Endodontics in the '90s: old dogma and new tricks ... can we be re-taught?

Endodontics has gone through many changes in the past several years. Electronic apex locators and surgical microscopes have taken a lot of the guess work out of doing root canal. Digital radiograpy has expanded our diagnostic abilities. Ultrasonic intrumentation and the advent of new filing systems have increased the efficacy of canal cleaning. There have also been some major refinements in how we can now obturate canals. Apicoectomies can now be performed with refined ultrasonic root end preparations, and we have increased our ability to better seal root ends with new filling materials. The result is that endodontic procedures can now be performed more expediently and with a more predictable outcome. This article is written from the perspective of a full-time practicing endodontist, and describes the various changes occurring within the specialty of endodontics.

Vascularity of the neonatal femoral head: in vivo demonstration with power Doppler US.

PURPOSE: To detect the intrinsic blood supply of the unossified neonatal femoral head in vivo by using power Doppler ultrasound (US) and to ascertain whether a reduction in blood flow could be demonstrated with hip abduction. MATERIALS AND METHODS: One hip of 13 neonates was examined with power Doppler sonography. After vessels within the femoral head were identified, the thigh was slowly abducted and the angle at which flow became undetectable was recorded. Spectral Doppler tracings were obtained in all subjects. RESULTS: Intrinsic blood flow of the femoral head was demonstrated in all subjects. Flow became undetectable during hip abduction in 11 of 13 neonates and reappeared during adduction. The angle at which flow became undetectable varied from 60 degrees to 85 degrees. Spectral Doppler signals demonstrated a mixed arterial and venous trace. CONCLUSION: Power Doppler US provides a simple real-time assessment of the femoral head blood supply. This may prove helpful in identifying neonates at risk of avascular necrosis, a complication of treatment of hip dysplasia with abduction hip restraints.

The use of ultrasound-guided cutting-needle biopsy in the neck.

Histological analysis of an abnormal neck mass has traditionally required an excision biopsy under general anaesthetic. We evaluated the safety and accuracy of a new spring loaded cutting-needle for obtaining tissues cores of neck masses under ultrasound (US) guidance. Sixty biopsies were performed on an outpatient basis under local anaesthesia in 52 patients referred with a neck mass. Patients ranged in age from 10 months to 89 years and masses varied in size from 5 mm to 5 cm. Fifty-eight of the 60 biopsies provided a diagnostic histological specimen. Of the remaining two patients, one required open biopsy and the other returned for a second needle biopsy. All five cases of lymphoma were correctly diagnosed on needle biopsy; in three cases full tumour sub-classification was possible but in two patients an open biopsy was subsequently required. In 49 patients the needle biopsy obviated the need for a surgical biopsy for diagnostic purposes, although in 12 cases a therapeutic excision biopsy was performed. Apart from one subclinical haematoma, visualized on US, there were no immediate or delayed complications. In all patients, the histological diagnosis was compatible with subsequent clinical, radiological, surgical or autopsy findings. Cutting-needle biopsy of neck masses under US guidance is an effective and safe procedure which should be considered before resorting to routine surgery.

Post-traumatic stress disorder and the lost memory syndrome.

A number of different symptoms may result as the reaction to severe stress. It is unjustified to assume that specific disorders, such as bulimia, multiple personality, borderline personality, etc., are caused by specific early childhood trauma. Fadism is harmful to the patient and the medical profession.

Sonography in the evaluation of the male anterior urethra.

Contrast ascending urethrography is the technique most commonly used to evaluate the male anterior urethra. Sonography of the anterior urethra was prospectively evaluated in 24 consecutive referrals for conventional urethrography. In 11 patients both the sonographic and the contrast urethrograms were considered normal. Both studies demonstrated one or more strictures in nine patients but ultrasound also demonstrated periurethral cuffing in three of these. Sonography demonstrated a mucosal flap missed on the contrast study and also showed that suspected bubbles seen on the contrast study were true urethral filling defects. Diverticula were seen in three contrast studies. Two were demonstrated sonographically but the third, a shallow diverticulum in a patient with a complex stricture, was not seen on the sonogram. Mucosal irregularity was observed in five patients, and lack of urethral distensibility was demonstrated in a further five patients, by both techniques. Reflux into prostatic and Cowper's ducts could not be detected by ultrasound. Sonography offers advantages over conventional urethrography both in terms of abnormalities detected and convenience of the study.

An assessment of sonography in the diagnosis and management of neonatal renal candidiasis.

The renal sonographic findings in six cases of neonatal candidiasis and 13 cases previously reported in the literature are reviewed. Focal and diffuse parenchymal changes and obstruction due to mycetoma formation were frequent features. In the current series the sonographic changes were found to bear an inconstant relationship to the probable time of onset of the infection. In addition, apparent sonographic deterioration occurred in neonates well after adequate antifungal treatment was initiated. In view of the potential toxicity of systemic antifungal therapy, sonographic renal parenchymal changes are not considered an adequate indication for either its initiation or its continuation.

Dentinal sensation and hypersensitivity. A review of mechanisms and treatment alternatives.

Dentinal hypersensitivity has long been a dilemma of both dentists and patients. With teeth being maintained longer, there has been an increased demand placed upon the dentist to manage the sensitivity of cervically exposed dentin. There has been much written on this subject. The purpose of this review is to summarize the current concepts thought to be responsible in dentinal sensation, and to review and critique the various treatment modalities for dentinal hypersensitivity.

Frieda Fromm-Reichmann: a seminar in the history of psychiatry. I. Introduction.

From my very beginning in psychiatry, Frieda Fromm-Reichmann was one of my ideals. Her writing on psychotherapy, free of jargon and convolutions, made it possible to attempt treatment of even the very severely ill. She held forth the possibility of intervening in the life course of the schizophrenic, of understanding this person in distress and turning him in a new direction. She made her therapy a mutual adventure of therapist and patient as they explored a new realm and a new world.
