Neonatal Kidney Dimensions and Medullary Pyramid Thicknesses According to the Weight, Length and Body Mass Index of Newborns

Aim:The primary purpose of the present study was to investigate the relationship between neonatal kidney dimensions and medullary pyramid thicknesses (MPTs) according to the weight, length and body mass index (BMI) of newborns.Materials and Methods:A total of 237 [128 (54%) boys and 109 (46%) girls] consecutive term newborns in the first month of life were evaluated. Infants with an underlying renal disease, urinary symptoms, chromosomal abnormalities or low birth weight were excluded from the study. Greyscale ultrasound of neonatal kidneys was performed in standard transverse and longitudinal planes. Renal dimensions, parenchymal thickness and MPT were also evaluated and compared with neonatal age, height, weight, BMI and abdominal circumference (AC) and head circumferences (HC). Regression analyses were performed and graphs were plotted to determine the independent factors for renal parameters.Results:Statistically significant associations were noted in the renal dimensional measurements among neonatal weight (NW), neonatal length, BMI, HC and AC in the infants (p<0.0001). However, no statistically significant difference was observed between right kidney MPT and NW, HC, AC and BMI. In contrast, a statistically significant association was detected between left kidney MPT and NW, HC, AC and BMI.Conclusion:Neonatal kidney length, neonatal kidney width and renal parenchymal thickness measurements could be a useful method as an indicator of neonatal growth

The effects of vitamin D deficiency on mandibular bone structure: a retrospective radiological study

Objective The aim of the study was to evaluate the effects of vitamin D deficiency on the mandibular bone structure by fractal analysis and panoramic morphometric indices. Methods Ninety participants were divided into three groups as 30 individuals with severe vitamin D deficiency, 30 individuals with vitamin D deficiency, and 30 individuals with vitamin D sufficiency. Fractal dimension analysis (FD), panoramic mandibular index (PMI), mandibular cortical index (MCI), and mandibular cortical thickness measurement (CTM) were evaluated on panoramic radiographs. Results FD values of the patients with vitamin D deficiency were found to be statistically lower than the patients with vitamin D sufficiency (p 0.05). PMI was significantly lower in patients with severe vitamin D deficiency (p < 0.001). There was a significant difference in MCI values between the groups (p < 0.05). Conclusion Vitamin D deficiency causes a decrease in bone mineral density in the mandible, and an increase in alveolar porosity. FD analysis and radiomorphometric indices in panoramic radiographs can be used to assess osteoporotic changes in patients with vitamin D deficiency

The effects of IL-10 gene polymorphism on serum, and gingival crevicular fluid levels of IL-6 and IL-10 in chronic periodontitis

Objective Anti-inflammatory cytokines play a crucial role in periodontitis by inhibiting synthesis of pro-inflammatory cytokines. The purpose of this study was to evaluate the effect of interleukin-10 (-597) gene polymorphism and genotype distributions on chronic periodontitis (CP) development and IL-6 and IL-10 levels in gingival crevicular fluid (GCF) and serum before and after non-surgical periodontal treatment. Material and Methods The study population consisted of 55 severe generalized CP patients as CP group and 50 healthy individuals as control group. Plaque index, gingival index, probing depth and clinical attachment level were recorded and GCF and blood samples were taken at both the baseline and the sixth week after non-surgical periodontal treatment. PCR-RFLP procedure was used for gene analyses and cytokine levels were measured via ELISA. Results IL-10 genotype distribution was significantly different between CP and control groups (p=0.000, OR:7, 95%CI, 2.83-60.25). Clinical measurements significantly improved in the CP group after periodontal treatment (p;0.05). Sixth week GCF IL-10 levels were significantly lower in patients carrying IL-10 AC+CC genotype compared to the patients carrying IL-10 AA genotype (p;0.05). Conclusion IL-10 AA genotype carriers had lower IL-6 and IL-6/10 levels in serum; however, GCF IL-6/10 levels were similar in both genotypes. Within the limitations of our study, a possible association between IL-10(-597) gene polymorphism and CP might be considered

A case of acromegaly in the presence of coincidental liver cirrhosis

Context: Acromegaly is a rare and serious syndrome and commonly associated with pituitary neoplasm. Classic cause of acromegaly in adults is the tumors of the somatotrophs that secrete growth hormone. Cirrhosis is the end stage of chronic liver disease and commonly a cause of death. It is characterized by diffuse hepatic fibrosis resulting in altered construction of the lobular parenchyma with widespread connective tissue scptae, circumscribed regenerative nodules of hepatocytcs and anastomoses between vascular channels linking portal and central vessels. Objective: To report the simultaneous cases of acromegaly and cirrhosis. Case report: A 62-year old, male patient came to the hospital complaining of severe abdominal swelling. Laboratory and imaging findings were compatible with the presence of hepatitis B virus related cirrhosis together with acromegaly. In this case, he had high GH level but lower IGF-1 level because of hepatic failure which can impair IGF-1 production by the liver. Definitive diagnosis was made by pituitary MR and a 1 cm in diameter tumor was detected. Conclusion: This paper showed that cirrhosis can result in a low IGF-I level in patients with acromegaly. There is no previous report available of the in the presence of coincidental combination of acromegaly and cirrhosis in a patient

Measuring tactile sensitivity and mixed-reality-assisted exercise for carpal tunnel syndrome by ultrasound mid-air haptics

IntroductionCarpal tunnel syndrome (CTS) is the most common nerve entrapment neuropathy, which causes numbness and pain in the thumb, the index and middle fingers and the radial side of the ring finger. Regular hand exercises may improve the symptoms and prevent carpal tunnel surgery. This study applied a novel ultrasonic stimulation method to test tactile sensitivity in CTS and also a mixed-reality-assisted (MR-assisted) exercise program which measured hand movements and provided haptic feedback for rehabilitation.MethodsTwenty patients with mild unilateral CTS took part in the experiments. A mid-air haptics device (Ultrahaptics STRATOS Explore) was used to apply amplitude-modulated ultrasound waves (carrier frequency: 40 kHz) onto the skin to create tactile stimulation mechanically. Participants performed a two-alternative forced-choice task for measuring tactile thresholds at 250-Hz modulation frequency. They were tested at the index fingers and the thenar eminences of both hands. Additionally, 15 CTS patients used an MR-assisted program to do hand exercises with haptic feedback. Exercise performance was assessed by calculating errors between target and actual hand configurations. System Usability Scale (SUS) was adopted to verify the practical usability of the program.ResultsThresholds at the thenar eminences of the affected and healthy hands were not significantly different. While the thresholds at the healthy index fingers could be measured, those of the affected fingers were all higher than the stimulation level produced by the maximum output from the ultrasound device. In the exercise program, a significant positive correlation (ρ = 0.89, p &lt; 0.001) was found between the performance scores and the SUS scores, which were above the criterion value established in the literature.DiscussionThe results show that thenar tactile sensitivity is not affected in mild CTS as expected from the palmar cutaneous branch of the median nerve (PCBm), but index finger threshold is likely to be higher. Overall, this study suggests that mid-air haptics, with certain improvements, may be used as a preliminary test in the clinical setting. Moreover, the device is promising to develop gamified rehabilitation programs and for the treatment follow-up of CTS
