[From Tadini to Svjatoslav N. Fedorov. Difficulties of ophthalmologic surgery].

In 1765/66, the oculist Tadini showed to Giacomo Casanova artificial lenses, which he planned to implant into human eyes after removing the cataract by extraction. About 1795, the oculist Casaamata tried to put into effect Tadini's idea. It was not before 1949, however, that H. Ridley implanted the first artificial lens, when he had found out that acrylic glass could serve the purpose. In 1960, Svyatoslav N. Fedorov implanted the first hand-made artificial lens in the USSR. His successful operation was discredited to be non-physiological and antipavlovistic. He had to overcome many difficulties, but became important by promoting modern microsurgery of the eye in the USSR. Since 1974, he introduced his version of radial keratotomy to correct myopia surgically. Today Fedorov is managing a technical-scientific complex in Moscow with twelve branches throughout the Soviet Union and with 5500 employees. In this complex, his radial keratotomy should be used as standard treatment of visual defects, in spite of its controversial quality. For that reason Fedorov fails to export his special method, which might be an experimental stage towards new refractive therapies.

[The oculist Joseph Hillmer in Berlin 1748-1768].

We know quite a lot about the life of the oculist Joseph Hillmer of Vienna between 1746-1775, especially from newspapers of that time. In 1748, Frederic II of Prussia appointed him to a professorship at the Berlin Collegium Medico-Chirurgicum, where his duties were to lecture on ophthalmiatrics twice a week. In 1751 he travelled via Livonia and Estonia to St. Petersburg. After 4 months he was denounced as a charlatan. The First Physician at the court of the Tsarina Elisabeth, Herman Kaau Boerhaave, acting in his capacity as director of the Medical Chancelry at Petersburg (the Russian medical supervising board), had Hillmer expelled from the Russian empire. He also collected all the documents relating to the affair and published them as a book at his expense. The Tsarina suppressed the book, which contained case reports on 125 of Hillmer's patients. There is much to indicate that she was motivated by tactical diplomacy, since the oculist had been involved in such matters by the Prussian king during the preliminaries to the Third Silestan War (1756-1763). Hillmer never held a single lecture during his period of tenure as a professor in Berlin, and there is very little evidence of his ever having practised there. Nonetheless, he had owned a large house near the Berlin castle which he also extended to allow its use for public concerts and festivities. During the summer he let the house while traveling extensively throughout Europe and attending patients in many different places, so that he lived in the house only in winter. After his return from Russia he sold his horses and, later, also his coach.(ABSTRACT TRUNCATED AT 250 WORDS)

[Ophthalmology in the 18th century: the "oculist seculum" in Berlin].

At least 15 oculists were known in Berlin in the eighteenth century, beginning with Johann Andreas Eisenbarth, who visited the Prussian royal residence five times. From 1725 on, four oculists resided in Berlin for up to 33 years. Since 1740, lectures on ophthalmology had been given here as part of the surgery curriculum at Berlin Collegium Medico-Chirurgicum by Simon Pallas and, as of 1769, by Joachim Friedrich Henckel. Both of them taught the traditional method of couching the cataracts, which they also treated themselves. Christian Ludwig Mursinna first used the cataract-extraction method by Daviel at the Collegium Medico-Chirurgicum when he was appointed Professor of Surgery in 1787. The oculists who visited Berlin had demonstrated this new surgical method at least 15 years earlier. The very first cataract extraction in Berlin seems to have been done by the French military surgeon Taverne in 1755. There were two charlatans among the oculists: John Taylor, who was expelled from Berlin and Prussia in 1750, because Frederik II had found him to be an English spy. The same king appointed the other charlatan, Joseph Hillmer from Vienna, a Professor of Ophthalmiatrics at the Collegium Medico-Chirurgicum, in 1748. Hillmer's charlatanism was proven by the Medical Chancellery at Petersburg when he visited Russia in 1751. The Director of the Russian Medical Supervising Board, Herman Kaau Boerhaave, documented this affair in a book, which is the first printed source of Russian medical language. Hillmer was expelled from Russia. He had never given lectures in ophthalmiatrics in Berlin.(ABSTRACT TRUNCATED AT 250 WORDS)

[Stress fractures of the navicular bone. Roentgen diagnosis of a rare fracture].

Stress fracture of the tarsal navicular are rare and their diagnosis is often delayed. 1982 and 1983 we found stress fractures of the os naviculare pedis in 16 patients, 8 fractures were complete and 10 incomplete. Three types of radiographic findings are sclerosis, radiolucency and radiolucency with sclerotic borders. The fractures were localized in the middle third of the tarsal navicular. Laminography is necessary to evaluate the radiographic changes and their extension.

[Fatigue fractures in top athletes. Value of and indications for skeletal scintigraphy].

The early exclusion of the presence of a stress fracture may be decisive for the success of an athlete. Scintigraphy with a bone-seeking radiopharmaceutical is suitable for the early detection of stress lesions. Of 30 athletes, fractures were demonstrated in 17 whereas in 6 they were excluded. We found most fractures in the tarsal bones such as os naviculare pedis, ossa cuneiformia and talus. The type of sport engaged in appears to be an important factor in determining the location of the fracture. Scintiphotos were taken in several views using region of interest techniques and two phase-scintigraphy. This method is considered to be useful for localization and follow-up of skeletal stress lesions as well as for differential diagnosis.

[Cisplatin as a radiosensitizer in the treatment of solid tumours--a clinical pilot study].

A variety of experimental tumour models have shown that cisplatin in combination with ionizing radiation enhances tumour regression. To evaluate the feasibility, efficacy and toxicity of a combined regimen, 25 patients with different solid tumours were treated with cisplatin and photon irradiation. A local tumour control was achieved in 22 cases. Thirteen patients with squamous cell carcinoma of the lung (T1-3, N1-2, M0) received cisplatin (20 mg/m2 per day) on 5 consecutive days with NaCl hyperhydratation (0,9% NaCl, 2400 ml/24 hours as continuous infusion) in the first and last week of radiotherapy (5 X 2 Gy/week, 56 Gy target volume dose). 12 of 13 patients have shown local tumour control. Increased clinically evident side effects were not observed. From the underlying data the conclusion is drawn that the experimental results are reproducable under clinical conditions and that improved local tumour response rates can be achieved.

Tomographic localization of motion axes.

Localization of motion axes within joints and junctures in living humans has been carried out by means of roentgen stereophotogrammetry. Another technique is presented here, in which the localization of the axis is carried out by means of tomography. The field of application for this technique has been examined in a series of phantom experiments. It may be employed in certain situations where roentgen stereophotogrammetry is not useful. No other equipment is needed than a pluridirectional tomograph and conventional dark-room facilities.

Effect of intra-arterial CO2 insuffflation on occlusive arterial disease in the lower leg.

Twenty patients with a mean age of 79 years were followed over a period of 6 months after intra-arterial insufflation of CO2 in the lower extremity. All patients had severe peripheral occlusive arterial disease caused by atherosclerosis and were scheduled for amputation. A significant increase of the distal perfusion pressure was obtained in the majority of the cases resulting in pain relief and healing of ulcers and gangrenes.

Value of a follow-up study of recurrent carcinoma of the colon and rectum.

The results of our programmed follow-up study of patients with carcinoma of the colon and rectum have been disappointing. This is true also for those patients who have undergone resection with the intention of cure. This is mainly because of the discouraging results of our treatment of recurrent lesions. Chemotherapy or roentgen radiation has not regularly been used. The mean survival time has probably been prolonged in some single instances. Only three out of 36 are still alive. Oour negative results show that a follow-up study of this magnitude has been too extensive when the poor outcome is considered. We believe that a follow-up study of patients who have been operated upon for carcinoma of the colon and rectum is necessary but in a simpler form than we have done.
