A deficiency of the major serum alpha1-globulin, the alpha1-antitrypsin, was first described in five patients by Laurell and Eriksson in Sweden in 1963. It soon became obvious that severe alpha1-antitrypsin deficiency was familial, and highly associated with chronic lung disease, having its onset in the third or fourth decade of life. Since the early descriptions of this common deficiency state, it has become clearly associated with familial emphysema in some families, familial infantile
cirrhosis
in others, and occasionally with a combination of childhood lung and liver disease in siblings. For the pediatrician, severe alpha1-antitrypsin deficiency now enters into the differential diagnosis of both chronic pulmonary disease in childhood and obstructive jaundice in the newborn period; In addition, low levels of alpha1-antitrypsin in serum are characteristic of
respiratory distress
syndrome, and elevations of this protein may be found in a variety of clinical situations. The, alpha1-antitrypsin probably functions as a major control protein against the tissue-damaging effects of both endogenous and exogenous enzymes. This review will cover several basic and clinical features of this protein with respect to its importance in pediatrics.

The earliest written report of selenium poisoning is thought to be the description by Marco Polo of a necrotic hoof disease of horses that occurred in China in 13. century. However recognition of Se as toxic principle come in the early 1930s. Severity of Se poisoning depends on chemical forms of the element, species of animals and routes of administration. The soluble Se salts (Na2SeO3 and Na2SeO4) appear to be among the more toxic compounds; the Se inherent in grains and selenoamino acids (selenomethionine and selenocystine) appear to have relative moderate toxicity; the poorly soluble forms (e.g., elemental Se, Na2Se, SeS2 and diphenyl selenide) are among the least toxic of the Se compounds. In general, toxicity of Se compounds are substantially less when they are administered orally than when they are given parenterally. Rosenfeld and Beath described three clinical types of Se intoxication: acute selenosis, subacute selenosis (i.e., blind staggers type), and chronic selenosis (i.e., alkali disease type). Acute poisoning occurs when high Se content plants are consumed in large quantities within short period. Accidental acute poisoning occurs as consequence of errors in formulation of a Se supplemented diet. The most characteristic sign of acute selenosis is garlic breath due to the pulmonary excretion of volatile Se metabolites. Other signs include lethargy, excessive salivation, vomiting, dyspnea, muscle tremors and
respiratory distress
. Pathological findings are: congestion of the liver and kidney, fatty degeneration and focal necrosis of the liver, endocarditis and myocarditis. Subacute selenosis ("blind staggers") occurs as a consequence of exposure to large doses of Se over a longer period of time and manifests with neurological signs (e.g., blindness, ataxia, disorientation) and
respiratory distress
. This form of selenosis is most frequently observed in grazing animals that have consumed Se-accumulated plants. Chronic selenosis ("alkali disease") comes about when animals consume moderate levels of Se (more than 5 mg/kg and less than 40 mg/kg) for period of weeks or months. The usual clinical signs of chronic selenosis in horses, cattle and swine are: loss of hair (horses and cattle lose long hair from the mane and tails), emaciation, hoof lesions and lameness. In advanced cases
liver cirrhosis
, atrophy of the heart and anemia occur. In swine symmetrical poliomyclomalacia of cervical and lumbal/sacral spinal cord segment has been seen. Sheep seen to be more tolerant and get milder form of the disease. They lose appetite and have reduced gain. In growing chicks reduced gain and feed intake, rough feathers, and characteristics of nervousness has been observed. Reduced egg production, embryonic deformations and reduced hatchability has been observed in hens.(ABSTRACT TRUNCATED AT 400 WORDS)

Current management of hemorrhage in cirrhotic patients is disappointing, probably because it deals only with the portal hypertension, while the coagulation disorders are neglected. Some new suggestions can be made : 1) Hemorrhage originates in coagulation disorders. The mechanical lesion of the mucosa is only the opportunity for these disorders to become apparent. The lesion may be : infrequently, a ruptured esophageal varix or a gastroduodenal peptic ulcer ; a lesion of the cardia (hiatal hernia, reflux, esophagitis, minimal traumatic tears) ; a gastric anomaly (hemorrhagic gastritis, superficial ulcerations, petechiae) ; in some cases no mucosal lesion is apparent. 2) Any widespread liver disease results in lasting hypercoagulability which is responsible for : permanent lysis, consumption, DIC. The spleen is responsible for the functional alteration of the platelets. Splenectomy is followed by permanent recovery. 3) Changes involving the platelets are responsible for most hemorrhages. Thrombopenia and severe anomalies of platelet aggregation are common findings in
liver cirrhosis
. Further deterioration can be induced by acetylsalicylic acid, especially if it is absorbed after an immoderate ingestion of alcohol. Emergency treatment consists in platelet transfusions. 4) Stasis in the portal system may, however, result in permanent activation of coagulation. 5)
Cirrhosis
results in chronic hypercoagulability and severe platelet deterioration. Any stress involving coagulation mechanisms may therefore induce hemorrhage : infection, acetyl salicylic acid,
respiratory distress
, estrogens, massive transfusion. It is always dangerous to "feed" consumption or to restrain lysis. 6) Coagulation tests should be performed rapidly, in order to evaluate hypercoagulability, consumption, lysis, and evidence of DIC ; FDP can probably be responsible for inflammatory changes in the liver and spleen. 8) Coagulation disorders are permanent since the hepatic alterations are irreversible.

The cardiorespiratory dynamics following hepatic resection was investigated with the use of Swan-Ganz catheter in 34 patients with major hepatic resection. In the patients without
cirrhosis
or jaundice, cardiac index (CI) appeared to decrease with increased systemic vascular resistance (SVR) during the first postoperative day. CI tended to increase on the second or third postoperative day with normal SVR. In the majority of the patients without
hepatic cirrhosis
or jaundice who underwent more than 50% hepatectomy the circulating blood volume decreased immediately after the operation and increased after the second postoperative day. In the cirrhotic patients, hyperdynamic state was noted pre- and post-operatively, and was prominent in the cases with poor prognosis. These patients had relatively higher pulmonary arterial and wedge pressure, and were liable to yield to cardiorespiratory insufficiency by overhydration. In the jaundiced patients, the patterns of hemodynamic change were similar to those of the patients without
cirrhosis
or jaundice except for decreased SVR. The jaundiced patients did not develop severe
respiratory distress
in spite of having lower PO2 and higher AaDO2.

Five fatal cases of Japanese patients with type 1 Gaucher disease were studied. The causes of death included hemorrhage secondary to esophageal varices (two cases),
respiratory distress
(one case), hepatic failure (one case) and postoperative sepsis (one case). All of the patients had previous splenectomies, four patients had bone involvement and
hepatic cirrhosis
. The identified Gaucher genotypes were 1448C/1213G, 1603T/1603T, 1448C/1390G, and 1213G/1213G. The prognosis of type 1 Gaucher disease is generally good. We propose that patients with a similar clinical course and genotype to those presented in the present study should receive prompt comprehensive treatment. Patients with the 1213G mutation, pulmonary and liver involvement and a previous splenectomy should be considered as candidates for early vigorous treatment.

The acute
respiratory distress
syndrome developed twice within 4 months in a patient with
liver cirrhosis
and diabetes mellitus. The diagnosis was made from the diffuse alveolar shadows seen on a chest X-ray film and a lung injury score of 3.3. The initial episode resolved quickly with steroid pulse therapy. The second episode resolved to some extent after the same therapy, but the patient died of hepatic and renal failure followed by acute pneumonia. The causes of the first and second episodes were considered to be different and the outcome depended on liver and kidney function. We report this case because the acute
respiratory distress
syndrome rarely occurs within 4 months.

We describe two cases of pneumonia caused by Sho-saiko-to. Patient 1 was a 61-year-old man with type-C
liver cirrhosis
. About 50 days after starting to take Sho-saiko-to, he complained of fever and diarrhea, and progressive dyspnea developed. Analysis of arterial blood obtained in the emergency room showed severe hypoxemia:, PaO2 26 Torr. A chest radiograph and a CT scan showed bilateral diffuse fine granular and ground-glass opacities predominantly in the upper lung fields. Despite repeated pulse therapy with methylprednisolone and aggressive medical treatment including mechanical ventilation, the patient remained in
respiratory distress
, which was later complicated by gastrointestinal bleeding. He died on the 45th hospital day. The bronchoalveolar lavage contained abnormally high fluid percents of lymphocytes and neutrophils. Postmortem examination of the lungs revealed alveolar septal thickening, marked hyperplasia of type 2 pneumocytes, and no hyaline membrane formation. Patient 2 was a 68-year-old man. Eighty days after he began taking Sho-saiko-to, he presented with a 4-day history of shortness of breath accompanied by fewer and progressive coughing. On arrival of the hospital, arterial blood gas analysis showed mild hypoxemia (PaO2, 61 Torr) and a chest radiograph revealed bilateral irregular infiltrates in the lower lung fields. Analysis of bronchoalveolar lavage fluid showed an abnormally high percent of lymphocytes (especially CD8 + lymphocytes), and examination of a biopsy specimen revealed exudates of fibrin and neutrophils in the alveolar spaces and patechy intraluminal organization. The response to prednisolone was good and he was discharged on the 40th hospital day in stable condition. Drug lymphocyte stimulation tests of peripheral blood to Sho-saiko-to were positive in both patients. Patients 2 was though to have a typical case of Sho-saiko-to-induced pneumonia, patient 1 was thought to have fulminating variant of this disease.

Several recent trends in the vital statistics of the United States continued in 1996, including an increase in life expectancy and declines in infant mortality, births to teenage mothers, age-adjusted death rates, and death rates for children and adolescents. In 1996, there were an estimated 3 914 953 births in the United States. The preliminary birth rate remained unchanged at 14.8 births per 1000 population, and the fertility rate, births per 1000 women 15 to 44 years of age, was essentially the same at 65.7. Fertility rates rose slightly for most racial and ethnic groups except black women, for whom the rate hit a historic low of 70.8. Overall, fertility remains particularly high for Hispanic women, although there is considerable variation within this heterogenous group. For the fifth consecutive year, birth rates dropped for teenagers. Birth rates for women >/=30 years of age continued to increase. The birth rate for unmarried women declined 1% in 1996 to 44.6 births per 1000 unmarried women, continuing the decline noted in 1995 for the first time in 2 decades. The percentage of women who began prenatal care in the first trimester rose in 1996 to 81.8%, whereas the percentage with late (third trimester) or no care dropped to 4.1%. The rise in timely prenatal care was greatest for black and Hispanic women. The percentage of low birth weight (LBW) infants reached 7.4% in 1996, its highest level since 1975. The very low birth weight rate remained unchanged at 1.4%. The rise in LBW occurred primarily among white women, whereas the LBW rate for black women dropped to 13.0%, the lowest rate reported since 1987. The rise among white women is only partially a result of increases in multiple births, because LBW rates have also risen among white singleton births. The multiple birth ratio rose again in 1996 by 2%, as it has since 1980. The rise was particularly large for higher-order multiple births. Infant mortality reached an all time low level of 7.2 deaths per 1000 births, based on preliminary 1996 data. Neonatal and postneonatal rates declined, as did rates for both black and white infants. National birth weight specific mortality rates are reported here for the first time. In 1995, 63% of infant deaths occurred to the 7.3% of the population that was born LBW. The four leading cause of infant death were congenital anomalies, disorders relating to short gestation and unspecified birth weight, sudden infant death syndrome, and
respiratory distress
syndrome, accounting for more than half of infant deaths in 1996. Despite the declines in infant mortality, the United States continues to rank poorly in international comparisons of infant mortality. Expectation of life at birth reached a new high in 1996 of 76.1 years for all gender and race groups combined. Age-adjusted mortality rates declined in 1996 for diseases of the heart, malignant neoplasms, cerebrovascular diseases, accidents and adverse effects, chronic liver disease and
cirrhosis
, and suicide. They rose, as in the past several years, for chronic obstructive pulmonary diseases, diabetes mellitus, and pneumonia and influenza. For the first time since human immunodeficiency virus infection was created as a special cause-of-death category in 1987, death rates for human immunodeficiency virus infection declined from 15.6 in 1995 to 11.6 in 1996. The homicide rate also declined, as it has since 1991. Death rates for children between 1 and 19 years of age declined in 1996, with an estimated 29 183 deaths to children. Unintentional injury mortality has dropped by approximately 50% among children and adolescents since 1979, although it remains the leading cause of death for all age groups of children from 1 to 19 years. Homicide was the fourth leading cause of death for children 1 to 4 and 5 to 9 years of age, the third leading cause for children 10 to 14, and the second leading cause for 15 to 19 year olds.

The independent effects of chronic disease, age, severity of illness, lung injury score (LIS) and etiology, and preceding nonpulmonary organ-system dysfunction (OSD) on the outcome of acute lung injury (ALI) have not been examined in an exclusively medical-intensive-care-unit (MICU) population. Therefore, 107 consecutive MICU patients with ALI (76% with acute
respiratory distress
syndrome [ARDS]) were prospectively investigated. The impact of comorbidities, age > 65 yr, acute physiology score (APS), LIS, etiology of ALI, and OSD on hospital survival were studied. The overall mortality was 62 of 107 patients (58%), including 47 (58%) with ARDS. With univariate analysis, age > 65 yr, organ transplantation, human immunodeficiency virus (HIV) infection, active malignancy, chronic steroid use, and a septic or aspiration-related etiology of ALI were associated with a > or = 1.2-fold greater relative risk (RR) of hospital mortality. With multiple logistic regression, independent predictors of hospital death were age > 65 yr, organ transplantation, HIV infection,
cirrhosis
, active malignancy, and sepsis. APS, LIS, aspiration-related etiology of ALI, preceding OSD, and other comorbidities were not independently predictive of hospital death. Multivariate analysis of the ARDS cohort showed similar results, although
cirrhosis
and malignancy did not reach statistical significance. We conclude that comorbid conditions, older age, and sepsis etiology are independent predictors of hospital death in exclusively MICU patients with ALI (76% of whom satisfied criteria for ARDS). These factors should be considered in analyzing studies of new therapies and interpreting trends in mortality for ALI and ARDS.

In the present review piece, we analyze the formation of free radicals as a consequence of the cellular metabolism in aerobe organism, and the beneficious and harmful actions thereof on cellular structures. The balance existing between free radicals and the so-called antioxidant defenses, is a key factor for preventing the development of noxious processes at the cellular and tissue level. In accordance with the present scientific knowledge, the excessive production of free radicals in the organism, and the imbalance between the concentrations of these and the antioxidant defenses, may be related to processes such as aging and several diseases, among which we find cancer, ischemic processes, senile dementia, diabetes, pulmonary and pancreatic diseases, lupus erythematosus,
cirrhosis
, intestinal inflammatory disease, multiple sclerosis, arthritis, arteriosclerosis, cardiovascular disease, diseases of the central nervous system and the brain. According to the results of numerous research works conducted with the administration of several molecules with an antioxidant activity, one is beginning to see what their role will be in the pharmacological therapeutics for the treatment of a large number of patients such as those with burns, traumas, septics, shock, surgery, transplantation, radiation or chemotherapy,
respiratory distress
syndrome, AIDS, etc. We may possibly be facing a therapeutic tool which is of great interest in the clinical area, which shall be developed in the near future, as clinical trials which permit confirmation of their efficacy are conducted.
