Personality traits in scheuermann's disease - a controlled study

SOMHEGYI Annamária, JÁNOSFI Zsuzsa, BALÁZS István, RATKÓ István

High muscle tone in various muscle groups is typical in Scheuermann's disease, and secondary fibromyalgia often occurs in young adults after this condition. There are clinical observations of emotional-psychological disturbances in adolescents with Scheuermann's osteochondritis. For these reasons it was of interest to determine whether any particular personality traits were manifested in adolescents with Scheuermann's disease, that - in addition to the spinal pathology – would contribute to the high muscle tone. Using four personality diagnostics tests (Brengelmann's questionnaire, Taylor's anxiety scale, Neurosis Scale, Lüscher's 8-colour test) we investigated the emotional life of 52 adolescents with Scheuermann's osteochondritis and that of 52 matched healthy controls. Test results of the two groups were statistically evaluated using chi square tests, with a significance limit of p < 0.05. The most striking difference between the two groups was that the patient's volitional and diffuse psychic tensions were increased (c = 1.00 and p < 0.0005) and, at the same time, were accompanied by a significant deficiency of the means to discharge them ( c = 1.00 and p < 0.0005). The results indicate that Scheuermann-patients do not answer to the stresses of everyday life in the usual way but by an increase in muscle tone. Their muscles act as their stress organ. This - in addition to the spinal pathology - may contribute to the tightness of their muscles and might be considered as a possible predisposing factor to later secondary fibromyalgia. Therapy should seek to interrupt this vicious circle by complementing regular exercise with relaxation techniques.

Management proposal for the treatment of acute odontoid fractures

RÓBERT Veres, GILES Hamilton Vince

Optimum management of the acute odontoid fracture has always been extensively discussed. Nowadays, with the availability of new operative techniques such as anterior odontoid screw fixation and the posterior C1-C2 transarticular screw fixation the management policy has to be reevaluated. The authors review 115 cases of type II and type III acute odontoid fractures admitted to the National Institute of Traumatology in Budapest between 1980 and 1990. For study purposes a modified Anderson-D'Alonzo classification was introduced allowing a more detailed description of the fracture components and thus enabling to find more clear guidelines for treatment planning. The patients were treated with: a. various types of non-Halo external fixation in 27 cases; b. Halo immobilization in 13 cases; c. various surgical procedures resulting in a loss of atlantoaxial joint function in 22 cases; d. anterior odontoid screw fixation in 53 cases. Modern therapy should be focused on preserving the function of the atlanto-axial joint whenever possible. This can be sufficiently achieved using anterior odontoid screw fixation. However, the main determining factor in the choice of the appropriate treatment - providing the ligaments are intact - is the direction and course of the fracture line. If the fracture line runs horizontal or oblique posterior anterior screw fixation is the most favourable treatment. On the other hand if the fracture line runs oblique anterior Halo immobilization or C1-C2 posterior fixation is the method of choice.

[CT guided stereotactic radiosurgical treatment of cerebral metastatic tumors]

FEDORCSÁK Imre, HORVÁTH Ákos, KONTRA Gábor, SLOWIK Felicia, OSZTIE Éva

[Radiosurgery has in recent years been used with promising results in the treatment of cerebral metastases. Between July 1991 and January 1993 we treated 23 patients harbouring brain metastases (39 lesions) with our Linear accelerator based radiosurgery system. The median tumor size was 1.9 cm (1.0-3.0 cm) and the median delivered dose was 18.7 Gy (13–25Gy). Follow up CT scans at 4 months showed a complete remission or greater than 50% tumor volume reduction in 19 patients (82%). No change was noted in 2 patients (9%), and after a transitory decrease an increase in tumor size was seen in 2 patients (9%). Follow up time was minimum 6 month (or till death), and maximum 26 months. We have lost 13 patients during the study, and the cause of death was neurologic in only 2 cases. Our experience supports the cumulating evidence that radiosurgery is an effective treatment for metastatic brain tumors, is well tolerated by the patients, and can be applied also in cases where open surgery can not be performed.]

[Real time and color doppler sonographic investigation in cases of fetal hydrocephaly and cerebral hemorrhage]

JAKOBOVITS Ákos, JÖRN Hendrik

[In three hydrocephalic and one fetus with intra- and periventricular hemorrhage real time imaging was used to identify cerebral changes. Color flow imaging was used to identify the fetal middle cerebral and umbilical artery for subsequent pulsed Doppler sonographic studies. Cerebral blood flow patterns of hydrocephalik fetuses seem to differ individually from case to case presenting normal, increased and decreased velocity waveform indices. The resistance index and pulsatility index of the middle cerebral artery in case of cerebral hemorrhage increased with advancing worsening of the fetal state of health. Loss of diastolic cerebral or umbilical flow followed by retrograde flow during diastole antenatally could be a bad sign prognostically. ]

[Hungarian professional periodicals started quite late in European context. Their publish­ing, editing and editorial philosophy were equally influenced by specific historical and political situations. Certain breaking points of history resulted in termina­tion of professional journals (War of In­de­pendence 1848-1849, First and Se­cond World Wars), however there were pe­riods, which instigated the progress of sciences and founding of new scientific journals. Both trends were apparent in years after the fall of former Hungarian regime in 1990. The structure of book and journal publishing has changed substantially, some publishers fell “victim” others started successfully as well. The latters include the then-established publishing house Literatura Medica and its own scientific journal, Lege Artis Me­di­cinae (according to its subtitle: New Hun­garian Medical Herald) issued first in 1990. Its appearance enhanced significantly the medical press market. Its scientific publications compete with articles of the well-established domestic medical journals however its philosophy set brand-new trends on the market. Concerning the medical community, it takes on its problems and provides a forum for them. These problems are emerging questions in health care, economy and prevention, in close interrelation with system of public health institutions, infrastructure and situation of those providing individual health services. In all of them, Lege Artis Medicinae follows consequently the ideas of traditional social medicine.]

[No luck for the Hungarian Medical Chamber's Bureau draft law to discuss the draft law with MPs. About six months ago, the Social Affairs Committee wanted to put the draft on its agenda for debate, but was thwarted by the question of form, which was only apparently a question of form, but in fact of substance: if it is a draft law, who submitted it to the parliamentary committee. A professional body is not entitled to do that. On this basis, the Members did not wish to discuss it at the time - at least now, and let us be precise here! - the draft chamber bill. Since then, the Presidency of the Chamber has revised the drafting in a public debate, has thoroughly liberalised it and would have liked to present it to the Members of Parliament who are doctors, and discuss it, now wisely calling it a working document. Such a meeting is not a statutory forum, has no agenda, and is not intended to be a lobbying exercise in the good sense.]

[We heard in forums]

[The 1993 Social Security Budget Act and, as part of it, a series of provisions setting out the way forward for the reform of primary care and initiating the reform of specialised care. However, the government and ministerial decrees implementing the provisions and setting out the technical details are not yet known. Health professionals are still full of uncertainty and doubt. The time has come once again for forums in which the leaders of health policy - the authors of the laws and the drafters of the expected regulations - give presentations explaining and justifying what has already happened and informing about expected developments. At the same time, of course, they "sound out public opinion". The huge interest that greeted the speakers at the first forum of the "season" of the complementary event of the International Medical Technology Exhibition in the Theoretical Block of the SOTE Oradea Square, was not so much a sign of the organisers' success as of the doctors' lack of information, their uncertainty and their hunger for information.]
