No full textOssification of the yellow ligament in the cervical spine – an unusual location
No full textOssification of the yellow ligament (OYL) or ligamentum flavum, usually occurs in the thoracic spine. Focal OYL occurring in the cervical spine is considered rare and is sparsely reported in the literature. We came across a 30-year-old male patient with progressive left upper limb and bilateral lower limb weakness over a period of 3 months, associated with an unsteady gait. Clinical examination revealed bilateral generalized hyper-reflexia in both upper and lower limbs, inverted supinator jerk, Hoffman’s sign and clonus. Myelopathy due to cord compression was suspected and further investigations were done. MRI and CT scans revealed a bony mass in relation to the C6 spinous process projecting anterosuperiorly and narrowing the cervical spinal canal causing cord signal changes from C4 to C6 levels. In view of the deteriorating neurological status, immediate surgery in the form of decompression and posterior stabilization from C4-C6 was performed. Patient gradually recovered after surgery and attained full functional status. We report this case considering the unusual location of OYL and its successful management
Evaluation of the serum β2 Microglobulin level in patients with systemic lupus erythematosus and its correlation with disease activity
No full textBackground: Designation of disease activity is serious for the management of systemic lupus erythematosus (SLE). Serum level of β2 microglobulin (β2M) may be associated with illness activity in SLE disease. Since the role of β2M for assessing of illness activity in SLE is not completely clear, the current study aimed to discern evaluation of β2M in patients with SLE and its correlation with sickness activity.
Materials and Methods: In this case-control study, 50 patients with SLE disease and 25 healthy individuals were selected in Imam Khomeini Hospital in central of Urmia.
Blood samples were collected safely from patients, serum was removed, and β2M measured using an ELISA method. The results for other parameters including C reactive protein, C3, C4, anti dsDNA and erythrocyte sedimentation rate were obtained from patients’ medical record. Data analyzed using appropriate statistical tests including Mann-Whitney U test, Independent f-test,Kruskal-Wallis,and Spearman used for analysis of data.
Results: In the current study, a significant difference was seen between two groups in terms of β2M (p \u3c 0.001). Remarkable correlation was seen between the level of β2M with disease activity (p \u3c 0.001). Furthermore, there are significant relevancy between the level of β2M with 24-hour urine protein, ESR, disease activity score, and CRP (p \u3c 0.05).
Conclusion: The results revealed that serum amount of β2M in SLE patients is higher compared to healthy ones, which is significantly correlated to score of illness activity, CRP, and ESR in patients with SLE disease. Hence β2M might be an excellent serological marker helping the prediction of sickness activity and inflammation in SLE patients
Cohort study of microelement status in “healthy” population of Russian megapolis
No full textThe aim of the study was at the cohort assessment of microelement status in large city residents classified as “apparently healthy people”. The population study included 2,025 randomly selected middle-aged (2045 years) persons without chronic diseases or acute infectious pathologies. The set of subjects was standardized by age and gender. A blood sample was taken once from each person to determine concentrations of microelements. The level of peripheral blood microelements were determined by atomic absorption spectrometry using «Shimadzu AA7000» device (Japan). The study of a large population of city residents demonstrated inhomogeneity in their microelement status. Deficit conditions were found for a number of values, including concentrations of potassium, sodium, nickel, stibium, chromium and cadmium. At the same time, there are large proportions of persons with low plasma concentrations of copper and even lower plasma concentrations of zinc and magnesium. On the contrary, 42% of the persons show high concentrations of lithium. Such disturbances of microelement homeostasis (pre-pathological condition) make it necessary to perform targeted correction for the purpose of preventing the development of pathological conditions associated with microelement deficiencies
The judet quadricepsplasty for elderly traumatic knee extension contracture: a case report and review of the literature
No full textTraumatic injuries to the knee are frequently complicated by extension contractures. The Judet Quadricepsplasty allows for controlled, sequential release of extrinsic and intrinsic knee contracture components while reducing the potential for iatrogenic quadriceps rupture. We document our institutions experience with this procedure and a systematic review of the current literature. We followed up on an elderly patient with posttraumatic flexion contracture that failed conservative management and underwent Judet Quadricepsplasty. Her knee range of motion improve dramatically from 20 degrees of flexion to 100 degrees of flexion. There was a residual extension lag of 5 degrees which did not impede on the patients daily activities. A review of the literature was performed and relevant data from 12 articles was extracted. The procedure was mainly performed in young adult males in most previous studies and the range of motion improvement ranged from 51° to 110°. Wound infections were the most common complication but otherwise other complications and severe extension lag were rare. The Judet Quadricepsplasty is a useful procedure for severe extension knee contractures that has failed conservative management in all age groups of patients. It is associated with significant increases in range of motion with low rates of complication or extension lag.

A combined nasolabial and infra-nasal bi-lobe flap design with double transposition for reconstruction of the ipsilateral upper and lower lips associated with the commissure defect
No full textSeveral classical flap variations have been designed to reconstruct lip and commissure defects. Although most of these variations maybe the best option for repairing defects, there is an increasing risk of anatomic distortion and functional disability, mostly in older persons. Herein, we present a combined nasolabial and infra-nasal bi-lobe flap design with double transposition, which was used to concomitantly close the upper and lower lips associated with commissure defects
Artificial intelligence (AI)-powered bibliometric analysis of global trends in mesenchymal stem cells (MSCs)-derived exosome research: 2014-2023
No full textIntroduction: In recent years, significant progress has been made in regenerative medicine, specifically in using mesenchymal stem cells (MSCs) due to their regenerative and differentiating abilities. An exciting development in this area is the utilization of exosomes derived from MSCs, which have shown promise in tissue restoration, immune system modulation, and cancer treatment.

VKORC1 polymorphisms and complete resistance to Vitamin K antagonists: About two cases.
No full textComplete resistance to vitamin K antagonists is a rare but serious. It can complicate therapeutic management, especially when direct oral anticoagulants cannot be used. Some single mutations in the VKORC1 gene have been identified in patients partially or completely resistant to vitamin K antagonists. We report the cases of two women in their fifties who presented an unexplained peripheral venous thrombosis. The aetiological assessment did not show any abnormalities. Genetic testing showed that both patients had the VKORC1 5417GG genotype. The VKORC1 3673 genotype was GG in case 1 and GA in case 2. The two patients showed complete resistance to vitamin K antagonists which required a change in treatment with favourable outcomes. Our goal is to offer optimal care guided by a literature review
