Assessment of the current performance of grazing infrastructure across Irish dairy farms.

The increased average Irish dairy herd size in a post-quota environment has put heightened pressure on grazing infrastructure. In a rotational grazing system, grazing infrastructure consists of the paddock system, which delineates the grazing areas into appropriately sized grazing parcels, and the roadway network, which connects these paddocks to the milking parlor. Where herd size has increased without corresponding adaptations to the infrastructure, farm management and roadway network performance has been affected. The links between suboptimal grazing infrastructure and roadway network efficiency are poorly understood and not widely documented. The aims of this study were to (1) analyze the effect of herd expansion and paddock size on pasture allocations per paddock, (2) identify the factors that affect the total distance walked per year, and (3) create a metric to compare the efficiency of roadway networks across farms of varying grazing platforms. A sample population of 135 Irish dairy farms with a median herd size of 150 cows was used for this analysis. Herds were split into the following 5 categories: <100 cows, 100 to 149 cows, 150 to 199 cows, 200 to 249 cows, and ≥250 cows. Herds with ≥250 cows had a greater number of paddocks per farm and rotated around the grazing paddocks more frequently, with 46% of paddocks only suitable for 12 h allocations relative to herd size, compared with just 10% to 27% of paddocks for herds with <100 cows to herds with 200-249 cows. When predicting the total distance walked per year on each study farm, the mean distance from a paddock to the milking parlor was the strongest indicator (R2 = 0.8247). Other metrics, such as herd size, have failed to account for the location of the milking parlor relative to the grazing platform. The creation of the relative mean distance from a paddock to milking parlor (RMDMP) metric allowed the calculation of a farm's roadway network efficiency for moving the herd between paddocks and the milking parlor. The analyzed farms increased their efficiency in terms of RMDMP (0.34-40.74%) as they increased herd size post quota. However, the position of new additional paddocks relative to the milking parlor substantially affected their RMDMP.

Use of the CEEA stapler to avoid ultra-low segmental resection of a full-thickness rectal endometriotic nodule.

A woman with a history of numerous surgical episodes for treatment of aggressive endometriosis experienced rectal symptoms. She was prepared for the possibility of laparotomy with or without colostomy to relieve her symptoms. After extensive laparoscopic dissection of the rectovaginal septum, a circular stapling device (Premium Plus CEEA; Autosuture, Melbourne, Victoria, Australia) was used to excise completely an anterior rectal lesion that otherwise would have resulted in ultra-low rectal resection and anastomosis. Morbidity associated with the latter procedure was avoided; the patient was discharged within 72 hours and experienced no early or late complications. Postoperative barium enema was obviated by rapid return to normal bowel habits and complete resolution of dyschezia and dyspareunia.

Age effects on the clinical presentation of alcoholics at a psychiatric hospital.

Little is known about the effects of age on the clinical presentation of alcoholism in various treatment settings, despite the clinical importance of this factor. This study evaluates the effects of age on the clinical profile of 604 alcoholics who presented for initial evaluation and treatment at a psychiatric hospital. Young alcoholics displayed the most prominent substance use, antisocial behavior, depressive symptoms (including suicidality), and impulsivity. Early middle-aged alcoholics displayed the highest levels of drinking. Elderly alcoholics displayed the highest levels of cognitive dysfunction, although some level of cognitive dysfunction was present among even the youngest alcoholics. These findings confirm and clarify the effects of age on the clinical profile of alcoholics presenting for initial evaluation at a psychiatric hospital.

Laparoscopic hysterectomy.

The terminology of laparoscopically-assisted hysterectomies needs to be simplified and clarified. Laparoscopic hysterectomy should be used as a general term, whereas operative laparoscopy before hysterectomy, laparovaginal, laparoscopic total and subtotal hysterectomy should be used to describe the types of laparoscopic hysterectomy. The complication rates from laparoscopic hysterectomy, abdominal hysterectomy and vaginal hysterectomy are similar. The lower febrile morbidity after laparoscopic hysterectomy may be due to improved pelvic visualization compared to vaginal and abdominal hysterectomy. Controlled trials show that laparoscopic hysterectomy has advantages over abdominal hysterectomy which include reduced pain, reduced hospitalization time and earlier return to work. Most abdominal hysterectomies can be replaced by laparoscopic or vaginal hysterectomies. Whether this happens will depend upon adequate training facilities.

Lost surgical specimens.

It is an unfortunate fact that surgical specimens can become lost in the peritoneal cavity. Several reparative actions may be required, including laparotomy. The preferred method to avoid this complication, however, is to prevent it from occurring.

Direct cannula entry for laparoscopy.

The common blind puncture technique for inserting a cannula to establish pneumoperitoneum was first described by Veress in 1938 and carries several significant and specific complications such as gas embolism, subcutaneous inflation, failed pneumoperitoneum, and bowel or visceral insufflation. Direct cannula insertion is both safe and effective. No major complications using this technique occurred in a series of 550 consecutive laparoscopies. It would seem that the patient who is served safely by a Veress needle approach is equally served by direct cannula entry.

Racial effects on the clinical presentation of alcoholics at a psychiatric hospital.

Despite the clinical importance of race effects on comorbidity and symptom patterns in recent community studies, little is known about such effects in various treatment facilities. This study evaluated the effect of race on the clinical profile of 604 alcoholics who presented for initial evaluation and treatment at a psychiatric hospital. The factor that most strongly distinguished the racial groups was socioeconomic status (SES). After controlling for SES and other factors, no significant difference was noted between ethnic groups in the prevalence of major depressive disorder (MDD) or antisocial personality disorder. However, after controlling for SES and other factors, alcohol and drug use were more severe in African-American alcoholics, along with four symptoms associated with alcohol and drug use. In contrast, reversed neurovegetative symptoms, anxiety-related symptoms, and some personality-related symptoms were more severe in white alcoholics.

Endoscopic minilaparotomy.

In a preliminary study the principles of standard gynaecological surgery, new operative laparoscopic techniques and mechanical elevation of the abdominal wall are combined. These early results indicate an advantage to both patient and hospitals from this approach. Further studies are required to verify our impressions that minilaparotomy combined with no insufflation laparoendoscopy will open up the concept of operative laparoscopic surgery to most gynaecologists.

Instruments and equipment used in operative laparoscopy.

Successful operative laparoscopy is dependent on the proper use and knowledge of a variety of appropriate surgical equipment. This chapter describes cameras, light sources, videos, video positioning, operating tables, anaesthesia, insufflators, laparoscopes, trocars, irrigators, forceps, scissors, electrosurgical instruments, lasers, suturing, staples and uterine manipulators. Knowledge of the best choice and proper use of instruments has a more important role in performing operative laparoscopy than laparotomy.

Laparoscopic hysterectomy.

Laparoscopic hysterectomy is a substitute for abdominal hysterectomy and not for vaginal hysterectomy. Most hysterectomies currently performed with an abdominal approach may be performed with laparoscopic dissection of part or all of the abdominal portion followed by vaginal removal, including fibroids of 1000 g. There are many surgical advantages, particularly magnification of anatomy and pathology, easy access to the vagina and rectum, and the ability to achieve complete haemostasis and clot evacuation during underwater examination. Patient advantages are multiple and are related to avoidance of a pain producing abdominal incision. They include a reduced period of hospitalization and recuperation and an extremely low rate of cuff infection and ileus. It must be emphasized that conversion to laparotomy when the surgeon becomes uncomfortable with the laparoscopic approach should never be considered a complication; it is rather a prudent surgical decision that will profoundly decrease patient risk. The laparoscope can be used in combination with hysterectomy in a variety of ways with significant surgical and patient advantages. With few exceptions, laparoscopic hysterectomy can replace abdominal hysterectomy. Surgical outcome is the same. In experienced hands, the complication rate is low. Patient benefits are related to avoidance of an abdominal incision and include improved cosmetics and more rapid recovery.

Gasless laparoscopy--useless or useful?

Carbon dioxide (CO2) pneumoperitoneum for advanced operative laparoscopy has well-documented inherent pathophysiologic risks. Problems are associated with creating and maintaining the pneumoperitoneum, lowering body temperature, infective particles in the insufflation gas, and ensuring hemostasis of port entry sites after intraabdominal pressure is reduced. When the vagina is opened to remove surgical specimens or at the time of hysterectomy, loss of vision occurs. In some patients general anesthesia and CO2 pneumoperitoneum are contraindicated, and in them such problems could be avoided by gasless laparoscopy. Three types of mechanical anterior abdominal wall elevators have been used at the Melbourne Gynoscopy Centre for a variety of laparoscopic procedures, all of which have their advantages and disadvantages.

Complications of laparoscopic hysterectomy.

Although laparoscopic hysterectomy is now being performed worldwide, few reported data are available on the associated morbidity and mortality. Between December 1990 and September 1993, 220 women underwent laparoscopic hysterectomy at the Melbourne Gynoscopy Centre. Complications occurred in 35 (15.9%). Among these were anterior abdominal wall vessel injury in 5 patients, bladder injury in 5, febrile illness in 13, secondary hemorrhage in 4, temporary ureteral obstruction in 4, and Richter hernia in 1.

Laparoscopically assisted hysterectomy.

OBJECTIVE: To determine the feasibility and effectiveness of laparoscopically assisted hysterectomy. DESIGN: A prospective study of the planned surgical procedure was carried out by two teams, each with two gynaecologists, who were experienced in operative laparoscopy. SETTING: The operations were carried out in a private hospital, where advanced operative laparoscopy equipment was available. PATIENTS: Seventeen patients were selected for the procedure, all of whom required hysterectomy for symptoms of pain or menorrhagia in association with uterine or other pelvic disease. Patients with carcinoma or uterine enlargement beyond 12 cm were excluded. PROCEDURE: Laparoscopically assisted hysterectomy was carried out by means of a video monitor, uterine manipulation by vaginal instrumentation, three or four abdominal punctures of less than 1 cm, and bipolar diathermy to secure vascular pedicles. The uterus was removed from the vagina by cutting vaginal skin and the cardinal ligaments. RESULTS: The operating time was 90-220 min, the blood loss was 30-200 mL, and the hospital stay lasted two to five days and convalescence two to four weeks. No serious complications occurred. CONCLUSIONS: Laparoscopically assisted hysterectomy may be valuable when adnexal or uterine abnormalities are present and vaginal hysterectomy is either contraindicated or more difficult. The procedure requires special equipment and may only be carried out by experienced gynaecological operative laparoscopists. Its acceptance will depend upon reducing the operating time to less than 90 min. It has the advantage of reducing the duration of hospital stay and the duration of convalescence when compared with abdominal hysterectomy.

Transcervical endometrial resection for abnormal uterine bleeding--report of 100 cases and review of the literature.

Many Australian women suffer from unacceptable uterine bleeding and up to 40% may undergo hysterectomy for benign conditions which may be better treated by a less radical procedure--endometrial resection. The preliminary results of 100 patients treated in this way are presented.
