Background and Purpose: Undescended testes (UDT) is recognized as the most prevalent anomaly of the male genitalia and presents a significant risk factor for long-term complications, including infertility and testicular cancer. Currently, there is no consensus on the necessity of imaging in the management of UDT, nor is there agreement on which imaging modality is preferred or to what extent these tests offer real added value in the clinical setting. This review aims to evaluate the various imaging options available in the management of cryptorchidism, discussing their utility, advantages, and disadvantages compared to exploratory laparoscopy. Methods: We conducted a PubMed search using the following search terms: [“undescended testis”] OR [(“cryptorchidism”) OR (“diagnostic imaging”)] OR [(“Ultrasound”), OR (“CT scan”) OR (“MRI”)] AND [“laparoscopy”]. We analyzed 90 full articles, excluding irrelevant ones, and, in total, 18 publications were included in this review. Results: Ultrasound (US) is the most commonly used technique due to its non-invasive nature and absence of ionizing radiation. It is particularly beneficial in cases of non-palpable UDT. However, its main limitation lies in the difficulty in accurately locating UDT, especially when they are situated outside the inguinal region. Computed tomography (CT) scans serve as a crucial diagnostic tool, particularly for testes located below the internal inguinal ring. While CT exhibits comparable accuracy in detecting UDT, the need for sedation or general anesthesia, along with the costs and potential risks of secondary malignancy due to radiation exposure, does not favor its routine use. Magnetic resonance imaging (MRI) offers higher sensitivity than US and does not utilize ionizing radiation or intravascular contrast agents. It allows for the generation of multiplanar images, thereby providing improved tissue characterization. However, limitations include prolonged scan durations, the potential for motion artifacts during imaging, the need for sedation, and higher costs. Laparoscopy has been shown to provide better accuracy, offering both diagnostic and therapeutic benefits, particularly in cases of non-palpable UDT. It is widely regarded as the gold standard in achieving clear diagnostic and definitive therapeutic procedures and has demonstrated its utility in determining the anatomical position of intra-abdominal testes, owing to its magnification capabilities and minimally invasive approach. Conclusions: Achieving a correct and comprehensive diagnosis of cryptorchidism requires the medical team to decide on the appropriate imaging studies, as these will not significantly influence or alter the therapeutic decision-making process. It is unlikely that medical practice will eliminate imaging studies before a surgical decision is made in the near future. Therefore, a multidisciplinary approach that includes clinical examination, imaging, and diagnostic laparoscopy remains essential for the accurate management of UDT. Full article

Introduction: The objective of the present work is to assess the efficacy of photobiomodulation (PBM) with respect to pain, inflammation, and healing after tooth extractions as compared with a sham treatment. Method: A single-blinded, randomized clinical study conducted in a private dental clinic in Murcia, it included 124 patients who needed a tooth extraction, excluding those with medical conditions that could affect healing (such as non-controlled diabetes, immunosuppression, or hemorrhagic disorders). Group I (Experimental): extraction and PBM session with a diode laser (power: 0.5 W, energy 15 J/cm² for 10–30 s at 1 mm from the tissue). Group II (Sham treatment): tooth extraction and application of inactive PBM. Results: Pain and inflammation decreased similarly in both groups over time. Anxiety decreased in both groups without significant differences (p = 0.776; p = 0.246). There was no evidence that the treatment or location of the extraction had an influence on healing. Suturing the socket increased the likelihood of good healing (p = 0.048), while long procedures reduced it (p = 0.040). Conclusions: PBM is a non-invasive and safe therapy. This study did not show significant differences with respect to the sham treatment. More research is needed with a standardized methodology to better assess its efficacy. Full article

High-intensity focused ultrasound (HIFU) is a non-invasive technology widely used for facial and body rejuvenation, skin tightening, and fat reduction. It stimulates collagen production and induces apoptosis in fat cells, offering an effective alternative to surgical procedures with minimal downtime and reduced recovery periods. As a result, HIFU has become an increasingly popular choice for patients seeking non-surgical esthetic enhancements. A comprehensive literature search was conducted using PubMed, Scopus, and SpringerLink to assess HIFU-related complications. Twenty-two studies published between 2010 and 2025 were identified, all involving female participants. The findings confirm that HIFU is generally safe and effective, with most complications being mild and transient, such as temporary erythema, swelling, and discomfort. These side effects typically resolve within a few hours to days without requiring medical intervention. However, rare but significant complications like fat atrophy, nerve irritation, and hyperpigmentation have been linked to improper device settings, inadequate practitioner expertise, and insufficient patient assessment. Ensuring proper training, adherence to standardized treatment protocols, and individualized patient evaluations can significantly minimize these risks and optimize patient outcomes. Long-term follow-up studies and further research on standardized safety protocols, optimal energy settings, and patient selection criteria are essential for enhancing the effectiveness, predictability, and safety of HIFU in esthetic medicine.

Background/Objectives: The safe completion of a non-invasive procedure is crucial to the success of an endovascular approach. Chitosan, a natural polysaccharide derived from chitin, is an ideal material for the study and application of medical devices in post-operative wound management. Methods: The present work is based on a retrospective study conducted on a sample of patients treated with Axiostat (a sterile, single-use, non-absorbable dressing), composed of 100% chitosan and designed to instantly stop bleeding through a mucus adhesion mechanism for the treatment of conditions such as Leriche’s syndrome. The objective was to evaluate the efficacy and safety of the hemostatic Axiostat dressing in patients undergoing anticoagulant and/or antiplatelet therapy in whom endovascular procedures using the axillary artery as an access site are performed to treat Leriche syndrome. Results: The obtained results showed that Axiostat is safe and effective in promoting hemostasis at the axillary vascular access site even when prolonged hemostasis was required in patients on antiplatelet and anticoagulant therapy. The mean time to hemostasis was 5.75 min in all types of patients considered. Full article

Background: Interventional electrophysiology is a rapidly advancing field, with sedation essential for patient comfort and immobility during complex electrophysiological procedures (EPS). However, sedatives and analgesics can cause respiratory depression and hypotension. Gender-specific differences (GDs) are often overlooked in medical research, as protocols and dosages are typically based on male subjects, potentially compromising treatment safety and efficacy for women. This study examines GDs in CO₂ levels, respiratory rate, arterial blood pressure (ABP), and anesthetic requirements during deep sedation for EPS. Methods: This prospective study at Ulm University Heart Center included 702 patients (405 men and 297 women) treated under deep sedation between August 2019 and October 2023. Standard monitoring included an electrocardiogram (ECG) with heart rate, non-invasive ABP, oxygen saturation (SpO₂), and a frequent venous blood gas analysis (vBGA). The primary composite endpoint was GDs in SpO₂ dips below 90% and pathological vBGA changes. Results: The primary composite endpoint was reached by 177 women (59.6%) and 213 men (52.6%), showing no significant difference (p = 0.102). Women had a 1,6-fold higher risk of experiencing SpO₂ dips below 90% (p = 0.001). Additionally, women had 1.7 times higher hypoxia rates (p < 0.001) and were 1.5 times more likely to have a mean ABP below 65 mmHg (p < 0.001). On average, they received 65.3 mg less total propofol than men (p = 0.005) and a higher midazolam dose per kilogram of body weight (p < 0.001). Conclusions: Although the primary composite endpoint showed no significant GDs, secondary outcomes highlight the need to consider gender-specific sedation adjustments, particularly for women. This study underscores the need for personalized sedation management and patient monitoring regarding GDs. Full article

Background/Objectives: Rhinogenic contact point headache (RCPH) is a controversial secondary headache disorder involving mucosal contact points in the nasal sinuses. The efficacy of surgical versus medical management has been debated, with some studies showing excellent long-term outcomes but others citing placebo effects. This study aimed to clarify the correlation with nasal anatomical variation detected by CT and RCPH treatment outcomes. Methods: A prospective cohort study was conducted on 90 RCPH patients undergoing surgery or medical therapy. Patients were diagnosed using CT scans, endoscopy, and lidocaine testing. The surgery group had endoscopic procedures to remove contact points. The medical group received intranasal steroids. Outcomes were measured by visual analog scale (VAS) for pain and headache frequency. Predictors like age, gender, and nasal anatomical variations were analyzed. Results: The surgery group showed significant reductions in VAS scores (6.02 to 2.51, p < 0.001) and headache frequency (9.11 to 3.04, p < 0.001). The medical group did not improve significantly. All nasal subtypes improved with surgery but concha bullosa had worse VAS outcomes (4.0) than septal deviation (1.8, p < 0.001) or spur (1.73, p < 0.001). Multivariate analysis found nasal anomalies predicted postoperative VAS scores (p < 0.001) but not headache frequency (p = 0.255). Conclusions: Surgery demonstrated superiority over medications for RCPH. This study provides new evidence that preoperative CT scans should be considered a non-invasive gold standard for analyzing nasal subtypes as they significantly influence surgical success, with concha bullosa associated with worse pain relief. Larger studies should validate these findings to optimize RCPH management. Full article

Background: Postoperative nausea and vomiting (PONV) remains a frequent and uncomfortable complication in women undergoing robotic gynecological procedures. Despite the use of various preventive strategies, PONV continues to negatively impact recovery and increase healthcare expenses. This study aimed to evaluate whether the preoperative use of sugar-free chewing gum could effectively minimize the dependence on anti-emetic drugs in women undergoing robot-assisted laparoscopic surgery for uterine myomas. Methods: In this randomized, single-blind study, 92 adult women scheduled for robot-assisted laparoscopic surgery were enrolled. The participants were randomly assigned to one of two groups: a gum-chewing group, which was instructed to chew sugar-free gum for 15 min in the preoperative holding area, or a control group that did not chew gum. The primary outcome was the requirement for anti-emetic medication within the first hour after surgery, when the patient was in the post-anesthesia care unit (PACU). Secondary outcomes included the overall frequency of anti-emetic use. To assess the intervention’s effectiveness independent of any other factors, no prophylactic anti-emetics were administered during surgery. Results: Of the 92 participants, 89 completed the study, with 44 assigned to the gum-chewing group and 45 to the control group. The gum-chewing group showed a significantly lower rate of PONV, requiring anti-emetic treatment (79.5%), compared to the control group (95.6%). Additionally, the control group demonstrated a higher overall need for anti-emetic medications. Notably, there were no reported adverse effects, such as jaw discomfort, dental injuries, or gastric regurgitation, in either group. Conclusions: Chewing sugar-free gum for 15 min prior to surgery was found to be a safe, simple, and effective method to reduce the occurrence of PONV in women undergoing robot-assisted laparoscopic surgery for benign uterine tumors. This non-invasive intervention reduced the reliance on anti-emetic drugs and improved patient comfort, without introducing risks. These findings suggest that preoperative gum chewing could be routinely implemented in clinical settings to enhance surgical outcomes. Full article

There is an ongoing search for a reliable and continuous method of noninvasive blood pressure (BP) tracking. In this study, we investigate the feasibility of utilizing seismocardiogram (SCG) signals, i.e., chest motion caused by cardiac activity, for this purpose. This research is novel in examining the temporal relationship between the SCG-measured isovolumic moment and the electrocardiogram (PEP_IM). Additionally, we compare these results with the traditionally measured pre-ejection period with the aortic opening marked as an endpoint (PEP_AO). The accuracy of the BP estimation was evaluated beat to beat against invasively measured arterial BP. Data were collected on separate days as eighteen sets from nine subjects undergoing a medical procedure with anesthesia. Results for PEP_IM showed a correlation of 0.67 ± 0.18 (p < 0.001), 0.66 ± 0.17 (p < 0.001), and 0.67 ± 0.17 (p < 0.001) when compared to systolic BP, diastolic BP, and mean arterial pressure (MAP), respectively. Corresponding results for PEP_AO were equal to 0.61 ± 0.22 (p < 0.001), 0.61 ± 0.21 (p < 0.001), and 0.62 ± 0.22 (p < 0.001). Values of PEP_IM were used to estimate MAP using two first-degree models, the linear regression model (achieved RMSE of 11.7 ± 4.0 mmHg) and extended model with HR (RMSE of 10.8 ± 4.2 mmHg), and two corresponding second-degree models (RMSE of 10.8 ± 3.7 mmHg and RMSE of 8.5 ± 3.4 mmHg for second-degree polynomial and second-degree extended, respectively). In the intrasubject testing of the second-degree model extended with HR based on PEP_IM values, the mean error of MAP estimation in three follow-up measurements was in the range of 7.5 to 10.5 mmHg, without recalibration. This study demonstrates the method’s potential for further research, particularly given that both proximal and distal pulses are measured in close proximity to the heart and cardiac output. This positioning may enhance the method’s capacity to more accurately reflect central blood pressure compared to peripheral measurements. Full article

Numerous studies highlight the significant role of exercise therapy in patients with peripheral artery disease (PAD), emphasizing how regular physical exercise enhances vascular endothelial function and promotes metabolic adaptations in skeletal muscles, ultimately improving walking performance. There are currently discussions in the medical world on optimizing noninvasive therapy to prevent the development of lower limb ischemia. This study aimed to assess the impact of a supervised training program combined with whirlpool massage treatment on improving peripheral circulation and physical performance in patients suffering from peripheral artery disease. Methods: One hundred participants (both male and female) aged between 39 and 79 years old (60.0 ± 11.6) were included in the analysis, all diagnosed with peripheral circulation disorders. The participants were assigned to two groups. The study group received 10 whirlpool treatments of the lower limbs and a personalized training program. The control group only participated in the training sessions. Pre- and post-intervention evaluations included impedance plethysmography and the six-minute walk test (6MWT). Results: Assessing the results of local flow parameters, after the procedures, a statistically significant increase in the pulse wave amplitude (PAmpl, p < 0.001) and systolic slope (PSlope, p < 0.001) values was found, as well as a statistically significant decrease in the crest time (CT, p < 0.001) and propagation time (PT, p = 0.007) values in the study group, which indicates an improvement in blood flow in the peripheral circulation. Also, in the 6 min walk test, a statistically significant increase in the walking distance was noted in the study group after the procedures. Conclusions: Physical training, combined with whirlpool massage treatment, has a beneficial effect on improving peripheral blood flow assessed by impedance plethysmography, as well as patients’ tolerance to physical exercise. The inclusion of hydrotherapy as part of cardiovascular rehabilitation protocols in patients with peripheral ischemia is a promising form of conservative treatment. Full article

Endometriosis is an oestrogen-dependent inflammatory disease affecting menstruating women, with varying levels of severity. Oestrogen dysregulation is responsible for chronic inflammation, angiogenesis, endometrial lesion development, progression, and infertility during menarche in afflicted women. The inflammatory mediators associated with this chronic painful disease have been established, with research also indicating the relationship between dysbiosis and disease manifestation. Endometriosis is also present with several painful comorbidities, including endometrial cancer, cardiovascular disease, and autoimmunity. The lack of specific and sensitive non-invasive diagnostic procedures, coupled with poor response to current therapeutic approaches, means that treatment needs remain unmet. Surgical procedures are performed to remove endometriosis ectopic lesions, for which the recurrence rate of disease is up to 50%, with certain patients exhibiting no alleviation of symptoms. This review aims to outline the aetiology of endometriosis, detailing novel diagnostic approaches and potential therapeutic approaches, namely advanced therapeutic medical products (ATMPs), including stem cell therapy and clustered regularly interspaced short palindromic repeats (CRISPR) gene editing. This timely review also provides novel insights into the important recent modalities which may be applied for the diagnosis and therapeutic response of endometriosis, including biomarkers, microfluidic platforms, and organoid systems. Undoubtedly, reliable, reproducible, sensitive, and specific models of endometriosis in humans are urgently needed to investigate and detail the aetiology of this debilitating disease. Full article

This literature review provides a novel exploration of zinc’s multifaceted roles in dermatology, with a particular focus on its potential integration into botulinum toxin formulations—an area that remains relatively underexplored in clinical practice. Zinc is widely recognized for its critical functions in skin health, including morphogenesis, regeneration, and protection, and its use in aesthetic medicine offers a unique opportunity for innovation. Specifically, incorporating zinc into botulinum toxin formulations could enhance the efficacy and stability of these treatments. Although zinc has historically been used in topical dermatological products and systemic health interventions, its potential in cosmetic preparations, such as anti-aging therapies or non-invasive aesthetic treatments, remains under-researched. Emerging patents suggest promising formulations combining zinc with botulinum toxin that may improve product stability and extend therapeutic effects. While current studies on oral zinc supplementation present mixed results concerning its ability to prolong botulinum toxin effects, this underscores the need for more rigorous investigation in the realm of aesthetic medicine. Zinc’s well-established role in stabilizing dermatological products, such as sunscreens, and its applications in wound healing and skin regeneration, further highlights its potential for broader therapeutic uses beyond cosmetic applications. This review identifies a critical gap in the literature and calls for future research to optimize zinc concentrations and delivery methods specifically for aesthetic medical procedures, offering new insights into improving dermatological treatments beyond the scope of traditional cosmetic preparations.

The Bee Cosmetic Surgery Scale (BCSS) is a novel clinical tool designed to assess the psychopathological, psychosocial, and decision-making factors involved in accepting cosmetic procedures. This prospective, multicenter study aimed to propose and validate the BCSS, which considers aesthetic aspects, personal pathological history, and psychopathological implications leading to the acceptance of invasive or non-invasive aesthetic interventions. The study included 281 participants aged 18–66 years, divided into three groups: non-invasive cosmetic surgery (NICS), invasive and non-invasive cosmetic surgery (INICS), and individuals who had not undergone cosmetic surgery (NCS). Participants were randomly selected from patients visiting plastic surgery services and various medical services in Oradea, Romania, between October 2022 and March 2024. The BCSS comprises 20 items with Likert-type responses, ranging from one to five. The Multidimensional Scale of Perceived Social Support (MSPSS) was used to measure perceived social support. The BCSS aims to elucidate the patient’s desire for aesthetic procedures, whether it stems from an impulsive act, warrants a longer decision-making period, or necessitates addressing psychological or psychiatric conditions before scheduling the procedure. The scale enables cosmetic surgeons to assess whether the patient has been adequately informed and understands the risks and complications associated with the cosmetic surgical procedure.

Purpose: Knowledge of the length of the colon is relevant to understanding physiological and pathological function. It also has implications for diagnostic and clinical interventions, as well as for the design of delayed-release drug formulations and drug disposition modeling. Methods: Over the years, a range of different experimental methods have been employed to assess colon length. These methods vary from direct measurements on cadavers and during intraoperative procedures to measurements obtained from endoscopic and medical imaging techniques. However, no systematic review or meta-analysis of these findings has yet been carried out. In this systematic review, we identified 31 published experimental studies that measured the length of the human colon and/or its segments. Results: We synthesized the available data, comprising colon length measurements from 5741 adults and 337 children and young people, in a meta-analysis. The data contribute to our understanding of colon morphology and may have implications for clinical practice, particularly for colonoscopy and preoperative planning of surgical resections. Additionally, this review provides potential insights into anatomical correlates of functional diseases, such as constipation. Conclusions: This review highlights that non-invasive, non-destructive diagnostic imaging techniques, such as magnetic resonance imaging (MRI), can provide more physiologically relevant measurements of colon length. However, there is a need for more standardized measurement protocols and for additional pediatric data. Full article

Atrial wall thickness (AWT) is a significant factor in understanding the pathological physiological substrate of atrial fibrillation, with a potentially substantial impact on the outcomes of catheter ablation procedures. Precise measurements of the AWT may provide valuable insights for categorising patients with AF and planning targeted interventions. Objectives: The purpose of this study was to evaluate the characteristics of the left atrium (LA) using non-invasive multidetector computed tomography (MDCT) scans and subsequent three-dimensional (3D) image post-processing using novel software designed to calculate atrial thickness dimensions and mass. Methods: We retrospectively analysed 128 consecutive patients (33.6% females; mean age 55.6 ± 11.2 years) referred for AF ablation (37 with persistent AF and 91 with paroxysmal AF) who underwent preprocedural MDCT. The images were post-processed and analysed using the ADAS software (Galgo Medical), automatically calculating the LA volume and regional wall thickness. In addition, the software employed a regional semi-automatic LA parcellation feature that divided the atrial wall into 12 segments, generating atrial wall thickness (AWT) maps per segment for each patient. Results: This study demonstrated considerable variability in the average thickness of LA walls, with the anterior segments being the thickest across the cohort. Distinct sex-specific differences were observed, with males exhibiting greater anterior and septal wall thickness than females. No significant associations were identified between the average AWT and body mass index, LA volume, or sphericity. Survival analysis conducted over 24 months revealed a meaningful relationship between mean anterior wall thickness and recurrence-free survival, with increased thickness associated with a lower likelihood of AF-free survival. No such relationship was observed for the indexed LA volume. Conclusions: The variability in AWT and its association with recurrence-free survival following AF ablation suggest that AWT should be considered when stratifying patients for AF management and ablation strategies. These findings underscore the need for personalised treatment approaches and further research on the interplay of the structural properties of the left atrium as factors that can serve as important prognostic markers in AF treatment.

The aim of this review is to present and discuss the use of optical coherence tomography angiography (OCTA) in age-related macular degeneration (AMD). OCTA is a non-invasive imaging procedure that gives a detailed indirect view of physiological and pathological vessels in the retina and choroid membrane. Compared with dye-based imaging, OCTA provides a segmented presentation of the individual vascular layers and plexuses, thus enabling previously unattainable differentiation and classification of pathological vascular changes within or underneath the retina. In particular, OCTA facilitates early detection of exudative macular neovascularizations (MNV) so that treatment with anti-VEGF medication can be initiated. Moreover, in the context of both screening and therapy monitoring, it is hoped that OCTA can provide more detailed data to enable greater personalization of treatment and follow-up. The image quality of OCTA is, however, susceptible to artifacts, and validation of the results by studies is required. Recent developments have shown constant improvement both in the algorithms for image calculation and avoidance of artifacts and in image quality, so the scope of OCTA will certainly expand with time.
