Objective To evaluate the MR findings of normal and abnormal collateral ligament. Methods The MR findings of 56 normal and 36 surgically confirmed injured collateral ligaments were retrospectively reviewed and compared. Results The normal tibial and fibular collateral ligaments were hypointense string on both T 1 and T 2 coronal MR images, with an average length of 6.8 cm for tibial collateral ligament and 5.7 cm for fibular collateral ligament. 36 collateral ligaments were injured, including 18 tibial and 12 fibular collateral ligaments. Three cases (6 ligaments) had both tibial and fibularcollateral ligaments injuries. The injury of collateral ligament was classified as: Grade I (18 ligaments), Grade Ⅱ (11 ligaments), and Grade Ⅲ (7 ligaments). The complications of anterior cruciate ligament sprains (13 cases), posterior cruciate ligament sprains (9 cases), meniscal tears (12 cases), bony contusion and fracture (7 cases), and joint effusion (20 cases) were found in 25 patients(78%). Conclusion Coronal MR imaging can clearly demonstrate the structure of the knee collateral ligaments, accurately diagnose and classify the ligament injury, and correctly detect the complications. MRI should be used as a routine examining method for knee trauma.

INTRODUCTIONErythroderma is a generalised inflammatory reaction of the skin secondary to a variety of causes. This retrospective study aims to characterise the features of erythroderma and identify the associated causes of this condition in our population.

MATERIALS AND METHODSWe reviewed the clinical, laboratory, histological and other disease-specific investigations of 225 inpatients and outpatients with erythroderma over a 7.5-year period between January 2005 and June 2012.

RESULTSThe most common causative factors were underlying dermatoses (68.9%), idiopathic causes (14.2%), drug reactions (10.7%), and malignancies (4.0%). When drugs and underlying dermatoses were excluded, malignancy-associated cases constituted 19.6% of the cases. Fifty-five percent of malignancies were solid-organ malignancies, which is much higher than those previously reported (0.0% to 25%). Endogenous eczema was the most common dermatoses (69.0%), while traditional medications (20.8%) and anti-tuberculous medications (16.7%) were commonly implicated drugs. In patients with cutaneous T-cell lymphoma (CTCL), skin biopsy was suggestive or diagnostic in all cases. A total of 52.4% of patients with drug-related erythroderma had eosinophilia on skin biopsy. Electrolyte abnormalities and renal impairment were seen in 26.2% and 16.9% of patients respectively. Relapse rate at 1-year was 17.8%, with no associated mortality.

CONCLUSIONOur study highlights the significant proportion of malignancy-related erythroderma in those whom common underlying causes such as dermatoses and drugs have been excluded. In cases of drug-related erythroderma, traditional medications and antituberculous medications are common causes in our population. Renal impairment and electrolyte abnormalities are commonly seen and should be monitored in patients with erythroderma.

Objective To evaluate the diagnostic value of ~(99)Tc~m-methoxyisobutylisonitrile (MIBI) SPECT scintigraphy combined Iocalizable CT in the localization of ectopic parathyroid glands in hyperparathyroidism.Methods Retrospective data of surgery,pathology and imaging were collected from 28 patients with hyperfunctioning ectopic parathyroid glands.All cases underwent CT studies.Twenty-five patients had ~(99)Tc~m-MIBI planar imaging first:SPECT scintigraphy combined localizable CT was performed for the patients with abnormal radionuclide foci immediately.The fusion images obtained after reconstruction showed the exact location of the ectopic foci.Operative histopathologic results were regarded as "gold standards".Presuming 4 parathyroid glands as normal findings,findings confirmed by operation and pathology were regarded as positive,otherwise negative.The results of CT and radionuclide imaging were compared by X~2-test of four-foId table.Results Twenty-eight ectopic parathyroid glands were found in 28 patients,all pathologically confirmed as adenomss.CT found 22 foci,of which 17 were true positive,5 false positive,11 false negative,and 79 true negative.~(99)Tc~m-MIBI SPECT scintigraphy combined localizable CT found 23 foci,no false positive,2 false negative,and 75 true negative.The results showed that the sensitivities were 61% (17/28),92%(23/25),specificities 94%(79/84),100%(75/75),accuracies 86%(96/112),98% (98/100),positive predictive values 77%(17/22),100%(23/23),and negative predictive values 88% (79190),97%(75/77),respectively,for CT and radionuclide imaging.~(99)Tc~m-MIBI SPECT scintigraphy combined localizable CT was therefore significantly higher than CT in sensitivity(X~2=6.98,P＜0.01),specificity (X~2=4.61,P＜0.05),accuracy (X~2=10.30,P＜0.01),positive predictive value(X~2=5.88,P＜0.05) and negative predictive value (X~2=5.36,P＜0.05).Conclusion ~(99)Tc~m-MIBI SPECT scintigraphy combined localizable CT is superior to CT alone in the localization of ectopic parathyroid glands in hyperparathyroidism,but false negative can be found in some patients.

Objective : To identify spatio-temporal distribution patterns of mumps in Zhejiang Province from 2008 to 2019, so as to provide insights into precise control of mumps. Methods : The epidemiological data pertaining to mumps in Zhejiang Province from 2008 to 2019 were collected from the China Information System for Disease Control and Prevention. The time- and region-specific incidence of mumps was descriptively analyzed, and the spatio-temporal clustering characteristics of mumps incidence were identified using global and local spatial autocorrelation analyses and spatio-temporal scan analysis. Results : A total of 167 196 cases of mumps were reported in Zhejiang Province from 2008 to 2019, and the incidence of mumps reduced from 56.08/105 in 2008 to 11.35/105 in 2019, with a reduction of 79.76%. There was no remarkable mumps seasonality since 2017; however, spatial autocorrelation was seen in mumps incidence in 2008, 2011 and 2012, respectively ( Moran's I coefficient=0.16, 0.18, 0.16; all P<0.05 ). Spatio-temporal scan analysis identified five spatio-temporal clusters of mumps incidence in 2008, 2011 and 2012, and the most likely spatio-temporal cluster was mainly concentrated in Cangnan County of Wenzhou City, covering 17 counties clustered in the time frame from 15 January 2008 to 28 February 2009, while the other four clusters were concentrated in Pinghu City of Jiaxing City, Kaihua County of Quzhou City, Fuyang District of Hangzhou City and Zhuji City of Shaoxing City, clustered in the time frame from 15 January 2008 to 30 June 2012. Conclusion The incidence of mumps appeared a tendency towards a reduction in Zhejiang Province from 2008 to 2019, and rebounded in some regions. No remarkable mumps seasonality was seen since 2017. The spatio-temporal clusters of mumps incidence were concentrated in Wenzhou and Jiaxing cities of Zhejiang Province in 2008, 2011 and 2012; however, no spatial cluster was identified since 2012.
