Use of audiotaped patient consultations in a head and neck oncology clinic and survey of patient attitudes to this facility

The overall quality and delivery of patient care is becoming increasingly important, especially in those diagnosed with cancer. Multidisciplinary clinics are a valuable adjunct to this, but patients may not fully understand or comprehend all that is said to them. The use of audiotaping consultations has been studied in some settings, but not in head and neck cancer clinics. We report on a series of 50 consecutive head and neck patients to determine their views on the value of this facility. Thirty-nine patients (78 per cent) utilized the opportunity, of which 36 patients (92 per cent) found it beneficial. Over three quarters of the patients who used the facility thought that medical staff could benefit and learn from the tape recording. We recommend that audiotaping becomes a standard part of the multidisciplinary head and neck oncology clinic, helping to improve the overall quality of patient care.     

Maternal serum interleukin-6, interleukin-8, tumor necrosis factor-alpha and interferon-gamma in preterm labor

BACKGROUND: To find out whether preterm labor is associated with raised maternal serum concentrations of interleukin (IL)-6, IL-8, tumor necrosis factor alpha (TNF-alpha) and interferon gamma (IFN-gamma) and whether the measurement of these cytokines can be used to detect early intrauterine infection in preterm labor. METHODS: Cross-sectional study: 77 women in preterm labor, 47 controls of healthy preterm women not in labor and 19 women in term labor. The serum cytokines levels were measured by enzyme-linked immunosorbent assay (ELISA). The newborns of women who were in labor were followed up for evidence of infection. Differences between groups were tested using analysis of variance, Student's t-test and chi2-test. RESULTS: There was no significant difference in the concentration of all the cytokines measured between the different groups. No statistical difference was found in the concentration of the cytokines between women in preterm labor with ruptured membranes and those with intact membranes. There was also no difference found in the concentration of cytokines between women whose newborns had positive bacterial culture and those with negative culture. There was a positive correlation between the concentrations of IL-6, IL-8 and TNF-alpha. CONCLUSION: Serum levels of interleukin-6, interleukin-8 and tumor necrosis factor-alpha were not increased in preterm labor compared to normal control women. There is doubt regarding the usefulness of maternal serum measurement of these cytokines for the detection of early fetal infection in preterm labor, but this needs further evaluation.     

Decreased expression of tissue inhibitor of matrix metalloproteinases in follicular fluid from women with polycystic ovaries compared with normally ovulating patients undergoing in vitro fertilization

OBJECTIVE: To compare activity of matrix metalloproteinases (MMP) and expression of their tissue-specific inhibitor (TIMP) in the follicular fluid of normally ovulating women and women with the polycystic ovary syndrome (PCOS). DESIGN: Prospective study. SETTING: IVF unit and endocrine research unit. PATIENT(S): Fourteen patients undergoing IVF treatment (seven with normal ovulation and seven with PCOS). MAIN OUTCOME MEASURE(S): Activity of MMP-2 and MMP-9 and expression of MMP-1, TIMP-1, and TIMP-2 was measured in follicular fluid of the leading follicles by using gel zymography and immunoblot analysis. RESULT(S): The activity of MMP-2 and MMP-9 and expression of MMP-1 was similar in follicular fluid of normally ovulating patients and patients with PCOS. Significantly lower expression of TIMP-1 was found in follicular fluid of patients with PCOS women compared with normally ovulating patients. CONCLUSION(S): Because MMPs and TIMPs play a role in the physical and chemical structure of the follicular compartment, the decreased expression of TIMP in patients with PCOS may be part of a compensatory process to overcome the physical properties of the thick ovarian capsule.     

Spontaneous regression of patient omphalomesenteric duct: from a fistula to Meckel's diverticulum.

A newborn with a patent omphalomesenteric duct is described in this report. This anomaly is a very rare one. Regression of the omphalomesenteric duct occurs as a normal embryonic event in the intrauterine life between the fifth and ninth week of gestation; however, in this case regression occurred spontaneously in the neonatal period and resulted in a Meckel's diverticulum with no connection with the umbilicus. This is the first case to be reported.     

Selective agonists and antagonists to thyroid hormone action.

Selective thyromimetics have been designed and shown to exhibit some of the beneficial effects of thyroid hormones, such as lowering of cholesterol and weight reduction, without the adverse thyroid hormone action on muscle, bone, and heart rate. Progress has also been made in attempting to treat hyperthyroidism by synthesizing antagonists that block thyroid hormone action, at the level of the thyroid hormone receptor or of the thyrotropin receptor. Clinical trials are still awaited, however, to verify whether these potentially promising agents will indeed prove to be of clinical therapeutic value.     

Estimates of the prevalence of childhood seizure disorders in communities where professional resources are scarce: results from Bangladesh, Jamaica and Pakistan

Although numerous estimates of the prevalence of seizure disorders in populations in the less developed world have now been published, these estimates are difficult to interpret due to lack of comparability of study methods and criteria for case definition. The results reported in this paper are from a large, collaborative study of disabilities in 2- to 9-year-old children in which standard research procedures and case definitions were used in three diverse populations (located in Bangladesh, Jamaica and Pakistan). A two-phase study design (screening followed by professional evaluations) was used in this study allowing for the professional evaluation to serve as the criterion in the estimation of prevalence, even for rare disorders. As a result, the prevalence estimates reported here have a high degree of comparability across populations and exhibit unusually strong validity for population surveys. Febrile seizures were the most common type of seizure history in all three populations, with point estimates of lifetime prevalence ranging from 10.9 to 62.8 per 1000. The lifetime prevalence rates of epilepsy (recurrent unprovoked seizures) ranged from 5.8 to 15.5 per 1000. Lifetime prevalence rates of neonatal, all provoked and all unprovoked seizures, as well as estimates of the prevalence of active epilepsy, are also reported.
