Introduction: Dentinal Hypersensitivity (DH) presents as a short, intense pain emanating from exposed dentinal tubules. Many studies have concluded that mechanical, chemical or both factors increase the frequency of DH. Sealing of exposed dentinal tubule can be achieved with the use of Dental adhesives, restorations, Desensitising Agents (DA) and Lasers, each having their own mechanism of action. Aim: This clinical study was done to evaluate the efficacy of Hydroxy Methacrylate (HEMA) based DA and 980 nm diode laser in the treatment of DH. Materials and Methods: This two-arm parallel design split-mouth study was conducted on 30 adult patients attending the Dental Outpatient Clinic of Gandhi Medical College, Bhopal during the year December 2018 to January 2020 with clinically diagnosed high cervical DH (Charlie=3) occurring bilaterally in maxillary canine teeth. Scoring of baseline and postoperative DH was done utilising using Modified U.S. Public Health Service Criteria for DH Assessment. After recording the pretreatment baseline scores, mouth of each sample subject was divided bilaterally using split-mouth technique into Group A and Group B. The left side of patient’s mouth was designated as Group A in which a 10 W Diode Laser (980 nm) was used and right side of the patient’s mouth was classified as Group B, in which Shield Active (HEMA based) DA was used. The sensitivity score for both the groups was assessed immediately after application, after 24 hours, after seven days and after 21 days. Statistical Analysis was done by using Statistical Package for Social Sciences(SPSS) software version 22.0. Student’s t-test and repeated measures of ANOVA Test were applied. The p-value of less than 0.05 was considered statistically significant. Results: There was a statistically highly significant difference in sensitivity scores between both groups immediately after treatment p=0.038, after 24 hours, seven days and after 21 days. (p<0.001) depicting high efficacy of Diode lasers over DA. Repeated Measure of ANOVA was applied to find difference in mean score from baseline to 21 days. Immediately after application the results in Group A compared to baseline were statistically highly significant (p<0.001) and statistically significant in Group B (p<0.05). However, overall difference after 21 days compared to baseline were not significant in any group (p>0.05) depicting that the effect of both the desensitising therapies were not significant beyond 21 days in both the groups. Conclusion: Within the limits of this study, it can be concluded that both HEMA based DA and 980 nm diode laser were effective desensitisation treatment modalities for achieving immediate reduction of high cervical dentin hypersensitivity from baseline. Further, 980 nm Diode laser was found to be more efficacious and effective treatment option than HEMA based DA for treatment of DH.

Objectives: Consciousness during anesthesia is a non-reversible complication that may expose the patient to severe, long-term, emotional injuries and post-traumatic stress. Therefore, this study aimed to compare the effect of two methods of induction maintenance of anesthesia with thiopental sodium–remifentanil and propofol–alfentanil on consciousness during orthopedic surgery using a bispectral index (BIS) device.Methods: In this triple-blind clinical trial, 111 patients who underwent orthopedic surgery in Dezful Hospital (southwestern Iran) were investigated. Patients were randomly assigned into two groups: The intervention Group “A” received thiopental for the induction of and fentanyl for maintenance and intervention Group “B” received propofol and alfentanil. The patients underwent BIS monitoring before the end of surgery, and the BIS value was recorded. The Brice questionnaire was used to measure the consciousness. The data were analyzed using repeated Measure ANOVA test.Results: In the intervention Groups A and B, the mean BIS score was 63.71 and 60.62 in the first 5 min after surgery, reaching 65.25 and 67.73 60 min after surgery, respectively. The results of repeated measures ANOVA test showed that the mean BIS score was significantly different from the preoperative value (baseline) group during repeated measurements after surgery (5, 10, 15, 30, 40, and 60 min) (p<0.001). According to the Brice questionnaire, the prevalence of hearing loss during surgery showed a statistically significant difference between the two intervention Groups (A and B), and the incidence of hearing during surgery in intervention Group “B” was approximately 3 times higher than intervention Group “A” (odds ratio=3.22, 95% confidence interval: 1.32–7.79).Conclusion: The results indicate that none of the induction and maintenance pharmacologic methods have any superiority in terms of optimal depth of anesthesia in patients undergoing orthopedic surgery.

Abstract Background Colorectal cancer (CRC) is one of the leading causes of mortality and morbidity in the world. It is the third most common malignancy after lung & breast and the fourth leading cause of cancer-related deaths worldwide, accounting for approximately 1,400,000 new cases and about 700,000 deaths worldwide. Objectives The aim of this retrospective study is to compare the epidemiology, clinicopathologic features, different treatment modalities and outcomes regarding disease free survival (DFS), progression free survival (PFS) & overall survival (OS) of colorectal cancer disease between cases presented to Ain shams university hospital & to Luxor international hospital in 3 consecutive years. Patients and Methods The study is retrospective comparative study. Clinical oncology department in Ain Shams University Hospital and Luxor International Hospital. The data Collected from January 2013 to December 2015. This study analyzed hospital records of patients who diagnosed with colorectal cancer (CRC) and allocated into two groups: Group A: CRC patients presented to Ain-Shams University Hospital from January 2013 to December 2015, group B: CRC patients presented to Luxor International Hospital from January 2013 to December 2015. Results There was no statistically significant difference regarding age parameter in LIH when compared to ASU, but the study was consistent with higher incidence in patients who were aged more than forty- accounted about 70.5% in all CRC cases. Cases less than 40 years old, in group A were 35.2%, while in Group B were 23.5%. Even there was no statistically significant difference but it may be attributable to more westernization in Lower Egypt. Other explanation may be due to decreased low socioeconomic status and different lifestyle factors in more developing region what increase risk of colorectal cancer. Among our cases, there is no statistically significant difference regarding gender between the two hospitals. Both sexes almost were affected equally, females appeared to be at a slightly higher risk of developing CRC cancer with current prevalence 1.3:1 in ASU group, and 1.1:1 in LIH group. Conclusion The need to increase awareness about CRC in Egypt especially upper Egypt, is recommended. An awareness campaign should be performed to promote detection of CRC at its earliest and most curable stage by recognizing early symptoms and enabling early referrals for colonoscopy. Those at higher risk should be offered more intensive surveillance. Similarity of the data from different centers suggests that this is the picture of colorectal cancer typical of Egypt.

Background: Hepatic Encephalopathy is a syndrome observed in patients with liver cirrhosis. Various treatment modalities are in use for treatment of Porto Systemic Encephalopathy (PSE). Our study aimed to compare the efficacy of Rifaximin plus Lactulose vs.Lactulose alone in treating Hepatic Encephalopathy in local population. Materials & Methods: The study was conducted at a tertiary care hospital recruiting decompensated chronic liver disease(DCLD) patients with PSE. Using simple random sampling, patients were divided in two groups (A & B). Patients in group A received Lactulose plus Rifaximin while group B received Lactulose alone. Efficacy of treatment was assessed as return of the conscious level to pre-encephalopathy state as per clinical examination within 1 week after  start of the treatment. Results: A total of 124 patients were included in the study with each group (A & B) containing 62 patients. Frequency and percentage of efficacy among group A (Rifaximin plus Lactulose) verses group B (Lactulose alone) in treating Hepatic encephalopathy was 45 (72.6%) and 32 (51.6%) respectively. Conclusion: The study concluded that there is a significant difference in proportions of patients showing complete recovery from Hepatic encephalopathy treated with Lactulose plus Rifaximin as compared to Lactulose alone.

Abstract Objective The aim of this study was to assess the combined effect of erbium:yttrium-aluminum-garnet (Er:YAG) laser and mineralizing agents including casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and fluoride in improving the resistance of demineralized dentin at new demineralization process. Materials and Methods One hundred and twenty healthy dentin surfaces were prepared and demineralized using acidic solutions. Primary microhardness was measured (h1), and samples were randomly divided into six groups. Each group received a different protocol as follows: Group A (control group): no additional treatment, Group B: applying a fluoridated gel, Group C: applying a CPP-ACP-containing cream, Group D: irradiation of Er:YAG laser, Group E: irradiation of Er:YAG laser combined with the application of a fluoridated agent, and Group F: irradiation of Er:YAG laser combined with the application of CPP-ACP-containing cream. Microhardness values were measured afterward (h2). Then, all the groups were re-exposed to acidic solution, and microhardness was measured for the third time (h3). The microhardness data were analyzed using analysis of variance and Scheffe's post hoc test. Results Although application of mineralizing agents increased the microhardness of demineralized dentin in comparison with the control group, no significant difference was observed using two agents. Comparison of laser groups showed an increase in microhardness only after the irradiation of Er:YAG laser combined with the application of a fluoridated agent. Demineralizing process reduced the microhardness values in all the groups, but the application of a CPP-ACP agent caused the least reduction among the laser irradiated groups. Comparison of hardness changes at the beginning and end of the experiment did not show any significant differences between the groups. Conclusion Comparison of treatment modalities used in this study exhibited that fluoride had the greatest impact on dentin resistance. Laser irradiation on demineralized dentin did not increase the hardness or resistance to acidic attacks.

Introduction: Dentin hypersensitivity (DH) is the most common concern faced by most dentists in their day-to-day clinical practice. It is characterized by short-term, acute pain of variable intensity, which occurs in response to thermal, tactile, osmotic or chemical stimuli that cannot be attributed to any other type of defect or dental decay. Casein phosphopeptide varnish is a newer material used to treat dentinal hypersensitivity as it reduces demineralization and promotes remineralization. The aim of this study is to evaluate the efficacy of casein phosphopeptide based varnish (MI Varnish®) vs sodium fluoride-based varnish (Fluoritop SR® varnish) in treating dentinal hypersensitivity. Materials and methods: 40 subjects with a chief complaint of DH were divided into two equal groups, Group A (MI varnish®) and Group B (Fluoritop SR® varnish). Scaling and root planing was done and sensitivity was assessed using Visual analog scale (VAS) at baseline. On the 14th day, sensitivity was reassessed using VAS. The data obtained were subjected to statistical analysis using students‘t’ test. Results: On intragroup comparison, VAS scale showed a statistically significant difference for both the groups. On intergroup comparison, no statistical difference was found between both groups. (p = 0.139) Conclusions: From the above results, it can be concluded that MI varnish® and Fluoritop SR® varnish are equally efficacious in reducing dentinal hypersensitivity.

Background: Warts are very common disorders. Plane warts are caused by Human Papilloma Virus (HPV) occurring mostly in children and young adults. Among the treatment modalities, topical application of trichloroacetic acid (TCA) is age old. Potassium hydroxide (KOH) has a keratolytic effect on virus-infected cells. Aims: To compare the safety and efficacy of topical 10% KOH solution with 50% TCA solution in the treatment of plane warts. Materials and Methods: Sixty-four consecutive patients with plane warts were randomly assigned into two groups of thirty-two patients. Group A received 10% KOH solution and group B received 50% TCA solution once weekly until the complete clearance of warts in a maximum period of 12 weeks. Results: In group under treatment with 10% KOH, 24 patients (75.0%) complete response, 5 patients (15.6%) moderate response, 2 patients (6.3%) mild response, and 1 patient (3.1%) had no response. In group under treatment with 50% TCA, 28 patients (87.5%) showed complete response, 2 patients (6.3%) moderate response, 2 patients (6.3%) mild response. Statistically no significant difference was found between the therapeutic response to 10% KOH and 50% TCA (P=0.41). Conclusion: 10% KOH was found to be equally effective in the treatment of plane warts compared to 50% TCA with the advantage of fewer side effects.

<p><strong>Background</strong>: Palmoplantar keratoderma is a heterogenous group of disorders, hereditary or acquired, characterized by thickening of palms and soles. Though it is not a life-threatening condition, it affects individual’s quality of life. As treatment of keratoderma has always been troublesome, upgraded treatment modalities which improves keratoderma efficiently are always encouraged.</p><p><strong>Methods</strong>: In this randomized controlled study, patients of plantar keratoderma of age group of 18-65 years were randomly divided in group A and group B. In group A, iontophoresis combined sodium salicylate was offered to patients twice weekly for 8 weeks of duration, during which DC current was supplied at 5-15 mA for 10 min of duration. Whereas, in group B patients applied topical salicylic acid 12% ointment at home twice a day for 8 weeks.</p><p><strong>Results</strong>: Our study of 70 patients of keratoderma, revealed diffuse (94%) pattern of involvement with female preponderance (55.7%) and occupation wise, most common among laborers (54.2%) followed by housewives (27.1%). Statistically significant number of patients showed reduction in severity grading of parameters, in both groups at end of 8 weeks. Same way, mean values of parameter grading significantly reduced at 8 weeks in both the groups. But intergroup values showed no significant difference. Mean EASI (Eczema Area Severity Index) score showed statistically significant reduction in group B as compared to group A at 8<sup>th</sup> week. Percentage of reduction of EASI score was also significantly higher in group B at end of treatment.</p><p><strong>Conclusions:</strong> Here both treatment modalities are safe and effective, topical being slightly more efficacious than iontophoresis. So, we can conclude that no additional privilege of drug delivery through iontophoresis.</p>

Background: Major side effects after endovenous laser ablation (EVLA) are pain and bruising. Low temperature of the tumescence fluid might cause additional venous constriction and a cooling effect around the vein. The aim of this study was to show outcome and side effects after EVLA of incompetent great saphenous veins (GSV) with a 1470 nm Diode laser (Ceralas E, biolitec) using cold or warm tumescence fluid for anaesthesia. Patients and methods: Between August and November 2007, 85 consecutive patients (85 legs) with an incompetent GSV were treated by EVLA. The patients were randomized in two groups. In 42 patients (Group A) a warm (37 °C) and in 43 patients (Group B) a cold (5 °C) tumescence fluid (TF) was used for local anaesthesia in the track of GSV. All patients were re-examined after 1, 10 and 30 days clinically and by duplex for complications and occlusion in the treated vein segment. Patient’s satisfaction was assessed on a 0 to 4 points scale. Results: In each group one patient was lost to follow-up. There was no significant difference concerning gender, age, C of CEAP, BMI or diameter of the treated vein. In Group A a mean of 462 ml TF and in Group B a mean of 428 ml TF were used. In Group A the mean LEED (average linear endovenous energy density) was 114 J / cm and in Group B 115 J / cm. In both groups occlusion of the treated veins was achieved for all patients. The diameter of the GSV at 3 cm below the sapheno-femoral junction shrunk from 1.0 to 0.7 cm in both groups. The modified CEAP clinical score improved in Group A from 2.9 to 0.7 (mean value) and in Group B from 3.0 to 1.1. The mean pain score on a scale from 0 to 4 during day 2 to day 10 was 1.2 in Group A and 1.0 in Group B. At this time patients in Group A took a mean of 3.4 and in Group B 1.7 analgetic tablets. Ecchymoses were rare in both groups (4 in Group A, 7 in Group B). Conclusions: In this prospective randomized comparative study the temperature of the tumescence fluid did not influence the occlusion rate when a high LEED was used. In both groups pain and ecchymoses are less frequent in this study with a 1470 nm diode laser than reported in studies with 810-980 nm systems. Cold tumescence fluid reduced pain slightly and reduced the intake of analgetics significantly.

Abstract Background This study aims to investigate the influence of different dentin pretreatment procedures on the resulting abrasive dentin wear. Methods Two groups (A, B) of 60 dentin samples each were prepared. Group A was brushed with an abrasive slurry (RDA = 85) and group B with a different abrasive slurry (RDA = 174). Four subgroups in each group (n = 15) were created (A1–A4) and (B1–B4). The subgroups were pretreated as follows: A1 + B1 with 1200-grit grinding paper, A2 + B2 with 1200- and 2000-grit papers, A3 + B3 with 1200-, 2000-, and 4000-grit papers, A4 + B4 with 1200-, 2000-, 4000-grit papers and with 1000 brushing strokes with a slurry of Elmex toothpaste. All samples were brushed for 25 min at 120 strokes/min. Abrasive dentin wear was measured for each sample profilometrically and the subgroups were compared with each other within the same group. Repeated measures one-way ANOVA was conducted to compare the subgroups and pairwise contrasts were estimated for multiple testing according to Tukey (α = 0.05). Results The resulting abrasive dentin wear in group A ranged between 15.3 ± 3.4 µm and 17.3 ± 5.5 µm and between 20.3 ± 6.8 µm and 22.5 ± 2.6 µm in group B. No statistically significant difference was noticed between any subgroups within the same group (p ˃ 0.05). Conclusions Different dentin pretreatment procedures do not affect the resulting abrasive dentin wear independent of the RDA value of the employed abrasive slurry.

Background and Objective: Ardhavabhedaka (migraine without aura) is characterized by severe tearing, pricking and piercing pain in one half of the head and giddiness which develops suddenly after ten days or a fortnight. Based on signs and symptoms it may correlate with migraine characterized by half sided head-ache associated with nausea, vomiting, photophobia and phonophobia. The current line of management for migraine advocates the use of analgesics and antiemetics, vasoconstrictors, sumatriptan, topiramate, flunar-izine, Propranolol. Ayurveda emphasizes various treatment modalities of Ardhavabhedaka, includes both Shodhana and Shamana. Vidangadi avapeedana Nasya and Vidangadi arka (distillate) Nasya have been mentioned for ardhavabhedaka chikitsa. Arka is the essence of the drug; possesses laghu, ushna, kaphavatahara, increased potency, more shelf life, easy absorption and act fast. Materials and Methods: 20 patients of Group A were treated with Vidangadi Arka Nasya and Group B 20 patients were treated with Vidangadi Avapeedana Nasya (each nostril 6 drops for 7 days). Results: The data of both the groups were collected according to the objective and subjective Parameters and analyzed using repeated measures of ANOVA, Bonferroni test, and Mann- Whitney U Test. The efficacy was statistically highly significant with-in the group at P <0.001and statistically insignificant between the group at P >0.05 among all the parame-ters. Interpretation and Conclusion: Study can be concluded that patients treated with Vidangadi Arka and Avapeedana Nasya showed not much difference in the results statistically, clinically group A showed better results than group B.
