Combined measles-mumps-rubella (MMR) vaccines produced by GSK (GSK-MMR) and Merck (Merck-MMR) have demonstrated effectiveness and an acceptable safety profile, as documented over decades of post-licensure use in various regions worldwide. In the United States, 2 doses of the MMR vaccine are recommended at the ages of 12-15 months and 4-6 years. All-cause febrile convulsions have the highest incidence at 12-18 months of age, when the first MMR vaccine dose is administered. Because febrile convulsions can also occur rarely after MMR vaccine administration, we reviewed safety data of the GSK-MMR compared to the Merck-MMR vaccine from 4 clinical trials that evaluated a first dose in 12-15-month-olds and 2 clinical trials that evaluated a second dose in ≥4-year-olds. Overall frequencies of febrile convulsions were ≤0.4% across studies and vaccine groups. The frequency of febrile convulsions occurring 7-10 days post-vaccination with the GSK-MMR vaccine (5.7/10,000) was generally consistent with previously published data. The other safety outcomes were similar between the GSK-MMR and Merck-MMR vaccines in both age groups. Hence, as recommended by the Advisory Committee on Immunization Practices, the GSK-MMR vaccine can also be used for routine immunization of children according to the current immunization schedule in the United States to prevent MMR.

Background: Increasing the posterior fossa volume is the mainstay of treatment for Chiari type 1 Malformation (C1M) and type 1.5 (C1.5M). Different options to restore CSF flow have been described but no consensus has been reached yet. Bony decompression of posterior cranial fossa with dural opening provides good results but at the price of complications such as pseudomeningocele and aseptic meningitis. A single center retrospective analysis was conducted to find any relationships between outcome and perioperative factors. As a second goal a specific analysis was conducted on the complications and their hypothetical causes., Methods: All the pediatric patients who underwent to posterior fossa bony decompression and dural opening for C1M or C1.5M in the period 2008-2020 were included in the study. A minimum period of three-months follow-up was considered among the inclusion criteria., Results: A population of fifty-three consecutive patients was collected. Pseudomeningocele and a mild meningeal irritation resulted the most frequent complications. Considering preoperative and intraoperative factors, the type of dural graft showed a relatively strong correlation (P<.01) with pseudomeningocele appearance and the development of meningism. In the latter case, a short course of steroids was the only treatment required to control symptoms., Conclusions: Different factors could influence the outcome in Chiari Malformation surgery and eventually the development of complications. An adequate dural graft selection is of paramount importance when a dural opening for posterior fossa augmentation is planned. In case of mild meningeal irritation, a trial with short course steroids could avoid revision surgery., (Copyright © 2023 Elsevier Masson SAS. All rights reserved.)

The etiology of hyperventilation is multifactorial. When excluding somatic causes, neurogenic hyperventilation must always be considered. Since hyperventilation itself causes neuromuscular symptoms such as paresthesia, vertigo, cephalgia, and nausea, the differential diagnosis of viral meningitis in the presence of hyperventilation is not always obvious and can easily be overlooked. Our case report shows that somatogenic causes of hyperventilation should be carefully excluded., (© 2022.

A thorough examination of a comatose patient is essential given the spectrum of clinical diagnoses. The most immediate threat to patients is airway, breathing and circulation. All attending physician should employ a structured and focused approach in dealing with a comatose patient. It is important to recognise the urgent steps needed at the time to prevent further deterioration, followed by the final diagnosis of patient's neurologic status. Here we provide the essential practical guide to the neurological exam of a comatose patient that would assist to determine the aetiology, location and nature of the neurological lesion., Competing Interests: Conflict of Interest None., (© Penerbit Universiti Sains Malaysia, 2020.)

Background : Pituitary apoplexy (PA) is a rare but potentially life-threatening condition that may require urgent surgical intervention. Case Presentation : We report a case of a patient who was initially diagnosed with meningoencephalitis (ME) based on clinical presentation and cerebrospinal fluid (CSF) analysis, but was eventually diagnosed with PA. We present a summary of other cases reported in the literature of PA mimicking ME and analyze their clinical features and CSF findings. Results : Among all 22 PA cases reviewed, headache was the most commonly reported symptom. Hypopituitarism was seen in 94.4% of the cases; of these, panhypopituitarism was noted in 38.9%. The sensitivity of magnetic resonance image (MRI) for detecting PA was 94.7%, much higher than that of computed tomography (CT), which was only 31.6%. Neutrophil predominant pleocytosis was present in all cases with a neutrophil percentage ranging from 73% to 98%. CSF leukocyte count was less than 1000/ul in 86% of the cases. CSF erythrocytosis was seen in 92.9% of the cases with a count ranging from 15 to 2030/ul. Elevated CSF protein was present in all cases with a range of 69.8 to 239 mg/dl. CSF glucose level varied with a range between 12 and 136 mg/dl; the level was greater than 40 mg/dl in 73% of the cases. Conclusion : PA tends to be misdiagnosed as ME due to the similarities of semiology and CSF findings. PA should be considered in refractory acute headache cases, especially those with visual and endocrine abnormalities. Early recognition and treatment may lead to significant reduction in morbidity and mortality.

Typhoid fever is usually a mild clinical disease, but it can have potentially serious complications. Here, we describe a case of an adolescent male who presented with severe illness and multi-organ involvement from typhoid fever. He required follow-up after discharge but eventually recovered. Clinicians should be aware of the spectrum of clinical manifestations as early recognition will improve monitoring and management of typhoid disease.

We report a case of disseminated cryptococcosis in a 42-year old immunocompetent female. Prior to admission at Bugando Medical Center, the patient was attended at three hospitals for hypertension and clinically diagnosed malaria. Following diagnosis of disseminated Cryptococcus at our center, she was successfully treated with fluconazole but remained with visual loss. Blood cultures should be considered in the management of any adult presenting with fever to enable early detection of the least expected differentials like in this case.

Isolated fourth ventricle is not uncommon in complex posthemorrhagic or postinfectious hydrocephalus. When the condition is symptomatic, the current surgical treatment is endoscopic aqueductoplasty, followed by endoscope-assisted placement of a catheter in the fourth ventricle. The authors suggest a very simple method of steering the tip of standard ventricular catheters by using materials commonly available in all operating rooms. The main advantage of this method is that it permits less invasive transaqueductal drainage of trapped fourth ventricles, especially in cases of narrow third ventricle, because the scope and catheter are introduced in sequence and not in a double-barreled fashion. Two illustrative cases are reported.

At Ste. Justine Hospital, Montreal, during the period 1957-61, ECHO 9 virus was isolated in 27 cases, in 20 of these during the summer of 1961. All had evidence of meningeal irritation, accompanied by fever and headache. Four of the 20 patients diagnosed during the summer of 1961 had convulsions; 12 presented with a rash; and two simulated meningococcemia. Of the 27 patients, two were paralyzed and one case was diagnosed as transverse myelitis. ECHO 9 virus was isolated from stools and from throat specimens in equal proportion; it was isolated from cerebrospinal fluid in only two instances. Pathogenicity for suckling mice was observed in two of 22 inoculated directly with the specimen material and in 10 of 11 inoculated with the cultured material.
