1.Instability Patterns of Normal Midcarpal and Radiocarpal Joint in the Sagittal Plane.
The Journal of the Korean Orthopaedic Association 1998;33(3):528-534
The midcarpal joint has inherent instability in the sagittal plane. Several instability patterns of midcarpal joint due to ligament insufficiency have been presented. We ohserved the normal midcarpal and radiocarpal behaviors of ligament laxity in the sagittal plane to investigate the significance of dorsal and palmar stress test which has been used for evaluation of the non-dissociative carpal instahilities. We performed the dorsal and palmar displacement stress test on fifty pairs of normal wrist joints under the flouroscopic views. The midcarpal joints were subluxed, more on dorsal stress, with variable degrees. Dorsal subluxations in females and third decades were more prominent than males and fourth decades. Three types of radiocarpal instability on dorsal stress test could be observed. We think that displacement stress test in the sagittal plane should be interpreted in consideration of normal instability patterns in the evaluation of ahnormal midcarpal and radiocarpal instabilities since there are variable patterns and degrees of ligament laxity in normal wrist joints.

Despite the fact that benign skin lesions can undergo malignant transformation, the necessity and timing of the surgical resection have yet to be established. In this study, we analyse three cases of benign-appearing skin lesions, which were found to be carcinomatous on histologic examination and review the literature regarding the importance of prophylactic removal of benign-appearing skin lesion. The first and second cases were female patients wishing for cosmetic surgery. The first patient had a benign-appearing lesion on dorsum nasi, and the second patient had an inconspicuous lesion right along the right nasolabial fold. The third patient was a middle-aged male with a pigmented lesion on the left cheek, who presented to the clinic only after having met the operating surgeon through an acquaintance outside the hospital setting. All of the lesions were suspected to be of benign nature and were excised for cosmesis only. However, histologic examination of these lesions showed that the first two tumors were basal cell carcinoma with the last tumor being squamouse cell carcinoma. Thus, it is considered that removal of benign like skin lesion will result in good prognosis of patients scheduled to undergo other surgery.

We report two cases of cleidocranial dysplasia, which was managed without significant craniofacial osteotomy. A mother and daughter, both of normal intelligence, presented with central forehead depression, mid-face hypoplasia, and blepharoptosis. The fact that they have an identically deformed face implied a genetic basis. In both patients, radiologic evaluation revealed the underdeveloped maxilla, persistent fontanelle opening, and cleidal aplasia. Clinical findings and radiologic studies were consistent with the diagnosis of cleidocranial dysplasia. Both patients underwent forehead plasty via bicoronal approach, augmentation rhinoplasty using tip plasty, and epicanthoplasty. In addition, the mother underwent malar augmentation using Medpor implantation and reduction genioplasty. The patients did not experience any postoperative complication and remained satisfied with the operation at 6-year follow-up.

PURPOSE: Autologous platelet rich plasma (PRP) has been known to enhance tendon healing and improve tensile strength after tendon injury. This study investigated the dosage of PRP to increase the tensile strength. METHODS: PRP was harvested from peripheral bloods of the rabbits. Direct injury model was adopted using 60 achilles tendons in 30 rabbits. The autologous PRP was infiltrated into the Achilles tendon repair site of four groups (control, 0.1, 0.2, 0.4 mL) with different dosages. Tendons were harvested at 2, 4 and 8 weeks and subjected to measuring mechanical tensile strength and dosage of collagen content. RESULTS: At 2, 4, and 8 weeks, PRP administration following experimental achilles tendon repair resulted in an overall higher average tensile strength and collagen content compared to these of the control. Also, the lengthen the time, tensile strength and collagen content was increased. CONCLUSION: Autologous PRP enhanced tendon healing in rabbits. Within the PRP dosage setted by the author, more dosage of the infiltrated PRP increases the strength of the tendon and the dosage of collagen content. Further studies will be essential to determine the optimal dosage of PRP in clinical practice.

Behçet's disease is a systemic chronic disease that occurs in tissues such as eyes, joints, organs and nerves, and it has been noted that symptoms may be observed in a variety of tissues. In previous studies, reports of blepharoptosis observed in patients with Behçet's disease have been rare. We would like to report a case where a patient among those who visited our hospital with blepharoptosis had a history of Behçet's disease. This patient had been diagnosed with Behçet's disease, and complained of bilateral blepharoptosis even at the time of diagnosis. He complained of dysfunctions in vision and hearing, and upon eye examination, an eye movement disorder was found in his left eye. From the symptoms, neuro-Behçet's disease was diagnosed. The oculomotor and levator palpebrae superioris muscles are both controlled by cranial nerve III, which may suggest that Behçet's disease in this patient occurred in cranial nerve III. The patient received an oral steroid, and the symptoms have improved without surgery. Since we could identify the correlation between Behçet's disease and blepharoptosis, we considered that sharing this case and its outcome would be helpful for plastic surgeons who treat eyelids.

BACKGROUND: The nasal septal cartilage is often used as a donor graft in rhinoplasty operations but can vary widely in size across the patient population. As such, preoperative estimation of the cartilaginous area is important for patient counseling as well as operating planning. We aim to estimate septal cartilage area by using facial computed tomography (CT) studies. METHODS: The study was performed using facial CT images taken from 200 patients between January 2012 to July 2015. Using the mid-sagittal image, the boundary of cartilaginous septum was delineated from soft tissue using the mean difference in signal intensity (or brightness). The area within this boundary was calculated. The calculated area for septal cartilage was then compared across age groups and sexes. RESULTS: Overall, the mean area of nasal septal cartilage was 8.18 cm² with the maximum of 12.42 cm² and the minimum of 4.89 cm². The cartilage areas were measured to be larger in men than in women (p<0.05). The area decreased with advancing age (p<0.05). CONCLUSION: Measuring the size of septal cartilage using brightness difference is more precise and reliable than previously reported methods. This method can be utilized as the standard for prevention of postoperative complication.

Limb salvage operations for osteosarcoma of the extremity usually consist of wide excision and skeletal reconstruction. Most osteosarcoma patients are anemic prior to the surgery as majority of them undergo preoperative neo-adjuvant chemotherapy; thus, it is necessary to treat anemia before and after the surgery since limb salvage operation tends to accompany significant blood loss. Despite the fact that blood transfusion has bad influence on prognosis, complication, and postoperative outcome of cancer patients, it is still considered as a standard management to fix anemia for limb salvage operations. We would like to present a case report in which the authors succeeded in performing limb salvage operations on patients with distal femur osteosarcoma without transfusion.

The presence and distribution of pan-neuroendocrine markers such as neuron-specific enolase (NSE), chromogranin (CG), and synaptophysin (SYP) were investigated by immunohistochemistry in 15 cases of neuroblastic tumors, including four cases of neuroblastomas, six cases of ganglioneuroblastomas, and five cases of ganglioneuromas. Three cases of normal sympathetic ganglion were used for the normal control group. NSE was observed in all cases and both in ganglion cells and in neuropils. NSE was detected not only in the majority of the neuroblasts showing signs of differentiation, but also in some poorly differentiated neuroblasts. All cases of neuroblastic tumors were positive for CG, however, some variability of staining intensity and distribution patterns were noted. CG was found mainly in differentiated neuroblasts with enlarged cytoplasm and nuclei along the periphery of the perikaria, and was also found in the perinuclear regions of some undifferentiated cells. SYP was positive in 9 of 11 cases. In all of the 9 cases, SYP was detected in some differentiating neuroblasts and differentiated neuroblasts, as well as the mature ganglion cells. However, it has scarcely stained in dot or granular pattern. Two CG-negative tumors were also negative for SYP. Our data indicate that antibodies against NSE and CG are helpful as a diagnostic aid for neuroblastic tumors.
