The patients were assigned to the complicated acute appendicitis group (Group C) based on the preoperative imaging findings (periappendiceal abscess formation or significant periappendiceal fat tissue contamination in ultrasonography and computed tomography), intraoperative exploration findings (presence of gangrenous appendicitis, perforation or abscess formation), and pathological examination findings (acute phlegmonous appendicitis, acute gangrenous appendicitis or acute perforated appendicitis).

The patients were assigned to the uncomplicated acute appendicitis group (Group UC) based on the increased diameter and wall thickness of the appendix and detection of minimal contamination in the surrounding fat tissue in the imaging tests; the presence of edema and the absence of gangrene, perforation or abscess in the the exploratory surgery of appendix, and confirmation of the diagnosis of acute appendicitis by the pathological examination findings

Sequential Compression Devices Effect on Fibrinolysis in Plastic Surgery Outpatients

The Effect of Intraoperative Sequential Compression Devices on Fibrinolysis in Plastic Surgery Outpatients: A Randomized Trial

Prospective, randomized, controlled study.

Two sequences of ten healthy volunteers each will be performed :
During the first sequence, a biopsy of the gluteal area and another of the surrounding nail area of a finger will be sampled.Then, the cutaneous blood flux of the hand will be recorded at rest and during cooling and warming periods.
During the second sequence, two other biopsies of the surrounding nail area of two other fingers will be sampled.

Two sequences of ten primary Raynaud's syndrome each will be performed :
During the first sequence, a biopsy of the gluteal area and another of the surrounding nail area of a finger will be sampled.Then, the cutaneous blood flux of the hand will be recorded at rest and during cooling and warming periods.
During the second sequence, two other biopsies of the surrounding nail area of two other fingers will be sampled.

Subjects will receive a new pair of diabetic shoes with BOA shoelace closure and a pair of AVEX Footbeat insoles, which include a micro-mobile compression pump. The entire system is named 'intervention shoes' for simplicity. They will be instructed to wear the intervention shoes on daily basis for 4 weeks for duration of at least 4 hours per day.

Avex Footbeat: Subjects will receive diabetic shoes equipped with Boa Technology shoelace system and Footbeat compression insoles, which for simplicity will be named intervention shoes. All participants will be asked to wear the intervention shoes for duration of 4-weeks on daily basis (minimum 4 hours per day). Daily use of the intervention shoes will be assumed to improve balance, mobility, plantar sensation, lower extremity edema, and lower extremity skin perfusion.

Region of Enrollment

Balance will be quantified by measuring body sway in medial-lateral direction using a validated wearable sensors technology (Balansens, Biosensics LLC) and body sway change after 4-weeks of daily use of AVEX Footbeat will be assessed compare to baseline. Th unit of measurement is cm.

Change in Balance From Baseline to 4 Weeks

Skin perfusion was quantified using Skin Perfusion Pressure Test (SPP) at the lower extremities at baseline and at 4-week (end point). The measurement of SPP was done using a device called Sensilase PAD-IQ (VASAMED). The unit of measurement is mmHg.

Change in Skin Perfusion From Baseline to 4 Weeks

Edema will be measured by traditional circumference change of ankle. The unit of measurement is cm.

Change in Lower Extremity Edema From Baseline to 4 Weeks

The change in plantar sensation after 4-weeks use of AVEX Footbeat will be assessed using vibratory perception threshold (VPT) test. The unit of this measurement is volt.

Change in Plantar Sensation From Baseline to 4-week

The change in stride velocity was quantified by gait speed measured using a validated wearable sensor (LEGSys, Biosensics, LLC). The unit of measurement is meter per second (m/s)
