Background. Ever since the first report of deltopectoral flap in pharyngo-esophageal reconstruction in 1965, various methods of flap reconstruction have been introduced, allowing surgical eradication of tumors that were once thought to be inoperable. Despite these advancement, many literatures emphasize distant metastasis and second primary malignancies as the most important factors that contribute to the low 5-year survival rate of the patients. Specific consensus about defining second primary cancer is still debatable, due to small number of reports regarding second primary tumors arising in flaps used for reconstruction of defects in the head and neck region. Case. We report a case of a 72-year-old male patient who, under the diagnosis of hypopharyngeal cancer, underwent total laryngectomy with partial pharyngectomy, extended right radical neck dissection with extended left lateral neck dissection, right hemithyroidectomy and radial forearm free flap reconstruction on June 16, 2003. After 37 cycles of radiation therapy, the patient exhibited no sign of recurrence. The patient revisited our department on June 14, 2016 with chief complaint of dysphagia that started two months before the visit. Radiologic studies and histology revealed squamous cell carcinoma in neopharynx, one that had been reconstructed with forearm free flap. Conclusion. Until now, only a handful of reports regarding patients with second primary cancer in reconstructed flaps have been described. Despite its rarity, diagnostic criteria for second primary cancer should always kept in consideration for patients with recurred tumor.

Background. Lymphoma of the vocal fold is extremely rare due to low lymphoid content in the larynx. To date, fewer than 100 cases of laryngeal lymphoma have been reported; however, none of these literatures are concerned about exclusive laryngeal involvement of recurred lymphoma which initially appeared in other body sites. Specific consensus about management for these patients yet to exist, due to its rare occurrence; however, the main modality of treatment is chemotherapy alone or in combination with radiation therapy. Case. Herein, we report a case of a 51-year-old female patient who had recurrent T-cell lymphoma developing in bilateral vocal folds. The patient was originally diagnosed of T-cell lymphoma in right colic flexure 10 years ago, and was cured by chemotherapy. Immunohistochemical stain revealed the histologic type of recurred tumor in the vocal folds that are identical to the previously cured lymphoma. Conclusion. To the best of our knowledge, this was the first case that recurrent lymphoma occurred solely in the vocal folds. Despite its rarity, lymphoma should be put in the index of suspicion among those patients with decreased vocal fold mucosal wave without definite vocal fold mass who had a history of cured lymphoma.

Purpose: Many causes for triggering or locking of the fingers have been discussed in other literatures. The most common one is known stenosing tenosynovitis, which causes, a mismatch between the volume of the flexor tendon sheath and its contents. However, repeated trauma to the hand is uncommon cause of trigger finger. Therefore, we present a case of a rare condition of stenosing tenosynovitis which developed from a repeated relatively weak superficial flexor tendon injury. Methods: The patient was a 62-year-old woman who showed a painless, fixed and round mass on her right hand with no particular cause. Active and passive range of motion of the metacarpophalangeal joint of long finger was limited in flexion and extension. Ultrasonographic finding showed injured flexor digitorum superficialis tendon had fibrillar architecture with swelling between hyperechoic synovial membrane and hypoechoic surrounding area. Surgical exploration revealed that a bunched portion of the flexor digitorum superficialis and A1 pulley cause triggering during operation after adhesiolysis of scar tissue. Results: After releasing the A1 pulley, the range of motion of the metacarpophalangeal joint of long finger showed no limitation and histological examination of the subcutaneous tissue revealed fibrous fatty degeneration. In this case, releasing the A1 pulley with adhesiolysis of the subcutaneous scar tissue was successful and we obtained good functional outcome. Conclusion: We examined a patient in whom a repetitive impact forces to the palm caused longitudinal tear of the flexor tendon, leading to trigger finger. We experienced a rare case of stenosing tenosynovitis and trigger finger caused after close injury to flexor digitorum superficialis and its degenerative changes that caused mass like effect. To the best of authors' knowledge, our case of close injury to the flexor digitorum superficialis and unique morphologic change before rupture of tendon is rarely to be reported.

Although the incidence of tuberculosis has been decreased, it is still an important community acquired infectious disease in the world. Miliary or disseminated tuberculosis occurs from the inadequacy of host defense in controling tuberculous infection. Generally, brain parenchyme has been considered to be a rare involving organ than other organs or meninges in miliary tuberculosis. However it has been proving that the brain parenchyme is commonly involved organ in miliary tuberculosis even without neurological manifestations. We report a case of 8 yr-old male patient, who was diagnosed as having an miliary tuberculosis with multiple tuberculoma throughout the brain. The tuberculous lesions of lung and brain were nearly cleared within 3 months with anti-tuberculous therapy. With a reveiw of related literatures, we suggest that the patients with miliary tuberculosis should be evaluateded about brain involvement.

There could be several methods for trochanteric reconstruction including local flap, pedicled perforator flaps, free flap, etc. We performed greater trochanteric reconstruction with lumbar artery perforator free flap in some aberrant method. So we report this experience with review of literatures. A 42-year-old man visited our hospital with a large soft tissue defect in his left greater trochanteric area by traffic accident. The patient had wide skin and soft tissue defect combined with open femur fracture. During one month period of admission, he underwent femur open reduction and wound debridement four times. After that we planned thoracodorsal perforator free flap reconstruction. The flap was outlined as large as $20{\times}15\;cm$ and elevated in a suprafascial plane from the lateral border. During intramuscular perforator dissection, we found that two 1.5 mm diametered perforator vessels coursed inferomedially toward second lumbar region. Finally the flap became lumbar artery perforator flap based on second lumbar artery perforator as a main pedicle. After flap transfer, the perforator vessels were connected with inferior gluteal artery and vein microsurgically. The operation was successful without uneventful course. We found no significant postoperative complication and donor site morbidity during six months follow up periods. Lumbar artery perforator flap could be an alternative procedure for thoracodorsal perforator flap in some patients with anatomic variant features.

We analyzed $3^{rd}$ graders' images of scientists and science learning students. We chose $3^{rd}$ graders because this is the time when children first encounter formal science learning opportunities. Draw-A-Scientist-Test (DAST) and the revised Draw-A-Scientist-Test Checklist (DAST-C) were used to analyze students' images of scientists, whereas Drawing-A-Science-Learner- and a checklist were used to analyze students' images of science learning students. We found that $3^{rd}$ graders showed common features of scientists who wore laboratory coats but not wearing glasses, goggles or masks and smiling. While most boys drew a male scientist, about a half of girls drew female scientists. Old and weird looking images of scientists that were typically known in other literatures were not found in this study. Science learning students were not wearing lab coasts, glasses, goggles, nor masks. Most of those students were conducting chemistry related experiments, which seemed to be influenced by the $3^{rd}$ grade's science curriculum. We also found relationships among components of images of scientists and science learning students. Although $3^{rd}$ graders' images of scientists and science learning students showed common features, this typical image was not the same as the previous studies have reported. This implies that the images of scientists and science learning students have not yet fixed by $3^{rd}$ grade. Thus, this seems to be a critical time when children start developing images of scientists. Children's direct experiences in the science classroom along with environmental factors such as media exposures can influence their formation of images of scientists and science learning students.

Objectives: The study is aimed to utilize Taesikbub and Lung-doyinbub described in "Dong-Ui-Bo-Gam" as a Korean Traditional Pulmonary Rehabilitation Exercise. Methods: We preliminary researched pulmonary rehabilitation exercise using domestic and international databases and old literatures of Korean Medicine. Then made a draft of Korean Traditional Pulmonary Rehabilitation Exercise based on "Dong-Ui-Bo-Gam". After organizing expert group for verifying the draft of the exercise, we developed the final Korean Traditional Pulmonary Rehabilitation Exercise. Results: The Korean Traditional Pulmonary Rehabilitation Exercise is composed of 5 actions including breathing method, flexibility exercise, percussion and hitting teeth. This exercise is recommended twice a day for at least 5 days per week under the supervision of specialist. It is expected to improve physical activity, dyspnea, health-related quality of life (HRQoL) as well as psychiatric symptoms by breathing deep and slow and exercising the thorax and upper limb muscles. Conclusion: Taesikbub, Lung-doyinbub in "Dong-Ui-Bo-Gam" may be suggested as a better pulmonary rehabilitation exercise for patients of chronic lung disease.

Antiphospholipid syndrome is a thrombotic disorder characterized by the association of arterial and venous thrombosis with the antibodies directed toward phospholipids. The presence of these antibodies in systemic lupus erythematosus(SLE) has been shown to be related to several clinical and analytical alterations. We experienced one case of lupus nephritis with positive antiphospholipid antibodies in a 10-year-old girl whose chief complaint was persistent microscopic hematuria. We report this case with a brief review of related literatures. (J. Korean Soc Pediatr Nephrol 2001 ;5 : 219-24)
