In September 2008, the Austrian Agency for Health and Food Safety (AGES) learned of an outbreak of diarrheal illness that included a 71-year-old patient hospitalized for gastroenteritis with a blood culture positive for Listeria monocytogenes. Three stool specimens provided by seven of 19 persons attending a day trip to a foreign city, including a final break at an Austrian tavern, yielded L. monocytogenes. All isolates were of serovar 4b and had fingerprints indistinguishable from each other. A cohort study revealed that the outbreak of gastroenteritis occurred among 16 persons who had eaten dinner at the wine tavern on September 6. Of the 15 persons who ate from platters of mixed cold-cuts, 12 (80%) developed symptoms of febrile gastroenteritis within 24-48 h. The median age of those who became ill was 62 years. A 72-year-old patient recovered from gastroenteritis but was hospitalized with bacterial meningitis on day 19 after the dinner. The epidemiological investigation identified the consumption of mixed cold-cuts (including jellied pork) at the wine tavern as the most likely vehicle of the foodborne outbreak (P = 0.0015). This hypothesis was confirmed by microbiological investigation of jellied pork produced by the tavern owner on September 3. L. monocytogenes was isolated from leftover food in numbers of 3 x 10(3)-3 x 10(4) colony forming units/g and was indistinguishable from the clinical outbreak isolates. Symptoms reported by the 12 patients included unspecified fever (12x), diarrhea (9x), headache (5x), vomiting (4x), body aches (2x) and sore throat (1x). Active case finding identified one case of rhombencephalitis (female, age 48) among another group of four guests, among whom only the patient and her asymptomatic husband had eaten jellied pork on September 6. This is the first outbreak of L. monocytogenes-associated gastroenteritis reported in Austria. The occurrence of a secondary case of meningitis (diagnosed on day 19 after consumption of jellied pork) indicates a significant risk of systemic listeriosis among elderly patients with febrile gastroenteritis caused by L. monocytogenes; antibiotic therapy should therefore be considered in such cases of documented listerial gastroenteritis.

Pseudomonas stutzeri which is an aerobic, non-fermentative gram-negative bacillus frequently found in soil, water and hospital environment, rarely leads to serious community-acquired infections. In this report a case of community-acquired meningitis due to P. stutzeri was presented. A 73-years-old male patient was admitted to the emergency department with the complaints of nausea, vomiting, headache, dizziness, difficulties in walking and speaking and loss of consciousness. There was no history of an underlying disease or immunosuppression. Physical examination revealed nuchal rigidity, however, Kernig and Brudzinski signs were negative. The cerebrospinal fluid (CSF) analysis revealed 0.4 mg/dl glucose (simultaneous blood glucose 145 mg/dl), and 618 mg/dl protein and 640 leucocyte/mm3 (90% PMNL). No bacteria were detected in Gram stained and Ehrlich-Ziehl-Neelsen stained CSF smears. Upon the diagnosis of acute bacterial meningitis, treatment with ceftriaxone and ampicillin was initiated, however, the patient died after 16 hours of hospitalization. CSF culture yielded the growth of gram-negative oxidase-positive bacteria and the isolate was identified as P. stutzeri by Vitek-2 Compact system (bioMerieux, France). The isolate was found to be sensitive to piperacillin/tazobactam, amikacin, gentamycin, ceftazidime, cefepime, ciprofloxacin, imipenem and meropenem. Since the patient was lost due to acute respiratory and cardiac failure, it was not possible to change the therapy to agent specific therapy. In conclusion, it should always be kept in mind that uncommon agents could lead to community-acquired meningitis in elderly patients and empirical treatment protocols might fail in such cases resulting in high morbidity and mortality.

Bacterial meningitis is a medical emergency requiring prompt recognition and evaluation and urgent initiation of appropriate antibacterial therapy. However, early recognition of severe bacterial infection including bacterial meningitis is a challenge in infants. Two clinical forms are basically observed in infants and young children: firstly, clinical meningitis which is characterized by fever, usually greater than 39 degrees C, and poorly specific gastrointestinal signs such as refusal of feeding and/or vomiting; irritability, abnormal crying, bulging fontanel, unusual generalized seizures occurring before six months of age and lasting more than 10 min should draw the clinician's attention and lead him/her to perform a lumbar puncture and initiate antibiotics; secondly, severe sepsis which is characterized by tachycardia, cold and/or mottled limbs and sometimes leg pain which should suggest a meningococcal disease; it is quite urgent to administer rapid fluid loading and antibiotic treatment while postponing lumbar puncture before the septic cascade evolves towards septic shock, extensive hemorrhagic rash, and ischemic limbs. Given the relative frequency of viral self-limiting diseases and rarity of serious bacterial infections, guidelines were published to guide the clinician's decision when dealing with a febrile infant. However, an alternative to these guidelines was recently suggested with a more clinically oriented decision-making attitude appearing as efficient while limiting hospitalizations.

Childhood meningitis is still a major cause of neurological disabilities and death, which can be reduced by early initiation of treatment. This study was done with an objective to diagnose childhood meningitis earlier based on clinical characteristics and early obtainable cerebrospinal fluid (CSF) indices, which help to start early empiric treatment and prevent worse prognosis. The study was conducted during the period of January to December; 2003. One hundred suspected cases of childhood meningitis aged 1 month to 12 years admitted into the Department of Paediatrics, Dhaka Medical College Hospital, Dhaka, Bangladesh were selected for the study. It was a prospective study and sampling was purposive. Diagnosis was made by history, clinical examination, complete blood count and CSF study. Early treatment was started. Number of deaths was noted and neurological outcome was assessed in children who survived by clinical examination at the time of discharge. Study results showed 64% bacterial, 20% tuberculous and 6% viral meningitis. Fever (100%), altered consciousness (100%) were the most common features in all type of meningitis. Other predominant features were convulsion (90%), bulged fontanel (68%), reluctant to feed (67.18%), neck rigidity (67%) and vomiting(43.75%) in bacterial meningitis, convulsion (75%), neck rigidity (65%), vomiting (40%) and focal neurological signs (35%) in tuberculous meningitis, reluctant to feed (100%), convulsion (83.3%), neck rigidity (83.3%) and vomiting (66.6%) in viral meningitis. In all cases of meningitis CSF total leukocyte count was >5/mm3. Regarding immediate outcome in bacterial meningitis 48.8% improved without neurological sequelae, 43.7% patient developed neurological sequelae and 4.6% patient died. In tuberculous group, only 30% improved without neurological sequelae, 40% developed neurological sequelae and 20% patient died. In viral meningitis 83.3% improved without neurological sequelae. Duration of the main complaint specially fever at the time of presentation, level of consciousness, convulsion were the most important predictor of out come in childhood meningitis.

Clinical diagnosis of acute bacterial meningitis may be delayed, either because off lack of sensitivity of clinical signs, or because of a poor vital prognosis; but over diagnosing is also frequent, leading to useless, expensive, and potentially dangerous hospitalizations. We conducted a comprehensive review of English and French literature from 1997 to 2007 by searching MEDLINE to review the accuracy of clinical examination for the diagnosis of meningitis. Additional references were identified by reviewing reference lists of articles back to 1993. We used the keywords "meningitis", "meningitis and clinical features", "cerebrospinal fluid (CSF) pleocytosis", "headache and fever", "Kernig sign", "Brudzinski sign", and "neck stiffness". We excluded nosocomial meningitis. Sensitivity for clinical signs such as headache, vomiting, or fever was low, generally less than 30%, neck stiffness could reach 45%, but the absence of two signs among fever, headache, neck stiffness, and altered mental status eliminated meningitis with a negative predictive value of 95%. Given the seriousness of bacterial meningitis, clinicians perform lumbar puncture (or brain imaging) too often, especially in high-risk patients. Further prospective clinical research is needed to improve the accuracy of bacterial meningitis clinical diagnosis.

We report a 4-year-old boy with fulminating meningitis caused by Haemophilus influenzae (Hib). He suddenly developed fever, vomiting and then somnolence. As bacterial meningitis was suspected, treatment with antibiotics was started at 12 hours after the onset. However, there was a rapid progression of severe brain edema and brain hernia, leading to clinical brain death. His clinical course and neuroradiological findings mimicked those in patients with acute encephalopathy, with cytokine profiles in cerebrospinal fluid demonstrating a marked increase of inflammatory cytokines. From a review of the literature, fulminating Hib meningitis may be classified into two disease types: DIC plus multiple organ failure and acute brain swelling types. The present case belongs to the latter type, in which cytokine storm seems to play an important pathogenic role.

Bacterial meningitis is a neurological emergency. Empiric antimicrobial and adjunctive therapy should be initiated as soon as a single set of blood cultures has been obtained. Clinical signs suggestive of bacterial meningitis include fever, headache, meningismus, vomiting, photophobia, and an altered level of consciousness. The peripheral white blood cell count with a left shift, an elevated serum procalcitonin and C-reactive protein, and a cerebrospinal fluid pleocytosis with a predominance of polymorphonuclear leukocytes, and a decreased glucose concentration are predictive of bacterial meningitis. Patients with documented bacterial meningitis and those in whom the diagnosis is a strong possibility should be admitted to the intensive care unit. Timely recognition of bacterial meningitis and initiation of therapy are critical to outcome.

Strongyloidiasis, a chronic infection caused by the intestinal parasite Strongyloides stercoralis, is prevalent in the Nansei Islands of Japan. Here, we report our findings on a case of strongyloidiasis complicated with steroid-resistant minimal change nephrotic syndrome in a 69-year-old male resident of Fukuoka Prefecture who had lived in Yakushima, one of the Nansei Islands, until age 15. In October 2006, he developed proteinuria and edema, and was diagnosed with minimal change nephrotic syndrome on the basis of the renal biopsy findings. Following treatment with prednisolone, the level of proteinuria decreased to 0.29 g/day by day 35. However, 5 days later (day 40), the patient developed persistent watery diarrhea and vomiting, leading to dehydration and malnutrition. Pneumonia and bacterial meningitis subsequently developed (day 146); filarial (infectious-type) and rhabditiform (noninfectious-type) S. stercoralis larvae were detected for the first time in the patient's sputum, gastric juice, feces, and urine. Although treatment with ivermectin was started immediately and the parasitosis responded to the treatment, the patient died of sepsis. Consequently, although strongyloidiasis is a rare infection except in endemic regions, it is essential to consider the possibility of this disease and begin treatment early for patients who have lived in endemic areas and who complain of unexplained diarrhea during steroid-induced or other immunosuppression.

We report a rare case of urinary retention secondary to meningitis. A 15-year-old previously healthy male patient admitted to our clinic with complaint of fever, inability to urinate and vomiting, with a two-day history of clavulanate amoxicillin usage. Lumbar puncture was performed, demonstrating a cloudy cerebrospinal fluid (CSF), with protein concentration of 86 mg/dl and glucose concentration of 72 mg/dl, and simultaneous blood glucose of 137 mg/dl. Cell count was 170/microL (neutrophil 154, lymphocyte 11), latex agglutination was negative and no microorganism was detected with Gram stain; there were few polymorphonuclear leukocytes with Wright stain. Cranial tomography was normal and CSF culture and blood culture did not yield any microorganisms. He was treated with ceftriaxone as empirical therapy for bacterial meningitis. In just six days after admission, voiding inability had recovered completely. Although acute urinary retention in patients with meningitis may be self-limited and there is no evidence that any treatment affects its clinical course, physicians should be aware of acute urinary retention as a rare but critical manifestation of meningitis.

Meningococcal infections may develop as episodic or endemic cases particularly among children attending day-care centers, boarding schools or among military personnel. Bivalent (A/C) meningococcal vaccine is applied to all new military stuff since 1993 in Turkey. In this report two cases of meningococcemia and meningitis, developed in two soldiers vaccinated with meningococcal vaccine, were presented. The first case was a 21 years old male patient who was admitted to the emergency service with the complaints of high fever, headache, fatigue and vomiting. He was conscious, cooperative and oriented with normal neurological findings. Maculopapular exanthems were detected at the lower extremities. The patient was hospitalized with the initial diagnosis of sepsis or meningococcemia and empirical treatment was initiated with ceftriaxone and dexamethasone. Cerebrospinal fluid (CSF) examination yielded 10 cells/mm3 (lymphocytes) with normal CSF biochemical parameters. A few hours later skin rashes spread over the body rapidly, the symptoms got worse, confusion, disorientation and disorientation developed, and the patient died due to cardiac and respiratory arrest at the seventh hour of his admission. The second case was also a 21 years old male patient who was admitted to the hospital with the complaints of fever, headache, painful urination, confusion and agitation. He was initially diagnosed as acute bacterial meningitis due to clinical (stiff neck, positive Kernig and Brudzinsky signs) and CSF (8000 cells/mm3; 80% polymorphonuclear leukocytes, increased protein and decreased glucose levels) findings. Empirical antibiotic therapy with ceftriaxone was initiated and continued for 14 days. The patient was discharged with complete cure and no complication was detected in his follow-up visit after two months. The first case had an history of vaccination with bivalent (A/C) meningococcal vaccine three months ago and the second case had been vaccinated one month ago. The bacteria isolated from the blood culture of the first case and the CFS culture of the second case, were identified as Neisseria meningitidis by conventional and API NH system (BioMerieux, France). The isolates were serogrouped as W135 by slide agglutination method (Difco, USA), and both were found to be susceptible to penicillin and ceftriaxone. As far as the last decade's literature and these two cases were considered, it might be concluded that N.meningitidis W135 strains which were not included in the current bivalent meningococcal vaccine, gained endemic potential in Turkey. Since N.meningitidis W135 strains may lead to serious diseases, vaccination of the risk population with the conjugate tetravalent meningococcal vaccine (A/C/Y/W135) should be taken into consideration in Turkey.
