We report the case of a 7-year old girl presenting with sub-occlusive syndrome associated with acute paroxysmal abdominal pain at the level of the upper abdomen, vomiting and no evacuation of faeces. Physical examination showed discomfort with palpation of the upper abdomen. Abdominal ultrasound showed poorly limited intraperitoneal tissue formation without vascular features on doppler, exercising a mass effect on the neighborhood structures; mesenteric vessels were in their normal position. This mass on CT scan scorresponded to a well limited lipomatous formation exercising a mass effect on the caecum associated with volvulus of the small intestine...

BACKGROUND: Lymphatic malformations (LMs) are low-flow congenital lesions that consist of cysts of varying size. Sclerotherapy with intralesional bleomycin and OK-432 has been reported to yield dramatically beneficial results for this disorder. However, inflammation-related symptoms are often seen after treatment with these sclerosing agents. On the other hand, polidocanol (POL) is reportedly associated with fewer allergic and inflammatory reactions. Up to now, however, very few reports have documented the use of POL microfoam for treatment of LMs...

BACKGROUND: Overweight has been related to renal arteriolosclerosis and is able to modify intrarenal hemodynamics. Increasing evidences suggest an association between weight excess and primary glomerulonephritis (GN). The aim of this study was to evaluate the relationship between nutritional status and intrarenal arterial stiffness in primary GN associated to arteriolosclerosis. We have considered the glomerular diameter (GD) as morphological parameter in overweight and obese patients...

BACKGROUND: Limb tourniquets have been used extensively during modern Middle Eastern conflicts. Despite its undeniable successes, the combat applied tourniquet (C-A-T) has some shortfalls, principally its inability to reliably control lower limb bleeding when applied to the mid-thigh. We tested two tourniquets which may represent an improvement to the combat applied tourniquet; the tactical mechanical tourniquet and the tactical pneumatic tourniquet. METHODS: We recruited 12 healthy service personnel and applied the tactical mechanical tourniquet and tactical pneumatic tourniquet to both lower limbs in a randomly generated sequence...

BACKGROUND: Noninvasive continuous blood pressure (BP) measurement has become an evolving topic in the field of remote healthcare. The classical noninvasive BP measurement techniques provide spontaneous values of systolic and diastolic BP. On the other hand, intrusive type BP measurement techniques provide continuous values of systolic and diastolic BP. However, these techniques are very painful, cannot be used for long-term monitoring, and are obtainable only in an intensive care unit environment...

According to the latest report from the World Health Organization, an estimated 265,000 deaths still occur every year as a direct result of burn injuries. A widespread range of these deaths induced by burn wound happens in low- and middle-income countries, where survivors face a lifetime of morbidity. Most of the deaths occur due to infections when a high percentage of the external regions of the body area is affected. Microbial nutrient availability, skin barrier disruption, and vascular supply destruction in burn injuries as well as systemic immunosuppression are important parameters that cause burns to be susceptible to infections...

PURPOSE: Vitamin B deficiency has been identified as a risk factor for vascular events. However, the reduction of vascular events was not shown in large randomized controlled trials evaluating B-Vitamin therapy. There is an important requirement to develop sensitive biomarkers to be used as efficacy targets for B-Vitamin therapy as well as other dietary treatments and lifestyle regimes that are being developed. Carotid vessel-wall-plus-plaque thickness change (VWT-Change) measured from 3D ultrasound has been shown to be sensitive to atorvastatin therapies in previous studies...
