[Soft muscle obvious mobile sarcoma. A written report of 3 cases].
BACKGROUND Mirizzi syndrome is an uncommon complication of longstanding gallstone disease. Pre-operative diagnosis is challenging, and to date, there is no consensus on the standard management for this condition. Until recently open cholecystectomy was the standard of care for type II Mirizzi syndrome (McSherry classification). The objective of this study was to assess the incidence and management of type II Mirizzi syndrome in patients with proven or suspected choledocholithiasis undergoing laparoscopic common bile duct (CBD) exploration and present our experience in the laparoscopic management of this rare condition over the last 21 years. METHODS Prospective data collection of eleven cases of type II Mirizzi syndrome amongst a series of 425 laparoscopic bile duct explorations was performed between 1998 and 2019. Demographic, clinical, diagnostic, intra-operative, and post-operative data were recorded. RESULTS The incidence of type II Mirizzi syndrome was 2.6% in 425 laparoscopic CBD explorations. All operations were completed laparoscopically with closure of the defect over a decompressed CBD (T-tube n = 3, antegrade stent n = 5, transcystic drain n = 2), and in one case a non-drained duct was closed with Endoloop. Stone clearance rate was 100% (11 cases). In two patients the transinfundibular approach was used in conjunction with holmium laser lithotripsy to enable choledochoscopy and successful stone clearance. Three patients were complicated in the post-operative period with bile leak (n = 2) and lower respiratory tract infection (n = 1). An incidental gallbladder carcinoma was found in one patient. CONCLUSION Laparoscopic management of type II Mirizzi syndrome is feasible and safe when performed by experienced laparoscopic foregut surgeons. Laparoscopy and choledochoscopy can be combined with novel approaches and techniques to increase the likelihood of treatment success.BACKGROUND AND AIMS Previous studies have suggested that aggressive hydration with lactated ringer solution are one of the protective factors in preventing post endoscopic retrograde cholangiopancreatography (post-ERCP). We conducted a systematic review and meta-analysis to examine the efficacy aggressive hydration with lactated Ringer solution in preventing PEP. METHODS All published and unpublished articles on aggressive hydration with lactated ringer solution in those underwent ERCP procedure for any reasons were screened for eligibility. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. This paper doesn't need the IRB approval. RESULTS Seven RCTs met the inclusion criteria. Meta-analysis indicates that aggressive hydration with lactated Ringer solution were associated with lower PEP rate.[odds ratio (OR) 0.29; 95% confidence interval (CI) 0.18-0.48]; lower incidence of hyperamylasemia (OR 0.49; 95% CI 0.35, 0.69) and lower risk of pain (OR 0.28; 95% CI 0.10-0.81). The association between aggressive hydration with lactated Ringer solution and incidence of moderate severity PEP were unclear (OR 0.57; 95% CI 0.22, 1.45). Sensitivity analyses also showed that omitting 1 study from analysis of PEP rate could reduce the heterogeneity but did not change the conclusion of this meta-analysis. A cumulating meta-analysis was performed statistically which showed a stable result of overall incidence of PEP. CONCLUSIONS Aggressive hydration with lactated Ringer solution was a protective factor in reducing the overall incidence of PEP, hyperamylasemia and risk of abdominal pain.BACKGROUND Inorganic phosphate (Pi) is an essential mineral for human. Hypophosphatemia and hyperphosphatemia cause rickets/osteomalacia and ectopic calcification, respectively, indicating that serum Pi level needs to be regulated. Fibroblast growth factor (FGF) 23 is a principal hormone to regulate serum Pi level. FGF23 is produced by the bone, especially by the osteoblasts and osteocytes, and works by binding to FGF receptor (FGFR) 1c and α-Klotho complex in the kidney. FGF23 reduces serum Pi level by inhibiting both renal phosphate reabsorption and intestinal phosphate absorption via reduction of serum 1,25-dihydroxyvitamin D level. It has been unclear how the bone senses changes of serum Pi level and how the bone regulates the production of FGF23. RECENT FINDINGS Our recent results indicate that the post-translational modification of FGF23 protein through a gene product of GALNT3 is the main regulatory mechanism of enhanced FGF23 production by high dietary Pi. Furthermore, high extracellular Pi directly activates FGFR1 and its downstream intracellular signaling pathway regulates the expression level of GALNT3. CONCLUSIONS We propose that FGFR1 works as a Pi-sensing receptor in the regulation of FGF23 production and serum Pi level. There is a negative feedback system, which is a basic mechanism of endocrine regulation, in the regulation of serum Pi involving FGFR1, and FGF23. These findings may lead to the development of new therapeutic methods to treat diseases caused by abnormal Pi level.Radix Paeoniae Alba is widely used in Chinese traditional medicine to treat various diseases such as gastrointestinal disorders, immunomodulatory, cancer, and other diseases. In this paper, a novel acidic polysaccharide RPAPS purified from Radix Paeoniae Alba was evaluated for its structural features and potential of immunomodulatory and antioxidant activities. RPAPS (molecular weight 1.0× 105 Da) was mainly composed of α-(1 → 4)-Glcp, α-Arap, α-Galp, α-Rhap, β-D-Glcp, α-(1 → 6)-linked Glcp and GalA. Immunological tests indicated that RPAPS could improve RAW264.7 phagocytic activity and LPS-induced splenocyte proliferation. For antioxidant activities, RPAPS showed reducing power and DPPH scavenging activity in dose dependent. Moreover, RPAPS could significantly protect the PC12 cells from H2O2 damage. These data implied polysaccharides RPAPS had the potential to be novel natural antioxidative and immunopotentiating agents for using in functional foods or medicine.The incidence of cancer in children with intellectual disability has been poorly documented. We report our experience of treating children and adolescents with cancer and intellectual disability (40 patients), from 2004 to 2018. A treatment-sparing approach was adopted for 6 patients with severe intellectual impairment to minimize toxicity a child with postpartum asphyxia and medulloblastoma did not receive radiotherapy; 1 patient with mitochondrial encephalopathy and a testicular germ cell tumor did not receive bleomycin and lung metastasectomy; 2 patients (1 with Down + West syndrome + Wilms tumor (WT) and 1 with Denys-Drash syndrome + WT) did not receive vincristine; 1 child with corpus callosum agenesis and anaplastic ependymoma did not receive chemotherapy; 1 child with structural chromosomal aberrations and a primitive neuro-ectodermal tumor received personalized chemotherapy. Heminephrectomy was performed in 4 patients with WT to preserve their kidney function. https://www.selleckchem.com/products/ca-170.html We found no statistically significant correlation between relapse or mortality rates and the use of a treatment-sparing approach.
