Wernicke's Encephalopathy in Colon Cancer

Wernicke's syndrome, caused by thiamine deficiency, is most commonly associated with alcoholism but can also occur in patients who are malnourished or have malabsorption of nutrients for other reasons. Since the classic triad of encephalopathy, nystagmus and ataxia occurs simultaneously in only 10–33% of cases, a high index of suspicion is needed in any patient with confusion and memory loss. In this case report, we present a 56-year-old female patient with metastatic colon cancer complicated with enterocutaneous fistula. She developed Wernicke's encephalopathy precipitated by 5-fluorouracil infusion. Replacement with thiamine rapidly reversed her neurologic symptoms and signs

The clinical significance of preoperative plasma fibrinogen levels and platelet counts in resectable colon cancer

Background and aim Several aspects of the correlation between colon cancer and hemostatic markers are still unknown to many researchers in the field. In this study, we evaluated the association, if any, of preoperative platelet (PLT) counts and plasma fibrinogen levels with postoperative lymph node involvement and venous invasion in colon cancer patients. Methods This study retrospectively included eighty patients with colon cancer (mean age 58.09 years; 37% female 63% male). Results Patients with negative lymph nodes and venous invasion showed a significantly lower PLT count and higher fibrinogen level than their counterparts, i.e., patients with positive lymph nodes (p<0.001, all of them) and venous invasion (p<0.001, all of them). The results also showed a positive association of PLT counts and fibrinogen levels with lymphatic invasion (r=0.670, pr=0.639, p<0.001, respectively) and a positive association of PLT counts and fibrinogen levels with venous invasion (r=0.3988, pr=0.5268, p<0.001, respectively). According to the results of the ROC curve analysis, when the PLT count cutoff was 290/mm(3), the sensitivity and specificity were 82% and 86.67%, respectively (AUC = 0.8840, p<0.0001, 95% CI 0.8084-0.9596). When the fibrinogen level cutoff was 310.0 mg/dL, the sensitivity and specificity were 72% and 96.67%, respectively (AUC 0.8790, p <0.0001, 95% CI 0.8067-0.9513). Conclusion The preoperative PLT count and plasma fibrinogen level may be considered key markers to monitor postoperative lymph node involvement and venous invasion in colon cancer patients

The effect of methotrexate monotherapy on treatment-resistant idiopathic granulomatous mastitis patients

Background: Idiopathic granulomatous mastitis (IGM) is a disease of unknown etiology, involving a chronic inflammatory process, characterized by noncaseating granuloma formation. IGM can mimic a tumor clinically and radiologically. Since we are a tertiary referral center, most of our patients (n = 56, 87.5%) are secondary admissions who have previously had antibiotics and steroid treatments; therefore, we accept these patients as resistant cases. Here, we aim to present our single-center series of 64 patients with resistant IGM who underwent methotrexate monotherapy. To the best of our knowledge, our study includes the highest number of patients described in the literature with IGM who have undergone this treatment

The Effect of Menstrual Cycle Phase on the Prognostic Factors in Patients with Premenopausal Breast Tumors

Background: Estrogen receptor and progesterone receptor positivity and c-erbB2 gene expression levels are important in determining breast cancer development and aggression. Although the importance of hormonal factors in tumor cell proliferation, migration and differentiation is increasing, it needs more evidence. The effect of BC surgery timing during the menstrual cycle on prognosis remains controversial. In order to clarify this hypothesis, we aimed to determine the importance of adjusting the timing of surgery according to the menstrual cycle by examining the relationship between estrogen receptor, progesterone receptor, c-erbB2 gene and the menstrual cycle phase in patients with premenopausal breast cancer

Preoperative Fibrinogen and Hematological Indexes in the Differential Diagnosis of Idiopathic Granulomatous Mastitis and Breast Cancer

Background and Aim: Studies on hematological parameters in the differential diagnosis of idiopathic granulomatous mastitis (IGM) and breast cancer (BC) are limited. This study investigated whether preoperative fibrinogen and hematological indexes can be used in the differential diagnosis of patients with IGM and early-onset BC. Methods: Fifty patients with BC, 55 patients with IGM, and 50 healthy volunteer women were included in the study. Results: There was a statistically significant difference between the IGM and the BC with respect to fibrinogen, fibrinogen/albumin (Fib/Alb) ratio, C-reactive protein (CRP), white blood cells (WBC), neutrophils, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and monocyte values. When fibrinogen (p < 0.001), the Fib/Alb ratio (p < 0.001), CRP (p < 0.001), WBC (p < 0.001), neutrophil (p < 0.001), NLR (p < 0.001), monocyte (p = 0.008), and 2-hour sedimentation rate (p < 0.001) were compared between the groups, the highest levels were found in the IGM group. There was a negative relationship between CRP and albumin, and a positive relationship was observed between CRP and WBC, NLR, PLR, and 2-h sedimentation rate. CRP had the highest sensitivity (95%), whereas the Fib/Alb ratio (86%) had the highest specificity. Patients with recurrent IGM had increased fibrinogen, Fib/Alb, CRP, neutrophils, NLR, and 2-h erythrocyte sedimentation rate (ESR) and decreased lymphocyte levels compared to non-recurrent patients. Conclusions: Preoperative CRP, albumin, fibrinogen, Fib/Alb, WBC, neutrophil, NLR, monocyte, and 2-h ESR have considerable potential to be early and sensitive biomarkers of IGM caused by inflammation compared to BC. These parameters also have a significant effect on the recurrence of the disease, suggesting their potential as a practical guide for the differential diagnosis of BC from IGM

Idiopathic granulomatous mastitis associated with erythema nodosum may indicate a worse prognosis

Introduction Idiopathic granulomatous mastitis (IGM) is a chronic inflammatory breast disease of unknown etiology, and erythema nodosum (EN) is a rare extramammary manifestation of this entity characterized by reddish, tender nodules of the lower legs. We aimed to investigate whether the association of IGM with EN has a role as a prognostic indicator. There are few case reports, and only 1 original article including 12 IGM patients with EN has been reported. Methods We present 43 women with IGM coexisting with EN and 43 with a diagnosis of IGM only, who were randomly selected from 610 patients for a control group. To the best of our knowledge, this paper comprises the first comparative study of the coexistence of IGM and EN to be reported in the literature. Results Our findings show that the association of IGM with EN indicates a more aggressive disease course. White blood cells, erythrocyte sedimentation rate, and C-reactive protein were significantly higher in the EN-positive group (P < .05). Arthralgia, breast feeding, fistula distribution and recurrence distributions were significantly higher in the EN-positive group (P < .05). Conclusion Since fistula distribution and recurrence rates were higher in EN-positive group, association of IGM with EN may be an indictor of a worse prognosis. The present study highlights the importance of dermatological care. All physicians should not neglect questioning breast complaints in patients with EN since EN may be caused by IGM

Association between Bone Mineral Density and Bone Turnover Markers in Breast Cancer Patients and Bone-Only Metastasis

Background and Objectives: The aim of this study was to determine the influence of bone turnover markers, namely the N-terminal cross-linking telopeptide (NTx) and alpha C-terminal cross-linking telopeptide of type I collagen (alpha-CTx), in detecting bone metastasis (bone-only) in breast cancer (BC) patients, as well as to determine whether this effect is related to changes in bone mineral density (BMD). Materials and Methods: The participants in this study comprised 30 postmenopausal BC patients with bone metastases (age range: 59.56 +/- 9.02), 20 postmenopausal BC patients without bone metastases (age range: 55.30 +/- 11.55), and 20 healthy postmenopausal female controls (age range: 55.55 +/- 5.85). Bone turnover markers (serum NTx and urine alpha-CTx) were measured using the ELISA method. A densitometer using dual-energy X-ray absorptiometry (DEXA) was used to analyze the BMD, and tumor markers were measured using the chemiluminescent immunometric assay. Results: The corresponding levels of serum NTx (p = 0.004), parathyroid hormone (PTH) (p = 0.001), and urine alpha-CTx (p < 0.001) of BC patients were found to be higher than the standard levels. After the BC patients were divided into subgroups on the basis of the presence of metastasis, the urine alpha-CTx levels (p = 0.001) were seen to be at critically high levels in those patients suffering from BC with metastasis. Though the BMD values in the lumbar spine (p < 0.001) and femoral neck (p = 0.001) were found to be significantly low in BC patients, no statistically substantial difference in the BMD levels of BC patients suffering from metastasis was observed. It was observed that urine alpha-CTx (specificity: 70%; sensitivity: 85%) values are critical factors that differentiate BC patients with metastasis from BC patients without metastasis. Conclusions: We found that alterations in bone turnover could be detected by using the values of urine alpha-CTx while differentiating BC patients with metastasis from BC patients without metastasis. Using the biochemical markers of bone turnover and BMD together would be pertinent for determining the level of metastasis present and examining the efficiency of bone density preservation therapy. Ideally, BMD measurement would be evaluated together with biochemical markers
