Developmental venous anomalies are congenital anomalies of the intracranial venous drainage and clinically asymptomatic. Cavernous hemangiomas are vascular malformations composed of dilated vascular channels lined with a single layer of endothelial cells without any intervening normal neural tissue. Although, cavernous hemangioma may be clinically silent, but frequently cause variable neurologic manifestations; intracranial hemorrhage, seizures, and focal neurologic deficits. Frequent association of these two diseases has already been reported and it has been suggested that cavernous hemangiomas not the developmental venous anomalies that cause the acute clinical symptoms. A 4 year old girl with sudden onset of headache, vomiting, gait disturbance and signs of unilateral cerebellar dysfunction 2 days before admission showed a 2.5x2.5cm sized hematoma with heterogenous signal intensity both in CT and MRI in the left cerebellar hemisphere. Four-vessel cerebral angiography revealed characteristic findings of developmental venous anomalies. Pathologic findings of the surgically removed hematoma disclosed typical feature of cavernous hemangioma. Based on the findings in this case and review of the literatures, we concluded that the possibility of other diseases such as cavernous hemangiomas must be considered in patients who has intracranial hemorrhage due to the developmental venous anomalies.

BACKGROUND: Respiratory atopy (RA) is frequently associated with atopic dermatitis (AD) and the age of onset is usually later than that of the dermatitis. OBJECTIVE: The aim of this study was to investigate the prevalence, the onset, and the duration of RA associated with AD in Korea. We also tried to correlate the existence of RA with the severity and prognosis of AD. METHODS: One hundred and eighty one patients with AD were studied. Information about the age at onset and the duration of RA were obtained from the medical history of patients or from the medical records. The severity of AD was graded. RESULTS: RA was found in 66 cases of AD (36.5%). The average age at onset of asthma was 6 years and the average duration of asthma was 6 years. The average age at onset of allergic rhinitis (AR) was 12.4 years and the average duration of AR was 6.8 years. The prevalence of asthma with AD was the most common in the age group between 8 and 11 years while the prevalence of AR was the most common in the age group between 20 and 23 years. The higher occurrence of RA in the older age group was considered to represent persistence of AD in-to adult life. We could not find any difference in the severity of AD between pure AD patients and AD patients with RA. CONCLUSION: The prevalence of RA in AD in Korea was considered to be similar to that of other reports. The average onset of asthma in Korea was a little later, whereas the average on-set of AR was a little earlier than that in the other reports. The duration of RA, which has hardly been mentioned in the literature, was considered to be about 6 years in Korea. It is likely that RA is a poor prognostic factor for AD, but does not affect severity of dermatitis.

BACKGROUND: Oculocutaneous albinism (OCA) is a genetic disorder of the melanin pigment system in which melanin synthesis is reduced or absent in the skin, hair, and eyes. OCA is classified into two major types, and tyrosinase-related OCA can be produced by mutations of the structural gene for tyrosinase enzyme (TYR gene). OBJECTIVE: The purpose of this study was to analyze the segregation of mutant alleles of the TYR gene in tyrosinase-negative and tyrosinase-positive Korean OCA patients and families. METHODS: We amplified exon I, II, and III of the TYR gene of Korean OCA patients and their families by polymerase chain reactions (PCR), and analyzed the mutations by restriction fragment length polymorphism (RFLP) analysis in exon I and single-strand conformation polymorphism (SSCP) analyses in exon II and exon III. RESULTS: Two tyrosinase-negative cases showed mutations in exon I. Four tyrosinase-nega-tive cases and one tyrosinase-positive case showed mutations in exon II, and one tyrosinase-neg- ative case showed mutations in exon III. In summary, we found three kinds of mutation in four tyrosinase-negative OCA patients and one tyrsinase-positive OCA patient. CONCLUSIONS: RFLP and SSCP analysis can provide a basis for a rapid and sensitive screening system to detect TYR gene mutations of Korean OCA patients and their families.

In 2007, the Public Sanitation Administration Law in Korea was partially amended to subdivide cosmetology into general and skin cosmetology. Thus starting from 2008, a skin cosmetology qualification requirement license was newly created in Korea. Instead of improving the health standards concerning public health, the amendments have exaggerated the monopolistic right of trade of the Korean Central Esthetician's Association with the assistance of the Division of Sanitary Policy in the Korean Ministry for Health. In addition, the amended ordinances stipulate that cosmetologists can analyze skin conditions, hence allowing medical diagnostic procedures by non-medical personnel which has serious health problems causing serious conflict with Korean Medical Law. Legislation precedents from around the world demonstrate that medical supervision by physicians is absolutely necessary with fastidious requisitions in order to safeguard public health. However, in Korea there is a subversive attempt by some esthetician groups to limit the employment of estheticians by medical institutions in order to safeguard their private privileges. The newly amended Public Sanitation Administration Law should be revised in order to preserve the fundamental rights of the people, to enhance public health, and to uphold the well being of the people instead of catering to special interest groups.

Autogenous costal cartilage graft has been commonly used for reconstruction of auricular deformity. However, the risk of complication and discomfort at the donor site, as well as distortion of the graft due to morphological change in the cartilage have been serious drawbacks to this procedure. Previous studies examining the chondrogenic potential of perichondrium have suggested that perichondrium may be used as graft for cartilage reconstruction. When a perichondrial flap or a free perichondrium was used as graft, new cartilage formed appositional to the grafted perichondrium. However, the neocartilage was often irregular in shape and varied considerably in quantity. In this study, the feasibility of controlling the shape and the mass of neocartilage was investigated using coral, a porous biomaterial, as a template. A coral a template was wrapped with perichondrial flap from the ears of New Zealand white rabbits and placed into a subcutaneous pocket in the rabbits and placed into a subcutaneous pocket in the rabbit's back by incision. A total of 12 animals were used. Formation of new cartilage was later evaluated by gross and histological examination of the perichondrial flap and the coral template. New cartilage was formed in 11 animals. Immature chondrocytes were visible by 3 weeks after the surgery, and by 8 weeks the immature chondrocytes had formed a cartilage. New cartilage was formed only on the surface of the coral template. These results indicated that the shape and the mass of new cartilage may be controlled by using coral template. Therefore, the desired shape of cartilage may be achieved using a coral template of corresponding shape, and this may help in correcting subtle auricular contour defect and in correcting other structural defects that also require new cartilage formation.

BACKGROUND: One of the main disadvantages of caudal block is the long latent period before a satisfactory blockade is obtained. Many investigators have used various preparations of local anesthetic solutions to improve the speed of onset. This study was performed to evaluate the effectiveness of prewarming of lidocaine HCl for caudal block. METHODS: Fifty healthy young patients (ASA I) were allocated into two groups, A and B. In group A, the local anesthetic solution were injected at room temperature (25 degrees C), while in group B, they were injected at 37oC. All the caudal block were performed using 2% lidocaine HCl 20 ml with fentanyl 100ug and epinephrine 1:200,000. The onset time was defined as the period from completion of injection until the patient first noticed loss of sensation to pin-prick on perianal region. Assessment of sensory loss was made at 15 seconds interval. We have compared the onset of sensory blockade between groups. The duration of analgesia and any significant side effects were also recorded. RESULTS: The onset of sensory blockade was significantly faster in group B (3.5 +/- 0.5 minutes) than group A (6.2 +/- 0.9 minutes). The duration of analgesia were not significantly changed between groups. Side effects of urinary retention, pruritus and nausea were noted between both groups but the difference was not significant. CONCLUSIONS: We have found that the onset time was 44% faster with warm lidocaine-fentanyl mixture (37 degrees C) than with the room temperature (25 degrees C). The improved clinical usefulness was achieved with no increase in side effects. The technique is a safe and effective method to reduce the latency of onset.

We report a case of malignant histiocytosis which began with intermittent fever and scaly skin lesions. A 3-year-old girl presented with erythematous scaly papules on the face and the trunk, and high fever for 3 months. The cutaneous lesions consisted of widespread coin-sized erythematous scaly papules with marginal brownish pigmentation. She was anemic and thrombocytopenic and had impairment of the liver function. Histopathologic study of the skin lesions showed non-specfic findings except for hyperkeratosis. However, bone marrow examination revealed an increased number of histiocytes, mostly immature with active phagocytosis of erythroid cells, myeloid cells, and platelets. She was diagnosed as having malignant histiocytosis and treated with cyclophosphamide and vincristine. She died the next day after the treatment had begun.

Silicone gel breast implants may induce local(fibrous capsular contracture) or systemic(rheumatoid arthritis, systemic sclerosis, etc) complications. The exact mechanism of fibrous capsular contracture has not been fully understood. In the present study, we tried to find out the effect of silicone gel on the fibroblast proliferation which has been known as a major contributing factor in fibrous capsular contracture formation. In vitro, activated macrophages are known to secrete monokines which affect fibroblast proliferation and collagen synthesis. And tumour necrosis factor-alpha(TNF-alpha) and interleukin-6(IL-6), which were released by macrophages, were reported as potent stimulator of fibroblast proliferation. The goal of this study is to investigate the role of macrophages and tumour necrosis factor-alphaor interleukin-6 in the interaction of fibroblasts and silicone gel. We designed four groups, two experimental and two control, using Institute for Cancer Research(ICR) mouse peritioneal macrophage and silicone gel. For the preparation of the conditioned medium of macrophages, peritoneal macrophages were prepared and cultured for 24 hours on the silicone gel-coated and naked (not coated) surface [silicone gel-macrophage conditioned medium(SCM; experimental group) and normal polystyrene-macrophage conditioned medium(NCM; control group) respectively]. To correct the effect of 10% fetal bovine serum which was included in Rapid Prototyping and Manufacturing Institute (RPMI) 1640 medium and draw the effect only by macrophages, the RPMI 1640 medium with 10% fetal bovine serum was cultured by the same method on the silicone gel-coated and naked surface (silicone gel-macrophage free conditioned medium; SFM and normal polystyrene-macrophage free conditioned medium; NFM respectively). Each conditioned medium was added onto NIH 3T3 fibroblasts culture at a final 25% concentration of total culture medium and followed by the cultivation for 24 hours. For antibody neutralizing experiments, each conditioned medium was preincubated with polyclonal rabbit anti-mouse TNF-alpha antibody or polyclonal rat anti-mouse IL-6 antibody for 1 hour and then, conditioned medium with antibody was added to the culture medium of NIH 3T3 fibroblasts by the same method. After 24 hours cultivation, total number of viable fibroblast(cell growth), DNA synthesis and collagen synthesis of fibroblasts with each medium were measured by sulforhodamine B(SRB) assay, 3H-thymidine and 3H-proline incorporation respectively. The results were as follows: 1. In the experiment about the effect of the conditioned medium on the fibroblast activity, the experimental group(SCM), compared with the control group(NCM), showed a significant increase of the cell growth (p<0.01), a significant decrease of DNA synthesis(p<0.001), but no significant difference in the collagen synthesis. 2. In the experiment about the effect of polyclonal rabbit anti-mouse TNF-alpha antibody on the fibroblast activity, after the addition of antibody the experimental group, compared with the control group, showed a significant decrease of the cell growth(p<0.001), a significant increase of DNA synthesis(p<0.01), but no significant difference in the collagen syn thesis. 3. In the experiment about the effect of polyclonal rat anti-mouse IL-6 antibody on the fibroblast activity, after the addition of antibody the experimental group, compared with the control group, showed a significant decrease of the cell growth(p<0.001), a significant increase of DNA synthesis(p<0.0001), but no significant difference in the collagen synthesis. In conclusion, culture supernatants (conditioned medium) of peritoneal macrophages, activated by silicone gel, stimulate the NIH 3T3 fibroblast proliferation. TNF-alpha and IL-6, products of macrophage, are involved in the stimulation of NIH 3T3 fibroblast proliferation in an in vitro condition.

To assess the change of nitric oxide(NO) concentration according to photorefractive keratectomy(PRK) depth and the role of NO in cataractohenesis after excimer laser PRK. The treated 36 rabbits were divided into 12 groups according to PRK depth(-3.0, -7.0, -11.0 diopter [0]), the dates of sampling(the 1st day and the 7th day after PRK), and reatment of NOS inhibitor (NG-nitro-L-arginine methylester, L-NAME). NO concentration and superoxide dismutase(SOD) activity in the aqueous humor and malondialdehyde(MDA) concentration in the lens were measured. Changes of lens epithelium were examined by eletron microscopy on the 3rd day and the 6th day after -11.0D of PRK. The NO and MDA concentration in the group without L-NAME treatment on the 1st day after -11.0D of PRK were significantly higher than those in the L-NAME treated group and control group. The activity of SOD increased in all of the PRK treated group on the 1st day and was even higher on the 7th day. The histopathological changes of lens epithelium on the 3rd day after PRK were compatible with cellular necrosis and those of the 6th day after PRK were compatible with cellular reparing. The results suggested that the toxicity of NO after PRK correcting over -11.0D may a role in cataractogenesis, but the progress could be suppressed by treatment of NOS inhibitor.
