A 58-year-old male suffered a massive intratumoral hemorrhage after placement of a ventriculoperitoneal shunt before treatment for pineocytoma. At admission, he complained of headache, urinary incontinence, gait disturbance, and recent memory disturbance. His neurological examination revealed impaired memory and papilledema from hydrocephalus. Two days after the placement of the ventriculoperitoneal shunt, he suddenly became stuporous and Parinaud's sign appeared. Computed tomography showed a massive intratumoral hemorrhage occupying the third ventricle which had extended into the lateral ventricle. The infratentorial supracerebellar approach was used to remove the hematoma and the tumor. The histological diagnosis was pineocytoma. Intratumoral hemorrhage in pineocytoma after the placement of a ventriculoperitoneal shunt is rare, but should be kept in mind when a ventriculoperitoneal shunt is placed before a craniotomy.

Menopause and the accompanying reduction in estrogen production may cause a number of symptoms in women which include hot flushes, sweating, mood and sleep disturbances, fatigue and urogenital dysfunction. The effectiveness of estrogen-based hormone replacement therapy (HRT) in ameliorating these symptoms, and in preventing long term sequelae such as osteoporosis, is well established. Comparative trials indicate that oral conjugated estrogens 0.625mg, oral ethinyl estradiol 0.02mg and transdermal estradiol 0.05mg have equivalent efficacy in relief of mild to moderate menopausal symptoms and prevention of bone mineral loss. Concomitant progestogen therapy is usually prescribed for women with intact uteri to protect against endometrial hyperplasia and carcinoma. The addition of progestogen maintains and may even enhance the bone-conserving effects of estrogen, and continuous regimens appear to reduce the incidence of irregular menses. Adverse reactions are predominantly local skin irritation with transdermal preparations (14% of patients) and systemic effects common to most forms of HRT including breast tenderness, flushing, headache and irregular bleeding, occurring in less than or equal to 2% of patients. Data concerning the effect of HRT on quality of life are limited, but most analyses have assigned utility values of 0.99 for mild and 0.95 for severe menopausal symptoms. However, recent clinical data suggest that these utility values may underestimate the impact of menopausal symptoms on quality of life. The cost benefit and cost effectiveness of HRT in the treatment of menopausal symptoms have not been fully researched, although preliminary results suggest that conjugated estrogens and transdermal estradiol compare well with alternative therapies such as veralipride and Chinese medicines. A Swedish study using a prevalence-based approach estimated that estriol treatment in all women with urinary incontinence aged greater than or equal to 65 years resulted in monetary savings compared with treating 20% of women. Cost-utility data indicated that the change in quality-adjusted life years (QALYs) with HRT was always positive, but the degree of change was determined by the baseline assumptions. Estimated changes in QALYs with HRT ranged from 0.006 for 5 years of treatment with unopposed estrogen in women with intact uteri, to 0.5 for 10 years of the same treatment in women with severe menopausal symptoms following hysterectomy. Compliance with HRT is suboptimal as 5 to 50% of women withdraw from therapy, thereby increasing costs per year of life saved.(ABSTRACT TRUNCATED AT 400 WORDS)

Chemotherapy for malignant brain tumors has a limited efficacy largely due to restricted blood-brain barrier permeability for chemotherapeutic drugs. Intraarterial chemotherapy (IAC) has the advantage of increased uptake during the first passage of the drugs through tumor capillaries. Initial IAC trials had less than satisfactory results due to unacceptable toxicities. Between 1987 and 1996, 173 patients with primary and metastatic brain tumors were treated with intraarterial (intracarotid and/or intravertebral) cisplatin and etoposide (VP-16). Out of these, 168 patients, who received a total of 438 cycles, were evaluated for the incidence of toxicities. Patients received either cisplatin at 40 mg/m2 and VP-16 at 20 mg/m2 or cisplatin at 60 mg/m2 and VP-16 at 40 mg/m2. Nausea and vomiting were the most common toxicities (42 patients, 14% of cycles). Arterial puncture was associated with a 1.6% incidence of groin hematomas (6 patients), and a 0.7% incidence of failure to canulate the carotid or vertebral arteries (3 patients). Neurologic toxicities included headache (1.4% of cycles, 5 patients), focal seizures (1.4% of cycles, 5 patients), transient confusion and urinary retention/incontinence (1.9% of cycles, 8 patients), and blurred vision (0.9% of cycles, 4 patients). We have not seen visual loss, strokes, major vessel dissection or thrombosis, or myelosuppression. Toxicity incidence was higher in patients with metastatic brain tumors than in those with primary brain tumors (34% versus 17%, p < 0.001). It was also higher in patients who had brain radiation therapy (RT) prior to IAC than in those who had RT concomitant with IAC (31% versus 19%, p = 0.05). No significant difference in toxicity incidence was noticed between patients who received RT concomitant with IAC and those who received RT after IAC (19% and 23% respectively, p = 0.08). Intracarotid chemotherapy given prior to RT resulted in 23 months of median survival for patients with glioblastoma multiforme. Intraarterial chemotherapy with cisplatin and VP-16 is a relatively safe treatment modality, especially in patients with primary brain tumors who have not received brain radiotherapy.

Detrusor instability, or urinary incontinence, is common in elderly patients, particularly elderly women. The clinical symptoms of overactive, or unstable, urinary bladder include urge urinary incontinence, urgency, and frequency. Mixed urinary incontinence, which comprises urge urinary incontinence and stress incontinence, is manifested by increased intraabdominal pressure on coughing or sneezing. The detrusor muscle of the bladder is under the control of the parasympathetic, or muscarinic, nervous system. The drug of choice in this condition is oxybutynin chloride, which has the ability to block acetylcholine released from parasympathetic nerves in the urinary bladder, preventing contractions of the muscle and exerting a direct spasmolytic effect on the bladder. A new extended-release oral tablet formulation, OROS oxybutynin, uses osmotic pressure to deliver the drug at a controlled rate over approximately 24 hours. It resembles a conventional tablet but has a two-part core consisting of a drug layer and below it, a "push" layer containing osmotically active components, the whole surrounded by a semipermeable membrane with a laser-drilled opening in the drug side. Water in the gastrointestinal tract enters the tablet and mixes with the drug to form a suspension. The "push" layer expands and pushes the suspended drug out of the orifice and into the gastrointestinal tract for eventual absorption. Pharmacokinetic studies have indicated a slow rise in mean plasma concentration of the isomer R-oxybutynin for 4 to 6 hours after a single dose of OROS oxybutynin, followed by maintenance of steady concentrations for up to 24 hours, minimizing the fluctuations between peak and trough associated with TID dosing of 5-mg immediate-release oxybutynin tablets. Efficacy and safety studies comparing the extended-release with the immediate-release formulation of oxybutynin demonstrated equivalent efficacy in patients with overactive urinary bladder. The adverse-event profile of oxybutynin is similar to that of a typical anticholinergic agent such as atropine--dry mouth, constipation, somnolence, blurred vision, headache, and gastrointestinal pain--although in 2 clinical studies, the incidence of dry mouth was less with the extended-release formulation. Once-daily dosing with OROS oxybutynin appears to be well tolerated and effective, as well as convenient, for the treatment of overactive bladder, particularly for elderly patients using multiple medications.

A 51-year-old man suffered from impotence for 10 months. Five months before he developed difficulty in urination and walking because of his both leg weakness. He was admitted to the hospital because of urinary incontinence, paraplegia and occipital headache. Neurologic examination revealed neck stiffness and Lhermitte's sign. The cranial nerves were intact with the exception of choked disc. He had weakness of lower extremities and right arm, and sensory loss on the right side including face. The plantar responses were extensor bilaterally. MR images revealed diffuse swelling in the cervical and thoracic spinal cord on a T 1-weighted image without enhancement by Gd-DTPA and diffuse high intensity of the spinal cord on a T 2-weighted image. MR image of the brain revealed the low intensity in the left temporal and occipital lobe with slightly enhancement by Gd-DTPA, the high intensity in the left temporal and occipital lobe white matter on a T 2-weighted image. Diagnosis of malignant lymphoma (B cell type) was made by brain biopsy. Combined chemotherapy was performed and his symptoms resolved and the lesions on MRI disappeared. The number of cases of primary spinal intramedullary malignant lymphoma was very rare and the majority of the cases had weakness or sensory impairment in the lower extremities in the initial symptoms. This is the first case which had impotence as the initial symptom. In addition, it must be taken into consideration of this disease when the patient has myelopathy with unknown etiology.

Three cases of chronic subdural hematoma (CSH) associated with malignancy are reported. Case 1; A one-year-old girl was referred for vomiting and convulsions. Left CSH was removed, and her symptoms disappeared. Cytological examination of chronic subdural hematoma revealed abnormal white blood cells. A clinical diagnosis of acute monocytic leukemia was made after the laboratory examination. Remission was achieved by chemotherapy, but she died one year after the operation. Case 2; A 72-year-old woman was referred for right hemiparesis and urinary incontinence. Left CSH was irrigated, and her clinical symptoms immediately disappeared. Cytological examination of chronic subdural hematoma revealed abnormal white blood cells. A clinical diagnosis of chronic lymphocytic leukemia was made after the laboratory examination. No treatment was given since there were no clinical symptoms of chronic lymphocytic leukemia. Case 3; A 70-year-old woman who had been affected with early gastric cancer and mammary cancer for the previous two years was admitted to our clinic because of headache, right hemiparesis and consciousness disturbance. Left CSH was irrigated, and her clinical symptoms improved. However, there was a tendency to bleed because disseminated intravascular coagulation had occurred, and CT showed bilateral subdural hematoma. A second irrigation was performed, but her symptoms did not improve. Left acute subdural hematoma, which was removed by craniotomy, occurred three days after the second operation. Pathological examination of the outer membrane of the subdural hematoma revealed invasion of adenocarcinoma. She died three days after the third operation. It is recommended that both the cytological and the histological examinations be performed when possible, since they are simple to perform and very useful in some cases.

Tuberculous meningitis, while not uncommon in Taiwan, has not been reported among foreign workers. We report the first case of tuberculous meningitis in a 37-year-old Filipino maid in Taiwan, who presented with headache, fever and vomiting. She had been well before this episode and the small screening films of the chest radiograph obtained on her arrival in Taiwan 15 months previously, and every 6 months thereafter showed no evidence of tuberculosis. The suspicion of tuberculous meningitis was delayed until disturbance of consciousness manifested and a standard chest radiograph showed a diffuse miliary pattern in both lung fields. A cerebrospinal fluid sample that was sent for a polymerase chain reaction-based assay specific for Mycobacterium tuberculosis showed a positive result. The patient recovered with sequelae of mildly incoherent speech and urinary incontinence after antituberculous medication and short-course steroid treatment. Clinicians should be aware of the possibility of tuberculous meningitis in foreign workers with complaints of fever and headache. Because high-quality chest radiographs are a prerequisite for early detection of pulmonary tuberculosis, we recommended that standard posterior-anterior chest radiographs should be obtained as part of the routine health examination for foreign workers.

A 6-year-old female patient with acute disseminated encephalomyelitis associated with poliomyelitis vaccine virus is reported. She had a history of high fever, headache, and gait disturbance. Neurologic examination confirmed spastic triparesis, urinary incontinence, diminution of tactile sensation, and vision deterioration. Hemography, serum laboratory findings, and urinalysis were normal. The cerebrospinal fluid was clear, with normal pressure, 9 leukocytes/mm(3), and 27 mg/dL protein, but the myelin basic protein was elevated to 10.7 ng/mL. T(2)-weighted magnetic resonance imaging disclosed multifocal high-intensity lesions of the spinal cord. The serum polio virus type 2 antibody titer was raised in the acute phase, and polio vaccine virus type 2 was detected in viral cultures of the cerebrospinal fluid and pharynx swab and had undergone an A-G neurovirulence mutation at nucleotide 481. Finally, she had human leukocyte antigen (HLA)-Cw3 and HLA-DR2, to which multiple sclerosis is related in Japan. Thus the cause of ADEM may have been related to her HLA type.

A woman admitted with psychotic depression developed a number of physical problems. Urinary incontinence, headache, neck stiffness and breathing difficulties were all treated separately but were later found to be part of the neuroleptic malignant syndrome. Treatment of the disorder led to complete recovery. We review the criteria for diagnosis of this serious disorder and some differential diagnoses.

A 53-year-old woman was admitted to the hospital because of headache and disturbance of consciousness. She was afebrile. No inflammatory reaction was identified on serologic examination. Radiological findings showed acute-subacute, massive intracerebral hemorrhage in the right temporal lobe, compressing the brain stem contra-laterally. On the day of admission, she underwent a right temporal craniotomy for the removal of the mass lesion. The resected brain tissue demonstrated a small hemorrhage and edema accompanied by the infiltration of lymphoid cells into the subarachnoid space. Several days after surgery, the patient became lethargic and showed urinary incontinence. Late onset of fever and CSF findings suggested she was suffering from viral encephalitis. Serological findings, however, disclosed no antibody production against HSV, HZV, or CMV. For the diagnosis, a biopsy of the brain was carried out and herpes encephalitis was subsequently proved. Unfortunately, her condition deteriorated quickly and she died without anti-viral treatment.
