Mammography is the only examination capable of depicting malignant calcifications in breast. In some instances calcifications evident in mammogram and specimen mammograms are not observed in the histologic specimen. Therefore, wer retrospectively analyzed 27 cases in which hook-guided wire localization and biopsy had been performed to determine if microcalcifications were lost during histopathologic processing. Calcium was apparently lost during preparation of the block in about 7% of the cases and after slide preparation in about 11%, for a total possible loss of 18%. The authors recommend a protocol for avoiding these loss that involves performance of a more comprehensive examination of histologic sections by the pathologist and radiographic reexamination of paraffin-embedded tissue blocks with subsequent step sectioning by the pathologist.

We report a case of multiple myeloma with gastric involvement occurring in a patient who underwent an upper gastrointestinal series (UGIS), CT and MRI. UGIS depicted a luminal protruding mass, while contrast-enhanced CT demonstrated marked thickening of the gastric wall, with subtle contrast enhancement. At T1- and T2-weighted MR imaging, the mass showed iso- and intermediate signal intensity, respectively. After the administration of contrast material, subtle homogeneous enhancement was apparent.

This meta-analysis examined the surgical management of older patients (>80 years) with gastric cancer, who were often excluded from randomized controlled trials. We analyzed 23 retrospective cohort studies involving 18,372 patients and found that older patients had a higher in-hospital mortality rate (relative risk [RR], 3.23; 95% confidence interval [CI], 1.46–7.17; P<0.01) and more post-operative complications (RR, 1.36; 95% CI, 1.19–1.56;P<0.01) than did younger patients. However, the surgical complications were similar between the two groups. Older patients were more likely to undergo less extensive lymph node dissection and longer hospital stays. Although older patients had statistically significant post-operative medical complications, they were not deprived of surgery for gastric cancer.The comorbidities and potential risks of post-operative complications should be carefully evaluated in older patients, highlighting the importance of careful patient selection. Overall, this meta-analysis provides recommendations for the surgical management of older patients with gastric cancer. Careful patient selection and evaluation of comorbidities should be performed to minimize the risk of post-operative complications in older patients, while recognizing that they should not be deprived of surgery for gastric cancer.

PURPOSE: To verify the effect of preservative-free Dorzolamide/Timolol fixed combination (PFDTC) on intraocular pressure (IOP) elevation after vitrectomy. METHODS: We retrospectively reviewed medical records of 33 patients who used PFDTC after pars plana vitrectomy. All patients' visual acuity and IOP was measured and symptoms of conjunctival irritation were investigated through survey and slit lamp examination. RESULTS: Before vitrectomy, the mean IOP was 13.6 ± 4.4 mm Hg which was elevated to 31.7 ± 5.4 mm Hg after vitrectomy (p < 0.001) and applying eyedrop lowered the mean IOP to 17.2 ± 7.0 mm Hg (p < 0.001). Regardless of tamponade material type, all elevated IOP decreased (p < 0.001) and the IOP of all 33 eyes did not rise to over 30 mm Hg again. No additional surgery for IOP control was needed during two-month follow-up period. Of the 33 patients using PFDTC, patients who felt discomfort were five (15.2%) and no patients showed side effects severe enough to stop use of eyedrop. CONCLUSIONS: PFDTC is an anti-glaucomatic agent which can reduce the IOP by inhibiting aqueous humor production. Without need for additional surgery, the eyedrop can effectively lower elevated post-vitrectomy IOP, with expectation of good patient compliance due to low risk of conjunctival irritation.

A biliary cystadenoma (BC) and a cystadenocarcinoma (BCA) are rare neoplasms of the liver. Among 178 patients with primary liver neoplasms who underwent surgery during the last two years at our department, there were only one case of BC and three cases of BCA. The BC case was a 57-year-old female with 15-cm-sized multilocular cystic mass containing mucin. That patient, who had undergone a simple excision of a liver cyst 6 years earlier under the diagnosis of a cystadenoma, received a repeated wedge resection and is still doing well, no recurrence, 41 months after the resection. One BCA case was a 59-year-old female with an 8-cm-sized multilocular cystic mass. She underwent an extended left lobectomy and is still alive, without recurrence, 55 months later. Another BCA case was 77-year-old female with multiple multilocular masses which had degenerated due to sclerotherapy; the masses were removed by a wedge resection. She has been alive 35 months without recurrence. The other BCA case was a 37-year-old female with a 10-cm-sized unilocular mass with lung metastasis. She underwent an extended left lobectomy and survived 22 months. Malignant transformation of a BC to a BCA is well documented, and recurrence is the rule following incomplete resection. Complete resection of a BC and radical resection of a BCA seem to offer a chance for long-term survival.

The purpose of this study is to observe and compare the remineralization tendencies of artificially demineralized enamel by remineralization solutions of different degree of saturations at pH 5.5, using a polarizing microscope and computer programs (Photoshop, Image pro plus, Scion Image, Excel). For this study, 36 sound permanent teeth with no signs of demineralization, cracks, or dental restorations were used. The specimens were immersed in lactic acid demineralization solution for 3 days in order to produce dental caries artificially that consist of surface and subsurface lesions. Each of 9 or 10 specimens was immersed in pH 5.5 lactic acid buffered remineralization solution of three different degrees of saturation (0.25, 0.30, 0.35) for 12 days. After the demineralization and remineralization, images were taken by a polarizing microscope (x 100). The results were obtained by observing images of the specimens, and using computer programs, the density of caries lesions were determined. In conclusion, in the group with the lowest degree of saturation, remineralization occurred thoroughly from the surface to the subsurface lesion, whereas in the groups with greater degree of saturation showed no significant change in the subsurface lesion, although there was corresponding increase in the remineralization width on the surface zones.

PURPOSE: Several studies have used FISH (fluorescence in situ hybridization) to analyze aneuploids in various solid tumors. FISH, using chromosome-specific, alpha-stellite DNA probes, can be used to detect aneusomy in interphase and/or metaphase cells. The aims of this study were to compare the FISH cen tromere signals from benign breast tumors and to those from breast cancers and to evaluate the clinico pathologic parameters and the aneusomic patterns involving chromosomes 1, 11, and 17 in breast cancers. METHODS: FISH was performed on touch preparations from 15 benign breast-tumor and 29 breast-cancer specimens. The frequency of aneusomy, measured by nondisomy, was determined for chromosomes 1, 11, and 17 through the use of chromosome-specific alpha-stellite DNA probes. The frequency of chromosome- specific aneusomy was then correlated with clinicopathologic parameters, including tumor size, lymph- node involvement, estrogen receptor, and nuclear grade. RESULTS: Only one of the 15 benign breast tumors was shown to be aneusomic for chromosome 1. The other 14 cases of the benign breast tumors showed no evidence of aneusomy for any of the 3 chromosomes. In breast cancers, however, 26 of the 29 cases (90%) were exhibited aneusomy of at least 1 of the 3 chromosomes evaluated and chromosome 1 was most frequently aneusomic (26 of 29 cases (90%)). The present study also suggested a possible correlation between the numeric abnormality of chromosome 1 and estrogen receptor levels. No significant correlations with tumor size, regional lymph-node metastasis, and nuclear grade were observed. CONCLUSION: These findings suggest that chromosome-specific aneusomy is more frequently observed in breast cancers than in benign breast tumors and that aneusomy of chromosome 1 correlates with estrogen receptor levels.

BACKGROUND: Now, breast reconstruction is being performed in many cases after mastectomy by using tissue expander or TRAM flap. But conventional mastectomy leaves a long linear scar tissue which is also seen on the breast skin after breast reconstruction. Skin spring mastectomy with immediate reconstruction leaves a minimal scar tissue, even though, with circumareolar incision, it makes no visible scar tissue. PURPOSE: The purpose of this study is 1) to identify the clinical indications for Skin-spring mastectomy (SSM) with immediate reconstruction, 2) to evaluate the clinical results and 3) to encourage the application of this method. MATERIALS AND METHODS: During recent 20 months, breast cancer surgery were 467 cases, mastectomy were 368 (78.8%, 368/467), mastectomy with breast reconstruction were 30 case (8.2%, 30/368), Among 30 reconstruction cases, Skin-spring mastectomy (SSM) with circumareolar incision and immediate reconstruction were performed in 9 patient. Our patient selection criteria was as follows; 1) patient's desire of reconstruction on cosmetic aspect 2) clinically early breast cancer 3) moderate breast size 4) central locating tumor 5) no Skin involvement. RESULTS: 1) we performed 9 cases of Skin-spring mastectomy (SSM) with circumareolar incision and immediate reconstruction. 2) Three patient who complainted palpable mass were diagnosed by FNA for breast cancer and the other 6 patient were proved by ductal biopsy in 4 cases whose complaint was bloody nipple discharge, a H-wire biopsy in whose mammography revealed multiple microcalcifications and a punch biopsy in whose nipple was eczematous. All cases were suspected for early breast cancer preoperatively. 3) Four cases were stage 0, 3 cases were stage I lesions and 2 cases were stage III in postoperative pathologic staging. 4) All the patients were satisfied with their cosmetic results. CONCLUSIONS: Skin-spring mastectomy (SSM) with immediate reconstruction is new method for breast cancer operation with modified skin incision and shows good aesthetic results. we propose more frequent application of this method for indicated patient, but we need futher follow-up of local recurrence rate and detection rate in these patients.

It is essential to predict possibility of difficulties beforehand in ventilating or intubating the patient for the safe airway management and anesthetic maintenance. Even if there is no internal invasion, external compression of an enlarged neck mass can cause tracheal stenosis. The patient with nontoxic goitor had symptoms of dysphagia, exertional dyspnea and wheezing. There was difficulty in endotracheal passage of small bronchoscope through the compressed portion of the trachea during preoperative bronchoscopic examination. We premolded an armored endotracheal tube to fit the patient's trachea based on chest radiography, computed tomography and brochoscopic findings. Endotracheal intubation and thyroidectomy was successful and the patient discharged without any complication. We report a new method of intubation in patient with nontoxic goiter that obstructs the trachea by compression.
