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.

The effect of ferritin levels on distal femoral cartilage thickness in patients with beta thalassaemia major.

INTRODUCTION: To the best of our knowledge, the present study is the first in the literature to assess distal femoral cartilage thickness and its relationship with ferritin levels in adult patients with beta thalassaemia major (BTM). MATERIALS AND METHODS: 45 patients with BTM and 45 healthy controls were included in the study. Ferritin and haemoglobin levels of the patient and healthy groups were determined by blood analysis and distal femoral cartilage thicknesses were measured via ultrasound. Then, the patient group was divided into subgroups according to whether their ferritin levels were below or above 2500 µg/L. They were then compared among themselves and with the healthy control group using the available data. RESULTS: Distal femoral cartilage thickness values were statistically significantly lower in the BTM group compared to the healthy control group (p values < 0.001). Patients with a ferritin level below 2500 µg/L had statistically significantly higher right and left average distal femoral cartilage thickness values than the patients with a ferritin level above 2500 µg/L (p = 0.029 and p = 0.019, respectively). The right and left average distal femoral cartilage thickness values of the patient subgroup with low ferritin levels were statistically similar to the control group (p = 0.146 and p = 0.164, respectively). CONCLUSION: Our study showed that thalassaemia patients are more likely to develop osteoarthritis (OA) than the normal population and possible OA development can be prevented by keeping the ferritin levels of these patients in the optimum range.

Baseline characteristics associated with survival in patients with hepatocellular carcinoma.

Background and Aim: Hepatocellular carcinoma (HCC) is one of the most common and most lethal cancers worldwide. The objective of this study was to investigate the relationship between basal parameters and survival characteristics in patients with HCC. Materials and Methods: The records of 1447 HCC patients of a tertiary center during the period 2000-2017 were screened retrospectively. The demographic details; basal clinical, laboratory, and radiological characteristics; treatments; and survival time were recorded and prognostic scores were calculated. Results: A total of 788 patients with HCC (male/female: 623/165; mean age: 60.5±10.9 years) were included in the study. The median length of survival was 26.3 months (95% confidence interval [CI], 22.3-30.4 months). The 5-year survival rate was 28.1%. The number and diameter of the tumors; platelet count; platelet-to-lymphocyte ratio; level of aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyl transferase; portal and hepatic vein involvement; and an alpha-fetoprotein level of <9.6 ng/mL were found to be independently related to survival. Conclusion: The positive predictive value of the prognostic index derived from independent survival-related parameters for 5- and 10-year survival or overall survival was approximately 86%. Integration of this prognostic index to the criteria used in making treatment decisions for patients with HCC should be considered.

Hepatitis E virus IgG seroprevalence in liver transplant patients: A retrospective single-center experience.

Background and Aim: Hepatitis E virus (HEV) may cause chronic liver disease in solid organ transplant recipients. We determined HEV seroprevalence and associated factors in liver transplant recipients. Materials and Methods: Patients followed at the outpatient clinic of liver transplantation between January 2019 and January 2020 were screened retrospectively for HEV serology (HEV immunoglobulin M [IgM] and HEV immunoglobulin G [IgG]). Results: Of the 150 patients (male/female, 104/46; age, 55.4±13.2 years), anti-HEV IgG was positive in 31 (20.7%), and anti-HEV IgM was negative in all. The mean time after liver transplantation (72 [48%] deceased and 78 [52%] living donors) was 81±78.5 months. Drinking water consisted of carboy and tap water in 88 (58.7%) and 62 patients (41.3%), respectively. Of the patients, 120 (80%) and 30 (20%) lived in urban and rural areas, respectively. On comparison, the difference between positive and negative anti-HEV IgG groups in terms of age, place of birth, water supply, and donor type was statistically significant (p=0.007, p=0.000, p=0.034, and p=0.049, respectively). Conclusion: HEV seroprevalence was more frequent in liver transplant recipients compared with the normal population. Older age, water supply, and place of birth were risk factors for HEV seroprevalence.

Effects of radial extracorporeal shock wave therapy on clinical variables and isokinetic performance in patients with knee osteoarthritis: a prospective, randomized, single-blind and controlled trial.

OBJECTIVE: This study aims to compare the efficacy of r-ESWT treatment with sham-ESWT on pain, walking speed, physical function, and isokinetic muscle strength in knee osteoarthritis. METHODS: The study included 104 patients (mean age 61.0 ± 6.2 years; range 50 to 70 years) who were admitted to our outpatient clinic with newly diagnosed with knee osteoarthritis. Patients were randomly assigned to two groups. Both groups received transcutaneous electrical nerve stimulation for 30 minutes, hot pack for 40 minutes, and home-based exercise program of around the knee strengthening for 30 minutes in a day for three weeks (5 days in a week). Also, one group was treated with r-ESWT, while the other group was treated with sham-ESWT. For r-ESWT, patients received 2000 pulses of shockwave at 2.0 to 3.0 bar weekly for three weeks. All patients were evaluated with visual analog scale (VAS), active knee range of motion (ROM), 20-metre walk test, Western Ontario and McMaster Osteoarthritis Index (WOMAC), Lequesne's disability index, and isokinetic muscle performance before treatment, at the end of treatment, at one month and three months after treatment. RESULTS: When groups were compared, group 1 scores were significantly better than the group 2 in all outcome parameters except WOMAC-stiffness at the end of treatment, at one month and three month follow-up (all p < 0.05). The VAS-resting, VAS-movement, knee ROM, 20-m walk test, WOMAC, and Lequesne's disability scores and peak torque values of knee extension improved in both groups with the highest improvement in the r-ESWT group. A comparison of difference of the two group scores showed statistically significant superior improvement in group 1 in all parameters at both one month and three months. CONCLUSION: Our findings revealed that r-ESWT combined with conventional electrotherapy is an effective treatment for improving pain and physical function in knee osteoarthritis to control symptoms up to three months.

Decreased central corneal thickness in ankylosing spondylitis.

Central corneal thickness and dry eye tests were evaluated in a study population consisting of 68 ankylosing spondylitis patients diagnosed according to the modified New York criteria, and 61 age-matched controls without ankylosing spondylitis. A full ophthalmological evaluation was performed on each subject. All subjects were screened for age, gender, HLA-B27, tear break-up time test, Schirmer test, and duration of disease. Central corneal thickness was measured under topical anesthesia with an ultrasonic pachymeter. The mean central corneal thickness was 537.3 ± 30.6 µm, range 462-600 µm, in ankylosing spondylitis patients, whereas it was 551.7 ± 25.2 µm, range 510-620 µm, in controls (p = 0.005). The Schirmer test result was 7.3 ± 5.9 mm for the ankylosing spondylitis patients and 11.7 ± 5.8 mm for the control group (p = 0.002). Tear break-up time was 7.3 ± 3.2 s for the ankylosing spondylitis patients and 14.0 ± 4.5 s for the control group (p < 0.001). The possibility of a thinner cornea should be taken into consideration in ankylosing spondylitis. In addition, attention must be given to lower dry eye tests in surgical interventions such as photorefractive keratectomy and laser in situ keratomileusis in ankylosing spondylitis patients.
