Background: The current treatment of Erectile Dysfunction (ED) is mainly based on the use of drugs that provide erections shortly after use but they do not really treat the problem. Stem cell therapy is a novel treatment with regenerative properties that can possibly treat erectile dysfunction. Methods: Five patients with erectile disease were treated with Adipose-Derived Stem Cells (ADSCs) and Platelet Lysate Plasma (PLP). ADSCs were obtained through abdominal liposuction and PLP was prepared after obtaining blood samples from peripheral veins. Erectile function was evaluated with the International Index of Erectile Function questionnaire (IIEF-5) questionnaire, penile triplex at the 1st, 3rd, 6th and 12th month post-treatment. A CT scan of the head, thorax and abdomen was done before treatment and at the 12th month. Results: IIEF-5 scores were improved in all patients at the 6th month although not in the same pattern in all patients. Peak Systolic Velocity (PSV) also improved at the 6th month in all patients but also with different patterns in each patient, while End Diastolic Velocity (EDV) was more variable. Two patients decreased the treatment they used in order to obtain erection (from Intracavernosal injections (ICI) they used PDE-5Is), two had unassisted erections and one had an initial improvement which decreased at the 6th month. There were no side effects noted. Conclusions: Stem cell therapy in combination with PLP appears to show some improvement in erectile function and has minimal side effects in the short term.

Erectile dysfunction (ED) affects more than 30 million men; endothelial dysfunction plays a significant role in EDs pathogenesis. The aim of this study was to administer mesenchymal stem cells (MSC) derived from adipose tissue and platelet lysate (PL) into patients with erectile dysfunction. This pilot study enrolled eight patients with diagnosed ED. Patients enrolled were suffering from organic ED due to diabetes melitus, hypertension, hypercholesterolaemia, and Peyronie disease. The patients were distributed in 2 groups. Patients in group A received adipose derived mesenchymal stem cells (ADMSC) resuspended in PL while patients in group B received only PL. ADMSCs were isolated from patients' adipose tissue and expanded. In addition, blood sampling was obtained from the patients in order to isolate platelet lysate. After the application of the above treatments, patients were evaluated with an International Index of Erectile Function (IIEF-5) questionnaire, penile triplex, and reported morning erections. After MSCs and PL administration, patients presented improved erectile function after 1 and 3 months of follow-up. A statistically significant difference was observed in the IIEF-5 score before and after administration of both treatments after the first month (p < 0.05) and the third month ( p < 0.05). No statistically significant difference was observed in the IIEF-5 score between group A and B patients. All patients were characterized by improved penile triplex and increased morning erections. No severe adverse reactions were observed in any patient except a minor pain at the site of injection, which was in the limits of tolerability. The results of this study indicated the satisfactory use of MSCs and PL in ED. MSCs in combination with PL or PL alone seems to be very promising, especially without having the negative effects of the current therapeutic treatment.

The non-recurrent laryngeal nerve (nRLN) is a rare anatomic variation that every head and neck surgeon must be aware of, in order to avoid intraoperative injury which leads to postoperative morbidity. We are reporting a case of a nRLN in a 47 year old female patient with medullary thyroid carcinoma who was surgically treated with total thyroidectomy and lymph node dissection. Both two inferior laryngeal nerves were identified, fully exposed and preserved along their cervical courses. However, we found that the right inferior laryngeal nerve was non-recurrent and directly arised from the cervical vagal trunk, entered the larynx after a short transverse course and parallel to the inferior thyroid artery. The safety of thyroid operations is dependent on high index of suspicion, meticulous identification and dissection of laryngeal nerves either recurrent or non-recurrent. This leads to minimum risk of iatrogenic damage of the nerves. Complete knowledge of the anatomy of these neural structures, including all their anatomic variations is of paramount importance.

Introduction: Wind instrumentalists require a sophisticated functioning of their respiratory system., Aim: The purpose of this research is to examine the function of the respiratory system of wind instrumentalists., Material and Methods: Thirty-two adult professional musicians from two philharmonic bands (Piraeus and Zografou Municipality) participated in the survey. Each participant, after completing a questionnaire given, went through two spirometric tests, one before and one after the rehearsal. The rehearsal lasted one hour and a half and included low-mid and high frequency notes. Respiratory volumes measured and analyzed were, vital capacity (VC), maximum expiratory volume of air in 1st second (FEV1), forced vital capacity (FVC), forced expiratory flow (FEF), and Tiffenau index (FEV1/FV%)., Results: The results showed that: 1) Participants did not show any noticeable change in their respiratory volumes before and after rehearsal. 2) Wind instrument players do not have a VC greater than their predicted age, height, weight and gender. 3) There is no statistically significant difference between the first and second assessment of respiratory indicators for smokers and non-smokers. 4) Regarding the type of instrument: a) Those who played wooden instruments improved the FEV1/FVC% indicator to a remarkable percentage between the first and second spirometry and b) individuals playing wooden instruments had a lower FVC, FEV1 and VC score than those playing bronze., Conclusion: There is no significant strain sign in respiratory system even in smokers after exercising in wind instrument. There is an improvement in Tiffenau index in those who played wooden instruments between the two rehearsals. Undoubtedly, new research is needed to combine a respiratory disease scenario with a respiratory treatment program that involves practicing a wind instrument.

The Authors report a complete study concerning complications, the imaging and functional results, the clinical outcome and the quality of life in patients treated with VIP. 95 patients with localized bladder TCC (T2N0M0) were evaluated. Follow up points were 1st, 3rd, 6th, 12th, 18th, 24th and 36th month with clinical and ultrasound evaluation. At 6th, 12th and 36th month CT pyelography and urodynamic evaluation were performed and we used a questionnaire for subjective bladder function and the EORTC QLQ C-30 questionnaire to evaluate quality of life. Perioperative complications were ileus (2 patients; 2.1%) (Clavien Grade IIIb), one postoperative death (1.0%) (Clavien Grade V) and a resuscitated cardiac arrest (1.0%) (Clavien Grade IVa). Postoperative complications were incisional hernias (n=4 patients; 4.21%) (Clavien Grade I) and hydronephrosis in five patients (5.26%) due to ureteric/neobladder stricture (Clavien Grade IIIb). Urine retention due to neobladder neck stenosis was observed in one patient (1.0%) (Clavien Grade IIIb) and an ileo-neobladder fistula in one (1.0%) patient (Clavien Grade IIIb). During follow up there were two cancer related deaths (2.1%). According to urodynamic evaluations neobladder capacity increased, end-filling pressure and Qmax decreased while residual urine and the number of intrinsic contractions remained stable. Continence rates and quality of life were high and stable during follow up. VIP technique for bladder substitution is a relatively easy technique with low rate of complications, good functional results which respect the patient's quality of life.

Lateral calcaneal flap is an established surgical option for coverage of lateral calcaneum and posterior heel defects. Lateral calcaneal flap vascularization and innervations are based on lateral calcaneal artery neurovascular bundle, that is, lateral calcaneal artery, small saphenous vein, and sural nerve. Anatomical research has allowed exploration of its many advantages but can also lead to its various modifications, permitting a wide variety of clinical applications. In this paper the authors report an anatomical and clinical study on lateral calcaneal artery course and lateral calcaneal flap clinical applications. Anatomic part of our study focused on lateral calcaneal artery course and optimization of surgical technique for flap harvesting. Data were used for design of lateral calcaneal flap in 5 patients. Our results were satisfactory in terms of coverage adequacy, perioperative morbidity, and functional and aesthetical outcome.

Background: Among the emerging treatments for erectile dysfunction (ED), platelet-rich plasma (PRP), known for its ability to enhance tissue repair and regeneration, stands out as a promising therapeutic approach. In this innovative study, we aimed to assess the efficacy of intracavernous injections of platelet lysate (PL), a derivative of PRP, in improving erectile function among ED patients. Methods: We enrolled twenty-six patients, aged between 35 and 70 years (mean age 51.6 ± 11.3 years), who had been experiencing ED for over six months and had an International Index of Erectile Function-5 (IIEF-5) score of 21 or less. Participants received autologous PL injections intracavernously every two weeks for a total of five administrations. We assessed Erection Hardness Score (EHS) and International Index of Erectile Function-5 (IIEF-5) bi-weekly for 16 weeks and conducted penile Doppler ultrasounds pre- and post-treatment to record peak systolic velocity (PSV) and resistance index (RI). Results: Before treatment, the mean EHS was 2.15 ± 0.88 and IIEF-5 was 10.92 ± 5.28. Remarkable improvements were observed post-treatment, with the EHS significantly increasing to 3.15 ± 0.83 (p < 0.05) and IIEF-5 to 17.23 ± 5.26 (p < 0.05). Penile Doppler ultrasound exhibited an increase in both PSV and RI post-treatment, with the rise in RI being statistically significant. Conclusions: Our findings indicate that intracavernous injections of PL substantially enhance erectile function, as evidenced by improvements in EHS, IIEF-5, and the RI of penile Doppler ultrasound, without hemorrhagic events or other adverse reactions apart from temporary pain at the injection site during the 16-week follow-up period. These encouraging results suggest that PL injections are a safe and effective treatment modality for patients with moderate ED, potentially providing a less invasive and more physiologically friendly alternative to current ED management strategies. Trial registration: The study received approval from the Institutional Review Board of National Taiwan University Hospital (IRB Number 202008061RIPC, date of registration 08/28/2020).

Background: According to the guidelines of the European Association of Urology, open simple prostatectomy should be offered to men with a prostate size exceeding 80 mL suffering from moderate to severe LUTS in the absence of a transurethral enucleation technique. However, open simple prostatectomy is associated with complications such as bleeding, blood transfusions and increased length of stay compared to minimally invasive procedures. The aim of the study was to compare perioperative data from the first cases of robotic assisted simple prostatectomy (RASP) to that of patients subjected to open simple prostatectomy (OSP) at our department. Methods: The patients were identified by a search for the respective procedure codes. In the OSP group enucleation of the adenoma was performed through the prostatic capsule (Millin procedure), while access to the adenoma was gained through the bladder in the RASP group. Complications were scored according to the Clavien-Dindo classification system. Results: 27 patients who underwent OSP were retrospectively identified and compared to the first 26 patients who were subjected to RASP. The groups were similar with respect to age, body mass index and ASA score. Operative time was significantly shorter in the OSP group compared to the RASP group. Bleeding volume, drop in postoperative hemoglobin and the number of blood transfusions were all significantly higher in the OSP group compared to the RASP group. Average length of stay was 5.5 (2–18) days in the OSP group compared to 1.6 (1–5) days in the RASP group (p < 0.001). The number of postoperative complications, Clavien-Dindo ≥ 2, were significantly higher in the OSP group (11) compared to the RASP group (none, p < 0.001). Conclusions: The introduction of robotic assisted simple prostatectomy reduced perioperative morbidity at our department. [ABSTRACT FROM AUTHOR]

Background: Recent studies have shown an association between playing wind instruments and their impact on the orofacial system. However, they have not fully evaluated all aspects of the topic, leaving a gap in the overall understanding. Methods: A thorough search of the National Library of Medicine database was conducted using our research strategy, resulting in the identification of relevant studies. An expert perspective was obtained by conducting two in-depth expert interviews with a professor of horn-playing and a specialised dentist. Results: Thirty-seven relevant publications were included in the traditional literature review. The most common diseases among professional wind instrumentalists include the lip area, temporomandibular joint, oral mucosa, respiratory system, oral allergic reactions, and orofacial trauma. Special measures, preventive measures, and expert opinions were utilised to address and overcome the associated orofacial problems. Conclusions: Wind instruments affect the oral health and tooth movement of professional instrumentalists, and dentists should consider the impact of dental changes on embouchure and performance. Dental impressions and three-dimensional intra-oral scans are important for reconstruction. This research highlights the need for specialised dental care for professional wind instrumentalists, and further studies are necessary to fully explore this topic. [ABSTRACT FROM AUTHOR]

Horseshoe kidney (HSK) is the most common renal fusion, which is characterized by three anatomic anomalies: ectopia, malrotation and vascular changes. Patients with HSK are prone to a variety of complications, genitourinary and non-genitourinary. In this paper, the anatomy of HSK is delineated with a great emphasis on its blood supply. After reviewing the literature, the arterial supply patterns found by each author were categorized according to the classification system proposed by Graves. The majority of HSKs were found to be supplied by renal arteries derived from the abdominal aorta below the isthmus or by vessels originating from the common iliac arteries. In addition, the abnormalities associated with HSK are highlighted and classified in anatomical variations, congenital anomalies as well as in pathologic conditions related to HSK.

Objective: To investigate the anatomical variability of the palatine structures in Greek population., Material and Methods: 71 Greek adult dry human skulls were examined to detect the position of the greater palatine (GPF) and lesser palatine foramina (LPF) related to adjacent anatomical landmarks., Results: The perpendicular distance of the GPF to the midline sagittal suture was 1.53 cm and 0.3 cm from the inner border of the alveolar ridge. The mean distance from the posterior palatal border was consistent 0.46 cm on the right and 0.47 cm on the left side of the skulls. In the greater majority of the skulls (76.2%), the GPF were between proximal-distal surfaces of the 3rd maxillary molar. A single LPF was observed in 53.45% of the skulls, two LPF were observed in 31% of the skulls bilaterally and five LPF were rare (2.1%). The commonest position of LPF was at the junction of the palatine bone and the inner lamella of the pterygoid plate (71.9%)., Conclusion: Our results can help clinicians localize the palatine foramina in patients with and without maxillary molars and to predict the depth of a needle to anaesthetise the maxillary nerve with greater success when performing surgical procedures in the hard and soft palate., (Copyright © 2011 European Association for Cranio-Maxillo-Facial Surgery.

The present study describes analytically a rare case in which lingual and facial arteries arise together from an external carotid artery in a common trunk. Thirty anatomic dissections were performed on 15 cadavers in the macroscopic laboratory in the Department of Anatomy of the Medical School of National and Kapodistrian University of Athens. One common trunk from which originated lingual and facial arteries was found. The frequency of this morphology is measured at 6 per cent. The length of the common trunk is measured at 7.3 mm between its origin and its diversion at the facial artery and lingual artery, its diameter at 2.8 mm, its distance from carotid bifurcation at 7.9 mm, and from the superior thyroid artery at 3.3 mm. At the left side of the neck region, facial and lingual arteries arose separately. The anatomic variations of the branching pattern of the external carotid artery and the micrometric values of the vessels are especially important as a result of the numerous operations performed in the neck region that implicate various specialties such as general surgery, head and neck surgery, plastic surgery, and maxillofacial surgery.

Aim: To present in human cadavers the anatomical basis of penis lengthening operations and reproduce this technique in a group of patients., Materials of Study: Penis ligaments in ten human cadavers were identified and dissected releasing the penis from its fixation to pubic arch. The same technique was applied to a group of forty patients that demanded a penis lengthening operation., Results: The dissection of penis ligaments increases the distance pubic bone-tip of the penis for 3.1 +/- 0.6 cm. In patients, the increase in length 12 months post-operatively was 3.5 +/- 1.3 cm (2.3-5.1 cm) flaccid and 1.8 +/- 1.4 cm (1.4-3.2 cm) erect. There was a statistically significant difference (p < 0.005) between preoperative and postoperative status. The overall satisfaction rate was 67.5%., Discussion: Cadavers study shows that this technique offers significant mobilization of the penis with a 3 cm gain, while on living tissue it has similar results. Anatomical parameters that might influence the final outcome of the operation are the length (antero-posterior dimension) of the pubic arch (corresponds to the length of the ligament), its angle with the horizontal level, the amount of the fatty tissue in the pubic area and the angle of the repositioning of the penis., Conclusions: Division of ligaments of the penis increases its apparent length. Significant anatomical parameters are the length of the pubic arch, its angle with the horizontal level, the amount of the fatty tissue in the pubic area and the angle of the repositioning of the penis.

Objectives: To assess the efficacy and the simplicity of a modified open transvesical prostatectomy for large prostates (>80 mL)., Methods: A total of 165 patients with benign prostatic hyperplasia were treated with transvesical prostatectomy through a 3-cm incision. Prostate size was 85-144 cm(3) (mean 101 cm(3)). Surgery is performed as the standard transvesical prostatectomy but skin incision is much smaller (approximately 3 cm), whereas muscle incision underneath is about 7 cm long. Prostate adenoma was removed with finger dissection without the placement of hemostatic sutures., Results: Operation time was 15-36 minutes (mean 24 minutes). Catheter was removed on the third day and patients left the hospital after successful voiding. Preoperative hematocrit was 40.6-49.2 (mean 43.4), while postoperative hematocrit was 28.3-42.4 (mean 38.3). Transfusion rate was 0-3 blood units (mean 1 U). Mean preoperative flow was 11.5 cm/s and mean postoperative flow was 22.3 cm/s. Mean IPSS score improve from 28 preoperatively to 15 postoperatively., Conclusions: Open transvesical prostatectomy with a 3-cm incision is a minimally invasive technique for the treatment of large prostates (>80 mL) in which transurethral prostatectomy or laser prostatectomy may not be the first choice., (2010 Elsevier Inc.

Objectives: This study aimed to evaluate the effectiveness of using indocyanine green (ICG) for assessing ureteral vascularity to reduce ureteral complications in patients undergoing extended hysterectomy for deep endometriosis or oncological indications. Methods: A retrospective-prospective cohort study was conducted at the Centre of Gynecology in Opole, Poland, involving 555 patients who underwent hysterectomy from 2020 to 2023. Patients were categorized based on the Querleu–Morrow classification. ICG was used intraoperatively for vascular assessment in patients with deep endometriosis undergoing wide ureter dissection typical of Type C hysterectomy. Results: Ureteral complications occurred in 12 (2.2%) patients, with a significantly lower complication rate in those who underwent ICG testing (1.7%) compared to those who did not (22.7%, p = 0.001). Prophylactic double-J stenting further reduced the risk of complications. Conclusions: The use of ICG for intraoperative assessment of ureteral vascularity significantly reduces the risk of ureteral complications in complex hysterectomies. Further studies are needed to confirm these findings. [ABSTRACT FROM AUTHOR]

During anatomical dissection of a female body donor at the Howard University College of Medicine, a rare renal anomaly was discovered. Detailed anatomical and histological analyses on this anomaly were compared to a normal kidney from another donor and previously published reports from a comprehensive literature review. Anatomical assessment confirmed the condition of pancake kidney, a rare form of completely fused, ectopic kidneys without an isthmus. Due to the lack of symptoms in patients with this condition and the limited number of published case reports, very little information is available regarding the anatomy, development, and histology of pancake kidneys, making it difficult to determine an accurate estimate of the number of individuals who are affected. In the case presented here, a single kidney was located in the pelvis, below the bifurcation of the abdominal aorta into the common iliac arteries. The histological analysis of the pancake kidney revealed focal segmental glomerulosclerosis, dilated renal tubules, and increased interstitial fluid, all common characteristics of renal disease and not present in the normal kidney of the other donor. Future studies are needed to compare the histology of pancake kidneys and typical kidneys in order to help determine potential pathologies. [ABSTRACT FROM AUTHOR]

Background. One of the common treatments for prostate cancer is radical prostatectomy, which is performed in different ways. One of the advantages of the nerve bundle preservation method is better exposure, decrease in rectal damage the lower rectum. In addition, the possibility of a positive margin is less. Therefore, this study aimed to examine the results of using the high anterior release (HAR) technique in radical open prostatectomy surgery. Methods. In this cross-sectional study, after examining patients and their entry into the study and obtaining their medical records, questions were asked to assess erectile function and urinary incontinence. The prostate-specific antigen level was checked before and after the operation. In addition, the average surgical time, blood loss, and hospitalization time were evaluated. Finally, the data were analyzed using the SPSS statistical analysis program, version 19. Results. In this study, 102 patients underwent radical prostatectomy, with an average age of 62.33 years. About 56.9% of patients had stage t2b. During the 6-month follow-up after surgery, 70.5% of patients had complete urinary continence. Data analysis demonstrated that there is a direct relationship between urinary incontinence, with a history of radiotherapy (P<0.001), and the stage of the disease (P=0.019). After surgery, 61.8% of patients were satisfied with the erection function . Conclusion. The results of this study revealed that urinary incontinence and erectile dysfunction are relatively common complications of this surgery. However, compared to other similar studies, the incidence of these two complications is lower. Practical Implications. Urinary incontinence and erectile dysfunction are relatively prevalent complications of radical prostatectomy surgery using the HAR technique. Nonetheless, the incidence of these two complications is lower compared to other similar studies. [ABSTRACT FROM AUTHOR]

Purpose: Neuroblastoma, the most common extracranial solid tumor in children under 5 years, often surrounds visceral arteries. This study aimed to analyze the working space provided by standardized surgical techniques at key arterial landmarks in adult cadavers. Methods: We assessed in eight adult cadavers the mobilization of the left colon, spleen and pancreas, right colon, duodenum and mesenteric root, access to the bursa omentalis. The average working space score (AWSS) was evaluated at the left and right renal artery, left and right side of the coeliac trunk, superior mesenteric and common hepatic artery. The score was defined as: (0) vessel not visible, (1) working space at the vessel ≤ 1x diameter of the aorta, (2) < 3x the diameter of the aorta, (3) ≥ 3x diameter of the aorta. Results: The maximum AWSS of 3 was achieved at key vascular landmarks through specific mobilization techniques. Conclusion: Additional mobilization of spleen, pancreas and mesenteric root and access to the bursa omentalis increase surgical working space at major visceral arteries. The results of our investigation provide surgeons with a useful guide to prepare for abdominal neuroblastoma resection. [ABSTRACT FROM AUTHOR]
