PACs are common in MDCT and should not be misdiagnosed as pneumomediastinum. It should be kept in mind that PACs may be associated with COPD.

In this study, the presence of AKI was found to be an independent risk factor in the development of in-hospital mortality according to all classification systems (RIFLE, AKIN, CK, and KDIGO) in critically traumatic patients followed in ICU, and the compatibility between RIFLE, AKIN, and KDIGO was the highest among the classification systems.

Objective: The purpose of this study was to evaluate the patients with acute amitriptyline poisoning and investigate predictive factors for the development of life-threatening complications. Methods: Demographics, clinical, laboratory, and electrocardiographic (ECG) findings of 250 patients were evaluated retrospectively. Predictive parameters for the development of serious complications were studied. Results: Median age of patients was 14.6 years, of which, 70% of patients were female and 66% were in pediatric age group. The most common pathological clinical finding and laboratory abnormality were alteration of consciousness and hyponatremia. The rate of convulsive seizure, arrhythmia, and respiratory depression were 17 (6.8%), 16 (6.4%), and 11 (4.4%), respectively. These complications were more seen in pediatric patients than adults (15.8% and 1.2%). The incidence of hyponatremia was more in pediatric patients and severe poisoning groups (38.8 and 53.4%, respectively). The levels of amitriptyline and nortriptyline were significantly higher in the group with complications than the group without complications ( p < 0.05). All adult patients were discharged with good prognosis. In pediatric age group, one patient was discharged with severe neurological sequelae and one patient died. QRS duration >100 ms, long corrected QT duration interval, and low Glasgow Coma Score (GCS) at admission were identified as independent risk factors for the development of life-threatening complications (odds ratio: 69.4, 1.9, and 1383, respectively; p < 0.05). Conclusion: Amitriptyline poisoning may be associated with life-threatening complications, especially in pediatric age group and in patients with hyponatremia. Low GCS, presence of hyponatremia, high serum drug levels, and pathological ECG findings on admission may be helpful in predicting the development of complications and poor prognosis.

Objectives To assess the feasibility of ultrasound and shear wave elastography (SWE) in the diagnosis of breast cancer–related lymphedema. Methods Forty‐one patients with a history of unilateral breast surgery and axillary dissection or sentinel lymph node excision were included in this prospective study. The patients were classified as having normal findings, latent lymphedema, and clinical lymphedema on the basis of a physical examination, lymphedema index scores, and limb circumference measurements. The thickness and stiffness of the cutaneous and subcutaneous tissue of the forearm and arm were measured by ultrasound and SWE. The thickness and stiffness of the cutaneous and subcutaneous tissue of the affected limb and contralateral limbs of the normal, latent lymphedema, and clinical lymphedema groups were compared. Results The mean age ± SD of the 41 patients was 55.42 ± 10.12 years. There were 15 patients with normal findings, 10 with latent lymphedema, and 16 with clinical lymphedema. In the latent lymphedema group, the thickness measurements of the cutaneous tissue of the affected forearm and the cutaneous and subcutaneous tissue of the affected arm were significantly greater than those of the contralateral forearm and arm (P = .034; P = .022; and P = .002, respectively), and the stiffness measurements of the cutaneous and subcutaneous tissue of the affected forearm were significantly greater than those of the contralateral forearm (P = .011; and P = .002). In the clinical lymphedema group, the thickness and stiffness measurements of the cutaneous and subcutaneous tissue of the affected forearm and arm were significantly greater than those of the contralateral limb (P < .001–P = .032). Conclusions Ultrasound and SWE are effective for diagnosing breast cancer–related lymphedema even at a latent stage.
