Elastography to assess the effect of varicoceles on testes: a prospective controlled study.

Varicoceles are the most common and treatable cause of male infertility. The pathophysiology of varicoceles primarily includes elevated temperature, adrenal hormone reflux, gonadotoxic metabolite reflux, altered testicular blood flow, antisperm antibody formation and oxidative stress. The diagnosis of a varicocele is mainly clinical. However, a Doppler ultrasound is used to obtain clinical data and to more accurately measure testicular size. Acoustic radiation force impulse (ARFI) is an additional technique to simultaneously show different areas with different densities in a colour-coded image and a B-mode or greyscale image. This can be used for structural analysis of testicular tissue and has become an additional method for detecting pathologic tissue alterations. We enrolled 30 patients who had clinically diagnosed with left varicoceles and male infertility (Group 1). All patients were evaluated by history taking, physical examination, a spermiogram and an endocrine profile. Thirty control patients (Group 2) were randomly chosen from patients who had applied to an andrology clinic for infertility; their physical examinations and laboratory results showed normal findings. Mean elastography results were significantly different between the groups, and significantly lower in patients who had varicoceles. The relationship between hormonal profiles and elastography parameters was calculated as statistically significant negative correlations between FSH and elasticity. Additionally, a negative correlation was determined between varicocele grade and elasticity of testes. In conclusion, our prospective study showed that ARFI imaging may be more useful than palpation for determining early damage of testicular structure by varicoceles.

Effect of spermatic vein ligation on seminal total antioxidant capacity in terms of varicocele grading.

We aimed to assess the effect of spermatic vein ligation on seminal total antioxidant capacity (TAC) in patients with varicocele. Twenty infertile male patients with varicocele and 20 normal fertile men (control group) were included in the study. All the male patients were diagnosed with primary infertility and varicocele. The patients with varicocele were divided into two groups as nonpalpable (GI) (eight patients) and palpable (GII-III) (12 patients) varicocele groups. All the patients underwent microsurgical spermatic vein ligation. Seminal TAC levels and sperm parameters were evaluated in all the patients. Preoperative sperm count, sperm motility, sperm morphology and seminal TAC levels with equivalent figures 3-6 months after spermatic vein ligation and the same values of the control group were compared. There was a statistically significant increase in the total seminal antioxidant capacity level after spermatic vein ligation, and there was a statistically significant increase in the sperm count, sperm motility and spermatozoa with normal morphology. However, evaluation of the patients for varicocele grade showed a statistically significant increase in the TAC level only in the GII-III varicocele group. Spermatic vein ligation can improve the total seminal antioxidant capacity levels especially in patients with middle and high grade varicocele.

Biochemical evaluation of the therapeutic effectiveness of honey in oral mucosal ulcers.

The aim of this study was to describe and quantify the therapeutic value of honey in oral mucosal ulcers healing in comparison with Glyceroloxytriester (TGO). We also aimed to biochemically evaluate the healing effects of honey which had been collected from the Blacksea region flora on mucosal ulcers resulting in material loss.Thirty wistar rats (240+/-30 g) were enrolled in this study. Excisional wounds were performed in all rats for animal oral mucosal ulcer model. They were randomly allocated to three groups: group 1 was treated with Apitherapeutic agent or honey (0,1 ml, 2x1), group 2 was treated with TGO (0,1ml, 2x1) locally, Group 3 served as the control group.Following the surgical procedure on day 7, biopsy specimens were taken from right buccal mucosa and on day 14 biopsy specimens were taken from left bucal mucosa in all rats. Afterwards, hydroxy pyroline levels were measured. Data were analyzed statistically.There was no statistically significant difference between Group 1 and 2, and also between Group 2 and 3, but there was statistically significant difference between Group 1 and 3 on day 7. There was no statistically significant difference between Group 1, 2 and 3 on day 14.

Effect of different analgesics on pain relief during extracorporeal shock wave lithotripsy.

BACKGROUND/AIM: The aim of this study was  to compare  three drugs for pain relief during shock wave lithotripsy (SWL). MATERIALS AND METHODS: Seventy six male patients that were treated for renal stones with SWL were included in this study. They were randomized into four groups. A different treatment protocol was used for each group.  Intramuscular (IM) diclofenac 75mg was given in group 1 (n=20), dexketoprofen, 50mg, IM in group 2 (n=20) and hyoscine 10 mg plus paracetamol 500mg, orally in group 3 (n=20). In group 4 (control, n=16) saline solution   was given 30 min before SWL. Pain during SWL was assessed using the 10-score linear visual analogue pain scale (VAS) and was compared among groups. Age, weight, height, body mass index (BMI), stone size, stone location, duration of SWL, total shock waves performed and mean energy level (kV) for each patient were recorded. A p value of <0.05 was considered statistically significant. RESULTS: The mean patients' age was 45.4 ± 12.9 years. The highest VAS value was observed in Group 4 (8.4 ± 1), and the lowest  in Group 1 (6.25 ± 2.2).  Statistically significant  difference was noted  only when Group 1 and Group 4 were compared. The remaining groups provided similar results and there were no significant statistical differences according to VAS values. Other parameters were similar  in all groups. CONCLUSION: In conclusion, this study shows that reducing the pain with a single dose injection of intramuscular diclofenac sodium before SWL is superior compared to others.

Diagnosis and management of congenital neonatal chylous ascites.

BACKGROUND: Congenital chylous ascites is a rare condition that constitutes a challenge for the physician. It is defined as the accumulation of chyle into the peritoneal cavity in infants younger than 3 months. This condition is often refractory to therapy and it is responsible for serious malnutrition and immunological deficiency because of the loss of proteins and lymphocytes. MATERIAL AND METHODS: Four cases of congenital neonatal chylous ascites, were treated by our staff during the last two years. One case was treated conservatively and three with laparotomy. Two of them had intraabdominal cysts that were excised and one was treated with ligation of the left lumbar lymphatic trunk and cisterna chyli and the use of fibrin glue. RESULTS: All four cases were treated successfully. On follow up tests no one showed recurrence of the ascites. All children, except the one that treated conservatively and also had other problems due to prematurity, are growing up normally. CONCLUSIONS: Congenital chylous ascites is a complex condition. Its diagnostic evaluation is difficult and its therapy of long duration. Conservative treatment is in most cases the initial choice, but when it fails, exploratory laparotomy could provide a successful alternative.

Prevention of post-operative nausea and vomiting in children--a prospective randomized double-blind study.

BACKGROUND/PURPOSE: Post-operative nausea and vomiting (PONV) are common complications related to surgery and anaesthesia. The aim of this study was to assess whether sevoflurane, with or without the use of an antiemetic such as ondansetron, increases or not the incidence of PONV in children. METHODS: One hundred and ten children, 2 months to 14 years undergoing inguinal hernia, hypospadias and penile deformity repair, were randomly allocated into one of two groups, according to whether they received ondansetron or placebo (47 vs. 63). Induction and maintenance of anaesthesia was with Sevoflurane in both groups. Regional anaesthesia was performed on all children (inguinal nerve, penile or caudal block). No opioids were used. In post-operative period, children were assessed for PONV, every 4 h for the first 24 h. RESULTS: Vomiting was very low in both groups (8 cases: 7.3%). No significant statistical difference of post-operative nausea (p = 0.296) and vomiting (p = 0.462) (Fisher's exact test) was found between the group that received ondansetron and the placebo group. CONCLUSION: We found that the use of ondansetron did not change the incidence of PONV, the avoidance of opioids and the adequate analgesia may contribute to this. Post-operative oral intake of liquid, (within the first 4 h), increases the risk for PONV.
