INTRODUCTION: Portal vein thrombosis (PVT) is a rare medical condition that obstructs blood flow in the portal vein, with cirrhosis as a common predisposing factor. However, its association with oral contraceptive pills (OCPs), particularly with progestins, remains inadequately explored. This case report aims to contribute to this understanding, focusing on the rare presentation of PVT-induced intestinal obstruction in a female on prolonged OCP therapy. CASE PRESENTATION: A 45-year-old female presented with severe abdominal pain, vomiting, and constipation...

INTRODUCTION: Despite the groundbreaking research by Judet and Letournel in the 1960s, the specific equipment, surgical approach, fixation strategy, and post-operative course for treating acetabular fractures have not been standardized. Therefore, this study aimed to compare technological resources, operative procedures, and post-operative complications between patients treated for acetabular fractures in Romania and the United States (U.S.). METHODS: Between February 2011 and August 2018, a total of 116 Romanian patients and 373 U...

OBJECTIVES: Recommendations on lithium dosing around delivery vary, with several guidelines suggesting that lithium should be discontinued prior to delivery. We aimed to evaluate the validity of these recommendations by investigating 1) maternal lithium blood level changes following delivery, and 2) the association between neonatal lithium blood levels at delivery and neonatal outcomes. METHODS: In this retrospective observational cohort study, we included women with at least one lithium blood level measurement during the final week of pregnancy and the first postpartum week...

Abnormalities in pulmonary vasculature or technical issues during lung procurement can lead to an insufficient left atrial (LA) cuff in donors. However, surgeons frequently need to reconfigure these less-than-ideal lungs for transplantation. This case report introduces a novel technique for such reconstruction. The patient was a 35-year-old male diagnosed with pneumoconiosis for over a year. Due to progressive worsening dyspnoea leading to respiratory failure on multiple occasions, he was deemed a candidate for lung transplantation...

BACKGROUND: Trigeminal neuralgia (TN) secondary to a dural arteriovenous fistula (DAVF) is quite rare, and the goal of treatment is to resolve both the fistula and the pain. CASE PRESENTATION: We herein report a case of TN secondary to a DAVF in a 64-year-old woman with a 1-year history of right-sided TN. Brain magnetic resonance imaging and digital subtraction angiography showed a right tentorial DAVF. Interventional embolization was performed, but the pain was not relieved after the operation...

INTRODUCTION: It has been previously proposed in numerous studies that chronic venous insufficiency (CVI) has similar pathogenesis to varicocele in males. Varicocele has been identified as the most common cause of infertility in men, accounting for 40% of cases. AIM: This study investigates whether varicocele screening should be conducted in patients with CVI and, if so, which patients should undergo such screening. MATERIAL AND METHODS: The study included 102 adult male patients with venous insufficiency complaints who presented to the cardiovascular surgery clinic between January 2023 and June 2023...

BACKGROUND: External iliac artery endofibrosis (EIAE) is an uncommon pathology, predominantly occurring in cyclists, caused by thickening of the external iliac artery intima. Symptoms are exercise-dependent and typically consist of pain, muscle cramps and loss of strength in the affected limb at (sub)maximal effort. As other musculo-skeletal as well as conditional problems might cause similar complaints diagnosis is not always easy or straightforward.Case summary and discussion: We reviewed four cases of (semi-)professional cyclists referred to our department in 2021 because of suspicion of EIAE ...

Von Hippel-Lindau (VHL) disease, an autosomal dominant genetic disorder caused by a germline mutation, is associated with non-functional and slow-growing pancreatic neuroendocrine tumor (PNET) and kidney cancer. We describe the case of a 46 year-old man with a 35 mm mass in the pancreatic head causing stricture of the bile duct and main pancreatic duct, a 55 mm mass in the pancreatic tail causing obstruction of the splenic vein (SV), and multiple masses of > 36 mm on both kidneys...

External nasal splints are commonly used for immobilization following nasal fracture reduction or rhinoplasty procedures. The literature documents the use of various materials like thermoplastic materials, aluminum, Orthoplast, fiberglass, plaster of Paris, and polyvinyl siloxane. These materials are bulky, time-consuming, expensive, and cumbersome to use, and have been associated with complications including contact dermatitis and epidermolysis. Furthermore, they cannot be retained if the situation warrants prolonged stabilization and immobilization...

OBJECTIVE: The aim of the study is to reveal the respiratory displacement of the right adrenal vein (RAV) to predict the exact location of the RAV during adrenal venous sampling (AVS). METHODS: Computed tomography (CT) scans obtained 45 seconds (breath-hold at inhalation) and 70 seconds (breath-hold at exhalation) after contrast material injection were compared to venograms of the RAV of patients with primary aldosteronism who underwent AVS between January 2016 and December 2020...

OBJECTIVE: We devised a split-bolus injection and imaging protocol for pulmonary artery and vein separation computed tomography (CT) angiography based on time enhancement curve characterization. Furthermore, we aimed to evaluate the contrast enhancement effect and success rate of blood vessel separation between the pulmonary artery and vein of this proposed protocol. METHODS: In this study, 102 patients (45 patients with the standard protocol and 57 patients with the proposed protocol) who underwent pulmonary arteriovenous computed tomography angiography were included...

Catheter ablation has become an accepted first line therapy for paroxysmal atrial fibrillation (PAF), with pulmonary vein isolation (PVI) being the key element of ablation strategies. Catheter ablation of AF has been proven to be superior to antiarrhythmic drug (AAD) therapy regarding efficacy and improvement of survival in patients with heart failure. PVI has become a routine treatment procedure in recent decades especially for patients with symptomatic PAF. Recent research investigations have shown that AF recurrence still occurs in a significant number of patients after ablation...

The continuous emergence of new psychoactive substances (NPS) attracted a great deal of attention within recent years. Lately, the two hallucinogenic NPS 1cP-LSD and 4-AcO-DET have appeared on the global market. Knowledge about their metabolism to identify potential metabolic targets for analysis and their cytotoxic properties is lacking. The aim of this work was thus to study their in vitro and in vivo metabolism in pooled human liver S9 fraction (pHLS9) and in zebrafish larvae (ZL) by means of liquid chromatography-high-resolution tandem mass spectrometry...

Deep vein thrombosis (DVT) represents a critical health concern due to its potential to lead to pulmonary embolism, a life-threatening complication. Early identification and prediction of DVT are crucial to prevent thromboembolic events and implement timely prophylactic measures in high-risk individuals. This study aims to examine the risk determinants associated with acute lower extremity DVT in hospitalized individuals. Additionally, it introduces an innovative approach by integrating Q-learning augmented colony predation search ant colony optimizer (QL-CPSACO) into the analysis...

Venous/arterial thrombosis poses significant threats to human health. However, drug-enabled thrombolysis treatment often encounters challenges such as a short half-life and low bioavailability. To address these issues, we report the design of erythrocyte-membrane (EM) camouflaged nanocapsules (USIO/UK@EM) incorporating ultra-small iron oxide (USIO) and urokinase (UK) drug, which exhibit remarkable photothermal/magnetothermal effects and drug delivery ability for venous and arterial thrombolysis. USIO, UK, and EM were coextruded to fabricate USIO/UK@EM with average sizes of 103...

This is a case involving a 3-year-old child who presented with an iatrogenic left subclavian/innominate vein lesion, leading to severe bleeding and intravascular catheter rupture during its removal. We successfully performed a very challenging and minimally invasive repair of the vein, along with the removal of the catheter entrapped in the innominate vein.

Significant progress in the investigation of how prior knowledge influences episodic memory has been made using three sometimes isolated (but not mutually exclusive) approaches: strictly adult behavioral investigations, computational models, and investigations into the development of the system. Here we point out that these approaches are complementary, each approach informs and is informed by the other. Thus, a natural next step for research is to combine all three approaches to further our understanding of the role of prior knowledge in episodic memory...
