high enough for diagnosis. These observations suggest that negative cases may occasionally give positive results, but this is not of much import. The fact that every clinical typhus case which was proved positive by' the Weil-Felix reaction was spotted by the slide method is justification enough for urging the use of this simple technique as a preliminary to putting up a long series of tests by Dreyer's or Felix's method. It was decided to try out a number of slide-negative cases by Dreyer's method, to see whether the zone phenomenon or some other factor would produce positive results in slide-negative cases. Thirty-three such the highest dilution put up was sera were tested; 1 in 250 and the lowest 1 in 25. Of these, 25 were completely negative; the remaining 8 gave agglutinations as shown in table IV.

Results The tests were carried out on Egyptian labourers. Slides were taken in various camps under military control, were brought to the laboratory the same day, and were examined within the' next 24 hours. In all, 640 persons were examined; 11 of these gave 'slide' positive results against OX 19, and 2 were positive to OX 2 in addition. These 13 were then followed up for a complete Weil-Felix reaction, using Dreyer's technique. The results are summarized in table I.

Having established that all positive cases can be detected by the slide method (of course to be confirmed by a complete agglutination test), and that the slide-negative cases will not give a positive result by Dreyer's method, it is. a reasonable assumption that a complete Weil-Felix test need not be done unless the slide test is positive. If this procedure is followed the obvious advantages will be : (a) economy in material and time; (b) avoidance of unnecessary bleeding of the patient; and (c) easier despatch of slides, as compared with that of blood or serum, to a laboratory situated at a distance from the hospital.

At the present time there is no reliable anterior pituitary preparation available for use which can simulate the actions of the naturally occurring gonadotrophs hormone; there are, however, two preparations which are of considerable therapeutic value, namely, serum gonadotrophs hormone prepared from pregnant mare's serum, and urine or chorionic gonadotrophic hormone extracted from pregnancy urine. The former stimulates follicular development; the latter causes corpus luteum formation. A combination of these two preparations forms a useful therapeutic agent indicated in conditions directly or indirectly associated with defective action of the anterior pituitary gland. The

There is one condition, however, namely, vulvo-vaginitis, which can be effectively treated by cestrogenic hormone in the form of vaginal pessaries or by oral administration. The oestrogens stimulate the growth of the vaginal epithelium, and with the resulting increased glycogen content of the cells additional lactic acid is available so that not only is the infection controlled by the shedding of the epithelial squames, but the increased acidity of the vaginal flora proves inimical to the causative organism. It should be noted that the sulphonamides, especially sulphathiazol and sulphadiazine, are also effective in this condition and have none of the minor disadvantages, such as enlargement of the breasts, which are sometimes associated with the administration of the As the

hsemorrhagica and, pending more potent anterior pituitary preparations, it is the one most likely to meet with success, but the dosage must be adequate and the treatment must be energetic if satisfactory results are to be obtained. The intramuscular injection of 5 to 10 mg. of progesterone daily until the bleeding is controlled has been found to be an effective dosage. The role of the (Estrogenic hormone in functional uterine bleeding has recently been investigated, and not unfavourable .results have been reported. The results obtained in cases of irregular' uterine bleeding treated by oestrogenic hormone, and later referred to me, have been uniformly unsatisfactory.

hormones

The ovarian hormones are cestradiol or cestrogenic hormone elaborated by the developing Graafian follicles, and progesterone secreted by the corpus luteum not only elaborates its specific hormone, progesterone, but it also secrets cestradiol. Progesterone and cestradiol are the true or naturally occurring hormones of the ovaries and are produced for the most part by the ovaries under the stimulus of the gonadotrophic hormone of the anterior pituitary; they, are also secreted in variable amounts by other internal secretory glands, such as the adrenals. Potent preparations of these hormones have been available for some time. Now we have available for clinical use synthetic preparations of cestrogenic hormone, such as diethyl hexcestrol and triphenylchloroethylene stilbcestrol, which, though not chemically related, simulate closely the actions of the naturally occurring hormones. They, have the added advantage of being active when given

life. It is characterized by a long intermenstrual period, five to ten weeks, followed by excessive and prolonged menstrual loss. It is possible that a minor psychological disturbance, acting through the higher cerebral centres and interfering with anterior pituitary function, forms the predominant etiological factor in metropathia hsemorrhagica. The essential cause of the condition, however, is a failure of ovulation with concomitant excessive production of the (Estrogenic hormone.

with ovulation. It is believed to be due to a transient diminution of the oestrogenic hormone concentration occurring between the time of ovulation and mobilization of the corpus luteum. The temporary drop in the amount of circulating oestrogenic hormone results in a diminished stimulation of the uterine endometrium, which partially breaks down and causes bleeding. In some the bleeding may be very slight and represented by only a few spots, whilst in others the amount of blood lost may be similar to that of the normal period. Owing to the danger of inhibiting directly the anterior pituitary and indirectly ovulation, cestrogenic hormone is contra-indicated in this condition. The stimulation of the endometrium can, however, be adequately maintained in such cases by giving 5 mg. progesterone intramuscularly the day before the expected bleeding and for two days thereafter. A course of therapy over three menstrual cycles is usually efficacious. Hypomenorrhcea, or scanty menstrual loss, is not common and in most cases it is of no serious significance, as in such cases there is usually no failure of ovulation. There are a few cases, nevertheless, iu which there is failure of ovulation, and in such the bleeding is associated with the proliferative phase of the endometrium?so-called anovular menstruation. The importance of this type of menstruation in sterility is evident. An effective therapy must promote follicular maturation and ovulation; this can only be done by administration of anterior pituitary hormone, particularly the serum gonadotroph^ hormone, given in doses of 200 international units every third day for five injections, starting at the onset of the menstrual

period. Oligomenorrhoea,

or delayed menstruation, is not It is a frequent precursor of functional amenorrhcea and is prone to occur at the beginning and end of the period of reproductive life. Towards the menopause the bleeding is frequently associated with a proliferative endometrium, but at other times for the most part it is associated with a secretory endometrium. Thus there is a long proliferative phase of the endometrium and a normal secretory phase. The therapy indicated is one which will accelerate follicular development and ovulation; accordingly, the treatment most likely to be effective is the administration of anterior pituitary in the form of serum gonadotrophs hormone (200 i.u.) alone or in combination with urine gonadotrophic hormone (100 i.u.) every third day for five injections at the onset of the period. These preparations should be. given over three menstrual cycles at the time corresponding to the pre-ovulatory uncommon.

(Estrogenic hormone therapy is often eminently successful in these resistant and difficult cases. It may be necessary to give a very high dosage if no result is obtained with a moderate dose. It should be noted, however, that it is not advisable to give a high dosage over more than a short interval of time. One case treated did not react favourably until a dosage of 45 mg. of synthetic oestrogen was given daily for seven days. The pruritis of was completely relieved. This high dosage oestrogen, however, provoked such a marked hypertrophy of the vaginal epithelium as to form a plaque in the anterior wall. Cystoscopic examination suggested a malignant condition of the base of the bladder, but the vaginal mucosa eventually returned to its normal post-menopausal state. The patient remained free of irritation until a recurrence two weeks ago. The most common etiological factor responsible for post-menopausal bleeding is a malignant condition of the uterus or its adnexa. It cannot be emphasized too strongly that post-menopausal bleeding, per se, is never an indication for cestrogenic hormone therapy, yet one frequently finds it being given quite unjustifiably in this condition. Some women may have an uneventful climacteric but complain of subjective symptoms late in life similar to those experienced at the menopause. Such cases can be effectively treated with the cestrogens, but they usually require a small maintenance dose

conditions

The corpus luteum hormone or progesterone has welldefined physiological actions in the initiation and continuation of pregnancy. It is responsible for the the of uterine reaction decidual endometrium, thus preparing the endometrium for the nidation of the fertilized ovum. Its sedative action on the uterine musculature promotes conditions favourable for the the early process of embedding of the ovum and development of the placenta, and its uninterrupted production is essential for the continuation of the pregnancy. Consideration of these facts suggests the usefulness of progesterone therapy in (1) repeated early miscarriage suspected when the period is a few days late, (2) threatened abortion, and (3) recurrent abortion.

(1) Early

miscarriage?This

occurs

without the patient's knowledge, or it may be suspected when the period is repeatedly but not continuously a few days late. Some women realize intuitively that conception has occurred. A continuation of the pregnancy in such cases can be brought about by-the administration of progesterone, 5 to 10 mg. twice weekly, begun during the second half of the menstrual cycle and continued until at least the fourth month is reached. (2) Threatened abortion.?Abortion most frequently occurs at the time of the suppressed period, and it reaches its highest incidence at the time of the third missed period. The explanation for the frequency of abortion at. the third month is not clear. The placenta, by the time this stage is reached, is fully developed. It is known that pregnancy can continue /when the corpus luteum of pregnancy is removed at an early stage. The assumption is, therefore, that the placenta secretes the necessary amount of progesterone required for the continuation of the pregnancy. The change over from corpus luteum to placental production of _

progesterone probably takes place at the third month. A lag in the change over,' resulting in a lowering of the progesterone threshold, would furnish an explanation of the frequency of abortion at this time. The administration of progesterone in large doses (10 to 20 mg. daily) at the very earliest stage of a threatened miscarriage is frequently effective in saving the pregnancy. If much placental separation has occurred, however, the abortion will become inevitable and progesterone therapy is then valueless. It should be noted that progesterone therapy alone in threatened miscarriage is not enough; rest must be enforced and anxiety allayed by the use of sedatives. of administration (3) Recurrent abortion.?The progesterone early in pregnancy has resulted in the

continuation of the pregnancy to term in many cases of recurrent abortion. An adequate dosage, such as 5 to 10 mg. twice weekly, must be given as soon as the pregnancy is diagnosed and continued until at least the end of the fourth month of pregnancy. It is advisable to supplement this therapy by the administration of vitamin E. The cestrogens, in virtue of their function of increasing the sensitivity of the uterine muscie, have been used in (a) missed abortion, (b) induction of labour, and (c) uterine inertia. (a) Missed abortion.?As is well known, a dead ovum may be retained in utero for intervals of time varying from weeks to months. The cause of the retention of the ovum is presumably the diminished sensitivity of the uterine muscle. This can be overcome by the administration of cestrogens, and this form of therapy is frequently very successful in missed abortion ?tfid premature death of the fcetus. As the cestrogens are fairly rapidly destroyed in the body, it is suggested that a high dosage should be given over a short interval of time. I have obtained satisfactory results with 10 mg.. of synthetic oestrogen given hourly for six to ten hours, supplemented in some cases by posterior pituitary extract. This high dosage is well tolerated. The more advanced the pregnancy the more successful is this form of treatment. (b) Induction of labour and -premature death of fcetus.?When giving alone the cestrogens are rarely effective in inducing labour but when employed as part of a scheme of induction they may be of value, although their usefulness in these cases is difficult to assess. They are, however, efficacious in the induction of labour in cases where the fcetus dies in utero near term, and also in some cases of premature rupture of the membranes associated with delay in the onset of labour. (c) Uterine inertia.?The cestrogens have been found to be effective in more than half of a series of cases of uterine inertia. In my experience the results of this form of therapy have been inconclusive, as it has not been found possible to induce increased uterine sensitivity in many 'cases in which the indications for its use appeared to be specific and in which a satis-

op lactation

The development of the breasts during pregnancy in preparation for lactation is brought about by the actions of the (Estrogenic and corpus luteum hormone. The secretion of milk in the breasts on the third or fourth day of the puerperium is due to prolactin or mammotrophic hormone of the anterior pituitary gland, whilst the continuation of milk production is associated with the stimuli arising from the act of suckling. During pregnancy and for the first two or three days of the pueipierium the mammotrophic hormone of the anterior pituitary is probably inhibited by the high blood concentration of the cestrogenic hormone; the delivery of the placenta results in the release of this inhibition. The administration of cestrogens, however, either before or after lactation is established, can again bring about the inhibition of the anterior pituitary milk secreting hormone; the breast either does not secrete milk or its secretion quickly subsides with this therapy, provided suckling _

does not take place. As the administration of cestrogens to a nursing mother does not inhibit the secretion of milk, it would seem that the reflex act of suckling must stimulate the .increased secretion of prolactin.

The important part played by the act of suckling in hormone production, leading to milk secretion, suggests how readify the endocrine system is influenced by nervous stimuli. In cases where breast feeding is contra-indicated, oestrogen therapy should be started the day after delivery. It is advisable to give an effective dose initially?5 mg. thrice daily for four days, followed by 5 mg. daily for six days is usually effective?in order to produce .complete inhibition of the lactogenic hormone. Lactation can be inhibited in eveiy case provided the dosage is adequate; the puerperal patient can tolerate a high dosage of cestrogenic hormone. The chemist has provided us with potent preparations, and it behoves us as clinicians to realize that the indications for their use must be defined and limited, and that their misuse may be fraught with serious consequences. Intelligently and wisely used, they can be of inestimable value.
