Twenty-two cases with carcinomas of the nasal cavity, sinuses, buccal and orbital regions treated in the Radiotherapy Clinic of University Central Hospital in Turku, are presented. The dose delivered to the eye was 1400 to 6300 rd. The most usual radiation complication was keratitis which appeared in 15 cases, cataract was diagnosed in seven cases, corneal ulcer in three, iritis in two, retinopathia in two, and glaucoma in three cases. Most of the complications could be relieved or cured with appropriate therapy. In only one case the eye was to be enucleated because of severe glaucoma and corneal ulceration. As the prognosis of malignant tumours in this area usually is bad, irradiation to the eye on the affected side is to be taken as a calculated risk to achieve a more effective cancer control.

A congenital teratoma of the orbit is described. Histologically, the tissues forming the tumor appeared derived from the three germinal layers and showed an advanced degree of differentiation. An exenteration was performed because of suspicion of malignant tumor in the orbit and because of the severe keratitis with impending perforation which ensued the lagophthalmos.

Persistent trigeminal neuralgia, herpes zoster neuralgia of the first division of the trigeminal nerve and pain caused by cancer situated in the head and neck pose frustrating problems for patients and physicians. Tractotomy and/or partial vertical nucleotomy of the subnucleus caudalis nervi trigemini offers a logical approach to the treatment of such pain, since these structures contain fibres of the Vth nerve, as well as the somatosensory fibres of the VIIth, IXth and Xth nerve. Tactile and some thermal sensitivity of the face is preserved and anaesthesia dolorosa and keratitis neuroparalytica is avoided. Over the past 30 years 370 patients with therapy-refractory trigeminal pain, pain due to cancer of the head and neck and herpes zoster trigeminal pain were treated by means of tractotomy (personal series of V. Grunert), including 30 patients who underwent partial vertical nucleotomy. The mean age of the patients was 68 years (range 54-84 years). The mortality in this series was 0.9% (4 patients; one operative mortality due to air embolism, one postoperative cardiac failure following myocardial infarction and two intracerebral haematomas). 60% of the patients with persistent trigeminal neuralgia were pain-free and 28% improved, whereas 12% were unchanged or suffered from recurrent pain. Of the patients with cancer who complained of pain derived from the Vth, VIIth, IXth and Xth nerve, 40% demonstrated marked pain relief and 60% showed no improvement. Tractotomy and partial vertical nucleotomy offer a valuable method in experienced hands for relieving pain where other methods have failed.

Pseudomonas aeruginosa is an important cause of infection in immunosuppressed patients, particularly those with cancer. However, it is being recognized with greater frequency in patients who appear to be immunocompetent. Changes in modern lifestyles have led to the appearance of some new manifestations of pseudomonas infection including corneal ulceration and keratitis associated with contact lenses, and hot-tub- or whirlpool-associated folliculitis. These represent additional hazards to patients with cancer. Many studies, both in animals and humans, have contributed to our knowledge of the pathogenesis, immunology, treatment, and prevention of pseudomonas infections. Although the aminoglycosides represented a significant step forward in the treatment of these infections, of greater importance was the discovery of the antipseudomonal penicillins. These antibiotics are more effective than the aminoglycosides in neutropenic patients, who are especially susceptible to pseudomonal infections. The older antipseudomonal penicillins (carbenicillin, tircarcillin) have largely been replaced by newer ones (mezlocillin, azlocillin, pipercillin) which are more potent in vitro against P. aeruginosa. Although the accepted therapeutic practice has been to utilize a penicillin in combination with an aminoglycoside, the introduction of newer beta lactam agents and fluoroquinolones with antipseudomonal properties offers the possibility of other approaches to combination therapy. These include the combination of a penicillin or a cephalosporin or the combination of a quinolone with an aminoglycoside or a betalactam antibiotic. However, the development of newer antimicrobial agents is not likely to be a lasting solution to the problem of pseudomonas infections. Since pseudomonas infection often progresses rapidly, optimal results will always depend upon the prompt initiation of appropriate therapy in febrile patients, particularly those who are at high risk. The use of granulocyte transfusions has proved to be of limited benefit. Early data with the use of monoclonal antibodies is promising, and the results of large-scale trials are eagerly awaited. It is hoped that continuing investigation of pseudomonas vaccines will lead to the discovery of effective prophylaxis for highly susceptible patients. It is also hoped that with the availability of GM-CSF it will become possible to reduce the period of risk for serious infections. Finally, a reduction in the frequency of microbiologically proven P. aeruginosa infections in cancer patients should not lead to the assumption that these organisms do not constitute a problem in such patients anymore. The use of prophylactic antibiotics and prompt empiric antibiotic coverage for therapy has resulted in this decline. Cultures are therefore unlikely to be positive with the same frequency as they were before antimicrobial prophylaxis and empiric antibiotic therapy became standard practice.(ABSTRACT TRUNCATED AT 400 WORDS)

Extensive cutaneous mycoses have been described in patients with the keratitis, ichthyosis, and deafness (KID) syndrome. We present a case occurring in a 48-year-old woman where improvement in the ichthyosiform dermatosis, stabilization of her ocular disease, and apparent partial prevention of further cutaneous malignancies occurred in association with ketoconazole therapy.

An ocular toxic reaction presenting as conjunctivitis or keratitis develops in a significant number of patients who are treated with high-dose cytosine arabinoside (ara-C). Although eye drops containing glucocorticoid reportedly decrease the incidence, they do not totally eliminate this side effect. In comparing this technique with artificial tears, both were found to be equally effective. The primary mechanism by which eye drops decrease ocular toxic reactions associated with high-dose ara-C is presumably due to dilution of intraocular concentrations of ara-C.

Interferons (IFN) are potent antiviral, cytostatic-cytotoxic and immunomodulatory agents. Although gene technology has made available an unlimited supply of all different kinds and types of IFN, their basic modes of action have not been clarified up to now. The therapeutic effects proven differ gradually between the individual disease entities. They comprise prophylaxis, prevention of recurrences and direct therapeutic effect, either of reducing the actual disease symptoms, or of inducing a complete recovery. For the following viral diseases a positive therapeutic effect has been shown: infections by herpes-viruses (herpes simplex keratitis , herpes zoster, herpes simplex), cytomegalovirus infections, chronic-hepatitis B virus infection, acute respiratory virus infections by rhino-, corona- and influenza viruses. Especially for the group of virus-associated tumors and papillomas, IFN is considered to be therapeutically effective. IFN has been accepted to be the first line treatment for laryngeal papillomatosis. In condylomata acuminata too, IFN is a potent therapeutic agent. Moreover, IFN represents the most effective therapeutic modality for Kaposi's sarcoma in patient with AIDS. Hairy cell leukemia, malignant lymphoma, multiple myeloma, melanoma and hypernephroma are the malignancies, for which a therapeutic effect of IFN could be proven. Furthermore, IFN is considered to be the therapy of first choice for hairy cell leukemias. Although there are some signs, that IFN could be a potent agent for adjuvant therapy, this question can not be answered - not even on principle - because of lacking sufficient data so far. Up to date, the therapeutic efficacy of IFN seems to be established only for hairy cell leukemia, laryngeal papillomatosis, Kaposi's sarcoma in patients with AIDS and partly for condylomata acuminata. For all other indications, first of all, sufficient phase-II-study data will have to be evaluated, before prospectively controlled studies, comparing the IFN treatment results with placebo and standard therapy results, can be initiated for the individual disease entities. Then, it will be possible to assess the therapeutic efficacy of IFN. Already now, IFN represent a valuable enrichment of the therapeutic modalities for malignancies and viral diseases.

Ida Mann's wartime accomplishments were most remarkable. Besides her Harley Street practice and her senior appointment at Moorfields (The Royal London Ophthalmic Hospital), she prevented its closure to ophthalmic patients and chaired the Hospital Management Committee; she investigated the pathology of mustard gas keratitis and formed a Chemical Defence Research Team to study ocular effects of warfare chemicals; she was appointed Margaret Ogilvie Reader in Ophthalmology and senior surgeon to the Oxford Eye Hospital; she established the Nuffield Research Laboratory and was awarded a personal professorship, the first in ophthalmology in Britain, the first professorship given to a woman and the only one in ophthalmology by the University of Oxford. Late in the war she married a cancer research pathologist in whose laboratory she cultured a malignant tumour of the lens. Furthermore, she produced a vast number of outstanding research papers, most notably the authoritative monograph on chemical injury to the anterior segment of the eye.

The therapy of face and neck pain has often been elusive. We attempted to improve the condition of these patients and tried to influence 1. pain of trigeminal neuralgia, where other forms of therapy had failed, 2. pain due to tumours in the distribution of the Vth, IXth and Xth nerve, when all other methods had proved to be unsuccessful, 3. pain due to a traumatic lesion of the Vth nerve after severe injury of the face and 4. pain in the first division of the Vth nerve after herpes zoster infection, when other forms of therapy had failed. After tractotomy the subnucleus caudalis n.V. is partially destroyed. Aim of the partial vertical nucleotomy is the interruption between the first and second neuron of the Vth nerve conveying pain and thermal sensibility, but also of the IXth and Xth nerve, which end in the subnucleus caudalis n.V. as well. Tactile and some thermal sensibility in the face is so retained, and anesthesia dolorosa or keratitis neuroparalytica avoided. Medially of and vertically to the tractotomy a 4-6 mm long incision both cranially and caudally of the tractotomy was made. For the first division of the Vth nerve the nucleotomy is performed on the lateral end of the tractotomy incision. In the patients with cancer of the face and neck a rhizotomy C 1/2 was added. 7 of the 12 patients with trigeminal neuralgia and 3 of the 6 patients with tumors of the face and neck were pain-free. The rest also showed a marked improvement.(ABSTRACT TRUNCATED AT 250 WORDS)

Patients with advanced lymphoma who relapse from intensive first-line combination chemotherapy generally have a very poor prognosis. The use of investigational drugs which lack cross-resistance to agents commonly used for initial therapy represents an important approach to the management of such patients. Based upon our prior experience, we developed a protocol which employed a combination of three new agents. Mitoguazone (600 mg/m2) was administered on Days 1 and 10; etoposide (100-125 mg/m2) was administered on Days 2, 3, and 4; and gallium nitrate (300 mg/m2/day) was administered as a continuous iv infusion over 24 hours on Days 1-7. Treatment cycles were repeated every 3-4 weeks pending tolerance to toxic reactions. Forty-two patients are evaluable for response (35 with non-Hodgkin's lymphoma and seven with Hodgkin's disease). All patients had received extensive prior treatment (median of two previous chemotherapy regimens). Less than one-half of patients had achieved complete remission (CR) with previous therapy. Twenty-two patients (52%) showed major antitumor responses (five CR, 17 partial). All patients who achieved CR had diffuse large cell lymphoma. Two patients in CR relapsed in the CNS. The median duration of response for patients who achieved partial response was 4 months (range, 1-11+). Major toxic reactions included myelosuppression, optic neuritis, mucositis, and corneal keratitis or conjunctivitis. This combination of experimental agents has major therapeutic activity in patients with advanced, resistant lymphoma. Optimal application of these drugs may be obtained by use as one arm of an intensive program of alternating non-cross-resistant regimens.
