Under the conditions of this study, the PPV index was not shown to be a reliable predictor of FR during OLT. Further studies are warranted to elucidate the role of this and other dynamic indexes in this specific setting.

Objective: To evaluate the clinical diagnosis of pelvic inflammatory disease (PID) compared with the diagnosis of PID made by laparoscopy, endometrial biopsy, transvaginal ultrasound, and cervical and endometrial cultures. Study design: A diagnostic performance test study was carried out by cross-sectional analysis in 61 women. A group presenting PID (n = 31) was compared with a group (n = 30) presenting another cause for non-specific lower abdominal pain (NSLAP). Diagnosis provided by an evaluated method was compared with a standard diagnosis (by surgical findings, histopathology, and microbiology). The pathologist was unaware of the visual findings and presumptive diagnoses given by other methods. Results: All clinical and laboratory PID criteria showed low discrimination capacity. Adnexal tenderness showed the greatest sensitivity. Clinical diagnosis had 87% sensitivity, while laparoscopy had 81% sensitivity and 100% specificity; transvaginal ultrasound had 30% sensitivity and 67% specificity; and endometrial culture had 83% sensitivity and 26% specificity. Conclusions: Clinical criteria represent the best diagnostic method for discriminating PID. Laparoscopy showed the best specificity and is thus useful in those cases having an atypical clinical course for discarding abdominal pain when caused by another factor. The other diagnostic methods might have limited use.

Transient postoperative coagulation abnormalities frequently occur in living liver donors, particularly after right liver resection. Usually, this coagulopathy is diagnosed by alterations in conventional coagulation tests (CCTs) such as the international normalized ratio (INR) of the prothrombin time. However, recent studies using other methods of coagulation monitoring have suggested that postoperative hypercoagulability may also occur in living donors. The rotational thromboelastometry (ROTEM) system is a coagulation monitor based on the viscoelastic properties of blood. The use of ROTEM for perioperative coagulation monitoring in the setting of living liver donors has not been reported. We evaluated the perioperative coagulation profile as assessed by ROTEM in 16 consecutive donors who underwent either right or left liver resection at our institution. ROTEM analysis and CCTs were performed at the baseline (before skin incision) and on postoperative days 1 and 3. According to the CCTs, hypocoagulability was revealed in all but 1 (left liver) donor. The INR was highest on postoperative day 1 [median ¼ 1.67 (interquartile range ¼ 1.37-1.8)]. In contrast, all donors had a normal coagulation profile as assessed by the ROTEM system throughout the study period. In conclusion, this study showed the disagreement between the CCTs and the ROTEM system, as no significant coagulation abnormalities could be revealed with the latter method during the study period. Further studies are needed to confirm the role of the ROTEM system as a perioperative coagulation monitor in this setting and ultimately its influence on the outcome of living donors.
