Blood valproic acid levels were decreased in patients with traumatic brain injury who had been using valproic acid to control irritability and aggression, and the symptoms worsened coincident with the administration of meropenem, a carbapenem-based antibiotic. Two weeks after the discontinuation of meropenem, valproic acid levels were restored to an effective therapeutic concentration. Therefore, when valproic acid and carbapenem-based antibiotics are used together, blood valproic acid levels may decrease due to drug interaction, and irritability symptoms may worsen. Thus, close monitoring of serum valproic acid levels is required.

PURPOSE: To report the first case of Waardenburg syndrome type 4 in Korea. CASE SUMMARY: A 3-year-old boy visited our clinic to have his abnormal right eye iris color checked. The patient had a previous operation Hirschsprung's disease. In addition, his older sister and aunt showed similar ocular findings. A general physical examination, hearing test, and fundus examination were performed. On examination, hypochromic heterochromic iridum, albinism of the posterior pole upon ipsilateral fundus, and dystopia canthorum were found. There was no abnormal finding in the hearing test. CONCLUSIONS: The patient showed hypochromic heterochromic iridum, dystopia canthorum, and albinism of ipsilateral fundus. He also had a family history of Waardenburg syndrome and had surgery associated with congenital megacolon. The patient was diagnosed with Waardenburg syndrome type 4.

Multiple symmetrical lipomatosis (MSL), also called Madelung's disease, is a rare disorder of unknown etiology and characterized by abnormal accumulation of large subcutaneous fatty masses in neck, shoulder, and upper trunk. MSL has known to predominantly affect middle-aged men with a history of alcoholism. Although the clinical course of MSL is considered to be slowly progressive, in advanced stage, fatty masses in the neck may compress the upper aerodigestive tract, resulting in dyspnea and dysphagia. The treatment of MSL is surgical resection, but radical excision is very difficult and recurrence after surgery is frequent. We report the case of 55-year-old man with long lasting MSL, which caused severe airway obstruction. This patient was admitted with progressive dyspnea and massive accumulation of fat around the vocal cord that was detected on a neck CT scan. This abnormal fatty infiltration in supraglottic region caused upper airway obstruction.

Numerous experimental and clinical studies of brain metabolism have reported since last two decades and many authors have concentrated their efforts on the metabolism of gas, glucose, electrolytes and enzymes. Oxygen and glucose that are utilized in the brain are two of the most important substances and play very important roles in the brain to form high energy bond(adenosine triphosphate) and nucleic acid. Authors have attempted to measure oxygen consumption in normal rabbit brains and diseased brains that are produced the expansion of stalk of laminaria in the right epidural space of the rabbit. In the normal rabbits, the average value of oxygen consumption of cerebral gray and white matters were 3.44+/-0.29---lO2/100 mg(dry weight)/30 min and 0.72+/-0.04---lO2/100 mg(dry weight)/30 min respectively. The value of oxygen consumption of cerebral gray and white matters in the compressed hemisphere showed high values than those in control group, and they revealed a tendency of rather rapid increase at an early experimental stage, and of gradual decrease thereafter.

PURPOSE: We investigated whether endothelial progenitor cells (EPCs) and vasculogenic factors are involved in the pathogenesis of pterygium and the mechanism underlying the selective recruitment of EPCs during this process. METHODS: We studied 13 normal controls and 28 pterygium patients [ primary (n=15), recurrent (n=13)]. Substance-P, vascular endothelial growth factor (VEGF), and stem cell factor (SCF) were measured in plasma and tears using ELISA, and circulating CD34+ and c-kit+ mononuclear cells (MNCs) by flow cytometry. Anterior segment fluorescein angiography (FAG) was performed to evaluate hypoxic conditions in the early stage of pterygium. Surgically removed pterygial tissues were analyzed immunohistochemically using the progenitor cell markers, CD34, c-kit, VEGFR-1 and VEGFR-2. RESULTS: Anterior segment FAG findings showed an increase in non-perfusion areas and attenuated vessels in the nasal limbus during early stage pterygium. Circulating CD34+ MNCs and c-kit+ MNCs were increased in pterygium groups compared with normal controls. Systemic and local cytokines including SP, VEGF and SCF in pterygium groups were also elevated and showed positive correlations with CD34+ and c-kit+ MNC numbers. Immunohistochemical analysis of pterygium showed strong progenitor cell marker immunoreactivities. CONCLUSIONS: EPCs might be involved in pterygium development, and ocular hypoxia triggers this neovascualrization by recruiting EPCs derived from the bone marrow via the production of systemic and local cytokines.

Bone marrow derived progenitor cells were reported to be involved in the pathogenesis of pterygium and have been suggested to be important in angiogenesis and the repair process after tissue damage. In order to investigate the involvement of these cells in wound healing after a pterygium excision, immunohistochemical staining was performed with a temporary amniotic membrane, applied to the bare sclera, after a pterygium excision using various progenitor cell markers, including CD34, c-kit, STRO-1, and AC133, to determine the expression levels of the participating cells. CD34-positive cells were observed along with some round or spindle-shaped mononuclear cells on the stromal side of the amniotic membrane. Some CD34-positive, large, and round or spindle-shaped cells formed clusters resembling small vessels in some regions of the amniotic membrane. c-kit was expressed in the epithelium that had grown over the amniotic membrane and in the spindle-shaped or round mononuclear cells in the stroma. Many stellate- to spindle-shaped fibroblast like cells expressed STRO-1, and AC133 was expressed in some round and ovoid cells. Overall, these results suggest that adult bone marrow- derived progenitor cells, such as endothelial progenitor cells and mesenchymal stem cells, are involved in the wound healing process post-excision in patients with pterygium.
