Background: Lung cancer remains the leading cause of cancer-related mortality globally, predominantly affecting older individuals. Despite the increasing use of immune checkpoint inhibitors (ICIs) like nivolumab in non-small cell lung cancer (NSCLC), the efficacy and safety in elderly patients, particularly those aged 65 and above, remain underexplored due to their underrepresentation in clinical trials. Methods: This retrospective study analyzed data from 60 elderly patients (≥65 years) with metastatic NSCLC who received nivolumab as second-line or later therapy between January 2020 and May 2023. Results: The median age was 67 years, with a predominance of males (78%). Nivolumab was administered for a median of 8 cycles, with 33.3% of patients receiving 15 or more cycles. The median OS was 23 months, and the 1-, 3-, and 5-year survival rates were 93.3, 54.1, and 18.6%, respectively. Multivariate analysis identified adenocarcinoma histology, fewer than 15 cycles of nivolumab, and non-response to prior therapies as independent predictors of poor OS. Nivolumab treatment was generally well-tolerated, with 45% of patients experiencing at least grade 1 toxicity. Conclusions: Nivolumab is effective and well-tolerated in elderly patients with metastatic NSCLC, providing survival benefits comparable to those observed in younger populations. The number of treatment cycles and initial response to therapy are key determinants of survival, underscoring the importance of continued treatment in this age group. [ABSTRACT FROM AUTHOR]

Background and Objectives: Lung cancer is the leading cause of cancer-related deaths. Spread through air spaces (STAS) is an adverse prognostic factor that has become increasingly known in recent years. This study aims to investigate the impact of STAS presence on overall survival (OS) and disease-free survival (DFS) in patients with surgically resected stage IA-IIIA lung cancer and to identify clinicopathological features associated with STAS. Materials and Methods: This research involved 311 lung cancer surgery patients. The relationship between the presence of STAS in the patients' surgical pathology and OS and DFS values was examined. Clinicopathological features associated with the presence of STAS were determined. Results: There were 103 (33%) STAS-positive patients. Adenocarcinoma histological subtype, perineural invasion (PNI), and lymphovascular invasion (LVI) were significantly correlated with being STAS positive. STAS significantly predicted DFS and OS. One-year and five-year DFS rates were significantly lower in the STAS-positive group compared to the STAS-negative group (65% vs. 88%, 29% vs. 62%, respectively, p ≤ 0.001). Similarly, one-year and five-year OS rates were significantly lower in the STAS-positive group compared to the STAS-negative group (92% vs. 94%, 54% vs. 88%, respectively, p ≤ 0.001). In multivariate analysis, STAS was found to be an independent prognostic factor for both DFS and OS (HR: 3.2 (95%CI: 2.1–4.8) and 3.1 (95%CI: 1.7–5.5), p < 0.001 and <0.001, respectively). Conclusions: In our study, STAS was found to be an independent prognostic biomarker in operated stage IA-IIIA lung cancer patients. It may be a beneficial pathological biomarker in predicting the survival of patients and managing their treatments. [ABSTRACT FROM AUTHOR]

Background and Objectives: Colorectal cancer (CRC) poses a major global health challenge, with high incidence rates and ongoing treatment debates. Adjuvant chemotherapy benefits for high-risk subgroups, particularly stage II disease, remain controversial. This study seeks to clarify this issue by specifically examining the impact of adjuvant chemotherapy on disease-free survival (DFS) and overall survival (OS) in patients diagnosed with T4 colon cancer. Materials and Methods: This retrospective study analyzed patients undergoing radical surgery for T4 colon cancer between 2002 and 2023. Results: Our study of 184 pT4 pN0 colon cancer patients revealed that 79.3% received adjuvant chemotherapy. Multivariate analysis demonstrated significant DFS improvement: a 60% reduction in risk for those who received adjuvant therapy (0.40 95% CI: 0.25–0.62, p < 0.001). Lymphovascular invasion (LVI) and adjuvant treatment were also significantly associated with OS. Adjuvant treatment reduced mortality by 60% (HR: 0.40, 95% CI: 0.23–0.68, p = 0.001). Patients with LVI had a 1.9-fold increase in mortality (HR: 1.94, 95% CI: 1.17–3.20, p = 0.011). These findings underscore the potential value of adjuvant chemotherapy and highlight the importance of treatment completion in managing T4 colon cancer. Conclusions: Our study identifies LVI and adjuvant chemotherapy as key prognostic factors in T4 colon cancer patients. These results support the consideration of adjuvant chemotherapy in this patient population. [ABSTRACT FROM AUTHOR]

Simple Summary: Based on this study, we define a new biomarker termed lymphocyte-to-albumin ratio (LAR) that may predict the prognosis for patients with metastatic NSCLC treated with immunotherapy. This study aims to determine the relationship of the LA index with patients' survival rate through studying the records of 227 patients who were treated with nivolumab after one or multiple cycles of chemotherapy. Therefore, the results showed that a higher LA index is significantly related to better overall survival (OS) and progression-free survival (PFS). Overall, the LA index deserves its merit of being a simple, cost-effective, noninvasive method applicable in NSCLC immunotherapy as a clinically practical tool for predicting treatment outcomes. Objective: Immunotherapies are commonly employed for the treatment of non-small-cell lung cancer (NSCLC). However, predictive biomarkers still need to be improved to predict responses to these agents. The lymphocyte–albumin (LA) laboratory index has not been evaluated before in this patient group. The aim of this study was to analyze the relation between the LA index and the survival rate of metastatic NSCLC patients who had immunotherapy after at least one round of chemotherapy. Methods: The research included 227 patients diagnosed with metastatic NSCLC, who were administered nivolumab after at least one round of chemotherapy. The LA index was calculated by multiplying lymphocyte count and albumin concentration. The optimal threshold values for the index were established by the examination of the ROC curve for both overall survival (OS) and progression-free survival (PFS). Oncological data were obtained retrospectively from patient files, and survival analyses were performed. Results: The median follow-up was 7.9 months. Progression was observed in 129 (56.9%) patients. A total of 97 (42.7%) patients died during the follow-up. The cutoff values of the LA index to predict OS and PFS were determined as 52.87 and 57.67, respectively. The low-LA group had significantly lowered OS and PFS compared to the high-LA group. LA was found to be an independent prognostic factor for PFS (hazard ratio 4.47; 95% confidence interval, 2.73–7.34; p < 0.001) and OS (hazard ratio 6.24; 95% confidence interval, 3.46–11.25; p < 0.001) in the multivariate regression analysis. Conclusions: In this study, we observed that the LA index independently predicts OS and PFS in immunotherapy-treated metastatic NSCLC patients. Its ease of application, low cost, and noninvasive nature make it a potential guide for clinicians in predicting treatment responses and survival. [ABSTRACT FROM AUTHOR]

Introduction: Neoadjuvant chemotherapy (NAC) is extensively employed in breast cancer (BC), primarily for aggressive subtypes like triple-negative and human epidermal growth factor receptor 2 (HER2)-positive BC and in estrogen receptor-positive (ER+)/HER2− BC with high-risk features. In ER+/HER2− BC, pathological complete rates are much lower (<10%), while axillary dissection rates are higher. This study focuses on hormone receptor-positive (HR+)/HER2− BC patients undergoing NAC, examining its impact on pathological complete response (pCR) rates, with specific attention to tumor Ki67 and ER status. Methods: Retrospective data analysis from Kartal Dr. Lütfi Kırdar City Hospital included HR+/HER2− BC patients who received NAC. Clinicopathological factors, NAC response, and surgical outcomes were assessed. Statistical analyses evaluated the association between Ki67, ER status, and pCR. Results: Of 203 patients, 11.8% achieved pCR. Ki67 (p < 0.001) and ER percentage (p < 0.001) significantly correlated with pCR. Higher Ki67 was associated with increased pCR likelihood (HR: 1.03, 95% CI: 1.01–1.05). A Ki67-pCR probability curve revealed a cutoff of 23.5%. ER%-pCR analysis showed decreasing pCR rates with higher ER percentages. Multivariate analysis confirmed Ki67 (p = 0.003, HR: 1.02) and ER percentage (p = 0.019, HR: 0.97) as independent predictors of pCR probability. Conclusion: Consideration of Ki67 and ER percentage aids in NAC decisions for HR+/HER2− BC, identifying patients with high NAC response rates, facilitating axillary preservation, and potentially avoiding axillary dissection. The pCR rates in patients with Ki67 ≤24 are particularly low, especially in patients with a high ER percentage. In these cases, upfront surgery and adjuvant treatment should be considered instead of NAC. [ABSTRACT FROM AUTHOR]

Background: The treatment and escape for metastatic renal cell carcinoma (RCC) has rapidly evolved, particularly with the integration of immune therapies into first-line regimens. However, optimal strategies following progression in first-line immunotherapy remain uncertain. This study aims to evaluate the efficacy and safety of axitinib and cabozantinib as third-line therapies after progression on nivolumab following first-line VEGF-TKI therapy. Methods: Patients with metastatic RCC who progressed on prior nivolumab treatment after receiving first-line VEGF-TKI therapy were included. Data on patient characteristics, treatment regimens, response rates, progression-free survival (PFS), and overall survival (OS) were collected. Statistical analyses were conducted to assess the prognostic factors and treatment outcomes. Results: A total of 46 patients were included who were predominantly male (83%) with clear-cell histology (89%). The median PFS on first-line TKI therapy was 10.2 months. All the patients received nivolumab as a second-line therapy, with a median of 12 cycles. The median second-line PFS was seven months. Third-line therapies included axitinib (24 patients) and cabozantinib (20 patients). The median PFS for axitinib and cabozantinib was six months, with comparable survival outcomes. The IMDC risk group and treatment tolerability were significant predictors of survival in multivariate analysis. Adverse events were manageable, with hypertension, fatigue, and diarrhea being the most common. Conclusion: Axitinib and cabozantinib show promise as third-line therapies post-nivolumab progression in metastatic RCC, though prospective validation is warranted. This study underscores the need for further research to establish treatment standards in this evolving landscape. [ABSTRACT FROM AUTHOR]

Central nervous system (CNS) metastases can be seen at a rate of 30% in advanced stages for patients with non-small cell lung cancer (NSCLC). Growing evidence indicates the predictive roles of driver gene mutations in the development of brain metastases (BM) in recent years, meaning that oncogene-driven NSCLC have a high incidence of BM at diagnosis. Today, 3rd generation targeted drugs with high intracranial efficacy, which can cross the blood–brain barrier, have made a positive contribution to survival for these patients with an increased propensity to BM. It is important to update the clinical and pathological factors reflected in the survival with real-life data. A multi-center, retrospective database of 306 patients diagnosed with driver mutant NSCLC and initially presented with BM between between November 2008 and September 2022 were analyzed. The median progression-free survival (mPFS) was 12.25 months (95% CI, 10–14.5). While 254 of the patients received tyrosine kinase inhibitor (TKI), 51 patients received chemotherapy as first line treatment. The median intracranial PFS (iPFS) was 18.5 months (95% CI, 14.8–22.2). The median overall survival (OS) was 29 months (95% CI, 25.2–33.0). It was found that having 3 or less BM and absence of extracranial metastases were significantly associated with better mOS and iPFS. The relationship between the size of BM and survival was found to be non-significant. Among patients with advanced NSCLC with de novo BM carrying a driver mutation, long-term progression-free and overall survival can be achieved with the advent of targeted agents with high CNS efficacy with more conservative and localized radiotherapy modalities.

Introduction: Testicular germ cell tumors (seminoma/non-seminoma) are the most common carcinomas in young males, comprising approximately 1% of all carcinomas. In stage-I disease, orchiectomy can cure approximately 85% of patients. Post-surgical options are adjuvant therapy and active surveillance. Our study examined the effects of management options on stage-I seminoma patients followed in our center. Methods: We evaluated the patients with stage-I testicular seminoma who underwent radical orchiectomy and followed up in the oncology center between 2001 and 2022. The outcomes of management options, survivals were retrospectively analyzed. The prognostic significance of risk factors for relapse on survival was evaluated. Results: Of the 140 patients with stage-I seminoma, 49 (35%) were treated with adjuvant therapy, and 91 (65%) underwent surveillance. The median follow-up duration was 37 months. During the follow-up period, nine patients in the active surveillance group and four in the adjuvant therapy group had a recurrence. There was no statistically significant difference between the two groups (p = 0.67). In the surveillance group, the univariate and multivariate analyzes identified the presence of lymphovascular invasion (p = 0.005, HR: 0.13) as significant prognostic factor for disease-free survival (DFS). In the surveillance cohort, the 5-year DFS rate was 60% for patients with lymphovascular invasion and 93% for those without. There was statistical significance between the two groups (p = 0.003). Conclusion: Our study shows that adjuvant therapy does not significantly improve DFS compared to surveillance in patients. In addition, it has been shown that lymphovascular invasion is an important prognostic indicator for DFS in determining the treatment strategy. [ABSTRACT FROM AUTHOR]

Background and Objectives: This investigation aimed to determine the impacts of concurrent proton pump inhibitors (PPIs) on progression-free survival (PFS) in patients with hormone receptor-positive and HER2-negative metastatic breast cancer managed with palbociclib or ribociclib as either the initial or subsequent line of therapy option. Materials and Methods: In this retrospective study, patients were classified as "concurrent PPIs" if PPIs were given for at least two-thirds of the palbociclib or ribociclib therapy period, and "no concurrent PPIs" if no PPIs were given during the period of palbociclib or ribociclib therapy. Each patient was also classified as endocrine-sensitive or endocrine-resistant according to the duration of previous endocrine responses. "Concurrent PPIs" and "no concurrent PPIs" groups were compared with each other in terms of PFS. This comparison was performed for both ribociclib and palbociclib groups. Results: The research included 220 patients in total. The PFS of 57 patients on palbociclib using concomitant PPIs was 14.4 months. Among 63 patients using palbociclib without concomitant PPIs, the PFS was 15.8 months. No statistically significant difference was found with PPI use (p = 0.82). Among 29 patients using ribociclib concurrently with PPIs, the PFS was 22.4 months. Among 71 patients using ribociclib without PPIs, the PFS was 20.2 months. No statistically significant difference was found with PPI use (p = 0.40). Conclusion: The results of our investigation showed that concomitant use of the most commonly used PPIs in the study (lansoprazole, pantoprazole, and esomeprazole) with palbociclib or ribociclib did not have any detrimental effects on PFS. Where appropriate, PPIs can be used concurrently with palbociclib and ribociclib. However, the effect of PPIs on cycling-dependent kinase 4/6 inhibitors deserves further investigation.

Aim: Mesenteric ischemia is a rare, highly fatal, surgical emergency. In addition to open surgical (OS) intervention, endovascular treatment (ET) was also recommended for treatment in last years. Surgical resection becomes inevitable in the cases of intestinal ischemia. We aimed to assess patient-related factors and compare treatment outcomes in mesenteric ischemia treated by OS and ET. Material and Methods: Patients treated for mesenteric vascular occlusion at our hospital between 2013 and 2018 were retrospectively evaluated. Duration of symptoms, time from symptom onset to treatment, treatment used and surgery used, re-laparotomy need, duration of intensive care unit stay, duration of hospital stay, and 30-day and 1-year mortality rates were evaluated. Results: Twenty patients with mesenteric ischemia were evaluated. The OS group had a significantly higher CCI score than the ET group (p<0.05). The most common comorbidities in the OS and ET groups were coronary artery disease and hypertension, respectively. The duration of symptoms and time from symptom onset to treatment were significantly shorter in the OS group than the ET group (p<0.05). The OS group most commonly had SMA emboli while the ET group most common had chronic SMA occlusion (p<0.05). Thirty-day and 1-year mortality rates were significantly greater in the OS group than the ET group (p<0.05). Conclusion: Mesenteric ischemia is a highly morbid and fatal condition. ET significantly reduces morbidity and mortality in the face of signs of intestinal ischemia. On the other hand, OS would be inevitable for patients with signs of diffuse peritoneal irritation or those with suspected intestinal necrosis. [ABSTRACT FROM AUTHOR]

Aim: Examining the effect of surgeon's fatigue on early term patency and complications of arteriovenous fistula (AVF). Material and Methods: AVFs created for hemodialysis in patients with end-stage renal failure were included in the study. The patients were divided into 2 groups as those operated in the first operation of that day (Group 1) and those operated after the first or second operations (Group 2). The patients were compared with respect to clinical, demographics, postoperative, surgical variables, and operation duration. Results: A total of 100 patients underwent AVF operation. No statistically significant differences were found between the groups with respect to clinical, demographic, surgical, and postoperative variables. Efficiency of dialysis was found to be higher and complication rate lower in Group 1. But no statistical significance was obtained in terms of early dialysis efficiency and complication rates in between the groups (p>0.05). Complication rate was higher in Group 2 when compared according to operation time as 120, 120-240, and 240< minutes. But no statistical significance was obtained in this manner (p>0.05). Conclusions: Although not statistically significant, surgical fatigue factor and long operation time increase the rate of early complications and reduce early dialysis efficiency. We think that early term patency of AVF can also be affected by the complication rate. The effect of this variable can be statistically significant with studies having larger sample size.

The purpose of this study was to analyze the clinical features and demographic data of patients with idiopathic granulomatous mastitis (IGM) and to compare the results of conservative versus surgical treatment protocols. The demographic data, clinical findings, microbiological and pathologic features, scanning and treatment methods, recurrence, and recovery rates of 77 patients were analyzed retrospectively. The patients were divided into two groups based on the type of treatment received. Core biopsies were used to diagnose 37 patients: 26 using incisional biopsies and 14 using excisional biopsies. Of the patient population with IGM, 31 were treated with surgical excision, one with a simple mastectomy, and one with a subcutaneous mastectomy combined with a breast implant, whereas 44 were treated with steroids. The recovery rates of the 44 patients who were treated conservatively were 6 (1–15) months while for the 33 patients who were treated surgically, it was 1 (1–5) month (p = 0.001). Nine patients from the conservative treatment group experienced a recurrence while there were no recurrences in the surgically treated group (p = 0.009). Among all patients, the recurrence rate was 11.7% (9/77) while the average follow‐up period was 16.57 ± 18.57 months. As a comparative study between conservative treatment protocols and surgical ones for patients with idiopathic granulomatous mastitis (IGM), this study is the largest to date. A wide surgical excision is the preferred approach for treating patients with IGM because of the low recurrence rate. [ABSTRACT FROM AUTHOR]

The purpose of this report was to determine the effectiveness of therapeutic plasma exchange (TPE) in preoperative preparation of patients with thyrotoxicosis scheduled for either thyroid or nonthyroid surgery. We retrospectively reviewed 11 patients with thyrotoxicosis and those who prepared surgery with plasmapheresis between 1999 and 2008 at our institution. Ten patients underwent thyroid surgery and one patient was operated for femur fracture during antithyroid drug treatment. The indications for plasmapheresis in all patients with severe thyrotoxicosis were poor response to medical treatment (seven patients), agronulocytosis due to antithyroid drugs (three patients), iodine-induced thyrotoxicosis (Jodd Basedow effect in one patient), and rapid preparation for urgent orthopedic operation (one patient). After TPE, we observed a marked decrease in free thyroxin (FT3) and free triiodothyronin (FT4) levels; however, the decline in the biochemical values were not statically significant ( P > 0.62, P > 0.15). Although both FT3 and FT4 levels remained above the normal limits in two of 11 patients, the signs and symptoms of thyrotoxicosis improved in all patients and no thyroid storm observed during the perioperative period. TPE can be considered a safe and effective alternative to prepare patients with thyrotoxicosis for surgery when drug treatment fails or is contraindicated and when emergency surgery is required. J.

FLT3 and its ligand (FL) are one of the regulators of normal hematopoiesis. Ligand-independent activation of FLT3 occurs in about 30% of acute myeloid leukemia cases and is one goal for selectively targeted therapies. However, the function of FLT3/FL in the regulation of non-malignant immature hematopoietic cells is poorly characterized. In order to elucidate the role of FLT3 in normal hematopoiesis, human adult CD34+ hematopoietic progenitor cells were cultured in cytokine-supplemented liquid culture in the presence or absence of FLT3 inhibition by CEP-701 (lestaurtinib). Total cell number, lineage-committed, and primitive progenitors and apoptosis were assayed. FLT3 expression and FL secretion in various conditions were analyzed by fluorescent activated cell sorter and enzyme-linked immunosorbent assay. Effects of nonspecific targeting of FLT3 were evaluated with addition of imatinib (Gleevec®) to cell cultures. It is demonstrated that FLT3 inhibition impaired cell and progenitor cell growth and increased the rate in apoptosis. Effects were observed independent of addition of FL. The dose-dependent growth inhibition was partially equalized by inhibiting FL with a neutralizing antibody. FLT3 inhibition resulted in markedly increased production of FL by cultured CD34+ cells as well as upregulation of FLT3 expression. Imatinib mimicked effects of selective FLT3 inhibition. In conclusion, FLT3 and its ligand regulate proliferation of hematopoietic progenitor cells in an autocrine/paracrine manner Nonspecific inhibition of FLT3 may contribute to hematotoxicity caused by imatinib treatment.

In mice, differential regulation of CXC chemokine receptor expression in circulating polymorphonuclear neutrophils (PMNs) undergoing senescence results in homing to the bone marrow. However, the role of this compartment and of the chemokine receptor CXCR4 is still under discussion, and only scarce data exist about CXCR4 function in human PMN. In our study, we provide evidence that also in human neutrophils, expression (cell surface and mRNA), chemotactic and signaling functions of the homing-related chemokine receptor CXCR4 are upregulated during aging in vitro, independent of addition of stimulatory cytokines (TNF, IL-1, IL-8, G-CSF). In contrast, interleukin-8 receptors are downmodulated (CXCR2) or remain unchanged (CXCR1), suggesting that human PMNs undergoing senescence acquire a phenotype that impairs inflammatory extravasation and favors homing to the bone marrow or other tissues involved in sequestration. Partially retained responsiveness to interleukin-8 may be important for neutrophil function when senescence occurs after extravasation in inflamed tissues. [ABSTRACT FROM AUTHOR]

Ligand-mediated activation of the FMS-like tyrosine kinase-3 (FLT3) receptor is important for normal proliferation of primitive hematopoietic cells. FLT3 expression in the bone marrow is restricted to CD34+ cells and a subset of dendritic precursors. FLT3, as a member of the type III RTK subfamily, is closely related to c-kit, c-FMS, and PDGFα/β and is an unspecific target of tyrosine kinase inhibitors, such as imatinib. Activating mutations of FLT3 play an important role in leukemogenesis and their presence is associated with poor prognosis in acute myeloid leukemia (AML). Targeting the mutation by inhibiting the tyrosine kinase activity of FLT3 is a promising therapeutic option in the treatment of AML patients. CEP-701 (Lestaurtinib), an indocarbazole derivate, is an FLT3 tyrosine kinase inhibitor. In this study, we investigated the effect of FLT3 kinase inhibition on normal hematopoietic stem and progenitor cells in vitro. FLT3 inhibition in normal CD34+ cells resulted in a dose-dependent inhibitory effect in cell expansion. In contrast, progenitor cell function remained nearly unaffected. Blocking the FLT3 ligand by a neutralizing antibody partially restored the effects of FLT3 inhibition. These findings might explain hematotoxicity of tyrosine kinase inhibitors such as imatinib.

The objective of this study was to present the etiology, clinical presentation, diagnosis, and management for 14 cases of gossypiboma [retained surgical sponge (RSS)] treated at a single center and to emphasize the importance of this potential complication. Data for 14 cases of RSS treated between January 1999 and December 2004 were retrospectively assessed. The details of preoperative evaluation, demographic features, and operative findings were recorded. Use of, and findings from, abdominal x-ray, ultrasonography, computed tomography, magnetic resonance imaging, and upper-gastrointestinal endoscopy were also noted. In all cases, the RSS was surgically removed. Thirteen of the 14 patients were symptomatic, and the most frequent finding was nonspecific abdominal pain and intestinal obstruction. Four patients required urgent surgery because the sponges were causing intestinal obstruction or intraabdominal sepsis. Based on history, physical examination findings, and diagnostic imaging, RSS was diagnosed preoperatively in five of the patients. Postoperative complications, including surgical site infection and evisceration, occurred in five cases. RSS can lead to significant medical and legal problems between the patient and the doctor. RSS may be incorrectly diagnosed preoperatively, which can lead to unnecessary invasive diagnostic procedures and operations. Strict measures must be taken to prevent this complication.

The role of parasitic infection in the aetiology of acute appendicitis has been discussed for more than 100 years. The aim of this retrospective study was to determine the prevalence of parasitic infection in surgically removed appendices, and to identify whether this type of infection is associated with appendicitis. 104 appendices were removed from patients clinically diagnosed with acute appendicitis, and 30 were removed in the course of other surgical procedures. All the operations were performed at Baskent University Adana Hospital between January 1999 and December 2004. Enterobius vermicularis was identified in 4 (3.8%) appendices from patients with clinical appendicitis, and Entamoeba histolytica was detected in 1 (1.0%) appendix from this group. No parasites were found in the 30 appendices that were removed during other surgical procedures. Specimens from 3 of the 4 appendices with E. vermicularis showed no histological evidence of acute inflammation. It is concluded that parasites in the appendix may produce symptoms which resemble acute appendicitis, but parasitic infection rarely causes acute appendicitis. [ABSTRACT FROM AUTHOR]

Small bowel phytobezoars are rare and are almost always obstructive. The literature contains few reports on the radiological findings for primary small bowel bezoars. There is also very little published on CT results with this lesion, but the features of the scan are characteristic. We present the CT findings in a patient with an obstructive small bowel phytobezoar, and emphasize the diagnostic value of CT. [ABSTRACT FROM AUTHOR]

The article presents a study which evaluates the medical distinction between dermatoses of the nipple and Paget disease. It discusses the cases of 24 patients who were admitted at the Baskent University Adana Hospital in Adana, Turkey for dermatoses of the nipple between January 2002 and December 2007. It highlights the results of the study, highlighting that dermatoses of the nipple can be confused for benign skin disorders, while benign lesions can be mistaken with cancerous conditions.
