چکیده

INTRODUCTION The postmortem observations of Green, published in the Lancet in 1836, were the fi rst to describe the distinct pathological features of tuberculous meningitis and set it apart from the other recognised causes of ‘acute hydrocephalus’ (Green 1836). The challenge for the physician then lay in distinguishing the disease before death, and delivering the grave prognosis. Thomas Mann captures the full horror of this process in Dr Faustus as the helpless Dr Kurbis presides over the agonizing death of a small child from tuberculous meningitis: The whole thing lasted scarcely two weeks, including the earliest signs that all was not quite well with the child; from the beginnings no one – I believe no one at all – even dreamed of the horror to come ... Kurbis tested the child’s eyes, the pupils of which were tiny and showed a tendency to squint. The pulse raced. Muscular contractions developed, and an incipient rigidity of the neck. It was cerebrospinal meningitis, infl ammation of the meninges. The good man pronounced the name with a deprecating movement of the head shoulderwards, probably in the hope that they might not know the almost complete powerlessness of medical science in the face of this onslaught. Tuberculous meningitis was invariably fatal before the advent of anti-tuberculosis chemotherapy. Therefore, the need to diagnose the disorder became a priority after streptomycin was found to reduce mortality of tuberculous meningitis by one third in 1948 (MRC 1948). Progress was rapid over the next 5 years: adding para-aminosalicylic acid to streptomycin reduced mortality to 30%, and the addition of isoniazid to both of these compounds lowered the mortality still more to Robert Koch: photograph taken in the 1880s, around the time of his discovery of the tubercle bacillus (or ‘bacille Koch’, as it is still called in Vietnam).

Fractional Probability Measure and Its Properties

Based on recent studies by Guy Jumarie [1] which defines probability density of fractional order and fractional moments by using fractional calculus (fractional derivatives and fractional integration), this study expands the concept of probability density of fractional order by defining the fractional probability measure, which leads to a fractional probability theory parallel to the classical ...

A Protocol for Diagnosis and Management of Cerebrospinal Shunt Infections and other Infectious Conditions in Neurosurgical Practice

Infections of the cerebrospinal shunts and other neurosurgical structures are not uncommon in the clinical practice. These infections are mostly clinical emergencies carrying negative prognostic impacts on the patients as well as spending healthcare resources. The low pathogenicity nature of some implicated pathogens results in minimal physical signs that may complicate the diagnosis and mislea...

O 16: Challenge in Diagnosis and Management of Autoimmune Encephalitis

The first description of an autoimmune encephalitis dates back to 1888, when Hermann Oppenheim described a patient with neurological symptoms but no underlying brain pathology. The field of autoimmune encephalitides associated with antibodies targeting cell-surface antigens is rapidly expanding and new antibodies are discovered frequently. Autoimmune encephalitis is a difficult clinical diagnos...

Serum Free Light-chain Assay for the Diagnosis, Management, and Prognosis of Multiple Myeloma

In recent decades, new serum biomarkers have been developed for routine laboratory practice, such as assaying serum free light chains and more recently, assaying immunoglobulin heavy and light chain isotypes (Hevylite). In this work, we highlight the interest of new biomarkers (Hevylite Test) in the management of monoclonal gammopathies because of the technical advantages it confers and the se...

Diagnosis and management of hypoglycaemia due to pancreatic insulin-secreting neoplasia in a German shepherd dog

A 7-year-old castrated male German shepherd dog was presented with a 10-day history of intermittent lethargy, weakness and episodic seizures. Laboratory findings after admission revealed hypoglycaemia and hyperinsulinaemia. Provisional diagnosis of insulinoma was made based on the presence of concurrent hypoglycaemia and elevated insulin level. In exploratory laparotomy a small nodular mass was...
