  • An extremely unusual case of epidermoid cyst showing diffuse parakeratosis and aggressive clinical behavior is presented. A destructive bone lesion with surrounding ill-defined soft tissue lesion was found by computed tomography in a 63 year-old man complaining of painful swelling of the right buttock. He had a history of surgical excision twice for epidermoid cysts of soft tissue of the right hip during recent one year On aspiration cytology, the aspirate was highly cellular and mostly composed of desquamated nucleated squamous cells. Operation finding revealed that the iliac bone was Irregularly destroyed and filled with gray-white cheesy material and necrotic bone bedris. Adjacent gluteus muscle showed scattered gray-white lesions. The curettage specimen showed bone necrosis and desquamated squamous cells filling the marrow spaces. The lesion within muscle revealed epidermoid cyst with diffuse parakeratosis.

  • The objective of the study was to investigate the effect of feeding fibrous diets on growth performance and occurrence of aggressive behaviours in growing pigs. Sixty healthy castrated pigs (initial body weight: $46.7{\pm}4.35$ kg) were used. A basal diet was diluted with maize cobs to two levels (0 and 160 g/kg dry matter). Behavioural activities were observed using video cameras for three weeks, 8 h/d starting at 0800 h. Pigs subjected to control diet gained more weight compared to pigs receiving fibrous diet in week 1 (0.47 vs 0.15 kg, respectively) and 2 (1.37 vs 1.04, respectively) (p<0.05). Average daily gain was not affected by treatment diet in the third week. Pigs on high fibrous spent more time eating, lying down, standing, walking and fighting (p<0.05) compared to pigs on control diet. Time spent eating increased as the weeks progressed whilst time spent lying down decreased. Time of day had an effect on time spent on different behavioural activities exhibited by all pigs on different treatment diet (p<0.05). Inactivity was greatest in 5th (1200 to 1300 h) hour of the day for all the pigs on different dietary treatments. Skin lesions appeared the most on neck and shoulder region followed by chest, stomach and hind leg region, and finally head region (p<0.05). Pigs on high fibre diet had more skin lesions in all body regions compared to pigs on control diet (p<0.05). It can be concluded that the high fibrous diet with maize cobs did not affect growth performance and also did not reduce aggressive behaviours. Aggressive behaviours emanated out of frustration when queuing on the feeder. The findings of this study suggest that maize cobs can be included at a level of 160 g/kg in diets of pigs. However, to reduce the level of aggression more feeding space should be provided.

  • 공격성 섬유종증은 비교적 드문 연부 조직 종양이지만, 국소 증식 및 침윤성이 강한 종양으로 알려져 있다. 그렇지만 종양 증식에 관한 정확한 기전은 아직 보고되어 지지 않고 있다. 한편, 종양 억제 유전자 PTEN은 국소 침윤성과 전이를 보이는 여러 암 조직에서 발현의 감소 또는 돌연 변이가 보고되고 있다. 본 연구에서는 공격성 섬유종증에서 면역조직화학적 염색과 면역탁본법을 통해 종양 억제 유전자 PTEN의 발현의 양상을 알아보고자 하였다. 면역 탁본법과 면역조직화학적 염색상 PTEN의 발현은 정상 근막 조직에서는 균일하게 발현되었으나, 공격성 섬유종증 종양조직에서는 발현이 감소하였다. 공격성 섬유종증에서 PTEN발현의 감소는 급속한 증식과 재발 및 주위 조직의 침윤이 특징인 공격성 섬유종증의 병인에 관련이 있을 것으로 사료된다.

  • Fatigue crack growth rates(i.e. crack initiation and crack growth of short and long crack) are investigated using commercial plates of high strength Al alloy 7075-T651 for the transverse-longitudinal(T-L) direction in air, water and sea water. Also, the evaluation direct current potential drop(D.C.P.D) method and the fractographical analysis by SEM are carried out. Near threshold region, short crack growth rates were much faster than those of comparable long cracks, and these short crack growth rates actually decrease with increasing crack growth and eventually merge with long crack data. Fatigue crack propagation rates in aggressive media(i.e. sea water) increase noticeably over three times those in air. One of the most significant characters in this phenomenon as a corrosion-fatigue causes an acceleration in crack growth rates. Sea water environment, particularly Cl$^{[-10]}$ solution brings the most detrimental effects to aluminum alloy. The result of fractographical morphology in air, water and sea water by SEM shows obvious dimpled rupture and typical striation in air, but transgranular fracture surface in water and sea water.

  • Columnar cell variant of papillary thyroid carcinoma (CCV-PTC) is a rare variant representing 0.15-0.2% of all PTCs. The CCV is aggressive, due to its rapid growth, high local recurrence rate, and frequent lung, brain and bone metastasis. Aggressive surgical and medical management are recommended for these neoplasias. The authors experienced a case of CCV-PTC in a 45-year-old man. We performed total thyroidectomy with neck dissection. The patient received radiation and radioactive iodine therapy. There were no recurrences or complications in the following 24 months after the operation. The patient will closely undergo continuous follow up. We present the clinical characteristics, pathology, treatment, and prognosis of the tumor with a review of the literature.

  • Infection of a median sternotomy incision may result in a large, unsightly,unstable,and potentially fatal wound. During the past 8 years, 5 consecutive patients [ 4 male and 1 female ] had repair of infected sternotomy wound. We describe our current preferred techniques and the results we have achieved with them. As soon as the sternal infection was shown, operative wound was opened and irrigated more than 4 times a day with 0.5% Betadine iodine solution until the exudate became clean with no growth of bacteria. Operation was performed in one-stage, which consisted of aggressive debridement of the infected bone and muscle transposition. Reconstruction was with one-side or both pectoralis flaps in all patients and rectus abdominis in 2 patients. There was no mortality or morbidity within 30 days postoperatively. We conclude that early aggressive debridement and muscle transposition remain the treatment of choice for most patients with infected median sternotomy wounds.

  • Early, aggressive nutrition is an important contributing factor of long-term neurodevelopmental outcomes. To ensure optimal growth in premature infants, adequate protein intake and optimal protein/energy ratio should be emphasized rather than the overall energy intake. Minimal enteral nutrition should be initiated as soon as possible in the first days of life, and feeding advancement should be individualized according to the clinical course of the infant. During hospitalization, enteral nutrition with preterm formula and fortified human milk represent the best feeding practices for facilitating growth. After discharge, the enteral nutrition strategy should be individualized according to the infant's weight at discharge. Infants with suboptimal weight for their postconceptional age at discharge should receive supplementation with human milk fortifiers or nutrient-enriched feeding, and the enteral nutrition strategy should be reviewed and modified continuously to achieve the target growth parameters.

  • Relative to a fetus of the same gestational age, very low birth weight (VLBW) infants are more likely to be underfed and to undergo growth restriction during their early hospital stay. The current trend towards "early and aggressive" nutritional strategies in VLBW infants aims to overcome the early nutritional deficiency and thereby boost postnatal catch-up growth, simultaneously improving long-term neurodevelopmental outcomes. Although the minimum starting amino acid (AA) dose to prevent negative nitrogen balance is well established, the upper limit and the rate of increase of early AA doses are controversial. Most randomized controlled trials show that early and high-dose (target, 3.5 to 4.9 g/kg/day) AA regimens, with or without high nonprotein calories, do not improve long-term growth and neurodevelopment. High-dose AA supplementation may lead to early metabolic disturbances and excessive or disproportionate plasma AA levels, particularly in infants of very low gestational age. Further large studies are needed to clarify the optimal strategy for early administration of parenteral AA doses in VLBW infants.
