Seasonal and climatic variations have been linked to the occurrence of some types of cerebrovascular disease. However, the conditions that lead to intracranial aneurysm rupture are not known. The purpose of the present study was to determine whether predisposing factors are more related to intracranial aneurysm rupture and to determine relation of the stressful condition to intracranial aneurysm rupture. In order to determine the predisposing factors, the authors have examined the relationship between seasonal variation and predisposing factors of cerebral aneurysm. The author investigated activities of the patients and events as well as diurnal and seasonal variations in the onset of subarachnoid hemorrhage(SAH) in 336 consecutive patients. The results showed that the onset of SAH was associated with working in 11.0%, defecation and/or urination in 8.3%, sleeping in 6.9% and 4.2% walking. Hypertensive patients in aneurysmal rupture was 36.0%. Subarachnoid hemorrhage occurred during stressful events in 36.3% of the patients, during nonstreneous events in 34.8% and during rest or sleep in 9.8%. The activities or events preceding subarachnoid hemorrhage were not known in the remaining 18.8%. Men were more likely to have suffered their hemorrhages during stressful events than women(47% vs 30%). Peak times of intracranial aneurysm rupture usually occurred from 6 to 11 A.M.(36.0%) and from 4 to 6 P.M.(20.5%). The seasonal variation of the onset of SAH showed the incidence to be slightly higher in winter than in any other seasons. We concluded that the occurrence of subarachnoid hemorrhage display seasonal and diurnal variation. And the precipitation of aneurysmal rupture have two important factors; increased arterial blood pressure and decreased cerebrospinal fluid pressure around the aneurysm. Also, the onset of the subarachnoid hemorrhage is related to the physiological circadian periodicity of blood pressure, climatic change and stressful events.

Microcystic meningioma, a distinct morphological variant of meningiomas, is histologically characterized by a vacuolated appearance with multiple cystic spaces lined by vacuolated or stellate-shaped tumor cells. This unusual variant was originally described by Masson, who labeled it "humid". The clinical and morphological findings point toward a benign course. And these unusual morphological variants of meningioma are potentially curable tumor. But there is no definitive method for preoperatively differentiating microcystic meningioma from the malignant glioma. We report a case of microcystic meningioma occurring in the left frontal area of 74 year old woman, with malignant clinical nature.

BACKGROUND: Urinary bladder cancer has been diagnosed by urine cytology and cystoscopy with biopsy. Recently, in vitro noninvasive diagnostic tests, measuring urinary nuclear matrix protein22(NMP22) and bladder tumor antigen(BTA), were introduced. We analyzed the usefulness of the NMP22 and BTA tests for diagnosing bladder cancer and compared those with voided urine cytology. MATERIALS AND METHODS: Single voided urine specimens were obtained from 27 patients with bladder cancer and 23 healthy volunteers. The urine specimens were assayed by enzyme immunoassay(NMP22, Matrietech(R), Newton, MA.) and latex immunoassay(BTA, Bard, USA). Urine cytology was performed in patients with bladder cancer. RESULTS: Mean urinary NMP22 level of patients with bladder cancer(144.6 U/mL) was significantly higher than those of normal controls(2.9 U/mL, P<0.01). The sensitivities were 89% and 74% for NMP22 and BTA tests, respectively, compared with 41% for voided urine cytology. The sensitivities of NMP22 and BTA tests were 88%, 63% at grade 1(G1), 82%, 73% at G2, and 100%, 88% at G3, respectively(P<0.01; NMP22, P=0.580; BTA). According to tumor stage, the sensitivities of NMP22 and BTA tests were both 79% at superficial, and 100% and 69% at invasive cancer, respectively(P=0.110; NMP22, P=0.678; BTA). The sensitivities of urine NMP22 and BTA tests combined with urine cytology were both 96%. In following of transitional cell carcinoma patients, agreement between urine cytology and BTA test was 75%(24/32). Among the various urologic disease, false positive rate for BTA test was 17%(8/47). CONCLUSION: Urinary NMP22 and BTA tests were more sensitive than voided urine cytology regardless of tumor grade and stage, so these noninvasive and simple tests can be used as screening tests for urinary bladder transitional cell carcinoma.

Cytomegalovirus (CMV) infection is more frequent in immunocompromised patients those with acquired immunodeficiency syndrome (AIDS), malignant disease, steroid therapy. However, CMV can infect a healthy person who has normal immunity. Most cases of CMV infections are due to reactivation of latent virus. We report a case of cytomegalovirus colitis in a 73 years old woman who has congestive heart failure with normal immunity. Sigmidoscopy reveals cobble stone like mucosa and deep ulceration. CMV infection produces a cytomegalic cell containing a intranuclear inclusion, which is surrounded by clear halo in Hematoxylin-Eosin stain. Immunohistochemical stain for CMV reveals focal positive in cytoplasm and in nuclei of large cells. We diagnosed CMV colitis with histopathologic finding and immunohistochemistry through sigmoidoscopic mucosal biopsy.

PURPOSE: To report a case of bilateral Coats' disease. CASE SUMMARY: A 19-month-old boy presented with esodeviation of his eyes, which started 5 months prior. A fundus exam showed total bullous exudative retinal detachment with retinal vascular telangiectasia in the right eye and localized exudative retinal detachment with vascular telangiectasia at the inferior periphery in the right eye. Fluorescein angiogram of the left eye showed retinal telangiectatic vessels, avascular area and fluorescein leakeage from telangiectatic vessels. The patient received external drainage of subretinal fluid and intravitreal air injection of the right eye and Argon LASER photocoagulation and cryotheraphy of the left eye. A cytologic exam of the subretinal fluid drained from the right eye showed no malignant cells. Forty-four months after the operation, his best corrected visual acuity was no light perception in the right eye and 0.4 in the left eye. Both fundi were flat and stable. No complications, such as glaucoma, recurred retinal detachment, or pain, occurred. CONCLUSIONS: Coats' disease rarely occurs bilaterally and can be involved asymmetrically. The disease presents more severely when bilateral and can progress after long-term observation. Proper treatment and long-term follow-up of both eyes are necessary to prevent visual loss and preserve eyes.

A nasal provocation test is the most reliable diagnostic test to confirm allergen in allergic rhinitis. However, there are neither specific objective methods nor a standardized method and interpretation. In 20 normal subjects and 86 allergic rhinitis patients, we applied acoustic rhinometry as a new objective method to assess changes in nasal patency induced by nasal allergen challenge, a procedure which is used for confirming allergic rhinitis. The result shows that a minimal cross-sectional area (MCA) and volume from the nose tip on back to 7 cm (nasal cavity volume) after allergen challenge were significantly decreased in allergic rhinitis patients in comparison with the control subjects. We conclude that acoustic rhinometry can provide a sensitive index for evaluating the results of a nasal provocation test.
