Creutzfeldt-Jakob disease(CJD) is characterized clinically by rapidly progressive dementia with pyramidal, extrapyramidal, and cerebellar symptoms and signs, and histologically by spongiform change, neuronal loss and reactive gliosis. We have experienced 2 cases of CJD. Case 1 was a 36-year-old male who had suffered from myoclonus and cerebellar symptoms including sluggish speech, gait and balance disturbance. Case 2 was a 70-year-old female who had showed cognitive dysfunction, ataxic gait and disturbance of extraocular movement. Both patients, underwent brain biopsy. Case 1 revealed marked cortical atrophy, 2mm in thickness, with neuronal loss and astrocytic proliferation extending into white matter. The spongiform change, made up of many small, usually rounded or oval, vacuoles was noted mainly in the neuropil. Case 2 revealed remarkable spongiform change throughout the cortex and cytoplasmic vacuoles compressing the nuclei of neuronal cells were numerous. Neuronal loss and gliosis were also found without considerable change in the white matter. On double immunostaining against GFAP and PrP(Prion Protein), there was a weak positive reaction for PrP in the perinuclear cytoplasm in case 1, and a strongly positive reaction in case 2. The electron microscopic examination showed numerous membrane-bound vacuoles in neuropil and perikarya of neurons. The majority of the vacuoles were multiseptated by thin membranous structures. They demonstrated curled, or disrupted membrane, that had foldings and protrusions into the vacuolar clear spaces. There were neither identifiable virus-like particles nor amyloid deposition.

2.A Fatal Case of Severe Hemolytic Disease of Newborn Associated with Anti-Jk(b).
Journal of Korean Medical Science 2006;21(1):151-154
The Kidd blood group is clinically significant since the Jk antibodies can cause acute and delayed transfusion reactions as well as hemolytic disease of newborn (HDN). In general, HDN due to anti-Jk(b) incompatibility is rare and it usually displays mild clinical symptoms with a favorable prognosis. Yet, we apparently experienced the second case of HDN due to anti-Jk(b) with severe clinical symptoms and a fatal outcome. A female patient having the AB, Rh(D)-positive boodtype was admitted for jaundice on the fourth day after birth. At the time of admission, the patient was lethargic and exhibited high pitched crying. The laboratory data indicated a hemoglobin value of 11.4 mg/dL, a reticulocyte count of 14.9% and a total bilirubin of 46.1 mg/dL, a direct bilirubin of 1.1 mg/dL and a strong positive result (+++) on the direct Coomb's test. As a result of the identification of irregular antibody from the maternal serum, anti-Jk(b) was detected, which was also found in the eluate made from infant's blood. Despite the aggressive treatment with exchange transfusion and intensive phototherapy, the patient died of intractable seizure and acute renal failure on the fourth day of admission. Therefore, pediatricians should be aware of the clinical courses of hemolytic jaundice due to anti-Jk(b), and they should be ready to treat this disease with active therapeutic interventions.

The use of osseointegrated implants is an accepted procedure for the treatment of Total, or partial edentulism and offers good predictability of long-term success. Osseointegration implies a firm and direct interlocking between vital bone and screw-shaped titanium implants. There should be not to interposed tissue between fixture and bone. This study was undertaken to assess the clinical condition, complication, and prosthodontic aftercare of different implant systems. One hundred fifty-nine patients treated with a total of 503 endosseous implants (364 Steri-oss threaded type, 69 Integral cylinder with HA coated type, 35 Steri-oss threaded with HA coated type, 21 Steri-oss cylinder with HA coated type and 14 3i implant type), Most of the implant were placed in type B and C bone quantity and type 2 and 3 bone quality according to Lekhorm and Zarb. The success rate of Steri-oss threaded type during healing and function was 92%, Steri-oss threaded type with hydroxyapatite coated was 91%, Steri-oss cylinder type with hydroxyapatite coated was 90%, Integral cylinder type with hydroxyapatite coated was 90% and 3i implant type was 93%. One hundred twenty-nine patients had been treated with implant prosthesis. 79 of these patients had received a fixed type prosthesis and 50 patients had received a removable type prosthesis. There were no differences between the implant systems with regard to age, gender. Failures were associated with poor bone quality, smaller implant sizes, a surgical installation technique and stress distribution when in function. Visual analgoue scales recorded as satisfied results functionally and esthetically, but 15% dissatified with chewing ability.

Common peroneal neuropathy during normal delivery is associated with instrumentation and prolonged time spent in a certain position. We report a case of unilateral common peroneal neuropathy in a vaginal delivery patient under labor analgesia with the combined spinal-epidural technique. A 29-year-old woman complained of weakness and numbness of the left foot two days after vaginal delivery. Neurologic examination and electrodiagnostic testing confirmed left common peroneal neuropathy. The patient was referred for rehabilitation, which substantially improved her mobility and function, and prevented secondary damage. The patient had not fully recovered at three months after the delivery. The possible etiology of the postpartum common peroneal neuropathy was most likely prolonged and excessive pressure around the knee by assistants. Excessive compression during delivery should be minimized or avoided. Patient education and awareness among the labor and delivery team will prevent this complication. Neurologic complications related to epidural analgesia should also be ruled out in these patients.

BACKGROUND: Psoriasis is a chronic skin disease characterized histologically by prominent keratinocyte hyperplasia and an early inflammatory cell infiltrate. However, the pathogenesis is not fully understood yet. Recently, there has been growing interest in the probable role of a T cell mediated immune response in the pathogenesis. Especially, cytokine network involved in psoriasis has been studied. OBJECTIVE: This study was done to investigate the role of Interleukin-8(IL-8) and its inducer, Tumor necrosis factor-alpha(TNF-alpha) for pathogenesis of psoriasis. METHODS: We performed immunohistochemical staining using antibodies for IL-8 and TNF-alpha in frozen skin samples of 14 psoriatic patients who had not been treated for psoriatic lesion for 1 month and 3 normal skin samples as controls. RESULTS: There was no detectable discrete immunoreactivity for either TNF-alpha and IL-8 in epidermis and dermis of normal controls. In psoriatic lesions, the expression of TNF-alpha was found in dermal cells within the papillary dermis, particularly around blood vessels. The expression of IL-8 was presented on suprabasal keratinocytes above TNF-alpha-positive dermal tissue. CONCLUSION: Our results strongly suggest that histologic expression and functional interaction between IL-8 and its inducer, TNF-alpha have significant roles in the pathogenesis of psoriasis.

Segmental neurofibromatosis is a rare disorder characterized by cafe-au-lait spots and neurofibrobmas, or only neurofibroma, limited to one region of the body. Disease-associated systemic involvement is uncommon. Most patients with segmental neurofibromatosis do not have a family history of neurofibromatosis. In Korea, there have been 3 reported cases of segmental neurofibromatosis. None of them had caf6-au-fait spots, systemic involvement, or family history. This report describes a case of segmental neurofibromatosis in a 25-year-old woman who had Becker's nevus-like cafe-au-lait spots and this was linked to the presence of Fanconi's syndrome in a second degree relative of the patient.

Prurigo pigmentosa is a distinct type of inflammatory dermatosis characterized by recurrent pruritic erythematous papules that resolve, leaving a peculiar, reticulate hyperpigmentation. Although the cause of prurigo pigmentosa is unknown, exogenous factors, such as friction from clothing, have been suggested as possible triggers in some cases. In other cases, however, systemic conditions such as diabetes mellitus, pregnancy, fasting, and dieting were associated with prurigo pigmentosa, suggesting involvement of endogenous factors in the pathogenesis. There have been reported cases of prurigo pigmentosa associated with ketosis. Because ketosis is commonly observed in association with fasting, dieting, and insulin dependent diabetes melitus, it may be involved in the pathogenesis of prurigo pigmentosa. Here, we describe a patient with prurigo pigmentosa associated with diabetes mellitus and ketosis. In this case, the prurigo pigmentosa improved with the disappearance of the ketosis, but the blood sugar levels did not correlate with the improvement.

A 57-year old woman presented with a complaint of pain on the left chest wall, incision scar area, axillae, upper forearm and limitation of motions at left shoulder for 4 years. She was treated under the diagnosis of postmastectomy pain syndrome. Pain was constrictive, myalgia in characters and the visual analog scale was 4. She said that the pain was worse when tired and fatigued, but relieved when in the bath. Associated symptoms were not found. A cervical epidural puncture (C6/7) was performed and 1% lidocaine with triamcinolone was injected. Gabapentin 300 mg daily was also given. Tender points injection with 0.5% bupivacaine and dexamethasone was performed several times. Stellate ganglion block with 1% lidocaine was also included once in the treatment regimen. On the second visit at the outpatient clinic, she showed fairly good signs of relief of pain and limitation of motions, but still remained anxious and complained of feeling of anger, frustration, and a feeling of loss and suffering. Hypnotic analgesia was indicated. Two sessions (1 hour for one session) were scheduled in a quiet room. Feelings of magnetic power on both palms were used as an induction technique and imagination on escalator was adopted for the deepening hypnosis, arm levitation for dissociation, a warm feeling of body for changing sensation, progressive relaxation, symbolic imagery for posthypnotic suggestion (turning the radio button) and glove analgesia technique were tried. Self-hypnosis and ego-strengthening were instructed for further pain relief. After the treatment, she was quite satisfied due to reduction of pain and stabilization of mind.

An intravenous pyogenic granuloma is a rare, benign, intravascular tumor, which arises from the vein wall and protrudes into the lumen. This is characterized by a lobular proliferation of capillaries similar to the more common cutaneous pyogenic granulomas. We report a case of intravenous pyogenic granuloma which showed lobular capillary proliferation in the perivenous connective tissue.

BACKGROUND: Ephedrine has been recommended as the best vasopressor in obstetrics. But, recent clinical evidences show the possibility that phenylephrine has become more pertinent as a primary vasopressor. We think a phenylephrine infusion with colloid co-hydration will be more useful in maintaining baseline blood pressure in combined spinal-epidural anesthesia (CSEA) for cesarean section. METHODS: CSEA was performed using 6 mg bupivacaine and 20microgram fentanyl as a spinal and 10 ml of 0.25% levobupivacaine as an epidural in randomized, colloid co-hydration (hydroxyethl starch, HES 500 ml) (group C, n = 34) or no colloid co-hydration (group N, n=34) parturients scheduled to undergo cesarean delivery. After an infusion of 100microgram phenylephrine following the spinal injection, phenylephrine was intermittently infused using a PCA-pump to maintain the baseline blood pressure (BP). Systolic BP and heart rate (HR) were checked and total phenylephrine amount was measured. Nausea and vomiting and fetal umbilical pH/base excess (BE) were also investigated. RESULTS: There was a lower incidence of bradycardia in the C group compared with the N group (5.9% vs. 32.4%, p = 0.014), and total phenylephrine consumption was less in the C group (400microgram vs. 500microgram, p = 0.019). The incidence of reactive hypertension (11.8% vs. 55.9%, p < 0.001), and the hypotension (0% vs. 11.8%, p = 0.114) were lower in the C group, too. The others were comparable in both groups. CONCLUSIONS: Colloid co-hydration was effective in reducing the phenylephrine use and the incidences of abnormal hemodynamics such as hypotension, bradycardia and hypertension in low-dose CSEA for cesarean delivery.
