First interim progress report on the second British Institute of Radiology Fractionation Study: short versus long overall treatment times for radiotherapy of carcinoma of the laryngopharynx.

Preliminary data from a second British Institute of Radiology Fractionation Trial comparing short (less than or equal to 4 weeks) and long (greater than 4 weeks) overall treatment times are reported. The intake of patients ran from January, 1975 to December, 1985 when 611 patients with carcinoma of the laryngo-pharynx were registered in this prospective, randomized, multicentre clinical trial. No significant differences have, so far, been demonstrated between the two arms of the trial with respect to observed survival rates, tumour-free or laryngectomy-free rates. Further long-term follow-up is continuing.

Arm exercise testing with myocardial scintigraphy in asymptomatic patients with peripheral vascular disease.

Arm exercise with myocardial scintigraphy and oxygen consumption determinations was performed by 33 men with peripheral vascular disease, 40 to 74 years of age (group 2). None had evidence of coronary disease. Nineteen age-matched male control subjects (group 1) were also tested to determine the normal endurance and oxygen consumption during arm exercise in their age group and to compare the results with those obtained during a standard treadmill performance. The maximal heart rate, systolic blood pressure, pressure rate product, and oxygen consumption were all significantly lower for arm than for leg exercise. However, there was good correlation between all these parameters for both types of exertion. The maximal heart rate, work load and oxygen consumption were greater for group 1 subjects than in patients with peripheral vascular disease despite similar activity status. None of the group 1 subjects had abnormal arm exercise ECGs, while six members of group 2 had ST segment changes. Thallium-201 scintigraphy performed in the latter group demonstrated perfusion defects in 25 patients. After nine to 29 months of follow-up, three patients who had abnormal tests developed angina and one of them required coronary bypass surgery. Arm exercise with myocardial scintigraphy may be an effective method of detecting occult ischemia in patients with peripheral vascular disease. Those with good exercise tolerance and no electrocardiographic changes or 201T1 defects are probably at lower risk for the development of cardiac complications, while those who develop abnormalities at low exercise levels may be candidates for invasive studies.

Conservative surgery for early breast cancer results from a district hospital.

Wide local excision followed by radiotherapy was offered as an alternative to mastectomy to 93 women on 96 occasions. Complications attributable to the surgery occurred in 4 per cent whilst 37.5 per cent developed complications secondary to the radiotherapy. The complications were generally of a mild nature. Nine patients (9.3%) have developed regional recurrence and seventeen (17.7%) distant metastases with a mean follow up of 53.4 months.

Therapeutic effects of organic germanium.

Germanium is present in all living plant and animal matter in micro-trace quantities. Its therapeutic attributes include immuno-enhancement, oxygen enrichment, free radical scavenging, analgesia and heavy metal detoxification. Toxicological studies document Germanium's rapid absorption and elimination from the body, and its safety. Clinical trials and use in private practices for more than a decade have demonstrated Germanium's efficacy in treating a wide range of serious afflictions, including cancer, arthritis and senile osteoporosis. Germanium's anti-viral and immunological properties, including the induction of interferon, macrophages, T-suppressor cells and augmentation of natural killer cell activity, suggest its possible efficacy in treating and/or preventing AIDS.

Nodular sclerosing Hodgkin's disease in association with Gaucher's disease.

Gaucher's disease has been described in association with a number of disorders of the lymphoreticular system. The patient described in this report developed Hodgkin's disease after treatment in childhood for Gaucher's disease. A possible pathogenetic link between the two disorders is discussed, together with the role of ferritinaemia.

Differential loss of enzyme activity by vitC and iron containing proteins.

Our earlier studies showed that rabbit muscle phosphoglucomutase was irreversibly inactivated by exposure to a mixture of vitamin C, FeCl3 and O2. The enzyme lost about 70% of its phosphate (V.V. Desphande and J.G. Joshi, J. Biol. Chem. 260, 754-764, 1985). The present report shows that several other iron proteins can substitute for FeCl3 to a varying degree. The rate of inactivation by FeCl3 greater than ferritin greater than hemoglobin = hemerythrin greater than transferrin = ferridoxin = vitamin C. These iron compounds also produced dephosphoenzyme but did not dephosphorylate ATP, ADP, AMP or phospholipids.

Cloning and nucleotide sequence of a mouse erythrocyte beta-spectrin cDNA.

A rabbit monospecific antibody for mouse beta-spectrin was used to screen a mouse anemic spleen cDNA expression library. A mouse beta-spectrin cDNA clone was isolated and identified by its ability to make mouse beta-spectrin-like antigens in Escherichia coli. This clone was used to probe total RNA from various mouse tissues. Anemic spleen RNA showed two strongly hybridizing RNA species of approximately 6 and 8 kb. Two very faintly hybridizing bands of about 6 kb and 10 kb could also be seen in total mouse brain RNA. All of these bands could be detected after hybridization under both stringent and nonstringent conditions. This suggests that erythroid beta-spectrin may also be expressed in the brain. No bands could be detected in kidney, liver, or spleen RNA. Southern blot analysis of mouse genomic DNA showed a single hybridizing band after digestion with several restriction endonucleases even under nonstringent conditions. Nucleotide sequencing of the cDNA insert revealed almost complete identity between the N-terminus of the deduced amino acid sequence of the cDNA clone and the C-terminal 15 amino acids of a peptide derived from the beta-8 repeat unit of human erythrocyte beta-spectrin. The deduced amino acid sequence contained most of the conserved amino acids characteristic of the 106 amino acid repeat unit first found in human alpha-spectrin and thus provides the first evidence for a complete 106 amino acid repeat unit structure in beta-spectrin.

Apparent changes in the alignment of the femoral component in hip arthroplasties associated with limb positioning.

Three femoral components (one cemented and one uncemented straight-stem Muller and one uncemented Anatomic Medullary Locking) were placed into cadaveric or commercially available plastic femora to establish that rotation of the femur can simulate changes in femoral component alignment on the anteroposterior radiograph. The change in alignment is governed by the position of the prosthesis within the femoral canal. If the stem of the prosthesis is positioned posteriorly in the canal, external rotation simulates valgus; internal rotation results in a varus orientation. If the prosthetic stem is located anteriorly in the canal, the reverse is true. This effect was noted in all specimens for values as small as 20 degrees of rotation. Because a change in the position of a prosthesis may signify loosening, it is recommended that standardized positioning techniques be used for radiographic analysis of total hip arthroplasties.

High-dose metoclopramide and dexamethasone as an antiemetic in chemotherapy of breast cancer.

Twenty-six patients with breast carcinoma who experienced severe emesis due to chemotherapy were evaluated for the antiemetic efficacy of high-dose metoclopramide (HD-MCP) and dexamethasone (DXM). Most of the patients received the CMF (cyclophosphamide, methotrexate and 5-fluorouracil) combination chemotherapy. The MCP and DXM dosage were: 2 X 2 mg/kg and 2 X 0.2 mg/kg, respectively. In 41% of eighty evaluable courses, nausea and vomiting were eliminated altogether. The common side effects were: drowsiness, restlessness and diarrhea. HD-MCP and DXM are recommended in modified dose for preventing CMF chemotherapy induced emesis.
