Purpose: To present our experience with laparoscopic management of the non-palpable undescended testis. Patients and Methods: Between Nov. 2010 and Oct. 2012, 47 non-palpable testes in 41 patients were evaluated prospectively by laparoscopy. The age of the patients at the time of surgery varied from 1 to 9 years with a mean age of 2.85 years. Testicular viability and location were evaluated by physical examination and Doppler ultrasonography after 1 and 3 months. Results: Out of 49 testicular units, 47 (95.9%) were successfully treated by laparoscopic orchiopexy. 45 testicular units (91.8%) were treated by one-stage laparoscopic orchiopexy, 2 (4.1%) were treated by two-stage laparoscopic orchiopexy and 2 (4.1%) diagnosed as vanishing testis with detection of blind end spermatic vessels and vas deferens during laparoscopy. Physical examination and Doppler study demonstrated that 46 of 47 testes (97.9%) were viable and 45 of 47 (95.7%) were located in the lower scrotum and 2 of 47 (4.3%) in the upper scrotum at the end of follow-up. Conclusion: The laparoscopy is a reliable technique for diagnosis and treatment of the non-palpable intra-abdominal testis with high success and survival rates of the testes.

The aim of this study was to evaluate the effect of Lactobacillus acidophilus（LAC）, exogenous enzymes of ZAD（exogenous enzyme preparation） or their combination on feed conversion, and dressing of rabbits fed different treatments of sugarcane bagasse（SCB）. Five rations were allotted randomly to five groups of New-Zealand White（NZW） rabbits（n=10） with initial live body weight of（838±42.4） g and 5 weeks of age. Rabbits were fed on diets with different sources of fiber as follows,（i） a control diet composed of 100% berseem hay and 0% SCB,（ii） 50% berseem hay and 50% untreated SCB（USCB）,（iii） 50% berseem hay and 50% SCB treated with L. acidophilus（LAC）,（iv） 50% berseem hay and 50% SCB treated with ZAD（ZAD）, and（v） 50% berseem hay and 50% SCB treated with a combination of LAC＋ZAD（LZ）. Treatments of SCB with L. acidophilus, ZAD and LAC＋ZAD had the highest feed conversion ratio than both USCB and control. The dressing percentage of rabbits that fed the LAC and LZ diets was higher（P〈0.05） compared with that in the other groups. Performance index（PI） for LAC group was improved（P〈0.05） compared to that for the other groups; however, PI for USCB group was the lowest（P〈0.05）. It could be concluded that treating SCB with L. acidophilus, exogenous enzymes of ZAD or their combination improved feed conversion and performance with more positive effects with L. acidophilus than the other treatments.

A 40-years-old female patient with severe right facial pain with a throbbing component along the mandibular division of the trigeminal nerve resistant to medical management. Continuous inferior alveolar nerve block with local anesthetics using an indwelling catheter provided a complete pain resolution for the patient for 2 weeks, after which the catheter got infected and was removed. A trial of balloon occlusion of the right internal maxillary artery provided complete resolution of the throbbing component of the patient’s pain. This was followed by permanent embolization with multiple coils.

Some pelvic pain syndromes are very resistant to medical treatment. Several studies have demonstrated that sacral neuromodulation, which has been successfully used for the treatment of bladder dysfunction, incontinence, urinary retention and urinary frequency [1]-[3], can be successfully used for the treatment of chronic pelvic pain [4]-[7]. Several studies have also demonstrated significant involvement of dorsal column pathways in the transmission of visceral pelvic pain [8] and the successful use of spinal cord stimulation for the treatment of chronic pelvic pain [9]. We report three cases of severe chronic pelvic pain that failed conservative treatment modalities. Placement of a combined sacral nerve roots stimulator and a low thoracic spinal cord stimulator resulted in a significant pain relief and improvement in daily life activities. We believe that this combination may help patients suffering from chronic pelvic pain resistant to medical management.
