Plate Objective Scoring Tool (POST) in distal hypospadias: Correlation with post-repair complications.

OBJECTIVES: The Plate Objective Scoring Tool (POST) accurately reflects configuration of the urethral plate in distal hypospadias. Here we assessed whether POST score also correlates with patient risk of complications after surgical repair. METHODS: Data were obtained prospectively from pre-pubertal boys who underwent primary hypospadias repair between January 2020 and February 2023. Both POST and Glans-Urethral Meatus-Shaft (GMS) scores were determined in triplicate by three independent reviewers before evaluating correlation with complications after surgery. RESULTS: POST ratios were strongly correlated with incidence of post-repair complications in n = 121 patients. Mean POST score was 1.10 (range 0.5-1.62) and average GMS value was 5.29 ± 1.36 (median G = 2, M = 2, S = 1). Bivariate correlation analysis indicated that POST score can accurately predict risk of complications after surgery (Pearson correlation coefficient r = 0.821 [0.724-0.918], 95 % CI). A POST threshold of 1.2 provided the highest specificity for risk of post-operative complications, which occurred in 4.4 % of patients with POST score ≥1.2 (2/45 cases), compared with 25 % among patients with POST score <1.2 (19/76 cases). CONCLUSIONS: This study confirms that POST index can be used as a surrogate marker of urethral plate quality and accurately predicts the outcome of distal hypospadias repair. Objective scoring of POST revealed that low ratios were significantly associated with high risk of postoperative complications. In future, this approach could be used to stratify patients and better identify cases that require close follow-up care.

Bilateral large cell calcifying Sertoli cell tumours: A testicular preservation approach in a young male.

Testicular Large cell calcifying Sertoli cell tumours (LCCSTs) are extremely rare. The primary challenge in benign LCCSTs, which are typically multifocal and bilateral tumours affecting young males, is to confirm the diagnosis to avoid radical intervention and preserve fertility potential. Patient clinical presentation, laboratory results, diagnostic radiological tests along with confirmatory histopathological studies, are the cornerstones in such cases, nevertheless genetic testing is warranted, as LCCSTs can be part of genetic syndrome such Carney complex. We present a case of bilateral benign LCCSTs in young male managed with testicular preservation approach with characteristic clinical, radiological and histopathological features.

Recurrent urinary retention due to seminal vesicle cyst a report of rare entity.

Male pelvic cyst rarely causes symptoms; here, we are presenting a case of a 48-year-old gentleman who presented with acute urinary retention stemming from a pelvic cyst. This presentation has been recurrent despite undergoing repeated TRUS aspiration of the cyst to relieve the symptoms. We performed a robotic pelvic cyst excision with peritoneal window in an attempt to cure the patient. Based on the MRI and histopathology, it was likely a seminal vesicle cyst that is causing these recurrent episodes. On 3 months follow-up, the patient was symptom free without any complaints.

Management of acute aortic syndrome with evolving individualized precision medicine solutions: Lessons learned over two decades and literature review.

Background: Thoracoabdominal acute aortic syndrome is associated with high morbidity and mortality. We aim to scrutinize our evolving strategies for acute aortic syndrome (AAS) management using minimally invasive and adaptive surgical techniques over two decades. Methods: This is a longitudinal observational study at our tertiary vascular centre from 2002 to 2021. Out of 22,349 aortic referrals, we performed 1,555 aortic interventions over twenty years. Amongst 96 presented with symptomatic aortic thoracic pathology, 71 patients had AAS. Our primary endpoint is combined aneurysm-related and cardiovascular-related mortality. Results: There were 43 males and 28 females (5 Traumatic Aortic Transection (TAT), 8 Acute Aortic Intramural Hematoma (IMH), 27 Symptomatic Aortic Dissection (SAD) and 31 Thoracic Aortic Aneurysm (TAA) post-SAD) with a mean age of 69. All the patients with AAS received optimal medical therapy (OMT), but TAT patients underwent emergency thoracic endovascular aortic repair (TEVAR). Fifty-eight patients had an aortic dissection, of which 31 developed TAA. These 31 patients with SAD and TAA received OMT initially and interval surgical intervention with TEVAR or sTaged hybrId sinGle lumEn Reconstruction (TIGER). To increase our landing area, we performed a left subclavian chimney graft with TEVAR in twelve patients. The average follow-up duration was 78.2 months, and eleven patients (15.5%) had combined aneurysm and cardiovascular-related mortality. Twenty-six percentage of the patients developed endoleaks (EL), of which 15% required re-intervention for type II and III. Four patients who had paraplegia (5.7%) and developed renal failure died. None of our patients had a stroke or bowel ischaemia. Twenty patients had OMT, eight of these were patients with acute aortic hematoma, and all eight died within 30 days of presentation. Conclusion: Acute aortic hematoma is a sinister finding, which must be closely monitored, and consideration is given to early intervention. Paraplegia and renal failure result in an increased mortality rate. TIGER technique with interval TEVAR has salvaged complex situations in young patients. Left subclavian chimney increases our landing area and abolishes SINE. Our experience shows that minimally invasive techniques could be a viable option for AAS.

Regulation of IGF2BP1 by miR-186 and its impact on downstream lncRNAs H19, FOXD2-AS1, and SNHG3 in HCC.

AIM: We have previously characterized oncogenic properties of IGF2BP1 in HCC, and its regulation by short noncoding RNAs (ncRNAs). Recent evidence suggests that IGF2BP1 itself may regulate long ncRNAs (lncRNAs). Therefore, this study aimed at exploring the interplay between IGF2BP1 and various upstream and downstream ncRNAs and its link to HCC pathogenesis. MATERIALS AND METHODS: Bioinformatic analysis was used to identify up- and downstream ncRNAs interacting with IGF2BP1. Huh-7 cells were transfected with siRNAs against IGF2BP1 and microRNA mimics. Relative gene expression was determined using RTqPCR and IGF2BP1 protein was quantified by western blot. Luciferase binding assay was used to explore the targeting of IGF2BP1 3'UTR. HCC tumorigenesis was measured by MTT assay, BrdU-incorporation assay, colony-forming assay, and scratch assay. KEY FINDINGS: Bioinformatic analysis identified three oncogenic lncRNAs - namely H19, FOXD2-AS1, and SNHG3 - potentially regulated by IGF2BP1. Knockdown of IGF2BP1 decreased the expression of all three oncogenic lncRNAs and inhibited malignant cell behaviors. miR-186 was revealed as a possible upstream regulator of IGF2BP1. miR-186 mimics decreased IGF2BP1 mRNA and protein levels. miR-186 was significantly lower while IGF2BP1 was elevated in cancerous tissues from ten HCC patients compared to five healthy controls. In addition, miR-186 mimics caused a downregulation of the oncogenic lncRNAs H19, SNHG3, and FOXD2-AS1 and a concomitant decrease in cell viability, proliferation, migration, and clonogenicity. SIGNIFICANCE: miR-186 may exert tumor suppressor effects in HCC by repressing oncogenic lncRNAs H19, SNHG3, and FOXD2-AS1 through its effect on IGF2BP1.

Metachronous bilateral spontaneous spermatic vein thrombosis: A rare cause of orchialgia.

Scrotal pain and swelling are common presentation, the prompt evaluation and diagnosis is needed due to wide range of causes, uncommon causes of orchialgia should be kept in mind whenever there is no clear diagnosis. Spermatic vein thrombosis usually presents with orchialgia along with episodes of acute exacerbation of pain. The diagnosis is challenging and need high index of suspension and detailed radiological evaluation. We present a case of metachronous bilateral unprovoked spermatic vein thrombosis treated conservatively with anticoagulation with good response and resolution of symptoms.

Plate Objective Scoring Tool: A new preoperative indicator of penile curvature degree in children with distal hypospadias.

OBJECTIVES: There is an unmet need for preoperative methods that surgeons can use to objectively quantify hypospadias anatomic variables and determine risk of penile curvature. We, therefore, assessed whether Plate Objective Scoring Tool measurements were correlated with degree of ventral curvature in affected children. METHODS: Patients undergoing distal hypospadias repair were enrolled into the study between January 2018 and December 2020 and were categorized independently by at least two surgeons using Plate Objective Scoring Tool. Scores were compared statistically to determine the degree of ventral curvature and requirement for correction. RESULTS: Sixty-five patients with a median age of 18 months (interquartile range 13-26) were enrolled into the study prior to surgery for primary distal hypospadias. Patient probability of significant postoperative curvature (>20°) was determined with moderate confidence using a cutoff Plate Objective Scoring Tool score of 1 (sensitivity 75%, specificity 60%). Presurgery Plate Objective Scoring Tool scores were negatively correlated with subsequent degree of curvature (r = -0.37, P = 0.003), with values <1.0 predicting >20° curvature. CONCLUSIONS: Plate Objective Scoring Tool scoring offers a succinct method of describing hypospadias severity and correlates well with postoperative outcomes. The Plate Objective Scoring Tool system can therefore be used to objectively predict the likelihood of penile curvature and aid communication between surgeons and researchers, as well as improving parental counseling.

A cross-sectional study of the genital duct and renal anomalies in Egyptian cases of congenital absence of the vas deferens.

The aim of the study was to detect the incidence and types of genital and renal duct anomalies associated with congenital absent vas deferens (CAVD). In 200 males with CAVD, the demographic characteristics, physical examination findings were evaluated. Scrotal ultrasonography and transrectal ultrasonography (TRUS) were used as the diagnostic methods for evaluating unilateral or bilateral CAVD with associated abnormalities or agenesis of the testes, epididymes, seminal vesicles and prostate. Abdominal ultrasound was performed to detect any associated renal anomalies. There were a total of 111 CBAVD and 89 CUAVD males. Eight cases (8.98%) of CUAVD were associated with contralateral cryptorchidism. In most cases there were agenesis in the epididymal body and tail and seminal vesicles. Different types of renal anomalies (32.50%) especially renal agenesis were observed mainly in cases of left CUAVD and were predominately on the left hand side. An important implication of our study is the importance of requesting ultrasound of males with CAVD to discover any associated anomalies especially renal agenesis that may be ignored by many physicians.

Hepatocellular carcinoma cell line-microenvironment induced cancer-associated phenotype, genotype and functionality in mesenchymal stem cells.

Mesenchymal stromal cells (MSCs) have shown promise in liver cancer treatment. However, when MSCs are recruited to hepatic site of injury, they acquire cancerous promoting phenotype. AIMS: To assess the influence of Hepatocellular carcinoma (HCC) microenvironment on human adipose MSCs (hA-MSCs) and predict hA-MSCs intracellular miRNAs role. MATERIALS AND METHODS: After indirect co-culturing with Huh-7 cells, hA-MSCs were characterized via cell cycle profile, proliferation and migration potentials by MTT and scratch assays respectively. Functional enrichment analysis of deregulated proteins and miRNA targets was also analyzed. KEY FINDINGS: Co-cultured hA-MSCs could acquire a cancer-associated phenotype as shown by upregulation of CAF, cancer markers, and downregulation of differentiation markers. Migration of these cancer-associated cells was increased concomitantly with upregulation of adhesion molecules, but not epithelial to mesenchymal transition markers. Co-cultured cells showed increased proliferation confirmed by downregulation in cell percentage in G0/G1, G2/M and upregulation in S phases of cell cycle. Upregulation of miR-17-5p and 615-5p in co-cultured hA-MSCs was also observed. Functional enrichment analysis of dysregulated proteins in co-cultured hA-MSCs, including our selected miRNAs targets, showed their involvement in development of cancer-associated characteristics. SIGNIFICANCE: This study suggests an interaction between tumor cells and surrounding stromal components to generate cancer associated phenotype of some CAF-like characteristics, known to favor cancer progression. This sheds the light on the use of hA-MSCs in HCC therapy. hA-MSCs modulation may be partially achieved via dysregulation of intracellular miR17-5P and 615-5p expression, suggesting an important role for miRNAs in HCC pathogenesis, and as a possible therapeutic candidate.

Evaluation of the potential role of shear wave elastography as a promising predictor of sperm retrieval in non-obstructive azoospermic patients: A prospective study.

BACKGROUND AND OBJECTIVES: Testicular sperm extraction (TESE) has been a useful diagnostic and therapeutic tool with sperm retrieval opportunity varying according to the pathological finding in azoospermic patients. Sonoelastography (SE) is an exciting radiologic method that can measure relative elasticity of different tissues in a selected region of interest (ROI) by depending on fast cross-correlation technique and a combined autocorrelation method. Real-time elastography (RTE) can be used for structural analysis of testicular tissue to detect pathological tissue alterations. We aimed in the current study to evaluate the efficacy of shear wave elastography (SWE) in predicting sperm retrieval in non-obstructive azoospermic (NOA) patients undergoing TESE. PATIENTS AND METHODS: This prospective study included 50 NOA patients who did two successive semen analyses with normal or elevated gonadotrophic hormones. All participants were subjected to SWE imaging on the testes by a radiologist. The measurements were recorded in terms of kPa using the SWE mode. They were done on each testis in the longest longitudinal plane. SWE images were viewed using dual mode: elasticity mode (kPa) and propagation (arrival time contour) mode then patients underwent TESE. RESULTS: A significant difference in SWE values was observed between patients with successful sperm retrieval and those with negative sperm retrieval providing 94.7% negative predictive value and 50.0% positive predictive value for sperm retrieval in NOA patients undergoing TESE with 75.0% sensitivity and 85.71% specificity (p  =  0.0001). Mean stiffness index measured by SWE correlated significantly with the histopathological types as 8 patients only were diagnosed as having severe hypospermatogenesis. DISCUSSION AND CONCLUSION: These prime data suggest that SWE as a non-invasive, easily applicable, and repeatable imaging method has a promising potential to be one of the reliable sonographic modalities that can be used as one of the predictors for sperm retrieval in NOA patients.

Association of Rs231775 Genetic Variant of Cytotoxic T-lymphocyte Associated Protein 4 with Alopecia Areata Disease in Males: A Case-Control Study.

BACKGROUND: Alopecia Areata (AA) is a common inflammatory immune-mediated non-scarring hair loss; however, the exact genetic susceptibility remains to be clarified. Cytotoxic T-lymphocyte Associated Protein 4 (CTLA4) has emerged as a central and critically important modulator of immune responses and is believed to play a crucial rule in AA pathogenesis. OBJECTIVES: To investigate the association of CTLA4 variant (rs231775) within codon 17 with AA risk and outcomes. METHODS: Genetic analyses of the rs231775 SNP of CTLA4 gene were performed in 186 males (93 AA patients and 93 controls). RESULTS: The rs231775 CTLA4 variant was significantly higher in AA patients in comparison with control subjects especially among heterozygous and dominant model. This association varied significantly with disease severity. CONCLUSIONS: Individuals with homozygosity of rs231775 CTLA4 variant represented AA disease risk and increased severity than their counterparts.Abbreviations: AA: Alopecia areata; CTLA4: Cytotoxic T-lymphocyte Associated Protein 4; SNP: Single nucleotide polymorphism; LADA: Latent autoimmune diabetes in adults; SLE: Systemic lupus erythematosus; SCU: Suez Canal University; SALT: Severity of Alopecia Tool; DNA: Deoxyribonucleic acid; RT-PCR: Real-time polymerase chain reaction, HWE: Hardy-Weinberg equation; RA: rheumatoid arthritis.

Strengths of community and health facilities based interventions in improving women and adolescents' care seeking behaviors as approaches for reducing maternal mortality and improving birth outcome among low income communities of Egypt.

BACKGROUND: Provision of emergency obstetric care is considered the key for maternal mortality reduction worldwide. This study evaluated the impact of community- and facility-based educational programs on provision of emergency obstetric care in Egypt. The study focused on evaluating utilization of the available health services and care seeking behaviors of mothers in the childbearing period. METHODS: We implemented a package of community- and facility-focused educational interventions in two of Egypt's lowest income governorates. At facility level, health professionals at rural health units from 21 villages over 5 years were trained. Mass media gathering, individual teaching at health facilities, printed materials and home-based care sessions were provided. Collectively, these interventions were designed to focusing on recognition of the early warning signs during pregnancy, delivery and postpartum period for timely referral to hospitals for 20,494 women and adolescents mothers. RESULTS: The impact of the interventions was highly reflected on the percent of mothers received care during their pregnancy period. Proper antenatal care at governmental or private health facilities was raised dramatically from 0.6 to 59.3% and those who utilized at least one family planning method from 61.4 to 74.4%. Accordingly, the rate of complications significantly reduced during pregnancy (38.1 to 15.1%), during delivery (24.1 to 13.1%) and during postpartum (81.7 to 7.0%). As an impact to the improvement, there was a marked reduction in adolescent pregnancy by 55% and better birth outcome with a reduction in the percent of stillbirth by 11.5%. CONCLUSION: It is important to provide a comprehensive package that works at both improving qualities of care as well as empowering women by knowledge to first aid measures at the community level. The cost-effective way to empower mothers to provide first aid measures as emergency obstetric care is to adopt the outreach approach which could be more influential than mass media campaigns for the at-risk and vulnerable and low-income communities.

Extraction, purification of prostate-specific antigen (PSA), and establishment of radioimmunoassay system as a diagnostic tool for prostate disorders.

This study aimed to provide an easy and effective method for extraction and purification of prostate-specific antigen (PSA) from human seminal fluid with high quantity (14 mg) and high purity (98%). The obtained PSA was injected into rabbits for production of anti-PSA polyclonal antibody (titer 1/1000), labeled with radioactive iodine-125 for preparation of radioactive PSA tracer (purity 98 ± 1.8% and specific activity 64 ± 1.9 µCi/µg), and used in preparation of PSA standards. All prepared components can be used in PSA immunoassays specially radioimmunoassay (RIA) kit preparation as a diagnostic tool for prostatic diseases.

PLXNA3 Variant rs5945430 is Associated with Severe Clinical Course in Male Multiple Sclerosis Patients.

Multiple sclerosis (MS) exhibits sex bias in disease clinical course as male MS patients develop severe, progressive clinical course with accumulating disability. So far, no factors have been found associating with this sex bias in MS severity. We set out to determine the genetic factor contributing to MS male-specific progressive disease. This is an MS cross-sectional study involving 213 Kuwaiti MS patients recruited at Dasman Diabetes Institute. Exome sequencing was performed on 18 females and 8 male MS patients' genomic DNA. rs5945430 genotyping was performed using Taqman genotyping assay. Estradiol levels were determined by enzyme-linked immunosorbent assay. Exome analysis revealed a missense variant (rs5945430) in Plexin A3 (PLXNA3) gene (Xq28) associated with male-specific MS severity. Genotyping of 187 MS patients for rs5945430 confirmed the association of rs5945430G with increased disease severity in MS males (p = 0.013; OR 3.8; 95% CI 1.24-11.7) and disability (p = 0.024). Estradiol levels shown to effect PLXNA3 expression were lower in MS males compared to MS females, and they were lower than control rs5945430G males (p = 0.057), whereas MS females had similar estradiol levels to healthy females reducing the level of expressed PLXNA3 GG in MS females. PLXNA3 rs5945430G is associated with increased disease severity in MS male patients. Estradiol is a possible protective factor against the expression of rs5945430G in MS females.

DNA repair genes polymorphisms and risk of colorectal cancer in Saudi patients.

BACKGROUND AND STUDY AIMS: Polymorphisms in the DNA repair genes may influence individual capacity to repair DNA damage, which may be associated with increased genetic instability and carcinogenesis. Our aim was to evaluate the relation of genetic polymorphisms in 2 DNA repair genes, XPD Lys751Gln and XRCC1 (A399G), with colorectal cancer (CRC) susceptibility. We further investigated the potential effect of these DNA repair variants on clinicopathological parameters of CRC patients. PATIENTS AND METHODS: Both XPD and XRCC1 polymorphisms were characterised in one hundred CRC patients and one hundred healthy controls who had no history of any malignancy by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) method and PCR with confronting two-pair primers (PCR-CTPP), using DNA from peripheral blood in a case control study. RESULTS: Our results revealed that the frequencies of GG genotype of XRCC1 399 polymorphism were significantly higher in the CRC patients than in the normal individuals (p⩽0.03), and did not observe any association between the XPD Lys751Gln polymorphism and CRC risk. We found association between both XRCC1 A399G polymorphisms and histological grading of disease. CONCLUSION: Our results suggested that, XRCC1 gene is an important candidate gene for susceptibility to colorectal carcinoma.

Optimal primary surgical treatment for advanced epithelial ovarian cancer.

BACKGROUND: Ovarian cancer is the sixth most common cancer among women. In addition to diagnosis and staging, primary surgery is performed to achieve optimal cytoreduction (surgical efforts aimed at removing the bulk of the tumour) as the amount of residual tumour is one of the most important prognostic factors for survival of women with epithelial ovarian cancer. An optimal outcome of cytoreductive surgery remains a subject of controversy to many practising gynae-oncologists. The Gynaecologic Oncology group (GOG) currently defines 'optimal' as having residual tumour nodules each measuring 1 cm or less in maximum diameter, with complete cytoreduction (microscopic disease) being the ideal surgical outcome. Although the size of residual tumour masses after surgery has been shown to be an important prognostic factor for advanced ovarian cancer, it is unclear whether it is the surgical procedure that is directly responsible for the superior outcome that is associated with less residual disease. OBJECTIVES: To evaluate the effectiveness and safety of optimal primary cytoreductive surgery for women with surgically staged advanced epithelial ovarian cancer (stages III and IV).To assess the impact of various residual tumour sizes, over a range between zero and 2 cm, on overall survival. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2010, Issue 3) and the Cochrane Gynaecological Cancer Review Group Trials Register, MEDLINE and EMBASE (up to August 2010). We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. SELECTION CRITERIA: Retrospective data on residual disease from randomised controlled trials (RCTs) or prospective and retrospective observational studies which included a multivariate analysis of 100 or more adult women with surgically staged advanced epithelial ovarian cancer and who underwent primary cytoreductive surgery followed by adjuvant platinum-based chemotherapy. We only included studies that defined optimal cytoreduction as surgery leading to residual tumours with a maximum diameter of any threshold up to 2 cm. DATA COLLECTION AND ANALYSIS: Two review authors independently abstracted data and assessed risk of bias. Where possible, the data were synthesised in a meta-analysis. MAIN RESULTS: There were no RCTs or prospective non-RCTs identified that were designed to evaluate the effectiveness of surgery when performed as a primary procedure in advanced stage ovarian cancer.We found 11 retrospective studies that included a multivariate analysis that met our inclusion criteria. Analyses showed the prognostic importance of complete cytoreduction, where the residual disease was microscopic that is no visible disease, as overall (OS) and progression-free survival (PFS) were significantly prolonged in these groups of women. PFS was not reported in all of the studies but was sufficiently documented to allow firm conclusions to be drawn.When we compared suboptimal (> 1 cm) versus optimal (< 1 cm) cytoreduction the survival estimates were attenuated but remained statistically significant in favour of the lower volume disease group There was no significant difference in OS and only a borderline difference in PFS when residual disease of > 2 cm and < 2 cm were compared (hazard ratio (HR) 1.65, 95% CI 0.82 to 3.31; and HR 1.27, 95% CI 1.00 to 1.61, P = 0.05 for OS and PFS respectively).There was a high risk of bias due to the retrospective nature of these studies where, despite statistical adjustment for important prognostic factors, selection bias was still likely to be of particular concern.Adverse events, quality of life (QoL) and cost-effectiveness were not reported by treatment arm or to a satisfactory level in any of the studies. AUTHORS' CONCLUSIONS: During primary surgery for advanced stage epithelial ovarian cancer all attempts should be made to achieve complete cytoreduction. When this is not achievable, the surgical goal should be optimal (< 1 cm) residual disease. Due to the high risk of bias in the current evidence, randomised controlled trials should be performed to determine whether it is the surgical intervention or patient-related and disease-related factors that are associated with the improved survival in these groups of women. The findings of this review that women with residual disease < 1 cm still do better than women with residual disease > 1 cm should prompt the surgical community to retain this category and consider re-defining it as 'near optimal' cytoreduction, reserving the term 'suboptimal' cytoreduction to cases where the residual disease is > 1 cm (optimal/near optimal/suboptimal instead of complete/optimal/suboptimal).

The CTLA4 -819 C/T and +49 A/G dimorphisms are associated with Type 1 diabetes in Egyptian children.

BACKGROUND: Type 1 diabetes (T1D) is an organ-specific autoimmune disease characterized by T cell-mediated destruction of pancreatic islets. T cell proliferation is negatively regulated by cytotoxic lymphocyte antigen-4 (CTLA-4). CTLA-4 polymorphisms are associated with T1D in some but not all populations. AIMS: The study was conducted to investigate the association of the C-819T and A+49G single nucleotide polymorphisms (SNP) of CTLA-4 gene in T1D patients in the Egyptian population. METHODS: The association of the C-819T SNP in intron 1 and A+49G SNP in exon 1 of the CTLA-4 gene with T1D were investigated in 396 Egyptian patients 24 years old, with the same ratio of males to females in both groups. The diagnosis of T1D was made on the basis of ketoacidosis or ketosis with severe symptoms of acute onset at presentation and continuous dependence on insulin. Controls were negative for anti-GAD antibodies and were greater than 24 years of age. Genotyping was performed using single strand conformation polymorphism (SSCP), temperature gradient gel electrophoresis (TGGE), and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). RESULTS: The results demonstrated an association of the C-819T and A+49G SNPs in the CTLA-4 gene with T1D patients (P=0.0047) and (P=0.000575), respectively. Moreover, this association was stratified by gender and age to female patients with age at onset 0-5 years old (P=0.0186) and (P=0.00115) more than male patient with the age at onset 0-5 years old (P= 0.3120) and (P=0.345161), respectively. CONCLUSION: The results support an association of the C-819T and A+49G SNPs in the CTLA-4 gene with Egyptian children, specifically, females of onset age 0-5 years old.

Fourteen morphotypes of Entodinium ovumrajae (Ophryoscolecidae, Entodiniomorphida) found in the Dromedary camel of Egypt.

During a survey of the ciliate protozoal composition of the stomach contents of nine dromedary camels of Egypt, fourteen morphotypes of Entodinium ovumrajae, which has been considered as a species peculiar to camels, were found in six camels. Except for five morphotypes including one originally described as an independent species and its forms, these were newly detected. These morphotypes, divided into three groups, can be identified mainly by the morphology of their ectoplasmic processes. Each camel had on average, about five morphotypes of this species.
