OBJECTIVETo assess the features of fluorine-18 fluorodeoxyglucose (FDG) uptake in patients with benign pulmonary nodules.

METHODSFrom October 1998 to July 2004, 47 patients with benign pulmonary nodules were imaged with FDG-positron emission tomography (PET). Diagnoses were confirmed by surgery. FDG-PET data was analyzed by visual method and semi-quantitive method. When pulmonary nodules with abnormal FDG intake appeared in PET scans confirmed by visual method, their maximum and mean standard uptake value (SUVmax and SUVmean) and SUV of normal lung (SUVlung) were measured using semiquantitative method.

RESULTSTwenty-one cases showed nothing abnormal in PET scans, including 17 calcification and fibrosis, 2 hamartomas and 2 sclerosing hemangiomas. 26 pulmonary nodules were detected by FDG-PET (17 active tuberculous, 6 inflammatory pseudotumors, 3 cryptococcosis). FDG uptake of these 26 nodules was higher than that of normal lung (SUVmax, SUVmean and SUVlung were 3.04 +/- 1.65, 2.48 +/- 1.35 and 0.40 +/- 0.07, respectively, P < 0.001). Correlations were not found between FDG uptake and nodule size or SUV of normal lung or age or blood glucose level in these 26 patients (P > 0.05). SUV in 9 cases (9/26, 35%) were beyond 2.5.

CONCLUSIONSSome benign pulmonary nodules were FDG avid.

OBJECTIVETo investigate the value of fluorine-18 fluorodeoxyglucose (FDG)-positron emission tomography (PET) in carcinoma of cardia or fundus of stomach.

METHODSFrom April 1999 to April 2005, 57 patients with carcinoma of cardia or fundus of stomach were imaged with FDG-PET. FDG-PET imaging were analyzed by visual method combined with semiquantitative analysis. The results were compared with pathological findings and follow-up results.

RESULTSIn 29 untreated patients, 25 T(2) to T(4) tumors were all FDG avid and 4 T(1) cases showed nothing abnormal at the primary site. In 24 patients performed curative operation 40 resected enlarged lymph nodes beyond 1 cm were diagnosed correctly by FDG-PET. FDG-PET revealed distant metastases in 5 patients and corrected them from curative surgery candidates to late stage. In 28 treated patients FDG-PET confirmed 22 cases with recurrence or metastasis.

CONCLUSIONSFDG-PET has limited value in confirming T stage in carcinoma of cardia or fundus of stomach. It showed potential in N and M staging and predicting treatment response.

OBJECTIVETo compare the outcomes of hand-assisted laparoscopic liver surgery (HALS) and pure laparoscopic liver surgery (PLS).

METHODSThe clinical data were analyzed for 64 patients undergoing major hepatectomy with HALH (23 cases) and PLS (41 cases) between January, 2010 and December, 2012.

RESULTSThe general data of the two groups were comparable. Compared with PLS, HALS was associated with a significantly shorter operative time (240 vs 191 min), less intraoperative blood loss (430 vs 220 ml, P<0.05), and a lower cost (P<0.05). There was no significant difference between the two groups in postoperative hospital stay, complication rates or recurrence rate of hepatocellular carcinoma.

CONCLUSIONHALS is safe for major liver resection with such advantages over PLS as causing less trauma and a lower cost.

OBJECTIVETo assess the value of carbon-11 choline (CH) positron emission tomography (PET) in patients with pulmonary nodules.

METHODSFrom September 2002 to December 2004, 39 patients with pulmonary nodules were imaged with CH-PET. CH-PET data was analyzed by visual method and semiquantitative method. When pulmonary nodules with abnormal CH uptake appeared in PET scans confirmed by visual method, their maximum and mean standard uptake value (SUVmax and SUVmean) were measured using semiquantitative method. Diagnoses were confirmed by surgery or biopsy and follow-up survey.

RESULTSTwenty-four cancerous and 3 inflammatory nodules and 1 bronchogenic cyst were detected by CH-PET and were diagnosed malignant with visual method. Three bronchial alveolar carcinoma, 2 metastatic tumor from kidney and colon, 3 fibrous nodules, 1 cryptococcosis, 1 hamartoma and 1 sclerosing hemangioma showed nothing abnormal in PET scans. For identification of pulmonary nodules with CH-PET, the sensitivity was 89% (24/29), the specificity was 60% (6/10), and the accuracy was 77% (30/39). There were differences in SUV between 8 squamous cell carcinomas and 9 adenocarcinomas (Z = -2.937, -2.887, P < 0.01). In diagnosing 70 resected enlarged lymph nodes beyond 1 cm in 17 lung cancer patients, CH-PET had the sensitivity of 86% (25/29), the specificity of 90% (37/41), and the accuracy of 89% (62/70). CH-PET confirmed 7 distant metastases in 25 lung cancer patients. In 5 cases suspected brain metastases CH-PET identified 2 cases positive correctly.

CONCLUSIONSCH-PET can confirm malignant pulmonary nodules, but still there were false positive and false negative cases. CH-PET can evaluate N stage effectively in patients with lung cancer. CH-PET can depict brain metastases accurately.

Cutis marmorata telangiectatica congenita (CMTC) is a congenital capillary malformation, the main clinical features are congenital persistent marbled skin, venous ectasia, telangiectasia, occasional ulcers and skin atrophy. The skin lesions are usually limited to one side of the body and do not exceed the midline. In addition to skin lesions, CMTC can be associated with other symptoms, such as bilateral limb asymmetry, glaucoma, seizures and developmental delay. In March 2019, a 10-day-old female patient with CMTC was admitted to the Department of Dermatology, Beijing Children’s Hospital, Capital Medical University. The patient had reticular and dendritic erythema on the right face, upper limb, trunk, and lower limb, especially on the lower limb. Mucopolysaccharide polysulfate cream was applied topically for more than 1 year. Later, laser treatment was performed on the obvious skin lesions on the right lower limb, and the skin lesions recovered well. The authors reported the diagnosis, treatment and follow-up process of the child in detail, and reviewed the relevant literature to further strengthen the understanding of CMTC and provide relevant experience for the diagnosis and treatment of the disease.

Objective To explore the effects of two different methods on the blood glucose variability (BGV) of patients with traumatic brain injury (TBI) who had performed the surgery.Methods A total of 100 patients with TBI after the surgery, who were admitted at intensive care unit ( ICU) from June 2013 to July 2014, were randomly assigned to the observation group ( n=50) and the control group ( n=50) . Patients in the control group received the routine treatment to adjust the BVG. Patients in the observation group received the modified Leuven′s adjustment processes. Blood glucose was continuously monitored in 5 days and all the data include mean blood glucose, incidence of hypoglycemia (level of blood glucose≤3.2 mmol/L), blood glucose standard deviation (SD), mean amplitude of glycemic excursions (MAGE) and glucose lability index (GLI) were performed statistical analysis. Results Mean blood glucose was stable in 5 days after operation in two groups (P>0.05). The blood glucose SD, MAGE and GLI in the observation group among the first 2 days [1st day:(4.7±1.2), (0.86±0.41), (255.9±213.7);2nd day:(4.0±1.7), (0.63±0.38), (202.7±163.5)] was higher than the control group [1st day:(1.1±0.68), (0.51±0.25), (112.7±92.8); 2nd day: (1.2±0.44), (0.41±0.17), (93.1±72.7)], and the difference was statistically significant (P<0.05). In the last 3 days, these data between two groups all fallen and the difference was insignificant ( P>0. 05 ) . The incidence of hypoglycemia in the observation group was lower than that of the control group in the 1st day ( P<0.05) . In the last 4 days, the data in two groups fell (P>0.05).Conclusions The modified Leuven′s adjustment processes has characteristics of early adjustment, accessible and operate simply. It is better than the routine adjustment processes in the BGV control at the early stage.

Thrombotic thrombocytopenic purpura (TTP) is an acute, potentially life-threatening thrombotic microangiopathies (TMA). TTP has mainly been diagnosed by clinical findings, such as thrombocytopenia and microangiopathic haemolytic anemia. In addition, the reduced activity of von Willebrand factor-cleaving metalloproteinase ADAMTS13 below 10% has been accepted internationally as a diagnostic criterion for TTP. In clinic, the accurate diagnosis and early initiation of therapy can significantly improve the survival rate of patients. Therapy should be focused on increasing ADAMTS13 activity and eliminating or inhibiting ADAMTS13 antibody by the infusion or exchange of therapeutic plasma and corticosteroids. Both the administration of recombinant ADAMTS13 and reducing the release of human neutrophil peptides (HNPs) would be novel promising strategies for the prevention of platelet-vWFinteraction. This review briefly summarizes the recent advances in terms of pathogenesis, diagnosis and treatment of TTP.
