Safety and efficacy of pimecrolimus cream 1% in the daily practice: Results of a patient self‐observation study in patients with atopic dermatitis

Background: Pimecrolimus cream 1% has proven to be well‐tolerated and effective in controlled clinical studies in patients with atopic dermatitis (AD). In a 15‐week patient self‐observation study, safety and efficacy was investigated in the daily practice. Patients and methods: 3502 patients with AD (mean age 26.2 ± 18 years, 62% female) received pimecrolimus cream 1% from 810 physicians in the German Federal Republic.The severity of the disease was assessed at baseline, two times during the 15‐week observation period and at the end of treatment.Patients recorded daily the degree of erythema and pruritus. At the end of treatment, safety and efficacy were assessed by the physician based on patient's daily records and by the patient. Results: The percentage of patients with severe or massive AD decreased from 25% to 7%, whereas the percentage of patients without or with mild symptoms increased from 9% to 55%.The efficacy of treatment was rated by physicians as good or very good in 83.5% of cases and by 79% of patients.At baseline 35% of the patients were free of flares as compared to 75% at the end of therapy. Disease control was better in patients who followed the recommended treatment algorithm for pimecrolimus cream.Tolerability was mostly rated as good or very good. Conclusion: Treatment with pimecrolimus cream 1% for patients with AD is well‐tolerated and effective in daily practice.     

The effect of subhypnotic doses of propofol on the incidence of pruritus after intrathecal morphine for Caesarean section

The effect of subhypnotic doses of propofol on intrathecal morphine-induced pruritus was studied in a prospective, randomly allocated, double-blind controlled trial. Fifty-eight women undergoing elective lower segment Caesarean section for a singleton fetus received spinal anaesthesia with 2.5 ml hyperbaric 0.5% bupivacaine and 0.2 mg of preservative-free morphine. They then received propofol 1 ml (10 mg) or Intralipid 1 ml (control group) intravenously after delivery. Pruritus was assessed using a five-point verbal rating scale at hourly intervals for 8 h. A second dose of their allocated treatment drug was administered at the first recording of significant pruritus. The pruritus score was reassessed after 5 min and the treatment was repeated if pruritus remained. There were no differences between the groups in the onset of pruritus or its successful treatment. No adverse side-effects were associated with this dose of propofol. There were no differences in the incidence of post-operative nausea and vomiting between the two groups. Subhypnotic propofol is not an effective treatment for intrathecal morphine-induced pruritus in women following Caesarean section.     

Recent advances in immunohistochemistry in gynaecological pathology

Recent years have witnessed significant developments in the use of immunohistochemistry in diagnostic gynaecological pathology. This review details the most significant of these. In ovarian pathology, differential cytokeratin staining (CK7 and 20) assists in distinguishing between a primary ovarian adenocarcinoma and a metastatic adenocarcinoma, especially of colorectal origin. The development of markers characteristic of ovarian sex cord-stromal tumours (especially alpha-inhibin) facilitates diagnosis of these neoplasms which is often difficult by morphology alone due to the wide differential diagnosis. In the uterus, the distinction between a primary endometrial and endocervical adenocarcinoma may be facilitated by use of a small panel of antibodies, including CEA, ER and vimentin. Newly developed antibodies such as CD10 and h-caldesmon may be of use in the diagnosis of uterine mesenchymal lesions, especially in the distinction between endometrial stromal and smooth muscle lesions. Proliferation markers, such as MIB1, are of value in the cervix in the diagnosis of preinvasive squamous and glandular lesions. Recent studies have shown that cervical adenoma malignum exhibits a gastric phenotype. Advances have also been made in trophoblastic disease with the development of antibodies reactive against trophoblast such as alpha-inhibin, mel-Cam and p57. A newly developed monoclonal antibody HMGIC which is expressed in vulvovaginal aggressive angiomyxoma may prove to be of value in the often difficult distinction of this lesion from its histological mimics.     

Angiomyofibroblastoma of the vulva: A mitotically active variant?

A case of angbmyofibrobiastoma in a 48-yearold woman is reported. The tumor occurred as a left vulval mass and was treated by simple excision. It was located in the subcutaneous tissue of the left vuiva and was well circumscribed, measuring 2.8 × 2.7 × 2.5 cm. Microscop Ically, the tumor was composed of hypocellular and cellular arees with well-developed small vessels. Spindle or polygonal cells were arranged with perlvascular accentuation In an edematous or fibrocollagenous background. Some spindle-shaped or polygonal stromal cells were also arranged in epithelioid nests. In some areas, mitosas were frequent (maximum 3/10 high-power field). lmmunohistochemicaily, the stromal cells were positive for vimentln and desmin, but negative for α-smooth muscle actin, S-100, neurofilament, estrogen receptor, progesterone remptor, CD31 and CD34. The average labeling index of Kl-67 In stromal cells was 3.1%. Ultrastructural analysis demonstrated that the stromal cells adhered with primitive Junctions and contained lntermediate filaments with no focal density In the cytoplasm. These findings were consistent with anglomyofibrobiastoma, although previously reported cases did not show so many mitoses. Therefore, this case was suggested to be a mitotically active variant.     

Angiomyofibroblastoma of the vulva: Case report with immunohistochemical, ultrastructural and DNA ploidy studies and a review of the literature

A case of anglomyofibroblastoma of the vulva in a 49-year-old woman was examined. The tumor measured 3×2.5×2 cm and appeared light gray to tan In color on the cut surface. Light microscopic examinations revealed that spindle or oval shaped tumor cells were arranged in loose edematous stroma with numerous thin-walled vessels. Ultrastructurally, cell organellae were not well developed but intracytoplasmic filaments of intermediate size were abundant in the tumor cells. Desmin, CD34 and vimentin immunoreactivity were detected in almost all of the tumor cells. Both estrogen and progesterone receptors were diffusely expressed In the tumor, suggestive of the sex sterold-dependency of this tumor. The Ki-67 labeling index was less than 1% and the DNA content of the tumor cells, which was examined by image cytometry, demonstrated diploidy (DNA index=0.97). These findings may reflect the quiescent or slow growing features of angiomyofibroblastoma.

Side effects during continuous epidural infusion of morphine and fentanyl

Respiratory effects, nausea, somnolence, and pruritus were compared during a 48-hr period of continuous epidural morphine (n = 34) and fentanyl (n = 32) infusion in 66 patients following elective total replacement of the hip or knee joint. Respiratory effects were assessed by PaCO2. Side effects were assessed by visual analogue scale and considered to be present when the score was above 30. Assessment was made at preoperative visits then 3, 6, 12, 24, 36, and 48 hr after the epidural injection. The bolus dose and subsequent infusion rate were 3,900 +/- 1,300 micrograms and 427 +/- 213 micrograms.hr-1 for morphine, and 85 +/- 46 micrograms and 56 +/- 27 micrograms.hr-1 for fentanyl. Pain relief was similar in both groups. In the morphine group, PaCO2 elevation and nausea occurred over a period of more than 12 hr (P less than 0.05). In the fentanyl group, there was no PaCO2 change, and nausea was confined to the first few hours. Nausea was more severe (P less than 0.01 at six hours and more frequent (24 hr cumulative incidence, 53 vs 28%, P less than 0.05) in the morphine group. Somnolence was prominent within several hours in two-thirds of patients in both groups. Somnolence continued to decline thereafter in the morphine group, but it was demonstrable in approximately half of the patients throughout the second day in the fentanyl group. The incidence was higher in the fentanyl group at the 48th hr (P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
