Diagnosis of neuropathic pain (NP) can be challenging. The ID Pain (ID-P) questionnaire, a screening tool for NP, has been used widely both in the original version and translated forms. The aim of this study was to develop an Arabic version of ID-P and assess its validity and reliability in detecting neuropathic pain. The original ID-P was translated in Arabic language and administered to the study population. Reliability of the Arabic version was evaluated by percentage observed agreement, and Cohen's kappa; and validity by sensitivity, specificity, correctly classified, and receiver operating characteristic (ROC) curve...

BACKGROUND: Acne is very common skin condition. Most patients with acne will have a degree of scarring as a result of their acne. In patients with darker skin color the scarring can be further complicated by hyperpigmentation. Several treatment options can be used to improve acne scarring, however the problem of post acne hyperpigmentation is not often addressed. This study especially focus on the treatment of pigmented post acne scarring using skin microneedling. AIMS: The primary objective is to assess the improvement of pigmentation of acne scarring in patients with dark skin using microneedling...

PurposeThoracic aortic aneurysm/aortic dissection (TAAD) is a disorder with highly variable age of onset and phenotype. We sought to determine the prevalence of pathogenic variants in TAAD-associated genes in a mixed cohort of sporadic and familial TAAD patients and identify relevant genotype-phenotype relationships.MethodsWe used a targeted polymerase chain reaction and next-generation sequencing-based panel for genetic analysis of 15 TAAD-associated genes in 1,025 unrelated TAAD cases.ResultsWe identified 49 pathogenic or likely pathogenic (P/LP) variants in 47 cases (4...

A simple device, which is equipped with a non-woven fabric filter medium on which immobilized with ion-recognizable smart hollow microgels, is developed for facile detection of trace lead(II) ions (Pb2+). The ion-recognizable smart microgels are made of poly(N-isopropylacrylamide-co-benzo-18-crown-6-acrylamide) (PNB), in which the 18-crown-6 groups act as the sensors of Pb2+ and the N-isopropylacrylamide groups act as the actuators. The PNB hollow microgels can isothermally change from a shrunk state to a swollen state in response to recognizing Pb2+ in the aqueous environment due to the electrostatic repulsion among the charged 18-crown-6/Pb2+ complex groups and the enhancement of hydrophilicity of the microgels...

Selenium (Se)-containing molecules exert antioxidant properties and modulate targets associated with tumor growth, metastasis, angiogenesis, and drug resistance. Prevention clinical trials with low-dose supplementation of different types of Se molecules have yielded conflicting results. Utilizing several xenograft models, we earlier reported that the enhanced antitumor activity of various chemotherapeutic agents by selenomethione and Se-methylselenocysteine in several human tumor xenografts is highly dose- and schedule-dependent...

BACKGROUND: A significant proportion of cancer patients use complementary and alternative medicine (CAM) along with conventional therapies (CT), whereas a smaller proportion delay or defer CT in favor of CAM. Previous studies exploring CAM use among cancer patients in the Middle East region have shown discrepant results. This study investigates the prevalence and pattern of CAM use by Saudi cancer patients. It also discusses the possible benefits and harm related to CAM use by cancer patients, and it explores the beliefs patients hold and their transparency with health care providers regarding their CAM use...

Chronic HCV with its longstanding complications of cirrhosis and HCC is a highly prevalent and challenging problem in Egypt. Recently, microRNAs are ranked as potential biomarkers for early diagnosis of HCV related complications. The aim of the present study was to evaluate the role of miRNA-122 and miRNA-155 for prediction of progression of HCV infection and for diagnosis of HCC. A total of 92 chronic HCV patients [chronic HCV (group 1, n =32); chronic HCV with cirrhosis (group 2, n=31); chronic HCV with HCC (group 3, n=29)] were enrolled into the study...

Many apoptotic markers have been linked to hepatic cell injury in HCV-related liver diseases, and hence could be used as potential markers for early detection of the disease. The present study aimed to assess the role of apoptotic markers Bcl-2 and Bax in the pathogenesis of chronic HCV-related liver diseases. A total of 85 participants were enrolled into the study; 70 chronic HCV patients (35 non-cirrhotic and 35 cirrhotic), and 15 healthy controls. The serum levels of Bcl-2 and Bax were assayed in all participants by ELISA...

Male breast cancer is a rare malignancy that accounts for less than 1% of all cancers in men and less than 1% of all breast cancers. But the incidence is rising and in some patient groups reaching 15% over the course of their lives. The major risk factors for the development of male breast cancer include advancing age, hormonal imbalance, radiation exposure, and a family history of breast cancer. Regarding the latter, incidence can be linked to mutations in high- or low-penetrance genes. The most relevant risk factor for the development of male breast cancer is a mutation in the BRCA2 gene...

BACKGROUND: Total parenteral nutrition (TPN) is often used in children with perforated appendicitis, despite the absence of clear indications. We assessed the validity of specific clinical indications for initiation of TPN in this patient cohort. METHODS: Data were gathered prospectively on duration of nil per os (NPO) status and TPN use in a cohort of children treated under a perforated appendicitis protocol during a 19-month period. TPN was started in the immediate postoperative period in patients who had generalized peritonitis and severe intestinal dilatation at operation, or later per the discretion of the attending surgeon...

A convenient, fast and environmentally benign procedure for the synthesis of a new series of highly functionalized N -alkylated pyridines as privileged medicinal scaffolds was developed via a unique three-component reaction of easily available aromatic as well as heteroaromatic aldehydes, N -alkyl-2-cyanoacetamides and malononitrile in EtOH in the presence of K₂CO₃ as a base promoter under microwave irradiation. The presented tandem process is presumed to proceed via Knoevenagel condensation, Michael addition, intramolecular cyclization, autoxidation and subsequent aromatization...

Huntington disease (HD) is an inherited disorder hallmarked by progressive deterioration of specific neurons, followed by movement and cognitive anomalies. Cell therapy approaches in neurodegenerative conditions have concentrated on the replenishment of lost/dying neurons with functional ones. Multipotent mesenchymal stem cells (MSCs) have been represented as a potential remedy for HD. In this study, we evaluated the in vitro and in vivo efficacy of umbilical cord matrix stem cells (UCMSCs) and their paracrine effect against oxidative stress with a specific focus on HD...

Platelets have long been recognized as key players in hemostasis and thrombosis; however, growing evidence suggests that they are also significantly involved in cancer, the second leading cause of mortality worldwide. Preclinical and clinical studies showed that tumorigenesis and metastasis can be promoted by platelets through a wide variety of crosstalk between platelets and cancer cells. For example, cancer changes platelet behavior by directly inducing tumor-platelet aggregates, triggering platelet granule and extracellular vesicle release, altering platelet phenotype and platelet RNA profiles, and enhancing thrombopoiesis...

BACKGROUND: The orbitozygomatic approach is generally advocated over the pterional approach for basilar apex aneurysms. However, the impact of the extensions of the pterional approach on the obtained maneuverability over multiple vascular targets (relevant to basilar apex surgery) has not been studied before. OBJECTIVE: To analyze the patterns of surgical freedom change across the basilar bifurcation between the pterional, orbitopterional, and orbitozygomatic approaches...

Ventricular assist devices have become the standard therapy for end-stage heart failure. However, their use is still associated with severe adverse events related to the damage done to the blood by fluid dynamic stresses. This damage relates to both the stress magnitude and the length of time the blood is exposed to that stress. We created a dye washout technique which combines experimental and numerical approaches to measure the washout times of ventricular assist devices. The technique was used to investigate washout characteristics of three commercially available and clinically used ventricular assist devices: the CentriMag, HVAD and HeartMate II...
