AIM To determine diagnostic performance of magnetic resonance arthrography(MRA) in evaluating rotator cuff tears(RCTs) using Snyder's classification for *** One hundred and twenty-six patients(64 males, 62 females; median age 55 years) underwent shoulder MRA and arthroscopy, which represented our reference standard. Surgical arthroscopic reports were reviewed and the reported Snyder's classification was recorded. MRA examinations were evaluated by two independent radiologists(14 and 5 years' experience) using Snyder's classification system, blinded to arthroscopy. Agreement between arthroscopy and MRA on partial-and fullthickness tears was calculated, first regardless of their extent. Then, analysis took into account also the extent of the tear. Interobserver agreement was also calculated the quadratically-weighted Cohen kappa *** On arthroscopy, 71/126 patients(56%) had a fullthickness RCT. The remaining 55/126 patients(44%) had a partial-thickness RCT. Regardless of tear extent, out of 71 patients with arthroscopically-confirmed fullthickness RCTs, 66(93%) were correctly scored by both readers. All 55 patients with arthroscopic diagnosis of partial-thickness RCT were correctly assigned as having a partial-thickness RCT at MRA by both readers. Interobserver reproducibility analysis showed total agreement between the two readers in distinguishing partial-thickness from full-thickness RCTs, regardless of tear extent(k = 1.000). With regard to tear extent, in patients in whom a complete tear was correctly diagnosed, correct tear extent was detected in 61/66 cases(92%); in the remaining 5/66 cases(8%), tear extent was underestimated. Agreement was k = 0.955. Interobserver agreement was total(k = 1.000).CONCLUSION MRA shows high diagnostic accuracy and reproducibility in evaluating RCTs using the Snyder's classification for reporting. Snyder's classification may be adopted for routine reporting of MRA.

Peliosis hepatis is a rare condition characterized by dilatation of hepatic sinusoids and blood-filled spaces in the liver mainly observed in subjects exposed to toxic substances or estrogens, which is frequently asymptomatic. Non-cirrhotic idiopathic portal hypertension （NCIPH） is also a vascular disease of the liver rarely observed in European countries, which is usually diagnosed only when the hemorrhagic complications of portal hypertension occur. We report a case of NCIPH in a young Caucasian male who was diagnosed with liver peliosis, showing ultrasonographic and endoscopic signs of portal hypertension four years after. A second biopsy was diagnostic for NCIPH. Even if the pathogenesis remains obscure, peliosis hepatis can be considered as an early sign of vascular disease of the liver, which may progress to more definite conditions.

Formation of colonic diverticula, via herniation of the colonic wall, is responsible for the development of diverticulosis. When diverticulosis becomes symptomatic, it becomes diverticular disease. diverticular disease is common in Western and industrialized countries, and it is associated with numerous abdominal symptoms (including pain, bloating, nausea, diarrhea, and constipation). Standard medical therapies with antibiotics are currently recommended for patients affected by diverticular disease. However, changing concepts on the pathophysiology of the disease suggest that diverticular disease may share many of the hallmarks of inflammatory bowel diseases. On this basis, the addition of therapies using mesalazine and probiotics may enhance treatment eff icacy by shortening the course of the disease and preventing recurrences.

【Objective】To evaluate the roles of 80A→G polymorphism of RFC-1 gene encoding the reduced folate carrier protein and 677C→T polymorphism of 5,10-methylenetetrahydrofolate reductase gene(MTHFR)in neural tube defects(NTD)risk in Ukrainian population.【Methods】The folate status,homocysteine levels and genotypes were assessed in 42 mothers of fetuses with spina bifida,anencephaly and encephalocele with the age of 19-40 *** folate and plasma homocysteine levels were estimated using chemiluminescence *** was isolated from peripheral leukocytes obtained from blood using standard *** presence of the RFC-1 80A→G polymorphism was investigated using polymerase chain reaction(PCR).Real time PCR was used to detect the presence of the 677C→T mutation in the MTHFR gene.【Results】Genotype frequencies for RFC-1 80A→G in NTD group were:homozygous wild type in 9(21.4%),heterozygous type in16(38.1%)women;17(40.5%)women surveyed were found homozygous for the mutant allele genotype of RFC-1(GG).Homozygous for the indicated mutation was found in 57.1%of women with fetal anencephaly in the past history and 29.6%of women with spina bifida *** frequency in this group of women for allele A was 40.5%(34),for allele G was 59.5%(50).Among women with 80A/A genotype of RFC-1 gene reduced levels of serum folic acid were noticed only in 6(35.5%),but hyperhomocysteinemia was found in 10(58.8%)women.【Conclusion】80G→A polymorphism of RFC-1 gene is a potential genetic factor in the formation of fetus NTD in women of South Ukraine.

目的回顾性分析比较CT与US引导下肺部周围病灶和胸膜病灶穿刺活检的结果。材料与方法本研究获得了伦理审查委员会的批准,并免除病人的知情同意书。从2000年1月—2011年8月,两单位共实施了711例胸部穿刺活检术,其中273例病人的273个病灶[115例男性,158例女性,平均年龄(65±11)岁;86个胸膜病灶,187个肺部周围病灶]起源于胸膜,或位于肺部周围与胸膜有一小部分连接。这些病灶一部分行CT引导穿刺活检[170例病人,平均年龄(64±12)岁,55个胸膜病灶,115个肺部周围病灶],其余部分行US引导穿刺活检[103例病人,平均年龄(67±10)岁,31个胸膜病灶,72个肺部周围病灶],两组均使用18G改良Menghini穿刺活检针。记录穿刺时间、穿刺后气胸、出血以及组织样本量是否足够。通过Fisher精确检验、对数秩检验、Mann-WhitneyU检验对数据进行统计分析。结果两组病人的年龄(P=0.741)、性别(P=0.900)、病灶大小(P=0.206)及病灶部位(P=0.788)间的差异均无统计学意义。CT引导穿刺活检平均时间为556s(25%四分位数为408s;75%四分位数为704s);US引导穿刺活检平均时间为321s(25%四分位数为157s;75%四分位数为485s)(P<0.001)。CT、US引导下穿刺活检气胸发生率分别为14.7%(25/170)和5.8%(6/103)(P=0.025),出血发生率分别为1.2%(2/170)和1.0%(1/103)(P=0.875),技术成功率分别为96.5%(164/170)和97.1%(100/103)(P=0.999)。结论对于胸膜或肺部周围病灶,US引导下穿刺活检与CT引导相比较,虽然取样的准确性相似,但前者具有穿刺时间更短,穿刺后气胸发生率相对较低及无需接触电离辐射等优势。
