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.     

Mesangial proliferative glomerulonephritis in familial Mediterranean fever patient with E148Q mutation: the first case report

Familial Mediterranean fever (FMF) is an autosomal recessive hereditary disease characterized by recurrent attacks of fever, usually accompanied by sterile polyserositis. Although amyloidosis is the most common renal involvement, non-amyloid renal lesions, such as glomerulonephritis, have been described in patients with FMF. In this report, we present the first case of an FMF patient with heterozygous mutation of E148Q, mesangial proliferative glomerulonephritis, and no amyloidosis. While the association of mutation E148Q with renal involvement is still obscure, colchicine treatment is useful in mesangial proliferative glomerulonephritis with FMF.     

Influence of smoking on interleukin-1beta level, oxidant status and antioxidant status in gingival crevicular fluid from chronic periodontitis patients before and after periodontal treatment

Toker H, Akp?nar A, Ayd?n H, Poyraz O. Influence of smoking on interleukin‐1beta level, oxidant status and antioxidant status in gingival crevicular fluid from chronic periodontitis patients before and after periodontal treatment. J Periodont Res 2012; 47: 572–577. © 2012 John Wiley & Sons A/S Background and Objective: The aim of this study was to evaluate the impact of smoking on the relationship between interleukin‐1 (IL‐1β) and oxidation in patients with periodontitis and response to nonsurgical periodontal therapy. Material and Methods: Data were obtained from 30 patients with generalized chronic periodontitis (15 smokers and 15 nonsmokers) and from 10 periodontally healthy controls. IL‐1β level, total oxidant status (TOS) and total antioxidant status (TAS) were recorded in gingival crevicular fluid. Probing depth, clinical attachment level, gingival and plaque indices and bleeding on probing were also measured. The gingival crevicular fluid and clinical parameters were recorded at baseline and 6 wk after periodontal treatment. Results: The study showed statistically significant improvement of clinical parameters in both smokers and nonsmokers after periodontal treatment. Moreover, the baseline IL‐1β levels were significantly higher in smokers compared with nonsmokers (p < 0.05). After periodontal treatment, the IL‐1β levels were significantly reduced in both smokers and nonsmokers (p < 0.05). There were no significant differences in TOS and TAS between periodontitis patients and healthy controls at baseline and 6 wk after periodontal treatment. The level of IL‐1β in gingival crevicular fluid was positively correlated with TOS in both smokers and nonsmokers. Conclusions: Periodontal treatment improved the clinical parameters in both smokers and nonsmokers. The results confirm that periodontal therapy has an effect on IL‐1β levels in gingival crevicular fluid, but not on TOS and TAS.     

Histopathological and Biochemical Effects of Ecballium elaterium on Sepsis-Induced Lung Injury

Purpose: The aim of this study was to investigate the role of Ecballium elaterium (EE) on sepsis-induced lung injury. Materials and Methods: A total of 30 male rats were divided into three groups as follows: control, sepsis, and treatment groups (sepsis + EE) with each group containing 10 rats. A rat model of sepsis induced by cecal ligation and puncture (CLP) was used. In the treatment group, rats were injected intraperitoneally with 2.5 mg/kg EE after CLP. Interleukin-6 (IL-6), tumor necrosis factor (TNF)-α, total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) values after a 24-hr period were measured via cardiac puncture. Animals were harvested after the procedure and biochemical analysis was done and histopathological changes of the tissue sections of lungs were examined thereafter. Results: A statistically significant decrease was observed in the IL-6 (p < .05), TNF-α (p < .05), and TOS (p < .01) levels in the sera of the treatment group compared to those of the sepsis group. Following the treatment, the TOS (p = .01) and OSI (p < .05) levels in the lung tissue of rats indicated a statistically significant decrease compared to those of the sepsis group. The histopathological follow-up undertaken after the administration of the EE treatment to septic rats showed significantly lower values of alveolar wall thickness (p < .001), interstitial edema (p = .018), and neutrophil infiltration (p = .047). Conclusion: EE treatment may have beneficial effects on sepsis-induced lung injury, and therefore has potential for clinical use.     

A decision analysis to identify the ideal treatment for adult spinal deformity: is surgery better than non-surgical treatment in improving health-related quality of life and decreasing the disease burden?

Background

Adult spinal deformity (ASD) is a major public health problem. There are pros and cons of the available treatment alternatives (surgical or non-surgical) and it had been difficult to identify the best treatment modality.

Aim

To construct a statistical DA model to identify the optimum overall treatment in ASD.

Methods

From an international multicentre database of ASD patients (968 pts), 535 who had completed 1 year follow-up (371 non-surgical—NS, 164 surgical—S), constitute the population of this study. DA was structured in two main steps of: (1) baseline analysis (assessing the probabilities of outcomes, assessing the values of preference—utilities-, combining information on probability and utility and assigning the quality adjusted life expectancy (QALE) for each treatment) and (2) sensitivity analysis.

Results

Four hundred and thirty-two patients (309 NS, 123 S) had baseline and 1 year follow-up ODI measurements. Overall, 104 (24.1 %) were found to be improved (a decrease in ODI > 8 points), 225 (52.1 %) unchanged (?8 > ODI > 8) and 65 deteriorated. Surgery presented with a higher chance of improvement (54.2 %) versus NS (9.7 %). The overall QALE ranged from 56 to 69 (of 100 years) and demonstrated better final QALE in the NS group (60 vs. 65, P = 0.0038), this group having started with higher QALE as well (56 vs. 65 years, P < 0.0001). There were improvements in overall QALE in both groups but this was significant only in the surgical group (S from 56 to 60 years, P < 0.0001; NS from 65 to 65 years, P = 0.27). In addition, in the subgroup of patients with significant baseline disability (ODI > 25) surgery appeared to yield marginally better final QALE (58 vs. 56 years, P = 0.1) despite very a similar baseline (54 vs. 54 years, P = 0.93).

Discussion and conclusions

This study demonstrated that a single best treatment modality for ASD may not exist. Conservative treatment appears to yield higher (up to 6 %) QALE compared to surgery, most probably secondary to a higher baseline QALE. On the other hand, surgery provides a significantly higher increase in QALE. Especially in patients with significant disability at baseline, the final QALE tended higher in the S group (although not significant). Finally, chances of a relevant improvement at first year turned out to be significantly lower with NS treatment.
