Evaluating tissue plasminogen activator (tPA) in dialysis catheter dysfunction: A focus on fibrin sheath and risk factors.

Background: Hemodialysis catheter dysfunction can arise from fibrin sheath formation, leading to impaired patency and compromised treatment. Tissue plasminogen activator (tPA) is an emerging treatment option to restore catheter patency. This study evaluated the efficacy of tPA therapy and explored clinical and demographic risk factors for catheter dysfunction.

Penetration of inferior vena cava (IVC) filter into abdominal aorta and repairing by Dacron patch arthroplasty: A case report.

Inferior vena cava (IVC) filters are ordinarily used to prevent pulmonary embolism (PE) in patients with contraindications to anticoagulation or those with an experience of bleeding after anticoagulation therapy. We present a 54-year-old female with a complex medical history, including diabetes mellitus, who developed acute deep vein thrombosis (DVT) after right common femoral vein (RCFV) catheter insertion, necessitating intravenous Heparin therapy. Anticoagulation was discontinued due to gastrointestinal bleeding, prompting inferior vena cava (IVC) filter insertion.

Multidisciplinary management of tracheal paraganglioma with angiographic embolization and surgical excision: A case report and review of literature.

Rationale: Tracheal paragangliomas (PGs) are exceedingly rare tumors originating from chromaffin cells. They often present with nonspecific symptoms like dyspnea and hemoptysis, which can mimic more common respiratory conditions such as asthma.

Patient Concerns: We present the case of a 58-year-old female initially diagnosed with asthma who later experienced recurrent hemoptysis and worsening dyspnea.

Case report: Endovascular treatment of transplant renal artery stenosis in patient with normal color duplex ultrasound of the renal artery.

Key Clinical Message: Proper diagnosis and treatment of vascular stenosis which is a possible complication of renal transplant is important in improving patients' quality of life and prognosis.

Abstract: One known consequence among recipients of renal transplants is graft renal artery stenosis. Early identification and therapy are crucial to avoid graft malfunction and the serious consequences that might arise due to elevated hypertension in several organs.

Obstructive jaundice as a rare complication of multiple pancreaticoduodenal artery aneurysms due to median arcuate ligament syndrome: a case report and review of the literature.

Background: Obstructive jaundice has various causes, and one of the rarest is pancreaticoduodenal artery aneurysm (PDAA), which is often associated with celiac axis stenosis caused by median arcuate ligament syndrome (MALS).

Case Presentation: The patient was a 77-year-old Azeri woman who presented with progressive jaundice, vague abdominal pain, and abdominal distension from 6 months ago. The intra- and extrahepatic bile ducts were dilated, the liver's margin was slightly irregular, and the echogenicity of the liver was mildly heterogeneous in the initial ultrasound exam.

Ultrasound-guided interventional approach to intraperitoneal nail gun injury: A case report with literature review.

Literature review suggests that surgery is the only option for dealing with intraperitoneal foreign bodies (laparoscopy and laparotomy). We showed that an interventional method using ultrasound guidance could be considered alongside surgical options.

Efficacy and safety of decompressive craniectomy in acute ischemic stroke patients treated with intravenous thrombolysis.

Introduction: The optimal timing for decompressive hemicraniectomy (DHC) after intravenous thrombolysis (IVT) remains unclear. This study in patients with acute ischemic stroke treated with IVT aimed to assess the safety of DHC and patient outcome.

Methods: Data was extracted from the Tabriz stroke registry from June 2011 up to September 2020.

Subtype distribution of lymphomas in northwestern Iran: a retrospective analysis of 659 cases according to World Health Organization classification.

Background: The distribution of lymphoma subtypes differs strikingly by geographic variations. However, there is limited information on this research in northern Iran. This study aims to evaluate the incidence, subtype, age, sex, and extranodal distribution of lymphomas diagnosed according to the latest WHO classification in a large referral center in northwest Iran.

Endovascular Treatment of the Ruptured Pseudoaneurysm of Common Femoral Artery in Behcet's Disease: Report of a Case with Four Years of Follow-Up.

Behcet's disease (BD) is a vasculitic condition that affects arteries and veins of all sizes. Arterial pseudoaneurysm is a rare but life-threatening complication of BD. We reported a 41-year-old man with 20 years history of BD and 5 years history of bilateral blindness.

Did COVID-19 impact stroke services? A multicenter study.

Background: It has been reported that acute stroke services were compromised during COVID-19 due to various pandemic-related issues. We aimed to investigate these changes by recruiting centers from different countries.

Methods: Eight countries participated in this cross-sectional, observational, retrospective study by providing data from their stroke data base.

The diagnostic value of susceptibility-weighted imaging for identifying acute intraarticular hemorrhages.

Purpose: To evaluate the diagnostic performance of susceptibility-weighted imaging (SWI) in identifying acute intraarticular hemorrhages and differentiating blood from other types of joint effusions.

Pentaorchidism diagnosed on ultrasound examination: A case report and literature review.

Polyorchidism is a congenital malformation of the urogenital system that is usually found incidentally in adolescent age groups. Ultrasound and MRI are effective non-invasive diagnostic modalities which can differentiate this condition from other intrascrotal pathologies. Ultrasonography is mostly used in initial steps of diagnostic approach; however, MRI is considered as a modality to confirm diagnosis and evaluate possible malignancy.

Melatonin: An atypical hormone with major functions in the regulation of angiogenesis.

Melatonin (N-acetyl-5-methoxytryptamine), a pleotropic molecule with a wide distribution, has received considerable attention in recent years, mostly because of its various major effects on tissues or cells since it has both receptor-dependent and receptor-independent actions over a wide range of concentrations. These biological and physiological functions of melatonin include regulation of circadian rhythms by modulating the expression of core oscillator genes, scavenging the reactive oxygen species and reactive nitrogen species, modulating the immune system and inflammatory response, and exerting cytoprotective and antiapoptotic effects. Given the multiple critical roles of melatonin, dysregulation of its production or any disruption in signaling through its receptors may have contributed in the development of a wide range of disorders including type 2 diabetes, aging, immune-mediated diseases, hypertension, and cancer.
