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.

Advancements in the Management of Postoperative Air Leak following Thoracic Surgery: From Traditional Practices to Innovative Therapies.

Background: Postoperative air leak (PAL) is a frequent and potentially serious complication following thoracic surgery, characterized by the persistent escape of air from the lung into the pleural space. It is associated with extended hospitalizations, increased morbidity, and elevated healthcare costs. Understanding the mechanisms, risk factors, and effective management strategies for PAL is crucial in improving surgical outcomes. Aim: This review seeks to synthesize all known data concerning PAL, including its etiology, risk factors, diagnostic approaches, and the range of available treatments from conservative measures to surgical interventions, with a special focus on the use of autologous plasma. Materials and Methods: A comprehensive literature search of databases such as PubMed, Cochrane Library, and Google Scholar was conducted for studies and reviews published on PAL following thoracic surgery. The selection criteria aimed to include articles that provided insights into the incidence, mechanisms, risk assessment, diagnostic methods, and treatment options for PAL. Special attention was given to studies detailing the use of autologous plasma in managing this complication. Results: PAL is influenced by a variety of patient-related, surgical, and perioperative factors. Diagnosis primarily relies on clinical observation and imaging, with severity assessments guiding management decisions. Conservative treatments, including chest tube management and physiotherapy, serve as the initial approach, while persistent leaks may necessitate surgical intervention. Autologous plasma has emerged as a promising treatment, offering a novel mechanism for enhancing pleural healing and reducing air leak duration, although evidence is still evolving. Conclusions: Effective management of PAL requires a multifaceted approach tailored to the individual patient's needs and the specifics of their condition. Beyond the traditional treatment approaches, innovative treatment modalities offer the potential to improve outcomes for patients experiencing PAL after thoracic surgery. Further research is needed to optimize treatment protocols and integrate new therapies into clinical practice.

Bronchial stump insufficiency (BSI), also reported as bronchopleural fistula, following pneumonectomy is a rare but potentially devastating complication that can result in substantial morbidity and mortality. Despite advances in thoracic surgical techniques and perioperative care, bronchial stump dehiscence remains a challenging clinical scenario, especially when associated with severe infections and compromised patient conditions. Traditional surgical re-intervention to address this complication may carry significant risks and might be contraindicated in certain patients. As a result, innovative interventions are necessary to address these challenging cases effectively. In this report, we present an interventional endoscopic technique using an Amplatzer Duct occluder for the successful management of BSI in a 55-year-old male patient with a complex medical history.

A Rare Case of Spontaneous Pneumothorax Recurrence 30 Years After Surgery in a Patient with Birt-Hogg-Dube Syndrome: Case Presentation and Short Review of the Literature.

Background: Birt-Hogg-Dube syndrome (BHDS), also known as Hornstein-Knickenberg syndrome is a rare, autosomal dominant genetic disorder characterized by a triad of clinical manifestations: skin fibrofolliculomas, renal tumors, and multiple pulmonary cysts. The exact incidence of BHDS syndrome is unknown. This hereditary syndrome is caused by mutations in the folliculin (FLCN) gene, located on chromosome 17p11.2, which encodes the folliculin protein. Objective: This case report aims to highlight the importance of increased vigilance and long-term follow-up in BHDS patients, even decades after surgical intervention, to detect and manage potential pulmonary complications effectively. Case presentation: We present a unique case of spontaneous pneumothorax recurrence in a 63-year-old patient with a history of Birt-Hogg-Dube syndrome. The patient had undergone surgical treatment for pneumothorax 30 years ago and remained asymptomatic until presenting to our clinic with acute dyspnea and a dry cough. A recurrent pneumothorax was diagnosed and treated with a chest tube. Further chest imaging revealed extensive ground-glass opacities and cysts in both lungs. The patient was diagnosed with active pneumonia. A conservative approach was adopted due to the pneumonia diagnosis, and the patient showed a successful recovery without pneumothorax recurrence. Conclusion: This case highlights the importance of long-term follow-up in patients with Birt-Hogg-Dube syndrome and previous pneumothorax episodes.

The Perioperative Use of Levosimendan as a Means of Optimizing the Surgical Outcome in Patients with Severe Heart Insufficiency Undergoing Cardiac Surgery.

BACKGROUND: Postoperative myocardial dysfunction following cardiac surgery is a relatively common occurrence. Levosimendan, a calcium sensitizer and inotropic drug, has shown potential in improving outcomes for patients with low preoperative ejection fraction (EF) and myocardial dysfunction after cardiac surgery. This study aims to evaluate the efficacy of levosimendan in optimizing the surgical outcome for such patients. METHODS: A retrospective analysis was conducted on 314 patients with preoperative severe heart failure who underwent cardiac surgery. Among them, 184 patients received perioperative adjunctive therapy with levosimendan, while a comparable group of 130 patients received conventional treatment. RESULTS: The use of levosimendan demonstrated several advantages in postoperative outcomes. It significantly improved short- and long-term survival rates after cardiac surgery, enhanced hemodynamic stability, reduced the requirement for inotropic support, and facilitated faster weaning from ventilator support. Patients who received levosimendan reported reduced angina and dyspnea symptoms, as well as fewer postoperative arrhythmias. Furthermore, levosimendan helped minimize myocardial injury inevitable after cardiac surgery. The levosimendan group also exhibited a notable reduction in hospital readmissions. CONCLUSIONS: This study provides evidence of several benefits associated with the perioperative use of levosimendan. However, further prospective randomized studies are warranted to standardize and comprehensively document the other perioperative therapies, in order to validate these findings and establish stronger conclusions.

Obturator Hernia in a 71-Year-Old Patient: A Diagnostic Challenge.

An obturator hernia is a relatively rare form of pelvic hernia, wherein abdominal organs protrude through an opening in the pelvis known as the obturator foramen. The majority of patients with this condition present to the emergency room with symptoms of bowel obstruction. Due to the non-specific nature of these symptoms, making a preoperative diagnosis of obturator hernia can be challenging. Any delay in the diagnosis and treatment of this condition can lead to a significant risk of mortality. In this report, we present the case of a 71-year-old patient who presented to the emergency department complaining of lower abdominal pain and nausea. An abdominal X-ray revealed bowel dilation, and based on the patient's symptoms, a diagnosis of bowel obstruction was suspected. A CT scan of the abdomen and pelvis was performed to investigate the reason for bowel dilation, and the existence of an obturator hernia was confirmed.

Lung cancer invading the superior vena cava - surgical treatment. A short and up-to-date review.

Lung cancer is one of the leading causes of cancer-related deaths worldwide. Superior vena cava syndrome (SVCS) is a rare but potentially life-threatening complication of lung cancer, occurring in approximately 5-10% of cases. There are difficulties in the process of surgical treatment of SVC infiltrated by lung tumors but the contribution of technological evolution and innovation is promising. At the same time, the amelioration of survival rates of patients subjected to surgical treatment is equally promising. The reported outcomes of surgical treatment for SVC invasion due to lung tumors vary depending on the extent of the tumor and the patient's overall health status. However, studies clearly suggest that surgical treatment can improve survival and quality of life in selected patients. The literature review showed that the surgical approach to lung cancer invading the SVC constitutes the most indispensable treatment which helps to achieve the long-term survival of patients.

Perioperative Application of Levosimendan Optimizes Postoperative Renal Function and Organ Perfusion in Patients with Severe Heart Failure.

Background: Renal dysfunction and impaired organ perfusion are common concerns following cardiac surgery. Levosimendan, a calcium sensitizer inotropic drug, is investigated in this study for its potential to improve postoperative renal function and organ perfusion in patients with low preoperative ejection fraction and severe myocardial dysfunction after cardiac surgery. Methods: A retrospective analysis was conducted on 314 patients with preoperative heart failure who underwent cardiac surgery. Among them, 184 patients received perioperative adjunctive therapy with levosimendan, while 130 patients with similar characteristics received conventional treatment. Results: The perioperative administration of levosimendan resulted in a significantly lower need for renal replacement therapy (p < 0.001) and improvements in the serum creatinine levels, glomerular filtration rate, and creatinine clearance. Similarly, the C-reactive protein levels, blood pH, and lactic acid levels showed comparable improvements. Conclusions: The use of levosimendan was associated with a significant enhancement in postoperative renal function and a reduction in the need for renal replacement therapy. Furthermore, it resulted in a decrease in the extent of organ malperfusion. Postoperative inflammatory reactions and metabolic balance also exhibited improvements.

Right-Sided Diverticulitis: A Rare Cause of Right-Sided Abdominal Pain.

Acute diverticulitis is a particularly common medical entity, and its frequency increases with age. The most commonly affected part of the large intestine is the sigmoid colon, while right-sided diverticulitis is very rare. Here, we report the case of a 59-year-old man who presented to the emergency department due to acute right lower quadrant abdominal pain. The patient was diagnosed with a computed tomography scan of the abdomen with intravenous contrast with right-sided diverticulitis. The patient's treatment included hydration and intravenous antibiotics (ciprofloxacin and metronidazole). After three days of hospitalization, the patient was discharged from the hospital in stable condition and without signs of inflammation. This case report demonstrates the importance of including right-sided diverticulitis in the differential diagnosis of acute right lower quadrant abdominal pain, as in most cases patients are treated conservatively without the need for surgical intervention.

Surgical Repair of Spontaneous Lung Herniation Induced by Vigorous Coughing: A Case Report and Literature Review.

Lung herniation is a rare clinical entity defined by extrathoracic protrusion of the lung or lung tissue due to a weakness in the thoracic wall. We present here a case of a 72-year-old male who presented with a spontaneous lung herniation, which occurred as a result of a ventral luxation of the third rib from the sternocostal joint due to vigorous coughing. The defect was repaired through anterolateral thoracotomy, reposition of the lung and approximating the ribs using heavy sutures. The postoperative course of the patient was uncomplicated. A brief review of the literature is also provided.

Femoral Hernia Containing a Strangulated Appendix: A Hybrid Approach.

We present an intriguing case of an incarcerated femoral hernia containing an inflamed appendix inside the sac, also known as a De Garengeot hernia. This type of hernia is a rare occurrence that was first described in 1731 by the French surgeon René-Jacque Croissant de Garengeot. A 64-year-old woman presented to the emergency department with a painful mass in the right groin region. Following a computed tomography (CT) scan of the abdomen and pelvis to evaluate the mass, the diagnosis of a femoral hernia containing a strangulated appendix was established. Subsequently, a hybrid surgical approach was utilized, consisting of an open hernia repair and a laparoscopic appendectomy.
