Laxatives and faecal incontinence in long-term care

Mechanism of action and clinical efficacy of microwave resonance therapy (MRT) was studied in 114 patients with primary osteoarthrosis. It was found that clinical benefit of MRT in primary osteoarthrosis is due to combined positive effect on nonspecific immune reactivity, endogenic intoxication, lipid peroxidation, activity of antioxidant defense system, local immune reactions.     

Randomized trial comparing three forms of pelvic floor repair for neuropathic faecal incontinence

A randomized controlled trial in women with neuropathic faecal incontinence compared total pelvic floor repair (n = 12) with anterior levatorplasty and sphincter plication alone (n = 12) and postanal repair alone (n = 12). Review at 6 and 24 months indicated that results were significantly better for total pelvic floor repair than either of the other procedures. Complete continence was achieved in eight of the 12 patients 2 years after total pelvic floor repair. Only total repair significantly elongated the anal canal. Both total pelvic floor repair and anterior levatorplasty improved sensation in the upper anal canal.     

Surgical repair for supravalvular aortic stenosis: intermediate to long-term follow-up

The prevalence of different malocclusion features was investigated in 396 6-year-old Icelandic children, using the epidemiologic registration method described by Bj?rk et al. in 1964. Girls were ahead of boys with regard to dental stage (P < 0.01). One or more permanent teeth were congenitally missing in 5% of the children. Postnormal occlusion was found in 27% of the boys and in 31% of the girls, and prenormal occlusion was found in 6% and 5%, respectively. Straight terminal plane at the second deciduous molars was found in individuals with either normal or postnormal occlusion. Thus, it can be misleading to use the relation of the terminal planes as a measurement of the sagittal relation between the jaws. The prevalence of hypodontia was much lower than has been reported previously for Icelandic children.     

Mitral valve repair: Intermediate to long-term echocardiographic follow-up

PURPOSE: To study the changes in clear cornea incision size after phacoemulsification and implantation of a three-piece, silicone, foldable intraocular lens (IOL). SETTING: Departamento de Oftalmologia, Clinica Universitaria de Navarra, Pamplona, Spain. METHODS: In this prospective study, phacoemulsification with implantation of a foldable IOL (AMO SI-30NB) was performed in 133 eyes. Surgery was carried out by four surgeons who implanted the IOL with the same forceps. The external incision size was measured before and after phacoemulsification and irrigation/aspiration and before and after IOL implantation. RESULTS: Before phacoemulsification the mean incision size was 3.07 mm; after phacoemulsification and irrigation/aspiration, it enlarged to 3.09 mm (P = .001). The mean incision size before foldable IOL implantation was 3.16 mm, and after implantation it increased to 3.32 mm (P = .0001). When the IOL was less than 22.0 diopters (D), the final incision size was 3.31 mm +/- 0.11 (SD); when the IOL was 22.0 to 26.0 D, the final size was 3.32 +/- 0.01 mm; and when the IOL was 26.0 D or more, the final size was 3.39 +/- 0.08 mm (P = .01). CONCLUSIONS: Phacoemulsification and foldable IOL implantation enlarged the size of the clear cornea incision in this study. The IOL power may be a significant factor in determining the minimal incision size prior to IOL insertion and the final incision size.     

Glutaraldehyde cross-linked collagen in the treatment of faecal incontinence

BACKGROUND: The treatment of faecal incontinence secondary to internal anal sphincter dysfunction is unsatisfactory. The aim of the study was to evaluate the efficacy of anal glutaraldehyde cross-linked (GAX) collagen injections in patients with a surgically incorrectable disorder. METHODS: Seventeen patients were studied: nine had idiopathic faecal incontinence, three had incontinence following haemorrhoidectomy, two following internal sphincterotomy, two following an internal sphincter defect from obstetric injury and one following treatment for fistula in ano. All patients were refractory to conservative treatment and were unsuitable for surgical repair. All had anorectal physiology and endoanal ultrasonography before and after GAX collagen injections. RESULTS: All patients tolerated the injection without side-effects. All patients had an intact external anal sphincter. Following injection, 11 patients showed marked symptomatic improvement. One patient reported symptomatic improvement but remained in clinical grade 3, and two reported minimal improvement. There was no improvement in three patients, but one of these had a repeat injection and showed significant improvement subsequently. CONCLUSION: Injection of GAX collagen in the anal canal is a simple and well tolerated method of treating faecal incontinence due to internal sphincter dysfunction. Early results suggest it provides an easy and reliable alternative to the currently available methods that are often unsuccessful and at best unpredictable.     

Recent advances in the surgical treatment of faecal incontinence

STATEMENT OF PROBLEM: Even though assessments of borderline restorative items in terms of accuracy and interexaminer variation have been reported, no attempt has been made to simultaneously evaluate diagnostic and treatment planning decision using objective normative standards. PURPOSE: This study established the accuracy of caries presence assessment as compared with gold standards, interexaminer agreement in assessment of caries presence and restorative needs, and influences of perceived caries status and restoration quality on treatment planning in borderline restorative situations. MATERIALS AND METHODS: Fifteen senior dental students in Mexico City (66% women; mean age 23.2 years) evaluated predetermined areas in 109 restored and unrestored posterior teeth in an in vitro model. Teeth were subsequently assessed for restoration quality and the presence of enamel and dentinal caries by use of histologic and specific dye techniques. Student's t test, Cohen's kappa, and Pearson's correlation analyses were used to analyze the data. RESULTS: There were significant caries misdiagnoses and substantial overtreatment proposed. In a few instances, teeth were left untreated, but usually they were programmed for restoration. Interexaminer agreement varied markedly and was not high. However, performance while correctly detecting lesions was better than in treatment planning. CONCLUSION: There was a high correlation between a diagnosis of caries and restorative treatment in unrestored teeth; the correlation was lower for restored teeth, although they were allocated to restorative treatment more often. This difference hinged on perceived quality of the restoration, an important factor in the frequency of proposed re-restoration.     

Percutaneous varicocele occlusion: long-term follow-up

We investigated the mechanism of resistance in murine L1210 leukaemia cells selected after treatment with FCE 23762 methoxymorpholinyl doxorubicin: (MMRDX), a methoxymorpholinyl derivative of doxorubicin active in vitro and in vivo on multidrug-resistant (mdr) cells, currently undergoing phase I clinical trials. The resistant subline obtained after repeated in vitro treatments, L1210/MMRDX, is resistant in vitro and in vivo to all tested methoxymorpholinyl derivatives and to cyanomorpholinyl doxorubicin, but shows resistance to morpholinyl derivatives only in vivo or following their activation with rat S9-liver fractions in vitro. L1210/MMRDX cells are sensitive to classic mdr- and altered topoisomerase (AT)-mdr-associated drugs. These cells do not appear to overexpress the mdr1 gene, nor do they exhibit impaired intracellular drug accumulation and efflux or altered levels of glutathione and glutathione S-transferase. The extent of DNA single-strand break formation and, after microsomal activation, of DNA interstrand cross-links after treatment with MMRDX was similar in the parent and the resistant subline. The mechanism of resistance in L1210/MMRDX cells remains to be identified but may prove a novel one, highly specific for this class of mdr-active anthracyclines.     

Vestibular nerve section: long-term follow-up

Vestibular nerve section is considered an effective modality in the treatment of refractory and incapacitating vertigo. Typically nerve section results are described on the basis of short-term follow-up. We have reviewed 41 cases of vestibular nerve section spanning an 18-year period. Although the majority of cases involved classic Meniere's disease, delayed endolymphatic hydrops, vestibular neuritis, and Meniere's syndrome secondary to head trauma were also included. Surgical approaches included translabyrinthine (20 cases), retrolabyrinthine (14 cases), retrosigmoid (six cases), and middle fossa (one case) procedures. Postoperative follow-up time averaged 102 months, with 46% of patients followed for a minimum of 9 years. Results are reported according to standards set forth by the American Academy of Otolaryngology--Head and Neck Surgery. Vertigo was cured or markedly improved in 88% of cases (90% in patients with Meniere's disease) at 18 to 24 months postoperatively. These vertigo results were sustained at the time of latest follow-up. Functional level was also preserved over time despite the development of bilateral symptoms in several cases. The rate of bilateral disease reached 22% of cases. Although vertigo results remained stable, long-term follow-up of successful hearing preservation cases demonstrated deterioration over time. Postoperative continuation of medical treatment is urged to optimize and sustain the vestibular neurectomy result.     

Meniscal repair: outcomes and clinical follow-up

A retrospective study of arthroscopic meniscal repair in 101 consecutive patients was conducted. Sixty-three patients constituted our study group. The arthroscopic technique used for meniscal repair was the inside-out method using malleable cannulas. Forty-five patients were available for clinical examination, with a mean follow-up of 27 months. Tegner and Lysholm scores were comparable to those previously reported for arthroscopic meniscal repair. The HSQ (similar to the SF-36) scores were equal to those from an age- and sex-matched normal population, indicating that individuals with repaired menisci do not have any residual negative effects on global health at mean 26.9 months' follow-up. The physical functioning subscale of the HSQ was found to be sensitive to patient perception of results. Complications included one case of restricted knee range of motion requiring arthroscopy and lysis of adhesions. Overall clinical results were 64% excellent, 27% good, and 9% failure. Age, sex, and length of the meniscal tear had no affect on clinical outcome.     

Infantile eczema: A long-term follow-up study

A 15-17 year follow-up study was conducted on ninety-nine patients who had suffered from infantile eczema. The persistance of the eczema and the occurrence of related conditions were noted. The persistence of eczema was shown to be greater in those patients with a positive family history of eczema and in those who had developed asthma or hay-fever. An attempt was made to see if the persistence of eczema was affected by the position of the child in the family, and some factors provoking relapses were noted. The patients were also questioned with regard to their achievements in academic examinations, and to their social, artistic and sporting activities. The results showed a success rate in examinations not significantly higher than average. It was not possible to show if there is a particular type of atopic personality. There was no constant characteristic in social or artistic patterns. The group as a whole were normal at the milestones of early development, i.e. walking, talking and reading, and also normal with regard to weight and height.     

Whipple's disease: results of long-term follow-up

AIM: To analyze clinical, diagnostic and therapeutic aspects of Whipple's disease. MATERIALS AND METHODS: Diagnostic and therapeutic data are available for 7 patients registered in 1990-1997. The diagnosis was made using intestinoscope SIF-10L ("Olympus"). Biopsies were obtained from the jejunal, duodenal and gastric mucosa. The patients received tetracycline, erythromycin, biceptol, on demand--prednisolone. RESULTS: Whipple's disease was diagnosed 6 years on the average following the first clinical symptoms. In most patients the intestinal symptoms were preceded or accompanied by such extraintestinal symptoms as enlargement of the lymph nodes, lowering of hemoglobin, hypoproteinemia, ESR increase to 40-60 mm/h. To study biopsies from the distal duodenum is the only measure needed for diagnosis of Whipple's disease. In untreated patients PAS-positive macrophages are detectable also in gastric body mucosa. The immediate treatment outcome is favorable. The recurrence was observed only in one patient who had given up taking tetracycline. CONCLUSION: Long-term antibacterial therapy brings the recovery. Primary disorder of the cellular immunity responsible for the disease onset necessitates long-term follow-up of the patients. Control biopsy should be examined once a year.     

Experimental model of pudendal nerve innervation of a skeletal muscle neosphincter for faecal incontinence

BACKGROUND: Faecal incontinence is difficult to treat. A variety of reconstructive procedures has been described, but none is entirely satisfactory. This study evaluated the feasibility of cross-innervating a skeletal muscle neosphincter with the pudendal nerve in a canine model. METHODS: Thirty dogs were rendered surgically incontinent (the pudendal nerve was cut and the external sphincter was partially excised). A neosphincter was then created using the semitendinosus muscle. In ten dogs pudendal nerve transposition (PNT) to the nerve to the semitendinosus muscle was performed. Ten dogs were given a dynamic neosphincter by inserting a pulse generator at 6 weeks. The remaining ten dogs served as controls with passive semitendinosus wraps. Anal manometry was performed before operation and monthly for 5 months. Muscle biopsies, performed at the initial operation and at 5 months, were stained for slow- and fast-twitch fibres, and were examined histologically. RESULTS: At 1 month, mean sphincter function was 32 per cent of the preoperative value in the control animals, 34 per cent in the PNT group and 27 per cent in the electrostimulation group; all dogs were incontinent. At 5 months the mean recovery of sphincter function was 42 per cent of the preoperative value in controls, 100 per cent in dogs with PNT (P < 0.001) and 63 per cent in dogs having electrostimulation (stimulator on) (P = 0.02). Six dogs with PNT had squeeze pressures equal to or greater than preoperative levels. At 5 months the ratio of slow to fast fibres was significantly greater in all dogs (control P = 0.01, PNT P < 0.005, electrostimulation P < 0.001). CONCLUSION: Use of the pudendal nerve to innervate a canine skeletal muscle anal wrap produced a functional anal sphincter that was superior to electrically stimulated and passive wraps.     

Pubovaginal fascial sling for all types of stress urinary incontinence: long-term analysis

PURPOSE: There is a lack of consensus regarding indications and long-term efficacy of the many surgical techniques for treating stress incontinence. Historically pubovaginal sling has been reserved for cases of intrinsic sphincter deficiency or prior surgical failure. Transvaginal needle and retropubic suspensions have been used mainly for sphincteric incontinence unassociated with intrinsic sphincter deficiency. We report the long-term results of pubovaginal sling for all types of stress incontinence. MATERIALS AND METHODS: A total of 251 consecutive women with all types of stress incontinence who underwent pubovaginal fascial sling by a single surgeon were retrospectively and prospectively reviewed. Patients were evaluated preoperatively with history, physical examination, standardized symptom questionnaire, voiding diary, pad test, uroflow, post-void residual urine, video urodynamics and cystoscopy. Postoperatively women with at least 1-year followup were assessed by an independent third party (J. R.) who had no prior knowledge of them, and who recorded the parameters of the questionnaire, examination with a full bladder, voiding diary, pad test, uroflow and post-void residual urine. RESULTS: Overall stress incontinence was cured or improved in 92% of the patients with at least 1-year followup (median 3.1 years, range 1 to 15). The majority of patients with postoperative incontinence had de novo (3%) or persistent (23%) urge incontinence. Permanent urinary retention developed in 4 patients (2%). CONCLUSIONS: Fascial pubovaginal sling is an effective treatment for all types of stress incontinence with acceptable long-term efficacy.     

Surgical experience with intracardiac myxomas: long-term follow-up

BACKGROUND: Myxomas are the most common benign intracardiac tumors. This report summarizes our 20-year experience with these tumors. METHODS: Sixty-six patients (25 male) with a median age of 39 years (range, 6 to 70 years) underwent surgical excision of primary or recurrent intracardiac myxomas during the years 1976 to 1996. Symptom duration ranged from 2 to 8 months. There were 55 left atrial myxomas, 10 right atrial myxomas, and 1 biatrial myxoma. Three of the patients were in one family. The surgical approach comprised complete wide excision. RESULTS: There were two early deaths. Late follow-up is 89% (57/64) complete. There was one late death, which was not due to a cardiac cause. Echocardiography at a mean follow-up of 66.9 months (range, 7 to 241 months) showed no recurrence of sporadic myxomas. However, 2 of the 3 patients with familial myxomas had recurrence. CONCLUSIONS: Surgical excision of atrial myxoma gives excellent short-term and long-term results leading to eventual cure of nonfamilial myxomas. However, familial myxomas retain a strong tendency to recur even 20 years after excision.     

Congenital epispadias with urinary incontinence: long-term results of reconstructive therapy

The author investigated the long-term results after reconstruction operations in epispadias with total urinary incontinence in 16 pediatric patients-4 girls and 12 boys. The patients were operated in 1961-1981 at the Department of pediatric surgery of the University Hospital in Hradec Králové. The operations were made most frequently between the age of 3 and 4 years. Straightening of the penis was achieved by exstirpation of the dorsal chorda and by V-Y plasty. To lengthen the penis it proved useful to separate the greater portion of the crura from the bony rami. To achieve functional continence plastic operations were made of the posterior urethra and of the bladder neck in patients of both sexes. The Young-Dees procedure proved best. The overall continence rate was achieved in 70% of operated boys and in 60% of girls. The functional failure of reconstruction was treated by secondary diversion in 2 cases, in one by ureterosigmoideostomy and in one by ileal conduit. The associated VUR reflux was corrected by Politano-Leadbetter's UCN or by the Cohen procedure. From the social aspect the patients are well adapted, they completed their training for a job. Of 12 patients where an inquiry for further information was made, with the exception of one patient, all are active in their sexual life. Seven patients are married, five men fathered 7 children and two female patients were delivered of three healthy children.     

Pancreatic duct patency after pancreaticogastrostomy: long-term follow-up study

BACKGROUND/AIMS: To clarify whether the pancreatic duct remains patent during long-term follow-up of patients after pancreaticogastrostomy. In a previous study of pancreaticogastrostomy with post-operative follow up for 3 years after surgery, we found that the orifice of the pancreatic duct was difficult to detect in some patients because of swelling of the gastric mucosa. Previous studies have not examined pancreatic duct patency during long-term follow-up. METHODOLOGY: Between July 1985 and August 1989, 20 patients underwent a pylorus-preserving pancreaticoduodenectomy with reconstruction by pancreaticogastrostomy. Five of these patients were followed up post-operatively for more than 9 years to determine the patency of the pancreatic duct. All pancreatic anastomoses were performed by the telescopic method. RESULTS: All 5 patients were female, with a mean age of 65.4 years (range: 54-75). Median post-operative follow-up was 10.8 years (range: 9-12). The indications for surgery were carcinoma of the ampulla of Vater in 4 patients and chronic pancreatitis in 1 patient. Pancreatic duct patency was confirmed in 4 patients by gastroscopy and pancreatography. However, the anastomotic orifice could not be detected in the remaining patient because of complete coverage by the gastric mucosa. In this patient, pancreatic exocrine and endocrine function deteriorated with dilation of the distal pancreatic duct. The patient underwent a second operation involving dissociation of the pancreatico-gastric anastomosis and resection of about 1 cm of the fibrous, proximal portion of the pancreas. Reconstruction was performed with a Roux-en-Y pancreaticojejunostomy and a mucosa-to-mucosa anastomosis. CONCLUSIONS: Although pancreaticogastrostomy has been applied as a safe and straightforward method for reconstruction after pancreaticoduodenectomy, anastomotic stenosis is a potential late complication of this approach.
