To evaluate the possibility of the newly developed highly porous glass ceramics as a space-filler in the cavitary bone defect, we made the opening sized 1 × 0.5 cm on the medial aspect of the right proximal tibia of nine rabbits. We impacted the highly porous glass ceramics firmly to the medullary cavity of rabbit tibia through the opening. Each three were sacrificed at 4th, 8th, and 12th week and analyze in vivo reaction of the glass ceramics in rabbit tibia with radiological and histological methods. On radiological examination, radiolucent line was seen around impacted glass ceramics at 4th week, but this radiolucent line was obliterated gradually to 12th week. On histological examination, new bone formation with osteoblast was appeared at 4th week without foreign body reactions. At 8th week, newly formed bone infiltrated into the porous space between glass ceramics particles was noticed, and the surface of glass ceramics was tightly bound by newly formed bone with osteoblastic rim and mature bone, At 12th week, the amount of newly formed mature bone increased, though there was on evidence of resorption of glass ceramics particle. So, we suggest that the highly porous glass ceramics is one of the possible artificial bone graft substitutes, especially as a space-filler.

Bartter syndrome is a renal tubular defect in electrolyte transport characterized by hypokalemia, metabolic alkalosis, hyperreninemia, hyperaldosteronism, normal blood pressure, and other clinical symptoms. As a clinical and genetical heterogeneous disorder, this syndrome can be classified into two clinical variants, antenatal Bartter syndrome and classic Bartter syndrome according to the onset age. Nephrocalcinosis is common in antenatal Bartter syndrome, but is rare in classic Bartter syndrome. It can also be classified into five genetic subtypes by the underlying mutant gene, all of which are expressed in the tubular epithelial cells of the thick ascending limb of the loop of Henle. Patients with Bartter syndrome type 1, 2 and 4 present at a younger age than classic Bartter syndrome type 3. We have experienced a case of Bartter syndrome with nephrocalcinosis in a 42-year-old woman diagnosed by biochemical and radiologic studies. We had successful response with potassium chloride and spironolactone.

BACKGROUND: The gut is an important area for inflammatory responses. Gut manipulation during open laparotomy compared with laparoscopic surgery, increases the inflammatory responses. Laparoscopic assisted colectomy (LC) with less bowel manipulation might minimize the inflammatory responses and oxidative stress, and offer a faster postanesthetic recovery than an open colectomy (OC). This study evaluated the effect of N-acetyl-cysteine (NAC), an antioxidant, on the recovery after colectomy. METHODS: 116 colorectal tumor patients were reviewed retrospectively. The patients were divided into 3 groups; LC by surgeon A (A - L), OC by surgeon A (A - O) and OC by surgeon B (B - O). The postanesthetic recovery scores (PARS) were compared. In the prospective randomized controlled trial, the colorectal tumor patients were assigned to one of four groups; laparoscopic assisted colectomy (L - N) with NAC infusion (L + N), open colectomy (O - N) with NAC infusion (O + N). In the NAC groups, NAC (5 mg/kg/h) was infused after intubation to extubation. The PARS were compared. RESULTS: In the retrospective study, the time to reach 10 points, which satisfies the discharge criteria in the PACU, was significantly lower in the A-L group than in the other groups. In the prospective study, the time to 10 points was shorter in the O + N group than in the O-N group. NAC offered no added benefits to the L + N and L-N groups. CONCLUSIONS: NAC offered faster recovery in the OC group but not in the LC group.

Vibrio vulnificus infects susceptible individuals who eat contaminated seafood or have an open wound that is exposed to seawater. The common symptoms are necrotizing wound infection, primary septicemia, and gastroenteritis. A 52-year-old man visited the emergency department complaining of drowsiness. Based on a cerebrospinal fluid analysis, he was diagnosed with acute bacterial meningitis. V. vulnificus was isolated from a blood culture. The patient responded to treatment with ceftriaxone and ciprofloxacin. We report a rare case of acute bacterial meningitis caused by V. vulnificus that was treated successfully.

Scedosporium(S.) apiospermum has been isolated from polluted water, soil, sewage and potted plants in a hospital with low virulence. The localized skin infection due to S. apiospermum is rare and usually results from traumatic implantation of contaminated material due to a penetrating injury. We report a case of skin infection due to S. apiospermum in a 78-year-old female. She had multiple nodules, pustules and exudative ulcerative lesions at the right forearm. Cultured isolation for definitive diagnosis showed typical S. apiospermum. Treatment was started with itraconazole effectively, but skin lesions were recurred after 4 months, and then cured with voriconazole with no recurrence.

An ultrasonographic examination revealed increased fetal bladder size and decreased AFI as well as fetal bilateral hydronephrosis at 173weeks' gestation. Diagnosis of the fetal posterior urethral valve syndrome was made. Percutaneous fetal bladder puncture with aspiration and amniocentesis was performed. The fetus was normal male karyotype and with a predicted good renal function(sodium concentration, chloride concentration, and osmolarity at 74 mEq/L, 60 mEq/L, and 148 mOsm, respectively). So, the fetus underwent amnioinfusion and vesico-amniotic shunting procedure (VASP) using a double-basket catheter at 194weeks' gestation in order to prevent development of dysplastic kidneys and hypoplastic lungs. The healthy male baby was delivered at 384weeks' gestation and had normally functioning kidney. Cutaneous vesicostomy was performed for the newborn since the urethral orifice was small. The one year old infant is now well and waiting for urethroscopic valve ablation procedure.
