Ultrasonographic Evaluation of the Distal Femoral Cartilage Thickness in Parkinson's Patients.

OBJECTIVES: Both Parkinson's disease (PD) and osteoarthritis (OA) are characterized by chronic inflammation and tissue degeneration. The aim of this study is to investigate the relationship between PD and distal femoral cartilage thickness (DFCT). Our study is the first in the literature to measure DFCT in PD. METHODS: 68 patients with PD and 30 healthy individuals participated. The patient group was divided into three subgroups, according to the Hoehn Yahr stages (HYS): mild, moderate and severe. Patient subgroups and the control group were compared with each other in terms of neutrophil-lymphocyte ratio (NLR), C-reactive protein (CRP), and DFCT. RESULTS: The NLR and CRP levels of the PD patients were higher than the values of the healthy people. The DFCT values of the mild PD subgroup were significantly higher than those of the control group, except for one value. The DFCT values of the moderate PD subgroup and the healthy group were similar. The DFCT values of the severe PD subgroup were lower than the values of the healthy group. CONCLUSIONS: Our study showed the presence of ultrasonographic evidence consistent with early signs of cartilage destruction in early-stage PD disease. As the PD stage progressed, the cartilage thickness decreased accordingly.

The relationship between cartilage thickness and muscle thickness or leg length discrepancy in poliomyelitis sequelae.

OBJECTIVES: To evaluate the relationship between cartilage loss and differences in muscle thickness and/or leg length in poliomyelitis sequelae (PMS). Our study is the first to evaluate the relationship between cartilage loss and both muscle atrophy and leg length discrepancy in the same population. METHODS: 37 patients with PMS and 38 healthy controls were included. Talar and distal femoral cartilage thicknesses and gastrocnemius medialis and quadriceps femoris muscle thicknesses were measured via ultrasound. Leg length differences and manual muscle strength were also evaluated. RESULTS: The mean muscle thicknesses and cartilage thicknesses were thinner in the more affected legs than in the less affected legs in the patient group. All of the ultrasonographic measurements were thinner in the less affected legs of the patient group than in the right legs of the control group, except for the knee cartilage thicknesses. While there was a correlation between the cartilage thickness difference and the muscle thickness difference between the less and more affected legs in the patient group, there was no correlation between the cartilage thickness difference and leg length differences. CONCLUSIONS: Patients with PMS are predisposed to osteoarthritis. Talar and knee cartilage thicknesses may be more associated with the muscle thickness than the leg length discrepancy in PMS.

Patients With Neuropathic Pain Have Poor Sleep Quality.

ABSTRACT: Although sleep disorders have been studied many times in neuropathic pain (NP), the effect of pain level, depression, and quality of life (QOL) on sleep quality in NP has been rarely investigated. In the present study, we aimed to investigate associations between possible quality of sleep (QOS) impairment and pain level, depression, and QOL. Average daily pain intensity, QOL, QOS, and depression status of the patients were evaluated using a 100-mm visual analog scale (VAS), the RAND 36-Item Health Survey 1.0, the Pittsburgh Sleep Quality Index, and Beck Depression Inventory (BDI), respectively. In 83.1% of patients QOS was found to be poor. We found that there was a significant difference between good and poor QOS in BDI, VAS, and RAND 36-Item Health Survey 1.0 scale's parameters, and patients with NP have poor sleep quality. Depression status is the main predictor for QOS, so pain level and QOL affect the QOS in NP. Physicians who aim healthy QOS must evaluate all characteristics of pain, depression status, and QOL in patients with NP.

Investigation of the Association between Headache Type, Frequency, and Clinical and Radiological Findings in Patients with Multiple Sclerosis.

AIM: In this study, we aimed to investigate the prevalence of primary headaches in patients with multiple sclerosis (MS), to determine the type of headache according to the criteria of International Headache Society and to investigate the relationship between primary headache type and MS subtype, and the relationship between the localization of plaques in the brain magnetic resonance imaging (MRI) with MS clinic. METHODS: In this study, we include the patients diagnosed with MS according to the Mc Donald criteria and functional loss determined with Expanded Disability Status Scale (EDSS). We include the patients who were questioned about headache characteristics in detail and the patients who have MRI previously. MRI evaluations of plaque localization of the patients were classified retrospectively. FINDINGS: Headache in 54.4% of 320 patients participated in the study are available (23.8% tension-type headache (TTH), 30.6% migraine). When we look at the first three initial symptoms of MS patients, the patients who have polysymptomatic symptoms at the beginning are 25.3%, those with motor symptoms are 23.1%, and patients with optical symptoms are 19.7%. The mean EDSS was 2.6 ± 1.9. When we look the lesion localization, at most pericallosal lesions are present. Mean disease duration was 9.9 years in patients with TTH and 4.5 years in patients with migraine. The difference was statistically significant (P < 0.05). The mean EDSS score was 4.7 in patients with TTH and 1.8 in patients with migraine, and the difference was statistically significant (P < 0.001). The average number of lesions in the brain was 22.07 in patients with TTH and 15.79 in patients with migraine. The difference was statistically significant (P < 0.001). RESULTS: In this study, the frequency of headache in MS patients was found to be greater than the general population and we found a higher incidence of migraine-type headache in these patients. We observed that the tension type of headache is more frequent in MS patients with higher ages, longer disease duration, more plaque numbers, and high EDSS scores.

Does transcutaneous nerve stimulation have effect on sympathetic skin response?

OBJECTIVE: This study examined the effects of transcutaneous electrical nerve stimulation (TENS) on the sympathetic nerve system by sympathetic skin response test. METHODS: Fifty-five healthy volunteers received either: (i) 30minutes TENS (25 participants) (ii) 30minutes sham TENS (30 participants) and SSR test was performed pre- and post-TENS. The mean values of latency and peak-to-peak amplitude of five consecutive SSRs were calculated. RESULTS: A significant amplitude difference was found between TENS and sham TENS group both in right and left hand (p=0.04, p=0.01, respectively). However there was no significant latancy difference between two groups (p>0.05 ). CONCLUSION: TENS has an inhibitory effect on elicited SNS responses when compared with sham TENS control group.

Two cases of primary stabbing headache.

Primary stabbing headache is an excruciating and relatively rare type of headache that typically lasts for only a few seconds. Pain is predominantly felt in the distribution of the first division of the trigeminal nerve and can be experienced as single stabs or as a series of stabs, either per day or every few days. Primary stabbing headache has been well-defined for decades and must be kept in mind during diagnosis. Exclusion of other possible causes is necessary in order to establish diagnosis. Indomethacin has classically been considered the first treatment option, but therapeutic failure occurs in up to 35% of cases. Recent studies have suggested that cyclooxygenase-2 inhibitors, gabapentin, nifedipine, paracetamol, and melatonin are also effective treatments.
