Growth Patterns of cranium measured directly as head circumference have been well documented. With the recent progress in CT, it is easy to measure the size and cross sectional area of the structure. The author chose themidvnetricular level of brain CT scan and measured the product of maximum anteroposterior and lateral dimension and cross sectional area. The age of infants ans children was 0 to 2 years old. The author obtained the following results through statistical analysis; 1. The maximum anteroposterior dimension and the cross sectional area were obtained through the computerized program of CT scanner. Using these measurements, monthly growth curve was obtained and which shows accelarated growth in the initial 12 months especially during the first four months, and followd by reduced rate of growth in the next 12 months. 2. Comparing the size of the calvarium between sexed,females' were somewhat larger than males', but there was no statistical significance. 3. Comparing the crosssectional area with the head circumference, high correlation was seen(correlation coefficient=0.96). Similarelationship was also seen between the product of cranial linear dimensions and the head circumference(correlationcoefficient=0.93). Also statistically significant relationship was noted between the cross sectional area and theproduct of the cranial linear dimensions(correlation coefficient=0.97). 4. Using the cross sectional area and theproduct of cranial linear dimenstions, monthly average value and the 95% significant range were obtained which canbe used as indices for the growth and development of cranium. Of these, the product of cranial linear dimensionscan eadily be measured by brain CT images, which may be useful on practical basis.

INTRODUCTIONThe prevalence of diabetes mellitus is high in Singapore. Infections of the lower limb are significant causes of morbidity in this population. Although the aerobic bacteriology of these infections is well-documented, there is less data available on the anaerobic pathogens involved. This study sets out to describe the anaerobic bacteria associated with diabetic foot infections, and evaluates the susceptibility to 3 antimicrobials with anaerobic activity.

MATERIALS AND METHODSAnaerobic culture was performed on operative samples taken from diabetic foot infections. Organisms were identified through standard microbiological methods and commercial identification kits. Antimicrobial susceptibility testing to clindamycin, metronidazole and imipenem was performed by agar dilution.

RESULTSOne hundred and two strains of strict anaerobic bacteria were isolated from 30 unique specimens. The predominant anaerobic isolates were Peptostreptococcus spp. (46%) and Bacteroides fragilis group (19%). Antibiotic resistance was detected for clindamycin (18%), metronidazole (1%) and imipenem (2%).

CONCLUSIONMultiple anaerobic species can be isolated from diabetic foot infections. A significant proportion of isolates are resistant to clindamycin, while resistance to imipenem and metronidazole remains low.

Arotinolol was administered orally to 31 patients to evaluate is antihypertensive action. After one week of antihypertensive medication, they were given Arotinolol 30mg daily for 4 week. Routine serum chemistries, electrolytes, urinalysis and electrocardiography were studied before and after Arotinolol. Blood pressure measured in sitting, supine and standing position was 175.3+/-5.4/115.7+/-4.0, 168.0+/-5.2/150.0+/-3.8, 154.4+/-8.5/103.4+/-3.2mmHg in control and 143.8+/-2.8/93.3+/-2.8, 144.6+/-5.4/88.1+/-4.3, 139.7+/-4.6/86.8+/-3.4mmHg in Arotinolol treatment group. The differences between both blood pressure were statistically significant(P<0.01). No laboratory test showed significant difference between both period. There were no significant side effects except 2 cases of transient headache and dizziness respectively, and one case of diarrhea. In summary, Arotinolol apears to reduce blood pressure effectively with minimal side effects.

BACKGROUND: There were many studies about the changes of cognitive or non-cognitive domain and behavioral and psychological symptoms with the progression of Alzheimer's disease. But they assessed the changes individually so could not explain comprehensively the global change of disease progression. Also they studied by clinical dementia rating scale(CDR) which could not successfully explain the latest stage. So we have evaluated the cognitive, non-cognitive domain and behavioral and psychological symptoms at the same time and evaluated the changes with the expanded clinical dementia rating scale. Also we evaluated the relationship of each scale and assessed sensitivity change at the different stage of disease. METHODS: Twenty-three mild cognitive impairment(MCI) subjects and eighty-seven patients with Alzheimer's disease were recruited. The Korean version of Mini-Mental State Examination(K-MMSE), the Korean version of the neuropsychiatric inventory(NPI), the Extended version of the Korean Clinical Dementia Rating Scale(CDR), the Activity of Daily Living(ADL), the Severe Dementia Scale(SDS) and the Short form of Samsung Dementia Questionnaire(S-SDQ) were performed. RESULTS: It was found that all of them were well correlated each other(r>-0.73 and p<0.05) except NPI. Physical activity of daily living(P-ADL) was most related to Korean version of instrumental activity of daily living(K-IADL) (r=0.86 and p<0.01), SDS to K-MMSE(r=0.93 and p<0.01) and S-SDQ to K-IADL(r=0.86 and p<0.01). P-ADL and S-SDQ revealed the ceiling effect at CDR 4 and K-IADL at CDR 3. CONCLUSION: The cognitive and non-cognitive function were declined according to disease progression. The changes of behavioral and psychological symptoms were relatively independent of cognitive function. SDS, P-ADL and CDR were proved to be more sensitive in advanced stage of dementia and K-IADL, S-SDQ were more adequate in milder stage of dementia or MCI.

INTRODUCTIONSuprascapular nerve neuropathy secondary to ganglion cyst impingement has increasingly been found to be a cause of shoulder pain.

CLINICAL PICTUREWe present 2 patients who complained of dull, poorly localised shoulder pain, which worsened with overhead activities. Magnetic resonance imaging showed ganglion cysts in the spinoglenoid notch.

TREATMENTBoth patients failed conservative management with physiotherapy and underwent shoulder arthroscopy. One patient underwent arthroscopic decompression of the cyst and the other had open excision of the cyst.

OUTCOMEBoth patients experienced resolution of symptoms within 6 months of surgery.

CONCLUSIONWith appropriate treatment, suprascapular nerve neuropathy secondary to ganglion cyst impingement is a treatable condition with potentially good results.

The increase of the burden of dengue and chikungunya and the relative failure of traditional vector control strategies have highlighted the need to develop new control methods. RIDL-SIT, a vector control method based on the release of engineered male mosquitoes, has shown promising results from field trials conducted in the Cayman Islands and Brazil. In large scale use, a small proportion of females might be released along with the males. Such females are potential virus vectors; here we investigate the vertical transmission of dengue and chikungunya of homozygous OX513A females.We provided females of OX513A-My1 and a wild type comparator strain with blood meals artificially infected with dengue serotype 1, 2, 3, 4 or chikungunya viruses. For 14 days post-feeding, eggs laid by females were collected. Larvae and their mothers were first tested by qRT-PCR, then by inoculation on cell cultures to search for infectious viral particles. We found no significant difference between the minimum infection rate of OX513A-My1 and wild type females. We also discussed the potential number of females being released, a fraction of the female wild population. Consequently, we conclude that there are no evidence that OX513A-My females, if released into the environment, would cause more harm than their wild counterparts.

The diagnostic value of the DNA polymerase chain reaction for the detection of M. tuberculosis in tuberculous meningitis uas established by using cerebrospinal fluids obtained from 7 bacteriologically confirmed patients (Group IA), 17 clinically diagnosed patients (Group IB), 21 patients with other bacterial or viral meningitis (Group IIA) and two norrnal persons (Group IIB) The PCR was perforrned with P1 and P2 primer set which directed against the 123bp segment of IS5110. A repetitive sequence of M. tuberculosis chromosome. The sensitivity and specificity of the PCR for the detection of M. tuberculosis was evaluated by using DNAs purified from cultured M tuberculosis and M intracellulare . The detection limit by the PCR amplication with Pl and P2 primer was lfg of DNA for M. tuberculosis and lpg for M. intracellulare indicating that the PCR was very sensitive for M. tubererculosis DNA detection; although weakly cross-reactive with DNA of M. tuberculosis. Of the 7 cerebrospinnal fluids from bacterologically proven tuberculous meningitis patients (Group IA), 7 samples were all positive by PCR (10Q%). 15 sarnples of 17 the AFB smear-negative and culture-negative samples from tuberculous meningitis patients (Group IB) were positive by PCR (88.2%) and 2 of 2l sanples from other meningitis patients (Group IIA) showed positive reaction (9.5%). There were no sarnples whick showed positive reaction by PCR among 2 sarnples from normal persons (Group IIB). This results indicated that the PCR using P1 and P2 primer set was useful for the early diagosis of tuberculous meningitis.
