Long term use of inert intrauterine contraceptive devices in 94 women in Israel.

A 22 year retrospective survey was undertaken in an Israeli family practice to determine how long inert (plastic only, unmedicated) intrauterine contraceptive devices could be safely left in place. Ninety four women were identified who had used 100 inert intrauterine contraceptive devices continuously for between five and 19 years. Fifty nine women complained of pain, increased uterine bleeding or increased vaginal discharge, but these were the reasons for removal of the device in only 32 women. There was only one case of pelvic inflammatory disease but this was treated without removal of the intrauterine contraceptive device. Of 14 women who requested to have their device removed after between five and nine years without having had any side effects, 11 women conceived within nine months. The results of the study indicate that inert intrauterine contraceptive devices can be safely left in place until the menopause. As it will take many years before the new type of copper devices can be shown to be as safe for long term use, it seems an appropriate time to reintroduce inert intrauterine contraceptive devices for women.

Immediate autogenous cartilage grafts in rhinoplasty after alloplastic implant rejection.

BACKGROUND: It is accepted in rhinoplasty that complications are more common with alloplastic implants than with autografts. There is little guidance in the literature on how to deal with the cosmetic and/or functional problems that follow alloplastic implant rejection. The conventional advice has been to remove the allograft and not place any graft at the same time. The present article presents our experience treating allograft rejection and immediately repairing any structural defect with autografts. OBJECTIVE: To demonstrate that immediate nasal reconstruction using autogenous cartilage is a good technique when an alloplastic material has to be removed because of rejection, inflammation, or infection. DESIGN: A retrospective analysis of outcome for a case series. METHODS: A retrospective review of the management of 8 patients who presented to 2 tertiary referral centers with alloplastic implant rejection following rhinoplasty. In 7 cases, the alloplastic implant had to be removed because it had migrated and caused a foreign body reaction; in 1 case, the implant had caused a bacterial infection. RESULTS: In all 8 cases, the nasal deformity that followed the removal of the allograft was so marked that the nose was immediately reconstructed with autogenous cartilage. The patients all made a good recovery after immediate reconstruction, although skin changes associated with the alloplastic implant remained after a mean follow-up of 3 years 3 months. CONCLUSION: The use of autogenous cartilage is a good option for nasal augmentation immediately after the removal of an alloplastic implant.

Removal of urinary catheter on postoperative day 3 or 4 after radical retropubic prostatectomy.

OBJECTIVES: To determine the feasibility and safety of removing the urinary catheter on postoperative day (POD) 3 or 4 after radical retropubic prostatectomy (RRP). METHODS: Between January 2001 and August 2001, gravity cystography was performed on POD 3 or 4 after RRP by a single surgeon (H.L.) on 151 men. The urinary catheter was removed on POD 3 or 4 providing no extravasation was evident on cystography. Urinary catheters were replaced over a guidewire placed into the bladder under flexible cystoscopic guidance in cases of acute urinary retention (AUR). Continence was assessed at 3 months after RRP. RESULTS: Of the 151 cystograms performed on POD 3 or 4, 116 (76.8%) revealed no evidence of extravasation. The indwelling catheters were removed in 114 of these cases (98.3%). Twenty-two (19.3%) of the 114 men whose catheters were removed on POD 3 or 4 developed AUR within 48 hours of catheter removal, requiring catheter replacement. Two of these patients required repeated surgery secondary to complications related to AUR. At 3 months after RRP, 75% of the men whose catheters were removed on POD 3 or 4 required no pads or a single pad during a 24-hour interval, and 77.6% reported none or slight bother from incontinence. Of the 37 men whose catheters were removed on POD 7 or later, 1 patient (2.7%) developed AUR, and the catheter was replaced without complications. At 3 months after RRP, 65.7% of men whose catheters were removed on POD 7 or later required no pads or a single pad during a 24-hour interval, and 71.4% reported none or slight bother from incontinence. The incidence of anastomotic stricture in men whose catheters were removed on POD 3 or 4 and POD 7 or later was 12.1% and 22.6%, respectively. CONCLUSIONS: Most men will have a watertight anastomosis on POD 3 or 4 after RRP. Early catheter removal does not have a negative impact on continence or the rate of anastomotic strictures. Because of the high incidence of AUR, requiring replacement of the urinary catheter, and the potential for disruption of the anastomosis or bladder neck reconstruction, we currently recommend delaying catheter removal until POD 7 or later.

Nonsurgical retreatment.

With all the potential for endodontic success, the fact remains clinicians are confronted with posttreatment endodontic disease. When the elected treatment plan is endodontic nonsurgical retreatment, then the goal is to access the pulp chamber and remove materials from the root canal space and if present, address deficiencies or repair defects that are pathologic or iatrogenic in origin. This article provides a literature review with clinical recommendations for one important group of retreatment issues: the removal of posts and broken instruments.

Removal of vena caval filter at 224 days.

Patients at risk of pulmonary embolism usually receive anticoagulants, which are contraindicated in trauma victims. A woman with extensive deep venous thrombosis after a vehicle accident had a nitinol Recovery Filter inserted prophylactically. After her recovery, she requested filter removal because of her intention to become pregnant. The filter was removed percutaneously without difficulty 224 days after implantation.

Acute appendicitis due to appendiceal obstruction from a migrated biliary stent.

Endoscopic plastic biliary stenting is a common procedure in the management of benign biliary pathology. Complications from biliary stenting are rare, with stent occlusion being the most common. Another late complication of long-term biliary stenting is stent migration, which occasionally can result in bowel perforation and obstruction. We report an extremely unusual complication of acute appendicitis due to appendiceal orifice obstruction from a migrated biliary stent. The condition was suspected from the history in association with the radiological findings and was successfully treated nonoperatively with endoscopic stent removal.

Monorail snare technique for the recovery of stretched platinum coils: technical case report.

OBJECTIVE AND IMPORTANCE: Coil stretching represents a potentially hazardous technical complication not infrequently encountered during the embolization of cerebral aneurysms. Often, the stretched coil cannot be advanced into the aneurysm or withdrawn intact. The operator is then forced to attempt to retract the damaged coil, which may result in coil breakage, leaving behind a significant length of potentially thrombogenic stretched coil material within the parent vessel. To overcome this problem, we devised a technique to snare the distal, unstretched, intact portion of the platinum coil by use of the indwelling microcatheter and stretched portion of the coil as a monorail guide. CLINICAL PRESENTATION: We have used this technique successfully in four patients to snare coils stretched during cerebral aneurysm embolization. Three of these patients were undergoing Neuroform (Boston Scientific/Target, Fremont, CA) stent-supported coil embolization of unruptured aneurysms. In all cases, the snare was advanced easily to the targeted site for coil engagement by use of the microcatheter as a monorail guide. Once the intact distal segment of the coil was ensnared, coil removal was uneventful, with no disturbance of the remainder of the indwelling coil pack or Neuroform stent. TECHNIQUE: A 2-mm Amplatz Goose Neck microsnare (Microvena Corp., White Bear Lake, MN) was placed through a Prowler-14 microcatheter (Cordis Corp., Miami, FL). The hub of the indwelling SL-10 microcatheter (Boston Scientific, Natick, MA) was then cut away with a scalpel, leaving the coil pusher wire intact, and removed. The open 2-mm snare was then advanced over the outside of the coil pusher wire and microcatheter. The snare and Prowler-14 microcatheter were then advanced into the guiding catheter (6- or 7-French) as a unit over the indwelling SL-10 microcatheter. By use of the SL-10 microcatheter and coil as a "monorail" guide, the snare was advanced over and beyond the microcatheter and the stretched portion of the coil until the snare was in position to engage the distal unstretched coil. At this point, the snare was then closed around the intact portion of the coil, and the microcatheters, snare, and coil were removed as a unit. CONCLUSION: The monorail snare technique represents a fast, safe, and easy method by which a stretched coil can be removed.

Buried bumper syndrome with a fatal outcome, presenting early as gastrointestinal bleeding after percutaneous endoscopic gastrostomy placement.

Percutaneous Endoscopic Gastrostomy (PEG) has gained wide acceptance among patients who require prolonged tube-feeding support. A rather unusual complication of PEG placement is migration of the internal bumper through or into the abdominal wall. This was first described in 1988 and is called the buried bumper syndrome (BBS). The syndrome is a late complication of PEG tube placement. The manifestations of the syndrome must be recognised and the patient referred for emergency endoscopy and removal of the bumper. Failure to recognise this syndrome may result in serious complications including gastrointestinal bleeding, perforation of the stomach, peritonitis and death. We describe a case where a patient developed the buried bumper syndrome quite early after PEG placement. The syndrome manifested with gastrointestinal bleeding. Although we removed the buried bumper endoscopically, and placed another PEG tube, the patient developed peritonitis and died 16 hours after the removal of the migrated bumper.

Initial clinical experience with the pacemaker-cardioverter-defibrillator.

The implantation of a new multiprogrammable pacemaker-cardioverter-defibrillator is reported in four patients suffering from drug-refractory ventricular tachycardia or fibrillation. The generator (PCD 7215; Medtronic Inc) was interfaced to the epicardium by three countershock patch electrodes and one ventricular myocardial screw-in lead for sensing/pacing. The device employs separate rate detection criteria for ventricular tachycardia and ventricular fibrillation with automatic delivery of up to four therapies per episode. Therapeutic options include: antitachycardia burst or autodecremental pacing, synchronized cardioversion, defibrillation and ventricular demand pacing at 30 to 90 beats/min. Four men and one woman (ages 29 to 75 years) underwent intraoperative implant evaluation, and the device was implanted in the four men. Over a follow-up of 1.5 to 23 months, 161 spontaneous episodes of ventricular tachycardia and nine episodes meeting ventricular fibrillation criteria (cycle length less than 280 to 290 ms) were detected and treated by the device. Ramp pacing was initially employed to terminate 140 ventricular tachycardia episodes and was successful 88.5% of the time while 10 (7.2%) required low energy epicardial cardioversion (4 to 10 J). Six (4.3%) episodes terminated spontaneously prior to therapy delivery. All nine spontaneous episodes of ventricular fibrillation were defibrillated using 10 to 15 J. Two patients continue to do well with the device functioning reliably. The device was removed at the time of heart transplant in one patient, while another patient died suddenly from drug overdose. No other complications, device malfunctions or inappropriate therapy delivery have been observed. These early results demonstrate the potential usefulness of a programmable device which provides graded therapy for ventricular tachycardia with added defibrillation and bradycardia pacing capability.

Nitrous oxide scavenging in dental surgery. I. A comparison of the efficiency of different scavenging devices.

Chronic exposure of dental personnel to trace concentrations of nitrous oxide has been reported to constitute a health hazard. During the dental treatment under nitrous oxide-oxygen sedation dentists are frequently exposed to as much as 1000 ppm of nitrous oxide. Nitrous oxide-oxygen sedation equipment with scavenging devices for removal of expired and excess gases is available. The aim of this study was to determine the efficiency of different scavenging devices by means of a standardised experimental model and thereby study occupational nitrous oxide exposure in dental surgery. Seven commercially available breathing systems were studied. The experimental model of measuring occupational nitrous oxide exposure during a 25-minute standardised dental treatment showed high reproducibility and might be useful for determining whether or not a system has a reasonable chance of meeting the requirements set by different national boards of occupational safety and health. The scavenging efficiency of the different systems tested varied. According to this method of evaluation, five out of seven systems might have good possibilities of meeting Swedish standards of occupational exposure (nitrous oxide limit value 100 ppm).

One-year results with the Fincoid IUD--a Hungarian experience with the short model.

This study presents the one-year experience with a new copper-releasing intrauterine contraceptive device, the Fincoid IUD. Between November 1984 and August 1985, 650 Fincoid devices were inserted in parous women to test the efficacy and clinical performance of the devices. After one year, 16 pregnancies had occurred (2.8 net cumulative rate); 26 devices had been partially or totally expelled (4.4); 27 devices had been removed for bleeding and/or pain (4.7); and 16 devices had been removed for other medical reasons (2.8). The continuation rate at the end of the first year was 84.3, indicating a good clinical performance.
