Coexistence of adenomyomatosis in a left-sided gallbladder: a case report.

Introduction: The coexistence of gallbladder (LSG) and adenomyomatosis (ADM) is extremely uncommon presenting a novel clinical dilemma that has not been previously documented. LSG refers to a anomaly where the gallbladder is situated to the left of the round ligament deviating from its usual position. This anomaly is rare, with reported occurrences ranging between 0.

Increased rate of anoxic brain damage with laryngeal tube compared to endotracheal intubation in patients with shockable out-of-hospital cardiac arrest - Experience from the HAnnover COoling REgistry (HACORE).

Background: Supraglottic airway devices such as the laryngeal tube (LT) are recommended in current guidelines for simplified airway management in patients during and immediately after out-of-hospital cardiac arrest (OHCA). Trials evaluating LTs included predominantly OHCA patients with non-shockable rhythms and low survival rates. Hence, LTs are widely used, but their impact on preventing hypoxic brain damage during resuscitation has not been evaluated yet.

Persistent Primitive Olfactory Artery Aneurysm.

A middle-aged adult presented to the hospital with a high-grade aneurysmal subarachnoid hemorrhage. The patient was treated with endovascular coil embolization of a ruptured basilar tip aneurysm. Angiography demonstrated multiple other aneurysms, including type I persistent primitive olfactory artery aneurysm.

Exercise Capacity, Iron Status, Body Composition, and Mediterranean Diet in Patients with Chronic Heart Failure.

In addition to drug therapy, lifestyle modification, including physical activity, and nutrition management are an integral part of current guidelines for patients with chronic heart failure (CHF). However, evidence on which clinical parameters are most influenced by nutritional behaviour, exercise capacity, or iron status is scarce. For a multicenter intervention study, we included participants with diagnosed CHF ( = 165) as well as participants with elevated NT-proBNP values and risk factors for CHF ( = 74).

Emergent carotid endarterectomy and mechanical thrombectomy in tandem occlusion.

Background: Acute tandem occlusions, or occlusions of the extracranial portion of the internal carotid artery (ICA) with concurrent thromboembolism of the intracranial ICA or middle cerebral artery, poses a major clinical challenge, with patients suffering worse outcomes compared to those with single occlusions. Management of these lesions generally includes a combination of mechanical thrombectomy (MT) of the intracranial occlusion and stenting of the extracranial carotid lesion. In this manuscript, we describe a successful surgical method for achieving revascularization of tandem occlusions in the rare circumstance that the proximal lesion cannot be crossed endovascularly to gain intracranial access.

Additive Impact of Interleukin 6 and Neuron Specific Enolase for Prognosis in Patients With Out-of-Hospital Cardiac Arrest - Experience From the HAnnover COoling REgistry.

Background: Patients after out-of-hospital cardiac arrest (OHCA) are at increased risk for mortality and poor neurological outcome. We assessed the additive impact of interleukin 6 (IL-6) at admission to neuron-specific enolase (NSE) at day 3 for prognosis of 30-day mortality and long-term neurological outcome in OHCA patients.

Methods: A total of 217 patients from the HAnnover COoling REgistry with return of spontaneous circulation (ROSC) after OHCA and IL-6 measurement immediately after admission during 2017-2020 were included to investigate the prognostic value and importance of IL-6 in addition to NSE obtained on day 3.

Cervical carotid occlusion in acute ischemic stroke: Should we give tPA?

Background: Acute ischemic stroke (AIS) due to cervical internal carotid artery (cICA) occlusion is challenging to treat, with the lower revascularization rates, higher risk for complications, and poor response to thrombolytic therapy compared to isolated intracranial occlusions. While emergent revascularization through mechanical thrombectomy (MT) improves outcomes, the impact of tissue plasminogen activator (tPA) on outcomes in this subgroup of patients remains unclear. The objective of this study is to report our preliminary experience in treating AIS with cICA occlusions secondary to severe atherosclerotic stenosis and to establish the need for further clinical studies to determine the optimal intervention strategy for these lesions.

Computed-Tomography as First-line Diagnostic Procedure in Patients With Out-of-Hospital Cardiac Arrest.

Background: Mortality after out-of-hospital cardiac arrest (OHCA) with return of spontaneous circulation (ROSC) remains high despite numerous efforts to improve outcome. For patients with suspected coronary cause of arrest, coronary angiography is crucial. However, there are other causes and potentially life-threatening injuries related to cardiopulmonary resuscitation (CPR), which can be detected by routine computed tomography (CT).

Aneurysmal subarachnoid hemorrhage, a presentation of metastatic carcinoma: A case report and review of the literature.

Background: Neoplastic cerebral aneurysms related to metastatic processes are exceptionally rare and carry a dismal prognosis. Only four previous reports exist of neoplastic aneurysms secondary to metastatic adenocarcinoma, all of which were found to be lung cancer in origin. We present the fifth reported metastatic adenocarcinomatous cerebral aneurysm, and the first case is secondary to a non-lung cancer primary.

High rate of critical coronary stenosis in comatose patients with Non-ST-elevation out-of-hospital cardiac arrest (NSTE-OHCA) undergoing therapeutic hypothermia-Experience from the HAnnover COoling REgistry (HACORE).

Background: Myocardial infarction is the most frequent cause for out-of-hospital cardiac arrest (OHCA) in adults. Patients with ST-segment elevations (STE) following return of spontaneous circulation (ROSC) are regularly admitted to the catheterisation laboratory for urgent coronary angiography. Whether patients without obvious STE (NSTE) should receive coronary angiography as part of a standardised diagnostic work-up following OHCA is still debated.

Neuromarkers and neurological outcome in out-of-hospital cardiac arrest patients treated with therapeutic hypothermia-experience from the HAnnover COoling REgistry (HACORE).

Background: Neuron-specific enolase (NSE) and S-100b have been used to assess neurological damage following out-of-hospital cardiac arrest (OHCA). Cut-offs were derived from small normothermic cohorts. Whether similar cut-offs apply to patients treated with hypothermia remained undetermined.

[Eosinophilic Granulomatosis with Polyangiitis with Pulmonary and Cardiac Involvement].

A 62-year-old patient with bronchial asthma and chronic rhinosinusitis underwent inguinal hernia surgery. After the operation, sudden circulatory arrest occurred, requiring cardiopulmonary resuscitation. Coronary angiography revealed a 99 % proximal stenosis of right coronary artery (RCA) with unsuspicious and smooth coronary vessel walls.

Iatrogenic cortical pseudoaneurysm following ventriculoperitoneal shunt insertion presenting with intraventricular hemorrhage.

Background: Cerebral pseudoaneurysm formation associated with ventricular catheterization is an exceedingly rare complication that results from direct catheter-induced injury to a vessel. We report a case of intracerebral pseudoaneurysm formation associated with ventricular catheterization in a patient with hydrocephalus following aneurysmal subarachnoid hemorrhage.

Case Description: The patient presented with aneurysmal subarachnoid hemorrhage and underwent partial endovascular embolization of the offending wide-necked basilar tip aneurysm with the plan for a Stage 2 stent-assisted coiling after initial recovery.

Squatting versus squatting with hip adduction in management of patellofemoral osteoarthritis: A randomized controlled trial.

Background: Patellofemoral osteoarthritis is a common presentation in the outpatients' physical therapy clinics. The muscle imbalance between the vastus medialis oblique and vastus lateralis muscles is one of the main factors that lead to the development of this condition.

Objective: To compare the effect of a squatting versus squatting with hip adduction in management of patellofemoral osteoarthritis.

True Cortical Saccular Aneurysm Presenting as an Acute Subdural Hematoma.

Background: Subdural hematoma, without any radiographic evidence of subarachnoid hemorrhage, is a rare presentation of a ruptured intracranial aneurysm. Even more rare is the occurrence of a pure subdural hematoma caused by a ruptured cortical saccular aneurysm. We report the eighth case of pure subdural hematoma secondary to a ruptured nonmycotic cortical berry aneurysm.

Clival Ectopic Pituitary Adenoma Mimicking a Chordoma: Case Report and Review of the Literature.

Development of venous thromboembolism (VTE) in patients undergoing surgery for brain tumors: results from a single center over a 10 year period.

Patients who undergo craniotomy for brain neoplasms have a high risk of developing venous thromboembolism (VTE), including deep vein thromboses (DVT) and pulmonary emboli (PE). The reasons for this correlation are not fully understood. This retrospective, single-center review aimed to determine the risk factors for VTE in patients who underwent neurosurgical resection of brain tumors at Northwestern University from 1999 to 2010.

Early postmarket experience after US Food and Drug Administration approval with the Trevo device for thrombectomy for acute ischemic stroke.

Background: TREVO 2 showed the Trevo stent retriever to be more successful for revascularization than Merci for acute stroke intervention in patients treated within 8 hours of symptom onset. These results led to US Food and Drug Administration approval of Trevo.

Objective: To report the first postmarket experience with Trevo since US Food and Drug Administration approval at a single high-volume comprehensive stroke center in the United States.

Venous thromboembolism in high grade glioma among surgical patients: results from a single center over a 10 year period.

Patients with high-grade glioma are at elevated risk of venous thromboembolism (VTE). The relationship between VTE and survival in glioma patients remains unclear, as does the optimal protocol for chemoprophylaxis. The purpose of this study was to assessthe incidence of and risk factors associated with VTE in patients with high-grade glioma, and the correlation between VTE and survival in this population.

New-generation oral anticoagulants for the prevention of stroke: implications for neurosurgery.

A new generation of oral anticoagulants, namely direct thrombin inhibitors and factor Xa inhibitors, have recently been approved for clinical use in patients with atrial fibrillation. These novel families of drugs have been shown to have favorable efficacy and safety profiles in multiple clinical settings, particularly in the prevention of atrial fibrillation-related stroke, and are likely to become part of everyday practice, making a crossover to neurosurgical patients inevitable. Concern has risen regarding the complexity of managing intracranial and intraspinal hemorrhages related to these drugs.
