Management of open apices in thirteen traumatized permanent incisors using mineral trioxide aggregate: Case series

AimThe partial pulpotomy can offer a successful outcome for the treatment of traumatic complicated crown fractures. The aim of this clinical report was to evaluate the effect of mineral trioxide aggregate (MTA) in apexogenesis of traumatized immature permanent incisors with pulp exposure.Case reportAccording to clinical and radiological examinations complicated crown fractures and open apices were identified in 13 permanent upper incisors in ten patients (age range 7–10 years). Partial pulpotomy procedures were performed and the teeth were treated with MTA. In this report, periodic clinical and radiological follow-ups were performed. At recall examinations, all teeth were asymptomatic, and clinical and radiological investigations revealed excellent healing patterns with continued apexogenesis.ConclusionRegular examination of immature traumatized permanent teeth is critical for vitality and apexification. In this report, clinical and radiological findings confirm that partial pulpotomy with MTA is a reliable and effective treatment approach in apexogenesis of traumatized immature permanent incisors with pulp exposure.     

Determination of the appropriate catheter length and place for needle thoracostomy by using computed tomography scans of pneumothorax patients

Introduction

The primary goal of this study was to compare the chest wall thicknesses (CWT) at the 2nd intercostal space (ICS) at the mid-clavicular line (MCL) and 5th ICS at the mid-axillary line (MAL) in a population of patients with a CT confirmed pneumothorax (PTX). This result will help physicians to determine the optimum needle thoracostomy (NT) puncture site in patients with a PTX.

Materials and methods

All trauma patients who presented consecutively to A&E over a 12-month period were included. Among all the trauma patients with a chest CT (4204 patients), 160 were included in the final analysis. CWTs were measured at both sides and were compared in all subgroup of patients.

Results

The average CWT for men on the 2nd ICS-MCL was 38 mm and for women was 52 mm; on the other hand, on the 5th ICS-MAL was 33 mm for men and 38 mm for women. On the 2nd ICS-MCL 17% of men and 48% of women; on the 5th ICS-MAL 13% of men and 33% of women would be inaccessible with a routine 5-cm catheter. Patients with trauma, subcutaneous emphysema and multiple rib fractures would have thicker CWT on the 2nd ICS-MCL. Patients with trauma, lung contusion, sternum fracture, subcutaneous emphysema and multiple rib fractures would have thicker CWT on the 5th ICS-MAL.

Conclusions

This study confirms that a 5.0-cm catheter would be unlikely to access the pleural space in at least 1/3 of female and 1/10 of male Turkish trauma patients, regardless of the puncture site. If NT is needed, the 5th ICS-MAL is a better option for a puncture site with thinner CWT.     

The Relationship between the MEFV Genotype,Clinical Features,and Cytokine-Inflammatory Activities in Patients with Familial Mediterranean Fever

Familial Mediterranean Fever (FMF) is an autosomal recessive disease characterized by periodic attacks of fever and polyserositis. The effects of the MEFV genotype differences on clinical picture and inflammatory activity have not been well documented. The aim of this study was to investigate levels of conventional inflammation markers, procalcitonin, interleukin levels, TNF-alpha, and C5a levels in patients with FMF who had different MEFV genotypes and compare them with those of healthy subjects. The study consisted of 41 patients with FMF (F/M: 23/18), and 31 healthy subjects (F/M: 18/13). Tests were performed during the attack-free period.

White-blood cell count, CRP and IL-8 levels were higher in patients with FMF than in healthy subjects (p < 0.05) and also higher in M680I carriers than in the patients with M694V allele carriers. However, ESR, fibrinogen, procalcitonin, IL-6, C5a, TNF-alpha, and IgD levels were not significantly different between patients and healthy subjects (p > 0.05). Arthralgia or arthritis was significantly higher in M694V carriers than in non-M694V carriers (p < 0.05). It is concluded that the clinical features and inflammatory-cytokine activities were higher in patients with FMF during the attack-free period than in healthy subjects, and the different genotype might be related to different clinical pictures.     

Waist circumference is associated with carotid intima media thickness in peritoneal dialysis patients

Purpose

Atherosclerosis is responsible for the high mortality rate in end-stage renal disease patients. Defining risk factors for atherosclerosis may lead to reduction in cardiovascular disease through modification of these factors. Peritoneal dialysis (PD) patients are subjected to high glucose loads on a daily basis, which results in considerable weight gain and an increase in waist circumference (WC). WC as an indicator of abdominal obesity is a risk factor for atherosclerosis in the general population. Carotid artery intima media thickness (CIMT) measurement is a reliable method for the detection of early atherosclerosis. The aim of this study was to investigate the relationship between WC and CIMT and to define risk factors associated with CIMT in PD patients.

Methods

Fifty-five PD patients and 40 healthy controls were included. Atherosclerosis was assessed using measurement of CIMT. Fasting blood was collected for analysis. Anthropometric parameters (age, weight, BMI, and WC) were measured.

Results

Peritoneal dialysis patients had higher WC (93.9 ± 1.7 vs. 87.3 ± 1.2 cm, p < 0.05) and CIMT (0.70 ± 0.02 vs. 0.57 ± 0.01 mm, p < 0.01) than the control group. On univariate analysis, age, WC, plaque formation, and D/P creatinine were positively correlated with CIMT, whereas residual renal function, albumin, ultrafiltration volume, and D/D0 glucose were negatively correlated. On multivariate analysis, only age, WC, and plaque formation showed correlation (p < 0.001).

Conclusions

Carotid artery intima media thickness is associated with age, plaque formation, and WC in PD patients. WC measurement is a simple, inexpensive, reproducible, and reliable method of evaluating atherosclerosis risk in PD patients and should be assessed at every visit. Appropriate counsel should be provided to patients with greater WC who are deemed to be at risk for atherosclerosis.     

Adenocarcinoma of the Esophagus in the Young

Introduction

Practitioners have noted a striking increase in the number of young patients under the age of 40 years old who develop esophageal adenocarcinoma. The aim of this study was to characterize the presentation, pathology and therapeutic outcome of these young patients.

Methods

The records of patients who presented to the Foregut Surgical Service at the University of Southern California with esophageal adenocarcinoma between 2000 and 2007 were retrospectively reviewed. The presentation, tumor stage and histology, therapy and outcome of the patients under the age of 40 were compared to those ≥40.

Results

Of the 374 patients reviewed, 20 (5 %) were under the age of 40. There were two patients in their second and 18 in their third decade of life. The youngest patient was 25 years old. A history of gastroesophageal reflux disease or Barrett’s esophagus was less common in patients <40 than in those ≥40; 15 and 5 % compared to 61 and 46 %. Similarly, patients <40 had a significantly longer time interval between the onset of symptoms and the diagnosis of their cancer than those ≥40; 4.5 vs. 2 months, p?=?0.04. They also had a higher prevalence of stage IV disease (30 vs. 6 %, p?=?0.0003), a shorter time to recurrence (9.5 vs.19 month, p?=?0.002), and a poorer median survival (17 vs. 43 month, p?=?0.04).

Conclusion

Esophageal adenocarcinoma in patients <40 years old commonly presents with an advanced stage of the disease and an associated poor survival. This is likely due to a low index of suspicion that dysphagia seen in younger patients is due to a malignancy.     

The effects of chronic periodontitis and rheumatoid arthritis on serum and gingival crevicular fluid total antioxidant/oxidant status and oxidative stress index

Background: Chronic periodontitis (CP) and rheumatoid arthritis (RA) appear to share many pathologic features. Oxygen metabolism has an important role in the pathogenesis of both CP and RA. The aim of this study is to evaluate the relationship between these two chronic inflammatory diseases with regard to antioxidant and oxidant status. Methods: A total of 80 participants were divided into four groups of 20 each: group RA–CP (patients with RA and CP), group RA (periodontally healthy patients with RA), group CP (systemically healthy patients with CP), and group C (periodontally and systemically healthy volunteers) were included in the study. After assessment of periodontal measurements, gingival crevicular fluid (GCF) samples were taken at one incisor, premolar, and molar tooth and stored with serum samples at ?80°C for the antioxidant/oxidant assay. Results: Although all clinical measurements in groups RA–CP and CP were statistically higher compared to those of C and RA groups (P <0.001), there were no differences between CP and RA–CP groups (P >0.05). GCF total oxidant status (TOS) values of CP and RA–CP groups were higher than those of the RA group (P <0.05). GCF oxidative stress index (OSI) values of the RA–CP group were higher than those of the RA group (P <0.05). There were no differences among the groups in terms of serum TOS and OSI values (P >0.05). Conclusions: Local OSI values in groups with patients with CP were higher, whereas systemic OSI values showed no difference among the groups. The presence of RA seems not to affect local and systemic OSI values in patients with CP.
