The Effectiveness of Physical Exercise on Bone Density in Osteoporotic Patients
2018
Physical exercise is considered an effective means to stimulate bone osteogenesis in osteoporotic patients. The authors reviewed the current literature to define the most appropriate features of exercise for increasing bone density in osteoporotic patients. Two types emerged: (1) weight-bearing aerobic exercises, i.e., walking, stair climbing, jogging, and Tai Chi. Walking alone did not appear to improve bone mass; however it is able to limit its progressive loss. In fact, in order for the weight-bearing exercises to be effective, they must reach the mechanical intensity useful to determine an important ground reaction force. (2) Strength and resistance exercises: these are carried out with…
The release of choline from phospholipids mediated by beta-adrenoceptor activation in isolated hearts.
1986
The resting efflux of choline into the perfusate (Tyrode's solution) of isolated hearts was equal to the rate, at which choline was liberated from phospholipid degradation (Lindmar et al. 1986). Infusion of isoprenaline (2 X 10(-7) mol/l), forskolin (1-3 X 10(-6) mol/l) or 3-isobutyl-1-methylxanthine (IBMX; 3 X 10(-4) mol/l) for 40 min markedly enhanced the efflux of choline. The increase was linear during the experimental period and, in the case of isoprenaline, was blocked by 3 X 10(-7) mol/l atenolol. In the guinea-pig heart, IBMX at a threshold concentration of 10(-4) mol/l shifted the concentration-response curve for the effect of forskolin on the efflux of choline to the left by one l…
Rhein stimulates active chloride secretion in the short-circuited rat colonic mucosa.
1988
In a short-circuited mucosa-submucosa preparation of the rat descending colon with preserved Meissner's plexus mounted as an everted sac rhein transiently increased the potential difference and short-circuit current (Isc) when administered serosally and mucosally, but serosal application was more effective. Maximal effects were obtained at rhein concentrations of 1.6 X 10(-4) and 3 X 10(-4) mol/l. Net chloride absorption was decreased. Indomethacin (5 X 10(-6) mol/l) did not inhibit the increase of Isc, but omission of calcium from the serosal side as well as tetrodoxin (2 X 10(-7) mol/l) decreased it by 50 and 60%. Mechanical removal of Meissner's plexus partly blocked the effect of rhein,…
Online audio-visual information on oral cancer for Spanish-speaking laypersons. A cross-sectional study
2021
Background Lack of knowledge and awareness of oral cancer seem to be the main causes of diagnostic delay. Online resources are often used by patients to obtain health/medical information. However, there are no reports on the quality and usefulness of oral cancer audio-visual resources in Spanish. The aims of this investigation were to disclose the type of information about oral cancer available, and whether it may be useful to shorten the patients’ oral cancer appraisal time-interval. Material and Methods Cross-sectional study undertaken at three video-sharing sites on October, 13th 2019. Keywords: “Cáncer oral”; “cáncer de boca”. The first 100 results in each viewing list were retrieved by…
Superficial esophageal cancer: endoscopic resection or radical surgery?
2010
Barrett's esophagus: endoscopic resection
2003
In experienced hands, ER is a safe method of resecting dysplastic lesions and early carcinomas of the GI tract, and it has decisive advantages compared with other local endoscopic treatment procedures (such as thermal destruction and PDT). The opportunity for histological processing of the resected specimen provides information regarding the depth of invasion of the individual layers of the GI tract wall. Additionally, it has advantages regarding excision with healthy margins. This means that even when there is infiltration of the submucosa that has not been detected before treatment--in which case local endoscopic therapy is no longer appropriate--a patient with early Barrett's cancer stil…
Eustachian tube dysfunction in OSMF- often present seldom discovered
2014
Objectives: To evaluate the effect of OSMF on the eustachian tube function and to correlate it with various grades of the disease. Study Design: Twenty OSMF patients (40 ears) and 20 healthy controls (40 ears) were evaluated for eustachian tube function by eustachian tube function test, tympanometry and audiometry. Results: The audiometric and tympanometric analysis showed no significant differences in hearing abilities of OSMF patients and controls and between various grades of OSMF, indicating no hearing impairment. However, eustachian tube function test revealed a statistically significant difference in eustachian tube function in OSMF patients and controls. Further, there was a signific…
Plunging Ranula in a 78- year- old Male ? a rare case report
2018
The term Ranula is a Latin word meaning frog. It refers to a bluish translucent cystic lesion in the floor of the mouth resembling the underbelly of a frog. Ranulas can be true cysts occurring due to ductal obstruction of the sublingual gland or a minor salivary gland or a pseudocyst as a result of ductal injury leading to extravasation and accumulation of saliva in the surrounding tissues. Clinically ranulas present as intraoral or plunging ranulas. The prevalence of ranula is 0.2% per 1000 patients Ranulas account for 6% of all salivary gland cysts. Ranulas are more common in children and young adults. However the plunging type occurs most commonly in the later third decade. The diagnosis…
Endoscopic Resection of Early Esophageal and Gastric Neoplasias
2009
The advent of endoscopic resection (ER) techniques has enabled gastroenterologists to remove premalignant or neoplastic lesions throughout the gastrointestinal tract. This review discusses the indications and the several techniques of ER in early carcinomas of the esophagus and stomach. Before ER is performed an accurate evaluation of patients and careful staging of lesions is mandatory. After ER of the neoplasia histological assessment of the entire specimen with detailed histological analysis of layer infiltration is crucial. First long-term follow-up studies of large numbers of patients confirm the excellent effectiveness of ER for well-differentiated mucosal lesions without lymphangitic…
Comparisons of Submental and Groin Vascularized Lymph Node Flaps Transfer for Breast Cancer-Related Lymphedema
2018
Background:. The vascularized groin and submental lymph node (VGLN and VSLN) flaps are valuable options in the treatment of lymphedema. This study was to compare outcomes between VGLN and VSLN transfers for breast cancer–related lymphedema. Methods:. Between January 2008 and December 2016, VGLN and VSLN transfers for upper limb lymphedema were compared including flap characteristics, flap elevation time, complications, and limb circumference changes. Results:. All flaps survived. Similar vein (2.6 versus 3.2 mm; P = 0.3) and artery diameter (2.1 versus 2.8 mm; P = 0.3) and number of lymph nodes (3 versus 4; P = 0.4) were found between VGLN and VSLN groups, respectively. Circumferential redu…
