Consequences of Sarcopenia in Older People: The Epidemiological Evidence
2021
Sarcopenia is a common condition in older people. Increasing literature is showing its importance for negative health outcomes, also beyond the perimeter of geriatric medicine. In this chapter, we will discuss the consequences of sarcopenia. Overall, epidemiological research suggests that sarcopenia is significantly associated with falls and fractures also suggesting a strong association between muscle and bone loss conditions, as in the case of osteosarcopenia. Moreover, sarcopenia is associated with disability, hospitalization (particularly in older people already hospitalized), and finally mortality. Increasing research is also showing that sarcopenia is associated with negative outcomes…
Potential of human serum albumin as chiral selector of basic drugs in affinity electrokinetic chromatography-partial filling technique
2006
The enantiomeric resolution of compounds using HSA by means of affinity EKC (AEKC)-partial filling technique is the result of a delicate balance between different experimental variables such as protein concentration, running pH (background electrophoretic buffer (BGE), protein, and compound solutions), and plug length. In this paper, the possibility of using HSA as chiral selector for enantioseparation of 28 basic drugs using this methodology is studied. The effect of the physicochemical parameters, the structural properties of compounds, and compound-HSA protein binding percentages over their chiral resolution with HSA is outlined. Based on the results obtained, a decision tree is proposed…
Evidence of a preprogrammed deactivation of the hamstring muscles for triggering rapid changes of posture in humans
1997
Normal subjects were asked to make rapid flexions of the legs from a stationary initial standing posture in a self-paced mode. Because this movement implicates a rapid change in posture, questions were asked about the type of central command which must include the rupture of the erect posture and the accomplishment of the goal directed movement. Movements of the different segments of the body were recorded and analyzed using the optoelectronic ELITE system. Electromyographic (EMG) activities of 8 muscles of the lower limb on one side were recorded, rectified and integrated. The time relationships of the different EMG signals (activation or deactivation) were analyzed with respect to selecte…
Choroidal osteoma with choroidal excavation and associated neovascular membrane: An OCT-angiography study.
2017
Abstract Clinical case A case is presented of a unilateral choroidal osteoma with choroidal excavation and associated neovascular membrane that was studied using OCT-angiography. The OCT and OCT-angiography revealed an area of choroidal excavation and an active neovascular membrane. Three doses of aflibercept were administered to the patient, which stabilized the neovascularisation. Discussion OCT-angiography was used to analyze the morphology of the superficial vascular network of the osteoma, as well as to monitor the evolution of the neovascular membrane.
Effects of 12-wk eccentric calf muscle training on muscle-tendon glucose uptake and SEMG in patients with chronic Achilles tendon pain
2014
High-load eccentric exercises have been a key component in the conservative management of chronic Achilles tendinopathy. This study investigated the effects of a 12-wk progressive, home-based eccentric rehabilitation program on ankle plantar flexors' glucose uptake (GU) and myoelectric activity and Achilles tendon GU. A longitudinal study design with control ( n = 10) and patient ( n = 10) groups was used. Surface electromyography (SEMG) from four ankle plantar flexors and GU from the same muscles and the Achilles tendon were measured during submaximal intermittent isometric plantar flexion task. The results indicated that the symptomatic leg was weaker ( P < 0.05) than the asymptomatic…
Discovery of an epidermoid of the skull concomitant with a homolateral subacute traumatic subdural hematoma
1979
The case of a man of 32 years with an epidermoid of the left side of the skull is reported. The tumor itself was asymptomatic and was discovered accidentally because of a subdural hematoma on the same side. After a closed head injury, this patient had symptoms of an intracranial space occupying lesion (hematoma) on the left after a symptom-free interval. The left carotid angiogram demonstrated the characteristic picture of a subdural hematoma in the left parieto-temporo-occipital region. At the same time, characteristic changes in the skull on the same side, which were more apparent after removal of the hematoma, suggested an epidermal tumour of the skull. This was verified at operation.
Foot and Lower Limb Clinical and Structural Changes in Overuse Injured Recreational Runners Using Floating Heel Shoes: Preliminary Results of a Rando…
2021
Foot-strike and the associated load rate are factors related to overuse injuries in runners. The purpose of this study was to analyse structural and functional changes in runners using floating heel running shoes, compared with runners using conventional footwear. A randomised control trial was conducted. Twenty runners with overuse injuries were followed over a 12-week gait retraining programme using floating heel running shoes or their conventional footwear. Pain was measured with pressure pain thresholds (PPTs), structural changes were measured with ultrasonography, and severity and impact of injury was scored on the Oslo Sports Trauma Research Centre Overuse Injury Questionnaire (OSTRC-…
Abnormal Somatosensory Evoked Potentials Indicate Compressive Cervical Myelopathy in Mucopolysaccharidoses
2000
Compressive myelopathy at the cranio-cervical junction is a complication of mucopolysaccharidoses (MPS). To detect cervical myelopathy we recorded median and posterior tibial nerve SEPs in 15 patients aged 2.4 - 33.4 years (median 8.8 years) with MPS I-S (n = 3), MPS IVA (n = 8) and MPS VI (n = 4). In addition to the cortical waveforms we recorded the subcortical median nerve SEPs N13b and P13 generated near the cranio-cervical junction and the lemniscal P30 after posterior tibial nerve stimulation. MRI studies in 13 subjects revealed spinal cord compression at the cranio-cervical junction in 10 patients; 5 patients had an increased signal intensity on the T2-weighted initial MRI indicating…
Tarsal coalitions as a cause of pain in the foot of children: Therapeutic options
2021
Background and objective: The tarsal coalition can be a cause of mid-hindfoot pain in older children. The objective is to analyze the types of coalition treated in our hospital from 2010 to 2019 as well as the treatment carried out. Material and method: Observational, descriptive and retrospective study of 18 patients with tarsal coalition, 8 women and 10 men, aged 11.9±2.6 years. Epidemiological data, clinical findings and imaging tests, and treatment performed were collected. Results: Twenty-five feet (38.8% bilateral) were reviewed. The main symptom was pain. Sixty-four percent were associated with flat-valgus foot. Fifty-two percent were located in the calcaneal-scaphoid joint, and 40% …
Papular-purpuric gloves-and-socks syndrome : presentation of a clinical case
2007
Papular-Purpuric Glove-and-Sock Syndrome is a rare, infectious disease, of viral etiology, characterized by the presence of pruritus, edema and symmetrical erythema, very well defined at the wrists and ankles with a gloves-and-socks distribution. Other areas can be affected, with a moderate erythema appearing in cheeks, elbows, knees, armpits, abdomen, groin, external genitalia, internal face of the thighs and the buttocks. Erosions, small ulcers, enanthema and blisters can be observed in the oral cavity and lips, and less frequently in other mucous membranes. Complications are rare, although they can be severe, 50% of the published cases are related with the Parvovirus B19. Due to its oral…
