Why should breast surgeons use ultrasound?

Portable ultrasound is now used in a variety of clinical settings by specialties outside of radiology. Despite increased accessibility to ultrasound, the overall performance of ultrasound by breast surgeons is consistently low. We discuss the reasons why this is unacceptable for future patient care and answer the question, ‘Why should breast surgeons use ultrasound?’ We reviewed the literature for evidence assessing the outcomes of breast surgeon-performed ultrasound both intra-operatively and in the outpatient department. Intra-operative ultrasound performed by surgeons reduces re-excision rates in breast-conserving surgery. Outpatient-based ultrasound performed by surgeons frees up the resources of radiology departments, allowing them to focus upon patients requiring more complex diagnostic and interventional procedures. For surgeons to competently perform intra-operative and outpatient-based ultrasound, a period of formal ultrasound training is necessary to acquire knowledge of ultrasound skills and techniques. This should be followed by a period of mentorship and supervised training with an experienced breast radiologist. Breast surgeon-performed ultrasound is beneficial to the multi-disciplinary care of breast cancer patients. To further improve multidisciplinary care, breast surgeons and radiologists should work more collaboratively to optimise imaging applications both in the operating theatre and outpatient department. Current advances in therapeutic percutaneous techniques are of interest to both surgeons and radiologists. In future, a hybrid specialisation should be considered to incorporate accreditation in both specialties for breast interventional procedures.     

Educating Women for HIV Prevention: Does Exposure to Mass Media Make Them More Knowledgeable?

Mass media is an important vehicle for health promotion in developing countries. In Bangladesh multiple media campaigns are being carried out to educate people about HIV/AIDS. We examined the extent of HIV/AIDS knowledge and the association of exposure to mass media among women in Bangladesh. The Bangladesh Demographic and Health Survey (BDHS) provides data for this article. We found that media exposure (combined index of television, radio, and newspaper) was a highly significant predictor of women's knowledge about HIV and AIDS. Other significant predictors of HIV knowledge include women's education, age, employment, and urban residence.     

The role of radiologic,clinical and biochemical parameters in prediction of stroke mortality

Objectives:To assess National Institutes of Health Stroke Scale (NIHSS), stroke volume, biochemical, and blood parameters for the prediction of one-month mortality in stroke patientsMethods:The study had retrospective design and 75 patients were involved that presented to a hospital Emergency Department between January 2016 and December 2017 in Adiyaman, Turkey diagnosed with acute ischemic cerebral infarction. The patients were divided into 2 groups according to whether mortality occurred within one month. Values for NIHSS, stroke volume, Glasgow Coma Scale, and blood parameters were compared between the groups.Results:Values for Glasgow Coma Scale p=0.002, NIHSS p=0.001, stroke volume p=0.003, monocyte/HDL ratio p=0.047, neutrophils p=0.01, white blood cell p=0.007, calcium p=0.016, and albumin p=0.027 were statistically significant for the prediction of one-month mortality. There were no significant differences between the groups for other parameters.Conclusion:The clinical, laboratory, and radiological findings individually provide significant support for the short-term prognosis of stroke. The evaluation of these results together can provide a clearer advance understanding of a prognosis to better manage the course of the disease and prevent death.

Stroke is the third most common cause of death for patients presenting to emergency departments worldwide.1 Thus, to foresee possible mortality and morbidity in stroke cases, adoption of the right treatment and follow-up approach is important.2 The quality of the health service in a hospital emergency department depends on the successful prediction of the course of the disease and the clinical picture that may arise. Being aware of the prognosis of the disease in advance is important not only for making optimal treatment decisions but also for correctly informing the patient and managing health expenditures.In the literature, clinical parameters such as C reactive protein (CRP), red cell distribution width (RDW), neutrophil/lymphocyte ratio, and routine blood parameters such as albumin, infarct volume on admission, and National Institutes of Health Stroke Scale (NIHSS) score have previously been defined for the prediction of mortality in stroke cases.2-5 Pro-brain natriuretic peptides and pro-atrial natriuretic peptides, 2 other biochemical parameters that are not among the routine blood parameters, have also been shown to be important markers of stroke prognosis.6,7This study aimed to evaluate the association of clinical, biochemical, and radiological parameters with one-month mortality in patients that presented to the emergency service and received a diagnosis of ischemic stroke.     

Household Air Quality Risk Factors Associated with Childhood Pneumonia in Urban Dhaka,Bangladesh

To inform interventions to reduce the high burden of pneumonia in urban settings such as Kamalapur, Bangladesh, we evaluated household air quality risk factors for radiographically confirmed pneumonia in children. In 2009–2010, we recruited children < 5 years of age with pneumonia and controls from a population-based surveillance for respiratory and febrile illnesses. Piped natural gas was used by 85% of 331 case and 91% of 663 control households. Crowding, a tin roof in the living space, low socioeconomic status, and male sex of the child were risk factors for pneumonia. The living space in case households was 28% less likely than in control households to be cross-ventilated. Particulate matter concentrations were not significantly associated with pneumonia. With increasing urbanization and supply of improved cooking fuels to urban areas, the high burden of respiratory illnesses in urban populations such as Kamalapur may be reduced by decreasing crowding and improving ventilation in living spaces.     

Prevalence of pre-diabetes and associated risk factors in an adult Omani population

The Sultanate of Oman has experienced an epidemiological transition over the last 4 decades with rising tide of non-communicable disease such as type-2 diabetes. This study aims to estimate the prevalence of pre-diabetes and explore the associated demographic, clinical and biochemical risk factors among a semi-urban Omani population. A semi-urban satellite town, Bidbid, located about 30 km west of the capital, Muscat, was selected as the study setting. The targeted participants were Omani adults (18 to 60 years old) who had resided in Bidbid municipality for at least 6 months prior to enrollment in the study. Using multistage random sampling, 1,600 Bidbid residents were invited to participate in the study. The study protocol gathered data on the socio-demographic and clinical backgrounds of the participants. Participants’ impaired glucose tolerance (IGT) impaired fasting glucose (IFG) and cholesterol and triglyceride levels were then measured. The study surveyed 1,313 individuals (490 men and 823 women) out of 1,600 who had been invited to participate. The participation rate was higher among women than men (91.5% compared to 54.3%). A total of 459 individuals (35% of participants) were diagnosed as pre-diabetic by either the IGT or IFG test; 121 (9%) were pre-diabetic by virtue of both measurements. Male gender, advanced age and obesity were each independently associated with higher prevalence of pre-diabetes. Increased prevalence of pre-diabetes also correlated with the indices of hypercholesterolemia and dyslipidaemia. Pre-diabetes is a substantial health problem in Oman that may present a significant challenge to the national healthcare system in the near future. Customized interventions targeting groups with high risk of pre-diabetes, especially men, the elderly and the obese, are urgently needed.

MEFV mutations in familial Mediterranean fever: association of M694V homozygosity with arthritis

Objective Familial Mediterranean fever (FMF) is an autosomal recessive recurrent polyserositis with a higher prevalence in some ethnic groups, including Turks. Mutations in the FMF gene (MEFV) were found associated with FMF. The aim of this study was to analyze MEFV gene mutations in FMF patients to gain insight into the mutation phenotype correlation.Objectives We analyzed the most frequent mutations (M680I, M694V, V726A, and E148Q) in a group of young male Turkish FMF patients using an amplification refractory mutation system and a commercial kit.Results M694V mutation was detected in 80% of the patients. After making a strict diagnostic discrimination between arthralgia and arthritis, arthritis was present in 71% of homozygous and 29.4% of heterozygous patients for M694V mutation. Other mutations were not found to correlate with specific symptoms or findings.Conclusion The homozygosity of M694V mutation in the MEFV gene is associated with arthritis in FMF patients.     

Hereditary 1,25-dihydroxyvitamin D resistant rickets due to a mutation causing multiple defects in vitamin D receptor function

Hereditary vitamin D-resistant rickets (HVDRR) is an autosomal recessive disease caused by mutations in the vitamin D receptor (VDR). We studied a young Saudi Arabian girl who exhibited the typical clinical features of HVDRR, but without alopecia. Analysis of her VDR gene revealed a homozygous T to C mutation in exon 7 that changed isoleucine to threonine at amino acid 268 (I268T). From crystallographic studies of the VDR ligand-binding domain, I268 directly interacts with 1,25-dihydroxyvitamin D(3) [1,25(OH)(2)D(3)] and is involved in the hydrophobic stabilization of helix H12. We recreated the I268T mutation and analyzed its effects on VDR function. In ligand binding assays, the I268T mutant VDR exhibited an approximately 5- to 10-fold lower affinity for [(3)H]1,25(OH)(2)D(3) compared with the wild-type (WT) VDR. The I268T mutant required approximately a 65-fold higher concentration of 1,25(OH)(2)D(3) to be equipotent in gene transactivation. Both retinoid X receptor heterodimerization and coactivator binding were reduced in the I268T mutant. Analogs of 1,25(OH)(2)D(3) have been proposed as potential therapeutics for patients with HVDRR. Interestingly, in protease sensitivity assays, treatment with the potent vitamin D analog, 20-epi-1,25(OH)(2)D(3), stabilized I268T mutant proteolytic fragments better than 1,25(OH)(2)D(3). Moreover, 20-epi-1,25(OH)(2)D(3) restored transactivation of the I268T mutant to levels exhibited by WT VDR treated with 1,25(OH)(2)D(3). In conclusion, we describe a novel mutation, I268T, in the VDR ligand-binding domain that alters ligand binding, retinoid X receptor heterodimerization, and coactivator binding. These combined defects in VDR function cause resistance to 1,25(OH)(2)D(3) action and result in the syndrome of HVDRR.
