ABSTRACT

Objective To evaluate the efficacy and safety of intradetrusor injection of botulinum toxin type A in the treatment of ketamine-related cystitis.Methods A retrospective analysis of clinical data of 36 ketamine-related cystitis patients with intradetrusor injection of botulinum toxin type A treatment in our hospital during August 2010 to December 2015 was conducted, including 31 males and 5 females with a mean age of 25.5 years.All patients had failed to conventional treatment options including cessation of ketamine, antibiotics, M-blockers.At the time of the first injection, patients were injected with 200 U botulinum toxin type A diluted in 15 ml of 0.9% saline into the detrusor muscle at 30 sites, sparing the trigone, under cystoscopic guidance.3-d voiding diary, interstitial cystitis symptom index (ICSI),interstitial cystitis problem index (ICPI), pelvic pain and urinary frequency/urgency symptom score (PUF) were recorded to evaluate the efficacy.The treatment-related complications were recorded.When the efficacy of botulinum toxin type A decreased and the patient's symptoms returned to baseline before treatment, the patient received repeated injections of botulinum toxin type A with the same dose and method as the first injection.Results Thirty-six patients with ketamine-related cystitis were treated with intradetrusor injection of botulinum toxin type A.Sixteen patients received two injection treatments and two patients received three injection treatments.During the follow-up, 3-d urinary diaries, ICSI, ICPI, and PUF showed a significant improvement in outcome at 4 weeks after the first injection.The efficacy of the second and third injection treatment was also remarkable.Three patients developed urinary tract infection after the first injection, and two patients developed urinary tract infection after the second injection.Mild hematuria occurred in 15 patients after the first injection, and mild hematuria occurred in 7 patients after the second injection, which was improved in 1 to 2 days.All patients did not appear acute urinary retention and other adverse drug reactions.Conclusions Intradetrusor injection of botulinum toxin type A could be a safe and effective method for the treatment of ketamine-related cystitis.Repeated injection therapy is still safe and effective.

ABSTRACT

@#Objective To observe the effects of repeated Botulinum toxin type A (BTX-A) injection on lower limb spasticity after stroke.Methods 180 cases with lower limb spasticity after stroke were divided into the treatment group (n=90) and the control group (n=90). The treatment group was treated with BTX-A injection twice in the spastic muscles at interval of 3~6 months, while both the treatment group and the control group accepted the rehabilitation based on the neurodevelopmental therapy. They were assessed with modified Ashworth Scale (MAS), Fugl-Meyer Lower Limb Assessment (FMAL), Berg Balance Scale (BBS), modified Barthel Index (MBI) before each injection, and 3 d, 7 d, 1 month, 3 months after each injection or the same time for the controls. Results There was significant difference in scores of MAS, FMAL, BBS, MBI for the treatment group among before and 3 d, 7 d, 1 month after each injection (P<0.05), but not significant between 2 injections (P<0.05). There was significant difference in scores of all the assessment between the treatment and control group at the same time (P<0.01). Conclusion Repeated intramuscular injection of BTX-A can reduce the spasticity of lower limb after stroke.

ABSTRACT

PURPOSE: To investigate the incidence of complication associated with repeated botulinum toxin chemodenervation in extraocular muscle. METHODS: 47 patients who had taken botulinum toxin chemodenervation from 1996 to November 2001 were reviewed retrospectively. 10 patients had taken repeated injection. Saline diluted botulinum toxin was directly injected into the extraocular muscle through the Teflon coated needle. RESULTS: In 10 patients, 5 patients had complications which were 2 cases of hypertropia, 2 cases of ptosis and 1 case of retrobulbar hemorrhage who was 44 year old woman taken 5 times of botulinum toxin injection. She was successfully treated with lateral canthotomy and cantholysis. CONCLUSIONS: Rate of complication in repeated botulinum toxin chemodenervation was not different from that of single procedure. We experienced one case of retrobulbar hemorrhage in 10 patients with repeated botulinum injection.

ABSTRACT

A number of chronic inflammatory lesions of unknown etiology in man have recentlybeen understood by the mechanism of so called auto-immune disease and a series of experimental study using animals have been extensively undertaken to reproduce the lesion. Experimental chronic inflammatory diseases induced by repeated injection of homologous or heterologous tissue antigen with adjuvant are based upon immunological process and these are readily reproducible. The author has experimentally studied on any allergic destruction of the epididymis of the rat on immunologic process as in other particular organs and tissue. A total of 59 white healthy male rats were divided into 7 major experimental groups of injection as follows. Group 1: six rats, control, injection with normal saline alone. Group 2: six rats, injection with adjuvant only. Group 3: six rats. injection with epididymal tissue only. Group 4: twenty-three rate, injection with rat epididymal tissue plus adjuvant. A. seven rats, sacrificed on the 64th day B. ten rate, sacrificed on the 92nd day C. six rats, sacrificed on the 128thday Group 5. six rate, injection with rat epididymal tissue plus adjuvant plus prednisolone. Group 6: six rats, injection with rabbit epididymal tissue only Group 7: six rats, injection with rabbit epididymal tissue plus adjuvant Injections were given into the abdominal muscle of the rat once s week for 8 weeks as scheduled in the text and the animals of all groups except the group 4, were sacrificed 8 days after the final injection. In the group 4, animals were further divided into 3 subgroups which were sacrificed on the 61st, 92nd and l28th day of the experiment, respectively. The epididymis and other organs of allexperimental animals were studied histopathologically and the following results were obtained; 1. In all rats of the group 1 receiving homologous epididymal tissue with adjuvant, the epididymis revealed relatively marked and significant inflammatory changes. Histopathology included edema, congestion, fibrosis in the interstitial tissue, and infiltration of inflammatory cells mainly composed of lymphocytes, histiocytes, plasma cells and eosinophils. Flattening and hyperplasia of the epithelial cells and cellular exsudation were observed in the tubules. 2. In the group 1, the lapse of time after injection provoked more marked inflammatory changes. Diffusely mild or moderate degree of inflammation observed on 61st day, was changed to diffusely moderate or marked inflammation on 92nd day and then to significantly more chronic lesion with less exsudation and more fibrosis on 128th day. 3. Homologous tissue antigen without adjuvant andheterologous tissue antigen with or without adjuvant caused no inflammatory changes. 4. Inflammatory changes induced by homologous tissue antigen with adjuvant seem to be readily inhibited or prevented by simultaneous administration of prednisolone.
