[Pain-sensation following classic neck-dissection (author's transl)].

Resulting neck-dissection surgery (including curative or conservative intervention) very complex pain-syndromes are next to losses of function at the top of complaints stated. The discussion of the case-reports of 242 patients with unilateral neck-dissection and the reexamination of 28 patients free of recurrence revealed several causes of head- and facial pain. The close relationship of functional disability and pain-sensation is discussed. The recommendation of elective neck-dissection - by critical indication - is supported. Resection of nervus accessorius may be necessary in some cases, immediate reconstruction by nerve sutures is recommended. By post-operative treatment the complaints often can be relieved.

Process measures in interventions for drug-abusing women: from coping to competence.

As a guide to the selection of process and outcome measurement in interventions with drug-abusing women, we have offered a model of fundamental coping processes. Three coping processes--reinforcer management, challenge management, and affect management--appear critical to women's competence and physical hardiness. When these processes go awry, substance abuse is a likely result. For successful recovery from substance abuse, good fortune or purposeful intervention must promote these coping processes. To measure the impact of any intervention with drug-abusing women, methods of assessing fundamental coping processes during intervention (process measures) and repeatedly after intervention (outcome measures) are needed. We have described multiple methods of measuring fundamental coping processes from diverse vantage points: self-report, behavioral observation, biochemistry, and physiology. We have discussed how these measures relate to the theoretical model. Finally, we have indicated measures favored and used in our longitudinal and intervention research on adolescent and perinatal substance abuse. The final set of measures, as summarized in the list of recommended process and outcome measures on pages 324-325, is somewhat lengthy because the process of intervention is complex. Given the financial and structural limitations of research in drug treatment settings, it may not be possible for a single investigator to employ all the recommended measures. An adequate research design would employ two measures from each of the domains outlined. If resources allow, more extensive measurement procedures would be possible.

[Value of studying pain in objective assessment of the clinical status of patients after spinal surgery].

The author demonstrates the role of algologic studies (projective Stewart's test scale), scales of verbal and visual analogs) in objective evaluation of the clinical status of patients who underwent spinal surgery for lumbar pains. Differences have been revealed in the algologic status of patients who suffered restricted interventions and complex decompression stabilizing operations with posterior spondylodesis.

[Management of radiation-induced injuries of the intestine].

Radiation-induced injury of the intestine (RII) is a chronic iatrogenic disorder which often necessitates complex surgical intervention. We describe our experience with the surgical management of 9 patients with RII, 8 of whom suffered injuries of the small bowel and 1 of the rectosigmoid. There were 3 deaths, 2 from postoperative complications of ongoing RII and 1 from recurrence of the original tumor. 3 of the survivors continued to suffer from complications attributed to active RII, while only 3 remained symptom-free during follow-up. Our study emphasizes the fundamental role of good nutritional support during the perioperative period in these patients. It also indicates the desirability of using nonirradiated bowel for the anastomosis, and of a bypass procedure instead of resection and primary anastomosis in cases of radiation-induced frozen pelvis. Creating a barrier between the peritoneal cavity and the lower pelvis by an omental flap or other means, should be considered in patients operated on for pelvic cancer who might need adjuvant radiotherapy. This procedure shields the bowel from the radiation field, thus hopefully reducing the incidence of RII.

[Methods to improve the delivery of hospital ophthalmological care to children in the Ukrainian SSR].

On the material of Children Eye Department the Filatov Institute, changes in the structure of eye pathology for the period of 1947-1989 are analysed. It is shown that for the last years, among all eye diseases, the incidence of inflammatory eye diseases fell to 7.5%. The incidence of eye traumas and their outcomes reaching 26.2% remained stable. The incidence of congenital pathology (35.4%) and new-formations in the eye (10.8%) with predominance of malignant tumors, complex pathology of oculomotor apparatus (23.5%) reached high values. Organization of centers, of ophthalmic microsurgery in children allowed to introduce into ophthalmological practice complex surgical interventions requiring special devices and instruments. Surgical activity of the Center of Ophthalmic microsurgery in Children on the basis of the Filatov Institute made up 84.5% in the last five years. In order to optimize the rendering of stationary ophthalmological aid to children, the authors consider it necessary to improve continuity between a microsurgical center and regional children eye hospitals, to increase qualification of children ophthalmologists, to create a Republic Center for Rehabilitation of Children with eye diseases on the basis of a sanatorium with a good ophthalmological equipment.

Future growth and development of hysteroscopy.

In less than two decades, hysteroscopy has evolved into a practical technique for the evaluation of the uterine cavity, with well-established indications such as evaluation of abnormal uterine bleeding and abnormal hysterograms as well as the treatment of intrauterine adhesions or the septate uterus, the removal of misplaced or embedded intrauterine devices, and the removal of submucous leiomyomas. As the use of hysteroscopy increases and more practitioners utilize it, new instrumentation and techniques are beginning to evolve, simplifying and facilitating not only a diagnostic examination, but also the more difficult and complex surgical interventions. Flexible endoscopes are being tested for possible use in the uterine cavity, and operative hysteroscopes with practical inflow and outflow accessory channels have been introduced. The accessory operative instrumentation has also been expanded and refined, and portable units for office examinations have been developed. The trend in the development of instrumentation is toward simplicity, effectiveness, and refinement in lenses with wider fields of view and accessory channels without compromising the total outer diameter of the endoscopes. As clinical applications expand as a result of increased use and proficiency in hysteroscopy, new applications undoubtedly will follow, such as closer study of the endometrium with and without additional magnification. This latter may permit a better understanding of the receptivity of the endometrium to the embryo, which may help in predicting successful nidations. Portable laser units with the capability to use the CO2 fiber undoubtedly will increase laser use through hysteroscopy, and in the near future, photodynamic therapy may become the best approach to the selective treatment of intrauterine lesions. The uterotubal junction will remain an attractive area for endoscopists to approach the fallopian tubes transcervically and eventually to accomplish tubal closure safely and effectively with the possibility of future reversibility. The hysteroscope will play an important role in new reproductive technologies, particularly those related to the gamete intrafallopian transfer via the uterine side and perhaps also for direct embryo transfers under visual control. The future of hysteroscopy thus is promising. The present diagnostic and therapeutic applications will not only become a standard of treatment but will expand as gynecologists will gain proficiency and confidence in this endoscopic method.

[Treatment of peritonitis in abdominal injuries].

According to the author's data, peritonitis occurred in 250 (20.8%) out of 1200 cases of abdominal injuries, 69 of these 250 patients died (27.6%). The main means combating this complication was an early surgical intervention. A complex of postoperative therapeutic procedures, aimed at the prophylaxis and treatment of peritonitis in these patients, is described.

The effect of mercury derivatives of fluorescencein on allotransplant kidney in experiment.

Mercurascan (MSC), a mercury derivative of fluorescein, was studied as to its effect on the survival of allogeneic kidney grafts in dogs. A single perfusion of the donor's kidney with saline solution with MSC added in a ratio of 1 mg/100 ml was found to have significantly extended the graft survival time from 10.8 days (SE +/- 0.6) to 15.4 days (SE +/- 1.6). Graft survival time extension proved to be even more significant after a single dose of MSC given to the donor (0.5 mg/kg b.w.) and repeated administration of an equal MSC dose to the recipient twice weekly. Listed are detailed morphological changes in tissue specimens from the kidney, lymph nodes, spleen, and many other organs of a dog surviving for 42 days. A very moderate rejection lesion with merely tiny lymphocytic infiltrates was proved in the kidney. Lymph node structure was almost entirely obliterated with lymphoid tissue extinction. There was loss of white pulp in the spleen. The absence of morphological changes in the other organs suggested good tolerance of the preparation. More studies are called for to elucidate the complex MSC intervention in the process of rejection.

The APSAC interventional mortality study (AIMS) trial: mortality data.

The anistreplase (anisoylated plasminogen streptokinase activator complex or APSAC) intervention mortality study was designed as a double-blind, placebo-controlled study to test the effectiveness of anistreplase, 30 U administered intravenously within the first 6 hours of acute myocardial infarction. The primary endpoint of the study was mortality of all causes at 30 days and 1 year. Within 30 days, there were 77 deaths with placebo (17.8%) and 40 deaths (6.5%) with anistreplase, an odds reduction of 50.5% (p = 0.0006). By the end of one year, there had been a total of 113 deaths (17.8%) with placebo and 69 deaths (11.1%) with anistreplase, an odds reduction of 42.7% (p = 0.0007).

Combined radiologic and retrograde endoscopic and biliary interventions.

Methods of treating complex biliary duct problems by a team composed of an endoscopist and interventional radiologist are described. These procedures are of two types: Those in which all manipulations are performed through the endoscope and those in which an antegrade transhepatic and a retrograde endoscopic approach are combined.

The beta-adrenergic receptor-adenylate cyclase complex as a target for therapeutic intervention in heart failure.

In the human heart the beta-adrenergic pathways are the primary means of increasing cardiac performance in response to acute or chronic stress. Control of beta pathway function is achieved by changes in the receptors themselves, and to a lesser degree by adjustments in the inhibitory G protein (Gi). In heart failure myocardial beta-receptor function is substantially reduced, but the beta-receptor pathways are so powerful that they remain capable of supporting inotropic function. Certain therapeutic interventions that improve exercise performance in heart failure can partially restore beta-receptor pathway function to normal; these interventions include beta-blocker therapy and treatment with angiotensin converting enzyme inhibitors. Other types of therapy, such as chronic administration of beta-adrenergic agonists, may produce undesirable effects by increasing beta-receptor subsensitivity; however, the effects of beta-agonists on beta-receptor function are somewhat unpredictable and certain beta-agonists do not appear to produce much desensitization. Finally, the failing human heart is in effect partially denervated due to depletion of neuronal norepinephrine, and consequently in advanced heart failure beta-agonists that possess an indirect component of action will be less effective than exclusively direct-acting agents. These observations indicate that the baseline status and the intervention-associated behaviour of the human myocardial beta-adrenergic receptor systems need to be considered in developing therapeutic strategies in congestive heart failure.

Regulation of collagenase. Therapeutic considerations.

Why the cornea ulcerates, in the sense of what goes awry, may be related to the trapping of wound healing in a phase of proteolytic debridement related to a persistent epithelial defect. The initial avascularity of the cornea makes it particularly vulnerable to proteolytic damage. Studies on the biochemistry and cell biology of corneal ulceration have indicated that sequential interactions occur which result in the generation of collagenase activity and the development of ulceration. It is likely that the interactions are susceptible to intervention; and it is thought that eventual, successful treatment of corneal ulceration will require a complex therapy, with interventions at multiple sites of regulation.

[Relapse symptom complex in rectal cancer after radical surgical interventions].

The analysis of 78 questionnaires of patients with recurrence of rectal cancer was performed which revealed this complication of surgery to occur in 60% of cases within a year after operation. Recurrences of the rectum cancer show a characteristic complex of symptoms with a certain structure of painful sensations as a central criterion.

Vector population responses to control interventions.

In 1981, Kenyan authorities attempted eradication of tsetse (Glossina pallidipes) from the Lambwe valley, by sequential aerial spraying of endosulfan. Fly populations were reduced by over 99.9% in the main habitats, but recovered to their original levels within one year. In 1986, an Argentine research team attempted local elimination of domestic Triatominae (Triatoma infestans) in an area of Santiago del Estero. House infestation rates were reduced to an apparent zero, but recovered to pre-control levels in two years. In Sri Lanka, a combination of mosquito control with active case detection and treatment reduced malaria incidence to just 17 cases in 1964. Interruption of the programme then saw case incidence return to over 500,000 by 1969. These three examples-from African trypanosomiasis, South American Chagas disease and malaria-all illustrate the same process. Vector populations, infestation rates, and rates of disease transmission, can be reduced. The real problem is not in achieving the initial reduction, but in subsequently either driving the disease to extinction or maintaining it below acceptable levels. And this problem takes us beyond the simple analysis of interventions, into the complex realms of population behaviour set in its political, social and economic context. It seems that we have been too rarely concerned to plan and implement the long term surveillance and selective interventions that are required to translate initial gains into real success. In biological terms, we tend to ignore the complexity and robustness of vector populations and disease transmission cycles, especially their varied capacity to recover from interference. Moreover, in socio-political terms, a reduced problem-even one representing potential for future catastrophe-tends to claim less priority than present problems, even though premature redeployment of resources may abnegate gains already achieved. The problem is strongly compounded by methods of economic analysis where the benefits of avoiding future problems are strongly discounted in favour of short-term temporary gains. This paper seeks to open discussion on these long-term planning issues.

Management of ventricular arrhythmias.

Left ventricular dysfunction and complex VPCs are independent risk factors for subsequent cardiac death in patients with ischemic or nonischemic heart disease. The use of antiarrhythmic drugs during acute myocardial infarction is discussed. Patients with complex VPCs associated with heart disease should be treated with antiarrhythmic drugs. Drug efficacy should be evaluated by a 24-hour ambulatory ECG recording and by a treadmill exercise stress test. Blood drug levels should be measured at appropriate times. Maintenance doses of the various antiarrhythmic drugs are listed. Electrophysiologic testing with induction of ventricular tachycardia by extrastimulation may predict the clinical efficacy of the antiarrhythmic drug or combination of drugs needed for the long-term treatment of ventricular tachyarrhythmias. Electrophysiologic testing must be used for selecting antiarrhythmic drugs in patients who have experienced sustained ventricular tachycardia or ventricular fibrillation but who are free of VPCs during ambulatory ECG monitoring and exercise stress testing. If patients have life-threatening ventricular tachycardia or fibrillation resistant to antiarrhythmic drugs, surgical intervention is indicated. Complex VPCs in asymptomatic patients without heart disease should not be treated with antiarrhythmic drugs.
