Role of Point-of-Care Cerebral Ultrasonography in Determining the Etiology of Post-carotid Endarterectomy Deficit: A Case Report.

Carotid revascularization surgery is notorious for its neurological morbimortality. We report the case of a 74-year-old hypertensive patient, who underwent left internal carotid artery endarterectomy for a 90% stenosis under general anesthesia, presenting in the immediate postoperative period with right hemiplegia without consciousness disorders. Evaluation by cerebral ultrasound at bedside led to suspicion of intracerebral hemorrhage, which was confirmed by cerebral CT scan.

Second-order optimization strategies for neural network quantum states.

The Variational Monte Carlo (VMC) method has recently seen important advances through the use of neural network quantum states. While more and more sophisticated ansatze have been designed to tackle a wide variety of quantum many-body problems, modest progress has been made on the associated optimization algorithms. In this work, we revisit the Kronecker-Factored Approximate Curvature (KFAC), an optimizer that has been used extensively in a variety of simulations.

Product-specific reaction kinetics in continuous uniform supersonic flows probed by chirped-pulse microwave spectroscopy.

Experimental studies of the products of elementary gas-phase chemical reactions occurring at low temperatures (<50 K) are very scarce, but of importance for fundamental studies of reaction dynamics, comparisons with high-level quantum dynamical calculations, and, in particular, for providing data for the modeling of cold astrophysical environments, such as dense interstellar clouds, the atmospheres of the outer planets, and cometary comae. This study describes the construction and testing of a new apparatus designed to measure product branching fractions of elementary bimolecular gas-phase reactions at low temperatures. It combines chirped-pulse Fourier transform millimeter wave spectroscopy with continuous uniform supersonic flows and high repetition rate laser photolysis.

The quality monitoring of paracetamol medicament using a noninvasive microwave sensor.

Environmental conditions, including temperature, humidity, and light, can impact the quality of drugs. Microwave-based approaches offer a fast and cost-effective way to detect quality variations, providing an alternative to traditional techniques in the pharmaceutical and cosmetic industries. This article proposes the use of a microwave sensor for monitoring the quality of pharmaceutical drugs at distinct temperature levels.

Presentation of cryopyrin-associated periodic fever syndrome as chronic, afebrile urticaria in a 12-month-old female.

A healthy 12-month-old female presented with relapsing and remitting urticaria since birth that was resistant to treatment with antihistamines. A thorough history revealed extensive rheumatic disease on the father's side of the family, and subsequent genetic testing was positive for a missense variant of NLRP3, indicating cryopyrin-associated periodic fever syndrome (CAPS). CAPS encompasses a spectrum of diseases, all related to a defect in the same gene; manifestations vary in severity and presentation, but most are associated with recurrent rash and fever.

Primary amenorrhea secondary to imperforate hymen.

Hymen imperforation is uncommon. Symptoms include primary amenorrhea, cyclical lower abdominal pain, and rarely a pelvic mass syndrome. Delayed discovery may lead to endometriosis and infertility.

Sunscreen: a brief walk through history.

The sunscreens we see today were paved by our ancestors' sun protection methods, followed by scientific discovery in the more recent era and the trials and errors of the sunscreen formulations that followed. This history highlights sun protection methods used over the centuries and the varying degrees of agreeable sensorial properties or comforts in these methods.

Cutaneous Plasmacytosis and Idiopathic Multicentric Castleman Disease: A Spectrum of Disease?

Cutaneous/systemic plasmacytosis (C/SP) is a plasma cell disorder characterized by reddish-brown patches, lymphadenopathy, and hypergammaglobulinemia. The degree to which C/SP overlaps with other plasma cell proliferative disorders and neoplasms is incompletely understood. We present the case of a patient with a several-year history of cutaneous plasmacytosis and evidence of systemic involvement with concurrent idiopathic multicentric Castleman disease (iMCD) involving a lymph node.

Complex and CTX-M Extended-Spectrum β-Lactamases in Algeria.

We evaluated the β-lactam resistance phenotypes of clinical and environmental strains of the (ECC) isolated from three Algerian hospitals. The first combination of API 20E, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), and hsp60 genetic clustering methodologies were carried out for the identification of ECC strains. Our research showed that API 20E and MALDI TOF MS are satisfactory in genus identification of ECC strains, but sequence-based methods are then necessary to discriminate the species and subspecies levels.

Klatskin tumor presenting as unresectable perihilar hepatic mass: A case report.

Cholangiocarcinoma is a rare liver tumor with three types: intrahepatic, extrahepatic, and perihilar, which alone account for about 50% of cases. The diagnosis is late with a poor prognosis. Imaging through Bili MRI and CT scan plays an essential role in the classification and staging of tumors for therapeutic management.

Unexpected normal left ventricular systolic function after total chronic occlusion of left main coronary artery and stenosis of right coronary artery: a case report and review of the literature.

Introduction: Total occlusion of the left main coronary artery is a very rare finding in coronary angiography because of its highly lethal nature. Right coronary artery dominance and extensive collateral circulation are the principal determinant factors of survival after total occlusion of the left main coronary artery. The impact on the left ventricle is often significant with a profound alteration of its systolic function.

Early results for active infective endocarditis.

Introduction: Cardiac surgery is frequently needed during active phase of infective endocarditis (IE). The purpose of this study was to analyze the immediate and late results and determine the risk factors for death.

Methods: We retrospectively reviewed 101 patients with IE operated in the active phase.

A case of subarachnoid hemorrhage revealed by an acute coronary syndrome (ACS).

The subarachnoid hemorrhage (SAH) is definitely the best descriptive model of the interaction between cardiovascular system and cerebral damage. The underlying mechanism of cardiovascular alterations after SAH is linked to the adrenergic discharge related to aneurysm rupture. Cardiac and pulmonary complications are common after severe brain injury, especially the aneurismal subarachnoid hemorrhage.
