Abstract
Background: Thyroid hormones (THs) signaling has profound effects on many physiological processes. The regulation of THs signaling in various tissues involves the action of microRNAs (miRNAs) on thyroid deiodinases and receptors. THs regulate the expression of certain miRNAs and their target messenger RNAs (mRNAs) in various tissues and cells. The modulation of miRNA levels by THs affects their functions in processes such as liver lipid metabolism, skin physiology, and muscle and heart performance. Aim: This research aimed to investigate miR-181b, miR-206, and miR-21 in the serum of patients with subclinical and overt hypothyroidism to determine their possible role in the diagnosis of the disease and their relationship to clinical disorders related to hypothyroidism. Methods: This study included ninety participants, divided evenly into three groups as follows: patients with overt hypothyroidism diagnosed clinically, radiologically, and by investigation, subclinical hypothyroid patients, and healthy volunteers. The patients had a thorough medical history and underwent a clinical examination. Laboratory tests included plasma cholesterol, LDL, HDL, TGs, liver and renal function tests, CBC, fasting insulin, HOMA-IR, HbA1c, TSH, and free T4. The serum levels of miR-21, miR-206, and miR-181b were measured using qRT-PCR. Results: miR-206 and miR-181b levels were higher in the subclinical group, followed by the hypothyroid and control groups. For miR-21, there was a significantly lower mean value in both the hypothyroid and subclinical groups than in the control group, with no difference between the two groups. Both miR-206 and miR-181b showed a significant negative association with albumin and free T4 levels and a significant direct association with GGT, ALT, AST, creatinine, uric acid, TGs, TC, LDL, TSH, thyroid volume, and CAP score. The same correlation pattern was observed for miR-181b, except that it was not significantly correlated with the TGs. For miR-21 levels, there was a significant positive correlation with albumin, free T4 level, and kPa score and a negative correlation with GGT, ALT, AST, creatinine, uric acid, HOMA-IR, HbA1c, TC, LDL, TSH, and CAP score. Cases with F1 kPa score and S2 CAP scores had significantly higher averages for miR-206 and miR-181b, with a p-value of 0.05. Moreover, miR-21 levels were significantly lower in the S2 CAP score group. Conclusion: These miRNAs (miR-206, miR-181b, and miR-21) may be used as diagnostic biomarkers for hypothyroidism. They may be used as therapeutic targets to control dyslipidemia and hepatic steatosis during hypothyroid disease.

Abstract
BACKGROUND & AIMS Inflammatory bowel disease (IBD), involving both Crohn's disease (CD) and ulcerative colitis (UC), represents a chronic, immune-mediated inflammatory disease due to an uncontrolled, ongoing inflammatory response to intestinal bacteria in those with genetic susceptibility. MicroRNA (miRNA) extrusion from relevant remote organs or tissues is reflected in the expression of miRNAs in serum and plasma. Both UC and CD patients had higher blood levels of expressed miR-199a. Long noncoding RNA (lncRNA) ANRIL is a proinflammatory gene that mediates nuclear factor κB to play a role in inflammatory diseases, such as IBD. The aim of the current study is to investigate the potential role of both miR-199a and ANRIL in diagnosing IBD in adult patients. METHODS Sixty-seven IBD patients diagnosed clinically, radiologically, endoscopically, and histologically were included in this prospective cohort study. Participants were classified into 3 groups: the UC group (n = 35), the CD group (n = 32), and the control group (n = 30). Demographics, history taking, laboratory characteristics, and treatments were recorded. Tumor necrosis factor α , miR-199a, and ANRIL were measured. RESULTS The findings suggested that miR-199a and ANRIL might be associated with the occurrence or progression of IBD because both genes were substantially expressed in the peripheral blood of patients with this condition. Receiver-operating characteristic curve analysis indicated that the detection of miR-199a and ANRIL had a predictive sensitivity of 62.9% and 88.6% and a specificity of 70.7% and 96.7% for the occurrence of UC cases, respectively, and a predictive sensitivity of 72.4% and 46.9% and a specificity of 96.7% and 34.7% for the occurrence of CD cases, respectively. CONCLUSIONS Both miR-199a and ANRIL are abundant in the sera of IBD adult Egyptian patients (UC and CD). Both can represent a noninvasive marker for early disease diagnosis.

Abstract
Psoriasis is a persistent inflammatory skin disorder driven by T cells. The disease is characterized by aberrant keratinocytes (KCs) differentiation, epidermal proliferation, and excessive hyperplasia of veins and arteries. The purpose of the study was to identify the levels of circulating lnc-HULC, miR-122, and Sirtuin 1 (SIRT-1) in psoriatic patients, evaluate their possible roles as diagnostic biomarkers, and link their levels with the development of metabolic syndrome during psoriasis progression. This study included 176 participants. The subjects were divided into four groups, with 44 participants in each group. All patients have undergone a complete history taking and clinical examination. Laboratory investigations included Low-density lipoprotein (LDL), High-density lipoprotein (HDL), Triglycerides (TG), Fasting blood sugar (FBS), and cholesterol plasma levels. Serum levels of miR-122 and lnc-HULC were examined by qRT-PCR. Serum levels of SIRT-1 were examined by ELISA. The serum concentrations of lnc-HULC and miR-122 were significantly higher in psoriatic participants compared to controls. Psoriatic patients' serum concentrations of SIRT-1 were much lower than those of healthy individuals. There was a negative association between SIRT-1 concentration and BMI, disease duration, PASI score, LDL, and cholesterol levels. The blood levels of lnc-HULC, miR-122, and SIRT-1 in psoriasis patients provide a promising role as diagnostic biomarkers in patients with and without metabolic syndrome.

Abstract
Objective: RNA-based mechanisms of epigenetic modification related to acute ischemic stroke (AIS) have been widely studied recently. The current work aimed to determine the potential roles of four ncRNAs (TUG1 and its target miR-21, NBAT1, and miR-335) as promising diagnostic biomarkers in AIS as well as their involvement in the disease pathogenesis. Methods: The levels of the studied lncRNAs and miRNAs were measured in the serum for two different groups, including patients with AIS (60) and healthy controls (60). All individuals were subjected to a full history investigation and clinical examination. Blood samples were tested for FBS, 2HPP, TAG, HDL, LDL, TSH, T3, and T4 levels. Results: The serum levels of TUG1 were significantly increased in AIS patients compared to control subjects. It is worthwhile to note that serum TUG1 levels were positively correlated with cholesterol, triglycerides, LDL, carotid IMT (Intima-media thickness), and miR-21, while they were negatively correlated with HDL levels. Our study showed that NBAT1 serum expression levels were elevated in AIS patients compared to controls. NBAT1 expression levels were observed to be positively correlated with triglycerides, TUG1, and miR-21. NBAT1 could distinguish between AIS patients and controls with a sensitivity of 100% and specificity of 100% at a cut-off point of 1.45. Regarding miR-335, we found that its expression levels were downregulated in AIS patients compared with healthy controls. It could distinguish between AIS patients and controls with a sensitivity of 73.3% and a specificity of 100% at a cut-off point of 0.796. Conclusion: Our results revealed that serum TUG1, miR-21, NBAT1, and miR-335 could be promising molecular diagnostic markers for AIS as these biomarkers could discriminate between AIS patients and healthy controls.

Abstract
Introduction: Autosomal recessive variations in NPHS1 gene represent common cause of congenital nephrotic syndrome (CNS). The disease is characterized by considerable proteinuria presenting in the first 90days of life. CNS has a poor outcome and usually leads to end stage renal disease by 2-3 years of life. NPHS1 encodes the protein nephrin, expressed in inter-podocyte slit diaphragm. Aim of work: The main objective of this cross-sectional study was to perform the analysis of the NPHS1 gene in 24 Egyptian patients with CNS aiming to determine the molecular cause of the disease and to detect their phenotype/genotype correlations. Methods: Polymerase chain reaction followed by direct sequencing of exons (3,4,6,7,18,19) of NPHS1 gene was performed in 24 neonates with CNS with median age 25 days (1-90 day). Results: three pathogenic variants were detected in five patients. They were one frame shift variant in exon 19, one missense de novo variant in exon 6 and one In-frame deletion variant in exon 4. Three benign variants were seen in seven patients in exon and intron 3. Conclusion: although the number of patient included in the study is small, but the results of the study presented de novo likely pathogenic mutation in exon 6 not reported before in 2 patients and 2 reported pathogenic variants. Molecular diagnosis is advised to be performed early in the diagnosis of CNS to avoid unnecessary immunesupp-ression and start early suitable treatment.

Abstract
Objective: This study aimed to compare efficacy and safety of lidocaine versus tramadol versus placebo in reducing the pain of diagnostic outpatient hysteroscopy (OH) in postmenopausal women.Materials and methods: This randomized double-blinded study included 156 menopausal women who received intrauterine lidocaine infusion or oral tramadol (50 mg) or placebo before diagnostic OH (52 women/group). Primary outcome was pain severity during the procedure using a 10-cm visual analog scale. Secondary outcomes were pain scores 10 and 30 min post procedure, satisfaction level, and ease of cervical entry.Results: Lidocaine had lower pain scores compared to placebo during and 10 min after the procedure (p < 0.001). Tramadol had lower pain scores than placebo during the procedure (p = 0.04), 10 min after the procedure (p = 0.03), and 30 min after the procedure (p = 0.04). Both lidocaine and tramadol resulted in an easier procedure than placebo (p < 0.001 and p = 0.04, respectively). Lidocaine had an easier cervical entry compared to tramadol (p = 0.004). Satisfaction scores in the lidocaine and tramadol groups were significantly higher than in the placebo group (p < 0.001).Conclusions: Lidocaine and tramadol were effective in reducing postmenopausal women-reported pain during and after diagnostic OH. However, lidocaine was better than tramadol in facilitating hysteroscope passage through the cervical canal and the reduction in pain levels with lidocaine was clinically relevant.Trial registration number: NCT03701984.

Abstract
Objectives The aim of this study was to determine the prevalence of extended-spectrum β-lactamase (ESBL) and carbapenemase production among Enterobacteriaceae isolated from ambulatory patients with gastrointestinal complaints admitted to El-Ahrar General Hospital, Zagazig, Egypt in the period between January 2013 and May 2013. Methods One hundred and thirteen Enterobacteriaceae isolates were recovered from 100 consecutive Egyptian patients with community–onset gastrointestinal complaints. The fecal samples were plated directly on selective EbSA-ESBL Screening Agar and on MacConkey agar. Isolate identification was performed with matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS). Screening for ESBLs and carbapenemases production was done by both the automated VITEK®2 system with AST N198 and by disk diffusion method. Real-time PCR and sequencing were used to characterize the resistance genes. Phylogroups of the E. coli isolates were determined by a triplex PCR-based method. Results Of 100 patients screened for fecal colonization with extended-spectrum β-lactamase -producing Enterobacteriaceae (ESBL-E) and carbapenemase- producing Enterobacteriaceae (CPE), 68 were colonized with ESBL-E whereas five patients were positive for CPE. One hundred and thirteen Enterobacterceae isolates were recovered from 100 fecal samples, they belonged to E. coli (n = 72), Klebsiella pneumoniae (n = 23), Enterobacter cloacae(n = 3), Salmonella spp. (n = 1) and other Enterobacterceae isolates (n = 14). The blaCTX-M gene was detected in 89.04% (65/73) of the ESBL-producing Enterobacteriaceae, whereas blaSHV and blaTEM were detected in 30.14% (22/73) and 19.18% (14/73) respectively. Three out of 5 carbapenem-resistant isolates harbored New Delhi metallo-beta-lactamase (NDM) and 2 produced Verona integron-encoded metallo- beta -lactamase (VIM). Twenty-two (47.83%) of the ESBL positive isolates were multidrug resistant (MDR). Phylogenetic analysis showed that, of the 51 ESBL-EC isolates, 17 belonged to group B2, 13 to group D, 11 to group A and 10 to group B1. Conclusions Nearly two-thirds of the Enterobacteriaceae isolates recovered from feces of ambulatory patients with community–onset gastrointestinal complaints admitted to El-Ahrar General Hospital, Zagazig, Egypt were ESBL producers and one in every 20 patients included in our study was colonized by carbapenemase-producing Enterobacteriaceae. These high colonization rates are worrying, therefore prudent antimicrobial use should be adopted in Egyptian community settings.

Abstract
A five-month-old male Shiraze cat was referred to the Mansoura Veterinary Teaching Hospital of Mansoura University, Mansoura, Egypt for evaluation of a 5-days history of swelling in the caudal ventral abdomen after trauma, persistent straining and inability to urinate. Clinical examination, abdominal ultrasonography and exploratory laparotomy revealed herniation and herniorraphy was attempted. The herniated organs were urinary bladder and intestine through an abdominal wall defect. Clinical signs resolved after surgical reduction of the intestine and urinary bladder. Follow-up by telephone three months postoperatively confirmed that the cat had no problems with defecation or micturition. Entero-cystocele in a young cat after trauma has not been reported previously to the author’s knowledge.

Abstract
It is almost a decade since the highly pathogenic H5N1 avian influenza virus (A/H5N1) of clade 2.2.1 was introduced to Egypt in 2005, most likely, via wild birds; marking the longest endemic status of influenza viruses in poultry outside Asia. The endemic A/H5N1 in Egypt still compromises the poultry industry, poses serious hazards to public health and threatens to become potentially pandemic. The control strategies adopted for A/H5N1 in Egyptian poultry using diverse vaccines in commercialized poultry neither eliminated the virus nor did they decrease its evolutionary rate. Several virus clades have evolved, a few of them disappeared and others prevailed. Disparate evolutionary traits in both birds and humans were manifested by accumulation of clade-specific mutations across viral genomes driven by a variety of selection pressures. Viruses in vaccinated poultry populations displayed higher mutation rates at the immunogenic epitopes, promoting viral escape and reducing vaccine efficiency. On the other hand, viruses isolated from humans displayed changes in the receptor binding domain, which increased the viral affinity to bind to human-type glycan receptors. Moreover, viral pathogenicity exhibited several patterns in different hosts. This review aims to provide an overview of the viral evolution, pathogenicity and vaccine efficacy of A/H5N1 in Egypt during the last ten years.

Abstract
PURPOSE To examine the effect of topical treatment with either steroidal or nonsteroidal anti-inflammatory drugs (NSAIDs) on the wound healing of corneal and limbal incisions using histologic criteria. SETTING Loyola University Medical Center, Maywood, Illinois, USA. METHODS Eighteen eyes of 9 cats were used for the study. All right eyes received a temporal limbal incision and the left eyes, a clear corneal incision. All eyes were treated with ofloxacin 0.3% postoperatively for 3 days. The animals were equally divided among 3 groups. Group 1 received topical steroid drops (prednisolone acetate 1%) for 7 days maximum; Group 2 received topical NSAID drops (ketorolac tromethamine 0.5%) for 7 days maximum; Group 3 received no additional treatment. One animal from each group was killed and the eye enucleated 3, 7, or 28 days postoperatively. The eyes were processed for staining with hematoxylin-eosin and smooth muscle actin, and corneal sections were evaluated in a blind fashion by an ophthalmic pathologist. RESULTS Three and 7 days after surgery (1) the limbal incision exhibited more prominent wound healing than the similarly treated clear corneal incision, and (2) the steroid-treated corneas had less wound healing than untreated or NSAID-treated corneas. At 28 days, the wounds in all eyes were almost completely healed. CONCLUSIONS Limbal incisions heal faster than clear corneal incisions. Steroids, but not NSAIDs, inhibit wound healing. Cataract surgery using limbal incisions and postoperative topical NSAIDs may result in faster wound healing and provide a reduced risk of related postoperative complications.

Abstract
Based on the hypothesis that a systematic, carefully planned educational approach to leprosy would yield results in terms of knowledge, attitudes and case presentation superior to those of the established and traditional mass survey method, ALERT-India launched a programme in S ward of Bombay in February 1985, to compare the two. An intensive programme of health education, using trained teams, was carried out in one zone of this ward over a period of 12 months. Eight months later, mass survey work (as used routinely in previous years and on a country-wide basis) was carried out in an adjacent zone. In 1987, the Centre for Social and Technological Change in Bombay, in association with the School of Oriental and African Studies, University of London, was requested to evaluate the effect of the above educational approach in terms of knowledge, attitudes and practice in both the trial and control zones. Other aspects of this experimental approach, including its cost and effectiveness in identifying cases of leprosy, will be published separately. The design of the 'KAP' evaluation and the social and environmental controls introduced in the statistical analysis are described. The results pointed to a considerable degree of ignorance about leprosy as a disease (and its treatment) in both the study and the control zones. Knowledge about early symptoms was particularly weak and on all aspects scores for women were invariably lower than men. General education enhanced the absorption of specific knowledge, and the education of children compensated adequately for lack of parental education in this respect. Overall the evaluation indicated that the intensive educational approach was superior to the survey approach in terms of improving knowledge, attitudes and practice.
