Epithelioid inflammatory myofibroblastic sarcoma (EIMS) is a rare variant of the inflammatory myofibroblastic tumor. It has an aggressive clinical course and a high rate of recurrence. EIMS primarily affects children and young adults. Hereby, we report this entity in a 4-month-old infant who presented with an abdominal mass. Imaging studies revealed a large hypodense mesentery-based lesion involving the right half and mid-region of the abdomen. The mass with an attached segment of the small bowel was excised in toto. Grossly, a large encapsulated tumor was identified arising from the mesentery of the small bowel. The histological examination showed a tumor consisting of epithelioid to spindle cells loosely arranged in a myxoid background with numerous blood vessels and lymphoplasmacytic inflammatory infiltrate. On immunohistochemistry, the tumor cells showed positivity for ALK1 (nuclear), desmin, SMA, CD68, and focal positivity for CD30. A final diagnosis of EIMS of the small intestine was rendered. To the best of our knowledge, this case is the youngest reported case in literature.

ABSTRACT Objective: To report a case of a child with primary immunodeficiency who at eight years developed digestive symptoms, culminating with the diagnosis of a neuroendocrine tumor at ten years of age. Case description: One-year-old boy began to present recurrent pneumonias in different pulmonary lobes. At four years of age, an immunological investigation showed a decrease in IgG and IgA serum levels. After the exclusion of other causes of hypogammaglobinemia, he was diagnosed with a Common Variable Immunodeficiency and started to receive monthly replacement of human immunoglobulin. The patient evolved well, but at 8 years of age began with epigastrium pain and, at 10 years, chronic persistent diarrhea and weight loss. After investigation, a neuroendocrine tumor was diagnosed, which had a rapid progressive evolution to death. Comments: Medical literature has highlighted the presence of gastric tumors in adults with Common Variable Immunodeficiency, emphasizing the importance of early diagnosis and the investigation of digestive neoplasms. Up to now there is no description of neuroendocrine tumor in pediatric patients with Common Variable Immunodeficiency. We believe that the hypothesis of digestive neoplasm is important in children with Common Variable Immunodeficiency and with clinical manifestations similar to the case described here in the attempt to improve the prognosis for pediatric patients.

RESUMO Objetivo: Relatar um caso de criança portadora de imunodeficiência primária que, aos oito anos, desenvolveu sintomas digestivos, culminando com o diagnóstico de tumor neuroendócrino aos dez anos de idade. Descrição do caso: Menino, com um ano de idade, começou a apresentar pneumonias de repetição em diferentes lobos pulmonares. Aos quatro anos, a investigação imunológica mostrou diminuição dos níveis séricos de IgG e IgA. Após exclusão de outras causas de hipogamaglobulinemia, teve diagnóstico de imunodeficiência comum variável, passando a receber reposição mensal de imunoglobulina humana. Evoluiu bem, porém, aos oito anos, começou com epigastralgia e, aos dez anos, diarreia crônica persistente e perda de peso. O quadro culminou com o diagnóstico de tumor neuroendócrino intestinal, de rápida progressão, com óbito do paciente. Comentários: A literatura tem chamado a atenção para tumores gástricos em adultos com imunodeficiência comum variável, alertando para a importância do diagnóstico precoce e da pesquisa de neoplasias digestivas. Até o momento, não há descrição de tumor neuroendócrino em pacientes pediátricos portadores de imunodeficiência comum variável. Acredita-se ser importante a hipótese de neoplasia digestiva diante de crianças com imunodeficiência comum variável e com manifestações clínicas semelhantes ao caso descrito, na tentativa de melhorar o prognóstico para pacientes pediátricos.

INTRODUCCIÓN: El tumor miofibroblástico inflamatorio (TMI) es una neoplasia benigna infrecuente, de comportamiento clínico impredecible. OBJETIVOS: describir 3 casos de TMI diagnosticados entre marzo 2014 y enero 2018 en Hospital Clinico San Borja Arriaran, y realizar una revisión actualizada de la literatura. CASO 1: Adolescente de género masculino de 14 años de edad, hospitalizado por dolor abdominal, diagnosticado de invaginación yeyunoyeyunal secundaria a un tumor de pared intestinal. La histología fue compatible con un tumor miofibroblástico inflamatorio. CASO 2: Adolescente de género femenino, edad 12 años, hospitalizada por neumonía y dolor lumbar en estudio asociado a pérdida de peso. Se diagnosticó una masa retroperitoneal que comprometía el músculo psoas derecho, músculos paravertebrales, vértebras, riñón derecho y diafragma ipsilateral. Se efectuó biopsia por punción cuyo resultado fue compatible con un tumor miofibroblástico inflamatorio. CASO 3: Preadolescente de género femenino de 11 años de edad, hospitalizada para estudio de infección del tracto urinario a repetición. Se identificó un tumor vesical y la biopsia mostró ser compatible con tumor miofibroblástico inflamatorio. CONCLUSIÓN: Debido al comportamiento variable del tumor miofibroblástico inflamatorio, el manejo de este dependerá de la localización, la expresión del anaplasic like lymphoma (ALK), el comportamiento del tumor y la posibilidad de resección.

INTRODUCTION: The inflammatory myofibroblastic tumor is an infrequent benign neoplasm with unpredictable cli nical behavior. OBJECTIVES: to describe three clinical cases at the San Borja Arriarán Clinical Hospital between March 2014 and January 2018 and to carry out an updated review of the literature. CASE 1: 14-year-old male adolescent, hospitalized due to abdominal pain, diagnosed with jejunojejunal intus susception secondary to an intestinal wall tumor. The histology was compatible with an inflamma tory myofibroblastic tumor. CASE 2: 12-year-old female adolescent, hospitalized due to pneumonia and low-back pain under study associated with weight loss. A retroperitoneal mass was diagnosed involving the right psoas muscle, paravertebral muscles, vertebrae, right kidney, and ipsilateral dia phragm. A puncture biopsy was performed and the result was compatible with an inflammatory myofibroblastic tumor. CASE 3: 11-year-old female pre-adolescent, hospitalized to study recurrent urinary tract infection. A bladder tumor was identified, and the biopsy showed compatibility with inflammatory myofibroblastic tumor. CONCLUSION: Due to the variable behavior of the inflammatory myofibroblastic tumor, its management will depend on the location, expression of the anaplastic lymphoma kinase (ALK), tumor behavior, and the resection possibility.

PURPOSE: Several endoscopic resection therapies have been applied for the treatment of rectal carcinoid tumors. However, there is currently no consensus regarding the optimal strategy. We performed a meta-analysis to compare the efficacy and safety of endoscopic mucosal resection (EMR) or modified EMR (m-EMR) versus endoscopic submucosal dissection (ESD) for the treatment of rectal carcinoid tumors. MATERIALS AND METHODS: PubMed, Web of Science, Medline, Embase and CNKI were searched up to the end of January 2014 in order to identify all studies on the effects of EMR (or m-EMR) and ESD on rectal carcinoid tumors. RESULTS: A total of fourteen studies involving 782 patients were included. The pooled data suggested a significantly higher rate of pathological complete resection among patients treated with ESD or m-EMR than those treated with EMR [odds ratio (OR)=0.42, 95% confidence interval (CI): 0.25-0.71; OR=0.10, 95% CI: 0.03-0.33, respectively], while there was no significant difference between the m-EMR group and ESD group (OR=1.19, 95% CI: 0.49-2.86); The procedure time of ESD was longer than EMR or m-EMR groups [mean differences (MD)=-11.29, 95% CI: -14.19 - -8.38, MD= -10.90, 95% CI: -18.69 - -3.11, respectively], but it was insignificance between the EMR and m-EMR groups. No significant differences were detected among the treatment groups with regard to complications or recurrence. CONCLUSION: The results of this meta-analysis suggest that treatment of rectal carcinoid tumors with ESD or m-EMR is superior to EMR, and the efficacy of m-EMR is equivalence to ESD treatment. However, more well-designed studies are needed to confirm these findings.

Introduction: Primary intestinal lymphoma (PIL) is defined as an extranodal lymphoma arising in the intestine. This study includes 11 PILs. Objectives: The objective of this study was to evaluate the clinicopathological characteristics of primary non-Hodgkin's lymphoma (NHL) in the small and large intestine. All cases were reclassified according to the World Health Organization classification of lymphoma in 2001. Immunohistochemistry (IHC) was used to confirm the histopathological diagnosis. Materials and Methods: Eleven cases of primary non-Hodgkin in the small and large intestine were studied retrospectively in a 5 year period. There were seven cases of resected intestinal specimens and four biopsy specimens. Five cases from ileum and two cases each from caecum and duodenum and one case each from jejunum and duodenum. Hematoxylin and eosin stained sections were studied with light microscopy and IHC for CD5, 20, 21 and cyclin D1 were done. Results: It is a retrospective study of 11 cases of intestinal lymphomas. Abdominal pain and abdominal lump were two main common presenting symptoms. NHLs were more common in the small intestine. PILs are common in adults (75% above 46 years) with male preponderance. All were NHLs and B-cell type. Five cases were diffuse large B-cell lymphoma and four cases each were mucosa-associated lymphatic tissue lymphoma and follicular lymphoma. One case was lymphomatoid polyposis or mantle cell lymphoma. Conclusion: PILs is rare and differs significantly from their gastric counterpart, not only in pathology but also with regard to clinical features, management and prognosis. Due to the lack of characteristic symptoms and a low incidence rate, PIL is misdiagnosed until serious complications occur, such as perforation and bleeding and hence needs to be accurately diagnosed.

Biopsy of rectal carcinoid tumor is commonly taken before endoscopic resection. However the preceding biopsy can inhibit complete resection by causing blurred tumor border and fibrosis of the tissue. The objective of the study was to investigate the effect of preceding biopsy on complete endoscopic resection in rectal carcinoid tumor. It was also determined if rectal carcinoid tumors can be macroscopically distinguished by endoscopy. We reviewed retrospectively the records of patients with rectal carcinoid tumor who had undergone an endoscopic treatment at our hospital, during a 7-yr period. The resection margin was clear in 57 of 98 cases. The preceding biopsy was taken in 57 cases and the biopsy was significantly associated with the risk of incomplete tumor resection (OR, 3.696; 95% CI, 1.528-8.938, P = 0.004). In 95.9% of the cases, it was possible to suspect a carcinoid tumor by macroscopic appearance during initial endoscopy. The preceding biopsy may disturb complete resection of rectal carcinoid tumor. In most cases, the carcinoid tumor could be suspected by macroscopic appearance. Therefore the preceding biopsy is not essential, and it may be avoided for the complete resection.

El pólipo fibroide inflamatorio es un tumor benigno poco frecuente del tubo digestivo, descripto por Vanek en 1949. Son lesiones de etiología desconocida, originadas en la submucosa. Están formadas por células mononucleares y mesenquimatosas con citoplasma fusocelular, con una importante proporción de eosinófilos. Sus síntomas son variables, dependiendo de su localización, y son una r ara causa de intususcepción intestinal en adultos. Presentamos el caso de una mujer de 82 años, que sufrió una rara intususcepción de intestino delgado, originada en un pólipo fibroide inflamatorio.

Inflammatory fibroid polyps are non-frequent benign lesions, described by Vanek in 1949, originated in the sub mucosa of the gastrointestinal tract. They have an uncertain origin and they are formed of fibroblastic and mesenchymal proliferations with an important eosinophilic proportion. Depending on where are they localized, could present different type of symptoms. The inflammatory fibroid polyps are one of the rare benign conditions causing intestinal intussusception in adults.We present the case of a 82 years old woman, who presented an intestinal intussusception due to an inflammatory fibroid polyp localized in the small bowel.

We report three elderly patients with follicular lymphoma in situ (FLIS) each highlighting a unique pattern of disease presentation and progression. The first patient had incidentally detected FLIS with peripheral blood spill and yet had an 11-year uneventful follow up. The second patient with an overt follicular lymphoma (FL) developed high-grade transformation in jejunum with FLIS extensively involving the Payers patches. The third patient had a FLIS but that qualified as higher grade and was treated in spite of lack of overt FL mainly because of higher grade and patient subsequently did develop overt FL. The first case of typical FLIS confirms that peripheral blood spill does not connote poor prognosis in FLIS, the second case illustrates that FLIS may colonize mucosa-associated lymphoid tissue as part of homing in process of a disseminated FL and the third case validates the aggressive nature of high-grade FLIS.

OBJECTIVE: Description of some of the clinical pathological characteristics of neuroendocrine tumors of the gastroenteropancreatic tract in Brazilian patients. INTRODUCTION: Neuroendocrine tumors arise in many organs and share common pathological features. In 2010, the World Health Organization published a new classification for neuroendocrine tumors using a three-tiered system that applies the terms neuroendocrine tumor Grade 1, neuroendocrine tumor Grade 2, and neuroendocrine carcinoma. The tumor grades are based on their mitotic rate and the Ki-67 index. In Brazil, information on neuroendocrine tumors of gastroenteropancreatic tract is scarce. METHODS: This study investigated clinicopathological features of 773 Brazilian gastroenteropancreatic neuroendocrine tumor cases from all the geographic regions of Brazil. All of the cases emerged from the files of a single institution (a large pathology reference laboratory) between 1997 and 2009. In addition, the gastroenteropancreatic neuroendocrine tumors were graded according to the new 2010 World Health Organization classification. RESULTS: Overall there were a higher number of neuroendocrine tumors in female over male. The lower ages were seen in patients with appendiceal tumors. The most common anatomic location involved was stomach followed by small and large intestines. All cases involving the appendix were of grade 1 and 92.1 percent of the neuroendocrine tumors of the esophagus were neuroendocrine carcinomas (grade 3). CONCLUSIONS: In this series, the proportion of NET cases in the total number of surgical pathology cases at our institution over the past 12 years is increasing.

Existen evidencias que tanto los ácidos biliares como el Helicobacter pylori en la mucosa gástrica son capaces de desencadenar un proceso inflamatorio que según su intensidad y persistencia favorecen la aparición de fallas y mutaciones en la replicación celular que se expresan desde una metaplasia, displasia hasta un cáncer. Se realizó un estudio epidemiológico observacional, descriptivo, prospectivo de corte transversal en el Instituto de Gastroenterología, en pacientes con reflujo duodenogástrico y ácidos biliares totales elevados, con el objetivo de conocer la asociación entre la metaplasia intestinal y la presencia o no de Helicobacter pylori. Al concluir la investigación se observó que la metaplasia estuvo presente en 48,7 por ciento de los 39 pacientes estudiados, que existió una asociación estadísticamente significativa (p<0,05) en la distribución de la bacteria en los pacientes con y sin metaplasia intestinal, que los pacientes con reflujo duodenogástrico, a pesar de tener una lesión histológica, presentaron resultados negativos en cuanto a la presencia de Helicobacter pylori. En las muestras con diagnóstico histológico de gastritis crónica severa y atrófica, el 75 por ciento presentaban Helicobacter pylori. La localización de la metaplasia intestinal fue mayor en la región antral (84,3 por ciento). En los pacientes con reflujo duodenogástrico la presencia de Helicobacter pylori no parece estar asociada a grados intensos de metaplasia, aunque el microorganismo se encuentre en todas las categorías, mientras que cuando no hay, la metaplasia tiende a ser menos severa. En el 100 por ciento de los casos la densidad de la bacteria fue ligera

The cytotoxic and cancerous action of bile acids on gastric mucosa is a very interesting subject within the gastroduodenal diseases due to they are able to alter the membrane, the cellular metabolism, to give rise to a inflammatory process, to increase the proliferation, the cell apoptosis and the DNA damage, that according to its intensity and persistence, favor the appearance of failures and mutations in cell replication. With the discovery and characterization of Helicobacter pylori it is considered that according to its intensity and the time of persistence in gastric mucosa provokes damages with failures and cellular mutations. In this sense, a prospective and descriptive study was conducted in the Institute of Gastroenterology in patients presenting with duodenogastric and high total bile acids to know the association between the intestinal metaplasia and the presence or not of Helicobacter pylori. Metaplasia was present in the 48.7 percent of the 39 study patients, that there was a statistically significant association (p< 0.05) in Helicobacter pylori distribution in patients with and without intestinal metaplasia; that patients with duodenogastric reflux, despite of a histological lesion also had a greater frequency of negative results as regards the presence of Helicobacter pylori. In samples with histological diagnosis of severe and atrophic chronic gastritis, 75 percent, respectively, had Helicobacter pylori and in consequence, there was a significant association between presence or not of microorganism and the chronic gastritis intensity. Intestinal metaplasia location was higher in antral region (84.3 percent) and also with a higher ratio of microorganism positivity. In patients with duodenogastric reflux, presence of Helicobacter pylori don't seems to be associated with intense degrees of intestinal metaplasia, although the microorganism is present in all categories, but when there is not Helicobacter pylori, intestinal metaplasia to tend to ...

O transplante de órgãos se tornou parte importante da medicina moderna. O transplante de intestino (ITx) foi introduzido no final da década de 1960 como um procedimento heróico para tratar falência do intestino. O Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo foi um dos pioneiros mundiais neste procedimento. Com a evolução biotecnológica na medicina, o transplante de intestino emergiu na década de 1990 como a única e permanente opção terapêutica para pacientes com falência intestinal irreversível. Àquele tempo, os resultados clínicos eram, ainda, desapontadores, principalmente devido às altas taxas de infecção pós-operatória e rejeição do enxerto. Entretanto, houve um grande desenvolvimento do transplante intestinal e multivisceral graças à melhoria da terapia imunossupressora, ao refinamento das técnicas cirúrgicas e dos cuidados pós-transplantes. O objetivo deste estudo é oferecer um panorama sobre quando o ITx deve ser indicado e sobre como o procedimento deve ser realizado...

Organ transplantation has become a substantial part of modern medicine. Intestinal transplantation (ITx) was introduced in the late sixties as a heroic procedure to treat intestinal failure. The Clinic Hospital of University of São Paulo Medical School is one of the world’s pioneer in this procedure. With the biotechnological evolution in medicine, intestinal transplantation emerged in the 1990s as the only curative, permanent therapeutic option for patients with irreversible intestinal failure. At that time, the clinical results were also disappointing mainly due to the high rates of post-operative infectious complications and graft rejection. However, the development of intestinal and multivisceral transplantation has been profound owing to the progress in immunosuppressive therapy, refinement of surgical techniques and post-transplant care. This study aims to give a general overview about when the ITx must be considered an option of treatment and how it must be done...

Small bowel neoplasms are rare, accounting for approximately 3-6 percent of all primary malignancies of the gastrointestinal tract. MDCT-E is an imaging modality that combines the advantages of enteroclysis and helical CT, allowing the detection of small bowel diseases wherever they are located (intraluminal, intramural, or extramural). The aim of our study was to assess the reliability of MDCT-E in the detection of small bowel neoplasms. In our institution, MDCT-E was used to study 600 patients admitted for suspicion of small bowel diseases, between January2005 and May 2008. A total of 22 (3, 6 percent) small bowel neoplasms were identified, all confirmed by histological examination. The neoplasms found in this series were adenocarcinoma (n: 4), lymphoma (n: 3), carcinoid tumor (n: 3), benign GIST (n: 2), benign hamartomatous polyps (n: 2) and secondary small bowel tumors (n: 8). MDCT-E appears to be a reliable method in the detection of small bowel neoplasms, allowing tumor staging tobe determined during the same procedure.

Los tumores de intestino delgado (ID) son raros, representando aproximadamente 3-6 por ciento de las neoplasias del tubo digestivo. La E-TC es una técnica que combina las ventajas de la enteroclisis con las de la TC multicorte, con el potencial de demostrar alteraciones intraluminales, murales y extraintestinales. El objetivo de nuestro estudio fue evaluar el potencial diagnóstico de la E-TC en la detección de tumores de ID. En nuestra institución se realizaron 600 E-TC desde Enero del 2005 a Mayo del 2008. Un total de 22 pacientes (3,6 por ciento) presentaron hallazgos tomográficos compatibles con tumores de ID, todos confirmados histológicamente. Los tumores encontrados en esta serie fueron; adenocarcinoma (n:4), linfoma (n:3), tumor carcinoide (n:3), tumor estromal gastrointestinal benigno (n:2), pólipos hamartomatosos (n: 2) y compromiso neoplásico secundario (n:8). Esta serie corrobora el valor de la E-TC como técnica de imagen de elección en la detección de tumores de ID, con la posibilidad de etapificación en el mismo procedimiento.

In this study a 31 y/o woman who was housewife, came from Mazandaran and lived in Behshahr is presented. Patient's complaints were diarrhea, bloating, abdominal pain and weight loss. Abdominal radiography showed loop dilatation. In primary Para clinic assessments she had Alb: 2.8, Ca: 6.4, P: 2.3 and PTH: 201. Considering malabsorption in early evaluation, upper endoscopy was done. Intestinal folds were disappeared in second and third part of duodenum in endoscopic view and duodenal biopsy was done. Then pathological assessment revealed a large accumulation of intraepithelial lymphocytes and obvious villus atrophy that was accordant to celiac sprue. She was advised to be on gluten free diet. After about 1 month, She was referred because of sever lower extremities edema. Serum albumin was checked that was 2. Enlarged mesenteric lymph nodes were detected in sonography. Considering non- responding treatment, IHC staining of intestinal biopsy was performed with celiac sprue complication suspicion. Therefore the patient was referred to chemotherapy center with the diagnosis of T-cell lymphoma following celiac sprue. She was spent 6 course chemotherapy with CHOP regimen and radiotherapy

Small bowel carcinoid tumors are more common in the distal ileum and they are multiple in 30 percent of cases. The most common clinical manifestation is abdominal pain and the treatment of choice is surgical excision. We report a 63 years old female consulting for abdominal pain. An intestinal transit by computed axial tomography revealed multiple images compatible with small bowel carcinoid tumors. She had a surgical excision of the involved intestinal segment and the pathological study confirmed the imaging diagnosis. In the follow up, this patients has been asymptomatic.

A male, 5-year-old Jindo dog underwent enterectomy and enteroanastomosis due to ileus of the intestine at a local veterinary hospital. Grossly, the excised intestine showed markedly thickened multinodular masses in the serosal layer of the upper part, and soft-to-firm, creamcolored neoplastic masses that displayed extensive nodular mucosal protuberances into the lumen. The neoplastic masses were filled with large round cells that were ovoid in shape and they had pale and/or hyperchromatic nuclei. The neoplastic cells had mainly infiltrated into the mucosal and submucosal layers, and they had diffusely invaded the muscular and serosal layers. Therefore, the diagnosis of canine multiple intestinal malignant lymphomatous polyposis was made based on the gross and histopathological findings. The origin of these tumor cells was determined to be B-cells since they were positive for anti-CD20.

Gastrointestinal stromal tumors (GISTs) are rarely noted in association with neurofibromatosis-1 (NF-1, von Recklinghausen disease) as an individual gastrointestinal manifestation. We report here a case of multiple GISTs with an abundant skeinoid fiber in the jejunum of a 43-year-old woman diagnosed as NF-1. Histologically, the tumors were composed of uniform spindle-shaped cells with a fascicular pattern, almost indistinguishable from the histology characteristic of usual GISTs. However, multiple synchronous tumor occurrence, abundant skeinoid fiber, and presence of microscopic miniatures of stromal tumors are additional characteristic features of this case.

Wistar male rats, 3 months of age were given ad-libitum a nutritionally adequate diet and demineralized drinking water. The Molybdenum (Mo) and Tungsten (W) were provided in the drinking water at 200 ppm concentration. Intestinal tumors were induced by 1,2-dimethylhydrazine (DMH) given subcutaneously as 16 weekly doses at 20 mg/kg body weight. Mo in the form of (NH4)6 Mo7O24 4H2O or W in the form of (Na2WO4) were provided in the drinking water two months before the first DMH treatment and were continued during 4 months more until the last DMH treatment. Three months after the last carcinogen injection, all animals were sacrificed and examined for intestinal tumors. The number, size and location of the tumors were recorded and the pathology was examined. The addition of Mo to the drinking water induced an increase of hepatic Mo content. At the end of the second month, the hepatic content of Mo was 5.61 ppm, compared with control and W groups (2.18 and 0.96 ppm, respectively). A significantly lower incidence of tumors was observed in the Mo group (47), compared with the control group given DMH alone (105) and W group (113). On the other hand, the Mo group showed a significant decrease in the numbers of multiple tumors per rat.

Metastasis into the hepatic hemangioma is a rare occurrence. We report a unique case of metastasis of intestinal carcinoma into hepatic hemangioma in a case of 65 year old male who presented with anorexia, weakness and headache. The postmortem examination revealed adenocarcinoma in the ileocaecal region. The liver showed a subcapsular hemangioma of 1.5 cms. diameter which on microscopic examination revealed metastasis of adenocarcinoma. The is the first documentation of metastasis in hepatic hemangioma. Such cases may pose problems of diagnostic difficulties and thus may result in mismanagement.
