Because of its clinical polymorphism and the difficulties to made a bacteriological and/or serological diagnosis, leptospirosis is an affection always non-detected. Nevertheless it is daily met affection in French Polynesia. Based on a homogenous series of 120 observations gathered from 1984 to 1990, all of them bacteriologically and/or serologically confirmed, we studied the different clinical and evolutive features of that disease. Fever is present in 91.6 p.c., cephalgia in 79.16 p.c. and myalgia in 70.83 p.c. Admission was necessary once out of four times. The four syndromes we observed in Tahiti are: infections syndrome, meningeal syndrome (30 p.c.) associated to an hyperproteinic grade in the C.S.F. (40 p.c.) and a lymphocytic reaction (60 p.c.). Liver syndrome, with hepatalgia (58.33 p.c.) and pain at the mass motion of liver (65 p.c.), that is an important sign in the local context; jaundice (28.33 p.c.) on the presence of which we must not based a diagnosis of leptospirosis: Biological renal syndrome displayed by transitory renal insufficiency with proteinuria, hematuria and leucocyturia. Neurological complications are mainly of encephalitic manifestations (5.8 p.c.). Hemorrhagic syndrome is expressed in digestive hemorrhage (8.33 p.c.) epistaxis (6.66 p.c.) and hemoptysis (6.66 p.c.). Cardiovascular manifestations are expressed in collapsus in 5.83 of the cases. Pulmonary abnormalities are frequent: cough (26.66 p.c.) and non specific X Ray image (19.16 p.c.). All patients are treated by Penicillin G (10 to 20 millions per day) by parenteral route with enteral alternative for an average of 10 days. Recovery was fast (7 to 10 days). In 65.8 p.c., slower in 15 p.c. (15 to 20 days); failure at first stage was observed in 10 p.c. of the cases, and relapse at medium or long term occurred under treatment in 8 cases (6.66 p.c.). Three dead were deplored (mortality 2.5 p.c.).

The clinical and laboratory findings, and the results of treatment of 16 Meningococcal meningitis cases, who were hospitalized, are investigated, and discussed with the literature. On application all of the patients had headache, meningeal irritation findings, and fever (% 75), nausea and vomiting (% 62.5), rash (% 56.25), unconsciousness (% 50), coma state (% 31.25), Herpes labialis (% 31.25), affecting of cranial nerves (% 12.5), arthritis (% 12.5), and carditis (% 6.25). At the peripheric blood examinations, all had leucocytosis, and neutrophilia. In the direct examination of the cerebrospinal-fluid, in 15 patients gram negative diplococci were seen, and in 11 patients the microorganisms grew on culture. The patients were given Crystalized-Penicillin in doses of 20-30 million IU/day. In the two cases some complications, resistance, and allergy developed, so the treatment changed. Only a patient died, and in the other cases no relapse and sequel were seen.

One hundred forty-two children with presumed Group A beta-hemolytic streptococcal (GABHS) pharyngitis were enrolled in a randomized double blind prospective study comparing the consequences of immediate penicillin treatment with treatment delayed for 48 to 56 hours. One hundred fourteen of the enrolled patients were culture-positive. An adverse impact of early antibiotic therapy was noted; the incidence of subsequent infections with GABHS was significantly greater in those treated at the initial office visit with penicillin. In the month following documented evaluation of GABHS, a recurrence occurred 2 times more frequently in those treated with penicillin immediately compared with those for whom treatment was delayed 48 to 56 hours. Late recurrences (beyond 1 month but in the same streptococcal season) occurred 8 times more frequently (P less than 0.035). Delay in penicillin treatment did not increase GABHS intrafamilial spread. Symptoms of both groups were assessed for 2 days following the initiation of treatment. Both placebo-treated and penicillin-treated groups used aspirin or acetaminophen ad libitum. Penicillin was shown to reduce fever and relieve sore throat, dysphagia, headache, abdominal pain, lethargy and anorexia significantly beyond that achieved with aspirin or acetaminophen alone. Penicillin had no effect on culture-negative cases.

A 15 year old boy was admitted to hospital with five days history of fever, headache, vomiting and otorrhea. Findings on physical examination included high fever, purulent drainage from right ear, nuchal rigidity, Brudzinski's and Kernig's signs. Laboratory finding was polymorphonuclear leukocytosis. Computerized tomography (CT) of his brain was normal. A lumbar puncture disclosed purulent CSF. Chloramphenicol and Penicillin G were given intravenously as treatment for the meningitis. After five days of this therapy he continued to be febrile and nuchal rigidity, Brudzinski's and Kerning's signs increased. The second CT demonstrated the presence of an abscess in the cerebellum. The abscess was aspirated during mastoidectomy. In the cultures of the aspiration material Bacteroides species and gram positive micrococci grew out. Metronidazole, 500 mg qid per oral, was added to the therapy. During treatment, his condition was evaluated with serial computerized tomography scans of his brain and these studies showed progressive decrease in the size of the lesion. Metronidazole and antibiotics therapies were continued 45 days. The patient made an uneventful recovery.

Seventy-seven episodes of pneumococcal meningitis in 69 patients were reviewed. Twelve (15.6%) episodes occurred in those over 60 years old, 14 (18.2%) in patients between 10 and 60 years, 22 (28.6%) in patients between 2 and 10 years and 29 (37.7%) in those under 2 years. Overall mortality was 13.0% (10/77) and age of > 60 years was significantly associated with mortality (P < 0.05). Twelve episodes resulted in disabilities, eight of which were in those under 2 years, and took the form of hearing impairment in nine. Many patients had predisposing conditions with aural pathology, malignancy and diabetes mellitus being commonest in those over 10 years of age and aural pathology, preceding viral infection, renal disease, sinusitis or recent lower respiratory tract infection commonest in those aged between 2 and 10 years. Three of five patients with recurrent meningitis had CSF leaks. The most common features at presentation were fits, irritability, diarrhoea, and bulging fontanelles in those under 6 months; vomiting, drowsiness and poor feeding in those between 6 months and 2 years; neck stiffness, vomiting and drowsiness in those between 2 and 10 years while neck stiffness, focal neurology, headache and vomiting were commonest in those over 10 years old. Fever was common in all age groups as were foci of infection outside the CSF, with chest infections being significantly associated with mortality (P < 0.05). Of the laboratory parameters measured, low platelets (< 100 x 10(9)/l and high blood urea (> 7 mmol/l) were associated with mortality (P < 0.05). Blood cultures grew Streptococcus pneumoniae in 79.7% patients. Seventy-four (96%) patients had CSF taken of which 81% had gram films which were positive and interpreted correctly as showing pneumococci. Pneumococci were grown in 87.8% CSF cultures and all were sensitive to penicillin but a single isolate was chloramphenicol resistant. Many different antimicrobial drugs were used but penicillin plus chloramphenicol was the most commonly employed after the results of CSF microscopy were known and penicillin alone after culture results were available. Penicillin mono-therapy was associated with a low mortality.

GABHS is the most common bacterial cause of tonsillopharyngitis, but this organism also produces acute otitis media; pneumonia; skin and soft-tissue infections; cardiovascular, musculoskeletal, and lymphatic infections; bacteremia; and meningitis. Most children and adolescents who develop a sore throat do not have GABHS as the cause; their infection is viral in etiology. Other bacterial pathogens produce sore throat infrequently (e.g., Chlamydia pneumoniae and Mycoplasma pneumoniae), and when they do, other concomitant clinical illness is present. Classic streptococcal tonsillopharyngitis has an acute onset; produces concurrent headache, stomach ache, and dysphagia; and upon examination is characterized by intense tonsillopharyngeal erythema, yellow exudate, and tender/enlarged anterior cervical glands. Unfortunately only about 20% to 30% of patients present with classic disease. Physicians overdiagnose streptococcal tonsillopharyngitis by a wide margin, which almost always leads to unnecessary treatment with antibiotics. Accordingly, use of throat cultures and/or rapid GABHS detection tests in the office is strongly advocated. Their use has been shown to be cost-effective and to reduce antibiotic overprescribing substantially. Penicillin currently is recommended by the American Academy of Pediatrics and American Heart Association as first-line therapy for GABHS infections; erythromycin is recommended for those allergic to penicillin. Virtually all patients improve clinically with penicillin and other antibiotics. However, penicillin treatment failures do occur, especially in tonsillopharyngitis in which 5% to 35% of patients do not experience bacteriologic eradication. Penicillin treatment failures are more common among patients who have been treated recently with the drug. Cephalosporins or azithromycin are preferred following penicillin treatment failures in selected patients as first-line therapy, based on a history of penicillin failures or lack of compliance and for impetigo. GABHS remain exquisitely sensitive to penicillin in vitro. There are several explanations for penicillin treatment failures, but the possibility of copathogen co-colonization in vivo has received the most attention. Treatment duration with penicillin should be 10 days to optimize cure in GABHS infections. A 5-day regimen is possible and approved by the United States Food and Drug Administration for cefpodoxime (a cephalosporin) and azithromycin (a macrolide). Prevention of rheumatic fever is the primary objective for antibiotic therapy of GABHS infections, but a reduction in contagion and faster clinical improvement also can be achieved. Development of streptococcal toxic shock syndrome and necrotizing fasciitis ("flesh-eating bacteria") are rising concerns. The portal of entry for these invasive GABHS strains is far more often skin and soft tissue than the tonsillopharynx.

There are three clinical presentations of anthrax in humans: cutaneous (>95% of cases), orogastric and inhalational. The infectious form, the spore, enters the body and is thought to germinate within macrophages either at the site of inoculation (cutaneous or orogastric) or in the regional lymph node (inhalational). The bacillus then synthesizes its antiphagocytic capsule and the lethal and oedema toxins which interfere with the non-specific host defences leading to the characteristic locally destructive lesion and spread by lymphatics to the systemic circulation and other organs. The cutaneous form begins as a papule which progresses over several days to a vesicle and then ulcerates. There is often oedema, sometimes massive, probably due to the oedema toxin that surrounds the lesions which then develop a characteristic black eschar. The patient may be febrile with mild to severe systemic symptoms of malaise, headache and toxicity. Oropharyngeal anthrax presents with severe sore throat or an ulcer in the oropharyngeal cavity associated with neck swelling, fever, toxicity and dysphagia. Gastrointestinal anthrax begins with anorexia, nausea, vomiting and abdominal pain which may be similar to an acute abdomen. There may be diarrhoea and ascites, both of which may be haemorrhagic. Inhalational anthrax begins with non-specific symptoms of malaise, fever, myalgia and non-productive cough. After a period of 2-3 days, this is followed by a sudden onset of severe respiratory distress associated with diaphoresis, cyanosis and increased chest pain. There may be a widened mediastinum and pleural effusions on chest X-ray. Death follows in 24-36 h from respiratory failure, sepsis and shock. The diagnosis of anthrax is easy if it is considered. The organism is readily observed by Gram or Wright stain in local lesions or blood smear and can be easily cultured from the blood and other body fluids. However, because of its rarity, it is not often included in the differential diagnosis and in inhalational disease the diagnosis is rarely made until the patient is moribund. More rapid diagnostic tests are under development. Penicillin, combined with supportive care, remains the mainstay of treatment, although the organism is susceptible in vitro to many antibiotics. In recent years, there have been significant advances in our knowledge of the organism and its toxins and it is anticipated that similar progress will be made in the future in developing more rapid diagnostic tests and new modalities of treatment.

The authors report a case and treatment of multiple brain abscesses located in the cerebrum and cerebellum combined with subdural empyema. In conjunction with the case report, the authors review the literature on the pathogenesis of brain abscesses and discuss therapeutic strategies concerning the topic. In the case presented, the primary infection persisted in the lung causing subclinical bronchitis. The hemoculture showed evidence of Streptococcus mitis infection. Although the etiological role of this bacterium in meningitis is known, it rarely causes bacterial meningitis without underlying predisposing factors. In their case, the patient was free of the most common predisposing factors such as congenital heart disease or immunodeficiency. Following the 2 month period of latency, a rapid onset of the symptoms of intracranial inflammation could be observed: fever, headache, meningeal symptoms, focal neurological symptoms and coma. They were not able to identify any bacteria in the cerebrospinal fluid; the Streptocossus mitis could be cultivated only from the haemoculture. The cytological analysis of the cerebrospinal fluid showed typical signs of bacterial infection and the cranial Computed Tomography revealed multiple cerebral abscesses. Neurosurgical intervention was not recommended because of the number, localization and size of the focal lesions. The therapy consisted of intravenous administration of 24 x 10(6) IU/die Penicillin and 4 g/die ceftriaxon. For supportive therapy, Mannitol B, 3 mg/die clonazepam and 300 mg/die phenytoin were administered. Corticosteroids were not used during the course of therapy. Two years later the 55 year old female is symptom free and doing well.

Pasteurella multocida meningitis is a rare clinical occurrence. We report a new case and review the 28 other cases described in the English literature. A history of recent animal contact remains strongly associated with P. multocida meningitis (noted in 89% of all cases), with licking of mucus surfaces or injured skin being most common. Bacteremia was present in 63% of all patients. Spread from an adjacent site of infection continues to be an important factor, with otitis media being documented or strongly suspected in 24% of all cases. The presenting signs and symptoms were characteristic of bacterial meningitis, with fever, headache, nucal rigidity and an altered level of consciousness being present in most patients. Cerebrospinal fluid analysis was typical for bacterial meningitis. Penicillin G or ampicillin was the most common definitive treatment; however, third-generation cephalosporins have been successful. The mean duration of treatment was 14 d. Neurologic complications were present in 17% of patients overall and mortality remains substantial at 25%. Although not statistically significant, there is a trend toward decreased neurologic complications and mortality during the last 11 y.

Neurosyphilis follows a more aggressive and different clinical course in HIV-infected patients compared to patients with normal immunity. Two historical series of patients with a diagnosis of neurosyphilis between 1995 and 2008 were compared: they included a group of 15 patients with y and 28 patients without HIV infection. Probability of neurosyphilis in patients with positive serum VDRL was increased in patients infected with HIV compared to HIV negative patients (OR: 62.37 IC:95% (32.1-119.1) p value:< 0,001). Predominant clinical manifestations in neurosyphilis in the HIV negative group were ocular abnormality, vascular encephalic and spinal cord lesions. In the HIV positive group, they were fever, ocular abnormalities and headache. There were no differences in cerebrospinal fluid characteristics between both groups. Neurosyphilis was diagnosed even in patients with blood VDRL of < 1:32, that happened in 17.8% of the HIV positive patients with blood and in 60% of t he HIV negative patients. Penicillin sodium given at dose >or= than 18.000.000 IU/day IV during 14 days was the most common treatment. In patients with clinical neurosyphilis, 93% of HIV negative group, and 54.2% of HIV positive group had persistent neurological after-effects. Three HIV positive patients died due to causes not related to neurosyphilis.
