A 14-year-old boy with ataxia-telangiectasis died of pneumonia, stomach cancer and its diffuse metastasis. The onset of walding gait was noticed from 3 years of age. Immune globulin including IgA was normal or slightly increased. Main autopsy findings were: old cancerous ulcer of 1.4 X 2.3 cm at the lesser curvature, and diffuse cancer infiltration over ulcer surface to serous membrane. The tumor was diagnosed histologically as adenocarcinoma tabulare mucocellulare.

From January, 1975 through June, 1986, 426 patients with mammary carcinomas were submitted to primary, breast-preserving therapy at the Gynecological Hospital of the University of Heidelberg. 212 women with a minimum observation time of twelve months fulfilled the criteria of a "typical" treatment: tumor size up to 3 cm, segment/quadrant resection and axillary lymphonodectomy with at least eight lymph nodes removed, radiotherapy of the residual breast with greater than or equal to 45 Gy, in case of histological lymph node manifestation adjuvant hormonal and/or chemotherapy. The average observation time was 38 months, the medium age 48 years. Patients with histological lymph node manifestations were compared with a matched control group of women treated treated by modified radical therapy. According to the error estimation of Kaplan and Meier (1958), no differences were found for local recurrence rate, disease-free survival, and overall survival. Patients treated by organ-preserving therapy with adjuvant chemotherapy were opposed to a matched control group of women treated only by surgical/radiological, organ-preserving therapy. In patients with chemotherapy, the incidence of cutaneous erythema (29% versus 24%), telangiectasia (34% versus 24%), hyperpigmentation (41% versus 34%) showed an upward tendency, but was not significantly increased. There was no difference in the incidence of clinically palpable fibroses (37% versus 42%) and fibroses shown by mammography (54% versus 51%). The frequency of pneumonitis/fibrosis of the retromammary lung area (22% versus 10%) after chemotherapy was two times higher than in the matched control group not treated by chemotherapy.

In 1978-1980, inclusive, all breast cancer patients referred for postmastectomy irradiation were treated by 2 fractions per week (73 patients) but due to a high incidence of late complications this fractionation schedule was changed from early 1981 to 5 fractions per week (66 patients) with dose adjustment according to the nominal standard dose (NSD) concept. The dose aim in both regimens was 1345 ret minimum target dose. This allowed a comparison of acute and late complications in the two patient groups treated to the same NSD value, but with different fractionation. The patients have been analysed with respect to acute and late reaction in the skin, subcutaneous tissue, lung and bone, as well as related complications, such as arm oedema and impairment of shoulder movement. Except for the acute skin reactions, all other endpoints could not be adequately predicted by the NSD formula. Thus, telangiectasia greater than or equal to grade 1 and skin fibrosis greater than or equal to grade 2 were found to be 75% and 67% in patients treated with the 2-fraction scheme versus 39% and 5% in patients treated with the 5-fraction scheme. In the 2-fraction regimen, a higher frequency of impairment of shoulder movement and arm oedema was found compared to the 5-fraction regimen, 38% versus 11% and 44% versus 33%, respectively. The acute lung reaction as well as late lung reaction were significantly more pronounced in the 2-fraction regimen than in the 5-fraction regimen (pneumonitis greater than or equal to grade 2, 43% versus 23%, and lung fibrosis greater than or equal to grade 2, 32% versus 17%, in the photon fields, respectively). Further, radiation-induced osteonecrosis in the ribs was significantly more frequent in patients treated with large dose per fraction (19% versus 2%). The data clearly demonstrates the danger by using the NSD formula in equation of two different fractionation schedules. This formula as well as other mathematical models can only be used with caution within the limitations defined by the underlying clinical and experimental data on which they have been derived.

Radiation therapy is the elective treatment of inoperable non small cell lung cancer, but is potentially curative only for a few of them: failures result from distant metastases and/or from progressive local disease. During the last years, following the progress in chemotherapy, combining radiation and drugs is becoming a more common approach. Nevertheless, one of the main concerns remains the potential interference between both modalities leading to an increased toxicity, which may outweigh all potential benefit. Several organs can be a target for acute or late toxicity: lung (pneumonitis and fibrosis), esophagus (acute esophagitis, stenosis), heart (pericarditis, impaired ventricular functions, heart failure, coronary stenosis), spinal cord (transient myelopathy, radiation myelitis), skin (moist desquamation, fibrosis, telangiectasia). The current published trials combining drug and radiation appear to be a rather safe approach especially when avoiding concomitant treatment. However, several points remain unsolved: the optimal combination scheme, the real risk of late damage observation including the second cancer occurrence risk. This risk is uneasy to evaluate due to the long latency period. The way of describing the late damage is crucial, seeking for a more precise system of evaluating, recording and reporting late effects, taking into account objective damage as well as the patient's symptoms. Therefore, combining drug and radiation should preferentially be performed within prospective studies, with precise evaluation procedures.

Causes of hemoptysis in children have not been well documented in the paediatric otolaryngology literature. The aim of this retrospective review is to determine the commonest causes of hemoptysis in the paediatric age group presenting to an otolaryngologist. We reviewed the charts of patients presenting to an otolaryngologist at The Hospital for Sick Children, Toronto, Ontario, over a 10-year period. A total of 37 inpatients beyond the neonatal period were referred for further assessment of hemoptysis. Thirty-two patients (86.5%) underwent bronchoscopy to determine the cause, the hemoptysis resolving spontaneously in the remaining five patients without a diagnosis. Four patients who had a bronchoscopy also had no identifiable pathology. Tracheobronchitis was the commonest diagnosis (19%), followed by tracheotomy-related problems (15.5%) Other causes included bronchiectasis, aspiration of blood, pulmonary hemorrhage, foreign-body aspiration, cystic fibrosis, A-V malformation, tracheobronchial hemangioma, hereditary telangiectasia, laceration of a vocal cord, and pneumonia. Otolaryngologists need to be aware of the etiology of hemoptysis in children. The commonest causes are infection and trauma, and not vascular anomalies or neoplasms as often perceived.

Dermatologic lesions are often associated with pulmonary disorders and vice versa. Diseases with pulmonary and cutaneous manifestations can be divided into four major categories: (a) congenital and developmental disorders with cutaneous-pulmonary manifestations (Ehlers-Danlos syndrome, generalized elastolysis, yellow nail syndrome, neurofibromatosis, hereditary hemorrhagic telangiectasia); (b) primary dermal diseases with associated pulmonary manifestations (septic vasculitis, malignant melanoma, Kaposi sarcoma); (c) primary pulmonary diseases with associated cutaneous manifestations (tuberculosis, Pseudomonas pneumonia, mycoplasmal pneumonia, adenocarcinoma, metastasis); and (d) cutaneous-pulmonary conditions (multisystem disorders) (progressive systemic sclerosis, systemic lupus erythematosus, Wegener granulomatosis, sarcoidosis). A series of selected cases is used to illustrate the radiologic and dermatologic features of conditions that affect both the lung and dermal tissue. Specific emphasis is placed on the dermatologic manifestations of disease. Diagnosis of a pulmonary-cutaneous disorder requires familiarity with the morphologic appearance of the cutaneous lesion.

In the UK, fundamental changes are occurring to the organization and delivery of services to breast cancer patients, prompted by the Calman/Hine initiative and by the perception that outcomes in the UK compare unfavourably with the rest of Europe and North America. Breast cancer, being a common malignancy, has often been treated by general surgeons and oncologists rather than by site-specialized multidisciplinary teams. Outcome results for many of these surgeons and oncologists may be unknown, so it becomes difficult, in any particular centre, to quantify changes that arise from the reorganization of treatment services and adherence to new guidelines without first determining baseline results. A retrospective audit of the 350 patients with primary breast cancer who received radiotherapy in Velindre NHS Trust in 1988-1989 has been performed to provide a baseline against which future results can be measured following the adoption of agreed guidelines. The endpoints for this study were: the completeness of data; actual treatment received versus current guideline recommendations; locoregional recurrence rates; and radiation related morbidity. The adherence to agreed guidelines is likely to ensure more appropriate surgery of the primary disease and will limit radiotherapy compared with 1988-1989 in that much radiation to the axilla and Internal Mammary Chain and 'booster' treatment to the primary site will be avoided in the future. The incidence of brachial plexus neuropathy was consistent with the radiation doses used and an analysis of this data suggests that the adoption of the guidelines will probably result in the complete avoidance of this complication in the future. Likewise, it is expected that the incidence of soft tissue fibrosis, telangiectasia and pneumonitis should diminish, but this and the effect of the clinical guidelines on local recurrence rates remains to be demonstrated by future comparable audits.

From January 1987 to December 1993, Stage I (T1N0M0) breast cancers were treated by quadrantectomy with axillary lymph node dissection plus radiation therapy (QUART) in 57 cases and by modified radical mastectomy (MRM) in 57 cases. The results for these two treatment groups were compared retrospectively. Booster irradiation of 10 Gy to the tumor bed was given to 1 of 5 cases with a positive resection margin. The remaining 56 cases received 50 Gy lineac X-ray to the ipsilateral breast. Systemic adjuvant therapy, tamoxifen and /or 5-FU derivatives p.o., were given to the majority of cases in both groups. There were no significant differences between the two groups with regard to the patient background; ie, age, tumor size, pathological node status, histology and estrogen receptor status. During the follow-up period of 12 to 89 months (median 55 months) in the QUART group, no local recurrence was observed and only 1 case of bone metastasis occurred. In the MRM group, recurrence occurred in 4 cases during the follow-up period of 12 to 95 months (median 52 months). These consisted of 2 cases of regional lymph node recurrence and 2 cases of lung metastases. The differences in the disease-free survival rate and the overall survival rate between the two groups were not significant. In the QUART group, mild radiation pneumonitis and mild telangiectasia in the breast skin were observed in 2 cases(3.5%) and 1 case, respectively. Mild arm edema was observed in 4 cases (7%) in each group. These results demonstrated that QUART was as effective as MRM in treating T1M0M0 breast carcinoma in Japanese women.

Ataxia telangiectasia (A-T) is a rare autosomal recessive multisystem disease. The diagnosis of A-T is based on the typical clinical picture: ataxia and telangiectasia. However, an increase in (alpha-fetoprotein (AFP) level and the identification of the A-T mutated gene (ATM) assist in an early diagnosis. Here we report two cases of A-T diagnosed in our hospital (case 1: a 7-year-old boy; case 2: an 8-year-old girl). Both of these patients had typical clinical pictures of ataxia and telangiectasia, AFP was also increased (case 1:471.2 ng/dL; case 2: 196 ng/dL). T-cell dysfunction was noted in both patients. Case 1 had IgG2 deficiency and case 2 had IgA, IgG2 and IgG3 deficiency. Case 2 developed malignant lymphoma at 9 years of age and died of pneumonia with respiratory failure at 10 years of age. Because of rhe rarity of A-T in Taiwan, we report two cases to help pediatricians make an early diagnosis of A-T if they have a patient with progressive ataxia and oculocutaneous telangiectasia.

A 25-year-old man was admitted to the Department of Neurology, Gunma University Hospital, in June 1997. He had an intellectual disability and had suffered from repeated infection since childhood. Cerebellar ataxia had developed at 19 years of age and he had been clinically diagnosed with ataxia telangiectasia (AT) comprising cerebellar ataxia and oculocutaneous telangiectasia at 24 years of age. He died from pneumonia and renal failure at 26 years of age. Neuropathological examination revealed Purkinje cell loss and atrophy of the dentate nuclei in the cerebellum, anterior horn-cell atrophy and demyelination of the gracile fasciculi in the spinal cord, and the existence of nucleocytomegalic cells in the anterior pituitary gland. These neuropathological findings correlated with previously reported cases of AT. In addition, spongy degeneration was found, predominantly around the blood vessels in the cerebral cortex. Diffuse spongy degeneration and multiple foci of coagulative necrosis with calcification were noted in the white matter. Abnormal vasculature was noted in both degenerative and necrotic areas in the cerebral cortex and in the white matter. The vessels at the center of the areas of spongy degeneration in the cerebral cortex had irregularly arranged and enlarged smooth-muscle-cell nuclei and a distorted, narrow lumen. The vessels present in the white matter were hyalinized. To our knowledge, these vascular abnormalities in the brain parenchyma have not been reported previously.
