Ovarian tumor in pregnancy is not rare and benign cystic teratoma is most common ovarian tumor in pregnancy. Most ovarian tumor in pregnancy is found at first and second trimester but sometimes found at third trimester and it is difficult to make a decision for management. Moreover physician should consider fetal age and mother's condition, and weigh outcome of operation for complicated ovarian tumor in pregnancy. Torsion of ovarian tumor is not an uncommon complication during first trimester of pregnancy and puerperium but rare occurs during the third trimester of pregnancy. We have experienced a case of torsion of benign cystic teratoma of ovary which occurred at 37 weeks gestation in a 25 year-old woman. So we report this case with a brief review of literature.

BACKGROUND: Methods to detect and quanitify Mycobacterium leprae(M. leprae)are needed for studies involving the epidemiology, pathogenesis, and chemotherapy of leprosy. Serological assays and skin tests lack the sensitivity and specificity to serve as diagnostic tool for M. leprae infection. The polymerase chain reaction(PCR) based on the selective amplification of an 530-bp frangment of the gene encoding the proline-rich antigen of M. leprae was performed with sections of fixed or frozen biopsy samples from leprosy patients. OBJECTIVE: This study was done to investigate the applicability of PCR for the detection of low numbers of M. leprae in tissues and peripheral blood. METHODS: The PCR was used to amplify a 530-base-pair M. leprae DNA with the thermoxtable Taq DNA polymerase. RESULTS: The In frozen skin tissues and peripheral blood of leprosy patients. relatively high detection rates of PCR products was achieved by using direct gel analysis as well as Southern blot hybridization. CONCLUSION: These results suggest that PCR amplification for the detection of M. leprae may be useful for the epidemiologic study of large papulations as well as coinical astudies on the individual patients.

Cutaneous and subcutaneous metastases from the neoplasm of visceral organs are uncommon and have been estimated to occur in only 0.7%∼9% of patients. Among these cases, breast cancer is the most frequently observed malignancy. The incidence of cutaneous metastasis of breast cancer is 23.9%. The most common clinical manifestation of cutaneous metastasis of breast cancer is non-fixed painless erythematous nodules on the anterior chest. However, cutaneous metastasis of breast cancer shows a wide range of clinical manifestations and can mimic benign dermatologic lesions such as erythema annulare centrifugum, contact dermatitis, cellulitis, and erysipelas. We report a 52-year-old woman who presented with diffuse purpuric macules and patches on the right trunk. Finally, based on the clinical and pathologic findings, a diagnosis of cutaneous metastasis of breast cancer was made, and the patient expired 1 year later.

BACKGROUND: Vascular lesions can be diagnosed by biopsy, simple x-ray, ultrasound, CT, MRI, venography and MR angiography. These diagnostic tools can identify the detailed structure and abnormalities in the peri-lesional area of vascular lesions. Color Doppler ultrasound (CDU) can demonstrate the hemodynamic features, distribution of veins and arteries, shunts and structures of vascular lesions. Authors have tried to categorize vascular lesions with CDU and also applied this to the selection of treatment methods. MATERIALS AND METHODS: Forty-seven vascular lesions were evaluated by means of CDU. All patients underwent a complete clinical evaluation as well as peak systolic velocity (PSV), peak diastolic velocity (PDV), resistive index (RI) of feeding arteries. In particular, we evaluated the hemodynamic features and structures of vascular lesions. We categorized the vascular lesions and then treated them with systemic steroid, compression, SPTL1 Dye laser, steroid intralesional injection and sclerotherapy. We evaluated the clinical improvement and objective effects of treatments by CDU. RESULTS: There were 37 hemangiomas and 10 vascular malformations. Vascular lesions were classified by the hemodynamic features and structures: category Ia (infantile hemangioma, regressed infantile hemangioma), Ib (RICH), Ic (deep hemangioma, mixed hemangioma), II (arteriovenous malformation), III (venous malformation, verrucous hemangioma). The clinical improvement after treatment was associated with the decrease of PSV and RI values. The clinical improvement above 50% resolution of the lesion showed 70.9% in category Ia, 50% in Ib, 66.6% in Ic, 83.3% in II and 50% in III. CONCLUSIONS: The analysis of hemodynamic feature and structures by CDU can be helpful in the study of vascular lesions. These processes suggest CDU be a useful modality in differential diagnosis of vascular lesions and a more advantageous tool in the decision of treatment policy than the conventional modalities. And it is also useful for the evaluation of treatment effects.

Background:
To date, the clinical significance of visually equivocal amyloid positron emission tomography (PET) has not been well established.
Objective:
We studied the clinical significance of equivocal amyloid PET images from the Alzheimer’s Disease Neuroimaging Initiative (ADNI).
Methods:
Subjects with F-18 florbetapir PET scans at baseline who were followed up for 4 years were selected. Clinical characteristics, imaging biomarkers, cognitive function, and rate of conversion to AD were compared in subjects with visually equivocal findings.
Results
Of 249 subjects who completed the follow-up, 153 (61.4%), 20 (8.0%), and 129 (30.5%) were F-18 florbetapir-negative, -equivocal, and -positive, respectively. The mean standardized uptake value ratios (SUVR) of F-18 florbetapir PET were 0.75 ± 0.04, 0.85 ± 0.10, and 1.00 ± 0.09 for each group (p <0.001 between groups), and 15.0%, 70.0%, and 98.7% of patients were quantitatively above the positive threshold. The change in the SUVR of F-18 florbetapir PET was higher in the equivocal (6.09 ± 3.61%, p <0.001) and positive (3.13 ± 4.38%, p <0.001) groups than the negative group (0.88 ± 4.28%). Among the subjects with normal or subjective memory impairment and mild cognitive impairment, 5.3% with negative amyloid PET and 37.5% with positive amyloid PET converted to AD over the 4-year period. None of the equivocal amyloid PET subjects converted to AD during this period.

Hypnic headache is a unique headache disorder that occurs exclusively during sleep and often with "alarm-clock" consistency. It is a rare, benign, moderately severe, enduring headache syndrome that occurs in middle-aged to elderly adults and affects both sexes. The pathophysiology of hypnic headache is unknown, but its circardian periodicity and responsiveness to lithium suggest chronobiologic sleep disturbance contributing to the genesis of hypnic headache. We have recently experienced 2 cases of hypnic headache. They showed the characteristic signs of hypnic headache. We present our cases and discuss the pathophysiology of hypnic headache.

Carcinoma of the fallopian tube accounts for less than 1% of all cancers of the female genital tract. The histology and behavior of fallopian tube cancer are simillar to ovarian cancer; thus evaluation and treatment are also essentially the same. Unlike ovarian cancer, fallopian tube cancer begins in a hollow viscus, and early lesions may be less likely to be associated with extensive intraperitoneal carcinoma. Two postmenopausal women presented with a pelvic mass. Pathologic examination of the resected specimens revealed primary adenocarcinoma of the fallopian tube. We have experienced two cases of fallopian tube cancer and reported with brief review of literature
