Cyclic Neutropenia is a benign, unusual hematologic disorder characterized by regularly recurring episodes of severe neutropenia occurring approximately every 21 days. Beside neutrophils, monocytes, lymphocytes, platelets and reticulocytes all cycle with strict periodicity suggest that this disease should be viewed as cyclic hematopoiesis, not merely as cyclic neutropenia. During neutropenic periods, patients regularly experience aphthous stomatitis, fever, malaise, cervical lymphadenitis, cutaneous infections and occasional pneumonia and otitis media. The exact cause of cyclic neutropenia is unknown. But it is strongly suggested that cyclic neurtopenia is due to an abnormality in the regulation of early hematopoietic precursor cells. We have documented a case of cyclic neutropenia for a period of 2.5 years in a 11 year-old boy who had suffered from recurrent fever, stomatitis, gingival swelling, cervical lymphadenitis and skin infections at 3 weeks intervals since 5 years of age. A brief review of the related literatures is presented.

The purpose of this phenomenological study was to explore and describe the experience of people with HIV/AIDS. Three men and three women with HIV/AIDS participated in the study. They were asked open-ended and descriptive questions in order for them to talk about their experience in their own terms. Interviews were audiotaped and transcribed to maintain data integrity and to reduce perceptual bias. The transcripts were analyzed by the Colaizzi method. Member checks from the participants were used to validate the emergent themes. Seven themes emerged from the analysis. 1. People with HIV/AIDS have a strong impact and emotional reaction when receiving positive HIV test results. 2. All people with HIV/AIDS attempt to conceal HIV infection because of fear of stigma or rejection. 3. After the initial brief traumatic reaction to HIV/AIDS diagnosis, all participants feel lonely because they had no one to express or share their own experiences. 4. People with HIV/AIDS reflect on their life, think about the death and dying process and they become depressed. 5. Most participants feel that the family members who know his/her diagnosis are a big source of support. 6. According to the normativeness of infection route of HIV, the degree of guilty feeling differs among participants. 7. Although all participants think medication is a lifeline, the adherence to medication is not maintained because of side effects, denial and concealment of HIV/AIDS. The results of this study may help nurses and other health care workers to implement more efficient nursing strategies for people with HIV/AIDS by more deeply understanding their experience.

Korean National Health Insurance (NHI) was established during only 12 yr from its inception (1977-1989), providing universal medical coverage to the entire nation and making a huge contribution to medical security. However, the program now faces many challenges in terms of sustainability. The low birth rates, aging population, low economic growth, and escalating demands for welfare, as well as unification issues, all add pressure to the sustainability of NHI. The old paradigm of low contribution - low benefits coverage - low NHI's fee schedule needs to be replaced by a new paradigm of proper contribution - adequate benefit coverage - fair NHI's fee schedule. This new paradigm will require reform of NHI's operating system, funding, and spending.

Infection involving the spinal cord and cauda equina are much less common than intracranial infection. Among the above, bacterial infection in spinal epidural space are relatively uncommon but well recognized entity in adult and children. More than 300 cases with spinal epidural abscess are described in the literatures. Because of its rarity, there is delay in diagnosis and irreversible neurological sequelae in high percentage of cases. Infection of the spinal epidural space are accompanied by fever, tachycardia, headache, pain and tenderness in the back, weakness of the lower extremities and finally a complete paraplegia. The modes of infection are 1) direct extension from inflammatory process in adjacent tissues 2) perforating wounds or lumbar puncture 3) hematogenous route from the remote origin. The most frequent causative organism is staphylococcus aureus always, but pneumococcus, streptococcus, pseudomonas, typhoid bacillus, pyocyanus, oidium coccidioides and fungus are causative organisms occasionally. In spinal epidural abscess with complete paraplegia, the neurologic sequelae are permanent and unhappy. So the spinal epidural abscess is neurosurgical emergency in which early diagnosis and prompt surgery are necessary to avert permanent cord damage. Recently, the spinal epidural abscess has increasing tendency. We have treated 5 cases with spinal epidural abscesses from Nov. 1974 to Apr. 1976. The followings are results ; 1) Sex incidence showed male 2, female 3 and age incidence ranged from 21 years to 38 years, but 4th decade was most common. 2) Most common mode of infection was unknown though all cases have been applied the acupunture for the back pain several times. 3) Most avaliable procedures of diagnosis were the usual infectious symptoms, leukocytosis, increased erythrocyte sedimentation rate, obstructive responce by Queckenstedt test and findings of myelography, including increased protein and pleocytosis in cerebrospinal fluid. 4) All 5 cases had been performed total laminectomy from T3-L3, according to the lesions commonly in thoracic spine with spinal epidural abscess and had been treated with penicillin G, Methicillin and Geopen. 5) The prognosis was poor in 4 cases with complete paraplegia but 1 case with incomplete paralysis recovered completely.

BACKGROUND AND OBJECTIVES: Even short-term treatment with angiotensin converting enzyme inhibitor in essential hypertension has been known to improve left ventricular (LV) diastolic function, LV hypertrophy (LVH), and aortic stiffness. The purpose of this study was to examine the effects of angiotensin II receptor antagonist (Losartan) on LV diastolic function, LVH, and aortic stiffness in essential hypertension. MATERIALS AND METHODS: Twenty-three hypertensive patients who were aged over 50 years, previously untreated, and without cardiac, renal, neurologic disease, or diabetes, were studied. Before and 12 weeks after monotherapy with Losartan 50 mg q.d., (1) supine arterial blood pressure by sphygmomanometry, (2) interventricular septum and LV posterior wall thickness, and LV end-diastolic dimension by M-mode echocardiography, (3) mitral peak E and A wave velocity by doppler echocardiography, (4) pulse wave velocity (PWV) in the descending aorta from aortic arch to the bifurcation by doppler echocardiography, were done. RESULTS: Twelve weeks after treatment, systolic blood pressure was lowered from 168.2+/-3.5 mmHg to 142.9+/-2.9 mmHg (p<0.05), diastolic blood pressure from 98.52.4 mmHg to 87.51.3 mmHg (p<0.05). Peak E/A ratio was increased from 0.75+/-0.04 to 0.82+/-0.04 (p<0.05). LV mass was decreased from 267.5+/-15.8 g to 235.6+/-12.6 g (p<0.05), and LV mass index from 166.8+/-8.0 g/m2 to 146.9+/-6.0 g/m2 (p<0.05). However, there were no significant change in PWV (from 7.18+/-0.10 m/sec to 7.23+/-0.30 m/sec, p>0.05), compliance (from 1.31+/-0.04 to 1.34+/-0.12, p>0.05), and compliance index (from 0.16+/-0.01 to 0.15+/-0.01, p>0.05). CONCLUSION: Short-term treatment with Losartan decreases blood pressure, improves LV diastolic function and LVH, but not aortic stiffness.

The syndrome of postural headache associated with low CSF pressure usually occurs after a dural puncture, myelography, or spinal anesthesia. However, it can also develop spontaneously or after minor trauma. Although the clinical and MRI findings of this syndrome are well described, radionuclide cisterno-graphic findings have not yet been clearly characterized. We report four patients presenting with postural headache associated with very low or unmeasurable CSF pressure. Three patients developed after minor trauma, while one developed spontaneously. Brain MRI revealed symmetric pachymeningeal enhancement in all four patients. Radionuclide cisternography demonstrated delayed migration of tracer to the cerebral convexity at 6 and 24 hours in three patients, and early soft tissue uptake suggestive of CSF leakage in one. We suggest that these radionuclide cisternographic findings are supportive evidences for the presence of intracranial hypotension and may provide useful information for appropriate treatment.
