Cardiohistological Findings in Refeeding Syndrome.

Severe eating disorders may develop refeeding syndrome, which sometimes resembles severe cardiac dysfunction. A woman in her thirties was admitted to our hospital because of cardiogenic shock. Transthoracic echocardiography showed reduced left ventricular systolic function. In her medical history, she had been diagnosed with refeeding syndrome. A ventricular endocardial biopsy was performed to exclude other cardiac diseases. A histological examination showed conspicuously atrophied cardiomyocytes with nuclear swelling and irregularities; the myocardial sequence was disturbed with fibrosis. Immunostaining revealed that lipid droplet markers, adipose triglyceride lipase, and perilipin 2 were poorly observed in the cardiomyocytes, while expression of both proteins was attenuated in fibroblasts within the myocardial layer. The abnormal metabolism of fatty acids was the presumed cause of cardiac dysfunction.

Results of Endometrial Biopsy and Its Impact on Survival Data in Patients with High-Risk Uterine Sarcoma.

Background: There are conflicting data regarding the detection rate of high-risk uterine sarcoma (HRUS) by endometrial biopsy. In addition, there are no studies in the literature on its impact on the chosen surgical approach and survival. Methods: This study includes 415 patients with HRUS. Of these, 178 (42.9%) patients had undergone endometrial biopsy. We analyzed the detection rate of endometrial biopsy and its impact on surgical approach and survival data. Results: Correct specific histologic diagnosis was achieved in only 30.0% of LMS and 33.3% of HGESS/UUS. Other uterine sarcoma, unspecified malignant mesenchymal tumor, carcinosarcoma or carcinoma were found in 45% of LMS and 78.2% of HGESS/UUS. As a result of the histologic findings, the rate of inadequate surgery was reduced by up to 19.9%. As tumor morcellation was performed significantly less often with biopsy (32.5% with vs. 55.4% without biopsy, p < 0.001), the locoregional recurrence-free interval remained unaffected between the two groups (p = 0.81). This is obviously an advantage of biopsy, although it does not affect the local recurrence rate in morcellated patients. Conclusions: Indicated endometrial biopsy is an important step in the diagnosis of HRUS, despite its low detection rate. It helps to avoid inappropriate surgical procedures but does not affect OS.

Histological diagnosis from kidney transplant biopsy can contribute to prediction of graft survival.

AIM: The primary aim of this study was to in depth examine if the histological findings in a transplanted kidney biopsy can predict the prognosis for the graft and the patient. The secondary aim was to extend knowledge of the impact of time elapsed on biopsy findings. METHODS: Data from 1462 patients were merged from a kidney transplantation registry and a biopsy registry during 1 January 2007 and 30 September 2017. Kaplan-Meier analysis and multivariate Cox-regression analysis were performed and hazard ratios (HR) with 95% confidence intervals (CI) were presented. RESULTS: Compared to normal biopsy findings, graft survival after biopsy (gsaBiopsy) was shorter for patients with glomerular diseases (HR 8.2, CI:3.2-21.1), rejections (HR 4.2, CI:1.7-10.3), chronic changes including IFTA (HR 3.2, CI:1.3-8.0), acute tubular injuries (HR 3.0, CI:1.2-7.8), and borderline changes (HR 2.9, CI:1.1-7.6). Sub-analysis of rejections showed shorter gsaBiopsy for chronic TCMR (HR 4.7, CI:1.9-11.3), active ABMR (HR 3.6, CI:1.7-7.7) and chronic ABMR (HR 3.5, CI:2.0-6.0). Patients with TCMR Banff grade II (HR 0.35, CI:0.20-0.63) and grade I (HR 0.52, CI:0.29-0.93) had a better gsaBiopsy compared to all other types of rejections. CONCLUSION: Shorter gsaBiopsy was noted in kidneys with glomerular diseases, rejections, acute tubular injuries and borderline changes. TCMR Banff rejections grade I and II were associated with a better prognosis.

Multiple Intracranial Aneurysms Caused by Myxoma: Case Report and Literature Review.

OBJECTIVE: We present a case of multiple myxoma-related intracranial aneurysms and reviewed the recent relevant literature to investigate their natural course and develop a reasonable treatment algorithm. METHODS: We have reported a new case of multiple myxoma-related intracranial aneurysms and performed a search of current studies (2001 to the present) in PubMed. The keywords used were as follows (single words or combinations): neoplastic aneurysm, oncotic aneurysm, aneurysm, and myxoma. Only patients with multiple aneurysms resulting from cardiac myxoma and with adequate follow-up information pertinent to the analysis were included. RESULTS: A total of 41 patients, including our present patient, were studied. Of the 41 patients, 28 had received conservative treatment as the primary choice. Most lesions (n = 22) were stable during follow-up, except for 3 in which aneurysm evolution was observed. A total of 8 patients had undergone microsurgery, including aneurysm resection in 3, aneurysm clipping in 2, clipping followed by resection in 2, and aneurysm trapping in 1. Endovascular treatment was performed in 2 patients. Radiation therapy was used in 1 patient, and the parent artery proved to be occluded at the 1-year follow-up examination. A combination of chemotherapy and microsurgery was used in 1 patient. All the cases that had been managed aggressively were stable during further follow-up. CONCLUSION: The prognosis was good for most patients with multiple myxoma-related intracranial aneurysms, and most myxoma-related aneurysms were stable. Conservative treatment and routine follow-up are recommended for most patients. However, for patients with evolving or ruptured aneurysms, invasive treatment, including open surgery and endovascular treatment, should be considered.

Concordance between sequential transbronchial lung cryobiopsy and surgical lung biopsy in patients with diffuse interstitial lung disease.

BACKGROUND: Increasing evidence indicates the utility of transbronchial lung cryobiopsy (TBLC) for the diagnosis of interstitial lung disease (ILD). However, only one study has compared TBLC and surgical lung biopsy (SLB) performed on the same patients. METHODS: We identified seven patients with ILD with TBLC and SLB. We evaluated the clinical characteristics and made a pathological diagnosis based on the official ATS/ERS/JRS/ALAT clinical practice guideline of idiopathic pulmonary fibrosis with both TBLC and SLB. RESULTS: Six cases were diagnosed as Usual interstitial pneumonia (UIP) in both TBLC and SLB. One case was diagnosed as indeterminate for UIP with TBLC and probable UIP with SLB. Etiological diagnosis with TBLC and SLB were concordant in 2 cases of idiopathic pulmonary fibrosis (IPF) but discordant for other diagnoses. Major histological findings of UIP including dense fibrosis, peripheral distribution, and fibroblastic foci showed high concordance between TBLC and SLB, which implies that TBLC can reliably detect these features. In contrast, loose fibrosis, cellular infiltration, and airway disease showed poor concordance between the two methods. CONCLUSION: Our study showed that TBLC is useful for UIP diagnosis but not for other ILD. With a multidisciplinary approach, diagnosis of IPF may be determined by TBLC, whereas ILD other than IPF may require SLB.

Rare breast and subcutaneous metastases from pancreatic neuroendocrine tumor: a case report.

BACKGROUND: Neuroendocrine tumors are a group of rare neoplasms, and the pancreatic neuroendocrine tumors (PNETs) represent only 1-2% of all pancreatic malignant tumors. The most common sites of these tumors include the gastrointestinal tract, lung, adrenal gland, and thyroid gland. Moreover, the most common sites of PNET metastases are the lymph nodes, liver, spleen, and bone. A 40-year-old woman with pT3N1 PNET underwent surgical excision of the lesion (12 cm, at the level of the pancreatic body and tail). Postsurgical treatment included chemotherapy and radiation, both of which the patient showed a good tolerance for. After a 12-month disease-free interval, however, the patient reported the development of a lesion in her left breast and a small lesion in the left posterior region of her neck. The lesions were surgically excised, and the histological findings characterized both as pancreatic neuroendocrine metastatic poorly differentiated neoplasms (G3). A re-staging CT scan showed multiple metastases in the left axillary, clavicular, and latero-cervical lymph nodes, as well as diffuse osteolytic-osteoblastic bone metastases, almost mimicking the behavior of a primitive breast tumor. CONCLUSION: This case of breast and subcutaneous metastases from PNET should prompt awareness of potential metastatic lesions in unusual locations.

Correlation between histological findings and endoscopic findings in patients with ulcerative colitis: Basal plasmacytosis is an important finding suggesting active inflammation.

AIMS: In clinical practice, patients of ulcerative colitis showing divergence between the histological findings and endoscopic findings are often encountered. Therefore, we compared histological findings with endoscopic findings, indicating the severity of the inflammation of ulcerative colitis. METHODS AND RESULTS: The study group comprised 191 patients (527 biopsy specimens) with ulcerative colitis who underwent lower gastrointestinal endoscopy with biopsy in our hospital from July 2015 to June 2016. Endoscopic findings of the mucosa at the biopsy site were classified into seven levels according to the severity of inflammation: noninflamed mucosa, red signs, loss of visible vascular patterns, granular mucosa, friable mucosa, spontaneous bleeding, and erosions/ulcers (E/U). All biopsy samples were examined for the presence or absence of five histological findings (basal plasmacytosis [BP], neutrophil infiltration, cryptitis, crypt abscess [CAb], and E/U), and the results were contrasted with endoscopic findings. The 191 patients comprised 123 (64.4%) males and 68 (35.6%) females, with a median age of 47 years (range, 8-82). Among the 527 specimens, the detection rates of BP, CAb, and E/U in mucosa with endoscopic E/U were 58.5, 27.4, and 18.3%. The detection rate of BP in mucosa with red signs was 22.4%; in mucosa, with loss of visible vascular patterns, it was 16.9%; in granular mucosa, it was 35.7%, and in mucosa with E/U, it was 58.5%. BP was frequently seen in severely inflamed mucosa associated with E/U on endoscopic examination. CONCLUSION: BP was considered an important finding, suggesting the presence of active and severe inflammation.

Non-alcoholic fatty liver disease in patients with autoimmune hepatitis.

BACKGROUND AND AIM: The incidence of non-alcoholic fatty liver disease (NAFLD) is increasing all over the world. NAFLD develops in patients with liver disease, including patients with autoimmune hepatitis (AIH). NAFLD and AIH have some similar laboratory and histological findings. The aim of this study was to elucidate the characteristics of AIH patients with NAFLD. METHODS: We re-evaluated the nationwide survey performed in Japan in 2015 of AIH patients diagnosed between 2009 and 2013. RESULTS: A total of 1151 subjects (144 men and 1007 women) were enrolled in the present study. The overall prevalence of NAFLD was 17.0%. Compared to AIH without NAFLD, AIH patients with NAFLD had the following characteristics: (i) low female-to-male ratio, (ii) older age, (iii) mild elevation in hepatobiliary enzymes, (iv) histologically progressive fibrosis and mild plasma cell infiltration or mild lobular hepatitis, (v) lower prevalence of prednisolone administration and higher prevalence of ursodeoxycholic acid administration, (vi) higher levels of hepatic enzymes and immunoglobulin G after treatment, and (vii) similar prevalence of autoimmune and malignant complications. CONCLUSION: AIH patients with NAFLD have many features that are different from AIH patients without NAFLD. Understanding these differences is essential for the proper diagnosis and treatment of AIH patients with NAFLD.

Indications for salvage surgery during treatment for intracranial germ cell tumors.

This study retrospectively reviewed our single institute experience to clarify the optimal indication and timing of salvage surgery. Retrospective analysis of 159 consecutive cases with germ cell tumors identified 20 cases with salvage surgery. These cases were classified based on the radiological response to neoadjuvant treatment before salvage surgery into increase (growing group, five cases), no change (stable group, seven cases), and decrease (shrinkage group, eight cases) in tumor size. Changes in tumor markers, histological findings, and the pattern of failure after salvage surgery were reviewed. Growing teratoma syndrome (GTS) is defined as enlargement of tumor consisting of mature teratoma after chemotherapy with normalization of tumor markers. In growing group, two cases presented GTS, whereas other three cases did not fulfill the criteria for GTS. All cases in stable and shrinkage group had elevated levels of tumor markers at presentation and decreased levels after neoadjuvant treatment. Histologically, sparse components of mature teratoma with extensive fibrosis were found in cases with GTS and seven of eight cases in shrinkage group, whereas mature teratoma without fibrosis was found in six of seven cases in stable group. Six cases recurred after salvage surgery. We identified three factors as risks for recurrence after salvage surgery, as follows: (1) growing lesion which did not fulfill the criteria for GTS, (2) non-normalized level of tumor marker before salvage surgery, and (3) residual germinoma component. In conclusion, salvage surgery is recommended for patients with GTS, or with normalized tumor markers in stable or shrinkage group.

Clinicopathological analysis of methotrexate-associated lymphoproliferative disorders: Comparison of diffuse large B-cell lymphoma and classical Hodgkin lymphoma types.

Patients with rheumatoid arthritis often develop methotrexate-associated lymphoproliferative disorders (MTX-LPD) during MTX treatment. MTX-LPD occasionally regresses spontaneously after simply discontinuing MTX treatment. In patients without spontaneous regression, additional chemotherapy is required to avoid disease progression. However, the differences between spontaneous and non-spontaneous regression have yet to be elucidated. To clarify the factors important for spontaneous regression, we analyzed the clinicopathological features of 51 patients with rheumatoid arthritis who developed MTX-LPD (diffuse large B-cell lymphoma [DLBCL]-type [n = 34] and classical Hodgkin lymphoma [CHL]-type [n = 17]). We examined the interval from MTX discontinuation to the administration of additional chemotherapy. The majority of DLBCL-type MTX-LPD patients (81%) exhibited remission with MTX discontinuation alone. In contrast, the majority of CHL-type MTX-LPD patients (76%) required additional chemotherapy. This difference was statistically significant (P = 0.001). However, overall survival was not significantly different between DLBCL-type and CHL-type (91% vs 94%, respectively; P > 0.05). Thus, the morphological differences in the pathological findings of MTX-LPD may be a factor for spontaneous or non-spontaneous regression after discontinuation of MTX.

Hallazgos citológicos y factores de riesgo en citología cervical anormal en mujeres de pescadores del norte peruano, 2015 / Cytological findings and risk factors in abnormal cervical cytology in female fishermen from northern Peru, 2015

Introducción: El cáncer de cuello uterino es un problema de salud pública mundial, y es la segunda causa de muerte en el Perú; su estudio se ha realizado más en poblaciones de grandes ciudades, dejando de lado otras poblaciones que podrían tener un riesgo significativo. Objetivo: Determinar la prevalencia y los factores asociados a los hallazgos citológicos anormales de cuello uterino en las mujeres de pescadores de una ciudad del norte peruano. Métodos: Investigación transversal analítica de datos secundarios, se realizó un muestreo por conveniencia en las mujeres con vida sexual activa de una población semi urbana del norte peruano. La variable principal fue el hallazgo de lesiones pre invasoras e invasoras del cuello uterino según la citología observada, se cruzó con otras variables sociales, ginecológicas y sexuales; encontrando estadísticos de asociación crudos y ajustados. Resultados: De las 144 encuestadas, el 20% tuvo una alteración citológica y el 26% no se habían realizado la prueba hace más de 3 años. El 14% fue positivo para lesión escamosa intra epitelial de bajo grado, el 1% tuvo un carcinoma escamoso invasor. Al realizar el análisis multivariado, se obtuvo una asociación entre lesión citológica y VPH (p<0,001), el tener inflamación severa (p<0,001), el tener un germen (p=0,001) y el haber iniciado las relaciones sexuales a los 14 años o menos (p=0,024), ajustado por el usar anticonceptivos y el haberse realizado un Papanicolaou. Conclusiones: Se reporta algunos factores asociados en una población sexualmente activa, que reflejan una gran prevalencia de lesiones asociada a factores que deben ser intervenidos.

Introduction: Cervical cancer is a global public health problem, and is the second leading cause of death in Peru; the study was conducted more in populations of large cities, leaving aside other populations that could have a significant risk. Objective: To determine the prevalence and factors associated with abnormal cervical cytologic findings in women of fishermen in a city in northern Peru. Methods: Cross-sectional analytical research of secondary data, convenience sampling was performed in women with active sex life in a semi urban population of northern Peru. The principal variable was the finding of pre invasive and invasive cervical lesions observed by cytology, crossed with other social, gynecological and sexual variables; statistical finding of crude and adjusted association. Results: Of the 144 respondents, 20% had a cytological alteration and the 26% had not taken the test over 3 years ago. 14% were positive for squamous intra epithelial lesion low grade, 1% had an invasive squamous carcinoma. When performing multivariate analysis, an association between cytological lesion and HPV (p<0.001), having severe inflammation (p<0.001), having a germ (p=0.001) and initiating sexual intercourse at age 14 or less (p=0.024), adjusted for contraceptive use and Pap tests have been done. Conclusions: Some associated factors in a sexually active population, reflecting a high prevalence of injury associated with factors that have to be operated.

Association of first-trimester angiogenic factors with placental histological findings in late-onset preeclampsia.

OBJECTIVE: To explore in women with late-onset preeclampsia (PE) the association between maternal levels of angiogenic/antiangiogenic factors in the first trimester of pregnancy and histological findings attributable to placental underperfusion (PUP). METHODS: A nested case-control cohort study was conducted in 73 women with pregnancies complicated by late-onset PE (>34 weeks at delivery) matched with controls. First trimester uterine artery Doppler (UtA); maternal levels of placental growth factor (PlGF) and soluble fms-like tyrosine kinase-1 (sFlt-1) were retrieved. Placentas were histologically evaluated using a hierarchical and standardized classification system. One-way ANOVA with linear polynomial contrast or linear-by-linear association test was performed to test the hypothesis of a linear association across study groups (controls, PE without PUP and PE with PUP). RESULTS: In 54 (74%) placentas, 89 placental histological findings qualifying for PUP were found. Across study groups, significant values were observed in maternal levels of decreased PlGF (MoM values: 1.53, 1.41 and 1.37; p < 0.001), increased sFlt-1 (MoM values: 3.11, 3.11 and 3.22; p = 0.002), increased sFlt-1/PlGF ratio (MoM values: 2.3, 2.3 and 2.44; p < 0.001), abnormal UtA Doppler (MoM values: 1, 1.26 and 1.32; p < 0.001), and worse perinatal outcomes in terms of gestational age at delivery, cesarean section for not reassuring fetal status, birth weight and neonatal acidosis. DISCUSSION: In late-onset PE an imbalance of circulating angiogenic and anti-angiogenic factors already present at 8-10 weeks of pregnancy was associated with histological findings reflecting placental insufficiency. An early first trimester screening by angiogenic factors might help to identify patients with placental involvement among late-onset PE cases. CONCLUSION: In late-onset preeclampsia, first-trimester uterine Doppler and circulating levels of angiogenic/antiangiogenic factors are associated with placental underperfusion.

Alcoholic hepatitis histological score has high accuracy to predict 90-day mortality and response to steroids.

INTRODUCTION/OBJECTIVES: A histological classification system (AHHS) has been recently proposed to predict 90-day mortality in patients with alcoholic hepatitis (AH). We analyzed the spectrum of histological features in patients with AH and assessed the ability of AHHS for predicting both response to steroids and 90-day mortality. METHODS: Retrospective study of patients admitted to our tertiary centre between 2010 and 2014 with biopsy-proven AH. Histological features were analyzed and AHHS value was calculated. Kaplan-Meyer curves were calculated to assess the ability of AHHS to predict response to steroids and 90-day mortality. RESULTS: We included 34 patients (70.6% men, mean age 48.5±8.9 years). Transjugular liver biopsy was performed 3.5±2.9 days after admission. Presence of bilirubinostasis (p=0.049), degree of bilirubinostasis (p<0.001), absence of megamitochondria (p<0.001) and degree of polymorphonuclear infiltration (p=0.018) were significantly associated with higher mortality at 90 days. Patients who responded to steroids had a significantly lower AHHS value than non-responders (5.4±0.9 vs 8.1±1.1, p=0.003). AAHS value was significantly higher in patients who died compared to patients who survived at 90 days (9.0±0.7 vs 5.0±0.9, p<0.001). AHHS predicted response to steroids [AUROC 0.90 (CI95% 0.742-1.000), p=0.004] and 90-day mortality [AUROC 1.0 (CI95% 1.0-1.0), p<0.001] with high accuracy. CONCLUSIONS: In this cohort of patients, presence and degree of bilirubinostasis, absence of megamitochondria and degree of PMN infiltration were significantly associated with 90-day mortality. AHHS had a high accuracy for predicting response to steroids and 90-day mortality in this cohort of patients.

A comparison of the ultrasonography images of the joints of patients with rheumatoid arthritis and the corresponding synovial histological findings.

OBJECTIVES: The objective of this study is to investigate whether ultrasonography (US) images of joints that underwent surgery reflected the synovial histological findings or clinical indicators and to compare the results of the findings related to large joints (LJs) with those of small joints (SJs). METHODS: The operations were performed on 215 joints in 177 patients with rheumatoid arthritis (RA). The 215 joints included 64 LJs and 151 SJs. The joints with the power Doppler (PD) signal grades 0 and 1 were assigned to group L, while those with grades 2 and 3 were assigned to group H. The Rooney score, Disease Activity Score-erythrocyte sedimentation rate (DAS28), serum matrix metallopeptidase 3 (MMP-3), and C-reactive protein (CRP) levels were determined. RESULTS: The Rooney score, DAS28, MMP-3, and CRP levels of the LJs were significantly lower in group L than in group H. In group H, similar results were found in the LJs and SJs, with a significant increase in the disease activity, CRP and MMP-3 levels and the histological findings in comparison to group L. CONCLUSIONS: The PD signal grade was one of the indicators that reflected the degree of synovitis in the histological findings of the active joints of RA patients.

Proposal for novel histological findings of colorectal liver metastases with preoperative chemotherapy.

This study aimed to clarify the histological characteristics related to preoperative chemotherapy for colorectal liver metastases (CRLM). Sixty-three patients with CRLM were divided into two groups: CRLM with chemotherapy (41 cases, group A) and CRLM without chemotherapy (22 cases; surgical treatment alone, group S) to identify the histological differences associated with chemotherapy. In addition, we investigated the effects of combination chemotherapy on the histology of metastatic lesions. Infarct-like necrosis (ILN), three-zonal changes, and cholesterol clefts were more frequent in group A than in group S (P < 0.05). ILN and three-zonal changes were more common in the 5-FU with leucovorin and oxaliplatin (FOLFOX), or 5-FU with leucovorin and irinotecan (FOLFIRI) with or without additional bevacizumab groups than in group S (P < 0.05). Cholesterol clefts in the FOLFOX or FOLFIRI with bevacizumab group and foamy macrophages in the FOLFOX or FOLFIRI group were more common than in group S (P < 0.05). Cases with more than three of the four histological findings--i.e. ILN, three-zonal changes, cholesterol clefts, and foamy macrophages--were more frequent in the FOLFOX or FOLFIRI with or without additional bevacizumab groups than in group S (P < 0.05). We showed histological findings for every representative chemotherapy regimen for CRLM to clarify the effects of preoperative chemotherapy.

Heterotopic gastric mucosa of upper oesophagus: evaluation of 12 cases during gastroscopic examination.

INTRODUCTION: Oesophageal heterotopic gastric mucosa mostly presents in the upper part of the oesophagus. It is commonly under-diagnosed because of its localisation. AIM: To expose the association between heterotopic gastric mucosa and endoscopic features of the upper gastrointestinal tract. MATERIAL AND METHODS: A total of 1860 upper endoscopic examinations performed between January 2012 and July 2013 were analysed retrospectively. Endoscopic features and histological examinations of 12 heterotopic gastric mucosa (HGM) of the upper oesophagus were documented and evaluated retrospectively. RESULTS: There were 7 (58%) male and 5 (42%) female patients aged between 22 and 80 years with a mean age of 43.2 years. Heterotopic gastric mucosa was present in 12 (0.6%) of all patients. We were able to perform biopsy for histopathological observation on 8 (66%) of the 12 patients in which HGM was seen during endoscopy. Five (42%) patients with heterotopic gastric mucosa had oesophagitis. Los Angeles Grade A oesophagitis was found in all patients, and histologically proven Barrett's oesophagus was detected in only one patient. CONCLUSIONS: When a patient has ongoing dyspeptic complaints and reflux symptoms despite the treatment, one should be careful about possible HGM during upper gastrointestinal endoscopy. The point to be taken into consideration for patients who have metaplasia or dysplasia within HGM may need to be considered for surveillance.

Total spondylectomy following carbon ion radiotherapy to treat chordoma of the mobile spine.

The main form of treatment of a chordoma of the mobile spine is total en bloc spondylectomy (TES), but the clinical results are not satisfactory. Stand-alone carbon ion radiotherapy (CIRT) for bone and soft-tissue sarcomas has recently been reported to have a high rate of local control with a low rate of local recurrence. We report two patients who underwent TES after CIRT for treating a chordoma in the lumbar spine with good medium-term outcomes. At operation, there remained histological evidence of viable tumour cells in both cases. After the combination use of TES following CIRT, neither patient showed signs of recurrence at the follow-up examination. These two cases suggest that CIRT should be combined with total spondylectomy in the treatment of chordoma of the mobile spine.

Hallazgos clínicos, endoscópicos e histológicos asociados a la infección por Helicobacter pylori considerando los genotipos CAG A y VAC A en pacientes con dispepsia: Servicio de Gastroenterología Hospital Central Universitario “Antonio María Pineda” Barquisimeto Estado Lara / Clinical, endoscopic and histological findings associated with helicobacter pylori infection considering genotypes CAG A and VAC A in patients with dyspepsia: Gastroenterology Department Hospital Central Universitario

La dispepsia afecta la calidad de vida de muchos pacientes y en muchos casos está asociada a la infección por Helicobacter pylori. Esta bacteria es reconocida como el agente causal de la gastritis crónica, se asocia al desarrollo de úlceras gástrica y duodenal y está relacionada con el desarrollo de cáncer gástrico. Como objetivo primario se planteó establecer los hallazgos clínicos, endoscópicos e histológicos asociados a la infección por Helicobacter pylori considerando los genotipos cag A y vac A en pacientes con dispepsia que acudieron al Servicio de Gastroenterología del Hospital Central Universitario “Antonio María Pineda”. Se trata de un estudio epidemiológico descriptivo de corte transversal. La población estuvo conformada por los pacientes con dispepsia que acudieron al servicio y el muestreo fue de tipo no probabilístico intencional, puesto que se tomó a la población que consultó con síntomas dispépticos y que cumplieron con los criterios de inclusión y exclusión establecidos. Dichos pacientes se interrogaron sobre síntomas dispépticos, se les realizó endoscopia digestiva superior, se describieron los hallazgos endoscópicos y se les tomó muestra para estudio histológico y de genotipificación. Se encontró una incidencia de infección por H. pylori de 98,5%, la infección predominó en el sexo femenino, los genotipos cag A positivos y las formas alélicas m1/s1 son los más frecuentes en la población estudiada y, los mismos se asocian con gastritis crónica, úlceras gástricas y metaplasia intestinal incompleta...

Dyspepsia affects quality of life for many patients and often is associated with Helicobacter pylori infection. This bacterium is recognized as the causative agent of chronic gastritis, is associated with development of gastric and duodenal ulcers and, with the development of gastric cancer. Primary objective was raised to establish the clinical, endoscopic and histological findings associated with Helicobacter pylori infection considering genotypes cag A and vac A in patients with dyspepsia who attended the Gastroenterology Service of Hospital Central Universitario “Antonio María Pineda”. This is a cross-sectional descriptive epidemiological study. The population consisted of patients with dyspepsia who attended the gastroenterology service. The sampling was intentionally non-probabilistic, since we only took the people who consulted with dyspeptic symptoms and met the established criteria of inclusion and exclusion. These patients were questioned about dyspeptic symptoms, underwent upper gastrointestinal endoscopy, endoscopic findings were described and samples were taken for histology and genotyping. We found an incidence of H. pylori of 98.5%, infection prevailed in females, the genotypes cag A positive and m1/s1 allelic forms are most frequent in the population studied and, the same is associated with chronic gastritis, gastric ulcers and intestinal metaplasia incomplete...

The role of somatostatin in 67 consecutive pancreatectomies: a randomized clinical trial.

BACKGROUND: Somatostatin has been found to be effective in the prevention of postoperative complications in pancreatic surgery. It can inhibit the pancreatic secretions that, quite often, are responsible for complications during the postoperative period. METHODS: We randomized 67 patients in 2 groups. In the study group (n = 35), somatostatin was administered 30 minutes prior to surgery as well as intraoperatively and postoperatively. No medication was given to the control group (n = 32). Biopsies were taken and processed for electron microscopy and ultrastructural morphometric analysis. RESULTS: Administration of somatostatin reduced the exocrine granule number, and the patients suffered from fewer postoperative complications. CONCLUSIONS: Somatostatin reduces granule number and size of pancreatic cells, which can partially explain the prophylactic effect of the drug on early complications of pancreatic surgery, and which is confirmed by the clinical findings.
