ABSTRACT
CR-39 tracketch detectors were used for the measurement of (222)Rn concentration in 24 offices in Nigeria's oldest university campus in order to estimate the effective dose to the occupants from (222)Rn and its progeny. The dosimetric measurements were made over a period of 3 months. Questionnaires were distributed and analyzed. The radon concentration ranged from 157 to 495 Bq/m(3), with an arithmetic mean and standard deviation of 293.3 and 79.6 Bq/ m(3), respectively. The effective dose to the workers was estimated and this varied from 0.99 to 3.12 mSv/ y, with a mean of 1.85 mSv/y. The radon concentrations were found to be within the reference levels of ICRP.
ABSTRACT
OBJECTIVE: To explore drug (prescription, over-the-counter and herbal) utilization in pregnant women attending a public sector tertiary healthcare institution. METHODS: This was a cross-sectional case study in women attending antenatal clinics at the Mount Hope Women's Hospital. Women (506) who consecutively presented for routine care at the antenatal clinic were interviewed on the medication they took. Descriptive statistics and logistic regression for predictors of drug use were done using SPSS 16. RESULTS: There were 200 (39.5%) primigravidae, 306 (60.5%) multigravidae and 299 (59%) women were in the third trimester of pregnancy. Most women (69.8%) were between 20-35 years of age. Women took an average of 1.32, 1.22 and 0.94 prescribed drugs in each trimester, respectively. Multivitamins (59.8%) and iron/folic acid (54.2%) were the most frequently prescribed drugs. Regardless of trimester, only 20% of women took supplemental calcium. Very few women (2.4%) took herbal medications. Paracetamol was the most common over-the-counter (OTC) medication in all trimesters. Women with secondary level education were most likely to use OTC iron/folic acid (p = 0.02), paracetamol and histamine2 receptor antagonists [H2RAs] (p = 0.001). More primigravidae took non-steroidal anti-inflammatory drugs (p = 0.02) and more women in the first trimester used antiemetics (p = 0.001). Age group (p = 0.048), marital status (p = 0.001) and the trimester of pregnancy (p = 0.001) were predictors of drug utilization. CONCLUSION: Overall, women in tertiary healthcare institutions took medication as prescribed particularly multivitamins and iron/folic acid. More women with higher education took OTC paracetamol, iron/folic acid and vitamin supplements. Herbal supplements were rarely used. Research on drug utilization in primary care facilities is recommended.
OBJETIVO: Explorar el uso de los medicamentos (con prescripción, sin receta médica, herbarios) en mujeres embarazadas que asisten a una institución terciaria de atención a la salud pública dentro del sector público. MÉTODOS: Se trató de un estudio transversal de mujeres que asisten a las clínicas prenatales en el Hospital de Mujeres Mount Hope. Las mujeres (506) que consecutivamente se presentaron para cuidados de rutina en la clínica prenatal, fueron entrevistadas acerca de la medicación que tomaban. Se hicieron estadísticas descriptivas y se hizo una regresión logística para los predictores del uso del medicamento usando SPSS 16. RESULTADOS: Había 200 (39.5%) primerizas, 306 (60.5%) multíparas, y 299 (59%) embarazadas en su tercer trimestre. La mayoría de las mujeres (69.8%) tenían entre 20-35 años de edad. Las mujeres tomaban un promedio de 1.32, 1.22 y 0.94 medicamentos prescritos en cada trimestre, respectivamente. Las multivitaminas (59.8%) y el hierro/ácido fólico (54.2%) fueron los medicamentos más frecuentemente prescritos. Con independencia del trimestre, sólo 20% de las mujeres tomaron suplemento de calcio. Muy pocas mujeres (2.4%) tomaban medicaciones herbarias. El paracetamol fue el medicamento sin receta más común en todos los trimestres. Las mujeres con nivel de educación secundaria presentaban una mayor probabilidad de usar hierro/ácido fólico (p = 0.02), el paracetamol y los antagonistas de los receptores de la histamina-2- [H2RAs] (p = 0.001). Un mayor número de primerizas tomaron medicamentos anti-inflamatorios no esteroideos (p = 0.02) y más mujeres en el primer trimestre usaron anti-eméticos (p = 0.001). El grupo etario (p = 0.048), el estado matrimonial (p = 0.001) y el trimestre de embarazo (p = 0.001) fueron predictores de la utilización de medicamentos. CONCLUSIÓN: En general, las mujeres en las instituciones terciarias de atención a la salud tomaron la medicación como fue prescrita, en particular las multivitaminas y el hierro/ácido fólico. Más mujeres con mayor escolaridad tomaron medicamentos sin recetas: paracetamol, hierro/ácido fólico y suplementos de vitamina. Raramente se usaron suplementos herbarios. Se recomienda la investigación del uso de medicamentos en centros de atención primaria.

Psoriatic plaque skin incubated for eight days in organ culture in the presence of a potent epidermal growth factor (EGF) receptor tyrosine kinase (RTK) antagonist reverted to a more normal histological appearance, while untreated psoriatic plaque skin retained histological features associated with the psoriatic phenotype. In concomitant studies it was shown that the EGF-RTK antagonist had no significant effect on histological features of non-psoriatic skin and no effect on dermal function, i.e. elaboration of both type I procollagen and matrix metalloproteinase-1 (MMP-1; interstitial collagenase). When human epidermal keratinocytes were treated with the EGF-RTK antagonist in monolayer culture, growth inhibition was seen (ED(50) = approximately 0.06 microM). When dermal fibroblasts were exposed to the EGF-RTK antagonist in monolayer culture, proliferation, MMP-1 and type I procollagen production were essentially unaffected at concentrations which interfered with keratinocyte growth (up to 1 microM). The capacity of the EGF-RTK antagonist to modulate the histological features of psoriatic skin in organ culture under conditions in which normal skin architecture and dermal function are largely unaffected suggests a potential for anti-psoriatic therapy.
