Treatment of a constellation of inappropriate sexual and social behaviors in a 20 year old man with Down's Syndrome

In 1983, a Down's Syndrome male (I.Q. 72) AB who resided in a community residence was charged by local police with Exposing his genitalia, as a result of an incident of exhibitionism. Upon investigation by the New Jersey Division of Mental Retardation (a State of New Jersey Agency now named the New Jersey Division of Developmental Disabilities), it was found that AB had a constellation of inappropriate sexual and social behaviors. A treatment plan was designed by a State Psychologist, a private Psychologist, a State Special Educator, a State Social Worker, and residential staff, with the full cooperation of AB's parents. The treatment approach combined traditional psychotherapy, a token economy plan, and vigorous social skills training. AB has been followed for 7 years and the treatment plan has been modified a number of times, as AB's behavior has continued to improve. Over the 7 years, AB has not had any more arrests on sexual charges and his overall social behavior has shown marked improvement.     

Effect of chronic clonidine treatment on the turnover of noradrenaline and dopamine in various regions of the rat brain

Summary The turnover of noradrenaline (NA) and dopamine (DA) was estimated in various rat brain regions by measuring the depletion of the amines after inhibition of their biosynthesis by -methyltyrosine. Acute treatment with clonidine (0.1 mg/kg) reduced NA turnover in the brain stem, hypothalamus and rest of the brain but had no effect on DA turnover in the corpus striatum and rest of the brain. After chronic clonidine treatment (0.1 mg/kg, twice daily for 15 days), NA turnover was not affected by an additional injection of clonidine in the brain stem or in the hypothalamus but was still markedly reduced in the rest of the brain. In addition, DA turnover was reduced in the corpus striatum and rest of the brain, an effect which was also observed after a single injection of a high dose of clonidine (1 mg/kg). These findings suggest that a chronic administration of clonidine may cause regionally differential changes in the sensitivity of central NA receptors.     

Surgical management of recurring or metastatic thyroid cancer

The surgical oncologist is sometimes confronted with a patient who was surgically treated for cancer of the thyroid gland and now has recurrent disease. In most instances, additional surgical treatment is indicated. The magnitude of surgery is primarily determined by the amount of tissue removed at the original operation. Surgery for recurrent disease may include completion of total thyroidectomy with dissection of lymphatic tissues in the thyroid compartment or/and neck dissection, preferably modified. Several clinical situations are outlined and discussed.     

Gastrostomy and oesophagoplasty with a flap from the greater curvature of the stomach as stages of surgical and combined treatment of cancer of the thoracic oesophagus

Four-hundred fifty-eight patients with cancer of the oesophagus were subjected to revisional laparotomy. Metastases into subphrenic lymph nodes were registered in 24% of the cases with a tumor in the bronchial segment; 42% with tumor in the subbronchial segment; 48% with tumor in the retropericardial segment; 71% with tumors in the sub-, intra-, and supraphrenic segments of the oesophagus. In 345 cases, laparotomy was followed by tube gastrostomy (Beck—Carrel method) with two operative deaths. Fifty-six patients in good condition with a small tumor in the middle part of the oesophagus (≤5 cm) without any abdominal metastases were subjected to primary oesophagoplasty: a 30–32-cm tube was formed out of the greater curvature of the stomach and placed retrosternally; gastrostomy was performed on the level of the thyroid cartilage (without any operative deaths). In two weeks, extirpation of the thoracic part of the oesophagus (with preoperative irradiation) was performed on patients with no abdominal metastases. Then the patients with primary oesophagoplasty were subjected to oesophago-gastrostomy of the neck. From six to 12 months following the combined treatment, the gastrostomy tube of 45 patients was lengthened to 30–32 cm and used for retrosternal oesophagoplasty (six operative deaths). Oesophagoplasty was performed on 14 patients during the extirpation of the oesophagus (six operative deaths).     

Malignant tumors of the nasopharynx

One hundred and twenty patients with malignancy of the nasopharynx were reviewed. The most common presenting symptoms of this disease were cervical mass and hearing loss. Neoplasm occurred three times more frequently in males than in females. Cranial nerve dysfunction was present in 17.5% of patients at the time of initial evaluation. The overall 3- and 5-year determinate survival for the entire series of nasopharyngeal malignancies was 38.9, and 27.0%, respectively. Nonsquamous cell malignancies demonstrated a better 5-year survival (42%) than squamous cell and undifferentiated neoplasms (24%). The presence of cervical metastases offered a poorer prognosis. A 39.6% 5-year survival was recorded for patients without nodal disease. Massive lymphadenopathy or bilateral cervical metastases forecasted an ominous 5-year survival of 13.6%. Control rate was greatest among patients with tumors restricted to one area of the nasopharynx and without regional metastases. The 5-year survival of such patients was 71.4% compared to 13.3% for patients having tumor extension beyond the nasopharynx producing cranial nerve impairment or bone erosion.     

The rotational component in the dynamics of the C2–3 spinal segment

Summary The technique of the PA axial projection of the arches of the upper cervical vertebrae into the occipital foramen and the normal findings, are described. The influence of maximum forced anteflexion at the craniocervical junction and rotation of the head on the relations of atlas and axis is demonstrated. It seems that in this position rotation at atlasaxis level is restricted and partly transmitted to the C_2–3 segment. Thus, selective clinical examination of the rotational component of the dynamics at C_2–3 can be achieved and the pathological restrictions of movement can be assessed.     

Treatment of vertebro-basilar aneurysms

Summary In continuation of investigations on classification and treatment of ICA-system aneurysms and on the classification of the vertebro-basilar-system aneurysms their treatment has been discussed. Based on this, classification has been improved and the preoperative topographic diagnosis and the choice of approach have been influenced. The operative management has been pioneered by C. G. Drake, who described the technique in detail on hand of his enormous experience with 469 aneurysms of the vertebro-basilar-system (13). The necessity of a normal aneurysm neurosurgeon treating such aneurysms requires certain modifications of indication, approach and dissection. In a personal statement based on 35 VB-aneurysms (6 per cent) the strategy of handling these aneurysms has been developed (45). Microsurgical technique is regarded absolutely necessary. Thetransoral transclival access to aneurysms of the lower clivus should be included in the approaches, similarly to the transsphenoidal operations. It facilitates the direct isolation in a very difficult region.Electrothermic dissection of the aneurysm diminishes the risk of rupture during the isolation of the sack and facilitates the isolation of the neck. The statistics of Drake provide full data for the prognosis of these aneurysms. It is to note that in the recent time the results reported from different centres became more and more similar. The embolization of large bulbous or spheric and giant aneurysms by inflatable balloon-technique possibly may replace some risky direct or indirect operations.

Zusammenfassung In Fortsetzung unserer Untersuchungen über die mikrochirurgische Klassifikation und Behandlung der Aneurysmen des A. carotis interna-Systems, sowie die Klassifikation der Aneurysmen des Vertebro-Basilaris-Gebietes befaßt sich der Beitrag mit der Therapie letzterer. Die moderne Klassifikation und parallel dazu die präoperative angiographische Diagnostik haben die Wahl der Craniotomie und des direkten Zugangs zum Aneurysma unmittelbar beeinflußt. Die operative Behandlung ist im wesentlichen das Werk eines Mannes — Charles Drake — der die Technik anhamd seines großen Krankengutes von derzeit 469 Fällen im Detail beschrieben hat. Die Notwendigkeit für den normalen Aneurysma-Neurochirurgen, derartige Aneurysmen zu behandeln, erfordert nach meiner Überzeugung gewisse Modifikationen der Indikation, des Zuganges und der Präparation. In einer persönlichen Stellungnahme, die sich auf eine Erfahrung von 35 Aneurysmen des Vertebro-Basilaris-Gebietes stützt (6%), werden die Prinzipien des Vorgehens erläutert. Die mikrochirurgische Technik ist unerläßlich.Dertransorale transclivale Zugang sollte für bestimmte Aneurysmen der A. basilaris ebenso durchgeführt werden, wie der transsphenoidale Zugang für Hypophysenadenome selbstverständlich geworden ist. Er erleichtert die direkte Freilegung in dem sehr risikoreichen Gebiet von Brücke und Hirnnerven.Dieelektrothermische Dissektion verringert das Risiko der Ruptur während der Präparation und erleichtert die Isolierung des Aneurysmahalses.Drake's Statistik enthält alle Einzelheiten über die Prognose der verschiedenen Vertebro-Basilaris-Aneurysmen als Maßstab für das eigene Resultat. Erfahrungen der letzten Jahre aus verschiedenen Kliniken zeigen, daß die Ergebnisse sich mehr und mehr angleichen.DieEmbolisation großer bulböser und sphärischer Aneurysmen und der Riesenaneurysmen durch die Ballon-Technik erscheint geeignet, risikoreiche direkte oder indirekte Operationen zumindest teilweise zu ersetzen.

     

Effect of acute and chronic treatment of tandamine,a new heterocyclic antidepressant,on biogenic amine metabolism and related activities

Summary The effects of tandamine, a clinically effective heterocyclic antidepressant, administered either acutely (10 mg/kg i.p) or chronically (10 mg/kg i.p. daily for 21 days) on biogenic amine uptake and metabolism in the rat were determined and a comparison with desipramine was made. Tandamine, similarly to desipramine, blocked norepinephrine (NE) uptake in rat brain and heart following both acute and chronic administration. No effect of tandamine on dopamine (DA) or serotonin (5-HT) uptake was observed. Both drugs lowered endogenous brain NE when given chronically but not acutely. In contrast, no such effect on brain DA and 5-HT or heart NE was observed. Tandamine, like desipramine, administered chronically prior to an intraventricular injection of ³H-NE, produced increases in the decline of ³H-NE as indicated by decreased ³H-NE with increased levels of ³H-normetanephrine in brain stem of rats, suggesting an increased turnover of NE. No such effect was observed following acute treatment. Both drugs increased the behavioural effects of L-Dopa following an acute oral administration, with tandamine appearing superior to desipramine at the lower dose examined (10 mg/kg). Tandamine was 57–833 times less effective in binding to rat brain muscarinic receptors than desipramine, imipramine, butriptyline and amitriptyline, respectively. Thus, tandamine affects biogenic amine mechanism following either acute or chronic administration in a fashion similar to desipramine, but unlike desipramine, it exhibits relatively little anticholinergic properties, a further indication of the potential use of tandamine in the treatment of human depression, particularly where an increase in drive is desired.     

Long-term treatment with β-blockers after myocardial infarction

Summary 162 patients discharged from hospital after myocardial infarction were randomly allocated to two groups, one received alprenolol 400 mg daily and the other served as the control. The period of follow-up was two years and all other treatment given was standardized. The two groups did not differ with respect to risk factors for myocardial infarction, the course of the acute infarct or treatment during follow-up. After two years one patient in the group treated with alprenolol had died suddenly as compared to nine in the control group. During the same period four fresh infarcts had occurred in the alprenolol group compared to 15 in the control group. Both these differences were statistically significant. Only four patients were obliged to discontinue -blocker treatment because of suspected side-effects. Long-term post-infarction treatment with -blockers appears to be an effective form of secondary therapy without serious side-effects.     

Supersensitivity of cortical neurones of the rat to acetylcholine and L-glutamate following chronic morphine treatment

Summary The effect of microelectrophoretically applied L-glutamate and acetylcholine on discharge activity of cortical neurones was studied in naive and in morphine-tolerant/dependent rats. The thresholds for increase in discharge activity elicited by these 2 putative neurotransmitters were 3 times lower in the tolerant/dependent rats than in the naive rats, indicating the development of supersensitivity.
