Impact of Intranasal Splint Removal Time on Postoperative Complications after Septoplasty

BACKGROUND

Various types of nasal tampons are used for packing after septoplasty. Intranasal splints are widely used as they are more advantageous than other materials regarding the lower complication rates of synechia, and lesser pain during removal. However, there is no consensus on the timing of intranasal splint removal after septoplasty operations.

AIM

In this study, we aimed to investigate the effects of removal time of intranasal splints on postoperative complications after septoplasty.

METHODS

One hundred patients who had septoplasty were randomly divided into two groups according to splint removal time. In group I, the splints were removed on the third postoperative day and in group II, splints were removed on the seventh postoperative day. Pain during splint removal was evaluated by visual analog scale (VAS). Complications of hemorrhage, septal hematoma, crusting, mucosal injury, and infection were recorded during splint removal and compared. In the first postoperative month, hemorrhage, crusting, mucosal injury, infection, synechia, and in the second postoperative month, synechia and perforation rates were compared between two groups.

RESULTS

Mucosal crusting was significantly higher in group II during splint removal. There was no statistically significant difference between the two groups regarding the complication rates and pain scores. Our findings showed no significant difference in pain scores during splint removal and postoperative complications between the two groups except for mucosal crusting.

CONCLUSION

Based on our findings, although there is no consensus on the optimal time for splint removal, earlier removal of splints can be considered a favorable option after septoplasty operations.

Investigation of the prevalence of impacted third molars and the effects of eruption level and angulation on caries development by panoramic radiographs

Background

This study is aimed to determine the prevalence of impacted third molars and to investigate the effects of their eruption level and angulation on caries formation in the distal of the adjacent tooth.

Material and Methods

This cross-sectional study was conducted on panoramic radiographs of 38481 patients who were admitted to the Trakya University, Faculty of Dentistry. The panoramic radiographs of 7998 patients with at least one impacted third molar were included. Third molars were classified according to Winter’s classification and Pell and Gregory’s classification. The frequency of caries in partially impacted third molars and adjacent second molars was determined. The chi-square tests were used to determine potential associations between the third molars' level of eruption, angulation, and caries development.

Results

The study group consisted of 4423 females (55.3%) and 3575 males (44.7%) with a mean age of 36.3±13.4 years. The prevalence of the third molar impaction rate was 23%. The impaction pattern of partially erupted third molars was characterized by an eruption level of A with the vertical position in both jaws. Partially erupted and vertically placed maxillary third molars in the level of position A caused more caries in the adjacent tooth and mesioangularly located partially erupted mandibular third molars were associated with more caries in the adjacent tooth.

Conclusions

The angulation and eruption level of partially erupted third molars should be carefully examined. The prophylactic extraction of vertically and mesioangularly located third molars, especially with an eruption level of position A can be suggested to eliminate the related complications and risk of caries.

Modified Electroconvulsive Therapy in Pseudocholinesterase Deficiency: A Case Report

Introduction.

Pseudocholinesterase (PCHE) deficiency is an inherited condition, in which recovery from anesthetic agents like succinylcholine and mivacurium is slow and complicated with prolonged paralysis of respiratory muscles in susceptible patients. Succinylcholine is used very frequently as a muscle relaxant during the procedure.

Objectives.

In Bakirkoy research and training hospital for psychiatric and neurological diseases, 24.310 patients were hospitalized for acute conditions and 3490 of these patients were treated with electroconvulsive therapy (ECT) in 3 years. We present a very rare case that we encountered in our practice; a severe PCHE deficiency case that could have complicated the modified ECT procedure unless necessary precautions were taken.

Aims.

Detection of PCHE levels of all patients eligible for ECT is part of our pre-ECT assessments procedure, and the case presented here shows the benefits of this method.

Methods.

The patient is a 29-year-old woman, with a 15 year history of schizophrenia. She was hospitalized for homicidal risk and refusal of treatment. Inadequate clinical response with pharmacological interventions and continuous aggressive excitations directed us to consider ECT.

Results.

After the detection of PCHE deficiency (PCHE level: 126 U/L), we performed the modified ECT with propophol and rocuronium instead of succinylcholine as usual. Sugammadex 100 mg was used for fastening the recovery. Response to treatment, which is recorded with positive and negative syndrome scale, was good and we completed 9 ECT sessions without complication.

Conclusions.

Screening for PCHE levels in the pre-ECT assessments is efficacious in order to decrease the complications of the ECT procedure.

Exact solution of the neutron transport equation in spherical geometry

Solution of the neutron transport equation in one dimensional slab geometry construct a basis for the solution of neutron transport equation in a curvilinear geometry. Therefore, in this work, we attempt to derive an exact analytical benchmark solution for both neutron transport equations in slab and spherical medium by using PN approximation which is widely used in neutron transport theory.

Is there a relationship between the diameter of the inferior vena cava and hemodynamic parameters in critically ill patients?

INTRODUCTION

The early detection of critically ill patients together with the rapid initiation of effective treatment in emergency departments(ED) increase the survival rates.

AIM

This study investigated whether a correlation exists between haemodynamic parameters of critically ill patients and the diameter of the inferior vena cava (IVC).

MATERIALS AND METHODS

A cross-sectional study was performed included patients aged ≥18 years with an unstable haemodynamic and/or respiratory status who were referred to the ED for non-traumatic issues. IVC diameters were measured by ultrasound (US) and then central venous pressures (CVP) were measured. Anteroposterior (AP) and mediolateral (ML) diameters of the IVC, both in the inspirium (IAP, IML) and expirium (EAP, EML), were measured by US.

RESULTS

102 patients were evaluated with a median age of 59. The relationship between the diameters of IVC and CVP was evaluated and significant correlation was found in IAP, EAP according to CVP values (p<0.001). ROC analyses were performed and significant relationship was found between the EAP diameter with haemoglobin (Hmg), haemotocrit (Hct), and central venous oxygen saturation (ScvO2) and also significant correlation was detected between the IAP diameter and white blood cell (WBC).

DISCUSSION

We detected significant correlation between the CVP and the IVC diameter in our study compatible with recent studies besides, significant correlation was found between the diameter of the IVC and CVP values as well as between the EAP diameter and Hmg, Hct, ScvO2 levels.

CONCLUSION

Measurement of IVC diameters, especially EAP may be useful at the monitoring of critically ill patients in ED.

Evaluation of the renal resistive index and pulsatility index in patients with pleural effusion by duplex Doppler ultrasonography

OBJECTIVE

The aim of the study was to evaluate the renal resistive index (RI) and pulsatility index (PI) in patients with pleural effusion (PE).

MATERIALS AND METHODS

We studied the mean renal RI and PI in 50 patients with PE and 30 healthy volunteers by Doppler sonography. We grouped effusion as unilateral and bilateral. Statistical analysis was done by independent t test and correlation coefficient analysis.

RESULTS

The mean RI/PI in healthy volunteers and in PE patients was 0.58/0.93 and 0.72/1.35, respectively. We observed a significantly higher RI and PI in patients when compared with healthy volunteers (all p < 0.001). We found no difference between the renal RI or PI related to unilateral (0.71 or 1.34, respectively) or bilateral effusion (0.74 or 1.55, respectively) (p > 0.05).

CONCLUSION

Pleural effusion might result in increased renal impedance as seen in cirrhosis, which is a rather complicated pathophysiological process, without causing any morphological changes in kidneys.
