Idiopathic achalasia is a rare primary motility disorder of the esophagus. The classical features are incomplete relaxation of a frequently hypertensive lower esophageal sphincter (LES) and a lack of peristalsis in the tubular esophagus. These motor abnormalities lead to dysphagia, stasis, regurgitation, weight loss, or secondary respiratory complications. Although major strides have been made in understanding the pathogenesis of this rare disorder, including a probable autoimmune mediated destruction of inhibitory neurons in response to an unknown insult in genetically susceptible individuals, a definite trigger has not been identified. The diagnosis of achalasia is suggested by clinical features and conf irmed by further diagnostic tests, such as esophagogastroduodenoscopy (EGD), manometry or barium swallow. These studies are not only used to exclude pseudoachalasia, but also might help to categorize the disease by severity or clinical subtype. Recent advances in diagnostic methods, including high resolution manometry (HRM), might allow prediction of treatment responses. The primary treatments for achieving long-term symptom relief are surgery and endoscopic methods. Although limited high-quality data exist, it appears that laparoscopic Heller myotomy with partial fundoplication is superior to endoscopic methods in achieving long-term relief of symptoms in the majority of patients. However, the current clinical approach to achalasia will depend not only on patients' characteristics and clinical subtypes of the disease, but also on local expertise and patient preferences. 展开更多

METHODS: We reviewed the medical records of 9 children with tuberculous peritonitis. RESULTS: Nine patients (5 boys, 4 girls) of mean age 14.2 years were diagnosed with peritoneal tuberculosis. All patients presented with abdominal distention. Abdominal pain was seen in 55.5% and fever in 44.4% of the patients. Four cases had coexisting pleural effusion and two had pulmonary tuberculosis with parenchymal consolidation. Ultrasonography found ascites with septation in 7 patients. Two patients had only ascites without septation. Ascitic fluid analysis of 8 patients yielded serum-ascite albumin gradients of less than 1.1 gr/dL. Laparoscopy and laparotomy showed that whitish tuberculi were the most common appearance. Adhesions were also seen in three cases. The diagnosis of peritoneal tuberculosis was confirmed histo-pathologically in 7 patients and microbiologically in two. Two patients had been diagnosed by ascitic fluid diagnostic features and a positive response to antituberculous treatment. All patients completed the antituberculous therapy without any complications. CONCLUSION: Tuberculous peritonitis has to be clinically suspected in all patients with slowly progressive abdominal distension, particularly when it is accompanied by fever and pain. Laparoscopy and peritoneal biopsy are still the most reliable, quick and safe methods for the diagnosis of tuberculous peritonitis. 展开更多

Capsule endoscopy has revoluzionized the study of the small bowel by providing a reliable method to evaluate, endoscopically, the entire small bowel. In the last six years several papers have been published exploring the possible role of this examination in different clinical conditions. At the present time capsule endoscopy is generally recommended as a third examination, after negative bidirectional endoscopy, in patients with obscure gastrointestinal bleeding. A growing body of evidence suggests also an important role for this examination in other clinical conditions such as Crohn's disease, celiac disease, small bowel polyposis syndromes or small bowel tumors. The main complication of this examination is the retention of the device at the site of a previously unknown small bowel stricture. However there are also some other open issues mainly due to technical limitations of this tool (which is not driven from remote control, is unable to take biopsies, to insufflate air, to suck fluids or debris and sometimes to correctly size and locate lesions).The recently developed double balloon enteroscope, owing to its capability to explore a large part of the small bowel and to take targeted biopsies, although being invasive and time consuming, can overcome some limitations of capsule endoscopy. At the present time, in the majority of clinical conditions (i.e. obscure GI bleeding), the winning strategy seems to be to couple these two techniques to explore the small bowel in a painless, safe and complete way (with capsule endoscopy) and to define and treat the lesions identified (with double balloon enteroscopy). 展开更多

Recently, endoscopic therapy has become widely used as a primary therapeutic option. Initially performed for drainage of pancreatic cysts and pseudocysts, endoscopic treatments were adapted to biliary and pancreatic ducts stenosis. Pancreatic sphincterotomy which allows access to pancreatic ducts was firstly reported. Secondly, endoscopic methods of stenting, dilatation, and stones extraction of the bile ducts were applied to pancreatic ducts. Nevertheless, new improvements were necessary: failures of pancreatic stone extraction justified the development of extra-corporeal shock wave lithotripsy; dilatation of pancreatic stenosis was improved by forage with a new device; moreover endosonography allowed guidance for celiac block, gastro-cystostomy, duodeno-cystostomy and pancreatico-gastrostomy. Although endoscopic treatments are more and more frequently accepted, indications are still debated. 展开更多

A new method to detect multiple outliers in multivariate data is proposed. It is a combination of minimum subsets, resampling and self-organizing map (SOM) algorithm introduced by Kohonen,which provides a robust way with neural network. In this method, the number and organization of the neurons are selected by the characteristics of the spectra, e.g., the spectra data are often changed linearly with the concentration of the components and are often measured repeatedly, etc. So the spatial distribution of the neurons can be arranged by this characteristic. With this method, all the outliers in the spectra can be detected, which cannot be solved by the traditional method, and the speed of computation is higher than that of the traditional neural network method. The results of the simulation and the experiment show that this method is simple, effective, intuitionistic and all the outliers in the spectra can be detected in a short time. It is useful when associated with the regression model in the near infra-red research. 展开更多

Objective The aim of the study was to detect circulating differentiated thyroid cancer (DTC) micrometas-tasis and to investigate the factors influencing their presence in the perioperative thyroiclectomy period. Methods DTC micrometastases in the peripheral blood were detected with flow cytometry, and patient clinical and pathological factors were analyzed in 327 DTC patients. Results Circulating blood micrometastases were present in the peripheral circulation at a higher rate 1 week postoperatively than preoperatively and at 4 weeks postoperatively (P 〈 0.05). The preoperative pres- ence of circulating micrometastasis was associated with the size of the tumor and the presence of lymph node metastasis (P 〈 0.05), but was not related to the degree of tumor differentiation (P 〉 0.05). At 4 weeks postoperatively, the presence of circulating micrometastasis was not associated with tumor size or lymph node stage (P 〉 0.05), but was associated with poorly differentiated tumors (P 〈 0.05). Conclusion The presence of circulating DTC micrometastases correlates to tumor size, lymph node stage, and operative manipulation. The differentiation degree of the tumors were associated with the persistent presence of micrometastasis in the circulating blood. 展开更多

This review aims to outline the most up-to-date knowledge of pancreatic adenocarcinoma risk, diagnostics, treatment and outcomes, while identifying gaps that aim to stimulate further research in this understudied malignancy. Pancreatic adenocarcinoma is a lethal condition with a rising incidence, predicted to become the second leading cause of cancer death in some regions. It often presents at an advanced stage, which contributes to poor five-year survival rates of 2%-9%, ranking firmly last amongst all cancer sites in terms of prognostic outcomes for patients. Better understanding of the risk factors and symptoms associated with this disease is essential to inform both health professionals and the general population of potential preventive and/or early detection measures. The identification of high-risk patients who could benefit from screening to detect pre-malignant conditions such as pancreatic intraepithelial neoplasia, intraductal papillary mucinous neoplasms and mucinous cystic neoplasms is urgently required, however an acceptable screening test has yet to be identified. The management of pancreatic adenocarcinoma is evolving, with the introduction of new surgical techniques and medical therapies such as laparoscopic techniques and neo-adjuvant chemoradiotherapy, however this has only led to modest improvements in outcomes. The identification of novel biomarkers is desirable to move towards a precision medicine era, where pancreatic cancer therapy can be tailored to the individual patient, while unnecessary treatments that have negative consequences on quality of life could be prevented for others. Research efforts must also focus on the development of new agents and delivery systems. Overall, considerable progress is required to reduce the burden associated with pancreatic cancer. Recent, renewed efforts to fund large consortia and research into pancreatic adenocarcinoma are welcomed, but further streams will be necessary to facilitate the momentum needed to bring breakthroughs seen for other cancer sites. 展开更多

AIM:The purpose of this review is to describe the various aspects of primary gastric lymphoma and the treatment options currently available. METHODS:After a systematic search of Pubmed,Medscape and MDconsult,we reviewed and retrieved literature regarding gastric lymphoma. RESULTS:Primary gastric lymphoma is rare however,the incidence of this malignancy is increasing.Chronic gastritis secondary to Helicobacter pylori (H pylori) infection has been considered a major predisposing factor for MALT lymphoma. Immune histochemical marker studies and molecular biology utilizing polymerase chain reaction have facilitated appropriate diagnosis and abolished the need for diagnostic surgical resection.Advances in imaging techniques including Magnetic Resonance Imaging (MRI) and Endoscopic Ultrasonography (EUS) have helped evaluation of tumor extension and invasion. The clinical course and prognosis of this disease is dependent on histopathological sub-type and stage at the time of diagnosis.Controversy remains regarding the best treatment for early stages of this disease.Chemotherapy,surgery and combination have been studied and shared almost comparable results with survival rate of 70-90%.However,chemotherapy possesses the advantage of preserving gastric anatomy. Radiotherapy alone has been tried and showed good results. Stage IIIE,IVE disease treatment is solely by chemotherapy and surgical resection has been a remote consideration. CONCLUSION:We conclude that methods of diagnosis and staging of the primary gastric lymphoma have dramatically improved.The modalities of treatment are many and probably chemotherapy is superior because of high success rate, preservation of stomach and tolerable complications. 展开更多

Many factors influence the treatment strategy for metastatic breast cancer (MBC). Chemotherapy should be administered to patients with hormone receptor-negative tumors, symptomatic visceral metasta- sis, and a short disease-free interval. Sequential single-agent chemotherapy has similar efficacy as combi- nation agents in terms of overall survival and quality of life. Anthracyclines are the cornerstone of first-line treatment for MBC, and taxanes represent the second treatment option after resistance. When progression or intolerable toxicity occurs after optimal treatment, the alternative treatments include capecitabine, vinorel- bine, and gemcitabine. Ixabepilone and eribulin are relatively new effective single agents. A combination of cytotoxic agents for patients with rapid clinical progression can further improve the overall response rate and time to progression compared to single-agent treatment. For patients with MBC who were pretreated with anthracyclines in the neoadjuvant/adjuvant setting, a taxane-containing regimen such as docetaxel plus capecitabine or gemcitabine plus paclitaxel should be administered. Platinum-based therapies such as cisplatin or carboplatin have a role in the treatment of triple-negative breast cancer. Meanwhile, the efficacy of the addition of targeted drugs such as iniparib, bevacizumab, and catuximab to chemotherapy remains unproven. Maintenance chemotherapy is routinely recommended in clinical practice at present. Patients who were previously treated with paclitaxel and gemcitabine have better progression-free and overall sur- vival with maintenance chemotherapy according to a Korean phase III clinical trial. Sequential maintenance treatment with capecitabine monotherapy after capecitabine-based combination chemotherapy (X-based X) appears favorable based on a series of domestic studies. 展开更多

Objective Angiogenesis is known to be essential for the survival,growth,invasion,and metastasis of lung cancer cells. Vascular endothelial growth factor(VEGF) is an important factor regulating angiogenesis of non-small cell lung cancer(NSCLC); however,its pathologic features and significance are unclear. In this study,the tissue VEGF expression levels and its gene transcriptional status,as well as circulating VEGF levels,were investigated in patients with lung disease. Methods VEGF protein and m RNA expression levels in 38 lung tissue samples were analyzed by immunohistochemistry and reverse transcription-polymerase chain reaction(RT-PCR),respectively. Circulating VEGF levels were detected quantitatively by an enzyme linked immuno-sorbent assay. Results The level of VEGF expression was significantly higher in lung cancer tissue than in the corresponding paracancerous or non-cancerous tissues. The average level of VEGF-positive staining was 76% in tissue samples from NSCLC patients; the levels were 89% in tissue samples from stage III patients and 92% in stage IV patients. High VEGF expression was also evident in cases with lymph node metastasis(84%),distant metastasis(90%),and lower differentiation degree(89%). VEGF m RNA in cancerous tissues was represented predominantly by the VEGF121 and VEGF165 isoforms. Circulating VEGF levels were significantly higher in NSCLC patients [(840 ± 324) pg/m L] than in patients with benign lung diseases [(308 ± 96) pg/m L] or in healthy individuals serving as controls [(252 ± 108) pg/m L]. Conclusion The over-expression of lung VEGF and its gene transcription status should be useful molecular indicators for NSCLC diagnosis. 展开更多

Objective: To study the pathologic features of plasmacytoid transitional cell carcinoma of the bladder, and to analyze the diagnostic features, criteria for differential diagnosis and the clinical significance of the tumor. Methods: Two cases of bladder plasmacytoid transitional cell carcinoma were studied. Routine paraffin sections with HE staining, Pap smear and immunohistochemistry by S-P method were observed under a light microscope. Pathological and clinical data were analyzed by comparison with early reported cases in literatures. Results: A characteristic feature of this tumor was of deep invasion in the lamina propria and/or muscularis propria, in addition to the component of carcinoma in situ in the mucosa, when tumors were diagnosed. The histological pattern and cytological features showed similarity to a plasmacytoid tumor. The tumor cells were strongly positive for AE1/AE3, CEA and CK18. The prognosis appeared to be worse than ordinary transitional cell carcinoma. Conclusion: The plasmacytoid transitional cell carcinoma of bladder is rare but has typical pathological, immunohistological and clinical features. Pathologists should be aware of this kind of primary tumor of bladder. 展开更多

Objective To investigate the association between preoperative,operative,and postoperative factors and persistent pleural effusion after the extracardiac Fontan procedure. Methods Ninety-five consecutive patients diagnosed with univentricular heart underwent extracardiac connection using Gore-Tax conduits at the Department of Children’s Heart Centre,Justus-Liebig-University Giessen in Germany from June 1996 to July 2007. The outcome measures were duration and volume of chest tube drainage after surgical intervention. The investigated factors included age and weight at the time of operation,anatomical diagnosis,preoperative oxygen saturation,mean pulmonary artery pressure,ventricular end-diastolic pressure,fenestration,cardiopulmonary bypass time,conduit size,postoperative pulmonary artery pressure,administration of angiotensin-converting enzyme inhibitors,and postoperative infection. Associations between these factors and persistent pleural effusion after the extracardiac Fontan procedure were analyzed. Results Every patient suffered postoperative effusion. The median duration of postoperative chest tube drainage was 9 days (range,3-69 days),and the median volume was 12 mL·kg-1·d-1 (range,2.0-37.5 mL·kg-1·d-1). Thirty-seven (38.9%) patients had pleural drainage for more than 15 days,and the volume in 35 (36.8%) patients exceeded 25 mL·kg-1·d-1. Nineteen (20%) patients required placement of additional chest tubes for re-accumulation of pleural effusion after removal of previous chest tubes. Fifteen (17.8%) patients were hospitalized again due to pleural effusion after discharge. The median length of hospital stay after the operation was 14 days (range,4-78 days). Multivariate analysis results showed that non-fenestration,low preoperative oxygen saturation,and postoperative infections were independent risk factors for prolonged duration of pleural drainage (P<0.05). Long cardiopulmonary bypass time,non-fenestration,small conduit size,and low preoperative oxygen saturation were independent risk factors for excessive volume of pleural drainage (P<0.05).Conclusions For reduing postoperative duration and volume of pleural drainage following Fontan procedure,it seems to be important to improve the preoperative oxygen saturation,use large size of conduit,shorten cardiopulmonary bypass time,and make fenestration during the operation,as well as avoid postoperative infections. 展开更多

In 1959, the concept of brain death (BD) or irreversible coma was described by Mollaret and Goulon (1959). The first guideline (the Harvard criteria) for deciding BD was established in 1968 (Ad Hoc Committee of the Harvard Medical School, 1968). This concept has been accepted worldwide although its fundamental meaning is not exactly globally uniform yet. Some countries (e.g., the US) view BD as "whole brain death", while others (e.g., the UK) as brain-stem death. The guidelines for the diagnosis of BD also differ among countries, even among hospitals in the same country. 展开更多

A manual search was then done for other contributions, including abstracts, between January 1965 and June 1997. [WT5”BX] Results. [WT5”BZ]Eighty seven Chinese cases of EMF were collected in this paper. There were 49 men and 38 women, with a mean age of 28±13 years(range, 8 to 68 years). The distribution of the cases is mainly in the south of China. Combined right and left ventricular disease occurs in 48 percent of cases, with pure right ventricular involvement occurring in 42 percent and pure left ventricular involvement in the remaining 10 percent of patients who are examined postmortem. The diagnosis of EMF was confirmed in 21 cases at autopsy, and in 66 cases by echocardiography, angiocardiography, and/or endomyocardial biopsy which showed the characteristic changes. Clinically, right sided disease is the commonest variety. Endocardiectomy and tricuspid(n=7) or mitral(n=1) valves replacement have been performed in 8 patients. There were 2 operative deaths.

Abdominal cocoon,the idiopathic form of sclerosing encapsulating peritonitis,is a rare condition of unknown etiology that results in an intestinal obstruction due to total or partial encapsulation of the small bowel by a f ibrocollagenous membrane.Preoperative diagnosis requires a high index of clinical suspicion.The early clinical features are nonspecif ic,are often not recognized and it is diff icult to make a def inite pre-operative diagnosis.Clinical suspicion may be generated by the recurrent episodes of small intestinal obstruction combined with relevant imaging f indings and lack of other plausible etiologies.The radiological diagnosis of abdominal cocoon may now be conf idently made on computed tomography scan.Surgery is important in the management of this disease.Careful dissection and excision of the thick sac with the release of the small intestine leads to complete recovery in the vast majority of cases. 展开更多

The most common symptoms were upper abdominal pain and upper abdominal dis-com fort,which appeared in20casesand17casesrespectively,an d the most common sign was abdominal masses.B-ultrasound and CT are the most commonly used means for preoperative examination,with posit ive rates of97.8%and100%respectively.Op-e rative mortality was2%.Five-year survival rate of radical surgery of maligna nt cases was75%.Immuno-histological examinations showed that tumors rich i n multi-peptide linked hormones,neuron-specific eno-lase and chromaffin were in65%cases,90.6%and73.3% respectively.The positive rates of insulin,glucagons,somatostatin,pancreat ic polypeptide,gastrin and vasoactive intestinal peptide were68.2% ,51.2%,42.9%,40% ,25%and15.8%respectively.Conclusion.Nonfuncti onal islet cell tumors lack diagnostic specificity.Ultrasound and CT are primar y examination methods.Immunohistological analysis indicates different hormones ,but lacks the presence of related clinical symptoms.Surgery is an effective treatment for nonfunctional islet cell tumors,and even for those with distal m etastasis,immediate surgical removal and treatment can improve prognosis. 展开更多
