Xenogeneic Collagen Matrix Versus Free Gingival Graft for Augmenting Peri-Implant Keratinized Mucosa Around Dental Implants: A Systematic Review and Meta-Analysis.

OBJECTIVES: There is a growing evidence to suggest augmenting peri-implant keratinized mucosa in the presence of ≤ 2 mm of keratinized mucosa. However, the most appropriate surgical technique and augmentation materials have yet to be defined. The aim of this systematic review and meta-analyses was to evaluate the clinical and patient-reported outcomes of augmenting keratinized mucosa around implants using free gingival graft (FGG) versus xenogeneic collagen matrix (XCM) before commencing prosthetic implant treatment. MATERIAL AND METHODS: Electronic databases were searched to identify observational studies comparing implant sites augmented with FGG to those augmented with XCM. The risk of bias was assessed using the Cochrane Collaboration's Risk of Bias tool. RESULTS: Six studies with 174 participants were included in the present review. Of these, 87 participants had FGG, whereas the remaining participants had XCM. At 6 months, sites augmented with FGG were associated with less changes in the gained width of peri-implant keratinized mucosa compared to those augmented with XCM (mean difference 1.06; 95% confidence interval -0.01 to 2.13; p = 0.05). The difference, however, was marginally significant. The difference between the two groups in changes in thickness of peri-implant keratinized mucosa at 6 months was statistically significantly in favor of FGG. On the other hand, XCM had significantly shorter surgical time, lower postoperative pain score, and higher color match compared to FGG. CONCLUSIONS: Within the limitation of this review, the augmentation of keratinized mucosa using FGG before the placement of the final prosthesis may have short-term positive effects on soft tissue thickness. XCM might be considered in aesthetically demanding implant sites and where patient comfort or shorter surgical time is a priority. The evidence support, however, is of low to moderate certainty; therefore, further studies are needed to support the findings of the present review.

Alveolar ridge preservation versus early implant placement in single non-molar sites: A systematic review and meta-analysis.

OBJECTIVES: The aim of this systematic review and meta-analyses was to evaluate the outcomes of alveolar ridge preservation (ARP) following extraction of non-molar teeth in comparison to early implant placement (EIP) in terms of clinical and radiographic changes, need for additional augmentation at the time of implant placement, patient-reported outcomes, and implant failure rate. METHODS: Electronic databases were searched to identify randomized and non-randomized studies that compared ARP to EIP. The risk of bias was assessed using the Cochrane Collaboration's Risk of Bias tool. Data were analyzed using a statistical software program. RESULTS: A total of 106 studies were identified, of which five studies with 198 non-molar extraction sockets in 198 participants were included. Overall meta-analysis showed significant differences in changes in midfacial mucosal margin (mean difference (MD) -0.09; 95% confidence interval (CI) -0.17 to -0.01; p = .03) and ridge width (MD -1.70; 95% CI -3.19 to -0.20; p = .03) in favor of ARP. The use of ARP was also associated with less need for additional augmentation at implant placement, but the difference was not statistically significant. CONCLUSIONS: Within the limitation of this review, ARP following extraction of non-molar teeth has short-term positive effects on soft tissue contour, mucosal margin and thickness, and alveolar ridge width and height. It can also simplify future implant treatment by minimizing the need for additional augmentation.

Airflowing as an adjunctive treatment for periodontitis: A randomized controlled trial.

BACKGOUND: The aim of this randomized controlled trial was to assess clinical and patient-reported outcomes of subgingival instrumentation (SI) with adjunctive use of erythritol airflowing (EAF) compared to SI alone in the treatment of periodontitis. METHODS: Twenty-six participants with Stage III/IV periodontitis requiring nonsurgical periodontal treatment were randomly allocated into two treatment groups: SI with EAF or SI alone. Clinical parameters of percentage of probing pocket depths (PPDs) of ≥5 mm, full mouth bleeding and plaque scores (FMBS and FMPS), and PPD values were recorded at baseline, and at 3 and 6 months posttreatment. A visual analogue scale was used to evaluate postoperative participants' perception of pain, swelling, bleeding, bruising, and root sensitivity. The impact of periodontal treatment on quality of life was assessed using the General Oral Health Assessment Index (GOHAI) at six months. RESULTS: A total of 26 participants with Stage III/IV periodontitis completed the 6-month follow-up. SI with or without EAF resulted in a statistically significant reductions in the FMBS, FMPS, PPDs, and percentage of PPDs of ≥5 mm at the 3- and 6-month follow-up visits. There was no statistically significant difference between the two treatment groups for any time interval. Participants receiving SI/EAF exhibited a higher reduction in FMBS compared to those in SI alone group at 3 (SI/EAF: 19.4 ± 11.9, SI alone: 30.1 ± 20.5; P = 0.12) and 6 months (SI/EAF: 14.3 ± 9.6, SI alone: 24.5 ± 18.2; P = 0.09). A lower percentage of sites with deep PPDs (≥5 mm) was also noted amongst participants in the SI/EAF group compared to SI alone at 3 months (SI/EAF: 14.3 ± 14.1, SI alone: 19.2 ± 20.3; P = 0.48) and 6 months (SI/EAF: 8.3 ± 10.0, SI alone: 15.4 ± 17.4; P = 0.22). Patient-reported outcomes showed no significant differences between the two treatment groups, except in the psychosocial domain of the GOHAI at 6 months favoring the SI/EAF group (P = 0.03). CONCLUSIONS: Within the limitations of the study, the adjunctive use of EAF in addition to SI in the treatment of Stage III/IV periodontitis did not result in a significant improvement in clinical parameters. Limited improvement in the QoL with EAF could be achieved.

Quantity and Size of Titanium Particles Released from Different Mechanical Decontamination Procedures on Titanium Discs: An In Vitro Study.

Complications such as peri-implantitis could ultimately affect the survival of a dental implant. The prevention and treatment of peri-implant diseases require managing bacterial biofilm and controlling environmental risks, including the presence of pro-inflammatory titanium (Ti) particles in the peri-implant niche. Objectives included the evaluation of the size and quantity of Ti particles released from moderately roughened Ti surfaces during common mechanical surface decontamination methods. One hundred and forty moderately roughened Ti discs were divided into seven groups (n = 20 per group); six groups received mechanical decontamination procedures (ultrasonic scaling (US) with a metal tip and poly-ether-ketone (PEEK) under low and medium power settings, air-polishing with erythritol powder, and Ti brush), and the control group underwent air-water spray using a dental triplex. The rinsing solution was collected for Ti mass analysis using inductively coupled plasma mass spectrometry (ICPMS), as well as for Ti particle size and count analysis under scanning electron microscopy (SEM) with energy-dispersive spectroscopy (EDS). US metal tip instrumentation generated 34.00 ± 12.54 µg and 34.44 ± 6.08 µg of Ti under low and medium power settings, respectively. This amount of Ti generation was significantly higher than other instrumentation methods. The mean Ti particle size of the US groups ranged from 0.89 ± 0.27 µm to 1.25 ± 0.24 µm. No statistically significant difference was found in the particle size among US groups and Ti brush group (1.05 ± 0.11 µm), except for US with the PEEK tip, where a significantly smaller mean particle diameter was found at the low power setting (0.89 ± 0.27 µm). Mechanical instrumentation can produce Ti particulates and modify the implant surfaces. US using a metal tip generated the highest amount of Ti with smaller Ti size particles compared to all other commonly used mechanical surface instrumentations. The EDS analysis confirmed Ti in PEEK US tips. It can be suggested that deterioration from the PEEK US tip and Ti brush, as observed under SEM, is an additional source of Ti release during Ti surface decontamination.

Monolithic Zirconia Single Crowns Supported by Narrow or Standard Diameter Titanium-zirconium Implants in Posterior Sites: One-year Results of a Randomized Controlled Trial.

The replacement of missing teeth with implant-supported prostheses has become a standard treatment option with reliable long-term outcomes in various clinical indications.1-6 The implant-supported single crowns, in particular, presented the most favorable outcome with a survival rate of 89.5% to 96% over a 10-year period.5,6 A notable prosthetic maintenance requirement, however, was reported irrespective of the prosthetic material used for the crown construction.1,7 Metal-ceramic restorations have been considered the gold standard when replacing single or multiple missing teeth with implant-supported fixed dental prostheses.8 A systematic review of 4363 metal-ceramic implant-supported single crowns in the anterior and posterior region reported an impressive survival rate of 98.3% over five years.9 Yet, the biologic and prosthetic complications associated with these restorations were substantial with a rate of 13.5%. In the posterior region, a recent systematic review of short-term randomized controlled trials10 reported a survival rate of 99.1% for metal-ceramic implant-supported single crowns. The reported prosthetic complications, mainly ceramic chipping, were also notable with an incidence rate of 7.6%.mIn recent years, the introduction of high-strength all-ceramic materials as well as digitaldesign and manufacturing processes, has allowed faster fabrication of more esthetic and cost effective restorations.11 Zirconia-based fixed dental prostheses on teeth and implants are now increasingly used and show 5-year cumulative survival rates of 89.4 to 100%.12 These restorations are typically made up of a zirconia framework that is veneered with a layer of glass ceramic to impart translucency for enhanced esthetics.13 However, chipping of the ceramic layer has been a lingering issue, shifting the attention toward the use of full anatomic monolithic zirconia restorations.14,15 Replacement of missing teeth with dental implants in posterior ridges with limited bone width can be surgically challenging and the notion of narrow diameter implants has been suggested.16,17 These implants were thought to offer potential advantages in terms of costeffectiveness and surgical morbidity.18,19 The literature, however, remains controversial on treatment outcomes with narrow diameter implants, particularly in posterior sites.19-21 When single tooth replacement with monolithic zirconia implant-supported single crowns in posterior sites are considered, only short to medium-term outcomes are available.22-26 The survival rates and clinical performances reported in these studies were variable. Crown survival rates between 84% and 100% were demonstrated over an observation time of one to three years, while the prosthetic complications were between 0% to 14%. In three studies,22,23,25 standard diameter titanium implants were used in premolar and molar sites to support the single crowns. The remaining two studies by Mühlemann et al. (2020) and Zumstein et al. (2023) reported the one-year and three-year outcomes, respectively, of the same cohort. In these studies, narrow titanium-zirconium (TiZr) implants of 3.3 mm diameter were exclusively utilized in molar sites. The implant and crown survival rates reported at one and three years were 97.4% and 84%, respectively. The lower survival rate observed in the report of Zumstein et al. (2023) resulted from fracture of five implants and the subsequent loss of their respective crowns. Aside from these two reports, no other information on the outcomes of monolithic zirconia single crowns supported by narrow diameter TiZr implants in posterior sites are available. The validity of this treatment, therefore, needs further investigation with well-designed clinical trials. Hence, a randomized controlled trial was undertaken to assess various implant, prosthetic, and patient-reported outcomes of monolithic zirconia single crowns supported by either narrow or standard diameter titanium-zirconium (TiZr) implants in posterior sites. The present report focuses on the one-year prosthetic results.

Diode laser as an adjunctive treatment for periodontitis: Arandomized controlled trial.

OBJECTIVE: The aim of this randomized controlled trial was to assess clinical and patient reported outcomes of subgingival instrumentation (SI) with adjunctive use of diode laser (DL) versus SI alone in the treatment of periodontitis. METHODS: Participants requiring non-surgical periodontal treatment were randomly allocated into two treatment groups: SI with DL or SI alone. Clinical parameters [full mouth bleeding and plaque scores (FMBS and FMPS), probing pocket depth and clinical attachment level] were recorded at baseline, three and 6 months post-treatment. Visual analogue scale was used to evaluate postoperative participants' perception of pain, swelling, bleeding, bruising and root sensitivity. The impact of periodontal treatment on quality of life was assessed using the General Oral Health Assessment Index (GOHAI) at 6 months. RESULTS: A total of 22 participants with stage III/IV periodontitis completed the 6-month follow-up. SI with or without DL resulted in statistically significant reduction in FMBS, FMPS, PPDs, and percentage of PPDs of ≥5 mm at 3- and 6-month follow-up visits (p = 0.001 to <0.001). The participants in SI/DL group had a greater reduction in the percentage of deep PPDs (≥5 mm) compared to those receiving SI alone, but statistically significant differences between the two groups were not observed (16.40 ± 9.57 vs. 32.50 ± 38.76 at 3 months and 7.20 ± 6.86 vs. 19.50 ± 35.06 at 6 months). The difference in the mean total GOHAI scores was not statistically significant at 6 months with total GOHAI scores of 7.25 ± 2.45 and 5.40 ± 3.06 for SI and SI/DL groups, respectively. CONCLUSION: Within the limitations of this study, the use of DL as an adjunct to SI in the treatment of stage III/IV periodontitis did not produce significant additional improvement in clinical parameters or patient reported outcomes in the 6-month observation period.

Changes in oral home care and smoking habits during COVID-19 pandemic: A cross-sectional study.

OBJECTIVES: The coronavirus disease-19 (COVID-19) pandemic has caused disruption in the health behavior in many aspects of life. While hand hygiene was promoted as one of the precautionary measures to mitigate and contain COVID-19, oral health and smoking might have received less attention in the media campaigns. The aim of this study was to examine health behavioral changes in terms of oral home care habits, smoking, and perception of dental care during the COVID-19 pandemic. MATERIAL AND METHODS: An online survey was designed to assess oral home care, smoking habits, and attitude toward dental services of participants aged 18 years and older. The data were collected between September and November 2021. The strength of association between changes in oral home care habits, smoking, and attitude toward invasive/long dental procedures and each variable was measured by χ2 analysis. Estimates of relative risk were also calculated for all variables. Predictors of avoiding dental procedures were estimated by a binary logistic regression. RESULTS: A total of 532 participants, based in the United Arab Emirates, took part in this online survey with a response rate of 88.7%. The age of the participants ranged between 18 and 67 with mean age of 34.9 ± 9.0 years. The majority of the participants have adopted changes in their routine oral home care habits, with 82.1% of them changing the toothbrush more frequently. Participants who changed their oral home care habits were more likely to have received sufficient information on the importance of maintaining oral health. Likewise, the changes in smoking habits were significantly associated with receiving information on the relationship between smoking and the severity of the COVID-19 (p < 0.001). CONCLUSIONS: The findings showed that positive behavior toward oral home care and smoking was noticed during the pandemic particularly when public receives sufficient and up-to-date information.

A case study evaluating the effect of clustering, publication bias, and heterogeneity on the meta-analysis estimates in implant dentistry.

Meta-analyses may provide imprecise estimates when important meta-analysis parameters are not considered during the synthesis. The aim of this case study was to highlight the influence of meta-analysis parameters that can affect reported estimates using as an example pre-existing meta-analyses on the association between implant survival and sinus membrane perforation. PubMed was searched on 7 July 2021 for meta-analyses comparing implant failure in perforated and non-perforated sinus membranes. Primary studies identified in these meta-analyses were combined in a new random-effects model with odds ratios (ORs), confidence intervals (CIs), and prediction intervals reported. Using this new meta-analysis, further meta-analyses were then undertaken considering the clinical, methodological, and statistical heterogeneity of the primary studies, publication bias, and clustering effects. The meta-analyses with the greatest number and more homogeneous studies provided lower odds of implant failure in non-perforated sites (OR 0.49, 95 % CI = [0.26, 0.92]). However, when considering heterogeneity, publication bias, and clustering (number of implants), the confidence in these results was reduced. Interpretation of estimates reported in systematic reviews can vary depending on the assumptions made in the meta-analysis. Users of these analyses need to carefully consider the impact of heterogeneity, publication bias, and clustering, which can affect the size, direction, and interpretation of the reported estimates.

Review of the Most Cited Patient-Reported Outcome Measure (PROM) Studies Published in the Neurospine Surgical Literature.

Patient-reported outcome measures (PROMs) are validated tools that are widely utilized in research and patient care. Their diversity, quality, and application remain matters of peak research interest. This article is a review of the PROMs that were utilized in high-impact publications in the neurospine surgical literature. The 50 most cited articles on the subject were selected and analysed. Most (42 articles) were published in spine journals and, in particular, in the journal Spine (Phila Pa 1976) (28 articles). A total of 34 PROMs were utilized, of which 24 were used only once in single studies. The four most common PROMs were Scoliosis Research Society-22 (SRS-22) (15 articles), Short Form-12 and Short Form-36 (SF-12 and SF-36) (11 articles), Ronald-Morris Disability Questionnaire (RMDQ) (nine articles), and Oswestry Disability Index (ODI) (five articles). Nineteen articles focused on validating translated versions of 11 PROMs to other languages. The languages that had the maximal number of tools translated to amongst the highly cited articles were Italian (six tools), Portuguese (four tools), German (three tools), and Japanese (three tools). The most common diagnoses and the PROMs used for them were back pain and cervical spine disorder (SF-12 and SF-36 (nine articles), RMDQ (eight articles), and ODI (five articles)), and idiopathic scoliosis (SRS-22) (14 articles)). The median (range) article citation number was 137 (78-675). The four most cited PROMs were SRS-22 (2,869), SF-12 and SF-36 (2,558), RMDQ (1,456), and ODI (852). Citation numbers were positively impacted by article age and participant number but not by tool type or clinical diagnosis. In conclusion, a wide range of PROMs was utilized in the 50 most cited publications in the neurospine surgical literature. The majority were disease-specific rather than generic and targeted particular spine pathology. Neurosurgical PROMs were under-represented amongst the most cited articles. Awareness of the PROMs used in high-impact studies may be helpful in tool selection in future research. PROMs are valuable in standardizing subjective outcomes. Their use in research and clinical settings in any validated language is highly encouraged.

Transcatheter Aortic Valve Replacement in Bicuspid Aortic Valve: A Case Report.

Among other valvular heart disease Aortic stenosis (AS) is the most common in the developed world. Transcatheter Aortic Valve Replacement (TAVR) is most acceptable treatment option for patient with severely calcified aortic stenosis with high and intermediate risk group. Among several challenges, one of the main challenges is to deal with bicuspid aortic valve (BAV). Non-circular annulus, bulky leaflets leading to perivalvular leaks and risk for rupture and often very severe calcification may contribute to periprocedural strokes leading to poor clinical outcome. This case, a 68-year-old woman with a history of type 2 diabetes mellitus (DM), hypothyroidism, bicuspid aortic valve and severe aortic stenosis, bronchial asthma, who had repeatedly refused any suggestion for open heart surgery, was our volunteer candidate for TAVR. After successful TAVR the peak pressure gradient decreased from 100mmHg to 17mmHg. So, TAVR could be a viable option for highly selected patients with severe aortic stenosis and bicuspid aortic valve who have favourable anatomy.

Radiological identification of neuromyelitis optica in a patient presented with unexplained weight loss and generalized weakness: a case report and literature review.

Central nervous system (CNS) inflammatory demyelinating disease known as neuromyelitis optica spectrum disorder (NMOSD) is characterized by recurrent inflammatory events that primarily affect the optic nerves and spinal cord; it may also affect the hypothalamus, area postrema, and periaqueductal gray matter. The NMOSD-specific aquaporin-4 antibody (AQP4-IgG) is available. Myelin oligodendrocyte glycoprotein antibodies (MOG-IgG) have recently been discovered in a group of patients who do not have AQP4-IgG. Case presentation: A 29-year-old female presented to the hospital with the complaint of blurry vision in her right eye and left eye ptosis for 2 days. Two months ago, the patient had a history of generalized fatigue with continuous documented fever with an average of 38.5°C, which was relieved by acetaminophen and ibuprofen. She also complained of continuous hiccups that increased at night and interfered with her sleep pattern and breathing; they lasted for 3 weeks and disappeared suddenly. She had also developed episodes of vomiting and could not tolerate food intake due to which she lost 6 kg within 3 weeks. She was later diagnosed with neuromyelitis optica (NMO) using radiological neuroimaging. Clinical discussion: Early and correct diagnosis, followed by urgent treatment for acute exacerbations and the prevention of further relapses, are essential for treating NMO spectrum illnesses since they entail significant morbidity and, occasionally, fatality. Conclusion: The patient mentioned here represents a typical example of NMO disease. This case emphasizes the presence of this disease in our environment and the importance of accurately diagnosing this ailment, even in a context with minimal resources, to prevent disability.

Enamel matrix derivative for alveolar ridge preservation: A randomized controlled trial.

OBJECTIVE: The aims of this clinical trial were to evaluate the radiographic dimensional changes in alveolar ridge and patient-reported outcomes following tooth extraction and alveolar ridge preservation (ARP) using either deproteinized bovine bone mineral (DBBM) with EMD or DBBM alone. METHODS: Participants requiring at least one posterior tooth extraction and ARP were randomly allocated into two treatment groups: ARP using either DBBM with EMD or DBBM alone. Cone-beam computed tomography (CBCT) images were recorded immediately prior to extraction and at 6 months. Changes in alveolar ridge height (ARH) and alveolar ridge width (ARW) at 1, 3, and 5 mm were recorded. RESULTS: A total of 18 participants with 25 preserved sites were evaluated. ARH and ARW changed significantly from baseline to 6 months for both treatment groups but the difference between the groups was not statistically significant over the 6-month follow-up period (ARH: DBBM/EMD 1.26 ± 1.53 mm vs. DBBM 2.26 ± 1.60 mm; ARW-1 DBBM/EMD 1.98 ± 1.80 mm vs. DBBM 2.34 ± 1.89 mm). A significant difference, favoring DBBM with EMD group, was observed in percentage of sites that had less than 1 mm loss in ARH (54.5% sites in DBBM/EMD group vs. 14.3% sites in DBBM alone group). The participants' perception of bruising, bleeding, and pain in the first two postoperative days was significantly in favor of DBBM alone group. CONCLUSIONS: There were no significant differences in radiographic mean measurements of ARH and ARW following ARB with DBBM and EMD or DBBM alone.

Rare coexistence of primary renal cell carcinoma and primary adrenal adenoma in a cushingoid patient: A case report.

Pituitary or adrenal lesions can cause Cushing syndrome, which has an incidence of 10-15 per million people. A growing variety of tumor subtypes make up the heterogeneous illness known as renal cell carcinoma (RCC). Herein, we described a case with renal clear cell carcinoma and an adrenal adenoma. As was mentioned, it is recommended that these patients routinely have their pituitary-adrenal axis evaluated. The primary etiology of these two illnesses occurring simultaneously is extremely rare.

Influence of implant restorative emergence angle and contour on peri-implant marginal bone loss: A systematic review and meta-analysis.

BACKGROUND: Implant restorative emergence angle and profile may have a negative impact on peri-implant marginal bone level and may increase the risk of developing peri-implantitis. However, the role of these prosthetic features on peri-implant health is still unclear. The aim of this systematic review and meta-analyses was to evaluate the long-term outcomes of implant restorations with an emergence angle of >30° in comparison to those with ≤30° in terms of changes in peri-implant marginal bone level, periodontal parameters, and prevalence rate of peri-implantitis. METHODS: Electronic databases were searched to identify observational studies that compared implant restorations with an emergence angle of >30° to those with ≤30°. The risk of bias was assessed using the Cochrane Collaboration's Risk of Bias tool. RESULTS: Four studies with 912 dental implants in 397 participants were included in the present review. Of these, 455 implants had restorations with an emergence angle of >30°, while the remaining implants had restorative emergence angle of ≤30°. The follow-up time varied between 3.8 and 10.9 years. Implant restorations with an emergence angle of ≤30° were associated with less changes in peri-implant marginal bone level compared to those with emergence angle of >30°. The difference, however, was not statistically significant (mean difference 0.80; 95% confidence interval (CI) -0.13 to 1.72; p = 0.09). In platform-matched implants, the difference between the two groups was statistically significant in favor of implant restorations with emergence angle of ≤30°. In terms of emergence profile, implant restorations with convex profile had significantly higher rate of peri-implantitis (57.8%) compared to implant restorations with concave or straight profile (21.3%) (risk ratio 2.32; 95% CI 1.12-4.82; p = 0.02). CONCLUSIONS: Within the limitation of this review, implant restorations with an emergence angles of >30° or ≤30° seem to have no significant influence on peri-implant marginal bone level. Platform-matched implants with an emergence angle of ≤30° may have positive effects on the peri-implant marginal bone level changes, but the evidence support is of low to moderate certainty.

Unusual location of gouty arthritis with shoulder joint involvement in an elderly male patient: a rare case report.

Gout is a metabolic disease characterized by recurrent episodes of acute arthritis. Gout has been reported in many locations but is rarely localized in the shoulder joint. Case presentation: A 73-year-old man who visited an outpatient clinic with the main complaint of a right shoulder ache lasting 2 weeks came to our attention. The patient reports his discomfort as being of an unbearable character, happening largely at night and preventing him from falling asleep. In the previous 6 months, he had two episodes of the same ailment that lasted around 3-5 days each and spontaneously resolved. Due to the pain's continuance without improvement, the patient now seeks medical assistance. Gout with right shoulder involvement was identified as the cause. Prednisolone 40 mg/day for 10 days, allopurinol 300 mg/day, and colchicine 0.5 mg/day were all prescribed for the patient. After 6 months of follow-up, the patient had significantly improved. Discussion and conclusions: The condition of gout affecting the shoulder joint is quite rare. According to past medical history and clinical manifestations, doctors and orthopedic surgeons should take gouty shoulder arthritis into consideration when there is serious erosion.

Prediction of Coronary Artery Disease Severity by Using CHA2DS2-VASC-HSF Score in Patients with ST-Elevation Myocardial Infarction.

CHADS2 and CHA2DS2-VASc scores are widely used in clinical practice and include similar risk factors for the development of coronary artery disease (CAD). It is known that the factors comprising the newly defined CHA2DS2-VASC-HSF score promote atherosclerosis and associated with severity of CAD. Objective of the study was to find out the association of the CHA2DS2-VASC-HSF score with the severity of CAD in patients with ST elevation myocardial infarction (STEMI). One hundred (100) patients with STEMI were enrolled in this study after considering inclusion and exclusion criteria over a one year period from October, 2017 to September, 2018 in the Department of Cardiology, National Institute of Cardiovascular Diseases, Dhaka, Bangladesh. Coronary angiogram was done within index hospitalization and coronary artery disease severity was assessed by SYNTAX score system. Patients were divided into two groups on the basis of SYNTAX score. Patients with SYNTAX score ≥23 assigned as Group I and SYNTAX score <23 assigned as Group II. The CHA2DS2-VASC-HSF score was calculated. Cut-off value of high CHA2DS2-VASC-HSF score was ≥4.0. In this study mean age of study population was 51.8±9.8, male patients were predominant (79.0%). Among the studied patients, highest percentage had history of smoking followed by hypertension, diabetes mellitus and family history of CAD in Group I patients. It was found that DM and family history of CAD and history of stroke/TIA were significantly higher in Group I than Group II. An increasing trend of SYNTAX score was observed according to the CHA2DS2-VASc-HSF score. SYNTAX score was significantly higher in CHA2DS2-VASc-HSF score ≥4 than CHA2DS2-VASc-HSF score <4 (26.3±6.3 vs. 12.1±7.7, p<0.001). Patients with CHA2DS2-VASC-HSF score ≥4 had severe coronary artery disease than CHA2DS2-VASC-HSF score <4 assessed by SYNTAX score with 84.4% sensitivity and 81.9% specificity (AUC:0.83, 95% CI: 0.746-0.915, p<0.001). CHA2DS2-VASc-HSF score was positively correlated with the severity of CAD. This score could be considered as a predictor of coronary artery disease severity.

Role of Intra-arterial Nitroglycerin (Post Procedural, Prehemostasis) to Reduce Radial Artery Occlusion after Transradial Catheterisation: A Doppler-guided Study.

The study was intended to evaluate efficacy of Intra-arterial nitroglycerin through the sheath at the end of a transradial procedure to preserve the patency of the radial artery. This prospective observational study was done in the Department of Cardiology, National Institute of Cardiovascular Diseases (NICVD), Dhaka, Bangladesh from May 2017 to April 2018, by including a total 200 patients undergoing coronary procedures (CAG and / or PCI) through TRA. RAO was defined as an absence of antegrade flow or monophasic flow or invert flow on Doppler study. In this study 102 patients (Group I) received 200 mcg intra-arterial nitroglycerine, prior to trans-radial sheath removal. Another 98 patients (Group II) did not receive intra-arterial nitroglycerine prior to trans-radial sheath removal. Conventional haemostatic compression methods were applied (average 2 hours) in both groups of patients. Evaluation of radial arterial arterial blood flow by colour Doppler study was done on next day after the procedure in both groups. Results of this study in which RAO was determined by vascular doppler study showed that frequency of radial artery occlusion were 13.5% one day after transradial coronary procedures. We found the incidence was 8.8% vs. 18.4%, (p=0.04) in Group I and Group II respectively. The incidence of RAO was significantly lower in post procedural nitroglycerine group. From multivariate logistic regression analysis diabetes mellitus (p = 0.02), hemostatic compression time for more than 02 hours after sheath removal (p = <0.001) and procedure time (p = 0.02) was predictors of RAO. So, the administration of nitroglycerin at the end of a transradial catheterization reduced the incidence of RAO, as shown by 1 day after the radial procedure by doppler ultrasound.

Heart in Heart: A Case Report of Giant Left Atrial Appendage Aneurysm.

Left atrial appendage aneurysm (LAAA) is a rare cardiac anomaly. The cause mostly due to congenital, but can be acquired also. Patient may remain asymptomatic or may present with variable symptom. It can predispose to hazardous adverse events, including atrial fibrillation, myocardial infarction, cardiac dysfunction and life-threatening systemic thromboembolism. Simple imaging, electrocardiography and echocardiography can diagnose this rare cardiac anomaly. We are reporting a case who presented to us at 5 years of age with palpitation, chest pain and dizziness with arrythmia that developed one month back; he visited our outpatient department of the National Heart Foundation Hospital & Research Institute Hospital, Dhaka, Bangladesh on 13th February 2020. We diagnosed left atrial appendage aneurysm with mitral valve prolapse with atrial arrhythmia thereafter surgical resection of aneurysmal part along with mitral valve annuloplasty done by mid sternotomy and maze therapy. Postoperative period was uneventful and discharged after 6th post operative day.
