The reasons for failure of the initial exploration and the results of reoperation were analyzed in 53 patients with a diagnosis of primary hyperparathyroidism, 29 of whom were referred after initial operations elsewhere. Seventy-nine reoperations were performed. Sternotomy was used in 15 patients, and in retrospect was necessary in only 5. There was no(More)
Considering the general impression of an increased number of patients with acute renal colic, the frequencies of roentgenologically verified ureteral and kidney calculi in a Swedish urban district have been studied for the periods 1953-55 and 1968-70. In a material of 986 outpatients (793 men and 193 women) we have proved an increase in incidence for upper(More)
Single Photon Emission Computed Tomography (SPECT) has been used to examine the spine in a prospective long-term study with the aim of assessing the value of bone scintigraphy in the detection and diagnosis of ankylosing spondylitis (AS). Sites of increased uptake of 99Tcm-MDP were observed in three of the eleven patients examined so far. By carefully(More)
The present study explored the prevalence and descriptive characteristics of hyperacusis, defined as unusual intolerance of ordinary environmental sounds. Two ways of collecting data were used in the study: the first was a postal survey of a random sample, to which 589 responded (59.7% response rate); the second was the internet, and 595 self-recruited(More)
Osteopenia, sometimes with compression fractures of the spine, is a side-effect of long-term heparin treatment. The frequency is unknown. In this study, 70 women were given subcutaneous heparin as therapy for, or prophylaxis against, thromboembolism during pregnancy. All, except two, were examined by X-ray of the spine and hip first week post partum. The(More)
Graphene, a true two-dimensional material with extraordinary mechanicaland electronic properties, is thought to be ideal for nanoelectromechanical systems (NEMS), like massand force sensors. Here, we present two different ways to fabricate suspended graphene for the intended use in future NEMS applications. The fabrication schemes do not require transfer of(More)
Fifty two patients with juvenile chronic arthritis (JCA) and 22 patients with arthritis of short duration (transient arthritis, TA) were studied in a follow up investigation. Nineteen (37%) of the patients with JCA had peripheral arthritis or sequelae in the form of contractures at follow up, and in addition one patient was treated with corticosteroids. In(More)
