Abstract

A prospective study was conducted to determine the diagnostic value of sonography in suspected acute appendicitis. From September 1987 until May 1988, the end of the study, 152 patients suspected of having "acute appendicitis" were admitted to hospital. In contrast to other recently published studies conducted by a few highly qualified examiners, we dimed at determining whether this method is useful as a 24-hour-screening performed ba y number of more or less qualified examiners. In the beginning, the patients were examined with a 3.5 MHz scanner, later on exclusively with 5 MHz linear and sector scanners. 150 cases could be evaluated, 96 of which underwent surgery. We found 35 sonographically correct results, 89 correctly negative, 4 false positive and 13 false negative diagnoses. This means a sensitivity of 73% and a specificity of 96% for the sonographical diagnostic method. In 20 cases (13%) sonography led to other diagnoses. A large majority of these findings can be detected by less experienced examiners. The goal of a 24-hour-screening could not be reached because there a competent examiner was not always available at night. It became clear that clinically obvious cases do not require sonographic conformation. The value of sonography lies with doubtful cases of appendicitis: if the ultrasound examination is negative, appendectomy can be postponed; if sonography leads to other differential diagnoses, appropriate therapy can be started immediately.

Abstract

Purpose: To evaluate and follow-up of functional and morphological changes of the optic nerve and ocular structures prospectively in patients with early-stage Parkinson's disease., Materials and Methods: Nineteen patients with a diagnosis of early-stage Parkinson's disease and 19 age-matched healthy controls were included in the study. All participants were examined minimum three times at the intervals of at least 6 month following initial examination. Pattern visually evoked potentials (VEP), contrast sensitivity assessments at photopic conditions, color vision tests with Ishihara cards and full-field visual field tests were performed in addition to measurement of retinal nerve fiber layer (RNFL) thickness of four quadrants (top, bottom, nasal, temporal), central and mean macular thickness and macular volumes., Results: Best corrected visual acuity was observed significantly lower in study group within all three examinations. Contrast sensitivity values of the patient group were significantly lower in all spatial frequencies. P100 wave latency of VEP was significantly longer, and amplitude was lower in patient group; however, significant deterioration was not observed during the follow-up. Although average peripapillary RNFL thickness was not significant between groups, RNFL thickness in the upper quadrant was thinner in the patient group. While there was no difference in terms of mean macular thickness and total macular volume values between the groups initially, a significant decrease occurred in the patient group during the follow-up. During the initial and follow-up process, a significant deterioration in visual field was observed in the patient group., Conclusion: Structural and functional disorders shown as electro-physiologically and morphologically exist in different parts of visual pathways in early-stage Parkinson's disease.

Abstract

Objectives: To evaluate the magnetic resonance imaging (MRI)-derived parameters in differentiation of patients with progressive supranuclear palsy (PSP) from patients with Parkinson's disease (PD), multiple system atrophy (MSA), and control subjects was aimed., Methods: Thirty-three patients [mean age, 65.21 ± 4.75 years; PSP (n = 9), MSA (n = 8), PD (n = 6), and control subjects (n = 10)] who have undergone cranial MRI were included in this retrospective study. MRI-derived parameters including areas of midbrain and pons, midbrain area-to-pons area (M/P) ratio, widths of middle cerebellar peduncle (MCP) and superior cerebellar peduncle (SCP), MCP/SCP ratio, magnetic resonance parkinsonism index (MRPI), cerebral interpeduncular angle, and length of midbrain tegmentum were compared in patients with PSP, PD, MSA, and control subjects through the analysis of variance and Kruskal-Wallis tests with Bonferroni correction and Mann-Whitney U test., Results: The length of midbrain tegmentum, midbrain area, SCP, and M/P ratio were found to be lower, while cerebral interpeduncular angle and MRPI were higher in patients with PSP. Pons area, MCP width, and MCP/SCP ratio were found to be lower in patients with MSA. For PSP, cerebral interpeduncular angle has a sensitivity of 100% and specifity of 90%, and MRPI had a sensitivity of 88.9% and specifity of 100% for PSP., Discussion: Several MRI-derived parameters can be used in differentiation of patients with PSP from patients with PD, MSA and control subjects. The cerebral interpeduncular angle and MRPI, which demonstrated higher values in patients with PSP, were more significant for PSP than the other parameters.

Background: Patients with Parkinson's disease complain about restrictions in their daily life activities and impairment in their mobility and balance., Objective: The aim of this study was to compare the effects of vestibular rehabilitation on functioning, quality of life, balance, and postural stability in patients with Parkinson's disease., Methods: The patients with Parkinson's disease divided into a rehabilitation group (Group 1, n: 29) and a control group(Group 2, n: 11). All patients were evaluated before and after eight weeks of customized vestibular rehabilitation for motor score (Unified Parkinson's Disease Rating Scale); quality of life (Parkinson's Disease Questionnaire-39); balance (Activities-Specific Balance Confidence Scale [ABC], Timed Up and Go Test, Dynamic Gait Index [DGI], and Berg Balance Scale [BBS]); and postural stability (Modified Clinical Test for Sensory Interaction on Balance [mCTSIB]., Results: There were significant differences in the pre- and post-exercise ABC, BBS, and DGI scores in Group 1 (p <  0.05). A statistically significant impairment was observed in mCTSIB (firm and foam eyes closed [EC]) in the control group (p <  0.05). There were no significant intergroup differences in any of the parameters evaluated (p >  0.05)., Conclusion: In this study, vestibular rehabilitation was found to be effective for improving balance in patients with Parkinson's disease.

Abstract

The purpose of this study was to investigate the short-term effects of static stretching, with vibration given directly over Achilles tendon, on electro-myographic (EMG) responses and vertical jump (VJ) performances. Fifteen male, college athletes voluntarily participated in this study (n=15; age: 22±4 years old; body height: 181±10 cm; body mass: 74±11 kg). All stages were completed within 90 minutes for each participant. Tendon vibration bouts lasted 30 seconds at 50 Hz for each volunteer. EMG analysis for peripheral silent period, H-reflex, H-reflex threshold, T-reflex and H/M ratio were completed for each experimental phases. EMG data were obtained from the soleus muscle in response to electro stimulation on the popliteal post tibial nerve. As expected, the dynamic warm-up (DW) increased VJ performances (p=0.004). Increased VJ performances after the DW were not statistically substantiated by the EMG findings. In addition, EMG results did not indicate that either static stretching (SS) or tendon vibration combined with static stretching (TVSS) had any detrimental or facilitation effect on vertical jump performances. In conclusion, using TVSS does not seem to facilitate warm-up effects before explosive performance.

Abstract

Objectives: We aimed to evaluate long-term changes in left ventricular (LV) longitudinal systolic functions in patients with asymptomatic, severe aortic regurgitation (AR) by using novel 2D strain imaging., Methods and Results: Thirty severe AR patients with normal ejection fraction (EF) and 30 healthy controls were evaluated by both conventional echocardiography and velocity vector maging (VVI) based strain imaging at baseline and 24 months follow-up. To evaluate LV longitudinal systolic function, segmental peak systolic strain and strain rate (SRs) data were acquired from apical four-chamber, two-chamber and long-axis views. Longitudinal peak systolic strain and SRs of the LV were decreased in patients with severe AR compared to controls at baseline (P = 0.0001). The impairment was more significant in 24 months follow-up (P = 0.0001 for strain, P = 0.01 for SRs). Longitudinal peak systolic strain was significantly correlated with left ventricular end-diastolic (LVEDD; r =-0.42, P = 0.0001) and left ventricular end-systolic diameter (LVESD) (r =-0.41, P = 0.0001) There was also a strong negative correlation between LV SRs and LVEDD (r =-0.50, P = 0.0001), and LVESD (r =-0.39, P = 0.0001)., Conclusions: VVI-derived strain and SRs may be used as adjunctive, noninvasive parameters in the assessment of subclinical LV dysfunction and its progress during clinical follow-up, in patients with severe AR., (© 2011, Wiley Periodicals, Inc.)

Abstract

Objective: To determine the characteristics of spontaneous cavernosal activity (SCA) and to relate this to previous descriptions of spontaneous potentials from the cavernosum (single potential analysis of cavernosal activity, SPACE)., Subjects and Methods: The SCA was recorded in 31 normal men with no sexual problems; various manipulations were applied using concentric-needle (CN), bipolar needle (BN) and surface electrodes. The electrical activity was compared with the observed slow retractile movements of the flaccid penis and with other assessments of electrical activity from skin., Results: SCA appeared synchronously from both sides of the cavernosal bodies in all normal subjects when detected by CN electrodes. The synchronous recordings both by CN and BN electrodes, or both by CN and surface electrodes registered similar oscillatory potentials. Slow retractile movements of the penis occurred synchronously with these potentials in all subjects and both were absent during erection., Conclusion: SCA is apparently related to biomechanical slow movement artefacts of the flaccid penis: it may be a consequence of the summed contractions of smooth muscle groups in the cavernosum. Observing the small retractile slow movements of the flaccid penis and recording the SCA may be a useful indirect method to characterize cavernosal neural innervation and smooth muscle activity.

Abstract

Objective: To determine the neurophysiological and vascular factors in diabetic impotence, particularly the role of autonomic neuropathy on venous leakage and erectile impotence., Patients and Methods: Thirty-four diabetic men with impotence were investigated using various neurophysiological and radiological methods. The results were compared with those from patients with idiopathic penile venous leakage for autonomic neuropathy, especially for spontaneous cavernosal activity (SCA)., Results: Of the neurophysiological tests, the SCA was most frequently abnormal, with the loss of normal periodic oscillations. Penile venous leakage, either alone or with arterial insufficiency, was the most frequent vascular problem (67%) in patients with diabetic impotence, in whom the SCA was absent in most (83%). Conversely, the SCA was normal in all impotent patients with idiopathic venous leakage., Conclusion: Venous leakage in diabetic patients is probably produced by autonomic dysfunction of the penile vascular innervation or degeneration of penile smooth muscles, because the SCA was absent more often in these patients.

Abstract

Objective: To investigate the analgesic effort of local superficial heating by studying sympathetic skin responses., Design: Randomized trial., Setting: Electromyography laboratory in the department of physical therapy and rehabilitation of a university hospital., Subjects: Twenty healthy volunteers participated with informed consent., Interventions: Sympathetic skin response (SSR) amplitudes following electrical stimulation of the right peroneal nerve and skin temperatures in both hands were recorded simultaneously. All of the recordings were repeated at 5-minute intervals during local heat application over the right palm and within 15 minutes after heat application was stopped., Results: SSR amplitudes in both hands decreased significantly during local heating (p < .05) and did not return to their initial levels within 15 minutes of the recovery period; the reductions remained statistically significant (p < .05). Amplitude reductions were statistically more significant on the heated hand compared with those on the contralateral hand (p < .05)., Conclusion: Therapeutic local heat application reduces the sudomotor response to a painful stimulus. This analgesic effect may be due to suppression of cortical pain sensation resulting from increased levels of endorphins, and may also be a result of local inhibition of both afferent and efferent C fibres.

Abstract

Peripheral sympathetic activity was investigated in 25 Parkinson's disease (PD) patients and 27 healthy subjects by measuring the skin resistance level (SRL) and skin resistance response (SRR) at the palm of the hand during rest, auditory stimulation and patellar tendon tapping. Blood flow to the hand was also monitored. Normal responses were obtained from all the 27 healthy subjects with both stimuli. All but one of the 25 PD patients responded to sound, six patients failed to respond to patellar tendon tapping and one patient failed to respond to both stimuli. The SRRs (when detectable) of PD patients were always smaller in amplitude than those of normal subjects. It was also observed that while an electrodermal response was present, no vasomotor response could be elicited by either stimulus in some patients. The opposite was true in some other patients. When response latencies were evaluated, it was found that although the mean latency of SRRs evoked by tendon taping was shorter than the mean latency of responses to auditory stimuli in normal subjects, this was not the case in PD patients. SRR mean latency to patellar tendon tapping was significantly longer in PD patients compared with that in normal subjects. Mean latencies of responses to auditory stimuli were the same for both normal subjects and patients. The ratio of the SRR amplitude to SRL (i.e. relative change in SRL) during both types of stimulation was significantly smaller in PD patients than in normal subjects. All the above findings were also true when blood flow to the tissue was interrupted briefly. These findings support the conjecture that the abnormal peripheral sympathetic neural responses associated with PD may arise from a functional disorder in the basal ganglia that influence the efferent autonomic pathway, from impairment of the intermediolateral column of the spinal cord, and possibly from cognitive deficits.

Abstract

A prospective study was conducted to determine the diagnostic value of sonography in suspected acute appendicitis. From September 1987 until May 1988, the end of the study, 152 patients suspected of having "acute appendicitis" were admitted to hospital. In contrast to other recently published studies conducted by a few highly qualified examiners, we dimed at determining whether this method is useful as a 24-hour-screening performed ba y number of more or less qualified examiners. In the beginning, the patients were examined with a 3.5 MHz scanner, later on exclusively with 5 MHz linear and sector scanners. 150 cases could be evaluated, 96 of which underwent surgery. We found 35 sonographically correct results, 89 correctly negative, 4 false positive and 13 false negative diagnoses. This means a sensitivity of 73% and a specificity of 96% for the sonographical diagnostic method. In 20 cases (13%) sonography led to other diagnoses. A large majority of these findings can be detected by less experienced examiners. The goal of a 24-hour-screening could not be reached because there a competent examiner was not always available at night. It became clear that clinically obvious cases do not require sonographic conformation. The value of sonography lies with doubtful cases of appendicitis: if the ultrasound examination is negative, appendectomy can be postponed; if sonography leads to other differential diagnoses, appropriate therapy can be started immediately.
