Paracervical anesthesia for outpatient hysteroscopy.

One hundred seventy-seven women aged 41 +/- 8 (mean +/- SD) years, referred for evaluation of excessive uterine bleeding, were enrolled in an open-label randomized trial to evaluate the efficacy of local anesthesia before hysteroscopy in an outpatient population. The patients underwent hysteroscopy and endometrial biopsy with paracervical block by 10 mL of 1% mepivacaine hydrochloride solution (n = 87) or no local anesthesia (n = 90) and assessed lower abdominal and pelvic pain according to a 10-point linear analog scale. The mean +/- SD pain score was 4.5 +/- 2.0 at hysteroscopy and 5.2 +/- 2.1 at endometrial biopsy in the 87 subjects given a paracervical block versus 4.9 +/- 2.2 and 5.7 +/- 2.4 in the 90 women not given local anesthesia, without statistically significant differences. Paracervical anesthesia for routine outpatient hysteroscopy in premenopausal women may be superfluous.

Pregnancy at forty and over: a case-control study.

We compared obstetric prognosis in 327 women > or = 40 years old (148 nulliparas, 279 multiparas) with 20-30-year-old matched controls who delivered at our department between 1988 and 1990. Gestational diabetes and chronic hypertension were the only more frequent antepartum complications in cases than controls (2.4% vs. 0.3% and 3.4% vs. 0.3%, respectively). There were more premature deliveries in cases than controls (19% vs. 8%) but no difference in postdate deliveries. Cesarean section was more frequent in cases than controls in both nulliparas (64% vs. 30%) and multiparas (43% vs. 12%). Incidence of abdominal delivery for acute obstetrical indications was not increased in older gravidas. Significant differences were observed in low birthweight (17% vs. 5%) and 5-min Apgar score < 7 (8% vs. 2%). Most of the abnormal Apgar scores were recorded after cesarean section; values for vaginally-delivered infants were comparable in older and younger women. Perinatal mortality was similar in the two groups.

Does contraception modify the risk of endometriosis?

Long episodes of regular, prolonged, abundant menstrual flows are generally agreed to increase the risk of endometriosis. Since oral oestrogen-progestogen combinations reduce and intra-uterine contraceptive devices increase menstrual flow, an effect on the risk of development of endometriosis in women utilizing these forms of contraception could be expected. Analysis of the most recent epidemiological observations shows no consensus on a possible relationship between use of cyclic oral contraceptives and endometriosis, with an increase, a decrease, and no effect on the risk of developing the disease all being reported. A lower relative risk of endometriosis in previous users of the intrauterine contraceptive device was only found in two series, most of the other data suggesting a rise in risk or no effect. Further studies on the relationship between type of contraception and endometriosis are needed to demonstrate whether the risk of development of the disease could be influenced, and whether well tolerated, relatively inexpensive, long-term treatment might be available for symptomatic patients not desiring offspring.

Adenomyosis: a déjà vu?

Adenomyosis is a relatively frequent finding in series of hysterectomies performed for menorrhagia and dysmenorrhea. Evident selection biases of the available studies on adenomyosis have always limited the possibilities of defining the real clinical importance of the condition. Until now the only certain diagnoses have been made by histopathologists on uteri removed at surgery, but recently various sufficiently accurate techniques have been suggested which allow diagnosis on the uterus in situ. With the these methods it might be possible to obtain correct information on the epidemiologic characteristics of adenomyosis and to clarify whether it has a pathogenic role in unexplained ovulatory menorrhagia and juvenile dysmenorrhea. Furthermore, resectoscopic treatment has been proposed in some mild forms of adenomyosis to avoid hysterectomy, whereas it seems improbable that medical treatment can offer a definitive solution. The adoption of standard histologic criteria for adenomyosis seems important. Until this is done, it will be difficult to establish whether adenomyosis is really a disease or merely a paraphysiologic condition.

Abnormal uterine bleeding associated with iron-deficiency anemia. Etiology and role of hysteroscopy.

We reviewed the clinical and histologic records of 61 consecutive premenopausal women with abnormal uterine bleeding and moderate to severe iron-deficiency anemia investigated in a tertiary care and referral center. Excessive bleeding was caused by benign lesions in 67% of the cases and by anovulation in 25% and was unexplained in 8%. Hysteroscopy revealed an organic intrauterine lesion (submucous myomas in 38%, endometrial polyps in 13%, submucous adenomyomas in 3%) that could be treated endoscopically in more than half the patients. In populations without nutritional deficiencies, a woman of reproductive age with sideropenic anemia and no other evident cause of blood loss or systemic disease should be considered menorrhagic until proven otherwise. Hysteroscopy should be included in evaluations of abnormal uterine bleeding.

A multicenter, prospective study of posttransfusion hepatitis in Milan.

We studied the risk of posttransfusion hepatitis in recipients of blood collected from volunteer donors who tested negative for HBsAg and had serum ALT levels less than 1.5 times the upper limit of the normal range. Between October, 1983 and September, 1984, 676 consecutive patients who needed blood or plasma transfusions during or after elective surgery, who had no history of liver disease and had never received blood previously, were studied. The patients were given a total of 4,813 (mean = 7) units. Ninety-six patients developed posttransfusion hepatitis, which yielded a hepatic incidence of 20 cases per 1,000 units of transfused blood. Ninety-two patients had non-A, non-B hepatitis, 3 had hepatitis B and 1 had cytomegalovirus infection. The incubation periods for non-A, non-B hepatitis ranged from 2 to 26 (mean = 9.5 +/- 4) weeks. In 68 (73%) patients, the hepatitis was completely asymptomatic; only 24 (27%) patients developed symptoms, including jaundice and hepatomegaly. There were no cases of fulminant hepatitis. Sixty per cent of the patients still had elevated serum ALT levels 1 year after the onset of hepatitis. The 96 patients with hepatitis had received a mean of 9.6 blood units, as compared to a mean of 6.7 units for the unaffected patients (p less than 0.001). This study demonstrated that non-A, non-B hepatitis remains a common and important complication of blood transfusion despite screening of blood donors for HBsAg and elevated serum ALT levels.

Preoperative CEA, NSE, SCC, TPA and CYFRA 21.1 serum levels as prognostic indicators in resected non-small cell lung cancer.

In 62 patients affected by resectable non-small cell lung cancer (NSCLC) submitted to radical surgery we evaluated the prognostic significance of CEA, NSE, SCC, TPA, and CYFRA 21.1 serum levels at diagnosis, as well as the predictive ability of these tumor markers with respect to histological type and pathological stage. The group was composed of 56 male and 6 female patients; the median age was 62 years (range 29-73 years). Thirty-four patients had a histological diagnosis of adenocarcinoma and 28 of squamous cell carcinoma; with regard to pathological stage, 32 patients had stage 1, 4 patients stage II and 23 patients stage IIIA disease. A good predictive ability with respect to histological type was obtained with SCC serum levels; as for pathological stage, TPA and CYFRA 21.1 were found to have moderate predictive ability. In this series of patients, at a median follow-up of 55 months after surgery, we found that both TPA and CYFRA 21.1 serum levels at diagnosis were reliable predictors of overall survival, high values of these markers being associated with a worse prognosis.

[Sepsis, acute renal failure and multiple organ dysfunction syndrome].

The so-called systemic inflammatory response syndrome (SIRS ) represents the cellular inflammatory and neuroendocrine systemic reaction in response to many adverse events. epsis is defined as IR induced by bacterial, mycotic or viral toxins. The circulating toxins deriving from the bacterial wall can activate the septic cascade that induces many systemic reactions involving the activation of the cellular immunity, complement and coagulation system. The endothelial cell is the target of the systemic phlogistic reaction; its stimulation is followed by the production of many vasoactive paracrine and systemic agents. In this context, local and systemic cytokine production plays a major role in inducing the septic cascade, which although meant to be a phlogistic defense reaction, can often become an uncontrolled and dangerous inflammatory reaction. The sepsis-derived lesions can involve many organs and apparatus leading to the picture of sepsis syndrome. Sepsis syndrome often induces severe pulmonary lesions with a picture of acute respiratory distress syndrome (ARDS ). The combination of acute renal failure and sepsis is associated with a high mortality rate, namely in patients with a nitric oxide-induced systemic reduction in peripheral vascular resistances and septic shock. The toxinemia can also induce myocardial damage with a reduction in cardiac performance. Therefore, septic patients who have a combination of pulmonary, cardio-vascular, renal and cerebral lesions present with the picture of multiple organ dysfunction syndrome, that can increase mor-tality to > 0%.
