Disclosures that this decade has had the five hottest years ever recorded globally raise concern that extreme temperatures might be associated with higher mortality. An analysis of fluctuations in annual case-specific deaths, seasonal temperatures, and annual income per capita in Massachusetts, Michigan, Washington, Utah, North Carolina, and Mississippi, 1930 to 1985, suggests that, on the contrary, a temperature increase throughout the year was associated with fewer deaths from all causes combined, including deaths from infectious diseases, heart diseases, cerebrovascular diseases, pneumonia, and influenza. An average temperature increase of one degree Fahrenheit was associated with a more than 2 per cent decline in deaths from pneumonia and influenza. The only category of deaths showing no significant association was death from malignant neoplasms. Compared to spring, summer, and fall temperature fluctuations, unusually cold winter temperatures had the strongest fatal effects, but only in North Carolina and Mississippi. The greatest cumulative temperature effects on mortality were found in the same two states. Controlling for annual fluctuations in income per capita did not influence the relationship between temperature and mortality. There was evidence suggesting that the level of wealth ameliorated the fatal effects of extreme temperatures. In conclusion, unusually warm weather was followed by fewer deaths; unusually cold weather, by more deaths.

Comparative Study
OBJECTIVE
To determine if the male cohabiting partner of a woman may serve as a control for exogenous influences on basal body temperature (BBT).
METHODS
Twelve couples from the Atlanta area were enrolled for a total of 41 couple-cycles. Couples recorded their oral temperatures daily and used urinary test kits for luteinizing hormone to estimate the day of ovulation. The covariability between the pre-ovulatory temperature of the women and their partners was assessed. The gaps in the couples' temperatures (female temperature minus male temperature) were compared in the pre- and postovulatory phases.
RESULTS
Considerable covariability was found between temperatures of partners in the pre-ovulatory phase (covariance parameter = 0.49; P <.001). The pre- and postovulatory temperature gaps for all couples were significantly different in size (P <.001). For all couple-cycles, the size of the mean postovulatory temperature gap was at least 0.3-degree Fahrenheit greater than the mean pre-ovulatory temperature gap.
CONCLUSION
Recording the BBT of women's partners may improve interpretation and accuracy of the BBT method. An increase in the size of a couple's temperature gap accompanies the transition from the pre- to the postovulatory phase. By this method, a given couple could determine their unique temperature gap indicating this transition.

A 23 year old Russian male cargo ship crew member arrived in the port of New Orleans after a one month voyage originating in central Africa. During the month at sea, he developed fever up to 103 degrees Fahrenheit which was unsuccessfully managed with the antipyretic, dipyrone. He subsequently developed back and stomach pain, along with diarrhea. Upon the ship's arrival to New Orleans, he was transported to a local hospital where his axillary temperature was 104 degrees Fahrenheit. He was unresponsive, tachycardic and tachypneic with a plasma bicarbonate of 16mmol/L (24-32mmol/L).

Midtrimester abortion was successfully induced in 68 of 69 patients with serial intravaginal administration of prostaglandin E2 suppositories behind a contraceptive diaphragm. The mean abortion time for the successful inductions was 13.07 hours; multiparous patients aborted somewhat faster, mean 12.72 hours, as compared to nulliparous patients, mean 14.22 hours. In 36 patients the PGE2 suppositories were placed behind an intact diaphragm and the mean abortion time was 14.89 hours. In 33 patients the PGE2 suppositories were placed behind a diaphragm modified by having an opening incised in the center, the mean time in these patients was 11.96 hours. Of the 68 successful abortions 59% of the patients aborted in 12 hours or less and 88% aborted within 24 hours. The most frequently encountered side effect was temperature elevation of 2 degrees F or higher which occurred in 68% of the patients. Temperatures returned to normal levels within 4 to 6 hours after the last adminstration of PGE2. Gastrointestinal side effects occurred in 45% of patients, but these side effects were well tolerated and did not require termination of drug administration in any of the patients. Intravaginal administration of PGE2 suppositories is a very effective abortifacient technque during the midtrimester, however the use of PGE2 in conjunction with a diaphragm did not appreciabley improve the technique although the amount of drug administered and the incidence of side effects was somewhat lower than when the PGE2 suppositories are used alone. If a diaphragm is to be used, a modified diaphragm is indicated since it simplifies the clinical management of the abortion, eases administration of the suppositories and permits a more accurate estimation of cervical changes, vaginal bleeding and abortion.

All natural family planning (NFP) methods are based on the determitnation of a woman's fertile period so that a couple may abstain from sexual relations or use a mechanical means of birth control during that time. Researchers are seeking more accurate methods of predicting the onset of ovulation in order to increase the effectiveness of NFP. A new device developed by Dr. Gebhard F.B. Schumacher, a fertility specialist at the University of Chicago who serves on FHI's Technical Advisory Committee, and Dr. Stepen J. Usala, a former medical student at the University's Pritzker School of Medicine, holds the promise of providing a new, cheap, and relatively simple way of predicting ovulation. Called a volumetric vaginal aspirator, the instrument allows women to measure their own vaginal fluid on a daily basis. In early studies of 7 women carefully studied over 18 menstrual cycles, a striking 3 fold to 30-fold increase in the volume of vaginal fluid occurred a few days before ovulation. Results from 12 more women for a total of 26 cycles confirmed the earlier studies. Blood samples were taken in order to measure the levels of estrogen, known to increase prior to ovulation, and luteinizing hormone, which peaks sharply on the day of ovulation, in the women studied. These confirmed that ovulation typically had occurred after the fluid volume increase. In addition, participants recorded their basal body temperature (BBT) upon awakening. Although the BBT does not predict ovulation, it frequently increases by 1/2-1 degree Fahrenheit after ovulation thus serving as an indicator of the end of the fertile period. The prototype of the vaginal aspirator is a disposable plastic syring marked at .05 milliliter intervals so that fluid levels can be easily measured. After the manufacturing process for the aspirator is perfected so that the instrument can be mass produced, Dr. Schumacher hopes that largescale clinical trials will be initiated in the US and abroad. The larger studies and an endocrine study are needed in order for effective rules to be developed for applying the method in either birth control or fertility enhancement. The vaginal aspirator could be useful not only for preventing unplanned pregnancy but also for aiding couples experiencing infertility to pinpoint the time that conception is most likely to occur. As an aid in birth control, the aspirator should have a success rate similar to or better than that of a diaphragm, Dr. Schumacher believes. Although the women testing the vaginal aspirator were ablet to use it without assistance, Dr. Schumacer emphasizes that some patient education will be necessary if it becomes commercially available. Fertility awareness teachers could incorporate it into their courses. Research on the volumetric vaginal aspirator has been supported by FHI and by Mothers' Aid Research Fund of Chicago Lying-In Hospital.

[The investigation of the influence of cryopreservation and inbreeding on the variability of morphological characteristics of the evening-primrose biennial (Oenothera biennis L.)].
The effect of deep freezing of seeds at -196 degrees C (-320.8 degrees Fahrenheit) and inbreeding on the morphological characteristics of the evening-primrose biennal (Oenothera biennis L.), such as the size of plant parts and the amount of fruits, cauline nodes, and generative and vegetative shoots was investigated. The variation coefficients for these characteristics after treatment with low temperatures and inbreeding were calculated. It was shown that the characteristics of plant size show a low and a middle level of variability in the control group. The variation curves for these characteristics are similar to normal distribution curves. After stresses they slightly change or remain invariant. Large adventive shoots show a high level of variability. The distribution of the results in this case significantly differs from the normal. The branching of plants changes after both stress factors: the amount of all kinds of shoots decreases by half or even more.
