A Case of Avian Tuberculosis in Sheep

A case of generalized avian tuberculosis in sheep is described. The case was somewhat unusual. No calcification and slight encapsulation together with scanty participation of epithelioid cells in the inflammations were typical features. The source of the infection, in an area where this disease is rare, is not known.     

Coexistence chez un même patient de la maladie des légionnaires et de la fièvre Q.

A case of Legionnaires'' disease associated with Q fever is presented; this is probably the first reported case of concomitant infections with Legionella pneumophila and Coxiella burnetii. The pulmonary features of the illness were not typical of either disease. The difficulties of making a diagnosis in such cases are discussed.     

A case of atypical galactosemia(author's transl)]

The case of a male infant suffering from clinical manifest galactosemia in connexion with a disease of only about 70% in uridyltransferase activity is characterized as atypical galactosemia. As compared with the described "Indiana variant" of a galactosemic female infant showing an unstable uridyltransferase activity this case demonstrates an unchanged enzyme activity still after 72 hrs. The metabolic disease of this patient clearly demonstrated that the lack of a typical pronounced reduction of enzyme activity maybe not the leading criterion for excluding the clinical diagnosis of galactosemia. In the present case only the consistent galactose-free diet lead to the decisive improvement of the clinical picture. The investigation of the family revealed the typical pattern of an autosomal recessive mode of heredity.     

Wound botulism: a life-threatening complication of hand injuries

Botulism is usually associated with the ingestion of food contaminated with Clostridium botulinum, and these organisms occasionally contaminate traumatic injuries. It is unusual for them to result in clinical infection, but when this occurs, it is a catastrophe completely out of proportion to the degree of wound injury. A case is presented in which typical manifestations of descending cranial nerve and generalized motor paralysis were noted. Prolonged respiratory and general supportive assistance was required, as is usually the case. Although mortality rates in this disease are high, recovery is usually complete in survivors and was true in this instance.     

Goldston syndrome: report of a case.

Cerebrohepatorenal malformation is a rare familial disorder characterized by typical renal lesions combined with Dandy-Walker malformation, and congenital hepatic fibrosis. In this case report, a male premie with the diagnosis of cerebrorenal syndrome or so called Goldston syndrome is presented. Besides the rarity of this syndrome, this case is the second reported patient diagnosed prenatally.     

Selective Angiography in the Diagnosis of Hydatid Disease of the Liver

Six cases of cystic hydatid disease of the liver studied by selective angiography are described. In three of these a very characteristic triad of signs was demonstrated. In the fourth case, where the cysts were relatively small and restricted to the left lobe of the liver, no angiographic abnormality and could be found although the diagnosis was strongly suspected clinically. In the fifth case, where the cyst had virtually extruded itself from the liver and had undergone chronic leakage, the findings were atypical. The sixth patient had an old heavily calcified, non-symptomatic cyst, and here the angiographic findings were unremarkable. We believe that these cases illustrate the great value of selective angiography in this condition and some of its limitations.     

Mass occurrence of multilamellar bodies in myopathy

In a case of atypical myopathy submicroscopic examinations revealed intact ground structure and large number of solitaer, regular multilamellar bodies. The author suggests, in accordance with literary data, this typical alteration to be due to the applied short term Chloroquine treatment.     

Exponential decay characteristics of the stochastic integer multiple neural firing patterns

Integer multiple neural firing patterns exhibit multi-peaks in inter-spike interval (ISI) histogram (ISIH) and exponential decay in amplitude of peaks, which results from their stochastic mechanisms. But in previous experimental observation that the decay in ISIH frequently shows obvious bias from exponential law. This paper studied three typical cases of the decay, by transforming ISI series of the firing to discrete binary chain and calculating the probabilities or frequencies of symbols over the whole chain. The first case is the exponential decay without bias. An example of this case was discovered on hippocampal CA1 pyramidal neuron stimulated by external signal. Probability calculation shows that this decay without bias results from a stochastic renewal process, in which the successive spikes are independent. The second case is the exponential decay with a higher first peak, while the third case is that with a lower first peak. An example of the second case was discovered in experiment on a neural pacemaker. Simulation and calculation of the second and third cases indicate that the dependency in successive spikes of the firing leads to the bias seen in decay of ISIH peaks. The quantitative expression of the decay slope of three cases of firing patterns, as well as the excitatory effect in the second case of firing pattern and the inhibitory effect in the third case of firing pattern are identified. The results clearly reveal the mechanism of the exponential decay in ISIH peaks of a number of important neural firing patterns and provide new understanding for typical bias from the exponential decay law.     

Fundamental Studies on the Aerobic Fermentation

The oxygen uptake rate of aggregated mycelia is decreased to an extent which, in the case of a typical spherical aggregate, could be estimated depending on its diameter, mycelial density, oxygen diffusivity, and so forth. Equations were presented in this paper to evaluate the oxygen uptake rate of an mold pellet. A favorable agreement was found between the calculation and the experiment.     

Functionality Versus “Typical Product” Measures of Technological Progress

Technological progress and adoption are fundamentally interconnected with environmental challenges faced by society. At the product level, researchers often explore the interplay between technological change and the environment by tracking trends in impacts per unit functionality—for example, gasoline consumed per distance traveled by a vehicle. In this article, we explore an alternative measure: “typical product.” A typical product measure accounts for changes in consumers’ demand and use of products as product quality improves—for example, gasoline consumed for a typical driving pattern for a vehicle. We compare and contrast functionality and typical product measures through a case study of electricity use to fabricate Intel desktop microprocessors from 1995 to 2006. The functionality normalization is measured in terms of electricity use per transistor produced. Results show rapid and sustained exponential decrease. The “typical product” measures electricity use per typical desktop microprocessor of a given year (e.g., a Pentium II in 1998, a Pentium IV in 2002). Results show that, despite fluctuations, energy use per typical microprocessor is roughly constant over the 12‐year period. The explanation of this result is that although technological progress dramatically reduces the energy needed per transistor, it also induces demand for more powerful chips, which contain many more transistors. The typical product measure has applications in defining functional units in life cycle assessment, characterizing rebound effects, and measuring energy efficiency trends.     

Strawberry hemangioma of infancy: early definitive treatment with an argon laser.

This report documents the successful treatment of a hemangioma (strawberry hemangioma) at 5 weeks of age with the argon laser. The natural course of strawberry hemangioma of infancy is well known. It begins as a very small spot and develops very rapidly within the first few weeks of life. Many grow to a very large size and produce significant morbidity. It is logical to assume that if these were ablated early, the life cycle could be aborted. The patient of this case study developed two spots that appeared to be typical evolving hemangiomas. One was treated and disappeared. The other was not treated and evolved into a typical strawberry hemangioma that eventually involuted. This would indicate that early treatment holds some promise.     

Characteristics of the human EEG during cognitive-mnemenic activity under hypoxic conditions

The amplitude-frequency and spatiotemporal characteristics of the EEGs of subjects performing various cognitive-mnemenic activities under the conditions of graduated hypoxia were studied. The quickness and correctness of test performance were significantly decreased beginning from the sixth minute of hypoxia as compared to normoxic conditions. The amplitude and mean period of the dominant EEG activity in this functional state were higher than in the same tests performed under normoxic conditions and lower than in the case of hypoxia not accompanied by the performance of tests. The spatiotemporal characteristics of the EEG under hypoxic conditions displayed both the characteristics typical of hypoxia (a decrease in EEG cross-correlation within anterior cortical regions) and those typical of cognitive-mnemenic activity (an increase in the correlation between the EEGs of distant zones of anterior and posterior cortical regions). It is assumed that the “intermediate” EEG pattern observed in subjects performing cognitive-mnemenic tests under hypoxic conditions reflects opposite effects of hypoxia and intellectual effort on the functional activity of brain neurons.     

A case of membranous lipodystrophy complicated by Fanconi's syndrome

A case of membranous lipodystrophy complicated by Fanconi's syndrome is described. A 40-year old man complaining of pain in his legs was admitted to our hospital. Roentgenograms showed cystic changes in the long bones. Biopsy of the affected lesion of the femur revealed a peculiar membranocystic structure in the marrow that is typical of membranous lipodystrophy. He had a neuropsychiatric disorder which is often associated with this disease. Laboratory studies were remarkable for renal proximal tubular dysfunction., i.e., Fanconi's syndrome. Membranous lipodystrophy is a rare, hereditary disease that has been reported mainly from Japan and Finland. This is the first case of this disease complicated by Fanconi's syndrome. The possible relationship between these disorders is discussed.     

Immunochemical study of serum in the diagnosis of mu-chain disease]

An abnormal protein revealed in the serum of a patient with an unknown lymphoproliferative disorder proved to be micron-paraprotein: micron-heavy chain complexes of various molecular weight totally lacking light chains. The results of immunochemical analysis of this case are compared with the published data on micron-chain disease. The following immunochemical features typical for micron-chain disease were observed in this patient: anodal mobility of paraprotein, failure to reveal it by serum electrophoresis, that is, absence of M-gradient, and presence of Bence Jones protein, type x in the urine and the serum. The peculiarity of the case consists in a high tendency of free x-chains to form complexes, and therefore in their marked electrophoretic heterogeneity giving a false impresssion of the ability of micron-paraprotein to react with the anti-x serum, thus complicating the diagnosis. Possible causes of a defect in the IgM assembly are discussed.

Plasma cell granuloma of the tongue. Report of a case

A case of plasma cell granuloma of the tongue in an otherwise symptomless 48-year-old caucasian female is reported. The polyclonal nature of the plasmocytes was revealed by immunostaining of kappa and lambda light chains. Electron microscopic observations showed typical mature plasmocytes. A parasitic etiology of this type of lesion is suggested.     

Cytological and molecular changes in the atypical case of accelerated human aging

A complex research of cells of a patient with unusual form of premature ageing was made. The clinical picture is not typical for any of known forms of hereditary premature aging--progerias. Skin fibroblasts of the patient AG has limited proliferation capacity in vitro. It was shown by fluorescent-immunochemical hybridization (FISH-method), that the level of stable chromosome aberrations in AG blood lymphocytes was characteristic of aged 55-65 years, though as he was only 26 years old. Some characteristic peculiarities, typical for progerias, were found in the reaction of skin fibroblasts of AG to growth factors addition. Some clinical and biochemical peculiarities are results rather, than reasons of the disease. The conclusion is that the premature ageing in this case is a manifestation of Werner's syndrome--one of hereditary forms of accelerated senescence.
