BACKGROUND The incidence of acute myocardial infarction(AMI)is rising,with cardiac rupture accounting for approximately 2%of deaths in patients with acute ST-segment elevation myocardial infarction(STEMI).Ventricular free wall rupture(FWR)occurs in approximately 2%of AMI patients and is notably rare in patients with non-STEMI.Types of cardiac rupture include left ventricular FWR,ventricular septal rupture,and papillary muscle rupture.The FWR usually leads to acute cardiac tamponade or electromechanical dissociation,where standard resuscitation efforts may not be effective.Ventricular septal rupture and papillary muscle rupture often result in refractory heart failure,with mortality rates over 50%,even with surgical or percutaneous repair options.CASE SUMMARY We present a rare case of an acute non-STEMI patient who suffered sudden FWR causing cardiac tamponade and loss of consciousness immediate before undergoing coronary angiography.Prompt resuscitation and emergency open-heart repair along with coronary artery bypass grafting resulted in successful patient recovery.CONCLUSION This case emphasizes the risks of AMI complications,shares a successful treatment scenario,and discusses measures to prevent such complications. 展开更多

An earthquake of Ms 8 struck Wenchuan County, western Sichuan, China, on May 12^th, 2008 and resulted in long surface ruptures (〉300 km). The first-hand observations about the surface ruptures produced by the earthquake in the worst-hit areas of Yingxiu, Beichuan and Qingchuan, ascertained that the causative structure of the earthquake was in the central fault zones of the Longmenshan tectonic belt. Average co-seismic vertical displacements along the individual fault of the Yingxiu-Beiehuan rupture zone reach 2.514 m and the cumulative vertical displacements across the central and frontal Longmenshan fault belt is about 5-6 m. The surface rupture strength was reduced from north of Beichuan to Qingchuan County and shows 2-3 m dextral strike-slip component. The Wenchuan thrust-faulting earthquake is a manifestation of eastward growth of the Tibetan Plateau under the action of continuous convergence of the Indian and Eurasian continents. 展开更多

The Garzê–Yushu strike-slip fault in central Tibet is the locus of strong earthquakes(M 〉 7). The deformation and geometry of the co-seismic surface ruptures are reflected in the surface morphology of the fault and depend on the structure of the upper crust as well as the pre-existing tectonics. Therefore, the most recent co-seismic surface ruptures along the Garzê–Yushu fault zone(Dangjiang segment) reveal the surface deformation of the central Tibetan Plateau. Remote sensing images and field investigations suggest a 85 km long surface rupture zone(striking NW-NWW), less than 50 m wide, defined by discontinuous fault scarps, right-stepping en echelon tensional cracks and left-stepping mole tracks that point to a left-lateral strike-slip fault. The gullies that cross fault scarps record systematic left-lateral offsets of 1.8 m to 5.0 m owing to the most recent earthquake, with moment magnitude of about M 7.5, in the Dangjiang segment. Geological and geomorphological features suggest that the spatial distribution of the 1738 co-seismic surface rupture zone was controlled by the pre-existing active Garzê–Yushu fault zone(Dangjiang segment). We confirm that the Garzê–Yushu fault zone, a boundary between the Bayan Har Block to the north and the Qiangtang Block to the south, accommodates the eastward extrusion of the Tibetan Plateau and generates strong earthquakes that release the strain energy owing to the relative motion between the Bayan Har and Qiangtang Blocks. 展开更多

Field investigations allow to constrain the co-seismic surface rupture zone of ~400 km with a strike-slip up to 16.3 m associated with the 2001 Mw 7.8 Central Kunlun earthquake that occurred along the western segmentof the Kunlun fault, northern Tibet. The co-seismic rupture structures are almost duplicated on the pre-existing fault traces of the Kunlun fault. The deformational characteristics of the co-seismic surface ruptures reveal that the earthquake had a nearly pure strike-slip mechanism. The geologic and topographic evidence clearly shows that spatialdistributions of the co-seismic surface ruptures are restricted by the pre-existing geological structures of the Kunlun fault. 展开更多

With co-seismic surface rupture slip displacements provided by the field observation for the 2001 MS8.1 West Kunlun Mountain Pass earthquake, this paper estimates the rupture speed on the main faulting segment with a long straight fault trace on the surface based on a simple slip-weakening rupture model, in which the frictional overshoot or undershoot are involved in consideration of energy partition during the earthquake faulting. In contrast to the study of Bouchon and Vallée, in which the rupture propagation along the main fault could exceed the local shear-wave speed, perhaps reach the P-wave speed on a certain section of fault, our results show that, under a slip-weakening assumption combined with a frictional undershoot (partial stress drop model), average rupture speed should be equal to or less than the Rayleigh wave speed with a high seismic radiation efficiency, which is consistent with the result derived by waveform inversion and the result estimated from source stress field. Associated with the surface rupture mechanism, such as partial stress drop (frictional undershoot) associated with the apparent stress, an alternative rupture mechanism based on the slip-weakening model has also been discussed. 展开更多

On December 18, 2023, the M_(S)6.2 Jishishan earthquake occurred in the northeastern region of the QinghaiXizang Plateau, causing heavy casualties and property damage in Gansu and Qinghai Provinces. In this study,we integrate space imaging geodesy, finite fault inversion, and back-projection methods to decipher its rupture property, including fault geometry, coseismic slip distribution, rupture direction, and propagation speed. The results reveal that the seismogenic fault dips to the southwest at an angle of 29°. The major slip asperity is dominated by reverse slip and is concentrated within a depth range of 7–16 km, which explains the significant uplift near the epicenter observed by both the Sentinel-1 ascending and descending In SAR data. Moreover, the teleseismic array waveforms indicate a northwest propagating rupture with an overall slow rupture velocity of~1.91 km/s(AK array) or 1.01 km/s(AU array). 展开更多

In this study,the vertical components of broadband teleseismic P wave data recorded by China Earthquake Network are used to image the rupture processes of the February 6th,2023 Turkish earthquake doublet via back projection analysis.Data in two frequency bands(0.5-2 Hz and 1-3 Hz)are used in the imaging processes.The results show that the rupture of the first event extends about 200 km to the northeast and about 150 km to the southwest,lasting~90 s in total.The southwestern rupture is triggered by the northeastern rupture,demonstrating a sequential bidirectional unilateral rupture pattern.The rupture of the second event extends approximately 80 km in both northeast and west directions,lasting~35 s in total and demonstrates a typical bilateral rupture feature.The cascading ruptures on both sides also reflect the occurrence of selective rupture behaviors on bifurcated faults.In addition,we observe super-shear ruptures on certain fault sections with relatively straight fault structures and sparse aftershocks. 展开更多

Splenic injury associated with fetal death in utero following a fall from a tree top is even rarer. The authors report a case of splenic trauma associated with fetal death in utero following a fall from the top of a tree in a 19-year-old pregnant woman at 30 weeks amenorrhoea. She was referred from a 1st level health facility for trauma that had occurred the day before admission. She was in poor general condition (WHO performance status IV) and had a cardiovascular collapse. Ultrasound was used to diagnose haemoperitoneum and fetal death in utero. A CT scan was used to diagnose splenic lesions. Treatment consisted of splenectomy and caesarean section after resuscitation. 展开更多

The subsurface fluid injection can cause pressure increase within faults,leading to earthquake occurrences.However,the factors controlling earthquake rupture due to pressure perturbation remain poorly understood.To resolve this problem,we simulate the physical processes of earthquake nucleation and rupture on strike-slip faults perturbated by pressure migration based on the slip-weakening law.Multiple kinds of factors,including background stress,fluid injection rates,the area of the pressurized region,fault geometry,and fault friction coefficients,are considered in our simulations.Our simulation results reveal that the ratio of shear stress to normal stress rather than their absolute values controls the rupture behavior.With the large stress ratios,high injection rates,and large pressurized areas,earthquakes are prone to propagate as runaway ruptures.Additionally,faults with large aspect ratios of length to width are also favorable for causing runaway ruptures.In contrast,the factors of fault strike,dip angles and friction coefficients have minor influence on rupture behavior. 展开更多

Introduction: The aim of this study was to contribute to improving the quality of GEUR management in the general surgery department and in the maternity ward of the Ignace Deen national hospital, Conakry University Hospital. Methodology: This was a retrospective, descriptive study lasting two years (January 1, 2020 to December 31, 2022), carried out in the general surgery and gyneco-obstetrics departments of the Ignace Deen national hospital, Conakry University Hospital. We included all patients with a ruptured ectopic pregnancy who received surgical treatment during the study period. Results: We collected 13,524 cases of surgical interventions in the two services, among them, we recorded 89 cases or 0.66% GEUR. The average age of the patients was 24.26 years. Brides were the most represented with 80.96% of cases. Women practicing a liberal profession were 51.69% (n = 46) and housewives 26.97% (n = 24). Clinically, amenorrhea was noted in all patients, i.e. 100%, abdominal-pelvic pain in 95.2% (n = 85) of cases, metrorrhagia in 94.08% (n = 84), abdominal-pelvic sensitivity in 97.44% (n = 87) of cases and anemia in 85.39% of cases. The GEUR was ampullary in 69.66% (n = 62) cases. Salpingectomy was performed in 90.72% (n = 81). The surgical outcomes were satisfactory in 98.87% (n = 88) of cases. We recorded one case of surgical site infection. We have not recorded any deaths. The average length of hospitalization was 4 days. Conclusion: GEUR is relatively high in our context. A good understanding of the prognostic factors of GEUR, awareness and family planning could reduce GEUR. 展开更多

Objective: The objective of this study was to determine if early rupture of membranes (ROM) in women undergoing induction of labor (IOL) at term is associated with an increased rate of clinical chorioamnionitis. Study Design: A retrospective cohort study was performed on women undergoing IOL. Early ROM was defined as ROM at a modified Bishop score less than 5, cervical dilation less than 4 cm, or cervical effacement less than 80%. The rate of clinical chorioamnionitis was compared between women with early and late ROM. Results: The rate of clinical chorioamnionitis was 8.6% (24/279). ROM at an effacement of less than 80% was associated with a rate of clinical chorioamnionitis of 15.4% (12/78) compared to 6.0% (12/201) at an effacement of equal to or greater than 80%, p = 0.017. The rate of cesarean delivery was higher for patients with early ROM by any definition: 32% compared to 17.5% by modified Bishop score (p = 0.031), 32.4% versus 18.2% by cervical dilation (p = 0.049), and 33.3% versus 14.9% by cervical effacement (p = 0.001). Conclusions: In patients undergoing IOL, early ROM may be associated with an increased rate of clinical chorioamnionitis when performed at a cervical effacement of less than 80% and an increased rate of cesarean delivery. 展开更多

Purpose: Neonatal pneumonia is a major newborn disease with a high morbidity rate. We aimed to evaluate whether atypical prelabor rupture of membranes (PROM) is a high-risk factor for causing neonatal pneumonia in a prospective real-world study. Patients and Methods: A total of 250 pregnant women at pregnancy week 39 were non-selectively recruited. All were examined by PROM and neonatal pneumonia related clinical, bedside and lab tests, including body temperature, blood pressure, increased vagina discharge, posterior vault pooling, abdominal tenderness, WBC count, nitrazine test, amniotic fluid index, Leakection (a sICAM-1 based lateral flow immunoassay) and vagina streptococcus examinations. Increased vagina discharge with a Leakection positivity was adopted as a working criterium for identifying atypical PROM. Neonatal pneumonia was diagnosed based on the clinical presentation and lab tests. Results: Twenty cases of neonatal pneumonia (8.0%) were diagnosed after the deliveries of the 250 pregnant women. In these neonatal pneumonia cases, 12 (16.7%) occurred in 72 deliveries with atypical PROM, 2 (16.7%) in 12 deliveries with typical PROM, and 6 (3.6%) in 166 deliveries with non-PROM. Conclusion: In this real-world study, we find that a systematic screening at pregnancy week 39 was very meaningful in revealing atypical PROM. Moreover, atypical PROM is a major risk factor for neonatal pneumonia. Therefore, an early diagnosis and intervention on atypical PROM could potentially reduce the occurrence of neonatal pneumonia. 展开更多

BACKGROUND Severe bleeding as a result of a major vascular injury is a potentially fatal event commonly observed in the emergency department.Bowel necrosis and gastric ulcers secondary to ischemia are rare due to their rich blood supply.In this case,we present the case of a patient who was treated successfully following rupture of his femoral artery resulting in bowel necrosis and an unusually large gastric ulcer.CASE SUMMARY A 28-year-old male patient sustained a knife stab wound to the right thigh,causing rupture of his femoral artery and leading to massive bleeding.He underwent cardiopulmonary resuscitation and received a large blood transfusion.Abdominal surgeries confirmed bowel necrosis,and jejunostomy was performed.The necrotic intestine was removed,the remaining intestine was anastomosed,and the right thigh was amputated.After three surgeries,the patient's overall condition gradually improved,and the patient was discharged from the hospital.However,one day after discharge,the patient was admitted again due to dizziness and melena,and a gastroduodenoscopy revealed a giant banded ulcer.After 2 weeks of treatment,the ulcer had decreased in size without bleeding.Six months after the last surgery,enterostomy and reintroduction surgery were completed.The patient was fitted with a right lower limb prosthesis one year after surgery.After 3 years of follow-up,the patient did not complain of discomfort.CONCLUSION Trauma department physicians need to be aware of the possible serious complications involving the abdomen of trauma patients with massive bleeding. 展开更多

Following surface rupture observations in populated areas affected by the KahramanmaraşEarthquake(Mw 7.7)on February 6th,2023,along the Pazarcık segment of the East Anatolian Fault Zone(EAFZ),this study presents novel insights into physical criteria for delineating surface fault-rupture hazard zones(SRHZs)along ruptured strike-slip faults.To achieve this objective,three trench studies across the surface rupture were conducted on the Pazarcık segment of the EAFZ to collect field data,and earthquake recurrence intervals were interpreted using Bayesian statistics from previously conducted paleoseismological trenchings.The results of the proposed model indicate that the Pazarcık segment produced five significant surface-rupturing earthquakes in the last∼11 kyr:E1:11.13±1.74 kyr,E2:7.62±1.20 kyr,E3:5.34±1.05 kyr,E4:1.82±0.93 kyr,and E5:0.35±0.11 kyr.In addition,the recurrence intervals of destructive earthquakes on the subject in question range from 0.6 kyr to 4.8 kyr.Considering that the last significant earthquake occurred in 1513,the longest time since the most recent surface fault rupturing earthquake on this particular segment was 511 years.These results indicate that,in terms of the theoretical recurrence interval of earthquakes that can create surface ruptures on the Pazarcık segment,the period in which the February 6,2023,earthquake occurred was within the end of the expected return period.As a result,the potential for a devastating earthquake in the near future is not foreseen on the same fault.Finally,the SRHZ proposed for the Pazarcık section of Gölbaşıvillage was calculated as a 61-meter-wide offset on the fault lineament to reduce the negativities that may occur in the ruptured area in the future.It is recommended to take into account this width in the settlement of this area and nearby areas. 展开更多

BACKGROUND Splenic rupture associated with Behçet’s syndrome(BS)is extremely rare,and there is no consensus on its management.In this case report,a patient with BSassociated splenic rupture was successfully treated with splenic artery embolization(SAE)and had a good prognosis after the intervention.CASE SUMMARY The patient was admitted for pain in the left upper abdominal quadrant.He was diagnosed with splenic rupture.Multiple oral and genital aphthous ulcers were observed,and acne scars were found on his back.He had a 2-year history of BS diagnosis,with symptoms of oral and genital ulcers.At that time,he was treated with oral corticosteroids for 1 month,but the symptoms did not alleviate.He underwent SAE to treat the rupture.On the first day after SAE,the patient reported a complete resolution of abdominal pain and was discharged 5 d later.Three months after the intervention,a computed tomography examination showed that the splenic hematoma had formed a stable cystic effusion,suggesting a good prognosis.CONCLUSION SAE might be a good choice for BS-associated splenic rupture based on good surgical practice and material selection. 展开更多
