Twelve patients with advanced malignant disease were entered onto a Phase I study of escalating doses of beta-interferon serine given by 4-h i.v. infusion twice a wk. Three patients each were entered at starting doses of 0.01, 1, 10, and 30 million units (MU)/m2. Doses escalation within individual patients was allowed to a maximum dose of 400 MU/m2. Fever, chills, fatigue, and acral cyanosis were commonly seen and increased in frequency at higher doses. Myalgia, nausea, diarrhea, headache, and confusion were seen at lesser frequencies. Mild leukopenia, paresthesia, infusion site erythema, and hypotension were each seen in one patient. No conventional maximal tolerated dose could be defined, since several patients underwent escalation to the highest allowable dose and seemed to develop tolerance to acute toxicities. However, a maximal starting dose of 10 MU/m2 was identified, such that those begun at this level or below tolerated semiweekly dose escalation, while those begun at 30 MU/m2 could not tolerate continued therapy. Detectable serum interferon levels were noted during treatment at 10 and 30 MU/m2, the levels at which significant toxicity also first appeared. A maximal starting dose of 10 MU/m2, with gradual escalation as tolerance to side effects develops, is suggested if therapy with high-dose beta-interferon serine is given by 4-h infusion.

In 325 cases of industrial chemical cyanosis notified to Her Majesty's Factory Inspectorate for 1961-80 the incidence of poisonings showed considerable seasonal variation with substantially greater numbers occurring in the summer months. A correlation between the number of poisonings in any one year and the hotness of that summer was also shown. The vast majority of incidents occurred during the manufacture of chemicals or dyestuffs, and two particular workplaces were responsible for 70% of the cases. Poisoning by amino compounds appear to produce early cyanosis whereas poisoning by nitro compounds tended to produce delayed cyanosis. These latter compounds were also more likely to produce anaemia. Methaemoglobin was determined in 45% of cases with results ranging from less than a few per cent to over 50%. Despite concentrations of MetHb over 50%, several workers complained only of headache and their blue appearance.

Every time the tuberculosis is present and it is to be included in the differentialdiagnosis if the occasion arrises. In the anamnesis it is necessary to pay attention to specific diseases and the risk groups like patients with "21-day-cough", silicotics, "Contrast-articularis bronchitics", diabetics, so-called "persons with fibrotic lesions" and patients with frequent influenzal infections. The symptoms unclear gastric distress, want of appetite, indifferent loss in weight, uneasiness, slight vertigo and fast tiredness already give further references. Breath-pain, haemoptysis and subfebrile temperatures are already severe symptoms. A thorax X ray-photograph, tuberculin test, heamogram, sedimentation test and intensive search for mycobacteria, belong to the diagnosis. In extrapulmonary foci the search for mycobacteria is to try by swab, puncture, control of urine and menstrual blood. It is possible, that a histologic corroboration will be necessary. Unclear fever, headache and vomiting with or without dyspnoea, cyanosis and diaphragmatic lowness indicate a ocular reflection, liver biopsy and, in special case, a lumbar puncture without delay. Sooner or later the course of an unrecognized phthisis can result in death. It is necessary to fill up the gap between welltime diagnosis and death by unknown tuberculosis. That means: Thorough knowledge of matter, insight into the disease-course and inducement of all necessary diagnostic possibilities.

The clinical courses of 31 episodes of brain abscess and one episode of meningitis occurring in patients with hereditary hemorrhagic telangiectasia are reviewed. Pulmonary arteriovenous malformations were demonstrable in all but two patients and presumably permitted septic microemboli to evade the normal pulmonary capillary filter and lodge in the brain. Obtundation, headache, visual disturbances, hemiplegia, and seizures were the most common presenting features. Cyanosis, clubbing, polycythemia, and hypoxemia were routinely encountered, but leukocytosis and fever were present in a minority of cases, and all blood cultures were sterile. Anaerobic and microaerophilic streptococci were the commonest pathogens found in the brain abscesses. Thirteen patients died, and patients without abscess drainage or with delayed diagnosis had a higher mortality rate. A brain abscess may develop in approximately 1 percent of patients with hereditary hemorrhagic telangiectasia, and awareness of this risk should lead to early investigation of any patient with hereditary hemorrhagic telangiectasia who has neurologic symptoms.

The authors experienced with four cases of brain abscess, one of which ruptured into the lateral ventricle. Two cases were treated conservatively and the remaining two were treated surgically. All cases recovered satisfactorily. Case 1: A 30-year-old man with congenital cyanotic heart disease was admitted on Oct. 4, 1979, because of convulsion. Physical examination revealed motor aphasia, right hemihypesthesia, cyanosis, clubbed finger and continuous heart murmur. CT scan showed a ring-enhance mass lesion in the left temporal lobe. Although transient deterioration of the clinical course was observed, he improved satisfactorily after medical treatment of 20 days. Case 2: A 54-year-old man with left homonymous upper quadrantanopia and systolic heart murmur was admitted on Sept. 17, 1979. alpha-streptococcus was detected in the culture of his arterial blood. Vegetation near the mitral valve was revealed by ultrasonic cardiogram. CT scan showed an irregular and ill-shaped ring-enhanced mass in the left temporoparietal region. A saccular aneurysm in the insular portion of the posterior parietal artery was seen on the left carotid angiogram. He was also treated medically and the abscess was gradually reduced and the aneurysm disappeared. Case 3: A 28-year-old man complaining of headache, nausea and vomiting was admitted on Dec. 1, 1979. Physical examination revealed nuchal stiffness, right homonymous hemianopia and bilateral choked disc.(ABSTRACT TRUNCATED AT 250 WORDS)

Liz... Josiane, a 9 year old girl, was admitted with a 24 hours history of severe headache and vomiting. On admission she was conscious, irritable and complained of a severe headache. Clinical examination revealed a right hemiparesis with cyanosis of the lips and extremities and clubbing of the fingers, all consistent with chronic hypoxia. Cardiovascular examination was normal apart from a systolic murmur which could be heard posteriorly under the left scapula. There were no angiomatous or telangiectatic lesions of the skin. A blood examination revealed a raised ESR, a marked polycythaemia with a decreased arterial oxygen tension. Chest x-rays showed the presence of an irregular well delineated opacity in the posterior basal segment of the left lower lobe. This opacity was confluent with the ipsilateral hilum and was suggestive of a pulmonary arteriovenous fistula. An intracranial space occupying lesion in the left temporal region of the brain was revealed by electroencephalographic and CT scan investigations; this proved to be an abscess which was surgically removed with no subsequent complications. Further radiological investigations of the chest revealed the pulmonary lesion was an arteriovenous aneurysm occupying the whole left inferior lobe. This was removed at thoracotomy three months after the acute neurological event. The results of respiratory function and regional isotopic investigations before and after surgery will be discussed.

A case of acute Dapsone intoxication due to voluntary ingestion of 3 g of this drug as a suicide attempt is described. A severe methemoglobinemia developed, accompanied by intense cyanosis, dyspnea, headache, and nausea. Subsequently, significant sulfhemoglobinemia responsible for prolonged cyanosis was observed, as well as mild hemolytic anemia. Relapses of methemoglobinemia after methylene blue treatment required repeated administration of the reducing agent. The need of a careful follow-up for several days in this type of intoxication is emphasized.

Four patients showing classic physical stigmata of traumatic asphyxia were studied. Cervicofacial cyanosis and edema, subconjunctival hemorrhage, and multiple ecchymotic hemorrhage of the face, neck, and upper part of the chest were documented. Admission Glasgow coma scale scores ranged from 8 to 15. All but one had no associated injury. Skin discoloration resolved within 3 weeks. Complete resolution of subconjunctival hemorrhage occurred 1 month later. In our series, sore throat, hoarseness, dizziness, numbness, and headaches were common. Profound lower leg pitting edema, hemoptysis, hemotympanum, and transient visual loss were noted. Chest radiographic findings were normal in all patients. Microscopic hematuria was noted in one patient. Diagnosis is made from the history and characteristic appearance of the patient. Treatment is directed to the associated injury. Oxygen supplement with head elevation to 30 degrees is the mainstay of treatment. If the patient survives the initial insult, the prognosis is excellent.

Among 182 episodes with ARF (PaCO2 > 50 torr) in 400 episodes of COPD patients who were admitted to Chulalongkorn Hospital during the period 1982 to 1986, despite conservative treatment, 66 developed severe acute respiratory failure requiring assisted ventilation. Patients with a history of chronic cough, pneumonia as a precipitating factor and more severe ARF on admission, as indicated by palpitation, headache, cyanosis, alteration of consciousness, cor-pulmonale and decompensated acidosis (pH < 7.30), were likely to require mechanical ventilation. Indications for mechanical ventilation were carbon dioxide narcosis (43 episodes), severe hypoxemia despite on a high FIO2 (one episode), various combination parameters of respiratory muscle fatigue, cardiovascular instability (22 episodes). The major complications of mechanical ventilation were pneumonia, sepsis, pneumothorax, UGI bleeding of 16, 8, 5 and 9 episodes, respectively. The average duration of assisted ventilation and hospitalization were 15.8 and 19.02 days, respectively. The mortality rate was 50 per cent in the mechanical ventilation group compared with 9.8 per cent in the non-mechanical ventilation group. Increased mortality rate was found in those with pneumonia as the precipitating factor (68.4 vs 14.3%, respectively, in comparing the two groups). Complications of mechanical ventilation, which included pneumonia, sepsis, fluid overload, hyponatremia and persistent acidosis, were high-risk factors for the non-surviving group.

Patients with neuromuscular disease may suffer from nocturnal respiratory failure despite normal daytime respiratory function. The physiological reduction in muscle tone during sleep may be life-threatening in a patient with impaired muscle strength. Nocturnal respiratory failure may occur in patients with the postpolio syndrome, amyotrophic lateral sclerosis, myasthenia gravis, myotonic dystrophy, and muscular dystrophy. Diagnosis of obstructive, central and mixed apneas, hypopneas, and hypoventilation is best made using polysomnography. Therapeutic options include noninvasive ventilation such as continuous positive airway pressure, bilevel positive airway pressure, intermittent positive pressure ventilation and, rarely, tracheostomy, oxygen, or protriptyline. Evaluation by a sleep specialist should be initiated in any neuromuscular patient with nocturnal symptoms such as air hunger, intermittent snoring or breathing, orthopnea, cyanosis, restlessness, and insomnia. Daytime symptoms may include morning drowsiness, headaches and excessive daytime sleepiness. Polycythemia, hypertension, and signs of heart failure may also be seen. Effective treatment is available, and may improve the quality of life, and possibly increase survival.
