Intravesical migration of an intrauterine contraceptive device complicated by bladder stone: a report of six cases.

Intrauterine contraceptive device is the most popular method of reversible contraception in developing countries due to its efficiency and low cost. However, this device is often inserted by paramedics of variable skills, and follow-up evaluations are irregular or absent which can be the source of major complications. The authors report six cases of intravesical migration of intrauterine contraceptive devices complicated by bladder stones. All the six cases were managed endoscopically with excellent outcome. The authors demonstrate that this major complication can be managed endoscopically with decreased morbidity for the patient.

Intraperitoneal pocket for left ventricular assist device placement.

BACKGROUND: Implantation of the HeartMate Implanted Pneumatic or Vented Electric Ventricular Assist Device requires that the pump be implanted either in the peritoneal cavity or in the abdominal wall. Both sites have been problematic. METHODS: We describe a new technique in which an intraperitoneal pocket is created, using Gore-Tex Dual Mesh Plus Biomaterial with Holes, to contain the ventricular assist device. This shields the ventricular assist device from the peritoneal contents and avoids abdominal wall dissection. Thirty consecutive patients who underwent implantation using this technique were compared with 16 patients who underwent implantation before this technique was in use. RESULTS: Thirty consecutive patients underwent implantation, and 2 of those patients underwent re-implantation because of device failure (16/30 HeartMate Implanted Pneumatic, 14/30 HeartMate Vented Electric, and 2/14 HeartMate Vented Electric replaced with the HeartMate Implanted Pneumatic). Twenty-five patients have undergone explantation. Pocket infections in patients who have had implanted devices for >1 month decreased from 4 of 13 before the pockets were used to 1 of 25 with the intraperitoneal pockets (Fisher's exact test p = 0.038). Two hernia repairs were required after explantation when the biomaterial pocket was used. A decrease in return to surgery for bleeding was noted after the pocket was used (7/16 without the pocket and 3/32 with the pocket; Fisher's exact test, p = 0.010). CONCLUSIONS: Bleeding complications and pocket infections decreased in this early experience. Further study is necessary to confirm the apparent decrease in complication rate by using this new technique in this small cohort of patients.

Intravesical migration of levonorgestrel-releasing intrauterine system (LNG-IUS) with calculus formation.

The intrauterine contraceptive device (IUD) has been in use for many years as an effective means of birth control. Migration of the device from the uterus to the pelvic cavity is not uncommon and has been reported previously, however intravesical migration and secondary calculus formation is relatively rare. We report a 28-year-old woman in whom an intrauterine contraceptive device (LNG-IUS) migrated from the uterus to the bladder and resulted in stone formation. This case shows that the newer hormone releasing IUDs may also cause bladder perforation.

Tongue to palate contact during speech in subjects with and without a tongue thrust.

The aims of this study were to determine the location and movements of the tongue on the palate during pronunciation of Persian consonants and selected words in subjects with and without a tongue thrust (TT). Ten patients with a TT and 10 control subjects, 9-13 years of age, matched for age, gender, ethnicity, type and severity of malocclusion, with no history of orthodontic treatment, surgery, or systemic disease were selected. Maxillary alginate impressions were taken to construct upper removable appliances with 12 electrodes. Fine wires connected the electrodes to a specially designed electropalatovision (EPU) device. The removable appliance was inserted in the upper arch and then the Persian consonants and some selected words were pronounced by both groups. An electromechanical marker was included on each electrode which showed the tongue movements on the palate. Tongue movements, the quantity of the tongue contacts, and the location of the tongue were compared using t- and Chi-square tests. In the TT group, the tongue had more contact with the palate on six electrodes (P < 0.001). When pronouncing the consonants, the tongue made contact anteriorly on the palate in the TT group. The quantity of tongue contacts with the palate was similar in both groups. During pronunciation of selected words, the contact points of the tongue to the palate were similar in both groups.

Medicolegal aspects of an unusual uterine perforation with multiload-Cu 375R.

Perforation of the uterus is one of the most serious complications associated with insertion of intrauterine contraceptive devices (IUD). According to recent studies, this lesion occurs in 0.87 per 1000 cases, but statistics generally fluctuate between 0.05 and 13 per 1000 insertions. "Primary" perforations occur at the time of IUD insertion, and "secondary," or delayed, perforations are usually assumed to be caused by reactive uterine contractions. We report an unusual case of uterine perforation, which occurred 9 days after the insertion of a Multiload-Cu 375 IUD. The criteria for differential diagnosis between primary and secondary complications are discussed, particularly from the perspective of medical malpractice cases.

An approach to LVAD explantation during heart transplantation.

Reoperations during ventricular assist device (VAD) explantation and subsequent heart transplantation are difficult procedures because of dense adhesions, obliterated planes of dissection, and proximity of the right ventricle to the sternum. We present our approach for left VAD explantation to minimize potential complications that may occur during this procedure.

Computer-assisted generation of all-ceramic crowns and fixed partial dentures.

The successful application of the concept of computer-assisted manufacturing in restorative dentistry requires that computer-assisted design (CAD) and computer-assisted machining (CAM) not only meet but actually exceed currently accepted standards for the material and clinical quality of dental restorations. In addition, the continued development of systems for polyvalent processing of disparate materials and objects must be assured. With these critical requirements in mind, the Precident system is a clinically proven and competitive system. The resolving power of the CCD chip is much improved compared to conventional cameras or charge-coupled devices. The scanner is able to scan entire casts in a fully automated process. In principle, this facilitates the production of frameworks for fixed prosthetic devices (FPD) of any size. It is also possible to create at least partial frameworks for removable prosthetic devices (RPD). A factor of great clinical and economic importance is the polyvalence of the process in materials processing: the numeric control (NC) machine can be programmed for metal alloys and ceramic materials as well as fiber-reinforced resins. At Aeskulap Klinik, the Precident System is routinely used for producing all single crowns and FPDs with up to four units. CAD/CAM all-ceramic crowns and FPDs currently cost about the same as metallo-ceramic or conventional all-ceramic restorations.

Effect of a gonadotropin-releasing hormone agonist on follicle recruitment and pregnancy rate in cattle.

Two experiments were conducted to determine whether a GnRH agonist eliminated a potentially persistent first-wave dominant follicle (PDF) and recruited a new dominant follicle with improved fertility upon ovulation. In Exp. 1, five nonlactating Holstein cows were treated on d 7 (d 0 = estrus) with a norgestomet implant and PGF2 alpha (25 mg); a GnRH agonist was injected on d 9. On d 16, the norgestomet implant was removed and PGF2 alpha was injected. The corpus luteum (CL) regressed (5/5 cows), and plasma progesterone (P4) decreased (P < .01) from d 7 (P4 = 10.4 +/- .3) to 9 (P4 = 1.0 +/- .3 ng/mL). The GnRH agonist induced ovulation of the first-wave dominant follicle. New dominant follicles emerged by d 12 +/- 1. In all cows, removal of norgestomet implants and injection of PGF2 alpha on d 16 caused regression (P < .01) of the CL induced by the GnRH agonist. The GnRH agonist-recruited dominant follicles were highly estrogenic on d 17 (estradiol = 19.6 +/- .8 pg/mL) and ovulated on d 19.8 +/- .2 (5/5). In Exp. 2, 147 heifers at a synchronized estrus were assigned disproportionally but randomly to two treatments (GnRHa, n = 94; PDF, n = 53). On d 7, a used controlled internal drug releasing (CIDR-B) device was inserted into the vagina and PGF2 alpha was injected. On d 9, heifers in GnRHa were injected with GnRH agonist. The CIDR-B devices were removed and PGF2 alpha was injected into all heifers on d 16. Within 4 d after removal of CIDR-B devices, 96.8 and 94.3% of heifers in GnRHa and PDF were detected in estrus and inseminated. Pregnancy rates were GnRHa = 60.6% > PDF = 43.4% (P < .05). In summary, fertility after ovulation of a persistent first-wave dominant follicle is reduced, whereas induction of a new dominant follicle following injection of a GnRH agonist results in greater fertility.

A New Approach to Plaque Removal: The Redha-Cut Device.

PURPOSE: To prospectively determine the safety, feasibility and efficacy of a new atherectomy device. Methods. Seventy patients with 93 symptomatic femoro-popliteal lesions underwent percutaneous atherectomy with Redha-cut, a metallic, flexible catheter. The device works on pull-back with two umbrella-like blades and enables cutting, retaining and removing of material. Quantitative analysis of the angiograms was performed. RESULTS: Obtaining of atherectomized samples was successful in all cases. The mean atherectomy time was 5 +/- 2 minutes. The stenoses were reduced from 74 +/- 2.3% before to 26 +/- 2% after atherectomy (p < 0.001). Subsequent PTA, which was performed to optimize the results, further decreased the degree of stenosis to 17% (p > 0.5). No perforations, acute closure or early re-thrombosis occurred. Cumulative patency rates according to the findings of non-invasiveive examinations were 83% at 6 months and 66% at 12 months. Conclusions. The Redha-cut device is a simple, safe and efficacious tool for biopsy sampling and atherectomy. Further studies randomizing patients either to balloon or atherectomy are planned to compare this technique with others in regard to long-term patency.

Clinical applications of lasers during removable prosthetic reconstruction.

The successful construction of removable full and partial dentures depends mainly on the preoperative evaluation of the supporting hard and soft tissue structures and their proper preparation. Stability, retention, function, and esthetics of removable prostheses may be enhanced by proper laser manipulation of the soft tissues and underlying osseous structure. Compared with conventional techniques, laser treatment has many advantages. More predictable postoperative healing results and shortened treatment time may be achieved when lasers are integrated into the treatment plan for construction of removable prosthetic devices.
