OBJECTIVETo investigate the diagnostic value of MRI in radial head fracture with forearm interosseous membrane injuries.

METHODSFrom December 2011 to December 2012,26 patients with fractures of capitulum radial in our hospital were collected. There were 15 males and 11 females, ranging in age from 21 to 53 years old,with an average of 37.6 years old. All the patients visited hospital within 72 hours after injuries. X-ray radiography of full ulnar radial length in injured side, CT in injured side (three-dimensional reconstruction if necessary) and MRI (including the elbow and wrist joints) were performed within a week after the injury. The MRI manifestations of the forearm interosseous membrane (with or without damage, the injured location and the injury degree ) and the fractures degree of radial head were observed and compared for the relativity.

RESULTSRadial head fracture from Mason type I to III was associated with the forearm interosseous membrane injury. Radial head fracture degree was positive correlated with forearm interosseous membrane injury degree (P < 0.05).

CONCLUSIONRadial head fracture with suspicious forearm interosseous membrane injury is necessary to take MRI for checking for any interosseous membrane injury and injury degree, then choose the right treatment for radial capitulum fracture, only in this way can be helpful for the functional recovery of elbow and forearm.

Objective To semiquantify salivary gland damage after 131I treatment in patients post thyroidectomy using salivary gland scintigraphy. Methods Fifty-six patients underwent salivary gland scintigraphy 6 months after 131I ablation therapy following thyroidectomy, including 21 with both baseline (before 131I treatment) and follow-up (6 months after the 1st 131I treatment) imaging. Salivary gland function was quantified by uptake ratios at 4 minutes (UR4) and 15 minutes (UR15), and excretory index at maximum secretion (MS), time duration from stimulation to minimum count (Tmin ). Paired t test was used for the 21 patients with both baseline and follow-up imaging. All the studies were divided into four groups: before 131I therapy, after 1st therapy, after 2nd therapy, and after 3rd or more times of therapy. Group differences were evaluated by the one-way analysis of variance (ANOVA)/Kruskal-Wallis test. Spearman test was used to analyze the correlation between the parameters and times of therapy. Results After the 1st 131I therapy, UR15 for the left and right parotid glands were 16% and 14% lower than the baseline, respectively (t=2.188, 3.322, both P<0.05). All the other parameters were not significantly different from those of baseline (t: -0.952 to 2.039, all P>0.05). Among the four groups, significantly different parameters for both parotid glands were found: UR4, UR15, MS for the left parotid of the four groups were 1.76±0.29, 2.60±0.38, (72.8±24.2)%; 1.55±0.34, 2.15±0.51, (64.4±21.6)%; 1.55±0.40, 2.02±0.68, (57.2±34.2)%; 1.45±0.33, 1.69±0.46, (30.6±36.9)%; respectively (F values for UR4 and UR15 were 7.018, 3.112 and H value for MS was 12.240, all P<0.05). UR4, UR15, MS for the right parotid were 1.81±0.33, 2.57±0.51, (69.1±18.5)%; 1.61±0.38, 2.19±0.59, (64.2±25.0)%; 1.60±0.42, 2.00±0.62, (53.2±41.7)%; 1.48±0.38, 1.63±0.29, (26.1±45.9)%, respectively (F=13.393,10.194,H=26.569,all P<0.05). However, no statistical differences were P>0.05). According to pair-pair comparison, only the degree of reduction of UR15 for parotid glands was significantly different between the 1st and 2nd therapy (P<0.05). UR4, UR15, MS for bilateral parotid glands reduced significantly after 3 or more times of therapy (all P<0.05).The parametres UR4, UR15, MS were correlated with times of 131I therapy (r:-0.296 to -0.566, all P<0.05). Conclusions Salivary uptake function is impaired slightly after the 1st radioiodine therapy. After several times of therapy, both parotid uptake and excretion functions are impaired. Submandibular functions are not affected even after repeated 131I therapy.

OBJECTIVETo investigate surgical procedure and clinical effects for the treatment of patellofemoral osteoarthritis (PFOA) with arthroscopic patelloplasty and circumpatellar denervation.

METHODSTotally 156 patients with PFOA (62 males and 94 females; aged from 45 to 61 years old with an average of 52) were treated from September 2011 and March 2013. The clinical manifestations included recurrent swelling and pains on knee-joint,and aggravated pains upon going up/down-stairs, squatting-down, or standing-up. PFOAs were treated with arthroscopic patelloplasty and circumpatellar denervation. The therapeutic effects before and after surgery were evaluated by Lysholm scores and Kujala scores. The therapeutic effects were graded by classification of cartilage injury degrees.

RESULTSTotally 149 cases were successfully followed up for 14.8 months. The incisions were healed well and no complication were occurred. Lysholm score was improved from 73.29 preoperatively to 80.93 postoperatively and average Kajala score from 68.34 preoperatively to 76.48 after surgery. This procedure was highly effective for patients with I - III degree cartilage injury, while not for patients with IV degree cartilage injury.

CONCLUSIONFor PFOA patients, arthroscopic patelloplasty and circumpatellar denervation is effective for significantly relieving anterior knee pains, improving knee-joint functions and quality of life, and deferring arthritic procession.

OBJECTIVETo investigate the clinicopathological features, diagnosis, treatment and prognosis of primary clear cell carcinoma of the liver (PCCCL).

METHODSThe clinicopathological data of 24 cases with pathologically proven PCCCL in the First Affiliated Hospital of Guangxi Medical University from May 1996 to December 2003 were collected and analyzed.

RESULTSThere were 21 males and 3 females in this group, with an average age of 46 years (range: 30 approximately 78 years). HBV infection was detected in 83.3%, and AFP expression was found in 75.0% of them. Of the 24 cases, 28 tumors were found with an average size of (6.64 +/- 5.54) cm. Liver cirrhosis was found in 75.0% of the patients. Macroscopic and microscopic tumor thrombi were found in 20.8% and 29.2%, respectively. Lymph node metastasis was found in 4.2% of the patents. The 1-, 3-, and 5-year overall survival rates of the 24 cases were 75.0%, 41.7% and 27.8%, respectively, with a median survival time of 29 months.

CONCLUSIONThe clinical characteristics of primary clear cell carcinoma of the liver are similar to that of common hepatocellular carcinoma. It is difficult to be diagnosed preoperatively and final diagnosis depends on pathological examination. Surgical resection is an effective way to achieve favorable treatment outcome and even long-term survival.
