Objective. Many intracranial aneurysms often have branch arteries, and it is especially important to protect them during embolization. The purpose of the present study was to evaluate the curative effect and safety of the “stilted building” technique. Methods. 25 patients with intracranial aneurysms with branch arteries that have been treated by coil embolization with the “stilted building” technique were retrospectively reviewed. Clinical follow-up was performed after endovascular treatment. Results. All 25 patients successfully underwent aneurysm embolization. During the operation, the ruptured sac and most of the body of the aneurysm were embolized using the “stilted building” technique. Immediate imaging showed that the blood flow to the branch arteries from the neck or sidewall of the aneurysm was unobstructed. The mRS scores of the 25 patients during the follow-up period were mRS 0 for twenty-one patients, mRS 1 for three patients, and mRS 6 for one patient. No aneurysms recurred among the patients who completed the follow-up. Conclusions. In an aneurysm with a branch artery, when a balloon or stent cannot be effectively used to protect the branch artery, the use of “stilted building” embolization can achieve good therapeutic effects, and the short-term follow-up results are satisfactory; the technique can effectively protect branch arteries originating from aneurysms.

Aim: To check the short-term tonometric results of SLT in the treatment of primary glaucoma at the open angle and in charge of ocular hypertonias in Togolese people. Methods: A retrospective study was carried out in an ophthalmology center. The first 130 eyes of 72 patients benefited from the SLT laser procedure. The tonometric controls work object focus on follow-up at 1, 3, and 6 months post laser treatment. Results: 130 eyes of 72 patients were collected. The average age of the patients was 49.74 years (± 17.45) and the ages vary between 10 and 85 years. The average IOP of the laser before the laser (J0) was (24.99 ± 8.41) mm Hg. The mean IOP at the post-laser control at 1 month was (18.79 ± 3.73) mm Hg. The average IOP for the post-laser control at 3 months was (18.44 ± 3.81) mm Hg. The mean IOP at the post-laser control at 6 months was (18.13 ± 3.63) mm Hg. The percentage reduction in intraocular pressure compared to IOP was pretreated from 20.2% to 1 month; 22.1% at 3 months; and 23.3% at 6 months. In 1 month, 49.2% of the eyes we treated showed a reduction in IOP of less than 20% compared to IOP pretreatment. After 3 months and 6 months, it was 55.4% higher. Also, 52.3% have a PIO reduction percentage which is greater than or equal to 20% compared to pre-treatment IOP. Discussion: Selective laser trabeculoplasty, most especially, is interesting in ocular hypertonies. Treatment of over 180 ° allows one patient out of two to have a pressure reduction that is greater than or equal to 20%. Conclusion: The SLT presents a significant advantage for our glaucomatous patients.

ABSTRACT Objective Shortwave diathermy causes increase in temperature from deep inside the body, results in upregulation of metabolism, and has analgesic effects. In this study, we explored the potential application of shortwave diathermy in the maxillofacial region by monitoring internal and external temperature changes, changes in blood flow, and resting saliva secretion under shortwave diathermy for subjects with and without dental metal restorations (MR) to confirm the safety and the limitation of shortwave diathermy for dental medicine. Materials and methods Twenty young healthy subjects were recruited (10 subjects with MR and 10 subjects without MR). Shortwave exposure was achieved with condenser-type probes placed on the bilateral mandibular angles, and the intraoral temperature was monitored. For functional analysis, unstimulated whole saliva before and after exposure was collected. The temperature and blood flow distributions of the exposed areas were then monitored by thermography and twodimensional (2D) laser Doppler flowmetry. Results Shortwave exposure for 20 minutes induced significant temperature increases in all groups (p ≤ 0.05). The subjects reported no discomfort. When subjects without MR held gold or titanium crowns in their mouths, the thermal effect by shortwave diathermy was reduced. Resting saliva upon exposure only increased significantly in metal-free subjects, and amylase concentration was also increased, but the level of the salivary stress biomarker chromogranin A was unchanged. Furthermore, thermography showed that shortwave diathermy significantly increased the surface temperature for cheek skin and the buccal mucosa; however, this increase failed to elevate surface blood flow. Conclusion Shortwave diathermy induces temperature increases in the maxillofacial region. MR did not cause excessive heating, on the contrary, reduce the thermal effect of shortwave radiation. The temperature rise maintains upregulation in salivary function, which could be utilized safely in dental medicine.

Objective: This study focused on the efficacy and safety of thalidomide for patients with thalassemia intermedia (TI) in a multicenter trial. Methods:Clinical and laboratory data of 62 patients subjected to thalidomide therapy in four centers were retrospectively analyzed. We evaluated the efficacy and safety of thalidomide in the short-term (three months) and long-term follow-up (12 and 24 months). Response to thalidomide was defined as follows: Main Responder (MaR) showing an increase in Hb level of >2.0 g/dl or removal from blood transfusion and Minor Responder (MiR) achieving elevated hemoglobin (Hb) level of 1.0-2.0 g/dl or ≥50% reduction in blood transfusion frequency. Results:The overall response rate (ORR) of 62 patients with TI was 93.5% (58/62), with MaR and MiR rates accounting for 62.9% (39/62) and 30.6% (19/62) in short-term follow-up and 66.1% (41/62) and 27.4% (17/62) in long-term follow-up, respectively. The clinical response during long-term follow-up was maintained and the Hb level remained stable during the observation period. The response was still observed in patients with dose reduction despite a slight decrease in Hb level. However, Hb decreased rapidly to the baseline level after drug discontinuation. No effect of thalidomide on spleen size in nonsplenectomized patients was evident. Minimal side-effects were documented throughout, except peripheral neurotoxicity in one patient. Nevertheless, the mean serum ferritin (SF) level was significantly increased after treatment. Conclusion: Thalidomide had significant therapeutic effects on patients with TI, and the response was sustained with acceptable short-term and long-term adverse reactions. While these preliminary results support the potential long-term efficacy and safety of thalidomide as a therapeutic agent for TI, several issues need to be addressed before its application in the clinic.

Objective – to improve treatment results of patients with ruptured brain aneurysms using follow-up cerebral digital subtraction angiography to avoid de novo or aneurismal regrow.Materials and methods. Analysis of follow-up cerebral digital subtraction angiography and treatment results of two patient (60 and 64-year-old females) with brain anterior communicated artery de novo aneurysm and regrowed aneurysm of an anterior communicated artery after microsurgical clipping.Results. Two patient underwent endovascular treatment of ruptured brain aneurysms after non follow-up cerebral digital subtraction angiography. In first case de novo aneurysm of anterior communicating artery and in second – regrowed aneurys of anterior communicating artery after surgical clipping. Both patients were discharged from the clinic in I and IV modified Rankin scale. Conclusions. Digital subtraction angiography follow-up of intracranial aneurysms treated by endovascular or microsurgical approach is important for the detection and prediction for the risk of bleeding (aneurysm recurrence and de novo aneurysm). There exist no guidelines on the frequency of monitoring and imaging modality to adopt and the monitoring is adapted on a case-by-case basis. Digital subtraction angiography is the gold standard for the evaluation of aneurysmal occlusion after coiling and microsurgical clipping and remains also necessary for evaluating other devices.

Abstract Background: Optical coherence tomography angiography (OCTA) is a principally new imaging technique that provide quantitative method to analyze choriocapillaris (CC) flow changes, while assessment of CC in vivo could be valuable in understanding the pathological mechanism of chronic central serous chorioretinopathy (CCSC) and the therapeutic effects of photodynamic therapy (PDT). In this study, we sought to quantify blood flow changes in CC of CCSC patients receiving half-dose PDT using OCTA.Methods: A total of 28 affected eyes and 24 unaffected eyes of 26 CCSC patients receiving half-dose PDT, and 40 eyes of 20 healthy gender- and age-matched subjects were retrospectively enrolled. The proportion of total areas of flow signal voids (FSV, %) in CC level of OCTA was assessed in both eyes of the CCSC patients at baseline and repeated in multiple sections at 1-week, 1-month, 3-month and 6-month intervals after PDT. In addition, CC patterns in response to PDT at early stage and their subsequent morphologic changes were qualitatively documented using OCTA. Results: For affected eyes, significant decrease in FSV was found at 6-m follow-up when compared with that at 1-m follow-up (p=0.036). When compared to normal control eyes, FSV in affected eyes was significantly higher at 1-m, 3-m and 6-m follow-up (p<0.05 for all), while FSV in unaffected eyes was significantly higher at baseline, 1-w, 1-m and 3-m follow-up (p<0.05 for all). Three CC patterns of early response to PDT were identified, including signs of recovery with more even flow signals, transient appearance of worse ischemia and secondary neovascularization within CC level.Conclusion: Abnormal CC flow attenuation remains in completely resolved eyes of CCSC patients treated with half-dose PDT.


Heart assist devices are designed for helping damaged hearts maintain sufficient blood flow, for patients getting heart attack with short term and it is used for congestive heart failure patients. The frequency with which the patients are being operated to replace the battery of these devices can be aided and reduced by wirelessly transmitting power. The transcutaneous power transfer for the devices requires charges that move outside the body to induce charges to move inside the body which can ultimately be used to supply energy to the heart pump. WPT is a method of transmitting wireless power using an external primary coil to generate a magnetic field. It passes through the skin and induces current in an implanted secondary coil. The infection caused due to surgery is removed by WPT method. To monitor the charging level of the battery the Wi-fi module is used. It also monitors the corresponding blood flow and the pulse during this function.

Abstract Background: To retrospectively investigate the short-term therapeutic effect of percutaneous vertebroplasty (PVP) for Kummell’s disease using a variable angle needle and to analyze the possible outcome predictors.Methods: Twenty-seven patients were included in this study. Medical records were evaluated. The following factors were analyzed on imaging data: location of lesion, the percentage of bone marrow edema, patterns of cement spreading, and post-procedural kyphosis correction. Visual analogue score (VAS) was used to analyze the clinical effect, and the improvement rate was calculated. Statistical analyses were conducted to evaluate the relationship between those factors and therapeutic outcomes using Fisher’s exact test, Chi-squared test, and Student’s unpaired t-test.Results: The effectiveness rate was 70.4% at 1 week, 74.1% after 1 month, and 63.0% after 3 months. Six months and one year after procedures, the effective rate remained steady at 70.4%. Post-procedural kyphosis correction ≥8° was a risk factor for inferior pain relief. An area of edema over 40% was a prognostic factor for superior pain relief at the first follow-up point. Cement morphology was a positive predictor for better pain relief at 1 month follow-up.Conclusions: Compared to the therapeutic effects of PVP on fresh osteoporotic vertebral compression fractures (OVCF), percutaneous vertebroplasty for Kummell’s disease was effective in only 63% to 74.1% of the patients at different follow-up points. Overemphasized kyphotic correction (over 8 degrees) was associated with poor outcomes. Areas of edema over 40% and cement morphology of mixed type were positive prognostic factors in the early stage.

ABSTRACT Thromboembolism is the most frequent complication in endovascular treatment of intracranial aneurysms, causing disability and death. As stent retrievers have achieved high rates of arterial recanalization in the management of ischemic stroke, these devices were tested as rescue therapy of thromboembolism during aneurysm embolization. We retrospectively analyzed 10 consecutive patients with transprocedural arterial occlusion, treated with mechanical thrombectomy at a single center. Good angiographic recanalization was achieved in eight cases, mTICI 3, 2b and 2a in five, three and two patients, respectively, without additional complications or any deaths. Five patients showed complete recovery (mRS 0) and all patients showed improvement of disability (average mRS 1.1) over a mean follow-up period of 31 months. Eight patients had good clinical recovery, while two remained with deficits (mRS 3 and 4). The study found that the stent retriever is a valuable, rapid and effective tool for restoring blood flow, improving the safety of endovascular treatment.
