A 46-year-old woman, who had been treated with anti-arrhythmic drugs and digitalis for mitral stenosis and paroxysmal atrial fibrillation, suddenly developed severe abdominal pain and nausea. There was tenderness around right CVA. BUN and serum-creatinine were elevated, 57 mg/dl and 4.5 mg/dl respectively. She was in acute renal failure (ARF). WBC, GOT, GPT, LDH were also elevated. Abdominal ultrasonography showed normal-size right kidney (12 cm) and atrophic left kidney (8.5 cm). Selective right renal angiography revealed right renal arterial embolism, suggesting that ARF developed from right renal infarction complicated by left atrophic kidney. Renal scintigram using 99mTc-DTPA indicated non-function type left kidney. Because of the high risk of surgery, she received anticoagulant therapy. Fifteen days later, BUN and serum-creatinine returned to 14mg/dl, 2.2mg/dl, respectively.

To determine if carbohydrates perfused into the ileum affect gastric emptying and circulating levels of gastrointestinal hormones, 18 healthy subjects were intubated with an oroileal tube. A 400-cal (60% carbohydrate, 20% protein, 20% fat) homogenized meal labeled with 111In-DTPA was then infused into the stomach over 10 min. Simultaneously, a test solution of normal saline (n = 6) or 12.5 (n = 4), 25 (n = 4), 50 (n = 2), or 100 (n = 2) mg/min of carbohydrates (75% rice starch, 25% glucose) containing a nonabsorbable marker, polyethylene glycol, was continuously perfused into the terminal ileum at 3 ml/min for 7 h. In one-half of the subjects the perfusate contained an amylase inhibitor (3.3 mg/ml) that reduced starch digestion and carbohydrate absorption. Gastric emptying was measured by a dual-headed gamma-camera. Plasma concentrations of hormones and the amount of carbohydrates passing the ileum were measured every 10 min. The amylase inhibitor significantly reduced the absorption of complex carbohydrates from the terminal ileum (p less than 0.05). Gastric emptying was significantly slowed by ileal perfusion of carbohydrates (p less than 0.01). This effect was enhanced by the amylase inhibitor (p = 0.06). Plasma concentrations of C-peptide, glucagon, motilin, gastrin, and human pancreatic polypeptide were not related to gastric emptying or ileal perfusates, but decreased concentrations of gastric inhibitory polypeptide and neurotensin and increased concentrations of peptide YY were significantly associated (p less than 0.05) with slowing of gastric emptying. Perfusing carbohydrates into the ileum was associated with nausea, abdominal pain, and vomiting, but we could detect no direct relationship between the onset of these symptoms and gastric emptying. Slowing of gastric emptying of a homogenized mixed meal by the entry of complex carbohydrates into the ileum may be partly mediated by peptide YY or nonvagally mediated neural mechanisms.

In 9 out of 11 subjects with upper digestive dyspepsia: pyrosis, nausea, emesis, bloating, with negative roentgenological findings, a radioisotopic test detected a delayed gastric emptying. The investigation was based on a 500 ml saline meal including lmCi (3.7 MBq) 113m In-DTPA. For the sequential detection of the radioactivity in front of the epigastric area a gammacamera was used. This was linked to a microcomputer processing the histograms of the curves and estimating the half-time of the gastric emptying (normal value 8-25 min). The results suggest the need for prokinetic drugs in the management of symptoms due to functional pathology.

The development of new non-ionic magnetic resonance (MR) contrast media as gadodiamide injection increased the choice of paramagnetic contrast agents available in MR of the central nervous system (CNS). The purpose of our paper was to compare at the dose of 0.1 mmol/kg b.w. the safety of gadodiamide (Gd-DTPA-BMA) to gadopentetate dimeglumine (Gd-DTPA) and to gadoterate meglumine (Gd-DOTA) in two multicentric double-blind studies. A total of 551 patients were enrolled with 143 patients in the Gd-DTPA group, 132 patients in the Gd-DOTA group and 276 patients in the Gd-DTPA-BMA group. Safety was assessed by recording the adverse events up to 24 hours after the injection. One or more adverse events were recorded in 14% of the Gd-DTPA patients, in 15.1% of the Gd-DOTA patients and in 11.6% of the Gd-DTPA-BMA patients. These reactions were related to the contrast media in 9.1%, 13.6% and 8.7% of the cases respectively. Their intensity was defined as mild in 8.4% of the patients in the Gd-DTPA group, in 13.6% of the patients in the Gd-DOTA group and in 8.3% of the patients in the Gd-DTPA-BMA group. No severe reaction or death were recorded. An injection-site reaction (heat, coldness, pain) has been observed in 43% of the cases although an adverse event other than local reactions (headache, dizziness, nausea) has been noticed in 57% of the cases. No significant statistical difference was observed between the groups. Gadodiamide is a safe and effective contrast agent in MRI of the CNS in comparison with Gd-DTPA and Gd-DOTA currently in routine use.

Gadodiamide injection (Gd-DTPA-BMA) is a new non-ionic paramagnetic contrast agent for which the safety at the dose 0.1 mmol/kg was evaluated during a European multicentre study on a large population of adult patients who had an MR examination of the central nervous system with contrast medium. The safety analysis was performed on 2,102 patients by recording the adverse events observed during injection and up to 24 hours after the injection. Adverse events due or probably due to gadodiamide injection were observed in 102 patients (4.4%) with injection-site associated discomfort (heat, coldness, pain at the injection site) in 37 patients (1.8%) and adverse events other than discomfort (headache, nausea, vomiting) in 35 patients (3.1%). No adverse events of severe intensity or death were reported during the trial. Gadodiamide injection was shown to be safe and well tolerated and represents a non-ionic alternative to the current products in the field of MR imaging of the central nervous system.

A 57-year-old man was admitted because of headache, nausea, and fever up (38 degrees C). He showed nuchal rigidity slightly. CSF analysis showed 833 white blood cells (WBC) (80% monocyte), protein value of 68 mg/dl, glucose level of 36 mg/dl and ADA level of 11.8 IU/l. Brain pre-contrast CT indicated high density area in right parietal lobe, and it showed slightly homogeneously enhancement with contrast medium. MRI on T2 WI demonstrated hypointense lesion with bright central core in right parietal lobe. The lesion showed isointense on T1WI, and indicated homogeneous enhancement with Gd-DTPA. He was sent to our hospital after one week. With only antibiotics the symptoms were relieved and the CSF findings improved during the previous hospital. However, Mycobacterium tuberculosis (M. tuberculosis) DNA was detected in CSF by PCR amplification, and he recovered completely with anti-tuberculous treatment. This case was interesting to reveal atypical features of spontaneous recovery. Since Shankar's study using polymerase chain reaction (PCR) for detection of M. tuberculosis in cerebrospinal fluid (CSF), the PCR assay have been recognized to be a rapid method for diagnosis of tuberculous meningitis (TBM). But there are problems of PCR sensitivity when dealing with CSF samples containing small amount of M. tuberculosis DNA. Comparing direct PCR with nested PCR, we studied on the evaluation of PCR for diagnosis of TBM. In this study the nested PCR was positive in all CSF specimens from 4 patients with TBM, but we could not detect M. tuberculosis DNA by only the direct PCR. Nested PCR amplification improved the sensitivity and specificity.(ABSTRACT TRUNCATED AT 250 WORDS)

A 34-year-old woman was admitted to our hospital in 1991, because of progressive headache, nausea and generalized edema. She was diagnosed as Crow-Fukase syndrome associated with plasma cell dyscrasia (IgA lambda type) in 1987, presenting with polyneuropathy, edema, and dermatologic changes. Those manifestations were improved with irradiation and corticosteroids, but headache, nausea and generalized edema gradually developed after the discontinuation of corticosteroid therapy in 1991. On admission, marked bilateral papilledema was noted but fever and meningeal irritation signs were absent. A spinal tap showed a clear cerebrospinal fluid (CSF) with an open pressure of more than 400 mmH2O, normal cell count, total protein level of 87 mg/dl, and IgG level of 12.3 mg/dl. The CSF culture for microorganisms was negative and the cytological study of CSF also was normal. De novo synthesis rate of CSF IgG was markedly elevated (35.3 mg/day). MRI of the head using Gd-DTPA revealed diffuse hypertrophic dura mater, which made the diagnosis of chronic pachymeningitis. Cerebral angiographies were normal. An RI cisternography demonstrated delayed absorption of the CSF without ventricular reflux. Gallium and bone scintigrams did not show any pathological accumulation of the isotopes in the head. The lack of abnormalities causing chronic pachymeningitis in this case suggests that the chronic pachymeningitis might be associated with Crow-Fukase syndrome. The development of increased intracranial pressure is not rare in Crow-Fukase syndrome but the etiology remained unknown in most cases. We therefore suggest that MRI study with contrast enhancement should be performed in cases of this condition with increased intracranial pressure.

Seventy-nine patients with known or suspected central nervous system lesions were studied with MRI in a phase III double-blind study. Forty were given gadopentetate dimeglumine (Gd-DTPA) and 39 gadodiamide injection (Gd-DTPA BMA), a new low-osmolar nonionic contrast enhancing medium. The dosage was 0.1 mmol/kg body weight, corresponding to 0.2 ml/kg. Spin-echo sequences were performed before and immediately after injection. The safety and efficacy of the two contrast media were assessed. No changes were observed in blood pressure, heart rate or neurological status. Five adverse effects (two episodes of headaches, two of nausea and one of dizziness) were reported by 2 patients who received gadodiamide injection and 1 who received gadopentetate dimeglumine. All events were mild and their relationship to the contrast media was uncertain. For both contrast media statistically significant changes in serum iron were observed 24 h after injection. More than 70% of the patients had abnormal findings on MRI, and in 56% of these contrast enhancement of the abnormal structure or lesion was seen. Contrast enhancement provided the diagnosis in about 50%, changed it in 40% and increased diagnostic confidence in 95%.

We reported two early-childhood cases suffering from acute optic neuritis (ON). Case 1 was a 3-year-old girl, who had a preceding upper respiratory infection, headache, nausea and subsequent sudden visual disturbance. Cranial MRI revealed multiple T2-elongated lesions in the white matter. She showed two neurological relapses including ON, leading to the diagnosis of clinically probable multiple sclerosis (MS). Case 2 was a 2-year-old boy, who had an acute onset of visual disturbance without any other neurological deficits. MRI with Gd-DTPA enhancement revealed not only a disorder of optic nerves but involvement of the white matter in the acute phase. It has been suggested that there may be a broad spectrum of demyelinating disorders between ON and MS even in early-childhood. Therefore, we should bear in mind to the subsequent progression to MS in childhood ON cases with silent brain lesions.

Magnetic Resonance Imaging (MRI) is considered a useful procedure for evaluating the intracranial diseases. Leukemic infiltration in either the oculomotor or trigeminal nerve is rarely seen by MRI. We herein describe the diagnostic assessment and outcome of an adult patient suffering from acute lymphoblastic leukemia (L2, FAB). An 18-year-old female was suspected to have ALL. She complained of nausea, vomiting, and double vision for a month, and further examination was required. Fiber gastroscope examination revealed no abnormal lesions in the upper gastrointestinal tract. Furthermore, a plain brain CT indicated no abnormalities in the brain. However, examination of a Gd-DTPA enhanced MRI and the liquor revealed that she had leptomeningeal leukemia with oculomotor and trigeminal nerve infiltration. Systemic administration of methotrexate (MTX) and cytarabine, and intrathecal injection of MTX were partially effective. Repeated Gd-DTPA enhanced MRI showed the shrinkage and reduced enhancement of oculomotor and trigeminal nerve, parallel to the improvement in the liquor. This case demonstrates the importance of MRI not only in the evaluation of therapy, but also in the early diagnosis of central nervous system leukemia.
