First report of Ancylostoma tubaeforme in Persian Leopard (Panthera pardus saxicolor)

Ancylostoma tubaeforme was originally described as a separate species parasitizing the cat. The adults of A. tubaeforme are 7 to 12 mm long. A. tubaeforme can be differentiated from the adults of A. braziliense and A. ceylanicum by the presence of three teeth. Here we describe the first report of A. tubaeforme in a Persian young female leopard, 2–3 years old, with head and trunk length 120 centimeters, length of tail 98 centimeters and body weight 35 kilograms.     

Tokyo Guidelines 2018: diagnostic criteria and severity grading of acute cholangitis (with videos)

Although the diagnostic and severity grading criteria on the 2013 Tokyo Guidelines (TG13) are used worldwide as the primary standard for management of acute cholangitis (AC), they need to be validated through implementation and assessment in actual clinical practice. Here, we conduct a systematic review of the literature to validate the TG13 diagnostic and severity grading criteria for AC and propose TG18 criteria. While there is little evidence evaluating the TG13 criteria, they were validated through a large‐scale case series study in Japan and Taiwan. Analyzing big data from this study confirmed that the diagnostic rate of AC based on the TG13 diagnostic criteria was higher than that based on the TG07 criteria, and that 30‐day mortality in patients with a higher severity based on the TG13 severity grading criteria was significantly higher. Furthermore, a comparison of patients treated with early or urgent biliary drainage versus patients not treated this way showed no difference in 30‐day mortality among patients with Grade I or Grade III AC, but significantly lower 30‐day mortality in patients with Grade II AC who were treated with early or urgent biliary drainage. This suggests that the TG13 severity grading criteria can be used to identify Grade II patients whose prognoses may be improved through biliary drainage. The TG13 severity grading criteria may therefore be useful as an indicator for biliary drainage as well as a predictive factor when assessing the patient's prognosis. The TG13 diagnostic and severity grading criteria for AC can provide results quickly, are minimally invasive for the patients, and are inexpensive. We recommend that the TG13 criteria be adopted in the TG18 guidelines and used as standard practice in the clinical setting.

Bioresorbable vascular scaffold to treat in‐stent restenosis: Single‐center experience

Aims

The management of patients with in‐stent restenosis (ISR) is still a major clinical challenge even in the era of drug‐eluting stents (DES). Recent studies have demonstrated acceptable clinical outcomes for the everolimus‐eluting bioresorbable vascular scaffold (BVS) ABSORB? in patients with stable coronary artery disease but data are scarce on its use in patients with ISR. We report the long‐term results of our preliminary experience with this novel approach at our institution.

Methods and Results

We investigated the safety and efficacy of BVS implantation to treat ISR. 34 consecutive patients (37 lesions) underwent PCI for ISR with BVS implantation between May 2013 and June 2015 at our institution and were included in the current analysis. Follow‐up was available in 91.9% of the patients. Mean follow‐up period was 801.9 ± 179 days. One patient had definite scaffold thrombosis (ScT) 2 months after stent implantation which was treated with DES. Five patients (six lesions) experienced target lesion revascularization (TLR). The composite endpoint rate of TLR, ScT, myocardial infarction, and death occured in 6/37 lesions at follow‐up (16.2%).

Conclusions

These real‐world data using BVS in patients with ISR demonstrates that ISR treatment with ABSORB? BVS is feasible but could have slightly higher target lesion failure rates as compared to DES. This proof of concept could be hypothesis‐generating for larger randomized controlled studies.
