B-N-acetyl hexosaminidase (B-NAH) serum levels after endotoxin administration into the portal vein in the rat.

Endotoxin was injected directly into the portal vein in rats with and without common bile duct (CBD) ligation. B-N-acetyl hexosaminidase (B-NAH) activity levels in the serum were found to be significantly elevated 24 h later in both groups. Serum bile acid levels were found to be significantly higher in the endotoxin-injected groups of rats compared to controls. Thus, endotoxin, as well as bile acids, may cause damage to Kupffer cell membranes, resulting in accumulation of B-NAH in rat serum.

Iatrogenic injuries to the ureter during gynecologic and obstetric operations.

Iatrogenic injuries to the ureter are hazardous complications of pelvic and vaginal operations, causing severe morbidity and even mortality. Eighteen such instances that occurred during the last 30 years are analyzed. Most of the injuries were associated with attempts to achieve hemostasis without proper identification of the ureter. The incidence of ureteral injuries declined during the years concomitantly with the improvement of surgical techniques. The proper identification and, when necessary, isolation of the ureter during operations in which there is a risk is crucial in reducing the incidence of ureteral injuries. Those diagnosed at the time of injury and treated with end to end anastomosis had the best results. Delayed diagnosis and treatment were associated with poor end results. The English literature is reviewed.

The effect of large uterine fibroids on urinary bladder function and symptoms.

Fourteen patients with large uterine fibroids and urinary symptoms were treated with monthly injections of [D-Trp6]-luteinizing hormone-releasing hormone microcapsules. The average uterine size before treatment was 728 ml; it dropped to 323 ml (a drop of 55%) after treatment. Urinary symptoms of diurnal frequency disappeared in 11 of 12 patients (p less than 0.005) after the reduction of uterine size. Urgency decreased in 11 of 13 (p less than 0.005) and nocturia in eight of 10 (p less than 0.02). No differences were found before and after treatment in the symptoms of urge incontinence and stress incontinence in the cystometric and urethral pressure profile measurements. Urinary symptoms of frequency, urgency, and nocturia may be caused by the direct pressure exerted on the bladder by the enlarged uterus. Symptoms of urge incontinence and stress incontinence deserve a more specific treatment as they are not related to uterine size.

Hormonal changes related to impairment of cervical mucus in cycles stimulated by clomiphene citrate.

The levels of luteinizing hormone (LH), follicular stimulating hormone (FSH), 17-oestradiol (E2), progesterone (P), and testosterone (T) were determined for the early, midfollicular and periovulatory phase of spontaneous and clomiphene citrate (CC) induced cycles in 5 patients who responded with appearance of hostile cervical mucus (Group A) and 5 patients whose cervical mucus remained unchanged during the same treatment (Group B). The patients with hostile mucus were further investigated during a third cycle stimulated by CC and ethinyloestradiol (EE). Patients treated with CC for induction of ovulation who developed hostile cervical mucus showed higher levels of LH and T in the midfollicular phase of the menstrual cycle and significantly higher levels of T in the periovulatory period compared to patients with unchanged mucus. EE treatment induced a drop in the elevated LH and T levels and improved the cervical score. No change in E2 levels was noted. A direct effect of EE on the cervical glands together with the centrally mediated lowering of serum T are suggested to be responsible for improving the cervical mucus.

Inflammatory bowel disease and serum beta-N-acetylhexosaminidase.

Serum beta-N-acetylhexosaminidase levels in 49 patients with inflammatory bowel disease (IBD; 23 patients with ulcerative colitis, 10 with Crohn's disease, and 16 with ileostomy after total proctocolectomy) as well as in healthy normal controls were determined. They were found to be significantly elevated in 91% of all patients, disregarding the state of activity of the disease. It seems most likely that activated macrophages are the source of this lysosomal hydrolase in the serum of IBD patients since other theoretical possibilities, like damaged hepatocytes or elevated serum bile acid levels, are not relevant for these patients.

Penicillin-tetracycline prophylaxis in cesarean delivery: prospective and randomized comparison of short and long term therapy.

A prospective and randomized study was undertaken to determine the safety and efficacy of low price and discouraging bacterial resistance agents, given for 12 hours versus 72 hours, as prophylaxis at cesarean section. Ninety six patients received penicillin (ten million units) intravenously and tetracycline (0.25 g) intramuscularly at cord clamping and 12 hours postoperatively (table I). Among them 14% of febrile morbidity was recorded (table II). Eighty seven patients received the same treatment followed by oral ampicillin (2 g) and tetracycline (1.5 g) per day, for a further 60 hours (table I). Maternal febrile morbidity was not further reduced by the oral additional treatment (table II). This regiment prophylactic effect is comparable to previous reported data concerning other protocols, and even better, while expenses are reduced and efficacy for important pathogens such as chlamydia and mycoplasma is obtained. No side effects of the drugs were recorded.

Serum-beta-N-acetyl hexosaminidase (beta-NAH) in the elderly.

Serum levels of beta-N-Acetyl Hexosaminidase (beta-NAH) provide information on the normal non-phagocytic function of Kupffer cells in the liver. Beta-NAH can thus be used as an indicator for non-parenchymal non-phagocytic liver cell function, whereas most of the more routine liver function tests measure hepatocytic status or function. Serum beta-NAH activity levels found in 49 patients and 10 healthy individuals above the age of 65 did not differ significantly from those found in younger controls. The results clearly indicate that beta-NAH serum activity in the aged is within normal limits and, if accepted as a routine measure of the non-phagocytic function of non-parenchymal liver cells, could be used in all adults.

Colposuspension for urinary stress incontinence in premenopausal and postmenopausal women.

Sixty-nine premenopausal and 53 postmenopausal women had a colposuspension operation for urinary stress incontinence. A significant postoperative reduction (p less than 0.001) of symptoms of frequency, nocturia, urgency and urge incontinence was obtained in both groups. Postoperatively, 88.4 per cent of the premenopausal women were found to be dry compared with 66 per cent in the postmenopausal group (p less than 0.01). No differences were found preoperatively and postoperatively in the cystometric values or in the urethral pressure profiles at rest in both groups and between the groups. The pressure transmission ratios were significantly improved postoperatively in both groups. The postoperative transmission ratios in the premenopausal women were found to be significantly higher than those in the postmenopausal group, at the middle two-quarters of the urethra. Although surgical treatment for urinary stress incontinence in postmenopausal women results in lower cure rates than in younger women, it should be considered.

The effect of total abdominal hysterectomy on bladder function in asymptomatic women.

The effect of total abdominal hysterectomy as treatment for benign conditions on the postoperative incidence of urinary symptoms and abnormal urodynamic findings was evaluated in 16 premenopausal women who lacked urinary symptoms preoperatively. The urodynamic evaluation was performed preoperatively, at 4 weeks, and again at 4 months after surgery. No clinical symptoms of frequency, nocturia, urgency, or urge or stress incontinence were found postoperatively. There were no significant differences from the preoperative values for cystometry, uroflometry, and urethral pressure profiles. Urinary dysfunction should not be a consequence of an uncomplicated total abdominal hysterectomy for benign conditions in women who were previously free of urinary symptoms.

Acute intermittent porphyria in pregnancy.

A 27-year-old, previously healthy normotensive woman was admitted for hyperemesis gravidarum and treated with intravenous fluids and metoclopramide. Thereafter, a neuropsychiatric syndrome developed, with acute asymmetrical axonal motor-sensory polyneuropathy and marked anxiety, depression, irritability, and memory and concentration difficulties. Raised porphyrin precursors were found in the patient's urine, but not in her feces. Although the association of acute porphyria and pregnancy is rare, the pregnancy itself, combined with a state of starvation, and the administration of metoclopramide, could have precipitated the acute attack in this case. Thiamine deficiency, Guillain-Barré syndrome, and an obstetric complication producing closely related symptoms were excluded. The drug was stopped and the patient was treated with a high-carbohydrate diet and physiotherapy. A normal infant was delivered spontaneously at term.

A new group of defibrillatory drugs in the classification of antiarrhythmic agents.

Ventricular antiarrhythmic therapy is aimed traditionally at preventing arrhythmias and ventricular fibrillation. Recently, a new approach has been introduced, where drug therapy facilitates the ability of the heart for spontaneous defibrillation. The chemical features and the electrophysiologic properties are discussed below. The introduction of this new group of defibrillating antiarrhythmic drugs implies the extension of the common classification of antiarrhythmic drugs.

The value of simultaneous hysterectomy during Burch colposuspension for urinary stress incontinence.

The effect of concomitant hysterectomy during colposuspension on the cure rate of genuine stress incontinence was evaluated prospectively in 45 patients. Twenty-two women underwent a colposuspension only (no-hysterectomy group) and 23 had a concomitant abdominal hysterectomy and cul-de-sac obliteration (hysterectomy group). Twenty-five months postoperatively, no differences were found in the cure rate for urinary stress incontinence between the two groups (95.5 and 95.7% for the no-hysterectomy and the hysterectomy group, respectively). In the no-hysterectomy group, three patients (13.6%) had enterocele formation after surgery; this complication did not occur in any of the patients in the hysterectomy group.
