Eighty four cases of meningococcal infections are reviewed. Fifty seven cases presented themselfs as meningococcal meningitis, twelve cases as sepsis with moderate hypotension and 15 cases were sepsis with septic shock. A brief course of the disease, shock, echymosis, absence of meningeal signs, leucopenia and intravascular coagulation were findings more frequent in the group of patients with hiperacute sepsis, whereas other signs as fever, headaches, vomiting and petechiae were present with equal frequency in the three groups. N. meningitis was isolated in 73% of the cases. Shock (18.85%) and intravascular coagulation (12%) were the complications more frequently found, followed by convulsions (4.81%), arthritis (4.81%), skin necrosis (4.81%), subdural efusion (3.57%), cerebral palsy (3.40%), thrombophlebitis (1.20%), recurrence (1.20%), inapropiate antidiuretic hormone secretion (1.20%) and subaracnoideal hemorrage (1.20%). The overall mortality was 10.70% and 60% of the patients which initially presented with shock and intravascular coagulation died. Autopsy findings included wide spred hemorragic lesions and intravascular thrombi in skin, mucous membranes and viscera. Adrenal hemorrhage was present in five of the six cases studied.

Minocycline hydrochloride is a tetracycline derivative that has been advocated as the drug of choice in the treatment of meningococcal carriers. Recently, we studied a group of 30 patients who experienced a large number of side-effects after receiving minocycline for treatment of meningococcal meningitis. Twenty-seven of 30 (90%) suffered from dizziness, vertigo, ataxia, weakness, nausea, and vomiting. These symptoms appeared within the first 72 hours of taking minocycline, and disappeared within 48 hours of stopping the medication.

The relationship of symptoms and signs to age and the reasons for consulting a physician were analyzed in 110 cases of culture-proven childhood bacterial meningitis. H. influenzae caused 74, meningococci 28, pneumococci 6 and streptococci 2 of the cases. Apart from fever (present in 94%), the most common symptoms according to age were as follows: 1-5 months: irritability (85%), 6-11 months: impaired consciousness (79%), 12 months or more: vomiting (82%) and neck rigidity (78%). Absence of neck rigidity at diagnosis was associated with young age (less than 12 months, P less than 0.001) and, in older children, to a short duration of symptoms (P less than 0.01) but not to the degree of CSF pleocytosis. Symptoms of meningitis caused by H. influenzae differed from those of meningococcal meningitis. Meningitis should be suspected in irritable or lethargic febrile children despite absence of neck rigidity. Fever and vomiting were the most frequent reasons for consulting a physician (60% and 31%, respectively). Despite the frequency and alarming character of irritability, impaired consciousness and neck rigidity, their presence led infrequently to a consultation (6%, 22% and 3%, respectively). Parental ignorance of such symptoms or of their importance may cause treatment delay, despite readily available medical services.

One hundred twenty four cases of meningococcal meningitis were seen at the Ethio-Swedish Children's Hospital (ESCH) during the epidemic period December 1, 1987 to January 31, 1989. Data on demographic and clinical profile of patients were collected and analyzed. Two thirds of patients were above 5 years of age. Fifty percent of the patients came from the "mercato area" of the city of Addis Abeba, Higher 3, 4, 5 & 6. Thirteen cases were from outside Addis Abeba. The main clinical presentations were fever and vomiting in all age groups and headache in those above 5 years of age. The classical meningeal signs were rare in those below 5 years of age. The most common neurological deficit was loss of hearing. Mortality was very low (only 3 deaths). Continuous surveillance of demographic and clinical indicators is recommended as they could be useful early warning signs of an epidemic.

Despite its common association with viral illnesses, intussusception has only rarely been found in the presence of bacterial infections. Two infants are described, both of whom were admitted to hospital with bilious vomiting, drowsiness, and dehydration. Both infants required urgent intravenous volume expansion. Intussusception was confirmed, and reduction was achieved by enema in both cases. Recovery was slow, and one infant developed a seizure. Evidence of meningococcal meningitis was found in both, with septicaemia in one. Neurological outcome is normal to date, and there has been no recurrence of intussusception in either case.

Meningococcal meningitis has been occurring worldwide in both endemic and epidemic forms. Serogroup A accounts for majority of cases of epidemic as well as endemic Meningococcal meningitis in developing nations, whereas group C and group B causes epidemic and endemic meningococcal meningitis in developed countries. Person to person spread of N. meningitides generally occurs through inhalation of droplets of infected nasopharyngeal secretions by direct or indirect oral contact. Incubation period varies from 2 to 10 days. N. meningitides typically causes acute infective illness characterized by sequential development of upper respiratory tract infection, meningococcemia, meningitis and focal neurological deficit. Over 90 per cent cases of adult meningococcal infections have cerebrospinal meningitis, whereas in children prevalence of meningitis is much lower (50 per cent). Acute meningitis manifests with fever, severe headache, vomiting and neck stiffness. Presentations may be non-specific in infants, elderly and in patients with fulminant meningococcemia. Diagnosis is confirmed with cerebrospinal fluid analysis. Overall mortality due to meningitis is usually around 10 per cent. In meningococcal septicemia, the case fatality rate may exceed 50 per cent. Preventive strategies include vaccination, chemoprophylaxis and early detection and treatment. Mass vaccination campaign, if appropriately carried out, has been documented to halt an epidemic of meningococcal disease due to serogroup A or C. In the present review we have discussed the available evidence with regards to prevention at primary, secondary and tertiary level. Public health approach to an outbreak of meningococcal meningitis in a community or an organization is also outlined.

Spinal cord dysfunction is a rare complication of Neisseria meningitidis (meningococcal) meningitis. We report a 17-year-old patient who had a 3-day history of fever, headache and vomiting, agitation, and unresponsiveness. Cerebrospinal fluid showed a marked polymorphonuclear pleocytosis. Latex particle agglutination was positive for meningococci. The patient was given intravenous antibiotics and intravenous dexamethasone. Over the next 4 days, he developed weakness of the lower extremities, with areflexia and extensor plantar responses. MRI revealed contiguous hyperintensities on T2-weighted images involving the thoracic spinal cord from T4 to T9 and 4 brain abscesses. Five months later, he recovered brain function, but the paraparesis remained. This case illustrates that myelopathy may complicate acute meningococcal meningitis, possibly due to a vasculitis, stroke, autoimmune myelopathy, or direct infection of the spinal cord. Patients with myelopathy associated with acute meningitis should receive spinal MRI. In addition, meningitis should be considered in patients presenting with acute myelopathy.

Meningococcal septicaemia has high mortality, especially when the diagnosis is delayed or missed. Early recognition is not always straightforward, as classic clinical features may be absent or overlooked at initial presentation. Septicaemia without focal infection accounts for 15%-20% of cases of meningococcal disease and is the most worrisome manifestation in terms of diagnosis and outcome; in contrast, meningococcal meningitis is usually straightforward to diagnose, with a relatively good prognosis. Useful early clinical clues to meningococcaemia include: - a haemorrhagic (petechial or purpuric) rash; - blanching macular or maculopapular rash that appears in first 24 hours of illness; - true rigors; - severe pain in extremities, neck or back; vomiting, especially in association with headache or abdominal pain; rapid evolution of the illness; - concern of parents, relatives or friends; - patient age (highest incidence at age 3-12 months, followed by 1-4 and then 15-19 years); and - contact with a patient with meningococcal disease. In addition to specific clues, clinicians should look at the whole pattern of the illness. Timely clinical review is essential if there is doubt about the diagnosis. In any acutely febrile patient, it is prudent to ask "Why is this patient seeking help now?", then "Could this patient have meningococcaemia?".

We present a retrospective analysis of clinical profile of 100 children admitted to a Government hospital at Delhi between April 2005 and December 2006 with group A meningococcal infection. Maximum children presented in late winter and spring. Younger children were less affected (5% children < 1 year). Fever (86%), vomiting (64%) and rash (63%) were the most common presenting symptoms. All children presented within 5 days of onset of symptoms and 52% within 24 hours. 67 % children had meningococcal meningitis; 20% had meningococcemia; and 13% had both. Overall mortality was 17%. Altered sensorium and shock at presentation significantly increased the mortality. All culture positive cases had group A Neisseria meningitides. All meningococcal isolates were sensitive to penicillin/ampicillin, ciprofloxacin, ceftriaxone, chloramphenicol and erythromycin except, one each resistant to ampicillin and erythromycin.

Neisseria meningitidis is an unusual pathogen among the causes of acute bacterial conjunctivitis. Meningococcal conjunctivitis may present as primary or secondary infection, while primary meningococcal conjunctivitis may emerge as invasive or non-invasive forms. N.meningitidis W135 strain is not common in Turkey, and is rarely reported as the cause of meningitis. Moreover, no cases of conjunctivitis due to N.meningitidis W135 were reported from Turkey. In this report a case of N.meningitidis W135 conjunctivitis has been presented who acquired the infection from another patient with meningococcal meningitis by close contact in the hospital environment. A 2-month-old male infant was admitted to our hospital with poor health condition, feeding difficulty and weight loss. He was hospitalized in intensive care unit and fluid replacement started due to severe dehydration. The infant had stigmata of Down's Syndrome, and since conjunctivitis were detected on physical examination, swab samples were obtained from both eyes for direct microscopic examination and cultivation. Abundant lekocytes and gram-negative diplococci were observed in Gram-stained smears, and bacterial growth were detected in the culture from left eye samples. The isolate have been identified as N.meningitidis by conventional microbiological methods, and serotyping of the isolate yielded W135 strain. The infant was treated with systemic cefotaxime and ampicillin-sulbactam, together with topical tobramycin and gentamycin. Since no symptoms of meningitis appeared during the follow-ups, the case was diagnosed as non-invasive primary meningococcal conjunctivitis. Investigation for a probable source revealed that the infant had close contact with a six-year-old boy with high fever, unconsciousness and vomiting a week ago in the outpatient clinic of Tekirdag State Hospital. N.meningitidis was also isolated from the cerebrospinal fluid culture of probable index case with meningitis and identified as W135 strain by serotyping. Both strains isolated from these cases were found similar according to their phenotypical characteristics, however genotyping could not be performed. Since no other sources of exposure could be found, it was concluded that the infant with conjunctivitis acquired the bacteria from the other patient during their shared hospital visit. This patient is the first N.meningitidis W135 conjunctivitis case reported from Turkey.
