Objective To determine the prevalence and site of varicocele and varicocele‐related testicular atrophy in children and adolescents.

HRCT evaluation of the accessory fissures of the lung

INTRODUCTION The purpose of this study was to classify the accessory fissures of the lung and to assess their frequency by using high-resolution CT. METHODS AND PATIENTS HRCT scans of 115 patients were prospectively reviewed. 1 mm thin sections were obtained at 10 mm intervals with a scan time of 1.9 s. The fissure and its relationship to the segmental bronchovascular structures were then evaluated on transverse sections. RESULTS Forty-four accessory fissures were detected in 35 of 115 patients. The most common accessory fissure was the inferior accessory fissure (12%). The second most common accessory fissure was the left minor fissure (8%). The right superior accessory fissure (5%), the accessory fissure between the medial and lateral segments of the right middle lobe (5%), and the accessory fissure between the superior and inferior segments of the lingula (5%) were seen in equal frequencies. Also, intersegmental accessory fissures, namely the fissure between the anterobasal and laterobasal of both the right (1%) and the left (2%) lower lobes were detected. We found only one subsegmental accessory fissure. DISCUSSION AND CONCLUSION The inferior accessory fissure and the left minor fissure were the most common accessory fissures in our study.

Grisel's syndrome

Summary Atlantoaxial subluxation is a rare complication of the upper neck inflammatory processes of head and neck region. Grisels syndrome is a non-traumatic subluxation of the atlanto axial joint. It is not associated with trauma or bone disease. It typically occurs in children after serious infection in the head and neck region. Several theories have been proposed to explain the pathogenesis of inflammatory subluxation. The primary treatment of Grisels syndrome is medical. We report a case of atlantoaxial rotatory subluxation treated with external fixation and antibiotic therapy.

The assessment of constipation in monosymptomatic primary nocturnal enuresis

Objective: Nocturnal enuresis and constipation are common pediatric problems. The aim of this study was to assess the incidence of constipation in children with or without monosymptomatic primary nocturnal enuresis.Methods: The study included 5350 children, ages 5–19 years, who were surveyed to detect the incidence of nocturnal enuresis. Of those surveyed, 679 (12.7%) had primary nocturnal enuresis. All children were questioned by mail with a standard form that addressed their micturition and defecation habits. The children those who had primary nocturnal enuresis were invited to the Pediatric Urology Section of the University Hospital. Of those 679 children, 125 kept that invitation. All 125 of those children underwent an abdominal ultrasound. Also, these children had serum creatinine levels drawn and plain abdominal films taken.Results: Constipation, defined as less than 3 bowel movements per week, was seen in 48 of 679 children with nocturnal enuresis (7.06%). Of those 4671 children without nocturnal enuresis, only 68 (1.45%) had constipation. The difference in constipation between the two groups was statistically significant (z = −9.251; p = 0.000). Of note, 10 of the 125 children (8%), evaluated at the hospital, had constipation. None of the children had an abnormal neurologic examination. Finally, faecal loading was detected on the plain films of 8 of the 125 children evaluated, 7 of who had constipation. The sensitivity of grading plain films for faecal loading to denote constipation in this population was 87.5%.Conclusions: Children with primary nocturnal enuresis should be thoroughly assessed for coexisting constipation.

Antrolithiasis: a retrospective study.

In this retrospective study, the computed tomography (CT) archives of paranasal sinus examinations were reviewed and three cases of antroliths are presented. The archives of paranasal sinus CT studies of 1957 patients (1023 females, 934 males, mean age 36.5 years) were surveyed. CT studies were performed using 3 mm collimation and interval in the coronal, axial or both coronal and axial planes. Three out of 1957 patients demonstrated antroliths, all in the left maxillary sinus. Associated sinusitis was detected in all three patients. Only one patient was operated. The chemical analysis of the antrolith revealed it to be a calcium oxalate stone. All the relevant literature is reviewed and only 25 other cases of true antrolithiasis were encountered. The clinical and radiological features of antroliths, as well as differential diagnosis were discussed. Antrolithiasis should be considered in any case of sinusitis, that does not respond to appropriate medical therapy.

An Unusual Cause of Intestinal Obstruction: Abdominal Cocoon

OBJECTIVE abdominal cocoon is characterized by total or partial encasement of the small bowel by a thick fibrotic membrane, leading to mechanical obstruction. Here, we report two cases of abdominal cocoon; both patients presented with symptoms of intestinal obstruction. CONCLUSION We describe the CT and sonographic features of this disease, emphasizing the role of MDCT, and discuss the preoperative diagnostic clues.

Choanal polyp originating from the middle turbinate.

Choanal polyps usually originate from the maxillary sinus. Unusual origins such as the sphenoid sinus, ethmoid sinus, nasal septum and hard and soft palate have been reported in the literature. Herein, we report a rare case of choanal polyp originating from the middle turbinate that was removed by an endoscopic surgery technique. The computed tomographic findings are described and the literature is reviewed.

Disseminated pneumocephalus secondary to an unusual facial trauma

Pneumocephalus can be secondary to a postintrathecal procedure, sinus fracture, basilar skull fracture, congenital skull defect, neoplasm, gas producing organism, barotrauma, neurosurgery, paranasal sinus surgery, mask or nasal continuous positive-airway pressure. Unusual facial traumas can also be rare causes of pneumocephalus. Here, we present such a case in whom an air compressor tip injury to both eyes led to the disseminated pneumocephalus. We report this rare case with the computed tomography findings and try to explain the possible mechanism of the pnemocephalus.

Primary diffuse tracheobrochial amyloidosis: case report

Respiratory amyloidosis is a rare disease that occurs in three forms: tracheobronchial, nodular parenchymal and diffuse parenchymal involment. Tracheobronchial amyloidosis is characterized by focal or diffuse deposition of amyloid in the submucosa of the trachea and proximal bronchi. Herein, we report a case of diffuse tracheobronchial amyloidosis with plain radiography and thorax computed tomography findings.
