The ideal anesthetic drug choice for local infiltration anesthesia under monitored anesthesia care must provide analgesia and patients’ comfort along with a bloodless surgical field for patients. We hypothesized that dexemedetomidine can provide better visibility of the surgical field at a higher dose of 1 µg/kg than 0.5 µg/kg, along with providing sedation and analgesia. Methods: After institutional ethics committee clearance and written informed consent, this prospective, randomized, triple blind study was conducted on ninety patients, between 18- 65 years who were scheduled for tympanoplasty. The patients were randomly assigned to either the dexmedetomidine (DEX) 0.5 group or the DEX 1.0 group, and received 10 ml solution containing 2% lignocaine with 0.5 µg/kg dexmedetomidine, or the 1 µg/kg dexmedetomidine. The operative surgeon performed local infiltration using standardized 5-point infiltration technique around the auricle. The primary objective was to compare the intraoperative bleeding at the surgical site. The comparison of normally distributed variables was conducted using the Student’s t-test, whereas non-normally distributed variables was compared using the Mann-Whitney U test. The analysis of qualitative data was conducted using the chisquare/Fisher’s exact test. A P value less than 0.05 was considered statistically significant. Results: The overall bleeding score was significantly higher in the DEX 0.5 group (3.21 ± 0.727) than the DEX 1.0 group (1.43 ± 0.661) (P value < 0.001). The time to first analgesic requirement and surgeon satisfaction score were also significantly higher in the DEX 1.0 group. Conclusions: Combining dexmedetomidine at a dose of 1 µg/kg with 2% lignocaine for infiltration provided improved analgesia and improved the surgical field during tympanoplasty performed under monitored anesthesia care.

Malaria elimination and control require prompt and accurate diagnosis for treatment plan. Since microscopy and rapid diagnostic test (RDT) are not sensitive particularly for diagnosing low parasitemia, highly sensitive diagnostic tools are required for accurate treatment. Molecular diagnosis of malaria is commonly carried out by nested polymerase chain reaction (PCR) targeting 18S rRNA gene, while this technique involves long turnaround time and multiple steps leading to false positive results. To overcome these drawbacks, we compared highly sensitive cytochrome oxidase gene-based single-step multiplex reaction with 18S rRNA nested PCR. Cytochrome oxidase (cox) genes of P. falciparum (cox-III) and P. vivax (cox-I) were compared with 18S rRNA gene nested PCR and microscopy. Cox gene multiplex PCR was found to be highly specific and sensitive, enhancing the detection limit of mixed infections. Cox gene multiplex PCR showed a sensitivity of 100% and a specificity of 97%. This approach can be used as an alternative diagnostic method as it offers higher diagnostic performance and is amenable to high throughput scaling up for a larger sample size at low cost.

Objective:
Schizophrenia is a serious disease characterized by impairment in the perception or expression of reality, leading to occupational and social dysfunction. The use of antipsychotic medication is now universal in the first-line treatment of schizophrenia. This study was undertaken to compare the efficacy of asenapine with a standard atypical antipsychotic, olanzapine in treating this disease.
Methods:
It was designed as a single blind, randomized, controlled, parallel group, single centre Phase IV trial of a newer atypical antipsychotic, asenapine versus existing standard atypical antipsychotic, olanzapine. Total 80 subjects were enrolled as per eligibility criteria.Each recruited subject received daily treatment with the trial medication (Olanzapine 10 mg or Asenapine 10 mg daily) for duration of 12 weeks. BPRS, CGI-S, CGI-I, Laboratory parameters and compliance was assessed and analyzed. Continuous variables were compared by t test and non-parametric data was analyzed by Mann−Whitney U test and Wilcoxon signed rank test. Likely categorical variables were analyzed by chi-square test or Fisher’s exact test, as appropriate.
Results:
The duration of schizophrenia at presentation was comparable in both the treatment groups. There was significant reduction of BPRS score between any two visits of each treatment groups. The decline in CGI-S and CGI-I scores was statistically significant (p < 0.001) when compared between visits of any of the both treatment arms.Adherence to treatment was excellent for all patients.
Conclusion
Newer atypical antipsychotic asenapine is more effective than standard olanzapine in reducing the symptoms of schizophrenia in this study and further larger studies are to be done.

Objective: To investigate the therapeutic efficacy of andrographolide, a plant derived compound, against chikungunya virus (CHIKV) infection. Methods: Using flow cytometry and immunoblotting assay, in vitro viral protein expression was studied in THP-1 cells line. In Balb/c mouse neonates, viral RNA copy number was determined by real time PCR. Results: The results showed reduced CHIKV protein expression on andrographolide treatment in CHIKV-infected human peripheral blood mononuclear cells, Vero cells and THP-1 cell line. In vivo, andrographolide treatment to CHIKV-infected neonates reduced viral RNA copy number. Further, andrographolide also increased cytotoxic T lymphocytes both in vitro and in vivo. Andrographolide also activated host innate immune pathways, viz., protein kinase R, phosphorylated eukaryotic initiation factor 2α , retinoic acid inducible gene-I and interferon regulatory factor 3/7, thereby increasing IFN- α secretion. CHIKV-induced nuclear factor κ light chain enhancer of activated B cells and tumor necrosis factor- α was also reduced on andrographolide treatment. Conclusion: Andrographolide inhibits CHIKV by suppressing viral protein expression and up-regulating host innate immunity and hence could be an effective therapeutic agent against CHIKV infection.

Throughout the years, various classifications have evolved for the diagnosis of vascular anomalies. However, it remains difficult to classify a number of such lesions. Because all hemangiomas were previously considered to involute, if a lesion with imaging and clinical characteristics of hemangioma does not involute, then there is no subclass in which to classify such a lesion, as reported in one of our cases. The recent classification proposed by the International Society for the Study of Vascular Anomalies (ISSVA, 2014) has solved this problem by including non-involuting and partially involuting hemangioma in the classification. We present here five cases of vascular anomalies and discuss their diagnosis in accordance with the ISSVA (2014) classification. A non-involuting lesion should not always be diagnosed as a vascular malformation. A non-involuting lesion can be either a hemangioma or a vascular malformation depending upon its clinicopathologic and imaging characteristics.
