    Objective. To investigate the usefulness of immunological tests in the diagnosis of HIV infection in young symptomatic children < 15 months of age).Design. Tests were evaluated in HIV-infected (HIV antibody- and PCR-positive) patients and non-infected individuals.Setting. Hospitalised patients in a referral centre (Red Cross War Memorial Children's Hospital, Cape Town). Patients. All admissions under 15 months of age who had HIV antibody requested were eligible, provided there was sufficient serum (150 1-11) for further study. Overall, there were 201 symptomatic cases and 49 healthy controls. Twenty of the symptomatic cases were HIV antibody-positive and 19 of these were HIV-infected on the basis of a positive PCR for HIV viral productResults. Of the tests we evaluated (total IgG, IgM, IgA and rheumatoid factors of the same classes), raised total IgG level (cut-off 18 g/I or above) was the most useful. We used a commercial radial immunodiffusion plate which was found to have excellent reproducibility (inter-assay coefficient of variation 3.2%). The test detected 16 of 19 infected infants (sensitivity 84%, negative predictive value 98%). With the exception of the finding of oral thrush (odds ratio 7; P < 0.001), the clinical signs at presentation did not distinguish those who were HIV antibody-positive from those who were negative.Conclusions. In our study of hospital admissions, the finding of elevated IgG and HIV antibody was diagnostic of HIV infection. (The positive predictive value of the combination was 100%.) Likewise, the presence of raised IgG levels and oral candidosis had a high specificity for HIV infection (98%) but the sensitivity was low (37%).Measurement of total IgG levels by radial immunodiffusion is simple, relatively inexpensive < 10% of the cost of PGR), helpful in diagnosing HIV infection in symptomatic infants and able to be performed in areas with minimal laboratory back-up

    Bio-grouting technology is a technology that simulates the process of diagenesis which shows the\ud transformation of sand into sand stone (calcarinite/sandcone), calcite (CaCo3) which is formed from bio-grouting\ud process. They will function to bind the grains of sand which is causing the cementation process and transformation of\ud sand into stone. This research aims to determine the optimum composition of the bacillus subtilis bacteria solution for\ud soil stabilization and evaluate the mechanical characteristic of the soil that is stabilized with variations bacillus subtilis\ud bacteria solution and cementation solution, combined with variety of curing time. The soil testing for sandy clay soil\ud employed standard from SNI and ASTM. Method of experimental development testing was performed in an\ud experimental model with test the design of each size 7.2cm x 3.6cm, 6cm x 6,6cm, and 2cm x 6,4cm with grouting\ud method. The kinds of examinations conducted to analyze the result are test of unconfined compressive strength,\ud permeability, and direct shear. The volume of bacillus subtilis bacteria which are injected into the soil are 2cc to 32cc\ud with curing time 3, 7, 14, 21, and 28 days. The results of unconfined compressive strength test on laboratory scale\ud shows that testing without injection of bacteria is at 0.13 kg/cm2, for the sample injected with bacteria is at 0.35\ud kg/cm2. Permeability experiments without bacteria has coefficient value of 2.49.10-4cm/sec and the sample with the\ud injection of bacteria has coefficient value of 4.91.10-6cm/sec. Direct shear experiments without bacteria injected has\ud angle of internal friction 4.46 ?? and for the results with the injection of bacteria is 35.07??. It can be concluded that the\ud addition of bacteria for stabilization of sandy clay soil with bio-grouting method manages to increase the soil???s bearing\ud capacity.

    Morphological variability in unrepaired bilateral clefts with and without cleft palate evaluated with geometric morphometrics

    In subjects with orofacial clefts, there is an unresolved controversy on the effect of congenital maxillary growth deficiency vs. the effect of surgical intervention on the outcome of treatment. Intrinsic growth impairment in subjects with orofacial clefts can be studied by comparing facial morphology of subjects with untreated cleft and unaffected individuals of the same ethnic background. Bilateral cleft lip and palate is the most severe and least prevalent form of the orofacial cleft. The aim of this study was to compare facial morphology in subjects with unrepaired complete bilateral clefts and unaffected controls using geometric morphometrics. Lateral cephalograms of 39 Indonesian subjects with unrepaired bilateral complete cleft lip and alveolus (mean age: 24 years), or unrepaired bilateral complete cleft lip, alveolus, and palate (mean age: 20.6 years) and 50 age and ethnically matched controls without a cleft (25 males, 25 females, mean age: 21.2 years) were digitized and traced and shape variability was explored using principal component analysis, while differences between groups and genders were evaluated with canonical variate analysis. Individuals with clefts had a more pronounced premaxilla than controls. Principal component analysis showed that facial variation in subjects with clefts occurred in the anteroposterior direction, whereas in controls it was mostly in the vertical direction. Regression analysis with group, sex, and age as covariates and principal components from 1 to 6 as dependent variables demonstrated a very limited effect of the covariates on the facial shape variability (only 11.6% of the variability was explained by the model). Differences between cleft and non-cleft subjects in the direction of facial variability suggest that individuals with bilateral clefts can have an intrinsic growth impairment affecting facial morphology later in life.</p
