Supporting recovery from brain injury

2018

The beauty and intricacy of the human brain is unfortunately also mirrored by its vulnerability. Damage to the brain is typically permanent. Because cells of the adult brain, apart from rare exceptions, no longer divide, there is essentially no regrowth of damaged brain tissue. Acquired brain injury in the majority of cases occurs directly through traumatic events such as an accident involving a blow to the head or indirectly through interruption of the blood supply, namely a stroke. Brain injury is a major burden, with an estimated 1.7 million people in the United States suffering a traumatic brain injury and nearly 800,000 Americans suffering a stroke each year ( 1 , 2 ). However, current…

Clinical-anamnestic and instrumental data in outpatients suffering from venous disease

1995

The authors studied 200 consecutive outpatients with symptoms due to venous disease of the lower limbs. All the patients underwent anamnestic, clinical and instrumental evaluation (c.w. Doppler velocimetry and strain-gauge plethysmography). The results of this study showed that some anamnestic and clinical data are significantly related to venous disease detected by instrumental techniques. The superficial and deep vein hypertension were, instead, correlated to oral contraceptive use.

Digital image analysis of liver collagen predicts clinical outcome of recurrent hepatitis C virus 1 year after liver transplantation.

2011

Clinical outcomes of recurrent hepatitis C virus after liver transplantation are difficult to predict. We evaluated collagen proportionate area (CPA), a quantitative histological index, at 1 year with respect to the first episode of clinical decompensation. Patients with biopsies at 1 year after liver transplantation were evaluated by Ishak stage/grade, and biopsy samples stained with Sirius red for digital image analysis were evaluated for CPA. Cox regression was used to evaluate variables associated with first appearance of clinical decompensation. Receiver operating characteristic (ROC) curves were also used. A total of 135 patients with median follow-up of 76 months were evaluated. At 1…

A new mucosal propeller flap (Deep Lingual Artery Axial Propeller): The renaissance of lingual flaps

2015

BACKGROUND: Lingual flaps provide ideal mucosal coverage for intraoral defects but traditionally require two surgical stages. The authors present an axial mucosal propeller flap for single-stage intraoral reconstruction. The flap includes the mucosa of the lateral side of the tongue, islanded on the deep lingual vessels. METHODS: Between 2011 and 2013, 23 patients underwent intraoral mucosal reconstruction with a deep lingual artery axial propeller flap after cancer resection in the cheek (n = 16), floor of the mouth (n = 2), retromolar trigone (n = 2), hard palate (n = 2), and soft palate (n = 1). Mean defect size was 19.5 cm. Preoperative and postoperative intraoral function was evaluated…

LASCA and PPG imaging for non-contact assessment of skin blood supply

2013

Laser speckle contrast analysis (LASCA) offers a non-contact, full-field, and real-time mapping of capillary blood flow and can be considered as an alternative method to Laser Doppler perfusion imaging (LDPI). Photoplethysmography (PPG) is well known technique for assessment of skin blood pulsations that can be related to blood flow. In recent years several studies have been done on development of non-contact PPG imaging (PPGI). LASCA and PPGI techniques are simpler and cheaper compared with LDPI. LASCA technique has been implemented in several commercial instruments. However, these systems are still too expensive and bulky to be widely available. Several optical techniques have found new i…

Fistulae (Rectovaginal, Rectovesical)

1979

The clinical manifestations of a fistula — stool from the vagina, air from the urethra — are often difficult to recognize because the fistulous opening is hidden by the edematous and swollen mucosa. Larger defects occur particularly after radiation therapy and with Crohn’s disease.

Comparative study of the arterial and lacunary systems of the ventricular myocardium of elasmobranch and teleost fishes.

1983

The typical fish heart has a spongy trabeculated ventricular myocardium (spongiosa) supplied by the venous blood of the intertrabecular spaces (lacunae); hence it is called a "venous heart." However, in some fishes a more complex ventricular muscle is found (mixed type), in which the spongiosa is covered by an outer layer of densely arranged myocardial bundles (compacta). The compacta receives oxygenated blood from the coronary vessels. The objective of this study was to investigate relations between myoarchitecture and blood supply with an emphasis on the hitherto unexplored, putative vascular connections between the arterial and the lacunary circuits. Using histological methods combined w…
