Intravenous administration of local anaesthetics has repeatedly been recommended for the treatment of chronic pain. Some authors have also reported on their use in postoperative pain management. However, most of these publications are case reports or refer to rather old studies or investigations based on study designs that fail to meet present scientific standards. ⋯ During the first 24 h after surgery 12 patients in the lidocaine group required a total of 550 mg meperidine in addition, while 8 patients in the control group required a total of 300 mg meperidine. The postoperative meperidine consumption was not significantly diffent between the lidocaine group and the control group. Intravenous lidocaine infusion did not significantly reduce postoperative pain after tonsillectomy in the dosage used.

Serogroup B Neisseria meningitidis is the most common cause of epidemic meningococcal disease in developed countries. Until recently no vaccine has been available for prevention of infection with this organism. In an attempt to control epidemic serogroup B meningococcal disease in greater Sao Paulo, Brazil, during 1989 and 1990, a Cuban-produced outer-membrane-protein-based serogroup B meningococcal vaccine was given to about 2.4 million children aged from 3 months to 6 years. ⋯ Between June, 1990, and June, 1991, 112 patients and 409 matched controls with confirmed vaccine status were enrolled. Estimated vaccine efficacy varied by age: 48 months or older = 74% (95% Cl 16 to 92%), 24 to 47 months = 47% (-72 to 84%), and less than 24 months = -37% (< -100 to 73%). Our results suggest that the Cuban-produced vaccine may be effective for prevention of serogroup B meningococcal disease in older children and adults.

To correlate deep bacterial infections with HIV infection and evaluate the influence of HIV on clinical picture and outcome in patients with meningitis, pneumonia or pyomyositis. ⋯ These results show a strong association between pyomyositis, pneumonia and HIV infection. They also indicate an increased mortality associated with HIV infection in patients with pyogenic meningitis, especially pneumococcal meningitis. Pyomyositis should be considered an indicator of stage III HIV disease in the proposed WHO clinical staging system.

Interruption of endometrial maturation without hormonal changes by an antiprogesterone during the first half of luteal phase of the menstrual cycle: a contraceptive potential.
To examine hormonal and endometrial responses to intermittent low-dose RU486 administration in the luteal phase of the menstrual cycle. ⋯ Two low doses of RU486 given 72 hours apart during the luteal phase of the cycle disrupted ongoing endometrial maturation without altering the hormonal and time course of the menstrual cycle. This study provides a basis for the development of a novel form of luteal contraception.

A study of cholelithiasis during pregnancy and its relationship with age, parity, menarche, breast-feeding, dysmenorrhea, oral contraception and a maternal history of cholelithiasis.
We prospectively studied 512 consecutive women attending the antenatal clinic of the Rotunda Hospital of Dublin, Ireland, to assess the prevalence of gallstones among them and to describe the characteristics of those women found to be gallstone-positive (group 1), compared with the negative-control population (group 2). Real-time ultrasound scanning of the pelvic area was extended to the upper part of the abdomen. Cholelithiasis was detected in 23 patients. ⋯ Also, early pregnancies, age at menarche and oral contraception did not have any significant difference between the two groups. However, we recorded a significantly higher prevalence of cholelithiasis in older women and in patients with dysmenorrhea. A positive trend was found in patients who had a history of previous breast-feeding and in women with a positive maternal history of symptomatic gallstones.
