Squamous cell carcinoma is a rare complication of chronic osteomyelitis. Squamous cell carcinoma of extremity campromises approximately 1 to 2% of all squamous cell carcinoma and of these 2.5 to 4.5% are secondary to chronic osteomyelitis. Biopsy of squamous cell carcinoma, which arises in the proliferating edge of the cutaneous ulcer and invades the bone, should include tissues from all portion of sites of ulcer including bone marrow spaces. But histological diagnosis may be difficult becasue of preexisiting and coexisisting metaplasia and pseudo-epitheliomatous hyperplasia. With prompt and aggressive surgical treatment, the prognosis for patient with squamous cell carcinoma secodary to chronic osteomyelitis is good. Routine regional lymphadenectomy at site of amputation seems unnecessary. This case report represets an unusual bone marrow involvement of squamous cell carcinoma which was complicated by femur fracture.

This study was conducted to examine the changes in the shape of the Sprague-Dawley rats' articular disk following postural hyperpropulsion by observing their articular specimens through light and electronic microscopes after following 2-week and 4-week postural hyperpropulsion from their four weeks of age. The findings of this study are summarized as follows, It was shown that as compared with the control group, the experimental group indicated a significant increase in thickness of the 2-week groups' anterior and postreior portion of the articular disc. The experimental group showed statistically more significant increase in thickness of the 4-week groups' anterior portion of the articular disc than the control group. Light micrograph showed that the experimental group had more fibroblast in the anterior portion of the 2-week and 4-week groups than the comparing group. The 2-week groups showed in the findings through the electronic microscope that there were found the well developed and dilated HER which seems to actively synthesize the extracellular matrix including collagen, the cells with the well developed RER without distention which seems to actively synthesize the intracellular microfilaments due to the well developed free ribosome, and the typical chondroid cells. In addition, there was more fibroblast cell with the distended and well developed RER in the anterior area of the experimental group than that of the control group. The 4 week experimental group's anterior area of the disk had more cells than that of the control group while fibroblast with the well developed RER and free ribosome was quite abundant. Based on the above result of this study, it was shown that the functional hyperpropulsion of the mandible causes the changes in the nature of the mechanical load to the certain portion of the articular disk. As a result, it seems that there may be occurred some changes in morphology of the disc by adaptation or confrontation with these changes at the cellular level.

Resveratrol has been reported to exert anticancer activity via modulation of multiple pathways and genes. In this study, we examined the effect of resveratrol on YD-10B human oral squamous cell carcinoma cells and its molecular mechanisms of action. We found that resveratrol inhibited the proliferation of YD-10B cells in a dose- and timedependent manner. The suppressive effect of resveratrol was accompanied by a reduction in Bmi-1 gene expression.We observed that silencing the Bmi-1 gene by small interfering RNA effectively downregulated the levels of GLUT1 mRNA and protein, which were also repressed by resveratrol. Bmi-1 silencing increased the number of YD-10B cells in S-phase arrest by approximately 2.3-fold compared with the control. In conclusion, the results of the present study demonstrate, for the first time, that resveratrol suppresses Bmi-1-mediated GLUT1 expression in human oral squamous cell carcinoma cells and suggest that the specific molecular targeting of Bmi-1 and/or GLUT1 expression can be combined with a chemotherapeutic strategy to improve the response of oral cancer cells to resveratrol.

Genetic imbalances are a major cause of congenital and developmental abnormalities. We report the first case of a 3p26 microdeletion and 5q35.2q35.3 microduplication in a newborn with multiple congenital anomalies evaluated using chromosomal microarray analysis (CMA) and fluorescence in situ hybridization (FISH). The patient was born at 30 weeks and 2 days of gestation with a body weight of 890 g. He had symmetric intrauterine growth restriction, microcephaly, facial dysmorphism (hypertelorism, blepharophimosis, mild low-set ears, high-arched palate, and micrognathia), and right thumb polydactyly. Echocardiography revealed an atrial septal defect and patent ductus arteriosus. Furthermore, CMA revealed a concurrent microdeletion in 3p26 and a microduplication in 5q35.2q35.3. FISH analysis showed that these genetic changes resulted from a translocation mutation between chromosomes 3 and 5. The patient’s mother had mild intellectual disability, short stature, and facial dysmorphism, while his father had a normal phenotype. However, parental FISH analysis revealed that the asymptomatic father carried a balanced translocation of chromosomes 3p26 and 5q35. CMA and FISH tests are useful for diagnosing neonates with multiple congenital abnormalities. Further parental genetic investigation and proper genetic counseling are necessary in cases of chromosomal abnormalities inherited from parental balanced translocations.

Xanthogranulomatous cholecystitis is an extremely rare benign inflammatory disease of the gall bladder characterized by yellowish focal nodular appearance with tissue necrosis and lipid-containing histiocyte (xanthomacell). Recently, we experienced a case of xanthogranulomatous cholecystitis. A 71-year old woman was admitted with the complaints of RUQ pain for 1 month. On abdominal ultrasound examination, there were diffuse gallbladder wall thickening, echogenic nodule with acoustic shadow, the calculous cholecystiti and the gall badder cancer were strongly suspected and the operation was performed. At operation the gall bladder was marked enlarged and wall thickening with two brownish, oval shaped, smooth surfaced stones. The specimen was revealed a xanthogranulomatous cholecystitis by the pathology.

A dedifferentiated liposarcoma of the retroperitoneum is an extremely rare tumor. A 51-year old man was admitted to our department because a retroperitoneal mass was seen on abdominal computed tomography at another hospital. Computed tomography of the abdomen and magnetic resonance imaging showed a large pelvic mass located in the right hemipelvis, and it was pushing the right ureter and invading the right kidney, duodenum, colon and inferior vena cava. The patient underwent right radical nephrectomy, pylorus preserving pancreatoduodenectomy, right hemicolectomy and artificial blood vessel replacement for the inferior vena cava. The histopathological diagnosis was dedifferentiated liposarcoma and the patient was free from recurrence on the computed tomography that was done 6 months after the operation.

We report here on a case of priapism that was associated with the use of tadalafil. A 41 year-old-man visited our urology outpatient department with a relapsed erection he'd experienced for 3 days. He had no contributing factors for the priapism. He had taken tadalafil, which was prescribed at a local medical center 3 days previously. After the development of priapism, he first visited the emergency department of other hospital. Aspiration was done and then the priapism was resolved. Yet the priapism recurred 2 days later, andaspiration and other bedside management failed to resolve it. After his arrival to our department, weimmediately performed a caverno-glandular shunt with 18-gauge needle and we observed bright reddish- color blood. An intracorporal ephedrine injection and saline irrigation were then done. After that, the patient gradually experienced detumescence. The priapism did not recur during the 2 days of the hospitalization period. At the outpatient follow-up of 3 months later, patient almost recovered to his full erectile function and he had normal sexual activity.
