Atypical presentation of primary giant nasal septal mucopyocele

Mucoceles are expansile, encapsulated, benign cystic lesions with the potential for adjacent bony remodeling and resorption. Previous nasal surgery, recurrent infections, allergies, and facial traumas are all possible causes of mucoceles involving mainly paranasal sinuses. When the mucocele is infected, it is referred to as mucopyocele. Nasal septal mucoceles seen in only very seldom cases might develop from pneumatized and infected nasal septa. In the current article, we present an interesting primary giant septal mucopyocele that destroys all paranasal cells as a tumoral lesion. The perpendicular plate of ethmoidal bone, vomer, and bilateral anterior and posterior ethmoidal cells were destroyed by mucopyocele. The nasal cavity was totally obstructed by lesions on both sides. On the left side, the lesion also eroded the left lateral nasal wall causing external swelling at the medial canthal region. This is the first case of a giant septal mucopyocele of its kind in the literature. Although nasal septal mucocele is very rare, it should be considered in differential diagnosis of intranasal masses.     

Giant arteriovenous malformation of the floor of the mouth presenting with dysarthria and difficulty in swallowing

Arteriovenous malformation (AVM) is a vascular abnormality resulting in the development of abnormal connection between an artery and vein without capillary connections. An AVM develops mainly intracranially. Extracranial AVMs are rarely seen. Cheek, ear, nose, auricle, and forehead are the more common sites in the extracranial involvement. They cause cosmetic problems when located in the head and neck region. We report a case of a giant AVM in the floor of the mouth, which has not been specified and has not been reported until now. The lesion, in an elderly man, was supplied by multiple vessels and caused difficulty in speaking and swallowing. The lesion was totally excised after embolization of feeding vessels.     

Nasopharyngeal sarcoidosis: a rare involvement

Sarcoidosis is a chronic, multisystemic, non-caseating granulomatous disease of unknown etiology. Nasopharyngeal involvement is very rare in sarcoidosis. The objective of this report was to evaluate a rare involvement of sarcoidosis. This report includes a case of nasopharyngeal sarcoidosis. A 51-year-old female with nasopharyngeal sarcoidosis was treated as sarcoidosis, and she was better. Nasopharyngeal involvement is very rare in sarcoidosis but it must be kept in mind.     

Quantitative evaluation of right ventricle function by transthoracic echocardiography in childhood congenital heart disease patients with pulmonary hypertension

Introduction and Objective: The present study aims to quantitatively evaluate the right ventricle (RV) function by means of transthoracic echocardiography in normal children and childhood congenital heart disease patients with pulmonary hypertension. Patients and Methods: This study was conducted in a cohort including 40 healthy children and 30 pediatric patients with pulmonary hypertension who were diagnosed under close surveillance at the study center between October 2009 and November 2010. Results: Statistically significant differences were found between the patient and control groups for the right ventricle myocardial performance index (RVMPI), the left ventricle myocardial performance index (LVMPI), the tricuspid valve systolic flow velocity (Ts), the ratio of systolic pulmonary artery pressure to the right ventricle outflow tract systolic flow velocity time integral (sPAP/RVOT VTI), and the ratio of systolic pulmonary artery pressure to right ventricle outflow tract systolic flow velocity time integral × heart rate (sPAP/[RVOT VTI×HR]). When the children were divided into three groups based on their pulmonary vascular resistance significant differences emerged that predicted an increasing severity of RV dysfunction. Significant differences were also observed for the RVMPI, the LVMPI, and the Ts as well as for echocardiographic pulmonary flow (Qp) and systemic flow (Qs). Discussion: The present study demonstrates that echocardiographic parameters can be used for the quantitative detection of RV dysfunction in childhood congenital heart disease patients with high pulmonary artery pressure (systolic, diastolic, and mean) or pulmonary vascular resistance.     

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.     

Low plasma renin activity and high aldosterone/renin ratio are associated with untreated isolated systolic hypertension

Abstract Objective. Isolated systolic hypertension (ISH) is generally encountered in elderly patients and there are scarce data regarding the renin-angiotensin-aldosterone system (RAAS) activity in patients with ISH. We aimed to determine the plasma renin activity (PRA), plasma aldosterone levels (PAL) and aldosterone/PRA ratio (PAL/PRA) in patients (age >50 years) with ISH and to compare these values with patients with essential hypertension (EH) as well as subjects with normal blood pressure values (control) who have similar age and cardiovascular risk profile. Methods. Consecutively, 42 untreated ISH patients, 30 patients with EH and 29 normal subjects were included in the study. Parameters were presented as median (interquartile range). Results. There were no significant differences regarding age, gender and other cardiovascular risk factors among groups. As expected, systolic, diastolic blood pressure and pulse pressure values were significantly different among groups. Besides, PRA values were found to be significantly lower in patients with ISH (0.4 [0.2-1.1] ng/ml/h) compared with the EH (0.95 [0.5-2.6] ng/ml/h, p =0.024) and control (1.3 [0.7-2.1] ng/ml/h, p =0.001) groups. Although, PAL were similar among groups, PAL/PRA ratio was significantly higher in ISH group (134.1 [73-224]) compared with those with EH (42.2 [35-84], p <0.001) and the control group (53.3 [30-106], p =0.001). No significant difference was present with respect to PAL/PRA ratio between EH and control groups. Conclusions. Our findings suggested that in patients with ISH, despite lower PRA levels, PAL/PRA ratio is significantly higher compared with the patients with EH and subjects with normal blood pressure. Since higher PAL/PRA levels is an indicator of relative aldosterone excess, medications blocking RAAS activity including aldosterone antagonists may have useful cardiovascular consequences in addition to their antihypertensive effects in ISH.
