Percutaneous Treatment with a Mucopolysaccharide Polysulphate of Experimentally Induced Subcutaneous Haematomas in Man

In a double blind trial on ten healthy volunteers, the efficacy of a topically applied mucopolysaccharide polysulphate* in the treatment of subcutaneous haematomas was assessed. Standardized haematomas were induced by subcutaneous injection of a mixture of autogenous blood and 125I-fibrinogen. The absorption of the haematoma, expressed as the removal of the labelled fibrin(ogen), could thus be objectively measured by the decrease in radioactivity.

The results show an exponential absorption of these haematomas. The absorption time was reduced to about half compared with placebo, when treated topically with mucopolysaccharide polysulphate. The difference is statistically highly significant and is also considered clinically relevant.

Effect of predilatation of the uterine cervix by laminaria tent on activity of the placenta

Serum concentrations of hCG were determined in blood samples taken 18-20 h and immediately before vacuum aspiration in 45 women in gestational weeks 7-9, admitted for legal abortion. In 35 of the women, a laminaria tent was inserted for cervical dilatation immediately after the first blood sampling. Serum hCG values decreased significantly in the women pretreated with laminaria tent, but were unchanged in the untreated women. This finding may indicate that pretreatment with a laminaria tent induces a partial placental detachment.

The effect of mediolateral episiotomy at delivery on pelvic floor muscle strength evaluated with vaginal cones

In a prospective study, pelvic floor muscle strength was investigated pre- and post partum in 87 women with uncomplicated pregnancies. Those vaginally delivered were 71 primiparas, while 16 underwent an elective cesarean section. The objective was to evaluate the effect of the delivery procedure on the pelvic floor muscle strength with the aid of vaginal cones. In the group of women with vaginal delivery three subgroups were identified: episiotomy, spontaneous laceration and intact perineum. Pelvic floor muscle strength was weakest in the episiotomy subgroup, the difference in values between this subgroup and each of the other subgroups and the elective cesarean section group being significant. No significant difference was evident between the spontaneous lacerations and intact perineum subgroups.

Proctosigmoidoscopy in primary health care

Of 282 patients who underwent rigid proctosigmoidoscopy (PSS) in primary care in the city of Västerås during 1985, 5.7% had polyps or tumours in the rectum. Barium examination of the large bowel was performed on 194 of these 282 patients and showed polyps or tumours in 6.2%. Use of these two methods led to diagnosis of polyps or tumour in the large bowel in 9.6% (27/282). Polyps were found by both methods in only one patient. Of four patients with tumours, two were discovered by barium examination and two by PSS. Barium examination and PSS complement each other in the search for polyps and tumours in the large bowel.

Sulprostone, a synthetic PGE2 analogue in first trimester abortion. Clinical efficacy and influence on serum progesterone of different single doses

First trimester legal abortions were induced in 20 patients by i.m. injection of a single dose of 1,000, 1,200 or 1,500 micrograms of sulprostone. Complete expulsion of the conceptus within 24 h occurred in 16 of the women. There was a tendency to a higher rate of complete expulsion, as well as gastrointestinal side effects, at higher dosages. No association was found between the completeness of expulsion and the patients' serum progesterone levels before or after sulprostone injection.

Short-term maximal electrical stimulation--a conservative treatment of urinary incontinence

Seventeen women with stress and 20 with motor-urge urinary incontinence were treated ambulatorily with short-term maximal electrical stimulation. The duration of the treatment was 20 min daily for 12 weeks. According to the patients' subjective evaluation, two thirds were improved. A markedly diminished leakage of urine (greater than 50% by use of pad test) was found in 6 out of 17 women with stress, and in 13 out of 20 women with motor-urge urinary incontinence. There were no significant differences observed in urodynamic parameters between the registrations performed before and after the present electrical stimulation therapy.

The effect of cervical dilatation by laminaria tent in first trimester legal abortions on blood loss related to fibrinolytic activity in the decidua and placenta

Increased blood loss (BL) has been reported after cervical dilatation by laminaria tent in legal abortions. The BL was measured in 72 women in whom first trimester legal vacuum aspiration was performed. The cervical canal was dilatated by laminaria tent in 37 patients, and mechanically with Hegar dilators in 35 patients. BL was studied in relation to the plasminogen activators (u-PA, t-PA) and the plasminogen activator inhibitors (PAI-1, PAI-2) in the decidua and placenta. There was no significant difference in BL between the two groups. Decidual PAI-1 concentrations were significantly higher in the laminaria tent group than in the Hegar dilator group. An inactivation of u-PA by PAI-1 might explain the lack of increase in BL among the laminaria tent group.

Biochemical changes in human cervical connective tissue during pretreatment with laminaria tents in legal first trimester abortions

In 14 legal first trimester abortions, vacuum aspiration was preceded by dilatation of the cervical canal by laminaria tent for 16-20 h. Biopsy specimens obtained from the cervix before insertion and before removal of the laminaria tent were analyzed for biochemical changes in cervical connective tissue. Pretreatment with laminaria tents resulted in a decrease of the total collagen concentration and of the collagenolytic activity, though the differences were without statistical significance. Both these findings and those concerning the subfractions of the hydroxyproline concentration suggest that pretreatment with laminaria induces a certain degree of softening of the cervix, similar to that reported after intracervical application of PGE2 gel.

Placental and decidual u-PA, t-PA, PAI-1 and PAI-2 concentrations, as affected by cervical dilatation with laminaria tents or Hegar dilators

The effect of cervical dilatation on PA and PAI concentrations was compared in a laminaria tent group and a mechanical dilatation (control) group. In both groups, u-PA and t-PA were found to be present both in decidual and placental tissue. Values for PAI-1 in the decidua were higher in the laminaria tent group than in controls, and those for PAI-2 in the placenta were lower. These findings provide support for the contention that cervical dilatation with laminaria tents may result in partial detachment of the placenta.

Contractile activity in the human uterine cervix and corpus during cervical dilatation by laminaria tent in first trimester legal abortions

Millar microtransducers were used in 7 patients to record contractile variations in the cervix and corpus during dilatation of the cervical canal by Laminaria tent preceding first-trimester vacuum aspiration. The spontaneous contractile activity was registered in a control group of 5 patients without laminaria pretreatment. Two Millar catheters were used. The sensor tip of one Millar catheter was placed extra-amniotically in the uterine cavity, and the other one in the mid-cervical canal. Both sensor tips faced the wall of the cervix and corpus. The study showed that laminaria tents not only have a gentle dilatating effect on the cervix, but also induce painless uterine contractions, of amplitudes reaching 20 mmHg, and increased contractile activity in the cervix for the duration of dilatation.

Testing and training of the pelvic floor muscles after childbirth

In a prospective study of 83 women, two different physiotherapy methods for strengthening the pelvic floor muscles after childbirth were evaluated. The training program was carried out by the patients at home for 12 weeks, starting 8 weeks after spontaneous uneventful delivery. Forty-two women did pelvic floor exercises in accordance with the method presented by Kegel. Forty-one women used standard vaginal cones with weights increasing in 10 g stages from 20 to 100 g, to be retained in the vagina both when standing erect and moving. Pelvic floor muscle strength, defined as the weight in grams of the heaviest cone that could be retained in the vagina, was recorded before and after the 12-week training period. Training with vaginal cones produced significantly better pelvic floor muscle strength than did exercise without cones.

The influence of cervical dilatation by laminaria tent and with Hegar dilators on the intrauterine microflora and the rate of postabortal pelvic inflammatory disease

In a prospective study, 519 women were randomly selected for cervical dilatation by laminaria tents or Hegar dilators before scheduled vacuum aspiration. In other 68 women randomly divided into a laminaria group and a control (Hegar) group, placenta, decidua and blood were separately aspirated from the uterine cavity before the vacuum aspiration and cultured for micro-organisms. The rate of postabortal inflammatory disease (PID) was significantly lower after pretreatment with laminaria tent irrespective of patient's age and parity. However, a higher risk of postabortal PID was found in gestational age of 10-12 weeks than of 5-9 weeks. Previous PID and abortion did not increase the risk of postabortal PID. Vaginal/cervical micro-organisms were, irrespective of method for cervical dilatation, identified in two thirds of the patients.

Retropubic urethrocystopexy with fibrin sealant: a long-term follow-up

Transabdominal urethrocystopexy by using a two-component fibrin sealant as a substitute for sutures was performed in 99 women suffering from proved urinary stress incontinence. All were assessed preoperatively, both clinically and by urodynamic tests. This report deals with the results after a follow-up period not shorter than 1 year and up to 4 years. We found it essential not to report postoperative results concerning observation periods shorter than 1 year, as most relapses are observed more than 1 year after operation. Success was defined as absence of objective urine loss at coughing or straining with full bladder in upright position. The results imply that this simple technique is worthy of trial in correcting urinary stress incontinence in women.

Does the hygroscopic property of the laminaria tent imply a risk for ascending infection in legal abortions? A microbiological study

In 53 women admitted for first-trimester abortion, the cervical canal was dilated with laminaria tents prior to vacuum aspiration. Before insertion of the tents, endocervical specimens were taken for microbiological investigations, including Chlamydia trachomatis, and both aerobic and anaerobic microorganisms. The laminaria tents, widened by their hygroscopic properties, were removed just before the vacuum aspiration and sent for cultivation of aerobic and anaerobic microorganisms. The Gram-positive aerobic cocci, Staph. epidermidis, Strept. faecalis and Strept. agalactiae as well as Escherichia coli and Klebsiella/Enterobacter were the most frequent microorganism among the aerobic isolates from the endocervices as well as from the laminaria tents. These microorganisms were identified on the tents in greater numbers than in the cervices. Staph. aureus was isolated from three laminaria tents, but only one of these 3 women was proved to be primarily colonized endocervically. Among the anaerobes, Bacteroidaceae followed by peptococci and peptostreptococci were the predominant genera found in the cervix as well as on the removed laminaria tents. These three groups of anaerobic microorganisms were found markedly less frequently on the laminaria tents than in the endocervix. On the other hand, Strept. intermedius, another anaerobe of possible enteric origin, was recovered from 9 laminaria tents but not in the cervices. Since no cases of clinically verified endometritis/salpingitis were registered in the present study it is concluded that the risk of a pelvic inflammatory disease (PID) due to the laminaria tent is negligible as long as the laminaria treatment does not exceed 24 hours.

The effect of cervical dilatation by laminaria on the plasma levels of 15-keto-13,14-dihydro-PGF2 alpha

Laminaria tents were inserted to induce cervical dilatation prior to suction abortion in 42 primigravidae. The plasma level of 15-keto-13,14-dihydro-PGF2 alpha, the principal metabolite of prostaglandin F 2 alpha, increased during the dilatation period. The gentle dilatation by laminaria tents probably induces an endogenous synthesis of prostaglandins causing a softening of the cervix.
