Investigation of Machine and Deep Learning Techniques to Detect HPV Status.

BACKGROUND: This study investigated alternative, non-invasive methods for human papillomavirus (HPV) detection in head and neck cancers (HNCs). We compared two approaches: analyzing computed tomography (CT) scans with a Deep Learning (DL) model and using radiomic features extracted from CT images with machine learning (ML) models. METHODS: Fifty patients with histologically confirmed HNC were included. We first trained a modified ResNet-18 DL model on CT data to predict HPV status. Next, radiomic features were extracted from manually segmented regions of interest near the oropharynx and used to train four ML models (K-Nearest Neighbors, logistic regression, decision tree, random forest) for the same purpose. RESULTS: The CT-based model achieved the highest accuracy (90%) in classifying HPV status. Among the ML models, K-Nearest Neighbors performed best (80% accuracy). Weighted Ensemble methods combining the CT-based model with each ML model resulted in moderate accuracy improvements (70-90%). CONCLUSIONS: Our findings suggest that CT scans analyzed by DL models hold promise for non-invasive HPV detection in HNC. Radiomic features, while less accurate in this study, offer a complementary approach. Future research should explore larger datasets and investigate the potential of combining DL and radiomic techniques.

Addressing recurrent hypoglycaemia through thoracic surgical intervention: understanding Doege-Potter syndrome, a rarity in syndromes.

Doege-Potter syndrome (DPS), a rare paraneoplastic phenomenon characterised by non-islet cell tumour hypoglycaemia (NICTH), presents clinicians with intricate diagnostic and therapeutic challenges. This comprehensive review consolidates current understanding, clinical presentations, diagnostic modalities, therapeutic interventions, and emerging trends in managing DPS. The pathophysiology of DPS revolves around dysregulated insulin-like growth factors (IGF), particularly IGF-2, produced by mesenchymal tumours, notably solitary fibrous tumours (SFT). Clinical manifestations encompass recurrent hypoglycaemic episodes, often distinct from typical hypoglycaemia, with implications for insulin and counterregulatory hormone levels. Diagnosis necessitates a multidisciplinary approach integrating biochemical assays, imaging studies, and histopathological confirmation of the underlying neoplasm. Surgical resection remains the cornerstone of treatment, complemented by adjunctive therapies to manage persistent hypoglycaemia. Prognosis is influenced by successful tumour resection and long-term surveillance for recurrence. A patient-centred approach, incorporating supportive services and multidisciplinary care, is essential for optimal outcomes in individuals affected by DPS.

Secondary aortoenteric fistula: a narrative review of the view of the surgeon.

Aortoenteric fistula (AEF) is defined as the abnormal communication between the aorta and the gastrointestinal tract. AEFs are divided into primary and secondary usually after abdominal aortic aneurysm (AAA) recovery and are a rare but quite dangerous cause of gastrointestinal bleeding that the general surgeon may face during his/her career. Secondary AEF was first described in 1953 to a 44-year-old woman 3 months after an AAA operation. This review presents the role of the surgeon in the management of secondary aortoenteric fistulas. AEFs are a rare but fatal gastrointestinal bleeding cause that the general surgeon may be asked to manage. Diagnosis requires the combination of strong clinical suspicion and the presence of a history of AAA surgery. Although a vascular surgery case, general surgeons play a role in choosing the technique of restoring the intestinal tract, which seems to be significantly related to subsequent morbidity and mortality.

Demographic and clinical characteristics of patients with varicose veins in Albania: a retrospective, single-centre analysis.

Introduction: Chronic venous disease (CVD) constitutes a frequently underdiagnosed pathological condition that progressively diminishes patients' quality of life and imposes an escalating strain on healthcare resources. This study aims to comprehensively investigate the epidemiological landscape of varicose vein disease, examining age group distributions, gender patterns, residence influences, marital status correlations, weight considerations, educational impacts, and various aspects related to varicose veins. Material and methods: This was a single-centre retrospective analysis, in Albania from May 2018 to September 2023. Data were collected retrospectively through hospital records. Data collection involved administering a structured questionnaire to study participants, categorically organised into three sections. The first section focused on collecting demographic information, the second section involved self-perception of identifying risk factors associated with varicose veins, and the final section included inquiries about the history of variceal surgery. Results: The CEAP classification distribution in our cohort revealed a predominant presence of C2 (varicose veins) in 53.3% of patients, followed by C3 (oedema) at 29.2%, and C4 (changes in skin and subcutaneous tissue secondary to CVD) at 10.5%, whereas C5 (healed venous ulcer) and C6 (active venous ulcer) were less frequent. Based on the body mass index (BMI) scale, data from patients indicated that 9.7% were in the category of underweight, 54.8% had a normal BMI, and 35.5% were categorised as overweight. Conclusions: The study's thorough exploration of patient perspectives, risk factors, and treatment choices contributes to a holistic understanding of varicose vein management, emphasising the importance of personalised approaches that account for demographic variations and individual beliefs.

Challenges and pitfalls in the perioperative management of mediastinal mass syndrome: an up-to-date review.

The perioperative management of patients undergoing mediastinal mass operations presents a persistent challenge across multiple clinical specialties. General anesthesia administration further increases the risk of perioperative cardiorespiratory decompensation. The interdisciplinary team plays a crucial role in ensuring a safe perioperative period. However, due to the rarity and variability of mediastinal mass syndromes, specific management protocols are lacking. This review aims to outline the multitude of challenges and pitfalls encountered during perioperative management in patients with the mediastinal mass syndrome. We describe diagnostic evaluation, preoperative optimization, intraoperative considerations, and postoperative care strategies, emphasizing the paramount significance of a multidisciplinary approach and personalized treatment plans. Preoperative multidisciplinary discussions, meticulous anesthetic management, and well-established protocols for emergency situations are pivotal to ensuring patient safety. Healthcare providers involved in the care of patients with mediastinal mass syndrome must grasp these challenges and pitfalls, enabling them to deliver safe and effective perioperative management.

Salvage laparoscopic extraperitoneal radical prostatectomy after failed high-intensity focused ultrasound and radiotherapy for localized prostate cancer.

OBJECTIVES: To investigate the feasibility and efficacy of salvage endoscopic extraperitoneal radical prostatectomy (EERPE) in cases of recurrent prostate cancer after high-intensity focused ultrasound therapy (HIFU) or radiotherapy. METHODS: Nine patients underwent salvage EERPE with curative intent for biopsy-proven, locally recurrent prostate cancer. Of these 9 patients, 3 had previously undergone HIFU and 6 radiotherapy. Perioperative parameters (operation time, estimated blood loss, conversion to open surgery rate, transfusion rate, transurethral catheter time), functional outcome, and short-term oncologic outcome were reviewed. RESULTS: Mean patient age was 63.3 years (range 48 to 74 years). Mean preoperative PSA value was 12.64 ng/mL and mean prostate weight was 49.2 g. Mean blood loss was 238 mL. There was no need for conversion to open surgery or transfusion. Mean operation time was 148 minutes, and mean total transurethral catheter time was 6 days. No intraoperative complications were reported. There was no clear difference in operation difficulty between the post-HIFU and postradiotherapy EERPE. After a mean follow-up of 17 months, 7 patients were completely continent, and 2 needed 1 to 2 pads per day. Three patients were potent before the surgical treatment, but no patient reported potency postoperatively. In 1 patient a PSA relapse (1.20 ng/mL) was recognized 12 months postoperatively. CONCLUSIONS: Salvage EERPE after failed HIFU and radiation therapy is a safe and efficient method to treat locally recurrent prostate cancer. Short-term oncologic and functional outcomes are promising, but further study should be made on the long-term oncologic outcomes of this technique.

Role of laparoscopy for reconstructive urology.

PURPOSE OF REVIEW: Laparoscopic reconstructive urology is a challenging and technically demanding field of urology. As urologists' experience strengthened and technical modifications developed, urologic laparoscopy was applied in the treatment of malignancies and evolved from simple to technically demanding reconstructive techniques. This article reviews the latest published literature in the field of laparoscopic reconstructive urology and introduces our own persuasion for the role of this approach in urology. RECENT FINDINGS: Some laparoscopic procedures like orchidopexy, ureterolithotomy, pyelolithotomy and pyeloplasty require "a middle class level of laparoscopic skills" whereas other reconstructive techniques such as radical prostatectomy and cystectomy and partial nephrectomy are technically demanding and are still being developed with promising results. The reconstructive part of partial nephrectomy is small and refers to good hemostasis whereas in radical prostatectomy and cystectomy, the reconstructive part--urethrovesical anastomosis and urinary diversion, respectively--is an important factor, affecting the patient's postoperative quality of life. SUMMARY: The development of new instrumentation as well as the amelioration of urologists' laparoscopic skills will pave the way for the establishment of laparoscopic reconstructive urology in everyday practice. So far, laparoscopic reconstructive urology seems to be a well tolerated and effective treatment modality but still with not a completely clear role.
