Identification of a de novo MAP2K1 gene variant in an affected patient with Cardio-facio-cutaneous syndrome / 中华医学遗传学杂志

OBJECTIVE@#To explore the genotype-phenotype correlation of Cardio-facio-cutaneous syndrome (CFCS) caused by MAP2K1 gene variants.@*METHODS@#Genomic DNA was extracted from peripheral blood sample from a child patient and his parents. Whole exome sequencing (WES) was carried out for the patient. Suspected variant was verified by Sanger sequencing.@*RESULTS@#The patient was a 1-year-8-month old Chinese male who manifested short stature, psychomotor retardation, relative macrocephaly, distinctive facial features, and congenital heart disease. WES test revealed a heterozygous missense c.389A>G (p.Tyr130Cys) variant in the MAP2K1 gene. Sanger sequencing has confirmed the variant as de novo. According to ACMG/AMP guidelines, the variant was classified as pathogenic.@*CONCLUSION@#Compared with previously reported CFCS cases due to MAP2K1 variants. The patient showed obvious behavioral problems, good appetite and tricuspid regurgitation, which may to be novel features for CFCS.

A Case Report of Xanthogranulomatous Cystitis.

Xanthogranulomatous cystitis (XC) is a chronic granulomatous inflammation with rare incidence. Herein, we report a 62-year-old female whose cystoscopic biopsy showed chronic inflammation accompanied with acute episode of inflammation. According to CT scan, pathology of the lesion could not rule out bladder carcinoma. Thus, partial cystectomy was done. But post-operatory pathological examination of the specimen was finally demonstrated Xanthogranulomatous cystitis. To the best of our knowledge, the present case of XC is the 28th to be reported in the world literature.

Value of suprapubic cystostomy in bipolar transurethral resection of the prostate for benign prostatic hyperplasia below 80 gram / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the perioperative benefit of suprapubic cystostomy in bipolar transurethral resection of the prostate (B-TURP) for treatment of benign prostatic hyperplasia (BPH) below 80 g.</p><p><b>METHODS</b>This retrospective study was conducted in patients undergoing B-TURP for BPH below 80 g, who were stratified with respect of suprapubic cystostomy in B-TURP. The end points including the safety, efficiency, complications and nursing care were compared between the two groups.</p><p><b>RESULTS</b>A total of 585 patients were enrolled, including 366 in cystostomy group and 219 in non-cystostomy group. The two groups showed similar postoperative reduction of serum sodium (0.06 vs 0.54 mmol/L, P>0.05), hematocrict (2.44% vs 2.89%, P>0.05), and blood hemoglobin concentration (9.62 vs 10.42 g/L, P>0.05), with comparable weight of resected prostate (42.50 vs 43.76 g, P>0.05). The operation time was significantly longer in cystostomy group than in non-cystostomy group (90.75 vs 76.28 min, P<0.05), but the rate of blood transfusion and incidences of postoperative fever and catheter blocking were comparable between the two groups. Compared with the non-cystostomy group, cystostomy group had significantly longer time for bladder washing (3.15 vs 2.57 days, P<0.05), catheter indwelling time (5.19 vs 4.15 days, P<0.05), and hospital stay after the operation (7.36 vs 5.65 days, P<0.05).</p><p><b>CONCLUSIONS</b>In B-TURP for BPH below the weight of 80 g, suprapubic cystostomy is associated with a longer time for operation, bladder washing, catheter indwelling and postoperative hospital stay, and thus provides no obvious benefits for the patients.</p>
