LONG‐TERM OUTCOME OF ENDOSCOPIC BALLOON DILATION IN OBSTRUCTIVE GASTROINTESTINAL CROHN's DISEASE

Background: Gastrointestinal strictures are the most often and serious complication in Crohn's disease. Because of the frequent postoperative recurrence in Crohn's disease, endoscopic therapy of gastrointestinal stricture is one of the best therapeutic options. Method: The present study sets out the results from a prospective study of endoscopic dilation therapy on 48 Crohn's disease patients with severe gastrointestinal stenoses. All patients who could not undergo endoscopic balloon dilation therapy (EBD) were operated on. Results: Long‐term success was attained in 32 of the 48 patients; cumulative avoidance of surgery after EBD was 86% at one year and 71% at three. Second, the most hazardous factor was recurrent inflammation causing restenosis. Patients who had strictures with oral luminal dilatation and patients with frequent recurrence had a tendency to be operated on. As a complication, perforation occurred in two cases (3.3%). Conclusions: EBD therapy for Crohn's stricture in the gastrointestinal tract is recommended before surgical intervention.     

间期荧光原位杂交检测核心结合因子相关急性白血病的初步研究

目的应用间期荧光原位杂交技术(I-FISH)检测初诊急性白血病患者中核心结合因子(CBF)受累的染色体异常情况并对治疗后患者的微小残留病(MRD)进行监测,同时对I-FISH与常规染色体G显带的灵敏度进行比较。方法在骨髓形态学初筛的基础上,应用常规染色体G显带技术对15例急性髓系白血病(AML)进行核型分析,应用I-FISH对患者可能受累的CBF相关靶基因进行检测,其中7例患者治疗后进行了MRD监测。结果(1)正常对照组中,CYTOCELL公司提供的3种探针(AML1/ETO易位探针、MYH11基因断裂点双色探针和ETV6/AML1易位探针)的正常分界值分别为4.13%、1.95%和2.12%。(2)常规染色体G显带分析,15例患者中有6例伴有潜在累及CBF基因的染色体异常,其中8例AML-M2中5例伴t(8;21),2例AML-M4EO中1例伴inv(16),5例儿童B系急性淋巴细胞白血病(B-ALL)未检出相应的异常。I-FISH检测15例患者发现有12例累及CBF基因,其中8例AML-M2患者均为AML1/ETO融合基因(+),2例AML-M4EO病人CBFβ/MYH11融合基因均为(+),5例儿童B-ALL中2例ETV6/AML融合基因(+)。(3)3例AML-M2患者中2例MRD阳性;2例M4E0患者治疗后MRD监测结果均阴性;2例B-ALL患者1例阴性,1例阳性。结论I-FISH较常规染色体G显带技术能够更灵敏地检测出累及CBF的急性白血病,在初诊时联合应用这两种

Usefulness of osteoprotegerin in assessing responses to neridronate treatment in Paget's disease of bone

Osteoprotegerin (OPG) is a protein that inhibits of osteoclastogenesis. The aim this study was to evaluate the response of serum OPG levels to neridronate treatment in patients with Paget's disease of bone resistant to previous therapy. Nine patients (4 men) affected by active Paget’s disease of bone (6 polyostotic, 3 monostotic) not responsive to clodronate were studied. Serum OPG, osteocalcin, total and bone isoenzyme of alkaline phosphatase (AP and BAP, respectively), and urinary deoxypyridinoline (DPD) were measured before and 5 months after neridronate treatment (100 mg/day, i.v. for two days). A scintigraphic activity index (SAI) was also calculated before treatment. Mean baseline OPG levels were within normal values and were not significantly different 5 months after neridronate treatment. In contrast, there were significant reductions in AP (41.9%, p<0.02) and BAP (38.8%, p<0.04). Serum OPG levels correlated with DPD (r=0.925) and SAI (r=0.689). Although OPG is an important regulator of bone metabolism, in our series of already treated patients it was not a sensitive marker for diagnosing Paget's disease and for monitoring the response to pharmacological treatment, whereas AP and BAP confirmed their clinical usefulness. This preliminary study requires confirmation by a study with a larger population.     

Sleep complaints and their relation with drug treatment in patients suffering from Parkinson's disease.

The aim of this research was to quantify sleep problems in patients suffering from Parkinson's disease by means of the new Parkinson's Disease Sleep Scale (PDSS) and to correlate such problems with the possible influence of current drug treatment. A total of 70 patients (36 men and 34 women) with a diagnosis of Parkinson's disease were enrolled. Their mean age was 69.7 +/- 8.2 years, and duration of disease was 7.4 +/- 4.8 years. All patients completed the PDSS and the Unified Parkinson's Disease Rating Scale (UPDRS Parts I-IV). Drug consumption and doses were registered. The mean score on the PDSS scale was 109.23 +/- 19.75 and on the UPDRS III scale was 25.24 +/- 11.35. The lowest scores were obtained in Item 3 (sleep fragmentation): 5.53 (2.46); and in Item 8 (nocturia): 5.75 (2.91). There was a weak correlation between the PDSS and UPDRS III (cc = -0.355, P = 0.003), PDSS and UPDRS I (cc = -0.272, P = 0.02), and PDSS and UPDRS IV (cc = -0.416, P < 0.001). Motor conditions, mental state, and drug complications influence sleep quality. Although this effect was significant, it was not of a great magnitude. Dopaminergic drugs did not increase daytime sleepiness. As a whole, sleep quality in patients who took dopaminergic agonists did not differ from that of patients who took levodopa in monotherapy.     

Long-term benefit to pallidal deep brain stimulation in a case of dystonia secondary to pantothenate kinase-associated neurodegeneration.

Pantothenate kinase-associated neurodegeneration (PKAN) is a rare autosomal recessive disorder with onset in childhood and rapid progression. There is no causative and insufficient symptomatic drug therapy. Deep brain stimulation (DBS) of the internal pallidum (GPi) has been reported to improve motor function. Most case reports, however, are limited to short observational periods. The impact of DBS on the progression and life expectancy in PKAN is unknown. We present a 5-year outcome and video documentation of bilateral GPi-DBS of an adolescent patient suffering from genetically defined PKAN.     

Calciphylaxis – a topical overview

'Calciphylaxis', a calcification syndrome associated with ischaemic cutaneous necrosis, is acquired naturally in humans in disease states. It is a life and limb-threatening complication, usually observed in patients with renal disease and secondary hyperparathyroidism, but known to occur in the absence of renal or parathyroid disease. The reported mortality rate, which ranges from 60-80%, relates to wound infection, sepsis and organ failure. It is a small-vessel vasculopathy, which is estimated to occur in about 4% of haemodialysis patients. Clinically, violaceous, reticulate areas of cutaneous necrosis and eschar may be evident, particularly in the extremities. In addition to the clinical picture, a raised calcium phosphorous product, an elevated parathyroid hormone level, radiographic evidence of vessel and soft-tissue calcification and the finding of mural calcification affecting small arteries and arterioles on histopathology help to confirm the diagnosis of this entity which generally has a poor prognosis. A high index of suspicion and an active multidisciplinary management approach, with rigorous attention to wound care and prevention of sepsis, are vital in the management of these patients. In this overview, we discuss the pathophysiology, clinical features and associations, risk factors, diagnosis and management issues relating to calciphylaxis.
