    Treatment of cervical intraepithelial neoplasia by colposcopically directed cryosurgery and subsequent pregnancy experience (1982)

    Notes: Summary. Of 420 patients attending a colposcopy clinic 204 were treated with outpatient cryosurgery for cervical intraepithelial neoplasia. It was possible to assess a definite outcome of therapy in 159 patients, and the lesion was successfully eradicated in 87% of them. Treatment failure appeared to be more common in patients of high parity, when the lesion extended into the cervical canal, and in those patients with large lesions. Failure appeared to be unrelated to patient age and to the histological grade of the lesion. In subsequent pregnancies utero-cervical function was preserved.

    A CASE OF CLEAR CELL ADENOCARCINOMA OF THE VAGINA IN PREGNANCY (1981)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: The case is described of a 20 year old pregnant woman with clear cell adenocarcinoma of the vagina who had been exposed to diethyl stilboestrol in utero. This is the second of three cases known to have occurred in Britain. The importance of radical treatment is discussed. Neither cervical nor vaginal intra-epithelial neoplasia were seen histologically, although squamous metaplasia was widespread, and in some areas was immature and showed atypical features which could be misinterpreted as intra-epithelial neoplasia. An area of atypical adenosis was noticed, a hitherto rarely observed feature.

    Plasma progesterone levels as an index of ovulation (1983)
    Oxford, UK : Blackwell Publishing Ltd
    BJOG 90 (1983), S. 0 
    Details

    Topics: Medicine
    Notes: Summary. Plasma progesterone levels were measured in three groups of untreated women. (1) Nine women with follicle rupture, proved by laparotomy or laparoscopy, had values of ≥40 nmol/l on days 18–24 (days −10—5 from the next period); thus a value of 〈40 nmol/1 should not be taken as evidence of ovulation. (2) Nineteen healthy women with normal menstrual histories had hormone assays on alternate days during one cycle. In five of them all values were 〈38 nmol/1. (3) Forty women had a single progesterone assay on days 20–29 of a conceptual cycle. Eight of them had a level 〈40 nmol/l. Ovulation had certainly occurred in all of them, but it is difficult to assess whether the sample timing was optimal since there was no following menstrual period. Progesterone levels in drug-induced conceptual cycles were in general higher than those in spontaneous pregnancy cycles. Women with luteinization of the unruptured follicle frequently had values of 〉40 nmol/l. Conversely, a secretory endometrium was not uncommon in cycles with values of 〈38 nmol/l.

    X-Ray and microwave observations of active regions (1983)

    Notes: Abstract We compare coordinated, high spatial resolution (2–3 arc sec) observations at 6 cm and in soft X-rays with photospheric magnetograms and optical filtergrams of two active regions. The correspondence of the brightest centimetric components in these regions with coronal loops, sunspots and pores, chromospheric structures and the photospheric magnetic field was determined. Our principal results are: The association between the microwave components and coronal X-ray and photospheric magnetic field structures is complex; in general X-ray emission was not associated with the microwave components. A majority of the components were not associated with sunspots, although the brightest (T b ≥ 4 × 106 K) components overlay regions of strong photospheric field or high field gradients. Several of the components coincided with the apparent bases of shorter coronal loops and 4 with the tops of X-ray loops. The X-ray and magnetic field observations are used to constrain possible centimetric emission mechanisms. Thermal bremsstrahlung can not be a significant contributor to this bright microwave emission. Thermal gyro-resonance absorption is consistent with some of the observations, but untenable for those components which are bright in microwaves, lack X-ray emission, and overlie regions of weak magnetic field. As an explanation for the brightest (T b ≥ 4 × 106 K) components, the g-r theory requires coronal loops with significant currents but very low densities. Alternatively, a nonthermal mechanism implies that the emission arises from the transition region and suggests that discrete regions of continuous particle acceleration may be common in active regions.

    Observations of the reappearance of polar coronal holes and the reversal of the polar magnetic field (1984)

    Notes: Abstract We examine observations relating to the evolution of the polar magnetic field around sunspot maximum, when the net polar flux reverses polarity and coronal holes redevelop around the poles. Coronal hole observations during the last two solar maxima are examined in detail. Long-term averages of the latitudinal dependence of the photospheric magnetic field and the evolutionary pattern of the polar crown filaments are used to trace the poleward motion of the reversal of the large-scale surface field, and are compared to the redevelopment of the polar holes. The polar holes evolve from small, mid-latitude holes of new-cycle polarity which expand poleward until they join and cover the pole. We find that the appearance of these mid-latitude holes, the peak of flux emergence at low latitudes, and the polar polarity reversal all occur within a few solar rotations. Lagging 6 months to 1 1/2 yr after this time, the polar crown disappears and the polar holes redevelop. These results are examined in the context of phenomenological models of the solar cycle. We believe the following results in particular must be accounted for in successful models of the solar cycle: (1) The process of polarity reversal and redevelopment of the polar holes is discontinuous, occurring in 2 or 3 longitude bands, with surges of flux of old-cycle polarity interrupting the poleward migration of new-cycle flux. There is a persistent asymmetry in these processes between the two hemispheres; the polarity reversal in the two hemispheres is offset by 6 months to 1 1/2 yr. (2) Contrary to the Babcock hypothesis, the polar crown disappears months after the magnetic polar reversal. We suggest one possible scenario to explain this effect. (3) Our observations support suggestions of a poleward meridional flow around solar maximum that cannot be accounted for by Leighton-type diffusion.

    The spatial distribution of 6 centimeter gyroresonance emission from a flaring X-ray loop (1984)

    Notes: Abstract We compare simultaneous high resolution soft X-ray and 6 cm images of the decay phase of an M3 X-ray flare in Hale Region 16413. The photographic X-ray images were obtained on an AS & E sounding rocket flown 7 November, 1979, and the 6 cm observations were made with the VLA. The X-ray images were converted to arrays of line-of-sight emission integrals and average temperature throughout the region. The X-ray flare structure consisted of a large loop system of length ∼ 1.3 arc min and average temperature ∼8 × 106 K. The peak 6 cm emission appeared to come from a region below the X-ray loop. The predicted 6 cm flux due to thermal bremsstrahlung calculated on the basis of the X-ray parameters along the loop was about an order of magnitude less than observed. We model the loop geometry to examine the expected gyroresonance absorption along the loop. We find that thermal gyroresonance emission requiring rather large azimuthal or radial field components, or nonthermal gyrosynchrotron emission involving continual acceleration of electrons can explain the observations. However, we cannot choose between these possibilities because of our poor knowledge of the loop magnetic field.
