A 34-year-old man with neurofibromatosis type 1, who had received radiation therapy after the excision of a brain tumor 5 years earlier, was admitted to our hospital with vomiting and weight loss. Cortisol and adrenocorticotropin (ACTH) were undetectable before and after administration of 100 microg corticotropin releasing hormone. The level of growth hormone without stimulation was 24.7 ng/ml. We diagnosed him to have complete ACTH deficiency attributable to radiation therapy. This is the first known case of a patient with complete ACTH deficiency after radiation therapy and a growth hormone reserve that remained normal.

Central neurocytoma (CN) is a rare intraventricular brain tumor that affects young adults. Just over 100 cases of CN have been reported since it was first described in 1982. It accounts for less than 1% of all central nervous system neoplasms. It is characterized by cystic spaces and intratumoral calcification. The tumor is generally hypervascular. Patients generally present with signs and symptoms of noncommunicating hydrocephalus such as headache, visual disturbances such as blurry vision and visual field deficit, and nausea or vomiting or both. Gross total surgical resection is the treatment of choice for CN. Other treatment modalities such as radiation therapy, radiosurgery, and chemotherapy may offer adjunctive or alternative treatment for residual or recurrent CN. The clinical outcome is generally good.

Gastroesophageal reflux (GER), defined as passage of gastric contents into esophagus, and GER disease (GERD), defined as symptoms or complications of GER, are common pediatric problems encountered by both primary and specialty medical providers. Clinical manifestations of GERD in children include vomiting, poor weight gain, dysphagia, abdominal or substernal pain, esophagitis and respiratory disorders. On the other hand, recurrent vomiting is the symptom of hydronephrosis, brain tumor, food allergy, uremia, other metabolic disease, obstruction of intestine etc. It is very important for clinicians dealing with children and infants to understand GERD. The evaluation and treatment of gastroesophageal reflux in infants and children were reviewed here.

Headache is one of the common symptoms of fever and headache without fever is also not rare in general pediatric clinics. The common causes of these headaches involve extracranial infection due to viral illness, migraine and trauma. Headache with vomiting, fever and meningeal signs suggests meningitis. Taking blood pressure is necessary, even though headache caused by hypertension is rare in children. Neuroimaging should be performed with abnormal neurological findings, atypical headache pattern, or significant change of preexisting headache. Serious underlying diseases, such as brain tumor or intracranial hemorrhage, are uncommon, however they should be diagnosed immediately using neuroimaging because of their urgency.

We report a pediatric case of multiple sclerosis mimicking malignant brain tumor. A 11-year-old male presented with high fever, vomiting and partial convulsion of left lower extremity followed by left visual impairment. Magnetic resonance imaging (MRI) revealed a mass lesion in the right frontal lobe with significant peripheral edema. Incomplete ring-like enhancement by gadolinium administration was also noted. Open biopsy of the lesion was undertaken that provided pathological confirmation of demyelinating changes. Luxol fast blue stain and Bodian stain demonstrated extensive myelin loss and good preservation of axons. The patient was given intravenous high-dose methyl-prednisolone and sequential oral low-dose prednisone, which improved his neurological status progressively. The lesion was dramatically decreased in size and finally disappeared. Although many tumor-like demyelinating lesions were reported previously, pediatric cases of multiple sclerosis mimicking malignant brain tumor are extremely rare. Pathological examinations including Luxol fast blue stain and Bodian stain are essential for exact diagnosis.

Brain tumors represent around a quarter of all solid tumors observed in the pediatric population. Infratentorial tumors are the most frequent, mostly encountered between 4 and 11 years of age. Early imaging is important because initial symptoms can be misinterpreted as statural and pubertal disorders or pseudoabdominal symptoms with apathy and vomiting in infants. Because signal abnormalities on MRI are most often not specific, it is essential to take into account the clinical and topographic characteristics of the lesion to establish an appropriate differential diagnosis. The main patterns of brain tumors observed in pediatrics are presented. Brain metastases are very unusual in children, in contrast to lepto-meningeal metastasis.

Cancer in the central nervous system can arise from a primary brain tumor and metastasize to the brain or to the leptomeninges, leading to leptomeningeal metastasis (LM). LM also is called leptomeningeal carcinomatosis and carcinomatous meningitis. When LM occurs, signs and symptoms include headache, nausea, vomiting, lumbar back pain, and stiff or painful neck; LM also may lead to mental disturbances and seizures. Nursing care of patients with LM requires an understanding of neurologic anatomy and physiology, along with associated treatments and complications. Treatment of LM may involve intrathecal or, more likely, intraventricular chemotherapy. Very little has been written about appropriate care of patients with LM. The purpose of this article is to review the literature, summarize clinical care recommendations, and construct evidence-based guidelines for the administration of intraventricular chemotherapy and the care and monitoring of patients with LM.

Primary malignant brain tumors account for 2 percent of all cancers in U.S. adults. The most common malignant brain tumor is glioblastoma multiforme, and patients with this type of tumor have a poor prognosis. Previous exposure to high-dose ionizing radiation is the only proven environmental risk factor for a brain tumor. Primary brain tumors are classified based on their cellular origin and histologic appearance. Typical symptoms include persistent headache, seizures, nausea, vomiting, neurocognitive symptoms, and personality changes. A tumor can be identified using brain imaging, and the diagnosis is confirmed with histopathology. Any patient with chronic, persistent headache in association with protracted nausea, vomiting, seizures, change in headache pattern, neurologic symptoms, or positional worsening should be evaluated for a brain tumor. Magnetic resonance imaging is the preferred initial imaging study. A comprehensive neurosurgical evaluation is necessary to obtain tissue for diagnosis and for possible resection of the tumor. Primary brain tumors rarely metastasize outside the central nervous system, and there is no standard staging method. Surgical resection of the tumor is the mainstay of therapy. Postoperative radiation and chemotherapy have improved survival in patients with high-grade brain tumors. Recent developments in targeted chemotherapy provide novel treatment options for patients with tumor recurrence. Primary care physicians play an important role in the perioperative and supportive treatment of patients with primary brain tumors, including palliative care and symptom control.

We report a boy who in 1994, at the age of 11, presented with headache and vomiting. The fi nal diagnosis was papillary tumor of the pineal region (PTPR). Magnetic resonance imaging (MRI) revealed a heterogeneous mass. Hydrocephalus was addressed by immediate ventricle drainage; subsequently, we attempted tumor removal. As the intraoperative diagnosis of the hemorrhagic tumor was primitive neuroectodermal tumor (PNET), we did not proceed to total removal. After the delivery of radiotherapy (50.4 Gy) and one course of Nimustine hydrochloride (ACNU) chemotherapy, the residual tumor was completely resected. The diagnosis at that time (1994) was papillary pineocytoma. He was followed on an outpatient basis for 15 years and remained free of recurrence. This type of tumor was later proposed to represent a new distinct tumor subtype, papillary tumor of the pineal region (PTPR). Our data indicate that our patient's tumor should be included in this category.

To determine the safety and tolerability of IV and oral levetiracetam monotherapy for seizures in brain tumor patients following resection. Brain tumor patients undergoing neurosurgery with >or=1 seizure within the preceding month prior to surgery were enrolled to receive intravenous levetiracetam for a minimum of 48 h, transitioned to oral levetiracetam at the same dose, and followed for 1-month after discharge. Patients were assessed daily in the hospital, provided with a seizure diary, and supplied with 30 days of levetiracetam upon discharge. Study patients were telephoned weekly to assess their cognitive status and seizure frequency. Of the 17 patients enrolled, the baseline seizure types were tonic clonic, partial, and complex partial with secondary generalization. The most common type of tumor was glioblastoma multiforme. Levetiracetam was well tolerated with no medication discontinuation during the study period. Adverse effects reported were somnolence, nausea/vomiting, headache, and insomnia. Eleven patients were evaluable for TICS scores (64.7%) with an average score of 33.3. Two patients were deemed to be cognitively impaired (18.2%). Eleven of twelve patients (91.7%) that completed the study period achieved a >or=50% reduction in their number of seizures. A total of 92 drug interactions were avoided (P = 0.0016) with dexamethasone, acetaminophen, and fentanyl being the most common. Levetiracetam monotherapy was found to be safe and tolerable in this patient population. Nearly all patients achieved a >or=50% reduction in seizure frequency post-op with levetiracetam monotherapy. Levetiracetam also has the potential for less drug interactions compared to phenytoin in these patients.
