This presentation is a case of osteomalacia, the cause of which was a nutritional deficiency. The patient was a 42-year-old female who had pseudofractures of ribs, ulnae, pelvic raml, the right second metacarpai bone and both femoral necks. Following treatment by medication combined with internal fixation of the femoral necks, the result was good.

We report a case of primary cardiac angiosarcoma in a 35 year-old woman. She presented with dyspnea, facial edema and neck vein distension during 1 month. The oval round large mass(8x4 cm) filling the right atrium infiltrated into the entire thickness of the lateral wall and extended to the vena cava and ventricle. The interatrial septum and pericardium seemed to be intact. Despite the surgical excision and adjuvant chemo-and radiotherapy, the patient died 8 months later due to tumor recurrence. The histologic findings of tumor varied from benign looking capillary proliferation mimicking granulation tissue to sarcoma composed of spindle cells. But anastomosing vascular channels lined by anaplastic polygonal cells and intracytoplasmic lumen containing red blood cells were characteristic findings. These tumor cells showed positive reaction to endothelial cell antigen and factor VIII-related antigen. The intercellular junctional complex and vascular channels formed by cytoplasmic process of tumor cells were identified by the ultrastructural study.

The gross tissue specimens are a valuable aid to the teaching of pathology and anatomy. However, traditional methods for storage and handling of them are discouragingly difficult and, recently, minimal surgical resections as well as preoperative interventions make it more difficult to have instructive gross specimens. Plastination is a process of tissue preservation by impregnation with silicone polymers or epoxy resins. The process in our study involves dehydration by cryosubstitution in aceton, defatting, forced impregnation of silicon polymer in a vacuum, curing and finishing. We submitted 40 surgically resected specimens to plastination. The resulting specimens are odorless, relatively dry, durable, life-like, non-hazardous, maintenance-free, and do not deteriorate with time. Plastinated specimens are a useful adjunct to the teaching of pathology, particularly suited for use in small groups, and appropriate method of tissue preservation. They are much preferred to wet preparation and conventional pots by both students and teachers owing to their accessibility, superior illustrative powers, and comparative ease of interpretation.

Neonatal Gaves disease is a relatively rare condition due to transplacental passage of Thyroid-stimulating antibody(TSAb) from a mother with active or inactive Graveses disease or autoimmune thyroiditis. A 11-day-old female newborn was referred to our department of pediatrics from a local clinic because of low level T4(3.55microg/dl) concurrent with high level TSH (501.74uIU/ml) on the 5th day neonatal metabolic screening. But, our repeated laboratory data showed very high serum T4(59.6microg/dl), T3(1,600ng/dl), suppressed TSH(0.43uIU/ml), and the presence of TSH receptor antibody. Her mother was treated with propylthiouracil(PTU) for Graves disease during pregnancy. Therefore, we thought it was a delayed-onset neonatal hyperthyroidism, because the fetal thyroid gland was initially suppressed by antithyroid drug taken during pregnancy. After initiating antithyroid drug therapy for the hyperthyroid nature, TSH levels became elevated again, while thyroid hormone levels decreased. Maternal and infant blood samples at the 23th day after birth were examined for serum autoantibodies directed towards the TSH receptor(Thyrotropin-binding inhibitory immunoglobulin:TBII, Thyroid-stimulating antibody:TSAb, Thyroid-stimulating blocking antibody:TSBAb) and high levels of TBII and TSAb were detected. About 2 months after birth, TBII and TSAb decreased within normal limit, and then we could stop antithyroid medication in safety. We report here a case of neonatal Graveses disease with very high level of T4 and T3, but firstly presented as hypothyroid nature on neonatal screening because of the maternally transferred antithyroid drug, PTU.

BACKGROUND: In cardiac surgery, hypothermia is associated with a number of major disadvantage, including its detrimental effects on enzymatic function, energy generation and cellular integrity. Warm cardioplegia with normothermic cardiopulmonary bypass cause three times more incidence of permanent neurologic deficits than the cold crystalloid cardioplegia with hypothermic cardiopulmonary bypass. Interruptions or inadequate distribution of warm cardioplegia may induce anaerobic metabolism and warm ischemic injury. To avoid these problems, tepid blood cardioplegia was recently introduced. MATERIAL AND METHOD: To evaluate whether continuous tepid blood cardioplegia is beneficial in clinical practice during valvular surgery, we studied two groups of patients matched by numbers and clinical characteristics. Warm group(37degree C) consisted of 18 patients who underwent valvular surgery with continuous warm blood cardioplegia. Tepid group(32degree C) consisted of 17 patients who underwent valvular surgery with continuous tepid blood cardioplegia. RESULT: Heartbeat in 100% of the patients receiving continuous warm blood cardioplegia and 88.2% of the patients receiving continuous tepid blood cardioplegia converted to normal sinus rhythm spontaneously after removal of the aortic cross clamp. There were no differences between these two groups in CPB time, ACC time, the amount of crystalloid cardioplegia used and peak level of potassium. During the operation, the total amount of urine output was more in the warm group than the tepid group(2372+/-243 ml versus 1535+/-130 ml, p<0.01). There were no differences between the two groups in troponin T level measured 1hr and 12hrs after the operation. CONCLUSION: Continuous tepid blood cardioplegia is as safe and effective as continuous warm blood cardioplegia undergoing cardiac valve surgery in myocardial protection.

Hypothermia is widely acknowledged as fundamental component of myocardial protection during cardiac operations. Although it prolongs the period of ischemic arrest by reducing oxygen demands, hypothermia is associated with a number of major disadvantages, including its detrimental effects on enzymatic function, energy generation, and cellular integrity. The ideal way to rotect the heart is to electromechanically arrest it and perfus it with blood that is aerobic arrest. However alternative technique has been developed, based on the principles of electromechanical arrest and normothermic aerobic perfusion using continuous warm blood cardioplegia. To determine if continuous warm blood cardioplegia was beneficial in clinical practice during valvular surgery, we studied two groups of patients matched by numbers and clinical characteristics. Group included is 31 patients undergoing valvular surgery who received intermittent cold crystalloid cardioplegia. Group II included 30 patients undergoing valvular surgery who received continuous warm blood cardioplegia. Our results suggest that the heartbeat in 100% of patients treated with continuous warm blood cardioplegia converted to normal sinus rhythm spontaneously after the removal of the aortic cross-clamp, compared to only 31% of the cold cardioplegia group. After operation, pericardial closure rate was 90% area in the warm group, compared to 35% area in the cold group. 12 hours after the operation, the total amount of urine output in the warm group was greater than that in the cold group (2863+/-127 ml versus 2257+/-127 ml; p<0.05). After the operation, left diaphragmatic elevation developed in 55% of the cold group but in 0% of the warm group. CK-MB level in the warm group was significantly lower than cold group (2.28+/-0.62 versus 9.96+/-2.12; p<0.01) 1 hour after operation and CK-MB level in the warm group was significantly lower than cold group (1.80+/-1.01 versus 6.00+/-1.74; p<0.05) 12hours after operation. Continuous warm blood cardioplegia is at least as safe and effective as hypothermic technique in patients undergoing cardiac valvular surgery. Conceptually, this represents a new approach to the problem of maintaining myocardial preservation during cardiac operations.

Teratoma of the testis is a type of mixed tumor made up of various kinds of tissue representing the three primitive layers of blastoderm. Recently we experienced two cases of testicular teratoma in 23-year-old male patients, so we report these two cases of testicular teratoma with review of literatures.
