Aqueductal forking was first described by Russell (l949) as a cause of aqueductal obstruction and a form of congenital malformation with simple stenosis, it is a relatively common cause of congenital hydrocephalus not associated with spina bifida or meningomyelocele. Pathologically it is characterized by two distinct channels separated by non-gliotic brain tissue. We describe variable clinicopathologic findings of 3 autopsy cases showing hydrocephaly due to aqueductal atresia with forking case 1 was a 35-week-old female showing Potter's syndrome, dextrocardia, and skeletal anomaly. case 2 was a 29-week-old male abortus with micrognathia, simian crease, club feet, and minor defects of visceral organs. Case 3 was a 32-week-old female abortus with associated anomalies such as a low-set ear, ectopic thymus and thyroid, and Meckel's diverticulum. On serial sections of brain stems of all 3 cases, were seen variably shaped and atretic lumina of aqueducts with distinct two channe1s and intervening brain tissues of normal cellularity.

Recently, we have experienced case of juxtapapillary retinal angioma. This patient was a 32-year-old Korean woman who visited our hospital because of blurred vision in her left eye for about 20 days. At the time of examination, the visual acuity of this eye was 0.3. Ophthalmoscopic examination revealed a sherical, highly vascularized tumor at the temporal margin of the optic papilla and peripapillary retinal exudates. This case was presented with a brief review of the literature.

PURPOSE: This study was to identify the effects of hope intervention on the hope and quality of life of cancer patients staying at home. METHOD: The study adopted the randomized control group design. The subjects consisted of randomly selected forty cancer patients who were registered at S-Gu Public Health Center. Hope intervention which was composed of hope assessment, positive self identity formation, hope objective setting, therapeutic relationship and spiritual & transcendental process improving, and hope evaluation was provided from October 22, 2007 to November 30, 2007. RESULT: Hypothesis 1-1 "The experimental group that received hope intervention will have a higher score of hope than the control group", was supported(t=-3.108, p=.004). Hypothesis 1-2 "The experimental group that received hope intervention will have a higher level of hope index than the control group", was supported (t=-4.219, p=.000). Therefore, Hypothesis 1 "The experimental group that received hope intervention will have a higher level of hope than the control group" was supported. Hypothesis 2 "The experimental group that received hope intervention will have a higher level of quality of life than the control group", was not supported (t=-1.726, p=.092). CONCLUSION: Hope intervention is an effective nursing intervention to enhance hope for patients with cancer staying at home.

The author studied the functional derangement of blood-retinal barrier induced by destruction of the pigment epithelial cells of the retina. Sodium iodate, which was well known to exert a selectively destructive action to the retinal pigment epithelial cells, was injected to the rabbits intravenously(60mg/kg of body weight). Eyes were enucleated 2 days and 4 days after sodium iodate injection and examined by electron microscope. Some of the tissue were fixed in colloid lanthanum, to investigate the changes of the permeability of plasma membrane in accordance with cellular damages induced by sodium iodate. The permeability of the blood-retinal barrier was also studied after intravenous(200mg/kg) or intraocular(4 microgram/20ml of saline) injection of horseradish peroxidase(HRP). The results obtained were summarized as the following: Sodium iodate induced patchy areas of loss of pigment epithelial cells after 2 days, which were more widespread and severe after 4 days with regenerative activities. Loss of outer segment and mitochondrial swelling of the inner segment of visual cells were also noted after 4 days. Colloidal lanthanum penetrated into the mitochondria of pigment epithelial cells at 2 days after sodium iodate injection, which was extended to the mitochondria of inner segment of visual cells after 4 days. Intraocularly injected HRP appeared from the internal limiting membrane to Bruch's membrane after 2 days. Intravenously injected HRP appeared from the Bruch's membrane to ganglion cell layer after 2 days, which were extended to the vitreal cavity. The results suggested that the damage of the pigment epithelial cells induced by sodium iodate destroy blood-retinal barrier. HRP exudation is more extensive in direction of retina to choroid than choroid to retina.

Adenoid cystic carcinoma of the lung is histologically and ultrastructurally identical to the salivary gland tumor of the same name and is characterized by infiltrative growth, local recurrence, and usually a prolonged clinical course. We have recently experienced two cases of adenoid cystic carcinoma arising in the lung. Case 1 was a 59 year-old male who presented with cough, fever, and chill of 1.5 months' duration, and case 2 was a 61 year-old male who was incidentally found to have a 3 to 4 cm sized lobulated mass in the right upper lobe. After being worked up, both patients underwent right pneumonectomy. In case 1, a 3x2 cm sized tumor was located in the lower bronchus, partly elevating toward the lumen and partly infiltrating into regional lymph nodes and lung parenchyma showing grayish-white and solid cut surface. Case 2 was a 3.5x3.5 cm sized upper bronchial tumor resembling the former in appearance. Histologically, the tumors were composed of small round hyperchromatic cells, forming solid, cribriform, acinar, or tubular structures. Luminal spaces in tumor cell nests contained PAS-positive mucinous or hyaline material. Among the tumor cells, scattered islands of normal submucosal gland were noticed.

The term "entropion" is defined as a turning inward of the eyelid. Depending on the mechanism of its causation, it may be classified into four types; mechanical, spastic, senile, and cicatricial. Cicatricial entropion follows scarring of the palpebral conjunctiva, which may be caused by trauma, chemical injuries, infections such as trachoma, benign ocular pemphigus, Stevens-Johnson syndrome, and eyelid surgery. Distichiasis is a rare congenital anomaly in which aberrant separate row of lashes usually composed of hairs smaller than normal, appears along the posterior lid margin. Numerous surgical procedures have been described for surgical correction of cicatricial entropion and distichiasis in accordance with the severity of the condition. We have treated cicatricial entropion in 6 eyes(8 lids) and distichiasis in 3 eyes (3 lids) with sliding tarsoconjunctival grafting, and the results were satisfactory.

PURPOSE: We report a case of acute visual loss with ophthalmoplegia after prone position spinal surgery who had blood supply dependence on collateral circulation due to occlusion of the Internal carotid artery. CASE SUMMARY: A 74-year-old man was referred to the department of ophthalmology for acute visual loss and ophthalmoplegia after lumbar spine surgery performed in prone position. On the initial visit, his right visual acuity was 0.8 and the left visual acuity was negative light perception. Intraocular pressure was normal. There was a relative afferent pupillary defect and ophthalmoplegia of all directions in the left eye. Because of the ptosis of the upper eyelid in the left eye, it was impossible to tune the eye voluntarily. The cherry red spot and pale retina were observed on the fundus examination. On brain magnetic resonance imaging angiography, we found complete obstruction of the left internal carotid artery. He had intravenous injection of 1 g methylprednisolone for 3 days, and discharged with per oral medicine. After 1 month of treatment, the ophthalmoplegia was slightly improved, but visual acuity was not recovered. CONCLUSIONS: In this case, unlike previous reports, acute visual loss and ophthalmoplegia occurred after spinal surgery the patient who had collateral circulation for ocular blood supply because of complete obstruction of the left internal carotid artery. This report highlights the importance of being aware of the anatomical variant in possible complications of external ocular compression after non-ocular surgery.

BACKGROUND: Histological analysis of tuberculosis shows a spectrum of findings, from well formed granulmatous inflammation with few bacilli in patient with normal immune response to M. tuberculosis to poorly formed granulomatous inflammation with many bacilli in patient with defective immune response. To evaluate the degree of immune response to M. tuberculosis, we studied the histologic features, including the presence of acid fast bacilli(AFB) in lymph node of patients with cervical tuberculous lymphadenitis, and compared them with clinical characteristics. METHODS: We reviewed the histologic features of 33 cases of cervical tuberculous lymphadenitis and processed the excised nodes for auramine-rhodamine staining to detect AFB. The AFB positivity in tissue was compared with the histologic features(degree of granuloma formation, presence of caseation necrosis, presence of neutrophilic infiltration) and clinical characteristics (lymph node size, duration of symptom, presence of local symptom or radiologic evidence of pulmonary tuberculosis). RESULTS: 1) The mean age at diagnosis was 42.4 years, and male to female ratio was 1 : 45. 2) Histologically, all cases showed well formed granuloma and variable degrees of caseation necrosis, and 39% of the cases showed neutrophilic infiltration in the granulomatous inflammation. 3) AFB were confirmed in 52% of the cases, and they were found extracellularly and at the periphery of caseation necrosis. 4) There was no association between AFB Positivity and histological features or clinical characteristics. CONCLUSION: Cervical tuberculous lymphadenitis showed well formed granulomatous inflammation with caseation necrosis, and there was no association between AFB positivity in the tissue and histological or clinical characteristics.
