    We report a case of synchronous primary colonic adenocarcinoma and malignant mesothelioma. A 61-year-old male presented with a six-month history of fatigue and weight loss. An abdominal computed tomography (CT) scan showed a 5.8 cm partially obstructing mass in the cecum with ascites and peritoneal thickening. A biopsy of the large mass showed an adenocarcinoma. Because the patient was clinically thought to be a T4 colon carcinoma with peritoneal metastatic lesions (M1), prior to initiating chemotherapy, a debulking right hemicolectomy was performed. Resection of the colon and ileum revealed a T3N0 colonic mucinous adenocarcinoma and concurrent diffuse malignant peritoneal mesothelioma. Presenting synchronous colonic and peritoneal mesothelial primary malignancies are exceedingly rare but must be considered to prevent incorrect clinical staging. PMID:24963429

    PubMed Central

    2014-01-01

    Background Gastric duplication cysts are rare congenital abnormalities, and malignant transformation of these duplications is also thought to be rare. Case presentation During a routine health checkup, a 28-year-old man underwent abdominal sonography followed by computed tomography (CT) with contrast agent, which revealed a cystic lesion with no enhancement. Laparoscopic surgery showed a 10 × 10 cm cyst adhering to the gastric corpus. However, attempts to remove the lesion en bloc were unsuccessful, and the ruptured cyst had contaminated the peritoneal cavity. Gastric duplication was diagnosed from microscopic examination of the cyst. Seven months later, the patient suffered a progressive increase in ascites, and repeated cytological analysis showed small nests of adenocarcinoma cells, with primary lesion unknown. Diagnostic laparoscopy showed multiple white nodules scattered over the surface of the liver, greater omentum, and peritoneum. Biopsy of the omental nodules confirmed adenocarcinoma, while carcinomatosis was diagnosed in the peritoneum. Conclusions Clinical presentation and chronological developments indicated that the malignancy probably originated from the gastric duplication cyst. This case highlights the importance of accurate preoperative diagnosis and optimal surgical management for gastric duplication as well as considering the potential existence of malignant transformation during surgical evaluation of adult patients with gastric duplication cysts.

  8. CDX-2 Expression in Primary Lung Adenocarcinoma.

    Cowan, Morgan L; Li, Qing K; Illei, Peter B

    2016-01-01

    Adenocarcinoma with enteric differentiation is a rare subtype of lung adenocarcinoma that is recognized as a variant type of primary adenocarcinoma in the 2015 World Health Organization classification of lung tumors. Published immunohistochemistry studies show variable staining pattern for CDX-2 ranging from positivity in 71% of the cases to no staining. As little is known about CDX-2 expression in lung adenocarcinomas lacking histologic features of enteric differentiation, our aim was to determine the rate of CDX-2 positivity in non-enteric-type lung adenocarcinomas. We performed immunohistochemistry for CDX-2, CK7, CK20, TTF-1, napsin A, and p40 using 4-μm sections of a previously constructed tissue microarray containing 93 primary lung adenocarcinomas that lack morphologic evidence of enteric differentiation. The cohort included 22 well, 54 moderately, and 17 poorly differentiated tumors (55 female, 38 male; age range: 42 to 86, median: 64.5). All 93 tumors were strongly CK7 positive, whereas variable CK20 staining was seen in 4 tumors (1 strong, 1 moderate, and 2 focal). Both TTF-1 and napsin A were positive in 81 of 93 (87%) tumors with only 6 of 93 (6.5%) tumors negative for both the markers. Eleven tumors were CDX-2 positive (5 strong, 3 moderate, and 3 weak), all of which were also TTF-1 and napsin A positive and p40 negative. One CDX-2-positive tumor showed focal CK20 staining. Mutation studies for EGFR/K-ras/ALK were performed in four CDX-2-positive tumors and detected a K-ras mutation in one of them. CDX-2 positivity can be seen in a subset (12%) of lung adenocarcinoma. These tumors are CK7, TTF-1, and napsin A positive and p40 negative. Focal CK20 staining is only seen in rare cases. CDX-2 positivity should not be used as the only criteria to exclude lung origin.

    2015-01-01

    Cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) is a radical but effective treatment option for select peritoneal malignancies. We sought to determine our early experience with this method for peritoneal carcinomatosis secondary to mucinous adenocarcinomas of appendiceal origin. As such, we performed a retrospective clinical study of 30 consecutive patients undergoing CRS with planned HIPEC at the Princess Alexandra Hospital, between June 2009 to December 2012, with mucinous adenocarcinomas of the appendix. CRS was performed in 30 patients, 13 received HIPEC intraoperatively and 17 received early postoperative intra-peritoneal chemotherapy (EPIC) in addition. Mean age was 52.3 years and median hospital stay was 26 days (range 12–190 days). Peritoneal cancer index scores were 0–10 in 6.7% of patients, 11–20 in 20% of patients and >20 in 73.3% of patients. Complete cytoreduction was achieved overall in 21 patients. In total, 106 complications were observed in 28 patients. Ten were grade 3-A, five were grade 3-B and one grade-5 secondary to a fatal PE on day 97. In patients who received HIPEC, there was no difference in disease-free survival (P = 0.098) or overall survival (P = 0.645) between those who received EPIC versus those who did not. This study demonstrates that satisfactory outcomes with regards to morbidity and survival can be achieved with CRS and HIPEC, at a single-centre institution with growing expertise in the technique. Our results are comparable with outcomes previously described in the international literature. PMID:25594636

    Although Crohn's disease has been associated with an increased risk of small bowel adenocarcinoma, primary adenocarcinoma arising from an ileostomy is a complication that has been rarely documented in Crohn's disease. Chronic small bowel inflammation may lead to development of malignancy through the dysplasia-carcinoma sequence. We report a case of a 61-year-old woman with Crohn's ileocolitis diagnosed with a primary adenocarcinoma at the ileostomy with metastases to the liver 47 years after proctocolectomy, and review the literature.

    Although Crohn's disease has been associated with an increased risk of small bowel adenocarcinoma, primary adenocarcinoma arising from an ileostomy is a complication that has been rarely documented in Crohn's disease. Chronic small bowel inflammation may lead to development of malignancy through the dysplasia-carcinoma sequence. We report a case of a 61-year-old woman with Crohn's ileocolitis diagnosed with a primary adenocarcinoma at the ileostomy with metastases to the liver 47 years after proctocolectomy, and review the literature.

    Between 1956 and 1971, a total of 74 cases of adenocarcinoma of the cervix was treatedin the Division of Radiation Therapy of the University of Maryland Hospital. Radical radiation therapy was followed by routine surgery early in the study;after 1967, surgery was used only for radiation failure. The likelihood of local control and 5-year survival was not improved by the routine addition of surgery to radical radiation, although the incidence of serious complications was markedly elevated. The results of treatment of adenocarcinoma of the cervix by radiation therapy alone are not significantly different from those achieved with squamous cell carcinoma. Surgery should be used as a salvage procedure in case of failure, rather than on a routine basis. PMID:1148986

    Primary small intestinal adenocarcinoma is rare and its outcome is poor. A 46-year-old man admitted for vomiting was found in enhanced abdominal CT to have local jejunum stenosis and dilation at its oral site. A partial jejunectomy was performed and a jejunal tumor with multiple disseminated nodules in the peritoneum was revealed. Histologically, the adenocarcinoma of the jejunum appeared to be a papillary adenocarcinoma, and also, in part, a moderately differentiated tubular adenocarcinoma. After the jejunectomy, the patient was treated with S-1 chemotherapy, but 22 months after the initial diagnosis, a recurrence was detected. The patient underwent a second partial jejunectomy, and a weekly dose of paclitaxel (PTX) plus doxifluridine (5'-DFUR) was selected as the second-line treatment. The patient is still responding to the treatment 55 months after the last operation. Combination chemotherapy with weekly PTX/5'-DFUR may improve the prognosis for S-1-resistant small intestinal adenocarcinoma.

    Primary carcinoma of ureter is an uncommon malignancy. Of which, mostly are transitional cell carcinomas followed by squamous cell carcinomas and adenocarcinomas being the rarest histopathology encountered. We report a case of adenocarcinoma ureter in a middle-aged male along with its clinical scenario. A 62-year-old male, presented with complaints of lower urinary tract symptoms. Computerized tomography urogram showed a soft tissue lesion at the right ureterovesical junction. Cystoscopic biopsy reported villous adenoma. Diethylene triamine pentaacetic acid scan reported nonfunctioning right kidney. He underwent laparoscopic right nephroureterectomy, and histopathology reported adenocarcinoma of the right lower third of ureter, with positive distal and close radial margins. The patient received external beam radiation to the postoperative bed and lymph nodes, and he is disease-free till date. PMID:27453661

    Hydatid cyst disease is a zoonotic disease caused by Echinococcus granulosus, E.multilocularis or E.Vogli. The most common primary site is liver (75%) followed by lungs (5-15%) and other organs constitute 10-20%. Peritoneal hydatid cysts are very rare especially primary peritoneal hydatid. Secondary peritoneal hydatid cysts are relatively common, which usually occurs due to rupture of primary hepatic hydatid cyst. We present a rare case of large primary peritoneal hydatid cyst misdiagnosed as torsion of ovarian cyst that underwent Laparotomy with cyst excision and postoperative Albendazole therapy.

    Primary retroperitoneal Müllerian adenocarcinoma (PRMA) is an extremely rare tumor and the cause remains unknown. We report a case of PRMA arising from endometriosis. A 52-year-old woman with a history of malignant lymphoma underwent a follow-up computed tomography scan, which revealed a retroperitoneal tumor. Immunohistochemical analysis of tumor resected during laparoscopic surgery showed adenocarcinoma positive for cytokeratin 7 and negative for cytokeratin 20. The patient had undergone hysterectomy and bilateral salpingo-oophorectomy 14 years ago for myoma uteri and endometrial cysts and was treated with estrogen-replacement therapy. The size of the tumor increased and laparotomy was performed. Histopathological examination showed adenocarcinoma resembling endometrial adenocarcinoma, which stained positive for cancer antigen 125, cancer antigen 19-9, estrogen receptor, and progesterone receptor immunohistochemically. The focus of the endometriosis was found at the edge of the tumor, and the stromal cells around the tumor cells were CD10 positive. The patient was diagnosed as having PRMA arising from endometriosis, and treated with adjuvant chemotherapy.

    The aim of this study was to describe 2 cases of primary peritoneal malignant mixed müllerian tumor (MMMT). Two patients with primary peritoneal MMMT were examined for their clinical and pathologic features. We describe 2 cases of primary peritoneal MMMT in which the carcinomatous and mesenchymal components were readily identifiable, predominantly involving the peritoneum, with no ovarian involvement. The peritoneum and ovaries, with their common embryologic origin, likely account for the peritoneum’s ability to undergo a similar malignant transformation, with the resultant genesis of an MMMT of peritoneal origin.

    Adenocarcinoma with osteoblastic metastases is classically seen in prostate, breast, and lung primaries. Less common primary sites include thyroid, kidney, and stomach. We present two cases of primary gastrointestinal adenocarcinoma with metastatic osteoblastic activity from two previously unreported sites. The first case represents an esophageal adenocarcinoma arising in a background of intestinal metaplasia that metastasized with osteoblastic activity to the deltoid muscle. The second case demonstrates a Stage IV sigmoid colon adenocarcinoma with osteoblastic metastases to the liver and lymph nodes. The findings indicate that metastases from various gastrointestinal primary adenocarcinomas can have prominent bone formation. PMID:27738541

    To compare the growth condition between different sources and different culture environments, mesothelial cells were isolated from omentum and peritoneal dialysate effluent (PDE), seeded at different densities (5 × 10⁵, 1 × 10⁵, 5 × 10⁴, 1 × 10⁴, 5 × 10³, 1 × 10³ and 5 × 10² cells/cm², respectively), supported with different fetal calf serum (FCS) concentrations (3%, 6%, 10% and 15%) and grown in dishes with and without gelatin pre-coating. Growth condition was evaluated by simple morphological observation. Cells phenotype was examined by immunofluorescent staining. The results showed that omentum-derived mesothelial cells generally showed a uniform growth pattern with good quality. Alternatively, there was a wide patient-to-patient variation in PDE-derived culture. Heterogeneous colonies composed of a mixture of large, small or abortive mesothelial colonies as well as fibroblastoid colonies were frequently observed. A minimum seeding density of 5 × 10³ cells/cm² is required for the omentum-derived mesothelial cells to grow to confluent monolayer (1-5 × 10⁴ cells/cm² for initial culture from fresh PDE). Appropriate seeding density is always associated with successful culture in omentumbased culture, but not in PDE-based culture. Mesothelial cells could grow to confluency regardless of FCS concentration and gelatin pre-coating. However, growth rate was slower in lower FCS concentrations and on dishes without gelatin coating. Most cells in culture expressed cytokeratin and vimentin, but not VWF. Alpha-smooth muscle actin frequently appeared in cytokeratin+ mesothelial cells, especially in higher FCS concentrations and in PDE-derived culture. Our data demonstrate that PDE, in contrast to omentum, provides a source of mesothelial cells with poor and unstable quality for primary culture. Healthy cell quality and sufficient seeding density seem to be the most important factors for successful culture of mesothelial cells. The frequent occurrence

    The landscape of genetic alterations in lung adenocarcinoma derived from Asian patients is largely uncharacterized. Here we present an integrated genomic and transcriptomic analysis of 335 primary lung adenocarcinomas and 35 corresponding lymph node metastases from Chinese patients. Altogether 13 significantly mutated genes are identified, including the most commonly mutated gene TP53 and novel mutation targets such as RHPN2, GLI3 and MRC2. TP53 mutations are furthermore significantly enriched in tumours from patients harbouring metastases. Genes regulating cytoskeleton remodelling processes are also frequently altered, especially in metastatic samples, of which the high expression level of IQGAP3 is identified as a marker for poor prognosis. Our study represents the first large-scale sequencing effort on lung adenocarcinoma in Asian patients and provides a comprehensive mutational landscape for both primary and metastatic tumours. This may thus form a basis for personalized medical care and shed light on the molecular pathogenesis of metastatic lung adenocarcinoma. PMID:26647728

    Gastric cancer is one of the most aggressive cancers and is the second leading cause of cancer death worldwide. Approximately 40% of global gastric cancer cases occur in China, with peritoneal metastasis being the prevalent form of recurrence and metastasis in advanced disease. Currently, there are limited clinical approaches for predicting and treatment of peritoneal metastasis, resulting in a 6-month average survival time. By comprehensive genome analysis will uncover the pathogenesis of peritoneal metastasis. Here we describe a comprehensive whole-genome and transcriptome sequencing analysis of one advanced gastric cancer case, including non-cancerous mucosa, primary cancer and matched peritoneal metastatic cancer. The peripheral blood is used as normal control. We identified 27 mutated genes, of which 19 genes are reported in COSMIC database (ZNF208, CRNN, ATXN3, DCTN1, RP1L1, PRB4, PRB1, MUC4, HS6ST3, MUC17, JAM2, ITGAD, IREB2, IQUB, CORO1B, CCDC121, AKAP2, ACAN and ACADL), and eight genes have not previously been described in gastric cancer (CCDC178, ARMC4, TUBB6, PLIN4, PKLR, PDZD2, DMBT1and DAB1).Additionally,GPX4 and MPND in 19q13.3-13.4 region, is characterized as a novel fusion-gene. This study disclosed novel biological markers and tumorigenic pathways that would predict gastric cancer occurring peritoneal metastasis. PMID:26330360

    A 47-year-old woman who presented with abdominal pain was found to have a 20 cm cystic retroperitoneal mass. Pathology indicated a colonic-type adenocarcinoma arising in a primary retroperitoneal mature cystic teratoma. The adenocarcinoma was predominantly intracystic with focal superficial invasion into the cyst wall but not beyond the teratoma capsule. Immunohistochemistry showed that the adenocarcinoma cells were diffusely positive for cytokeratin 20 (CK20) and caudal-type homeobox transcription factor-2 (CDX2) but negative for CK7, confirming the colonic phenotype. In addition, the adenocarcinoma was seen adjacent to teratomatous colonic-type mucosa with adenomatous change (i.e. adenoma), suggesting that it was probably arising from a colonic-type adenoma within the teratoma. The carcinoma had a higher Ki-67 proliferation index and had a higher percentage of cells stained for p53 than the adjacent adenomatous lesion. To the authors' knowledge this is the first documented case in which a colonic-type adenocarcinoma was seen arising from a precursor lesion (i.e. a colonic-type adenoma in a primary retroperitoneal mature cystic teratoma) and is the second case of intestinal-type adenocarcinoma arising in a primary retroperitoneal mature cystic teratoma.

    Cytodiagnosis is a simple, non-invasive and economical screening method for uterine cervical malignancy. Adenocarcinoma as a primary tumor of uterine cervix, although relatively rare, is increasing recently. The first part of the study consisted of 113 patients, seen during a 10-year period, with adenocarcinoma of the uterine cervix proven by tissue diagnosis with prior and/or coincident Papanicolaou smears available in our hospital. Their cytology were as follows: positive/suspicious for adenocarcinoma in 72 cases (63.7%) and incorrect diagnosis for adenocarcinoma in 41 cases (36.3%). These included epidermoid carcinoma, 21 cases (18.6%); atypia, 8 cases (7.1%); negative smears, 8 cases (7.1%); inadequate specimens, 3 cases (2.7%) and radiation effect, 1 case (0.8%). The second part of the study is concerned with the 82 cases whose smear diagnosis was adenocarcinoma in the same period. The results of their tissue diagnosis and accuracy were as follows: adenocarcinoma in 62 cases (75.6%); epidermoid carcinoma in 9 and epidermoid carcinoma in situ in 3 cases totalling 12 cases (14.6%); and false positive in 8 cases (9.8%). The cytomorphology and its correlation to underdiagnosis and overdiagnosis is discussed. Our data revealed that cervicovaginal smears served as a routine for the screening of primary adenocarcinoma of the uterine cervix and for follow-up and detection of recurrence. In order to increase the accuracy, screening cytotechnicians and cytopathologists should acquaint themselves with the morphology of cervical adenocarcinoma by comparing cervicovaginal smear with histopathology.

    Primary peritoneal carcinoma (PPC) is a type of rare malignant epithelial tumor. Metastasis from PPC to breast has been rarely reported. PPC originates de novo from the peritoneal tissues rather than invasion or metastasis from adjacent or remote organs. PPCs have been implicated in many cases of carcinomas of unknown primary origin. It is similar to ovarian cancer (OvCa), because it shares the same common embryonic origin, the coelomic epithelium (mesodermal origin). The mechanism of oncogenesis remains elusive. In this article, we report a rare case of PPC in a patient 10 years after total abdominal hysterectomy and bilateral salpingooophorectomy for uterine leiomyoma, which was widely spread in the abdomen and metastasized to the colon, liver and distant organs including breast. The treatment is similar to that of primary ovarian cancer. We also reviewed the primary peritoneal cancer metastatic to breast and discuss the possible mechanisms and biology of primary peritoneal cancer, using experimental and animal model. PMID:27807506

    Adenocarcinoma is the most common histological type of lung carcinoma. Recently the histologic classification of adenocarcinomas in the lung was modified to better reflect biologic properties and prognosis. We reviewed the histology of all primary lung adenocarcinomas operated on in Iceland during a 20-year period and assessed the impact of histology on survival. This nationwide study included 285 patients (mean age 67 years, 57% female), who underwent resection in Iceland from 1991 to 2010. Tumors were reclassified according to the current IASLC/ATS/ERS classification system. Overall survival was estimated by the Kaplan-Meier method and Cox regression analysis used to evaluate prognostic factors of overall mortality. Acinar predominant adenocarcinoma was the most common histological subtype (46%) followed by solid-predominant (SPA) with mucin production comprised (23%). Non-invasive carcinomas were rare. A difference in survival between the histological adenocarcinoma subtypes was not seen (p = 0.32) and multivariate analysis showed that advanced stage and age predicted worse outcome, but histologic subtyping of adenocarcinoma did not. In this nation-wide study there was not a statistical difference in survival according to adenocarcinoma subtypes and the histological subtype did not predict mortality. Preinvasive and minimally invasive adenocarcinomas were rare.

    Cancer stem cells (CSCs) are unique subpopulations that have the capacity to drive malignant progression with renewal abilities. Recently the role of some of CSCs in gastric adenocarcinoma has been studied. This study was performed in order to evaluate CD44 and CD133 expressions by immunohistochemistry in 95 primary gastric adenocarcinoma and their relation to clinical and pathological parameters of these tumors. There was a significant correlation between CD44 expression and cancer subtype (intestinal), tumor size (4-8 cm), depth of invasion, no lymphatic/vascular invasion and moderate differentiation. There was a significant correlation between CD133 expression and patient's age (> 65 years), cancer subtype (intestinal), tumor size (4-8 cm), depth of invasion and moderate differentiation. CSC markers like CD 44 and CD133 had high expression in primary gastric adenocarcinoma and had some relations to clinical and pathological parameters of tumors. PMID:25635255

    High-grade versions of appendiceal goblet cell carcinoids ('adenocarcinoma ex-goblet cell carcinoids') are poorly characterized. We herein document 77 examples. Tumors occurred predominantly in females (74%), mean age 55 years (29-84), most with disseminated abdominal (77% peritoneal, 58% gynecologic tract involvement) and stage IV (65%) disease. Many presented to gynecologic oncologists, and nine had a working diagnosis of ovarian carcinoma. Metastases to liver (n=3) and lung (n=1) were uncommon and none arose in adenomatous lesions. Tumors had various histologic patterns, in variable combinations, most of which were fairly specific, making them recognizable as appendiceal in origin, even at metastatic sites: I: Ordinary goblet cell carcinoid/crypt pattern (rounded, non-luminal acini with well-oriented goblet cells), in variable amounts in all cases. II: Poorly cohesive goblet cell pattern (diffusely infiltrative cords/single files of signet ring-like/goblet cells). III: Poorly cohesive non-mucinous cell (diffuse-infiltrative growth of non-mucinous cells). IV: Microglandular (rosette-like glandular) pattern without goblet cells. V: Mixed 'other' carcinoma foci (including ordinary intestinal/mucinous). VI: goblet cell carcinoid pattern with high-grade morphology (marked nuclear atypia). VII: Solid sheet-like pattern punctuated by goblet cells/microglandular units. Ordinary nested/trabecular ('carcinoid pattern') was very uncommon. In total, 33(52%) died of disease, with median overall survival 38 months and 5-year survival 32%. On multivariate analysis perineural invasion and younger age (<55) were independently associated with worse outcome while lymph-vascular invasion, stage, and nodal status trended toward, but failed to reach, statistical significance. Worse behavior in younger patients combined with female predilection and ovarian-affinity raise the possibility of hormone-assisted tumor progression. In conclusion, 'adenocarcinoma ex-goblet cell carcinoid' is

    Fetal lung adenocarcinoma (FLAC) is a rare variant of lung adenocarcinoma. Studies regarding FLAC have been based only on histopathological observations, thus representative in vitro models of FLAC cultures are unavailable. We have established and characterized a human primary FLAC cell culture, exploring its biology, chemosensitivity, and migration. FLAC cells and specimen showed significant upregulation of VEGF165 and HIF-1α mRNA levels. This observation was confirmed by in vitro chemosensitivity and migration assay, showing that only Axitinib was comparable to Cisplatin treatment. We provide a suitable in vitro model to further investigate the nature of this rare type of cancer. PMID:24380379

    Abstract Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor in gastrointestinal tracts; however, the synchronous or metachronous coexistence of GIST with additional primary malignancy is not common. Here, we present an unusual case of gastric GIST with metachronous primary lung adenocarcinoma diagnosed during his adjuvant treatment with oral receptor tyrosine kinase inhibitor imatinib mesylate (400 mg daily). After 6-month use of imatinib, the patient suffered from dry cough and dyspnea. Subsequent lung biopsy demonstrated adenocarcinoma with diffuse interstitial changes. Our research emphasizes the possibility of an additional primary tumor with GIST, and reminds the clinicians to strengthen the surveillance of the additional cancer during the follow-up of GIST patients.

    Primary adenocarcinoma of the seminal vesicles (SV) are extremely rare and approximately only 60 cases have been reported in the literature. Due to the lack of specific symptoms the patients often present in an advanced stage of their disease. The only clinical examination that can indicate the presence of a neoplasm in the SVs is the digital rectal examination (DRE). Serum prostatic specific antigen (PSA) and prostate specific acid phosphatase (PAP) are usually normal in patients with primary adenocarcinoma of the SV and only CA-125 can be proved a useful blood biomarker contributing to the diagnosis and the follow up of the SV adenocarcinoma. Computed tomography (CT) and magnetic resonance imaging (MRI) and FDG-PET/CT have been used for the diagnosis and the staging of the SV adenocarcinoma. Various combinations of radical surgery, radiotherapy androgen deprivation therapy and chemotherapy have been proposed for the management of the disease but the prognosis is poor and the mean survival is two years after the diagnosis.

The video-assisted thoracic surgery right lower lobectomy with systematic lymph node dissection was performed first, followed by myxoma excision by port access surgery through the same working port incision. The histopathologic analysis confirmed a pT2a N0 M0 R0 (TNM 7th edition) primary poorly differentiated pulmonary adenocarcinoma and a completely excised cardiac myxoma. Postoperative recovery was uneventful, and follow-up at 6 weeks confirmed an excellent surgical and oncologic outcome.

    Isolated pancreatic tuberculosis (TB) is considered an extremely rare condition, even in the developing countries. Most reported cases of pancreatic TB are diagnosed after exploratory laparotomy or autopsy. Pancreatic TB is a potential mimic of invasive pancreatic malignancy and the presence of vascular invasion does not distinguish one condition from the other. Every effort should be made for the earliest diagnosis of this condition as TB is a treatable condition and it avoids unnecessary management of pancreatic carcinoma. Here we report a rare case of primary pancreatic head TB in a 58-year-old male who presented with hypodense lesion in head of pancreas with double duct sign and portal vein invasion mimicking non-resectable pancreatic carcinoma.

Clinical examination and computed tomography demonstrated a soft-tissue mass located at the base of the penis without signs of other primary tumours or metastasis. Clinicopathological findings revealed paraneoplastic hypercalcaemia. Fine-needle aspiration cytology of the mass suggested an epithelial tumour with several criteria of malignancy present. Following surgical excision of the mass, the hypercalcaemia resolved. Histopathology and immunohistochemistry revealed features consistent with an adenocarcinoma. Despite thorough examination, no perineal or anal sac tumour was found. To the authors' knowledge, this is the first reported case of a penile adenocarcinoma with hypercalcaemia of malignancy.

    The incidence of synchronous lung tumors is rare, as reported in various clinical series, ranging from 0.2% to 8%. Most reported cases of synchronous tumors were shown to have the same histologic types of lung cancer. Among possible combinations, squamous cell carcinoma was by far the most common. Primary pulmonary lymphoma (PPL) is very rare in clinics accounting for only 0.5-1% of primary lung tumors. There is no report about synchronous primary pulmonary adenocarcinoma presenting with lung lymphoma. It can be easily misdiagnosed or missed. Although the treatment of PPL and synchronous pulmonary tumors has controversial, surgery with/without postoperative adjuvant radio-chemotherapy are used for most patients in present. We describe a case of synchronous primary lung tumors presenting with lymphoma and adenocarcinoma, in which expression of the cell surface antigens were evaluated immunohistochemically. By taking into consideration of the reported experiences, the author discusses the clinical features, prognostic criteria and therapeutic management of synchronous lung cancer and PPL. PMID:26548938

    Primary epithelial tumor of the renal pelvis is rare and only 100 cases are reported in the literature [1]. Histological examination of the tumor showed glands, cysts, and papillae lined by pseudostratified columnar epithelium with hyperchromatic nuclei. Scattered signet ring-type cells were also seen floating in large pools of extracellular mucin. Sections from the ureter showed a component of adenocarcinoma in situ. No invasive tumor was identified in ureteric tissue. One case was reported with carcinoma in situ of the ureter (2). Immunohistochemically: The tumor showed positivity for CK7, CK20, CK8/18, GATA-3, MSH-2, MSH-6, MLH-1, Ber-EP4, and S-100-P with focal positivity for CDX-2, weak positivity for PMS-2 and negativity in TTF-1 and Her-2. Molecular pathological analysis revealed microsatellite stability and without mutation in K-ras-gene. Thus, a diagnosis of mucinous adenocarcinoma of the renal pelvis with in situ adenocarcinoma of the ureter was made. PMID:24565683

    Cerumenal adenocarcinoma is a rare neoplasm arising from the modified sweat glands of the ear. Before the diagnosis of primary tumour is made, a thorough search must be undertaken to exclude the possibility of metastatic disease, which occurs more commonly. Benign adenoma can also occur and this may be identical histologically to the malignant variety. The presence of local invasiveness may be the only differentiating feature. Aggressive local resection followed by postoperative radiotherapy form the cornerstone of management. Individuals treated with radiotherapy alone have a life expectancy of less than 12 months whereas cures have been reported with radical surgery.

    Ga-prostate-specific membrane antigen (PSMA) PET/CT is increasingly used to evaluate recurrent prostatic malignancy due to its high specificity. A 56-year-old man with previous history of treated prostate cancer 4 years earlier presented with rising prostate-specific antigen level and underwent Ga-PSMA PET/CT, which demonstrated an enlarging pulmonary nodule without PSMA avidity. The pulmonary nodule, however, showed moderate uptake on a corresponding FDG PET/CT study, suspicious of primary lung malignancy. Cytological and histopathological examination of the pulmonary nodule confirmed a metastatic deposit from ductal prostatic adenocarcinoma, an uncommon variant of prostatic malignancy.

    Umbilical metastasis (Sister Mary Joseph's nodule) is often the first sign of intraabdominal and/or pelvic carcinoma. We describe the fourth case reported in the literature of Sister Mary Joseph's nodule originating from fallopian tube carcinoma. In a 54-year-old woman, Sister Mary Joseph's nodule was unexpectedly detected during umbilical hernia repair. Subsequent laparoscopy revealed a 2-cm friable tumor located at the fimbriated end of right fallopian tube and 1-cm peritoneal implant in the pouch of Douglas. Laparoscopic bilateral adnexectomy and resection of the peritoneal implant were performed. Because frozen section examination revealed fallopian tube carcinoma, the procedure was continued with laparotomy including total abdominal hysterectomy, omentectomy, and pelvic lymph node sampling. Final diagnosis was stage IIIB fallopian tube carcinoma. The patient received postoperative adjuvant chemotherapy with single-agent carboplatin and has remained alive and with no evidence of disease. It is concluded that in cases of Sister Mary Joseph's nodule, laparoscopy can be a useful tool in the search of the primary tumor in the abdomen and/or pelvis. Laparoscopy can provide crucial information with respect to the location, size, and feasibility of optimal surgical resection of the intraabdominal and/or pelvic tumors.

    Introduction We report a case of primary adenocarcinoma in the third portion of the duodenum (D3) curatively resected by laparoscopic and endoscopic cooperating surgery (LECS). Presentation of case A 65-year-old woman had a routine visit to our hospital for a follow-up of rectal cancer resected curatively 2 years ago. A routine screening gastroduodenal endoscopy revealed an elevated lesion of 20 mm in diameter in the D3. The preoperative diagnosis was adenoma with high-grade dysplasia; however, suspicion about potential adenocarcinoma was undeniable. Curative resection was performed by LECS. Pathological examination revealed intramucosal adenocarcinoma arising from normal duodenal mucosa. The tumor was stage I (T1/N0/M0) in terms of the tumor, nodes, metastasis (TNM) classification. LECS for duodenal tumor has seldom been reported previously, and this is the first report of LECS for primary adenocarcinoma in the D3. The transverse mesocolon was removed from the head of pancreas to expose the duodenum, and the accessory right colic vein was cut; this was followed by the Kocher maneuver for mobilization of the lesion site. Discussion LECS enabled en bloc resection with adequate surgical margins and secure intra-abdominal suturing. Thorough mobilization of the mesocolon and pancreas head is essential for this procedure because it facilitates correct resection and suturing. Conclusion LECS is a feasible treatment option for duodenal neoplasms, including intramucosal adenocarcinoma, even though it exists in the D3. PMID:25723745

    BACKGROUND: Endoscopic ultrasound (EUS) with fine-needle aspiration (FNA) is often used to assist in the evaluation of pancreatic lesions and may help to diagnose benign versus malignant neoplasms. However, there is a paucity of literature regarding comparative EUS characteristics of various malignant pancreatic neoplasms (primary and metastatic). OBJECTIVE: To compare and characterize primary pancreatic adenocarcinoma versus other malignant neoplasms, hereafter referred to as nonprimary pancreatic adenocarcinoma (NPPA), diagnosed by EUS-guided FNA. METHODS: The present study was a retrospective analysis of a prospectively maintained database. The setting was a tertiary care, academic medical centre. Patients referred for suspected pancreatic neoplasms were evaluated. Based on EUS-FNA characteristics, primary pancreatic adenocarcinoma was differentiated from other malignant neoplasms. The subset of other neoplasms was defined as malignant lesions that were ‘NPPAs’ (ie, predominantly solid or solid/cystic based on EUS appearance and primary malignant lesions or metastatic lesions to the pancreas). Pancreatic masses that were benign cystic lesions (pseudocyst, simple cyst, serous cystadenoma) and focal inflammatory lesions (acute, chronic and autoimmune pancreatitis) were excluded. RESULTS: A total of 230 patients were evaluated using EUS-FNA for suspected pancreatic mass lesions. Thirty-eight patients were excluded because they were diagnosed with inflammatory lesions or had purely benign cysts. One hundred ninety-two patients had confirmed malignant pancreatic neoplasms (ie, pancreatic adenocarcinoma [n=144], NPPA [n=48]). When comparing adenocarcinoma with NPPA lesions, there was no significant difference in mean age (P=0.0675), sex (P=0.3595) or average lesion size (P=0.3801). On average, four FNA passes were necessary to establish a cytological diagnosis in both lesion subtypes (P=0.396). Adenocarcinomas were more likely to be located in the pancreatic head

    Primary biliary cholangitis (PBC) is a chronic autoimmune liver disease with progressive cholestasis and liver fibrosis. Similar to human patients with PBC, p40−/−IL-2Rα−/− mice spontaneously develop severe autoimmune cholangitis. Although there has been considerable work on immune regulation and autoimmunity, there is a relative paucity of work directed at the functional implications of the key peritoneal cavity (PC) B cell subset, coined B1a cells in PBC. We used flow cytometry and high-resolution microarrays to study the qualitative and quantitative characteristics of B cells, particularly B1a cells, in the PC of p40−/−IL-2Rα−/− mice compared to controls. Importantly, B1a cell proliferation was markedly lower as the expression of Ki67 decreased. Meanwhile, the apoptosis level was much higher. These lead to a reduction of B1a cells in the PC of p40−/−IL-2Rα−/− mice compared to controls. In contrast, there was a dramatic increase of CD4+ and CD8+ T cells accompanied by elevated production of IFN-γ. In addition, we found a negative correlation between the frequency of B1a cells and the presence of autoreactive CD8+ T cells in both liver and PC of p40−/−IL-2Rα−/− mice. From a functional perspective, B cells from p40−/−IL-2Rα−/− mice downregulated IL-10 production and CTLA-4 expression, leading to loss of B cell regulatory function. We suggest that the dysfunction of B1a cells in the PC in this murine model of autoimmune cholangitis results in defective regulatory function. This highlights a new potential therapeutic target in PBC. PMID:27105495

    Regulatory enhancer elements in solid tumours remain poorly characterized. Here we apply micro-scale chromatin profiling to survey the distal enhancer landscape of primary gastric adenocarcinoma (GC), a leading cause of global cancer mortality. Integrating 110 epigenomic profiles from primary GCs, normal gastric tissues and cell lines, we highlight 36,973 predicted enhancers and 3,759 predicted super-enhancers respectively. Cell-line-defined super-enhancers can be subclassified by their somatic alteration status into somatic gain, loss and unaltered categories, each displaying distinct epigenetic, transcriptional and pathway enrichments. Somatic gain super-enhancers are associated with complex chromatin interaction profiles, expression patterns correlated with patient outcome and dense co-occupancy of the transcription factors CDX2 and HNF4α. Somatic super-enhancers are also enriched in genetic risk SNPs associated with cancer predisposition. Our results reveal a genome-wide reprogramming of the GC enhancer and super-enhancer landscape during tumorigenesis, contributing to dysregulated local and regional cancer gene expression.

    We analyzed the interactions between human primary cells from pancreatic ductal adenocarcinoma (PDAC) and polymeric scaffolds to develop 3D cancer models useful for mimicking the biology of this tumor. Three scaffold types based on two biocompatible polymeric formulations, such as poly(vinyl alcohol)/gelatin (PVA/G) mixture and poly(ethylene oxide terephthalate)/poly(butylene terephthalate) (PEOT/PBT) copolymer, were obtained via different techniques, namely, emulsion and freeze-drying, compression molding followed by salt leaching, and electrospinning. In this way, primary PDAC cells interfaced with different pore topographies, such as sponge-like pores of different shape and size or nanofiber interspaces. The aim of this study was to investigate the influence played by the scaffold architecture over cancerous cell growth and function. In all scaffolds, primary PDAC cells showed good viability and synthesized tumor-specific metalloproteinases (MMPs) such as MMP-2, and MMP-9. However, only sponge-like pores, obtained via emulsion-based and salt leaching-based techniques allowed for an organized cellular aggregation very similar to the native PDAC morphological structure. Differently, these cell clusters were not observed on PEOT/PBT electrospun scaffolds. MMP-2 and MMP-9, as active enzymes, resulted to be increased in PVA/G and PEOT/PBT sponges, respectively. These findings suggested that spongy scaffolds supported the generation of pancreatic tumor models with enhanced aggressiveness. In conclusion, primary PDAC cells showed diverse behaviors while interacting with different scaffold types that can be potentially exploited to create stage-specific pancreatic cancer models likely to provide new knowledge on the modulation and drug susceptibility of MMPs.

    Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor in gastrointestinal tracts; however, the synchronous or metachronous coexistence of GIST with additional primary malignancy is not common.Here, we present an unusual case of gastric GIST with metachronous primary lung adenocarcinoma diagnosed during his adjuvant treatment with oral receptor tyrosine kinase inhibitor imatinib mesylate (400 mg daily). After 6-month use of imatinib, the patient suffered from dry cough and dyspnea. Subsequent lung biopsy demonstrated adenocarcinoma with diffuse interstitial changes.Our research emphasizes the possibility of an additional primary tumor with GIST, and reminds the clinicians to strengthen the surveillance of the additional cancer during the follow-up of GIST patients.

    Severe immunodeficient mice have become invaluable tools in human stem cell and tumor research. In this study, we compared the phagocytic activity of peritoneal macrophages against primary effusion lymphoma (PEL) among Rag-2/Jak3 double-deficient (Rag-2(-/-)Jak3(-/-)) mice with NOD and non-NOD (Balb/c and C57/BL6). We also evaluated lymphomatous effusion and infiltration in a PEL xenograft mouse model using these severe immunodeficient mice. In the phagocytic assay, peritoneal macrophages in the NOD background phagocytosed CFSE-labeled BCBL-1, a PEL cell line, less efficiently than those in the non-NOD background. BCBL-1 cells were successfully engrafted into both the NOD background and non-NOD background; however, the volume of ascites of the NOD background was significantly higher than that of the non-NOD background. Moreover, the organ invasion of PEL cells was suppressed in non-NOD background mice. Thus, the NOD genetic background is considered to contribute to more lymphomatous effusion and the infiltration of PEL cells than a non-NOD background. Our results showed that the NOD background allowed more lymphomatous effusion and infiltration than other backgrounds and peritoneal macrophages played a critical role in preventing the growth and infiltration of PEL cells.

    Paclitaxel and carboplatin upregulate thymidine phosphorylase and thus may provide synergistic antitumor activity in combination with capecitabine (CTX). We, therefore, performed a phase I/II study of CTX. In the phase I study, patients with advanced solid tumors received carboplatin on day 1, paclitaxel on days 1, 8, 15 and capecitabine orally twice a day on days 8-21, every 4 weeks. Phase II patients with advanced adenocarcinoma of unknown primary (ACUP) were treated at the maximal tolerable dose. The phase I study enrolled 29 patients evaluable for dose limiting toxicity. The recommended phase II dose was capecitabine 750 mg/m(2) bid, paclitaxel 60 mg/m(2)/week and carboplatin AUC of 6. There were 9 confirmed responses, 5 partial responses and disease stabilization >3 months in 14 patients. The phase II study was prematurely terminated at 25 patients due to cessation of funding. The objective response rate was 32 % (95 % CI 0.15-0.54), the median progression-free survival 5.5 months (95 % CI 2.8-10.8 months) and the median overall survival 10.8 months (95 % CI 6.0-32.0 months). CTX demonstrated acceptable tolerability and antitumor activity. At the recommended dose level in patients with ACUP, this regimen showed encouraging preliminary activity.

    Mutations on epidermal growth factor receptor (EGFR) of adenocarcinomas of lung have been found to be associated with increased sensitivity to EGFR tyrosine kinase inhibitors and K-ras mutations may correlate with primary resistance. We aimed to explore the discordant mutation statuses of EGFR and K-ras between primary tumors and matched brain metastases in adenocarcinomas of lung. We used a sensitive Scorpion ARMS method to analyze EGFR mutation, and Sanger sequencing followed by allele-specific real-time polymerase chain reaction to analyze K-ras mutation. Forty-nine paired tissues with both primary adenocarcinoma of lung and matched brain metastasis were collected. Thirteen patients (26.5%) were discordant for the status of EGFR between primary and metastatic sites. K-ras gene could be checked in paired specimens from 33 patients, thirteen patients (39.6%) were discordant for the status of K-ras. In primary lung adenocarcinoma, there were 14 patients of mutant EGFR had mutant K-ras synchronously. This study revealed that the status of EGFR mutation in lung adenocarcinomas is relatively consistent between primary and metastatic sites compared to K-ras mutation. However, there are still a few cases of adenocarcinoma of lung showing discordance for the status of EGFR mutation. Repeated analysis of EGFR mutation is highly recommended if tissue from metastatic or recurrent site is available for the evaluation of target therapy. PMID:27070580

    A 20-year-old African American male presented with a history of left flank pain and passing of light pink urine. Medical history included sickle cell trait. Urine analysis was positive for protein and blood. Metabolic profile, autoantibody screen, and complement levels were normal. Hemoglobin electrophoresis revealed an 41.8% HbS diagnostic of sickle cell trait. Creatinine clearance was normal and proteinuria was nonnephrotic. A noncontrast computed tomography (CT) scan showed left proximal hydronephrosis. Urology follow-up was arranged and the differential included renal papillary necrosis, or renal cyst rupture. He presented 3 months later with sudden onset left flank pain and gross hematuria. Serum creatinine was 1.8 mg/dL. Computed tomography scan with contrast revealed innumerable lung lesions, an enlarged heterogenously enhancing left kidney, and retroperitoneal adenopathy. Ultrasound revealed an obstructed left collecting system and a 14-cm enlarged left kidney with no discrete mass. Testicular markers/ultrasound, upper/lower endoscopies were normal. Lung biopsy revealed poorly differentiated adenocarcinoma positive for cytokeratin 7. Renal, sarcoma, and gastrointestinal markers were negative. By exclusion, it appeared that the patient had a carcinoma of unknown primary. However, with the clinical and personal history, a diagnosis of renal medullary carcinoma (RMC) was made. RMC is a rare and highly malignant tumor that should always be included in the differential of a patient with sickle cell disorder and hematuria. Renal biopsy typically fails to sample the renal medulla and radiologic findings might not raise the suspicion of a renal tumor. Thus, clinical suspicion must always be high in order to preserve the patient's only chance of prolonged survival.

    Summary We present a case of a 45-year-old woman with a long-standing history of persistent cervical dysplasia that resulted in a hysterectomy. Subsequent vaginal smears revealed high-grade vaginal intraepithelial neoplasia (VAIN III) on Pap smear with positive human papilloma virus (HPV) testing. Over the course of 2 years, the patient underwent 2 CO2 laser vaporization procedures of the upper vagina and intermittent 5-fluorouracil therapy. A biopsy performed at the time of the second laser procedure revealed endocervical-type well-differentiated adenocarcinoma, associated with VAIN III. HPV in situ hybridization for HPV types 16 and 18 was positive in both the glandular and squamous mucosa. The patient has no known history of intrauterine diethylstilbestrol exposure or mullerian developmental abnormalities. Subsequently, the patient underwent a radical upper vaginetcomy with bilateral pelvic lymph nodes dissection and bilateral salpingo-oophorectomy. The vaginectomy specimen showed residual adenocarcinoma associated with VAIN-III and extensive vaginal adenosis with free resection margins. This is the second reported case in the literature of adenocarcinoma arising in vaginal adenosis after 5-fluorouracil. Herein, we highlight these important findings and shed some light on the pathogenesis of vaginal adenosis and the subsequent development of vaginal adenocarcinoma. PMID:20173507

    A 38-year-old female presented with a lower abdominal mass. During the operation the mass was found to be retroperitoneal and was excised. Gross examination revealed a mucin-containing cystic lesion with a mural nodule. On microscopic examination, the cystic areas were lined by an invasive mucinous adenocarcinoma and the nodule was composed of an anaplastic sarcomatoid tumor that was immunoreactive for cytokeratin. This present case is the 21st example of a retroperitoneal primary mucinous cystadenocarcinoma and the fourth with a mural nodule. Three of four cases with a mural nodule, including our case, had a rapidly fatal outcome.

    We herein report the immunostimulatory effect of spinach aqueous extract (SAE) on mouse macrophage-like J774.1 cells and mouse primary peritoneal macrophages. SAE significantly enhanced the production of interleukin (IL)-6 and tumor necrosis factor-α by both J774.1 cells and peritoneal macrophages by enhancing the expression levels of these cytokine genes. In addition, the phagocytosis activity of J774.1 cells was facilitated by SAE. Immunoblot analysis revealed that SAE activates mitogen-activated protein kinase and nuclear factor-κB cascades. It was found that SAE activates macrophages through not only TLR4, but also other receptors. The production of IL-6 was significantly enhanced by peritoneal macrophages from SAE-administered BALB/c mice, suggesting that SAE has a potential to stimulate macrophage activity in vivo. Taken together, these data indicate that SAE would be a beneficial functional food with immunostimulatory effects on macrophages.

    The prognosis of seminal vesicle (SV) adenocarcinoma is often poor due to delayed diagnosis. About 95% of the patients die in less than 3 years. Diagnosis is difficult due to the absence of early clinical signs as hematuria, hematospermia and/or dysuria. We present the case of a 61-year-old Caucasian man with a left SV mass detected by transrectal ultrasound. SV ultrasound-guided biopsy showed an adenocarcinoma. The tumor was uniformly strongly immunoreactive for cytokeratin-7 and carcinoembryonic antigen. There was no immunoreactivity for prostate-specific acid phosphatase (PSAP) and CK-20. These tumors have been reported to be also positive for CA-125. Therefore a combination of positive staining for CK-7, CEA and CA-125; with negative staining for CK-20, PSA and PSAP is the pattern of immunohistochemical findings noted for this rare tumor. The computed tomography of the abdomen-pelvis and chest X-ray was negative for metastases. The patient underwent a radical prostatectomy and lymphadenectomy. The prostate, rectum, bladder and lymph nodes were free from tumor involvement. The patient did not receive any adjuvant chemotherapy or radiation; and remains free of disease 3 years post-surgery.

    K-ras mutations promote angiogenesis in lung cancer and contribute to the drug resistance of cancer cells. It is not clear whether K-ras mutated adenocarcinomas are sensitive to anti-angiogenic therapy with monoclonal antibodies (mAbs) that target vascular endothelial growth factor (VEGF). Anti-angiogenic mAbs are usually delivered systemically, but only a small proportion reaches the lung after intravenous injection. We investigated the relevance of a non-invasive pulmonary route for the delivery of anti-VEGF mAbs in the mouse K-ras(LA1) model. We found that pulmonary delivery of these mAbs significantly reduced the number of tumor lesions and inhibited malignant progression. The antitumor effect involves the VEGFR2-dependent inhibition of blood vessel growth, which impairs tumor proliferation. Pharmacokinetic analysis of aerosolized anti-VEGF showed its low rate of passage into the bloodstream, suggesting that this delivery route is associated with reduced systemic side effects. Our findings highlight the value of the aerosol route for administration of anti-angiogenic mAbs in pulmonary adenocarcinoma with K-ras activating-mutations. PMID:25484066

    Mutation of the epidermal growth factor receptor gene (EGFR mutation) is a very important marker in the treatment for non-small cell lung cancer. Since signaling from this receptor induces tumor-associated angiogenesis, we hypothesized that lung cancers with EGFR mutations tend to develop locally with increased angiogenesis. Thus, the association between vascular-poor area of primary tumors and EGFR status was retrospectively investigated in advanced lung adenocarcinomas. To assess vascular-poor area, contrast-enhanced computed tomography scans taken before initial treatment for lung cancer were analyzed, together with primary tumor location (peripheral or central) and size. We analyzed 178 patients with advanced lung adenocarcinoma. EGFR mutations were detected in 95 of the 178 patients (53.4 %). EGFR mutation was found to be significantly related to women (P = 0.0070), never-smokers (P < 0.0001), and tumors without vascular-poor area (P < 0.0001). Based on a multivariate analysis, presence of EGFR mutations was independently associated with never-smokers (P = 0.0046), lack of vascular-poor area (P = 0.0001), and tumor size >30 mm (P = 0.0080). EGFR mutations were found in 41 of 51 never-smokers without vascular-poor area (80.4 %), 19 of 36 never-smokers with vascular-poor area (52.8 %), 19 of 37 current or former-smokers without vascular-poor area (51.4 %), and 16 of 54 current or former-smokers with vascular-poor area (29.6 %). This study showed an association between vascular-poor area of primary tumors and EGFR status. As a consequence, evaluation using a combination of smoking status and vascular-poor area allows us to predict presence of EGFR mutations at a high frequency.

    Traditionally, epithelial ovarian, tubal, and peritoneal cancers have been viewed as separate entities with disparate origins, pathogenesis, clinical features, and outcomes. Additionally, previous classification systems for ovarian cancer have proposed two primary histologic groups that encompass the standard histologic subtypes. Recent data suggest that these groupings no longer accurately reflect our knowledge surrounding these cancers. In this review, we propose that epithelial ovarian, tubal, and peritoneal carcinomas represent a spectrum of disease that originates in the Mullerian compartment. We will discuss the incidence, classification, origin, molecular determinants, and pathologic analysis of these cancers that support the conclusion they should be collectively referred to as adenocarcinomas of Mullerian origin. As our understanding of the molecular and pathologic profiling of adenocarcinomas of Mullerian origin advances, we anticipate treatment paradigms will shift towards genomic driven therapeutic interventions.

    Background Resection of certain recurrent malignancies can prolong survival, but resection of recurrent pancreatic ductal adenocarcinoma is typically contraindicated because of poor outcomes. Methods All patients from 1992 to 2010 with recurrent pancreatic cancer after intended surgical cure were retrospectively evaluated. Clinicopathologic features were compared from patients who did and did not undergo subsequent reoperation with curative intent to identify factors associated with prolonged survival. Results Twenty-one of 426 patients (5 %) with recurrent pancreatic cancer underwent potentially curative reoperation for solitary local-regional (n=7) or distant (n=14) recurrence. The median disease-free interval after initial resection among reoperative patients was longer for those with lung or local-regional recurrence (52.4 and 41.1 months, respectively) than for those with liver recurrence (7.6 months, p=0.006). The median interval between reoperation and second recurrence was longer in patients with lung recurrence (median not reached) than with liver or local-regional recurrence (6 and 9 months, respectively, p=0.023). Reoperative patients with an initial disease-free interval >20 months had a longer median survival than those who did not (92.3 versus 31.3 months, respectively; p=0.033). Conclusion Patients with a solitary pulmonary recurrence of pancreatic cancer after a prolonged disease-free interval should be considered for reoperation, as they are more likely to benefit from resection versus other sites of solitary recurrence.

    Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, with a poor response to chemotherapy and low survival rate. This unfavorable treatment response is likely to derive from both late diagnosis and from complex, incompletely understood biology, and heterogeneity among NSCLC subtypes. To define the relative contributions of major cellular pathways to the biogenesis of NSCLC and highlight major differences between NSCLC subtypes, we studied the molecular signatures of lung adenocarcinoma (ADC) and squamous cell carcinoma (SCC), based on analysis of gene expression and comparison of tumor samples with normal lung tissue. Our results suggest the existence of specific molecular networks and subtype-specific differences between lung ADC and SCC subtypes, mostly found in cell cycle, DNA repair, and metabolic pathways. However, we also observed similarities across major gene interaction networks and pathways in ADC and SCC. These data provide a new insight into the biology of ADC and SCC and can be used to explore novel therapeutic interventions in lung cancer chemoprevention and treatment. PMID:22206048

    Recent clinical trials have revealed that accurate histologic typing of non-small cell lung cancer is essential. Until now, squamous cell carcinoma (SQC) and adenocarcinoma (ADC) markers have not been thoroughly analyzed for pulmonary neuroendocrine carcinomas (NECs). We analyzed the expression of 8 markers [p63, cytokeratin (CK) 5/6, SOX2, CK7, desmocollin 3, thyroid transcription factor-1 (8G7G3/1 and SPT24), and napsin A] in 224 NECs. SOX2 (76.2%) had the greatest expression for NECs. CK5/6 (1.4%), desmocollin 3 (0.5%), and napsin A (0%) were expressed less or not at all in NECs. Although our investigated markers have been reported useful for differentiating between SQC and ADC, some of them were also present in a portion of pulmonary NECs. In our study, CK5/6 and desmocollin 3 were highly specific markers for SQC, and napsin A was highly specific for ADC. These markers are recommended for diagnosis of poorly differentiated non-small cell lung cancer.

    An 82-year-old male was hospitalized with rectal carcinoma that was confirmed endoscopically. Surgical resection of the rectum was performed. Intraoperative examination showed a solitary hepatic metastasis; metastasectomy was also performed. Histological examination of the surgical specimen showed mainly a trabecular arrangement of the tumor cells, alternating with tubuloglandular areas, the tumor being diagnosed in stage IV. The high-power-view examination showed that the tumor cells presented clear cytoplasm, and were diffusely marked by AE1/AE3 keratin, carcinoembryonic antigen (CEA), and CD10. A focal immunostain was also observed for keratins 7/20, vascular endothelial growth factor (VEGF), and its receptor (VEGF-R2). The tumor was proved to be microsatellite stable, presenting K-ras mutation. Based on the immunoprofile and computer scanning, metastases from clear cell renal cell carcinoma and adrenocortical carcinoma have been excluded. Based on these characteristics and the tumor stage, the final diagnosis was primary clear cell adenocarcinoma (CCA). Bevacizumab-based antiangiogenic therapy was indicated. This is the 12th primary CCA of the colorectum ever reported, and the first from Eastern Europe. PMID:25178336

    Background Peritoneal dialysis-related peritonitis is an important negative risk of peritoneal dialysis. Peritonitis results when organisms enter the normally sterile peritoneal space, and the peritoneal immune system is unable to prevent the proliferation of the organisms. Methods The process of reducing the rate of peritonitis includes identification of the need for reducing peritonitis, identification of the cause of the high peritonitis rate through root cause analysis, and intervention. Results Interventions vary depending upon the type of organism causing peritonitis. Nonenterococcal gram-positive peritonitis and Pseudomonas peritonitis are related to contamination and are potentially preventable; enteric peritonitis is difficult to prevent. Conclusion The rate of peritonitis can be reduced through a strong continuous quality improvement team because the majority of peritonitis episodes can be prevented. PMID:25249805

    Intestinal epithelial cells possess apical-basal polarity, which governs the exchange of nutrients and waste. Perturbation of cell polarity appears to be a general feature of cancers, although most colorectal cancers are differentiated adenocarcinomas, in which polarity is maintained to some extent. Little is known about the role of dysregulated polarity in cancer. The cancer tissue-originated spheroid method was applied to the preparation and culture of spheroids. Spheroids were cultured in suspension or in type I collagen gel. Polarity was assessed by IHC of apical markers and electron microscopy. Two types of polarity status in spheroids were observed: apical-in, with apical membrane located at cavities inside the spheroids in type I collagen gel; and apical-out, with apical membrane located at the outermost layer of spheroids in suspension. These polarities were highly interchangeable. Inhibitors of Src and dynamin attenuated the polarity switch. In patients, clusters of cancer cells that invaded vessels had both apical-in and apical-out morphologic features, whereas primary and metastatic tumors had apical-in features. In a mouse liver metastasis model, apical-out spheroids injected into the portal vein became apical-in spheroids in the liver within a few days. Inhibitors of Src and dynamin significantly decreased liver metastasis. Polarity switching was observed in spheroids and human cancer. The polarity switch was critical in an experimental liver metastasis model.

    Rearrangements of the anaplastic lymphoma kinase (ALK) gene are present in 3% to 7% of non-small-cell lung cancers (NSCLCs). Patients harboring ALK rearrangements show very favourable outcomes if treated with targeted agents, among which crizotinib is the first and best studied. Crizotinib, an oral small-molecule tyrosine kinase inhibitor of ALK, MET, and ROS1 kinases, is a very active and well tolerated drug. Nevertheless, the optimal therapy management with this new drug is still partially unknown, especially with regard to the safety of combined treatments. Recently, the integration of locoregional treatments has been proposed as a feasible multimodality strategy in selected patients with good clinical conditions and slow-growing or oligoprogressive disease. In this report, a case of advanced lung adenocarcinoma, progressed after first line chemotherapy and re-biopsied detecting ALK rearrangement, is described. During crizotinib treatment the primary lung tumor showed an excellent regression; meanwhile a major surgery for a metachronous uterine cancer was safely and successfully carried out. PMID:26958511

    Primary mucinous adenocarcinoma of the renal pelvis is easily misdiagnosed and it was rarely reported in the literature. We describe in this study a case of 40-year-old male patient presented with right lumbar pain of one year duration and elevated level of carcinoembryonic antigen (CEA). After a series of imaging examinations, the initial impression was a cystic renal cell carcinoma. Right radical nephrectomy was performed on the patient. The postoperative pathological examination indicated a primary mucinous adenocarcinoma of enteric type of the renal pelvis. After surgical removal of the tumor, an immunotherapy was administrated to prevent recurrence. The patient survives upon this report. A review of pertinent literature is also presented.

    A ‘shotgun’ lipidomics strategy consisting of sequential functional group selective chemical modification reactions coupled with high-resolution / accurate mass spectrometry and ‘targeted’ tandem mass spectrometry (MS/MS) analysis has been developed and applied toward the comprehensive identification, characterization and quantitative analysis of changes in relative abundances of >600 individual glycerophospholipid, glycerolipid, sphingolipid and sterol lipids between a primary colorectal cancer (CRC) cell line, SW480, and its isogenic lymph node metastasized derivative, SW620. Selective chemical derivatization of glycerophosphoethanolamine and glycerophosphoserine lipids using a ‘fixed charge’ sulfonium ion containing, d6-S,S′-dimethylthiobutanoylhydroxysuccinimide ester (d6-DMBNHS) reagent was used to eliminate the possibility of isobaric mass overlap of these species with the precursor ions of all other lipids in the crude extracts, thereby enabling their unambiguous assignment, while subsequent selective mild acid hydrolysis of plasmenyl (vinyl-ether) containing lipids using formic acid enabled these species to be readily differentiated from isobaric mass plasmanyl (alkyl-ether) containing lipids. Using this approach, statistically significant differences in the abundances of numerous lipid species previously identified as being associated with cancer progression, or that play known roles as mediators in a range of physiological and pathological processes, were observed between the SW480 and SW620 cells. Most notably, these included increased plasmanylcholine and triglyceride lipid levels, decreased plasmenylethanolamine lipids, decreased C-16 containing sphingomyelin and ceramide lipid levels, and a dramatic increase in the abundances of total cholesterol ester and triglyceride lipids in the SW620 cells compared to those in the SW480 cells.

    The process of continuous ambulatory peritoneal dialysis has provided a useful, relatively inexpensive, and safe alternative for patients with end-stage renal disease. Infectious peritonitis, however, has limited a more widespread acceptance of this technique. The definition of peritonitis in this patient population is not universally accepted and does not always include the laboratory support of a positive culture (or Gram stain). In part, the omission of clinical microbiological findings stems from the lack of sensitivity of earlier microbiological efforts. Peritonitis results from decreased host phagocytic efficiency with depressed phagocytosis and bactericidal capacity of peritoneal macrophages. During episodes of peritonitis, fluid movement is reversed, away from the lymphatics and peritoneal membrane and toward the cavity. As a result, bloodstream infections are rare. Most peritonitis episodes are caused by bacteria. Coagulase-negative staphylococci are the most frequently isolated organisms, usually originating from the skin flora, but a wide array of microbial species have been documented as agents of peritonitis. Clinical microbiology laboratories need to be cognizant of the diverse agents so that appropriate primary media can be used. The quantity of dialysate fluid that is prepared for culture is critical and should constitute at least 10 ml. The sensitivity of the cultural approach depends on the volume of dialysate, its pretreatment (lysis or centrifugation), the media used, and the mode of incubation. The low concentration of microorganisms in dialysate fluids accounts for negative Gram stain results. Prevention of infection in continuous ambulatory peritoneal dialysis patients is associated with the socioeconomic status of the patient, advances in equipment (catheter) technology, and, probably least important, the application of prophylactic antimicrobial agents.

    Tuberculous peritonitis is a serious condition with rising prevalence in recent years. It is especially common in those patients with risk factors such as an immunocompromised state, chronic kidney disease, or cirrhosis/liver disease. Spread is typically hematogenous from pulmonary foci. We report on a 34-year-old man who presented with initial complaints of cough, low-grade fevers, abdominal pain, and nausea/vomiting. Chest x-ray showed a cluster of nodular opacities on the right upper lobe, and a CT scan showed diffuse thickening and nodularity of the omentum with prominent mesenteric lymph nodes, consistent with tuberculous peritonitis.

    Peritoneal dialysis-related peritonitis remains a major complication of peritoneal dialysis in patients with end-stage renal disease. Chryseobacterium indologenes is a rare organism that has been reported to cause infections mostly in hospitalised patients with severe underlying diseases. We report the first case of C indologenes peritonitis in a patient on peritoneal dialysis outside of Asia. Our patient with end-stage renal disease on peritoneal dialysis grew C indologenes from peritoneal fluid when he presented with abdominal pain and cloudy effluent. The patient responded well to intraperitoneal antibiotic therapy. Tenckhoff catheter did not require removal. This case demonstrates the importance of considering rare causes of peritonitis, such as C indologenes, in patients on peritoneal dialysis. Given the resistance of such organisms to commonly used broad-spectrum antibiotics, antimicrobial susceptibility testing must be assessed as early as possible to assure appropriate antibiotic coverage to avoid untreated peritonitis leading to peritoneal dialysis failure.

    To understand the impact of PIK3CA mutations on clinical characteristics and treatment response to epidermal growth factor tyrosine kinase inhibitors (EGFR TKIs) of lung adenocarcinoma, we examined PIK3CA and EGFR mutations in lung adenocarcinoma patients, and analyzed their clinical outcomes. Surgically excised tumor, bronchoscopy biopsy/brushing specimens and pleural effusions were prospectively collected from 1029 patients. PIK3CA and EGFR mutations were analyzed by RT-PCR and direct sequencing. In EGFR TKI-nave specimens, PIK3CA mutation rate was 1.8% (14/760). Twelve patients had coexisting PIK3CA and EGFR mutations. Among the 344 EGFR TKI-treated EGFR mutant patients, there was no significant difference in treatment response (p = 0.476) and progression-free survival (p = 0.401) of EGFR TKI between PIK3CA mutation-positive and negative patients. The PIK3CA mutation rate in lung adenocarcinoma with acquired resistance to EGFR TKI is not higher than that in EGFR TKI-naïve tissue specimens (2.9% (6/207) vs. 1.8%; p = 0.344). Of the 74 patients with paired specimens (TKI-naïve and acquired resistance to TKIs) only one patient (1.4%) developed acquired PIK3CA (E545K) mutation, and he also had acquired EGFR (T790M) mutation. In conclusion, PIK3CA mutation may not be associated with primary resistance to EGFR TKI among lung adenocarcinoma patients. Acquired PIK3CA mutation related to EGFR TKI treatment is rare.

    Metastatic pancreatic adenocarcinoma involving the testis is a rare condition with a poor prognosis. The current study describes the case of a 69-year-old male who presented with a painful swelling of the left scrotum. Scrotal ultrasonography revealed hydroceles in the scrotal sacs, with the left one being larger in size. The patient underwent left hydrocelectomy and was eventually diagnosed with metastatic adenocarcinoma. Abdominal computed tomography, which was performed to detect the primary cancer, showed a pancreatic tail carcinoma with liver and multiple lymph node metastases, and peritoneal carcinomatosis. The patient received gemcitabine-based chemotherapy but resulted in progressive disease. This case shows that in a patient in whom a primary testicular tumor is unusual due to their age, a testicular mass or hydrocele should be a suspect for possible metastatic disease. PMID:24932235

    The peritoneum is one of the locations outside the most common pulmonary tuberculosis. Peritoneal tuberculosis poses a public health problem in endemic regions of the world. The phenomenon of migration, the increased use of immunosuppressive therapy and the epidemic of AIDS have contributed to a resurgence of this disease in regions where it was previously controlled. The aim of this review is to expose the clinical, biologic end radiologic futures of the peritoneal tuberculosis and to present the methods of diagnosis and treatment. The diagnosis of this disease is difficult and still remains a challenge because of its insidious nature, the variability of presentation and limitations of available diagnostic tests. The disease usually presents a picture of lymphocytic exudative ascites. There are many complementary tests with variable sensitivities and specificities to confirm the diagnosis of peritoneal tuberculosis. Isolation of mycobacteria by culture of ascitic fluid or histological examination of peritoneal biopsy ideally performed by laparoscopy remains the investigation of choice. The role of PCR, ascitic adenosine deaminase, interferon gamma and the radiometric BACTEC system can improve the diagnostic yield. An antituberculous treatment with group 1 of the WHO for 6 months is sufficient in most cases.

    Abstract The incidence of Sjögren syndrome (SS) in primary biliary cirrhosis (PBC) patients is high. The influence of SS on the clinical outcomes of PBC patients, however, remains unclear. Our study retrospectively collected data on PBC-only patients and PBC patients with concomitant SS (PBC-SS) to compare the clinical differences of long-term outcomes between them. A total of 183 patients were diagnosed with PBC from January 1999 to December 2014 at our hospital. Of these, the authors excluded patients with diabetes, hypertension, advanced liver cirrhosis at initial diagnosis of PBC (Child–Turcotte–Pugh classification score of ≥7) and other liver diseases (ie, alcoholic liver disease, alpha-antitrypsin deficiency, viral hepatitis, and primary sclerosing cholangitis), and autoimmune diseases such as systemic lupus erythematosus and rheumatoid arthritis. Of the remaining 125 patients, 77 (61.6%) were PBC-only and 48 (38.4%) were PBC-SS patients. The mean follow-up duration was 8.76 years. During the observation period, the incidence of interstitial lung disease was higher in the PBC-SS group than in the PBC-only group (P = 0.005). The occurrence of spontaneous bacterial peritonitis was significantly different in PBC-SS patients than in PBC-only patients (P = 0.002). The overall survival was lower in PBC-SS patients than in PBC-only patients (P = 0.033). Although the incidence of hepatocellular carcinoma, end-stage renal disease, variceal bleeding, and hypothyroidism were all higher in the PBC-SS group than in the PBC-only group, the differences were not significant. Our study suggests that PBC-SS patients have a higher risk of developing interstitial lung disease and spontaneous bacterial peritonitis and have a poor prognosis. Aggressive surveillance of thyroid and pulmonary functions should therefore be performed in these patients. PMID:26765478

    More than 25 years after the last revision, in 2012 the FIGO Oncology Committee began revising the FIGO classification for staging ovarian, Fallopian tube and primary peritoneal cancers. The new classification has become effective with its publication at the beginning of 2014. Following recent findings on the pathogenesis of ovarian, Fallopian tube and primary peritoneal cancer and reflecting standard clinical practice, the three entities have now been classified uniformly. The histological subtype is included (high-grade serous – HGSC; low-grade serous – LGSC; mucinous – MC; clear cell – CCC; endometrioid – EC). Stages III and IV have been fundamentally changed: stage IIIA now refers to a localized tumor limited to the pelvis with (only) retroperitoneal lymph node metastasis (formerly classified as IIIC). Stage IV has been divided into IVA and IVB, with IVA defined as malignant pleural effusion and IVB as parenchymatous or extra-abdominal metastasis including inguinal and mediastinal lymph node metastasis as well as umbilical metastasis. A new WHO classification was published almost concurrently. The classification of serous tumors addresses the issue of the tubal carcinogenesis of serous ovarian cancer, even if no tubal precursor lesions are found for up to 30 % of serous high-grade cancers. The number of subgroups was reduced and subgroups now include only high-grade serous, low-grade serous, mucinous, seromucinous, endometrioid, clear cell and Brenner tumors. The category “transitional cell carcinomas” has been dropped and the classification “seromucinous tumors” has been newly added. More attention has been focused on the role of borderline tumors as a stage in the progression from benign to invasive lesions. PMID:26556905

    The incidence of Sjögren syndrome (SS) in primary biliary cirrhosis (PBC) patients is high. The influence of SS on the clinical outcomes of PBC patients, however, remains unclear. Our study retrospectively collected data on PBC-only patients and PBC patients with concomitant SS (PBC-SS) to compare the clinical differences of long-term outcomes between them.A total of 183 patients were diagnosed with PBC from January 1999 to December 2014 at our hospital. Of these, the authors excluded patients with diabetes, hypertension, advanced liver cirrhosis at initial diagnosis of PBC (Child-Turcotte-Pugh classification score of ≥7) and other liver diseases (ie, alcoholic liver disease, alpha-antitrypsin deficiency, viral hepatitis, and primary sclerosing cholangitis), and autoimmune diseases such as systemic lupus erythematosus and rheumatoid arthritis. Of the remaining 125 patients, 77 (61.6%) were PBC-only and 48 (38.4%) were PBC-SS patients.The mean follow-up duration was 8.76 years. During the observation period, the incidence of interstitial lung disease was higher in the PBC-SS group than in the PBC-only group (P = 0.005). The occurrence of spontaneous bacterial peritonitis was significantly different in PBC-SS patients than in PBC-only patients (P = 0.002). The overall survival was lower in PBC-SS patients than in PBC-only patients (P = 0.033). Although the incidence of hepatocellular carcinoma, end-stage renal disease, variceal bleeding, and hypothyroidism were all higher in the PBC-SS group than in the PBC-only group, the differences were not significant.Our study suggests that PBC-SS patients have a higher risk of developing interstitial lung disease and spontaneous bacterial peritonitis and have a poor prognosis. Aggressive surveillance of thyroid and pulmonary functions should therefore be performed in these patients. PMID:26765478

    Primary intestinal-type glandular lesions of the vagina are rare. We report a series of 14 lesions, including 1 intestinal-type polyp without neoplastic features, 3 adenomas (2 with high-grade dysplasia), and 10 adenocarcinomas. Patients ranged in age from 20 to 86 years (mean 60 y) and presented with vaginal bleeding or a mass. No history of diethylstilbestrol exposure, adenosis, or endometriosis was elicited in any patient. The lesions were mostly polypoid, small (0.8 to 2.0 cm), and located in the posterior (6 cases) and lower (7 cases) vagina. One carcinoma metastasized to a para-aortic lymph node; the others were confined to the vagina. The neoplasms exhibited histologic features identical to those seen in primary large intestinal tumors, including variable numbers of goblet cells and in 1 case neuroendocrine cells. Five of the adenocarcinomas contained areas consistent with a precursor adenoma. In 3 cases, a benign urothelium-lined duct was adjacent to the lesion, and in 2 patients benign intestinal-type epithelium was present; no other potential benign precursor lesions were seen. Immunohistochemical analysis was performed on 6 cases; the tumors were positive for CDX-2 (6/6), CK20 (5/6), CEA (5/5), CK7 (4/6), and CA-125 (2/4) and were negative for ER (0/6) and p16 (0/2). Clinical outcome data were available in 3 patients with adenocarcinomas; 1 died of disease in <1 year, and 2 were alive with no evidence of disease at 2 and 7 years. The pertinent literature is reviewed, and the potential origin and differential diagnosis of these lesions are discussed. PMID:24722061

    Purpose Veliparib, a poly(ADP-ribose) polymerase (PARP) inhibitor, demonstrated clinical activity in combination with oral cyclophosphamide in patients with BRCA-mutant solid tumors in a phase 1 trial. To define the relative contribution of PARP inhibition to the observed clinical activity, we conducted a randomized phase 2 trial to determine the response rate of veliparib in combination with cyclophosphamide compared to cyclophosphamide alone in patients with pretreated BRCA-mutant ovarian cancer or in patients with pretreated primary peritoneal, fallopian tube, or high-grade serous ovarian cancers (HGSOC). Methods Adult patients were randomized to receive cyclophosphamide alone (50 mg orally once daily) or with veliparib (60 mg orally once daily) in 21-day cycles. Crossover to the combination was allowed at disease progression. Results Seventy-five patients were enrolled and 72 were evaluable for response; 38 received cyclophosphamide alone and 37 the combination as their initial treatment regimen. Treatment was well tolerated. One complete response was observed in each arm, with three partial responses (PR) in the combination arm and six PRs in the cyclophosphamide alone arm. Genetic sequence and expression analyses were performed for 211 genes involved in DNA repair; none of the detected genetic alterations were significantly associated with treatment benefit. Conclusion This is the first trial that evaluated single agent, low dose cyclophosphamide in HGSOC, peritoneal, fallopian tube, and BRCA-mutant ovarian cancers. It was well tolerated and clinical activity was observed; the addition of veliparib at 60 mg daily did not improve either the response rate or the median progression free survival. PMID:25589624

    Cancer of the urachus is very unusual. The lesion is a mucosecretory adenocarcinoma. The diagnosis is usually established late, and has a serious prognosis because of a long clinical latency. We report a case of metastatic adenocarcinoma of the urachus revealed by hematuria. A review of the literature allows us to demonstrate the rarity of this tumour and to demonstrate its various clinical, histological, radiological and therapeutical aspects.

    The newly proposed International Association for the Study of Lung Cancer, American Thoracic Society, and European Respiratory Society (IASLC/ATS/ERS) classification of lung adenocarcinoma has emphasized the prognostic significance of histological subtyping. In this study, 2 surgical pathologists reevaluated 49 consecutive cases of invasive primary pulmonary adenocarcinomas; histological subtyping was performed according to the IASLC/ATS/ERS classification. The 2 reviewers agreed on the predominant pattern in 23 out of 32 independently reviewed cases (71.9%, k = 0.628, 95% confidence interval = 0.442-0.815). Postconsensus, a complex glandular pattern consisting of fused, closely packed glands and cribriform architecture was identified in 9 of 49 (18%) cases. This pattern has a strong association with lymphovascular invasion (78%; P = .0091), high mitotic activity (89%), and higher tumor stage (78%). Frequent association of complex glandular pattern with poor prognostic factors and its overlap with acinar pattern warrant a more detailed description of this pattern in the classification system and a large-scale study to evaluate its prognostic significance.

    Abstract Background: The urachus is a vestigial tubular structure that connects the urinary bladder to the allantois during early embryonic development. Urachal carcinoma develops in the urachus, which is an embryological remnant of the urogenital sinus and allantois. The estimated annual incidence of urachal carcinoma in the general population is 0.01% of all cancers in adults. Moreover, urachal carcinoma accounts for 0.34% to 0.7% of all bladder carcinoma cases. And breast metastasis is extremely rarer. Methods and Results: A 42-year-old woman was admitted to our hospital with a palpable mass in the outer upper quadrant of the right breast, which was misinterpreted as a carcinoma that originated from the breast. Subsequently, she underwent surgery without any further meticulous examination. Immunohistochemistry analysis revealed positivity for CK20, Villin, and CDX-2 and negativity for CK7. After further inspection, a mass was found in the bladder dome using 18F-fluorodeoxyglucose positron emission tomography and computed tomography. The mass was surgically removed. Conclusion: Pathologic and immunohistochemical examination confirmed that the mass was urachal mucinous adenocarcinoma and mucinous adenocarcinoma to the right breast. The patient has been followed up without recurrence for 8 months. PMID:27583877

    Background Epithelial cell adhesion molecule (epcam) is a multifunctional transmembrane glycoprotein expressed on both normal epithelium and epithelial neoplasms such as gastric, breast, and renal carcinomas. Recent studies have proposed that the proteolytic cleavage of the intracellular domain of epcam (epcam-icd) can trigger signalling cascades leading to aggressive tumour behavior. The expression profile of epcam-icd has not been elucidated for primary colorectal carcinoma. In the present study, we examined epcam-icd immunohistochemical staining in a large cohort of patients with primary colorectal adenocarcinoma and assessed its performance as a potential prognostic marker. Methods Immunohistochemical staining for epcam-icd was assessed on tissue microarrays consisting of 137 primary colorectal adenocarcinoma samples. Intensity of staining for each core was scored by 3 independent pathologists. The membranous epcam-icd staining score was calculated as a weighted average from 3 core samples per tumour. Univariate analysis of the average scores and clinical outcome measures was performed. Results The level of membranous epcam-icd staining was positively associated with well-differentiated tumours (p = 0.01); low preoperative carcinoembryonic antigen (p = 0.001); and several measures of survival, including 2-year (p = 0.02) and 5-year survival (p = 0.05), and length of time post-diagnosis (p = 0.03). A number of other variables—including stage, grade, and lymph node status—showed correlations with epcam staining and markers of poor outcome, but did not reach statistical significance. Conclusions Low membranous epcam-icd staining might be a useful marker to identify tumours with aggressive clinical behavior and potential poor prognosis and might help to select candidates who could potentially benefit from treatment targeting epcam.

    The presence of peritoneal implants detected by computered axial tomography (CT) is usually related to mesothelial primary neoformative processes or, more frequently to peritoneal metastasis or peritoneal carcinomatosis. Although the higher prevalence of neoplastic processes in the chronic renal failure population, the association of peritoneal implants and constitutional syndrome is not always correlated to peritoneal carcinomatosis. We present the case of two patients with chronic renal failure in hemodialysis programme, with abdominal insidious clinical, constitutional syndrome and similar peritoneal implants seen by CAT: the histologic analysis of peritoneal implants gave the definitive diagnostic of secondary amyloidosis and peritoneal tuberculosis respectively.

    A primary ductal adenocarcinoma (PDA) of the lacrimal gland is a rare distinct subtype of an epithelial tumor arising in the lacrimal gland. PDA is the counterpart of salivary duct carcinoma (SDC) resembling an invasive ductal carcinoma (IDC) of the breast. In our case, PDA revealed histopathological and immunohistochemical results corresponding to SDC. Interestingly, the tumor cells showed intracytoplasmic vacuoles containing dense eosinophilic hyaline globules at light microscopy. Ultrastructurally, the tumor cells exhibited microvilli-lined intracytoplasmic lumen containing homogenous electron-dense secretory products. A previous study demonstrated that numerous intracytoplasmic lumens of tumor cells are favored breast malignant tumor, similar to the histopathology of PDA, rather than benign lesion. This characteristic finding may be meaningful to diagnose high grade epithelial tumors including PDA.

    EML4-ALK is a new driver gene of non-small cell lung cancer and a target of crizotinib. The objectives of this study were to determine the frequency of ALK rearrangements in a large cohort of patients with primary lung adenocarcinoma and to analyze the association of ALK rearrangements with clinicopathological characteristics and clinical outcomes. The roles of fluorescence in situ hybridization (FISH), Ventana immunohistochemistry (IHC), and reverse transcriptase polymerase chain reaction (RT-PCR) in the detection of ALK rearrangements were evaluated. The ALK rearrangement was detected in 430 specimens from individual patients with primary lung adenocarcinoma using FISH and Ventana IHC based on tissue microarrays. The EGFR status was detected in all of the specimens through DNA sequencing. An RT-PCR was performed on 200 of the specimens and confirmed by sequencing. Of the 430 patients, 46 (10.7%) harbored ALK rearrangements. The ALK rearrangements were associated with a younger age and the EGFR wild type in comparison with ALK-negative patients. The sensitivity and specificity of the Ventana IHC were 100% and 98.2%, respectively, and the concordance rate between the FISH and the Ventana IHC was 98.4%. The sensitivity and specificity of RT-PCR were 95.5% and 87.0%, respectively, and the concordance rate between the FISH and the RT-PCR was 89.0%. The Cox analysis indicated that an early stage and EGFR-activating mutations were independently associated with a longer OS. This study demonstrated that ALK rearrangements are associated with a younger age and the EGFR wild type rather than with other clinicopathological factors. Although the FISH and Ventana IHC have better concordance, and RT-PCR is a more sensitive method and can identify different variants or partners, the IHC and RT-PCR need to be further evaluated in clinical trials to identify their roles in guiding patients' targeted therapy using crizotinib.

    The proportion of peritoneal mesotheliomas among all mesotheliomas has been decreasing, leading some to suggest that peritoneal mesothelioma occurs only after high levels of exposure to asbestos. To investigate the relationship between asbestos exposure and the development of peritoneal mesothelioma, a case-control study examined 40 cases of primary peritoneal mesothelioma from a single institution. This series differed from previous reports in that 75% of the cases and controls had attended college. Results show an odds ratio of 6.6 for asbestos exposure among this group of primary peritoneal mesothelioma cases with relatively slight asbestos exposures.

    The term peritonitis indicates an inflammatory process involving the peritoneum that is most frequently infectious in nature. Primary or spontaneous bacterial peritonitis (SBP) typically occurs when a bacterial infection spreads to the peritoneum across the gut wall or mesenteric lymphatics or, less frequently, from hematogenous transmission in combination with impaired immune system and in absence of an identified intra-abdominal source of infection or malignancy. The clinical presentation of SBP is variable. The condition may manifest as a relatively insidious colonization, without signs and symptoms, or may suddenly occur as a septic syndrome. Laboratory diagnostics play a pivotal role for timely and appropriate management of patients with bacterial peritonitis. It is now clearly established that polymorphonuclear leukocyte (PMN) in peritoneal fluid is the mainstay for the diagnosis, whereas the role of additional biochemical tests is rather controversial. Recent evidence also suggests that automatic cell counting in peritoneal fluid may be a reliable approach for early screening of patients. According to available clinical and laboratory data, we have developed a tentative algorithm for efficient diagnosis of SBP, which is based on a reasonable integration between optimization of human/economical resources and gradually increasing use of invasive and expensive testing. The proposed strategy entails, in sequential steps, serum procalcitonin testing, automated cell count in peritoneal fluid, manual cell count in peritoneal fluid, peritoneal fluid culture and bacterial DNA testing in peritoneal fluid.

    A comprehensive pathological report is essential for optimal patient management, cancer staging and prognostication. In many countries, proforma reports are used but these vary in their content. The International Collaboration on Cancer Reporting (ICCR) is an alliance formed by the Royal College of Pathologists of Australasia, the Royal College of Pathologists of the United Kingdom, the College of American Pathologists, the Canadian Partnership Against Cancer and the European Society of Pathology, with the aim of developing an evidence-based reporting data set for each cancer site. This will reduce the global burden of cancer data set development and reduplication of effort by different international institutions that commission, publish and maintain standardised cancer reporting data sets. The resultant standardisation of cancer reporting will benefit not only those countries directly involved in the collaboration but also others not in a position to develop their own data sets. We describe the development of a cancer data set by the ICCR expert panel for the reporting of primary ovarian, fallopian tube and peritoneal carcinoma and present the 'required' and 'recommended' elements to be included in the report with an explanatory commentary. This data set encompasses the recent International Federation of Obstetricians and Gynaecologists staging system for these neoplasms and the updated World Health Organisation Classification of Tumours of the Female Reproductive Organs. The data set also addresses issues about site assignment of the primary tumour in high-grade serous carcinomas and proposes a scoring system for the assessment of tumour response to neoadjuvant chemotherapy. The widespread implementation of this data set will facilitate consistent and accurate data collection, comparison of epidemiological and pathological parameters between different populations, facilitate research and hopefully will result in improved patient management.

    N-of-1 trials target actionable mutations, yet such approaches do not test genomically-informed therapies in patient tumor models prior to patient treatment. To address this, we developed patient-derived xenograft (PDX) models from fine needle aspiration (FNA) biopsies (FNA-PDX) obtained from primary pancreatic ductal adenocarcinoma (PDAC) at the time of diagnosis. Here, we characterize PDX models established from one primary and two metastatic sites of one patient. We identified an activating KRAS G12R mutation among other mutations in these models. In explant cells derived from these PDX tumor models with a KRAS G12R mutation, treatment with inhibitors of CDKs (including CDK9) reduced phosphorylation of a marker of CDK9 activity (phospho-RNAPII CTD Ser2/5) and reduced viability/growth of explant cells derived from PDAC PDX models. Similarly, a CDK inhibitor reduced phospho-RNAPII CTD Ser2/5, increased apoptosis, and inhibited tumor growth in FNA-PDX and patient-matched metastatic-PDX models. In summary, PDX models can be constructed from FNA biopsies of PDAC which in turn can enable genomic characterization and identification of potential therapies. PMID:26934555

    Alternatively spliced Tissue Factor (asTF) is a secreted form of Tissue Factor (TF), the trigger of blood coagulation whose expression levels are heightened in several forms of solid cancer, including pancreatic ductal adenocarcinoma (PDAC). asTF binds to β1 integrins on PDAC cells, whereby it promotes tumor growth, metastatic spread, and monocyte recruitment to the stroma. In this study, we determined if targeting asTF in PDAC would significantly impact tumor progression. We here report that a novel inhibitory anti-asTF monoclonal antibody curtails experimental PDAC progression. Moreover, we show that tumor-derived asTF is able to promote PDAC primary growth and spread during early as well as later stages of the disease. This raises the likelihood that asTF may comprise a viable target in early- and late-stage PDAC. In addition, we show that TF expressed by host cells plays a significant role in PDAC spread. Together, our data demonstrate that targeting asTF in PDAC is a novel strategy to stem PDAC progression and spread. PMID:26967388

    Antibiotherapy remains one of the basic clinical tools, which can influence the evolution of severe peritonitis. Peritoneal biofilm formation may minimize the antibiotic effects due to dramatic growth of Minimum Inhibitory Concentrations (MIC) and Minimum Bactericidal Concentrations (MBC) for matrix-enclosed bacteria. In this paper we demonstrate the presence and evolution of bacterial biofilms on the peritoneal surface during the course of severe secondary peritonitis using an experimental model and clinical material. Cecal Ligation Puncture was performed in 20 mice Swiss Webster. Peritoneal samples were studied at optic and electronic microscope at 10, 24, 48 and 72 hours postoperative. Clinical samples were taken from 10 patients with diffuse peritonitis. At 24 hours after the onset of the peritonitis bacterial colonies were detected on the peritoneal surface. The formation of mature multilayer polymicrobial biofilms with deep penetration in abdominal wall by 48-72 hours was documented. The bacterial biofilms appear in first 24 hours in the course of experimental generalized peritonitis. Our experimental and clinical data demonstrate formation of the mature polymicrobial biofilm in 48-72 hours after the onset of peritonitis. The possibility of resistant biofilm formation in secondary diffuse peritonitis should be taken into consideration in elaboration of treatment schemes.

    Background A need for follow-up recommendations for survivors of fallopian tube, primary peritoneal, or epithelial ovarian cancer after completion of primary treatment was identified by Cancer Care Ontario’s Program in Evidence-Based Care. Methods We searched for existing guidelines, conducted a systematic review (medline, embase, and cdsr, January 2010 to March 2015), created draft recommendations, and completed a comprehensive review process. Outcomes included overall survival, quality of life, and patient preferences. Results The Cancer Australia guidance document Follow Up of Women with Epithelial Ovarian Cancer was adapted for the Ontario context. A key randomized controlled trial found that the overall survival rate did not differ between asymptomatic women who received early treatment based on elevated serum cancer antigen 125 (ca125) alone and women who waited for the appearance of clinical symptoms before initiating treatment (hazard ratio: 0.98; 95% confidence interval: 0.80 to 1.20; p = 0.85); in addition, patients in the delayed treatment group reported good global health scores for longer. No randomized studies were found for other types of follow-up. We recommend that survivors be made aware of the potential harms and benefits of surveillance, including a discussion of the limitations of ca125 testing. Women could be offered the option of no formal follow-up or a follow-up schedule that is agreed upon by the woman and her health care provider. Education about the most common symptoms of recurrence should be provided. Alternative models of care such as nurse-led or telephone-based follow-up (or both) could be emerging options. Conclusions The recommendations provided in this guidance document have a limited evidence base. Recommendations should be updated as further information becomes available. PMID:27803599

    ETV6-NTRK3 fusion was identified in several cancers including the recently described mammary analog secretory carcinoma (MASC) of the salivary glands and a minority of papillary thyroid carcinomas. We describe three cases of primary MASC of the thyroid gland and provide a detailed clinical and pathological characterization of the tumor morphology, immunoprofile, and genetic background. Immunohistochemistry for PAX8, TTF-1, thyroglobulin, mammaglobin, GCDFP-15, S-100 protein, and p63 was used to define the tumor immunophenotype. Fluorescence in situ hybridization for ETV6 rearrangement was performed in three, and the next-generation sequencing assay MSK-IMPACT™ (Memorial Sloan Kettering-Integrated Mutation Profiling of Actionable Cancer Targets) was performed in two cases. Primary MASC of the thyroid occurred in two women and one man, age 47-72 years. All patients presented with high T stage, infiltrative, locally aggressive tumors with extrathyroidal extension. Two cases were associated with well-differentiated papillary thyroid carcinoma. Histologically, they appeared as low-grade tumors, resembling MASC of the salivary glands and labeled positive for mammaglobin, GCDFP-15, S-100 protein, p63, weakly positive for PAX8, and negative for TTF-1 and thyroglobulin. Fluorescence in situ hybridization revealed ETV6 rearrangement in all cases. In two tested cases MSK-IMPACT™ confirmed the presence of ETV6-NTRK3 gene fusion. Two patients had at least two local recurrences, one was alive with disease, and one was alive and free of disease after 14 and 17 years, respectively. The third patient was alive and free of disease after 2 years. MASC of the thyroid is histologically, immunophenotypically, and genetically similar to its salivary gland counterpart. Thyroid MASC can be associated with a well-differentiated papillary thyroid carcinoma component, supporting follicular cell origin. Clinically, these carcinomas may show frequent recurrences but are associated with long

    Sinonasal adenocarcinoma is a rare neoplasm which is classified as 'intestinal' or 'nonintestinal' type, depending on its resemblance to gastrointestinal mucosa. These tumors are associated with occupational and environmental carcinogens. In this study, a fifty-year-old oil-painter male patient with a low-grade nonintestinal type sinonasal adenocarcinoma originating from the left middle concha and ethmoid sinus is presented. Microscopical examination revealed many infiltrative glandular structures, most of which were cystically dilated and some of which were smaller in diameter, arranged back to back in loose fibrous stroma as well as intraglandular papillary and micropapillary structures forming complex branches or a cribriform pattern. The glands were lined by epithelial cells that were faintly eosinophilic and relatively abundant cubical/ cylinderical cytoplasms and mildly pleomorphic round/oval nuclei, with rare mitotic figures. Intraluminal and focally intracytoplasmic mucin was demonstrated with Alcian Blue, mucicarmin and PAS stains. Immunohistochemically, tumor cells were strongly and diffusely positive with CK7; focally and weakly positive with CK20 and negative with CDX2 in accordance with the nonintestinal type. S-100, Actin and p63, applied for investigating the myoepithelial and salivary glandular origins, were all negative. Prognostic markers, TTF-1 and p53 were negative; while the Ki-67 index was 2%. The fact that intestinal type sinonasal adenocarcinomas are generally high grade, while nonintestinal tumors are histologically low grade makes this morphological and immunohistochemical-based classification valuable in predicting the prognosis of the disease. In addition to the morphological and immunohistochemical findings, clinical information stands out in the differentiation of the tumor from benign or malignant primary lesions or metastatic adenocarcinoma.

    A case is presented of a 36-year-old male with primary sclerosing cholangitis-associated inflammatory bowel disease (PSC-IBD) and two synchronous stage 1 adenocarcinomata of the colon, who was initially treated with a subtotal colectomy with ileostomy. One year later, the patient presented with extensive intra-abdominal lymphadenopathy and peritoneal carcinomatosis, as well as a markedly elevated serum level of alpha-fetoprotein (AFP). Fine needle aspiration biopsy of a porta hepatis lymph node revealed a metastatic hepatoid adenocarcinoma. Subsequent review of the previous colectomy specimen showed that one of the previously identified adenocarcinomata had features suggestive of a hepatoid colonic adenocarcinoma. The patient was subsequently treated with a cytotoxic regimen of FOLFOX (oxaliplatin, leucovorin, 5-fluorouracil) and bevacizumab, with stable results being achieved after six months. This case presents the first known report of PSC-IBD associated with synchronous typical and hepatoid adenocarcinomata of the colon and highlights the importance of considering hepatoid adenocarcinoma as a differential diagnosis in patients with an increasing serum AFP level.

    Circulating tumor cells (CTCs) are important biomarkers of cancer progression and metastatic potential. The rarity of CTCs in peripheral blood has driven the development of technologies to isolate these tumor cells with high specificity; however, there are limited techniques available for isolating target CTCs following enumeration. A strategy is described to capture and isolate viable tumor cells from whole blood using an array of releasable microstructures termed micropallets. Specific capture of nucleated cells or cells expressing epithelial cell adhesion molecules (EpCAM) was achieved by functionalizing micropallet surfaces with either fibronectin, Matrigel or anti-EpCAM antibody. Surface grafting of poly(acrylic acid) followed by covalent binding of protein A/G enabled efficient capture of EpCAM antibody on the micropallet surface. MCF-7 cells, a human breast adenocarcinoma, were retained on the array surface with 90±8% efficiency when using an anti-EpCAM-coated array. To demonstrate the efficiency of tumor cell retention on micropallet arrays in the presence of blood, MCF-7 cells were mixed into whole blood and added to small arrays (71 mm(2)) coated with fibronectin, Matrigel or anti-EpCAM. These approaches achieved MCF-7 cell capture from ≤10 µL of whole blood with efficiencies greater than 85%. Furthermore, MCF-7 cells intermixed with 1 mL blood and loaded onto large arrays (7171 mm(2)) were captured with high efficiencies (≥97%), could be isolated from the array by a laser-based approach and were demonstrated to yield a high rate of colony formation (≥85%) after removal from the array. Clinical utility of this technology was shown through the capture, isolation and successful culture of CTCs from the blood of mice engrafted with primary human pancreatic tumors. Direct capture and isolation of living tumor cells from blood followed by analysis or culture will be a valuable tool for cancer cell characterization.

    A modification of the procedure of laparostomy with palisade dorsoventral lavage for treating neglected peritonitis is described. It consists of adding a polyethylene foil to cover the intestines and thus avoiding the direct contact between them from one side, and the suction drains and the palisade laparostomy screen from the other. Between 1988 and 1995, 19 patients with neglected peritonitis (APACHE II scores from 12 to 42; mean 22.3) were managed using this modified technique. A total of 81 reexplorations were done (average, 4.3 reexplorations per patient). The technique proved effective (21% mortality, n = 4). No intestinal perforations, fistulas, or residual pus collections occurred among survivors or among those who died. Primary fascial closure was achieved in all survivors and during an 18-months followup, no incisional hernia occurred. Based on these results, we believe this technique is extremely useful when both laparostomy and continuous peritoneal irrigations are considered in patients with neglected peritonitis.

    Peritonitis is an important cause of morbidity in patients undergoing peritoneal dialysis. Rothia mucilaginosa has been reported as an unusual cause of peritoneal dialysis associated peritonitis. Difficulty in the management of this microorganism lies in the absence of uniform recommendations for anti-microbial therapy directed against this pathogen. The current report describes the clinical course of an episode of peritoneal dialysis associated peritonitis caused by Rothia mucilaginosa. Treatment options for this organism are summarized.

    We initiated a therapeutic program of continuous ambulatory peritoneal dialysis for patients with chronic renal failure. Our program resulted in many episodes of peritonitis arising from contamination due to the technical aspects of the procedure. Microbiologic evaluation showed that 73% of 97 episodes were culture positive, with gram-positive organisms causing most of the cases, especially early in dialysis. Gram-negative rods tended to occur later. Gram stains of dialysate effluent resulted in a disappointingly low yield of only 9% positivity. Cell counts were a dependable indicator of the presence of peritoneal inflammation and also of therapeutic success. Most patients responded well to intraperitoneal cephalothin, 125 mg/L for 10 to 14 d. The occurrence of peritonitis resulted in 0.93 years of hospitalization during the total of 15.45 patient-years on dialysis, which essentially negated the financial advantages of this method of treatment of chronic renal failure. For this to be a successful mode of therapy, advances in the prevention of peritonitis must be made. PMID:6985785

    The incidence of masses in pregnancy is estimated to occur in 1/81 to 1/2,500 pregnancies. The development of colorectal carcinoma during pregnancy is a more rare event, with less than 30 cases above the peritoneal reflection reported in the last 70 years. The differential diagnosis of mucinous adenocarcinoma of ovarian vs. gastrointestinal origin is often difficult. We report a pregnant patient affected by advanced colorectal cancer, who presented with an asymptomatic unilateral adnexal mass on ultrasound. A 28-year old woman was referred to our hospital after a routine ultrasound examination at 26 weeks gestation showing a right adnexal mass. At elective exploratory laparotomy, the patient was found to have metastatic mucinous adenocarcinoma. Diagnostic and treatment choices of such a cancer in a pregnant patient were explored. The final diagnosis of colorectal cancer was made only at the time of a subsequent emergency laparotomy. The goal of an obstetrician/gynecologist and other care givers of pregnant patients, is to achieve a healthy mother and child. Unfortunately, physicians may unwillingly sacrifice the health of the mother by denying or delaying her procedures or treatments simply because she is pregnant. It is especially important in the case of adnexal masses and their related pathology, due to the difficulty in detection and management of such cases during pregnancy, that doctors actively assume the responsibility of assuring that pregnant patients receive the proper care they need.

    A 74-year-old woman was referred because of rheumatic symptoms consisting of pain, swelling of the hands, contracture and flexion of the fingers and severe palmar erythrosis. One year earlier she had undergone a total abdominal hysterectomy (TAH) for uterine adenocarcinoma. A paraneoplastic syndrome with palmar fasciitis and arthritis was then suspected and an evolutive peritoneal carcinomatosis was confirmed by abdominal CT scan. The patient was first treated with hormonal therapy (progestagen) and then with chemotherapy. This, associated with calcitonin, corticosteroids and physiotherapy, allowed a temporary recovery, but the patient died 10 months later from progressive peritoneal carcinomatosis.

    OBJECTIVE. The authors review current definition, classification, scoring, microbiology, inflammatory response, and goals of management of secondary peritonitis. SUMMARY BACKGROUND DATA. Despite improved diagnostic modalities, potent antibiotics, modern intensive care, and aggressive surgical treatment, up to one third of patients still die of severe secondary peritonitis. Against the background of current understanding of the local and systemic inflammatory response associated with peritonitis, there is growing controversy concerning the optimal antibiotic and operative therapy, intensified by lack of properly conducted randomized studies. In this overview the authors attempt to outline controversies, suggest a practical clinical approach, and highlight issues necessitating further research. METHODS. The authors review the literature and report their experience. RESULTS. The emerging concepts concerning antibiotic treatment suggest that less-in terms of the number of drugs and the duration of treatment-is better. The classical single operation for peritonitis, which obliterates the source of infection and purges the peritoneal cavity, may be inadequate for severe forms of peritonitis; for the latter, more aggressive surgical techniques are necessary to decompress increased intra-abdominal pressure and prevent or treat persistent and recurrent infection. The widespread acceptance of the more aggressive and demanding surgical methods has been hampered by the lack of randomized trials and reportedly high associated morbidity rates. CONCLUSIONS. Sepsis represents the host's systemic inflammatory response to bacterial peritonitis. To improve results, both the initiator and the biologic consequences of the peritoneal infective-inflammatory process should be addressed. The initiator may be better controlled in severe forms of peritonitis by aggressive surgical methods, whereas the search for methods to abort its systemic consequences is continuing. PMID:8678610

    The aim of this study is to present 2 rare cases of cutaneous metastases originated from adenocarcinoma of the gastro-esophageal junction, thus, underline the need for early diagnosis and possible treatment of suspicious skin lesions among patients with esophageal malignancy. Metastatic cancer to the skin originated from internal malignancies, mostly lung cancer, breast cancer, and colorectal cancer, constitute 0.5 to 9% of all metastatic cancers.5,8,15 Skin metastases, mainly from squamous cell carcinomas of the esophagus, are rarely reported. Cutaneous metastasis is a finding indicating progressiveness of the disease.17 More precisely, median survival is estimated approximately 4.7 months.2,14 This study is a retrospective review of 2 cases of patients with adenocarcinoma of the esophagus and a review of the literature. Two patients aged 60 and 32 years old, respectively, underwent esophagectomy. Both pathologic reports disclosed adenocarcinoma of the gastro-esophageal junction staged T3 N2 M0 (stage IIIB). During follow-up time, the 2 patients were diagnosed with cutaneous metastases originated from the primary esophageal tumor 11 and 4 months after surgery, respectively. The first patient is alive 37 months after diagnosis, while the second one died 16 months after surgery. Cutaneous metastasis caused by esophageal adenocarcinoma is possible. Therefore, follow-up of patients who were diagnosed with esophageal malignancy and underwent esophagectomy is mandatory in order to reveal early surgical stages. PMID:25785344

    According to the National Registry of Renal Replacement Therapy (RRT), the incidence of chronic kidney disease (end-stage renal disease) and the need of RRT have declined in the last decade renal. One of the reasons for this tendency certainly is transplantation as the best choice. However, transplant procedure has limitations in elderly patients due to the number of comorbidities. This study was designed as retrospective analysis of outcomes in patients treated with peritoneal dialysis for a period of eleven years. Patients were divided into those who had been assisted or unassisted. Out of 100 patients treated with peritoneal dialysis (PD), 77 completed the treatment, including 26 assisted and 51 unassisted patients. Peritonitis was recorded in 20 assisted and 26 unassisted patients. Peritonitis was more common in unassisted patients, who were more frequently lost from PD. Assisted PD could be a good and safe choice of RRT in this special group of patients.

    Benign multicystic mesothelioma is a rare tumour that originates from the abdominal peritoneum with a predisposition to the pelvic peritoneum. It typically affects women of reproductive age. There have been less than 200 cases of this rare neoplasia reported to date. We present the case of a 35-year-old woman who was referred to our centre because of the detection of a peritoneal carcinomatosis during a gynaecological exam. A diagnostic laparoscopy was performed. The findings included multiple cysts appearing as ‘a bunch of grapes’ occupying the omentum. Biopsies were taken during the surgery and the results showed benign multicystic peritoneal mesothelioma. Benign multicystic mesothelioma can simulate other conditions, such as malignant ovarian tumours or cystic lymphangioma. It is often diagnosed accidentally during surgery performed for another reason. The diagnosis is interoperative, observing multicystic structures grouped as a ‘bunch of grapes’ containing clear fluid with thin walls made of connective tissue. Immunohistochemistry confirmed mesothelial origin. Surgery is considered the treatment of choice and is based on the removal of the cysts from the abdominal cavity. Hyperthermic intraperitoneal chemotherapy can be considered as a primary treatment in patients with recurrences or even as a part of primary treatment associated with surgery. Survival at 5 years is 100% and invasive or malignant progression is extraordinary. The treatment approach should be multidisciplinary, and the patient should be referred to a referral centre.

    Urothelial cancer is the most frequently diagnosed type of malignant tumor in the bladder, of which primary adenocarcinoma accounts for a small percentage. Secondary malignancies, in particular metastatic adenocarcinoma from the lung, are exceedingly rare, with only six cases previously reported in the literature. The present study describes the case of a 71-year-old Chinese male patient with known lung cancer for >2 years, who was diagnosed with metastatic adenocarcinoma to the bladder. The histopathological characteristics and immunohistochemical features of the patient are reported. It was proposed that pathologists should consider the possibility of metastatic adenocarcinoma from the lung, rather than assume a diagnosis of primary adenocarcinoma of the bladder or direct invasion of adenocarcinoma from the surrounding organs. Furthermore, it is essential to determine the medical history of each patient and observe the immunohistochemical features of all tumors prior to diagnosis. PMID:26622730

    Introduction Acute primary peritonitis due to group A Streptococci (GAS) is a rare but life-threatening infection. Unlike other forms of primary peritonitis it affects predominantly young previously healthy individuals and thus is often confused with the more frequent secondary peritonitis. A case series of three patients is presented as well as a review of the literature focusing on pitfalls in the diagnose and therapy of GAS peritonitis. Methods A retrospective analysis of three patients with primary GAS peritonitis was performed. Furthermore a systematic review of all cases of primary GAS peritonitis published from 1990 to 2013 was performed comparing demographics and clinical presentation, as well as radiological imaging, treatment and outcome. Results All three female patients presented initially with high fever, nausea and severe abdominal pain. Radiological imaging revealed intraperitoneal fluid collections of various degrees, but no underlying cause of peritonitis. Broad antibiotic treatment was started and surgical exploration was performed for acute abdomen in all three cases. Intraoperatively fibrinous peritonitis was observed, but the correct diagnosis was not made until microbiological analysis confirmed GAS peritonitis. One patient died within 24 h after admission. The other two patients recovered after multiple surgeries and several weeks on the intensive care unit due to multiple organ dysfunction syndrome. The fulminant clinical course of the three patients resembled those of many of the published cases: flu-like symptoms, high fever, severe acute abdominal pain and fibrinous peritonitis without obvious infectious focus were the most common symptoms reported in the literature. Conclusion GAS primary peritonitis should be considered in particular in young, previously healthy women who present with peritonitis but lack radiological findings of an infectious focus. The treatment of choice is immediate antibiotic therapy. Surgical intervention is

    Ovarian high-grade serous carcinoma is an aggressive malignancy with poor prognosis. Optimal surgical debulking and tumor sensitivity to platinum-based chemotherapy are 2 well-established prognostics for this tumor type. Molecular markers that identify more clinically aggressive tumors would potentially allow for the development of individualized treatment options. PTEN is a key negative regulator of the PI3K signaling pathway. Loss of PTEN expression in endometrial carcinoma is associated with endometrioid histology; women with endometrioid tumors have a better prognosis than those with nonendometrioid tumors. The prognostic and predictive value for PTEN has not been effectively explored in ovarian/peritoneal high-grade serous carcinoma. PTEN immunohistochemistry was assessed in 126 women with Stage III, high-grade serous carcinoma of the ovary/peritoneum treated with surgery and then a platinum-based regimen. Compared with PTEN-negative or PTEN-reduced tumors, positive PTEN immunohistochemistry, detected in 58% of tumors, was associated with decreased pS6 and increased PTEN mRNA levels. Positive PTEN expression was independent of surgical debulking status or platinum sensitivity. PTEN-positive tumors were associated with significantly decreased recurrence-free survival. Importantly, the devised PTEN immunohistochemistry scoring system was reproducible among pathologists.

    Feline infectious peritonitis virus (FIPV) causes a mostly fatal, immunologically mediated disease in cats. Previously, we demonstrated that immunization with a recombinant vaccinia virus expressing the FIPV spike protein (S) induced early death after challenge with FIPV (Vennema et al., 1990, J. Virol. 64, 1407-1409). In this paper we describe similar immunizations with the FIPV membrane (M) and nucleocapsid (N) proteins. The genes encoding these proteins were cloned and sequenced. Comparison of the amino acid sequences with the corresponding sequences of porcine transmissible gastroenteritis virus revealed 84.7 and 77% identity for M and N, respectively. Vaccinia virus recombinants expressing the cloned genes induced antibodies in immunized kittens. Immunization with neither recombinant induced early death after challenge with FIPV, strongly suggesting that antibody-dependent enhancement is mediated by antibodies against S only. Immunization with the N protein recombinant had no apparent effect on the outcome of challenge. However, three of eight kittens immunized with the M protein recombinant survived the challenge, as compared to one of eight kittens of the control group.

    Pneumothorax is a complication that rarely occurs after chemotherapy for lung cancer. We report the chest computed tomography findings of a case of spontaneous pneumothorax complicating docetaxel (Taxotere®) treatment for pulmonary metastasis in a 70-year-old woman with pulmonary adenocarcinoma. The patient developed bilateral pneumothoraces, which was induced by changes in the cavitary pulmonary metastatic lesions, after systemic chemotherapy with docetaxel. The chest computed tomography findings and possible mechanisms of this unusual complication are discussed in this report. PMID:23820551

    An 'epidemic' of aseptic peritonitis occurred in our peritoneal dialysis unit, affecting 5 of 20 patients. Acute and convalescent viral titers were normal in all 5. The peritoneal fluid of the affected patients was not tested for endotoxin, but endotoxin was found in subsequent dialysis fluids from two machines in the unit. This endotoxin might have been the causative agent of this outbreak. Rapid recovery ensued in all patients following peritoneal lavage. PMID:503270

    Peritoneal fibrosis (PF) is invariably observed in patients undergoing long-term peritoneal dialysis (PD). The condition is thought to occur in response to a variety of insults, including bioincompatible dialysates (acidic solution, high glucose, glucose degradation products, or a combination), peritonitis, uremia, and chronic inflammation. Recently, the pathophysiologic mechanisms that contribute to the fibrosing process have been intensively studied. Transforming growth factor-beta has been shown to be a key mediator of PF. Loss of the mesothelial cell layer has been identified in several studies and shown to correlate with submesothelial thickening and vasculopathy. An association has also been identified between increased submesothelial thickness in the peritoneal membrane and increased solute transport, suggesting a relationship between PF and loss of ultrafiltration capacity. Thus, to maintain long-term PD and improve quality of life for patients, it is important to develop interventions for prevention and treatment of PF. Several strategies for peritoneal fibrosis intervention have been reported, including developing biocompatible dialysate, targeting mediators responsible for inflammation and fibrosis, and reconstituting the peritoneum using mesothelial or bone marrow-derived cells. Recent experimental trials in animal models and clinical studies are presented in this review.

    This case report describes a Mullerian serous adenocarcinoma arising within a multoloculated cyst lined by ciliated serous-type epithelium located in the sigmoid mesentery. Twenty years previously the patient underwent a hysterectomy, bilateral salpingo-oophorectomy, and omentectomy. The ovaries contained bilateral serous cystadenofibromas, and multiple cysts lined by ciliated serous-type epithelium were present in the omentum. The resection specimen 20 years later contained a 14 cm multiloculated cyst located in the sigmoid mesentery. This was lined largely by benign ciliated serous-type epithelium but a focus of well differentiated serous adenocarcinoma projected into the lumen. Two further peritoneal cysts were present, both of which were lined by ciliated serous-type epithelium. There was a coincidental renal cell carcinoma. This is a unique case of multiple omental, peritoneal, and retroperitoneal cysts (classified as cystic endosalpingiosis), one of which developed a focus of serous adenocarcinoma. Although rarely serous adenocarcinomas, similar to those occurring within the ovary, arise in the retroperitoneum, this is the first reported occurrence in association with a pre-existing benign lesion.

    A prospective study was done to evaluate the incidence and microbiological trend of peritoneal infection in patients undergoing acute intermittent peritoneal dialysis (PD). Complete sterile procedure was ensured and at the completion of the procedure PD fluid was sent for bacteriological culture, sensitivity, and total and differential cell count. During the period September 2000 to February 2001 a total of 100 patients were evaluated. Male female ratio was 72:28. Mean age was 43.17 +/- 17.2 years. In 26 patients cyclers were used. Bacterial culture was positive in total of 30 cases (30%). Gram positive, Gram negative and mixed infection was found in 10%, 15%, and 5% respectively. Number of exchanges (31.61 +/- 7.7 vs. 31.3 +/- 6, p = 0.8) were similar and number of repositioning was significantly more in the infected group (23.3% vs. 11.4%, p < 0.01). Total cell count was significantly higher in infected group (274.3 +/- 502 vs. 31.25 +/- 79.34, p < 0.01). Among Gram +ve organisms Staphylococcus was found in 7, Enterococcus faecalis in 4 and Coryne bacterium sps. in 2 cases. Among Gram -ve organisms, E. coli was found in 4, Enterobacter in 3, Klebsiella 1, Pseudomonas 1, Acinetobacter arinatus 5, Acinetobacter baumani 3, and Citrobacter freundii 3. Mixed flora comprised of Enterococcus faecalis 3, Enterobacter 1, Staphlococcus 1, E. coli 3, Citrobacter 1, Acinobacter baumani 1. Although with the cyclers using collapsible bags, staphylococcus was not isolated, the total incidence of infection (11/26 cases) was not decreased with the use of cyclers. We conclude that in acute intermittent peritoneal dialysis the incidence of bacterial infection is 30% with preponderance of Gram -ve over Gram +ve organisms and organism of fecal origin being commoner than those of skin origin. Use of cycler-assisted over manual PD do not improve the incidence of infection. Repositioning of the stiff catheter significantly increases the incidence of infection.

    Breast metastases from non-mammary cancers are rare, especially when they appear synchronously. Clinically, it is vitally important to accurately diagnose these patients, as this will directly influence their treatment and survival. We present a very rare and complex case of bilateral breast adenocarcinomas with an EML4–ALK fusion, which was diagnosed as bilateral breast metastases of non-small-cell lung cancer by immunohistochemistry and comprehensive genomic investigation. The patient was successfully treated with an ALK inhibitor (crizotinib); symptoms improved quickly after initiation of crizotinib therapy, and a partial response was observed after 3 months. The experience of diagnosis and treatment of this case indicates the importance and necessity of genomic investigations in such patients, and suggests that we need to consider the rare possibility of this kind of metastasis in order to provide optimal treatment.

  5. Molecular mechanisms of peritoneal dissemination in gastric cancer

    2016-01-01

    Peritoneal dissemination represents a devastating form of gastric cancer (GC) progression with a dismal prognosis. There is no effective therapy for this condition. The 5-year survival rate of patients with peritoneal dissemination is 2%, even including patients with only microscopic free cancer cells without macroscopic peritoneal nodules. The mechanism of peritoneal dissemination of GC involves several steps: detachment of cancer cells from the primary tumor, survival in the free abdominal cavity, attachment to the distant peritoneum, invasion into the subperitoneal space and proliferation with angiogenesis. These steps are not mutually exclusive, and combinations of different molecular mechanisms can occur in each process of peritoneal dissemination. A comprehensive understanding of the molecular events involved in peritoneal dissemination is important and should be systematically pursued. It is crucial to identify novel strategies for the prevention of this condition and for identification of markers of prognosis and the development of molecular-targeted therapies. In this review, we provide an overview of recently published articles addressing the molecular mechanisms of peritoneal dissemination of GC to provide an update on what is currently known in this field and to propose novel promising candidates for use in diagnosis and as therapeutic targets.

    Colorectal cancer (CRC) is the third most common cancer and the fourth most common cause of cancer-related death worldwide. Besides the lymphatic and haematogenous routes of dissemination, CRC frequently gives rise to transcoelomic spread of tumor cells in the peritoneal cavity, which ultimately leads to peritoneal carcinomatosis (PC). PC is associated with a poor prognosis and bad quality of life for these patients in their terminal stages of disease. A loco-regional treatment modality for PC combining cytoreductive surgery and hyperthermic intraperitoneal peroperative chemotherapy has resulted in promising clinical results. However, this novel approach is associated with significant morbidity and mortality. A comprehensive understanding of the molecular events involved in peritoneal disease spread is paramount in avoiding unnecessary toxicity. The emergence of PC is the result of a molecular crosstalk between cancer cells and host elements, involving several well-defined steps, together known as the peritoneal metastatic cascade. Individual or clumps of tumor cells detach from the primary tumor, gain access to the peritoneal cavity and become susceptible to the regular peritoneal transport. They attach to the distant peritoneum, subsequently invade the subperitoneal space, where angiogenesis sustains proliferation and enables further metastatic growth. These molecular events are not isolated events but rather a continuous and interdependent process. In this manuscript, we review current data regarding the molecular mechanisms underlying the development of colorectal PC, with a special focus on the peritoneum and the role of the surgeon in peritoneal disease spread.

    Questions have been raised about the safety of diagnostic hysteroscopy preceding surgical treatment of endometrial carcinoma. Several studies showed that the risk of a positive cytology among patients presenting endometrial adenocarcinoma was increased after diagnostic hysteroscopy, suggesting a peritoneal dissemination of tumor cells due to the exploration. We studied this hypothesis on the basis of a systematic review of the scientific data. Five studies fulfilling inclusion criteria have been selected and have been introduced into a fixed model of meta-analysis. On a total of 756 studied patients, 79 presented a positive peritoneal cytology. The diagnostic hysteroscopy did not increase significantly the risk of abdominal dissemination of tumor cells, the peritoneal cytology being positive among 38 patients in the group having undergone this intervention vs 41 patients in the control group (OR = 1,64; 95% CI: 0,96-2,80). In conclusion, no formal evidence is currently available concerning the role of diagnostic hysteroscopy on the frequency of peritoneal dissemination of tumor cells, or on the vital prognosis of the patients presenting with endometrial carcinoma. From the data available, there is not any reason to avoid diagnostic hysteroscopy in the initial workup of endometrial cancer. PMID:15894211

    BACKGROUND: Extrapulmonary tuberculosis has vague symptoms and few signs. It is essential to recognize and diagnose this curable disease prior to performing definitive surgery. Newer tests such as DNA or RNA amplification allow for early diagnosis but have limitations. CASE: We report a case of peritoneal tuberculosis in an immigrant woman. She had vague symptoms of low-grade fever, mild abdominal pain, obstipation, and bloating. Diagnostic laparoscopy was performed to establish the diagnosis. Tuberculosis was confirmed by DNA extraction from the frozen section specimen with subsequent analysis using polymerase chain reaction. CONCLUSION: Peritoneal tuberculosis is a disease that often simulates malignancies. With the increasing prevalence of human immunodeficiency virus in developed countries, tuberculosis is also on the rise and should be considered in the differential diagnosis of a patient with an abdominal/pelvic mass and ascites.

    While Mexico has the thirteenth largest economy, a large portion of the population is impoverished. About 90% of the population is Mestizo, the result of the admixture of Mexican Indians and Spaniards, with the Indigenous peoples concentrated in the southeastern region. Treatment for end-stage renal disease (estimated 268 patients per million population) is largely determined by the limited healthcare system and the individual's access to resources such as private insurance ( approximately 15%) and governmental sources ( approximately 85%). With only 5% of the gross national product spent on healthcare and most treatment providers being public health institutions that are often under severe economic restrictions, it is not surprising that many Mexican patients do not receive renal replacement therapy. Mexico uses proportionately more peritoneal dialysis than other countries; 1% of the patients are on automated peritoneal dialysis, 19% on hemodialysis and 80% on CAPD. Malnutrition and diabetes, important risk factors for poor outcome, are prevalent among the patients in CAPD programs.

    With the current rise in multiresistant gram-negative bacteria, carbapenems are more frequently used. Surprisingly, limited data exist on the pharmacokinetics of meropenem in peritoneal dialysis (PD)-related peritonitis. We report on the pharmacokinetics of repeated intraperitoneal (IP) meropenem during 21 days as treatment for polymicrobial multiresistent PD-related peritonitis.Our current report supports daily doses of 125 mg/L intraperitoneal meropenem in all bags as an effective and safe modality in the treatment of PD-associated peritonitis with multiresistant microorganisms. No signs of over- or underdosing were found based on serial drug concentration measurements at fixed time points up to 21 days. PMID:27659932

    Sclerosing encapsulating peritonitis (SEP) is a rare chronic inflammatory condition of the peritoneum with an unknown aetiology. Also known as abdominal cocoon, the condition occurs when loops of the bowel are encased within the peritoneal cavity by a membrane, leading to intestinal obstruction. Due to its rarity and non-specific clinical features, it is often misdiagnosed. The condition presents with recurrent episodes of small bowel obstruction and can be idiopathic or secondary; the latter is associated with predisposing factors such as peritoneal dialysis or abdominal tuberculosis. In the early stages, patients can be managed conservatively; however, surgical intervention is necessary for those with advanced stage intestinal obstruction. A literature review revealed 118 cases of SEP; the mean age of these patients was 39 years and 68.0% were male. The predominant presentation was abdominal pain (72.0%), distension (44.9%) or a mass (30.5%). Almost all of the patients underwent surgical excision (99.2%) without postoperative complications (88.1%). PMID:27226904

    Objective To define the maximum tolerated dose (MTD) and assess the feasibility of intravenous (IV) paclitaxel, intraperitoneal (IP) carboplatin, and IP paclitaxel in women with newly diagnosed Stages II–IV ovarian, fallopian tube, or primary peritoneal carcinoma. Methods Patients received escalating doses of paclitaxel IV and carboplatin IP on day 1 and paclitaxel IP 60 mg/m2 on day 8. A standard 3+3 design was used in the escalation phase. A two-stage group sequential design with 20 patients at the MTD was used in the feasibility phase. Patient-reported neurotoxicity was assessed pre and post treatment. Results Patients were treated with paclitaxel 175 mg/m2 IV and carboplatin IP from AUC 5–7 on day 1 and paclitaxel 60 mg/m2 IP on day 8. The MTD was estimated at carboplatin AUC 6 IP and 25 patients enrolled at this dose level. Within the first 4 cycles, seven (35%) of twenty evaluable patients had dose-limiting toxicities (DLTs) including grade 4 thrombocytopenia (1), grade 3 neutropenic fever (3), >2 week delay due to ANC recovery (1), grade 3 LFT (1), and grade 3 infection (1). De-escalation to paclitaxel 135 mg/m2 IV was given to improve the safety. After six evaluable patients completed 4 cycles without a DLT, bevacizumab was added and six evaluable patients completed 4 cycles with one DLT (grade 3 hyponatremia). Conclusions Paclitaxel at 175 mg/m2 IV, carboplatin AUC 6 IP day 1 and paclitaxel 60 mg/m2 IP day 8 yield 18–56% patients with DLTs. The tolerability of the regimen in combination with bevacizumab was indicated in a small cohort. PMID:22155262

Methods Patients received docetaxel (55-75 mg/m2) IV and carboplatin (AUC 5-7) IP on day 1 and paclitaxel 60 mg/m2 IP on day 8. A standard 3+3 design was used in the dose escalation phase. A 2-stage group sequential design with 20 patients at the MTD was used in the feasibility phase. Results The MTD determined during the dose escalation phase was day 1 docetaxel 75 mg/m2 IV, carboplatin AUC 6 IP and day 8 IP paclitaxel 60 mg/m2. Forty-six patients were enrolled in the feasibility portion at this dose level. Six were unevaluable. Fifteen evaluable patients had dose-limiting toxicities (DLTs) within the first four cycles. These DLTs were prolonged neutropenia (2), neutropenic fever (7), grade 4 thrombocytopenia (1), grade 4 dehydration (1), grade 3 infection (2), grade 3 oral mucositis (1) and pulmonary embolism (1). Conclusions Docetaxel 75 mg/m2 IV, carboplatin AUC 6 IP administered on day 1, and paclitaxel 60 mg/m2 IP administered on day 8, is the MTD when considering one cycle of treatment but was not feasible over four cycles due to bone marrow toxicity. We recommend reduction of carboplatin to AUC 5 should this regimen be considered for treatment in women with newly diagnosed advanced ovarian cancer. PMID:22943879

    Primary adenocarcinoma of the urinary bladder is a rare disease. It occurs in 0.5–2% of all bladder cancers and is discussed as the malignant counterpart of nephrogenic adenomas. We report a 46-year-old white female presented with gross hematuria for clinical examination. Histopathology revealed pT2, Pn1, L1, G2 adenocarcinoma of the bladder and carcinoma in situ according to the TNM classification. Computed tomography scan diagnostic was unremarkable. Patients with adenocarcinoma of the urinary bladder should be treated vigorously and without time delay. Only 7 cases of adenocarcinoma in the urinary bladder (mesonephroid) have been described until now. We present a case of clear cell adenocarcinoma of the urinary bladder, mesonephroid type that early diagnosed and till now 3 months after the cystectomy without symptoms and without complications.

    The current paradigm concerning the mechanism of peritoneal dissemination of gastric cancer is that it occurs through an invasive process in which cancer cells directly penetrate the gastric wall and exfoliate into the peritoneal cavity. However, some experimental studies suggest the lymphatic route as an alternative. We present five early gastric cancer cases, which support this alternative pathway of peritoneal dissemination without direct invasion in the serosa. We investigated all patients with early gastric cancer who underwent curative gastrectomy between September 2002 and February 2015 at the Shizuoka Cancer Center, Japan. We examined them by intraoperative peritoneal lavage cytology and frozen section diagnosis of peritoneal nodules during laparotomy. Peritoneal dissemination was defined as peritoneal metastasis by positive cytology or histological diagnosis. Among 1509 early gastric cancers, five cases (0.3 %, 95 % CI 0.1-0.8 %) presented peritoneal dissemination detected by lavage cytology and frozen section diagnosis of peritoneal nodules. Histological examination revealed that the primary tumors invaded the submucosal layer using the lymphatic route, through which they metastasized to regional lymph nodes. Our data indicate that gastric cancer may give rise to peritoneal dissemination even at an early stage, probably through the lymphatic route without direct invasion into the serosa.

FIP causes many problems to the veterinarian as it can be difficult to definitively diagnose the disease, as there is no effective treatment, and as prophylactic interventions are not very successful. Although intense research has created a lot of new knowledge about this disease in the last years, there are still many unanswered questions. The objective of this article is to review recent knowledge and to increase understanding of the complex pathogenesis of FIP.

    Feline infectious peritonitis (FIP) frequently results in death in cats. It is caused by a mutated, highly contagious coronavirus, and it is more common in indoor cats in multicat households. A complex interaction between the coronavirus and the feline immune system causes disseminated vasculitis, which is the hallmark of FIP. New tests are being developed, but the antemortem diagnosis of FIP continues to be difficult and frustrating. Current treatments are crude and involve supportive care and immunosuppression. Minimizing exposure is the best method of preventing infection.

    Feline infectious peritonitis is a noncurable viral disease affecting cats worldwide. Recent evidence suggests that the FIPV has evolved as a deletion mutation of FECV. Immune complex deposition and vasculitis with pyogranulomatous lesions are the hallmark of FIP. The only definitive antemortem diagnostic test for FIP is histopathologic examination of tissue. Ocular manifestations occur commonly with noneffusive FIP. The most common clinical sign is a bilateral granulomatous anterior uveitis often accompanied by chorioretinitis. Treatment of ocular FIP is symptomatic, and the mainstay of palliative therapy is topical or systemic corticosteroids or both.

    Leiomyomatosis peritonealis disseminata is a very rare condition characterized by the development of multiple smooth muscle-like nodules in the peritoneal cavity. It is associated with increased serum levels of gonadal steroids. The present report describes a 29-year-old patient underwent transabdominal hysterectomy and Bilateral Salpingo oophorectomy six years ago because of leiomyomatosis peritonealis disseminata. After six years she referred to us again because of retroperitoneal fibroma, another rare entity, during hormone replacement therapy inspite of lack of uterus and previous castration. PMID:23365481

    Pseudomyxoma peritonei (PMP) is a complex disease with unique biological behavior that usually arises from appendiceal mucinous neoplasia. The classification of PMP and its primary appendiceal neoplasia is contentious, and an international modified Delphi consensus process was instigated to address terminology and definitions. A classification of mucinous appendiceal neoplasia was developed, and it was agreed that "mucinous adenocarcinoma" should be reserved for lesions with infiltrative invasion. The term "low-grade appendiceal mucinous neoplasm" was supported and it was agreed that "cystadenoma" should no longer be recommended. A new term of "high-grade appendiceal mucinous neoplasm" was proposed for lesions without infiltrative invasion but with high-grade cytologic atypia. Serrated polyp with or without dysplasia was preferred for tumors with serrated features confined to the mucosa with an intact muscularis mucosae. Consensus was achieved on the pathologic classification of PMP, defined as the intraperitoneal accumulation of mucus due to mucinous neoplasia characterized by the redistribution phenomenon. Three categories of PMP were agreed-low grade, high grade, and high grade with signet ring cells. Acellular mucin should be classified separately. It was agreed that low-grade and high-grade mucinous carcinoma peritonei should be considered synonymous with disseminated peritoneal adenomucinosis and peritoneal mucinous carcinomatosis, respectively. A checklist for the pathologic reporting of PMP and appendiceal mucinous neoplasms was also developed. By adopting the classifications and definitions that were agreed, different centers will be able to use uniform terminology that will allow meaningful comparison of their results.

    Rhizobium radiobacter (Agrobacterium radiobacter) is an aerobic Gram-negative rod belonging to Agrobacterium genus, a group of phytopathogenic bacteria present in the soil that has been implicated in human opportunistic infections. We report a clinical case of bacterial peritonitis in a 5-year-old child with chronic renal disease in peritoneal dialysis, who had a history of direct soil contact identified. The infection was treated with ceftazidime and piperaciline+tazobactam without relapses or the need to remove the peritoneal dialysis catheter.

    We present a 13-year-old girl with Arnold-Chiari syndrome and uremia secondary to neurogenic bladder. She had been treated with continuous ambulatory peritoneal dialysis (CAPD) for 13 months prior to the development of peritonitis. The patient demonstrated no improvement with a 3-day therapy of intraperitoneal vancomycin and netilmicin. Meanwhile, smear of centrifuged dialysate revealed acid fast bacilli on two occasions. We, then, started anti-TB therapy with oral isoniazid (INAH), rifampin and ethambutal. The symptoms subsided within three days. In the first week, the patient lost her peritoneal ultrafiltration and needed daytime automatic peritoneal dialysis. At the last follow-up examination, 12 months after treatment, she remained well on standard CAPD.

    The socioeconomic status of Asian countries is diverse, and government reimbursement policies for treatment of patients suffering from end-stage renal disease (ESRD) vary greatly from one country to another. Both of these factors have a major impact not only on the choice of treatment for ESRD but also on the utilization of peritoneal dialysis (PD) in this region. Based on the data collected from 11 representative Asian countries, several observations can be made. First, the treatment rates for ESRD in these countries correlated closely with their gross domestic product (GDP) per capita income. Second, the PD utilization rate appeared to have a biphasic relationship with the GDP per capita income and treatment rate, in that countries with the highest and the lowest treatment rates tended to have lower PD utilization rates, whereas countries with modest treatment rates tended to have higher PD utilization rates. The reason for low PD utilization in countries with the highest treatment rates differs from that in countries with low treatment rates. In the former, because of full government reimbursement, there is little physician incentive to introduce PD as an alternative form of ESRD treatment to in-center hemodialysis (HD), whereas in the latter, the complete lack of government reimbursement prevents the introduction of PD as a form of treatment. This pattern is likely to change in the future because, of the 11 countries surveyed, all except Thailand have recorded a growth rate which is higher for PD than HD over the last three years. The rate of utilization of different PD systems varies greatly among different Asian countries. Automated PD has yet to gain popularity in Asia. Conventional straight-line systems remain the dominant PD systems in use in Hong Kong, Korea, Thailand, and the Philippines, while in Malaysia and Singapore UV germicidal connection devices are most popular. However, in all these countries there has been a progressive shift over the last

    The swan neck presternal catheter is composed of 2 flexible (silicon rubber) tubes joined by a titanium connector at the time of implantation. The exit site is located in the parasternal area. The catheter located on the chest was designed to reduce the incidence of exit site infections compared to peritoneal dialysis catheters with abdominal exits. From August 1991 to September 30, 2001, 974 swan neck presternal catheters were implanted worldwide. At the university of Missouri, 150 of these catheters were implanted and followed for over 130 patient years. Presternal catheters tended to perform better than swan neck abdominal catheters regarding exit and tunnel infections, even though they were implanted in several patients in whom regular catheters with the exit on the abdomen would be difficult or impossible to implant. Two-year survival probability of presternal catheters was 0.95. Recurrent/refractory peritonitis was the only reason for catheter failure. The catheter is particularly useful in obese patients (body mass index >35), patients with ostomies, children with diapers and fecal incontinence, and patients who want to take baths without the risk of exit contamination. Many patients prefer presternal catheter because of better body image. Disadvantages of the presternal catheter are minimal. Compared with abdominal catheters, dialysis-solution flow is slightly slower because of the increased catheter length; however, slower flow is insignificant clinically. There is a possibility of catheter disconnection in the tunnel, but this complication is extremely rare in adults and easily corrected. Finally, the implantation technique is more challenging compared with that of single-piece, abdominal catheters. PMID:12085389

    Peritoneal dialysis (PD) is associated with structural and functional alterations of the peritoneal membrane, consisting of fibrosis, angiogenesis, and loss of ultrafiltration capacity. Vitamin D receptor activation (VDRA) plays an important role in mineral metabolism and inflammation, but also antiangiogenic and antifibrotic properties have been reported. Therefore, the effects of active vitamin D treatment on peritoneal function and remodeling were investigated. Rats were either kept naïve to PDF exposure or daily exposed to 10 mL PDF and were treated for five or seven weeks with oral paricalcitol or vehicle control. Non-PDF-exposed rats showed no peritoneal changes upon paricalcitol treatment. Paricalcitol reduced endogenous calcitriol but did not affect mineral homeostasis. However, upon PDF exposure, loss of ultrafiltration capacity ensued which was fully rescued by paricalcitol treatment. Furthermore, PD-induced ECM thickening was significantly reduced and omental PD-induced angiogenesis was less pronounced upon paricalcitol treatment. No effect of paricalcitol treatment on total amount of peritoneal cells, peritoneal leukocyte composition, and epithelial to mesenchymal transition (EMT) was observed. Our data indicates that oral VDRA reduces tissue remodeling during chronic experimental PD and prevents loss of ultrafiltration capacity. Therefore, VDRA is potentially relevant in the prevention of treatment technique failure in PD patients. PMID:26605330

    Bordetella bronchiseptica is a rare cause of invasive human infection. The most common infection in humans is the respiratory tract infection and it is usually associated with immunosuppression, particularly acquired immunodeficiency syndrome (AIDS). We report a case of a pneumonia and peritonitis in a 42-year-old female with alcoholic liver disease. The patient died despite treatment with antibiotics. This case illustrates the potential virulence of B. bronchiseptica in susceptible patients and to our knowledge it is the first case of primary peritonitis due to this organism.

    Uraemia and long-term peritoneal dialysis (PD) can lead to fibrotic thickening of the peritoneal membrane, which may limit its dialytic function. Peritoneal fibrosis is associated with the appearance of myofibroblasts and expansion of extracellular matrix. The extent of contribution of resident peritoneal fibroblasts to these changes is a matter of debate. Recent studies point to a significant heterogeneity and complexity of the peritoneal fibroblast population. Here, we review recent developments in peritoneal fibroblast biology and summarize the current knowledge on the involvement of peritoneal fibroblasts in peritoneal inflammation and fibrosis.

    Epithelial ovarian cancer (EOC) is the leading cause of death from gynecologic malignancy in the United States. Mortality is due to diagnosis of 75% of women with late stage disease, when metastasis is already present. EOC is characterized by diffuse and widely disseminated intra-peritoneal metastasis. Cells shed from the primary tumor anchor in the mesothelium that lines the peritoneal cavity as well as in the omentum, resulting in multi-focal metastasis, often in the presence of peritoneal ascites. Efforts in our laboratory are directed at a more detailed understanding of factors that regulate EOC metastatic success. However, quantifying metastatic tumor burden represents a significant technical challenge due to the large number, small size and broad distribution of lesions throughout the peritoneum. Herein we describe a method for analysis of EOC metastasis using cells labeled with red fluorescent protein (RFP) coupled with in vivo multispectral imaging. Following intra-peritoneal injection of RFP-labelled tumor cells, mice are imaged weekly until time of sacrifice. At this time, the peritoneal cavity is surgically exposed and organs are imaged in situ. Dissected organs are then placed on a labeled transparent template and imaged ex vivo. Removal of tissue auto-fluorescence during image processing using multispectral unmixing enables accurate quantitation of relative tumor burden. This method has utility in a variety of applications including therapeutic studies to evaluate compounds that may inhibit metastasis and thereby improve overall survival. PMID:27500635

    PURPOSE We encountered a case where an infection with group A streptococcus (GAS; ie, Streptococcus pyogenes) initially caused primary peritonitis and then subsequently caused streptococcal toxic shock syndrome. The patient’s life was likely saved by an emergency laparotomy followed by extensive peritoneal lavage and drainage. CASE PRESENTATION A 40-year-old woman was admitted to the Emergency Department for lower abdominal pain and numbness in the extremities. She presented with systemic inflammatory response syndrome. An emergency laparotomy was performed, and ascites that resembled pus and general peritonitis were noted. Peritoneal lavage and drainage were performed, and GAS was isolated from peritoneal fluid. Gram staining of cervical polyp specimens revealed Gram-positive bacteria. CONCLUSIONS The patient was diagnosed with streptococcal toxic shock syndrome due to an ascending GAS infection originating from vagina. PMID:27579001

    concentration of triglycerides and triglyceride-rich complex lipoproteins. There are indications that dialytic variables may influence this development. When peritoneal function was assessed by the Peritoneal Dialysis Capacity test at start of dialysis, it was observed that peritoneal function reflected patient characteristics and co-morbidity. Patients with systemic disease had enhanced diffusion capacity compared to patients with primary renal disorders. Furthermore, in patients with more severe co-morbidity. peritoneal protein losses were increased. Finally, elderly patients had ultrafiltration conditions that were different from those of younger patients. Peritoneal function remained essentially stable during medium-long term follow up. Body composition features in dialysis patients are similar to those seen in severe disease in general. Thus, it is difficult to separate the effects of malnutrition from the effects of the underlying disease. Specific standards for nutritional status adapted for patients with renal failure are required.

    This paper describes an experimental model of peritoneal adhesions, in the rat, based on two relatively minor accidents that may occur during abdominal surgery in man: drying of the serosa, and bleeding. Drying alone had little effect; drying plus bleeding consistently produced adhesions to the dried area. Fresh blood alone produced adhesions between the three membranous structures [omentum and pelvic fat bodies (PFBs)]. The formation of persistent adhesions required whole blood. Preformed clots above a critical size induced adhesions even without previous serosal injury; they were usually captured by the omentum and PFBs. If all three membranous structures were excised, the clots caused visceral adhesions. The protective role of the omentum, its structure, and the mechanism of omental adhesions, are discussed. These findings are relevant to the pathogenesis of post-operative adhesions in man. ImagesFig 3Fig 4Fig 5Fig 6Fig 7Fig 12Fig 13Fig 1Fig 2Fig 14Fig 15Fig 8Fig 9Fig 10Fig 11 PMID:5315369

    Fibrosis of the peritoneal cavity remains a serious, life-threatening problem in the treatment of kidney failure with peritoneal dialysis. The mechanism of fibrosis remains unclear partly because the fibrogenic cells have not been identified with certainty. Recent studies have proposed mesothelial cells to be an important source of myofibroblasts through the epithelial–mesenchymal transition; however, confirmatory studies in vivo are lacking. Here, we show by inducible genetic fate mapping that type I collagen–producing submesothelial fibroblasts are specific progenitors of α-smooth muscle actin–positive myofibroblasts that accumulate progressively in models of peritoneal fibrosis induced by sodium hypochlorite, hyperglycemic dialysis solutions, or TGF-β1. Similar genetic mapping of Wilms’ tumor-1–positive mesothelial cells indicated that peritoneal membrane disruption is repaired and replaced by surviving mesothelial cells in peritoneal injury, and not by submesothelial fibroblasts. Although primary cultures of mesothelial cells or submesothelial fibroblasts each expressed α-smooth muscle actin under the influence of TGF-β1, only submesothelial fibroblasts expressed α-smooth muscle actin after induction of peritoneal fibrosis in mice. Furthermore, pharmacologic inhibition of the PDGF receptor, which is expressed by submesothelial fibroblasts but not mesothelial cells, attenuated the peritoneal fibrosis but not the remesothelialization induced by hypochlorite. Thus, our data identify distinctive fates for injured mesothelial cells and submesothelial fibroblasts during peritoneal injury and fibrosis. PMID:24854266

    With the present study the authors set themselves the task to compare the number of peritonitis episodes in patients treated with two types of systems: "Sorin-Biomedica" and "Travenol-(UV-XD)", in which disinfection of the connecting devices is achieved accordingly with chemical agents and with ultraviolet irradiation. Eleven patients have been observed from August 1984 through February 1989. The total duration of treatment was 156 months. Twenty one peritonitis episodes were observed--15 with "Sorin-Biomedica" system and 6 with "Travenol-(UV-XD)" system--an average of one episode in 4 1/2 months with the former system and one episode in 14.7 months with the latter. It is pointed out in conclusion that the "Travenol-(UV-XD)" system with ultraviolet disinfection has significantly reduced the incidence of peritonitis at the dialysis center where the authors work.

  6. Water channels in peritoneal dialysis.

    PubMed

    Devuyst, Olivier

    2010-01-01

    Peritoneal dialysis involves diffusive and convective transports and osmosis through the highly vascularized peritoneal membrane. Several lines of evidence have demonstrated that the water channel aquaporin-1 (AQP1) corresponds to the ultrasmall pore predicted by the modelization of peritoneal transport. Proof-of-principle studies have shown that up-regulation of the expression of AQP1 in peritoneal capillaries is reflected by increased water permeability and ultrafiltration, without affecting the osmotic gradient and the permeability for small solutes. Inversely, studies in Aqp1 mice have shown that haploinsufficiency in AQP1 is reflected by significant attenuation of water transport. Recent studies have identified lead compounds that could act as agonists of aquaporins, as well as putative binding sites and potential mechanisms of gating the water channel. By modulating water transport, these pharmacological agents could have clinically relevant effects in targeting specific tissues or disease states. These studies on the peritoneal membrane also provide an experimental framework to investigate the role of water channels in the endothelium and various cell types.

    Introduction: Complications within laparoscopic surgery, similar to classic surgery are inevitable and require immediate actions both to diminish intraoperative risks and to choose the appropriate therapeutic attitude. Peritonitis and hemorrhagic incidents are both part of the complications aspect of laparoscopic surgery. Fortunately, the incidence is limited, thus excluding the rejection of celioscopic methods. Patient’s risks and benefits are to be analyzed carefully prior recommending laparoscopic surgery. Materials and methods: This study presents a statistical analysis of peritonitis consecutive to laparoscopic surgery, experience of „Sf. Ioan” Emergency Hospital, Bucharest, and Department of Surgery (2000-2010). Results:There were 180 (0,96%) complicated situations requiring reinterventions, from a total of 18676 laparoscopic procedures. 106 cases (0,56%) represented different grades of postoperative peritonitis. Most frequently, there were consecutive laparoscopic appendicectomia and colecistectomia. During the last decade, few severe cases of peritonitis followed laparoscopic bariatric surgical procedures. Conclusions: This study reflects the possibility of unfavorable evolution of postoperative peritonitis comparing with hemorrhagic incidents within laparoscopic surgery. PMID:23049630

    Tuberculous peritonitis is a common form of abdominal tuberculosis and is frequently associated with liver disease. Diagnosis of this disease presents a diagnostic dilemma and the presence of liver cirrhosis further confounds the clinical picture. Moreover, the co-existence of these two diseases casts doubt on the validity of various diagnostic tests available. The interpretation of tests of ascitic fluid analysis becomes questionable despite the fact that peritoneal tuberculosis and liver disease cause ascites to develop through separate mechanisms. In addition, the treatment of tuberculosis mandates a better understanding of the co-existent disease in view of the potential hepatotoxicity of anti-tuberculous medication. This review aims to address the prevalence of coexistent liver disease in patients with tuberculous peritonitis, the diagnostic difficulties posed by such and the various treatment approaches to be adopted.

    An integrated treatment strategy using peritonectomy procedures plus hyperthermic intraperitoneal chemotherapy (HIPEC) is now a clinical standard of care in selected patients with peritoneal metastases and primary peritoneal tumors. This comprehensive approach can offer many patients, who hitherto had no hope of cure, a good quality of life and survival despite limited morbidity. The increasingly successful results and chance of interfering in the natural history of disease has prompted research to develop for some clinical conditions a therapeutic strategy designed to prevent malignant peritoneal dissemination before it becomes clinically evident and treat it microscopically (tertiary prevention). The main factor governing successful cytoreductive surgery and predicting outcome is the extent of peritoneal spread assessed with the peritoneal cancer index (PCI). In peritoneal metastases from colorectal and gastric cancer the PCI score acquires a specific role acting as the cut-off between patients who can undergo curative surgery or palliation. Long-term results show that the only group enjoying favorable results are patients with limited disease (a statistical minority). By applying to appropriately selected patients with primary malignancies a proactive management strategy including HIPEC we can treat patients with microscopic peritoneal dissemination and therefore at PCI 0. Among treated conditions pseudomyxoma peritonei enjoys the best results. But a major future advance comes from identifying among lesions at major risk of pseudomyxoma. PMID:27065712

    The causes were studied and the analysis was performed of the lethality in 329 patients with acute diffuse peritonitis (ADP). The incidence of lethal outcome of ADP directly depended on the time of hospitalization, age of the patients, source of peritonitis, and as well on the technique of operative intervention. Progressive peritonitis caused death in 71 (92.2%) of 77 patients.

    Peritoneal dialysis is the renal replacement modality used by ∼20% of patients with end-stage kidney disease (S. McDonald, P. Clayton, and K. Hurst, p. 6.2-6.27, in ANZDATA 2012 Annual Report, 35th ed., 2012). A major complication of peritoneal dialysis is the development of peritonitis. We describe a case of Humicola sp. causing peritoneal dialysis (PD)-associated peritonitis, successfully treated with a prolonged course of antifungal therapy.

  15. Adenocarcinoma of the ethmoid following radiotherapy for bilateral retinoblastoma

    Adenocarcinoma of the ethmoid sinus is rare, representing only 4 to 8% of malignancies of the paranasal sinuses. An extraordinary case of papillary adenocarcinoma of the ethmoid sinus arising 30 years following high-dose radiotherapy for bilateral retinoblastoma is presented. Second fatal mesenchymal and epithelial primaries have been described in 8.5% of patients with bilateral retinoblastomas previously treated with radiotherapy; however, papillary adenocarcinoma arising within the paranasal sinuses has not been reported. Aggressive treatment including partial maxillectomy, radical pansinusectomy, radical neck dissection followed by regional radiotherapy and systemic chemotherapy failed to prevent the development of fatal hepatic metastases. The high incidence of second fatal primary neoplasms in patients with bilateral retinoblastomas receiving radiation suggests an innate susceptibility that may add to the risk of radiotherapy.

  16. Pancreatic adenocarcinoma: Outstanding problems

    Pancreatic adenocarcinoma remains the fourth leading cause of cancer-related death and is one of the most aggressive malignant tumors with an overall 5-year survival rate of less than 4%. Surgical resection remains the only potentially curative treatment but is only possible for 15%-20% of patients with pancreatic adenocarcinoma. About 40% of patients have locally advanced nonresectable disease. In the past, determination of pancreatic cancer resectability was made at surgical exploration. The development of modern imaging techniques has allowed preoperative staging of patients. Institutions disagree about the criteria used to classify patients. Vascular invasion in pancreatic cancers plays a very important role in determining treatment and prognosis. There is no evidence-based consensus on the optimal preoperative imaging assessment of patients with suspected pancreatic cancer and a unified definition of borderline resectable pancreatic cancer is also lacking. Thus, there is much room for improvement in all aspects of treatment for pancreatic cancer. Multi-detector computed tomography has been widely accepted as the imaging technique of choice for diagnosing and staging pancreatic cancer. With improved surgical techniques and advanced perioperative management, vascular resection and reconstruction are performed more frequently; patients thought once to be unresectable are undergoing radical surgery. However, when attempting heroic surgery, a realistic approach concerning the patient’s age and health status, probability of recovery after surgery, perioperative morbidity and mortality and life quality after tumor resection is necessary.

    1999-01-01

    At 1 month, 3 months, 6 months, and more than 6 months after healed peritonitis, we evaluated repeated peritoneal equilibration tests (PETs) for small molecules such as urea, and middle molecules such as cystatin C, beta 2-microglobulin, and alpha 1-microglobulin. We analyzed a total of 104 PETs in 21 children aged 1.7-18.6 years (median: 9.9 years). Equilibration quotients (D/P)--that is, substrate concentration in dialysis fluid (D) divided by substrate concentration in plasma (P)--were calculated after a dwell time of 4 hours. The D/P for urea did not change after healed peritonitis. In a cross-sectional study, the D/P for middle molecules showed an increase in peritoneal permeability between 3 months and 6 months after a healed peritonitis. In a consecutive follow-up of 4 patients for more than 6 months, beta 2-microglobulin and, more impressively, alpha 1-microglobulin showed a statistically significant increase in D/P (p < 0.05) 3 months after a healed peritonitis. All differences seen were completely reversible after more than 6 months, showing that peritoneal function is rather stable if peritonitis is healed. It is noteworthy that peritoneal dysfunction lasts for up to 6 months after a completely healed peritonitis. This period might be a vulnerable phase in continuation of peritoneal dialysis.

  18. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in the management of gastrointestinal cancers with peritoneal metastases: Progress toward a new standard of care.

    PubMed

    Sugarbaker, Paul H

    2016-07-01

    Peritoneal metastases from gastrointestinal cancer was, in the past, accepted as an inevitable component of the natural history of these diseases. It is a major cause of intestinal obstruction, fistula formation, and bowel perforation as the recurrent malignancy progresses to a terminal condition. Peritoneal metastases may be caused by full thickness penetration of the bowel wall by the primary cancer or by spilled cancer cells released into the peritoneal space by surgical trauma. Two new surgical technologies that have evolved to manage peritoneal metastases are cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). This combined treatment strategy uses peritonectomy procedures and visceral resections to reduce the disease in the abdomen and pelvis to a macroscopic volume. Then, HIPEC is used to preserve the complete cytoreduction by controlling the minimal residual disease. Since the extent of peritoneal metastases, as measured by the peritoneal cancer index (PCI), is crucial to a favorable outcome, prognostic indicators are used to select patients for treatment. The combined treatment may be used to prevent peritoneal metastases in gastrointestinal cancer patients having a resection of the primary malignancy. This is especially important in gastric cancer patients with serosal invasion. The combined treatment may be used synchronously with the primary cancer resection if peritoneal metastases are already apparent. The treatment is most frequently used with metachronous peritoneal metastases diagnosed in follow-up. Cure of peritoneal metastases is an option in selected patients and its knowledgeable use is progressing towards a new standard of care. PMID:27347669

    PubMed

    2015-12-01

    Spontaneous bacterial peritonitis (SBP) is a severe complication occurring in patients with cirrhosis, and is associated with high mortality. Liver transplantation should be considered after a first episode of SBP. Gram-negative bacilli are the major cause of SBP, however there is an increasing trend of Gram-positive cocci related SBP. Management includes empirical antibiotic treatment and albumin infusion. The choice of antibiotics depends on the site of acquisition (community-acquired vs nosocomial or health-care associated infection) and local resistance profile, due to the emergence of drug-resistant bacteria. Secondary prophylaxis is recommended after resolution of SBP and reduces recurrence and mortality. Primary prophylaxis in patients with low protein ascites (<15 g/L) should be restricted to patients with severe cirrhosis awaiting for liver transplantation.

    Background Peritonitis and ultrafiltration failure remain serious complications of chronic peritoneal dialysis (PD). Dysfunctional cellular stress responses aggravate peritoneal injury associated with PD fluid exposure, potentially due to peritoneal glutamine depletion. In this randomized cross-over phase I/II trial we investigated cytoprotective effects of alanyl-glutamine (AlaGln) addition to glucose-based PDF. Methods In a prospective randomized cross-over design, 20 stable PD outpatients underwent paired peritoneal equilibration tests 4 weeks apart, using conventional acidic, single chamber 3.86% glucose PD fluid, with and without 8 mM supplemental AlaGln. Heat-shock protein 72 expression was assessed in peritoneal effluent cells as surrogate parameter of cellular stress responses, complemented by metabolomics and functional immunocompetence assays. Results AlaGln restored peritoneal glutamine levels and increased the primary outcome heat-shock protein expression (effect 1.51-fold, CI 1.07–2.14; p = 0.022), without changes in peritoneal ultrafiltration, small solute transport, or biomarkers reflecting cell mass and inflammation. Further effects were glutamine-like metabolomic changes and increased ex-vivo LPS-stimulated cytokine release from healthy donor peripheral blood monocytes. In patients with a history of peritonitis (5 of 20), AlaGln supplementation decreased dialysate interleukin-8 levels. Supplemented PD fluid also attenuated inflammation and enhanced stimulated cytokine release in a mouse model of PD-associated peritonitis. Conclusion We conclude that AlaGln-supplemented, glucose-based PD fluid can restore peritoneal cellular stress responses with attenuation of sterile inflammation, and may improve peritoneal host-defense in the setting of PD.

A radiobacter and P oryzihabitans occurred simultaneously in the first episode of peritonitis, and C aquaticum, in the second episode. The patient's vocation necessitated exposure to moist soiled conditions. Both episodes responded promptly to antibiotics commonly used to treat peritonitis. Although these organisms rarely lead to loss of life and commonly are considered to be contaminants, they can cause symptomatic peritonitis and peritoneal dialysis catheter loss. A review of previous case reports is included.

    Gastric and esophageal adenocarcinomas are one of the main causes of cancer-related death worldwide. While the incidence of gastric adenocarcinoma is decreasing, the incidence of gastroesophageal junction adenocarcinoma is rising rapidly in Western countries. Considering that surgical resection is currently the major curative treatment, and that the 5-year survival rate highly depends on the pTNM stage at diagnosis, gastroesophageal adenocarcinoma management is very challenging for oncologists. Several treatment strategies are being evaluated, and among them systemic chemotherapy, to decrease recurrences and improve overall survival. The MAGIC and FNCLCC-FFCD trials showed a survival benefit of perioperative chemotherapy in patients with operable gastric and lower esophageal cancer, and these results had an impact on the European clinical practice. New strategies, including induction chemotherapy followed by preoperative chemoradiotherapy, targeted therapies in combination with perioperative chemotherapy and the new cytotoxic regimens, are currently assessed to improve current standards and help developing patient-tailored therapeutic interventions.

    Metastasis to the uterine corpus is uncommon and secondary colorectal tumours of the endometrium are rare. We describe a uterine tumour with components of both primary endometrial and metastatic colorectal carcinomata. In this case, a 72-year-old obese woman presented with a 2-week history of postmenopausal bleeding per vaginum and weight loss. She had an abdominoperineal resection 3 years previously for a Dukes stage B rectal carcinoma. A transvaginal ultrasonography showed a thickened endometrium. Histology immunophenotyping showed a CK7+, CK20+, CA125− and CEA+ colorectal metastasis (a profile consistent with her previous cancer) associated with a primary CK7+, CK20−, CA125+ and CEA− endometroid endometrial adenocarcinoma. We conclude this represents endometrial metastasis of colorectal carcinoma with coincident primary endometrial adenocarcinoma. We speculate as to whether the endometrial carcinoma arose de novo or was induced by the colorectal metastasis, or whether the primary endometrial tumour provided a fertile site for the colorectal metastasis.

    Sixteen women with adenocarcinoma of the cervical stump were treated over a 15-year period. The median survivals of 40 months for stage IB and 17 months for stages II and III were significantly worse compared with those for patients treated for cervical adenocarcinoma of the intact uterus or squamous carcinoma of the cervical stump. The poor results were due to both local and distant failure. Implications regarding tumor radiosensitivity and adjuvant therapy in these high-risk patients are discussed.

    In spite of the increasingly sophisticated diagnostic workup, detailed investigations fail to reveal a primary site of origin for about 3–5% of metastatic tumors. The most commonly reported subtype in cancer of unknown primary origin is adenocarcinoma. Signet ring cell carcinoma (SRCC) is a rare poorly differentiated aggressive subtype of adenocarcinoma that most commonly arise from the gastrointestinal tract. It usually presents late and is associated with poor prognosis. Treatment options remain limited to anecdotal reports. However, immunohistochemical studies can be useful in suggesting an origin and therefore may help guide investigations and treatment options. Here we present an unusual case of metastatic SRCC of unknown primary origin presenting as peritoneal carcinomatosis in a 73-year-old man. We also review the literature on metastatic SRCC of unknown primary origin and discuss the relevant findings. This work highlights the importance of collaboration between clinicians and pathologists as well as detailed histopathological, immunohistochemical, and molecular analyses which can help guide investigations and management options.

    Peritoneal dialysis (PD) program was established in Farwaniya Hospital Kidney Center, Kuwait, in February 2011. Patient recruitment for this modality of treatment was growing steadily. One of the major complications of PD is peritonitis. There is a belief that PD therapy is inferior and carries more complications than hemodialysis, we aimed to show that PD is a good and a non-inferior option for dialysis therapy with comparable outcome in both patient and technique survival. This was a retrospective analysis of all patients who were on PD from February 2011 to December 2014. Peritonitis rate, exit site infection rate, and all-cause mortality rate were all assessed for this period. Peritonitis rate during the 1 st year, 2011, was 0.92 incidents/year. This number had progressively declined in the following years; in 2012, it was 0.65 incidents/year; in 2013, it was 0.58 incidents/year; and in 2014, it was 0.38 incidents/year. This improvement in the rate of peritonitis incidence could be explained by better education of patients and meticulous supervision of the nursing staff. Farwaniya Hospital Kidney Center had an all-cause mortality rate of 9.3% among patients on renal replacement therapy in 2011. In 2012, all-cause mortality rate increased to 17.1%. The following year, 2013, it decreased to 14.3%, and in 2014, all-cause mortality rate dropped further to 7.6%. All-cause mortality rate among PD patients was zero in 2011. In 2012, the all-cause mortality rate in PD was 11.54%, and in 2013, it decreased to 10.52%. Then, again in 2014, the all-cause mortality rate among PD patients was zero. This improvement in all-cause mortality rate could be explained by the better medical care offered to the end-stage renal disease patients, in particular PD patients, in Farwaniya Hospital Kidney Center.

    We report a case of peritoneal mesothelioma discovered in a patient during peritoneal dialysis. The patient was a 55-year-old woman who had no history of asbestos exposure. Owing to end-stage kidney failure, she had been undergoing peritoneal dialysis for over 8 years, and she had been diagnosed with encapsulating peritoneal sclerosis. She was admitted to the hospital for intestinal obstruction. Three months later, she noticed an enlarging mass in the epigastric region. Computed tomography showed a 10-cm mass originating in the abdominal wall that had invaded the liver. It was diagnosed as malignant mesothelioma via biopsy. Cases of sarcoma-like mass-forming peritoneal mesothelioma are rare, and there are no prior reports of encapsulating peritoneal sclerosis complicated by malignant peritoneal mesothelioma. Thus, this unique case of peritoneal mesothelioma can provide us with important knowledge about this rare entity. PMID:27628605

    We describe a case of peritonitis with isolation of a group JK corynebacterium from the peritoneal effluent in a patient undergoing continuous ambulatory peritoneal dialysis and treated with corticosteroids. Therapy with intraperitoneal vancomycin resulted in a rapid eradication of the organism. However, only 1 month after discontinuation of the 26-day therapy, a second episode of peritonitis with JK corynebacterium occurred. After vancomycin was restarted, the organism disappeared again from the peritoneal fluid, but the patient died a few days later from heart failure apparently unrelated to the infection. Some authors have mentioned the isolation of diphtheroids (without further identification) from peritoneal effluent of continuous ambulatory peritoneal dialysis patients, but to our knowledge, this is the first report of peritonitis associated with JK corynebacterium, an opportunistic organism that must be differentiated from other corynebacteria.

    Objective: to analyze the complications related to peritonitis and catheter exit-site infections, in patients on peritoneal dialysis at home. Method: quantitative and cross-sectional study, carried out with 90 patients on peritoneal dialysis at home, in a municipality in the Northeast region of Brazil. For data collection, it was used two structured scripts and consultation on medical records. Descriptive analysis and comparison tests among independent groups were used, considering p<0.05 as level of statistical significance. Results: by comparing the frequency of peritonitis and the length of treatment, it was found that patients over two years of peritoneal dialysis were more likely to develop peritonitis (X²=6.39; p=0.01). The number of episodes of peritoneal catheter exit-site infection showed association with the length of treatment (U=224,000; p=0.015). Conclusion: peritonitis and catheter exit-site infection are associated with the length of treatment. PMID:26487141

    Pediatric Spontaneous Bile duct perforation is a rare clinical condition with only around 150 cases reported worldwide. Early management gives excellent prognosis but the condition often presents a diagnostic dilemma. Hepato-biliary Technetium-99m-iminodiacetic acid scintiscan is the diagnostic investigation of choice but its availability in third world countries is limited. We present two cases of spontaneous biliary peritonitis in children, which were diagnosed without scintiscanning. The first case was a one-and -a half-year-old child, who was diagnosed with biliary peritonitis without pneumoperitoneum by a combination of Ultrasound (USG), Contrast enhanced computed tomography (CECT), and Magnetic Resonance Imaging (MRI). The child underwent USG-guided drainage and subsequent cholecystectomy with hepatico-jejunostomy. The second child also had biliary peritonitis without pneumoperitoneum, which was initially suspected on USG. CECT revealed dilated gall bladder and fluid collection in sub-hepatic space and pelvis.

    Pediatric Spontaneous Bile duct perforation is a rare clinical condition with only around 150 cases reported worldwide. Early management gives excellent prognosis but the condition often presents a diagnostic dilemma. Hepato-biliary Technetium-99m-iminodiacetic acid scintiscan is the diagnostic investigation of choice but its availability in third world countries is limited. We present two cases of spontaneous biliary peritonitis in children, which were diagnosed without scintiscanning. The first case was a one-and -a half-year-old child, who was diagnosed with biliary peritonitis without pneumoperitoneum by a combination of Ultrasound (USG), Contrast enhanced computed tomography (CECT), and Magnetic Resonance Imaging (MRI). The child underwent USG-guided drainage and subsequent cholecystectomy with hepatico-jejunostomy. The second child also had biliary peritonitis without pneumoperitoneum, which was initially suspected on USG. CECT revealed dilated gall bladder and fluid collection in sub-hepatic space and pelvis. Abdominal paracentesis revealed presence of bile. The child responded to conservative therapy. Both are doing well on two-year follow-up. In a patient with jaundice, biliary tract abnormalities and/or free fluid, either generalized or localized to peri-cholecystic/sub-hepatic space on USG/CT/MRI, in the absence of pneumoperitoneum, suggest a diagnosis of biliary perforation even in the absence of scintiscanning.

    The optimal method to assess the adequacy of peritoneal dialysis therapies is controversial. Today, the adequacy must not be considered as a number or a concept assessed only by two parameters (total KT/V urea and total solute clearance) but defined by many more items. In the absence of data, based on theoretical considerations, the reanalysis of the CANUSA study showed that renal kidney function, rather than peritoneal clearance, was associated with improved survival. Residual renal function is considered as a major predictor factor of cardiovascular mortality. Results of this reanalysis were supported by the adequacy data in ADEMEX, EAPOS and ANZDATA studies. Therefore, clinical assessment plays a major role in PD adequacy. The management of fluid balance, the regular monitoring of malnutrition, the control of mineral metabolism and particularly the glucose load, considered as the "corner-stone" of the system, are the main points to be considered in the adequacy of PD patients. The essential goal is to minimize glucose load by glucose-sparing strategies in order to reduce the neoangiogenesis of the peritoneal membrane. PMID:23850000

    Benign multicystic peritoneal mesotheliomas are rare: pre-operative diagnosis relies on proper imaging. The differential diagnosis includes pseudomyxoma peritonei and other peritoneal cysts. Absence of previous surgical resection offers the best chance of success when complete resection is performed in a specialized center. We report the case of a 43 year-old man with benign multicystic peritoneal mesothelioma treated by cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. PMID:24433857

    Hypertonic dehydration in a 13-year-old boy with ketoacidotic diabetic coma has been treated successfully with peritoneal dialysis and isotonic fluids. Modes of treatment with either hypotonic or isotonic fluids are discussed, as is the feasibility of peritoneal dialysis. We recommend isotonic solutions composed of equal parts of 5.5% glucose and 0.9% sodium chloride combined with peritoneal dialysis in order to secure a relatively slow correction of the hypertonic state.

    In carcinoma, such as of the lung, the histological subtype is important to select an appropriate therapeutic strategy for patients. However, carcinomas with poor differentiation cannot always be distinguished on the basis of morphology alone nor on clinical findings. Hence, delineation of poorly differentiated adenocarcinoma and squamous cell carcinoma, the 2 most common epithelial-origin carcinomas, is pivotal for selection of optimum therapy. Herein, we explored the potential utility of trefoil factor 3 (TFF3) as a biomarker for primary lung adenocarcinoma and extrapulmonary adenocarcinomas derived from different organs. We observed that 90.9% of lung adenocarcinomas were TFF3-positive, whereas no expression of TFF3 was observed in squamous cell carcinomas. The subtype of lung carcinoma was confirmed by four established biomarkers, cytokeratin 7 and thyroid transcription factor 1 for adenocarcinoma and P63 and cytokeratin 5/6 for squamous cell carcinoma. Furthermore, expression of TFF3 mRNA was observed by quantitative PCR in all of 11 human lung adenocarcinoma cell lines and highly correlated with markers of the adenocarcinomatous lineage. In contrast, little or no expression of TFF3 was observed in 4 lung squamous cell carcinoma cell lines. By use of forced expression, or siRNA-mediated depletion of TFF3, we determined that TFF3 appeared to maintain rather than promote glandular differentiation of lung carcinoma cells. In addition, TFF3 expression was also determined in adenocarcinomas from colorectum, stomach, cervix, esophagus, and larynx. Among all these extrapulmonary carcinomas, 93.7% of adenocarcinomas exhibited TFF3 positivity, whereas only 2.9% of squamous cell carcinomas were TFF3-positive. Totally, 92.9% of both pulmonary and extrapulmonary adenocarcinomas exhibited TFF3 positivity, whereas only 1.5% of squamous cell carcinomas were TFF3-positive.

    For intraoperative consultation of mucinous adenocarcinoma involving the ovary, it would be useful to have approaching methods in addition to the traditional limited microscopic findings in order to determine the nature of the tumors. Mucinous adenocarcinomas involving the ovaries were evaluated in 91 cases of metastatic mucinous adenocarcinomas and 19 cases of primary mucinous adenocarcinomas using both an original algorithm (unilateral ≥10 cm tumors were considered primary and unilateral <10 cm tumors or bilateral tumors were considered metastatic) and a modified cut-off size algorithm. With 10 cm, 13 cm, and 15 cm size cut-offs, the algorithm correctly classified primary and metastatic tumors in 82.7%, 87.3%, and 89.1% of cases and in 80.6%, 84.9%, and 87.1% of signet ring cell carcinoma (SRC) excluded cases. In total cases and SRC excluded cases, 98.0% and 97.2% of bilateral tumors were metastatic and 100% and 100% of unilateral tumors <10 cm were metastatic, respectively. In total cases and SRC excluded cases, 68.4% and 68.4% of unilateral tumors ≥15 cm were primary, respectively. The diagnostic algorithm using size and laterality, in addition to clinical history, preoperative image findings, and operative findings, is a useful adjunct tool for differentiation of metastatic mucinous adenocarcinomas from primary mucinous adenocarcinomas of the ovary.

    Mesonephric carcinomas are rare in the female genital tract and usually are found in sites where embryonic remnants of wolffian ducts are usually detected, such as the uterine cervix, broad ligament, mesosalpinx and exceptionally rarely in the uterine corpus. To date, only four cases of mesonephric carcinomas arising in the uterine corpus have been described in literature. Here we report two cases of mesonephric carcinomas arising in a deep intramural location of the uterine corpus in a 55-year-old woman and a 62-year-old woman in Chinese populations. It is believed to be the first report in China. Both cases presented with a little postmenopausal bleeding. Before hospitalized, uterine curettages were programmed for both cases. The pathology reports were mesonephric adenocarcinoma. A total hysterectomy and bilateral salpingo-oophorectomy were performed. On gross examination, the tumors of both cases were confined to the myometrium. Microscopic examination found both tumors of these two cases were adenocarcinomas mixed with spindle cell component. The most primary histologic patterns of the mesonephric adenocarcinomas were tubular glands that varied in size and were lined by one to several layers of columnar cells. Immunohistochemically, the tumor cells expressed positive with CD10, calretinin, vimentin, cytokeratin (AE1/AE3) and epithelial membrane antigen (EMA); but expressions of ER and PR were completely negative. The peculiar location of mesonephric carcinoma of the uterine corpus may be misinterpreted as other histological type neoplasms. Awareness of this rare phenomenon and immunostaining for markers of mesonephric carcinoma can prevent from making a false diagnosis. PMID:25400789

    Background The pathogenesis of oral tori has long been debated and is thought to be the product of both genetic and environmental factors, including occlusal forces. Another proposed mechanism for oral tori is the combination of biomechanical forces, particularly in the oral cavity, combined with cortical bone loss and trabecular expansion, as one might see in the early stages of primary hyperparathyroidism. This study investigated the epidemiology of torus palatinus (TP) and torus mandibularis (TM) in peritoneal dialysis patients, and analyzed the influences of hyperparathyroidism on the formation of oral tori. Method In total, 134 peritoneal dialysis patients were recruited between July 1 and December 31, 2015 for dental examinations for this study. Patients were categorized into two subgroups based on the presence or absence of oral tori. Demographic, hematological, biochemical, and dialysis-related data were obtained for analysis. Results The prevalence of oral tori in our sample group was high at 42.5% (57 of 134), and most patients with oral tori were female (61.4%). The most common location of tori was TP (80.7%), followed by TP and TM (14.0%), then TM (5.3%). All 54 TP cases were at the midline, and most were <2 cm (59.3%), flat (53.7%), and located in the premolar region (40.7%). Of the 11 TM cases, all were bilateral and symmetric, mostly <2 cm (81.9%), lobular (45.4%), and located at premolar region (63.6%). Interestingly, patients with oral tori had slightly lower serum levels of intact parathyroid hormones than those without oral tori, but the difference was not statistically significant (317.3±292.0 versus 430.1±492.6 pg/mL, P = 0.126). In addition, patients with oral tori did not differ from patients without tori in inflammatory variables such as serum high sensitivity C-reactive protein levels (6.6±8.2 versus 10.3±20.2 mg/L, P = 0.147) or nutritional variables such as serum albumin levels (3.79±0.38 versus 3.77±0.45 g/dL, P = 0

    The prognosis of gastric cancer (GC) patients with peritoneal dissemination remains poor, and a better understanding of the underlying mechanisms is critical for the development of new treatments that will improve survival in these patients. This study aimed to clarify the clinical and biological role of two key metastasis-associated long non-coding RNAs (lncRNAs) in GC. We analyzed the expression levels of two lncRNAs-Metastasis-Associated Lung Adenocarcinoma Transcript 1 (MALAT1) and HOX-Antisense Intergenic RNA (HOTAIR)-by real-time reverse transcription PCR in 300 gastric tissues (150 GC and 150 adjacent normal mucosa), and in seven GC cell lines. Functional characterization for the role of HOTAIR in GC was performed by small interfering RNA (siRNA) knockdown, followed by series of in-vitro and in-vivo experiments. Expression of both lncRNAs was significantly higher in cancerous tissues than in corresponding normal mucosa, and higher expression of these lncRNAs significantly correlated with peritoneal metastasis in GC patients. In addition, elevated HOTAIR expression emerged both as an independent prognostic and risk factor for peritoneal dissemination. SiRNA knockdown of HOTAIR in GC cells significantly inhibited cell proliferation, migration and invasion, but concurrently enhanced the anoikis rate in transfected cells. In an in vivo assay, HOTAIR siRNA-transfected MKN45 cells injected into nude mice inhibited the growth of xenograft tumors and peritoneal metastasis compared with controls. Our data provide novel evidence for the biological and clinical significance of HOTAIR expression as a potential biomarker for identifying patients with peritoneal metastasis, and as a novel therapeutic target in patients with gastric neoplasia.

Since the predictive value of C-reactive protein (CRP) in PD fluid has not been assessed, the objective of the present study is to evaluate its predictive value and clinical correlation in patients on PD with peritonitis. One hundred and twenty patients on continuous ambulatory PD (CAPD) were enrolled and their serum and fluid CRP (Fl. CRP) were evaluated at the start of CAPD. All patients who developed peritonitis were further evaluated for serum and fluid CRP. The patients were categorized into four groups, namely: normal patients (control group), patients with peritonitis, patients with peritonitis leading to catheter removal, and death due to peritonitis. Sixty-five patients developed peritonitis of whom, catheter removal was performed in eight patients. Five patients died due to peritonitis-related complications. Fl. CRP showed a significant difference among the three groups, unlike S. CRP. Estimation of CRP in the peritoneal fluid may be a useful marker to monitor the onset of peritonitis. PMID:27215236

    A 70-years of age, male patient with underlying type 2 diabetes mellitus, hypertension, dyslipidemia and ischemic heart disease had undergone continuous ambulatory peritoneal dialysis (CAPD)for 3 years without any episodes of peritonitis. He was diagnosed with necrotizing fasciitis and later developed peritonitis after receiving a laceration from an aquatic injury suffered during the flood disaster of 2011. The blood culture, necrotic tissue and the clear dialysate collected upon admission had shown Aeromonas sobria. The route of peritonitis may be from the hematogenous spread of A. sobria resulting in necrotizing fasciitis. A. sobria should be considered as the pathogen of peritonitis in PD patients who have history of wounds from contaminated water. We suggest that the PD patients who present with septicemia and did not meet the criteria for peritonitis, the initial dialysate effluent should be sent for culture. The benefit of this is to allow early recognition and treatment of peritonitis.

    An 11-year-old Quarter Horse mare was presented with ventral edema and pleural effusion, secondary to a disseminated ovarian adenocarcinoma. Bilateral thoracocentesis yielded 30 L of thin, blood-tinged fluid, which was a modified transudate. Cytologic examination of the fluid revealed large atypical cells, suggestive of carcinomatous neoplasia. Similar cells were found in the peritoneal fluid. The mare was euthanatized. Necropsy revealed a 35-cm diameter mass in the cranial mediastinum, ventral to the trachea. The left ovary was 25 cm in diameter and most of the parenchyma was replaced by red or brown friable tissue, containing numerous 1-to 3-mm cysts. Papillary adenocarcinoma of the ovary was diagnosed, based on the appearance and arrangement of tumor cells in the ovary, sublumbar and tracheobronchial lymph nodes, and mediastinal mass. Ovarian neoplasia should be considered in the differential diagnosis of pleural effusion in the horse. PMID:4030465

The mare had been used for pleasure riding since surgery, but had recently developed progressive dyspnea. The mare had clinical evidence of pleural effusion, but died before further clinical examination and treatment were instituted. Necropsy revealed deep mammary masses with similar nodules in the deep inguinal, renal, and mediastinal lymph nodes and in the lungs, pericardium, visceral and parietal pleurae, and left ovary. The masses were identified as papillary mammary gland adenocarcinoma. Large volumes of free pleural and peritoneal fluid were detected. The pleural fluid contained similar neoplastic cells that could have been readily detected by exfoliative cytologic examination had the mare survived. PMID:2254151

    Peritoneal dialysis is a form of renal replacement alternative to the hemodialysis. During this treatment, the peritoneal membrane acts as a permeable barrier for exchange of solutes and water. Continual exposure to dialysis solutions, as well as episodes of peritonitis and hemoperitoneum, can cause acute/chronic inflammation and injury to the peritoneal membrane, which undergoes progressive fibrosis, angiogenesis, and vasculopathy, eventually leading to discontinuation of the peritoneal dialysis. Among the different events controlling this pathological process, epithelial to mesenchymal transition of mesothelial cells plays a main role in the induction of fibrosis and in subsequent functional deterioration of the peritoneal membrane. Here, the main extracellular inducers and cellular players are described. Moreover, signaling pathways acting during this process are elucidated, with emphasis on signals delivered by TGF-β family members and by Toll-like/IL-1β receptors. The understanding of molecular mechanisms underlying fibrosis of the peritoneal membrane has both a basic and a translational relevance, since it may be useful for setup of therapies aimed at counteracting the deterioration as well as restoring the homeostasis of the peritoneal membrane.

    The author reviews briefly the history of peritoneal dialysis, and highlights the significance of the work of two Hungarian nephrologists, Stephen I. Vas and István Taraba . By now, peritoneal dialysis has been considered as equal renal replacement modality compared to haemodialysis. It is even more advantageous in the protection of the patients' residual renal function, morbidity-mortality indices, and quality of life peritoneal dialysis in the first two years. From economical point of view peritoneal dialysis is less expensive than hemodialysis, therefore in the future its greater role can be expected in the treatment of more and more renal patients. The recently achieved technical development, and also the more widespread use of the automated peritoneal dialysis machines contribute to quality improvement. The peritoneal dialysis therapy, by the patients' self-treatment, establishes a new kind of relationship between the patients and the medical personnel; there is a growing requirement for patient education, the patients' self-esteem and cooperation increase, which altogether provides better results in rehabilitation and higher quality of life. Our national peritoneal dialysis utilization falls behind the European achievements, but has been growing dynamically, and we can expect an increase of the number of renal patients on peritoneal dialysis.

Herein, we report a case of gastric adenocarcinoma in a 56-year-old man with prostatic metastasis diagnosed through the analysis of biopsy specimens from representative lesions in the stomach and prostate gland. Immunohistochemistry of the prostatic tissue showed positive staining for cytokeratin 7 and negative staining for prostate-specific antigen (PSA), whereas the serum PSA level was normal, confirming the diagnosis of prostatic metastasis from carcinoma of the stomach.

    Sarcoidosis is a multisystem inflammatory disorder of unknown etiology. It shows a great variety of clinical presentation, organ involvement, and disease progression. Lungs and lymphoid system are the most common sites involved with a frequency of 90% and 30%, respectively. Extrapulmonary involvement of sarcoidosis is reported in 30% of patients and abdomen is the most frequent site. Furthermore, peritoneal involvement is extremely rare in sarcoidosis. The case presented here described peritoneal manifestations of sarcoidosis without involvement of lungs. A 78-year-old woman possessing signs of malignancy on blood test and abdominal magnetic resonance imaging underwent laparatomy with a suspicion of ovarian malignancy. The macroscopic interpretation during surgery was peritoneal carcinomatosis. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, peritoneal biopsies, total omentectomy, and appendectomy were performed. Final histopathological result revealed the diagnosis of sarcoidosis. Clinicians must keep in mind that peritoneal sarcoidosis can mimic intra-abdominal malignancies. PMID:26558122

    Meconium peritonitis is a rare prenatal disease with an increased rate of morbidity and mortality in the neonatal period. Distinctive features revealed by prenatal and postnatal ultrasoundmay be present: abdominal calcifications, ascites, polyhydramnios, meconium pseudocyst, echogenic mass and dilated bowel or intestinal obstruction. Establishing clear postnatal treatment and prognosis is difficult because of the heterogeneity of the results obtained by ultrasound. The aim of the study is to determine how prenatal diagnosis of meconium peritonitis is associated with perinatal management and further evolution. Clinical results are different depending on the presence of antenatal diagnosis of meconium peritonitis and its form, which can be mild or severe. Surgical treatment and management of meconium peritonitis depend on the clinical presentation of the newborn. Meconium peritonitis diagnosed prenatally differs from that of the newborn, not only concerning the mortality rates but also through reduced morbidity and overall better prognosis.

    Warthin tumor is a well-defined benign salivary gland neoplasm consisting of both epithelial and lymphoid components. The tumor is the second most common benign tumor next to pleomorphic adenoma. We present a case of adenocarcinoma, not otherwise classified, arising in unilateral Warthin tumor of the parotid gland in a 63-year-old male patient. Carcinomas arising in or from the epithelial component of a preexisting parotid Warthin tumor are rare and differential diagnosis of metastasis from an adenocarcinoma in Warthin tumor is important. The patient underwent a complete and thorough work-up, and no other primary malignant lesion was found. No other primary malignant lesion had manifested at the last one year follow-up period.

    Peritoneal dialysis therapy has increased in popularity since the end of the 1970s. This method provides a patient survival rate equivalent to hemodialysis and better preservation of residual renal function. However, technique failure by peritonitis, and ultrafiltration failure, which is a multifactorial complication that can affect up to 40% of patients after 3 years of therapy. Encapsulant peritoneal sclerosis is an extreme and potentially fatal manifestation. Causes of inflammation in peritoneal dialysis range from traditional factors to those related to chronic kidney disease per se, as well as from the peritoneal dialysis treatment, including the peritoneal dialysis catheter, dialysis solution, and infectious peritonitis. Peritoneal inflammation generated causes significant structural alterations including: thickening and cubic transformation of mesothelial cells, fibrin deposition, fibrous capsule formation, perivascular bleeding, and interstitial fibrosis. Structural alterations of the peritoneal membrane described above result in clinical and functional changes. One of these clinical manifestations is ultrafiltration failure and can occur in up to 30% of patients on PD after five years of treatment. An understanding of the mechanisms involved in peritoneal inflammation is fundamental to improve patient survival and provide a better quality of life. PMID:22547910

    Total leukocyte count, microscopy, and conventional bacteriologic culture (10-ml sediment) of dialysis effluent were assessed for their ability to detect peritonitis in patients on peritoneal dialysis. A total of 73 patients were surveyed over a 17-month period. Laboratory findings included an examination of 1,774 dialysate samples and culture results from blood, wounds, indwelling catheters, and other specimens. Of 90 peritonitis events, 72 were culture positive. Gram-stained films were positive in no more than 14% of the dialysates collected during periods of clinical peritonitis. Factors which adversely affected the microscopic or cultural detection of microorganisms in effluent included the concentration of organisms in dialysate, antibiotic therapy, and growth medium used. Seeding of the peritoneum with organisms originating from other sites of infection or colonization was documented, although infrequent, yet bacteremia secondary to peritonitis was not seen. Because of the frequent isolation of microorganisms from dialysates in the absence of clinical peritonitis, culture-positive findings were a poor predictor of peritonitis without other evidence of infection. Detection of peritonitis by total leukocyte count (without a differential count) of dialysate specimens was adversely affected by the overlap in cell counts between dialysates collected either during or in the absence of peritonitis. This was attributed in part to nonspecific increases in dialysate cell count in the absence of peritonitis and was associated with intermittent dialysis and extraperitoneal infection. PMID:3429626

    The lung is a frequent site of metastatic involvement, and in many cases the differential diagnosis between a metastasis and a primary carcinoma is a substantial question. TTF-1 is considered as a reliable marker for differential diagnosis in distinguishing primary lung carcinoma and metastasis, especially when dealing with an adenocarcinoma or a large-cell carcinoma. It was generally thought that adenocarcinomas arising in the gastrointestinal tract do not express TTF-1. Recently, it has been reported that a small percentage (1.8%-5.8%) of intestinal adenocarcinoma TTF-1 positive show differences in sensitivity/specificity depending on the antibody clones. We report a case of lung localization of a TTF-1 positive adenocarcinoma in a patient with a history of colon adenocarcinoma. Based on the current results and previous reports, we propose the following criteria for diagnosing lung metastasis from TTF-1 positive intestinal adenocarcinoma. 1) Clinical features and anamnestic history are diagnostic milestones, and provide very important information as a prognostic parameter of primary carcinoma and the time interval between the two localizations (primary and metastasis). 2) The histologic features are compatible with an enteric differentiation. 3) TTF-1 must be tested in the primary carcinoma. 4) In lung lesions, in association with TTF-1, it could be useful to test other immunohistochemical markers such as CDX-2 and NapsinA. 5) Testing other immunohistochemical or molecular markers in either lesion is not very useful. Heterogeneity between primary and metastatic lesions has been reported in the literature. Application of the above-mentioned criteria would simplify diagnosis of lung metastases from TTF-1 positive intestinal adenocarcinoma. PMID:23946985

    Background. The need for preoperative chemoradiation or short-course radiation in all T3 rectal tumors is a controversial issue. A multicenter phase II trial was undertaken to evaluate the efficacy and safety of neoadjuvant capecitabine and oxaliplatin combined with bevacizumab in patients with intermediate-risk rectal adenocarcinoma. Methods. We recruited 46 patients with T3 rectal adenocarcinoma selected by magnetic resonance imaging (MRI) who were candidates for (R0) resection located in the middle third with clear mesorectal fascia and who were selected by pelvic MRI. Patients received four cycles of neoadjuvant capecitabine and oxaliplatin combined with bevacizumab (final cycle without bevacizumab) before total mesorectal excision (TME). In case of progression, preoperative chemoradiation was planned. The primary endpoint was overall response rate (ORR). Results. On an intent-to-treat analysis, the ORR was 78% (n = 36; 95% confidence interval [CI]: 63%–89%) and no progression was detected. Pathologic complete response was observed in nine patients (20%; 95% CI: 9–33), and T downstaging was observed in 48%. Forty-four patients proceeded to TME, and all had R0 resection. During preoperative therapy, two deaths occurred as a result of pulmonary embolism and diarrhea, respectively, and one patient died after surgery as a result of peritonitis secondary to an anastomotic leak (AL). A 13% rate of AL was higher than expected. The 24-month disease-free survival rate was 75% (95% CI: 60%–85%), and the 2-year local relapse rate was 2% (95% CI: 0%–11%). Conclusion. In this selected population, initial chemotherapy results in promising activity, but the observed toxicity does not support further investigation of this specific regimen. Nevertheless, these early results warrant further testing of this strategy in an enriched population and in randomized trials. PMID:25209376

    Interleukin-8 (IL-8) is a chemoattractant that is highly selective for neutrophils. This study was designed to investigate the presence of IL-8 in peritoneal fluid of patients with acute appendicitis. The clinical circumstances underlying the secretion of IL-8 by mesothelium and its mechanism of activation have not been defined. In an in vitro model for bacterial peritonitis the role of bacteria in activating human mesothelial cells to secrete IL-8 was studied. Cultured human mesothelium was incubated with various species of pathogenic bacteria, isolated from peritoneal exudate fluids of patients with appendicitis. The amount of IL-8 secreted by the cultured mesothelial cells was determined in an IL-8 ELISA, as IL-8 was present in the original peritoneal fluid of these patients. Peritoneal fluids from patients with a perforated appendix were found to contain a significantly higher concentration of IL-8 compared to peritoneal fluids from patients with nonperforating appendicitis (121.6 (57.8) ng/ml versus 0.2 (0.07) ng/ml, respectively; mean (SEM), P < or = 0.01). Species of Bacteroïdes and Fusobacterium necrophorum induced IL-8 secretion from cultured mesothelial monolayers to levels comparable to those found in peritoneal fluids in vivo. Heat-killed bacteria and bacterial supernatant were also able to stimulate mesothelium to secrete IL-8. The results suggest that in the early phase of bacterial peritonitis the influx of PMN is regulated by bacteria-induced IL-8 secretion by the mesothelium lining the peritoneal cavity.

    Breast metastasis from other primary carcinoma is very rare and could be difficult to identify despite immunohistochemistry analysis. Breast metastasis from lung adenocarcinoma can mimic triple-negative breast cancer. Given the prognosis and therapeutic challenges, a correct diagnosis appears essential, and molecular biomarkers could be useful. We report the case of a 52-year-old woman with a breast mass initially diagnosed as primary breast cancer and secondarily attached to breast metastasis from an EGFR-mutated lung adenocarcinoma. The same activating EGFR mutations were identified in both the primary lung carcinoma and the breast metastasis.

    A 79-year-old man on continuous ambulatory peritoneal dialysis (CAPD) developed abdominal pain and cloudy peritoneal fluid two days after colonoscopy that revealed multiple diverticula. The white blood cell count was 9,000 cells/μL, C-reactive protein level was 6.86 mg/dL, and the white blood cell count of the peritoneal fluid was 7,800 cells/μL, suggesting acute peritonitis. Empiric therapy consisting of cefazolin and ceftazidime slowly improved the patient's symptoms. The initial microbiological examination of the peritoneal fluid demonstrated Morganella morganii. He was changed from CAPD to hemodialysis. It is important to consider M. morganii peritonitis in patients with colonic diverticula.

    Protein energy wasting is a major complication in peritoneal dialysis. It is leading to a poor quality of life and increasing mortality. Diagnosis must be early, according to criteria defined by the International society of renal nutrition and metabolism. It is necessary to appropriate the diagnostic tools with dialysis method. The nutritional care is difficult in peritoneal dialysis. Indeed, studies are limited and practical nutrition is complex. In this point of view, we propose to treat guidelines for protein energy wasting, in peritoneal dialysis patients. PMID:27320370

    Preservation of peritoneal cavity homeostasis and peritoneal membrane function is critical for long-term peritoneal dialysis (PD) treatment. Several microRNAs (miRNAs) have been implicated in the regulation of key molecular pathways driving peritoneal membrane alterations leading to PD failure. miRNAs regulate the expression of the majority of protein coding genes in the human genome, thereby affecting most biochemical pathways implicated in cellular homeostasis. In this review, we report published findings on miRNAs and PD therapy, with emphasis on evidence for changes in peritoneal miRNA expression during long-term PD treatment. Recent work indicates that PD effluent- (PDE-) derived cells change their miRNA expression throughout the course of PD therapy, contributing to the loss of peritoneal cavity homeostasis and peritoneal membrane function. Changes in miRNA expression profiles will alter regulation of key molecular pathways, with the potential to cause profound effects on peritoneal cavity homeostasis during PD treatment. However, research to date has mainly adopted a literature-based miRNA-candidate methodology drawing conclusions from modest numbers of patient-derived samples. Therefore, the study of miRNA expression during PD therapy remains a promising field of research to understand the mechanisms involved in basic peritoneal cell homeostasis and PD failure.

Un niño de 10 años de edad con insuficiencia renal terminal causada por síndrome urémico hemolítico atípico ingresó a nuestro hospital con dolor abdominal y fiebre. El líquido de la diálisis peritoneal era turbio; en el examen microscópico se observaron leucocitos abundantes. Se inició tratamiento con cefepime intraperitoneal. En el cultivo del líquido peritoneal se aisló Campylobacter jejuni, por lo que se agregó claritromicina oral al tratamiento. Al finalizar el tratamiento, el resultado del cultivo del líquido peritoneal era negativo. Hasta donde sabemos, no se había informado previamente peritonitis por C. jejuni en niños. Conclusión. Si bien la peritonitis por C. jejuni es rara en los niños, debe considerarse como factor etiológico de la peritonitis.

    Despite technological improvements in dialysis connectology and dialysis technique, peritonitis remains the most common and most significant complication of peritoneal dialysis (PD) in children. Most children undergoing chronic PD experience none or only one peritonitis episode, while others have multiple episodes or episodes secondary to unusual organisms. Knowledge of potential risk factors and likely patient outcome is imperative if treatment is to be optimized. In this review we will, in turn, describe episodes of peritonitis that are characterized as either relapsing, recurrent, repeat or zoonosis-related to highlight the clinical issues that are commonly encountered by clinicians treating these infections.

    In patients on continuous ambulant peritoneal dialysis (CAPD) treatment, the peritoneal membrane is continuously exposed to the high glucose concentration contained in the dialysate. This may lead to the local generation of advanced glycation end-products (AGEs). To test this hypothesis we evaluated the plasma and dialysate AGE concentrations in five CAPD patients. The dialysate was measured after a 1 h and after a 12 h dwell time. Additionally, in two patients an immunohistochemical investigation of the peritoneal membrane for AGE was performed. For the determination of AGE an ELISA using a polyclonal antibody against AGE bovine serum albumin was used; the immunohistochemical staining was performed using the streptavidin-biotin complex method. We found only low concentrations of AGE in the dialysate after a 1 h dwell time; after 12 h, however, the dialysate AGE was even greater than the plasma concentration. In both peritoneal specimens we found positive staining for AGE in the interstitium of the mesothelial layer. The dialysate AGE contained a high proportion of high-molecular-weight AGE proteins and low-molecular-weight AGE was found to be in the same concentration range as the total serum AGE. We conclude that there is local generation of AGE in the peritoneal membrane and a 'washing out' of AGE from the peritoneal membrane during longer dwell times. We speculate that the accumulation of AGE might lead to some of the functional and morphological alterations observed after long-term CAPD.

    Peritoneal metastasis is a primary cause of mortality in patients with gastric cancer. Urokinase-type plasminogen activator (uPA) has been demonstrated to be associated with tumor cell metastasis through the degradation of the extracellular matrix. The present study aimed to investigate the mechanisms of the uPA system in gastric cancer with peritoneal metastasis. Expression of uPA, uPA receptor (uPAR) and plasminogen activator inhibitor-1 (PAI-1) in four gastric cell lines (AGS, SGC7901, MKN45 and MKN28) was measured by semiquantitative reverse transcription polymerase chain reaction, enzyme-linked immunosorbent assay and western blotting. uPA activity was detected using a uPA activity kit. Peritoneal implantation models of rats were established by injecting four gastric cancer cell lines for the selection of the cancer cells with a high planting potential. Biological behaviors, including adhesion, migration and invasion, were determined using a methyl thiazolyl tetrazolium assay. Expression of the uPA system was observed to be highest in the SGC7901 cells among the four gastric cell lines. uPA activity was observed to be highest in the MKN45 cells and lowest in the AGS cells. Furthermore, peritoneal implantation analysis demonstrated that no peritoneal tumors were identified in the AGS cells, whilst the tumor masses observed in the SGC7901 and MKN45 cells were of different sizes. The survival times of the rats injected with the MKN28 and SGC7901 cells were longer than those of the rats injected with the MKN45 cells. Antibodies for uPA, uPAR and PAI-1 in the uPA system had the ability to inhibit the adhesion, migration and invasion of peritoneal metastasis in the gastric cancer cells. The results of the present study demonstrated that the uPA system was positively associated with peritoneal metastasis in gastric cancer. PMID:27313768

    The combined treatment concept of cytoreductive surgery (CRS) and Hyperthermic intraperitoneal chemotherapy (HIPEC) has shown to be an efficient therapeutic option for selected patients with primary and secondary peritoneal carcinomatosis (PC). This strategy represents the standard of care for diseases like pseudomyxoma peritonei and peritoneal mesothelioma, and offers the best long-term results for PC from colorectal cancer. Despite these results, skepticism exists regarding this therapeutic approach partly because of its perceived high toxicity. In this article, we review the current evidence on complications that can occur after CRS and HIPEC and the risk factors associated with increased incidence of morbidity and mortality. PMID:27065713

    Low-grade nasopharyngeal papillary adenocarcinoma is an extremely rare tumor, with only a limited number of cases reported in the literature. Some published studies have paid more attention to the clinicopathological features of nasopharyngeal adenocarcinoma, while little effort has been made to study the optimal therapeutic strategies. We report about a woman diagnosed with low-grade nasopharyngeal papillary adenocarcinoma. She received the treatment approach that combined transnasal endoscopic surgery to remove the lesion with postoperative radiotherapy for nasal cavity. There was no evidence of recurrence after 4 months of surgery, and further follow-up is being continued. Through this example, we wanted to explore the optimal therapeutic strategies for primary nasopharyngeal adenocarcinomas. PMID:27274289

    We have generated a molecular taxonomy of lung carcinoma, the leading cause of cancer death in the United States and worldwide. Using oligonucleotide microarrays, we analyzed mRNA expression levels corresponding to 12,600 transcript sequences in 186 lung tumor samples, including 139 adenocarcinomas resected from the lung. Hierarchical and probabilistic clustering of expression data defined distinct subclasses of lung adenocarcinoma. Among these were tumors with high relative expression of neuroendocrine genes and of type II pneumocyte genes, respectively. Retrospective analysis revealed a less favorable outcome for the adenocarcinomas with neuroendocrine gene expression. The diagnostic potential of expression profiling is emphasized by its ability to discriminate primary lung adenocarcinomas from metastases of extra-pulmonary origin. These results suggest that integration of expression profile data with clinical parameters could aid in diagnosis of lung cancer patients. PMID:11707567

    Hepatoid adenocarcinoma of the urachus is a rare condition. We present the case of a 51-year-old female who developed abdominal pain and hematuria. Pelvic magnetic resonance imaging (MRI) reported an urachal mass with invasion to the bladder that was resected by partial cystectomy. On light microscopy the tumor resembled liver architecture, with polygonal atypical cells in nest formation and trabecular structures. Immunochemistry was positive for alfa-fetoprotein (AFP) and serum AFP was elevated. Hepatoid adenocarcinomas have been reported in multiple organs, being most commonly found in the stomach and the ovaries. Bladder compromise has been rarely described in the literature, and it has been associated with poor prognosis, low remission rates, and early metastasis. PMID:27803830

    Nutrition in older adults on peritoneal dialysis is an important aspect of a patient's clinical management as well as being influenced by their overall well-being, both mental and physical. This is especially pertinent as individuals age, since the potential impact of life changes and physical changes contribute to the development of protein-energy wasting and potentially exacerbating sarcopenia and wasting. This article provides an outline of the nutritional issues to consider in older adults on peritoneal dialysis (PD).

    Discovery of driver mutations in pulmonary adenocarcinoma has revolutionized the field of thoracic oncology with major impact on therapy and diagnosis. Testing for EGFR, ALK, and KRAS mutations has become part of everyday practice. We report a case with multiple synchronous primary pulmonary adenocarcinomas in a 72-year-old female with previous history of smoking. The patient presented with cough and bilateral lung ground glass opacities. A positron emission tomography/computed tomography scan showed no activity in mediastinal lymph nodes. She underwent a left upper lobe biopsy and a right upper lobe wedge resection. Pathology revealed 4 morphologically distinct adenocarcinoma foci, suggestive of synchronous primary lung tumors. Molecular testing demonstrated no mutation in the left tumor. Three different driver mutations were present in the right lung tumors: KRAS codon 12 G12D and G12V and EGFR exon 21 L858R mutation, confirming the initial histologic impression. Subsequently, left upper lobe lobectomy showed 3 additional foci of adenocarcinoma with different morphologies, suggestive of synchronous primaries as well. No additional molecular testing was performed. Synchronous pulmonary adenocarcinomas are not uncommon; however, 4 or more synchronous tumors are rare. Distinguishing multiple primary tumors from intrapulmonary metastases is a common problem in thoracic oncology with major implications for staging, prognosis, and treatment. Lung adenocarcinoma subclassification based on predominant and coexisting histologic patterns can greatly facilitate differentiation between intrapulmonary metastases and multiple synchronous tumors. Use of molecular profiling is recommended since it further increases confidence in the diagnostic workup of multiple pulmonary adenocarcinomas and helps guiding therapy.

    Despite medical advancements, the inflammatory cascade and oxidative stress worsen the prognosis in most cases of peritonitis. Curcumin has emerged as a potential antioxidant and anti-inflammatory agent in few of the acute inflammatory and infective conditions. We examined the effect of intraperitoneal injection of curcumin in endotoxin-induced peritonitis in rats. The blood and peritoneal fluid samples were collected at 3 and 24 h following the induction of peritonitis. Animals were sacrificed at 24 h and the organs preserved. The histopathological report of lung, liver, and intestines in the curcumin-treated rats showed maintenance of tissue architecture to a large extent compared to the control group which showed massive congestion, hemorrhage, and necrosis. The blood and peritoneal fluid total count and differential neutrophil counts were significantly higher at 24 h of induction of peritonitis. Serum amyloid assay and lipid peroxidation were significantly lower, and myeloperoxidase assay was higher in the curcumin-treated group at the end of 24 h; thus, curcumin probably demonstrated a neutrophil-mediated immunopotentiation and anti-inflammatory action thereby protecting the animal from endotoxemia-induced multi-organ damage.

    Peritoneal carcinosis often occurs during the evolution of many neoplasias either abdominal or extra-abdominal. The free time survival of the patients affected by carcinosis is poor (about 6 months) as regards gastric and colorectal cancer. In the last ten-year period a combined surgical technique aiming at the total removal of parietal and visceral peritoneal lesions (peritonectomy) and at the perfusion of peritoneal cavity with chemo-drugs in hyper-thermia had developed. This method is based on the presence of the peritoneal-plasmatic barrier that holds back high molecular weight drugs, keeping from passing at the systemic circulation; in this way it is possible to use higher and more concentrate chemo-drug doses in a very limited area than in the systemic chemotherapy. The association between chemotherapy and hyperthermia produces a synergic effect: hyperthermia, infarct, makes chemo-drugs more effective and selective, improving their capability of penetration in tumoral masses; heat has furthermore an intrinsic anti-neoplastic action, being altered the reparation mechanisms of the tumoral cells. A WEB research on Medline site has been conducted choosing especially those articles referable at the 1999-2000 period. The selected articles have been briefly analysed in the "Clinical experience" section. Authors' experiences have been divided, as far as possible, on the basis of the tumors treatable with cytoreduction and HAPP: 1) Colon-rectal Cancer; 2) Pseudomyxoma peritonei/Appendicular Adenocarcinoma; 3) Gastric Cancer; 4) Ovarian Cancer; 5) Peritoneal Mesothelioma. The determinant variables in the analysis of the results are basically three: 1) Selection of the patients, 2) Characteristics of the surgical operation, 3) Characteristics of the HAPP. Colon-rectal carcinoma: the survival time of the recurrent disease, obtained by some authors like P.H. Sugarbaker, is surely remarkable (50% at 5 years in the patients where a complete cytoreduction was possible to

    Loss of peritoneal function due to peritoneal fibrosing syndrome (PFS) is a major factor leading to treatment failure in chronic peritoneal dialysis (PD) patients. Although the precise biologic mechanisms responsible for these changes have not been defined, the general assumption is that alterations in peritoneal function are related to structural changes in the peritoneal membrane. Studies of the peritoneal membrane by non-invasive ultrasonography (US) in chronic PD patients are limited. The aim of the present study is to assess the relationship between functional parameters of peritoneum and peritoneal thickness measured by US in children treated by chronic PD. We recruited two groups of patients: 23 subjects (13 females, 10 males) on chronic PD (patient group) and 26 (7 females, 19 males) on predialysis out-patient follow-up (creatinine clearance: 20-60 mL/min/1.73 m(2)) (control group). Age, sex, weight, height, body mass index (BMI), chronic PD duration, episodes of peritonitis and the results of peritoneal equilibration test (PET) were recorded. Hemoglobin (Hb), blood pressure (BP), left ventricular mass index (LVMI) and renal osteodystrophy (ROD) parameters were also obtained. The thickness of the parietal peritoneum was measured by trans-abdominal US in all children. Statistical analyses were performed by using Student's t and Pearson's correlation tests. Mean peritoneal thickness in chronic PD patients (1028.26 ± 157.26 μm) was significantly higher than control patients (786.52 ± 132.33). Mean peritoneal thickness was significantly correlated with mean body height (R(2) = 0.93, p < 0.05), BMI (R(2) = 0.25, p < 0.05), chronic PD duration (R(2) = 0.64, p < 0.05), episodes of peritonitis (R(2) = 0.93, p < 0.05), D/Pcreatinine (R(2) = 0.76, p < 0.05) and D4/D0glucose (R(2) = 0.81, p < 0.05).

    Patient: Female, 42 Final Diagnosis: Spontaneous pelvic-abdominal peritonitis due to actinomyces Symptoms: Abdominal distension • abdominal pain • acute abdomen • fever • intermenstrual bleeding • nausea • sepsis • septic shock Medication: — Clinical Procedure: — Specialty: Surgery Objective: Unusual clinical course Background: Pelvic-abdominal actinomycosis is a rare chronic condition caused by an anaerobic, gram-negative rod-shaped commensal bacterium of the Actinomyces species. When Actinomyces becomes pathogenic, it frequently causes a chronic infection with granulomatous abscess formation with pus. Due to diversity in clinical and radiological presentation, actinomycosis can easily be mistaken for several other conditions. Peritonitis without preceding abscess formation caused by Actinomyces species has been described in only few cases before in literature. Case report: We report a case of spontaneous pelvic-abdominal peritonitis with presence of pneumoperitoneum and absence of preceding abscesses due to acute actinomycosis mimicking a perforation of the proximal jejunum in a 42-year-old female with an intra-uterine contraceptive device in place. Explorative laparotomy revealed 2 liters of odorless pus but no etiological explanation for the peritonitis. The intra-uterine contraceptive device was removed. Cultivation showed growth of Actinomyces turicensis. The patient was successfully treated with penicillin. Conclusions: In the case of primary bacterial peritonitis or lower abdominal pain without focus in a patient with an intrauterine device in situ, Actinomyces should be considered as a pathogen.

    Solid tumors are complex and unstructured organs that, in addition to cancer cells, also contain other cell types. Carcinoma-associated fibroblasts (CAFs) represent an important population in the tumor microenviroment and participate in several stages of tumor progression, including cancer cell migration/invasion and metastasis. During peritoneal metastasis, cancer cells detach from the primary tumor, such as ovarian or gastrointestinal, disseminate through the peritoneal fluid and colonize the peritoneum. Tumor cells metastasize by attaching to and invading through the mesothelial cell (MC) monolayer that lines the peritoneal cavity, then colonizing the submesothelial compact zone where CAFs accumulate. CAFs may derive from different sources depending on the surrounding metastatic niche. In peritoneal metastasis, a sizeable subpopulation of CAFs originates from MCs through a mesothelial-to-mesenchymal transition (MMT), which promotes adhesion, invasion, vascularization and subsequent tumor growth. The bidirectional communication between cancer cells and MC-derived CAFs via secretion of a wide range of cytokines, growth factors and extracellular matrix components seems to be crucial for the establishment and progression of the metastasis in the peritoneum. This manuscript provides a comprehensive review of novel advances in understanding how peritoneal CAFs provide cancer cells with a supportive microenvironment, as well as the development of future therapeutic approaches by interfering with the MMT in the peritoneum.

    Objective Peritonitis is the most common life threatening surgical emergency, which requires urgent surgical intervention and is a significant cause of morbidity and mortality. The objective of this study was to highlight the frequency of secondary peritonitis and to analyze the site and causes of perforation, in our tertiary care setup. Methods A retrospective analysis of 311 patients of secondary peritonitis was done from July 2008 to June 2010 at Liaquat University Hospital Jamshoro, Hyderabad, Sindh, Pakistan. All cases found to have peritonitis as a result of perforation of any part of gastrointestinal tract at the time of surgery were included in the study. All cases with either primary peritonitis or that due to anastomotic dehiscence were excluded. Results A total of 311 patients were studied. Most of the patients were males (77%) and (89%) were in the third and fourth decades of life. Majority of the patients presented with pain (97%) associated with bowel symptoms. Most common site of perforation was small bowel (ileal 59%, jujenal 2%). In this series, most common risk factor of perforation was typhoid (43%). Ileostomy was the most commonly performed procedure. Overall morbidity was 48.5% and mortality was 17%. Conclusion Considering the relatively higher rate of typhoid perforation quoted in this study, it is vital that typhoid fever ought to be eliminated by improved sanitation and immunizing programmes, otherwise surgeons will be confronted with its complications.

We present a case of 86-year-old female with metastatic gall bladder adenocarcinoma diagnosed eight months back who presented with generalized fatigue and poor oral intake and was found to be hypercalcemic with elevated parathyroid hormone levels. Imaging with technetium 99 m sestamibi scintigraphy with dual phase, subtraction thyroid scan (dual isotope scintigraphy), magnetic resonance imaging and ultrasonography did not demonstrate any parathyroid lesion in normal or ectopic sites. We believe that the tumor cells were the source of ectopic parathyroid hormone secretion as we had excluded all the other possibilities with extensive combined imaging thereby increasing the sensitivity of our testing. We report the first case of metastatic gall bladder adenocarcinoma with paraneoplastic ectopic parathyroid hormone secretion. PMID:27081650

    We report a patient with supraclavicular lymph node metastasis from an undetectable adenocarcinoma of the transverse colon, who presented with cough and was diagnosed with typhoid fever, bronchitis as well as liver metastasis. There were an abdominal fullness, weight loss, constipation, pencil-like stool with mucous and blood, low-grade fever, bone ache, and tea-color urine. The first colonoscopy revealed lymphocytic ileitis and microscopic findings also showed lymphocytic ileitis. Abdominal USG and CT revealed liver metastasis of unknown origin. Based on the clinical sign and symptoms, we suspected that colorectal carcinoma was the primary site. Then, the second colonoscopy was performed and it revealed a small polyp, which was followed with a biopsy and the result supported a well-differentiated colon adenocarcinoma. Similar result was also revealed by the histopathological evaluation. This is an unusual case of liver and supraclavicular lymph node metastasis arising from a small polyp adenocacinoma of the transverse colon. PMID:26932703

    Adenocarcinoma of the ethmoid sinus is rare, representing only 4 to 8% of malignancies of the paranasal sinuses. An extraordinary case of papillary adenocarcinoma of the ethmoid sinus arising 30 years following high-dose radiotherapy for bilateral retinoblastoma is presented. Histologically, the findings of a papillary pattern of poorly differentiated, mucicarmine-staining cells enclosing gland-like spaces, and the absence of pseudorosettes, melanin, mesenchymal and peripheral neural elements supports an epithelial origin of this tumor. The high incidence of second fatal primary neoplasms in patients with bilateral retinoblastomas receiving radiation suggests an innate susceptibility that may add to the risk of radiotherapy. Careful long-term head and neck surveillance is mandatory if early aggressive management of these extremely lethal tumors is to be successful.

    Peritoneal deterioration causing structural changes and functional decline is a major complication of peritoneal dialysis (PD). The aim of this study was to explore effluent biomarkers reflecting peritoneal deterioration. In an animal study, rats were intraperitoneally administered with PD fluids adding 20 mM methylglyoxal (MGO) or 20 mM formaldehyde (FA) every day for 21 days. In the MGO-treated rats, tenascin-C (TN-C) levels in the peritoneal effluents were remarkably high and a cluster of TN-C-positive mesothelial cells with epithelial-to-mesenchymal transition- (EMT-) like change excessively proliferated at the peritoneal surface, but not in the FA-treated rats. Effluent matrix metalloproteinase-2 (MMP-2) levels increased in both the MGO- and FA-treated rats. In a clinical study at 18 centers between 2006 and 2013, effluent TN-C and MMP-2 levels were quantified in 182 PD patients with end-stage renal disease. Peritoneal function was estimated using the peritoneal equilibration test (PET). From the PET results, the D/P Cr ratio was correlated with effluent levels of TN-C (ρ = 0.57, p < 0.001) and MMP-2 (ρ = 0.73, p < 0.001). We suggest that TN-C in the effluents may be a diagnostic marker for peritoneal deterioration with EMT-like change in mesothelial cells in PD. PMID:26770971

    Background Tuberculosis continues to be an important health problem in the world. Besides pulmonary involvement extrapulmonary involvement becomes an affair in developing countries, even in developed countries. Case presentation A thirty-six year old male patient was admitted with abdominal pain, diarrhea, nausea, vomiting and fever which had started one week before. The patient had been followed up with predialisis Chronic Renal Failure(CRF) diagnosis for 4 years and receiving continuous ambulatory peritoneal dialysis (CAPD) treatment for 4 months. In peritoneal fluid, 1600/mm3 cells were detected and 70% of them were polymorphonuclear leukocytosis. The patient begun nonspesific antibiotherapy but no benefit was obtained after 12 days and peritoneal fluid bacterial cultures remained negative. Peritoneal smear was positive for Asid-fast basilli (AFB), and antituberculosis therapy was started with isoniazid, rifampicine, ethambutol and pyrazinamide. After 15 days his peritoneal fluid cell count was decreased and his symptoms were relieved. Peritoneal fluid tuberculosis culture was found positive. Conclusion Considering this case, we think that in patients with CAPD catheter and peritonitis; when peritoneal fluid leukocytes are high and PMNL are dominant, AFB and tuberculosis culture must be investigated besides bacterial culture routinely.

    Increasing the survival of patients on CAPD is related to the long-term reliability of the peritoneal access. Six silicone Tenckhoff catheters (with strip or diffuse barium sulphate inclusion) removed after 39-69 months because of the appearance of external segment fissures, were analysed by scanning electron microscopy (SEM) and infra-red spectroscopy with attenuated total refractance (ATR). The extracorporeal portion of the catheters showed (by ATR) a more prominent oxidation peak on the external than the internal surface; SEM showed marks and cracks on the external surface and exfoliation and flattening of the silastic reticle on the intraluminal surface. No evidence of oxidation was found in the intra-abdominal portion of the catheters but biofilm was found. We suggest that barium sulphate may render the silastic brittle and physiological and environmental long-term factors (such as uv-rays, temperature, sweat and disinfectants) could cause oxidation and loss of physico-chemical properties, with critical aging of the silastic and loss of catheter resistance to mechanical injury.

    Peritoneal implants were fabricated from poly 2-OH, ethyl methacrylate (HEMA), polyetherurethane (polytetramethylene glycol 1000 MW, 1,4 methylene disocynate, and ethyl diamine), and untreated and sputter treated polytetrafluoroethylene (PTFE). The sputter treated PTFE implants were produced by an 8 cm diameter argon ion source. The treated samples consisted of ion beam sputter polished samples, sputter etched samples (to produce a microscopic surface cone texture) and surface pitted samples (produced by ion beam sputtering to result in 50 microns wide by 100 microns deep square pits). These materials were implanted in rats for periods ranging from 30 minutes to 14 days. The results were evaluated with regard to cell type and attachment kinetics onto the different materials. Scanning electron microscopy and histological sections were also evaluated. In general the smooth hydrophobic surfaces attracted less cells than the ion etched PTFE or the HEMA samples. The ion etching was observed to enhance cell attachment, multinucleated giant cell (MNGC) formation, cell to cell contact, and fibrous capsule formation. The cell responsed in the case of ion etched PTFE to an altered surface morphology. However, equally interesting was the similar attachment kinetics of HEMA verses the ion etched PTFE. However, HEMA resulted in a markedly different response with no MNGC's formation, minimal to no capsule formation, and sample coverage by a uniform cell layer.

    Sphingomonas paucimobilis is an aerobic Gram-negative bacillus found in soil and water. Knowledge regarding the role of this infectious agent is limited because it is rarely isolated from human material. Furthermore, it is an unusual pathogen in cases of peritoneal dialysis (PD)-associated peritonitis. The clinical courses and outcomes of peritonitis caused by S. paucimobilis are variable. Whereas some patients were cured with appropriate antibiotic therapy, others required catheter removal. Cases of PD-associated peritonitis caused by S. paucimobilis have been reported worldwide, and there was a case report of coinfection with S. paucimobilis and Chryseobacterium indologenes in Korea. However, there has been no case caused by S. paucimobilis as a single pathogen. We report a case of PD-associated peritonitis due to S. paucimobilis in which the patient recovered after catheter removal.

    Mesothelial-to-mesenchymal transition (MMT) is an auto-regulated physiological process of tissue repair that in uncontrolled conditions such as peritoneal dialysis (PD) can lead to peritoneal fibrosis. The maximum expression of peritoneal fibrosis induced by PD fluids and other peritoneal processes is the encapsulating peritoneal sclerosis (EPS) for which no specific treatment exists. Tamoxifen, a synthetic estrogen, has successfully been used to treat retroperitoneal fibrosis and EPS associated with PD. Hence, we used in vitro and animal model approaches to evaluate the efficacy of Tamoxifen to inhibit the MMT as a trigger of peritoneal fibrosis. In vitro studies were carried out using omentum-derived mesothelial cells (MCs) and effluent-derived MCs. Tamoxifen blocked the MMT induced by transforming growth factor (TGF)-β1, as it preserved the expression of E-cadherin and reduced the expression of mesenchymal-associated molecules such as snail, fibronectin, collagen-I, α-smooth muscle actin, and matrix metalloproteinse-2. Tamoxifen-treatment preserved the fibrinolytic capacity of MCs treated with TGF-β1 and decreased their migration capacity. Tamoxifen did not reverse the MMT of non-epitheliod MCs from effluents, but it reduced the expression of some mesenchymal molecules. In mice PD model, we demonstrated that MMT progressed in parallel with peritoneal membrane thickness. In addition, we observed that Tamoxifen significantly reduced peritoneal thickness, angiogenesis, invasion of the compact zone by mesenchymal MCs and improved peritoneal function. Tamoxifen also reduced the effluent levels of vascular endothelial growth factor and leptin. These results demonstrate that Tamoxifen is a therapeutic option to treat peritoneal fibrosis, and that its protective effect is mediated via modulation of the MMT process. PMID:23637793

    Primary vulvar adenocarcinomas are very rare. We describe the rare case of primary vulvar apocrine adenocarcinoma, a histologically rare subtype of vulvar adenocarcinoma. A 57-year-old Japanese woman presented with an enlarging vulvar mass. A dark-red, hemorrhagic, ulcerated tumor was on the right side of the anterior labial commissure measuring approximately 3.5 × 3.5 cm. Preoperative biopsy showed poorly differentiated carcinoma with partial differentiation to adenocarcinoma. Systemic examination revealed lymph node metastases in both inguinal regions and no other primary source. We performed radical vulvectomy and bilateral inguinal and pelvic lymphadenectomy. Histopathologic diagnosis was apocrine adenocarcinoma of the vulva with inguinal lymph node metastases, pT1bN2bM0. Surgical margins were negative. The patient received no adjuvant chemotherapy or radiation. Inguinal lymph node recurrence occurred after six months. Reresection and adjuvant tomotherapy were performed. After a further 12 months of observation, no rerecurrence was observed. The patient is now on follow-up. PMID:27668109

    Objective The purpose of this phase II trial was to evaluate the toxicity and antitumor activity of EGEN-001 in platinum resistant recurrent ovarian cancer. Methods Eligible patients had weekly IP infusion of EGEN-001 at a dose of 24 mg/m2. Toxicity and antitumor activity were evaluated using CTCAE and RESIST criteria, respectively. Co-primary endpoints were tumor response and survival without progression (PFS) for at least 6 months. Survival without progression before going onto a subsequent therapy (EFS) for at least six months was also considered. Results A total of 58 EGEN-001 cycles were administered to 20/ 22 enrolled patients (median 2 cycles, range 1–9). The most frequently associated adverse events related specifically to EGEN-001 treatment were grade 1/2 fatigue, fever, chills, abdominal pain, nausea, vomiting, anemia, thrombocytopenia, and leukopenia. Three of 20 EGEN-001 treated patients evaluable for toxicity elected to withdraw from the study motivated in part by grade 1 treatment related toxicities. There were no patients with partial or complete response (0%; 90% CI 0~10.9%). Seven (35%) of 16 patients evaluable for response had stable disease, and 9 (45%) had progressive disease. Six (30%) patients had a PFS of greater than six months, although three had gone off study and onto other therapies before six months. The estimated six-month EFS was 15%. The median PFS and OS was 2.89 and 9.17 months, respectively. Conclusion EGEN-001 at the dose and schedule evaluated was associated with some but limited activity and was seemingly less tolerated in platinum resistant recurrent ovarian cancer patients.

    A major complication in continuous, ambulatory peritoneal dialysis in patients with end-stage renal disease who are undergoing long-term peritoneal dialysis (PD) is peritoneal fibrosis, which can result in peritoneal structural changes and functional ultrafiltration failure. Human umbilical mesenchymal stem cells (HUMSCs) in Wharton's jelly possess stem cell properties and are easily obtained and processed. This study focuses on the effects of HUMSCs on peritoneal fibrosis in in vitro and in vivo experiments. After 24-hour treatment with mixture of Dulbecco's modified Eagle's medium and PD solution at a 1:3 ratio, primary human peritoneal mesothelial cells became susceptible to PD-induced cell death. Such cytotoxic effects were prevented by coculturing with primary HUMSCs. In a rat model, intraperitoneal injections of 20 mM methylglyoxal (MGO) in PD solution for 3 weeks (the PD/MGO 3W group) markedly induced abdominal cocoon formation, peritoneal thickening, and collagen accumulation. Immunohistochemical analyses indicated neoangiogenesis and significant increase in the numbers of ED-1- and α-smooth muscle actin (α-SMA)-positive cells in the thickened peritoneum in the PD/MGO 3W group, suggesting that PD/MGO induced an inflammatory response. Furthermore, PD/MGO treatment for 3 weeks caused functional impairments in the peritoneal membrane. However, in comparison with the PD/MGO group, intraperitoneal administration of HUMSCs into the rats significantly ameliorated the PD/MGO-induced abdominal cocoon formation, peritoneal fibrosis, inflammation, neoangiogenesis, and ultrafiltration failure. After 3 weeks of transplantation, surviving HUMSCs were found in the peritoneum in the HUMSC-grafted rats. Thus, xenografts of HUMSCs might provide a potential therapeutic strategy in the prevention of peritoneal fibrosis. Significance: This study demonstrated that direct intraperitoneal transplantation of human umbilical mesenchymal stem cells into the rat effectively

    We find that colonic adenocarcinoma, which is an extremely rare neoplasm of all animals except man and carcinogen-treated rodents, occurs spontaneously in some marmosets. The cotton-topped Saguinus oedipus oedipus is particularly prone to develop it, but we have found it also at necropsy in Callimico goeldii (Goeldi's marmoset). Numerous metastases to regional lymph nodes develop. The cancers arise de novo in the mucosa and early invade the submucosa and lymphatic apparatus and paracolonic lymph nodes. These findings and the continuing occurrence of this cancer in our colony suggests that the marmoset may be the long-sought primate model for experimental intestinal carcinogenesis.

    The last decade has seen significant developments in the use of combination systemic therapy for advanced pancreatic ductal adenocarcinoma (PDAC), with median survival approaching 1 year for select patients treated with FOLFIRINOX in the metastatic setting. However, it is sobering that these developments have been achieved with the use of traditional cytotoxics rather than from successes in the more modern fields of molecularly targeted therapies or immunotherapy. This article highlights several promising therapeutic approaches to PDAC currently under clinical evaluation, including immune therapies, molecularly targeted therapies, strategies for stromal depletion, and targeted therapy for genetically selected patients.

  5. Oncocytic adenocarcinoma of salivary glands.

    PubMed

    Goode, R K; Corio, R L

    1988-01-01

    Oncocytic adenocarcinoma of salivary gland origin is an extremely rare neoplasm. The diagnosis is established on the basis of oncocytic cellular features in conjunction with dysplastic change. These dysplastic changes may occur in benign oncocytomas or arise de novo. The tumor occurs most commonly in the parotid glands of persons over 60 years of age. Tumors that measure less than 2 cm at the initial surgical procedure appear to have a better prognosis than larger tumors. Aggressive surgical intervention at the initial presentation of the neoplasm, compared to simple enucleation, seems to offer a more favorable prognosis. Recurrence is an ominous feature. Metastasis, when it occurs, is widespread.

    We report a case of acute chylous ascites formation presenting as peritonitis (acute chylous peritonitis) in a patient suffering from acute pancreatitis due to hypertriglyceridemia and alcohol abuse. The development of chylous ascites is usually a chronic process mostly involving malignancy, trauma or surgery, and symptoms arise as a result of progressive abdominal distention. However, when accumulation of "chyle" occurs rapidly, the patient may present with signs of peritonitis. Preoperative diagnosis is difficult since the clinical picture usually suggests hollow organ perforation, appendicitis or visceral ischemia. Less than 100 cases of acute chylous peritonitis have been reported. Pancreatitis is a rare cause of chyloperitoneum and in almost all of the cases chylous ascites is discovered some days (or even weeks) after the onset of symptoms of pancreatitis. This is the second case in the literature where the patient presented with acute chylous peritonitis due to acute pancreatitis, and the presence of chyle within the abdominal cavity was discovered simultaneously with the establishment of the diagnosis of pancreatitis. The patient underwent an exploratory laparotomy for suspected perforated duodenal ulcer, since, due to hypertriglyceridemia, serum amylase values appeared within the normal range. Moreover, abdominal computed tomography imaging was not diagnostic for pancreatitis. Following abdominal lavage and drainage, the patient was successfully treated with total parenteral nutrition and octreotide.

    This report presents two cases of young males who developed the rare idiopathic form of sclerosing encapsulating peritonitis (SEP) presented as partial bowel obstruction, both diagnosed during surgical treatment, with satisfactory outcomes. Sclerosing encapsulating peritonitis is a rare and enigmatic condition, characterized by intraperitoneal fibrosclerosis, which causes intestinal obstruction. It is a chronic entity with a poorly elucidated pathophysiology, leading to the constitution of a thick white nacreous fibrosis membrane that wraps the bowel in a concertina-like fashion with some adhesions configuring an intra-abdominal cocoon. Sclerosing encapsulating peritonitis is reported in a wide variety of patients, including those who have undergone peritoneal dialysis, young adolescent girls, cirrhotic patients after peritoneal-venous shunting, and patients treated with β-blockers. Nevertheless, the etiology of SEP remains obscure. This entity presents many difficulties in preoperative diagnosis because of its peculiar characteristics. Recognition of the SEP results in proper management and prevents unnecessary bowel resection. Regardless of cause, the treatment of the obstruction is surgical, with dissection of the encasing membrane from the intestine and separation of adherent loops of small bowel until they are laid free and returned to their normal configuration. The prognosis after appropriate surgical therapy is good, but depends on coexisting diseases. PMID:21969199

    A new peritoneal dialysate containing pyruvate anions was developed in order to avoid cytotoxic effect of conventional lactate-based dialysate. The dialysate has a final pH of 5.4 to 5.6 and is composed of 1.36-3.86% glucose-monohydrate; 132 mmol/l sodium; 1.75 mmol/l calcium; 0.75 mmol/l magnesium; 102 mmol/l chloride and 35 mmol/l pyruvate. For cytotoxicity testing peritoneal macrophages, and mesothelial cells (MC) were exposed to conventional lactate dialysate, and pyruvate dialysate. We investigated the O2- generation and cytokine synthesis after endotoxin stimulation in peritoneal macrophages and the proliferation of mesothelial cells of cultured human MC. After exposure to lactate dialysate O2- generation and cytokine synthesis in peritoneal macrophages and proliferation of mesothelial cells were inhibited when compared to solution containing pyruvate and the control solution. After preincubation with 3.86% glucose containing solutions, all negative effects became even more pronounced in the lactate group whereas after pre-exposure to pyruvate containing solution the toxic effects were absent. These results suggest that the acute toxic effects of commercially available peritoneal dialysates can be avoided by the use of sodium pyruvate instead of sodium lactate.

    Peritoneal dialysis (PD) is acknowledged worldwide as a well-accepted form of renal replacement therapy (RRT) for end-stage renal disease (ESRD). Ideally, PD should be the preferred modality of RRT for ESRD in developing countries due to its many inherent advantages. Some of these are cost savings (especially if PD fluids are manufactured locally or in a neighboring country), superior rehabilitation and quality of life (QOL), home-based therapy even in rural settings, avoidance of hospital based treatment and the need for expensive machinery, and freedom from serious infections (hepatitis B and C). However, this is not the ground reality, due to certain preconceived notions of the health care givers and governmental agencies in these countries. With an inexplicable stagnation or decline of PD numbers in the developed world, the future of PD will depend on its popularization in Latin America and in Asia especially countries such as China and India, with a combined population of 2.5 billion and the two fastest growing economies worldwide. A holistic approach to tackle the issues in the developing countries, which may vary from region to region, is critical in popularizing PD and establishing PD as the first-choice RRT for ESRD. At our center, we have been pursuing a 'PD first' policy and promoting PD as the therapy of choice for various situations in the management of renal failure. We use certain novel strategies, which we hope can help PD centers in other developing countries working under similar constraints. The success of a PD program depends on a multitude of factors that are interlinked and inseparable. Each program needs to identify its strengths, special circumstances, and deficiencies, and then to strategize accordingly. Ultimately, teamwork is the 'mantra' for a successful outcome, the patient being central to all endeavors. A belief and a passion for PD are the fountainhead and cornerstone on which to build a quality PD program.

    Incidence rates for esophageal adenocarcinoma have increased by over 500% during the past few decades without clear reasons. Gastroesophageal reflux disease (GERD), obesity, and smoking have been identified as risk factors, although the demographic distribution of these risk factors is not consistent with the demographic distribution of esophageal adenocarcinoma, which is substantially more common among whites and males than any other demographic groups. Numerous epidemiological studies have suggested associations between dietary factors and the risks of esophageal adenocarcinoma and its precursor, Barrett’s esophagus, though a comprehensive review is lacking. The main aim of the present review is to consider the evidence linking dietary factors with the risks of esophageal adenocarcinoma, Barrett’s esophagus, and the progression from Barrett’s esophagus to esophageal adenocarcinoma. The existing epidemiological evidence is strongest for an inverse relationship between intake of vitamin C, β-carotene, fruits and vegetables, particularly raw fruits and vegetables and dark-green, leafy and cruciferous vegetables, carbohydrates, fiber and iron and the risk of esophageal adenocarcinoma and Barrett’s esophagus. Patients at higher risk for Barrett’s esophagus and esophageal adenocarcinoma may benefit from increasing their consumption of fruits and vegetables and reducing their intake of red meat and other processed food items. Further research is needed to evaluate the relationship between diet and the progression of Barrett’s esophagus to esophageal adenocarcinoma. Evidence from cohort studies will help determine whether randomized chemoprevention trials are warranted for the primary prevention of Barrett’s esophagus or its progression to cancer. PMID:20624335

The 65-year-old patient was referred for imaging 8 months after pancreaticoduodenectomy and 2 months after completion of a course of chemotherapy. PET/CT showed an FDG-avid omental lesion that suggested peritoneal carcinomatosis. The appearance and evolution at follow-up studies confirmed the diagnosis of omental infarction, a rare complication of pancreatic surgery. This case revealed the possibility of late FDG uptake in omental infarction.

    Peritonitis is a debilitating infectious complication of peritoneal dialysis (PD). Drug-resistant bacterial peritonitis typically has a lower response rate to antibiotics. In the past 15 years, newer antibiotics with activities against drug-resistant Gram-positive bacteria have been developed. In most circumstances, peritonitis due to methicillin-resistant staphylococci responds to vancomycin. If vancomycin cannot be used due to allergy and/or non-susceptibility, there is increasing evidence that linezolid and daptomycin are the drugs of choice. It is reasonable to start linezolid orally or intravenously, but subsequent dose reduction may be necessary in case of myelosuppression. Daptomycin can be given intravenously or intraperitoneally and has excellent anti-biofilm activity. Other treatment options for drug-resistant Gram-positive bacterial peritonitis include teicoplanin, tigecycline and quinupristin/dalfopristin. Teicoplanin is not available in some countries (e.g. the USA). Tigecycline can only be given intravenously. Quinupristin/dalfopristin is ineffective against Enterococcus faecalis and there is only low-quality evidence to support its efficacy in the treatment of peritonitis. Effective newer antibiotics against drug-resistant Gram-negative bacteria are lacking. Polymyxins can be considered, but evidence on its efficacy is limited. In this review, we will discuss the potential use of newer antibiotics in the treatment of drug-resistant bacterial peritonitis in PD patients. PMID:27478608

    Abstract Duodenal adenocarcinoma, a very rare malignant gastrointestinal tumor, mainly metastasizes via the lymphatic system. Metastases from duodenal adenocarcinomas to the breast are very uncommon. A 31-year-old woman presented at our department with a left breast tumor. She had a past medical history of duodenal adenocarcinoma. Physical examination on admission confirmed a 2.5-cm-diameter tumor in the outer lower quadrant of the left breast. Computed tomography (CT) examination showed a soft lesion with tissue-like density and enlarged axillary lymph nodes. Local excision was performed to remove the breast lesion. The findings of cytologic, histologic, and immunohistochemistry examination indicated a breast metastasis from the previous duodenal adenocarcinoma. The patient was treated with palliative chemotherapy. Metastases from duodenal adenocarcinoma to the breast are rare. The diagnosis depends on medical history, imaging, and pathologic examination including immunohistochemistry. An accurate diagnosis is important to avoid unnecessary surgery. PMID:26986146

    Sinonasal adenocarcinomas are rare, locally invasive tumours. In this case the symptomatic profile was unusual and the diagnosis was missed at the primary care stage. Interestingly this would be the first documented case with an absent ipsilateral olfactory bulb. A 55-year old male presented with symptoms of behavioural change and mild headaches. He was later found to have a large Sinonasal adenocarcinoma which penetrated the skull base. This was treated by a combined craniotomy and endonasal approach. Sinonasal adenocarcinomas are unusual tumours and further research is required in order to clarify management strategies and prognosis. This interesting case was more unusual again given its presentation, extent and absence of the olfactory bulb. Importantly for primary care physicians the initial diagnosis was considered psychiatric rather than organic; despite there being specific features of the presentation which were suggestive of an intra-cranial lesion.

    Introduction. With the improving survival of cancer patients, the development of a secondary primary cancer is an increasingly common phenomenon. Extensive surgery during initial treatment may pose significant challenges to surgeons managing the second primary cancer. Case Presentation. A 69-year-old male, who had a pancreaticoduodenectomy three years ago for pancreatic head adenocarcinoma, underwent an uneventful extended total gastrectomy for gastroesophageal junctional adenocarcinoma. The reconstruction controversies and considerations are highlighted. Discussion. Genetic, environmental, and lifestyle factors are common for several gastrointestinal malignancies. However, the occurrence of a second unfavorable cancer such as gastroesophageal adenocarcinoma after pancreatic head cancer treatment is extremely uncommon. This clinical scenario possesses numerous difficulties for the surgeon, since surgical resection is the mainstay of treatment for both malignancies. Gastrointestinal reconstruction becomes challenging and requires careful planning and meticulous surgical technique along with sound intraoperative judgement.

    Sinonasal adenocarcinomas are rare, locally invasive tumours. In this case the symptomatic profile was unusual and the diagnosis was missed at the primary care stage. Interestingly this would be the first documented case with an absent ipsilateral olfactory bulb. A 55-year old male presented with symptoms of behavioural change and mild headaches. He was later found to have a large Sinonasal adenocarcinoma which penetrated the skull base. This was treated by a combined craniotomy and endonasal approach. Sinonasal adenocarcinomas are unusual tumours and further research is required in order to clarify management strategies and prognosis. This interesting case was more unusual again given its presentation, extent and absence of the olfactory bulb. Importantly for primary care physicians the initial diagnosis was considered psychiatric rather than organic; despite there being specific features of the presentation which were suggestive of an intra-cranial lesion.

    Primary retroperitoneal serous adenocarcinoma is an extremely rare clinical entity, with only five cases previously reported. We describe a 66-year-old woman with serous adenocarcinoma arising from the retroperitoneum, adhesive to the ileocecum. On MRI, the tumor was 17 x 10 x 6 cm in size and monocystic. The tumor cells were positive for CA125, estrogen receptor, and Wilms tumor 1, and were differentiated from enterogenic cyst by the presence of cytokeratin 7 (+), and the absence of cytokeratin 20 (-). Simultaneously, uterine adnexal serous adenocarcinoma was detected. The volume of the retroperitoneal tumor was 14 times larger than that of the uterine adnexal tumor. We suggest the possibility that the retroperitoneal cancer arose as a primary cancer from rests of the müllerian epithelium synchronously with the uterine adnexal cancer. The patient had been taking conjugated estrogen for 10 years, suggesting that long-term estrogen stimulation may have contributed to the progression of the tumors.

    We provided partial peritoneal alimentation to a 1.69-kg 11-month-old premature infant who had no available central venous access, depleted peripheral venous access, and gastrointestinal dysfunction. A cuffed silastic catheter was surgically inserted into the suprahepatic space. An alimentation solution was continuously infused into the peritoneum for 28 days to supplement peripheral venous and nasogastric alimentation and contributed 42 +/- 15% of total calories daily. Weight gain was achieved, but complications included hypoglycemia, hypophosphatemia, intravascular dehydration, catheter site leakage, ascites, and hydrocele. At autopsy 11 months later, lipid accumulation was present in the upper peritoneum and the hilar regions of the lungs secondary to preexisting lymphatic obstruction. Partial peritoneal alimentation may be feasible when other access routes are inadequate, but lymphatic obstruction is a contraindication to the peritoneal administration of lipid emulsions.

    Objective. This study reviews the relevant publications on the clinical effects of icodextrin in peritoneal dialysis (PD). Design. The study provides a systematic review of the literature (MEDLINE search with icodextrin as the keyword). Results. Icodextrin induces sustained transcapillary ultrafiltration during long dwell periods. It also stimulates increased removal of sodium by the peritoneal membrane, reduction of extracellular water (ECW) and total body water (TBW). Effects of icodextrin on blood pressure control and residual renal function are discrepant. Icodextrin induces a reduction in the formation of advanced glycation end-products, while the longitudinal changes in the peritoneal membrane transport are less prominent. Conclusions. Use of icodextrin in PD improves the sodium and fluid balance. Icodextrin is potentially more biocompatible, when compared with the conventional glucose solutions. The side effects are rare.

    We describe a very rare case of chronic peritonitis with secondary adhesive intestinal obstruction caused by Sphingomonas paucimobilis in a healthy 28-year-old Chinese man. This bacillus has not been described as a cause of spontaneous peritonitis in healthy people. It was an asymptomatic, generalized, and slow-growing peritonitis causing peritoneal adherens and at the end intestinal occlusion that needed surgical adhesiolysis.

    Pulmonary enteric adenocarcinoma (PEAC), a extremely rare variant of primary invasive adenocarcinoma of the lung, was recognized by the international multidisciplinary classification of lung adenocarcinoma which was proposed by the International Association for the Study of Lung Cancer (IASLC), the American Thoracic Society (ATS), and the European Respiratory Society (ERS) published in early 2011. Histologically, PEAC is considered to be mainly composed of tall columnar cells arranged in an irregular glandular cavity or cribriform pattern with extensive central necrosis which show high resemblance to that of intestinal epithelia and colorectal carcinomas. Immunohistochemically, PEAC can not only expresses typical proteins common to lung primaries but is positive for at least one intestinal markers, such as CDX2, cytokeratin (CK) 20, MUC2, therefore, the differentiation of primary PEACs from metastatic colorectal cancers can be challenging. In this study, we report 9 cases of PEAC and a panel of immunohistochemical protein markers of CK7, CK20, thyroid transcription factor 1 (TTF-1), Napsin A, MUC2 and villin was analyzed with the comparison of 20 metastatic colorectal carcinomas (MCRs), and 20 typical primary adenocarcinomas (tPACs). As was expected, CK7 expression was documented in all 9 PEACs and 20 tPCAs while CK20 was significantly more prevalent in adenocarcinoma that originated from colorectal. Additionally, we evaluate the classical mutations of EGFR, KRAS in the 9 cases of PEACs, it turned out that all tumors were EGFR-wild and KRAS-wild types, which confirmed that PEAC has a separate phenotype from usual pulmonary adenocarcinoma.

    Streptomyces organisms are soil inhabitants rarely causing nonmycetomic infections. We describe a case of secondary peritonitis caused by Streptomyces viridis in a chronic alcoholic patient who presented with fever, abdominal distension, and pain in the abdomen. The most likely source of infection was by inoculation through multiple paracenteses, done for treatment of ascites, before the patient came to our health care center. This is the second case report of Streptomyces peritonitis and the first case caused by Streptomyces viridis, which is usually found in the soil in our geographic region. PMID:22337982

    The ventriculoperitoneal (VP) shunt is a common procedure in pediatric neurosurgery that carries a risk of complications at cranial and abdominal sites. We report on the case of a child with shunt infection and malfunction. The peritoneal catheter was tethered within the abdominal cavity, precluding its removal. Subsequently, laparoscopic exploration identified a knot at the distal end of the peritoneal catheter around the omentum. A new VP shunt was inserted after the infection was healed. This type of complication occurs rarely, so there are a limited number of case reports in the literature. This report is complemented by a literature review. PMID:24109528

    Spontaneous bacterial peritonitis is a well-known complication of cirrhosis; however, spontaneous fungal peritonitis (SFP) is less well-recognised and described. Our objective was to determine the clinical characteristics, treatment outcomes and factors associated with death among patients with SFP. We performed a retrospective cohort study using the primary outcome of all-cause mortality at 28 days. Twenty-five patients were included; Candida species were the causative pathogen in all cases. At the onset of SFP, patients were critically ill, median APACHE II and MELD scores were 22 and 30.3, respectively. The 28-day mortality rate was 56%; six patients died prior to culture positivity. Among the remaining patients, there were no differences in rates of death by treatment regimen (P = 0.55). APACHE II score at the onset of SFP was an independent predictor of death (OR = 1.46, 95% CI = 1.02-2.08, P = 0.04). In conclusion, SFP develops among critically ill patients with cirrhosis and is associated with high rates of death. Directed antifungal therapy did not improve patient outcomes. Future studies assessing the benefit of early or pre-emptive antifungal therapy are warranted.

    The study was designed to explore the psychosocial effects on caretakers of children in Taiwan on chronic peritoneal dialysis (CPD). This is a case-control study, performed with subjects drawn from eight medical centers. The study group consisted of caretakers of 32 children with renal failure being treated with CPD. For comparison, a control group of caretakers of 64 healthy children as well as the regional Taiwanese studies were used. Two instruments were used to explore the presence of probable depression and quality of life (QOL) of the caretakers: the Taiwanese Depression Questionnaire, and the World Health Organization QOL BRIEF-Taiwan Version. In the study group, only 25% of caregivers had full-time jobs, and 66% of families had an annual income of less than US dollar 15,000. Of the 32 families in the study group, 16% had only a single parent. The prevalence of probable depression was significantly more common in the study group compared with control and referent group (28% vs 5% and 9.44%; P = 0.001). QOL scores in four domains were also significantly lower in the study group. In conclusion, even with the advances of peritoneal dialysis techniques, caring for children on CPD in Taiwan has significant adverse psychosocial effects on the primary caregivers. Attention should be paid to the psycho-social status of the caregivers. PMID:16985519

    Adenocarcinomas exhibiting gastric differentiation represent a recently described and uncommon subtype of non-human papillomavirus (HPV)-related cervical adenocarcinoma. They comprise a spectrum from a well-differentiated variant (adenoma malignum/mucinous variant of minimal deviation adenocarcinoma) to a more poorly differentiated overtly malignant form, generally referred to as gastric-type adenocarcinoma. Rarely, such tumors have also been described as primary vaginal neoplasms. Gastric-type adenocarcinomas exhibit considerable morphologic overlap with adenocarcinomas originating outside the female genital tract, especially mucinous adenocarcinomas arising in the pancreas and biliary tract. Moreover, they often metastasize to unusual sites, such as the ovary and peritoneum/omentum, where they can be mistaken for metastatic adenocarcinomas from other, nongynecologic sites. There is little information regarding the immunophenotype of gastric-type adenocarcinomas, and knowledge of this is important to aid in the distinction from other adenocarcinomas. In this study, we undertook a detailed immunohistochemical analysis of a large series of cervical (n=45) and vaginal (n=2) gastric-type adenocarcinomas. Markers included were cytokeratin (CK)7, CK20, CDX2, carcinoembryonic antigen, CA125, CA19.9, p16, estrogen receptor, progesterone receptor, MUC6, PAX8, PAX2, p53, hepatocyte nuclear factor 1 beta, carbonic anhydrase IX, human epidermal receptor 2 (HER2), and mismatch repair (MMR) proteins. All markers were classified as negative, focal (<50% of tumor cells positive), or diffuse (≥50% tumor cells positive) except for p53 (classified as "wild-type" or "mutation-type"), HER2 (scored using the College of American Pathologists guidelines for gastric carcinomas), and MMR proteins (categorized as retained or lost). There was positive staining with CK7 (47/47-45 diffuse, 2 focal), MUC6 (17/21-6 diffuse, 11 focal), carcinoembryonic antigen (25/31-12 diffuse, 13 focal

    Here the authors report a case of refractory peritonitis leading to multiple hospitalizations and the loss of peritoneal dialysis access in a patient on automated peritoneal dialysis, caused by Asaia bogorensis, a bacterium not previously described as a human pathogen. This organism was identified by sequence analysis of the 16S ribosomal RNA gene. Unusual microbial agents may cause peritonitis, and molecular microbiological techniques are important tools for identifying these agents.

    We report the first documented case of ovarian metastasis from a jejunal primary adenocarcinoma in an Australian patient. The presentation was unusual, initially a suspicious abdominal nodule in the epigastric area, which turned out to be an adenocarcinoma of possible intestinal origin. Gastroscopy and colonoscopy were performed with no suspicious lesion identified. Abdominal and pelvic ultrasound imaging showed a complex pelvic mass suspicious of ovarian cancer. Laparoscopy was performed to exclude possibility of ovarian cancer and small bowel cancer. The ovarian mass showed similar features from the epigastric nodule, again suggestive of intestinal primary. Definitive diagnosis was obtained when the patient represented 2 months later with malignant bowel obstruction requiring palliative resection of the proximal jejunum. This case demonstrates the difficulty in diagnosing ovarian metastasis from a small bowel primary, which has the potential to mimic an ovarian primary tumour clinically, and a large bowel or ovarian primary pathologically.

    Endometriosis generally occurs in the ovary. Intestinal endometriosis is rare. About 1 % of all endometriosis cases become malignant. Malignant transformation of small intestinal endometriosis is very rare. A 55-year-old woman who underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy and omentectomy for endometriosis 7 years ago presented to her primary care doctor with melena. A tumor was detected in the right lower abdomen by ultrasonography. The doctor referred her to our hospital. Computed tomography demonstrated a lobulated tumor ventral to the right common iliac vessels. Magnetic resonance imaging demonstrated that the tumor had heterogeneous intensity on T2-weighted images. Several small cysts with high intensity were observed caudal to the tumor on T2-weighted images. We performed partial small intestinal resection for the lesion. The tumor was diagnosed as endometrioid adenocarcinoma of the small intestine. She has been relapse-free for 5 years after surgery. Only three cases of malignant transformation of small intestinal endometriosis have been reported previously. It is very rare for long-term survival to be obtained with surgery alone, as in our case. This case report highlights the imaging findings for malignant transformation of intestinal endometriosis. PMID:27624553

    Gastric cancer is a leading cause of cancer deaths, but analysis of its molecular and clinical characteristics has been complicated by histological and aetiological heterogeneity. Here we describe a comprehensive molecular evaluation of 295 primary gastric adenocarcinomas as part of The Cancer Genome Atlas (TCGA) project. We propose a molecular classification dividing gastric cancer into four subtypes: tumours positive for Epstein–Barr virus, which display recurrent PIK3CA mutations, extreme DNA hypermethylation, and amplification of JAK2, CD274 (also known as PD-L1) and PDCD1LG2 (also knownasPD-L2); microsatellite unstable tumours, which show elevated mutation rates, including mutations of genes encoding targetable oncogenic signalling proteins; genomically stable tumours, which are enriched for the diffuse histological variant and mutations of RHOA or fusions involving RHO-family GTPase-activating proteins; and tumours with chromosomal instability, which show marked aneuploidy and focal amplification of receptor tyrosine kinases. Identification of these subtypes provides a roadmap for patient stratification and trials of targeted therapies. PMID:25079317

    Peritoneal catheter dysfunction is a significant complication of VP shunting in children. Improvement in technique and material should reduce complications such as detachment and breakage. Shunt infection, even if subclinical, should be suspected as the cause of early peritoneal catheter obstruction, especially if recurrent, as well as in cases of organ perforation. Cultures, prolonged if necessary, should be taken and infection should be treated prior to shunt revision. We have had no recurrence of infection or peritoneal catheter dysfunction after treatment with exteriorization of the infected shunt, antibiotic therapy and insertion of a new shunt on the contralateral side. In infected cases antibiotic therapy, both pre- and intra-operatively, should be a matter of course. With these precautions a better result with the ventriculo-peritoneal shunt should be achieved.

    Case-report of protozoal infection (Blastocystis bominis) during Pseudomonas peritonitis in male patient with intestinal diverticulosis on continuous ambulatory peritoneal dialysis (CAPD) treatment for chronic renal failure (CRF). Microscopic morphology and cultural characteristics are summarized from current literature. Photographic images in phase contrast from fresh-observation of faeces and peritoneal fluid are reported. Although other Protozoa (e.g. Acanthamoeba free-living) have already been found in dialysis fluid, this is the first case, referred in literature, of Blastocystis bominis infection in CAPD patients. Some pathogenetic hypothesis are done involving Blastocystis bominis in peritoneal infection, especially in immunodepressed patients like dialysed ones. Although many chemotherapeutics are provided for this protozoiasis during enteritis, in our case no supplement was required except specific antibiotic therapy for Pseudomonas infection. Symbion or pathogen? Is now-a-day the question which troubles parasitologists. Systemic research of Protozoa in dialysed patients is anyhow advisable. PMID:8848771

    Rothia muciliaginosa (R. mucilaginosa) is a facultative, Gram-positive coccus that is considered to be part of the normal flora of the mouth and respiratory tract. There are sporadic reports of the organism causing endocarditis in patients with heart valve abnormalities, as well as meningitis, septicemia, and pneumonia associated with intravenous drug abuse. However, it is an unusual pathogen in cases of peritoneal dialysis (PD)-associated peritonitis. Although R. mucilaginosa is generally susceptible to penicillin, ampicillin, cefotaxime, imipenem, rifampicin, and glycopeptides, there are no guidelines for the treatment of PD-associated peritonitis. Herein, we report a case of PD-associated peritonitis due to R. mucilaginosa that was resolved with intraperitoneal antibiotic treatment. PMID:26484045

    A 33-year-old Caucasian man with end-stage renal disease secondary to biopsy-proven IgA nephropathy, managed with continuous ambulatory peritoneal dialysis (PD), presented with PD-related peritonitis, the causal organism being a non-branching Gram-positive bacillus, Rhodococcus equi. Initial empirical Gram positive and negative coverage with cefazolin and ceftazidime was unsuccessful, but following isolation of the organism, and conversion to intraperitoneal vancomycin and oral ciprofloxacin, the peritonitis episode resolved. At day 10, vancomycin was switched to azithromycin for a total of 6 weeks of antimicrobial therapy. The PD catheter was preserved, and the patient remained peritonitis-free at 6 months of follow-up.

    Intra-abdominal infection is one of the major causes of septic shock and multiple organ failure. To date, what causes the disease's progression remains unclear and therefore the relevance of immune modulating therapies remains speculative. The primary outcome measure of this study was to investigate immune modulating mediators at the onset of peritonitis before the development of subsequent septic shock. The secondary outcome measure was to investigate the usefulness of these immune parameters in predicting progression from peritonitis to septic shock. Fifty-eight peritonitis patients were included in this study: 14 patients subsequently developed septic shock. All patients were examined on "diagnosis of peritonitis" (<4 h within establishment of diagnosis), during "early septic shock" (<12 h following the onset of septic shock), and once again during "late septic shock" (within 72-98 h following the onset of septic shock). The immune modulating parameters tumor necrosis factor-alpha (TNF-alpha), the soluble TNF-alpha receptors I and II (sTNF-alpha RI and sTNF-alpha RII), interleukines (IL) -1beta, -6, -8, and -10, and the adhesions molecules endothelial-leukocyte-adhesion-molecule (E-Selectin), intercellular-adhesion-molecule-1 (ICAM-1), and vascular-adhesion-molecule-1 (VCAM-1), in addition to nitrate and nitrite, were determined. In the peritonitis group with subsequent septic shock, TNF-alpha, sTNF-alpha RI + RII IL-1beta, IL-8, IL-10, and nitrate were significantly increased before the onset of septic shock. TNF-alpha had an area under the receiver operating characteristics curve (AUC) of 0.84 and was reliable in predicting the progression from peritonitis to septic shock. The AUC of the other immune modulating parameters, despite being significantly elevated, ranged from 0.71 to 0.76. The AUC of the conventional laboratory markers such as leukocytes and C-reactive protein ranged from 0.64 to 0.68. In peritonitis that progressed to septic shock, an early

    Purpose To analyze the complications and costs of minilaparotomies performed by a nephrologist (group A) compared with conventional laparotomies performed by a surgeon (group B) for peritoneal catheter implantation. Setting Two university hospitals (Santa Sofia and Caldas) in Manizales, Caldas, Colombia. Methods The study included stage 5 chronic kidney disease patients, with indication of renal replacement therapy, who were candidates for peritoneal dialysis and gave informed consent for a peritoneal catheter implant. Minilaparotomies were performed by a nephrologist in a minor surgery room under local anesthesia. Conventional laparotomies were performed by a surgeon in an operating room under general anesthesia. Results Two nephrologists inserted 157 peritoneal catheters, and seven general surgeons inserted 185 peritoneal catheters. The groups had similar characteristics: the mean age was 55 years, 49.5% were men, and the primary diagnoses were diabetic nephropathy, hypertensive nephropathy, and unknown etiology. The implant was successful for 98.09% of group A and 99.46% of group B. There was no procedure-related mortality. The most frequent complications in the first 30 days postsurgery in group A versus group B, respectively, were: peritonitis (6.37% versus 3.78%), exit-site infection (3.82% versus 2.16%), tunnel infection (0% versus 0.54%), catheter entrapment by omentum (1.27% versus 3.24%), peritoneal effluent spillover (1.91% versus 2.16%), draining failure (4.46% versus 6.49%), hematoma (0% versus 1.08%), catheter migration with kinking (3.18% versus 2.70%), hemoperitoneum (1.27% versus 0%), and hollow viscera accidental puncture (1.91% versus 0.54%). There were no statistically significant differences in the number of complications between groups. In 2013, the cost of a surgeon-implanted peritoneal dialysis catheter in Colombia was US $366 (666,000 COP), whereas the cost of a nephrologist-implanted catheter was US $198 (356,725 COP).

    During continuous ambulatory peritoneal dialysis (CAPD), peritoneal host defence mechanisms are repeatedly exposed to dialysis solutions (with unphysiological composition) which may compromise peritoneal immune cell functions. In this context, the current study focused on the capacity of peripheral and peritoneal PMN to release leukotrienes following exposure to conventional CAPD dialysates. PMN were obtained from peripheral blood of healthy volunteers and from the peritoneal effluent of CAPD patients with acute peritonitis. Following isolation, cells were incubated in fresh CAPD dialysates or control buffer, and calcium ionophore A23187-stimulated leukotriene synthesis was measured. Additional experiments included RP-HPLC analysis and radioactivity monitoring of lipoxygenase products in PMN labelled with 14C-arachidonic acid. Leukotriene B4 and leukotrienes C4/D4/E4 were determined by radioimmunoassay. Ionophore-triggered leukotriene release from cells exposed to control buffer was pronounced in inflammatory peritoneal PMN (70.4 +/- 31.3 ng/5 x 10(6) cells LTB4 and 13.4 +/- 19.8 ng/5 x 10(6) cells LTC4/D4/E4, mean +/- SD, n = 14) when compared to healthy peripheral PMN (26.6 +/- 16.9 ng/ml LTB4 and 6.3 +/- 6.6 ng/ml LTC4/D4/E4, n = 12). Incubation in fresh solutions for peritoneal dialysis severely depressed leukotriene release from both cell populations. These results indicate a severe inhibition of cellular responsiveness as a consequence of dialysate exposure which could contribute to the impairment of host defence early in the CAPD cycle.

    Comamonas testosteroni (C. testosteroni) has been rarely observed as an infectious agent in clinical practice. Few reports described its potential pathogenicity in bloodstream and abdominal infections. Here, we report our experience in the treatment of a C. testosteroni-associated peritonitis in a four-year-old girl receiving chronic peritoneal dialysis (PD). The organism was shown to be highly susceptible to appropriate antibiotic therapy. Infection responded promptly and the patient was managed conservatively without withdrawal from PD.

    OBJECTIVE: The authors' aim was to review the clinical features and estimate the long-term survival of patients with colorectal carcinoma complicating Crohn's disease. SUMMARY BACKGROUND DATA: Recent studies have demonstrated a significantly increased risk of colorectal carcinoma in patients with Crohns disease. METHODS: The authors reviewed retrospectively the medical records of 30 patients with Crohn's disease admitted to The Mount Sinai Hospital between 1960 and 1989 in whom colorectal adenocarcinoma developed. All patients were operated on and follow-up was complete for all patients to 10 years after operation, to the time of death, or to the closing date of the study in December 1989. RESULTS: The 30 patients in the series had 33 colorectal adenocarcinomas; three patients (10%) presented with two synchronous cancers. The patients were relatively young (mean age, 53 years) and had long-standing Crohn's disease (duration >20 years in 87%). The 5-year actuarial survival was 44% for the overall series: 100% for stage A, 86% for stage B, 60% for stage C. All five patients with excluded bowel tumor died of large bowel cancer within 2.4 years; by contrast, the actuarial 5-year survival for patients with in-continuity tumors was 56%. CONCLUSIONS: The incidence, characteristics, and prognosis of colorectal carcinoma complicating Crohn's disease are similar to the features of cancer in ulcerative colitis, including young age, multiple neoplasms, long duration of disease, and greater than a 50% 5-year survival rate (without excluded loops). These observations suggest the advisability of surveillance programs for Crohn's disease of the colon similar to those for ulcerative colitis of comparable duration and extent. PMID:8597513

    BACKGROUND: Pasteurella species are Gram-negative coccobacilli that are a part of the normal oropharyngeal flora of numerous domestic animals. They have been recognized as a rare but significant cause of peritonitis in patients undergoing peritoneal dialysis (PD). A consensus about management strategies for PD-associated peritonitis caused by Pasteurella species currently does not exist. METHODS: The microbiological database serving the Manitoba Renal Program was searched from 1997 to 2013 for cases of Pasteurella species PD-associated peritonitis, and charts were reviewed. PubMed was searched for case reports and data were abstracted. RESULTS: Seven new local cases and 30 previously reported cases were analyzed. This infection is clinically similar to other forms of PD peritonitis, with household pet exposure appearing to be the strongest risk factor. Cats are the most commonly implicated pet. Direct contact between the pet and the equipment was commonly reported (25 of 37 patients) but was not necessary for infection to develop. The mean duration of treatment was 15 days. Complication rates were low, with only 11% of patients requiring PD catheter removal. There was no mortality reported. CONCLUSION: Pasteurella species are a rare cause of PD-associated peritonitis that can be successfully treated with a two-week course of intraperitoneal antibiotics with a high likelihood of catheter salvage.

  20. Peritoneal adhesions after laparoscopic gastrointestinal surgery

    PubMed Central

    Mais, Valerio

    2014-01-01

    Although laparoscopy has the potential to reduce peritoneal trauma and post-operative peritoneal adhesion formation, only one randomized controlled trial and a few comparative retrospective clinical studies have addressed this issue. Laparoscopy reduces de novo adhesion formation but has no efficacy in reducing adhesion reformation after adhesiolysis. Moreover, several studies have suggested that the reduction of de novo post-operative adhesions does not seem to have a significant clinical impact. Experimental data in animal models have suggested that CO2 pneumoperitoneum can cause acute peritoneal inflammation during laparoscopy depending on the insufflation pressure and the surgery duration. Broad peritoneal cavity protection by the insufflation of a low-temperature humidified gas mixture of CO2, N2O and O2 seems to represent the best approach for reducing peritoneal inflammation due to pneumoperitoneum. However, these experimental data have not had a significant impact on the modification of laparoscopic instrumentation. In contrast, surgeons should train themselves to perform laparoscopy quickly, and they should complete their learning curves before testing chemical anti-adhesive agents and anti-adhesion barriers. Chemical anti-adhesive agents have the potential to exert broad peritoneal cavity protection against adhesion formation, but when these agents are used alone, the concentrations needed to prevent adhesions are too high and could cause major post-operative side effects. Anti-adhesion barriers have been used mainly in open surgery, but some clinical data from laparoscopic surgeries are already available. Sprays, gels, and fluid barriers are easier to apply in laparoscopic surgery than solid barriers. Results have been encouraging with solid barriers, spray barriers, and gel barriers, but they have been ambiguous with fluid barriers. Moreover, when barriers have been used alone, the maximum protection against adhesion formation has been no greater than

    Background Prevalence of moderate to severe cognitive impairment among hemodialysis patients is more than double the prevalence in the general population. This study describes cognitive impairment occurrence in a peritoneal dialysis cohort compared with a cohort without chronic kidney disease (CKD). Study Design Cross-sectional study. Setting and Participants 51 English-speaking peritoneal dialysis patients from two urban dialysis units, compared with 338 hemodialysis patients from 16 urban dialysis units and 101voluntary controls without CKD from urban general medicine clinics. Predictor A 45-minute battery of nine validated neuropsychological tests (cognitive domains memory, executive function, language). Outcomes Mild, moderate, or severe cognitive impairment, classified according to a previously designed algorithm. Results Of the peritoneal dialysis cohort, 33.3% had no or mild, 35.3% moderate, and 31.4% severe cognitive impairment; corresponding values were 60.4%, 26.7%, and 12.9% of the non-CKD cohort, and 26.6%, 36.4%, and 37.0% of the hemodialysis cohort. A logistic regression model including age, sex, race, education, hemoglobin, diabetes, and stroke showed that only non-white race (P = 0.002) and education (P = 0.002) were associated with moderate to severe cognitive impairment in the peritoneal dialysis cohort. Compared with hemodialysis patients, more peritoneal dialysis patients had moderate to severe memory impairment (60% vs. 52%), but fewer had impaired executive function (one-third vs. one-half). Peritoneal dialysis was associated with a more than 2.5-fold increased risk of moderate to severe cognitive impairment compared with no CKD (OR, 2.58; 95% confidence interval 1.02-6.53), as was hemodialysis (OR, 3.16; 95% CI, 1.91-5.24), in an adjusted logistic regression model. Limitations Small sample size, participation rate somewhat low. Conclusions Similar to hemodialysis patients, two-thirds of peritoneal dialysis patients had moderate to severe

    BACKGROUND Pelvic-abdominal actinomycosis is a rare chronic condition caused by an anaerobic, gram-negative rod-shaped commensal bacterium of the Actinomyces species. When Actinomyces becomes pathogenic, it frequently causes a chronic infection with granulomatous abscess formation with pus. Due to diversity in clinical and radiological presentation, actinomycosis can easily be mistaken for several other conditions. Peritonitis without preceding abscess formation caused by Actinomyces species has been described in only few cases before in literature. CASE REPORT We report a case of spontaneous pelvic-abdominal peritonitis with presence of pneumoperitoneum and absence of preceding abscesses due to acute actinomycosis mimicking a perforation of the proximal jejunum in a 42-year-old female with an intra-uterine contraceptive device in place. Explorative laparotomy revealed 2 liters of odorless pus but no etiological explanation for the peritonitis. The intra-uterine contraceptive device was removed. Cultivation showed growth of Actinomyces turicensis. The patient was successfully treated with penicillin. CONCLUSIONS In the case of primary bacterial peritonitis or lower abdominal pain without focus in a patient with an intra-uterine device in situ, Actinomyces should be considered as a pathogen.

    Mammary-like adenocarcinoma of the vulva associated to Paget's disease is exceedingly rare. So, it is very important to perform all the pathological and immunohistochemical investigations to achieve differential diagnosis from both a metastatic lesion from an orthotopic breast cancer and a vulvar adnexal tumor. This report describes a case of vulvar Paget's disease associated with underlying mammary-like adenocarcinoma diagnosed in the Department of Obstetrics and Gynecology of Farhat Hached university hospital of Sousse in Tunisia. We also review previously reported cases of primary breast-like carcinoma of the vulva with or without Paget's disease.

    Occurring either synchronously or metachronously to the primary tumor, peritoneal metastases (PM) are diagnosed in 8 to 20 % of the patients with colorectal cancer (CRC). Prognosis of these patients appears to be worse than those with other sites of metastases. While systemic therapy has shown significant prolongation of survival in patients with stage IV colorectal cancer, the outcomes in the subset of patients with PM has been much inferior. Over the last 2 decades, cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) have been effective in substantially prolonging survival in patients with colorectal PM and have the potential to cure certain patients as well. This article reviews the current evidence for CRS and HIPEC to treat colorectal PM as well as future research going on in this form of locoregional treatment. PMID:27065708

    INTRODUCTION Intestinal metastasis from gastric cancer is rare, although the most common cause of secondary neoplastic infiltration of the colon is gastric cancer. However, little data is available on recurrence or death in patients with gastric cancer surviving >5 years post-gastrectomy. Here we report two cases of lower intestinal metastasis from gastric cancer >5 years after primary resection and discuss with reference to the literature. PRESENTATION OF CASE Case 1: A 61-year-old man with a history of total gastrectomy for gastric cancer 9 years earlier was referred to our hospital with constipation and abdominal distention. We diagnosed primary colon cancer and subsequently performed extended left hemicolectomy. Histological examination revealed poorly differentiated adenocarcinoma resembling the gastric tumor he had 9 years earlier. The patient refused postoperative adjuvant chemotherapy and remained alive with cancerous peritonitis and skin metastases as of 17 months later. Case 2: A 46-year-old woman with a history of total gastrectomy for gastric cancer 9 years earlier presented with constipation. She also had a history of Krukenberg tumor 3 years earlier. We diagnosed metastatic rectal cancer and subsequently performed low anterior resection and hysterectomy. Pathological examination revealed poorly differentiated tubular adenocarcinoma, resembling the gastric tumor. The patient remained alive without recurrence as of 17 months later. DISCUSSION We found 19 reported cases of patients with resection of colon metastases from gastric cancer. Median disease-free interval was 74 months. CONCLUSION Resection of late-onset colorectal recurrence from gastric cancer appears worthwhile for selected patients. PMID:25460445

    The objective of this study was to investigate the associations among lung cancer location, and epidermal growth factor receptor (EGFR) mutation status. Treatment-naive, pathologically confirmed lung adenocarcinomas with tumor specimens available for genetic analysis were included from 2011 through 2014. Overall, 1771 patients with lung adenocarcinoma were included for analysis, after excluding those with carcinoma not otherwise specified, or synchronous multiple primary lung cancers. The median age was 64 years, and the female:male and never smoker:ever smoker ratios were 930:855 (52:48%) and 1167:604 (65:35%), respectively. The EGFR mutation rate was 56%. Among patients, 1093 (62%) had primary tumors in the upper lobes. Compared with the characteristics of the EGFR wild-type, tumors with EGFR activating mutations were more common in women (P < 0.001), never smokers (P < 0.001), and in the upper lobes (P = 0.004). Among EGFR activating mutations, compared with the EGFR exon 19 deletion, L858R mutation were more common in women (P = 0.002), never smokers (P = 0.038), and the upper lobes P < 0.0005). The present study is the first to address that different pulmonary lobar locations might harbor different EGFR mutation subtypes. We demonstrated that adenocarcinomas with L858R mutation, rather than exon 19 deletion or wild-type EGFR gene, prefer to locate over the upper lungs. This phenomenon was more significant in females and never-smokers, implying the result of complex interactions between genetic susceptibility and environmental factors. Therefore, EGFR L858R mutation and exon 19 deletion may not be identical disease entity from the point of carcinogenesis.

    A total volume method of culturing dialysis fluid from continuous ambulatory peritoneal dialysis patients during episodes of peritonitis was developed. Concentrated culture media stored in small blood transfer bags were added directly to the drained dialysate exchange bags by the same technique used to carry out the dialysate exchange. The exchange bag with the added culture medium was incubated at 35 degrees C and observed for turbidity. Seventy-eight dialysis exchange bags from patients without clinical peritonitis (negative controls) and forty-eight dialysis exchange bags from patients with clinical peritonitis were cultured. Bacteria were recovered from all cultures of patients with clinical peritonitis (100% sensitivity) and from five cultures of negative control fluids (94% specificity). Of these isolates, 86% were gram positive, and 14% were gram negative. This technique represents an advance over previously described culture techniques in its ability to isolate the causative organism(s) in cases of peritonitis in continuous ambulatory peritoneal dialysis patients.

    Cancers are composed of populations of cells with distinct molecular and phenotypic features, a phenomenon termed intra-tumor heterogeneity (ITH). ITH in lung cancers has not been well studied. We applied multi-region whole exome sequencing (WES) on 11 localized lung adenocarcinomas. All tumors showed clear evidence of ITH. On average, 76% of all mutations and 20/21 known cancer gene mutations were identified in all regions of individual tumors suggesting single-region sequencing may be adequate to identify the majority of known cancer gene mutations in localized lung adenocarcinomas. With a median follow-up of 21 months post-surgery, 3 patients have relapsed and all 3 patients had significantly larger fractions of subclonal mutations in their primary tumors than patients without relapse. These data indicate larger subclonal mutation fraction may be associated with increased likelihood of postsurgical relapse in patients with localized lung adenocarcinomas. PMID:25301631

    A study was carried out to determine whether it was possible to classify colonic and ovarian adenocarcinomas by their antigen profile. Colonic and ovarian adenocarcinomas were immunostained with a panel of antibodies which have a limited specificity for colon (parlam-4, 19.9, anti-secretory component) and ovary (OV-TL3 and OC125) and the most discriminatory antibodies were selected by stepwise linear discriminant analysis. For frozen material OV-TL3 and OC125 were the best classifying antibodies. Although OC125 had better discriminative power, for paraffin wax embedded material parlam-4 was selected as the best classifying antibody. OC125 had no additional effect on the classification of a tumour. These antibodies were subsequently tested on an independent test set of primary and metastatic adenocarcinomas of colonic and ovarian origin. When ovarian posterior probabilities of less than 0.1 and greater than 0.9 were selected as cut off points for a positive identification of colonic or ovarian origin (jackknifed classification method), no adenocarcinoma was incorrectly identified as ovarian carcinoma in frozen material. The same trend was noticed for paraffin wax embedded material. Statistical analysis of antigen profiles can be helpful in defining the colonic or ovarian origin of an adenocarcinoma when routine microscopy does not yield a definitive result. PMID:3384998

    The development of APD technologies enables physician to customize PD treatment for optimal dialysis. Dialysis dose can be increased with APD alone or in conjunction with daytime dwells. Although there is no strong evidence of the advantage over CAPD, APD is generally recommended for patients having a high peritoneal transport, outflow problems or high intraperitoneal pressure (IPP) and those who depend on caregivers for their dialysis. The benefits of APD over CAPD depends on the problems and treatment results among dialysis centers. Before starting the APD, medical, psychosocial and financial aspects, catheter function, residual renal function (RRF), body surface area and peritoneal transport characteristic must be evaluated. The recommended starting prescription for APD is the dwell volume of 1,500 ml/m2, 2 hours/cycle, and 5 cycles/session, which will provides 10-15 L of total volume and 10 hours per session. The IPP should be monitored and kept below 18 cmH2O. NIPD is accepted for patients with significant RRF. Anuric patients usually require 15-20 L of total fill volume and may need 1-2 day-dwells of 2L icodextrin or hypertonic glucose solutions. Small solute clearances and ultrafiltration depend on the peritoneal catheter function and dialysis schedule. The clinical outcomes and small solute clearances must be monitored and adjusted accordingly to meet the weekly total Kt/V urea > or = 1.7 and in low peritoneal transporters, the weekly total CCr should be > or = 45 L/1.73 m2. The volume status must be normal. To diagnose the peritonitis in NIPD patients, 1 L of PDF should be infused and permitted to dwell for 2 hours before sending for analysis. The differential of white cell count may be more useful than the total cell counts. In Siriraj Hospital, APD patients had 1.5-3 times less peritonitis than CAPD patients and most of our anuric patients can achieve the weekly total Kt/V urea target with 10 L of NIPD.

    Background. Peritoneal Carcinomatosis Index (PCI) is a widely established scoring system that describes disease burden in isolated colorectal peritoneal carcinomatosis (CPC). Its significance may be diminished with complete cytoreduction. We explore the utility of the recently described Peritoneal Surface Disease Severity Score (PSDSS) and compare its prognostic value against PCI. Methods. The endpoints were overall survival (OS), progression-free survival (PFS), and survival less than 18 months (18 MS). Results. Fifty patients underwent cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) for CPC from 2003 to 2014, with 98% achieving complete cytoreduction. Median OS was 28.8 months (95% CI, 18.0–39.1); median PFS was 9.4 months (95% CI, 7.7–13.9). Univariate analysis showed that higher PCI was significantly associated with poorer OS (HR 1.11; 95% CI, 1.03–1.20) and PFS (HR 1.09; 95% CI, 1.03–1.14). Conversely, PSDSS was not associated with either endpoint. Multivariate analysis showed that PCI, but not PSDSS, was predictive of OS and PFS. PCI was also able to discriminate survival outcomes better than PSDSS for both OS and PFS. There was no association between 18 MS and either score. Conclusion. PCI is superior to PSDSS in predicting OS and PFS and remains the prognostic score of choice in CPC patients undergoing CRS/HIPEC. PMID:27006828

    Alpha-fetoprotein (AFP) producing gastric adenocarcinoma is considered as a rare subtype of gastric adenocarcinoma. Compared with AFP non-producing gastric adenocarcinoma, our study and other previous studies showed that AFP producing gastric adenocarcinoma is more aggressive and prone to liver metastasis. Using the Protein Pathway Array, 11 of out of 286 proteins tested were found to be differentially expressed between AFP producing (n=32) and AFP non-producing (n=45) gastric adenocarcinoma tissues. In addition, the high level expression of XIAP and IGF-Irβ in gastric adenocarcinoma tissues was independent factors for poor prognosis in AFP producing gastric adenocarcinoma patients. A risk model based on the XIAP and IGF-Irβ expression levels can separate AFP producing gastric adenocarcinoma patients into 2 subgroups and each subgroup had a distinct set of signaling pathways involved. In conclusion, AFP producing gastric adenocarcinoma is a heterogeneous cancer with different clinical outcomes, biological behaviors and underlying molecular alterations. PMID:27057629

    Introduction Spontaneous peritonitis, especially spontaneous fungal peritonitis (SFP), is an important and potentially fatal complication in patients with endstage liver disaese. We evaluated potential risk factors, microbiological findings, and outcome of patients with SFP compared to spontaneous bacterial peritonitis (SBP) in critically ill patients. Methods Retrospective analyses of critically ill patients with suspected spontaneous peritonitis. Results Out of 205 patients, 20 (10%) had SFP, 28 (14%) had SBP, 48 (24%) had peritonitis without microbiological findings (SP) and 109 (52%) had no-peritonitis (NP). APACHE II and SOFA score were significantly higher in patients with SFP (26; 22–28; p<0.004 and 16; 14–18; p<0.002), SBP (26; 22–28; p<0.004 and 16; 14–18; p<0.002) and SP (24; 18–30; p<0.045 and 14; 10–18; p<0.044) as compared to NP (22; 16–24 and 12; 10–14). CHILD Pugh classification was mainly CHILD C and MELD Score was in patients with SFP (34; 18–40; p<0.001), SBP (32;12–40 p<0.002) and SP (29; 14–40 p<0.003) significantly higher as compared to NP (25;8–40). Nosocomial peritonitis could be significantly more often found in patients with SFP (65%; p<0.023) and SBP (62%, p<0.030) as compared to SP (51 p = 0.243) and NP (45%). Antibiotic pretreatment last 3 month prior peritonitis was significantly more often in patients with SFP (85%; p<0.002), SBP (71%, p<0.033), and SP (56; p<0.040) as compared to NP (33%). Candida albicans (60%; 12/20) was the most common isolated fungus, followed by Candida glabrata (13%) and Candida krusei (13%). Mortality rate was significantly higher in patients with SFP (90%, p<0.001), followed by SBP (75%; p<0.001) and SP (69%; p<0.001) as compared to NP (45%). Conclusion SFP is not a rare complication in end stage liver disease which is associated with increased mortality. Physicians should be aware of SFP in patients with CHILD C liver cirrhosis, elevated MELD score, antibiotic pretreatment and

    Ovarian/primary peritoneal carcinoma and breast carcinoma are the gynaecological cancers that most frequently involve the serosal cavities.With the objective of improving on the limited diagnostic panel currently available for the differential diagnosis of these two malignancies,as well as to define tumour-specific biological targets, we compared their global gene expression patterns. Gene expression profiles of 10 serous ovarian/peritoneal and eight ductal breast carcinoma effusions were analysed using the HumanRef-8 BeadChip from Illumina.Differentially expressed candidate genes were validated using quantitative real-time PCR and immunohistochemistry. Unsupervised hierarchical clustering using all 54,675 genes in the array separated ovarian from breast carcinoma samples. We identified 288 unique probes that were significantly differentially expressed in the two cancers by greater than 3.5-fold, of which 81 and 207 were overexpressed in breast and ovarian/peritoneal carcinoma, respectively. SAM analysis identified 1078 differentially expressed probes with false discovery rate less than 0.05. Genes overexpressed in breast carcinoma included TFF1, TFF3, FOXA1, CA12, GATA3, SDC1, PITX1, TH, EHFD1, EFEMP1, TOB1 and KLF2. Genes overexpressed in ovarian/peritoneal carcinoma included SPON1, RBP1, MFGE8, TM4SF12, MMP7, KLK5/6/7, FOLR1/3,PAX8, APOL2 and NRCAM. The differential expression of 14 genes was validated by quantitative real-time PCR, and differences in 5 gene products were confirmed by immunohistochemistry. Expression profiling distinguishes ovarian/peritoneal carcinoma from breast carcinoma and identifies genes that are differentially expressed in these two tumour types. The molecular signatures unique to these cancers may facilitate their differential diagnosis and may provide a molecular basis for therapeutic target discovery.

    An evaluation of the characteristics of peritoneal solute and water transport is essential to assess the suitability of prescribing dialysis in patients suffering from chronic renal disease. There are currently a series of models to perform this evaluation. The peritoneal equilibration test (PET) evaluates the peritoneal transport capacity, classifying the patients into four transport categories: high, high-average, low-average, and low. The short PET enables the same evaluation to be made in only 2hours, and has been validated in paediatric patients. On the other hand, the MiniPET provides additional information by evaluating the free water transport capacity by the ultra-small pores, and the Accelerated Peritoneal Examination Time (APEX) evaluates the time when the glucose and urea equilibration curves cross, and has been proposed as the optimum dwell time to achieve adequate ultrafiltration. An analysis is presented on the current information on these diagnostic methods as regards free water transport via aquaporins, which could be an important tool in optimising solute and water transport in patients on chronic peritoneal dialysis, particularly as regards the cardiovascular prognosis.

    The predominance of coagulase-negative staphylococci as normal skin flora is thought to be a factor in their association with episodes of peritonitis in patients undergoing continuous ambulatory peritoneal dialysis. We investigated the prevalence of peritonitis-associated strains on the skin of 28 patients undergoing peritoneal dialysis. Coagulase-negative staphylococci were the most frequently isolated organisms, comprising 47% of peritoneal dialysis fluid isolates and 59% of body site isolates. A total of 142 coagulase-negative staphylococci were speciated, tested for their antimicrobial sensitivity and slime production, and identified by phage typing and plasmid-profile analysis. Staphylococcus epidermidis was the most commonly identified species from both peritoneal dialysis fluid (73%) and body sites (53%). Multiple antibiotic resistance was common, and the greater proportion of isolates were resistant to methicillin; 63.6% of peritoneal dialysis fluid isolates and 61.7% of body-site isolates. S. haemolyticus isolates were significantly more resistant to methicillin than other species. By phage typing and plasmid-profile analysis it was shown that peritonitis was rarely caused by skin-colonizing strains. In only 3 of 14 patients were peritonitis-associated strains isolated as skin colonizers, and no patients developed peritonitis due to organisms previously isolated as skin colonizers.

    Peritoneal carcinomatosis accompanied by malignant ascites is a major cause of death of advanced gastric cancer (GC). To comprehensively characterize the underlying genomic events involved in GC peritoneal carcinomatosis, we analyzed whole-exome sequences of normal gastric tissues, primary tumors, and malignant ascites from eight GC patients. We identified a unique mutational signature biased toward C-to-A substitutions in malignant ascites. In contrast, the patients who received treatment of adjuvant chemotherapy showed a high rate of C-to-T substitutions along with hypermutation in malignant ascites. Comparative analysis revealed several candidate mutations for GC peritoneal carcinomatosis: recurrent mutations in COL4A6, INTS2, and PTPN13; mutations in druggable genes including TEP1, PRKCD, BRAF, ERBB4, PIK3CA, HDAC9, FYN, FASN, BIRC2, FLT3, ROCK1, CD22, and PIK3C2B; and mutations in metastasis-associated genes including TNFSF12, L1CAM, DIAPH3, ROCK1, TGFBR1, MYO9B, NR4A1, and RHOA. Notably, gene ontology analysis revealed the significant enrichment of mutations in the Rho-ROCK signaling pathway-associated biological processes in malignant ascites. At least four of the eight patients acquired somatic mutations in the Rho-ROCK pathway components, suggesting the possible relevance of this pathway to GC peritoneal carcinomatosis. These results provide a genome-wide molecular understanding of GC peritoneal carcinomatosis and its clinical implications, thereby facilitating the development of effective therapeutics.

    An episode of fungal peritonitis was produced by Bipolaris spicifera in a 3-year-old girl with chronic renal failure secondary to uremic-hemolytic syndrome and who was under treatment with continuous ambulatory peritoneal dialysis (CAPD). Previously, an episode of purulent peritonitis caused by Pseudomonas spp. had been treated successfully with combined antibacterial therapy for 10 days. Microscopic and macroscopic examinations of the freshly collected purulent dialysate were negative for fungal structures and bacteria. The fungus grew from the dialysate plated on Sabouraud dextrose agar and was also macroscopically recognized as a colony attached to the inner wall of the Tenckhoff catheter. Specific cultures of dialysate for common bacteria and mycobacteria were negative. The patient was successfully treated with early catheter removal and empirical administration of 200 mg/day oral fluconazole for 2 weeks. Subsequently, a new catheter was placed and the patient continued well on CAPD. Post-treatment control cultures of dialysate for fungi, bacteria and mycobacteria were negative and the cell count returned to normal.

    Although highly successful as transcutaneous access devices, today's peritoneal dialysis catheters still have imperfect hydraulic function, biocompatibility and resistance to infection. Success of Tenckhoff catheters is greatly improved by the proper positioning of deep and subcutaneous cuffs and intraperitoneal segment. Newer peritoneal catheter designs are intended to improve hydraulic function, avoid outflow failure, and diminish exit site infection. These catheter designs serve as excellent alternatives for patients with various types of failure of Tenckhoff catheters. Catheters have been designed for Continuous Flow Peritoneal Dialysis, and have generally been successful in providing high peritoneal dialysis flow rate, but not always successful in optimally distributing flow of peritoneal fluid. Improvements in catheter design may expand the use of peritoneal dialysis as a successful home dialysis therapy. PMID:16485243

    PubMed

    Hemoperitoneum in peritoneal dialysis patients is a known but infrequent complication. Hemoperitoneum is more frequent in women because of its association with a variety of gynecologic presentations such as reflux menstruation, ovulation, endometrial tissue implants within the peritoneal cavity (endometriosis), and bleeding follicular cysts. Other intraperitoneal causes of hemoperitoneum include minor catheter or abdominal trauma, vascular anomalies, or hepatic or splenic cysts. Less frequently encountered is a presentation of hemoperitoneum from a retroperitoneal source. These presentations result either from peritoneal inflammation and subsequent peritoneal bleeding or retroperitoneal cavity pathology rupturing into the peritoneal cavity. Here, we present the case of a peritoneal dialysis patient presenting with hemoperitoneum several days after undergoing cardiac catheterization. The catheterization was complicated by a large retroperitoneal hematoma. Details of the case are reported, and other retroperitoneal causes of hemoperitoneum are reviewed.

    Methods have been developed to distinguish subpopulations of murine peritoneal cells, and these were applied to the measurement of early changes in peritoneal cells after irradiation. The ratio of the two major subpopulations in the peritoneal fluid, lymphocytes and macrophages, was measured rapidly by means of cell volume distribution analysis as well as by hypotonic propidium iodide (PI) staining. After irradiation, dose and time dependent changes were noted in the cell volume distributions: a rapid loss of peritoneal lymphocytes, and an increase in the mean cell volume of macrophages. The hypotonic PI staining characteristics of the peritoneal cells showed two or three distinctive G/sub 1/ peaks. The ratio of the areas of these peaks was also found to be dependent of the radiation dose and the time after irradiation. These results demonstrate that these two parameters may be used to monitor changes induced by irradiation (biological dosimetry), and to sort different peritoneal subpopulations.

    The subperitoneal space and peritoneal cavity are two mutually exclusive spaces that are separated by the peritoneum. Each is a single continuous space with interconnected regions. Disease can spread either within the subperitoneal space or within the peritoneal cavity to distant sites in the abdomen and pelvis via these interconnecting pathways. Disease can also cross the peritoneum to spread from the subperitoneal space to the peritoneal cavity or vice versa.

    Background Cardiorenal syndrome type 2 (CRS-2) is common in end-stage chronic heart failure (CHF). Peritoneal ultrafiltration (pUF) may entail clinical functional improvement and a reduction in hospitalizations. Methods Thirty-nine consecutive end-stage CHF patients with stable CRS-2 were initiated on ambulatory pUF after interdisciplinary cardiological/nephrological evaluation and prospectively followed for 1 year. All-cause hospitalization was the primary end point. Secondary end points included mortality, treatment alteration and change in weight, NYHA functional class or quality of life (QoL). Outcomes were compared both within the pUF cohort (365 prior to initiation) and with 39 matched CHF patients receiving standard medical treatment. Results Compared with pretreatment, there was a trend to a reduction in 1-year hospitalization days in the pUF group (P = 0.07). One-year mortality was 33% in the pUF group and 23% in the matched control cohort. pUF was stopped in eight patients (18%) due to recurrent peritonitis (n = 3), insufficient ultrafiltration (n = 3) or cardiac recompensation (n = 1). Compared with standard medical treatment, pUF significantly improved volume overload (P < 0.05), NYHA functional class (P < 0.001) and mental health (P < 0.05). Moreover, hospitalization days for all causes as well as cardiovascular hospitalization days were significantly reduced during the interim periods in the pUF group (P < 0.05 and P < 0.001, respectively). Conclusions pUF is effective in improving the clinical condition of end-stage CHF patients suffering from CRS-2. Randomized controlled trials are needed to clarify the effects of pUF on hospitalization and mortality in these patients. PMID:25815181

    We report 2 cases of primary thymic adenocarcinoma with enteric differentiation. One carcinoma occurred in a 41-year-old man as a 7-cm-diameter cystic tumor and the other one in a 39-year-old woman as a 6-cm-diameter solid mass. Both tumors were located in the anterior mediastinum. Clinical staging did not reveal any extrathymic tumor. Histologically, the tumors were classified as adenocarcinoma, not otherwise specified, and a mucinous (colloid) carcinoma, respectively. Immunohistochemically, both tumors were positive for cytokeratin 20 (CK20), CDX2, and carcinoembryonic antigen, reflecting enteric differentiation. A review of the literature on 43 other cases of primary thymic adenocarcinomas suggested 11 further cases with enteric differentiation, as assessed by CK20 and/or CDX2 expression. We propose that thymic adenocarcinoma with enteric differentiation represents a novel subtype of thymic carcinoma. It is mostly of mucinous morphology and frequently associated with thymic cysts. The clinical outcome is variable. Recognition of primary thymic adenocarcinoma with enteric differentiation is helpful for the differentiation from metastatic disease, mainly from the gastrointestinal tract. PMID:25517960

A review of the literature on 43 other cases of primary thymic adenocarcinomas suggested 11 further cases with enteric differentiation, as assessed by CK20 and/or CDX2 expression. We propose that thymic adenocarcinoma with enteric differentiation represents a novel subtype of thymic carcinoma. It is mostly of mucinous morphology and frequently associated with thymic cysts. The clinical outcome is variable. Recognition of primary thymic adenocarcinoma with enteric differentiation is helpful for the differentiation from metastatic disease, mainly from the gastrointestinal tract.

    Introduction Encapsulating peritoneal sclerosis (EPS) is a rare but devastating complication of peritoneal dialysis (PD). Tamoxifen has been generally well-tolerated, even without randomized controlled trials. Case Presentation Herein, we report a case of a patient undergoing 12 years of PD who developed EPS and calciphylaxis simultaneously. We also provide a comprehensive discussion about the association between EPS and calciphylaxis. Moreover, although tamoxifen is used in EPS due to its inhibition of fibroblast-transforming growth factor beta (TGFβ) production, it may worsen the calciphylaxis due to a hypercoagulable state. Conclusions We suggest avoiding the use of tamoxifen for EPS in patients with superimposed calciphylaxis.

    Herein, we report a 39-year-old female patient presenting with gastric cancer and tuberculous peritonitis. The differential diagnosis between advanced gastric cancer with peritoneal carcinomatosis and early gastric cancer with peritoneal tuberculosis (TB), and the treatment of these two diseases, were challenging in this case. Physicians should have a high index of suspicion for peritoneal TB if the patient has a history of this disease, especially in areas with a high incidence of TB, such as South Korea. An early diagnosis is critical for patient management and prognosis. A surgical approach including tissue biopsy or laparoscopic exploration is recommended to confirm the diagnosis. PMID:27433397

    OBJECTIVES: To evaluate the clinical outcomes and identify the predictors of mortality in elderly patients undergoing peritoneal dialysis. METHODS: We conducted a retrospective study including all incident peritoneal dialysis cases in patients ≥65 years of age treated from 2001 to 2014. Demographic and clinical data on the initiation of peritoneal dialysis and the clinical events during the study period were collected. Infectious complications were recorded. Overall and technique survival rates were analyzed. RESULTS: Fifty-eight patients who began peritoneal dialysis during the study period were considered for analysis, and 50 of these patients were included in the final analysis. Peritoneal dialysis exchanges were performed by another person for 65% of the patients, whereas 79.9% of patients preferred to perform the peritoneal dialysis themselves. Peritonitis and catheter exit site/tunnel infection incidences were 20.4±16.3 and 24.6±17.4 patient-months, respectively. During the follow-up period, 40 patients were withdrawn from peritoneal dialysis. Causes of death included peritonitis and/or sepsis (50%) and cardiovascular events (30%). The mean patient survival time was 38.9±4.3 months, and the survival rates were 78.8%, 66.8%, 50.9% and 19.5% at 1, 2, 3 and 4 years after peritoneal dialysis initiation, respectively. Advanced age, the presence of additional diseases, increased episodes of peritonitis, the use of continuous ambulatory peritoneal dialysis, and low albumin levels and daily urine volumes (<100 ml) at the initiation of peritoneal dialysis were predictors of mortality. The mean technique survival duration was 61.7±5.2 months. The technique survival rates were 97.9%, 90.6%, 81.5% and 71% at 1, 2, 3 and 4 years, respectively. None of the factors analyzed were predictors of technique survival. CONCLUSIONS: Mortality was higher in elderly patients. Factors affecting mortality in elderly patients included advanced age, the presence of comorbid

    We determined the ability of Staphylococcus epidermidis, Staphylococcus aureus, and Escherichia coli to survive and grow in peritoneal dialysis fluids from patients undergoing chronic ambulatory peritoneal dialysis. Staphylococci did not survive in commercially available dialysis solutions but grew readily in peritoneal effluents obtained from patients after the dialysis dwell time. The number of CFU doubled 6 and 13 times in 24 h for S. epidermidis and S. aureus, respectively. E. coli grew well in both the pre- and postdialysis peritoneal fluid. Peritoneal macrophages as well as peripheral blood leukocytes inhibited bacterial growth in peritoneal dialysis fluid. However, 10(6) phagocytes per ml were minimally required to obtain a bacteriostatic effect. The addition of serum to peritoneal dialysis fluid increased the antibacterial activity of macrophages and blood leukocytes. The capacity of the aminoglycoside antibiotic tobramycin to reduce bacterial CFU in peritoneal dialysis fluid was only 10% of its bactericidal capacity in standard Mueller-Hinton brush. Peritoneal dialysis fluid had no effect on the antibacterial activity of imipenem. PMID:6386844

    Based on the importance of assessing the true extent of peritoneal disease, PeRitOneal MalIgnancy Stage Evaluation (PROMISE) internet application (www.e-promise.org) has been developed to facilitate tabulation and automatically calculate surgically validated peritoneal cancer index (PCI), and other surgically validated scores as Gilly score, simplified peritoneal cancer index (SPCI), Fagotti and Fagotti-modified scores. This application offers computer-assistance to produce simple, quick but precise and standardized pre, intra and postoperative reports of the extent of peritoneal metastases and may help specialized and non-specialized institutions in their current practice but also facilitate research and multicentre studies on peritoneal surface malignancies.

    A 6-year-old Girolando dairy cow was presented for evaluation of a large subcutaneous facial mass. Fine-needle aspirates of the mass contained many neoplastic cells with high nuclear:cytoplasmic ratios arranged in sheets and loosely cohesive clusters with streaming erythrocytes and neutrophils in the background. Neoplastic cells were 13-25 μm in diameter and were round to cuboidal with variably distinct borders. Based on the signalment, anatomic location, and cytologic findings, differential diagnoses included salivary adenocarcinoma, squamous cell carcinoma, and mucoepidermoid carcinoma. The cow was euthanized and a necropsy was performed. The primary neoplasm arose from the left parotid salivary gland and meastatic tumor was found in the regional lymph nodes and lung. Histologically, the tumor was composed of anastomosing and irregular solid islets surrounded by scant stroma. Cells were negative for periodic acid-Schiff (PAS), PAS-diastase, and Alcian blue pH 2.5 stains, used to detect mucin. On immunohistochemical analysis, neoplastic luminal salivary gland cells expressed cytokeratin, but not S100, α-smooth muscle actin, or vimentin. Peripheral cells of neoplastic islets were immunoreactive for p63. The final diagnosis was nonsecretory adenocarcinoma of the parotid salivary gland. PMID:22954300

    Patients requiring cardiopulmonary bypass for congenital heart surgery commonly exhibit impaired renal function and extravascular fluid retention. These conditions contribute to early postoperative fluid overload, which may result in significant morbidity and mortality. We examined the safety and efficacy of peritoneal dialysis in removing extravascular fluid from critically ill postcardiotomy patients. A retrospective case review from July of 1995 through April of 1996 was conducted. All patients undergoing peritoneal dialysis achieved a net negative fluid balance. Average urine output increased from 2.1 cc/kg/hr to 3.9 cc/kg/hr (P < 0.01) during the pre-peritoneal dialysis to post-peritoneal dialysis period, and the mean number of inotropic agents decreased from 2.2 to 1.7 (P < 0.05). Controlled comparison revealed that the peritoneal dialysis cohort more rapidly achieved a negative weight-adjusted fluid balance throughout the early postoperative course. The peritoneal dialysis group's illness severity decreased more rapidly within the 24-hour period after initiation of peritoneal dialysis than did that of the control cohort over the same period of time. No difference in postoperative morbidity or mortality existed between the study groups. Complications from the catheter placement were minimal, and no patient experienced peritonitis or metabolic or hemodynamic instability during peritoneal dialysis catheter placement, usage, or removal. Peritoneal dialysis is a safe and effective form of renal replacement therapy, even among critically ill pediatric postcardiotomy patients. Early postsurgical institution of peritoneal dialysis may hasten early postoperative recovery. We speculate that intraoperative catheter placement reduces the complication rate associated with this treatment modality. PMID:9456479

    Adenocarcinoma of the ethmoid sinus is a rare tumor which has been epidemiologically linked to woodworking in the furniture industry. It has a low propensity to metastasize and has not been previously reported to cause spinal cord compression. A symptomatic epidural spinal cord compression was confirmed on magnetic resonance imaging (MRI) scan in a former furniture worker with widely disseminated metastases. The clinical features of ethmoid sinus adenocarcinoma and neoplastic spinal cord compression, and the comparative value of MRI scanning in the neuroradiologic diagnosis of spinal cord compression are reviewed.

    Optimal fluid removal on peritoneal dialysis (PD) requires removal of water coupled with sodium, which is predominantly achieved via the small pores in the peritoneal membrane. On the other hand, free-water transport takes place through aquaporin-1 channels, but leads to sodium retention and over hydration. PD prescription can be adapted to promote small pore transport to achieve improved sodium and fluid management. Both adequate dwell volume and dwell time are required for small pore transport. The dwell volume determines the amount of "wetted" peritoneal membrane being increased in the supine position and optimized at dwell volumes of approximately 1400 ml/m(2). Diffusion across the recruited small pores is time-dependent, favored by a long dwell time, and driven by the transmembrane solute gradient. According to the 3-pore model of conventional PD, sodium removal primarily occurs via convection. The clinical application of these principles is essential for optimal performance of PD and has resulted in a new approach to the automated PD prescription: adapted automated PD. In adapted automated PD, sequential short- and longer-dwell exchanges, with small and large dwell volumes, respectively, are used. A crossover trial in adults and a pilot study in children suggests that sodium and fluid removal are increased by adapted automated PD, leading to improved blood pressure control when compared with conventional PD. These findings are not explained by the current 3-pore model of peritoneal permeability and require further prospective crossover studies in adults and children for validation.

    The dysfunction of the catheter in peritoneal dialysis (PD) is a frequent complication. However, perforation of organs are rare, particularly that of the urinary bladder. This requires an early diagnosis and prompt treatment of patients. We report here the case of a 38-year-old woman having end-stage renal disease due to autosomal-dominant polycystic kidney disease treated by PD since November 2000. Three years later, she was treated for Staphylococcal peritonitis. Four months later, she presented with a severe urge to urinate at the time of the fluid exchanges. The biochemical analysis of the fluid from the bladder showed that it was dialysis fluid. Injection of contrast through the catheter demonstrated the presence of a fistula between the bladder and the peritoneal cavity. She underwent cystoscopic closure of the fistulous tract and the PD catheter was removed. Subsequently, the patient was treated by hemodialysis. One month later, a second catheter was implanted surgically after confirming the closure of the fistula. Ten days later, she presented with pain at the catheter site and along the tunnel, which was found to be swollen along its track. The injection of contrast produced swelling of the subcutaneous tunnel but without extravasation of the dye. PD was withdrawn and the patient was put back on hemodialysis. Bladder fistula is a rare complication in PD and diagnosis should be suspected when patient complains of an urge to pass urine during the exchanges, which can be confirmed by contrast study showing presence of dye in the bladder. PD may be possible after the closure of the fistula, but recurrence may occur. PMID:22569443

  5. Peritoneal dialysis: from bench to bedside

    2013-01-01

    Peritoneal dialysis was first employed in patients with acute renal failure in the 1940s and since the 1960s for those with end-stage renal disease. Its popularity increased enormously after the introduction of continuous ambulatory peritoneal dialysis in the end of 1970s. This stimulated both clinical and basic research. In an ideal situation, this should lead to cross-fertilization between the two. The present review describes two examples of interactions: one where it worked out very well and another where basic science missed the link with clinical findings. Those on fluid transport are examples of how old physiological findings on absorption of saline and glucose solutions were adopted in peritoneal dialysis by the use of glucose as an osmotic agent. The mechanism behind this in patients was first solved mathematically by the assumption of ultrasmall intracellular pores allowing water transport only. At the same time, basic science discovered the water channel aquaporin-1 (AQP-1), and a few years later, studies in transgenic mice confirmed that AQP-1 was the ultrasmall pore. In clinical medicine, this led to its assessment in patients and the notion of its impairment. Drugs for treatment have been developed. Research on biocompatibility is not a success story. Basic science has focussed on dialysis solutions with a low pH and lactate, and effects of glucose degradation products, although the first is irrelevant in patients and effects of continuous exposure to high glucose concentrations were largely neglected. Industry believed the bench more than the bedside, resulting in ‘biocompatible’ dialysis solutions. These solutions have some beneficial effects, but are evidently not the final answer.

    VAP-1 (vascular adhesion protein-1) possesses semicarbazide-sensitive amine oxidase (SSAO) activity. It has also been found that serum VAP-1 was elevated in acute and chronic hyperglycemia and in patients with diabetes as well as in chronic kidney disease. Renalase, with possible monoamine oxidase activity, which breaks down catecholamines such as SSAO, is expressed in the endothelium as well as in the kidney. The aim of the study was to assess serum VAP-1 levels in peritoneally dialyzed (PD) patients and factors explaining its variability. This pilot study was performed on 25 peritoneally dialyzed patients, including 4 patients with type 2 diabetes. We found that the mean VAP-1 was significantly higher in chronic ambulatory peritoneal dialysis (CAPD) patients when compared to the control group (p<0.05). Dopamine was significantly lower in PD patients when compared to the healthy volunteers (p<0.05), whereas noradrenaline was significantly higher in PD patients relative to the healthy volunteers (p<0.01). There was a significant difference in the VAP-1 concentration in the group with and without residual renal function (p<0.05) as well as between 10 patients with hyperglycemia when compared to patients with normoglycemia (p<0.05). There was no effect of gender on the serum VAP-1 levels. In PD patients VAP-1 correlated with systolic blood pressure (r=-0.4, p<005), residual renal function (r=-0.62, p<0.05), and glucose (=0.54, p<0.05). We concluded that VAP-1, elevated in patients on PD, was predominantly dependent on residual kidney function and glucose level, factors both linked to endothelial damage and cardiovascular complications.

    A case of Berardinelli-Seip syndrome, a congenital generalised lipodystrophy, is reported. Symptoms first appeared when the patient was 20 years old. She showed severe insulin resistance as well as micro- and macro-angiopathic complications, including chronic kidney disease, which required renal replacement therapy with peritoneal dialysis. The patient's clinical course was reviewed since paediatric age (when initial signs of the disease being already evident) to present time. Berardinelli-Seip syndrome is very uncommon, and the present case is particularly rare because it is the only case (at least as reported in the literature) in a patient receiving dialysis.

    Increased expression of the human DEK proto-oncogene (DEK) gene has been associated with numerous human malignancies. The DEK protein is associated with chromatin reconstruction and gene transcription, and is important in cell apoptosis. The present study aimed to elucidate the role of DEK with regard to gastric adenocarcinoma tumor progression and patient prognosis. DEK protein expression was analyzed using immunohistochemistry in 192 tumors paired with adjacent non-cancerous gastric mucosa that had been surgically resected from patients with primary gastric adenocarcinoma. The association between DEK expression and the clinicopathological characteristics of the patients was evaluated using the χ2 test and Fisher's exact test. The survival rates of the patients were calculated using the Kaplan-Meier method. Cox analysis evaluated the association between the expression of DEK and the survival rate of the patients. The DEK protein was expressed in 84 patients with gastric adenocarcinoma (43.8%) and in 20 of the paired normal gastric mucosa tissues (11.5%). The DEK expression rate was found to be associated with tumor size (P=0.006), tumor grade (P=0.023), lymph node metastasis (P=0.018), serous invasion (P=0.026), tumor stage (P=0.001) and Ki-67 expression (P=0.003). Furthermore, patients with gastric adenocarcinoma that expressed DEK had decreased disease-free (log-rank, 16.785; P<0.0001) and overall (log-rank, 15.759; P<0.0001) survival rates compared with patients without DEK expression. Patients with late-stage gastric adenocarcinoma that expressed DEK exhibited a lower overall survival rate compared with patients without DEK expression (P=0.002). Additional analysis revealed that DEK expression was an independent prognostic factor for the prognosis of gastric adenocarcinoma (hazard ratio, 0.556; 95% confidence interval, 0.337–0.918; P=0.022). From the results of the present study, it can be concluded that the detection of DEK protein expression in gastric

    The present study aimed to investigate the expression levels of tumor necrosis factor-α-induced protein 8 (TNFAIP8) in gastric adenocarcinoma. TNFAIP8 expression levels in gastric adenocarcinoma tissue samples (with and without lymph node metastasis), adjacent normal tissue samples and metastatic lymph node tissue samples were detected by immunohistochemistry. The correlation between TNFAIP8 expression levels and clinicopathological data and gastric adenocarcinoma prognosis was analyzed. The results demonstrated that TNFAIP8 expression in gastric adenocarcinoma tissue samples and metastatic lymph node tissue samples markedly increased at a rate of 47.2% (50/106) and 81.7% (49/60), respectively, as compared with the adjacent normal tissue samples in which no TNGFAIP8 expression was detected (0%). This increase in TNFAIP8 expression was statistically significant. TNFAIP8 expression rates in the primary tumors (60%, 36/60) of patients with lymph node metastasis were significantly higher compared with the primary tumors of patients without lymph node metastasis (30.4%, 14/46). TNFAIP8 expression was associated with an increase in the severity of TNM stage, tumor grade, vascular invasion, lymph node metastasis and serum CA72-4 levels. The overall survival rate of patients with gastric adenocarcinoma and high TNFAIP8 expression was poorer compared with patients with low TNFAIP8 expression, and TNFAIP8 expression was negatively correlated with patient prognosis. The results also demonstrated that TNFAIP8 was an independent prognostic marker in gastric adenocarcinoma (relative risk, 1.736; P=0.029). In conclusion, the results of the present study demonstrated that TNFAIP8 expression was associated with the occurrence, development and metastasis of gastric adenocarcinoma, and negatively correlated with the prognosis of patients with gastric adenocarcinoma. TNFAIP8 may therefore serve as a prognostic factor for gastric adenocarcinoma. PMID:27347043

    The role of thyroid transcription factor 1 (TTF-1) in the diagnosis of metastatic pulmonary adenocarcinomas in pleural, pericardial, and peritoneal effusions has not been defined. This study aimed to assess the overall diagnostic accuracy of TTF-1 for metastatic pulmonary adenocarcinomas in pleural or other effusions. Literature search was conducted in PubMed, EMBASE, and other databases to find eligible publications. Quality was assessed according to standardized QUADAS-2 criteria. Sensitivity, specificity, positive/negative likelihood ratio (PLR/NLR), and diagnostic odds ratio (DOR) were pooled. Summary receiver operating characteristic (SROC) curves were used to assess overall performance of the TTF-1 assay. A systematic search revealed 20 studies comprising a total of 1,213 subjects in this meta-analysis. The summary estimates were listed as follows: sensitivity, 0.74 (95% CI: 0.69–0.79); specificity, 0.99 (95% CI: 0.97–1.00); PLR, 78.16 (95% CI: 27.15–225.05); NLR, 0.26 (95% CI: 0.22–0.32); and diagnostic odds ratio, 297.75 (95% CI: 104.16–851.19). Estimated positive and negative post-probability values for metastatic pulmonary adenocarcinomas prevalence of 20% were 95% and 6%, respectively. The area under the SROC curve was 0.96. TTF-1 shows significant potential as a diagnostic marker to differentiate metastatic pulmonary from non-pulmonary adenocarcinomas in pleural or other effusions. These results justify larger, more rigorous studies to confirm such a diagnostic role. PMID:26806377

    Mesothelial-to-mesenchymal transition (MMT) is an autoregulated physiological process of tissue repair that in uncontrolled conditions, such as peritoneal dialysis (PD), can lead to peritoneal fibrosis. The maximum expression of sclerotic peritoneal syndromes (SPS) is the encapsulating peritoneal sclerosis (EPS) for which no specific treatment exists. The SPS includes a wide range of peritoneal fibrosis that appears progressively and is considered as a reversible process, while EPS does not. EPS is a serious complication of PD characterized by a progressive intra-abdominal inflammatory process that results in bridles and severe fibrous tissue formation which cover and constrict the viscera. Recent studies show that transdifferentiated mesothelial cells isolated from the PD effluent correlate very well with the clinical events such as the number of hemoperitoneum and peritonitis, as well as with PD function (lower ultrafiltration and high Cr-MTC). In addition, in peritoneal biopsies from PD patients, the MMT correlates very well with anatomical changes (fibrosis and angiogenesis). However, the pathway to reach EPS from SPS has not been fully and completely established. Herein, we present important evidence pointing to the MMT that is present in the initial peritoneal fibrosis stages and it is perpetual over time, with at least theoretical possibility that MMT initiated the fibrosing process to reach EPS.

    An adult female hyacinth macaw (Anodorhynchus hyacinthinus) was presented for sudden onset of severe weakness in the legs. Neurologic examination revealed bilateral paresis of the pelvic limbs and decreased proprioception. Results of radiographs and computed tomography (CT) revealed variably sized soft tissue nodules throughout the lungs and invading into the spine and vertebral canal. Soon after the CT scan, the bird went into cardiorespiratory arrest and died. At necropsy, several yellow, coalescing nodules that were firm with a caseous component were present in the lungs, and a focus of similar tissue was attached to the vertebrae and invaded the spinal canal. On histologic examination, the diagnosis was primary pulmonary bronchial adenocarcinoma with spinal invasion.

    An 82-year-old man presented with progressive right frontal headaches. The patient's history was significant for benign polyps on surveillance colonoscopy 2 years prior, without high-grade dysplasia or carcinoma. MRI revealed an enhancing lesion arising within the superomedial aspect of the right orbit. Lesion biopsy demonstrated histological appearance and immunophenotype suggestive of colonic adenocarcinoma. Staging positron emission tomography/CT showed visceral metastases and diffuse activity in the posterior rectosigmoid, consistent with metastatic colon cancer. Treatment of the orbital lesion with external beam radiotherapy to 30 Gy resulted in significant palliation of the patient's headaches. The patient expired 2 months following treatment completion due to disease progression. Orbital metastasis as the initial presentation of an occult colorectal primary lesion is exceedingly rare, and occurred in this patient despite surveillance colonoscopy. Radiotherapy remains an efficacious modality for treatment of orbital metastases. PMID:25240005

    In peritoneal dialysis (PD), a well-functioning catheter is of great importance, because a dysfunctional catheter may be associated with incidence of peritonitis, efficiency of dialysis, and to the overall quality of treatment, representing one of the main barriers to optimal use of PD. When considering the relationship between PD catheter type and outcomes, we should keep in mind the different types of available PD catheters, those that are most commonly used in clinical practice, and the available head-to-head comparisons in the literature. The main differences in PD catheter design include the number of cuffs, the shape of subcutaneous tract (straight vs. swan neck), and the shape of intraperitoneal tract (straight vs. coiled). The availability of the best catheter design and materials, along with a skillful management of PD access, may have the greatest impact on long-term patient outcome on PD. It is now established that the use of straight catheters may improve outcomes and technique survival, but further advances in PD catheter technology can potentially improve technique survival. The self-locating PD catheter is a well established device that has not been fully studied and it may represent, based on the available observational evidence and on the clinical experience, an already existing technological advance deserving further studies.

  4. Possible development of idiopathic sclerosing encapsulating peritonitis.

    We report a rare case of idiopathic sclerosing encapsulating peritonitis (SEP). During a laparotomy before undergoing a distal gastrectomy with Billroth II reconstruction for early gastric cancer, the patient was found to have a membranous encapsulation wrapping each small bowel loop, unlike peritoneal encapsulation or typical SEP. He had complained of persistent heartburn, distension and diarrhea for 2 months in the post-operative course. The second laparotomy, which was performed to improve prolonged transit, revealed typical SEP with a thick and fibrotic membrane that encased the small bowel entirely. Stripping of the sclerosing encasing membrane, separation of the adherent loops of the proximal small bowel, and Braun's anastomosis were performed. The patient complained of epigastric fullness and diarrhea after he was relieved from the complete bowel obstruction for 45 days post-operatively. Trimebutine maleate was administrated 5 months after the second operation and this markedly improved his symptoms. This case might reflect the developmental process of idiopathic SEP. In addition, the use of a motility regulator may improve symptoms related to the abnormal intestinal motility by this disease. PMID:10228820

    Fluorescence-guided diagnostics is one of the most promising approaches for facile detection of cancer in situ. Here we focus on β-galactosidase, which is overexpressed in primary ovarian cancers, as a molecular target for visualizing peritoneal metastases from ovarian cancers. As existing fluorescence probes are unsuitable, we have designed membrane-permeable HMRef-βGal, in which the optimized intramolecular spirocyclic function affords >1,400-fold fluorescence enhancement on activation. We confirm that HMRef-βGal sensitively detects intracellular β-galactosidase activity in several ovarian cancer lines. In vivo, this probe visualizes metastases as small as <1 mm in diameter in seven mouse models of disseminated human peritoneal ovarian cancer (SHIN3, SKOV3, OVK18, OVCAR3, OVCAR4, OVCAR5 and OVCAR8). Because of its high brightness, real-time detection of metastases with the naked eye is possible. Endoscopic fluorescence detection of metastases is also demonstrated. The results clearly indicate preclinical potential value of the probe for fluorescence-guided diagnosis of peritoneal metastases from ovarian cancers.

    Rabbit IgG and its Fab, Fc and pFc' fragments, prepared by papain or peptic digestion, were assayed for binding to homologous peritoneal macrophages. The binding affinity of IgG for the peritoneal macrophages (Ka = 5.9 +/- 1.6 x 10(5) L/M) was comparable to that recorded with alveolar macrophages (7.6 +/- 1.8 x 10(5) L/M, Arend & Mannik, 1973) but the number of receptor sites per peritoneal cell (4.6 +/- 2.1 x10(6)) was about four-fold greater than on the latter. Of the fragments, only Fc bound to macrophages with an affinity comparable to intact IgG; pFc' bound weakly and Fab was totally inactive. These data, taken with a recent study involving rabbit IgG and guinea-pig macrophages (Ovary, Saluk, Quijada & Lamm, 1976), indicate that the primary IgG binding site for macrophages is located in the C gamma 2 domain.

  7. Laparoscopic versus open peritoneal dialysis catheter insertion, the LOCI-trial: a study protocol

    PubMed Central

    2011-01-01

    Background Peritoneal dialysis (PD) is an effective treatment for end-stage renal disease. It allows patients more freedom to perform daily activities compared to haemodialysis. Key to successful PD is the presence of a well-functioning dialysis catheter. Several complications, such as in- and outflow obstruction, peritonitis, exit-site infections, leakage and migration, can lead to catheter removal and loss of peritoneal access. Currently, different surgical techniques are in practice for PD-catheter placement. The type of insertion technique used may greatly influence the occurrence of complications. In the literature, up to 35% catheter failure has been described when using the open technique and only 13% for the laparoscopic technique. However, a well-designed randomized controlled trial is lacking. Methods/Design The LOCI-trial is a multi-center randomized controlled, single-blind trial (pilot). The study compares the laparoscopic with the open technique for PD catheter insertion. The primary objective is to determine the optimum placement technique in order to minimize the incidence of catheter malfunction at 6 weeks postoperatively. Secondary objectives are to determine the best approach to optimize catheter function and to study the quality of life at 6 months postoperatively comparing the two operative techniques. Discussion This study will generate evidence on any benefits of laparoscopic versus open PD catheter insertion. Trial registration Dutch Trial Register NTR2878 PMID:22185091

    Primary adenocarcinoma of the small intestine occurs in over 50% of cases in the duodenum. However, its location in the third and fourth duodenal portions occurs rarely and is a diagnostic challenge. The aim of this work is to report an adenocarcinoma of the third and fourth duodenal portions, emphasizing its diagnostic difficulty and the value of video capsule endoscopy. A man, 40 years old, with no medical history, with abdominal discomfort and progressive fatigue, presented four months ago with one episode of moderate melena. The physical examination was normal, except for mucosal pallor. Blood tests were consistent with microcytic, hypochromic iron deficiency anemia with 7.8 g/dL hemoglobin. The upper and lower endoscopy were normal. Additional work-up with video capsule endoscopy showed a polypoid lesion involving the third and fourth portions of the duodenum. Biopsy showed a moderately differentiated adenocarcinoma. Abdominal computed tomography showed a wall thickening from the third duodenal portion to the proximal jejunum, without distant metastasis. The patient underwent segmental resection (distal duodenum and proximal jejunum) with duodenojejunostomy. The surgical specimen histology confirmed the biopsy diagnosis, with transmural infiltration, without nodal involvement. Conclusion: Adenocarcinoma of the third and fourth portions of the duodenum is difficult to diagnose and capsule endoscopy is of great value. PMID:26309371

    Long-term outcome data in pancreatic adenocarcinoma are predominantly based on surgical series, as resection is currently considered essential for long-term survival. In contrast, five-year survival in non-resected patients has rarely been reported. In this report, we examined the incidence and natural history of ≥ 5-year survivors with non-resected pancreatic adenocarcinoma. All patients with pancreatic adenocarcinoma who received oncologic therapy alone without surgery at our institution between 1995 and 2009 were identified. Non-resected ≥ 5-year survivors represented 2% (11/544) of all non-resected patients undergoing treatment for pancreatic adenocarcinoma, and 11% (11/98) of ≥ 5-year survivors. Nine patients had localized tumor and 2 metastatic disease at initial diagnosis. Disease progression occurred in 6 patients, and the local tumor bed was the most common site of progression. Six patients suffered from significant morbidities including recurrent cholangitis, second malignancy, malnutrition and bowel perforation. A rare subset of patients with pancreatic cancer achieve long-term survival without resection. Despite prolonged survival, morbidities unrelated to the primary cancer were frequently encountered and a close follow-up is warranted in these patients. Factors such as tumor biology and host immunity may play a key role in disease progression and survival.

    Urachal adenocarcinoma is a rare and aggressive form of bladder cancer that arises from the urachus. An en bloc resection of the urachus and umbilicus is recommended with either a total or partial cystectomy. However, there is no standard laparoscopic or robotic surgical technique for the operative management of these tumors. In the present report, we describe our robotic-assisted laparoscopic technique for the treatment of a primary malignant urachal tumor. PMID:26531120

    Abdominal pain is a frequent complaint in the pediatric emergency department. A 13-year-old boy presented with complaints of abdominal pain, hematemesis, headache, and leg pain. Further investigation revealed an advanced-stage gastric adenocarcinoma with multiple thromboembolism including the greater saphenous vein and nonbacterial thrombotic endocarditis. This case points out the challenges of diagnosing this rare condition and treating the primary tumor and thromboembolism in the setting of both hypercoagulable state and gastrointestinal bleeding.

    The aim of the study was to assess pH, pO2 and pCO2 in peritoneal fluid. The study was conducted on a group of 22 dogs with symptoms of ascites. Group 1 consisted of 4 dogs with adenocarcinoma, group 2--of 6 dogs with glomerulonephritis, group 3 of 8 dogs with hepatic cirrhosis and group 4 of 4 dogs with bacterial peritonitis. An abdominal cavity puncture was performed in all dogs and the fluid was drawn into a heparinized syringe in order to assess pH, pO2 and pCO2 . The analysis of pH in the peritoneal fluid revealed statistically significant differences between group 4 and groups 1 (p=0.01), 2 (p=0.01), and 3 (p=0.01). The lowest pH value compared to the other studied groups was recorded in group 4. In group 4, the pO2 was the lowest compared to the other groups (group 1 p=0.01, group 2 p=0.01, group 3 p=0.01). The value of pCO2 was the highest in group 4 compared to groups 1, 2, and 3. The study found statistically significant differences in pH, pCO2 and pCO2 between group 4 (the group of dogs with bacterial peritonitis) and the other groups of dogs. This was probably linked to the pathogenesis of peritonitis. As a result of an inflammatory reaction within the peritoneal cavity, there is an increase in fibrin accumulations leading to a decreased oxygen supply causing the oxidative glucose metabolism to change into a non-oxidative glucose metabolism. This, in turn, causes a decrease in pH, acidosis, and a low oxidoreduction potential. It also impairs phagocytosis and activates proteolytic enzymes which create ideal conditions for the growth of anaerobic bacteria. The obtained results indicate that the pH, pO2 and pCO2 may be used to differentiate bacterial peritonitis from ascites of other etiologies.

    MicroRNAs have potential as diagnostic cancer biomarkers. The aim of this study was (1) to define microRNA expression patterns in formalin-fixed parafin-embedded tissue from pancreatic ductal adenocarcinoma, ampullary adenocarcinoma, normal pancreas and chronic pancreatitis without using micro-dissection and (2) to discover new diagnostic microRNAs and combinations of microRNAs in cancer tissue. The expression of 664 microRNAs in tissue from 170 pancreatic adenocarcinomas and 107 ampullary adenocarcinomas were analyzed using a commercial microRNA assay. Results were compared with chronic pancreatitis, normal pancreas and duodenal adenocarcinoma. In all, 43 microRNAs had higher and 41 microRNAs reduced expression in pancreatic cancer compared with normal pancreas. In all, 32 microRNAs were differently expressed in pancreatic adenocarcinoma compared with chronic pancreatitis (17 higher; 15 reduced). Several of these microRNAs have not before been related to diagnosis of pancreatic cancer (eg, miR-492, miR-614, miR-622). MiR-614, miR-492, miR-622, miR-135b and miR-196 were most differently expressed. MicroRNA profiles of pancreatic and ampullary adenocarcinomas were correlated (0.990). MicroRNA expression profiles for pancreatic cancer described in the literature were consistent with our findings, and the microRNA profile for pancreatic adenocarcinoma (miR-196b-miR-217) was validated. We identified a more significant expression profile, the difference between miR-411 and miR-198 (P=2.06 × 10(-54)) and a diagnostic LASSO classifier using 19 microRNAs (sensitivity 98.5%; positive predictive value 97.8%; accuracy 97.0%). We also identified microRNA profiles to subclassify ampullary adenocarcinomas into pancreatobiliary or intestinal type. In conclusion, we found that combinations of two microRNAs could roughly separate neoplastic from non-neoplastic samples. A diagnostic 19 microRNA classifier was constructed which without micro-dissection could discriminate pancreatic

    A 10-year-old, intact female Yorkshire terrier had multiple pulmonary nodules on thoracic radiography and ultrasonography with no lesions elsewhere. Computed tomography (CT) and positron emission tomography and computed tomography (PET-CT) using 18F-fluorodeoxyglucose (FDG) were performed to identify metastasis and undetected primary tumors. On CT examination, pulmonary nodules had a hypoattenuating center with thin peripheral enhancement, suggesting ischemic or necrotizing lesion. In PET-CT at 47 min after intravenous injection of 11.1 MBq/kg of FDG, the maximum standardized uptake value of each pulmonary nodule was about from 3.8 to 6.4. There were no abnormal lesions except for four pulmonary nodules on the CT and PET-CT. Primary lung tumor was tentatively diagnosed, and palliative therapy using 2 mg/kg tramadol and 2.2 mg/kg carprofen twice per day was applied. After the dog's euthanasia due to deteriorated clinical signs and poor prognosis, undifferentiated pulmonary adenocarcinoma was diagnosed through histopathologic and immunochemistry examination. To the best of the authors' knowledge, this is the first study of CT and PET-CT features of canine pulmonary adenocarcinoma. In this case, multiple pulmonary adenocarcinoma could be determined on the basis of FDG PET-CT through screening the obvious distant metastasis and/or lymph node invasions and excluding unknown primary tumors.

    Worldwide, cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has been used for nearly 3 decades to treat peritoneal metastases (PM), improve quality of life, and prolong survival substantially in selected patients. In India, the use of the combined modality of treatment dates back a decade with majority of the efforts taking place within the last 5 years. The first PSOGI workshop (India) held in April 2015, at Bangalore, India offered an opportunity for Indian surgeons performing CRS and HIPEC to share their experience. To study the methodologies of CRS and HIPEC (hospital set up, equipment, training and surgical background) as well as the outcomes in terms of perioperative morbidity and mortality and short and long term survival of patients treated in India, Indian surgeons who had treated at least 10 patients with this combined modality were invited to present their experience. Data collection was retrospective. Analysis of the pooled data was carried out. Eight surgeons treated 384 patients with CRS and HIPEC over a period of 10 years. The commonest primary sites were ovary (as first line therapy n = 124), followed by appendix, including pseudomyxoma peritonei (n = 99), colorectum (n = 77), recurrent ovary (as second line therapy, n = 33), stomach (n = 15), primary peritoneal cancer (n = 10), peritoneal mesothelioma (n = 9) and rare tumors in 17 patients. The weighted mean PCI for all 384 patients was 18.25. 349/384 patients (90.88 %) had a complete cytoreduction (completeness of cytoreduction score of CC-0/1). Grade 3-5 complications developed in 108 patients (27.34 %) and 30 day mortality occurred in 28 (7.29 %) patients. This study showed that CRS and HIPEC can be performed with an acceptable morbidity and mortality in Indian patients. Most of the surgeons are on the learning curve and further improvement in these outcomes is expected over a period of time. Pooling of data related to both common and rare

    Postoperative peritonitis (POP) is a common surgical complication after bariatric surgery (BS). We assessed the importance of positive fungal cultures in these cases of POP admitted to the intensive care unit. Clinical features and outcome were compared in 25 (41%) Candida-positive patients (6 (22%) fluconazole-resistant Candida glabrata) and 36 patients without Candida infection. Candida infections were more commonly isolated in late-onset peritonitis and were often associated with multidrug-resistant bacteria. Risk factors for intensive care unit mortality (19.6%) were diabetes and superobesity. Candida infections, including fluconazole-resistant strains, are common in POP after BS. These data encourage the empirical use of a broad-spectrum antifungal agent.

  18. [Adjuvant therapy of peritonitis with taurolidine. Modulation of mediator liberation].

    1997-01-01

    Despite aggressive surgical treatment, prompt antibiotic therapy, and modern intensive care, up to one half of patients still die of diffuse peritonitis. There must be a distinction between infection as a microbiological phenomenon and sepsis as a complex, deleterious, inflammatory host response. Physiologic and metabolic changes during the latter process by taxonomically different organisms or different sources of infection are often clinically indistinguishable. Taurolidine, an amino acid derivate, seems to cover a variety of effects in peritonitis. As secondary peritonitis is associated with a significant cytokine release that is compartementalized in the peritoneal cavity, taurolidine is bactericidal, antiendotoxic, and antiadherent locally and, on the other hand, may modulate the systemic cytokine-mediated inflammatory response after being adsorbed systemically by the peritoneum. Current management of peritonitis can clear the peritoneal cavity of microorganisms and their products but patients continue to die of uncontrolled cytokine-induced systemic inflammation. In patients that undergo daily staged, planned relaparotomies they should not only be treated locally by taurolidine but also systemically by intravenous administration. The latter should, as a sort of sequential therapy, be continued, especially when the peritoneal cavity has been closed after a series of relaparotomies.

    We report here an unusual presentation of peritoneal endometriosis with smooth muscle metaplasia as multiple protruding masses on the lateral pelvic wall. Smooth muscle metaplasia is a common finding in rectovaginal endometriosis, whereas in peritoneal endometriosis, smooth muscle metaplasia is uncommon and its nodular presentation on the pelvic wall is even rarer. To the best of our knowledge, this is the first case of nodular smooth muscle metaplasia occurring in peritoneal endometriosis. As observed in this case, when performing laparoscopic surgery in order to excise malignant tumors of intra-abdominal or pelvic organs, it can be difficult for surgeons to distinguish the metastatic tumors from benign nodular pelvic wall lesions, including endometriosis, based on the gross findings only. Therefore, an intraoperative frozen section biopsy of the pelvic wall nodules should be performed to evaluate the peritoneal involvement by malignant tumors. Moreover, this report implies that peritoneal endometriosis, as well as rectovaginal endometriosis, can clinically present as nodular lesions if obvious smooth muscle metaplasia is present. The pathological investigation of smooth muscle cells in peritoneal lesions can contribute not only to the precise diagnosis but also to the structure and function of smooth muscle cells and related cells involved in the histogenesis of peritoneal endometriosis.

    2015-11-01

    Acute genital edema (AGE) is an infrequent but disruptive complication in patients on continuous ambulatory peritoneal dialysis. It is a common manifestation of dialysate leakage caused by inguinal, umbilical, femoral, or incisional hernias; peritoneal tears; leaks around the dialysis catheter; trauma; fluid overload; and malignancy. The evaluation of AGE begins with a history and physical exam. However, the physical exam in these patients is often indeterminate. Several diagnostic measures exist to evaluate and guide management of AGE occurring during continuous ambulatory peritoneal dialysis but little agreement exists on an optimum method. We have conducted a review of the literature on the evaluation and management of AGE and present a summary of the data. CT peritoneography and peritoneal scintigraphy have been used extensively to evaluate AGE although no comparative studies exist. MRI peritoneography has also been described. CT peritoneography offers more anatomical detail but may not be as sensitive as peritoneal scintigraphy in detecting a peritoneal fluid leak as the cause for AGE. CT is also more costly and subjects the patient to more radiation. MRI is a noncontrast study without radiation risk, but has not been studied to the same degree. If testing is equivocal or bilateral hernias are suspected, diagnostic laparoscopy is helpful and can be combined with hernia repair. Whether the etiology is a leak or tear, low-volume peritoneal dialysis (PD) or cessation of PD for two to four weeks will allow closure. However, hernias almost always require operative repair with mesh usually without disrupting PD.
