  • Pulmonary sequestration occurs when some disturbance produces a cystic mass of nonfunctioning lung tissue which lacks normal communication with the tracheobronchial tree. Between 1971 and 1985, pulmonary sequestration was diagnosed in 11 patients, ranging age from 3 to 29 years. All sequestration were intralobar type. Definitive diagnosis can only be obtained by aortography and/or surgical exploration in 10 cases. The other one was confirmed by pathologic examination postoperatively. The presenting complaints were mostly recurrent local pulmonary infection, but in 2 cases mediastinal mass with respiratory symptoms was presented, and cardiac murmur was only finding in one case. Preoperative diagnostic procedure revealed 3 associated anomalies which were funnel chest, right aortic arch, and pulmonic stenosis with vascular ring. Operative treatment for sequestration was lobectomy in 10 cases, and a segmentectomy in one. There was no operative mortality, but 3 complications [empyema, B-P fistula, post-op bleeding] which were controlled by subsequent operations or conservative measure. Aortography is strongly advocated not only for its diagnostic value, but for its preoperative localization of the aberrant vessels that are the major concern to the surgeon.

  • Simple or complex defects in the lower leg, and especially in its distal third, continue to be a challenging task for reconstructive surgeons. A variety of flaps were used in the attempt to achieve excellence in form and function. After a long evolution of the reconstructive methods, including random pattern flaps, axial pattern flaps, musculocutaneous flaps and fasciocutaneous flaps, the reappraisal of the works of Manchot and Salmon by Taylor and Palmer opened the era of perforator flaps. This era began in 1989, when Koshima and Soeda, and separately Kroll and Rosenfield described the first applications of such flaps. Perforator flaps, whether free or pedicled, gained a high popularity due to their main advantages: decreasing donor-site morbidity and improving aesthetic outcome. The use as local perforator flaps in lower leg was possible due to a better understanding of the cutaneous circulation, leg vascular anatomy, angiosome and perforasome concepts, as well as innovations in flaps design. This review will describe the evolution, anatomy, flap design, and technique of the main distally pedicled propeller perforator flaps used in the reconstruction of defects in the distal third of the lower leg and foot.

  • Hyperimmunoglobulin E syndrome(HIES) is a primary immunodeficiency characterized by severe recurrent soft-tissue infections, pneumonias, pruritic dermatitis and markedly elevated serum IgE levels. Pneumatocele and empyema develop as result of recurrent pneumonias. It is inherited in an autosomal dominant fashion, with variable expressivity. We experienced the case of a 10 month old girl with hyper IgE syndrome. Patient was admitted for local ulceration and muscle soreness at the site of BCG inoculation. The diagnosis of hyper IgE syndrome was made because she had a coarse facial appearance, pruritic dermatitis, pneumatocele and markedly elevated serum IgE level with a past history of frequent skin abscess and pneumonia.

  • To improve signal-to-noise ratio in sodium image, short echo time (2-3 ms) and long data acquisition (10-20 ms) protocols are used. Sodium in biological specimens demonstrates a bi-exponential decay of transverse magnetization and the fast decaying component of the sodium signal results in the reconstruction of images which are blurred significantly. The spatially-dependent nature of the blurs are due mainly to the presence of short local transverse relaxation values (0.7-3 ms) of sodium in tissue. We present an algorithm that corrects for object-dependent blurs due to fast-decaying T2 and improves the computational behavior of the algorithm by incorporating a relaxation parameter into the iterative process.

  • A specific anthropomorphic mannequin (SAM) model was used to investigate the relation between local specific absorption rate (SAR) and head size. The model was scaled to 80 to 100% sized models at intervals of 5%. We assumed that the shell of the SAM model has the same properties as the head-equivalent tissue. Five handsets with a monopole antenna operating at 835 MHz were placed in the approximate cheek position against the scaled SAM models. The handsets had different antenna lengths, antenna positions, body sizes, and external materials. SAR distributions in the scaled SAM models were computed using the finite-difference time-domain method. We found that a larger head causes a distinct increase in the spatial peak 1-voxel SAR, while head size did not significantly change the peak 1-g averaged-SAR and 10-g averaged-SAR values for the same power level delivered to the antenna.

  • The herbal composition Gyeongshingangjeehwan 18 (GGEx18), which is composed of three herbs, Laminaria japonica Aresch (Laminariaceae), Rheum palmatum L. (Polygonaceae), and Ephedra sinica Stapf (Ephedraceae), has been used as an anti-obesity drug in Korean local clinics. Thus, we investigated whether GGEx18 regulates obesity by suppressing appetite in high fat diet-induced obese C57BL/6J mice. Administration of GGEx18 to obese mice for 9 weeks significantly decreased body weight gain, epididymal adipose tissue weight, and food efficiency ratio. GGEx18 also caused a significant decrease in the circulating levels of leptin, which were increased by about 450% in obese control mice compared with normal lean mice. Concomitantly, GGEx18 decreased mRNA levels of a potent appetite-stimulating hormone neuropeptide Y, but increased an appetite-suppressing hormone pro-opiomelanocortin mRNA levels. These results suggest that GGEx18 may prevent obesity through regulating appetite in nutritionally obese mice.

  • CVA is a kind of cerebrovascular disease which has a few local functional lesions of brain tissue, and it is generally caused by cerebral infarction, cerebral hemorrhage, and so on. It is also known as a stroke of paralysis, which leaves a lot of sequelae in a patient such as lesion of movement, perceiving, memory, sense, emotion, etc. A CVA patient which has a sequela, the sense disorder of equilibrium, took the Saam Acupuncture Therapy and Dr. Dong's Acupuncture Therapy, and then he was cured.

  • Malignant fibrous histiocytomas (MFHs) is the most common type of soft tissue sarcoma in the old animal with a aggressiveness, a high local recurrence rate and significant metastatic rate, which associated with a poor prognosis. In most histologic and immunohistological studies, the tumor cells raised from a fibroblastic and/or myofibroblastic phenotype, presumably from undifferentiated mesenchymal cell origin. MFHs are usually firm and invasive, arising in the subcutis; metastasis depends on tumor grade (many are grade 3) [1,2]. The primary tumor cells are pleomorphic, varying in appearance from fusiform to round. Often nucleoli are prominent and irregular [5]. Extracellular amorphous eosinophilic material may be prominent and likely represents reactive collagen production by the tumor [5]. (omitted)

  • Most interdigital neuroma can be diagnosed clinically. But, diagnostic local injection method, sonography and magnetic resonance image(MRI) have been used as secondary tests for clinical confirmation or surgery. Recently, there have been active discussions on the method of interdigital neuroma diagnosis for which sonography or MRI is used. For finding out the location or the number of interdigital neuroma particularly in non-typical clinical manifestation or surgery, MRIs, which are exellent in tissue contrast, may be quite helpful. This case had an interdigital neuroma showing non-typical manifestation. MRIs were used for clinical diagnostic confirmation and finding out the location and the number of interdigital neuroma. Thus, the validity along with literary consideration is being reported.
