This study confirms that MSAP flap is thinner than ALT and the results correlate with BMI. Therefore, MSAP flap can be considered a good alternative to ALT, to avoid bulk, in reconstruction of shallower soft tissue defects.
Background: Troponin levels may be elevated in COVID-19 infection. The aim of this study was to the explore relation between troponin levels and COVID-19 severity. Materials & methods/Results: One hundred and forty consecutive patients with COVID-19 pneumonia were included. Diagnosis of COVID-19 pneumonia was based on positive chest computed tomography (CT) findings. Quantitative PCR test was performed in all patients. Only 74 patients were quantitative PCR-positive. Twenty four patients had severe CT findings and 27 patients had progressive disease. These patients had significantly lower albumin and higher ferritin, D-dimer, lactate dehydrogenase, C-reactive protein, and high-sensitivity cardiac troponin I (hs-cTnI). Conclusion: COVID-19 patients with severe CT findings and progressive disease had higher hs-cTnI levels suggesting the use of hs-cTnI in risk stratification.
Background During a subcutaneous mastectomy, nerves are severed and patients lose sensation on the breast skin. The aim of this study is to investigate factors that have impact on the sensation of the mastectomy flaps and patients' own perception regarding overall breast skin sensation.
Patients and Methods Patients who have undergone skin sparing or nipple sparing mastectomy with immediate reconstruction with either an implant or autologous tissue were included. Sensory assessment was performed at least 12 months after surgery using Semmes–Weinstein monofilaments (Aesthesio, San Jose, CA). The breast envelope was divided into four quadrants, and one measurement from each quadrant was recorded. Patients were also asked to fill out a questionnaire before the examination.
Results A total of 59 breasts in 40 women were examined. In lower medial quadrant, significantly more patients reported “no sensation” in the radiated group than the nonradiated group. In upper medial quadrant and lower lateral quadrant, patients with NSM reported better sensation than patients with skin sparing mastectomy (SSM).
Conclusion Vascularized tissue did not improve sensory recovery. There was no relationship between sensation and the preoperative cup size and the number of revision surgeries. Irradiation was associated with higher sensory thresholds in lower medial quadrant. Nipple sparing mastectomy was associated with lower sensory thresholds in two quadrants compared to SSM. Independent of all variables none of the patients reported normal sensation.
ZA infusion did not affect P wave dispersion both at the immediate post-infusion period and 1 month after infusion. QT values were significantly increased early after ZA infusion; however, there were no significant differences in parameters reflecting disparity of ventricular recovery times and transmural dispersion of ventricular repolarization. Based on these observations, it may be suggested that ZA infusion did not have any short- or long-term effect on any parameter that might be associated with the tendency for atrial fibrillation or ventricular arrhythmias.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
