Cryptococcal meningitis is the major life threatening opportunistic infection and is caused by Cryptococcus neoformans. Severe headache and with or without fever is the characteristic feature in patients with cryptococcal meningitis. Headache is seen in > 75% while Fever is seen in only 65% of the patients. For the diagnosis of cryptococcal infection neuroimaging of the brain, India ink, cerebrospinal fluid (CSF) culture is considered. We report a case of cryptococcal meningitis who’s cryptococcal antigen testing was positive and India ink examination showed the cells resembling cryptococcus and he was treated with antifungal drugs mainly the combination therapy showed better outcome. Key words: Cryptococcal meningitis, Amphotericin B, Cerebrospinal fluid (CSF).

Two cases of hemorrhagic meningoencephalitis secondary to Naegleria fowleri infection confirmed by postmortem analysis are described. The first patient is a 5-year-old boy who presented with a severe headache, neck stiffness, and lethargy. His neurologic examination was significant for somnolence and nuchal rigidity. Cerebrospinal fluid studies and structural neuroimaging were consistent with hemorrhagic meningoencephalitis. Another 5-year-old boy presented to a different institution 2 miles away in the same week with similar complaints. Both patients declined rapidly and expired within 48 hours of admission secondary to transtentorial herniation caused by the mass effect of inflammation, edema, and hemorrhage with displacement of the brain stem. Histopathologic and immunochemistry analysis of brain tissue revealed the presence of Naegleria trophozoites in both cases.

Cryptococcus neoformans detection was optimized using PCR technique with the objective of application in the clinical laboratory diagnosis. The amplification area was ITS and 5,6S which encodes the ribosomal RNA (rRNA). A total of 72 cerebrospinal fluid (CSF) samples were used, obtained from cases with and without AIDS. The patients had cryptococcal meningitis (n = 56) and meningitis caused by other agents (n = 16). The results demonstrated that PCR test had the highest sensitivity rates, superior to culture (85.7%) and to India ink test (76.8%). PCR was found to be sensitive in detecting 1 cell/mL and highly specific since it did not amplify other fungal DNA. The comparative analysis of the methods showed that PCR is more sensitive and specific and is applicable as an important laboratorial resource for neurocryptococcosis diagnosis.

A patient was admitted complaining of fever and headache. He was suspected of meningitis due to nuchal rigidity, and a lumbar puncture was performed. The patient was diagnosed as having cryptococcal meningitis, as Cryptococcus neoformans was found in an India ink preparation of the cerebrospinal fluid. Both amphotericin B and low-dose flucytosine (50 mg/kg/d) were concomitantly administered to the patient and his clinical symptoms improved. However, the combination therapy induced granulocytopenia and thrombocytopenia, which resolved after discontinuance of the drugs. Amphotericin B alone failed to cause granulocytopenia or thrombocytopenia. These results suggest that the mechanisms of granulocytopenia and thrombocytopenia may be toxic reactions to flucytosine in the azotemic state caused by amphotericin B. Our report emphasizes the need for clinicians to monitor for granulocytopenia and thrombocytopenia in patients receiving treatment with both amphotericin B and flucytosine, even when flucytosine is administered in a low dose.

Background. Cryptococcus is an opportunistic fungal pathogen that leads to life-threatening infections. Cryptococcal infections are mainly reported in HIV patients and less commonly encountered in non-HIV immunocompromised host. Cryptococcus neoformans (C. neoformans) is the most common Cryptococcus species causing diseases in humans which can be presented as pulmonary, meningitis, cutaneous, and/or disseminated cryptococcosis. Case Presentation. A 12-year-old female girl from Cairo, Egypt, presented to the pediatric hospital with signs of systemic lupus erythematosus (SLE). She had an aggressive lupus nephritis course for which corticosteroids, mycophenolate mofetil, and cyclophosphamide were prescribed, and the child gradually improved and was discharged. Two months later, the patient exhibited skin lesions involved both in her legs, massive ulcers were developed and extended rapidly through the entire legs followed by deterioration in her conscious level, and signs of meningitis were documented. Cerebrospinal fluid (CSF) examination and microbiological workup were confirmatory for C. neoformans infection, and mental and motor functions were rapidly deteriorated. Treatment with amphotericin B in addition to supportive treatment and close follow-up of the patient’s medical condition result in obvious clinical improvement and patient discharge with minimal residual weakness in her legs after almost a one-month duration. After six months, the patient was brought to the emergency department complaining of repeated attacks of seizures, a lumbar puncture was performed, and culture results were again confirmatory for C. neoformans. An intensive course of antifungal therapy was prescribed which was successful, evident by resolution of the signs and symptoms of infection in addition to negative culture results and negative sepsis biomarkers. The child clinically improved, but unfortunately, gradual optic nerve degeneration and brain cell atrophy as a sequel of severe and longstanding cryptococcal infection resulted in her death after almost one year from her first attack. Conclusion. Cryptococcal infection among non-HIV patients is a rare disease but can result in advanced medical complications which may be fatal. The disease should be suspected to be reliably diagnosed. Cryptococcus infection can be presented as a skin lesion which, if not treated properly at an earlier time, can result in dissemination and life-threatening consequences. Amphotericin B can be used effectively in cryptococcosis management in the settings where flucytosine is not available. Signs of cryptococcal meningitis can be manifested again after a period of remission and clinical cure which signifies the latency of Cryptococcus in the central nervous system. The second activation of Cryptococcus after its latency is usually life-threatening and mostly fatal.

Abstract Hydrocephalus is a group of life threatening disorders of cerebrospinal fluid flow in and around the brain. It is characterized, in most cases, by accumulation of cerebrospinal fluid in the ventricles of the brain and a progressive increase in pressure in the cranium. The etiology has traditionally been ascribed to an imbalance between the formation and absorption of the cerebrospinal fluid (CSF). Based on this understanding, the treatment is to insert a shunt surgically in order to drain the accumulating fluid in the heart or abdomen. This treatment is invasive and has a high failure rate.

Migraine is a chronic paroxysmal neurological disease characterized by attacks of moderate or severe headache accompanied by reversible neurologic and systemic symptoms. Although not life threatening, migraine can cause disability in the productive population. Migraine sufferers generally have a family history of migraine so that migraine is considered a genetic disease. Endogenous psychological factors such as stress or fatigue are the main triggers for migraine. Migraine pathophysiology involves various parts of the brain so that migraine symptoms are complex. Management of acute migraine can be done pharmacologically and non-pharmacologically. Migraine preventive management is needed if the patient has a chronic migraine or does not respond to abortive treatment.

Cerebrospinal fluid (CSF) from eight patients with cryptococcal meningitis, from ten patients with viral meningitis, and from four control patients without meningitis were analyzed by electron-capture gas-liquid chromatography (EC-GLC). All cryptococcal specimens had similar EC-GLC profiles, and these differed from those of the controls. Viral EC-GLC patterns were different from those obtained with specimens from the patients with cryptococcal infection and from the controls. In addition, specimens from patients with various types of viral infections gave profiles that differed from each other. Two normal CSFs were inoculated with Cryptococcus neoformans; aliquots of these cultures showed an EC-GLC pattern very similar to that seen in CSF of patients with cryptococcal meningitis. The EC-GLC procedure is rapid, reproducible, and easy to perform and may hold promise as an additional aid in the diagnosis of cryptococcal infection.

The increase of intracranial pressure is a life-threatening condition which requires urgent treatment to prevent the further neurologic problem. A design of the brain port is proposed, in which a bi-directional check valve controls the flow of the cerebrospinal fluid depending on the intracranial pressure in accordance with the other devices. Drug administration and cerebrospinal fluid drainage could be performed easily without any additional surgery other than the transplant of a brain port. The intracranial pressure value at which the cerebrospinal fluid should be drained is adjustable by altering the pressure of the drainage bag. The results of the experiment with the simulated brain system are supporting and verifying the substance of this article.

The syndrome of transient headache and neurologic deficits associated with cerebrospinal fluid lymphocytosis (HaNDL) is a benign and self limiting disorder characterized by 1 or more episodes of severe headache and transient neurologic deficits with lymphocytic pleocytosis in the cerebrospinal fluid. We report a case of a 30-year-old male who presented with four episodes of headache followed by hemi paresis and hemisensory loss in a week the patient was completely asymptomatic in between each episode of headache with neurological deficits. Persistent serial imaging to visualize the brain were normal with evidence of cerebrospinal fluid lymphocytosis, which lead to the diagnosis of HaNDL. We need to advocate a high degree of suspicion for HaNDL in the background of strong clinical history and findings, when imaging is normal.

Abstract Background Cryptococcal meningitis (CM) has a high morbidity and mortality due to the low detection of Cryptococcus in cerebrospinal fluid (CSF) during the early stage of the disease with traditional methods. Case presentation In addition to the traditional methods of India ink staining and cryptococcal antigen (CrAg), we used nanopore sequencing and next-generation sequencing (NGS) to detect pathogenic DNA in CSF samples of three patients with CM. The CSF samples of all three patients were positive by India ink staining and CrAg. NGS also detected Cryptococcus in all three CSF samples. Nanopore sequencing detected Cryptococcus in two CSF samples. Conclusion Nanopore sequencing may be useful in assisting with the clinical diagnosis of CM. Further research is needed to determine the sensitivity and specificity of nanopore sequencing of CSF.
