Combined treatment with ceftriaxone and linezolid of pneumococcal meningitis: a case series including penicillin-resistant strains.

This study evaluated the role of linezolid in the treatment of patients suffering from pneumococcal meningitis. Treatment included ceftriaxone (4000 mg every 24 h), linezolid (600 mg every 12 h) and dexamethasone (8 mg every 6 h). Linezolid was withdrawn if a penicillin-susceptible isolate of Streptococcus pneumoniae was identified. Of 16 patients studied, seven were infected with penicillin-non-susceptible isolates of S. pneumoniae, two died, and three reported sequelae. No toxicity was reported. It was concluded that linezolid can be used for the treatment of pneumococcal meningitis, as an alternative to vancomycin or rifampicin, in regimens including a third-generation cephalosporin.

Pulmonary aspergillosis with possible cerebral involvement in a previously healthy pregnant woman.

UNLABELLED: Invasive aspergillosis is observed mainly in immunodepressed patients. Here we report a case of pulmonary aspergillosis with CNS involvement in a pregnant woman without other known causes of immunodeficiency. CASE REPORT: A 23-years old pregnant woman underwent a caesarean because of unexplained seizures. During the subsequent days worsening headache and a deteriorating neurological status were reported suggesting meningitis. Stiffness, right sided hemiparesis and cranial nerve palsies were observed at admission. Radiological findings revealed lesions involving the right pulmonary apex, the right cerebellar hemisphere and the Pterygopalatina fossa. Microbiological studies revealed large colonies of Aspergillus fumigatus. A favorable outcome was observed after administration of liposomal amphotericin B and 5-fluorocytosine and, at improved conditions, when oral uptake of itraconazole was given. The authors conclude that risk of infections sustained by fungal opportunistic agents during pregnancy must be considered. Sequential antifungal administration may be an efficient therapy able to shorten hospitalization.

[Tuberculous meningitis in childhood: review of cases observed in the years 1995-1999].

UNLABELLED: In this study we reviewed M. tuberculosis meningitis (TBM) cases in childhood at our unit in a five-year period. METHODS: Included in this retrospective study were children admitted to Cotugno Hospital from 1995 to 1999 who fulfilled criteria for a TBM diagnosis. Medical records were analyzed for epidemiological data, clinical manifestations, laboratory test results, radiological investigations and clinical outcome. RESULTS: We identified 10 children with TBM. Family history of tuberculosis (TB) was observed in 6 patients. Fever preceded hospital admission of 4-60 days (median 8 days); neurological signs were present 1-6 days before admission in 8 patients. All patients showed a predominance of lymphocytes, elevated proteins and reduced glucose concentration in cerebrospinal fluid (CSF). Mycobacterium tuberculosis was either cultured or identified by acid fast stain in 5 patients. Cranial CT-scans and MRI showed hydrocephalus in 8 patients and ring-enhancing lesions in 6. Antituberculous therapy was administered according to current recommendations for at least 12 months, with a 4-6 week steroid therapy course. Two patients had permanent neurological sequelae. CONCLUSIONS: Careful evaluation of symptoms and CSF findings is the only way to establish an early diagnosis and reduce sequelae.

[Hepatic encephalopathy. Pathogenesis and therapy].

Hepatic encephalopathy is a frequent complication of cirrhosis. Portal-systemic shunts and depression of hepatic function are the primary underlying abnormalities. Arterial blood ammonia levels are frequently elevated during hepatic encephalopathy and are lower when a clinical improvement is established. Glutamine synthesis is part of the metabolic pathway for ammonia cerebral detoxification that induces ATP and glutamate (excitatory neurotransmitter) depletion. Plasma levels of branched chain amino acids are reduced in patients with cirrhosis, this event allows aromatic amino acids to cross the hemato-liquoral barrier through exchange with glutamine. Cerebral excess of aromatic amino acids promotes the synthesis of octopamine and feniletiletanolamine, weak neurotransmitters. Benzodiazepine-like substances may affect GABA-ergic transmission by interacting with their receptors on the GABA-benzodiazepine complex. Therapy is aimed at controlling the events that may precipitate the acute encephalopathy, at reducing the ammonia levels, and correcting the neurotransmission abnormalities.

[Acute and chronic viral hepatitis in HIV positive patients].

In this study we evaluated the spreading of HBV, HCV, HDV and HIV among drug user patients. Spreading of hepatotropic viruses resulted high (HBV 84%, HCV 87%, HDV 7%), while spreading of HIV resulted relatively low (18%). During the period considered we did not observe any favourable effect of hepatotropic viruses on the progression of HIV infection, while the chronic evolution of acute viral hepatitis HBV related was high (90%) in HIV+ patients. HIV infection did not determine different histological findings in respect to HIV- patients with chronic hepatitis, HBV or HCV related

Typhoid fever in the Neapolitan area: a case-control study.

Typhoid fever is endemic in the Neapolitan area, where its yearly incidence rate largely exceeds the corresponding national figure. During the period from January to June, 1990, a matched case-control study was carried out in order to identify risk factors of the disease in this area; 51 subjects (mean age 27.2 years) with typhoid fever were compared with 102 controls matched with respect to age, sex and educational level. Consumption of raw shellfish was reported by 76.5% of the cases, as opposed to 19.6% of the controls (P < 0.01). Subjects who had eaten this food item had a 13.3-fold risk (C.I. 95% = 5.5 - 32.8) of contracting typhoid fever. In contrast, no risk was found to be associated with consumption of cooked shellfish, raw vegetables, ice-cream, non-potable water, or unpasteurized milk. The risk factor identified in this study shows that hazardous dietary habits and inadequate sewage treatment facilities, combined with lack of sanitation in the harvesting and marketing of shellfish, play a major role in the endemicity of typhoid fever in the Neapolitan area.

Factors influencing the presentation and outcome of tuberculous meningitis in childhood.

UNLABELLED: Tuberculosis (TB) is an important cause of morbidity and mortality worldwide. Here, we describe our experience of childhood tuberculous meningitis (TBM), focusing on factors influencing presentation and outcome. PATIENTS AND METHODS: Children aged 0-14 years, with diagnosis of TBM and 24 months of post-therapy follow-up, were evaluated in this retrospective study. RESULTS: Thirty-two patients with TBM were identified. Fever, nuchal rigidity and vomiting were the main presenting symptoms. Fourteen cases (44%) presented with cranial nerve palsy. Seventeen (53%) patients were in advanced stage of the disease on admission. Cerebrospinal fluid (CSF) examinations showed low glucose, high proteins and pleocytosis. A central nervous system device was placed in 4 cases (13%) because of worsening hydrocephalus. Four (13%) patients died, while 6 (19%) had sequelae. Faster normalization of CSF parameters was associated with better outcome. CONCLUSION: Early antimycobacterial therapy and close monitoring of TBM in childhood improve the outcome.
