Shockwave treatment of ureteric stones in situ with second-generation lithotriptor

During a 17-month period we treated in situ 334 patients with ureteric stones with a second-generation electromagnetic lithotriptor. Anxiety and discomfort were relieved with diazepam and pethidine chloride only. Ureteral stenting was used in 8.1% of upper, 36.4% of mid- and 5.7% of lower ureteric stones. The retreatment rate was 15%, but no patient had more than 3 sessions. The success rate of the treatment at 3 months was 88% for upper, 65% for mid- and 83% for lower ureteric stones. Open surgery had to be performed in 5 cases and ureteroscopies in 6 cases.     

Pregnancy and uncomplicated vaginal delivery only 13 months after cardiac transplantation (case report)

Summary Background Pregnancy is prossible in female patients who underwent cardiac transplantation but is associated with unpredictable risks. Methods A 23-year old female patient underwent cardiac transplantation because of dilatative cardiomyopathy. Results Against our advice, she became pregnant 4 months after transplantation. Following an uneventful pregnancy, spontaneous vaginal delivery occurred 13 months after transplantation. The patient gave birth to a healthy new-born in good physical condition. Thereafter, the patient refused to attend any further routine follow-up control. 9 months after delivery, the patient was admitted to hospital in severe cardiac shock. Biopsy showed a serious, acute rejection which was treated with a course of methylprednisolone. Clinically, the patient recovered within 1 week, but died from acute myocardial infarction 1 day after discharge from hospital. Conclusions Only women without a history of rejection episodes, with good kidney function, good graft function, and high compliance should be counselled to become pregnant.      

The stimulant effect of modafinil on wakefulness is not associated with an increase in anxiety in mice

Modafinil is a new drug used in the treatment of narcolepsy. Its administration in mice induced a dose-dependent increase in locomotor activity. The effects of modafinil were compared with those of dexamphetamine on three tests that assessed the anxiety level (drugs were used at doses which induced a roughly similar stimulation of locomotor activity). Dexamphetamine increased the latency of exploration of a white compartment, increased thigmotaxis in an open-field and decreased the time spent in the open arms of an elevated plus-maze. None of these responses was significantly modified by modafinil. We conclude that modafinil does not share the anxiogenic effects of dexamphetamine.     

Meniscal transplantation using fresh and cryopreserved allografts. An experimental study in goats.

A comparative study of three subgroups of meniscal transplants was undertaken in the goat model: Group 1 (autograft) involved removal and immediate reimplantation of the meniscus; Group 2, fresh meniscal allografts; and Group 3, cryopreserved (30 days) meniscal allografts. Six months after surgery, tissues were evaluated for gross degenerative changes, proteoglycan concentration (as assessed by uronic acid), water content, vascularity, histology, and cell viability. The contralateral knee served as control for all comparisons. There was no statistical difference in the amount of arthritis present and all transplants demonstrated an essentially normal peripheral vascularity compared to controls. Sections revealed reduced numbers of cells in the central portions of the transplanted menisci and these viable cells demonstrated different behavior in multiplication in tissue culture compared to contralateral controls. Grossly and microscopically, the implanted menisci differed little from the controls. The measurement of proteoglycan concentration and water content of the transplanted meniscal cartilage suggest alterations that may affect the long-term mechanical properties. The autograft specimens showed the water content was very slightly increased (3% to 6%), while the proteoglycan concentration was increased (42% in terms of uronic acid). In contrast, the water content of the fresh allograft group and the cryopreserved group was increased 12% to 24%. Proteoglycan concentration in these groups was decreased up to 56% in portions of some menisci compared to controls. Fresh and cryopreserved meniscal allografts showed peripheral healing, revascularization, cellularity, and incorporation, and grossly appeared good at 6 months in the goat model. The biochemical changes in the extracellular matrix at 6 months raises questions on the long-term function of these transplanted menisci.     

Sonographic characteristics of epidermoidcyst of testicle

The ultrasonographic characteristics of an epidermoid cyst of the testicle are presented. Since these, findings are similar to other published case reports, preoperative sonographic diagnosis of this lagon may be possible.     

The Future of Clinical Psychology: Board Certification

The present article presents the future of clinical psychology board certification. With the increasing specialization in the field of professional psychology and the generic nature of state licensure, clinical psychology as a specialty will develop into a specialty area in a similar fashion as have specialties in medicine. A brief history of board certification in professional psychology by the American Board of Professional Psychology is reviewed and the process of becoming board certified in either clinical psychology or clinical child and adolescent psychology is discussed.
