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.
Clinical parameters of implants placed in healed sites using flapped and flapless techniques: A systematic review
2017
Background: Dental implant placement using flapless surgery is a minimally invasive technique that improves blood supply compared with flapped surgery. However, the flapless technique does not provide access to allow bone regeneration. Objectives: The aim of this systematic review was to evaluate the clinical parameters following implant surgery in healed sites, using two procedures: flapped vs. flapless surgery. Material and Methods: A detailed electronic search was carried out in the PubMed/Medline, Embase and Cochrane Library databases. The focused question was, “How do flapped and flapless surgical techniques affect the clinical parameters of dental implants placed in healed sites?”. Al…
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.

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…
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…
Low-Frequency Electrical Stimulation Increases Muscle Strength and Improves Blood Supply in Patients With Chronic Heart Failure
2005
This study was designed to evaluate the effects of low-frequency electrical stimulation (LFES) on muscle strength and blood flow in patients with advanced chronic heart failure (CHF).Patients with CHF (n=15; age 56.5 +/- 5.2 years; New York Heart Association III - IV; ejection fraction 18.7 +/- 3.3%) were examined before and after 6 weeks of LFES (10 Hz) of the quadriceps and calf muscles of both legs (1 h/day, 7 days/week). Dynamometry was performed weekly to determine maximal muscle strength (F(max); N) and isokinetic peak torque (PT(max); Nm); blood flow velocity (BFV) was measured at baseline and after 6 weeks of LFES using pulsed-wave Doppler velocimetry of the right femoral artery. Si…
Anastomoses (Ileorectal; Colorectal)
1979
With disease processes that involve the large bowel but leave the rectum free (Crohn’s disease, diverticulitis, neoplasms), a surgical procedure used for their treatment will result in an anastomosis that may be seen during rectoscopy. During the postoperative follow-up period, careful attention should be given to any recurrence, which in cases of Crohn’s disease is seen very early on rectoscopy.
Impact of vCJD on blood supply.
2007
Variant Creutzfeldt-Jakob disease (vCJD) is an at present inevitably lethal neurodegenerative disease which can only be diagnosed definitely post mortem. The majority of the approximately 200 victims to date have resided in the UK where most contaminated beef materials entered the food chain. Three cases in the UK demonstrated that vCJD can be transmitted by blood transfusion. Since BSE and vCJD have spread to several countries outside the UK, it appears advisable that specific risk assessments be carried out in different countries and geographic areas. This review explains the approach adopted by Germany in assessing the risk and considering precautionary measures. A fundamental premise is…
