A Pilot Study Comparing the Use of Below-Knee and Above-Knee Graduated Stockings in Patients with Superficial Venous Incompetence

Objective: Investigation of the effects of high- and low-ankle-pressure, above- and below-knee compression stockings on the haemodynamics of normal and superficially incompetent venous systems. Design: Prospective duplex study of a normal group and a venous incompetence group randomised to high- or low-pressure stockings. Setting: Vascular services of a University Hospital. Subjects: Six subjects with normal venous haemodynamics (12 limbs) and 12 patients with superficial venous incompetence (20 limbs). Methods: Subjects wore below-knee and then above-knee stockings for 1 week each. Duplex scans were performed at the outset and end of the study and on fitting and after wearing each stocking type. Main outcome measures: Duplex-derived femoral and popliteal venous velocities were measured and indexed against the initial velocity. Results: Below-knee stockings produced only minor changes. Above-knee stockings produced increased velocities in normal subjects. Similar changes were only seen with higher-pressure stockings in patients with incompetence. Conclusion: Above-knee, high-ankle-pressure stockings produce increased deep venous flow velocities.

Objectives: To evaluate venous function during pregnancy and to compare two levels of graduated compression. Design: Prospective, randomized study. Setting: Vascular Surgery and Vascular Laboratory, University Hospital. Patients: Fifty pregnant women using graduated compression with pantyhose stockings exerting either 25 or 13 mmHg ankle pressure. Eight pregnant women acting as controls. Interventions: Foot volumetry to determine venous function (venous emptying during exercise and reflux) close to week 20, week 33 and post-partum. Results: The expelled volume increased significantly when graduated compression stockings were used. Refilling flow did not change significantly. Few patients with reflux were found. Conclusion: Graduated compression stockings of pantyhose type are effective in increasing venous emptying during pregnancy. Stockings exerting an ankle pressure of 13 mmHg at the ankle level were as effective as those exerting 25 mmHg.

Objective: To validate a placebo compression stocking. Design: Subjects were asked to identify as the same or different, placebo (P) and medical compression stockings (MCS) presented in a controlled randomised masked manner. Setting: A university hospital in Paris, France, and Innothera Laboratory. Patients, participants: One hundred and twenty-seven volunteers. Main outcome measures: Recognition of P versus MCS. Results: The false response rates in the visual test were 46.6% for physicians and 47.6% for non-physicians; in the touch test, 19.7% and 34.5% respectively, and in the wearing test, performed by non-physicians, 25.4%. Conclusions: P was valid in the visual part of the study but not in its touching or wearing parts. However, the large number of false responses in the non-physician group indicates that the use of a placebo stocking would be a methodological improvement compared with the usual open studies.

Abstract Objective The aim of the study is to observe the effect of post-stroke depression on functional outcomes during inpatient rehabilitation. Patients and Methods The design involved is prospective observational study. The location involved is Neurological Rehabilitation unit in a tertiary care university hospital. The study period ranges from October 2019 to April 2020. The participants involved are the patients with first ever stroke, male and female with age ≥18 years and duration less than 1 year. All participants were assessed at admission and after 14 sessions of inpatient rehabilitation by depression subscale of Hospital Anxiety and Depression Scale (HADS-D) and Hamilton Depression Rating Scale (HDRS). The stroke outcomes measures used were: Barthel Index (BI), Scandinavian Stroke Scale (SSS), and Modified Rankin Scale (MRS). Results There are a total of 30 participants (18 males) with median stroke duration of 90 days. The median age of the patients was 58 years. Sixteen patients had ischemic and 14 had hemorrhagic stroke. Out of these, 57% (n = 17) had symptoms of depression (HADS-D >7). Participants in both groups (with and without depression) showed improvement in all the functional outcome measures (BI, SSS, MRS) at the time of discharge as compared with admission scores. The changes in the outcome measures were statistically significant within groups (p < 0.05) but not significant between the groups (p > 0.05). Conclusion The post-stroke depression is common among stroke survivors of less than 1 year duration. There was no significant difference in the functional outcomes between stroke patients with depression and those without depression with inpatient rehabilitation program.

AbstractThe most common cause of chronic mesenteric ischaemia is atherosclerosis which results in limitation of blood flow to the gastrointestinal tract. This pilot study aimed to evaluate 4D flow MRI as a potential tool for the analysis of blood flow changes post-prandial within the mesenteric vessels. The mesenteric vessels of twelve people were scanned; patients and healthy volunteers. A baseline MRI scan was performed after 6 h of fasting followed by a post-meal scan. Two 4D flow datasets were acquired, over the superior mesenteric artery (SMA) and the main portal venous vessels. Standard 2D time-resolved PC-MRI slices were also obtained across the aorta above the coeliac trunk, superior mesenteric vein, splenic vein and portal vein (PV). In the volunteer cohort there was a marked increase in blood flow post-meal within the PV (p = 0.028), not seen in the patient cohort (p = 0.116). Similarly, there were significant flow changes within the SMA of volunteers (p = 0.028) but not for the patient group (p = 0.116). Our pilot data has shown that there is a significant haemodynamic response to meal challenge in the PV and SMA in normal subjects compared to clinically apparent CMI patients. Therefore, the interrogation of mesenteric venous vessels exclusively is a feasible method to measure post-prandial flow changes in CMI patients.

Objective To evaluate the possible association between the size of the premaxilla in infants and craniofacial morphology in children with complete bilateral cleft lip and palate (CBCLP) and identify the characteristics of craniofacial morphology in children with CBCLP with median facial dysplasia (MFD). Design Retrospective study. Setting A university hospital craniofacial center. Subjects Thirty-four patients with nonsyndromic CBCLP, 24 boys and 10 girls, had large premaxilla (LP group). Thirty-six patients with nonsyndromic CBCLP, 16 boys and 20 girls, had small premaxilla (SP group). Thirteen CBCLP patients with MFD, five boys and eight girls (MFD group). Main Outcome Measures Infant maxillary dental cast at the age of 1 year was used to measure the size of the premaxilla. Cephalometric analysis was used to determine craniofacial morphology in children at the age of 5 years. Results The size of the premaxilla in infants with CBCLP varied greatly. The LP group tended to have a longer maxilla and a more protruded maxilla, producing a better interjaw relation. The opposite phenomena were observed in the MFD group; the SP group yielded results between those of the LP and the MFD groups. Conclusion The size of the premaxilla in infants with CBCLP can be used to predetermine subsequent craniofacial morphology at the age of 5 years. Children with nonsyndromic CBCLP had craniofacial characteristics that differed significantly from those of children with CBCLP with median facial dysplasia.

Background: In this study, we promote a global approach to occupational risk perception in order to improve occupational health and safety training programs. The study investigates the occupational risk perception of operating room healthcare workers using an Analytic Hierarchy Process approach. Methods: A pilot study was carried out through a cross-sectional survey in a university hospital in Southern Italy. An ad hoc questionnaire was administered to enrolled medical post-graduate students working in the operating room. Results: Fifty medical specialists from seven fields (anaesthetists, digestive system surgeons, general surgeons, maxillofacial surgeons, thoracic surgeons, urologists, and gynaecologists) were questioned about perceived occupational risk by themselves. Biological, ionizing radiation, and chemical risks were the most commonly perceived in order of priority (w = 0.300, 0.219, 0.210). Concerning the biological risk, gynaecologists unexpected perceived this risk as less critical (w = 0.2820) than anaesthesiologists (w = 0.3354), which have the lowest perception of the risk of ionizing radiation (w = 0.1657). Conclusions: Prioritization methods could improve risk perception in healthcare settings and help detect training needs and perform sustainable training programs.
