PURPOSE: Lymphoma originated from MALT is common in stomach but infrequently found in bronchus, salivary gland, thyroid gland and orbit. We report a case of multifocal MALToma in bilateral main lacriamal gland, hard palate without systemic metastasis. METHODS: A 45-year-old male without known systemic disease visited with movable mass in left upper eyelid for 5 months. RESULTS: We found the mass which was hot uptaked by whole body SPECT in left main lacrimal gland and hard palate. By excisional biopsy, the mass was diagnosed as MALToma. After 1 year it recurred in contralateral main lacrimal gland. It was diagnosed as the same MALToma by excisional biopsy. Relapse and other metastasis have not been observed yet up to now(November, 2002) , since we treated radiation therapy.

PURPOSE: To investigate the results of Advanced Surface Ablation (ASA) coupled with "smoothing" to smooth the ablation surface after covering masking fluid. METHODS: ASA was performed in 61 eyes with ablation depth of more than 75 microm. The mean refractive error was -5.88 +/- 1.27 D and mean ablation depth was 102.93 +/- 12.06 microm. Smoothing was performed in all patients (mean depth 16.79 +/- 2.43 microm, mean diameter 8.77 +/- 0.16 mm). Customized Aspheric Transition zone (CATz) was used in the laser algorithm. RESULTS: The mean refractive error was -0.29 +/- 0.41 D at postoperative 6 months and 97% of patients had an UCVA of 1.0 or better at postoperative 6 months. There was no statistically significant difference in magnitude of high-order aberrations at postoperative 6 months. The magnitude of total spherical aberrations increase was 0.084 microm at postoperative 6 months (p<0.05, paired t-test). The cornea was maintained clear in the majority of eyes. CONCLUSIONS: Excellent results were obtained by ASA coupled with "smoothing" in high myopia patients with an ablation depth greater than 75 microm.

Skip lesion is not uncommon feature in osteosarcoma and considered to be importantly associated with poor prognosis factor, and thus, should be excised with the main mass. The accurate pre-operative evaluation of the intramedullary extent of osteosarcoma is essential, because it determines the level of bone resection. Among the reliable detection methods, bone scan has a drawback of high rate of false negative results and regional MRI has a difficulty to cover the whole involved lesions without clinical suspicion. The authors report a case of osteosarcoma of the distal femur with a proximal skip lesion that was not detected by either regional MR imaging or by bone scan, but which was visualized by FDG-PET/CT.

Verrucous hemangioma is a variant of a capillary, cavernous, or mixed hemangioma which undergoes a reactive proliferative epidermal change. Most verrucous hemangiomas appear on the lower extremities, and most are present at birth or appear during childhood. We observed two patients who showed typical clinical and histopathological findings of verrucous hemangioma. Treatment was done by wide surgical excision and skin graft. The first rnale patient had a good therapeutic result but the second female patient had a recurrence at one month post-operative.

Numerous hypotheses have been put forth over the years to explain the development of bipolar disorder. Of these, circadian rhythm hypotheses have gained much importance of late. While the hypothalamus-pituitary-adrenal (HPA) axis hyperactivation hypothesis and the monoamine hypothesis somewhat explain the pathogenic mechanism of depression, they do not provide an explanation for the development of mania/hypomania. Interestingly, all patients with bipolar disorder display significant disruption of circadian rhythms and sleep/wake cycles throughout their mood cycles. Indeed, mice carrying the Clock gene mutation exhibit an overall behavioral profile that is similar to human mania, including hyperactivity, decreased sleep, lowered depression-like behavior, and lower anxiety. It was recently reported that monoamine signaling is in fact regulated by the circadian system. Thus, circadian rhythm instability, imposed on the dysregulation of HPA axis and monoamine system, may in turn increase individual susceptibility for switching from depression to mania/hypomania. In addition to addressing the pathophysiologic mechanism underlying the manic switch, circadian rhythm hypotheses can explain other bipolar disorder-related phenomena such as treatment resistant depression and mixed features.

Renal angiomyolipoma is composed of mature fats, smooth muscles and abnormal blood vessels which arises mainly from renal parenchyme and compresses the calyx or protrudes the renal cortex, but which extends into the renal cyst is rare. Recently it can be easily diagnosed preoperatively by several diagnostic modalities such as ultrasonography, computed tomography and several clinical signs associated with tuberous sclerosis, although it`s clinical and radiological features are similar with renal cell carcinoma. We report a case of renal angiomyolipoma without tuberous sclerosis, extending into the renalcyst, which was confused with renal pelvis tumor in a 73 years old male.

Neurilemmoma is well-encapsulated tumor of Schwann cell origin. The majority arise in peripheral nerve or cranial nerve, and rare in retroperitoneum. Although it is incidentally detected by the advances in diagnostic procedures, especially in ultrasound and computed tomography, it is confirmed by pathologic findings. The treatment is surgical excision. We report a case of retroperitoneal neurilemmoma arising from adjacent to adrenal gland, in 45 years old female.

Pregnancy induced hypertension is multifaceted syndrome with variable involvement of several key organ systems, so sensitive and specific laboratory tests for predicting severity and prognosis. and early diagnosis of this disease are required. Because heme catabolism results in equimolar production of carboxyhemoglobin, iron and bilirubin, a concomittant rise of these parameters would provide confirmation of increased heme catabolism. Microangiopathic hemolytic anemia may occurs in severe preeclampsia, but it is not known whether increased red cell turnover - occurs with mild preeclampsia as complication. The purpose of this study was to confirm that increased heme catabolism also occurs in patients with mild preeclampsia. The analysis of data was done on 23 cases with mild preeclampsia and 35 normal pregnant women, who were admitted to Yeungnam University Hospital from October 1992 to March 1993. The results were as follows. 1. The mean antepartum serum iron concentration was significantly higher in the group with mild preeclampsia (86.5+/-6.1 microg/dl) than in the controls (53.2+/-5.3 microg/dl). 2. The mean antepartum and postpartum carboxyhemoglobin concentrations were significantly higher in the group with mild preeclampsia (antepartum : 2.55+/-0.42 mg/dl, postpartum 1.21+/-0.4 mg/dl) than the controls (antepartum : 0.61+/-0.2 mg/dl, postpartum 0.53+/-0.2 mg/dl) 3. During postpartum, carboxyhemoglobin concentration in preeclampsia reduced significantly from antepartum level, but there was no difference between antepartum and postpartum carboxyhemoglobin concentrations among controls. 4. Bilirubin concentrations were similiar in both groups
