PURPOSE: Tc-99m-tetrofosmin(TF) is a recently proposed myocardial imaging agent which has similar biokinetic characteristics to Tc-99m-sestamibi(MIBI). The aim of this study was to compare TF and MIBI myocardial perfusion SPECTs in detecting coronary artery disease. MATERIALS AND METHODS: One hundred and sixty patients(l0l males, 59 females, mean age 57+/-9 yr) who had undergone both myocardial perfusion SPECT (M- SPECT) and coronary angiography within 1 month were studied. M-SPECT was performed using TF in 115 patients and MIBI in 45 patients. Stress-rest one day protocol was used in all patients A coronary stenosis was considered significant when the luminal diameter > or =50% was compromised. The chi square test was used to compare, differences in sensitivity and specificity between the two groups. RESULTS: There was no difference in age and diseased coronary artery branches between the two groups. There were more male patients in TF group: Male-to-female ratios of TF and MIBI groups were 78:37 and 23:22, respectively (p<0.05). The overall sensitivity of TF study was 92% and specificity 36%. The overall, sensitivity and specificity of MIBI study were 93% and 30% respectively. There was no difference between TF and MIBI groups in identifying individual diseased coronary artery branches. CONCLUSION: One day stress-rest myocardial SPECT using either TF or MIBI was comparable and was a very sensitive test in detecting coronary artery disease.

Otocephaly is a rare malformations comprising hypoplasia or absence of the mandible (agnathia), ventromedial displacement and often fusion of external ears (synotia or otocephaly), and hypoplasia of the oral cavity (microstomia) and tongue (hypoglassia). This developmental complex represents a malformation of the first and second branchial arches and occurs sometimes with holoprosencephaly. We present the ultrasound detection of otocephaly and holoprosencephaly with cyclopia in a fetus of 27 gestational weeks 6 days. The use of three-dimensional (3-D) ultrasound made additional diagnostic ultrasound tomograms possible, and the volume reconstructions improved the imaging and the understanding of the condition.

Acute interstitial pneumonia is a fulminant disease of unknown etiology that usually occurs in a previously healthy person and produces the histologic findings of the organizing phase of diffuse alveolar damage. We experienced an autopsy case of acute interstitial pneumonia of unknown etiology. The patient was a 48 year old man who had been healthy and had not been exposed to organic dusts or other toxic materials. The chief complaints represented were dyspnea and a dry cough for several weeks before hospitalization, and the chest radiographs showed bilateral interstitial infiltrates. Patchy consolidation of air space was also identified and ground-glass attenuation similar to those described in ARDS was detected on high-resolution computed tomography. Steroid pulse therapy, mechanical ventilation, and antibiotics for superimposed bacterial infection were performed, but the symptoms did not improve and the patient died of generalized respiratory insufficiency and severe hypoxemia 2 1/2 months after hospitalization. At autopsy the macroscopic and microscopic findings were confined mainly to the lungs. On the whole, both lungs were firm in consistency and the external surface showed a cobblestone appearance. The cut surface showed almost complete replacement of the normal lung parenchyma with gray to yellow fibrous tissue with a little residual functional area remaining. The pathology of both open lung biopsy and autopsy tissue showed marked hyperplasia of type II pneumocytes, hyaline membrane formation, thickening of the alveolar wall due to extensive fibroblast proliferation, and relatively abundant young collagen deposition in the interstitium. An immunohistochemical stain for cytokeratin revealed epithelial hyperplasia and showed that the alveolar spaces were markedly shrunken by fibrous tissue.

Acute generalized exanthematous pustulosis (AGEP) is characterized by acute nonfollicular sterile pustules on a background of edematous erythema. Hydroxychloroquine (HCQ), an antimalarial drug, widely used to treat rheumatic and dermatologic diseases. HCQ has been reported to be an uncommon cause of AGEP. We report a 60-year-old woman with rheumatoid arthritis requiring the use of HCQ presented fever and erythematous eruption on the trunk with sterile pustules. Leukocytosis and elevated erythrocyte sedimention rate noted on laboratory examination. On the histopathological examination of the skin biopsy specimen showed neutrophilic infiltration and scattered eosinohpils. The lesions were resolved with removal of HCQ. The clinical course was consistent with the diagnosis of AGEP associated with HCQ. We reported a case of typical AGEP associated with HCQ in a patient with Rheumatoid arthritis. The patient presented resolution from cutaneous lesions with withdrawal of culprit drug, without the need of systemic steroid.

PURPOSE: Spinal cord injuries can lead to varying degrees and patterns of neurologic deficits, which depend on the level of the injury, duration, completeness. So we analyzed the relationship between the types of neurogenic bladder and the level of injury in the spinal cord injury. MATERIALS AND METHODS: From June 1997 to August 2002, one-hundred twenty seven spinal cord injury patients were studied by neurological and urological examination and video-urodynamic evaluation. The neurogenic bladder in spinal cord injury were analyzed into five types according to the injured level. RESULTS: The 94 males and 33 females had a mean age of 45.7+/-15.1 years (range 15 to 92). Mean follow up interval after injury was 33.9+/-48.4 months. Injured level was classified into five levels; cervical, thoracic, lumbar, and sacral. Of the 127 patients 37 (29.1%) was cervical, 18 (14.2%) was thoracic, 33 (26.0%) was lumbar, and 39 (30.7%) was sacral. When all patients were divided suprasacral and infrasacral lesion. Typically, suprasacral lesions show detrusor hyperreflexia, and infrasacral lesions have detrusor areflexia. 30 (37.5%) of 88 suprasacral lesions and 12 (30.8%) of 39 infrasacral lesions were presented to atypical. 35.7% of patients have combine spinal lesion, but 47.6% of patients have no causes for atypical patterns. 3 (27.3%) of 11 patients were followed up, they changed neurogenic pattern. CONCLUSIONS: In our results, video urodynamic findings showed that about 30 percent patients had atypical patterns of neurogenic bladder, and they have underlying disease about 52.4%. And 27% of followed patients changed neurogenic pattern of bladder. So, urodynamic study have an important role in the spinal cord injury for diagnosis of neurogenic pattern and selection proper treatment, catching out the interval change and correction of treatment method, and evaluation of prognosis.

Objective:
The aim of this study was to investigate postoperative imaging findings of patients who underwent breastconserving surgery for cancer and reconstruction with MegaDerm® (sheet-type and pellet-type), analyzing false positives and recurrences, using multi-modality images.
Materials and Methods:
This study included 201 women (age range: 28–81 years, mean age ± standard deviation: 53.2 ± 8.6 years) who underwent breast-conserving surgery and immediate reconstruction with MegaDerm®. Post-surgery, each patient underwent at least one mammography (MG), ultrasonography (US), and MRI, totaling 713 MG, 1063 US, and 607 MRI examinations. Postoperative images were reviewed separately for the two types of MegaDerm®, and suspicious imaging findings (false positives and recurrences) were analyzed, with a particular focus on the findings in direct contact with MegaDerm®.
Results:
MegaDerm® appeared as a circumscribed mass with homogeneous iso- or high density on MG, posterior shadowing on US, and no enhancement on MRI. Calcification was more common and increased in size in sheet-type MegaDerm®, while pellet-type often exhibited irregular margins. Nine out of 17 false positives had suspicious findings in direct contact with MegaDerm®, and six out of nine recurrences showed similar findings. Common suspicious findings included calcifications, asymmetries, and MegaDerm® irregularities on MG; masses and MegaDerm® irregularities on US; and enhancing masses and MegaDerm® irregularities with enhancement on MRI. Notably, MegaDerm® irregularity with calcification was observed on MG and US in only one recurrence case. In 44.4% (4/9) of false-positives in direct contact with MegaDerm®, suspicious findings showed no change or resolution on follow-up.
Conclusion
Suspicious imaging findings in direct contact with MegaDerm® may be associated with false positives or recurrences. Therefore, it is essential to recognize these characteristic findings and review the patient’s history of MegaDerm® insertion when in doubt.
