Background. Benign prostatic hyperplasia (BPH) can raise prostate-specific antigen (PSA) levels two to three times higher than the normal level. An increased PSA level does not indicate Prostate Cancer (PCa), but the higher the PSA level, the higher the chance of having PCa. Detection and treatment have been profoundly affected by the advent of Free/Total PSA ratio testing. Objectives. The aim of the study was to estimate free, total PSA levels and its ratio for serum levels of calcium, acid phosphatase and alkaline phosphatase in patients with BPH and PCa; to correlate clinical, biochemical and histopathological findings in the above patients. Methods. PSA levels were detected by Chemiluminescent assay; serum calcium – by Modified Arsenazo method; serum acid phosphatase – by Doumas et al method; and Alkaline phosphatase – by Lowry et al method. Results. Present study found high levels of total PSA in BPH and PCa. Levels of free PSA were high in BPH as compared to PCa rate. Free/Total PSA ratio is reduced considerably in PCa as compared to BPH. Serum acid phosphatase and alkaline phosphatase were considerably higher in PCa as compared to BPH. Serum calcium levels did not show significant difference in control and study groups. Conclusions. It was established that patients with PCa have a greater fraction of bound PSA and a lower percentage of free PSA than in those without PCa. Therefore, in clinical practice Free/Total PSA ratio helps clinicians to decide if a biopsy is necessary. Objectives: The study was carried out with the following objectives: to estimate free, total PSA levels and calculate Free/Total PSA ratio in patients with BPH and Carcinoma Prostate, to study the serum levels of calcium, acid phosphates, and alkaline phosphatase in patients with BPH and PCa. and to correlate clinical, biochemical and histopathological findings in the above patients. Methods. Free and total PSA levels were detected by  Chemiluminescent assay; Serum Calcium was detected by Modified Arsenazo method. Serum  acid phosphatase was detected by Doumas et al method and Alkaline phosphatase were detected by Lowry et al  method Results: Present study found high levels of Total PSA in BPH and PCa. Levels of free PSA were high in BPH as compared to PCa ate. Free /Total PSA ratio is reduced considerably in PCa as compared to BPH. Serum acid phosphatase and alkaline phosphatase were slightly raised in PCa as compared to BPH. Serum calcium levels did not show a significant difference in control and study groups. Conclusion: We concluded that patients with PCa have a greater fraction of bound PSA and a lower percentage of free PSA than in men without PCa. There was a negative correlation found between the free/total PSA ratio and the histopathologic findings. The lower the ratio higher is the grade of malignancy. Therefore in clinical practice Free/Total PSA ratio helps clinicians to decide if a biopsy is necessary

Background: The aim of this study was to compare consequences in single and triple testicular biopsy by biopty gun in pubertal rats using histological and immunohistochemical analysis. Methods: Thirty-two Sprague-Dawley male rats were used as the experimental model. The rats were randomly divided into three study groups. The rats from the first group (n = 12) received a single-biopsy of upper pole of the left testis, while the rats from the second group (n = 10) received triple-biopsy of upper and lower poles and lateral surface of left testis. The third group (n = 10) was a control group. On the eightieth day after the biopsy in all rats bilateral orchiectomy and funiculectomy were performed to obtain testicular tissue and sperm for analysis. The consequences of the puncture were observed by pathohistology, immunohistochemistry and semen analysis. Results: The results of the study showed lower percentage of sperm count (14.5 mill/mL vs. 16 mill/mL, p = 0.130), sperm motility (24.6% vs. 32.7%, p > 0.05), abnormal sperm (30% vs. 27%, p > 0.05), atrophic tubules (21% vs. 6%, p < 0.001), volume (1.7 mL vs. 2.28 mL, p < 0.01) and apoptotic index (1.56 vs. 1.19, p = 0.650) in the testes with a triple-biopsy compared to the testes with a single-biopsy. Semen analysis showed a borderline significant difference between the group with triple-biopsy where sperm count was lower than it in the control group (14.5 mill/mL vs. 17.5 mill/mL, p = 0.05). A single-biopsy has little effect on the testis, especially on overall fertility. A triple-biopsy showed higher degree of the testicular damage but without a significant impact on overall fertility. Semen analysis showed that single- and triple-biopsies did not have a significant effect on sperm count, motility and morphology. Conclusion: Biopty gun procedure is a cheap, simple and reliable method for testicular biopsy in rats without a significant effect on sperm count, motility and morphology.

Serum levels of bone-origin alkaline phosphatase and of tartrate-resistant acid phosphatase were measured in Caucasian women aged 41–69 years who had volunteered for bone densitometry. Bone alkaline phosphatase and tartrate-resistant acid phosphatase were inversely correlated with vertebral bone density and with femoral neck bone density. Bone alkaline phosphatase and acid phosphatase were also significantly correlated, consistent with the concept of ‘coupling’ between osteoblast and osteoclast activity.

Rod Fracture

Backgrоund. Rod fractures are one of the specific complications of spinal deformity surgery. The number of publications on this topic is small, and the conclusions are often contradictory. Aim. The aim of this study is to analyze the current situation concerning the problem of fractures of the rods in spinal deformities of various etiologies in terms of frequency and risk factors for this complication. Materials and methods. The study included 3,833 patients who underwent operations between 1996 and 2018. The inclusion criteria of being over 10 years of age with no history of spinal surgery were applied. Results. Fractures of metal implant rods were detected in 85 patients out of a total of 3,833 (2.2%). There was a significant difference between the groups of idiopathic and congenital scoliosis patients. A rod fracture in 62 of the 85 patients was the reason for reintervention to restore integrity with a connector or a full replacement. An increase in BMI by one raised the chance of a fracture by 1.07 times (p = 0.019). Increasing the age by one year increased the possibility of a fracture by 1.03 times (p = 0.039). A statistically significant association of the ventral stage of surgical treatment (discectomy and interbody fusion with autologous bone) where no fracture was detected (p = 0.403) was revealed. Being over 15 years old a statistically significant predictor was in the group under 20 years of age (p = 0.048). For BMI, there was no statistically significant threshold for fracture probability in the group under 20 years of age. It was confirmed that a hybrid fixation system produced a significantly lower percentage of complications than a hook system. A systematic literature review of sources on this topic included international databases (Scopus, Medline, and Google Scholar) as well as investigating the publications contained in the reference list. Conclusions. Rod fractures during surgery for spinal deformities of various etiologies are one of the typical complications. Fracture frequency in large study groups is small. The risk of developing this complication rises with both increasing BMI and patient age, although there is no statistically significant threshold for BMI relative to the chances of fracture in the group up to 20 years of age. Modern reticular systems of attachment of the endocorrector to the vertebral structures can dramatically reduce the risk of rod fracture during the postoperative period.

Background: Deficiency of 25 hydroxyvitamin D has been linked with predisposition to autoimmune disorders. Also, vitamin D has been found to be a causal factor in many autoimmune diseases. Objective of the study was to investigate vitamin D status in children with autoimmune thyroiditis attending endocrinology OPD at a tertiary centre in southern India.Methods: It is a case control study done in which 75 children (70 female, 5 male) with age and sex matched healthy controls were chosen. Free thyroxine, TSH, anti TPOAb, anti TGAb, 25 hydroxyvitamin D, serum calcium, phosphorus, alkaline phosphatase levels were estimated in both cases and control subjects. Children with anti TPO or anti TG positivity were divided into four groups based on their level of antibody titers.Results: The mean age in cases was 9.8±0.34 years. 25(OH)D levels were significantly lower in cases (15.07±1.14 ng/ml) compared to controls (17.82±1.13 ng/ml) (p<0.0006). Mean serum calcium levels in cases (9.35±0.16 mg/dl) were significantly lower when compared to controls (9.73±0.14 mg/dl) (p<0.0005). Similarly mean serum alkaline phosphatase level in cases (184.97±11.10 IU/L) were significantly elevated when compared with controls (122.37±6.82 IU/L) (p<0.0001). However, there was no significant difference in serum phosphorus levels between cases (4.42±0.10 mg/dl) and controls (4.43±0.14 mg/dl) (p=0.83). There was no significant difference in vitamin D level among the groups in both anti TPO (p< 0.283) and anti TG (p<0.148).Conclusions: The significant decrease in vitamin D levels in cases signifies that 25(OH)D may be an independent causal factor related to the autoimmunity in thyroid diseases.

Backgroundː whereas that systemic inflammation (SI) affects 40–60% of patients on hemodialysis (HD) is characterized by serum C-reactive protein (CRP) level elevation or proinflammatory interleukin production or both. We evaluated the association between SI and total (tPSA) and free PSA (fPSA) in patients on HD with tPSA <4ng / ml. Methodsː Sixty patients with chronic kidney disease (CKD) undergoing HD and 20 controls were included. Inclusion criteria were patients aged 18-60 years; tPSA < 4 ng/mL without clinically detectable prostate cancer; and patients undergoing HD for >6 months. Patients were excluded if they had local infections or SI. Hs-CRP was measured using turbidimetry, and tPSA and fPSA levels using immunochemoluminescence. Overall, 27 patients had inflammation (hs-CRP >5 mg/L) and 33 had no inflammation (hs-CRP was ≤5 mg/L). In the control group, hs-CRP was ≤ 1 mg/L. Resultsː there was no significant difference in mean levels among groups 3 and 4 for age (p=0,058), tPSA (p=0,74) and fPSA (p=0,30). The SI did not promote differences between groups 1, 2 and 4 for the levels of tPSA (0,71 ± 0,18  vs   0,67 ± 0,15  vs  0,67 ± 0,11; p=0,69) and fPSA (0,34  ±  0,01  vs  0,34  ±  0,01  vs   0,35  ±  0,01, p= 0,59) . As well as maintained no correlation with tPSA and fPSA (p>0,05). Conclusionː The systemic inflammation in hemodialytic patients without clinically detectable cancer (PSA<4ng/ml) is no associated with changes fractions of tPSA and fPSA.

Abstract We describe enzymatic fluorometric methods for determining activities of serum alkaline phosphatase and of serum acid phosphatase in solution and on silicone rubber pads. 4-Methylumbelliferone phosphate is used as substrate, in either tris(hydroxymethyl)aminomethane or citrate buffer. In solution, the reaction is measured at 37 °C in a 3-ml Pyrex cuvette. Measurements on the pads are also made at 37 °C, after establishing a stable substrate film by lyophilizing all reagents on the surface of the pads. Only 20 to 30 µl of substrate solution, 50 µl of buffer solution, and 1 to 10 µl of blood are necessary, making a total volume of 51 to 60 µl for each assay. The rate of appearance of the fluorescent 4-methylumbelliferone liberated from 4-methylumbelliferone phosphate by the enzymatic action is measured and equated to enzyme activity. Calibration plots of the change in fluorescence per minute vs. enzyme activity for measurements in solution and on pads show a good proportionality in the range of 30.8 to 633 U/liter for alkaline phosphatase and in the range of 0.265 to 5.3 King— Armstrong units for acid phosphatase, indicating the usefulness of these methods in the clinical laboratory.

Basal cell carcinoma (BCC) is the most common dermatological neoplasms in Caucasian populations. In Mexico, a prevalence of 3.9 per 1000 habitants is estimated. Recently, the macrophage migration inhibitory factor (MIF) has been related to different types of cancer. Therefore, this study aimed to investigate the genetic association of haplotypes of [-794(CATT)5-8/-173G>C]MIF gene polymorphisms and its soluble levels in BCC. A total of 360 individuals were recruited for the study, that is, 180 of the total amounts were patients with BCC histologically confirmed and the remaining 180 individuals were identified as control subjects (CS). Both polymorphisms were genotyped by PCR and PCR-RFLP (restriction fragment length polymorphism), and MIF serum levels were measured by ELISA kit. A borderline difference was found between the 55 genotype and the susceptibility to BCC (5.6% vs 1.7% in BCC and CS, respectively, OR=3.7 and p=0.04). Furthermore, the haplotype 7G showed a significant association with BCC (p=0.02, OR=1.99). Concerning MIF soluble levels, patients with BCC showed a media of 2.1 ng/mL and CS showed 4.4 ng/mL, the comparison between groups was significant (p<0.01). Our findings suggest that the 55 genotype and the haplotype 7G are associated with the susceptibility to BCC; furthermore, a significant difference was found between MIF soluble levels in both study groups.

Abstract Background The early detection of bone metastases is very important in prostate cancer follow-up. This study aimed to compare conventional tumor markers, namely free prostate-specific antigen (free PSA), total prostate-specific antigen (total PSA), free PSA/total PSA ratio, alkaline phosphatase (ALP) values, Gleason scores and 99 m Tc-MDP bone scintigraphy findings in the prediction of bone metastases in prostate cancer. Methods In total, 175 patients with prostate cancer who underwent whole-body bone scintigraphy were included in the study. All selected scintigraphic studies were reprocessed. Free PSA, total PSA, free PSA/total PSA ratio, alkaline phosphatase (ALP) values and Gleason scores of patients were recorded. Results The results of our study show that the presence of bone metastasis correlates very weakly with free PSA/total PSA ratio (rho = 0.179), weakly with total PSA (rho = 0.318) and Gleason score (rho = 0.382), moderately with ALP (rho = 0.539), free PSA (0.416). Only ALP variable had a diagnostic value and ALP cutoff value was 76.50 IU/L, with 80% sensitivity and 82.1% specificity. Conclusion According to the results of our study; the free PSA, total PSA, free PSA/total PSA ratio and Gleason score values were not considered as a reliable parameter in the prostate cancer cases follow-up for bone metastasis development. Only ALP had a diagnostic value and ALP cutoff value was 76.50 IU / L with 80% sensitivity and 82.1% specificity in predicting bone metastases in prostate cancer.

This case case control study was undertaken to see if there is any association of serum Zinc level with histologically diagnosed prostatic cancer patients. Also to re-establish the importance of estimation of serum Prostate specific antigen PSA, (Total, Free and ratio between free and total) in prostate cancer patients. It was evident from the present study that serum Zinc level has got statistically significant difference between control and prostate cancer patients (p<0.000),. Total PSA and ratio of free and total PSA was also significantly different between control and prostatic cancer patients (p<0.04 and 0.006 respectively). However no significant difference was observed in free PSA level between this two groups (p<0.282).It was concluded from the present study that serum Zinc level could be an adjuvant laboratory test in the diagnosis of prostate cancer and can be started as a routine test in case of suspected prostatic cancer. Also total PSA level and ratio of free and total PSA not free PSA should be done and correlated for diagnosis of prostate cancer.
