[An axillary metastasis as the first sign of the breast carcinoma--a case review].

BACKGROUND: Carcinoma of the breast is the most commonly diagnosed women cancer. Less than 1% of the patients diagnosed with breast cancer initially present with axillary metastases as their only clinical manifestation. CASUISTIC: We report case of 58 years old woman with occult breast carcinoma in which extensive axillary node metastasis was the first manifestation. DISCUSSION: Breast cancer presenting with axillary metastases and no clinical apparent primary tumour in the breast is an uncommon form of stage II or IV of this disease. Ultrasonography, mammography, MRI and excisional biopsy are indicated for detecting occult primary tumours. The appropriate treatment of the breast after an axillary presentation of occult breast carcinoma continues to be a controversial issue. Complete axillary lymph node dissection is indicated in all patients. As a local treatment of the breast is indicated irradiation of the breast or total mastectomy or subcutaneus mastectomy with application of the breast prothesis. CONCLUSION: Axillary metastasis is rare first sign of breast cancer. Diagnostics of the occult breast carcinoma is difficult. The treatment of occult breast carcinoma is still controversial.

[Our experience with the sentinel lymph node detection].

BACKGROUND: Axillary lymph node staging is the most powerful predictor of survival in breast cancer women. Sentinel lymph node biopsy (SLNB) is more accurate method in evaluation of axillary lymph node staging than complete axillary lymph node dissection (CALND) because of more precious histological and imunohistochemical assessment of the first draining lymph nodes. Furthermore, SLNB eliminates complications resulting from CALND. MATERIAL AND METHODS: SLNB is either performed using blue dye technique or using of combination of blue dye and radioguided technique. We prefer two days protocol in application of Tc 99 radiocolloid. There were used both techniques for detection sentinel lymph nodes and results were compared. RESULTS: There were performed 21 SLNBs using blue dye technique, Group A, and 20 SLNBs using combination of blue dye and radioguided technique, Group B, from October 2001 to November 2003. Sentinel lymph nodes were not detected in Group A in two cases, false negativity occurred two times in this group. Sentinel lymph nodes were detected in all cases in Group B and there was no false negativity present in this group. CONCLUSION: Combination of blue dye and radioguided technique is more precious in detection of sentinel lymph node than blue dye technique itself. Two days protocol of application of Tc 99 radiocolloid enables performing this method even in hospitals, where the Department of Nuclear Medicine is not available.

[When should surgery be performed in traumatic hemoperitoneum ].

Authors in their theoretical report discuss problems of traumatic haemoperitoneum resulting from blunt abdominal injury including diagnostics and therapy. They put the stress on diagnostic-therapeutic algorithm. It is emphasized the necessity of immediate US of the abdomen and at the haemodynamically stable patients helical CT scan. Classification of injured certain abdominal cavity organs is mention and suggested unification of these classifications. It is highlighted conservative treatment of traumatic haemoperitoneum with regular monitoring including monitoring of intralpha abdominal pressure and abdominal compartment syndrome. Damage Control Surgery System, as a new strategy, is discussed in a part regarding operative management.

Managing selenium-contaminated agricultural drainage water by the integrated on-farm drainage management system: role of selenium volatilization.

The Integrated on-Farm Drainage Management (IFDM) system was designed to dispose of selenium (Se)-contaminated agricultural irrigation drainage water through the sequential reuse of saline drainage water to grow crops having different salt tolerance. This study quantified the extent of biological volatilization in Se removal from the IFDM system located in the western San Joaquin Valley, California. Selenium volatilization from selected treatment areas, including pickleweed (Salicornia bigelovii Torr.), saltgrass (Distichlis spicata L.), bare soil, and the solar evaporator, was monitored biweekly using an open-flow sampling chamber system during the pickleweed growing season from February to September 1997, and monthly from September 1997 to January 1998. Biological volatilization from the pickleweed section removed 62.0 +/- 3.6 mg Se m(-2) y(-1) to the atmosphere, which was 5.5-fold greater than the Se accumulated in pickleweed tissues (i.e., phytoextraction). The total Se removed by volatilization from the bare soil, saltgrass, and the solar evaporator was 16.7 +/- 1.1, 4.8 +/- 0.3, and 4.3 +/- 0.9mg Se m(-2) y(-1), respectively. Selenium removal by volatilization accounted for 6.5% of the annual total Se input (957.7mg Sem(-2) y(-1)) in the pickleweed field, and about 1% of the total Se input (432.7 mg Se m(-2) y(-1)) in the solar evaporator. We concluded that Se volatilization under naturally occurring field conditions represented a relatively minor, but environmentally important pathway of Se removal from the IFDM system.

[Early breast carcinoma--diagnosis and therapy].

The authors are presenting a review of the current state of diagnosis and surgical treatment of the early breast cancer, an algorithm of the diagnosis and the treatment. The authors are showing the impact of the breast preserving surgery and from their point of view present experience with 362 patients operated at the General Surgery Pardubice assembled in years 1998 and 1999.
