A unique set of identical twin boys with spinal and intracranial meningiomas is described. Three distinct spinal tumours and one intracranial one were removed surgically. One intracranial meningioma has been symptomless, so far. The red cell and leucocyte groups of the two patients were found to be identical, and the probability of their being monozygous was estimated from these data as being 0...

Hereditary hyperparathyroidism, occurring as an isolated endocrinopathy was first described by Goldman and Smyth in 1936. They described primary hyperparathyroidism in two siblings. Jackson and Boonstra (1967) collected 21 families with 107 hyperparathyroid members from the literature, including eight unrelated families of their own, all discovered in a single centre over a 10-year period. This...

?n Britain and in the U.S.A. for detection of symptomless or latent pulmonary tuberculosis, but most of the work of this type was at first confined to the services. In 1941, in view of the increasing incidence ?f tuberculosis in war time, the Medical Research Council appointed a committee of enquiry, and next year this committee issued a report, one of its proposals being for the controlled use...

The incidence of duplication of the urinary tract has variously been estimated by different authors to be between the extremes of 0-6% (Campbell, 1951) and 6% (Thompson and Amar, 1958) of individuals. The anomaly may remain symptomless and undetected throughout life, but it carries a predisposition to pathological complications, the most severe and urgent of which occur in early childhood, at w...

The action of metoclopramide on gastroduodenal motility was studied in 23 subjects: eight symptomless volunteers and 15 patients with varying upper abdominal conditions. The response depended on the basal contraction pattern before the drug was given, irrespective of the clinical diagnosis. The size of the antral contractions was consistently increased and the duodenal contractions became more ...

Over a period of nine months 203 cases of urethral gonorrhoea were seen in 188 men. In 36 (17%) of the cases there were no symptoms, and in 14 (7%) the symptoms were considered so mild that the patients thought medical care was unnecessary. The symptomless patients and those with mild symptoms were found only as a result of efficient contact tracing. This high incidence illustrates the importan...

Chlamydia trachomatis was isolated from the endometrial cavities of three out of 19 women with positive cervical cultures, who were all symptomless sexual contacts of men with non-gonococcal urethritis (NGU). C trachomatis was recovered from the endometrial cavities of four out of 14 women with pelvic inflammatory disease (PID), three of whom had positive cervical cultures. Although endometrial...

Ectopic eruption of teeth in non-dental sites is a rare phenomenon; It may be symptomless but is more commonly associated with inflammatory symptoms. It can present in a variety of ways such as chronic or recurrent sinusitis, sepsis, nasolacrimal duct obstruction, headaches, ostiomeatal complex disease and facial numbness. The treatment of choice is surgical excision which is mostly carried out...

in this study, feasibility of upgrading and retrofitting municipal wastewater treatment plantswas investigated at laboratory scale using moving bed biofilm reactor (mbbr) process. for this purpose,an aerobic pilot was operated for nearly one year in different conditions, in which a moving bed carrier with aspecific biofilm surface area of 500 m2/m3 and a filling rate of 60% was utilized. system...
