The lesions usually present in the nasal cavity and adjacent tissues, however, the disease originates from the gastrointestinal or genitourinary tract in 25% of cases. Since rectal involvement in ENKTL is rare, rectal symptoms in the course of ENKTL are often misdiagnosed and considered to be related to benign diseases such as rectal fistula or perianal abscess.CASE SUMMARY We report the case of a 24-year-old Han Chinese female who initially presented with a perianal abscess that was subsequently diagnosed as nasal type ENKTL.Due to typical perianal pain, perianal abscess was diagnosed and surgical incision and drainage were performed. After recurrent, severe anal hemorrhages leading to hypovolemic shock and multiple surgeries, a diagnosis of ENKTL was made. The patient's condition gradually deteriorated, and she died shortly after initiation of chemotherapy.CONCLUSION Systemic and neoplastic diseases should be included in the differential diagnosis of any potentially benign perianal abscess complicated with recurrent hemorrhages.展开更多

文摘In this paper we illustrate the potential of the repertory grid technique as an instrument for case formulation and understanding of the personal perception and meanings of people with a diagnosis of psychotic disorders.For this purpose,the case of James is presented:A young man diagnosed with schizophrenia and personality disorder,with severe persecutory delusions and other positive symptoms that have not responded to antipsychotic medication,as well with depressive symptomatology.His case was selected because of the way his symptoms are reflected in his personal perception of self and others,including his main persecutory figure,in the different measures that result from the analysis of his repertory grid.Some key clinical hypotheses and possible targets for therapy are discussed.
文摘In order to remain competitive in software industry, software engineers need to continuously improve their proficiency. Personal Software Process (PSPSM) provides a strong concept which helps software engineers inspecting and improving themselves. Yet, when being applied on an undergraduate computer engineering course, several complex mathematical calculations from PSP official exercises could encumber the performance of students who do not possess adequate mathematics background. This paper reports a result of implementing PSP course for undergraduate computer engineering students in Chiang Mai University, Thailand.
文摘 Among various types of cervical spondylopathy, the one involving the vertebral arteries is frequently encountered in the middle-aged and the old people. It is often accompanied with arteriosclerosis and high blood viscosity, and clinically it is difficult to be treated. From March 1996 to December 2000, the authors hadtreated 72 cases of cervical spondylopathy of this type and achieved satisfactory therapeutic effects shown by clinical symptoms and indicated by the trans-cranial Doppler ultrasonic examination (TCD). This is reported as follows.

文摘With the service industry and information technology developing, Service innovation occurs continually in business today. It is important for service firms to understand the service's business and process; customer knowledge including needs, expectations and experiences. However, employees are key factor to collect the customer's advice. At the same time, employees may organize customers for the new service. So, the integration of employees and customers will help service firm in the way of developing a new service and upgrading a service. The paper describes some models to explain the relation based on some literatures and give some advices for service firms. At last, we introduce an IT service case
文摘BACKGROUND Simultaneous cerebral and myocardial infarction with arterial involvement has not been reported in hypereosinophilic syndrome(HES).Here,we report a patient with HES that was also associated with acute ischemic stroke,myocardial infarction,and arterial involvement of the left common carotid artery,vertebral arteries,posterior cerebral artery,and coronary artery.CASE SUMMARY A 64-year-old male patient was admitted with headache and right lower extremity weakness.Laboratory tests indicated eosinophilia.Brain magnetic resonance imaging(MRI)showed bilateral and multiple acute infarcts in the border zones.Electrocardiography revealed that T wave was inverted and that the concentration of troponin I was significantly elevated above normal levels.Cardiac echocardiography showed an ejection fraction of 69%with mitral and tricuspid mild regurgitation.Computed tomography angiography detected multiple and localized instances of mild stenosis in the left common carotid artery bifurcation,bilateral vertebral arteries(V5 segment),and the posterior cerebral artery(P2 segment).These were observed together with multiple non-calcified and mixed plaques as well as luminal stenosis in the left circumflex artery,left anterior descending artery,and right coronary artery.The patient was treated with oral methylprednisolone and clopidogrel,after which the absolute eosinophil count fell rapidly to a normal level.After one month,a second brain MRI showed a partial reduction in the size and number of the lesions.CONCLUSION HES can masquerade as ischemic stroke,myocardial infarction,and arterial vascular involvement.The patient reported here recovered very quickly when his eosinophil blood count returned to normal.Early diagnosis and rapid reduction of eosinophils may lead to a good prognosis.

文摘BACKGROUND Extranodal natural killer(NK) T-cell lymphoma(ENKTL), nasal type is a rare subtype of extranodal non-Hodgkin lymphoma characterized by vascular damage and necrosis. The lesions usually present in the nasal cavity and adjacent tissues, however, the disease originates from the gastrointestinal or genitourinary tract in 25% of cases. Since rectal involvement in ENKTL is rare, rectal symptoms in the course of ENKTL are often misdiagnosed and considered to be related to benign diseases such as rectal fistula or perianal abscess.CASE SUMMARY We report the case of a 24-year-old Han Chinese female who initially presented with a perianal abscess that was subsequently diagnosed as nasal type ENKTL.Due to typical perianal pain, perianal abscess was diagnosed and surgical incision and drainage were performed. After recurrent, severe anal hemorrhages leading to hypovolemic shock and multiple surgeries, a diagnosis of ENKTL was made. The patient's condition gradually deteriorated, and she died shortly after initiation of chemotherapy.CONCLUSION Systemic and neoplastic diseases should be included in the differential diagnosis of any potentially benign perianal abscess complicated with recurrent hemorrhages.
文摘In this paper, we develop a mathematical model of the COVID-19 pandemic in Burkina Faso. We use real data from Burkina Faso National Health Commission against COVID-19 to predict the dynamic of the disease and also the cumulative number of reported cases. We use public policies in model in order to reduce the contact rate, this allows to show how the reduction of the daily report of infectious cases goes, so we would like to draw the attention of decision makers for a rapid treatment of reported cases.

文摘BACKGROUND Lichen planus(LP)with distribution of lesions along Blaschko’s lines is a rare entity,accounting for 0.24%-0.62%of all patients.Unilateral distribution of lesions in arm,leg,trunk,and waist is even less common.Approximately 10%of patients with LP manifest nail lesions.CASE SUMMARY A 20-year-old woman presented to our department with polygonal,purpuric,flattopped papules over the right arm,right leg,and right side of trunk and waist for the last 5 mo.The patient initially developed nail deformation in the left middle finger with no obvious cause,followed by development of blue-purple and red maculopapular rash with pruritus.During the disease course,the skin lesions aggravated and spread to several segments due to scratching.The lesions showed unilateral distribution along the Blaschko’s lines.The diagnosis of LP along Blaschko’s lines was established based on dermoscopy and skin biopsy.Her cutaneous lesions considerably improved after 4-wk treatment with intramuscular glucocorticoid,oral acitretin,topical glucocorticoid,and retinoids.CONCLUSION Cases of LP involving multiple segments of the body along the Blaschko’s lines with nail damage are rare.
文摘BACKGROUND Mantle cell lymphoma(MCL)is a subtype of Non-Hodgkin’s lymphoma(NHL).MCL frequently affects extranodal sites while endobronchial involvement is uncommon.Only 5 cases of MCL with endobronchial involvement have been previously reported.CASE SUMMARY A 56-year-old male patient arrived at the hospital complaining of a dry cough.A mass in the right upper lobe of the lung was revealed in Chest computed tomography(CT).Right lung hilar and mediastinal lymphadenopathies were also found by CT scan.The patient was diagnosed with central-type lung cancer with multiple lymph node metastases after positron emission tomography(PET)CT scan examination.The fiber optic bronchoscope examination revealed diffuse neoplasm infiltration in the inlet of the right up lobar bronchus.The patient was finally diagnosed with MCL based on the bronchoscopy and mediastinoscopy biopsy results.CONCLUSION MCL could masquerade as central type lung cancer.An endobronchial biopsy examination is necessary for the early diagnosis of MCL.
文摘BACKGROUNDRelapsing polychondritis (RP) is a rare, long-term, and potentially life-threateningdisease characterised by recurrent paroxysmal inflammation that can involve anddestroy the cartilage of the external ear, nose, larynx, and trachea.CASE SUMMARYWe here report a case of RP involving solely the tracheobronchial cartilage ring(and not the auricular. nasal or articular cartilage) complicated by Sjögren's syndrome in a 47-year-old female whose delayed diagnosis caused a sharpdecline in pulmonary function. After corticosteroid treatment, her pulmonaryfunction improved.CONCLUSIONIn such cases, our experience suggested that 18F-fluorodeoxyglucose positronemission tomography/computed tomography (18F-FDG PET/CT) and fiberopticbronchoscopy should be used to diagnose airway chondritis as relapsing polychondritisin the early phase of disease.
