Background: Recent articles have hypothesized a possible correlation between dental implants dissolution products and peri-implantitis. The null hypothesis tested in this case-control study was that there would be no differences in salivary concentrations of titanium (Ti), vanadium (V), nickel (Ni) and arsenic (As) ions among patients with dental implants, healthy (Group A) or affected by peri-implantitis (Group B), compared to subjects without implants and/or metallic prosthetic restorations (Group C). Methods: Inductively coupled plasma mass spectrometry was used to analyze saliva samples. One-way repeated-measure analysis of variance (ANOVA) was used to identify statistically significant differences in the salivary level of Ti, V, Ni and As between the three groups. Results: A total of 100 patients were enrolled in the study (42 males and 58 females), distributed in three groups: 50 patients in Group C, 26 patients in Group B and 24 patients Group B. In our study, concentrations of metallic ions were higher in Group A and B, compared to the control group, with the exception of vanadium. However, there were no statistically significant differences (p > 0.05) for metallic ions concentrations between Group A and Group B. Conclusions: Based on our results, there are no differences in titanium or other metals concentrations in saliva of patients with healthy or diseased implants.

Abstract Purpose The primary objective of this study was to evaluate the testicular stiffness by ultrasound shear wave elastography (SWE) both in men with oligo-astheno-teratozospermia (OAT) and in control group. The secondary objective was to identify a possible correlation between semen quality with testicular stiffness. Methods This was a prospective case-control study. We divided the sample in two groups; Group A (case group) included men with OAT, and Group B (control group) men with normal sperm parameters. All participants had at last two semen analysis in the past 180 days (at last 90 days apart), using performed ultrasound and SWE elastography. Results We analyzed 100 participants, 50 patients in Group A and 50 controls in Group B. There were statistically significant differences in term of testicular volume and testicular stiffness between two groups. Men with OAT had the testicular stiffness value higher than the controls in both sides (left testicular stiffness 21.4 ± 5.4 kPa vs 9.9 ± 1.6 kPa, p < 0.0001; right testicular stiffness 22.9 ± 4.8 kPa vs 9.5 ± 2.4 kPa, p < 0.0001). Men with abnormal semen parameters showed an inverse correlation between the mean value of testicular stiffness and total sperm count (22.15 ± 3.38 kPa, r = − 0.387, p = 0.005), sperm concentration (22.15 ± 3.38 kPa, r = − 0.244, p = 0.04), and progressive motility (22.15 ± 3.38 kPa, r = − 0.336, p = 0.01), while the correlation was not evident in controls group. Conclusion SWE is able to differentiate between testicles with spermatogenic changes from a healthy testicle. For this reason, it could be used to evaluate, in a non-invasive way, the tissue alterations of the organ.

Introduction: Mild pancreatitis is a self limiting disease, while morbidity and mortality is considerably high in cases of severe necrotizing pancreatitis. Octreotide reduces secretion, release and activation of exocrine hormones; there is collection of pancreatic hormones in duct which in return causes irreversible destruction of the exocrine and endocrine pancreatic parenchyma leading to mal-digestion and diabetes. There are lot of controversies in the treatment of acute pancreatitis, so through this study we tried to evaluate whether there is a beneficial role of octreotide or not. Materials and Method: This case control study was done on patients admitted for the treatment of acute pancreatitis at a tertiary care hospital in Central India. This is retrospective study. The data of inpatient records were taken from the medical records department (MRD) of the hospital. The diagnosis of patients was established on basis of biochemical and radiological investigations. The patients were divided into two groups; cases and control, cases had received octreotide along with fluids (group A) controls received fluids without octreotide (group B). Symptomatic treatment was given in both the groups. Ages of the cases and controls were matched (±3 years). The statistical analysis of data was done and results were obtained. Results: In this retrospective case control study the records of fifty two patients were selected. The mean age in Group A was 35 ±16.45 years and in Group B 40±17.51 years in Group B (tA/B1.061; p ˂0.294). There were 22 males and 4 females in group A, while 20 males and 6 females in group B. Both the groups were comparable. All the patients in octreotide group survived while there were three deaths in control group. As far as mean hospital stay is was 10 days ± 7.10 in group A while it was 7 days ±3.65 in group B. All the p values for the criteria of study are non-significant. But when we talk about percentage, 11.53% patient died in control group. Conclusion: In our study we found that octreotide does not affect the final outcome of patients with acute pancreatitis. There is no effect on hospital stay and reduced need of analgesics in patients with acute pancreatitis. Keywords: Acute Pancreatitis; Octreotide; Hospital Stay; Mortality

Objectives: Cardiovascular diseases cause worse outcomes in patients affected by COVID-19. High coronary artery calcium score (CACS) and aortic valve calcifications (AC) increase cardiovascular risk. Our purpose is to evaluate CACS, measured by Weston Score (WS), and presence of AC in chest CT of COVID-19 patients and possibly to investigate their prognostic role. Material and methods: This retrospective case-control study includes 150 hospitalized COVID-19 patients who underwent a chest CT at admission. The case group (Group A) was formed by 50 in-patients in Intensive Care Unit (ICU) under invasive ventilation (IV), while the matching control group for sex, age and BMI (Group B) was formed by 100 in-patients in non-ICU units, not under IV. After, a second case-control selection was originated from these two Groups: the case group (Group A1) composed by 30 patients selected from Group A, and the matching control group for age, sex, BMI and CT lung severity score (LSS) (Group B1) composed by 60 patients selected from Group B. WS and the presence of AC were compared between Groups A and B, and between Groups A1 and B1. Moreover, LSS and WS were correlated. Parametric tests were used for statistical analysis.

Results: Among the 150 patients, 105 (70.0%) were male and 45 (30.0%) female. The age was 70.2 ± 13.3 years. LSS was 7.5 ± 3.9, WS was 6.4 ± 3.0; AC was present in 97/150 (64.7%). WS was significantly higher in Group A than in Group B, respectively, 7.4 ± 4.0 and 5.7 ± 2.6 (p=0.0146), and also the presence of AC, respectively, 41/50 (82.0%) vs 56/100 (56.0%) (p=0.0016). In Group B, LSS and WS had a linear positive correlation (r=0.2240, p=0.0405). Finally, WS and AC were significantly higher in Group A1 compared to Group B1. Conclusions: Both WS and AC were higher in ICU COVID-19 patients than in non-ICU COVID-19 patients: they could have a predictive role in the pejorative evolution of the disease.

A prospective case control study was conducted at Medical College, Kolkata with the aim of evaluating the role of isoflavone( a class of phytoestrogen –plant compounds having the beneficial effects of estrogen but lesser risks and side effects) in postmenopausal women. 100 postmenopausal women (those who underwent total abdominal hysterectomy and bilateral salpingooopherectomy for different benign indications, aged between 40-50 years and who were menstruating before operation) were alternately distributed into two groups-Group A (n=50, received 60mg of isoflavone and 500mg of calcium per day for 6 months) and Group B (n=50, received 500mg of calcium per day only for 6 months). To evaluate the menopausal symptoms, the menopausal Kupperman index questionnaire was applied. Other outcomes measured were body mass index, blood pressure and lipid profile. Menopausal symptoms in Group A(those using isoflavones) were lower compared to Group B. The present study showed that Kupperman index decreased significantly in Group A (from 28.48 ± 2.03 to 16.32 ± 1.06 i.e. 45% decline) compared to Group B (from 24.56 ± 1.52 to 18.44 ± 1.11 i.e. 25% decline). No differences in blood pressure or body mass index were found during treatment between the two groups. . In our study total cholesterol, triglycerides and low-density lipoproteins (LDL) decreased significantly in Group A compared to Group B. Therefore our clinical study indicates that isoflavone can be an invaluable resource for postmenopausal women for combating menopausal symptoms.

Abstract Introduction Capillary malformations (CMs) can be sporadic or syndromic, in association with other underlying venous malformation (VM) or lymphatic malformation (LM). The objective of this study is to describe the clinical patterns in the neonate that allow us to differentiate sporadic CMs from those associated with other vascular malformations. Materials and Methods A case–control study was performed in neonates with CM located in the trunk, followed at our institution between 2008 and 2018. The patients were divided into two groups: group A (cases: CM associated with VM or LM) and group B (controls: sporadic CM without associated malformations). Demographic and clinical variables collected in the clinical history were evaluated (color, location, multifocality, bilaterality, position regarding the vascular axis, and involvement of the midline). Results Thirty-eight patients were included (18 cases and 20 controls) without differences in gender and age. In group A, the totality of patients presented CM with uniform color and lateral location (p < 0.001). In this group, bilateral and multifocal involvements were lower than in group B, without significant differences between both groups. The distribution of CMs in group A was always parallel to the vascular axis and the midline was always respected, without observing these characteristics in the group B (p < 0.001). Conclusion The presence of a CM in the trunk of a neonate with uniform color, lateral location, parallel position to the vascular axis, and absence of involvement of the midline should make us suspect other underlying vascular malformations, which should be studied with complementary tests.

ABSTRACT Introduction Rheumatoid arthritis (RA) and periodontitis are common chronic inflammatory conditions. Several studies suggested a relationship between RA and periodontitis. Recent studies have shown a beneficial effect of periodontal treatment on the severity of active RA. So the aim of this study was to examine the effect of nonsurgical periodontal therapy on the clinical parameters of RA. Materials and methods A total of 60 subjects with moderateto- severe chronic generalized periodontitis and active RA in the age range 18 to 65 were selected for the study. They were divided into two groups. Group A (control group) consisted of 30 subjects with chronic generalized periodontitis and RA, and group B of 30 subjects with chronic generalized periodontitis and RA and they received nonsurgical periodontal therapy (scaling, root planning, and oral hygiene instructions). Evaluation of clinical observations of Simplified Oral Hygiene Index (OHI-S), gingival index (GI), bleeding on probing (BOP), probing pocket depth (PPD), clinical attachment level (CAL), number of swollen joints (SJ), number of tender joints (TJ), values of erythrocyte sedimentation rate (ESR), visual analogue scale (VAS) for patient's global assessment, 3 months disease activity score (DAS) index, and C-reactive protein (CRP) was done at baseline and 3 months. Statistical evaluation of clinical observations was carried out. Results Group B subjects who received nonsurgical periodontal therapy showed statistically significant improvement in all periodontal and RA parameters at 3 months, compared with group A who did not receive periodontal therapy. Conclusion It can be concluded from the result that nonsurgical periodontal therapy may contribute to reduction in severity and symptoms of RA. Clinical significance Rheumatoid arthritis patients should be evaluated for periodontitis and treated for the same in order to reduce its severity level.

<b><i>Background:</i></b> Congestive heart failure (CHF) associated with worsening renal function is a very common disorder, and, as well known, the goal of the treatment is reducing venous congestion and maintaining a targeted extracellular volume. The objective of the study is to evaluate regular peritoneal ultrafiltration treatment compared to a standard conservative approach in NYHA III–IV CHF patients. In particular, the primary endpoints of the study were the major event-free survival and the total days of medical care per month (which consist of the days of hospitalization and the number of outpatient visits). <b><i>Material and Methods:</i></b> This is a retrospective case-control study. Twenty-four patients were included in the present study. Twelve consecutive patients were treated with peritoneal treatment (group A) and 12 matched for age, gender, and severity of disease with a standard approach. Patients were observed over a maximum period of 18 months. Information on events, hospitalizations, and number of visits was collected during follow-up. <b><i>Results:</i></b> During the follow-up, we observed a major event in 4 patients in group A (33.3%) and in 8 patients in group B (66.7%). In group B, we observed 7 deaths and 1 ICD shock, while in group A, 3 deaths and 1 ICD shock. The number of visits per month was significantly lower in patients treated with the peritoneal method (1.2 [0.4–4.1] vs. 2.5 [2.0–3.1]; <i>p</i> = 0.03). The total days of medical care was significantly lower in group A (2.0 [1.1–5.5] vs. 4.4 [3.0–8.7]; <i>p</i> = 0.034). A multiple event analysis according to the Andersen-Gill model showed a significant event-free survival for group A. During the follow-up, we did not observe any episode of peritonitis in the treated group. <b><i>Conclusions:</i></b> Our study shows that the peritoneal technique is a good therapeutic tool in well-selected patients with CHF. In accordance with prior experience, this intervention has not only an important and significant clinical impact but also potential economic and social consequences.

Object. The role of stereotactic radiosurgery (SRS) for recurrent glioblastoma multiforme (GBM) was evaluated in a case—control study. Methods. All patients who underwent SRS for recurrent GBM before March 2003 formed the case group. A control group of patients who did not undergo SRS was created from an institutional database, and each case was matched for known prognostic factors in GBM. The medical and neuroimaging records of all the patients were reviewed, and survival and treatment outcomes were recorded. The case and control groups were well matched with regard to demographics and pre-SRS interventions. In the control group, the date on which magnetic resonance imaging identified a recurrent lesion that would have been eligible for SRS was deemed the “SRS” date. The number of surgeries performed in the control group was statistically higher than that in the case group. The median duration of overall survival from diagnosis was 26 months in the case group and 23 months in the control group. From the date of SRS or “SRS”, the median duration of survival was 11 months in the case group and 10 months in the control group, a difference that was not statistically significant. Conclusions. It appears that a subgroup of patients with GBMs has a higher than expected median survival duration despite the initial prognostic factors. In patients with localized recurrences, survival may be prolonged by applying aggressive local disease management by using either SRS or resection to equal advantage.

Abstract Background: Wide-awake local anesthesia no tourniquet (WALANT) is a promising technique for bony procedure in recent years. During distal radius surgery via WALANT technique, surgeons may concern about intraoperative pain. This prospective case-control study was aimed to compare the intraoperative hemodynamic changes between WALANT technique and general anesthesia (GA) in patients undergoing distal radius plating surgery.Methods: We recruited 40 adults with distal radius fracture underwent plating using the WALANT technique (group A) or general anesthesia (group B). Each group comprised 20 patients with similar demographics. Mean arterial pressure (MAP) and heart rate were recorded in both groups. Intraoperative pain intensity was measured by numeric rating scale (NRS) for pain in group A.Results: The NRS decreased significantly compared with preoperative status in group A for most of the intraoperative period. The intraoperative MAP in group A showed no significant change among each peri-operatively period. In addition, group A showed less peri-operative MAP fluctuation than group B (p< 0.05). The intraoperative changes in HR showed significant changes between group A and B during reduction, plating and skin closure. The reduction and plating quality were similar between each group.Conclusions: Patients undergoing distal radius plating surgery via WALANT technique has a lower MAP changes. Distal radius plating surgery using the WALANT technique is a well-tolerated surgical procedure and showing the similar reduction and plating quality to through GA.
