Worship Traditions in Pictorial Poetry
Praying to a deity for the sake of devotion is called worship. Tolkappiyam, the oldest book of Tamil, beautifully demonstrates that the deity has always been given priority in Tamil society. Even today, when we start an activity, it is customary for the Tamil community to start worshipping the deities of their clans and the deities of their choice. Worship arises from the lifestyle of the worshippers. Faith in God arises on the basis of the kind of social system a society has created and the system in which it receives its external necessities of life, such as food, clothing, and books. Just as the deities worshipped differed, so did the methods of worship in various ways. This can be understood from the literature created during the respective periods. That the worship of God was the first act of any action is evidenced by the fact that whatever kind of literature it may be, it began with the prayer to God. The pictorial poems, which are highlighted as one of the four poets sung together with the richness of literature combining painting, mathematics, and musical skills, are often sung in praise of God. Although there are many varieties of pictorial poems, among them, the types of pictorial poems that are in the form of bandham (a type) are the vehicles of God and are written in a form of worship associated with a God, which enriches the cult tradition of the Tamil community. In this way, the study identifies the pictorial poems arranged in the categories of Naga Bandham, Peacock Bandham, Anna Bandham, Vel Bandham, Ratha Bandham, Sivalinga Bandham, Malai Bandham, and Kamala Bandham
KNOWLEDGE REPOSITORIES AND KNOWLEDGEABLE ACTION
In spite of the importance of knowledge reuse much is still unknown about how knowledge management artifacts influence reuse in practice. In this paper we use the concept of scaffolding to explore how knowledge repositories influence knowledgeable action. We conceptualize anchoring and adjustment as the processes involved in the use of scaffolding such as knowledge repositories. By viewing reuse in terms of these mechanisms, we can begin to consider the reuse processes individually as involving (1) choice of document for reuse and (2) adaptation of the document’s suggested solution applied to a current problem. We suggest the document acts as an anchor to frame the current problem consistent with the problem solved in the document, and that the suggested solution is then adapted through the adjustment process to meet the needs of the current problem. We subsequently explore the factors that influence both anchor choice and adjustment
Evaluation of different types of chest symptoms for diagnosing pulmonary tuberculosis cases in community surveys
Background: Prevalence of tuberculosis (TB) is an important epidemiological index to measure the load of the
disease in a community. A series of disease surveys were undertaken in rural community in Tiruvallur district in
Tamilnadu, south India
Objective: To investigate the yield of pulmonary tuberculosis (TB) cases by different symptoms status and suggest
predominant symptoms for detection of cases in the community based surveys.
Methods: Three disease surveys were conducted during 1999-2006, in a random sample of 82,000 adults aged > 15
years to estimate the prevalence and incidence of pulmonary TB. All subjects were screened for chest symptoms
and chest radiography. Sputum examination was done among those who were either symptomatic or abnormal on
X-ray or both. Cases observed through symptom inquiry were included for analysis.
Results: In survey-I, 65.6% had cough of > 14 days and yielded 79.1% of the total cases. In surveys II and III,
symptomatic subjects with cough contributed 69.5% and 69.2% of the cases respectively. In survey I, 26.8% had
symptoms without cough but with at least chest pain > 1 month contributed 8.4% of total cases. The corresponding
proportions in subsequent surveys were 29.3, 11.5%; and 23.4, 11.2% respectively. The number of symptomatics
without cough and chest pain but with fever > 1 month was negligible.
Conclusion: The relative importance of cough as a predominant symptom was reiterated. The yield of pulmonary
TB cases from symptomatics having fever of > 1 month was negligible. Fever may be excluded from the definition
of symptomatics for screening the population in community survey
Survival of tuberculosis patients treated under DOTS in a rural tuberculosis unit (TU), south India.
Objective: To estimate survival probabilities and identify risk factors for death of tuberculosis (TB) patients during
treatment period.
Methods: TB patients registered during May 1999 to December 2004 from a rural TB unit (TU) with a population of
580 000 in Tiruvallur district, South India, formed study population. Life table and Cox’s regression methods were used.
Results: Of the 3818 TB patients who were initiated on treatment, 96, 94 and 97% of category – I, II and III
respectively, were surviving after completion of treatment. Higher death rates were independently associated with
patient’s age (45 years), previous history of treatment, alcoholism and initial body weight (<35 kgs).
Conclusion: The survival probability was found to be similar in all patients irrespective of categorization. Necessary
actions need to be initiated in the programme to improve body weight and abstain from alcoholism
Weight gain in patients with tuberculosis treated under directly observed treatment short-course (DOTS)
Set up: One Tuberculosis Unit (TU) in Tiruvallur district, Tamil Nadu, India where Tuberculosis (TB) patients treated
under Directly Observed Treatment Short Course (DOTS) programme.
Objective: To identify the effects of weight gain among TB patients at the end of treatment on different factors such
as socio-economic and demographic characteristics, smoking and drinking habits, treatment under supervision, the type
of DOTS centres and problems in taking drugs.
Methods: TB patients registered between May 1999 and December 2004 formed the study population. Multiple
regression method was used for the analysis.
Results: Among 1557 smear-positive TB patients registered under DOTS programme, the changes in weight ranged
from a loss of 4 kgs to a gain of 20 kgs at the end of TB treatment; the average change in weight was 3.22 kgs. The gain
in weight at the end of treatment was associated with age (<45 years), DOT at government centres, no problems in taking
drugs as reported by patients and cure rate.
Conclusion: The findings showed that there is an association between gain in weight with DOT at government centres
and cure of patients
Value of dual testing for identifying tuberculous infection
Setting: A rural community in Chingleput district in Tamil Nadu state in south India.
Objective: To determine the value of dual testing with PPD-S and PPD-B for
identifying subjects with a tuberculous infection.
Design: About 240,000 subjects in rural south India, all of whom were tested
initially with PPD-S and PPD-B, were followed up for 15 years, mainly by total
population survey once in every 212
years. The incidence of culture-positive
tuberculosis was estimated using life-table technique.
Results: Among 17,530 subjects with an intermediate reaction (8–11 mm) to PPD-S
at intake, 285 with an induration to PPD-S exceeding the induration to PPD-B by at
least 2 mm, had a significantly higher incidence of culture-positive tuberculosis than
the remaining (154 and 93 per 100,000), and similarly 481 who had an induration of
o10mm to PPD-B compared to those with X10mm (131 and 93 per 100,000). These
subjects may be regarded as having a tuberculous infection.
Infection with non-tuberculous mycobacteria conferred protection of about 30%
against the development of tuberculosis over a 15-year period.
Conclusion: In subjects with an intermediate reaction (8–11 mm) to PPD-S, dual
testing with PPD-B enabled identification of those with a tuberculous infection. Most
of the reactions were due to non-tuberculous mycobacteria
Failure to initiate treatment for tuberculosis patients diagnosed in a community survey and at health facilities under a DOTS programme in a district of south India
We studied the proportion and fate of tuberculosis patients who were not initiated on treatment (initial
defaulters) in Tiruvallur district of Tamilnadu, where DOTS strategy was implemented. These patients were visited to
find out the reason for default. Treatment was not initiated in 57 (23.5%) of the 243 sputum positive cases diagnosed
in a community survey and 156 (14.9%) of 1049 patients diagnosed in health facility. Men were more likely not to have
treatment initiated. The common reasons stated for initial default were unwillingness, symptoms being mild, personal
reasons and dissatisfaction. There is an urgent need to improve the patient’s perception of treatment and strengthen the
health systems’ capabilities to reduce initial default
Impact of BCG vaccination on tuberculin surveys to estimate the annual risk of tuberculosis infection in south India
Background & objectives: Annual risk of tuberculosis infection (ARTI) computed from prevalence
of infection measures the extent of tuberculosis transmission in the community and it is used to
monitor the tuberculosis control programme. This is usually derived from tuberculin surveys among
children not vaccinated with BCG. This study explores whether the estimated ARTI among BCG
vaccinated children is comparable to that of unvaccinated children.
Methods: Three tuberculin surveys were undertaken among children aged <10 yr as part of assessing
the impact of DOTS implemented in Tiruvallur district, south India. The prevalence of infection
was estimated using the anti-mode method among vaccinated and unvaccinated children. The ARTI
was computed separately and compared in all the three surveys.
Results: The prevalence of infection among unvaccinated and vaccinated children in the first survey
were 7.8 per cent (95% CI: 7.1-8.6) and 7.9 per cent (95% CI: 7.1-8.8) respectively (ARTI was
estimated to be 1.6 per cent in both groups) and the difference was not statistically significant. The
corresponding figures for children test read in the second and third surveys were 6.9 per cent
(95% CI: 6.2-7.6) and 6.8 per cent (6.0-7.5) and; 6.0 per cent (5.2-6.7) and 6.0 per cent (5.5-6.5)
respectively. The computed ARTI was respectively 1.4 and 1.2 per cent among unvaccinated children
in the second and third surveys; and 1.4 and 1.2 per cent among vaccinated children in the second
and third rounds.
Interpretation & conclusion: There was no difference in the infection with Mycobacterium tuberculosis
among vaccinated and unvaccinated children. BCG vaccinated children may thus be included for
estimation of infection to assess the extent of transmission in the community as well as for monitoring
purpose
Quality of symptom elicitation in an epidemiological survey on tuberculosis
The quality of symptom elicited by health workers in an epidemiological survey on tuberculosis was
assessed by again subjecting a 10% random sample of the persons interviewed, by the supervisory staff, independently.
Three thousand four hundred and forty nine persons were thus interviewed twice. The overall estimates for overdiagnosis
and under-diagnosis in the elicitation of symptoms by health workers were to the extent of 16% and 8%
respectively, with minimal yield of sputum positivity from the discordant groups of persons. The additional load of 16%
for sputum examination can thus be considerably reduced if health workers are well trained in symptom-elicitationscreening
of the population and their work is monitored through spot supervisory checks
A Prospective study of functional outcome of bicondylar tibial plateau fracture managed with locking compression plate
INTRODUCTION:
Tibial plateau fractures account for 1% of all fractures in adults and
8% in elderly. Fractures of tibial plateau more common in recent days
due to increasing number of road traffic accidents. These fractures
resulting from direct axial compression (valgus) and indirect coronal
forces. The injuries span a wide spectrum, ranging from low energy
unicondylar fractures to high energy bicondylar and comminuted
fractures.
In addition, in elderly with osteoporotic bones, even low energy
injuries such as domestic falls may lead to complex tibial plateau
fractures. Hence the treatment of proximal tibial fractures has
become a challenge for the orthopaedic surgeons.
LCP has the advantages of better distribution of forces along the axis of
bone. They can be inserted with minimal soft tissue stripping using
minimally invasive percutaneous plate osteosynthesis (MIPPO).
Substantially reducing failure of fixation in osteoporotic bones. Reducing
the risk of a secondary loss of intraoperative reduction by locking with
screws to the plate. Unicortical fixation option. Better preservation of
blood supply to the bone as a locked plating does not rely on plate bone
compression. Provide stable fixation by creating a fixed angle construct
and angular stability.
LCP is technically mature and as it offers numerous fixation possibilities
and has proven to worth in complex fracture situations and in
osteoporotic bones.

plateau fractures treated with locking compression plate ..The analysis of
the results made in terms of age of patients, gender distribution ,
Laterality of fracture ,mode of injury , analysis of the types ,medial
condyle fracture planes ,primary bone grafting ,method of reduction and
fixation ,pre operative external fixation , dual plating , associated injuries
and complications .
In our study maximum incidence involving tibial plateau fracture >40 yrs
(81%) . Average age group in our study was 51.25 years compared to
Gosling et al 2005 study (Average age group 51.5 years)
CONCLUSION:
At the end of our study, following conclusions could be drawn
from the treatment of proximal tibial fracture with locking compression
plate.
Early mobilization is possible with LCP because of absolute
stability given by the implant and this contributes to better knee
range of motion .
Medial condyle coronal fracture and small posteromedial fragment
should be buttressed by posteromedial plating .
LCP gives the promising results in osteoporotic bones .It prevents
collapse of fracture both intraoperatively and postoperatively .
Not all bicondylar fractures are same ,treatment should be precise
to individual fracture pattern .
Bicondylar tibial plateau fractures treated with locking
compression plate have an excellent to good functional outcome
with very minimal wound complication
