RESUMEN

Background: Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related deaths worldwide, and especially in Egypt. Early diagnosis of HCC greatly improves the survival and prognosis of patients. Low sensitivity and specificity of alpha-fetoprotein (AFP) has led to the demand for novel biomarkers of HCC. The aim of the present study was to evaluate the validity of frizzled-7 (FZD7) and glypican-3 (GPC3) gene expression as potential biomarkers for HCC early diagnosis, and to investigate the association between FZD7 rs2280509 polymorphism and HCC risk. Materials and methods: Quantification of FZD7 and GPC3 gene expression by real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) assay, and genotyping FZD 7 (rs2280509 SNP) gene polymorphism using RT-PCR. Results: The current results revealed that FZD7 gene expression had a greater area under the curve (AUC) for identifying HCC than GPC3 gene expression and AFP levels. The combination of the three markers as a panel showed a better diagnostic performance with a greater AUC than any of the single markers alone (p < 0.05). The FZD7 rs2280509 polymorphism (CT) was found to be significantly associated with an increased risk of HCC. The CT genotype and T allele were significantly more prevalent in the HCC group compared to either the cirrhosis (p = 0.03) or control groups (p = 0.0009 and 0.002; respectively). Conclusion: FZD7 and GPC3 gene expressions have a complementary role in early HCC detection, with a greater diagnostic sensitivity and accuracy than AFP. In addition, FZD7 rs2280509 polymorphism is significantly associated with an increased risk of HCC in the Egyptian population.

RESUMEN

BACKGROUND: Up to date, a well-defined microRNAs (miRNAs) profile involved in hepatocellular carcinoma (HCC) pathogenesis remains indecisive. Thus, employing miRNAs for HCC diagnosis is demanded for early therapeutic interventions. We aimed to evaluate the usage of miRNAs set related to the SuperPath: miRNAs involved in DNA damage response pathway as effective biomarkers for HCV-related HCC diagnosis. RESULTS: The study enrolled 97 patients with HCV-related HCC, 84 with hepatitis C virus (HCV), 97 with liver cirrhosis (LC), and 84 healthy individuals. Serum miRNA-23a, miRNA-203, miRNA-100-5p, and miRNA-16 were quantified using qRT-PCR experiments, AFP and routine LFTs were estimated via standard techniques. Pathway enrichment analysis along with the construction of miRNAs regulatory network were performed. With respect to healthy individuals, miRNA-203, miRNA-100-5p, and miRNA-16 were significantly downregulated in HCC, HCV, and LC groups, while miRNA-23a showed significant upregulation (p < 0.001). miRNAs exhibited significant correlations with AFP, ALT, AST, and albumin. Also, elevated levels of miRNA-23a were recognized in patients with multiple focal lesions and/or lesion size > 5 cm. Additionally, the diagnostic performance of miRNA-23a expression level at a selected cut-off value of 3.99 overtakes AFP, while expressions of miR-203, miRNA-100-5p, and miRNA-16 represent poor diagnostic outcomes. CONCLUSIONS: Keeping in mind the individual variability and high level of heterogeneity in HCC, our data revealed the diagnostic value of miRNA-23a expression in HCV-related HCC patients. Further extra in silico HCC-specific microRNAs sets are demanded in diagnosis.

RESUMEN

BACKGROUND/AIMS: The aim of the present article was to compare stapled haemorrhoidectomy, and haemorrhoidal artery ligation with open haemorrhoidectomy with respect to the postoperative pain, symptom control, and manometric alterations. METHODOLOGY: Forty five patients with third or fourth-degree haemorrhoids were randomly classified into three groups; first group managed by stapled haemorrhoidectomy, second group managed by conventional haemorrhoidectomy and third group managed by Doppler guided haemorrhoidal artery ligation. (15 patients each) Preoperative and 12 weeks postoperative anorectal manometry were done for all patients. RESULTS: There was a significant difference of the operative time between stapled group and Milligan-Morgan group (p < 0.001) while no significant difference between stapled group and Doppler group. The pain scores were significantly higher in open group (p < 0.001) during the first 24 hours at the time of first motion and one week after operation. Postoperative control of prolapsed symptoms was significantly better with open diathermy haemorrhoidectomy than with stapled. The control of other symptoms was similar with regard to bleeding, pain, pruritus, and incontinence scores. Anorectal manometry showed a decrease in the maximum resting pressure and maximum squeeze pressure in all groups, but this decrease was only significant in the stapled haemorrhoidectomy group. CONCLUSIONS: Stapled and Doppler haemorrhoidectomy is as effective as conventional haemorrhoidectomy for the treatment of haemorrhoids, but with the exception of skin tag prolapse. There is a need for long-term follow-up for the changes in manometric parameters after haemorrhoidectomy.

RESUMEN

Scarpa's fascia preservation plays a great role in decreasing the volume of wound drainage and reducing seroma after abdominoplasty. This study aimed to assess the role of Scarpa's fascia preservation in patients with ventral hernias associated with abdominal wall deformity who underwent concomitant hernio-abdominoplasty in terms of early and late postoperative outcome and quality of life. METHODS: Patients with ventral hernia and abdominal wall deformity underwent combined hernio-abdominoplasty. Patients were randomly allocated to 1 of 2 equal groups: group I underwent Scarpa's fascia preserving hernio-abdominoplasty and group II underwent hernio-abdominoplasty with removal of Scarpa's fascia. Volume of drainage, time to remove drains, return to work, and complications were recorded. RESULTS: Fifty patients (49 female) were included to the study. Both groups had comparable operation time, pain score, and complication rate (24% versus 40%, P = 0.36). The mean total volume of postoperative drainage was significantly lower in group I than group II (686 ± 183.5 versus 1410.8 ± 371.6 ml; P < 0.0001). Group I had earlier drain removal (11.6 ± 1.9 versus 20.5 ± 4.2 days, P < 0.0001) and earlier return to work (16.4 ± 2.3 versus 23.3 ± 3.8 days, P < 0.0001) than group II. There were no recorded cases of hematoma or hernia recurrence after repair. CONCLUSION: Scarpa's fascia preservation in combined ventral hernia repair and abdominoplasty was associated with significantly lower volume of postoperative drainage, earlier removal of drains, and similar recurrence rate to hernio-abdominoplasty with removal of Scarpa's fascia.
