RESUMEN

INTRODUCTION: Spontaneous tendon rupture (STR) is one of the complications related to hyperparathyroidism. This study aims to verify this and to elucidate the feasibility of combined incidence rate of STR and bony fracture to assess clinical management of renal bone disease in dialysis cohort. METHOD: This is a clinical audit of cases of STR and fracture with 5504 patient-year dialysis vintage over 10 years. In order to verify the risk factor, comparison of cases of tendon rupture, the gender, and dialysis vintage matched patients without tendon rupture were done, followed by comparison with post-parathyroidectomy patients. RESULT: Six cases of STR involving eight tendons were identified, including a case of concurrent tendon rupture and bony fracture. These include two cases of double tendons ruptures. During this time, there were 15 cases of bony fracture without tendon rupture. The overall incidence rate for STR and fracture was of 0.0011 and 0.0029 incidence per year of dialysis vintage or one case per 917 and 344 patient-year dialysis vintage, respectively. For patients with PTH ≥ 600 pg/mL, the incidence rate of tendon rupture and fracture was 0.0199 and 0.0430 incidence per person-years or one case per 50 and 23 person-years, respectively. For patients with PTH < 600 pg/mL, the respective rate was 0 and 0.0006 incidence per person-years or one case per >5202 and 1734 person-years. There was significant difference for incidence rates of tendon rupture and fracture between these two groups, with six incidences of tendon rupture per 302 patient-dialysis-years of PTH ≥ 600 pg/mL versus 0 incidence per 5202 patient-year dialysis vintage of PTH < 600 pg/mL (p < 0.001). In similar comparison, there was also significant difference for incidence rate of fracture with 13/302 versus 2/5202 (p < 0.001). In the 5 yearly audit over 10 years, the incidence rates of tendon rupture and fracture have dropped from 0.0052 to 0.0028 or one incidence per 192 to 356 person-years. Among 35 patients post-parathyroidectomy, there was an incidence of tendon rupture in a patient with recurrence of hyperparathyroidism, 5 years after surgery. Comparing six survived patients with tendon rupture versus 12 age-gender-dialysis vintage matched patients, hyperparathyroidism has been shown to be most important risk factor. And subsequently, comparing them with six post-parathyroidectomy patients, reduction of alkaline phosphatase (ALP) has been shown to be associated with lower risk of tendon rupture. Median survival in patients with history of tendon rupture and those with history of fracture was 5.9 and 2.2 years, respectively (p = 0.192). CONCLUSION: Although rare, end-stage renal failure patients on dialysis with PTH > 600 pg/mL had high risk of tendon rupture and bony fracture. Parathyroidectomy might reduce the risk of tendon rupture and fracture with lowering ALP signifying reduction in bone turn over. Combined incidence rate of tendon rupture and fracture could be used to assess the control of hyperparathyroidism related issues in dialysis center.

RESUMEN

OBJECTIVE: We aimed to assess the rates of overall diagnosis of ectopic pregnancy (EP), treatment modality and associated complications during the COVID-19 pandemic compared to the exact time period in the previous year (pre-COVID-19). METHODS: A retrospective cohort study was conducted at a single referral regional center (Shaare Zedek Medical Center, Jerusalem, Israel). Prevalence of the diagnosis of EP, treatment modality and associated complications during the COVID-19 lockdown period in the state of Israel (March 10-May 12, 2020) was compared to patients receiving the same diagnosis during the parallel timeframe in the previous year (2019). RESULTS: Overall there were 29 and 43 cases of EP during the COVID-19 and pre COVID-19 epoch, respectively. COVID-19 period patients presented to the emergency room with significantly higher ß-human chorionic gonadotrophin level; median of 1364 versus 633 IU, P = 0.001. The rate of ruptured EP was; 20.7% versus 4.3% P = 0.031, and surgical approach; 55.2% versus 27.9%, P = 0.001. Significantly higher median volume of blood loss; median volume 852 versus 300 ml, P = 0.042 were observed in patients during the COVID-19 epoch. CONCLUSION: The COVID-19 pandemic led to delayed presentation of patients with EP, and the requirement of subsequent emergency surgical management and excessive blood loss. Special attention should be given to the decline in routine medical care during the pandemic.

RESUMEN

OBJECTIVE: During the 2020 COVID-19 pandemic there was a decrease in emergency room arrivals. There is limited evidence about the effect of this change in behavior on women's health. We aimed to evaluate the impact of the COVID-19 pandemic on the diagnosis, treatment and complications of women presenting with a tubal Ectopic Pregnancy (EP). STUDY DESIGN: This is a single centre retrospective cohort study. We compared the clinical presentation, treatment modalities and complications of all women presenting in our institution with a tubal EP during the COVID-19 pandemic between 15 March and 15 June 2020, with women who were treated in our institution with the same diagnosis in the corresponding period for the years 2018-2019. RESULTS: The study group included 19 cases of EP (N = 19) that were treated between the 15 March 2020 and 15 June 2020. The control group included 30 cases of EP (N = 30) that were admitted to in the corresponding period during 2018 and 2019. Maternal age, parity, gravity and mode of conception (natural vs. assisted) were similar between the two groups. There was no difference in the mean gestational age (GA) according to the last menstrual period. In the study group more women presented with sonographic evaluation of high fluid volume in the abdomen than in the control group (53 % vs 17 %, P value 0.01). This finding is correlated with a more advanced disease status. In the study group there was a highly statistically significant 3-fold increase in rupture among cases (P < 0.005) and a 4-fold larger volume of blood in the entrance to the abdomen (P < 0.002). We found that there were no cases of ruptured EP in the group of women who were pregnant after assisted reproduction. CONCLUSION: We found a higher rate of ruptured ectopic pregnancies in our institution during the COVID-19 pandemic. Health care providers should be alerted to this collateral damage in the non-infected population during the COVID-19 pandemic.

RESUMEN

PURPOSE: To determine the risk factors of intraoperative cyst rupture in partial nephrectomy (PN) for a cystic renal mass (CRM) and their effect on the prognosis of patients. MATERIALS AND METHODS: Patients who underwent partial nephrectomy for CRMs from January 2009 to January 2015 were included. Uni/multivariate Logistic/Cox analysis and Kaplan-Meier analysis were performed. RESULTS: A total of 174 patients were included in this study. There were 27 (15.5%) intraoperative cyst ruptures. The median follow-up time was 60 months. Multivariate logistic analysis showed that the E component (P = 0.018) and N component (P = 0.022) of the R.E.N.A.L. nephrometry score, Bosniak category III (P = 0.044), and surgeon's experience (P = 0.030) were risk factors associated with intraoperative cyst rupture in PN for CRMs. The 5-year recurrence-free survival (RFS), cancer-free survival (CFS) and overall survival (OS) were 92.7%, 90.32% and 94.4%, respectively, in 124 cases of malignant CRM. Kaplan-Meier analysis demonstrated that 5-year RFS and 5-year CFS in patients with cyst rupture was worse than those without cyst rupture (P = 0.006 and 0.003, respectively). Multivariate Cox analysis revealed that intraoperative cyst rupture was independent risk factor for 5-year RFS and 5-year CFS (P = 0.039 and 0.013, respectively). However, there was no significant difference in OS between the two groups (P = 0.275). CONCLUSIONS: The prevalence of intraoperative cyst rupture is relatively high. Higher E and N scores, Bosniak category III, and lacking surgical experience (<20 cases) increase the risk of occurrence of intraoperative cyst rupture.

RESUMEN

Objective: To investigate the clinical characteristics and early identification of spontaneous rupture of uterus caused by placenta percreta. Methods: The clinical data of 12 patients with spontaneous uterine rupture caused by placenta percreta and admitted to the First Affiliated Hospital of Zhengzhou University from June 2014 to December 2019 were collected. The age, gestational age, gestational history, clinical manifestations, diagnostic methods, uterine operation history, rupture location, surgical method, treatment and outcome were analyzed. Results: (1) General condition: the median age of pregnant women was 37 years (range: 30-43 years), and the median gestational week of uterine rupture was 29+6 weeks (range: 18+3-36+3 weeks). (2) Clinical manifestation: among the 12 pregnant women, 9 showed different degrees of abdominal pain; chest distress accompanied by waist soreness, abdominal distension in 2 cases; one asymptomatic pregnant women was found with uterine rupture during elective cesarean section. Preoperative color Doppler ultrasonography indicated that 9 of the 12 pregnant women had peritoneal effusion, and 6 of them underwent diagnostic peritoneal puncture or posterior vault puncture for non-clotting blood extraction. (3) Uterine operation history and rupture location: among the 12 cases of spontaneous rupture of uterus caused by placenta percreta pregnant women, 10 had placenta previa after cesarean section, including 4 cases of rupture at the incision of the original cesarean section, 3 cases of rupture at the penetrating placental implantation of the lower segment of the anterior wall of the uterus, and 1 case of placenta percreta occurred at the myomectomy site of the right angle of the uterus. Among the 2 pregnant women with spontaneous uterine rupture caused by penetrating placental implantation without a history of cesarean section, 1 case with history of multiple abortions, and uterine rupture occurred at the bottom of the palace, 1 had rupture of placental penetrating implantation after hysteroscopic electroresection of endometrial polyps, and the uterine rupture occurred at the anterior wall of the lower segment of the uterus. (4) Maternal and fetal outcomes: 11 pregnant women were injected with suspension RBC and 1 pregnant woman was not injected with blood products. Nine cases underwent hysteroplasty and 3 cases underwent subtotal hysterectomy. There were 11 maternal survivors and 1 maternal death; 7 neonates survived and 6 stillbirths. Conclusions: Uterine rupture caused by placenta percreta is of great harm to mother and infant, due to its heterogeneity in clinical manifestations, which increases the possibility of misdiagnosis. For pregnant women with risk factors of placenta percreta, early diagnosis should be made during pregnancy. For those who have been diagnosed with placenta percreta, when there is typical or atypical uterine rupture, doctors should be alert to the occurrence of uterine rupture.

RESUMEN

BACKGROUND: This study is the largest cohort of partial distal biceps brachii tendon ruptures in the literature that was analyzed according to rupture morphology of the long and short tendon heads. METHODS: Patients with partial distal biceps tendon ruptures were identified using an institutional enterprise data warehouse query at a single institution. A retrospective chart review was performed to record patient demographics, past medical history, and injury mechanism for each patient. Each patient's magnetic resonance images were reviewed to determine injury patterns, specifically the extent of long head (LH) and short head (SH) tendon involvement, and associated injuries. Rupture morphologies were correlated with mechanism of injury, diabetes status, and smoking history. RESULTS: Seventy-seven patients were included in the study. The average age was 52 years (±11.9, range: 23-90 years); 67% were male, with an average body mass index of 28.3 (±4.3). A smoking history was reported in 31.2% of patients and 5.2% were diabetic. The partial ruptures were caused by a traumatic mechanism in 57.1% of cases, 23.4% were atraumatic, and 19.5% had an unknown mechanism. The most common injury morphology was a partial LH rupture with an intact SH tendon (33.8%). Isolated complete ruptures of the LH represented the least common injury morphology. Injury morphology was significantly related to mechanism (P < .01). Traumatic ruptures had a higher percentage of SH involvement compared with the atraumatic group (77.3% vs. 37.7%, respectively). In contrast, atraumatic ruptures involved the LH tendon in 89% of cases, with only 37.7% of cases involving the SH tendon. Patients with a history of smoking were more likely to have an atraumatic mechanism (P = .01). A history of diabetes was unrelated to mechanism (P = .20). CONCLUSION: Partial ruptures of the distal biceps brachii tendon represent a spectrum of patterns with varying involvement of the LH and SH tendons. Injury morphology was significantly related to mechanism (P < .01). LH tendon involvement was seen in 88.9% of atraumatic cases, whereas SH tendon involvement was seen in 77.3% of traumatic cases. A more comprehensive understanding of partial rupture patterns is critical to further understand the risk factors that may preclude to worse clinical outcomes, and aid in deciding which patients would benefit from operative vs. nonoperative management.

RESUMEN

BACKGROUND: It has been widely documented that circannual variation has an impact on the incidence and prognosis of cardiovascular diseases. It is unclear why cold ambient temperature increase the incidence of acute myocardial infarction (AMI). We investigated the relationship between the ambient temperature at the onset of AMI, the morphology of the culprit lesion in patients with AMI. METHODS: We investigated 202 consecutive patients with AMI who underwent optical coherence tomography (OCT). The participants were divided into lower (n = 100) and higher (n = 102) temperature groups based on the ambient temperature. The culprit lesion morphology was compared between the two groups. RESULTS: The median temperature at the onset of AMI was 16.6 °C. The prevalence of plaque ruptures was higher at lower temperatures (lower 66% vs. higher 45%, p = .003), whereas OCT-erosion was more frequent in the higher temperature group (lower 13% vs. higher 26%, p = .021). The lower temperature group showed more cholesterol crystals (lower 71% vs. higher 54%, p = .014). CONCLUSION: The peak incidence of AMI in the winter is formed by increased plaque rupture, suggesting environmental temperature has an influence on the pathogenesis of AMI.

RESUMEN

BACKGROUND: Hepatoblastoma tumor rupture is a high-risk criterion in the SIOPEL 3/4 protocol. Little is known about the outcome of these children. METHODS: Radiological signs of possible tumor rupture, defined as peritoneal effusion, peritoneal nodules, or hepatic subcapsular hematoma, were reported in 24 of 150 patients treated for hepatoblastoma in France from January 2000 to December 2014 after central radiological expert review. RESULTS: Twenty-two patients with available clinical data were included (nine PRETEXT-I/II, six PRETEXT-III, seven PRETEXT-IV, and five had lung metastases). Five patients had a subcapsular hematoma only, and 17 patients had intraperitoneal rupture (subcapsular hematoma and peritoneal effusion). A hepatic biopsy was performed in 19 patients. Intraperitoneal rupture occurred before biopsy in 12 and after biopsy in three (including one with prebiopsy subcapsular hematoma) (missing data: two). All patients were treated with chemotherapy, with high-risk regimens including cisplatin or carboplatin and doxorubicin in 19 and cisplatin or carboplatin alone in three. Liver surgery was performed in 20 patients (including three liver transplants). Fifteen patients (68%) achieved complete remission. With a median follow-up of 5.5 years, 11 events occurred (six progressions and three relapses, including three peritoneal progressions/relapses, one surgical complication, and one second cancer) and eight patients died. One of eight patients with no other high-risk criterion had a relapse. The three-year event-free survival and overall survival rates were 49.6% (95% CI = 30-69) and 68.2% (40-84), respectively. CONCLUSIONS: Tumor rupture is predictive of poor prognosis with risk of peritoneal progression/relapse. However, it should not be a contraindication for liver transplantation.

RESUMEN

BACKGROUND: Surveillance imaging of previously unruptured, coiled aneurysms remains routine even though reports of rupture of these aneurysms are extremely rare. PURPOSE: We performed meta-analysis to examine long-term rupture risk over ≥1-year follow-up duration in patients with unruptured intracranial aneurysm who underwent endovascular therapy. DATA SOURCES: Multiple databases were searched for relevant publications between 1995 and 2018. STUDY SELECTION: Studies reporting outcome of long-term rupture risk over ≥1-year follow-up in treated patients with unruptured intracranial aneurysms were included. DATA ANALYSIS: Random effects meta-analysis was used, and results were expressed as long-term rupture rate per 100 patient-year with respective 95% CIs. For ruptured aneurysms during follow-up, data were collected on size and completeness of initial Treatment. DATA SYNTHESIS: Twenty-four studies were identified. Among 4842 patients with a mean follow-up duration of 3.2 years, a total of 12 patients (0.25%) experienced rupture of previous unruptured intracranial aneurysms after endovascular treatment. Nine of these 12 patients harbored aneurysms that were large, incompletely treated, or both. A total of 2 anterior circulation, small, completely coiled aneurysms subsequently ruptured. The long-term rupture rate per 100 patient-year for unruptured intracranial aneurysms treated with endovascular therapy was 0.48 (95% CI, 0.45-0.51). Retreatment was carried out in 236 (4.9%) of these 4842 patients. LIMITATIONS: A limitation of the study is that a lack of systematic nature of follow-up and mean follow-up duration of 3.2 years are not sufficient to make general recommendations about aneurysm followup paradigms. CONCLUSIONS: Given a 5% retreatment rate, postcoil embolization spontaneous rupture of previously unruptured, small- and medium-sized, well-treated aneurysms is exceedingly rare.

RESUMEN

OBJECTIVE: The aim was to evaluate renal related outcomes in patients who had incorporation of a small (<4.0 mm) renal artery (RA) during fenestrated-branched endovascular aortic repair (F-BEVAR). METHODS: A total of 215 consecutive patients enrolled in a prospective F-BEVAR trial were reviewed. Computed tomography angiography centreline of flow reconstruction was used to measure mean RA diameter. Patients who had at least one <4.0 mm main or accessory RA incorporated by fenestration or directional branch (study group) were compared with patients who had incorporation of two ≥5.0 mm RAs (control group). Endpoints were technical success of RA incorporation, RA rupture and kidney loss, primary and secondary RA patency, RA branch instability and re-interventions, and renal function deterioration. RESULTS: Twenty-four patients with 28 <4.0 mm RAs (16 accessory and 12 main RAs) were compared with 144 patients with 288 ≥5.0 mm incorporated RAs. Study group patients were significantly younger than controls (72 ± 8 vs. 75 ± 8 years, p = .04) and more often females (46% vs. 21%, p = .018); there were no differences in cardiovascular risk factors and aneurysm extent. Technical success was 92% for <4.0 mm and 99% for ≥5.0 mm RA incorporation (p = .05). Inadvertent RA rupture occurred in three patients in the study group (13%) and in one (1%) in the control group (p = .009) resulting in kidney loss in two study group patients (8%) and one (1%) control group patient (p = .05). At one year, primary patency was 79 ± 9% vs. 94 ± 1% (p < .001) and secondary patency was 84 ± 8% vs. 97 ± 1% (p < .001) for study vs. control group; freedom from branch instability was 79 ± 9% vs. 93 ± 2% (p = .005), respectively. There were no differences in re-intervention rates and renal function deterioration between the groups. The mean follow up time was 21 ± 14 months. CONCLUSION: Incorporation of <4.0 mm RAs during F-BEVAR is associated with lower technical success, higher risk of arterial disruption and kidney loss, and lower patency rates at one year.

RESUMEN

BACKGROUND: The study aims to assess characteristics and outcomes of patients suffering a mechanical complication (MC) after ST-segment elevation myocardial infarction (STEMI) in a contemporary cohort of patients in the percutaneous coronary intervention era. METHODS AND RESULTS: This retrospective single-center cohort study encompasses 2508 patients admitted with STEMI between March 9, 2009 and June 30, 2014. A total of 26 patients (1.1%) suffered a mechanical complication: ventricular septal rupture (VSR) in 17, ventricular free wall rupture (VFWR) in 2, a combination of VSD and VFWR in 2, and papillary muscle rupture (PMR) in 5 patients. Older age (74.5 ± 10.4 years versus 63.9 ± 13.1 years, p < 0.001), female sex (42.3% versus 23.3%, p = 0.034), and a longer latency period between symptom onset and angiography (> 24h: 42.3% versus 16.2%, p = 0.002) were more frequent among patients with MC as compared to patients without MC. The majority of MC patients had multivessel disease (77%) and presented in cardiogenic shock (Killip class IV: 73.1%). Nine patients (7 VSR, 2 VFWR & VSR) were treated conservatively and died. Out of the remaining 10 VSR patients, four underwent surgery, three underwent implantation of an occluder device, and another three patients had surgical repair following occluder device implantation. All patients with isolated VFWR and PMR underwent emergency surgery. At 30 days, mortality for VSR, VFWR, VFWR & VSR and PMR amounted to 71%, 50%, 100% and 0%, respectively. CONCLUSIONS: Despite advances in the management of STEMI patients, mortality of mechanical complications stays considerable in this contemporary cohort. Older age, female sex, and a prolonged latency period between symptom onset and angiography are associated with the occurrence of these complications.

RESUMEN

In gastrointestinal stromal tumors (GISTs), rupture is a high-risk feature; however, "tumor rupture" is inconsistently defined, and its prognostic value remains controversial.Six hundred ninety-one patients undergoing surgery for primary nonmetastatic GISTs from 2003 to 2015 at our institution were enrolled. The strict definitions of "tumor rupture" according to the Kinki GIST Study Group (KGSG) were used.The median follow-up time was 64 months. The 5-year recurrence-free survival (RFS) and overall survival (OS) rates in the entire group were 79.3% and 84.1%, respectively. According to the KGSG's definition, tumor rupture occurred only in 24 (3.5%) of 691 patients. For all 691 patients, multivariable analysis showed that tumor rupture, according to KGSG's definition, is one of the independently prognostic factors for both RFS and OS. Twenty-four patients with tumor rupture were further analyzed. Receiving IM for more than 3 years was significantly associated with improved RFS and OS in GISTs patients with tumor rupture.Tumor rupture according to KGSG's definition was an independent predictive factor associated with GIST patient prognosis. More importantly, for GISTs with tumor rupture according to the KGSG's strict definition, receiving IM treatment for ≥3 years should be considered.

RESUMEN

A retinal pigment epithelial (RPE) tear is a well-known complication of retinal pigment epithelial detachments (PED) and may cause a significant visual impairment. The most common cause is a vascularized PED in patients with exudative age-related macular degeneration (AMD). The development of diagnostic imaging techniques brings us closer to the etiology and pathophysiological mechanisms of this entity, offering us new strategies for treatment and follow-up. The advent of intravitreal antiangiogenic treatment (anti-VEGF) has led to an increase in the number of reported cases of RPE tears, which are an important vision-limiting factor during treatment. However, RPE tears may occur spontaneously or as a consequence of thermal laser treatment, photodynamic therapy or anti-VEGF therapy. It is accepted that the mechanism of RPE tears is multifactorial. The optimization of the functional outcome of this complication has been described with continuous treatment with antiangiogenic drugs. The goal of the present review is to evaluate the incidence, risk factors and treatment of RPE tears.

RESUMEN

BACKGROUND: Many studies have investigated the association between time interval and incidence of complicated appendicitis and post-operative surgical site infection (SSI), but the results are controversial. METHODS: A systematic search of the electronic databases identified studies that investigated the association of appendectomy delay with complicated appendicitis and SSI among patients with acute appendicitis. Qualitative and quantitative meta-analysis of the results was conducted. RESULTS: Twenty-one studies were included in the final analysis. Meta-analysis showed no significant difference in complicated appendicitis incidence between patients in the 6-12 h, > 12 and < 6 h groups (OR 1.07, 95% CI 0.89-1.30, p = 0.47; OR 1.04, 95% CI 0.88-1.22, p = 0.64). Comparison of the 6-12 h category with the < 6 h category of in-hospital delay revealed significant associations between longer in-hospital delay and increased risk of post-operative SSI (OR 1.40, 95% CI 1.11-1.77, p = 0.004). Patients in the 24-48 h category had 1.99- and 1.84-fold (p < 0.05) higher odds of developing complicated appendicitis compared to patients in the < 24 h category for pre-hospital delay and total delay, respectively (OR 1.99, 95% CI 1.35-2.94, p = 0.0006; OR 1.84, 95% CI 1.05-3.21, p = 0.03). When pre-hospital and total delay time extended to more than 48 h, the odds of risk increased 4.62- and 7.57-fold, respectively (OR 4.62, 95% CI 2.99-7.13, p < 0.00001; OR 7.57, 95% CI 6.14-9.35, p = < 0.00001). CONCLUSION: Complicated appendicitis incidence was associated with overall elapsed time from symptom onset to admission or operation; short appendectomy in-hospital delay did not increase the risk of complicated appendicitis but was associated with a slightly increased risk of SSI. Prompt surgical intervention is warranted to avoid additional morbidity, enabling quicker recovery in this population.

RESUMEN

INTRODUCTION: Cardiovascular complications in patients with subarachnoid hemorrhage are considered to be a neurally mediated process rather than a manifestation of coronary artery disease. AIM: The aim of study is to show the incidence and type cardiac complications after traumatic and spontaneous SAH. PATIENTS AND METHODS: The study had prospective character in which included 104 patients, with diagnosed subarachnoid hemorrhage (SAH), in the period from 2014 to 2017. Two groups of patients were formed. Group I: patients with SAH caused by the rupture of a brain aneurysm. Group II: patients with SAH after traumatic brain injury. RESULTS: Electrocardiogram (ECG) abnormalities was predominant after traumatic brain injury 74 %, with statistically significant difference atrial fibrillation 42.5 % (p = 0.043) and sinus bradycardia 31.4 % (p = 0.05). Hypertension are predominant in patients with spontaneous SAH with statistically significant difference (15 (27.7%) vs 36 (72%) p=0.034) and hypotension in group II (10 (18.5%) vs 2 (4%) p = 0.021 ) with traumatic SAH patients. The time in Intensive Care Unit (ICU) for traumatic SAH group was 6.1 ± 5.2 days and 3.9 ± 1.16 for spontaneous SAH group with statistical significance (p = 0.046). Respiratory support time was longer in traumatic SAH group (39.4 ± 23.44 vs. 15.66 ± 22.78) with p = 0.043. CONCLUSION: Cardiac dysfunction in patients with subarachnoid hemorrhage are considered to be a neurally mediated process rather than a manifestation of coronary artery disease. Early treatment of cerebral injury could be reduce incidence of cardiac complications after traumatic brain injury. Cardiac dysfunction in patients with SAH is still very high, despite substantial qualitative progress in their treatment.

RESUMEN

PURPOSE: To evaluate the effects of progressive hydrocephalus on the developing brain in a cohort of fetuses diagnosed with congenital aqueduct stenosis by comparing prenatal magnetic resonance imaging and postnatal imaging. METHODS: This IRB approved single center retrospective review of prenatally diagnosed children with congenital aqueduct stenosis interrogated changes in the brain between prenatal and postnatal imaging and analyzed statistics using SAS software package version 9.3. RESULTS: Thirty fetuses imaged at a mean gestational age of 26 weeks had aqueduct obstruction confirmed by postnatal imaging. Progressive hydrocephalus required shunting in all but one patient (97%). Those patients with increasing hydrocephalus showed increase in ventricular rupture (60%), loss of septal leaflets (47%), and reduction in white matter and corpus callosum volume (43%). Cerebellar ectopia developed in 27% with 6% meeting the criteria for Chiari I malformation. CONCLUSION: Hydrocephalus in the fetus results in enlarging ventricular rupture, loss of the septum pellucidum leaflets, volume reduction of brain parenchyma including corpus callosum, and risk for Chiari I anomaly. Given advances in fetal surgery and imaging in the last 3 decades, there may be cause to revisit the idea of in utero cerebral spinal fluid diversion as a means to potentially ameliorate progressive loss of the developing brain.

RESUMEN

BACKGROUND: Spontaneous ruptured aortic plaques (SRAP), which might cause atheromatous embolization, are thought to be mainly iatrogenic and have not been observed directly. OBJECTIVES: The purpose of this study was to clarify the incidence, types, and dimensions of SRAP using angioscopy. METHODS: In a cross-sectional study, 324 consecutive patients diagnosed with or suspected of having coronary artery disease were subjected to intra-aortic scans with nonobstructive angioscopy. Samples of SRAP were taken from the aorta. The dimensions of cholesterol crystals of atheromatous materials were measured with a polarizing microscope and compared with those of the ghost images of cholesterol crystals. RESULTS: SRAP were detected in 262 patients (80.9%); 120 of 262 patients had ruptured aortic plaques below the diaphragmatic level. Samples were successfully obtained from 96 patients. The detected numbers of atheromatous material, fibrin, macrophage, and calcification were 237 (49.1%), 244 (50.6%), 111 (23.0%), and 127 (26.3%) out of 482 samples, respectively. The median lengths and widths of the sampled plaques were 254 µm (interquartile range [IQR]: 100 to 685 µm) and 148 µm (IQR: 535 to 423.5 µm), respectively. The lengths and widths of the cholesterol crystals isolated from atheromatous materials were 40 µm (IQR: 32.7 to 53.7 µm), and 30 µm (IQR: 23 to 38 µm), respectively, compared with the respective dimensions of the ghost images of 86 µm (IQR: 53 to 119) and 13 µm (IQR: 7 to 18 µm). No embolic symptoms were observed within 24 h of general care via cardiac catheterization. CONCLUSIONS: SRAP are commonly scattered, and their dimensions were smaller than previously recognized.
