Six months after an attack of pyelonephritis, adnexitis and candida colpitis an 18-year-old girl developed some clouding of consciousness. On neurological examination she showed organic behavioural changes, discrete anisocoria and possible meningism. Computed tomography revealed hydrocephalus and signs of increased cerebrospinal fluid (CSF) pressure. CSF contained 2336/3 cells, while total protein was raised to 7.0 g/l and lactate concentration to 6.85 mmol/l. Glucose concentration in CSF was 51 mg/dl and 75 mg/dl in serum. As tuberculous meningitis was suspected, treatment was started with four tuberculostatic drugs, but there was no improvement. Five weeks later microscopic CSF examination showed fungal spores and nonbranching hyphae. The maximal candida haemagglutination titre in CSF was 1:2048. CSF culture grew Candida albicans. The further course was complicated by side effects to the antimycotic drugs (amphotericin B between 4.5 and 45 mg daily; flucytosine 1.7 g four times daily) and recurrent obstruction in the ventricular system requiring repeated neurosurgical interventions. However, full cure was achieved after seven months' hospital treatment.

The authors present the case of a 3-year-old girl with a history of myelomeningocele repair, ventriculoperitoneal (VP) shunt placement for hydrocephalus, and shaken baby syndrome who presented in a hypernatremic state as a result of dehydration. At the time of presentation, the patient had experienced a 1-week-long history of diarrhea associated with antibiotic agents used to treat a coexisting pyelonephritis. On admission, the patient exhibited signs and symptoms of dehydration and was discovered to have profound hypernatremia with a serum sodium level of 180 mmol/L. A computerized tomography (CT) scan of the head revealed ventricular enlargement compared with previous imaging findings. A shunt tap revealed intracranial hypotension with good proximal flow. The child was treated for her hypernatremic state, and her neurological condition returned to baseline level. Subsequent CT scans of the head demonstrated a return of the ventricular system to its premorbid size. On the basis of the initial radiographic presentation and subsequent evaluation, the authors hypothesize that the ventricular enlargement was a result of hypernatremia. The signs and symptoms were similar to those found in patients with a VP shunt obstruction; however, a shunt tap revealed intracranial hypotension and excellent proximal flow. To the authors' knowledge, there has not been a radiographically documented case of reversible ventricular enlargement associated with hypernatremia.

Spontaneous or nosocomial Escherichia coli meningitis remains rare in healthy adults but is still carrying a high mortality rate despite adapted antimicrobial treatment for susceptible strains. A 39-year-old woman was admitted to the hospital with severe subarachnoid haemorrhage complicated by acute hydrocephalus. On hospital day 10, she developed Streptococcus anginosus septicaemia and urinary tract infection due to a multisensitive strain of E. coli. This infection was successfully controlled by antimicrobial therapy. As a late complication in the neurosurgical ward (day 39), she developed fever, alteration of consciousness, and shock, leading to the diagnosis of bacterial meningitis. The culture of blood, cerebrospinal fluid, and urine grew positive for a multisensitive E. coli. The strain was identified as O117:K52:H, a serotype that was until now never associated with acute meningitis or brain abscesses. The source appeared to be the urinary tract with the demonstration of acute pyelonephritis. The patient died on day 94 from delayed complications of multiple brain abscesses.

Ralstonia species are Gram-negative bacilli that have increasingly been recognized as emerging nosocomial pathogens, particularly in immunocompromised hosts. Ralstonia pickettii is the most clinically important pathogen from the Ralstonia genus. Nosocomial outbreaks of Ralstonia pickettii infections brought about by the use of contaminated medical solutions, including saline, sterile water, as well as disinfectants, have been reported. There have been case reports of invasive infections with variable presentations. Here, we describe three cases of Ralstonia pickettii bacteremia during a period of one year in a tertiary care hospital in Karachi, Pakistan. The first case was a 76-year-old male, known case of type 2 diabetes mellitus (DM), hypertension, and amyotrophic lateral sclerosis, who presented with complaints of burning micturition, hematuria, and fever. The patient had a history of multiple hospital admissions in the recent past. His blood culture was found to be positive for Ralstonia pickettii. A computed tomography scan of the kidneys, ureter, and bladder (CT KUB) was suggestive of pyelonephritis. The patient improved on intravenous meropenem. The second case was a 47-year-old man, who was admitted with a gunshot injury to the neck, resulting in complete cervical cord resection and mild hydrocephalus with intraventricular hemorrhage. The patient had a prolonged intensive care unit (ICU) stay, which was complicated by ventilator-associated pneumonia with Acinetobacter and central line-associated bloodstream infection (CLABSI) with Ralstonia pickettii. He was treated with meropenem and colistin but continued to deteriorate and expired. The third case was a 46-year-old lady, known case of end-stage renal disease (ESRD), who was admitted with prosthetic valve endocarditis. She had a prolonged hospital stay complicated by CLABSI with Ralstonia pickettii, improved on meropenem, but later died due to fungemia. Ralstonia pickettii is an emerging cause of nosocomial infection in patients, particularly those with a prolonged hospital stay, and can cause invasive and severe infections.
