Alpasia cutis congenita is an anomaly characterized by absence of localized areas of the integument. The most common type of aplasia cutis congenita is Aplasia cutis congenita limited to the scalp, although other areas of the body may also be involved. We experienced a case of aplasia cutis congenita in a male newborn infant. The skin defects were extensive with symmetrical involvement of lower extremities. The multiple bullae were found on the both fingers and toes. No similar conditions and other associated congeital anomalies were found in the family membes of this particular case. The light microscopic examinaton of the denuded skin areas how absence of epidemis and the demis contain atrophic and hypoplastic adnexa. The bullae have a split within the dermis below lamina densa on electron microscopy. The skin defects were healed by supportive therapy for 4weeks.

PURPOSE: The aim of this study was to evaluate the utility of contrast-enhanced MRI with first-pass and delayed images in prediction of myocardial viability after acute myocardial infarction. MATERIALS AND METHODS: Ten patients (M:F=:4, mean age =6 5 years) with acute myocardial infarction underwent first-pass image after bolus injection of gadolinium (one image/sec for 120sec)and delayed image (7 2 minutes later). According to 60 segments on midventricular level, the assessment of MRI were concerned about location of lesion, depth of lesion, enhancement on first-pass image and enhancement pattern on delayed image. MRI findings were compared with wall motion on resting echocardiography and stress or follow-up echocardiography. RESULTS: 1) MRI findings were classified into 4 types: normal enhancement on first-pass and delayed images (type 1), normal enhancement on first-pass image and nontransmural hyperenhancement on delayed image (type 2), non-transmural enhancing defect on first-pass image and transmural enhancement with endocardial non-enhancing defect on delayed image (type 3), and transmural enhancing defect on first-pass image and transmural hyperenhancement on delayed image (type 4).2) Type 2 suggested viable myocardium and type 3 had high porbability of viability. Type was compatible with non-viable myocardium. CONCLUSION: Enhancing defect on first-pass image and involving thickness on both the first-pass image and delayed image in contrast enhanced MRI may predict myocardial viability.

Purpose:
To investigate the effects of simultaneous soft and hard tissue augmentation and the addition of polydeoxyribonucleotide (PDRN) on regenerative outcomes.
Materials and Methods:
In five mongrel dogs, chronic ridge defects were established in both mandibles. Six implants were placed in the mandible, producing buccal dehiscence defects. The implants were randomly allocated to one of the following groups: 1) control: no treatment; 2) GBR: guided bone regeneration (GBR) only; 3) GBR/PDRN: GBR+PDRN application to bone substitute particles; 4) GBR/CTG: GBR+connective tissue grafting (CTG);5) GBR/VCMX: GBR+soft tissue augmentation using volume stable collagen matrix (VCMX); and 6) group GBR/VCMX/ PDRN: GBR+VCMX soaked with PDRN. The healing abutments were connected to the implants to provide additional room for tissue regeneration. Submerged healing was achieved. The animals were euthanized after four months. Histological and histomorphometric analyses were then performed.
Results:
Healing abutments were gradually exposed during the healing period. Histologically, minimal new bone formation was observed in the dehiscence defects. No specific differences were found between the groups regarding collagen fiber orientation and density in the augmented area. No traces of CTG or VCMX were detected. Histomorphometrically, the mean tissue thickness was greater in the control group than in the other groups above the implant shoulder (IS). Below the IS level, the CTG and PDRN groups exhibited more favorable tissue thickness than the other groups.
Conclusion
Failure of submerged healing after tissue augmentation deteriorated the tissue contour. PDRN appears to have a positive effect on soft tissues.

A 77-year old man presented with a fungating mass on the oral mucosa and lip, which had an irregular margin. An incisional biopsy of the mass revealed an invasive squamous cell carcinoma. PCR analysis detected HPV DNA in the biopsy specimen. The HPV type was determined as HPV-53 by direct cycle sequencing. This is the first report of HPV-53 in an oral malignant tumor.

OBJECTIVES: The early detection of ectopic tubal pregnancy in unruptured state is increased as the transvaginal sonography and sensitive serum hCG test are available. For this unruptured tubal pregnancy, the medical treatment using methotrexate via various routes and dosage is being tried. Our study was to evaluate the efficacy of single systemic injection of methotrexate in the treatment of unruptured tubal pregnancies. Material and METHODS: From the January 1997 to July 1999, of 152 ectopic pregnancy patients, 22 patients who were diagnosed as unruptured tubal pregnancies were treated with single-dose systemic methotrexate injection (50 mg/m2/IM). Exclusion criteria were unstable vital signs with hemoperitoneum, adnexal mass > 5-6 cm. Serum hCG titers were checked before injection and 4, 7 day after injection. If serum hCG titer declined more than 15% on 7 day after injection compared with titer on 4 day, the weekly hCG titer was followed until it was <10 mIU/ml .If the hCG titer did not decline more than 15 %, a second dose was given. If hCG titer was not decreased or vital signs became unstable after 1-2 injections, the treatment was considered failure and surgery was done. RESULTS: 18 cases (82%) of 22 were successfully treated with single-dose methotrexate. The mean size of ectopic mass and initial serum hCG titers were 2.7+/-1.3 cm (range, 1.5-5.4 cm) and 3,298+/-1,007 mIU/ml (range, 132-12,239), respectively. Of 22, 6 cases (28%) needed second dose of methotrexate. The mean time to resolution of serum beta-hCG titer was 27.5+/-13.6 days (range, 8-53 days). Elevation of liver enzyme did not occurred in all cases during treatment. Initial hCG titer was more important prognostic factor than ectopic mass size for successful medical treatment. CONCLUSION: Single-dose methotrexate appears to be an effective medical treatment for the unruptured tubal pregnancy. However, patients selection using strict criteria is needed to increase its success rate.

OBJECTIVE: The aim of this study was to compare the serum brain-derived neurotrophic factor (BDNF) in acute depression with that in chronic depression. METHODS: Eighty subjects who met criteria for major depressive disorder (MDD) were recruited. Patients experiencing at least their fourth episode or an episode of at least 24 months in duration were defined as chronically depressed (n=21). Other patients were classified as acutely depressed (n=59). Antidepressant medications were administered for 6 weeks. Serum BDNF and Hamilton rating scale for depression (HAM-D) scores were measure before and after the administration of medication. RESULTS: We found significant differences in serum BDNF between the two groups. Serum BDNF was significantly higher among those with chronic depression than among those with acute depression both at baseline and after medication. CONCLUSION: This study suggested that serum BDNF might constitute a potential biological marker for chronic depression.
