		                        			 Background:
		                        			Craniosynostosis is a condition characterized by a premature fusion of one or more cranial sutures. The surgical repair of craniosynostosis causes significant pain for the child. A key focus of craniosynostosis repair is developing effective strategies to manage perioperative pain. This study aimed to review perioperative pain control strategies for craniosynostosis repair systematically. 
		                        		
		                        			Methods:
		                        			Guidelines for reporting systematic reviews and meta-analyses were used in the design of this review. In May 2022, the following databases were used to conduct the literature search: MEDLINE, Cochrane, EMBASE, and Google Scholar. A search was performed using MeSH terms “craniosynostosis,” “pain management,” and “cranioplasty.” 
		                        		
		                        			Results:
		                        			The literature review yielded 718 publications. After applying our inclusion criteria, 17 articles were included, accounting for a total of 893 patients. During the postoperative period, most studies used multimodal analgesia, primarily opioids, and acetaminophen. In the postoperative period, oral ibuprofen was the most commonly used NSAID, rectal codeine, and acetaminophen were the most commonly used weak opioids, and continuous remifentanil infusion was the most commonly used potent opioid. 
		                        		
		                        			Conclusion
		                        			The authors determined the best pain management options for pediatric patients undergoing cranioplasty by analyzing the most commonly used analgesics. A high-quality clinical trial comparing different types of analgesic combinations would be a valuable addition to the present literature.

		                        			 Background:
		                        			and Purpose Recent studies suggested an increased incidence of cerebral venous thrombosis (CVT) during the coronavirus disease 2019 (COVID-19) pandemic. We evaluated the volume of CVT hospitalization and in-hospital mortality during the 1st year of the COVID-19 pandemic compared to the preceding year. 
		                        		
		                        			Methods:
		                        			We conducted a cross-sectional retrospective study of 171 stroke centers from 49 countries. We recorded COVID-19 admission volumes, CVT hospitalization, and CVT in-hospital mortality from January 1, 2019, to May 31, 2021. CVT diagnoses were identified by International Classification of Disease-10 (ICD-10) codes or stroke databases. We additionally sought to compare the same metrics in the first 5 months of 2021 compared to the corresponding months in 2019 and 2020 (ClinicalTrials.gov Identifier: NCT04934020). 
		                        		
		                        			Results:
		                        			There were 2,313 CVT admissions across the 1-year pre-pandemic (2019) and pandemic year (2020); no differences in CVT volume or CVT mortality were observed. During the first 5 months of 2021, there was an increase in CVT volumes compared to 2019 (27.5%; 95% confidence interval [CI], 24.2 to 32.0; P<0.0001) and 2020 (41.4%; 95% CI, 37.0 to 46.0; P<0.0001). A COVID-19 diagnosis was present in 7.6% (132/1,738) of CVT hospitalizations. CVT was present in 0.04% (103/292,080) of COVID-19 hospitalizations. During the first pandemic year, CVT mortality was higher in patients who were COVID positive compared to COVID negative patients (8/53 [15.0%] vs. 41/910 [4.5%], P=0.004). There was an increase in CVT mortality during the first 5 months of pandemic years 2020 and 2021 compared to the first 5 months of the pre-pandemic year 2019 (2019 vs. 2020: 2.26% vs. 4.74%, P=0.05; 2019 vs. 2021: 2.26% vs. 4.99%, P=0.03). In the first 5 months of 2021, there were 26 cases of vaccine-induced immune thrombotic thrombocytopenia (VITT), resulting in six deaths.  
		                        		
		                        			Conclusions
		                        			During the 1st year of the COVID-19 pandemic, CVT hospitalization volume and CVT in-hospital mortality did not change compared to the prior year. COVID-19 diagnosis was associated with higher CVT in-hospital mortality. During the first 5 months of 2021, there was an increase in CVT hospitalization volume and increase in CVT-related mortality, partially attributable to VITT.

		                        			Introduction: Uncontrolled empirical treatment of urinary tract infections (UTIs) has negative aspect on predicting
the emergence of antimicrobial resistance and knowledge of those patterns has become extremely important
from time to time. Therefore, the aim of the present study was to check the prevalence and resistance patterns of
uropathogens in the community acquired UTIs. Methods: A total of 7132 urine samples were combined from male
3131 (43.9%) and female 4001 (56.1%) outpatients suspected of having UTIs, respectively over a three-year period
and cultured on routine culture media. The bacteria have been identified using basic biochemical tests, and sensitivity
to various antibiotics was determined by the method of disk diffusion. Results: Of 7132 urine samples 797
(11.2%) yielded significant uropathogens. Among the bacterial species, Escherichia coli was the major causative
agent of UTIs for both gender (63.7%), followed by Klebsiella spp (20.8%), Enterococcus faecalis (5.3%), Pseudomonas
spp (4.1%), Proteus spp (3.1%), Enterobacter spp (1.5%), Candida albicans (0.6%), Staphylococcus saprophyticus
(0.5%), Providencia spp (0.1%) and Staphylococcus aureus (0.1%). The antibacterial sensitivity testing
for E. coli, to commonly used antibiotics were showed variable resistant as follows: Ampicilln (78%), Amoxicillin
(71%), trimethoprim sulfamethoxazole (42%), Amox/clav. (14%) gentamicin (20%), nitrofurantoin (11%), nalidixic
acid (22%), ciprofloxacin (20%), Imipenem (16%),Ceftazidim (26%),Cefotaxim (25%),Ceftriaxon (21%),Cefuroxim
(33%). Conclusions: The findings showed that antimicrobial resistance patterns of uropathogens in variable, and
continuous monitoring of resistance patterns by using of antibiotic susceptibility testing in the laboratory is the most
appropriate to treat UTIs rather than the choice of UTIs empirical treatment.

		                        			 Pandemic H1N1 influenza virus respiratory illness has become an inevitable global
health concern. With antigenic drift, it becomes necessary to have drugs over tailor-made
HIN1 vaccine every year. In the current study, we screened many Piperine derivative in
which, N-5-(3,4-dimethoxyphenyl)-2E,4E-pentadienylpiperidine (AB05) and was further studied
for anti-H1N1influenza virus activity and compared with other stains in-vitro on MDCK cell
line. Initial cytotoxic doses of AB05 for the MDCK cell line were > 25µM. The results showed
a dose-dependent reduction of the viral plaque’s in the adsorption assay with EC50 of 0.33 µM.
The mechanism of AB05 was by inhibition of matured viral release as evaluated by the time
of virus addition with incubation of 6-10 hours. With the promising H1N1 virucidal activity of
AB05, we included various strains of human influenza virus to screen AB05 inhibition of
Neuraminidase (NA). The result showed 70% NA inhibition in WSN (H1N1), 90% in H3N2 &
Influenza B and 49% in Tamiflu resistant H1N1). Further our In silco docking studies
substantiated experimental results by showing the difference in binding and cooperation
between H1N1 and N3N2. Together these observations illustrate that Piperine derivative
AB05 is a promising lead molecule which needs further evaluation in animal models.

		                        			Dengue is a common infection, caused by dengue virus. There are four different
dengue serotypes, with different capacity to cause severe dengue infections. Besides,
secondary infections with heterologous serotypes, concurrent infections of multiple dengue
serotypes may alter the severity of dengue infection. This study aims to compare the severity
of single infection and concurrent infections of different combinations of dengue serotypes
in-vitro. Human mast cells (HMC)-1.1 were infected with single and concurrent infections of
multiple dengue serotypes. The infected HMC-1.1 supernatant was then added to human
umbilical cord vascular endothelial cells (HUVEC) and severity of dengue infections was
measured by the percentage of transendothelial electrical resistance (TEER). Levels of IL-
10, CXCL10 and sTRAIL in HMC-1.1 and IL-8, IL-10 and CXCL10 in HUVEC culture supernatants
were measured by the ELISA assays. The result showed that the percentage of TEER values
were significantly lower in single infections (p< 0.05), compared to concurrent infections on
day 2 and 3, indicating that single infection increase endothelial permeability greater than
concurrent infections. IL-8 showed moderate correlation with endothelial permeability (r >
0.4), indicating that IL-8 may be suitable as an in-vitro severity biomarker. In conclusion, this
in-vitro model presented few similarities with regards to the conditions in dengue patients,
suggesting that it could serve as a severity model to test for severity and levels of severity
biomarkers upon different dengue virus infections.

		                        			PURPOSE: Extrafine-particle inhaled corticosteroids (ICS) have greater small airway deposition than standard fine-particle ICS. We sought to compare asthma-related outcomes after patients initiated extrafine-particle ciclesonide or fine-particle ICS (fluticasone propionate or non-extrafine beclomethasone). METHODS: This historical, matched cohort study included patients aged 12-60 years prescribed their first ICS as ciclesonide or fine-particle ICS. The 2 cohorts were matched 1:1 for key demographic and clinical characteristics over the baseline year. Co-primary endpoints were 1-year severe exacerbation rates, risk-domain asthma control, and overall asthma control; secondary endpoints included therapy change. RESULTS: Each cohort included 1,244 patients (median age 45 years; 65% women). Patients in the ciclesonide cohort were comparable to those in the fine-particle ICS cohort apart from higher baseline prevalence of hospitalization, gastroesophageal reflux disease, and rhinitis. Median (interquartile range) prescribed doses of ciclesonide and fine-particle ICS were 160 (160-160) µg/day and 500 (250-500) µg/day, respectively (P<0.001). During the outcome year, patients prescribed ciclesonide experienced lower severe exacerbation rates (adjusted rate ratio [95% CI], 0.69 [0.53-0.89]), and higher odds of risk-domain asthma control (adjusted odds ratio [95% CI], 1.62 [1.27-2.06]) and of overall asthma control (2.08 [1.68-2.57]) than those prescribed fine-particle ICS. The odds of therapy change were 0.70 (0.59-0.83) with ciclesonide. CONCLUSIONS: In this matched cohort analysis, we observed that initiation of ICS with ciclesonide was associated with better 1-year asthma outcomes and fewer changes to therapy, despite data suggesting more difficult-to-control asthma. The median prescribed dose of ciclesonide was one-third that of fine-particle ICS.

		                        			PURPOSE: To evaluate the efficacy of sodium hypochlorite (1 : 10) and iodophor disinfectants on alginate impressions along with their effect on the survived bacterium count on the gypsum cast. MATERIALS AND METHODS: Four alginate impression on each dentate patients were made, of which Group I were not washed or disinfected, Group II impressions were merely washed with water, Group III were disinfected by spraying with sodium hypochlorite (1 : 10), Group IV were disinfected with iodophor (1 : 213). Gypsum cast (type III) were made from all the impression. Impressions and gypsum cast were swabbed in mid palatal region for bacterial culture. Bacterial colony counting done after 3 days of incubation at 37degrees C in blood agar media. The data obtained was analyzed by one way ANOVA test at a significant difference level of 0.05. RESULTS: Group I and Group II showed significantly more bacteria compared to Group III and Group IV. Bacterial colonies on the alginate impression and gypsum cast in group disinfected with Sodium hypochlorite (1 : 10) were 0.18, 0.82 respectively compared to group treated with iodophor (1 : 213). There was an increase in bacterial count on dental cast compared to source alginate impressions. CONCLUSION: Sodium hypochlorite (1 : 10) was found to be better disinfectant for alginate impression. There was an indication of increase in number of bacteria from alginate impression to making of dental cast. Additional gypsum cast disinfectant procedures need to be encouraged to completely eliminate cross infection to dental laboratory.

		                        			PURPOSE: The aim of this study was to evaluate the efficiency of manual polishing over autoglazed and overglazed porcelain and their effect on plaque accumulation. MATERIALS AND METHODS: Thirty-six porcelain discs were fabricated out of which 18 each was subjected for autoglazing and overglazing. Half surface of the discs was left intact; the remaining half was roughened with medium grit diamond bur. Roughened surfaces were repolished by porcelain polishing kits (Shofu, DFS, Eve). All the surfaces were evaluated by the perthometer and SEM. Six discs from each sample were placed in human volunteer's mouth for 72 hours to evaluate the plaque accumulation. Acquired data was subjected to ANOVA comparative evaluation. RESULTS: Roughened surfaces had average roughness value of 2.88+/-0.1935 microm. The repolished surfaces by porcelain correction kits Shofu, DFS and Eve, average roughness value reduced to 0.6250+/-0.1036, 0.9192+/-0.0953, 0.9017+/-0.1305 respectively. Autoglazed and overglazed surfaces showed the mean roughness value (Ra) of 0.4217+/-0.0685, 0.3450+/-0.0729. SEM study showed the improved surfaces when subjected for polishing. Plaque accumulation percentage was the highest on roughened surface (93.83+/-6.2552%), followed by porcelain discs polished by commercial kits. Autoglazed surfaces found to be the best surfaces with the least plaque accumulation (0.5237+/-0.4209%). CONCLUSION: All the polishing kits used in the study reduced the average roughness by approximately 77%. Corrected porcelain surfaces should ideally be reglazed, alternatively, polish the surfaces before final cementation.

		                        			Periodontal regenerative techniques have been proposed; however, the outcomes remain debatable. The present investigation assessed the regenerated cementum following enamel matrix derivative application in dehiscence-type defects. Buccal osseous dehiscences were surgically created on the maxillary cuspid, and the second and fourth premolars in five female beagle dogs. The treatment group (n = 15 sites) received the enamel matrix derived application, whereas the control groups (n = 15) did not. The dogs were sacrificed 4 months following treatment and the specimens were histologically and histometrically examined. The newly formed cementum was uneven in thickness and mineralization, overlapped the old cementum and exhibited functional orientation, cementocyte lacunae and collagen fibril bundles. Most of the histological specimens showed the presence of a gap between the newly formed cementum and the underlying dentin. Control sites did not exhibit any cementum formation. The present study concluded that newly formed cementum is of cellular type and exhibits multiple characteristics.
