2-D electrical resistivity tomography (ERT) is one of the geophysical methods applied in subsurface study for engineering purposes. The ERT result was correlated with 2 boreholes to identify the subsurface characteristic. The study location situated at PT 8088 and 8089, Rawang, Selangor, Malaysia with coordinate of 3° 15' 37.2" N and 101° 38' 48.22" . Four ERT survey lines were conducted at the study area with Pole-dipole array with 5m minimum electrode spacing, 5mA and 20mA of minimum and maximum d.c. current respectively. The ERT results show the study area consists of two main zones, alluvium with resistivity value of 10-800 Ωm, and granite bedrock with resistivity value of >2500 Ωm with depth 5-70m. Saturated zone and hard layer were detected with resistivity value of <110 Ωm and 1500-2500 Ωm respectively which indication of fractured zone. Borehole record, BH3 and BH5 show the overburden was alluvium (gravels with sand) and depth to granite bedrock was 25.5m and 12.0m respectively. © 2011 ejge. Source

Low birth weight (LBW) infants are those that weigh less than 2500g at the time of birth. They are 40 times more likely to die than normal weight infants are. The primary cause of LBW babies is preterm labor or premature rupture of membranes. Factors such as smoking, alcohol or drug abuse during pregnancy, inadequate prenantal care, race, low socio-economic status, hypertension, high or low maternal age, diabetes and chronic maternal infection, increase the risk of LBW babies. Periodontitis is a remote gram-negative infection that may play a role in LBW. Periodontopathic microorganisms and their products have wide range of effects mediated through host cytokine production in target cells. Many combined animal studies and data supporting plausible biological mechanisms suggest that periodontal infection has a negative impact on pregnancy outcome in some women. Source

Objective: To analyze the pattern of presentation and pathology of breast lump in adolescents and young female patients. Methods: Medical records of female patients below 30 years presenting with palpable breast lump at Liaquat University Hospital during August 2008 to July 2009 were retrospectively reviewed. Patients having acute mastitis, inflammatory carcinoma and recurrent malignant or benign lesions were excluded from study. Results: A total of 214 patients were included in study. Mean age was 22.11 years. Approximately 46% of the patients were at the age 20 or less. Most common mode of presentation was painless lump in 61.22% followed by pain and lump in 20.56%.The histopathology of resected specimen showed that fibroadenoma was the most common lump while benign phylloides was the least common. Carcinoma breast was identified in 25 cases, of which 3 cases were at age 20 or less. The commonest histopathology was infiltrating duct cell carcinoma (60%), followed by lobular carcinoma (16%), scirrhous carcinoma (12%) and medullary carcinoma in 8 %. The Paget's disease was found in 4%. Conclusion: We found an increased frequency of breast cancer in comparatively younger age. These findings suggest that any female patient with palpable breast lump should preferably be managed by surgeon with special interest and training in breast diseases. Source

Objective: The study investigated the experience of orofacial pain (OFP) symptoms and associated disability and psychosocial impact in community dwelling and institutionalized elderly people in Hong Kong. Methods: A community-based cross-sectional survey involving elders aged 60 years and above. Participants were recruited at social centres for the elderly and homes for the aged throughout Hong Kong. Elders who reported OFP symptoms in the previous four weeks took part. Standard questions were asked about OFP conditions in the previous month and the Manchester Orofacial Pain Disability Scale (MOPDS), the Oral Health Impact Profile (OHIP-14) and the General Health Questionnaire (GHQ-12) were administered. The MOPDS was translated and validated for use in Chinese elders. Results: 200 community dwelling and 200 institutionalized elders participated. Toothache was the most common symptom (62.0%) and burning sensation in the tongue was least common (0.5%). The distribution of pain symptoms, pain duration and severity and pain ratings were similar in both groups. The MOPDS (Chinese elders version) had good reliability and construct validity. The MOPDS and OHIP-14 summary scores was significantly higher in the institutionalized elderly (p<0.001 and p<0.013, respectively). Psychological distress (GHQ-12 score ≥4) was more common among the institutionalized elderly (11%) than the community dwelling elderly (4.0%, p=0.002). Conclusions: Orofacial pain symptoms were associated with significant disability and had a detrimental impact on psychological distress level and quality of life, particularly in the institutionalized elderly. There is a need to improve access to professional care and health-related outreach services generally for elderly people in Hong Kong. © BASCD 2012. Source

Manihot allemii M. J. Silva is described and illustrated as a new species, and its morphological affinities and conservation status is discussed. It is most similar to M. salicifolia Pohl in having a subshrubby and erect habit and in the general aspect of its unlobed leaves, but differs from it in having leaves that are conspicuously petiolate, an inflorescence that is a congested spike-like thyrse, entire and diminute bracts and bracteoles subtending flowers of both sexes, pistillate calyx that is deeply lobed with oblong lobes, and staminate flowers with 8 or 10 stamens. Both species belong to a group of 14 species recognized by their possession of entire and unlobed leaves, which are the subject of taxonomic studies by the second author. Some notes on the leaf anatomy of species of Manihot that have entire and unlobed leaves are also presented. © 2016 The Authors. Source
