Primary hemangiopericytoma of the rib is extremely rare and only a few cases have been reported. A 62-yr-old man presented with an aching chest pain and dyspnea. Thoracic computed tomography revealed a homogenous mass expanding the right seventh rib. A diagnosis of hemangiopericytoma was established by percutaneous needle biopsy. Preoperative embolization of the feeding vessels of the tumor was performed in order to prevent perioperative bleeding. There was no significant bleeding during the surgery, where complete resection of the tumor with 7th to 9th ribs with a surgical margin of 5 cm was performed. Postoperative course was uneventful and there has been no recurrence for thirteen months. To our knowledge, there has been no report to apply a preoperative embolization of a primary hemangiopericytoma of the rib.  相似文献

The present study was designed to evaluate the significance of echocardiography versus cardiac troponin I levels in early detection of anthracycline dependent cardiotoxicity in acute lymphoblastic leukemia (ALL) patients. A total of 276 pediatric ALL patients were included in the study prospectively along 3 phases of data collection lasted from 2002 to 2009; including phase I (March 2002 to February 2003; n = 25; 53.3% females), phase II (September 2003 to April 2004; n = 35; 57.1% females), and phase III (January 2005 to June 2009; n = 216; 52.7% females) with respect to cumulative anthracycline doses applied. Anthracycline was administered in accordance with berlin-Franfurt-Munich (BFM)-2000 protocol in doses of 30 to 350 mg/m(2) (in the first phase) and 30 to 240 mg/m(2) (in the following phases). Evaluation of cardiotoxicity was performed via echocardiography and measurement of cardiac troponin I levels. Patients in each phase were homogenous in terms of gender and age. Diastolic dysfunction determined via reduction E/A ratio below the cutoff value was demonstrated to deteriorate earlier than systolic functions and alteration in cardiac enzymes. Being similar between dose groups, cTnI levels were shown to rise in the presence of congestive heart failure. In conclusion, anthracycline cardiotoxicity appears to be detected in an earlier stage by using diastolic parameters compared to systolic parameters and cardiac enzymes.  相似文献

Objective

The purpose of our study was to evaluate the relationship between endometrial polyps and obesity, diabetes mellitus (DM) and hypertension (HT).

Materials and methods

202 patients who applied to our gynecology clinic with complaints of infertility, recurrent pregnancy loss and abnormal uterine bleeding, diagnosed to have endometrial polyps by hysteroscopy, were compared with 79 patients without polyps, retrospectively. The relationships between risk factors and presence of a polyp and polyp size were analyzed.

Results

The mean age of cases with endometrial polyps was significantly greater than the controls. The mean body mass index (BMI) of the cases with polyps was also significantly greater than the controls. There was no significant difference between groups with respect to prevalence of DM or HT.

Conclusion

This study suggests that obesity is an independent risk factor in the development of endometrial polyps. Clinicians should be aware in terms of endometrial polyps in the assessment of patients with BMI ≥30. There was no relationship between HT or DM with presence of polyps.  相似文献

Porous interconnected hydroxyapatite (HA) and HA/tricalcium phosphate (TCP) (60/40) ceramics are promising materials for hard tissue repair. However, the mechanical properties of these materials have not been accurately determined under weight-bearing conditions. In this study, newly developed HA and HA/TCP (60/40) ceramics were used with intramedullary fixation in segmental bone defects of rabbits. Early radiological, histological, densitometric and biomechanical changes were evaluated. The mean radiological grade of healing and bonding to bone was higher in HA/TCP (60/40) ceramics than that of pure HA ceramics but the difference was not statistically significant. The densities of both implanted ceramics improved with time, supported by the histological evaluation of bone matrix ingrowth into ceramic pores, whereas the densities at the bone–ceramic interface decreased gradually. Flexural resonant frequencies and three-point bending strength increased, revealing an increase in mechanical stability during this early critical time interval where implant and/or bone–implant interface failures occur frequently. It can be concluded that both HA and HA/TCP (60/40) ceramics have a limited application in the treatment of load-bearing segmental bone defects but did not fail at the early stages of implantation.  相似文献

Introduction: Burn healing is a complicated process and very few treatments can positively alter its effects. The aim of this study was to investigate the effects Salvia miltiorrhiza (SM -Danshen), a traditional Chinese medicine, on burn wound healing.

Material and methods: Twenty rats were included in this study and divided into two groups. 3?×?2?cm wide burn areas were created in the dorsal skin of all the animals with thermal contact. Intraoral 1?ml/day saline and 1?g/kg/day SM were given in control and experiment groups, respectively. Fourteen days following the burn injury burn zones were evaluated with indocyanine green-SPY imaging device, and multiple samples were collected for histopathological evaluation. Standard photographs were taken for the evaluation of necrotic skin areas.

Results: Neovascularization was increased in the SM group when compared with the control group (p?=?0.0406). SPY studies revealed a meaningful increase in the tissue perfusion in the SM group (p?=?0.0286). The average amount of necrotic area in the control and experiment group on the postoperative 14th day was 71.6% (±16.51) and 42.5% (±10.64) respectively (p?=?0.0002).

Conclusion: Our study shows that SM can decrease the amount of necrosis in burn wounds by increasing tissue perfusion and neovascularization.  相似文献

The present study aimed to evaluate the effectiveness of 2.5 mg/kg/day cyclosporin (CsA) treatment in patients with severe chronic idiopathic urticaria (CIU) and the impact of CsA treatment on several cytokines involved in the etiopathogenesis of CIU. Twenty-seven CIU patients and 24 healthy control subjects were included in the study. The autologous serum skin test (ASST) for autoantibodies and urticaria activity scoring (UAS) were measured for the evaluation of the clinical severity and the response to therapy, and the serum levels of interleukin (IL)-6, IL-8, IL-2 receptor, IL-1beta, tumor necrosis factor (TNF)-alpha and IL-5 were measured. The mean UAS score was 32.07 +/- 7.05 and 6.22 +/- 3.84 before and after CsA treatment, respectively. The serum IL-2 receptor, TNF-alpha and IL-5 levels of patients before CsA treatment were statistically higher than those of the control group (P = 0.001), and after 4 weeks of CsA therapy the mean IL-2R, TNF-alpha and IL-5 levels were significantly decreased. The data from this study demonstrate that CsA therapy is efficient and safe for CIU patients. Increase in clinical efficacy and marked decreases in serum cytokine levels suggest that inhibition of cytokine generation is involved in the action of the drug in this clinical setting.  相似文献

Tangier disease (TD) (OMIM#205400) is a rare cause of inherited metabolic neuropathies characterized by marked deficiency of high‐density lipoproteins and accumulation of cholesterol esters in various tissue resulting from reverse cholesterol transport deficiency. We report a case of a patient with TD with multifocal demyelinating neuropathy with conduction block who presents with winging scapula, tongue, and asymmetric extremity weakness. We also present a review of all studies published from 1960 to 2017 regarding peripheral neuropathy in TD. Our search identified 54 patients with TD with peripheral neuropathy. Syringomyelia‐like neuropathy subtype (52.4%) was more frequent than multifocal sensorial and motor neuropathy subtype (26.2%), focal neuropathy subtype (19.1%), and distal symmetric polyneuropathy subtype (2.4%). Splenomegaly was the most common (40.7%) clinical manifestation in these patients. The pattern of electrodiagnostic abnormalities are: (1) demyelinating abnormalities were more predominant in the upper extremities than in the lower extremities and (2) slowing of motor nerve conduction was more prominent in the intermediate segment than in distal nerve segments. The sural‐sparing pattern was present in 34.6% and conduction block was present in 11.5% of the patients. Our literature review and our case showed the clinical spectrum of TD neuropathy is quite wide and that it should be considered in the differential diagnosis of non‐uniform demyelinating neuropathies.  相似文献

This study evaluates the associations among the symptoms of anxiety, depression, and disruptive behavioral disorders (DBD) in the context of their relationships with reactive–proactive aggression and anxiety sensitivity in children with attention-deficit/hyperactivity disorder (ADHD). The sample consisted of 342 treatment-naive children with ADHD. The severity of ADHD and DBD symptoms were assessed via parent- and teacher-rated inventories. Anxiety sensitivity, reactive–proactive aggression and severity of anxiety and depression symptoms of children were evaluated by self-report inventories. According to structural equation modeling, depression and anxiety scores had a relation with the DBD scores through reactive–proactive aggression. Results also showed a negative relation of the total scores of anxiety sensitivity on DBD scores, while conduct disorder scores had a positive relation with anxiety scores. This study suggests that examining the relations of reactive–proactive aggression and anxiety sensitivity with internalizing and externalizing disorders could be useful for understanding the link among these disorders in ADHD.  相似文献

OBJECTIVE: The purpose of this study was to compare the effects of tube drainage versus a single dose of methylprednisolone (MP) on maximal mouth opening, facial swelling, and pain after third molar surgery. STUDY DESIGN: Twenty-two patients requiring extraction of bilaterally impacted mandibular third molars were selected. Each patient had 2 operations. In the first operation, a drainage tube was inserted into the buccal fold after the suture procedure and left there for 3 days. In the second operation 1 month after the first surgery, 1.5 mg/kg intravenous methylprednisolone was administered 1 hour before the surgery. The patients were evaluated by the same person for maximal mouth opening, facial swelling, and pain in the immediate preoperative time point and on the second, fifth, and seventh days after surgery. RESULTS: There was a statistically significant difference in mouth opening on fifth and seventh days but none in facial swelling and pain between MP group and drain group. CONCLUSION: We conclude that the use of a drain or methylprednisolone is useful in reducing postoperative discomfort after third molar surgery.  相似文献
