Locations of occipital EEG electrodes verified by computed tomography.

Aluminum markers placed according to the 10-20 system (at Cb, O, P, Fp and M sites) and the Queen Square system (at MF, LO, MO and RO) were imaged using the computerized tomography technique in 32 individuals with no skull deformities or brain pathology. There was a small, but reliable, placement error of midline markers with regard to the longitudinal fissure which was maximal for Cbz and Oz. This asymmetry was attributed to variance in the anatomy of the occipital bone and cranio-cerebral topography that cannot be predicted from location of the inion. In over 30% of the sample, difficulties in defining the inion further contributed to location errors. In 11 of 12 subjects there was a reliable asymmetry of the intraparietal sulcus with the left sulcus located about 0.5 cm more medially. Therefore, no matter how perfectly an electrode is aligned with the midline, the lateral electrodes cannot be placed over truly symmetrical sites due to sulcal variance.

Radiological colpocephaly: a congenital malformation or the result of intrauterine and perinatal brain damage.

The term colpocephaly, meaning disproportional enlargement of the occipital horns of the lateral ventricles, was considered in the past to be a distinct congenital malformation acquired in early intrauterine life. During the last few years several cases were reported in whom a variety of intrauterine and perinatal causes could be associated with this radiological picture. We report on 9 children with radiological colpocephaly in whom intrauterine and/or perinatal injury to the developing brain seemed to be the cause of colpocephaly. It is evident from our observations that "radiological colpocephaly" is a non-specific finding caused frequently by CNS damage acquired during intrauterine and perinatal life.

Otitis media with effusion as a presenting symptom of chronic sinusitis.

Otitis media with effusion was the presenting symptom in 23 per cent of patients suffering from chronic sinusitis. The inter-relationship between chronic sinusitis and otitis media with effusion was studied in 29 patients. Endoscopic evaluation of intranasal structures including sinus ostia and Eustachian tube orifices was carried out. We further suggest that otitis media with effusion is not a separate entity but a presentation of sinus disease, predominantly of the ethmoid system. Patients with otitis media with effusion should be evaluated for sinusitis and vice versa. The value of careful nasendoscopy is demonstrated.

Pyogenic thyroiditis due to branchial pouch sinus.

Suppurative thyroiditis due to branchial pouch sinus is a rare disease, affecting children and young adults. It presents as an abscess in the lower lateral neck, usually on the left side. Suppurative thyroiditis can be suggested by ultrasound, radionuclide scintigraphy or CT scan, but the diagnosis can only be established by barium swallow showing the sinus from the apex of the pyriform sinus to the perithyroid region. Complete surgical excision of the sinus is essential. Two patients are presented and the role of the various imaging modalities in the diagnosis is discussed.

Pediatric update #8. Acute hematogenous osteomyelitis in children. Long-term results of surgical treatment.

A retrospective review (1970-1982) of the clinical experience of 68 children with acute hematogenous osteomyelitis (AHO) is presented. Analysis of the epidemiologic, clinical, laboratory, radiologic and bacteriologic findings is made. Our series was treated mainly by an aggressive primary surgical protocol which is described in detail. Seventeen percent developed chronic osteomyelitis. The role of surgery in the treatment of AHO is discussed. It is our belief that surgical treatment has definite advantages over the conservative regime and it remains our treatment of choice.

Staging cecal and ascending colon carcinoma with computed tomography.

Operable subserosal and transserosal and inoperable cecal and ascending colon carcinomas can be differentiated by computed tomography (CT). Invasion of the posterior peritoneal reflection produces recognizable changes on CT, which, with or without adjacent muscle invasion, are indicative of tumor nonoperability.

Transient protein-losing gastropathy (Menetrier's disease) in childhood.

Two cases of transient protein-losing gastropathy (PLG) or Menetrier's disease in childhood are described. Both cases presented with an abrupt onset of edema due to hypoalbuminemia and were diagnosed by an upper gastrointestinal series. One of the cases was further diagnosed and followed by ultrasound. We believe that this is the first description of the ultrasonic picture of transient PLG in children. In both cases complete recovery was evident after a few weeks.

Superior mesenteric artery syndrome presenting as an anorexia nervosa-like illness.

Anorexia nervosa is often overdiagnosed in adolescent females with anorexia and extreme weight loss. In some cases, an anorexia nervosa-like illness is due to a treatable organic disorder. We describe a 16-year-old female with anorexia, vomiting, extreme weight loss, and amenorrhea who was referred as an anorexia nervosa case and was subsequently found to have superior mesenteric artery syndrome that was causing a duodenal obstruction. Conservative treatment with oral hypercaloric liquid feeding resulted in optimal weight gain and complete recovery. This syndrome should be considered in adolescents with an anorexia nervosa-like illness associated with vomiting and postprandial epigastric discomfort.

Surgical management of the cleft sternum.

Cleft sternum is a rare disturbance of unknown origin in the normal central midline fusion. Three cases of upper cleft sternum are reported here, one associated with a pericardium to the skin sinus tract. Surgical correction of this anomaly in the neonatal period is advised, whether the infant is symptomatic or not. Simple closure of the defect during the first month of life avoids the more complex reconstruction necessary in older children.

Inflammatory pseudotumor of the liver.

Inflammatory lesions in the liver simulating tumor formation are rare. Eleven cases have so far been reported in the literature, most of them in recent years. We present an additional case of an "inflammatory pseudotumor" in a 17-year-old male. The inflammatory pseudotumor should be kept in mind in the differential diagnosis of hepatic space-occupying lesions.

Fracture of the clavicle in the newborn. An ultrasound diagnosis.

Forty-one cases of clavicle fracture in newborn babies were examined by both radiographic and ultrasonic methods. No substantial difference has been found between these two modalities. It is suggested that ultrasound should be the procedure of choice in the diagnosis of clavicle fracture. This is especially true in those cases where impaired movement of the arm is the only clinical sign.
