To evaluate the expressions of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) in thyroid neoplasms in a Korean population, we studied a total of 154 cases: papillary carcinoma of classical type (PTC), 86; follicular adenoma (FA), 21; follicular carcinoma (FC), 35; medullary carcinoma (MC), 3; undifferentiated carcinoma (UC), 5; and Hurthle cell neoplasm (HN), 4. Using immunohistochemical staining, COX-2 expression was detected in 62 (72.1%) PTC specimens, 5 (23.8%) FA specimens, 10 (28.6%) FC specimens, 0 (0.0%) MC specimens, 1 (20.0%) UC specimen, and 3 (75%) HN specimens. iNOS expression was detected in 66 (76.7%) PTC specimens, 4 (19.0%) FA specimens, 13 (37.1%) FC specimens, 0 (0.0%) MC specimens, 3 (60.0%) UC specimens, and 4 (100%) HN specimens. The results showed that COX-2 and iNOS were frequently expressed in the PTC and HN specimens, and iNOS was more frequently overexpressed in the FC specimens than in the FA specimens. In PTC, COX-2 and iNOS were significantly overexpressed in patients over 45 yr of age (p=0.029, p=0.041), and iNOS expression was increased in patients with a large primary tumor (p=0.028). These results suggest that the upregulation of COX-2 and iNOS may contribute to the tumor progression of thyroid gland, particularly in PTC and HN, and iNOS may play an adjuvant role during the tumor progression of FC.

The eye tumors are divided into intraocular and extraocular, and mainly involve lids, conjunctiva, cornea, and orbit. The authors analysed histopathological and clinical review of 9 cases of eye tumors that had experienced.

BACKGROUND: Mature cystic teratoma is a common type of ovarian tumor. Although squamous cell carcinoma (SCC) is the most common carcinoma in malignant transformations of ovarian mature cystic teratomas, SCC arising in a mature teratoma is rare. METHODS: This paper reports four cases of invasive SCC, a case of an adenosquamous cell carcinoma and a case of a pure in situ SCC arising in a mature cystic teratoma including a clinicopathological evaluation and an immunohistochemical study of the p53 protein and p21WAF1/CIP1. RESULTS: The mean age of the patients was 60 years. The sizes of the mature cystic teratomas in all cases were greater than 7.5 cm in the largest diameter. Five cases showed the nuclear accumulation of the p53 protein with no p21WAF1/CIP1 immunoreactivity. The other case showed the nuclear accumulation of p21WAF1/CIP1 without p53 expression. There was a significant inverse relationship between the p53 protein level and p21WAF1/CIP1 expression. CONCLUSION: A clinicopathological evaluation showed that a SCC arising from a mature cystic teratoma must be included in a differential diagnosis when the patient is over 42 years of age and the size of a mature cystic teratoma is greater than 75 mm in the largest diameter. It is suggested that p53 overexpression is implicated in the malignant transformation, and the p21WAF1/CIP1 expression level is dependent on alterations in the level of the p53 protein in these tumors.

Tsutsugamushi disease is an acute febrile illness caused by Orientia tsutsugamushi. It is characterized by fever, myalgia, lymphadenopathy, and rash. And it can be easily diagnosed by characteristic eschar and serologic testing. Nearly all of the patients with tsutsugamushi disease improve with antibiotics such as doxycycline. However, the fatality rate of untreated cases is seven to ten percent. The well-known causes of mortality are respiratory failure associated with pulmonary edema or adult respiratory distress syndrome. We report a case of tsutsugamushi disease complicated with acute respiratory distress syndrome and disseminated intravascular coagulopathy, despite of doxycycline treatment. A 78-year old woman was admitted to the hospital because of fever. Twelve days before admission she had suffered myalgia and some days later she developed a rash. Despite of management at a local clinic, her condition deteriorated and she was transferred to our hospital. On admission she presented with altered consciousness and two eschars on her right arm and right thigh. Under the initial diagnosis of scrub typhus, doxycycline was administered. Her fever subsided with the initiation of doxycycline. However, her hypoxia worsened progressively and she died on the fifth hospital day.

Patau syndrome is trisomy 13, one of the most common autosomal aberration associated with multiple congenital anomalies. Because trisomy 13 is generally associated with severe congenital anomalies and postpartum poor prognosis, antenatal diagnosis through antenatal ultra-sonogram and triple screening marker is very important. We present one case of trisomy 13 with abnormal ultrasound finding, holoprosencephaly, microcephaly, cleft lip and palate. And confirmed chromosomally with pregnancy termination.

PURPOSE: Occult intertrochanteric fractures are misdiagnosed as isolated greater trochanteric fractures in some cases. We investigated the utility of three-dimensional computed tomography (3D-CT) and magnetic resonance imaging (MRI) in the diagnosis and outcome management of occult intertrochanteric fractures. MATERIALS AND METHODS: This study involved 23 cases of greater trochanteric fractures as diagnosed using plain radiographs from January 2004 to July 2013. Until January 2008, 9 cases were examined with 3D-CT only, while 14 cases were screened with both 3D-CT and MRI scans. We analyzed diagnostic accuracy and treatment results following 3D-CT and MRI scanning. RESULTS: Nine cases that underwent 3D-CT only were diagnosed with isolated greater trochanteric fractures without occult intertrochanteric fractures. Of these, a patient with displacement received surgical treatment. Of the 14 patients screened using both CT and MRI, 13 were diagnosed with occult intertrochanteric fractures. Of these, 11 were treated with surgical intervention and 2 with conservative management. CONCLUSION: Three-dimensional CT has very low diagnostic accuracy in diagnosing occult intertrochanteric fractures. For this reason, MRI is recommended to confirm a suspected occult intertrochanteric fracture and to determine the most appropriate mode of treatment.

Congenital myotonic dystrophy is an autosomal dominantly inherited myotonic dystrophy, rare form, with an incidence estimated to be 13/100,000 liveborns. Affected newborns can present with intrauterine growth retardation, prematurity, birth asphyxia, respiratory distress, and always exhibit generalized muscular hypotonia. Feeding problems are common and an association with protein losing enteropathy, hydrops fetalis, and persistent pulmonary hypertension of the newborn has been described. Twenty-five percent of the affected infants die within the first 18 months of life. The molecular basis is an unstable DNA fragment consisting of a variable expansion of a CTG triplet, Dystrophia myotonica-protein kinase (DMPK) which is localized on chromosome 19q 13.3. The severity of the disease is directly correlated to the length of the CTG sequence. Women with idiopathic polyhydroamnios, decreased fetal movement, prematurity, hypotonia, should be counselled family, and mother, father and baby should be evaluated congenital myotonic dystrophy, as PCR (polymerase chain reaction). It is possible to diagnose congenital myotonic dystrophy, by PCR, antenatal test, such as CVS, amniocentensis. We experienced a case of recurrent congenital myotonic dystrophy, with neonatal death, twice, and report with a review of related literatures.

Patients with cardiac rupture due to blunt trauma have more than 50% mortality rate and most of them expire before they arrive at the hospital emergency room. Since patients typically present with cardiac tamponade, the diagnosis can be easily confirmed with physical examination, echocardiography, and chest CT scan. However, in our case of the massive hemothorax on right side without evidence of cardiac tamponade, the diagnosis for cardiac rupture does not seems to be easy. Therefore, we must assume the probability of cardiac rupture if we plan an explo-thoracotomy in a patients with massive right hemothorax without rib fracture. We describe two cases of cardiac rupture combined with pericardial laceration and right massive hemothorax by blunt chest trauma. The ruptured hearts of the patients were successfully closed using cardio-pulmonary bypass or cell saver system without detrimental sequelae.
