Unrelated donor bone marrow transplantation without T cell depletion using a chemotherapy only condition regimen. Low incidence of failed engraftment and severe acute GVHD

STUDY OBJECTIVE: To assess the efficacy and safety of operative resectoscopy, partial endomyometrial resection, and endometrial ablation in the evaluation and treatment of abnormal uterine bleeding. DESIGN: Retrospective analysis of 305 consecutive cases of endometrial ablation and partial endomyometrial resection. SETTING: Midwestern urban obstetric and gynecology group practice and teaching hospitals. PATIENTS: Three hundred five women (age 30-72 yrs) with abnormal uterine bleeding. Interventions. Partial endomyometrial resection and endometrial ablation. MEASUREMENTS AND MAIN RESULTS: Of the 301 patients who completed surgery and follow-up, 283 (97%) reported improvements in amenorrhea (55%), hypomenorrhea (41%), and eumenorrhea (1%). Ten (3%) failed to report improvement. In 24 (7.9%) women, hysterectomy was performed for various reasons after endometrial ablation, including recurrent bleeding in 4. Four uterine perforations occurred, infection was suspected in one patient, and loss of Laminaria occurred in another; all patients, however, were observed appropriately and discharged the same day of surgery. CONCLUSIONS: Partial endomyometrial resection and endometrial ablation is a safe and effective treatment of abnormal uterine bleeding, and may be an alternative to hysterectomy in selected patients.     

Conversion ratio of tryptophan to niacin in rats fed a vitamin B1-free diet

Patients with persistent uterine bleeding that is unresponsive to conservative therapy may opt for endometrial ablation over total hysterectomy because of concerns over subsequent sexual dysfunction or other nonclinical issues. Twelve such women with healthy cervices who failed endometrial ablation, and eight candidates for ablation were offered subtotal vaginal hysterectomy as a definitive primary surgical intervention instead of endometrial ablation. Our experience suggests the safety and utility of subtotal vaginal hysterectomy in properly selected patients. Randomized, comparative studies of this technique as an alternative to hysteroscopic ablation or resection may be warranted.     

In cell amplification

130 total hysteroscopic resections of the endometrium (RE) were performed at the Department of Gynecology and Obstetrics of the Deutschlandsberg Hospital from August 1, 1992 to May 31, 1997. 115 patients (88.5%) suffered from distinctive therapy-resistant uterine bleeding in terms of hypermenorrhea and menorrhagia, frequently combined with poly- and dysmenorrhea. 15 (11.5%) women who had previously been operated for breast cancer developed--during continuous treatment with tamoxifen--endometrial hyperplasia or polyps on which RE was performed after a hysteroscopic biopsy or resection had been carried out in a second setting. The operation showed that 98 out of 115 patients (85.2%) had pathologic anomalous uteri which were the organic cause of the uterine bleeding. Only 17 women (14.8%) suffered from dysfunctional uterine bleeding (12 cases) or from iatrogenically reduced coagulability (5 cases). The majority of the women (106 cases = 81.5%) were older than 40 (average 46.9 +/- 6.21 years). All RE were performed under inhalation anesthesia whereby the complete uterine cavity up to the inner orifice of the uterus was resected with the resectoscope loop. 92 out of 130 patients (70.8%) underwent a hysteroscopy or a dilatation and curettage before the RE. 77 patients (66.9%) received pretreatment with drugs to reduce the endometrium. 15 women (13.0%) underwent a laparoscopic tubal sterilization in the same setting. Finally, the results of 107 patients were analyzed excluding dropouts and patients who had undergone continuous treatment with tamoxifen and those who had an observation time of less than 6 months. After an observation period of 6-58 months, the success rate was 84.1%. For treatment of relapses 7 second resections were performed, whereby in 1 patient with a further uterine bleeding the uterus had to be extirpated. Nine of the 10 remaining patients had a hysterectomy, 1 patient refused any further treatment. The total hysterectomy rate was 12.2%. Basically, RE is absolutely practicable as far as the treatment of abnormal uterine bleeding is concerned, since hysterectomy can be avoided in a number of cases. Satisfactory long-term results, however, can only be achieved if indication and operation technique are of high quality. A problem which has not yet been solved is the indication and treatment of proliferating adenomyosis uteri interna.     

Thermoregulated radiofrequency endometrial ablation

OBJECTIVE: To test the hypothesis that treating dysfunctional uterine bleeding by automated application of electrothermal energy to the uterine cavity, with precise regional control, might yield results equivalent to those reported for hysteroscopically directed laser and electrosurgical endometrial ablations. MATERIALS AND METHODS: Patients with life style compromising menorrhagia, referred to six gynecologic surgical centers for hysterectomy or endometrial ablation, were admitted to the study if they had normal cervical cytology, a benign endometrial biopsy, no defined cause for their bleeding, and consented to participate in the evaluation of a newly developed Vesta DUB Treatment System. The device consists of a silicone-inflatable electrode carrier to be inserted into the uterine cavity and a controller to monitor and distribute current from a matched electrosurgical generator. Treatment involved a 3-minute or shorter warm-up period and a 4-minute treatment phase. RESULTS: Three- to 24-month follow-up data were available for 187 patients, with a mean follow-up of 14.8 months. The amenorrhea rate was 38%. Bleeding was reduced in 95% of patients. Actuarially, 88 +/- 3% of patients should expect to be free of menorrhagia, dissatisfaction, or need for a second procedure out to 24 months. CONCLUSIONS: The unique regional feed-back control offered by this system causes thorough, evenly distributed, thermal destruction 4-5 mm into the myometrium that reduces bleeding with durability equivalent to published reports of hysteroscopic endometrial ablation.     

Chlorhexidine as a root canal medicament for treating inflammatory lesions in the periodontal space

OBJECTIVE: Abnormal uterine bleeding is a common and troublesome problem in human immunodeficiency virus (HIV)-infected women. We sought to evaluate endometrial pathology among HIV-infected women requiring hysterectomy to explore if endometritis may be common among these patients. METHODS: We performed a retrospective analysis of uterine pathology specimens obtained from HIV-infected and control patients requiring hysterectomy in two urban hospitals between 1988 and 1997 matched for age, surgical indication, and history of gonadotropin-releasing hormone (GnRH) use. Cases were evaluated for the presence of plasma cells and assigned a grade between 0 and 3. RESULTS: Indications included cervical dysplasia (4), carcinoma in situ (2), abnormal uterine bleeding (3), and adnexal mass (3). Some degree of abnormal uterine bleeding occurred in all cases. Plasma cell endometritis was twice as common in HIV-infected women compared to HIV-negative specimens (11/11 versus 11/22) (P < 0.05). Plasma cell endometritis was also of a higher grade in specimens from HIV-infected women than in controls (P = 0.001). CONCLUSION: Chronic endometritis was common and of a higher grade among HIV-infected women requiring hysterectomy in our series. Diagnosis and treatment of endometritis should be considered in HIV-infected women with uterine bleeding and/or tenderness. We speculate that antiretroviral and/or antimicrobial treatment for endometritis may effectively treat endometritis and eliminate the need for surgery in some HIV-infected women. We suggest that consideration and treatment of endometritis in HIV-1 infected women being evaluated for possible hysterectomy has the potential to reduce costs and morbidity for patients and providers who may be exposed during surgical procedures.     

Enhancement of aflatoxin B1-induced enzyme altered hepatic foci in rats by treatment with carbon tetrachloride

Hysterectomy is the second most commonly performed major operation in the United States. Approximately one in three women will have this operation, resulting in 590,000 procedures per year. The most common indications for hysterectomy are leiomyomata uteri, abnormal uterine bleeding, endometriosis, pelvic pain, and pelvic organ prolapse. Although hysterectomy is an appropriate therapeutic option for some women with these conditions, in many instances less radical alternatives may be offered. Leiomyomata may be managed expectantly if symptoms are not bothersome; for women with troubling leiomyomata symptoms, alternatives to hysterectomy include: endoscopic removal or destruction of myomas, arterial embolization, or hormonal therapy to inhibit or modify bleeding. Endometriosis and abnormal uterine bleeding of leiomyomata are both amenable to hormonal therapy. Pelvic pain is most effectively approached with a thorough evaluation (particularly for nongynecologic illness), with specific therapy directed at the cause of the pain. Pelvic organ prolapse may respond symptomatically to pelvic floor exercises, or to the use of a pessary. After alternatives to removal of the uterus are discussed, the informed woman may decide that hysterectomy is the option best suited to her. It is unusual for hysterectomy to be her only option.     

Laparoscopic-assisted vaginal hysterectomy and bilateral salpingo-oophorectomy with suturing technique

Since December 1992 we have performed laparoscopic-assisted vaginal hysterectomy (LAVH) in 50 women using strict, conventional, basic operative rules, and compared it with open abdominal hysterectomy with respect to operation time, cost, postoperative analgesia requirements, and length of hospital stay. The indications for hysterectomy were uterine myoma in 32 patients, dysfunctional bleeding in 13, and postmenopausal bleeding in 5. The mean operating time was 118 minutes. The mean blood loss was 3.2% for preoperative and postoperative hematocrit values. The complication rate was 15%. The advantages of LAVH include short hospitalization, early recovery, low blood loss, and minimal postoperative discomfort.     

Implication of VEGF and MMPs in hepatic metastasis of human colon cancer

In contrast to other types of cervical adenocarcinoma, well-differentiated papillary villoglandular adenocarcinoma of the uterine cervix is unique for its tendency to develop in young women and its excellent prognosis. Until now, no tumor recurrence has been reported in the English literature following surgical treatment that varies from conization to radical hysterectomy. We report a case of 47-year-old female who presented with postcoital bleeding and was treated by radical hysterectomy for FIGO (International Federation of Gynecologists and Obstetricians) Stage Ib cervical carcinoma, in which the preoperative cervical biopsy diagnosis was adenocarcinoma. The patient was well at follow-up nine months after surgery. A literature review including treatment implications is presented.     

Hysteroscopic resection of the endometrium: an alternative to hysterectomy?

A study carried out on 342 cases of endometrial resection, with a follow up of 3 to 36 months, has allowed us to precise: 1. The indications of this technique: patients more than 40 years, suffering of abnormal uterine bleeding. 2. The endometrial ablation was performed by electrosurgery through an operating channel of the hysteroscopic sheet (9 mm) and with a glycocol distended media (1.5%). The mean time to complete the operation was 35 +/- 10 minutes, the mean length of the hospital stay was 1 day. We had no serious complications. 3. And the rate of success (amenorrhea or hypomenorrhea) was 95% at 3 months but decreased at 90% at 36 months. The rate of secondary hysterectomy was 10%, due to the associated lesions: myoma with adenomyosis in 50% of the cases. There was some evidence of superior health related quality of life among hysterectomy patients. It's the reason why it is necessary to make a serious selection of the patients who are to be treated by this method in order to avoid complications and secondary hysterectomy.     

Doppler velocimetry of the uterine arteries after hysteroscopic rollerball endometrial ablation

The aim of this study was to document the Doppler indices [pulsatility index (PI) and resistance index (RI)] of the uterine arteries in 30 patients who underwent hysteroscopic rollerball endometrial ablation for dysfunctional uterine bleeding by transvaginal pulsed Doppler sonography, and to reveal whether treatment failures (persistent menometrorrhagia) can be predicted by the blood flow characteristics of the uterine arteries in advance. On the basis of the outcome of patients at the end of the first postoperative year, the Doppler indices of the uterine arteries were meaningful 1 year after the operation when PI (1.32 +/- 0.11; mean +/- SD) and RI (0.71 +/- 0.04) in six menometrorrhagic patients were statistically different from PI (2.19 +/- 0.28; 1.95 +/- 0.36 and 1.82 +/- 0.37) and RI (0.87 +/- 0.06; 0.82 +/- 0.06 and 0.81 +/- 0.04) in normally menstruating, amenorrhoeic and hypomenorrhoeic patients respectively (P < 0.05). On the other hand, the patients who would be menometrorrhagic one year after the operation had a thicker endometrium in the first post-operative month. These findings suggest that the angiogenetic role of the persistent endometrial islands after endometrial ablation needs at some time to be reflected as changes in the Doppler parameters of the uterine arteries.     

Treatment with a gonadotrophin releasing hormone agonist before hysterectomy for leiomyomas: results of a multicentre, randomised controlled trial

OBJECTIVES: To ascertain whether uterine shrinkage induced by a gonadotrophin releasing hormone agonist before hysterectomy for fibroids increases the possibility of a vaginal procedure. DESIGN: A multicentre, prospective, randomised, controlled study. PARTICIPANTS: One hundred and twenty-seven premenopausal women with a uterine volume of 12 to 16 gestational weeks. INTERVENTIONS: Twelve weeks of triptorelin depot treatment before hysterectomy or immediate surgery. MAIN OUTCOME MEASURES: Number of vaginal and abdominal hysterectomies, operating time, blood loss, degree of difficulty of the procedure, perioperative serum haemoglobin and haematocrit levels, hospital stay, and patients' overall satisfaction with treatment. RESULTS: After randomisation, four women withdrew from the study, leaving 60 women in the triptorelin arm and 63 in the immediate surgery arm. At baseline evaluation a vaginal hysterectomy was indicated in seven women allocated to pre-operative medical therapy (12%), and in 10 of those allocated to immediate surgery (16%). Clinical assessment after the 12-week GnRH agonist course showed that abdominal hysterectomy was no longer indicated in 25/53 women (47%) as a vaginal procedure appeared appropriate. Thus the overall rate of indication for a vaginal procedure in the pre-operative medical treatment arm was 32/60 cases (53%), with a between-group difference of 37% (95% CI, 26% to 51%; chi2(1) = 19.18, P < 0.0001; OR 6.06; 95% CI, 2.60 to 14.10). Pre- and post-operative serum haemoglobin and haematocrit levels were significantly higher in the GnRH agonist than in the immediate surgery arm. No appreciable difference was observed between the groups in the other intra- and post-operative variables, including patients' satisfaction. CONCLUSIONS: Pre-operative GnRH agonist therapy increased the rate of vaginal hysterectomy in selected women with fibroids and uterine volume of 12 to 16 gestational weeks.     

Flavone acetic acid enhances accumulation of IL-2 activated NK cells within established metastases

OBJECTIVE: In 1995, we presented our experience in hysteroscopic resection of hemorrhagic submucous fibroids in 196 patients. The objective of the present work was to analyze functional outcome three years later. PATIENTS: One hundred ninety-six patients with abnormal uterine bleeding were treated between 1987 and 1993. Equipment, techniques, characteristics of the procedures and early results were detailed in the previous article. RESULTS: With a mean follow-up of 73 months (range 50,104), results were: 13.8% of the patients were lost to follow-up; 68.4% had symptomatic improvement and failure was observed in 17.8% (subsequent hysterectomy in 12.7%). Forty-nine patients had repeat resection in this series; 61 became menopausal after surgery, and 21 were taking hormone replacement therapy with good results. CONCLUSION: Developed as an alternative to hysterectomy, operative hysteroscopy has proven to be a safe and effective procedure. This treatment modality appears to give satisfactory long-term results, with a low rate of complications.     

A new method for measuring menstrual blood loss and its use in screening women before endometrial ablation

OBJECTIVE: 1. To develop and validate a method for measuring menstrual blood loss in a routine setting, and 2. To assess the value of measuring menstrual blood loss before endometrial ablation. DESIGN: A prospective, observational study. SETTING: Four Yorkshire hospitals: The General Infirmary at Leeds, St. James's University Hospital, Leeds, St. Luke's Hospital, Bradford and The Friarage Hospital, Northallerton. PARTICIPANTS: Three hundred and seventy-two women who had been offered endometrial ablation for menorrhagia. MEASUREMENT: Sanitary material was washed with a nonionic detergent in a known volume of water. The haemoglobin in a sample of solution was measured by mixing with sodium carbonate for spectrophotometric analysis. INTERVENTIONS: The menstrual blood loss result was revealed to each women. Electrosurgical endometrial ablation was performed for those who decided to have surgery. MAIN OUTCOME MEASURES: Proportion of women with normal menstrual blood loss (< or = 80 mL) who avoided surgery. Comparison of endometrial ablation outcome in women with and without genuine menorrhagia. RESULTS: Thirty-six women (10%) with normal menstrual blood loss who declined surgery continued to avoid surgery after a mean of 27 months. Two hundred and ninety-two women were followed up for one year after endometrial ablation. Those with genuine menorrhagia (n = 122) were less likely to be dissatisfied (9% vs 18%) (OR 2.5, 95% CI 1.1-4.7) or to require hysterectomy (4% vs 7%) (OR 1.8, 95% CI 0.6-5.2) than women with normal menstrual blood loss (n = 170). CONCLUSIONS: The objective diagnosis of menorrhagia can be undertaken in a routine setting and may provide some women, who have a normal menstrual blood loss, sufficient reassurance to refrain from surgery. Women with genuine menorrhagia have a better outcome after endometrial ablation than those with normal menstrual blood loss.     

Endometrial ablation. A review of the technics and results

The authors make a careful examination of a very new surgical hysteroscopic technique, endometrial ablation, which is proposed as an alternative to hysterectomy in cases of persistent uterine bleeding not supported by endometrial atypia or adenocarcinoma. In addition to examining the indications for this type of surgery the authors also assess the state of the art of two techniques currently used: the laser technique and the method based on electroresection. The risks, benefits, collateral effects and results are evaluated for each method.     

Vaginal hysterectomy for the large uterus

OBJECTIVE: To assess the feasibility and safety of performing vaginal hysterectomy on enlarged uteri the equivalent of 14 to 20 weeks of gestation in size. DESIGN: A prospective observational study. SETTING: The Royal Free Hospital, London. PARTICIPANTS: Fourteen consecutive women undergoing vaginal hysterectomy for uterine fibroids up to 20 weeks in size. INTERVENTIONS: Vaginal hysterectomy with or without bilateral salpingo-oophorectomy or oophorectomy. MAIN OUTCOME MEASURES: Uterine size and weight, techniques used to reduce uterine size, surgical outcome, operative time, estimated operative blood loss, intra- and post-operative complications, duration of hospitalisation. RESULTS: The mean uterine size was 16.3 weeks (range 14 to 20 weeks). All hysterectomies were completed successfully by the vaginal route. The uteri weighed 380 to 1100 g, with a mean of 638.7 g. Bisection combined with myomectomy and morcellation were used in most cases to obtain reduction in uterine size, whereas coring was only utilised in two cases. The mean operating time was 84.3 min with a range of 30 to 150 min. The only complications were transient haematuria (n = 6) and superficial vaginal grazes (n = 5). One of the women required a blood transfusion. The mean post-operative hospital stay was 3.7 days (range 2 to 9 days). CONCLUSION: Enlargement of the uterus to a size equivalent to 20 weeks of gestation should no longer be considered a contraindication to vaginal hysterectomy. Many more hysterectomies should be carried out vaginally without resorting to abdominal or laparoscopic surgery.     

Spectroscopic and thermodynamic evidence for a complex denaturation mechanism of bovine beta-lactoglobulin A

PURPOSE/OBJECTIVES: To investigate the patterns of functioning and psychosocial adjustment of midlife and older women following surgery for breast cancer. Differences between those who received follow-up adjuvant therapy and those who did not also were compared. DESIGN: 2 x 3 mixed design with one between-groups factor (type of treatment) and one within-subjects factor (time). SETTING: Four midwestern hospitals. SAMPLE: 46 patients with breast cancer who are age 55 or older. METHODS: Baseline data about presurgical functional status and other variables were obtained during the first week after surgery. Follow-up data were obtained at six weeks, three months, and six months postsurgery. Data were collected via telephone interviews and mailed questionnaires. MAIN RESEARCH VARIABLES: Functional status, patient symptomatology, quality of life (QOL), demands of illness, and type of treatment (surgery only versus surgery plus adjuvant therapy). FINDINGS: No differences existed between the two treatment groups at baseline, with the exception of lower functional status reported by the surgery-only group. In the surgery-only group, functional status improved significantly from six weeks to three months postsurgery. The most frequently reported symptoms of both groups included fatigue and pain. CONCLUSIONS: These results suggest that both groups did equally well, regardless of whether they received adjuvant therapy (radiation or chemotherapy). Neither QOL nor demands of illness differed between the two groups, nor did these scores change significantly over time following surgery. IMPLICATIONS FOR NURSING PRACTICE: These findings suggest that women undergoing surgery for breast cancer, whether they receive adjuvant therapy or not, may have functional and psychosocial needs that could be effectively addressed by nursing interventions pre- and postsurgery.     

Complications after hysterectomy. A Danish population based study 1978-1983

We studied complications after hysterectomy among all women in the Danish population who had a simple hysterectomy in the period 1978-81 based on data obtained from the Danish National Hospital Registry. Among patients, with neither diagnosed cancer nor major co-surgery (n = 23,386), we identified all the complications which occurred during hospital admission from the time of surgery up to six years from that point. Within 30 days of hysterectomy 2.6% of the patients had been diagnosed in hospitals as having complications according to our definition. The corresponding figures at 90 days and two years after the operation were 3.7% and 9.4%. The most frequently observed complications were post operative wound infections and bleeding, each affecting about 2% of all operated women. Logistic regression and Cox regression were used to identify prognostic indicators of readmission with complications. The probability of readmission with complications within six years after hysterectomy was estimated at 8% among low risk patients. The most pronounced increase in risk of readmission with complication occurred among women who had been admitted to psychiatric or somatic hospitals 0-12 months before they had their uterus removed (OR in the range 1.59 to 1.83). We discuss the prevailing difficulties of comparing observational evidence from different clinical settings reported in the literature, and emphasize the importance of developing a coordinated international strategy for non-experimental assessment of medical technology.     

Hysterectomy trends in Finland in 1987-1995--a register based analysis

BACKGROUND: The study objective was to identify trends in the use of hysterectomy by nationwide register based analysis in Finland. METHODS: All women (n=89,069) undergoing hysterectomy in 1987-1995 according to the Finnish Hospital Discharge Register were the numerator. The annual denominator data were obtained from the population database of Statistics Finland. RESULTS: From 1987 to 1992 the hysterectomy rate increased by 22%, from 340 to 414 per 100,000 females, almost half of this being attributable to the changing age structure. From 1993 on, ambiguity in coding laparoscopically assisted vaginal hysterectomies prohibited detailed analyses. However, the overall trend continued at least among women 50 years and over until 1995. The age-adjusted 12% increase from 1987 to 1992 coincided with a rapid increase in operation rates in postmenopausal groups (60% or more among women aged 55 59 and 70-79 years). Among women aged 55-64 years, operations for fibroids and uterine bleeding more than doubled, suggesting an influence of increased use of estrogen replacement therapy. Among all women, operations due to bleeding disorders and genital prolapse showed the largest increase (41% and 42% respectively). Bilateral oophorectomy became more common in all age groups over 46 years. CONCLUSIONS: There was a modest increase in the overall hysterectomy rate. However, the operation became far more common in postmenopausal women, possibly due to the growing use of estrogen replacement therapy. Register data can be used for describing changes in clinical practice, but other methods are needed to confirm the causal relationships underlying the changes.     

Tissue expander complications in the pediatric burn patient

OBJECTIVES: The main purpose of our study was to identify the patient characteristics of women undergoing hysterectomy and to estimate the proportion of hysterectomies that could be done vaginally by recognized surgical techniques. STUDY DESIGN: The records of 500 women who underwent hysterectomy were reviewed. The characteristics of patients without an absolute contraindication to vaginal hysterectomy were analyzed. RESULTS: Overall, 96 (19.2%) of our study group underwent vaginal hysterectomy. A total of 382 (76.4%) women were judged not to have an absolute contraindication to this route. The most frequent characteristics of this group were lack of uterine prolapse (76.4%), a myomatous uterus (44.5%), and a need for oophorectomy (43.2%). We did not exclude women who did not have significant uterine prolapse or a history of pelvic surgery or pelvic tenderness and we included those requiring oophorectomy or with a uterine size up to that of 14 weeks' gestation; with these criteria more than two thirds of the entire study population could undergo vaginal surgery. CONCLUSIONS: To maximize the proportion of hysterectomies performed vaginally, gynecologists need to be familiar with surgical techniques for dealing with nonprolapsed uteri, uterine leiomyomas, and vaginal oophorectomy.
