ObjectiveTo investigate the effectiveness of anterolateral femoral flap in combination with fascia lata grafting in repair of large Achilles tendon and skin defects.MethodsThe clinical data of 18 patients with large Achilles tendon and skin defects repaired with anterolateral femoral flap in combination with fascia lata grafting between January 2018 and January 2019 were retrospectively reviewed. There were 14 males and 4 females; age ranged from 32 to 57 years (mean, 42.1 years). There were 9 cases of postoperative infection of Achilles tendon rupture, 1 case of traffic accident injury, and 8 cases of combined infection of skin and Achilles tendon defects after heel trauma. The length of Achilles tendon defect was 4-8 cm, with an average of 5.6 cm; the range of the skin defect was 14 cm×3 cm to 20 cm×5 cm. Flap survival was observed, and ankle function recovery was evaluated according to McComis functional assessment criteria, and dorsal extension and plantar flexion mobility of the affected limb were measured at last follow-up and compared with those of the healthy side.ResultsEighteen cases were followed up 8-24 months, with an average of 16.7 months. All the flaps survived after operation, the flaps were soft and elastic, and the incisions healed by first intention. At last follow-up, 15 cases were excellent, 2 cases were good, and 1 case was acceptable according to McComis functional evaluation criteria, with an excellent and good rate of 94.4%. The two-point discrimination of the heel posterior region of the affected foot was 4-7 mm, with an average of 5.32 mm. The heel-raise test was negative. The dorsiflexion range of the affected side was (21.55±1.26)°, which was significantly different from that of the healthy side (25.23±1.45)° (t=8.128, P=0.000); the plantar flexion of the affected side was (44.17±1.52)°, which was not significantly different from that of the healthy side (46.13±1.31)° (t=0.444, P=0.660).ConclusionThe application of anterolateral femoral flap in combination with fascia lata grafting for the repair of large Achilles tendon and skin defects can achieve good effectiveness.
ObjectiveTo explore the independent factors related to clinical severe events in community acquired pneumonia patients and to find out a simple, effective and more accurate prediction method.MethodsConsecutive patients admitted to our hospital from August 2018 to July 2019 were enrolled in this retrospective study. The endpoint was the occurrence of severe events defined as a condition as follows intensive care unit admission, the need for mechanical ventilation or vasoactive drugs, or 30-day mortality during hospitalization. The patients were divided into severe event group and non-severe event group, and general clinical data were compared between two groups. Multivariate logistic regression analysis was performed to identify the independent predictors of adverse outcomes. Receiver operating characteristic (ROC) curve was constructed to calculate and compare the area under curve (AUC) of different prediction methods.ResultsA total of 410 patients were enrolled, 96 (23.4%) of whom experienced clinical severe events. Age (OR: 1.035, 95%CI: 1.012 - 1.059, P=0.003), high-density lipoprotein (OR: 0.266, 95%CI: 0.088 - 0.802, P=0.019) and lactate dehydrogenase (OR: 1.006, 95%CI: 1.004 - 1.059, P<0.001) levels on admission were independent factors associated with clinical severe events in CAP patients. The AUCs in the prediction of clinical severe events were 0.744 (95%CI: 0.699 - 0.785, P=0.028) and 0.814 (95%CI: 0.772 - 0.850, P=0.025) for CURB65 and PSI respectively. CURB65-LH, combining CURB65, HDL and LDH simultaneously, had the largest AUC of 0.843 (95%CI: 0.804 - 0.876, P=0.022) among these prediction methods and its sensitivity (69.8%) and specificity (81.5%) were higher than that of CURB65 (61.5% and 76.1%) respectively.ConclusionCURB65-LH is a simple, effective and more accurate prediction method of clinical severe events in CAP patients, which not only has higher sensitivity and specificity, but also significantly improves the predictive value when compared with CURB65.
