ABSTRACT
Objective To observe changes in bone mass and symptom duration in patients with lumbar disc herniation(LDH) and explore the relationship between osteoporosis and clinical features of LDH. Methods 83 LDH patients undergoing surgery were enrolled in the study from November 2008 to September 2009. Before surgery, dual-energy X-ray absorptiometry was used to detect bone mineral density of lumbar spine and hip, and calculate T score. The patients were divided into three groups according to the T score: group A (normal bone mass group, n=27), group B (osteopenia group, n=31) and group C (osteoporosis group, n=25). The differences in the duration of symptoms and pathological types were compared between the groups. The relationship between BMI and lumbar spine T-score was explored. Results There were no significant differences in the pathological types among the three groups. The symptom duration in group C was significantly shorter than in group A (P < 0.05). There was no correlation between BMI and lumbar spine T-score (r=0.20, P=0.070). There was positive correlation between BMI and Hip T-score (r=0.263, P=0.016). Conclusion Osteoporosis may affect the symptom duration of LDH patients. We should attach great importance to patients with osteoporosis and LDH.
ABSTRACT
Background: Periodontitis and osteoporosis are two diseases found worldwide having the main characteristic of increasing intensity with age. Periodontitis is associated with resorption of the alveolar bone. Osteoporosis is characterized by bone loss leading to structural bone transformation. The association between periodontitis and osteoporosis is continually being examined. The aim of this study is to examine the condition of periodontal tissues in patients suffering from osteoporosis and establish a possible link. Materials and Methods: Cross‑sectional study with 200 samples having test (n = 100) and control group (n = 100) were checked for periodontal condition. A total of 100 patients diagnosed as having osteoporosis based on bone mineral density at distal end of radius were regarded as test group and 100 subjects included in control group were healthy. Periodontal parameters measured were plaque index (PI), gingival index (GI), probing depth (PD), and clinical attachment loss (CAL). Statistical test performed were Student’s paired t‑test and unpaired t‑test and Pearson’s correlation coefficient. Results: Probing depth and CAL were significantly negatively co‑related with T‑score in test group when compared with control group. This meant an inverse relationship in between the T‑score and the clinical parameters, PD and CAL. Furthermore, some difference was noted in test group in PI, GI and PD, CAL and T‑score when compared with the controls. Conclusion: Thus, we conclude that there is a definite relationship between osteoporosis and periodontitis based on PD and CAL.
ABSTRACT
PURPOSE: Although retractile testes are frequently found in the pediatric population, there are controversies in the management of retractile testes. We investigated the necessity of treatment for retractile testes by analyzing their histologic findings. MATERIALS AND METHODS: Sixty-one testicular biopsies were performed during orchiopexy from 36 boys(range: 1.3-12.9 years, mean: 5.4 years) with retractile testes(11 unilateral, 50 bilateral) and 115 testicular biopsies from 83 cryptorchid patients(range: 0.6-15.0 years, mean: 3.7 years, 51 unilateral, 64 bilateral). Parameters for both Sertoli cell and germ cell were determined in each group. RESULTS: The average tubular degeneration phase(TDP) V-VII were 0.23+/-0.18 for retractile testes and 0.22+/-0.17 for cryptorchid testes and were not statistically different. Both the average sertoli cell index(SCI) and mean spermatogonia per tubules(S/T) value were statistically different between retractile and cryptrochid testes with values of 26.81+/-6.75, 23.04+/-5.85(p<0.01) and 2.96+/-1.33, 0.61+/-0.87(p<0.01), respectively. CONCLUSIONS: Although S/T value of retractile testes was higher than that of cryptorchid testes, Sertoli cell degenerative patterns were similar. These findings might indicate that retractile testis needs treatment like cryptorchid testis does. However, further investigation is warranted to elucidate whether these changes are normal variations since changes are observed in both Sertoli & germ cells in normal boys as they are aging.
