The Bosniak classification of renal cysts aims to provide a probabilistic risk assessment indicating the likelihood of malignancy from imaging findings. Originally designed to classify adult renal cysts based on computed tomography findings, the Bosniak classification has been extended to pediatric patients, with some adjustments made with the aim of accommodating magnetic resonance imaging (MRI) and ultrasonography (US). Bosniak IV lesions are rare in adolescents, indicating localized renal cell carcinoma and requiring surgical intervention. In contrast, Bosniak III lesions can be treated conservatively, although there is a lack of specific guidelines on their management. We present a case of a 14-year-old boy with a Bosniak III lesion, which was incidentally detected during the US evaluation of a left varicocele. After a 12-month follow-up, MRI revealed progression to a Bosniak IV cyst. Robot-assisted tumor enucleation was performed with selective artery clamping when the patient was 15. Histopathology showed tubulocystic renal cell carcinoma without adverse features. Immunocytochemistry supported a favorable prognosis of this rare tumor (<1% of renal tumor), thus obviating the need for adjuvant treatment. At the 18-month follow-up, no recurrence or distant metastasis were observed. This case highlights the importance of an aggressive treatment in persistent Bosniak III and Bosniak IV renal cysts in children and adolescents and the necessity to offer a nephron-sparing surgery.

Bone healing occurs through three consecutive and interdependent phases. While the acute inflammatory response is vital to fracture healing, chronic and systemic inflammation negatively affect the healing process. The bone tissue relies heavily on the immune system for its normal physiology and turnover. The interactions are more pronounced in injury states, such as fractures and autoimmune disorders. Recently, the field of osteoimmunology, the study of the molecular interplay of the immune and skeletal systems, has gained much-needed attention to develop new therapeutic strategies to accelerate fracture healing and prevent the complications of fracture healing. This review provides an overview of the process of fracture healing and discusses the role of immune cells, their interplay with the released cytokines, and the current state of the art in the field of osteoimmunology.

Peripheral developing odontoma is a rare odontogenic lesion that mostly occurs in children. Their clinical and radiological features generally provide clinical suspicion of a benign lesion but only a histological examination may lead to the final diagnosis. Surgical management is generally easy and resolutive, but it can become more complicated in uncooperative patients and may thus require additional procedures to perform a fit surgery. We report a case of peripheral developing odontoma of the palatal aspect of the anterior maxilla that occurred in an uncooperative child subsequently treated by diode laser surgery, highlighting the benefit of this kind of surgery in pediatric patients. Data from the literature on peripheral developing odontoma have been collected and discussed with a narrative review.

This study explores the innovative use of CO2 laser technology in frenuloplasty, a significant shift from classic methods like scalpel surgery or electrocautery towards a minimally invasive approach. The research involved 15 patients aged 25 to 50, undergoing frenuloplasty with a CO2 laser system equipped with a 7-inch defocused handpiece, set at 20 Hz and 0.3 W. This method diverges from conventional laser techniques, focusing on controlled laser passes combined with manual traction to elongate the fibrous tissue of the frenulum. The results demonstrated that the CO2 laser technique allowed for a precise and progressive modification of the frenulum, significantly reducing the risks of hemorrhage and secondary intention fibrosis. The healing process was notably expedited, with patients reporting satisfactory outcomes within a two-week period. Statistically significant improvements were observed in patient-reported outcomes, as evidenced by the increases in the Short Form Health Survey (SF-12) scores, with the mean Physical Component Summary (PCS) score rising from 32.5 to 47.5 and the mean Mental Component Summary (MCS) score from 39.3 to 52.3 (p < 0.001 for both). The study concludes that CO2 laser frenuloplasty is an effective and safe technique, offering substantial benefits in terms of reduced healing time and enhanced patient satisfaction. The significant improvements in SF-12 scores underscore the positive impact on patient quality of life, advocating for the broader application of this technique in clinical practice. Further research is warranted to explore its potential in a wider clinical context.

Objective: This systematic review was carried out with the primary objective of verifying which suture (polyamide or silk) of two non-resorbable suture materials with different structures had better/greater tensile strength/resistance to tension, thereby presenting better mechanical behavior. The secondary objective was to verify which one had better performance. The null hypothesis was that both types of sutures had the same behavior. Methods: This systematic study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards. The focused clinical question was: “In patients that underwent oral surgery treatment (P), is there significantly higher tensile strength/resistance for silk sutures (I) or for polyamide sutures (C) when comparing the outcomes (O)?” The bibliographic search was conducted on ScienceDirect, B-On, and PubMed/MedLine between March and May 2023. The following MeSH terms were defined: sutures, breaking strength, tensile strength, oral surgery, and dentistry, which were articulated and combined using Boolean operators. There were restrictions, such as articles published in Portuguese, Spanish, or English between 1 January 2018 and 3 April 2023. The quality assessment involved the use of the Joanna Briggs Institute (JBI) checklist for RCTs and the QUIN tool (Quality Assessment Tool For In Vitro Studies) for in vitro assays. Results: Ten articles were included in this review (eight in vitro studies and two RCTs). For the RCTs, there were moderate and high levels of bias, whereas in the in vitro studies, three were classified as having a high risk of bias and five as moderate risk. The results proved that suture thread with a monofilament polyamide physical structure causes a less inflammatory reaction owing to less bacterial retention and capillarity, while multifilament sutures, such as silk, have superior mechanical characteristics. Regarding hydration, the evidence demonstrated that the preservation and stability of mechanical properties lacked uniformity. Otherwise, hyaluronic acid (HA) presents a promising solution with the same characteristics and antibacterial capabilities. Conclusion: It was possible to reject the null hypothesis that both types of sutures had the same behavior and result. It was proven by the results above that sutures with a monofilament polyamide physical structure cause a less inflammatory reaction owing to less bacterial retention and capillarity. In contrast, multifilament sutures (silk) have superior mechanical characteristics. Regarding hydration using chlorohexidine in surgical sites, the evidence demonstrated in the preservation and stability of mechanical properties lacks uniformity and congruence. However, HA seems to present a promising option with the same characteristics and antibacterial capabilities.

Background: Carotid body tumors (CBTs) are rare benign tumors that arise from the chemoreceptor tissue located at the carotid bifurcation that require excision if symptomatic. Depending on the size and location of the tumor, the carotid artery may need to be repaired after resection. This study aims to assess whether CBT excision with artery resection had higher rates of 30-day postoperative outcomes compared with CBT excision without artery resection. Methods: This is a retrospective cohort study. Patients were identified in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) registry from 2005 to 2017. They were divided into two groups, based on Current Procedural Terminology (CPT®) codes: group A had CBT excision without carotid artery excision (CPT code 60600) and group B with carotid artery excision (CPT code 60605). Patient demographic characteristics, co-morbidities, and 30-days postoperative outcomes were compared between the two groups. Categorical data were analyzed using Pearson’s X2 or Fisher exact tests and presented as proportions (percentages). Continuous data were analyzed using parametric or non-parametric tests as appropriate. Statistical significance was defined as p < 0.05. Statistical analysis was performed using the SPSS statistical software package. Results: A total of 463 patients were identified, 410 (88.4%) in group A and 53 (11.4%) in group B. Overall, there were 291 (62.9%) women. A higher proportion of women underwent CBT excision only, compared to men (91.1% [265/291] vs. 84.3% [145/172], p < 0.0001). Demographics and comorbidities were similar between groups. There was no significant difference in the 30-day postoperative outcomes. The reoperation rate was higher in group B (3.8% vs. 1.5%, p = 0.334), while the readmission rate was higher in group A (3.2% vs. 0% p = 0.269), and both were not significantly different. Overall morbidity and serious morbidity were higher in group B (7.5% vs. 5.9%, p = 0.626) and lower in group A (5.7% vs. 3.9%, p = 0.544), respectively, but were not significantly different. Operative time (mean, SD) was higher in group B (187 ± 107 vs. 138 ± 66 min, p < 0.001). However, the median (IQR) of hospital length of stay (LOS) was similar (2 [1, 4] vs. 2 [1, 3] days, p = 0.134). Conclusions: Overall, no difference was noted in the 30-day postoperative outcome between the two surgical approaches of CBT. However, operative time was longer when artery resection was performed. Further research to determine the factors predicting the need for carotid artery resection among patient gender is needed.

Antihypertensive agents are commonly prescribed to manage hypertension and are known to be beneficial for bone formation and remodeling. The aim of this systematic review was to assess the impact that antihypertensive agents have on dental implant stability, osseointegration, and survival outcomes. A review of the literature was conducted using articles from 11 data sources. PRISMA guidelines were followed, and a PICO question was constructed. The search string “Antihypertensive* AND dental implant* AND (osseointegration OR stability OR survival OR success OR failure)” was used for all data sources where possible. The Critical Appraisal Skills Programme (CASP) was used for study appraisal, including the risk of bias. The search resulted in 7726 articles. After selection according to eligibility criteria, seven articles were obtained (one randomized control trial, two prospective cohort studies, three retrospective cohort studies, and a case control study). Five papers investigated the effects of antihypertensive agents on primary stability, but there were discrepancies in the method of assessment. Inhibition of the renin–angiotensin–aldosterone system was linked to higher primary stability. Secondary stability was usually higher than primary stability, but it is unknown if antihypertensive agents caused this. Survival outcomes were increased with certain antihypertensive agents. It is possible that inhibition of the renin–angiotensin–aldosterone system may lead to greater bone mineral density, improved primary stability, and improved survival outcomes although the effects on osseointegration are unknown. However, more research is needed to confirm this theory.

Chylothorax is a rare condition where the extravasated chyle accumulates into the pleural space. It is most commonly associated with malignancies, infective or inflammatory disorders and iatrogenic causes. Extremely rarely, it could occur spontaneously. We present the case of a healthy 40-year-old woman who presented with acute right shoulder and neck pain associated with shortness of breath and loss of consciousness. This was preceded by a yoga class two weeks prior. Chest imaging showed right pleural effusion, and tapping revealed a milky fluid which was confirmed to be chylothorax. Conservative management failed and the patient was successfully treated with video-assisted thoracoscopic drainage, thoracic duct ligation and mechanical pleurodesis. Chylothorax association with yoga is not reported in the literature.
