ABSTRACT

We have evaluated the diagnostic performance of immunochromatographic point-of-care tests (POCT) for the detection of rotavirus, coronavirus, Escherichia (E.) coli F5, Cryptosporidium (C.) parvum, Clostridium (Cl.) perfringens and Giardia (G.) intestinalis in fresh and thawed faecal samples from calves aged up to six months with diarrhoea. We performed POCTs to detect rotavirus, coronavirus, E. coli F5, C. parvum, Cl. perfringens and G. intestinalis on fresh samples in a field study and re-evaluated the performance for C. parvum, Cl. perfringens and G. intestinalis using thawed samples. We calculated the performance based on the results of the reference methods, which were RT-qPCR for the detection of rota- and coronavirus and bacteriological culturing and PCR to detect E. coli F5 and Cl. perfringens a and ss2 toxins. C. parvum was detected by phase-contrast microscopy and G. intestinalis by immunofluorescence microscopy. We collected 177 faecal samples from diarrhoeic calves. We found good performance for the POCT targeting rotavirus (sensitivity (SE)=92.9%;specificity (SP)=95.6%) and C. parvum (SE=63.3%;SP=96.2%). For E. coli F5, the number of true positive samples (n=1) was too low to evaluate the performance. The POCT to detect coronavirus gave a poor performance (SE=3.3%;SP=96.6%) and the POCT to detect Cl. perfringens a moderate performance (SE=52.8%;SP=78.2%). G. intestinalis POCT showed a higher sensitivity to immunofluorescence microscopy in thawed than in fresh faecal samples (SE=43.9% versus SE=29.2%). There are substantial differences in diagnostic performance between the commercially available immunochromatographic POCTs. Still, POCT can make a valuable contribution to the diagnosis and prevention of calf diarrhoea.

ABSTRACT

Introduction: The objective was to investigate the feasibility, safety, efficacy, and patient acceptability of performing mini-PCNL as a day case procedure. To our knowledge, this is the first reported series in the UK. Method Mini-PCNL data was prospectively collected between April- December 2021. Renal access was achieved by the operating surgeon under fluoroscopic guidance in the prone position. The MIP-M system (Karl Storz, Germany) was used. Stones were fragmented using holmium LASER and retrieved by the Vortex effect and basket. Drainage was via a 6 Fr antegrade stent or 10 Fr nephrostomy tube. Patients suitable for same day discharge were identified using defined preoperative selection criteria. Stone related outcomes, duration of surgery, length of stay, readmission rate and complications were recorded. Results: Fifty patients underwent mini-PCNL (34 male,16 female) with a mean age of 60 years. Mean stone size was 24 mm with a mean operating time of 90 minutes. Twenty patients were suitable for same day discharge. Thirty patients stayed overnight (15 for social reasons, 13 for medical comorbidities and 2 for complications). We recorded 1 case of post-operative sepsis and bleeding requiring embolization. The readmission rate was 0% and 85% were stone free on post-operative CT KUB. Conclusion: Our study shows that day case mini-PCNL is safe, feasible and acceptable in selected group of patients. With the ever-rising pressures on stone services to drive efficiency particularly pertinent with the COVID pandemic, day case mini-PCNL represents an ideal therapeutic option in suitable cases.
