Pulmonary echinococcosis mimicking multipl lung metastasis of breast cancer: The role of fluoro-deoxy-glucose positron emission tomography

<p>Abstract</p> <p>Background</p> <p>Echinococcosis is still a serious problem particularly in endemic areas such as South and Central America, Mediterranean countries, and Russia. Furthermore, hydatid cysts of the lung are often indistinguishable from a variety of other pulmonary lesions such as lung tumors</p> <p>Case presentation</p> <p>We herein present a 56 year old woman with breast cancer who presented with bilateral pulmonary nodules due to echinococcosis granulosis that mimicked metastatic breast cancer to the lung.</p> <p>Conclusion</p> <p>During the evaluation of the malignancies which could metastasize to the lung, it must be kept in mind that the appearance of bilateral multiple pulmonary masses can also be the sign of a pulmonary echinococcosis especially in endemic areas. FDG-PET with its known high negative predictive value in characterizing indeterminate pulmonary nodules >1 cm is very helpful to characterize this kind of lesions.</p

A RARE PHENOMENON CREATING DILEMMA FOR THE SURGEON:PNEUMOPERITONEUM AFTER COLONOSCOPY

Pneumoperitoneum is free air existence in abdomen and usually caused by the perforation in gastrointestinal system. Peptic ulcer disease is the most common cause of perforation and pneumoperitoneum. The presence of free air in abdomen usually indicates emergency surgery. However, surgical approach is not required in some cases of pneumoperitoneum if there is no evidence of perforation and no sign of peritoneal irritation. Herein, we present an 82-year–old male patient who had pneumoperitoneum after colonoscopy and treated non-surgically

Persistent High Postoperative Carcinoembryonic Antigen in Colorectal Cancer Patients- Is it Important?

INTRODUCTION: Evaluation of pre- and postoperative serum CEA levels together has seldom been assessed for the prognosis of colorectal cancer (CRC). OBJECTIVE: To concurrently evaluate pre- and postoperative CEA as factors of relapse and survival. METHODS: The study consisted of 114 patients who had undergone surgery from February 2002 to June 2006 for CRC. All patients were classified into four groups according to their pre- and postoperative CEA levels. Data obtained for clinicopathologic parameters, lymph node metastasis, stage, recurrence, and CEA levels were analyzed to determine their association with survival. Multivariate analysis by the Cox proportional hazard regression model was performed to identify the independent prognostic factors associated with survival. RESULTS: Postoperative serum CEA levels remained high in Group 3 (n = 32). Nineteen patients (59.3%) demonstrated a detectable cause for persistent high CEA levels, while the reasons for those in the other thirteen patients (40.6%) remained obscure. Abnormal preoperative CEA levels significantly correlated with the depth of tumor invasion, lymph node metastasis, TNM stage, and recurrence (p < 0.05). Abnormal postoperative CEA levels were significantly related to the depth of tumor invasion, TNM stage, and postoperative relapse (p<0.05). Patients in Group 3 demonstrated the worst survival rate. Abnormal postoperative CEA levels, lymph node metastasis, and location of the tumor were independent prognostic factors for survival. CONCLUSION: The survival of patients with high postoperative CEA levels due to unknown reasons may be extended if they are exhaustively tested with sensitive diagnostic methods and treated at an early stage

Unpublished Mediterranean and Black Sea records of marine alien, cryptogenic, and neonative species

To enrich spatio-temporal information on the distribution of alien, cryptogenic, and neonative species in the Mediterranean and the Black Sea, a collective effort by 173 marine scientists was made to provide unpublished records and make them open access to the scientific community. Through this effort, we collected and harmonized a dataset of 12,649 records. It includes 247 taxa, of which 217 are Animalia, 25 Plantae and 5 Chromista, from 23 countries surrounding the Mediterranean and the Black Sea. Chordata was the most abundant taxonomic group, followed by Arthropoda, Mollusca, and Annelida. In terms of species records, Siganus luridus, Siganus rivulatus, Saurida lessepsianus, Pterois miles, Upeneus moluccensis, Charybdis (Archias) longicollis, and Caulerpa cylindracea were the most numerous. The temporal distribution of the records ranges from 1973 to 2022, with 44% of the records in 2020–2021. Lethrinus borbonicus is reported for the first time in the Mediterranean Sea, while Pomatoschistus quagga, Caulerpa cylindracea, Grateloupia turuturu, and Misophria pallida are first records for the Black Sea; Kapraunia schneideri is recorded for the second time in the Mediterranean and for the first time in Israel; Prionospio depauperata and Pseudonereis anomala are reported for the first time from the Sea of Marmara. Many first country records are also included, namely: Amathia verticillata (Montenegro), Ampithoe valida (Italy), Antithamnion amphigeneum (Greece), Clavelina oblonga (Tunisia and Slovenia), Dendostrea cf. folium (Syria), Epinephelus fasciatus (Tunisia), Ganonema farinosum (Montenegro), Macrorhynchia philippina (Tunisia), Marenzelleria neglecta (Romania), Paratapes textilis (Tunisia), and Botrylloides diegensis (Tunisia).peer-reviewe

A Rare Cause of Acute Abdomen: Perforation of Duodenal Diverticulum Containing Ectopic Pancreatic Tissue

Perforation is a rare but serious complication of a duodenal diverticulum and often presents itself with nonspecific symptoms and signs. Ectopic pancreatic tissue within a duodenal diverticulum is another rare situation. In this article, we report a case of an 87 year-old woman who presented with spontaneous perforation of the duodenal diverticulum. Operative resection and simple closure of the duodenum was performed. Ectopic pancreatic tissue was observed within the diverticulum at histological evaluation

Prognostic Value of Lymph Node Ratio for Colorectal Cancer

Objective: This study was designed to assess the prognostic value of lymph node ratio (LNR) in patients with nonmetastatic colorectal cancer treated with radical resection

Body Image and Cosmesis After Laparoscopic or Open Appendectomy

Introduction: Minimally invasive techniques, such its laparoscopic appendectomy (LA), are thought to produce better cosmetic results. The aim of this study was to evaluate the body image and cosmesis of patients after both LA and open appendectomy (OA)

Coexistence of pancreatic tuberculosis with systemic brucellosis: a case report

Isolated pancreatic tuberculosis is an extremely rare clinical entity and is difficult to diagnose particularly in immunocompetent individuals. Clinical findings and symptomatology of brucellosis are often similar to tuberculosis thus making the differentiation amongst the two entities difficult. We report a case of pancreatic tuberculosis with systemic brucellosis in a 29 year old veterinarian who presented with epigastric pain and loss of appetite. Initial investigations revealed leukocytosis with moderately elevated transaminase, gamma glutamyl transferase, amylase and lipase levels. Imaging studies revealed an anechoic multiloculated cyst in the body and tail of the pancreas. Given the patient's occupational risk coupled with the presence of a positive Brucella agglutination test (with a titer of 1:320); a diagnosis of pancreatitis secondary to brucellosis was given. In addition to standard pancreatitis therapy of bowel rest with intravenous fluid/electrolyte replacement, anti-brucellosis therapy was also administered. The patient's initial response to therapy was positive however, 6 weeks into therapy, his abdominal pain recurred and repeat CT scan revealed the development of a pseudocyst in the pancreas. After failing a second attempt at conservative supportive therapy, the patient underwent an explorative laparotomy. Histological examination of the resected pancreatic specimen showed necrosis and was positive for tuberculosis by polymerase chain reaction. Herein, we describe the first case reported in the medical literature of the coexistence of systemic brucellosis with pancreatic tuberculosis. We suggest that the possibility of the coexistence of brucellosis with tuberculosis be kept in mind when assessing pancreatitis patients in endemic regions and in individuals with occupational risk hazards
