Objective: To summarize the clinical characteristics of patients with Takotsubo syndrome (TTS) from China and compare these features with patients from Europe/North America. Methods: We reviewed case reports published between 1990 and 2020 with the key words of "Takotsubo syndrome" "stress cardiomyopathy" "apical balloon syndrome" and "broken heart syndrome", in Wanfang, CNKI, Pubmed and Web of Science databases, and 1 294 articles were identified, including 128 articles reporting 163 cases in China and 1 166 articles reporting 1 256 cases in Europe/North America. The characteristics of demographics, triggers, symptoms, electrocardiogram, echocardiography, left ventriculogram,coronary angiography, treatment and prognosis were analyzed and compared between Chinese and European/North American cases. Results: A total of 1 294 articles (1 419 cases: 163 from China, 1 256 from Europe/North America) were included in the final analysis. The characteristics of Chinese cases included: (1) demographic:the age was (59.6±16.9) years, which was similar with that of European/North American ((59.7±17.4) years, P=0.90), and female accounting for 78.5% (128/163), which was lower than that of European/North American (85.4% (1 073/1 256), P=0.02). (2) Triggers:mental triggers accounted for 48.5% (79/163), physical triggers accounted for 43.6% (71/163), and no triggers accounted for 7.9% (13/163), respectively. Compared with Europe/North America, the ratio of patients with mental triggers was higher in China, while the ratio of patients with physical triggers and no triggers was lower (P<0.05). (3) Symptoms: chest pain (52.8% (86/163)), chest tightness (35.0% (57/163)), shortness of breath (33.1% (54/163)), dizziness (16.0% (26/163)), sweating (15.3% (25/163)), palpitations (12.3% (20/163)), syncope (9.2% (15/163)) abdominal pain/diarrhea (8.6% (14/163)), hypotension (7.4% (12/163)), and fatigue (1.2% (2/163)) were illustrated in sequence. Compared with patients in Europe/North America, the ratio of patients with chest tightness, dizziness, sweating, palpitations, abdominal pain/diarrhea was higher in Chinese patients, while the ratio of patients with hypotension was lower in Chinese patients (P<0.05). (4) Electrocardiogram: main manifestations were myocardial ischemia symptoms, such as ST-segment elevation (63.8% (104/163)), T wave inversion (46.0% (75/163)), ST-segment depression (8.6% (14/163)). Compared with European/North American, the ratio of patients with ST-segment elevation, T wave inversion, and atrioventricular block was higher in Chinese patients (P<0.05). (5) Echocardiography and imaging:apical dyskinesia (59.5% (97/163)) and apical/left ventricular bulbar dilation (36.2%(59/163)) dominated the echocardiography findings. Compared with European/North American, the ratio of patients with apical dyskinesia, apical/left ventricular bulbar dilation, and mitral regurgitation was higher in Chinese patients, while the ratio of patients with dyskinesia in other parts and left ventricular ejection fraction<50% was lower in Chinese patients (P<0.05). Left ventricular angiography showed 36.2% (59/163) of apical dyskinesia in Chinese patients, which was higher than that reported in European/North American patients, and 38.7% (63/163) of apical/left ventricular bulbar dilation was reported in Chinese patients, which was similar to that reported in European/North American patients. Coronary angiography showed percent of no stenosis or stenosis less than 50% was 87.1% (142/163), which was similar to that reported in European/North American patients (P>0.05). The typical type of TTS accounted for 96.3% (157/163), which was significantly higher than that reported in European/ American patients, while the ratio of basal type and midventricular type was lower (P<0.01). (6) Treatment and prognosis:the applied drugs in China were listed in order as following, β-blockers (41.1% (67/163)), antiplatelet agents (37.4%(61/163)), ACEI/ARB (36.2%(59/163)), anticoagulants (27.0%(44/163)), diuretics (19.6% (32/163)), etc. Compared with Europe/North America, the ratio of antiplatelet agents, anticoagulants, statins, diuretics, and nitrates use was higher in China (P<0.05), while the use of oxygen therapy and IABP was similar (P>0.05). The hospital mortality in China was 5.5% (9/163), during 1-year follow-up the recurrence rate was 3.7% (6/163) and the mortality was 0. The prognosis was similar with that in Europe/North America. Conclusions: Compared with TTS cases in Europe/North America, TTS cases in China also occur usually in middle-aged and elderly women, most of whom have mental/physical triggers and typical imaging manifestations, followed by a low hospital mortality rate and recurrence rate.

Tinnitus had been considered a surgically incurable disease, given the failure of several treatment methods. Jannetta reported that tinnitus is one of the hyperactive diseases of the cranial nerve along with hemifacial spasm and trigeminal neuralgia (TGN). Microvascular decompression (MVD) of the eighth cranial nerve was introduced to treat medically intractable tinnitus. Intraoperative monitoring of brainstem auditory evoked potential (BAEP) was able to reduce postoperative complication rates. Less than 1 ms of latency delay and a 40% decrease in amplitude of wave V of the brainstem evoked potential is a landmark of monitoring during surgery. Less than 6 years of duration of tinnitus, normal BAEP before surgery, no accompanying dizziness before surgery and a loop-type offending artery are effective factors for good surgical results of MVD.

OBJECTIVE: Evaluation and analyze the characteristics of balance function in patients with type 2 diabetes, and to find out the importance of proprioception, vision and vestibular in postural control. METHOD: All subjects were divided into two groups, 37 normal individuals, 33 patients with type 2 diabetes mellitus. All were assessed by computerized posturography under six upright stance.conditions: including standing on the firm surface and foam with eyes open and closed. RESULT: (1) On anteroposterior,the scores of proprioception, vision and vestibular were 93.96 ± 7.95, 80.22 ± 16.24, 70.87 ± 20.99, the normal were 98.00 ± 2.18, 91.44 ± 6.01, 80.44 ± 7.81. There were significances between diabetes mellitus group and normal control group (P < 0.05) respectively. (2) On lateral, the scores of vision and vestibular were 80.39 ± 12.60, 73.96 ± 16.04, and the normal were 92.11 ± 4.50, 83.18 ± 9.45. There were significances with P < 0.05 between diabetes mellitus group and normal control group. However, there was no obvious difference in proprioception scores between the two groups. (3) The limit of stability of normal group were (176.47 ± 44.13) mm²; diabetic group was (143.13 ± 62.30) mm². There was statistical significance between the group with P < 0.05. (In diabetic patients, there was no significant difference between the no dizziness group and the dizziness group of the scores of proprioceptive, visual, vestibular as well as stable limits, P > 0.05. CONCLUSION The balance function of patients with type 2 diabetes decreased. It is the main characteristic that the vision and vestibular decreased more significantly in the postural control.

We describe a case involving a 69-year-old woman who developed anaphylatic shock caused by a clinical dose of sugammadex (2 mg/kg, 100 mg intravenously) 5 minutes after its administration. She developed redness and welts all over her body, and complained of an oropharyngeal itching sensation with dyspnea and dizziness. Her vital signs were closely monitored. She also experienced a sudden onset of hypotension (from 110/70 to 49/40 mmHg) and tachycardia (from 75 to 120 bpm). We diagnosed anaphylactic shock on the basis of these clinical manifestations. After 20 min of traditional treatment (hydration, ephedrine, cortisol, and phenylephrine), her vital signs returned to normal. No postoperative complications were evident, and the patient was discharged from the hospital. Although the prevalence of anaphylactic reactions to sugammadex is rare, physicians using sugammadex should be aware of the possibility of sugammadex-induced anaphylaxis.

OBJECTIVE: To analyze and summarize nystagmus of patients with posterior canal benign paroxysmal positional vertigo (BPPV) in positioning test,and to improve the diagnosis and treatment of posterior canal BPPV (PSC-BPPV). METHOD: The present study was conducted on 175 patients who had unilateral BPPV of the posterior semicircular canal (PSC). Their positional nystagmus recorded by videnonystagmography in Dix-Hallpike test,roll test and roll over test were analyzed to summarize the characteristics of nystagmus on nystagmograph of PSC-BP-PV. RESULT: Of the 175 patients, lesion was located in the left PSC in 69 (39.4%) patients,the right PSC in 106 (60. 6%)patients. The nystagmus of patients with PSC-canalithiasis showed upward on the vertical phase of nystagmograph and orientated the different side on horizontal phase in the head hangging position. The horizontal phase pointed to the contralateral side in 47(26. 9%) patients, the ipsilateral contralateral side in 100(57. 1%) patients,no significant reverse ingredients in 28(16.0%) patients. When these patients returned to sit,139(79.4%) patients showed down beating positioning nystagmus, whereas 36 (20. 6%) patients with no nystagmus only had a short vertigo or dizziness. The horizontal phase of the 139 patients pointed to the contralateral side in 40(22. 9%) patients,the ipsilateral contralateral side in 68(38. 9%) patients,no significant reverse ingredients in 31(17. 7%) patients. In roll test,12 patients of the right PSC-BPPV presented an up-beating rotatory nystagmus when the head turned to right,and 5 patients of the left PSC-BPPV presented a down-beating rotatory nystagmus when the head turned to left. When the patients changed body from the left lateral position to the right lateral position in the roll over test, 74(42. 3%) patientsshowed vertical positioning nystagmus. In 30 patients who presented an up-beating nystagmus, there were 25(83. 3%) patientscame from the right PSC-BPPV. In 44 patients who presented a down-beating nystagmus, there were 36(81. 8%) patientscame from the left PSC-BPPV. The direction of the vertical nystagmus was highly correlated with the judgment about the side of the PSC-BPPV in roll over test (P<0. 01). CONCLUSION The patient with PSC-canalithiasis showed an uncertain direction in torsional nystagmus in Dix-Hallpike test,the diagnosis was mainly concern with the vertical nystagmus. When we found a rotatory nystagmus with much more up-beating nystagmus in roll test, it might be PSC-BPPV. We also can use the roll over test to diagnose the location of the otolith in which side of the PSC-BPPV.

OBJECTIVE: To analyze clinical features with benign paroxysmal positional vertigo (BPPV) and discuss the attentions in the canalith repositioning procedures. METHOD: A total of 76 male and female patients aged 80 and over with BPPV (elderly group) and 76 patients aged 60-65 years old with BPPV (older group) was retrospectively analyzed. RESULT: (1)Semicircular canal condition: in elderly group, posterior semicircular canal was involved in 72 cases, whereas the horizontal semicircular 4 cases. In older group, posterior semicircular canal was involved in 70 cases, whereas the horizontal semicircular and multiple canals in 5 cases and 1 case respectively. (2) Precipitating factors: precipitating factors of elderly were variety. Its closely related with emotion, infection, seasonal alternation surgery, and trauma. There were significant differences between the two groups (P<0. 05). (3) The symptoms of undergoing treatment and post-treatment: the duration of dizziness and carebaria were significant difference after canalith repositioning procedure treatment between two groups (P<0. 05), the duration of balance disturbance and symptoms of vegetative nerve functional disturbance like nausea and sweating were significant difference (P<0. 05). (4) Treatment and outcomes: the remission, partial remission rate were 34. 2 %, 81. 6% re- spectively, after the first or second time of repositioning treatment. The efficacy of repositioning treating at the first time was significantly different between two groups (P<0. 05). It was poor efficacy in elderly group. There is no difference in efficacy for repositioning treatment at the second or third time (P>0. 05). (5) The elderly always accompanied with other medical condition and had risk factors of cerebrovascular disease. The efficacy was not associated with the complication(P>0.05). However, it was most likely to overtreatment caused by emphasizing other medical conditions treatment. BPPV was easy to ignore and misdiagnose, meanwhile, delayed the diagnosis and increased the medical costs. (6) Many elderly were accompanied cervical spondylosis, lumbar spondylosis body stiffness and fear of vertigo which increased the difficulty of repositioning treatment. (7) Recurrence: we followed up 2 years after treatment. In older group, 11 patients (14. 5%)were relapsed. In elderly group, 29 patients (38. 2%) relapsed. There were significant differences between the two groups (P<0. 05). CONCLUSION There are various precipitating factors in elderly patients with BPPV, the most frequent precipitating factors were related to psychological factor and overfatigue. The symptoms of the patients attack BPPV was always mask with other diseases, but do not impact on the efficacy of Canalith repositioning at the first time; Even the efficacy of repositioning is poor at the first time, it's effective and safety after multiple treatments of repositioning; It prolonged the symptoms including carenaria, dizziness and nausea after treatment.

OBJECTIVE: This retrospective study compared clinical manifestations of idiopathic sudden hearing loss between children and the elderly. METHOD: 44 pediatric patients and 76 elderly patients diagnosed with idiopathic sudden deafness in our clinic from December 2009 to September 2014 were enrolled. Different clinical parameters were compared. RESULT: The incidence of initially profound hearing loss was highest and mild hearing loss was lowest in both groups (P < 0.05). There were no differences in the proportion with initially mild, moderate, severe, and profound hearing loss between both groups (P > 0.05). The number of patients was the most in initially profound type of audiogram pattern and the fewest in ascending type in both groups (P < 0.05). Hearing recovery rates in children (27/44, 61.4%) was higher than that in elderly patients (32/76, 42.1%) (P < 0.05). There were no differences in hearing recovery rates of the patients with initially level of hearing loss in both groups (P > 0.05). The highest recovery rate in children was in those with descending type and the lowest was in those with profound type (P < 0.05). There were no differences in hearing recovery rates in elderly patients with initially different types of audiogram pattern (P > 0.05). Hearing recovery rates of descending type in children were higher than that in elderly patients. Presence of tinnitus in pediatric patients was not relavent to the outcome (P > 0.05). Presence of tinnitus in elderly patients was associated with favorable outcomes. (P < 0.05). Presence of dizziness in pediatric patients was not relavent to the outcome (P > 0.05). Presence of dizziness in elderly patients was associated with poor outcomes (P < 0.05). Presence of initially different degrees of opposite side hearing loss in elderly patients was not relavent to the outcome (P > 0.05). Presence of chronic diseases in elderly patients was not associated with the outcome (P > 0.05). CONCLUSION The clinical manifestion of idiopathic sudden deafness is respective in Children and in elderly patients.

A 26-yr-old male patient reported worsened dyspnea, dizziness one year after an emergency Bentall operation for type A aortic dissection. There was evidence of hemolytic anemia and aortogram revealed a significant stenosis at the distal anastomosis site. During the reoperation, we found the inner felt at the distal anastomosis was inverted causing a significant stenosis. The reoperation successfully resolved this problem. Here, we report a rare case of hemolytic anemia caused by an inverted inner felt after Bentall operation.
