A new and simple predictive formula for non-sentinel lymph node metastasis in breast cancer patients with positive sentinel lymph nodes, and validation of 3 different nomograms in Turkish breast cancer patients.

BACKGROUND: Nomogram accuracies for predicting non-sentinel lymph node (SLN) involvement vary between different patient populations. Our aim is to put these nomograms to test on our patient population and determine our individual predictive parameters affecting SLN and non-SLN involvement. PATIENTS AND METHODS: Data from 932 patients was analyzed. Nomogram values were calculated for each patient utilizing MSKCC, Tenon, and MHDF models. Moreover, using our own patient- and tumor-depended parameters, we established a unique predictivity formula for SLN and non-SLN involvement. RESULTS: The calculated area under the curve (AUC) values for MSKCC, Tenon, and MHDF models were 0.727 (95% confidence interval (CI) 0.64-0.8), 0.665 (95% CI 0.59-0.73), and 0.696 (95% CI 0.59-0.79), respectively. Cerb-2 positivity (p = 0.004) and size of the metastasis in the lymph node (p = 0.006) were found to correlate with non-SLN involvement in our study group. The AUC value of the predictivity formula established using these parameters was 0.722 (95% CI 0.63-0.81). CONCLUSION: The most accurate nomogram for our patient group was the MSKCC nomogram. Our unique predictivity formula proved to be as equally effective and competent as the MSKCC nomogram. However, similar to other nomograms, our predictivity formula requires future validation studies.

Visceral leishmaniasis as a rare cause of granulomatosis hepatitis: a case report.

Visceral leishmaniasis (VL) is one of the parasitic infections causing different pathogeneses of various systems including intraabdominal solid organs. L. donovani and L.infantum, particularly in Turkey, have been diagnosed in systemic infections. In the present case study, a 43-year-old woman with left upper abdominal pain, persistent fever and splenic pathology according to the radiological findings was investigated. Laboratory findings showed elevated liver function tests and anemia while radiological studies revealed splenomegaly, and nodular infiltration and laceration of the spleen. Because of enlarged intraabdominal lymph nodes observed during surgery, a lymph node biopsy and a liver biopsy were also performed along with the splenectomy. Results from the pathological examination of the spleen were nonspecific and the liver biopsy confirmed a diagnosis of granulomatosis hepatitis. Further examination of the hepatic granulomatosis including parasitic evaluation and serological evaluation with the rK39 dipstick test revealed VL. In conclusion, in cases of visceral organ pathology accompanied by persistent fever, and hematological disorders, parasitic infections, particularly VL, should be considered in the differential diagnosis.

Variables affecting patient satisfaction in breast surgery: a cross-sectional sample of Turkish women with breast cancer.

OBJECTIVE: In Turkey, despite the fact that breast cancer accounts for 24.1% of all cancer in women, a very small number of these patients receive breast reconstruction. This low percentage would seem to indicate that there are several factors affecting the decision of which surgical procedure should be selected. The aim of this study was to establish the demographical, medical, and psychological factors associated with the breast cancer patient's decision-making process, and assess their satisfaction with the type of surgery received. METHOD: We assessed long-term satisfaction with the type of surgery received; satisfaction with the information process by which the surgery decision is taken; feelings of ambivalence or regret regarding the type of surgery received in both mastectomy (n = 50) and breast reconstruction patients (n = 25). Additionally, breast cancer survivors were compared with age-matched healthy control volunteers (n = 50) in terms of demographics, body image and self-esteem, which could be expected to affect their preferences. We administered a demographical and medical information form, Structured Clinical Interview for DSM-IV, Clinical Version (SCID-I), the Body Cathexis Scale (BCS); and the Rosenberg Self-Esteem Scale (RSE). RESULTS: In both groups, women with a low income and less education were more likely to experience decision regret or low satisfaction. Moreover, total mastectomy-alone patients had lower self-esteem compared to reconstructive surgery patients and healthy women. CONCLUSION: Early stage breast cancer is a chronic disease and patients have to live with the consequences of their decision for many years. At the same time, the type of surgery is decided on when patients are in an acute phase and under intense pressure. Therefore, the decision making process needs to be explored more, especially breast cancer patients with less education and low income need better assistance and more detailed explanation of their options.

Effect of weight loss on bone metabolism: comparison of vertical banded gastroplasty and medical intervention.

BACKGROUND: We studied the effects of weight loss on bone metabolism. METHODS: 16 consecutive surgically-treated (14 female, 2 male) morbidly obese patients and 65 obese (53 male, 12 female) medically-treated patients were enrolled in an observational study. Surgical treatment for morbidly obese patients was vertical banded gastroplasty (VBG). Studies were performed prior to and 12 months after the start of treatment. Bone mineral density (BMD), bone turnover markers, sex steroids, calcium excretion and parathyroid hormone measurements were done at each visit. RESULTS: Weight loss was more prominent with surgical than with medical treatments. Bone loss was also pronounced in the surgical treatment group, and occurred at the hip level only (P<0.05). Compared to previously reported studies, where the effects of malabsorptive treatments for obesity on bone metabolism were studied, calcium excretion and parathyroid hormone levels did not change after VBG or medical therapy. For both groups, bone markers indicated an increased bone turnover, evidenced by increased urinary excretion of deoxypyridinoline and serum levels of osteocalcin (P<0.05). Sex steroid measurements revealed a decrease in estradiol levels in the surgical treatment group, but not in medical treatment group. This finding was thought to be secondary to less weight loss in the medical group. CONCLUSION: Our data indicate that weight loss causes bone loss. The bone loss is independent of the method of weight reduction. However, the mechanism of the bone loss is not clear. It may be explained partly by reduced estradiol levels in female patients. Because the mechanisms of bone disease after weight loss remain unclear, it is difficult to determine the most effective treatment. It is important to detect osteopenia early, before fractures occur. Measuring BMD appears to be the only reliable method for screening.

Superior mesenteric artery aneurysm.

A 38-year old woman with mid-epigastric pain, diarrhea, and weight loss, underwent resection of a superior mesenteric artery aneurysm and primary repair of the artery. Pathological examination showed degenerative atherosclerotic changes, marked medial and intimal thickening, and vegetations. Microbiological studies demonstrated Streptococcus viridans as the infecting organism of this mycotic aneurysm. The patient made a good recovery and remained well after 3 years.
