Desmoid tumor is a type of fibromatosis usually arise in deep musculo-aponeurotic structures, primarily of the trunk and extremities. It is characterized by proliferation of fibroblastic tissue and does not metastasize but may be locally aggressive. Eventhough the surgical margin reveals clean, recurrence often occurs. To analyze the extent of the tumor and homodynamic characteristics exactly, we performed IV bolus CT. Desmoid tumors show peripheral rim enhancement on early phase scan and more strong, central enhancement on late phase IV bolus CT, which reflects abundant fibroblastic components of the tumor. We report two cases of pathologically confirmed desmoid tumor performed IV bolus CT.

Several measurements were performed about 105 cases of normal stress A-P arthrographic findings in adult knee including discoid without tearing or osteoarthritis, those were selected from 166 cases examined arthrographicaliy under same technical condition due to suspicious internal derangement of the knee from October 1976 to March 1980. After stastistical analysis and comparative study about chondrai thickness, chondral index, meniscal size, meniscal index, intermeniscal distance, type of meniscus, communication between knee and proximal tibiofibular joint, following results were obtained. 1. Chondral thickness of normal articular cartilage was not related to joint size, but almost same value individually. Mean chondral thickness In P and P points was 2.90±0.63mm, 2.90±0.62mm, 2.93±0.64mm, 2.92±0.65mm in lateral, medial femoral condyle and lateral, medial tibial condyle in order. Age change was not seen statistically. 2. The size of meniscus was correlated nearly proportional with that of the joint. Mean lateral meniscus size (transverse meniscal length × meniscal thickness) was 12.55±2.50mm × 6.53±0.7mm in male and 10.13±2.25mm × 6.02±0.52mm in female. That of medial meniscus was 9.79+1.54mm × 5.85+ 0.45mm in male, and 7.72±1.64mm × 5.36±0.92mm in female. Age change was not seen statistically either. 3. Mean intermeniscal distance was 60.21x2.74mm in male, 53.34±3.31mm in female and occupied 83% in male, 82% in female of joint size each other. 4. In types of meniscus, normal type was 8.10%, infantile type dlscoid 12.4%, intermediate type 2.9%, primitive type 3.7% each other. 5. Communications between knee joint and proximal tibiofibular joint were seen in 24%.

There is increasing evidence that inactivation of tumor-suppressor genes can promote tumor growth. Retinoblastoma protein (pRb) is the product of the retinoblastoma gene located on chromosome 13q14. pRb negatively regulates cell growth when functioning normally. Mutational inactivation of the Rb gene has been observed in retinoblastomas, osteosarcomas and soft tissue sarcomas. Recently, several other human cancers have also been shown to carry abnormalities of the Rb gene. The potential role of the Rb gene in cutaneous squamous cell carcinomas (SCCs) and basal cell caicinomas (BCCs), has not been determined and was the focus of this study. Immunohistochemical expression of pRb in 16 cutaneous SCCs and 17 BCCs was examined. The expression of PCNA was studied in parallel to assess the cellular proliferation rate in these lesions. The pRb and PCNA immunoreactivity were localized to the nuclei of tumor cells. A few pRb and PCNA positive cells were seen in normal squamous epithelium, sebaceous glands, sweat glands and hair follicles. The loss of expression of pRb was seen in 3 of 16 SCCs(18.8%) and 6 of 17 BCCs (35.3%). PCNA immunoreactivity was slightly high in pRb-negative or lower-positive cases. PCNA immunoreactivity was similar to that produced by pRb in some cases. These results suggest that mutational inactivation of the Rb gene may be related to the carcinogenesis of cutaneous SCC and BCC, though the frequency is relatively low.

The latissimus dorsi muscle or musculocutaneous flap is one of the most useful flaps in reconstructive surgery. This flap has many advantages, such as its reliable anatomy, long pedicle with large caliber vessels, minimal functional deficit of the donor site, and low incidence of donor site complications. However, the bulkiness of the flap has been considered a disadvantage, so various modifications of technique have been devised. The cutaneous portion of the flap can be safely elevated based on the cutaneous perforating branch of the thoracodorsal vessel. From March 1997 to February 1998, 10 patients underwent reconstructive procedures with thoracodorsal perforator-based free flaps. The composition of the flaps varied in accordance with the nature of the defect. The variances in the flaps were as follows; 3 were cutaneous, 6 musculocutaneous, and 1 osteomusculocutaneous including the rib. All flaps survived with good contour. We concluded that this thin and reliable flap was useful for reconstruction of various defects, and that the composition of the flap, such as subcutaneous, muscle and bone, gave it considerable flexibility as needed.

Facial clefts are uncommon congenital deformities in comparison to the clefts of the lip and palate. the clinical expression of the craniofacial clefts is highly variable. the face can be marred by a faint expression of the cleft or be disfigured by a full representation of the defect. the extent of the soft tissue and skeletal components is also variable, and they are seldom affected to an equal degree. Generally, discription of the clefts are based on the bony malformation, since the skeletal landmarks tend to be more constant. I report six cases of rare craniofacial clefts that I recently experienced. the soft tissue repair was accomplished with local flaps from cheek, eyelid and nose. Additional vertical length was obtained from the lower Z-plasty flaps in the sutures. the coloboma was corrected with local flaps and a cartilage graft, the depression of cheek with a dermofat graft, and the macrostomia with the repositioning of orbicularls oris muscle and a Z-plasty. the results were cosmetically acceptable.

The reduction of nasal bone fracture has been done by a simple procedure. The nasal bone fracture was not a serious problem and patients are usually treated as outpatients. However it is causing increased demand for medical services far cosmetic reasons. We studied the nasal bone fracture by retrospective analysis, it comprising 606 patients with nasal bone fractures in various accidents and treated of Chonnam University Hospital from March 1995 to February 1998. We reviewed and analyzed the medical records and facial bone CT scans of 606 patients. The following results were obtained. 1. The prevalent age group was in the third decade, the most common cause was traffic accidents, while nasal swelling, tenderness, nasal deviation and crepitation were examined 2. The classification of nasal bone fracture was done by facial bone CT. Class 1: Nasal tip depressed fracture(16%) Class 2: Displaced nasal bone fracture without depression(30%) Class 3: Displaces nasal bone fracture with depression(12%) Class 4: Comminuted nasal bone fracture (10%) Class 5: Simple fracture of nasal bone and frontal process of maxilla(14%) Class 6: Comminuted fracture of nasal bone and frontal process of maxilla(11%) Class 7: Nasal bone fracture without displacement(9%) .

Apgar score is most widely used evaluating indicator of newborn health, but it is very subjective. Umbilical cord blood gas analysis is more objective and effective than Apgar score in evaluation of newborn status. Cord blood gas was changed slightly by processing of time after fetal birth. This study was undertaken to observe objectiveness and effectiveness of umbilical arterial blood gas analysis and effects of time interval of cord clamping to newborn health with 122 pregnant women and their babies. We observed following results: 1. There were poor correlation between Apgar score and umbilical cord arterial blood analysis in evaluating of newborn health (P>0.05). 2. There was no clinical significance of Apgar score or umbilical arterial blood gas analysis as single indicator in evaluating of newborn health (P>0.05). 3. Gas analysis and pH of umbilical arterial blood was more helpful in evaluating of newborn health than Apgar score. 4. There were no significant effects of time interval of umbilical cord clamping to newborn health. 5. If there were no indications of early umbilical cord clamping, cord blood sampling at immediately after birth without cord clamping was more effective to evaluate newborn status.

Two types of urine dipstick assays, Multistix-SG and Comber-9-Test RL, were compared for compatibility, accuracy, specificity and predictive values of a positive and negative test in 501 patients' urine and artificially prepared specimen. We found that the results of semiquantitative tests of Multistix-SG and Comber-9-Test RL performed were statistically similar in patients' specimen. The urinary leukocyte esterase tests of Comber-9-Test RL assays compared with urine sediment microscopy in regard to compatibility, sensitivity, specificity, and predictive values of a positive and negative test 83.7%, 48.1%, 90.3%, 47.4% and 90.1%, respectively. The urinary nitrite tests of Comber-9-Test RL assays compared with urine culture tests, in regard to compatibility, sensitivity, specificity, and predictive values of a positive and negative test were 90.3%, 19.4%, 84.7%, 53.8% and 94.1, respectively. For the urinary protein, the sulfosalicylic acid method was the most sensitive test for any kinds of protein, and Multistix-SG appeared more sensitive than Comber-9-Test RL for the albuminuria. For the urinary bilirubin and glucose, two dipstick assays were similar in their diagnostic efficiency. Finally in the urinary occult blood tests, Comber-9-Test RL assays was more sensitive than Multistix-SG.
