Gastric 99mTc-Methylene Diphosphonate Accumulation in a Patient With Primary Upper Gastrointestinal Tract Melanoma.

Unexpected extraosseous uptake is common on Tc-methylene diphosphonate bone scintigraphy, but accumulation by primary upper gastrointestinal tract malignant melanoma is rarely reported. The present case is a 58-year-old woman with a 10-day history of diffuse bone pain and weakness. Her bone scintigraphy showed unexpected diffuse gastric tracer uptake.

[Research progress in strategy of lateral femoral offset reconstruction in total hip arthroplasty].

As an important indicator of total hip arthroplasty (THA) the rate and degree of offset reconstruction play an important role in improving the prognosis and life quality of patients. The reconstruction of femoral offset is closely related to reserved length of calcar femorale, the head and neck length of prosthesis, angle degree of neck shaft and whether lower limb is isometric. Reconstruction strategy includes making a meticulous and standard measurement before the surgery, predicting the reserved length of calcar femorale, selecting a prosthesis with approximate anatomical neck-shaft angle and reconstructing offset by adjusting the head and neck length of the prosthetic during the operation.

Recognition of fibrous dysplasia of bone mimicking skeletal metastasis on 18F-FDG PET/CT imaging.

Purpose: Fibrous dysplasia of bone (FDB) reveals intense 18F-FDG uptake mimicking metastases on 18F-FDG PET/CT. We reviewed sites of FDB revealed by 18F-FDG PET/CT imaging to allow identification of this abnormality.

Materials And Methods: Eleven patients (7 male, 4 female, aged 16-78 years) were evaluated after 55 MBq (0.

[Differentiation of malignant and benign superficial lymph nodes by dual time point 18F-FDG PET].

Objective: To evaluate the value of dual time point 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) in differentiating malignant and benign superficial lymph nodes.

Methods: Sixty-eight patients with ninety superficial lymph nodes were examined. Whole body 18F-FDG PET imaging was performed one hour (early) after FDG injection and repeated one hour (delayed) later but only for the interesting areas.

[Secular trend of nosocomial pneumonia in an university hospital in Zhengzhou].

Objective: To investigate the secular trend of infection rate, risk factor exposure rates for nosocomial pneumonia (NP), and to evaluate the nosocomial infection surveillance and control programs efficacy in an university hospital from 1993 to 2000.

Methods: All 126 665 hospitalized patients from 1993 to 2000 were studied for NP. The independent risk factors for NP were analyzed by using case-control study method and logistic regression technique.
