Comparison Of Anaesthetic Efficacy Of Inferior Alveolar, Gow-Gates And Vazirani-Akinosi Technique In Dentoalveolar Surgery

Background:Inferior alveolar nerve block has been widely used to anaesthetise the mandibular teeth. The other alternatives include the Gow-Gates and the Vazirani-Akinosi technique. This study aims to compare these three techniques of anaesthesia for posterior mandibular dentoalveolar surgery.Material & Method:Thirty subjects were equally distributed into three groups receiving the specific injection technique assigned to the group. The injection technique was performed using 3.6ml of 2% lignocaine with 1: 200000 adrenaline and clinical parameters such as onset of anaesthesia, pain in the injection site, extent of soft tissue anaesthesia and success rate of each block was assessed. Visual Analogue Scale was used to assess the pain experienced by the patient during theextraction procedure.Results:It was noted that the time taken for the onset of anaesthesia was the same in all the three groups. Vazirani-Akinosi group patients experienced significantly more pain on injection and during extraction of the tooth. Greaterextent of soft tissue anaesthesia was seen with the Gow-Gates technique when compared to the other two techniques. Conclusion:Gow-Gates technique demonstrated better efficiency when compared to the inferior alveolar or the Vazirani-Akinosi technique.

Epidemiological Assessment of Goiter.

Research Question: 1. What is the magnitude of problem of Goiter? 2. What is the level of iodised salt consumed by school children at school & home? Objectives: 1. To find out incidence of Goiter. 2. To find out level of iodised salt consumed by school children at school & home. Study Design: Cross-sectional study. Settings: School & houseto- house survey of urban & rural area of Raichur district. Participant: School children & general population of both sexes. Sample size: 45173. Statistical analysis: Proportion & Chi-squared test. Results: Total population covered 45173 in five talukas. Males were 23463 & females 21730, adult population 16404, children more than 15 yrs were 28769 & school population was 24984. School boys were 14269 & girls 10715. Highest prevalence of goiter found in Raichur taluka i.e. 5.68% and lowest in Lingsur taluka i.e. 0.86%. Over all prevalence of Goiter among surveyed villages is found to be 3.19 % (1439 cases). Higher prevalence has been reported among females in age group of 10- 14 yrs 5.25% & 15-19 yrs 4.66% compared to other age groups of village population. School children in Raichur district revealed the prevalence of Goiter 3.66%. Conclusion: Prevalence of Goiter among surveyed villages is found to be 3.19 % (1439 cases), which is less compared to the National figures. The people are consuming the iodated salt and ban on non-iodated salt may be effectively implemented in study region.

A case report of evans syndrome.

Evans Syndrome (ES) is the rare simultaneous or subsequent development of immune thrombocytopenia purpura (ITP) and autoimmune hemolytic anemia (AIHA). It portends a poorer prognosis and a more aggressive line of management than either condition presenting alone. Here we report a case of a young female who presented with both bleeding and acute decompensated anemia. Although she was successfully treated, mystery still shrouds the etiology, pathophysiology, as well as line of management of this rare and enigmatic disease.

Viral infections in newborns through exchange transfusion.

Preprocedure sera of thirty one neonates requiring exchange transfusion were tested for serological markers of HBV, HCV, CMV, HIV and LFT. All the babies were investigated for these parameters one week and two months after transfusion to evaluate the risk of transmission of viral infection. Serological markers for these viral infections were also studied in the mothers and donors' blood to establish the route of infection. Donors' blood used for transfusion was pretested for HBsAg, VDRL and anti-HIV. HBsAg was detected one week post exchange in one baby and two months post exchange in two babies. Exchange transfusion was implicated in two of them, where one donor had HBsAg and the other anti-HBc. Vertical transmission accounted for the remaining one. Out of these HbsAg positive cases, one showed evidence of recently acquired CMV infection. Vertical transmission of anti-HCV was observed in one case. None of the neonates, mothers and donors were positive for anti-HIV. In view of probable serious consequences of HBV and HCV infections, blood used for exchange transfusion ought to be screened for anti-HBc and anti-HCV, besides routine HBsAg, VDRL and anti-HIV screening.
