We presented atypical manifestations in tuberculous meningitis (TbM) and herpes simplex encephalitis (HSE), lymphocytic dominant cerebrospinal fluid pleocytosis in bacterial meningitis, and a hitherto easily overlooked critical illness polyneuropathy (CIP) associated with sepsis. 1) We presented 2 TbM patients with atypical manifestations. One patient was a 25-year-old man who exhibited polymorphonuclear (PMN) dominant pleocytosis in CSF throughout his clinical course. He died the next day after a CSF culture yielded the growth of tuberculous bacilli, before receiving appropriate anti-TBM therapy. This was a rare TbM example of persistent PMN dominant CSF pleocytosis. The other patient was a 39-year-old woman whose CSF pleocytosis changed from lymphocytic dominant to PMN dominant about 1 month after the initiation of antituberculous chemotherapy. This CSF change was followed by multiple cerebral infarcts due to vauculitis caused by TbM. Administration of prednisolone caused marked improvement of the patient's symptomatology. Tuberculomas appeared transiently during anti-TbM therapy, consistent with paradoxical progression of tuberculoma. 2) A few patients with HSE may show atypical CSF findings such as PMN dominant pleocytosis, absence of pleocytosis, and low sugar value. Our national survey of HSE patients showed following percentages of these atypical findings: PMN dominant pleocytosis observed in 10% of the patients in the early stage and at the time of exacerbation, no pleocytosis in 0.9% (1 patient), and low sugar value in 4%. 3) Bacterial meningitis typically causes PMN dominant CSF pleocytosis. However, Listeria meningitis (LM) may cause lymphocytic dominant pleocytosis in 30% of the patients, particularly in elderly ones. We showed one such 69-year-old patient with persistent lymphocytic dominant CSF pleocytosis throughout the clinical course. 4) CIP, septic encephalopathy and critical illness myopathy are 3 major complications associated with sepsis. CIP is a frequent cause of neuromuscular weakness due to axonal dysfunction, which occurs to critically ill patients with sepsis, particularly when multiple organ dysfunctions are present. We showed our CIP patient associated with acute bacterial endocarditis and multiple organ failure. We should bear in mind these atypical manifestations, and frequent and important complications associated with sepsis such as CIP, to provide appropriate management to patients with neuro-infection and sepsis.

A 69-year-old man with relapsed acute lymphoid leukemia was treated with adriamycin, vincristine, and prednisolone. During this chemotherapy, the patient developed sepsis and meningitis. Although many kinds of antimicrobial drugs, including imipenem, meropenem, amphotericin-B, and gamma-globulin were administered, the patient died of respiratory failure. A positive result for Enterococcus faecalis was obtained in both blood and cerebrospinal fluid culture. Autopsy revealed multiple small erosions in the lower esophagus. Histopathological examination showed multiple nuclear inclusion bodies of herpes simplex virus in the squamous epithelial cells at the edge of the erosions. Moreover, proliferation of micrococci was observed at the base of the erosions and in the lumina of the submucosal small vessels. These findings suggested that E faecalis entered the blood circulation from this lesion. In many patients with febrile neutropenia, the pathogenesis of infection remains unclear. Our case seems significant for clarifying the focus and pathogenesis of febrile neutropenia.

Human neonates infected with herpes simplex virus 1 (HSV-1) develop one of three distinct patterns of infection: (i) infection limited to the skin, eye or mouth; (ii) infection of the CNS; or (iii) disseminated infection. The disseminated form usually involves the liver, adrenal gland, and lung, and resembles the clinical picture of bacterial sepsis. This spectrum of symptoms in HSV-1-infected neonates suggests that inflammatory cytokines play a significant role in the pathogenesis of the disease. Recent studies suggest that the Toll-like receptors (TLRs) may play an important role in the induction of inflammatory cytokines in response to viruses. TLRs are mammalian homologues of Toll, a Drosophila protein that is essential for host defense against infection. Engagement of TLRs by bacterial, viral, or fungal components leads to the production and release of cytokines and other antimicrobial products. Here, we demonstrate that TLR2 mediates the inflammatory cytokine response to HSV-1 by using both transfected cell lines and knockout mice. Studies of infected mice revealed that HSV-1 induced a blunted cytokine response in TLR2(-/-) mice. Brain levels of monocyte chemoattractant protein 1 chemokine were significantly lower in TLR2(-/-) mice than in either wild-type or TLR4(-/-) mice. TLR2(-/-) mice had reduced mortality compared with wild-type mice. The differences between TLR2(-/-) mice and both wild-type and TLR4(-/-) mice in the induction of monocyte chemoattractant protein 1, brain inflammation, or mortality could not be accounted for on the basis of virus levels. Thus, these studies suggest the TLR2-mediated cytokine response to HSV-1 is detrimental to the host.

Ten of 11 cell lines, recently established from the snout (MS-SN), periorbital soft tissue (MS-EY), liver (MS-LV), kidney (MS-KD), lung (MS-LG), spleen (MS-SP), heart (MS-HT), thyroid (MS-TY), brain (MS-BR) and urinary bladder (MS-UB) of a juvenile Hawaiian monk seal Monachus schauinslandi, were evaluated in vitro for their susceptibility to 5 mammalian viruses: herpes simplex virus type 1 (HSV-1), vesicular stomatitis virus (VSV), reovirus type 3 (Reo-3), poliovirus type 1 (Polio-1) and vaccinia virus (Vac); 5 fish viruses: channel catfish herpesvirus (CCV), infectious hematopoietic necrosis virus (IHNV), infectious pancreatic necrosis virus (IPNV), fish rhabdovirus carpio (RC) and viral hemorrhagic septicemia virus (VHSV); and 2 marine mammal morbilliviruses: phocine distemper virus (PDV) and dolphin distemper virus (DMV). Four well-established continuous cell-lines of nonhuman primate (Vero) and fish (EPC, CHSE-214 and BB) origin served as controls to standardize the virus infectivity assays. Virus yields were quantified as 50% tissue culture infectious dose (TCID50) ml(-1) on Day 7 post-inoculation. Results of the viral challenge assays revealed that the monk seal cell lines shared a similar pattern of susceptibility to the mammalian viruses. Despite their different tissue origins, all monk seal cells were sensitive to HSV-1, Vac, VSV and Reo-3, but were refractory to Polio-1. A characteristic viral-induced cytopathic effect was noted with VSV and Reo-3, and distinct plaques were observed for HSV-1 and Vac. Monk seal cell lines were also susceptible to PDV and DMV, 2 morbilliviruses isolated from seals and dolphins, respectively. By contrast, these cell lines were generally resistant to VHSV, IHNV and IPNV, with varying susceptibility to RC and CCV. The wide range of viral susceptibility of these monk seal cell lines suggests their potential value in studying viruses of monk seals and other marine mammals.

Authors wanted to draw attention to possibility of dangerous postoperative complications when the clinical manifestation of reactivation Herpes simplex virus infection develops during the postoperative period. We report a case of parapharyngeal phlegmon following tonsillectomy in a previously healthy 18-year old woman. On postoperative day six signs of Herpes simplex virus infection were presented in our patient. Hypoimmunity causing reactivation of virus led to evolution of septicemia and extended parapharyngeal phlegmon. Management involved parapharyngeal space drainage, broad spectrum antibiotics and gammaglobulin coverage. Treatment was successful. The patient was discharged in good condition in the fourth week of her admission.

Recent aspects of pathogen determination and therapeutic management are reviewed based on a clinical analysis of 50 of our adult patients with bacterial meningitis (BM). The sensitivity for detecting pathogens using gram-stained smears and cultures of CSF was high in untreated patients, but low in patients previously treated with antibiotics. Latex agglutination for antibodies of pathogens is rapid and has a potential for determining pathogens in partially treated meningitis. The PCR also has a potential for determining pathogens in pre-treated, culture-negative cases and for detecting whether the bacterial pathogen is resistant or sensitive to antibiotics. The initial empiric regimen of antibiotics has been modified with elevation in the detection rate of drug-resistant bacilli. The proportion of patients undergoing treatment with VCM and/or Carbapenems has recently increased at our department. A combination of dexamethasone under administration of antibiotics has also been established as effective in adult BM. On admission, some patients are difficult to diagnose as BM rather than herpes simplex encephalitis (HSVE). A serum CRP value of >2.0 mg/dl proved useful for such different diagnosis in our patients. The predictors of a poor outcome based on multivariate logistic analysis in our BM patients were level of unconsciousness and sepsis.

Toll-like receptors (TLRs)--and their associated signal-transducing proteins--on the surface of cells have been demonstrated to account for most, if not all, of the events associated with bacterial sepsis. Using human cells expressing different TLRs, we demonstrated that the interaction between TLR2 and herpes simplex virus (HSV)-1-2 leads to the production of cytokines. Using peripheral-blood mononuclear cells, we tested the ability of cells from people of different age groups to make cytokines in response to HSV. An examination of the host responses of neonates to HSV indicates that, rather than producing less interleukin-6 and interleukin-8 in response to HSV than adults do, neonates produce more of these cytokines than adults do. This may explain the sepsis syndrome that is seen with HSV (and other virus infections) in neonates.

Side effects of calcineurin inhibitors (CNIs) include nephrotoxicity and hypertension. Moreover, children have a higher risk of infections and posttransplantation lymphoproliferative disorders. We retrospectively evaluated the efficacy and safety of Sirolimus (SRL) in 18 patients, who were 10.52 +/- 5.03 years at time of transplantation and received a CNI as the core immunosuppression. The most common indications for starting SRL therapy were chronic allograft nephropathy, Epstein-Barr virus-associated neoplasia, and thrombotic microangiopathy. The patients were converted to SRL at 49.14 +/- 45.9 months posttransplantation. Mean follow-up after the switch to SRL was 13.83 +/- 7.24 months. All patients who began SRL therapy remained on that medication. We observed a significant improvement (P < .05) in glomerular filtration rate assessed using the Schwartz formula at 3 months, which was sustained thereafter. There were no changes in proteinuria, plasma lipids, and platelet number. Although the prevalence of hypertensive patients decreased during follow-up, it was not significant. There was one steroid-sensitive, acute rejection episode. Serious adverse events included 1 death due to a relapse of B lymphoma, 1 sepsis, and 1 pancreatic pseudo-cyst. Adverse events were present in 17% of patients: 3 Herpes Simplex infections, and 1 dose-related lymphedema. Further studies are necessary to assess the impact of adverse events in the pediatric transplant population receiving SRL as immunosuppression.

Viral encephalitis is associated with significant morbidity and mortality, particularly when appropriate management is omitted as a result of delayed diagnosis. A case of herpes simplex virus type 1 (HSV-1) encephalitis is presented, demonstrating that the presentation of confusion, speech difficulties and fever with non-specific early brain CT appearances can easily be misdiagnosed as pneumonia with stroke. This case highlights the need for increased awareness of HSV-1 encephalitis among emergency physicians and radiologists, given that the early spectrum of clinical and CT findings can mimic the more common diagnoses of sepsis and stroke.
