Abstract. Adrenocortical adenoma is the most common cause of primary hyperaldosteronism. Most tumours are small, less than 2 cm in diameter and, therefore, their localization may be difficult. We have compared two different methods, adrenal scintigraphy (AS) and computed tomography (CT) in the differential diagnosis of 12 patients with primary hyperaldosteronism. AS was performed using either [131I]cholesterol or 6-iodomethyl-19-norcholesterol during dexamethasone suppression. Of the patients, five showed a normal CT and symmetrical uptake of the isotope as AS. They were considered representative of bilateral hyperplasia. All showed good therapeutic response to spironolactone. Seven patients had an adrenocortical adenoma verified at operation. The CT finding indicated a tumour in five patients. This was correct in four, but in one patient the adenoma was found in the contralateral adrenal gland. In two patients with an adenoma, CT was considered normal. AS correctly indicated the tumour in all seven patients. The uptake was unilateral in six, and bilateral but clearly asymmetrical in one patient. The results indicate that AS is superior to CT in the pre-operative localization of aldosteroma. Although CT remains the primary method for the investigation of these patients, AS should be applied always when CT does not unequivocally indicate the presence and localization of an adrenal tumour.

Renal Tumours

The responsibilities of the radiologist in the diagnosis of urinary tract neoplasms are discussed: a strong plea is made for the routine use of pyelography in all cases in which renal tumour is suspected, and it is suggested that too much reliance is placed on the excretion method alone. From the radiological viewpoint, renal tumours may be considered in the following three groups: (1) Parencymal tumours. (2) Tumours of renal pelvis. (3) Extrarenal tumours resembling renal tumours on clinical examination. The radiological signs which may be found in each group are described in detail, including the signs from plain radiography, instrumental pyelography, and excretion urography. The significance of non-excretion in small renal tumours receives attention. It is suggested that this is a sign of renal vein neoplastic thrombosis. The characteristics of osseous metastases from carcinoma of the kidney are considered with illustrative examples. Neoplasms of the ureter and their differential diagnosis are considered.

Microscopic Diagnosis

The broadest application of transmission electron microscopy (EM) in diagnostic medicine is the identification of tumors that cannot be classified by routine light microscopy. EM is useful in the evaluation of approximately 10% of human neoplasms, but the extent of its contribution varies considerably. It may provide a specific diagnosis that can not be reached by other means, but in contrast, the information obtained from ultrastructural study of some 10% of tumors does not significantly add to that available from light microscopy. Most cases fall somewhere between these two extremes: EM may correct a light microscopic diagnosis, or serve to narrow a differential diagnosis by excluding some of the possibilities considered by light microscopy. It is particularly important to correlate the EM findings with data from light microscopy, clinical examination, and other diagnostic procedures.

Healthcare professionals require a thorough understanding of stuttering since they frequently play an important role in the identification and differential diagnosis of stuttering for preschool children. This paper introduces The Preschool Stuttering Screen for Healthcare Professionals (PSSHP) which highlights risk factors identified in the literature as being associated with persistent stuttering. By integrating the results of the checklist with a child’s developmental profile, healthcare professionals can make better-informed, evidence-based decisions for their patients.

Threshold Duration

Previous findings on the threshold for tones as a function of their duration have suggested that such functions may be systematically affected by sensori-neural hearing losses of cochlear origin. The present series of investigations was designed to explore this relation further and to determine also whether the amount of hearing loss present has any effect upon the results which are obtained. Preliminary studies were also carried out on a conductively impaired listener to indicate whether hearing losses of this type affect the threshold-duration function. The results indicate that the threshold-duration function is systematically affected by sensori-neural hearing losses of cochlear origin. This effect is manifested by a progressive shortening of the time constant relating threshold to duration and is not uniquely related to the amount of hearing loss present. The results obtained from the conductively impaired listener suggested that this type of hearing loss has no effect on the threshold-duration function, thereby implying that such functions may contribute significantly to the differential diagnosis of auditory disorders.

Abstract Complex regional pain syndrome (CRPS) is a controversial, ambiguous, unreliable, and unvalidated concept that, for these very reasons, has been justifiably ignored in the “AMA Guides Library” that includes the AMAGuides to the Evaluation of Permanent Impairment (AMA Guides), the AMA Guides Newsletter, and other publications in this suite. But because of the surge of CRPS-related medicolegal claims and the mission of the AMA Guides to assist those who adjudicate such claims, a discussion of CRPS is warranted, especially because of what some believe to be confusing recommendations regarding causation. In 1994, the International Association for the Study of Pain (IASP) introduced a newly invented concept, CRPS, to replace the concepts of reflex sympathetic dystrophy (replaced by CRPS I) and causalgia (replaced by CRPS II). An article in the November/December 1997 issue of The Guides Newsletter introduced CRPS and presciently recommended that evaluators avoid the IASP protocol in favor of extensive differential diagnosis based on objective findings. A series of articles in The Guides Newsletter in 2006 extensively discussed the shortcomings of CRPS. The AMA Guides, Sixth Edition, notes that the inherent lack of injury-relatedness for the nonvalidated concept of CRPS creates a dilemma for impairment evaluators. Focusing on impairment evaluation and not on injury-relatedness would greatly simplify use of the AMA Guides.
