Predictive values of ultrasound-based scoring system in morbidly adherent placenta for high risk group
Background: The objective of the present study was to find out the predictive values of an ultrasound-based scoring system in diagnosis of morbidly adherent placenta (MAP) for high risk group. Obstetrics and Gynecology Department, Faculty of Medicine, South Valley University, Egypt.Methods: 63 full term pregnant women (≥37 weeks of gestation) with high risk of morbidly adherent placenta underwent elective cesarean section. Placental assessment by 2 D ultrasound based on ultrasound scoring system in morbidly adherent placenta, these data were recorded for further comparison with intraoperative data for degree of placental adherence.Results: Incidence of MAP was 7.93% (4.76% had a focal form and 3.17% had a complete form of accreta). As regarding to scoring system, 82.5 of cases had a low risk (< 5), 9.5% had a moderate risk (6-7) and 7.93% had a high risk (8-12) of development of morbidly adherent placenta with p value <0.0001. The sensitivity, specificity, positive and negative predictive values of the US scoring system for morbidly adherent placenta were (92.3%, 94.1%, 87.453% and 98.2%) respectively.Conclusions: Ultrasound based scoring system had a high predictive value (sensitivity, specificity, positive and negative predictive values) in diagnosis of morbidly adherent placenta for pregnant women have any risk factors for developing MAP
Expression of cyclooxygenase-2 and 12-lipoxygenase in human breast cancer and their relationship with HER-2/neu and hormonal receptors: Impact on prognosis and therapy
Background: A number of studies have shown over-expression of cox-2 in
breast cancer. Also it has been recorded that human breast cancer
expresses high level of cox-2 and 12-lipoxygenase which may be
beneficial in future therapy plan for those patients. Aims: The
present study aims to examine the level of transcripts of cox-2 and
12-lipoxygenase in Egyptian breast cancer patients and to compare
between the expressions of both enzymes and TNM staging, hormone
receptors status (including estrogen and progesterone) and HER2/neu
expression. Materials and Methods: Total cellular RNA was extracted
from 64 frozen tissue samples of breast carcinoma and their
corresponding normal adjacent tissues. Cox-2 and 12-lipooxygenase
expressions were detected using RT-PCR. Hormonal receptors as well as
HER2/neu were detected immuno-histochemically for each patient.
Results: About 47 and 62.5% of carcinoma samples showed
over-expression of cox-2 and 12-lipooxygenase respectively as compared
to their corresponding normal tissues. The results revealed that cox-2
significantly associated with TNM staging ( P =0.0047) and hormonal
receptors status ( P = 0.0201). The relationship between cox-2 and
HER2/neu expression was close to a significant value ( P =0.0747).
12-lipooxygenase showed only significant association with TNM staging (
P =0.0076). Neither hormonal receptors nor HER2/neu showed significant
association with this enzyme. Conclusion: Elevated levels of cox-2
and 12-lipoxygenase expression were detected in human breast cancer.
Also, the results revealed that cox-2 and 12-lipooxygenase mRNA
expressions are associated with TNM staging in human breast cancer.
Furthermore, there is an inverse association between cox-2 expression
and hormonal receptor status. This observation may drive us to the
possible role of those two enzymes in determining the plan of therapy
of breast cancer patients
Prevalence of Helicobacter Pylori Infection in Pregnant Women with Hyperemesis Gravidarum
Background: Hyperemesis gravidarum (HG) is a severe form of vomiting that occurs in 0.3-2% of all pregnant women. There is geographic difference in the prevalence of Helicobacter Pylori (H. Pylori). The exact prevalence in Egypt is not well-studied.
Objectives: To detect prevalence and risk factors for H. Pylori in pregnant women with HG.
Patients and Methods: This was a cross-sectional study. The study was conducted at the Department of Obstetrics and Gynecology, South Valley University hospitals.
Results: The study included 100 pregnant women with HG.In this study, the H. Pylori stool antigen testing was positive in 44 cases out of 100 cases, making a prevalence of 44%. Risk factors of H. Pylori was rural residence (adjusted OR: 3.45; CI:1.12-10.94; and P value: 0.03), recurrence of vomiting in the current pregnancy (adjusted OR was 3.85; CI:1.15-12.91; and P value: 0.03), and anemia (adjusted OR: 0.74; CI: 0.55-0.98; and P value: 0.04)
Conclusion: H. Pylori affects 44% of women with HG. There was significant association between H. pylori and the rural residence, the recurrence of vomiting in the same pregnancy, and the presence of anemia
Expression of cyclooxygenase-2 and 12-lipoxygenase in human breast cancer and their relationship with HER-2/neu and hormonal receptors: Impact on prognosis and therapy
A case of limbic encephalitis presenting as a paraneoplastic manifestation of limited stage small cell lung cancer: a case report
<p>Abstract</p> <p>Introduction</p> <p>The differential diagnosis of altered mental status and behavioral change is very extensive. Paraneoplastic limbic encephalitis is a rare cause of cognitive impairment, which should be considered in the differential diagnosis.</p> <p>Case presentation</p> <p>A 64-year-old British Caucasian woman presented to our hospital with a 12-week history of confusion and short-term memory loss. She was hyponatremic with a serum sodium level of 128mmol/L. Moreover, there was evidence of left hilar prominence on the chest radiograph. A thoracic computed tomography scan showed left hilar opacity with confluent lymphadenopathy. A percutaneous biopsy confirmed a diagnosis of small cell lung cancer. There was no radiological evidence of brain metastasis on the computed tomography scan. In view of continued cognitive impairment, which was felt to be disproportionate to hyponatremia, a magnetic resonance imaging scan of the brain was undertaken. It showed hyperintense signals from both hippocampi, highly suggestive of limbic encephalitis presenting as a paraneoplastic manifestation of small cell lung cancer. She had a significant radiological and clinical response following chemotherapy and radiotherapy.</p> <p>Conclusion</p> <p>This case highlights the importance of considering paraneoplastic syndromes in patients with neurological symptoms in the context of lung malignancy. If initial investigations fail to reveal the cause of cognitive impairment in a patient with malignancy, magnetic resonance imaging may be invaluable in the diagnosis of limbic encephalitis. The clinical presentation, diagnostic techniques and management of paraneoplastic limbic encephalitis are discussed in this case report.</p
Chiral Dynamics in Photo-Pion Physics: Theory, Experiment, and Future Studies at the HIS Facility
A review of photo-pion experiments on the nucleon in the near threshold
region is presented. Comparisons of the results are made with the predictions
of the low energy theorems of QCD calculated using chiral perturbation theory
(ChPT) which is based on the spontaneous breaking of chiral symmetry as well as
its explicit breaking due to the finite quark masses. As a result of the
vanishing of the threshold amplitudes in the chiral limit, the experiments are
difficult since the cross sections are small. Nevertheless the field has been
brought to a mature stage of accuracy and sensitivity. The accomplishments and
limitations of past experiments are discussed. Future planned experiments at
Mainz and HIS using polarization observables are discussed as a more
rigorous test of theoretical calculations. Emphasis is given to the technical
developments that are required for the HIS facility. It is shown that
future experiments will provide more accurate tests of ChPT and will be
sensitive to isospin breaking dynamics due to the mass difference of the up and
down quarks.Comment: 61 pages, 10 figures, 2 table
Free distribution of insecticidal bed nets improves possession and preferential use by households and is equitable: findings from two cross-sectional surveys in thirteen malaria endemic districts of Bangladesh
<p>Abstract</p> <p>Background</p> <p>BRAC, an indigenous non-governmental development organization (NGO), has been implementing a programme to prevent and control malaria in the 13 malaria-endemic districts of Bangladesh since 2007. One of the critical preventive interventions is the distribution of insecticidal bed nets (long-lasting insecticide-treated nets, LLINs and insecticide-treated ordinary nets, ITNs) to the community free of cost. This study aimed to assess progress in the possession, preferential use, and knowledge on use of the LLIN/ITNs including the programme's avowed pro-poor inclination one and three and half years after intervention began.</p> <p>Methods</p> <p>A convenient sampling strategy based on malaria endemicity in the districts was adopted. First, thirty <it>upazila </it>(sub-district, with a population around 250,000)<it>s </it>were selected at random, with high prevalent districts contributing more <it>upazilas</it>; second, from each <it>upazila</it>, one (2008) to two (2011) villages (covered by insecticidal bed net distribution programme) were selected. From each village, households that had either one under-five child and/or a pregnant woman were included in the survey, one household being included only once. Data were collected using a pre-tested structured questionnaire.</p> <p>Results</p> <p>In all, 3,760 households in 2008 and 7,895 households in 2011 were surveyed for collecting relevant information. Proportion of households with at least one LLIN, and at least one LLIN/ITN increased (22-59 to 62-67% and 22-64% to 74-76% respectively) over time, including increase in the mean number of LLIN/ITNs per household (≤ 1 to 1 +). The programme achieved > 80% coverage in sleeping under an LLIN/ITN in the case of under-five children and pregnant women, especially in the high-endemic districts. Knowledge regarding critical time of hanging the net also increased over time (7-22 to 44-54%), but remained low. The pro-poor inclination of the programme is reflected in the status of relevant indicators according to self-rated poverty status of the households.</p> <p>Conclusions</p> <p>There has been a substantial improvement in possession and usage of insecticidal bed nets especially for the two most vulnerable groups (under-five children and pregnant women), including a reduction of gaps between the high and low endemic districts, and the deficit and non-deficit households during the study period.</p
Malaria Prevalence in Endemic Districts of Bangladesh
BACKGROUND: Following the 1971 ban of DDT in Bangladesh, malaria cases have increased steadily. Malaria persists as a major health problem in the thirteen south-eastern and north-eastern districts of Bangladesh. At present the national malaria control program, largely supported by the Global Fund for AIDS, Tuberculosis and Malaria (GFATM), provides interventions including advocacy at community level, Insecticide Treated Net (ITN) distribution, introduction of Rapid Diagnostic Tests (RDT) and combination therapy with Coartem. It is imperative, therefore, that baseline data on malaria prevalence and other malaria indicators are collected to assess the effectiveness of the interventions and rationalize the prevention and control efforts. The objective of this study was to obtain this baseline on the prevalence of malaria and bed net use in the thirteen malaria endemic districts of Bangladesh. METHODS AND PRINCIPAL FINDINGS: In 2007, BRAC and ICDDR,B carried out a malaria prevalence survey in thirteen malaria endemic districts of Bangladesh. A multi-stage cluster sampling technique was used and 9750 blood samples were collected. Rapid Diagnostic Tests (RDT) were used for the diagnosis of malaria. The weighted average malaria prevalence in the thirteen endemic districts was 3.97%. In five south-eastern districts weighted average malaria prevalence rate was 6.00% and in the eight north-eastern districts weighted average malaria prevalence rate was (0.40%). The highest malaria prevalence was observed in Khagrachari district. The majority of the cases (90.18%) were P. falciparum infections. Malaria morbidity rates in five south-eastern districts was 2.94%. In eight north-eastern districts, morbidity was 0.07%. CONCLUSION AND SIGNIFICANCE: Bangladesh has hypoendemic malaria with P. falciparum the dominant parasite species. The malaria situation in the five north-eastern districts of Bangladesh in particular warrants urgent attention. Detailed maps of the baseline malaria prevalence and summaries of the data collected are provided along with the survey results in full, in a supplemental information

Are 'Village Doctors' in Bangladesh a curse or a blessing?
<p>Abstract</p> <p>Background</p> <p>Bangladesh is one of the health workforce crisis countries in the world. In the face of an acute shortage of trained professionals, ensuring healthcare for a population of 150 million remains a major challenge for the nation. To understand the issues related to shortage of health workforce and healthcare provision, this paper investigates the role of various healthcare providers in provision of health services in Chakaria, a remote rural area in Bangladesh.</p> <p>Methods</p> <p>Data were collected through a survey carried out during February 2007 among 1,000 randomly selected households from 8 unions of Chakaria <it>Upazila</it>. Information on health-seeking behaviour was collected from 1 randomly chosen member of a household from those who fell sick during 14 days preceding the survey.</p> <p>Results</p> <p>Around 44% of the villagers suffered from an illness during 14 days preceding the survey and of them 47% sought treatment for their ailment. 65% patients consulted Village Doctors and for 67% patients Village Doctors were the first line of care. Consultation with MBBS doctors was low at 14%. Given the morbidity level observed during the survey it was calculated that 250 physicians would be needed in Chakaria if the patients were to be attended by a qualified physician.</p> <p>Conclusions</p> <p>With the current shortage of physicians and level of production in the country it was asserted that it is very unlikely for Bangladesh to have adequate number of physicians in the near future. Thus, making use of existing healthcare providers, such as Village Doctors, could be considered a realistic option in dealing with the prevailing crisis.</p
