Sturge-Weber Syndrome*

The congenital diverticulum of ventricle is a rare cardiac malformation arising from the left or right ventricle, the former being more common. Ventricular diverticulum is usually associated with other anomalies including intracardiac, midline thoracic, diaphragmatic and abdominal wall defect. The authors experienced a case of congenital diverticulum of left ventricle in nine month-old female infant. Left Blolock-Taussig shunt operation was done and total correction will be done later. Thereafter we presented a case with brief review of the related literatures.

Reye Syndrome*

A 38-year-old woman was presented with a dark brown plaque on the abdomen. Clinically, the tumor was simulating the appearance of dysplastic nevus. Microscopically, the cells of the stratum malphighii lay in a disordered pattern. Many cells in the epidermis were atypical and melanin pigment was mainly in the basal layer of the epidermis and the upper dermis. Diagnosis of pigmented Bowen's disease was made. Pigmented Bowen's disease is rarely found at body sites other than the anogenital area.

STUDY DESIGN: We report two cases of symptomatic spinal epidural lipomatosis (SEL) associated with long-term use of steroid medication OBJECTIVES: The purpose of this study was to assess the clinical characteristics, diagnosis and treatment of symptomatic spinal epidural lipomatosis. SUMMARY OF LITERATURE REVIEW: Spinal epidural lipomatosis is a condition in which excess adipose tissue is deposited circumferentially about the spinal cord in the epidural space. It can present neurologic symptoms including back pain, radiculopathy or cauda equina. Magnetic resonance imaging is the most helpful dignostic means and should be used initially if suspected. Treatment is decompressive laminectomy and debulking of fat. MATERIALS AND METHODS: Two cases of lumbar epidural lipomatosis with neurologic symptoms were discussed and evaluated by physical examination, postmyelography CT and MRI. RESULTS: Two cases were treated with decompressive laminectomy and debulking of fat. Increased accumulation of the fatty tissue was seen predominently in posterior and posterolateral epidural space of the spinal canal, displacing and compressing the lumbar spinal cord anteriorly. Both gross and histologic evaluation revealed overgrowth of unencapsulated normal appearing fat consistent with spinal epidural lipomatosis. One case was demonstrated gradual improvement in symtoms after operation but the other was died due to medical problems. CONCLUSION: The authors reviewed the literature and reported the results of operative treatment of patients with lumbago, radicular pain and intermitent claudication caused by epidural lipomatosis of lumbar spine and degenerative spinal stenosis.

Hyperplasia*

Tretinoin(all-trans retinoic acid) is a metabolite of vitamin A and it is useful in the treatment of photoaging skin. Photoaging skin is characterized by wrinkles, mottled pigmentation, dry and rough skin, and loss of skin tone. Current use of topical tretinoin mainly acts on the epidermis, requires a long period to obtain the desired results and may cause skin hyperpigmentation. A combination of topical and injectable tretinoin has been used to reduce the treatment period as a result of its potentialized effect on the dermis when compared to graditional topical cream use. in this study, we observed histologic alterations in 5 white rabbits after using 0.05% topical tretinoin cream and 0.1% injectable tretinoin. Tretinoin was treated on the rabbits ears-group 1 and 2 on the right ear for study 1, and group A and B on the left ear for study 2. Study 1 was done to differentiate whether the dermal thickening is due to the simple physical stretching of dermis by intradermal injection, or whether it is duer to the histologic change by tretinoin. In group 1, saline was injected intradermally and in group 2, tretinoin was injected intradermally. Study 2 was done to compare the dermal thickening between the topical tretinoin cream treatment group (group A) and the combined topical and injectable tretinoin group (group B). Injection was done once a week immediately followed by 340nm blue light skin exposure. These treatment were done for 12 weeks. We harvested skin stripe from all group, group 1 and 2, and group A and B respectively, after 2, 6, and 12 weeks after treatment. Histologic differences were observed and measured. Dermal thickening was observed in group 2 and in group B(p<0.05). The results showed that intradermal injection of tretinoin mainly acts on the dermis and potentialtes the effect on photo-aging skin and fine wrinkles.
