The evaluation of ear canal, middle ear, temporal bone, and cerebellopontine angle masses in infants, children, and adolescents.

Ear canal, middle ear, temporal bone, and CPA angle masses (except for cholesteatomas) are rare in the pediatric population. The physician needs to have a high degree of suspicion for such lesions if a child presents with ear pain unrelated to infection or otorrhea that fails to improve after treatment. A precise diagnosis needs to be made in these children and also in those with hearing loss, vertigo, and facial paralysis. The most useful imaging procedures for ear, temporal bone, and CPA masses are CT and MR imaging. With a suspected vascular lesion, a definitive diagnosis usually can be made by an imaging procedure or angiography. In all cases of mass lesions, except for some aneurysms and infections, a tissue diagnosis must be secured.

An outbreak of waterborne cryptosporidiosis caused by post-treatment contamination.

An outbreak of waterborne cryptosporidiosis affecting 27 persons, diagnosed stool positive, occurred in Ayrshire in April 1988. Twenty-one in 27 confirmed cases required some form of fluid replacement therapy. Local general practitioners indicated a two- to fivefold increase in diarrhoeal disease during the outbreak, and following enquiries made by Environmental Health Officers it became apparent that many hundreds of people had suffered a diarrhoeal illness at that time. Cryptosporidium spp. oocysts were detected in the treated chlorinated water supply system, in the absence of faecal bacterial indicators. Oocyst contamination of a break-pressure tank containing final water for distribution was the cause of this waterborne outbreak. An irregular seepage of oocyst-containing water, which increased during heavy rains, was the cause of the break-pressure tank contamination, rather than a failure of the water-treatment processes. The waterborne route should be considered when clusters of cryptosporidiosis-associated with potable water occur. Waterborne cryptosporidiosis can occur in the absence of other faecal indicators of contamination.

Hyperandrogenism, insulin resistance, acanthosis nigricans, and systemic lupus erythematosis associated with insulin receptor antibodies.

We report a young woman with systemic lupus erythematosis (SLE) who developed diabetes secondary to extreme insulin resistance, associated with severe hyperandrogenism and acanthosis nigricans. Her insulin resistance was found to be associated with high titers of insulin receptor antibodies. The hyperandrogenism has been favourably influenced by cyclical treatment with cyproterone acetate and ethinyl oestradiol, but the insulin resistance and acanthosis nigricans have remained unmodified after 15 months of follow up.

Trigeminal schwannoma in a child.

A 5-year-old girl presented with headache, vomiting, flushing, ptosis, and paroxysmal tachycardia. The neurological findings were partial motor and sensory left trigeminal palsy, left conductive hearing defect, and left cerebellar deficit. The radiological and neuropathological findings were typical for trigeminal schwannoma, which is rare in childhood. The present patient is the youngest yet recorded.

Cervical neurogenic tumors presenting as thoracic apical masses in infants and children.

Seven cases of cervical neurogenic tumor presented in an almost identical manner roentgenographically; a polypoid extrapleural mass at the lung apex. The association of neuroblastoma with Horner syndrome and heterochromia of the irides is mentioned. Characteristic roentgen appearance should be appreciated due to good prognosis of cervical neuroblastoma with prompt therapy.
