Bacterial toxicosis/toxic shock syndrome as a contributor to morbidity in children with burn injuries.

When a child with a thermal injury suddenly becomes unwell, it is often difficult to obtain an accurate diagnosis in the early stages of the illness. Out of 71 children admitted to our burns unit over a 15-month period, 13 became acutely toxic. Most of the cases had relatively small burns and the exact reason for their sudden deterioration was not apparent in the immediate stages. Several children required admission to the intensive therapy unit and there was one death. The number of children experiencing this significant morbidity over a relatively short period of time prompted us to perform a detailed retrospective study to ascertain the exact cause of the deterioration and to identify any patterns in their presenting signs and symptoms. There was considerable variation in the clinical picture of the children who developed the toxicosis, however, several features were frequently observed which resembled those seen in the toxic shock syndrome (TSS). In order to be more specific, we applied the criteria for TSS as defined by the Centres for Disease Control (CDC) to each of the 13 children. All of the criteria were noted in six children and the majority in the other seven. This was a much higher incidence than we would normally have expected. The clinical features of children with TSS are not always easy to distinguish from those observed in other illnesses. We therefore explored the possibility of alternative diagnoses that may have caused the toxicosis in these children. The mortality associated with TSS can be high, especially if there is a delay in recognition and subsequent management of the disease. Clinicians should be alerted to the fact that TSS is probably more prevalent than previously thought and should practise with a high index of suspicion in any child with a burn whose clinical condition suddenly deteriorates.

[Specific brain antigens--an index of the permeability of the hemato-encephalic barrier in comatose states in children].

In 39 children with coma caused by infectious toxicosis, purulent meningoencephalitis and closed head trauma the brain-specific antigens (L1M and L2M globulins) contents were studied in the blood serum and cerebrospinal fluid (CSF). On days 3 to 5 after the head trauma L1M and L2M were found irregularly. In meningoencephalitis L1M and L2M were detected with a lesser delay. In infectious toxicosis L1M and L2M appeared in blood serum and CSF regularly and early. The data suggest that appearance of brain-specific antigens in blood and CSF in coma reflect a rise in the blood-brain barrier permeability to CSF-blood transport.

[Heparin and antiheparin in childhood. 2. Clinical relevance of the phenomenon of heparin resistance].

Investigations of the content of platelet factor 4 in different thrombocyte lysates and platelet-rich plasma after induced release reaction were aimed at checking the efficiency of the own antiheparin measuring system. In this connection, the age dependent dynamics of platelet factor 4 could be first discovered. In platelet-poor plasma of healthy grown-up test persons there was an evidence of antiheparin titres which were five times higher as compared with those persons born maturely. All patients with disseminated intravascular coagulation processes of different aetiology, however, will have significantly increased values. As demonstrated in two children with hyperpyretic toxicosis, the liberated platelet factor 4 will only show a short plasma half decay period. From investigations made for refinding heparin in the plasma after in vitro addition the conclusion can be drawn that, in addition to platelet factor 4, even unspecific adhesions of heparin to certain plasma proteins may be responsible for increasing heparin resistance.

Placental villous edema: a possible cause of antenatal hypoxia.

This study was undertaken to determine the relationship between the placental villous edema and the characteristic sequelae of antenatal hypoxia, i.e. the need for resuscitation at birth and low pH values in umbilical arterial blood. Placental villous edema was recognized by finding of open spaces within the cytoplasm of intervillous cells and in the interstitium of the villi. The percentage of edematous villi was significantly higher in the group of newborns requiring resuscitation. The severity of the edema had a positive correlation with the need for resuscitation at birth and with the arterial blood pH values in the umbilical cord. Placenta praevia and maternal toxicosis were associated with high percentage of edematous villi. It is suggested that edema fluid interposed a barrier to gas exchange between mother and fetus. The capillaries were blocked by compression leading to reduction in blood flow through the villi. These abnormalities, if widespread, may reduce gas exchange. It is suggested that hypoxia could partly be prevented by preventing the development of placental villous edema.

[Perinatal pathology and risk groups in postnatal ontogeny].

Perinatal pathology may become the cause of diseases in children and adults. Cardiovascular system of the foetus and placental vessels are examined in the toxicosis of the pregnancy, hypertension of pregnant mothers, immunological system and sex glands in large foetus, thyroid and sex glands of newborns. It is suggested that early atherosclerosis, myocardiopathy, sexual disturbances, endocrinopathy, immunodeficient states are consequences of pathological or "prepathological" development of certain organs and systems of the foetus.

[Course of pregnancy, delivery and newborn status in case of maternal tuberculosis].

Course of pregnancy, delivery and newborns status were analyzed for 77 women with tuberculosis. The data were compared with analogical data of 72 healthy women. Almost fifty percent (49.3%) of patients were treated with antituberculous drugs in pregnancy. Eighty percent of women with tuberculosis gave birth of mature healthy newborns. Some cases of preterm rupture of membranes, preterm or postterm delivery and another complications were observed, but there was no significant difference comparing to healthy women. Anemia and congenital anomalies were significantly more common in tuberculosis group. Anemia was explained by suppressive influence on the appetite and liver function of pregnant women by specific baciliar toxicosis, antituberculous drugs and insufficient resorption of nutrition ingredients (especially iron). We are very concerned about growing number of developmental anomalies of newborns in women with tuberculosis, such as spina bifida, inherited luxation of hip joint and other abnormalities. There is a need for additional data to make a general conclusion. But it is clear that in medical institutions all women with tuberculosis must get the information how to plan pregnancy.

[Nerve tissue-specific proteins in the assessment of the permeability of the hemato-encephalic barrier in comatose states in children].

The role of functional state of hematoencephalic barrier (HEB) was estimated in terms of development of pathological process in coma. The quantitative determination of neurospecific protein (NSP), exactly of alpha 1 and of alpha 2 cerebral globulins (produced by astrocytes and oligodendroglial cells) was used for estimation of HEB state. The clinical examination of 138 children in comatose state caused by different factor (meningitis, encephalitis, cerebrocranial trauma, infectious toxicosis) was performed. Enzyme immuno-assay of alpha 1 and of alpha 2 cerebral globulins allowed to control HEB's functional state objectively in "brain-blood" direction: in cases of alteration of HEB's function the autoantibodies to NSP may penetrate into cerebral tissue and cause nonspecific reaction in form of edema or inflammation. The membrane stabilizing effect of Dexamethazone was established.

Triiodothyronine radioimmunoassay and its application to thyroid disorders.

An accurate, highly sensitive triiodothyrone (T3) radioimmunoassay system is described. Direct measurement in serum is made possible by the use of T3-free serum for standards, and blocking of T3 binding to thyroxine (T4)-binding globulin with salicylate. T4 cross reactivity was less than 0.3%. Mean T3 levels in 55 euthyroid, 32 hyperthyroid and 19 primary hypothyroid patients were 1.46 +/- 0.17, 5.34 +/- 1.86 and 0.49 +/- 0.34 (SD) ng/ml, respectively. T3 was found to be a more sensitive index than T4 in hyperthyroidism; in hypothyroidism it overlapped with euthyroidism. The presence of goiter had no effect on T3 concentrations in euthyroid patients. Among the patients studied, eight were found to have T3 toxicosis, including two patients with recurrent thyrotoxicosis. A significant T3 elevation was also found in euthyroid patients after thyroidectomy whereas T4 remained normal. The extent of T4 and T3 elevation was similar during the initial phase of subacute thyroiditis. There were significantly lower T3 values and higher thyroid-stimulating hormone values in umbilical cord blood than in maternal blood. In two euthyroid subjects, thyrotropin-releasing hormone stimulation caused a 50% rise in T3 levels and no change in T4 levels over a 2-h period.

[Risk of intrauterine infection of the human fetus with Coxsackie viruses in pregnancy complicated by late toxicosis and pyelonephritis].

During virological examinations of 144 pregnant women including 85 women with complicated course of pregnancy Coxsackie A viruses were isolated from the blood or identified in the cells of urinary tracts in 60.3% of the cases of nephropathy, in 68.3% of the pregnant women with pyelonephritis, and in 8.5% of normal subjects. The groups of the pregnant women under comparison did not differ significantly in the rate of finding of other viruses. Coxsackie A viruses were also isolated from the placenta and amniotic fluid in 3 out of 4 cases examined in late toxicosis, were found in the kidneys of the fetus from a woman with pyelonephritis and in cells of the urinary tracts of 13 out of 19 babies (68.4%) born to women with complicated course of pregnancy. The hypothesis of the etiological association of nephropathy and pyelonephritis in pregnant women with activation of chronic Coxsackie virus infection and of the high risk of infection of the fetus with these viruses in the described complications of pregnancy is discussed.

Clostridium perfringens type A enterotoxin (CPE): more than just explosive diarrhea.

The bacterial pathogen Clostridium perfringens is the most prolific toxin-producing species within the clostridial group. The toxins are responsible for a wide variety of human and veterinary diseases, many of which are lethal. C. perfringens type A strains are also associated with one of the most common forms of food-borne illness (FBI). The toxicosis results from the production and gastrointestinal absorption of a protein-enterotoxin known as CPE. The regulation, expression, and mechanism of action of CPE has been of considerable interest as the protein is unique. CPE expression is sporulation associated, although the mechanism of cpe-gene regulation is not fully elucidated. Cloning studies suggest the involvement of global regulators, but these have not been identified. Although very few type A strains are naturally enterotoxigenic, the cpe gene appears highly conserved. In FBI strains, cpe is chromosomally encoded; whereas in veterinary strains, cpe may be plasmid-encoded. Variation in cpe location suggests the involvement of transposable genetic element(s). CPE-like proteins are produced by some C. perfringens types C and D; and silent remnants of the cpe gene can be found in C. perfringens type E strains associated with the iota toxin gene. CPE has received attention for its biomedical importance. The toxin has been implicated in sudden infant death syndrome (SIDS) because of its superantigenic nature. CPE can destroy a wide variety of cell types both in vitro and in vivo, suggesting that it could have potential in the construction of immunotoxins to neoplastic cells. It is obvious that CPE is an interesting protein that deserves continued attention.

[Hormonal regulation of glycemia and metabolic adaptation of newborn babies with intrauterine hypotrophy].

The content of hormones that regulate carbohydrate metabolism was studied during the early neonatal period in 80 full-term neonates with intrauterine hypotrophy. Early application to the breast (2 to 6 hours after the birth) was shown to promote the normalization of the hormonal content. The levels of blood serum C-peptide in the newborn depend on the degree of the rise of the mother's body weight during pregnancy and the presence of toxicosis. The levels of cortisol, somatotropic hormone, immunoreactive insulin and C-peptide were determined by the degree of morphological immaturity of the tissues whereas the content of STH and cortisol by the intensity of hypotrophy as well. The moment of the birth and the early neonatal period of children with intrauterine hypotrophy is characterized by a decrease of the activity of lactate dehydrogenase, alpha-hydroxybutyrate dehydrogenase, creatine kinase and aspartate aminotransferase.

The CNS symptoms of rotavirus infections under the age of two.

BACKGROUND: Since isolation of the Rotavirus (RV), there is rapidly growing concern about the possible involvement of RV in Central Nervous System (CNS) disorders, especially in Japan. We looked for symptomatic CNS involvement in a large series of RV infections and it's possible risk factors in a European setting. METHODS: Two-year retrospective survey based at the University Children's Hospital of Freiburg, Germany, a secondary and tertiary care centre with a urban and rural catchment area of 400,000 people. First, the case records of all 366 inpatients aged under two years excreting RV were searched for signs and symptoms of CNS involvement. Second, records of all 32 patients hospitalised with meningitis/encephalitis during the study period were checked for evidence of RV infection. RESULTS: In 15 of 366 children signs of CNS involvement (seizures, meningeal and encephalitic signs) were found. They were older (p = 0.023), had higher temperatures (p = 0.001) and CRP values (p = 0.019). Five of the fifteen had underlying neurological diseases, two had an additional salmonella infection and one suffered from hypernatraemic toxicosis. In the remaining seven children, higher temperature (p = 0.037) and older age (p = 0.05) remained significant risk factors. CNS-signs occurred in 2% of RV-excreting children, a rate equal to the prevalence of febrile seizures among all inpatients during the study period (2.2%). Of all 32 patients hospitalised with a diagnosis of meningitis or encephalitis only four had their stools tested for RV, all with a negative result. CONCLUSIONS: CNS symptoms in children aged less than two years with rotavirus diarrhoea have the same clinical epidemiology as febrile seizures and thus, in general, don't need additional diagnostic procedures.

Endemic Tyrolean infantile cirrhosis is not an allelic variant of Wilson's disease.

Recently, 138 cases of infantile cirrhosis originating in several families in the Austrian province of the Tyrol were reported. This endemic Tyrolean infantile cirrhosis (ETIC) is indistinguishable from Indian childhood cirrhosis (ICC), idiopathic copper toxicosis (ICT), and resembles the early forms of Wilson's disease (WND). It has been argued that ETIC might represent an allelic variant of the WND gene, which is a copper transporting P-type ATPase (ATP7B). Assuming that ETIC results from a founder effect, a possible role for ATP7B in ETIC was investigated by association studies and haplotype sharing. Because of its lethality, the mapping of ETIC was focused on obligate gene carriers, i.e. the patients' parents. Our data indicate that ETIC is a separate genetic entity, distinct from WND.

[Clinical study of pregnant women with psychotic disorders during last 14 years in Osaka Medical College].

The clinical features and outcomes of 51 pregnancies (47 patients) complicated by psychotic disorders were studied. These patients were diagnosed as having the following psychotic disorders: 7 schizophrenias, 8 atypical psychoses, 6 mood disorders, 25 epilepsies, 4 anxiety disorders, and 1 personality disorder. The mean delivery age of women suffering from schizophrenia, atypical psychosis, and anxiety disorder was over 30 with deliveries 7-10 years after the onset of their psychoses. The predominant obstetrical complications for schizophrenias, atypical psychoses, and mood disorders were gestational toxicosis, threatened premature birth, and premature birth, respectively. Six out of eight (75.0%) patients with atypical psychosis, 4 out of 6 (66.7%) patients with mood disorder, and 2 of 4 patients with anxiety disorder became worse during pregnancy and/or postpartum. The rate of deterioration of the patients with schizophrenia was 14.3% (1/7) during pregnancy. An increasing rate of epileptic attack during pregnancy and/or postpartum were observed in 40.0% (10/25) of patients. Nine cases underwent cesarean section not due to their mental disorders but for obstetrical reasons. The present study suggests that the cooperation between obstetrician and psychiatrist, and the existence of a key person who knows the patient very well is required for a desirable outcome of the treatment.

Evolution of a neonatal gentamicin dosing protocol in a small community hospital.

The effects of conventional dosage of gentamicin of 2.5 mg/kg given every 12 hours was retrospectively investigated in a small community hospital. Consistent with previous results in large hospitals, the conventional dosage of gentamicin commonly resulted in serum concentrations associated with toxicosis. Results were compared with those obtained prospectively according to a gentamicin dosing protocol that used a formula based on gestational age. The gestational age regimen provided similar peak and significantly lower trough serum concentrations; statistical analysis indicated no demographic differences in the compared groups. Very few neonates who received gentamicin according the gestational age formula were exposed to gentamicin serum concentrations associated with an increased risk of toxicosis. An absence of any significant differences in mean peak and trough serum concentrations in subgroups of neonates treated according to the gestational age formula suggested that use of the gentamicin dosing protocol was appropriate for all neonates. The dose of 3.5 mg/kg used in the gestational age formula was predicted to have resulted in initial gentamicin peak serum concentrations > 5 micrograms/ml in nearly 90% of neonates. The experience obtained with the gestational age formula allowed revision of the gentamicin dosing protocol to provide for more cost-responsible serum concentration monitoring.

[Alcohol and pregnancy. Negative and positive effects of acute and chronic effect of alcohol on the course and outcome of pregnancy].

The attitude towards alcohol is ambiguous and mainly depending upon the role attributed to it:as a stimulant, as a pharmacon or as a drug the person may be addicted to. Acute and chronic alcohol intoxication may be followed by psychic and somatic leasons. As far as pregnancy is concerned, leasons due to chronic alcohol consume have to be considered as maternal factors of high risk to the pregnancy. Acute alcohol intoxication may be harmful for the pregnancy as well as gametogenesis and gametes and embryo. Alcohol has been used in obstetrics as an analgetic during delivery, for premedication in obstetrical operations, for elimination of edema in toxicosis, as an abortifacient and as adjuvant in termination of lactation. Critical evaluation shows that these indications are only of historical value. Today more effective and specific compounds are available and as for the narcotic effect is concerned the dosage of the new narcotics of course is more exact. Alcohol recently has been proposed as a tocolytic agent. Although today other tocolytics are available, it should be kept in mind as a substitute if the use of beta-mimetic substances is not possible. The controversy about the value of alcohol in therapy or prevention of newborn hyperbilirubinaemie is not yet resolved, but should be clarified since this therapy--if of value--would constitute one of the rare possibilities to interfere with the fetal metabolism.

[Clinical studies on cases of cardiovascular disease during pregnancy (author's transl)].

The long term follow up studies on cases of cardiovascular diseases during pregnancy or delivery were reviewed in 181 patients administrated in our clinic. The results as follows: 1. An incidence of patients with cardiovascular disease during pregnancy was 1.46 per cent as a whole, and there was increasing tendency in congenital heart disease. 2. An accidental heart failure during pregnancy was seen in 7.7 per cent and all cases with NYHA III grade had an incidence of 100 per cent. 3. The occurrence of toxicosis and SFD pregnancy were more frequently seen in group of heart disease than in controls. But, no difference was observed in spontaneous abortion or neonatal asphyxia. 4. 28 patients with Starr-Edwards prosthetic heart valves became pregnant in our clinic. In these pregnancies, 5 cases receiving with warfarin therapy resulted in 3 anomalies of new born and in 2 spontaneous abortion. So, the use of warfarin seemed to have the risk to the fetus. But omission of the anticoagulant therapy on the other hand, increased the danger of systemic embolization to the mother. 5. The follow up study by mail in some cases revealed that, as a general, pregnancy and delivery may aggravate the condition of patients, especially who had mitral heart failures.

Chronic copper toxicosis presenting as liver failure in an Australian child.

A 20 month old Caucasian male child, after a five week illness, developed liver failure which was successfully treated by liver transplantation. The explanted liver had a histology identical to that seen in Indian childhood cirrhosis and its copper content was increased tenfold. Water used to prepare the child's milk feeds came from a bore via copper conduits and at times contained 120 mumol/l of copper, eight times the recommended maximum for human consumption. Because non-Indian cases of Indian childhood cirrhosis associated with excess copper ingestion are increasingly being recognised, and as early treatment can restore normal liver morphology, we support the use of the previously suggested alternative term for this condition, ie; 'copper-associated liver disease in childhood'. Measurement of hepatic copper concentrations in all children less than six years of age who develop hepatic failure of unknown cause will increase its recognition. On diagnosis sources of increased dietary copper should be investigated to ensure that younger siblings are not similarly exposed.
