Incontinentia pigmenti is an uncommon neurocutaneous genodermatosis characterized by three stages; vesicular lesions, verrucous lesions and hyperpigmentation. A two-week-old female infant showed grouped erythema-based vesiculopustules on the whole body since birth. One month later, vesiculopustular lesions began to disappear gradually. At this time, she developed linear verrucous plaques on the dorsum of the feet and hands and reticulated hyperpigmented patches on the lower extremities. At 2 months of age, vesicular lesions completely disappeared and the pigmented patches spread to the abdomen which became darker with time. The verrucous lesions diminished at 3 months of age. There were no neurological or ocular defects. We describe a case of incontinentia pigmenti with typical clinical and pathological features at each stage.

BACKGROUND: There is a long-standing controversy whether melanocytes in vitiligo of more than 1 year duration are actually lost or still present. Resolving this matter is essential in understanding the underlying pathology and for the development of the treatment. On previous immunohistochemical and ultrastructural studies of vitiligo lesions, damage of melanocyte and keratinocyte in early lesions were reported and complete absence of melanocyte in long standing lesions were known. OBJECTIVE: This study aimed to determine the existence of the differences in pathologic changes in melanocytes according to the duration of the lesion. METHODS: We investigated the vitiliginous skin samples from 31 patients with early(less than 1 year duration) vitiligo and 30 patients with long standing(l to 5 years duration) vitiligo under the electron microscopy. RESULTS: Multiple degenerative changes in melanocytes were observed in the early and long standing lesions. In long standing lesions, degeneration of melanocytes including pyknotic, in-dented nuclei, vacuolated cytoplasms and blunted dendrites were more pronounced than early lesions. Even in long standing lesions, definite or presumptive melanocytes were observed in 16(53.3%) of 30 cases. CONCLUSION: Our results suggest that the melanocytes of vitiligo lesions were damaged and that the percentage of degenerative changes increase in accordance with the duration of the lesion. However, in long standing lesions as well as in early lesions, some residual melanocytes can be observed ultrastructurally.

Nonconvulsive status epilepticus (NCSE) is defined as continuous or nearly continous electrographic seizure activity lasting at least 30 minutes without clinical signs of convulsive activity. The presence of NCSE after the control of clinical status epilepticus (SE) is a significant prognostic indicator of outcome for SE. We report a case of a 25 year-old male patient that had viral encephalitis and showed electrographic seizure on electroencephalography (EEG) that persisted after the control of convulsive status epilepticus. The patient was treated with isoflurane under general anesthesia for 5 days after the standard antiepileptic drugs failed. We discontinued the use of isoflurane after NCSE reached optimal burst suppression, as seen on EEG, and it was controlled well with antiepileptic drugs.

BACKGROUND: The safety and efficacy of trabeculectomy with Mitomycin C (MMC) for surgical treatment in aphakic and pseudophaic eyes were retrospectively evaluated. MATERIALS AND METHODS: The authors reviewed 51 eyes of 45 patients who had been followed up for at least 6 months after trabeculectomy using MMC for aphakic and pseudophakic eyes. The success rate and complications were analyzed. The success criteria included intraocular pressures of 21 mmHg or less with or without glaucoma medications and no loss of light perception. Surgical failure was defined as a postoperative loss of light perception in patients with preoperative vision better than light perception, additional glaucoma surgery, or phthisis bulbi in patients with preoperative vision of no light perception. RESULTS: The average follow up period was 27.7 months and the intraocular pressure was controlled under 21 mmHg in 36 eyes of 51 (70.6%) after the procedure with or without medication for glaucoma. Using the Kaplan-Meier survival analysis, the cumulative success rate at the 3-, 6-, 12-, 24- and 36-month intervals were 98.0%, 94.1%, 91.9%, 83.4% and 75.5%, respectively. The complications observed were hyphema (4 eyes), serous choroidal detachment (4 eyes), hypotony (3 eyes), and endophthalmitis (1 eye). CONCLUSION: Trabeculectomy using Mitomycin C for the treatment of aphakic and pseudophaic eyes was safe and effective.

One hundred seven isolates of Staphylococcus aureus from bovine mastitis were investigated for colony morphology in serum-soft agar (SSA), autoagglutination in salt, and capsular serotype. Capsular polysaccharide (CP) was purified and quantified from the extracts of clinical isolates. Overall, 89 isolates (83.2%) were diffuse in the SSA, without any difference in the proportion of diffuse colony between type 5 and type 8 strains. Some strains exhibited compact colonies in the SSA and expressed CP as determined by an enzyme-linked immunosorbent assay, indicating that compact morphology does not exclude encapsulation. The majority of the strains (11/12) showed autoagglutination in the salt aggregation test. The serotype 336 accounted for 46.7% of the isolates followed by serotype 5 (12.1%) and serotype 8 (12.1%). Particularly, twenty-six (24.3%) isolates reacted with two serotypes; 7 for type 8/336 and 19 for type 5/336. Five isolates (4.7%) were nontypeable with monoclonal antibodies specific for CP serotype 5, 8, or 336. The CP concentration in culture supernatants varied with the serotypes, and the total amount of CP produced by cells grown in a liquid medium was much less than that produced by cells grown on a solid medium. The Western blotting indicated that the CP bands of S. aureus serotype 5 and 8 were ranged in the molecular mass of 58-84 kilodalton (kDa), with additional bands in the region of approximately >or= 48 or Agglutination Tests ; Animals ; Bacterial Vaccines/administration & dosage ; Cattle ; Cattle Diseases/immunology/microbiology ; Female ; Mastitis, Bovine/*microbiology ; Polysaccharides, Bacterial/*classification/isolation & purification ; Serotyping/methods/veterinary ; Staphylococcal Infections/immunology/*veterinary ; Staphylococcus aureus/*classification/*immunology/isolation & purification

The bonded orthodontic retainer constructed from composite and multistrand orthodontic wire provides an esthetic and efficient system for maintained retention. This study was designed to measure shear bond strength of bonded retainers and to suggest a optimal combination of a multistrand wire and bonding method used when bonded retainer was fabricated. 160 sound maxillary and mandibular premolars were used for 80 test samples. After Uniformizing bonding area, length of wire, and thickness of composite, multistrand wire was bonded to fabricated a bonded retainer by direct or indirect bonding method. Shear bond strength and extension length of each sample were measured by a universal testing machine. The results of this study were as follows: 1. In vitro shear bond testing found 6-stranded, 0.0155 inch wires to have the largest shear bond strength and 3-stranded, 0.0195 inch wires to have the least shear bond strength. But, These difference was not statistically significant(p<0.05). 2. In vitro extension testing found 3-stranded, 0.0155 inch wires to have the largest extension length and 3-stranded, 0.0195 inch wires to have the least extension length(p<0.05). The larger diameter wire was used, the larger extension length was shown. But, the strand of wire is not related to the extension length of wire. 3. In comparison with direct bonding method, larger shear bond strength and extension length was shown in indirect bonding method(p<0.05).

OBJECTIVE: The goal of this study was to determine the efficacy of caudal epidural injection in relieving pseudoclaudication of patients with lumbar spinal stenosis. METHOD: Fifteen patients with a spinal stenosis which was confirmed by the magnetic resonance imaging(MRI) studies, received a caudal epidural steroid injection of triamcinolone acetate 120 mg, in a solution mixed with 2 ml of 1% lidocaine, and 15 ml of normal saline. RESULTS: The visual analogue scales checked at 1 hour prior to injection, 1 hour postinjection, and 1 month postinjection were 8.1+/-0.8, 3.7+/-1.7, and 6.4+/-1.9, respectively. The exercise tolerance on the treadmill with 0o ramp inclination and 1.8 km/h speed was measured at 1 hour prior to injection, 1 hour postinjection, and 1 month postinjection. The time intervals to the first symptom of the pseudoclaudication were 2.3+/-0.8 minutes, 6.5+/-0.7 minutes, and 4.6+/-1.9 minutes, respectively. CONCLUSION: In our study, the caudal epidural injection offered a significant short-term relief for the pseudoclaudication. Also it appeared to be a reasonable therapeutic option among patients with lumbar spinal stenosis after 1 month postinjection.
