To assess the role of prefabricated SFI-Bar in peri-implant bone loss around immediately axially loaded and straight implants. This study comprised of 40 complete denture wearer patients who received two axially parallel implants connected by SFI-Bars in group I and two 15° mesially tilted implants connected by SFI-Bars in group II. Peri- implant bone loss (PiBL) was measured at 1 year, 2 years and 3 years. The mean PiBL at 1 year in group I was 0.21 mm and I group II was 0.22, at 2 years in group I was 0.26 mm and in group II was 0.23 mm and at 3 years, in group I was 0.29 mm and in group II was 0.34 mm. The difference was significant at 3 years (P< 0.05). The mean mesial PIBL at 1year in group I was 0.18 mm, in group II was 0.20 mm, at 2 years in group I was 0.19 mm and in group II was 0.07 mm and at 3 years, in group I was 0.25 mm and in group II was 0.29 mm. The difference found to be significant in each time duration in both groups (P< 0.05).The mean distal PIBL at 1 year in group I was 0.23 mm, in group II was 0.22 mm, at 2 years in group I was 0.33 mm and in group II was 0.39 mm and at 3 years, in group I was 0.34 mm and in group II was 0.39 mm. The difference found to be significant at 2 and 3 years in both groups (P< 0.05). Authors found that mandibular overdentures retained with Prefabricated SFI-Bar with axial and straight inserted implants may be useful in patients with reduced bone height.

In this study, genotoxic effects of repeated sevoflurane anaesthesia were investigated in rabbits with or without antioxidant supplementation. Twenty-one New Zealand male rabbits were included in the study and randomized into three groups as: placebo treated (Group I), vitamin E supplemented (Group II) and selenium supplemented (Group III). Vitamin E and selenium were given intraperitoneally for 15 days before anaesthesia treatment. Anaesthesia was administered using 3% sevoflurane in 4 L/min oxygen for a 3-hour period and continued for 3 days. Blood samples were collected before anaesthesia (Sample 1), after the first, second and third days of sevoflurane administration (Sample 2, Sample 3 and Sample 4 respectively) and the last samples were taken 5 days after the last sevoflurane administration (Sample 5). Genotoxic damage was examined using the comet assay. The degree of damage is assessed by grading the cells into three categories of no migration (NM), low migration (LM) and high migration (HM) depending on the fraction of DNA pulled out into the tail under the influence of the electric field. The number of comets in each sample was calculated (1 × number of comets in category NM + 2 × number of comets in category LM + 3 ×number of comets in category HM) and expressed as the total comet score (TCS), which summarizes the damage frequencies. In Group I, a significant increase in the mean TCSs was observed for Samples 3 and 4 as compared with Sample 1. However, there were no significant differences between Samples 1, 2 and 5. The mean TCS of Sample 4 was significantly higher than Sample 1, 2 and 3 in Group II. Group III demonstrated no significant mean TCSs for any experimental conditions. Statistical differences were also observed between the groups with significant P values. This experimental study points out the presence of DNA damage with repeated sevoflurane anaesthesia and the genoprotective role of antioxidant supplementation on DNA damage in mononuclear leukocytes of rabbits by highly sensitive comet assay.

The monthly wool growth of three groups of rams was studied at Beltsville, Maryland. Group I received natural daylight (at 38° 53' N.) and was shorn monthly. Group II had a 7:17 hours of daylight to hours of darkness rhythm and was shorn every 6 months, once in winter and once in summer. Group III received natural daylight and was likewise shorn every 6 months. The rams of all groups produced more wool in summer than in winter. This difference was significant (P<0.001). The mean body weight and food intake were both greater in the winter months, which indicated that the seasonal rhythm of wool growth was not a consequence of poorer feeding in winter. The rams which were shorn monthly (group I) grew considerably more wool than the other two groups, but the difference was not statistically significant. The short-day treatment of group II did not increase the annual wool production nor decrease the seasonal rhythm of wool growth. The balance of evidence from this and other experiments indicates that temperature rather than light controls the seasonal rhythm of wool growth.

Background: Nontraumatic musculoskeletal disorders are the main reason for presentation to the emergency department with Rachialgia being the most common reason to request medical assessment among them. Methods: This was a prospective, randomized, parallel group open labelled study conducted in a district level tertiary care hospital attached to a medical teaching institute. Patients were randomized into two groups. Group I (63 patients) received tablet tramadol 50 mg twice daily orally and group II (63 patients) received tablet tapentadol 50 mg twice daily orally.Results: The mean age of the patients of group I was 40.6±9.6 years and in the group II was 42.7±10.6 years. A total of 61 males participated in the study of which 31 males were enrolled in group I and 30 in group II while 65 females participated in the study of which 32 females were enrolled in group I and 33 in group II. The mean reduction of pain intensity VAS score at the end of 4 weeks from baseline in group I and group II were 34.57 and 37.55 respectively. The difference in the mean reduction of pain intensity VAS between the two groups was not statistically significant.Conclusions: We conclude that both the drugs show significant reduction in the pain intensity in moderate to severe CLBP patients. Tapentadol is as efficacious as tramadol in moderate to severe CLBP. However, tapentadol is better tolerated than tramadol.

This study analyzes the marginal bone loss (MBL) among dental implants characterized with non-threaded collar design (NT) when compared to the more classic micro-threaded collar design (MC) as such might reflect the future dentogengival esthetics, implant metal show, and mucositis. A total of 112 patients who received 311 implants have been included in the study and analyzed for their postoperative MBL using sequential periapical radiographs. The prevalence of postoperative peri-implant mucositis was recorded as well. The periapical radiographic comparison was performed between the immediate postoperative record and at the 24-month recall visit. Among the 311 implants, 124 (39.9%) had NT implants, and 187 (60.1%) had MC implants. Out of the 112 patients, 37 (44.6%) were females, and 10 (34.5%) were males included in the NT group. In contrast, 46 (55.4%) females and 19 (65.5%) males were in the MC group. The mean age among the two groups was 41.43 ± 15.900 and 46.68 ± 16.070, respectively. In contrast, the mean MBL among the groups were 0.544 ± 0.7129 and 0.061 ± 0.2648, respectively. The change in MBL was not positively correlated with gender (p-value = 0.154) or age (p-value = 0.115) in both groups. However, there was a significant difference (p-value = 0.001, X2 = 62.796, Df = 4) of MBL between the two implant systems themselves. The MBL was higher in people implanted with the NT system when compared to MC. Therefore, the MC implant system can be a better choice for marginal bone preservation, especially in restoring esthetically demanding areas in the mouth.

Renal involvement has been well documented in patients with hepatosplenic schistosomiasis and in patients with prolonged salmonella bacteremia (PSB). Whether there is a specific renal lesion related to PSB or the chronic bacterial infection aggravates a pre-existing schistosomal glomerulopathy has been a matter of controversy. To analyze the clinical manifestations and histopathological findings of the renal involvement, 8 patients with hepatosplenic schistosomiasis and PSB (group I) were compared with 8 patients with schistosomal glomerulopathy (group II) matched by sex and glomerular disease. The mean age in group I was 17.7 years. All patients presented with hematuria, in 4 cases associated with non-nephrotic proteinuria. In group II the mean age was 23 years; nephrotic syndrome was the clinical presentation in 7 of the 8 patients in the group. All patients in group I experienced remission of the clinical and laboratory abnormalities as the salmonella infection was cured; in group II the patients had persistent, steroid-resistant, nephrotic syndrome. On histological examination, no difference was noted between the two groups, except for pronounced glomerular hypercellularity and interstitial mononuclear cell infiltration in group I. These observations strongly suggest that PSB exacerbates a pre-existing sub-clinical schistosomal glomerulopathy by the addition of active lesions directly related to the prolonged bacteremia

Background: Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of death universally. The present study was conducted to assess LA volume index (LAVI) in the patients with ACS in adults.Subjects and Methods: The present study was conducted on120 adult patients diagnosed with ACS of both genders in narayana medical college hospital from May 2016 toOctober 2016. Patients were divided into 2 groups of 60 each. Group I patients had LAVI > 34 ml/m2 and group II patients had LAVI ≤ 34 ml/m2. The LV systolic function was analyzed by Simpson’s disc volumetric method. The LAV was assessed by the biplane area‑length method from apical 4‑chamber and 2‑chamber views.Results: The mean BMI in group I patients was 26.7 kg/m2 and in group II was 26.1 kg/m2, AW STEMI in group I was seen in 30 patients and in group II in 32, IW + PW STEMI in 6 and 4 patients in both groups respectively, IW STEMI in 5 and 4 patients respectively, NSTEMI in 4 and 3 patients respectively and UA in 15 and 17 patients respectively. Risk factors were diabetes mellitus in 32    and 27 patients respectively, hypertension in 41 and 40 patients respectively, smoking in 43 and 38 patients respectively, alcohol in 30 and 35 patients respectively and positive family history in 12 and 16 patients respectively. The difference was non- significant (P> 0.05). The mean LAVI at admission in group I was 38.1 and in group II was 27.2, after 1 month was 40.2 and 28.1 in both groups, after 6 months was 39.1 and 27.9 in both groups and after 12 months was 42.7 and 25.3 in both groups respectively. The difference was significant (P< 0.05).Conclusion:Authors conclude that LAVI was found to be the independent predictor of mortality than left ventricular ejection fraction on multivariate regression analysis. Common risk factors in patients with ACS were diabetes mellitus, hypertension, smoking, alcoholism and positive family history. Patients with LAVI of value >34 ml/m2 were associated with increased comorbidities.

Coronary artery disease (CAD) is the most common cause of mortality and morbidity all over the world. It is also becoming a significant burden on healthcare service in Bangladesh. Atherosclerosis is the main pathology behind coronary artery disease. Endothelial dysfunction plays a crucial role in the process of atherosclerosis. Microalbuminuria (MA) is a reliable marker of endothelial dysfunction. This is why microalbuminuria is recognized as a simple marker of atherogenic milieu It was a cross sectional analytical study carried out in the department of Cardiology, Dhaka Medical College Hospital, Dhaka during the period of May, 2013 to April, 2014. After ethical consideration a total of 120 patients with IHD admitted in the department of Cardiology who fulfilled the inclusion and exclusion criteria and underwent coronary angiogram were taken as sampling population by purposive sampling. 1st morning spot urine sample was taken for measurement of ACR.Microalbumnuria was measured by rate nephelometry using Behring protein analyzer. All the study subjects were placed into two groups according to ACR value (group I- positive urinary ACR >30 mg/g & group II-Normal urinary ACR <30 mg/g). Angiographic severity of coronary artery disease was assessed by vessel score and stenosis score. Age and sex distribution of the subjects in two groups with MA and without MA were similar. No significant difference was observed between two groups with regard to smoking, dyslipidaemia, hypertension and family history of IHD. Prevalence of diabetes mellitus was significantly more in subjects with MA than without MA (60% vs 33.9%, p=0.006). All 40 patients of group I had significant CAD. 57(71.2%) patients of group II had significant CAD and 23(28.8%) patients had no significant CAD. The difference was highly significant (p<0.001). Single vessel involvement was significantly more frequent in subjects of group II than group I (35.0% vs15.0%, p=0.022) Double vessel involvement was more in group I than group II, but the difference was not statistically significant (36.8% vs 32.40%,p=0.641).Triple vessel involvement was significantly more frequent in subjects of group I than group II (50.0% vs10.7%, p<0.001). The mean stenosis score of group I was significantly higher than group II (95% CI 4.966 to 2.809, p<0.001). The mean ±SD total coronary vessel score of group I was 16.60±4.75 with a range of 7.0-21.0 and mean ±SD total coronary vessel score of group II was 8.26±6.24 with a range of 0.0-21.0. The mean total score of group I wassignificantly higher than group II (95% CI 10.558 to 6.117, p<0.001). Patient with microalbuminuria has more extensive and complex angiographic coronary artery disease compared to those without microalbuminuria.University Heart Journal Vol. 10, No. 1, January 2014; 18-22
