Application of in vitro fertilisation techniques to obtain calves from valuable cows after slaughter.

The ovaries of two infertile cows of high breeding value were recovered after slaughter, and a total of 222 oocytes were obtained. Of these, 156 were classified as of good or fair quality and were subjected to in vitro maturation, in vitro fertilisation (using frozen semen from three bulls of high breeding value) and in vitro culture procedures. After eight days, 27 embryos were obtained, of which 13 were transferred fresh, and 14 were frozen. Three recipients of fresh embryos became pregnant; two calved and one aborted at four months. One of eight recipients of frozen-thawed embryos became pregnant but aborted at three months.

Cancer of the cervix--old and young, now and then.

A study of two 5-year periods, 1960-1964 and 1982-1986, in Queensland is made. Changing patterns of preinvasive and invasive cervical carcinoma in the world literature are discussed. The age of presentation, stage, histology, and results in Queensland for cervical carcinoma are analyzed. There are over 500 patients in each quinquennium. While the total female population has increased 86%, the maximum increase is in patients under 35 years and over 65. There has been a 50% decrease in the incidence of cervical carcinoma, but a doubling under the age of 30. The stage at diagnosis has markedly improved with 88% stage Ib in the young as opposed to 50% formerly. Late-stage disease remains a problem of the aged. The mortality in both time spans increases with age. Histologic patterns show an increase in nonsquamous patterns and increased mortality in the rare patterns. We have no evidence of the emergence of a rapidly progressive carcinoma in the young. Papanicolaou smear and education programs appear to be preventing cervical carcinoma and allowing diagnosis of the disease at an earlier stage and age. This is reflected in a decrease in mortality from 9.6 per 100,000 (1960-1964) to 4 per 100,000 (1982-1986).

Squamous cell carcinoma arising in a case of vulvitis granulomatosa or vulval variant of Melkersson-Rosenthal syndrome.

A case of vulvitis granulomatosa or the vulval variant of Melkersson-Rosenthal syndrome (MRS) in a young adult patient with systemic lupus erythematosus is presented. She also had evidence of cervicovulvovaginal human papilloma virus (HPV) infection. Nine years later she developed a squamous cell carcinoma (SCC) of the vulva. HPV 6/11 was found by DNA in situ hybridization within a vulval condyloma as well as within the carcinoma. This case is unusual in that SCC associated with HPV 6/11 developed in her vulva affected by MRS rather than in the cervix, where SCC was more likely to occur considering this patient's age.

Epidemic bacteremia due to Acinetobacter baumannii in five intensive care units.

From March 5, 1986 to September 4, 1987, Acinetobacter baumannii (AB) was isolated from blood or vascular catheter-tip cultures of 75 patients in five intensive care units at a hospital in New Jersey. To identify risk factors for AB bacteremia in the intensive care units, a case-control study was conducted. Characteristics of 72 case-patients were compared with those of 37 controls. Case-patients were more likely than controls to have had peripheral arterial catheters (odds ratio (OR) = 7.0, p less than 0.001), mechanical ventilation (OR = 5.8, p less than 0.001), hyperalimentation (OR = 5.7, p less than 0.001), or pulmonary arterial catheters (OR = 3.9, p less than 0.001). Arterial catheters were used with reusable pressure transducers for intravascular pressure monitoring. A logistic regression analysis identified four independent risk factors: transducers, ventilation, hyperalimentation, and days of transducer use at an insertion site. The strongest influence on the risk of AB bacteremia was exerted by number of days of transducer usage. Cultures of 70 transducer diaphragms or domes, 42 in-use and 28 in-storage, were positive for AB in 21% and 46%, respectively. Plasmid analysis showed that patient blood cultures and transducer isolates were identical. Transducers were wiped with alcohol in the units between patient uses. Since reusable transducers appeared to be the source of this outbreak, it is recommended that reusable transducers receive either high level disinfection or sterilization between patient uses.

The relationship between alexithymia and abnormal illness behavior.

The relationship between abnormal illness behavior, measured by the illness Behavior Questionnaire and alexithymia, measured by the Toronto Alexithymia Scale, was studied in four cohorts of subjects. The two measures overlap in that the more alexithymic subjects endorsed more disease conviction, hypochondriacal concern, affective inhibition, affective disturbance, and irritability. Denial was not related to alexithymia, which supports the construct validity of alexithymia. Regression models developed for the four cohorts that consisted of psychiatric outpatients, psychiatric inpatients, medically ill patients and controls differed to suggest that alexithymia state phenomena interact with trait characteristics.

Alexithymia and depressed mood in the psychiatric patient.

The relationship between depressed mood and alexithymia, measured by the Toronto Alexithymia Scale (TAS) was investigated in a group of psychiatric inpatients (n = 81) and outpatients (n = 97). In both cohorts correlations between the TAS and obsessoid personality style were significant when controlled for mood. The obsessoid style, measured by the Hysteroid-Obsessoid Scale was the most powerful predictor of alexithymia in regression models for each cohort. These data suggest that alexithymia is not a function of depression in such psychiatric patients.

A case of tularemia meningitis in Sweden.

Tularemia meningitis occurred in a previously healthy 64-year-old man from Northern Sweden. The patient was immunocompetent and recovered without sequelae. The bacterial isolate conformed by most criteria with the Euro-Asian biovar Francisella tularensis var. palaearctica. Tularemia meningitis may mimic meningitis caused by Mycobacterium tuberculosis.
