Oronasal fistulas are sequelae to periodontal disease in dogs. Previous case series have described the use of auricular cartilage as a type of membrane to help with surgical repair of oronasal fistulas. This case series explores the use of a commercially available flexible bone membrane in the surgical repair of ten acquired oronasal fistulas in dogs. The use of the flexible bone membrane did not necessarily improve the surgical outcomes in these cases; however, larger controlled trials are necessary to further evaluate its use.

OBJECTIVE The tumor characteristics and surgical outcomes of intracranial subependymomas are poorly defined. In this study the authors aimed to provide a comprehensive review of all clinical, pathological, radiological, and surgical aspects of this important neoplasm to inform future management strategies. METHODS A systematic review and meta-analysis of MEDLINE, EMBASE, Cochrane, and Google Scholar databases adherent to PRISMA guidelines was conducted. RESULTS Of the 1145 articles initially retrieved, 24 studies encompassing 890 cases were included. The authors identified 3 retrospective cohort studies and 21 case series, but no controlled trials. Mean age at presentation was 46.7 ± 18.1 years with a male predominance (70.2%). Common sites of tumor origin were the lateral ventricle (44.5%) and fourth ventricle (43.1%). Cumulative postoperative mortality and morbidity rates were 3.4% and 24.3% respectively. Meta-analysis revealed that male sex (HR 3.15, 95% CI 1.39–7.14, p = 0.006) was associated with poorer 5-year overall mortality rates. All-cause mortality rates were similar when performing subgroup meta-analyses for age (HR 0.50, 95% CI 0.03–7.36, p = 0.61), smaller subependymoma size (HR 1.51, 95% CI 0.78–2.92, p = 0.22), gross-total resection (HR 0.65, 95% CI 0.35–1.23, p = 0.18), and receipt of postoperative radiation therapy (HR 0.88, 95% CI 0.27–2.88, p = 0.84). Postoperative Karnofsky Performance Index scores improved by a mean difference of 1.62 ± 12.14 points (p = 0.42). The pooled overall 5-year survival rate was 89.2%, while the cumulative recurrence rate was 1.3% over a median follow-up ranging from 15.3 to 120.0 months. The pure subependymoma histopathological subtype was most prevalent (85.6%), followed by the mixed subependymoma-ependymoma tumor variant (13.7%). CONCLUSIONS Surgical extirpation without postoperative radiotherapy results in excellent postoperative survival and functional outcomes in the treatment of intracranial subependymomas. Aggressive tumor behavior should prompt histological reevaluation for a mixed subependymoma-ependymoma subtype. Further high-quality controlled trials are still required to investigate this rare tumor.

Relevance. The modern view of periodontitis as a dysbiotic disease that occurs as a result of changes in the microbial composition of the subgingival region is considered in a systematic review.Purpose. To study a new paradigm of development of generalized periodontitis.Materials and methods. Randomized controlled trials (RCTS) were selected for the study, including cluster RCTS, controlled (non-randomized) microbiological and clinical studies of the oral microbiome in adult patients with generalized periodontitis over the past 10 years.Results. The transition from a symbiotic microflora to a dysbiotic pathogenic community triggers the host's inflammatory response, which contributes to the development of periodontal diseases. Modern ideas about periodontal pathogenic bacteria dictate new requirements for the treatment of periodontal diseases. The second part of the review examines the microbial profiles of periodontal disease in various nosological forms, the mechanisms of the immune response and approaches to the treatment of periodontal disease from the perspective of biofilm infection.Conclusions. As follows from modern literature periodontitis is to a certain extent caused by the transition from a harmonious symbiotic bacterial community to a dysbiotic one. Recent scientific studies have shown that not single microorganism is not able to cause disease but the microbial community as a whole leads to the development of pathology.

Introduction Lesser tuberosity osteotomy (LTO) during anatomic total shoulder arthroplasty has a 13% nonunion rate. Treatment for LTO nonunion is controversial and poorly described in the literature. The purpose of this study was to compare the surgical and nonsurgical treatment outcomes of LTO nonunion. Methods A retrospective case series of 9 consecutive patients with LTO nonunion after primary anatomic shoulder arthroplasty at 1 institution from 2010 to 2016 were studied. Outcomes measured were radiographic evaluation of LTO on axillary X-ray, clinical range of motion (ROM), subscapularis strength, and pain at the time of LTO nonunion diagnosis and after either conservative care or surgical repair of the LTO nonunion. Results LTO nonunion was treated surgically in 4 and conservatively in 5 patients with average follow-up of 30 and 22 months, respectively. There were no significant differences in age, sex, or smoking status between groups. Treatment decision was a shared model of surgeon and patient. Displaced LTO nonunion was treated surgically in 2 and conservatively in 3 patients. There were no differences in LTO union rate of 50% in the surgical versus 60% in the conservative group. Abdominal compression test was abnormal in 50% of surgical versus 40% of conservative groups. At follow-up, ROM was lower in the surgical group with 128° forward elevation (FE) and 33° external rotation (ER) compared to 148° FE and 62° ER. Only 1 patient with LTO nonunion required conversion to reverse replacement. Conclusion LTO nonunion after shoulder arthroplasty is rare. Surgical repair of LTO nonunion does not significantly improve clinical or radiographic outcomes compared to conservative care.

We compared surgical outcomes in patients with either primary open-angle glaucoma or exfoliation glaucoma after undergoing combined phacoemulsification with either a 120° or 180° incision during a Schlemm’s canal microhook ab interno trabeculotomy (μLOT-Phaco). This retrospective comparative case series examined 52 μLOT-Phaco eyes that underwent surgery between September 2017 and December 2020. Surgical qualified success was defined as an intraocular pressure (IOP) of ≤20 mmHg, ≥20% IOP reduction with IOP-lowering medications, and no additional glaucoma surgery. Success rates were evaluated by Kaplan-Meier survival analysis. The number of postoperative IOP-lowering medications and occurrence of complications were also assessed. Mean preoperative IOP in the 120° group was 16.9 ± 7.6 mmHg, which significantly decreased to 10.9 ± 2.7 mmHg (p < 0.01) and 11.1 ± 3.1 mmHg (p = 0.01) at 12 and 24 months, respectively. The mean number of preoperative IOP-lowering medications significantly decreased from 2.8 ± 1.4 to 1.4 ± 1.4 (p < 0.01) at 24 months. Mean preoperative IOP in the 180° group was 17.1 ± 7.0 mmHg, which significantly decreased to 12.1 ± 3.2 mmHg (p = 0.02) and 12.9 ± 1.4 mmHg (p = 0.01) at 12 and 24 months, respectively. The mean number of preoperative IOP-lowering medications significantly decreased from 2.9 ± 1.2 to 1.4 ± 1.5 (p < 0.01) at 24 months. The probability of qualified success at 24 months in the 120° and 180° groups was 50.4% and 54.6%, respectively (p = 0.58). There was no difference observed for hyphema formation or IOP spikes. Surgical outcomes were not significantly different between the 120° and 180° incisions in Schlemm’s canal.

Abstract Purpose Trans-hiatal herniation after esophago-gastric surgery is a potentially severe complication due to the risk of bowel incarceration and cardiac or respiratory complaints. However, measures for prevention and treatment options are based on a single surgeon´s experiences and small case series in the literature. Methods Retrospective single-center analysis on patients who underwent surgical repair of trans-hiatal hernia following gastrectomy or esophagectomy from 01/2003 to 07/2020 regarding clinical symptoms, hernia characteristics, pre-operative imaging, hernia repair technique and perioperative outcome. Results Trans-hiatal hernia repair was performed in 9 patients following abdomino-thoracic esophagectomy (40.9%), in 8 patients following trans-hiatal esophagectomy (36.4%) and in 5 patients following conventional gastrectomy (22.7%). Gastrointestinal symptoms with bowel obstruction and pain were mostly prevalent (63.6 and 59.1%, respectively), two patients were asymptomatic. Transverse colon (54.5%) and small intestine (77.3%) most frequently prolapsed into the left chest after esophagectomy (88.2%) and into the dorsal mediastinum after gastrectomy (60.0%). Half of the patients had signs of incarceration in pre-operative imaging, 10 patients underwent emergency surgery. However, bowel resection was only necessary in one patient. Hernia repair was performed by suture cruroplasty without (n = 12) or with mesh reinforcement (n = 5) or tension-free mesh interposition (n = 5). Postoperative pleural complications were most frequently observed, especially in patients who underwent any kind of mesh repair. Three patients developed recurrency, of whom two underwent again surgical repair. Conclusion Trans-hiatal herniation after esophago-gastric surgery is rare but relevant. The role of surgical repair in asymptomatic patients is disputed. However, early hernia repair prevents patients from severe complications. Measures for prevention and adequate closure techniques are not yet defined.

Purpose. The black iris-lens diaphragm (ILD) can be used in the treatment of traumatic aniridia and aphakia. The aim of our study was to show postoperative functional and anatomic results and complications in a small case series. Methods. We retrospectively analyzed the files of 16 patients managed with a black ILD or a sole iris diaphragm in the period 1994–2007. Four of them were female and 12 were male. The mean age of the group was 50±17 years. At the time of the implantation, all of the eyes had already undergone primary surgical repair. Results. The preoperative best-corrected visual acuity in half of the patients was ≥0.1 and remained stable after the first postoperative year. During the follow-up years, one eye developed a subluxation of the implant and one eye an anterior chamber hemorrhage. At the same time, out of 8 eyes carrying a silicone tamponade in the vitreous cavity, silicone oil entered the anterior chamber in 3 cases. In one case, enucleation was undertaken due to phthisis. Conclusions. In the case of severely traumatized eyes with aniridia and aphakia, the implantation of a black ILD can have a positive effect on functional and anatomic stabilization.

Background and objectivesVideo-based telemedicine provides an alternative health care delivery model for patients with CKD. The objective was to provide an overview of the available evidence on the implementation and outcomes of adopting video-based telemedicine in nephrology.Design, setting, participants, & measurementsMEDLINE, EMBASE, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, and CINAHL were searched in December 2019 and again in January 2021 for studies using video-based telemedicine for adults across the spectrum of kidney disease. Study types included peer-reviewed clinical trials, observational studies, and descriptive studies available in full text. Search results were independently screened by two authors, who then independently reviewed and extracted data from the eligible studies. Results were synthesized in tabular format, summarizing study characteristics by area within nephrology; the video-based interventions used; and clinical, health care utilization, and patient-reported outcomes.ResultsAfter reviewing 1870 unique citations, 24 studies were included (four randomized controlled trials, six cohort studies, five pre-post intervention studies, seven case series, and two qualitative studies). Video-based technology was used to facilitate care across all stages of CKD. Although earlier studies used a range of institution-specific technologies that linked main hospital sites to more remote health care locations, more recent studies used technology platforms that allowed patients to receive care in a location of their choice. Video-based care was well received, with the studies reporting high patient satisfaction and acceptable clinical outcomes.ConclusionsVideo-based telemedicine is being used for kidney care and has evolved to be less reliant on specialized telemedicine equipment. As its use continues to grow, further primary studies and systematic reviews of outcomes associated with the latest innovations to video-based care in nephrology can address knowledge gaps, such as approaches to sustainable integration and minimization of barriers to access.
