Effects of bilateral superficial cervical plexus block on sevoflurane consumption during thyroid surgery under entropy-guided general anesthesia: a prospective randomized study / 대한마취과학회지

BACKGROUND: Bilateral superficial cervical plexus block (BSCPB) provides good postoperative analgesia, but its effect on anesthetic consumption is unknown. This study evaluated the effects of BSCPB on sevoflurane consumption during thyroid surgery. METHODS: Fifty patients were randomly allocated into groups A and B of 25 each in this prospective double-blind study. Group A received BSCPB with 20 ml 0.25% bupivacaine, whereas group B received 20 ml saline immediately before entropy-guided general anesthesia. Intraoperative hemodynamic parameters, end-tidal sevoflurane concentration, minimum alveolar concentration, and sevoflurane consumption were recorded. Postoperative pain was assessed using a visual analog scale, and the time of the first request for analgesia was noted. All side effects were recorded. RESULTS: Demographics were comparable. Mean sevoflurane consumption [for 30 min: group A = 7.2 (1.1) ml, group B = 8.8 (2.0) ml, P = 0.001; for 60 min: group A = 13.5 (1.7) ml, group B = 16.5 (3.9) ml, P = 0.002] and mean end-tidal sevoflurane concentration [for 30 min: group A = 1.2% (0.2%), group B = 1.4% (0.2%), P = 0.008; for 60 min: group A = 1.2% (0.1%), group B = 1.4% (0.2%), P = 0.010] were significantly lower in group A. Patients in group A had a longer duration of analgesia [361.6 (79.5) min vs. 151.0 (60.2) min, P < 0.001] compared to those in group B. CONCLUSIONS: Preinduction BSCPB during thyroid surgery significantly reduced sevoflurane consumption and increased the duration of postoperative analgesia.

Prevalence of goitre among school children in Belgaum District.

Objective. A school survey was conducted to estimate the prevalence of goitre among schoolchildren in Belgaum district. Methods. A cross-sectional study was conducted in primary, middle and high schools of villages selected. All the children of the selected schools were examined for the presence of goitre and the salt samples obtained from their homes were tested for iodine content. Results. Overall prevalence of goitre was 16.7%. Prevalence of palpable goitre was 16.4 % and visible goitre was very low (0.3%). Higher prevalence was found among females (21.1%) when compared to that of male children (12.8 %). Prevalence of goitre increased significantly with advancement of age until 16-yr. 72.1 % children were consuming rock salt and only 27.9 % were consuming powdered salt at their homes. Estimation of Iodine content in the salt samples showed that 68.7 % of the sample had inadequate iodine content. Prevalence of goitre was significantly high among children who consumed rock salt (16.2%) as compared to those who used powdered salt (11%). Conclusion. Strict implementation of salt codization and marketing in rural area is desired. Also health education programme be showed.

Effectiveness of reproductive health education among rural adolescent girls: a school based intervention study in Udupi Taluk, Karnataka.

BACKGROUND :Adolescence is the most important and sensitive period of one's life [1] . According to the World Health Organization (WHO) Expert Committee, adolescence is defined as the period between 10 and 19 years, the second decade of life. OBJECTIVE :To determine the effectiveness of an educational intervention program on knowledge of reproductive health among adolescent girls. SETTINGS AND DESIGN :This educational intervention study was carried out over a period of one year. A total of 791 rural girls in the age group 16-19 years were randomly selected from coastal villages in Udupi District, Karnataka. MATERIALS AND METHODS :Adolescent girls were educated regarding reproductive health and their awareness levels were evaluated immediately following intervention. STATISTICAL ANALYSIS :Data was tabulated and analyzed using SPSS version 11.0 for Windows. Findings were described in terms of proportions and percentages. Chi square test was used to test the effect of the intervention. RESULTS :A significant increase in overall knowledge after the intervention (from 14.4 to 68%, P < 0.01) was observed regarding contraception. Knowledge regarding ovulation, first sign of pregnancy and fertilization improved by 37.2% (95% CI = (35.2, 39.2), P < 0.001). Knowledge regarding the importance of diet during pregnancy improved from 66 to 95% following the intervention. CONCLUSION : This study clearly showed that an educational intervention program can bring about a desirable change in knowledge among adolescent girls regarding reproductive health.

Acceptability and effectiveness of a breast health awareness programme for rural women in India.

BACKGROUND: Breast cancer being one of the leading cancers among women in developing countries, prevention or identification of the disease at an early stage is of paramount importance in saving as well as improving the quality of life. Breast health awareness appears to be a pragmatic method for this. OBJECTIVE: To determine the acceptability and effectiveness of an educational intervention programme on breast health awareness for rural women by trained female health workers. SETTINGS AND DESIGN: Community based non-randomised educational intervention study carried out over a period of 1 year. Three hundred and sixty rural women in the age group 30--59 years were randomly selected (and age-wise stratified), from a coastal village in Southern India. METHODS: Women were educated on breast health and breast self-examination by specifically trained health workers and their awareness and proficiency levels were evaluated at the end of 1 and 3 months post-intervention. STATISTICAL ANALYSIS: This was done using the Statistical Package for Social Sciences Version 10. RESULTS: Following the educational intervention, a significant increase in overall awareness regarding breast cancer (z=-15.807; P< 0.001) as well as in the performance of self-examination of the breast 321/342 (93%) was observed. Forgetfulness or being too busy appeared to be the two most frequently perceived barriers. CONCLUSION: This study clearly shows that a community oriented educational intervention programme emphasizing on proper technique can bring about the desirable behavioural change among women.

Acute respiratory infections in children: a community based longitudinal study in south India.

A community based longitudinal study was conducted in Malpe, a coastal village of Udupi district, Karnataka state, to investigate acute respiratory infections (ARI) in children. A cohort of 91 children under 3 years of age were followed up for 1 year, leading to 2047 fortnightly observation. On an average every child had 11.3 months of follow up. The overall incidence of ARI was 6.42 episodes per child per year. On an average each episode lasted for 5.06 days. Mean duration of ARI during one year was 32.5 days per child. Most of the ARI episodes in children (91.3%) were of simple Cough & Cold (no pneumonia). However, 8.2% developed pneumonia and only 0.51% had severe pneumonia. Incidence of ARI was almost same in male and female children. There was no significant difference in incidence among various age groups. But the incidence of pneumonia was significantly higher among infants (p<0.00002). Children of poor housing with smoke producing conditions suffered more frequently (p,002).

Prevalence of goitre among school children in coastal Karnataka.

OBJECTIVE: A cross sectional study was conducted in the rural field practice area of Department of Community Medicine, KMC, Manipal to find out the prevalence of goitre among school children in the age group of 8-10 years. METHODS: A total of 722 children were selected from the study population by the method of probability proportion to size (PPS) stratified sampling giving due representation to both Government and private schools. Children were clinically examined for the presence of goitre and graded according to WHO guidelines. Urine and salt samples were collected from subsample to estimate the urinary iodine excretion level and iodine content in the salt respectively. RESULTS: Over all prevalence of goitre was 30 percent. Prevalence among males was 28.8 percent and among females it was 31.2 percent. In the both sexes goitre rate increased with the advancement of age. Prevalence of grade I and grade II goitre was 29.4 and 0.6 percent respectively. Prevalence of goitre was significantly higher among children who had urinary iodine excretion level less than optimum (<10 mcg/dl). Estimation of iodine content in the salt sample revealed that 48.3 percent of samples had adequate iodine content (>=15 ppm). There was significant increase in the goitre rate as the iodine content in the salt decreased (p=0.01). CONCLUSION: Prevalence of goitre among school children was high and therefore constituted a public health problem in this region.

Hemangiopericytoma of greater omentum.

A 67-year-old man presented with a painless abdominal lump. CT scan revealed a large vascular intraperitoneal mass. At laparotomy, a large, vascular tumor was seen to arise from the greater omentum, which was resected. At histology, this tumor was a benign hemangiopericytoma.

Socio-demographic and maternal determinants of low birth weight: a multivariate approach.

A community based study was conducted in the rural areas of Udupi taluk, Karnataka state of South India to identify the socio-demographic, maternal and obstetric determinants of low birth weight. All singleton live births that occurred in the study area during a one year period (October 1991 to September 1992) were included. A total of 2919 singleton child-mother pairs formed the basis of the analysis. Information about social, demographic and economic conditions of the families; maternal factors such as age, parity, quality of antenatal care and previous obstetric history were collected by interviewing the mothers and family members and verifying the available medical records through the field investigators especially recruited and trained for this purpose. Data was analyzed using multiple logistic regression model. Primis, elderly mothers and mothers who had not received good quality antenatal care were found to be more at risk of having low birth weight babies. Other significant determinants were family custom, socio-economic status and environmental sanitation.

Refresher training and continuing education for para-medical ophthalmic assistants.

This paper describes a refresher training and continuing education programme in clinical and community ophthalmology for para-medical ophthalmic assistants (PMOAs) conducted by the Lions Aravind Institute of Community Ophthalmology. The course participants included 60 PMOAs working either in district hospitals, primary health centres or mobile units from the districts in Maharashtra. Each training programme was spread over 43 hours in 4 days and included lectures, practical demonstrations, and hands-on training in the outpatient, inpatient, and operation theatre of the training institution. Participants were given exposure to outreach activities in an eye camp and a satellite eye centre resembling a district hospital. The PMOAs found the training to be useful and it was seen that areas like patient counselling, instrument and equipment maintenance, and assistance in the operation theatre for newer surgical procedures which were lacking in the basic training were fulfilled in this training programme. Regional Institutes of Ophthalmology, upgraded medical colleges, and other eye-care institutions which have facilities and manpower could organise similar refresher and continuing education programmes for PMOAs so that they could be utilised more efficiently in the blindness-control activities in the country.

Perinatal mortality in a rural district of south India.

Perinatal mortality is one of the most sensitive indices of maternal and child health. The perinatal mortality rate is an indicator of the extent of pregnancy wastage as well as of the quality and quantity of health care available to the mother and the newborn. A community based prospective study carried out on 13,214 births in South Kanara district between Oct. 1991-Sept. 1992 revealed a perinatal mortality rate (PNMR) of 44.65/1000 births. Among the various factors influencing perinatal mortality, breech deliveries and babies of multiple pregnancies had a very high perinatal mortality rate of 180.81/1000 births (adjusted odd's ratio: 4.90) and 128/1000 births (adjusted odd's ratio: 2.64). The previous bad obstetric history of the mother, parity and sex of the newborn were among the other important factors influencing the PNMR.

Clinical and laboratory profile of sixty patients with AIDS: a South Indian study.

Sixty patients who fulfilled the WHO case definition of acquired immunodeficiency syndrome (AIDS) were admitted and treated between January 1993 and June 1995 in JIPMER Hospital, Pondicherry, South India. Their mean age was 30.3 +/- 6.4 years. Male: female ratio was 5 : 1. The heterosexual route was the major mode of transmission (96.7%). Fever was the commonest presentation (98.3%), followed by weight loss (85%) and cough (36.7%). The commonest opportunistic infection seen was tuberculosis (pulmonary, extrapulmonary - single or in combination) followed by esophageal candidiasis. Cryptococcal meningitis, intestinal crytosporidiosis, CNS toxoplasmosis, Pneumocystis pneumonia and group B Salmonella septicemia were the other infections encountered. Ten out of the 38 patients with tuberculosis were followed up on antituberculous treatment for 6 months. Seven out of 18 patients with esophageal candidiasis were treated with ketoconazole.

Influence of parental literacy and socio-economic status on infant mortality.

The influence of parental literacy and socio-economic status (SES) on infant mortality rate (IMR) was studied. This report is only a part of much larger community-based prospective study conducted to determine the factors influencing infant mortality in Dakshina Kannada district of Karnataka, by the Department of Community Medicine, Kasturba Medical College, Manipal, with the financial assistance form IDRC, Canada. A total of 12,857 livebirths during the period of October 1, 1991, to September 30, 1992, where registered and followed up for one year. There were 391 infant deaths which gives an IMR of 30.4 per 1,000 livebirths. Univariate analysis and subsequent stepwise multiple logistic regression analysis revealed that, literacy and SES have a very significant role in reducing IMR.

Infant feeding--knowledge and attitudes in a rural area of Karnataka.

A study of the knowledge and attitude towards infant feeding was conducted in South India on a group of 300 mothers whose babies' ages from 3 days to 17 months. Most of the mothers opined that breast-feeding had to be initiated within 24 hours of birth. However, only 32% felt that breast milk should be the first feed, whereas 68% considered prelacteal feeds a necessity. 71% of the mothers considered 3 to 5 months to be the optimum duration of exclusive breast-feeding. 90% felt that cow's milk was an ideal supplement. 78.3% subscribed to the view that breast-feeding should continue beyond one year. A sizeable proportion expressed the need to discontinue breastfeeds during babies' or maternal illness, particularly diarrhoea. Our results will form the babies of the content and the target groups in our future health education programme.

Stool culture as a diagnostic aid in the detection of Entamoeba histolytica in the faecal specimens.

"The use of stool culture in Boeck & Drbohlav's biphasic amoebic medium as a routine diagnostic aid in the detection of Entamoeba histolytica in the faeces, is evaluated in the present study. A total of 3803 faecal specimens were examined for the presence of E.histolytica by direct smear, formalin ether concentration and culture during a study period of 1982-1990. A total of 259 stool specimens were positive for the parasite by any or all of these methods 42 (16.21%) stool specimen not cultured in Boeck & drbohlav's medium were possible by direct smear and concentration methods. 99 (38.22%) stool specimens were positive by all of these methods (direct smear, concentration and culture). The culture detected E. histolytica in additional 62 (23.93%) stool specimens which were negative by both the direct smear and concentration methods. Results of this study recommends the use of stool culture as a routine diagnostic aid in the laboratory, for the detection E. histolytica in the faeces".

Laryngectomy: a quality of life assessment.

Cosmetic disfigurement and loss of voice following a total laryngectomy can cause major psychosocial problems. Fifty patients who had undergone a total laryngectomy and completed more than six months following surgery, were randomly selected during a routine follow-up, and asked to answer a questionnaire, to asses their degree of disability and extent of rehabilitation. The questionnaire have five main components viz. general information, functional evaluation, vocal rehabilitation, social assessment and economic sequelae. Results revealed that these patients suffered from a significant decrease in social acceptance (70%), social activity (82%), sexual activity (62%), ability to communicate vocally (58%), and severe financial repercussions (78%). A large number of patients (40%) were dissatisfied with the present level of rehabilitation offered. Inspite of these problems the majority (80%) were willing to accept a total laryngectomy as treatment of their cancer. This emphasizes the need for greater interaction between the treating surgeon, speech therapist, occupational therapist, and psychotherapist to rehabilitate these patients adequately.

Clinical utility of serum thyroglobulin in metastatic disease.

We examined the usefulness of serum thyroglobulin (Tg) levels in 196 patients with metastatic disease. Of these, 51 patients had a thyroidal primary (40 differentiated, 7 medullary and 4 undifferentiated), 35 patients had a nonthyroidal primary and in 110 patients the primary site was not known. Serum Tg was raised in 74.5 per cent (38 of 51) patients with carcinoma of the thyroid and in 92.5 per cent (37 of 40) patients with differentiated thyroid carcinoma (DTC). Twelve (34.3%) patients with proved nonthyroidal malignancies and 34 (30.9%) patients with unknown primary origin had elevated serum Tg levels. Of the 110 patients with unknown primary site thyroidal primary in 10 patients (all with elevated serum Tg levels) and nonthyroidal primary in 38 patients (7 had raised serum Tg levels) could be established. The sensitivity (for DTC) and the specificity (for nonthyroidal primary) of serum Tg estimation were 94.0 per cent (47 of 50) and 74.0 per cent (54 of 73) respectively and for patients with distant metastases were 100 (29 of 29) and 85.1 per cent (40 of 47) respectively. The positive and the negative predictive values of serum Tg were 71.2 (47 of 66) and 94.7 per cent (54 of 57) respectively and for patients with distant metastases were 80.6 (29 of 36) and 100 per cent (40 of 40) respectively. Our findings suggest that for patients presenting with metastases (particularly distant metastases) of an unknown primary site, serum Tg estimation is of great value to identify or rule out the involvement of the thyroid as the primary organ.
