Spontaneous intracranial hypotension (SIH) is typically manifested by orthostatic headaches that may be associated with one or more of several other symptoms, including pain or stiffness of the neck, nausea, emesis, horizontal diplopia, dizziness, change in hearing, visual blurring or visual field cuts, photophobia, interscapular pain, and occasionally face numbness or weakness or radicular upper-limb symptoms. Cerebrospinal fluid (CSF) pressures, by definition, are quite low. SIH almost invariably results from a spontaneous CSF leak. Only very infrequently is this leak at the skull base (cribriform plate). In the overwhelming majority of patients, the leak is at the level of the spine, particularly the thoracic spine and cervicothoracic junction. Sometimes, documented leaks and typical clinical and imaging findings of SIH are associated with CSF pressures that are consistently within limits of normal. Magnetic resonance imaging of the head typically shows diffuse pachymeningeal gadolinium enhancement, often with imaging evidence of sinking of the brain, and less frequently with subdural fluid collections, engorged cerebral venous sinuses, enlarged pituitary gland, or decreased size of the ventricles. Radioisotope cisternography typically shows absence of activity over the cerebral convexities, even at 24 or 48 hours, and early appearance of activity in the kidneys and urinary bladder, and may sometimes reveal the level of the leak. Although various treatment modalities have been implemented, epidural blood patch is probably the treatment of choice in patients who have failed an initial trial of conservative management. When adequate trials of epidural blood patches fail, surgery can offer encouraging results in selected cases in which the site of the leak has been identified. Some of the spontaneous CSF leaks are related to weakness of the meningeal sac, likely in connection with a connective tissue abnormality.

The FDA has approved amprenavir (Agenerase), the fifth protease inhibitor (PI) to be approved and the first PI approved in 2 years. When used in triple combination therapy, amprenavir is effective in viral suppression in treatment-naive patients and some patients who have taken NRTIs and NNRTIs. The drug has also been shown to be effective in about half of the patients who are resistant to other PIs. The standard dose for amprenavir is eight large capsules taken twice a day. Levels of amprenavir may be affected by the concurrent use with efavirenz (Sustiva). Common side effects of amprenavir include nausea, vomiting, diarrhea, and numbness and tingling around the mouth.

The authors describe 2 cases of posterior fosa venous infarction. A 56-year-old woman with essential thrombocytemia presented with fluctuating complaints of headache, nausea, vomiting, left-sided numbness-weakness, and dizziness and became progressively stuporous. Cranial magnetic resonance imaging (MRI) showed bilateral parasagittal fronto-parietal and left cerebellar contrast-enhancing hemorrhagic lesions. On magnetic resonance venography, the left transverse and sigmoid sinuses were occluded. The second patient, a 39-year-old woman, presented with acute onset of diplopia, numbness of the tongue, vertigo, and right-sided weakness following a gestational age stillbirth. MRI revealed lesions in the right half of midbrain and pons and in the superior part of the right cerebellar hemisphere. Digital subtraction angiography showed right transverse and sigmoid sinus occlusion. The authors suggest that one should investigate the possibility of venous infarction in the presence of posterior fossa lesions that are often hemorrhagic and are not within any arterial territory distribution but respect a known venous drainage pattern. Recognition of the observed clinical and neuroimaging features can lead to earlier diagnosis and, potentially, more effective management.

We evaluated the efficacy and safety of ondansetron hydrochloride (OND) on nausea and vomiting during repeated courses of CHOP or ACOMP-B therapy in patients with malignant lymphoma. The impact of the prognosis announcement on the anti-emetic effect and chemotherapy-associated adverse events was also investigated. Forty-two subjects with malignant lymphoma who underwent CHOP or ACOMP-B therapy including cyclophosphamide 600 mg/m2 and adriamycin 40 mg/m2 were investigated for a maximum of 6 courses. For acute nausea and vomiting, ondansetron was injected intravenously before the start of chemotherapy on the first day of each course of chemotherapy. For delayed emesis, ondansetron was administered orally for 4 days from the following day. The efficacy on acute nausea and vomiting was found to be 95.0% (1st course), 95.0% (2nd course), 90.9% (3rd course), 88.2% (4th course), 92.3% (5th course) and 91.7% (6th course), respectively. A high efficacy of > or = 85% was also obtained for delayed nausea and vomiting on each day. Though the adverse event of elevated GPT value developed in one subject. It was mild and resolved. No difference in efficacy was seen with or without announcement of prognosis to patients. Following the investigation on antiemetic effect, patient perception of chemotherapy-induced adverse events was evaluated. The most common event was hair loss, followed by taste abnormality and numbness and hyposthesia of the tips of the fingers. The incidence of nausea and vomiting was the 4th and 5th most common, which are less frequent than in the report of Coates in 1983. In conclusion, ondansetron is considered clinically useful with stable anti-emetic effect on both acute and delayed nausea and vomiting over repeated courses of chemotherapy, without any significant safety problem.

Some plants contain glycoside compounds which determine cardiovascular symptoms similar to those observed after acute toxic digoxin administration. The present case report involves a patient who showed important cardiovascular symptoms following the ingestion of Thevetia nereifolia/peruviana seeds. About 30 min after ingestion, a 65-year-old man presented with dizziness, giddiness, numbness and a burning sensation, diarrhea, sweating, vomiting and ECG changes. At the time of admission he presented with tremors; his body temperature was 37 degrees C, and blood analysis gave the following results: K 5.6 mEq/l, myoglobin 176 IU, troponin T 0.10 ng/ml, PO2 69 mmHg, PCO2 37.4 mmHg, pH 7.33, HCO3- 19.9 mEq/l, hemoglobin 14.8 g/dl, saturation 92.5%. Echocardiography showed a left ventricle with normal global and segmentary contractility. The following days, the patient showed a reduction, until total resolution, of the atrioventricular block and of the alterations of the ST segment. The ectopic beats also resolved; K value before discharge was 4.4 mEq/l. On the third day, the serum levels of digoxin were 0.15 ng/ml. This case report is important because it describes all the cardiovascular and non-cardiovascular signs of glycoside toxicity in an adult patient who accidentally swallowed only two seeds (non-fatal dose) of Thevetia.

We report here a case of a patient with a dissecting aneurysm of the anterior medullary segment of the posterior inferior cerebellar artery (PICA) which presented with Wallenberg's syndrome. A 32-year-male presented with an unusual case of Wallenberg's syndrome due to a dissecting aneurysm of the PICA manifesting as a sensation of heaviness in the occipital region and vertigo. The occipital symptoms persisted and vertigo and vomiting developed after 6 days. Numbness developed on the left side of the patient's face, and hyperalgesia on the right side of the body. The diagnosis of Wallenberg's syndrome was based on the above findings. MRI revealed infarction of the lateral aspect of the medulla oblongata and MR angiography revealed dilatation in the proximal portion of the left PICA. Digital subtraction angiography revealed that the left vertebral artery was essentially normal, but there was a spindle-shaped dilatation in the proximal portion of the left PICA. We carried out conservative therapy at the patient's request and 3D-CTA revealed that the dissecting aneurysm was markedly reduced in size seven months after the onset. Dissecting aneurysms of the intracranial posterior circulation have been shown to be less uncommon than previously thought. However, those involving the PICA without involvement of the vertebral artery at all are extremely rare. The natural history of the dissecting PICA aneurysm was unknown, and the indication for surgical treatment of such aneurysms remains controversial. Management options are conservative treatment, open surgical treatment including wrapping, trapping, and resection with reconstruction, but almost all of the patients underwent radical treatment to prevent rupture of the aneurysm. However we had no knowledge of the risk of rupture of a PICA dissecting aneurysm presenting with ischemic symptoms. We have reviewed the well-documented 15 cases of dissecting aneurysms of the PICA reported in the literature and we discuss the management of the dissecting PICA aneurysm presenting with ischemic symptoms.

Rhombencephalitis due to listeria monocytogenes is an uncommon and serious form of brainstem infection. The disease has a characteristic biphasic course: a nonspecific prodrome of headache, nausea or vomiting, and fever lasting for a several days is followed by progressive asymmetrical cranial-nerve palsies. We report two cases of Listeria monocytogenes rhombencephalitis. The first case is a previously healthy 20 year-old-man who developed fever, headache, nausea and vomiting, followed by numbness in left trigeminal nerve. The second case is an immunosuppressed 77 year-old-man, who developed sudden left hemiparesis, followed by fever and severe brainstem dysfunction with ophthalmoplegia and dysphagia. In both cases, a brain magnetic resonance imaging (MRI) scan, showed increased intensity on T2-weighted lesions in the brainstem that enhanced after contrast on T1-weighted sequences. Both patients had a favorable outcome with full clinical recovery. We conclude that MRI aids in the early detection of parenchymal infections, therefore, MRI is crucial for early diagnosis and is very useful for follow-up examinations.

The aim of our study was to evaluate and compare the therapeutic efficacy & safety profile of three different antituberculous regimens for pulmonary tuberculosis. The study sample size included 90 newly diagnosed, sputum positive patients of pulmonary. tuberculosis. 30 each from different groups. The parameters studied were, therapeutic efficacy included weight gain, cough, sputum examination and safety profile: nausea, vomiting, anorexia, gastritis, hepatitis, jaundice diarrhoea, rashes, dizziness, tingling & numbness, flu like symptoms & joint aches. Group-I showed statistically significant weight gain when compared to Group-II. Improvement in cough and conversion to smear negative were seen in 100% of patients in Group-I, 83.3% of patients in Group-II and 93.3% of patients in Group-III. Therapeutic efficacy was highest with Group I regimen, followed by Group III and Group II which was least efficacious. Group II also registered; the maximum cost and highest incidence of adverse effects.

We examined the clinical symptoms and laboratory findings of 21 children with aseptic meningitis caused by echovirus 13 during the summer of 2002. All patients (mean age: 8.3 years) complained of fever and headache. Some had mild vomiting and some had severe vomiting of 4 times or more. In the early stage of the disease, the mean count of WBC was 8,283/microliter, mean level of CRP was 0.8 mg/dl, and there were no abnormalities in levels of GOT, GPT, or LDH. The levels of protein and sugar, in cerebrospinal fluid showed no abnormalities, and mean total cell count was 560/microliter. The mean number of polynuclear cells was 357/microliter, and of mononuclear cells was 203/microliter, showing polynuclear cell predominance. In the recovery period, the tendency to polynuclear cell predominance in the early stage of the disease shifted to mononuclear predominance. One of the 21 patients exhibited multinucleated cell predominance in the cerebrospinal fluid, a high CRP value of 6.2 mg/dl, as well as symptoms of restlessness including numbness of the limbs, hyperpnea, and excitation, needed careful diagnosis as aseptic meningitis. Almost all of the patients were mild cases, and no large differences were seen with the clinical and laboratory findings in previous reports of echovirus aseptic meningitis.
