RESUMEN

Antiseptic agents used in the postoperative period affect the functions of many tissues in the body, including the testicles. In this study, the effect of dressings administered with different antiseptic agents on testicular functions in rats that underwent abdominal incisions was investigated. A total of 48 Sprague-Dawley rats were used in the study. Each of the rats in the study group underwent a 4 cm-long skin and muscle operation. The incision was then stitched immediately. Antiseptics, hemp seed oil, hemp leaf oil, and cannabidiol oil were then administered to the rats for 10 days to provide antisepsis. The rats were sacrificed 24 hours after the last administration, and testicular tissues were removed. Testicular tissues were used for histopathological examination and biochemical analysis, while epididymal tissue was used for sperm analysis. According to the results, the MDA level in the antiseptic-administered group was higher than in the other experimental groups (p<0.05). Levels of SOD, CAT activities, and GSH content were found to be lower in the antiseptic group than in the hemp seed oil, hemp leaf oil, and cannabidiol oil groups (p<0.05). In testicular histology, the SEED group had the highest Johnsen score, and the antiseptic group had the lowest score (p<0.05). While JAK, P-JAK2, STAT3, PSTAT3, and NF-κB were generally higher in the antiseptic group compared to the other groups, they were lower in the SEED group. Additionally, sperm total motility rate and epididymal sperm density were highest in the SEED group (p<0.05). As a result, it was determined that cannabidiol seed oil had a good effect on testicular histology and sperm quality in male rats during the wound healing process.

RESUMEN

The aim of the present study was to determine the effects of Luteolin (LUT) on semen quality, oxidative stress, apoptosis, acrosomal integrity, mitochondrial membrane potential and dead sperm ratio in rabbits. Ejaculates from six New Zealand rabbits were collected, evaluated and pooled. The pooling was divided into five groups as control (no additive) LUT 25 µM, LUT 50 µM, LUT 100 µM and LUT 200 µM and LUT added. It was then filled into a falcon tube with Tris-based extender at a final concentration of approximately 35 x 106 spermatozoa. Diluated rabbit semen samples were drawn into frozen and thawed. Frozen semen straws were thawed at 37°C in 30 seconds. According to our findings, no statistical difference was found between all doses of luteolin and the control group in the CASA (computer assisted sperm analysis) analysis performed at 4°C. However, total motility, progressive motility and rapid sperm percentage were found to be higher in the frozen and thawed rabbit semen at a dose of LUT 50 µM compared to the other groups (p⟨0.05). While amplitude of lateral head displacement (ALH) and beat cross-frequency (BCF) values were found at the lowest dose of LUT 200 µM, a statistically significant difference was observed between the other groups. When the flow cytometry results were examined, no statistical difference was found between the rate of dead sperm, acrosomal integrity, mitochondrial membrane potential and apoptosis rate. Morever, the H2 O2 percentage was found to be lower in all experimental groups compared to the control group (p⟨0.001). In conclusion, the addition of LUT in long-term storage of rabbit semen provided a protective effect for spermatozoa with its antioxidative properties against damage caused by cryopreservation.

RESUMEN

BACKGROUND: Amides are low molecular weight cryoprotectants. N-methylacetamide (MA) is one of the cryoprotectant agents in this group. OBJECTIVE: To investigate the cryoprotective effect of MA in rabbit semen. MATERIALS AND METHODS: For this purpose, six ejaculates from six New Zealand rabbits were collected and pooled using an artificial vagina. Pooled semen was divided into four equal parts and diluted with TCG+ egg yolk. CPA was added to form the following groups: Control with 6% DMSO; Group 1 with 1% MA; Group 2 with 2% MA; and Group 3 with 3% MA. After the addition of CPA, the semen eqilibration procedure was started. Sperm were then drawn into 0.25 mL straws, frozen by automatic semen freezing and stored in a liquid nitrogen container. Pipettes were thawed after 24 h and analyses were performed. RESULTS: Total, progressive and rapid motility values of the Control group were higher than those of the MA groups (p<0.05). However, there was no statistical difference between the Control and Group 2 in terms of these parameters. While there was no statistical difference between the groups in terms of acrosome damage and mitochondrial membrane potential, the best results were observed in Control, Group 2, Group 1 and Group 3, respectively. When we compared all groups, no difference was found in terms of MDA, CAT and GSH-Px. There was a statistical difference between Group 3 and the Control in terms of GSH level (p<0.05). CONCLUSION: DMSO appeared to be more useful for the cryopreservation of rabbit semen compared to MA. Doi.org/10.54680/fr23610110812.

RESUMEN

AIMS: The aim of this study is to evaluate the effect of the diode laser used for dentin sensitivity on the clinical success of non-carious cervical lesion (NCCL) restorations restored with different adhesive systems. METHODS: 20 NCCLs were restorated with Universal Single Bond (Self Etch) (3M, USA) and Grandio (Voco, Germany), 20 NCCLs were restorated with Universal Single Bond (Total Etch) and Grandio. After diode laser application, 20 NCCLs were restorated with Universal Single Bond and Grandio, 20 NCCLs were restorated with Universal Single Bond (Total Etch) and Grandio. The restorations were clinical evaluated by two examiners at baseline, for 6 and 18 months using modified United States Public Health Service (USPHS) Criteria. Chi-square test was used for statistical analyse. RESULTS: The lowest rates of retention was found in the Group 1. There was no statistically significant difference among the groups in marginal discoloration, marginal integrity, sensitivity (P > 0.05). CONCLUSION: Diode laser application prior to the restoration of teeth with NCCL don't reduce the retention rate of restorations, may reduce hypersensitivity and may affect the success of restoration. However, further laboratory and clinical studies are required.

RESUMEN

In this study, it was aimed to investigate the changes in testicular tissue and cell count, testicular oxidative stress and some metabolic blood parameters of male broiler Japanese quails fed with high energy diet and milk thistle (Silybum marianum) seed. One hundred-twenty male 15-day-old Japanese quail chicks were divided into 4 equal groups with 30 each. The applications in each group were repeated 3 times with 10 animals each. Control group was fed with basal diet. Milk thistle seed group was fed with diet including 1% milk thistle seed. High energy diet group was fed with high energy diet including 10% corn syrup. High energy diet + milk thistle seed group was fed with high energy diet including 10% corn syrup along with 1% milk thistle seed. The feeding period in all groups was 35 days. When the quails reached 50 days old, a total of 48, 12 from each group (4 from each replication) were euthanized and blood samples and testes were collected. Compared with the control group, significant increases in body weight, serum cholesterol and glucose level, aspartate aminotransferase activity and testicular malondialdehyde level; however, significant decreases in serum testosterone level, testicular glutathione peroxidase activity, counts of round and elongated spermatid and sperm as well as histopathologically, significant decreases in seminiferous tubular diameter and seminiferous epithelium thickness, and marked disorganization in germinal cells were determined in quails fed with high energy diet. It was observed that almost all of the disturbances in testicular tissue, cell number, oxidant-antioxidant balance and metabolic blood parameters caused by feeding with high energy diet were significantly prevented by supplementation of milk thistle seed to the diet with high energy. On the other hand, alone milk thistle seed and high energy diet + milk thistle seed administrations decreased body weight in comparison to control and high energy diet groups. As a result, feeding with high energy diet causes disturbances in testes of male quails by affecting liver metabolic functions and testicular oxidant-antioxidant balance, but milk thistle seed addition to diet plays a protective role.

RESUMEN

The aim of this study was to determine the efficacy of single versus repetitive injection of lignocaine into the carpal tunnel for the management of carpal tunnel syndrome. The 42 patients included were randomly assigned to two Groups: group 1 was injected with 4 mL of 1% lignocaine once and Group 2 was injected with 4 mL of 1% lignocaine twice a week for 2 weeks. Clinical and electrophysiological evaluations were performed at the study onset, and at 6 and 12 weeks following the final injection. Initially, the groups were similar with respect to clinical and electrophysiological findings. All parameters in Group 2 improved 6 weeks post treatment (p < 0.05), and these improvements persisted at 12 weeks post treatment (p < 0.05). Repetitive local lignocaine injection was effective in reducing the symptoms of carpal tunnel syndrome and improving electrophysiological findings.

RESUMEN

Bisphosphonates are inorganic pyrophosphate analog which accumulate on the bone surface, cause osteoclast apoptosis, and inhibit bone resorption. The nitrogen-containing bisphosphonates continue to be the drug of choice for the treatment of osteoporosis in both men and women. Although histomorphometric studies including bone biopsies have not shown any evidence of microcracks, recent studies have revealed that potent bisphosphonates are responsible for the oversuppression of bone turnover leading to microdamages, reduced bone strength, and increased fracture risk. There are individual cases reporting atypical femoral fractures and severely suppressed bone turnover along with long-term (≥ 5 years) use of biphosphonates. In this study, we report on a 74-year-old woman with a history of continuous alendronate use for nearly 16 years who presented to the emergency department with right proximal humerus and left femur fracture.

RESUMEN

BACKGROUND: There is a wide spectrum of treatments available for actinic keratosis (AK). Topical diclofenac sodium and imiquimod are two topical treatments, which are noninvasive, easily applied, well-tolerated and effective. AIM: To compare the effects of topical 3% diclofenac sodium plus hyaluranon (DFS) gel, 5% imiquimod (IMQ) cream, and base cream (BC) in patients with AK. METHODS: In total, 61 patients, diagnosed clinically and histopathologically as having AK, were randomized into three treatment groups to receive topical treatment with either DFS (twice daily for 12 weeks), IMQ (twice per week for 16 weeks) or BC (twice daily for 12 weeks). Patients were evaluated clinically at 0, 4, 8, 12, 16, 20 and 24 weeks. Treatment efficacy was assessed by Total Thickness Score (TTS) and Patient Global Improvement Index (PGII). RESULTS: Complete clearance rates for DFS, IMQ and BC at the end of the treatment and at the end of the total follow-up period were 19.1%, 20% and 0%, and 14.3%, 45% and 0%, respectively. Although the average TTS value of the DFS group at week 24 was significantly higher than that of the IMQ group, the PGII values were not significantly different. CONCLUSIONS: Although DFS and IMQ each had considerable efficacy in the treatment of AK, the efficacy of DFS seemed to decrease after cessation of treatment.

RESUMEN

BACKGROUND: No single effective topical treatment is available for treating all pathogenic factors causing acne vulgaris (AV). Salicylic acid (SA), tretinoin (all-TRA) and clindamycin phosphate (CDP) are known to to be effective agents depending on their comedolytic and anti-inflammatory properties. OBJECTIVE: To compare the efficacy and tolerability of SA and CDP combination (SA+CDP) with all-TRA and CDP (all-TRA+CDP) in patients with mild to moderate facial AV. METHODS: Forty-six patients aged between 18 and 35 years were enrolled in a 12-week prospective, single-blind, randomized and comparative clinical study. Efficacy was assessed by lesion counts, global improvement, quality of life index and measurement of skin barrier functions. Local side effects were also evaluated. RESULTS: Both combinations were effective in reducing total lesion (TL), inflammatory lesion (IL) and non-inflammatory lesion (NIL) counts and showed significant global improvement as evaluated by the investigator. At the end of the study, there was no significant difference between the two groups in terms of all lesion counts. In addition, TL counts decreased faster in the all-TRA+CDP group compared with those in the SA+CDP group, with a significant difference between the two groups occurring as early as 2 weeks. Safety evaluations demonstrated that the incidence of mild to moderate side effects generally peaked at week 2 and declined gradually thereafter. Both combinations did not have an effect on stratum corneum hydration, although skin sebum values decreased with SA+CDP treatment. CONCLUSIONS: Combination of SA+CDP and all-TRA+CDP was effective in decreasing lesion counts and well tolerated with minimal local cutaneous reactions in patients with mild to moderate AV.

RESUMEN

BACKGROUND: Because of their clinical similarities, pigmented basal cell carcinomas (BCCs) can be confused with melanocytic pigmented lesions especially with melanoma. Since special dermoscopic features have been described for pigmented BCCs, dermoscopy is accepted as a useful tool for the diagnosis of pigmented BCCs. OBJECTIVE: To investigate dermoscopic and corresponding histopathologic features of BCCs and to evaluate their correlations in pigmented BCCs. METHODS: In this study, 32 pigmented BCCs in 30 patients whose diagnoses were confirmed with clinical and histopathologic features were included. Before the histopathologic evaluation, the lesions were analysed for dermoscopic features. Histopathologic correlations of dermoscopic features of BCCs and the localization of pigment accumulation in tumour mass were investigated. RESULTS: In addition to ulceration, large grey-blue ovoid nests, multiple grey-blue globules, maple leaf areas and arborizing telangiectasia; dermoscopically yellow-brown, whitish-yellow, and black-dark brown colour showed statistically significant correlation with their histopathologic counterparts (P < 0.05). Whitish veil, which is among dermoscopic features of BCCs, did not show significant correlation with its histopathologic counterpart (P > 0.05). It was histopathologically determined that pigmentation is found within the tumour mass as well as in the tumour stroma and in the hyperplastic epidermal melanocytes. CONCLUSIONS: Ulceration, large grey-blue ovoid nests, multiple grey-blue globules, maple leaf-like areas and arborizing telangiectasia, which are specific dermoscopic features for the diagnosis of pigmented BCC, were found to correlate with their histopathologic counterparts. In conclusion, dermoscopy can be described as a valuable tool for the diagnosis of pigmented basal cell carcinomas.

RESUMEN

BACKGROUND: In recent years, lasers have been used in verruca therapy and some successful results have been obtained in some types of verruca. In some of these laser studies, peeling processes have been used to increase penetration. OBJECTIVE: This study aimed to compare the effects of pulsed dye laser (PDL) therapy with the effects of PDL therapy following salicylic acid (SA) application. The purpose of the SA application is to increase the laser penetration by decreasing the hyperkeratosis of verruca vulgaris. METHODS: This controlled study included 66 lesions from 19 patients enrolled in the study. PDL was applied to 33 lesions following 30% SA application twice a day for 5 days, and the remaining 33 lesions underwent PDL therapy. PDL was administered in both groups at 4-week intervals varying from one to five sessions. In the comparison of these two groups, the changes in verruca dimensions were recorded in width x length x height (mm3), and the results of the therapy were evaluated statistically. RESULTS: In both PDL and SA + PDL groups, the regressions observed in the size of the lesions were statistically significant at the end of the fifth session compared with those observed at the onset of the therapy (P < 0.05). At the end of the fifth session, the difference between the two groups was not statistically significant (P = 0.451); however, the clearance rate in the SA + PDL group was more statistically significant than that in the PDL group after the second session (P = 0.049). The complete clearance rate in the SA + PDL group was 54.6% after the second session, but 66.4% in the PDL group only after the fifth session. Complete clearance in the SA + PDL group was observed after 2.2 sessions, and in the PDL group after 3.1 sessions (P < 0.05). CONCLUSIONS: Although there was no difference between the clearance rate of the SA + PDL group and that of the PDL group after the fifth session, adding SA to PDL decreased the number of sessions to a large extent.

RESUMEN

Hereditary multiple exostoses (HME) is an autosomal dominant disorder characterized by the presence of multiple exostoses. Three genetic loci have been identified, of which two (EXT1 and EXT2) have tumor suppressor activity. HME greatly increases the risk to develop sarcoma in the dysplastic tissue. The authors report an 8-year-old girl with HME who developed acute myeloblastic leukemia.

RESUMEN

The nipple and areola diameter of 498 girls aged 8-17 years were studied with the aim of finding measurable criteria for sexual maturation, including breast and pubic hair development during female puberty. All measurements were made holding a transparent ruler on both sides by the same observer. The smaller of the two measurements was used in the analysis. Significantly nipple and areola development occurred between breast stages B1 (2.56 and 14.35 mm), B2 (3.32 and 20.26 mm), B3 (5.21 and 28.84 mm), and B4 (6.28 and 32.03 mm). The nipple and areola diameter were also significantly greater in pubic hair stage (PH)3 (5.05 and 25.24 mm) with respect to PH2 and PH1 (3.46, 2.62 mm and 19.32, 15.37 mm, respectively), in PH5 (6.79 and 35.62 mm) with respect to PH4 (6.55 and 32.56 mm). A significant increase in nipple and areola diameter occurs between premenarchal girls and girls older than 0-2 years postmenarche. Sexual maturation staging by nipple size and by areola size appears to be feasible for female adolescent. However, staging by nipple size does not appear to be feasible for B4 and B5 stage, because the incremental gradations are small.
