Gonadotropins and gonadotropin receptors during the perimenopause.
Twenty-two perimenopausal patients (aged 47-56 years) admitted for elective abdominal hysterectomy and salpingo-oophorectomy were selected to understand better the clinical significance of increasing gonadotropin levels as an indicator of target organ responsiveness. Prior to anesthesia, blood was drawn from the patients for subsequent analyses of serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and 17beta-estradiol (E2) levels. Ovarian tissue was obtained during surgery and frozen at -70 degrees C for subsequent analyses for FSH and LH receptor content. The phase of the menstrual cycle of the patients or postmenopause was determined by serum gonadotropin and E2 levels and histological evaluation of the endometrium. Patients with no detectable FSH receptors showed significantly higher serum FSH and LH levels (4.7- and 4.3-fold, respectively) when compared to patients with detectable FSH receptors; FSH receptors were present in 27% of the patients, LH receptors were present in 68% of the patients and a negative correlation was found between serum LH levels and ovarian LH receptors. In postmenopausal patients, neither FSH receptors nor LH receptors were detectable. High serum gonadotropin levels in perimenopausal patients thus suggest the existence of low or undetectable ovarian gonadotropin receptor levels.

Effect of insulin treatment on serum lipoprotein(a) in non-insulin-dependent diabetes.
In order to evaluate whether Lp(a), a lipoprotein that is potentially thrombogenic and atherogenic, is a potential risk factor for CAD in non-insulin-dependent diabetes (NIDDM), we compared the Lp(a) and its distribution in 145 NIDDM patients with that in 94 healthy control subjects. Furthermore, we studied the effect of insulin treatment on serum Lp(a) in 108 patients with NIDDM. Male and female NIDDM patients had similar Lp(a) concentrations to healthy controls (median value 167 mg L-1, range 15-1550 mg L-1 vs. 157 mg L-1, range 15-919 mg L-1, NS and 92, range 15-1190 mg L-1 vs. 103 mg L-1, range 15-842 mg L-1, NS). Also, the cumulative distribution of Lp(a) did not differ between the NIDDM patients and healthy subjects. Insulin treatment increased Lp(a) in diabetics with a Lp(a) concentration of less than 300 mg L-1, but this effect was not related to the concomitant improvement in metabolic control (mean change (+/- SEM) of HbA1c from 9.80 +/- 0.15 to 8.00 +/- 0.12; P < 0.001). In subjects with elevated Lp(a) concentrations (> 300 mg L-1) the Lp(a) concentration was unaffected by insulin, despite a similar improvement in glycaemic control. These results suggest that insulin may modulate the concentration of Lp(a).

The reproducibility of the Doppler ultrasound measurement of uterine artery vascular resistance.
The intra- and interobserver variation in Doppler ultrasound measurements of uterine arteries (UA) and the variation of pulsatility index (PI) in UA in successive menstrual cycles in the same patient was studied. The intra- and interobserver variability of measurements was similar. In all three series the difference between two measurements was smaller with lower PI values. Cycle-dependent changes, biological variation and random measurement are foremost in causing variability and no systematic error was evident. Doppler ultrasound measurements from UA can be used when patient groups are compared, but in the case of an individual patient, large limits of agreement must be borne in mind.

The association between hormone levels and vascular resistance in uterine and ovarian arteries in spontaneous menstrual cycles--a Doppler ultrasound study.
Ninety-four infertility patients were studied by Doppler ultrasound during spontaneous ovulatory menstrual cycles. The pulsatility index (PI) in uterine and ovarian arteries was measured in the follicular and midluteal phase of the cycle. Associations between high PI values and hormones (estradiol, progesterone, prolactin, testosterone, follicle stimulating hormone) measured during the investigated cycle and age were evaluated. A high PI in uterine arteries in the follicular phase was associated with low estradiol (E2) and progesterone (P) levels in the studied cycle. In the luteal phase PI values of uterine arteries have no obvious association with E and P levels, and other vasoactive compounds influence the perfusion of uterus during this period. The other hormones analysed and age did not correlate with vascular resistance in spontaneous ovulatory cycles.

Vascular resistance in uterine and ovarian arteries: its association with infertility and the prognosis of infertility.
In this study we investigated the blood flow in uterine (u.a.) and ovarian arteries (o.a.) in healthy women and infertility patients and the relationship of vascular resistance to the etiology and the prognosis of infertility. A total of 101 consecutive infertility patients referred to hospital for investigations were studied by Doppler ultrasound. Couples with male infertility were excluded. The control group comprised 19 healthy women having regular menstrual cycle and no history of infertility. The pulsatility index (PI) in o.a. and u.a. was measured in pre- and post-ovulatory phase of the menstrual cycle. The PI values of the controls were compared with those of the patients with various infertility etiologies. The PI values of the infertility patients who subsequently delivered were compared with those of the patients failing to deliver. Infertility patients had high PI in o.a. and u.a. in the luteal phase more often than controls. High vascular resistance in u.a. and o.a. in the luteal phase reduce the take-baby-home rate.

Doppler flow velocimetry of the uterine and uteroplacental circulation in pregnancies complicated by insulin-dependent diabetes mellitus.
UNLABELLED: In forty-three pregnancies complicated by insulin-dependent diabetes mellitus, 16 classified White B, 11 White C, 8 White D and 8 White R or F, the resistance-index (PR index) in the main part of the uterine artery and arcuate uterine arteries was measured by duplex-pulsed wave Doppler ultrasound. Recordings of 24 hours' blood glucose profile and glycosylated hemoglobin were parameters of glycemic control. Vascular resistance in the main uterine artery decreased with proceeding gestation as a non-diabetic pregnancy. The uterine artery supplying the placental had lower resistance than the opposite side, with a mean PR index of 0.559 (SD 0.117) and 0.622 (SD 0.133), respectively. The mean difference between both sides was 0.062 (SD 0.102) (p < 0.001). The uterine artery PR index was slightly higher in the presence of evident morphological vasculopathy, with a mean PR index of 0.591 (SD 0.104) in White D*/R/F diabetics and 0.545 (SD 0.063) in White B/C/D#, respectively (p = 0.148). Additionally more than half of the diabetics without manifest complications (B/C/D#) showed a persistent notch. Long- and short-term glycemic control was unrelated to vascular resistance in the uterine artery, with correlation coefficients of 0.027 (p = 0.746) and 0.051 (p = 0.537) for glucose and HbA1C, respectively. Doppler velocimetry could not predict diabetic specific fetal mobidity. Vascular resistance in the uterine arcuate arteries was significantly lower in the subplacental region, with a mean PR index of 0.367 (SD 0.056) compared to 0.427 (SD 0.064) in areas distant to the placenta (p < 0.0005). It was not related to vasculopathy elsewhere. IN CONCLUSION: in patients with diabetic vasculopathy the uterine artery is also affected, but there is no relationship with long- or short-term parameters of glycemic control. Doppler flow velocimetry of the uterine artery is a poor predictor of diabetes-specific fetal morbidity; if normal ranges of non-diabetic pregnancies are used for reference. Because of significantly different vascular resistance in the two main uterine arteries, mean values of both-side measurements should be used for analysis, whenever possible.

Doppler velocimetry of the umbilical artery in pregnancies complicated by insulin-dependent diabetes mellitus.
The purpose of this study was to investigate vascular resistance by Doppler ultrasound in the umbilical artery of insulin-dependent diabetics longitudinally over the course of pregnancy. Special interest was put on the effects of glycemic control and maternal vascular disease on the flow velocity waveform (FVW) and the predictive value of Doppler flow measurements with regard to perinatal morbidity. Using a duplex-pulsed wave scanner, the resistance-index (PR index) in the umbilical artery was calculated. The mean value of a 24-h blood glucose profile and the concentration of glycosylated hemoglobin (HBA1C) were used as parameters of metabolic control. 53 pregnant diabetic women were examined longitudinally during the course of pregnancy on average on three occasions (range: 1-7) between 17 weeks of gestation and delivery at 37.7 +/- 1.3 (mean +/- SD) weeks. To test the predictive value of Doppler flow velocimetry with regard to perinatal morbidity the results were compared to the FVWs measured in the umbilical arteries of 30 non-diabetic women with normal fetal outcome. Vascular resistance in the umbilical artery of the diabetics declined significantly during the course of pregnancy, with a mean PR index of 0.729 (SD 0.051) at 17 weeks and 0.603 (SD 0.083) at the end of pregnancy (P < 0.002). The majority of PR indices were within the range reported for normal pregnancy and measured in the non-diabetic women. Regression analysis showed no significant correlation between vascular resistance and mean blood glucose level (r = 0.1325) or concentration of HBA1C (r = -0.0519). Maternal vascular disease had no effect on umbilical FVWs.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparison of insulin regimens in patients with non-insulin-dependent diabetes mellitus.
BACKGROUND: Insulin is widely used to improve metabolic control in patients with non-insulin-dependent diabetes mellitus (NIDDM), but there is no consensus about the optimal regimen of insulin treatment. METHODS: We treated 153 patients with NIDDM for three months with five regimens: (1) oral hypoglycemic drug therapy plus NPH insulin given at 7 a.m. (the morning-NPH group), (2) oral hypoglycemic drug therapy plus NPH insulin given at 9 p.m. (the evening-NPH group), (3) NPH and regular insulin (ratio, 70 units to 30 units) given before breakfast and dinner (the two-insulin-injection group), (4) NPH insulin at 9 p.m. and regular insulin before meals (the multiple-insulin-injection group), and (5) continued oral hypoglycemic drug therapy (the control group). RESULTS: The mean (+/- SE) value for glycosylated hemoglobin decreased similarly in all four insulin-treatment groups (1.7 +/- 0.3, 1.9 +/- 0.2, 1.8 +/- 0.3, and 1.6 +/- 0.3 percent, respectively). The decrease was significantly greater in these four groups than in the control group (0.5 +/- 0.2 percent; P < 0.001 vs. all insulin-treated groups). Weight gain was significantly less (1.2 +/- 0.5 kg) in the evening-NPH group than in the other insulin-treatment groups (2.2 +/- 0.5 kg in the morning-NPH group, 1.8 +/- 0.5 kg in the two-insulin-injection group, and 2.9 +/- 0.5 kg in the multiple-injection group; P < 0.05). In addition, the increment in the mean diurnal serum free insulin concentration was 50 to 65 percent smaller in the evening-NPH group than in the other insulin-treatment groups. Subjective well-being improved significantly more in the insulin-treatment groups than in the control group (P < 0.001). CONCLUSIONS: In patients with NIDDM who are receiving oral hypoglycemic drug therapy, the addition of NPH insulin in the evening improves glycemic control in a manner similar to combination therapy with NPH insulin in the morning, a two-insulin-injection regimen, or a multiple-insulin-injection regimen, but induces less weight gain and hyperinsulinemia. The data thus suggest that patients with NIDDM do not benefit from multiple insulin injections and that nocturnal insulin administration appears preferable to daytime administration.

Doppler ultrasound studies in pelvic inflammatory disease.
Ten women with tubo-ovarian abscess caused by pelvic inflammatory disease (PID) were investigated by transvaginal Doppler ultrasound during the acute and healing phases of the infection. The pulsatility index (PI) of the uterine arteries was measured and compared with the values obtained from 19 healthy women. Each control patient was investigated three times during a single menstrual cycle. In PID patients, the PI values were significantly lower than in controls in the same phase of the menstrual cycle. When C-reactive protein was > 50, the PI values were lowest and reverted to normal values when the infection subsided. In a case of chronic infection, the PI did not rise to normal despite normal infection parameters. Doppler ultrasound seems to offer a new method of assessing PID.

Demonstration of tumor necrosis factor-alpha in preovulatory follicular fluid: its association with serum 17 beta-estradiol and progesterone.
In the present study we have measured the concentrations of interleukin-1 beta (IL-1 beta) and tumor necrosis factor-alpha (TNF-alpha) in preovulatory follicular fluid (FF) samples obtained from patients undergoing ovulation induction with human menopausal gonadotropin/human chorionic gonadotropin. In 13 of the 24 (54%) FF samples obtained from 20 patients, TNF-alpha was detected. In contrast, IL-1 beta was observed in none of the 16 samples assessed. In the samples with detectable levels of TNF-alpha, the mean concentration was 40.1 pg/ml (range 20-74 pg/ml). In addition, we found an association between the presence of TNF-alpha in the FF and the serum level of 17 beta-estradiol (E2) and progesterone (P). The E2 and P levels were significantly lower in patients with detectable levels of TNF-alpha in FF than in patients with no detectable TNF-alpha in FF. In summary, the present study shows the presence of TNF-alpha and the absence IL-1 beta in hyperstimulated human preovulatory FF. In addition, our results show an association between the presence of TNF-alpha in FF and low E2 and P levels in serum, suggesting a role for TNF-alpha in the regulation of human steroidogenesis.

Evaluation of the hearing loss associated with cis-platinum treatment by high-frequency audiometry.
The effect of cis-platinum treatment on the hearing of 23 ovarian cancer patients was evaluated using standard and high-frequency audiometry. Twenty-two percent of the patients developed a hearing loss of at least 15 db, 13% in the range 125-8000 Hz and 9% only in the high-frequency area above 8 kHz. However, due to the high-frequency hearing loss (presbyacusis) in older patients high-frequency audiometry was often unobtainable. Hearing screening using standard pure-tone audiometry is recommended for cis-platinum patients as a routine procedure.

Urethral closure function after total and subtotal hysterectomy measured by urethrocystometry.
Urethral closure function was measured before and 3 months after operation in 18 patients having hysterectomy and 13 patients having supravaginal uterine amputation performed. Sixteen patients had a symptom of mild stress incontinence before and 11 after the operation. The urethral closure function at rest and under stress was measured by urethrocystometry. No operation-induced changes in urethral closure pressure, functional length, pressure transmission, urethral relaxation or urethral resistance to stress were found after either operation.

Spontaneous luteinizing hormone surge and cleavage of in vitro fertilized embryos.
The importance of monitoring luteinizing hormone (LH) secretion during gonadotropin stimulation remains controversial. In the present study, the authors evaluated the occurrence of spontaneous LH surges in 170 cycles stimulated by clomiphene citrate and human menopausal gonadotropin, and correlated the success rate of embryo cleavage to the time interval between the occurrence of the LH surge peak value and the time of human chorionic gonadotropin (hCG) administration. LH was quantitated from urine by an avidin-biotin enzyme immunoassay. The results indicated that a spontaneous LH surge occurred in 18% of the cycles. The number of oocytes recovered was not affected by the occurrence of a spontaneous LH surge. In 12% of all cases, the spontaneous LH surge occurred less than 12 hours before the administration of hCG, and in these cases embryo cleavage was not reduced. In 6% of all cases, the spontaneous LH surge occurred over 12 hours before hCG administration, and in these cases embryo cleavage was reduced significantly.

Predicting diabetic retinopathy.
The purpose of this study was to determine the occurrence and severity of diabetic retinopathy and to clarify its association with the duration of diabetes and several other factors in an outpatient diabetic population. The material consisted of 328 diabetics, mainly (77%) C-peptide negative, type 1 diabetics. The mean age of the patients was 45 years, and the mean duration of diabetes was 15 years. Retinal changes were assessed by ophthalmoscopy and widefield fundus photography. All retinopathy was confirmed in 59% and proliferative retinopathy (PR) in 20% of the patients. The frequency of diabetic retinopathy was 15% in patients with diabetes for less than five years but 100% in those with diabetes for 30 or more years. In type 1 diabetics PR was seen only after 10 or more years' duration but, after 20 years' duration it was seen in half of the patients with type 1 and in one-third of the patients with type 2 diabetes. The patients with diabetic nephropathy often had PR. In type 1 diabetics with onset of the disease less than 30 years peripheral sensory neuropathy, coronary disease, hypertension and leg-vessel disease were also often associated with PR. Because one reason for visual handicapping in diabetes is the delay of the diagnosing of vision-threatening lesions screening for treatable retinopathy should be intensive after 10 years' duration and in poorly-controlled diabetics even earlier.
