A general dentist's viewpoint of two new endodontic techniques.

Over 3 years ago, two new endodontic techniques were developed. The first was a straightforward, comprehensive approach for root canal instrumentation. The second was a simple and predictable obturation system. The combination of these systems lead to impressive results that were easily attained. The instrumentation method uses existing armamentarium, allowing nearly any canal to be shaped to ideal form to precisely match a tapered gutta percha point. The root canal sealer technique incorporates controlled placement of a modified epoxy-resin cement that allows for a thoroughly sealed, single-cone root canal fill. The results rival other available systems. This article presents a stepwise guide to achieve stress-free, successful case results that general dentists and endodontists desire.

Laparoscopic ureteroureterostomy: a prospective follow-up of 9 patients.

Objective: To report the technique and long-term outcome of laparoscopic ureteroureterostomy of injured ureter.Design: A prospective follow-up study.Materials and Methods: Follow-up of nine patients, aged 30-43 years, who acquired intentional ureteral injury during operative laparoscopy for treatment of endometriosis. They were treated between September 1991 and September 1997 by ureteral transection or resection with primary laparoscopic repair by ureteroureterostomy (8 procedures) and ureteroneocystostomy (2 procedures).Results: All operations were successfully completed by operative laparoscopy without need to convert to laparotomy. Estimated blood loss related to the ureteral portion of the procedure was less than 100 mL. Duration of follow-up was between 2 months and 6 years. Follow-up intravenous pyelogram revealed complete healing in seven patients. One patient had mild ureteral stricture, which resolved with transvesical ureteral dilatation, and she is doing well 4 years postoperatively. Another patient with severe endometriosis had recurrent ureteral stricture due to fibrosis distal to the anastomosis site. She underwent laparoscopic ureteroneocystostomy psoas hitch and is doing well 3 months postoperatively.Conclusions: This is the first series of laparoscopic ureter reanastomosis reported to date. The outcome was excellent with low postoperative morbidity typically associated with laparoscopy.

Postpartum psychiatric illness: the role of the pediatrician.

PPD occurs in 10% to 20% of postpartum women. Maternal depression can affect a child's development significantly. Pediatricians can screen for maternal psychiatric illness with little effort; of all the health care professionals, they may be in the best position to do so. Pediatricians can help affected mothers obtain appropriate treatment and help mobilize social resources. This simple process can minimize morbidity to pediatric patients.

The silicone columellar strut.

The placement of a silicone columellar strut serves to correct columellar retraction, to improve the nasolabial angle, and to increase tip projection by elevating the medical crura of the lower lateral cartilages. The potential complications of extrusion, infection, and migration are minimal if the implant is placed in a separate watertight compartment with a tension-free closure and no impingement of the nasal dome.

The Incidence of Endometriosis in Posthysterectomy Women

One hundred consecutive patients, age 24-62, status post total hysterectomy with and without bilateral oophorectomy (BSO), presented with chronic pelvic pain. All underwent laparoscopy. Of those who did not have BSO, 30 had definite endometriosis found at laparoscopy and five had questionable endometriosis. Of the 30 patients found to have definite endometriosis, 24 had a positive history of endometriosis, five had a negative history and one had a questionable history. Sixty-four underwent total hysterectomy with BSO. Of these 64, definite endometriosis was found in 22 at laparoscopy, questionable endometriosis was noted in 3, and findings for 39 were negative. Of the 22 women with positive endometriosis, 19 had a positive history of endometriosis, 2 had a negative history and 1 had a questionable history. Of these 22 patients, 13 were on estrogen replacement therapy, 2 were on estrogen and progesterone, 2 were on testosterone estradiol pellets, 2 were on GnRH analogs, 1 was on danazol and 2 received no medication. In this group, the time between hysterectomy and our laparoscopy was eight months to 15 years. Twenty-four of the 100 patients had a positive history of endometriosis with negative findings at laparoscopy. Our findings support the view that endometriosis will be found at laparoscopy in a significant number of women with chronic pelvic pain status post hysterectomy with or without BSO, especially if the woman has a positive history of endometriosis.

Laparoscopic Management of Genitourinary Endometriosis

We treated 17 patients with severe endometriosis involving the genitourinary tract. Eight women presented with persistent right or left flank pain, two presented with known ureteral obstruction, and five presented with urinary frequency and burning, and/or hematuria with their periods. Presented are the results of laparoscopic management in these patients. We performed segmental bladder resection in six patients and ureteral resection and reanastomosis in two. Nine additional patients underwent partial resection of the ureteral wall for complete removal of endometrial implants. The ureter was repaired with 4-0 PDS in seven patients and a stent was left in place for 4 to 6 weeks. Two required only a stent due to the small size of the ureterotomy. The postoperative course of these patients was uneventful. Following ureteral repair/reanastomosis, all women underwent an intravenous pyelogram at follow-up, and normal bilateral excretion was demonstrated. Cystoscopy revealed no abnormal findings in five patients who had undergone partial bladder resection. All patients reported significant pain relief or complete resolution of symptoms. Operative laparoscopy can be safely used to achieve relief from severe symptomatic endometriosis of the genitourinary tract.

Complications of 361 Laparoscopic Hysterectomies

We evaluated the results and complications of 361 hysterectomies performed at operative laparoscopy to treat a variety of benign gynecologic conditions. The hysterectomies were classified according to the number of steps performed endoscopically. There were no conversions to laparotomy for the hysterectomy, although one required laparotomy for rectosigmoid resection and anastomosis due to severe stricture of the rectosigmoid colon. There were no cases of mortality during the hospitalization nor during 42 postoperative days. The overall complication rate was 10.23 per 100 women. Intraoperative complications included three inferior epigastric vessel injuries, two hemorrhages requiring blood transfusion, one small bowel injury and one bladder injury. The overall complication rate in this series is lower than that reported for abdominal or vaginal hysterectomy. Laparoscopically assisted hysterectomy allows the surgeon to directly visualize uterine artery pedicles, to clearly delineate ureteral paths, to accomplish immediate and precise hemostasis, to use hydrostatic lavage and irrigation to continuously disperse microclots and tissue debris, and to operate with accuracy. While this procedure seems to offer several advantages such as reduced devitalized tissue, near elimination of the potential for suture reaction, and diminished inflammatory responses during the healing phase, complications can be encountered.

Successful replantation of both legs in a child--5-year followup: case report.

Replantation of lower extremities is an infrequent procedure, and is rarely indicated, due to the usual severity of the primary injury plus the possibility of good prosthetic substitution. We report a case of successful replantation of both legs in an 8-year-old boy (despite Aspergillus flavus septicemia) with followup of 5 years. This case suggests that leg replantation should be considered in young patients. This appears to be the second reported case of successful replantation of both legs.

The effects of prolonged stimulus repetition with repeated switching of target status on the orienting response in schizophrenia and depression.

Schizophrenic patients are frequently orienting nonresponders to innocuous stimuli, become responsive to significant target signals, and become hyporesponsive again on prolonged repetition. We wish to a) determine whether schizophrenic patients can display orienting response (OR) flexibility, responding to newly designated targets and ceasing to respond to newly designated nontargets; b) determine whether renewed hyporesponding can be averted with reminders of target relevance and repeated introduction of new targets; and c) compare schizophrenics with depressives and normal controls. Fifty schizophrenics (14 drug free), 50 depressives (20 drug free), and 50 normal controls receive four trial blocks involving the same sequence of 16 1000- or 2000-Hz tones delivered to either the right or left ear. A subsample of each group (N = 14) receives all blocks as a simple habituation series; others (N = 36) have to press a pedal for designated target signals (left ear or right ear, 1000 Hz or 2000 Hz), ignoring all nontarget tones. On each trial block, a new target signal is defined, and previous targets are discarded. Skin conductance and finger pulse amplitude analyses are presented. Both patient groups show enhanced ORs to newly relevant targets and ceased ORs to newly irrelevant former targets as well as normals. Both show OR decline with target repetition despite reminders and new targets.

State health manpower planning in the 1980s.

Despite the importance of the state role in health manpower, past studies have documented fragmentation of effort, isolation of health manpower planning from other health policy channels and a relatively low level of interest in manpower issues on the part of state and local health planners. In evaluating the current capabilities of state level agencies to undertake increased responsibility for health manpower planning, this paper: 1) assesses the level of interest and involvement of state health planning and development agencies (SHPDAs) in health manpower planning; 2 (examines health manpower policy issues in states as evidenced in state health plans; and 3) describes the policy environment in which state health manpower planning is currently conducted.

Selected epidemiological features of herpes genitalis in Israel based on laboratory data.

The incidence in Israel of genital infection with herpes simplex virus (HSV) has been increasing steadily over the last two decades. During the years 1973-91, 1,508 patients had an HSV infection confirmed by viral culturing. The yearly incidence of new cases rose from sporadic cases in the seventies to 32.4 cases per 1,000 patients in 1990. The age distribution pattern did not change since 1980 and showed a peak incidence in subjects aged 20-40 years. The increase of HSV type 2 (HSV-2) infection rate in the Israeli population, as judged from specific geometric mean titers (GMT), rose from 15.25 in 1970 to 89.3 in 1991, while the GMT for HSV type 1 (HSV-1) did not increase significantly. The incidence of HSV-2 positive subjects (HSV-2/HSV-1 antibody ratio > or = 1) was low in the Jewish Israeli population, compared to other demographic areas. The predominant type of genital infection was HSV-2, although 21% of genital isolates were HSV-1.
