea practice at an academic center. Patient and methods: A retrospective chart review was performed to identify all unique medical record numbers (MRNs) presenting to a single cornea specialist (JHH) at the University of Minnesota during calendar years 2019 and 2020. Records were queried and confirmed for a diagnosis of LSCD. Clinical characteristics of identified patients, including demographics, etiology of LSCD, severity of LSCD, treatment, and best corrected visual acuity (BCVA) at final follow-up, were documented. Results: In total 1436 unique MRNs were identified over the study period. There were 61 individuals (91 eyes) diagnosed with LSCD, resulting in a prevalence of 4.25% (95% CI, 3.33-5.42). Of 91 eyes, 60 eyes were bilateral (65.9%). Among all eyes, ocular surface burns were the most common etiology (18.7%) followed by iatrogenic or medicamentosa (15.4%). There were 51 eyes (56.0%) that underwent some form of transplantation. The median BCVA at final follow-up was Snellen 20/80 (range 20/20 to no light perception). Conclusions: The prevalence of LSCD found at a cornea subspecialty tertiary referral center in our study was much higher than previously reported prevalence rates. This may reflect referral bias and potential underdiagnosis of LSCD in practices outside of subspecialty referral centers. The high prevalence rate in our study also suggests that LSCD patients are concentrated in subspecialty referral practices, with many having high morbidity disease. This constitutes a major health burden for these practices.

Croco Eye Technique: Mucous Retention Cyst Excision with Immediate Open Sinus Lift-A Retrospective Cohort Study.

Objectives: A mucous retention cyst is a common, asymptomatic lesion that may cause complications during or after the sinus lift procedure. The goal of this study is to assess the effectiveness of the Croco Eye Technique (CET), which allows simultaneous excision of the cyst and sinus floor elevation. Methods: The technique was thoroughly described in two versions, and the group of 33 patients was analyzed. Patients who qualified for this procedure had insufficient alveolar ridge height, and their CBCT showed radiological images typical for retention cysts. Analyzed parameters included the version of CET, demographic data, anatomical parameters, intraoperative complications, recurrence of the cyst, success rate of the sinus lift and implants, and the follow-up period. Results: Out of the 33 cases, 9 were of the primary version (27.27%) and 24 of the final version (72.73%). The average height of a retention cyst was 24.05 mm, with the average alveolar ridge height of 1.86 mm. In three cases (9.09%), implants were placed immediately. The prevalence of uncontrolled Schneiderian membrane perforation was reduced from 55.56% to 4.17% between the primary and final versions. The cyst's recurrence rate was 3.13%. The implant survival rate was 100%. The mean follow-up period was 48.625 months (max 110 months). Conclusions: The Croco Eye Technique, despite the perforation of the Schneiderian membrane, enables successful sinus lift and implantation with a success rate of 100%. Excision of the retention cyst, which is the cause of perforation, allows for limiting the risk of the cyst's recurrence.

Red dichromatic imaging and linked color imaging as reliable image-enhanced endoscopic procedures for detecting the distal end of the palisade vessels in the columnar metaplastic mucosa of the gastroesophageal junction zone.

BACKGROUND: There is a consensus that identifying the distal end of the palisade vessels (DEPV) is important for diagnosing gastroesophageal junction (GEJ). However, optimum observation methods have not been established. This study investigated the use of effective image-enhanced endoscopy (IEE) for DEPV detection. METHODS: One hundred endoscopic images in 20 cases of columnar metaplastic mucosa of the GEJ recorded with white-light imaging (Olympus-WLI and Fujifilm-WLI) and IEEs (narrow-band imaging; RDI1/2/3, red dichromatic imaging; texture and color enhancement imaging 1/2; blue-laser imaging; and LCI, linked color imaging) from two manufacturers were extracted and evaluated by 10 evaluators. Up to 24 radial straight lines from the center of the lumen were placed on the image, and the evaluators placed markings according to confidence level (high, low, and not detectable) at the DEPV locations. The detectability and reproducibility at the rate of the confidence level and coefficient of variance of markings among the evaluator were analyzed. RESULTS: In total, 15,180 markings were obtained. In terms of detectability, RDI1 (49.4%), RDI2 (53.0%), RDI3 (54.1%), TXI2 (49.7%), and LCI (34.6%) had a significantly higher rate of high confidence among the IEEs in each manufacturer. By contrast, Olympus-WLI (40.6%), Fujifilm-WLI (17.6%), narrow-band imaging (15.9%), and blue laser imaging (9.8%) presented with a significantly lower rates of high confidence. Regarding reproducibility, RDI3 and LCI had the lowest coefficient of variance for each manufacturer. CONCLUSIONS: RDI and LCI could be reliable modalities for detecting DEPVs in the columnar metaplastic mucosa of the GEJ zone.

Blind Curettage Technique for Treatment of Mucous Cysts Associated with Heberden Nodes: Description of Operative Technique.

The standard treatment for mucous cysts with Heberden nodes is excision of the dorsolateral osteophytes and capsule of the distal interphalangeal joint or thumb interphalangeal joint, including the stalk of the cyst. The skin incision varies for cases depending upon the geometry. We propose a surgical method utilizing blind lateral approaches for treating such mucous cysts.

A Retrospective Study of Glottic Cyst Histopathology and Its Clinical Presentation.

To understand the frequency and clinical presentation of the four types of vocal-fold cyst described by the Koren classification. Glottic cysts operated in a 1-year period were grouped retrospectively into Koren A, B, C and D (KA, KB, KC, KD). The age and sex of the patient, cyst location, laterality, associated lesions, profession, daily water consumption, duration of symptoms prior to surgery and postoperative healing time were noted. Of 30 cysts, 14 KA, 10 KB, 4 KC and 2 KD were identified. Average age of symptoms in KA to KD was 45, 52, 40 and 37 years. KC and KD were found only in females unlike the male predominance of KA and KB. Striking zone was the location of 28/30 cysts with a focal pit in 1 KC and mucosal bridge in 1 KD. There was no significance to laterality or profession. Average daily water consumption was 1.8, 1.75, 2 and 2 L in KA to KD. Average duration of symptoms up-till surgery for KA to KD was 2.6 years, 1.4 years, 2.9 years and 1 month. Post-operative healing time for KA to KD was 6.6, 7.4, 11.7 and 10 weeks. KA was the commonest cyst excised followed by KB, KC and KD. The KD patients were earliest and youngest to present. All KC and KD cysts were found in females unlike the male predominance of KA and KB. As majority of the cysts were found on the striking zone, phonotrauma may be one of the etiologies for all four cysts.

Digital mucous cyst.

Mucous cyst is a benign but recurrent lesion. It is located on the dorsal surface of the digital extremity between the distal interphalangeal joint and the base of the nail. The nail is often affected by the cyst because of its topographical proximity. Nail plate deformity may even be the first obvious abnormality indicating the presence of a small mucous cyst or subungual cyst. Mucous cyst is associated with osteoarthritis of the joint, osteophytes probably being the main contributing factor. Surgical treatment by joint debridement and cyst removal is the most effective way of preventing recurrence.

Effects of Postoperative Splinting on Outcomes following Digital Mucous Cyst Excision: A Retrospective Review.

Background: Digital mucous cysts (DMCs) are masses on the fingers that can be definitively managed with surgical excision. Though uncommon, surgical site infections can develop into septic arthritis. We sought to determine whether postoperative splinting decreases rates of postoperative infection and the need for postoperative antibiotics. We also explored the effect of age, gender, obesity, and preoperative antibiotic administration on infectious complications. Methods: Patients who underwent DMC excision between 2011 and 2021 were retrospectively identified. Chi-squared and Fisher's exact tests were used to analyze the complication rates including documented infection, postoperative antibiotic administration, mass recurrence, and return to operating room. Associations were analyzed between both preoperative antibiotic administration and postoperative splinting with respect to postsurgical complications. Results: The database search identified 373 patients who underwent 394 DMC excisions. Postoperative antibiotics were given in splinted patients at lower rates than their nonsplinted counterparts with a small-to-moderate effect size, but the difference was not statistically significant (2.7 vs. 7.5%). Preoperative antibiotic administration was not found to significantly affect the prescription of postoperative antibiotics. Splinting did not reduce rates of DMC recurrence. Patients who were splinted were more likely to have also received preoperative antibiotics. Males were given postoperative antibiotics more frequently than females (12.6 vs. 4.0%). Conclusions: Though not statistically significant, splinted patients were prescribed postoperative antibiotics less frequently. Postoperative antibiotics were utilized more frequently than the rate of infections typically reported following this procedure, possibly indicating overcautious prescription habits or underreported suspected infections.
