Independent Risk Factors for Thromboembolic Events in High-Risk Patients With Takotsubo Cardiomyopathy.

Takotsubo cardiomyopathy (TCM) is characteristically associated with left ventricular apical ballooning and regional wall motion abnormalities that predispose to the formation of left ventricular (LV) thrombi and subsequent thromboembolic events (VTE). There is limited data about the risk factors of developing stroke in the absence of LV thrombi in patients with TCM. Identify risk factors that predispose patients with TCM to develop VTE and stroke. We retrospectively reviewed all patients admitted with a primary diagnosis of stress induced or Takotsubo cardiomyopathy at a large tertiary care center from 2005 to 2019. Patients who met the echocardiographic criteria of TCM, had resolution of WMA on repeat echocardiogram, did not have coronary artery disease if angiography was performed and survived for > 3 months after index presentation were included in the analysis. Patients were followed for up to a period of 1 year. Multivariate analysis was performed to identify predictors of thromboembolism. Among the 400 patients who presented with TCM, 146 patients were included in the analysis. A total of 13 patients (8.9%) had documented thromboembolic events. Patients with VTE more often had Atrial fibrillation (30.8% vs 6.8%, P = 0.018), higher LV mass (224.5g vs 184g, P = 0.04), lower EF on presentation (31.5% vs 40%, P = 0.011) and were less likely to have undergone coronary angiography following diagnosis (23.1% vs 54.9%, P = 0.04). On multivariate analysis, atrial fibrillation (OR 9.15, CI 1.15-72.70) and low ejection fraction on admission (OR 0.88, CI 0.81-0.97) were independent risk factors for the development of VTE. Atrial fibrillation and low ejection fraction on presentation were associated with higher risk of developing thromboembolic events in patients with TCM.

July effect in clinical outcomes of esophagogastroduodenoscopy performed at teaching hospitals in the United States.

Background: Esophagogastroduodenoscopy (EGD) is a common procedure used for both diagnosis and treatment, but carries risks such as bleeding and perforation. The "July effect"-described as increased complication rates during the transition of new trainees-has been studied in other procedures, but has not been thoroughly evaluated for EGD. Methods: We used the National Inpatient Sample database for 2016 to 2018 to compare outcomes in EGD performed between July to September and April to June. Results: Approximately 0.91 million patients in the study received EGD between July to September (49.35%) and April to June (50.65%), with no significant differences between the two groups in terms of age, gender, race, income, or insurance status. Of the 911,235 patients, 19,280 died during the study period following EGD, 2.14% (July-September) vs 1.95% (April-June), with an adjusted odds ratio of 1.09 (P < 0.01). The adjusted total hospitalization charge was $2052 higher in July-September ($81,597) vs April to June ($79,023) (P < 0.005). The mean length of stay was 6.8 days (July-September) vs 6.6 days (April-June) (P < 0.001). Conclusions: The results of this study are reassuring as the July effect on inpatient outcomes for EGDs was not significantly different according to our study. We recommend seeking prompt treatment and improving new trainee training and interspecialty communication for better patient outcomes.

Non-Convulsive Status Epilepticus in Hepatic Encephalopathy: A Case Series and Review of the Literature.

Hepatic encephalopathy is a common complication in chronic liver disease and cirrhosis. Here we describe two patients with hepatic encephalopathy who did not respond to standard empiric treatment and were found to have non-convulsive status epilepticus. Both patients improved with antiepileptic therapy. Non-convulsive status epilepticus should be considered in the differential diagnosis of patients with suspected hepatic encephalopathy who do not respond to empiric treatment. LEARNING POINTS: Non-convulsive status epilepticus (NCSE) is a rare complication of hepatic encephalopathy (HE).Clinical evaluation should be used to rule out different causes of altered mental status in patients with chronic liver disease.Consider EEG to diagnose NCSE in patients with suspected HE not responding to empiric treatment.

The first study of epidemiology of adolescent idiopathic scoliosis shows lower prevalence in females of Jammu and Kashmir, India.

AIS is a heterogeneous 3D spinal deformity with Cobb angle ≥10°. It affects children in the age group of 10-16 years globally with 2-3% prevalence and significant female predominance. The exact etiology of AIS is not known however, it is supposed to be associated with factors such as anthropometric, metabolic, neuromuscular abnormalities and genetics. OBJECTIVES: To determine the prevalence of AIS and association of anthropometric factors with AIS in the studied population group. METHODOLOGY: Scoliosis screening of 9,500 individuals was carried out at different educational institutions of Jammu region in Jammu and Kashmir, India using a scoliosis-meter. The subjects were later examined radiologically. RESULTS: In population of the region, AIS was most prevalent among all types of scoliosis with overall prevalence of 0.61%. The prevalence was observed to be lower in females (0.31%) than males (0.88%). Based on angle of trunk rotation (ATR), lumbar curves were more prevalent than thoracic curves. Average Cobb angle in males and females were 24.9° and 22.6°, respectively. BMI showed significant association with AIS in the age group of 12-16 years (P value =0.028). Furthermore, height was significantly associated with AIS in the overall screened population (P-value =0.029). CONCLUSIONS: The AIS patients in the Jammu region of India have unique clinical features. In contrast to the global prevalence data, the prevalence of AIS in females in the region was less in comparison to males. Based on epidemiological literature and our findings, we hypothesized that genetic factors might be a major contributor in the AIS pathogenesis along with other confounding factors such as height, BMI, ethnicity, etc.

Determination of Non-Recrystallization Temperature for Niobium Microalloyed Steel.

In the present investigation, the non-recrystallization temperature (TNR) of niobium-microalloyed steel is determined to plan rolling schedules for obtaining the desired properties of steel. The value of TNR is based on both alloying elements and deformation parameters. In the literature, TNR equations have been developed and utilized. However, each equation has certain limitations which constrain its applicability. This study was completed using laboratory-grade low-carbon Nb-microalloyed steels designed to meet the API X-70 specification. Nb- microalloyed steel is processed by the melting and casting process, and the composition is found by optical emission spectroscopy (OES). Multiple-hit deformation tests were carried out on a Gleeble® 3500 system in the standard pocket-jaw configuration to determine TNR. Cuboidal specimens (10 (L) × 20 (W) × 20 (T) mm3) were taken for compression test (multiple-hit deformation tests) in gleeble. Microstructure evolutions were carried out by using OM (optical microscopy) and SEM (scanning electron microscopy). The value of TNR determined for 0.1 wt.% niobium bearing microalloyed steel is ~ 951 °C. Nb- microalloyed steel rolled at TNR produce partially recrystallized grain with ferrite nucleation. Hence, to verify the TNR value, a rolling process is applied with the finishing rolling temperature near TNR (~951 °C). The microstructure is also revealed in the pancake shape, which confirms TNR.

Outcome of treatment of the mismanaged pediatric elbow trauma: a series of 73 cases.

PURPOSE: To analyze the outcome of the management of pediatric elbow trauma referred to our hospital after initial intervention by traditional bone setters. METHOD: Retrospective study of 73 patients, presenting to the hospital with a complication attributable to the initial mismanagement of their injuries. RESULTS: The mode of presentation was directly related to the type of initial intervention on the basis of which we were able to quantify bone setters into two groups. The first group using a rather rough method of trauma treatment involving the application of tight local bandages, massage and manipulation and a second group having a relatively less rough approach, applying splints to the injured extremity without tight bandages and manipulation. The result of treatment of these injuries was determined by the delay in presentation and the type of injury. CONCLUSION: This study highlights the importance of dealing with the unchecked and unsupervised practice of bone setting in the developing world. We believe that training these people on the pattern of traditional birth attendants can at the very least lower the occurrence, if not entirely eliminate the problem of mismanaged trauma in this part of the world.

Complications of paediatric elbow trauma treatment by traditional bonesetters.

This is a retrospective review of paediatric elbow trauma, which was initially treated by bonesetters and subsequently reported to the hospital for management. This paper describes the pattern of trauma and the complications of unscientific management. The report also recommends a basic training program for the bonesetters so as to make them aware of the potential complications involved in managing paediatric elbow trauma.

Deformity correction and massive lengthening on a centralized fibula with the Ilizarov technique.

Lengthening beyond 25% of the original segment length is an orthopaedic challenge. Substantial lengthening is fraught with complications such as joint contractures, refractures, nerve injuries and prolonged periods of consolidation. We report a case of massive lengthening in a 17-year-old boy in whom a 20 cm lengthening (57% lengthening) and complex deformity correction was performed on a centralized fibula using the Ilizarov technique, with an excellent result. A total of 17 months were taken to complete the process of lengthening and consolidation at a healing index of 0.85 months/cm. Besides a minor pin tract infection, there were no major complications. We believe that with meticulous pre operative planning and follow-up the extent of lengthening can be extended in cases of severe limb length discrepancy.

Neurological outcome following delayed fixation of unstable thoracolumbar spinal injuries with short segment posterior fixation.

OBJECTIVE: To evaluate the improvement in neurological deficit following late decompression and stabilization of the fractured thoracolumbar spine. METHODS: Between January 2001 and August 2004 neurological recovery in 120 thoracolumbar fractures was studied after posterior stabilization at the Hospital for Bone & Joint Surgery, Srinagar, India. There were 88 male and 32 female patients. Fall from a height, usually a tree, was the most common (90%) cause of injury. Seventy-six patients (63%) had neurologic deficit at the time of presentation. The unstable spine was fixed, between 4-18 days after trauma, by posterior short segment instrumentation (Steffee). Neurological recovery for the patients was recorded in the follow-up period. Frankel grade was used to assess the neurological status. The average follow-up period was 25 months (range 8-44 months), and average age was 34 years (18-54). RESULTS: There were 40 patients (30%) with an incomplete neurological deficit, namely, patients with Frankel grade B, C, and D. Two grades of improvement were found in 8 patients, and one grade improvement in 32 patients with incomplete lesion. Only one third of the patients with complete neuro deficit improved at the final follow-up. The overall result of the surgery for partial lesions was an improvement of at least one Frankel grade in all cases, but no improvement in most of the cases with complete lesion. CONCLUSION: This study demonstrates a clear relationship between the level of injury and Frankel grades, translational injuries are associated with a more severe neurologic grade, and surgical intervention appears to improve the neurological outcome, even when the intervention is inadvertently delayed (average 7.9 days).

Acute Myeloid Leukemia: Is That All There Is?

Acute myeloid leukemia (AML) is characterized by the clonal proliferation of malignant myeloid blast cells in the marrow along with impaired normal hematopoiesis. With an almost stagnant approach for the management of patients with AML in the last three decades, the main purpose of this paper is to increase our understanding of recent scientific advancements for the enhanced diagnosis and treatment of AML. Existing research data related to different approaches for a possible improvement in AML management has been collected and discussed. The identification of recurrently mutated genes, such as CCAAT-enhancer-binding proteins α (CEBPα), Fms-related tyrosine kinase 3 (FLT3), and nucleophosmin 1 (NPM1) along with the classic diagnostic karyotype has improved prognostic-risk stratification. Moreover, mutations affecting cellular metabolism like isocitrate dehydrogenase (IDH1), lysine-specific demethylase 1 (LSD 1), and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) have become a huge success by providing targets for novel therapeutic drugs. Checkpoint inhibitors (CPI) and vaccination against tumor-associated antigen are added options considered, which require further trials before their efficacy can be determined. An important tool in monitoring early response to therapy, minimal residual disease (MRD) assays can be further refined by including pretreatment parameters such as cytogenetic and molecular markers. Potential side effects and resistance to treatment remains a huge barrier in completely finding success against AML and work needs to be done to find combinations of immunotherapies to possibly reduce adaptive resistance by AML.

Metastatic Castration-Resistant Prostate Cancer Previously Treated With Docetaxel-Based Chemotherapy: Treatment Patterns From the PROXIMA Prospective Registry.

PURPOSE: There is a major clinical need to devise an optimal treatment sequence for the multiple therapy options available for patients with metastatic castration-resistant prostate cancer (mCRPC). In the absence of prospective clinical trials, sequencing information can be derived from large, real-world registry studies. PATIENTS AND METHODS: PROXIMA (Treatment Patterns in Patients With Metastatic Castration-Resistant Prostate Cancer Previously Treated With Docetaxel-Based Chemotherapy) is a large, global, prospective registry study evaluating real-world treatment patterns of patients with mCRPC who experience disease progression during or after docetaxel therapy. Patients were enrolled worldwide between 2011 and 2014. Treatments were determined by the treating physicians and recorded in categories of chemotherapy, hormonal therapy, targeted therapy, immunotherapy, and palliative therapy. Treatment sequencing patterns, response to treatment, and types of progression were recorded and analyzed. Progression-free survival and overall survival with different treatment modalities were analyzed using Kaplan-Meier method. RESULTS: Treatment patterns were evaluated in 903 patients. Therapy selection was influenced by region. Hormonal therapy (57.5%) and taxane chemotherapy (26.4%) were the most frequently administered first subsequent treatments after docetaxel. Tumor responses to first subsequent treatment were observed in 22.6% of evaluable patients. Overall survival and progression-free survival did not differ significantly across different treatment modalities. CONCLUSION: Identifying an optimal treatment sequence is vital for improving the care of patients with mCRPC. The PROXIMA registry provided a representative sample of global data on real-world treatment patterns for patients with mCRPC previously treated with docetaxel. These data can be used to devise optimal therapy sequences and inform treatment decisions.

A prospective single arm phase II study of dacarbazine and treosulfan as first-line therapy in metastatic uveal melanoma.

Uveal melanoma is relatively uncommon accounting for fewer than 5% of all melanoma cases. Localized tumours are curable by local therapy but a significant percentage of patients go on to have a relapse with metastatic disease. Uncertainty remains concerning the level of activity of dacarbazine in uveal melanoma as opposed to that in the cutaneous form. Recently, a possible role for treosulfan in uveal disease has been reported. A phase II study was therefore undertaken to assess the objective response rate of the combination of dacarbazine and treosulfan in previously untreated patients with metastatic uveal melanoma. All patients received dacarbazine 850 mg/m and treosulfan 8 g/m(2) every 21 days up to a maximum of six cycles. Fifteen patients enrolled in the study. As expected, the major toxicities were haematological (particularly thrombocytopaenia) but the treatment was generally well tolerated. No responses were seen; however, disease stabilization was achieved in two patients. Median progression free survival from the start of chemotherapy was 12 weeks and median overall survival was 30 weeks. This study, using the combination of dacarbazine and treosulfan, while well tolerated, did not confirm earlier reports suggesting treosulfan is active in uveal melanoma.

Primary intrathoracic goiter -a rare mediastinal tumor.

Primary intrathoracic goiter is a rare presentation of thyroid disease. Its removal usually necessitates thoracotomy or sternotomy. This patient having a primary intrathoracic goiter presented with posterior mediastinal mass that was removed through a right lateral thoracotomy.

Treatment of comminuted proximal humerus fractures with shoulder hemiarthroplasty in elderly patients.

This retrospective study was done to find out the outcome of hemiarthroplasty of the shoulder following comminuted proximal humeral fractures in 20 elderly patients. Their average age was 77.6 years. The average follow-up was 33 months. All patients were reviewed in the outpatient clinic using the Constant Score. The median Constant Score was 47.5. None of the patients had severe pain. Four had moderate and 16 had no or mild pain. Range of movement was not good. The activities of daily living were significantly reduced in patients with moderate shoulder pain. Sixteen patients (80%) were satisfied with the outcome of the management of their shoulder injury. Radiological assessment showed malrotation of the prosthesis and ectopic ossification in one patient each. Osteolysis around the greater tuberosity was noted with three isoelastic prostheses. Seven patients showed proximal migration of the prosthesis although there was no significant difference in functional results. Complications included fatal pulmonary embolism in one patient. Overall, hemiarthroplasty of the shoulder gave good pain relief but there was only moderate functional improvement.

Comparison of Nottingham Prognostic Index and Adjuvant Online prognostic tools in young women with breast cancer: review of a single-institution experience.

OBJECTIVE: Accurately predicting the prognosis of young patients with breast cancer (<40 years) is uncertain since the literature suggests they have a higher mortality and that age is an independent risk factor. In this cohort study we considered two prognostic tools; Nottingham Prognostic Index and Adjuvant Online (Adjuvant!), in a group of young patients, comparing their predicted prognosis with their actual survival. SETTING: North East England PARTICIPANTS: Data was prospectively collected from the breast unit at a Hospital in Grimsby between January 1998 and December 2007. A cohort of 102 young patients with primary breast cancer was identified and actual survival data was recorded. The Nottingham Prognostic Index and Adjuvant! scores were calculated and used to estimate 10-year survival probabilities. Pearson's correlation coefficient was used to demonstrate the association between the Nottingham Prognostic Index and Adjuvant! scores. A constant yearly hazard rate was assumed to generate 10-year cumulative survival curves using the Nottingham Prognostic Index and Adjuvant! predictions. RESULTS: Actual 10-year survival for the 92 patients who underwent potentially curative surgery for invasive cancer was 77.2% (CI 68.6% to 85.8%). There was no significant difference between the actual survival and the Nottingham Prognostic Index and Adjuvant! 10-year estimated survival, which was 77.3% (CI 74.4% to 80.2%) and 82.1% (CI 79.1% to 85.1%), respectively. The Nottingham Prognostic Index and Adjuvant! results demonstrated strong correlation and both predicted cumulative survival curves accurately reflected the actual survival in young patients. CONCLUSIONS: The Nottingham Prognostic Index and Adjuvant! are widely used to predict survival in patients with breast cancer. In this study no statistically significant difference was shown between the predicted prognosis and actual survival of a group of young patients with breast cancer.

Sequential maximum androgen blockade (MAB) in minimally symptomatic prostate cancer progressing after initial MAB: two case reports.

The management of castrate-resistant prostate cancer progressing after maximum androgen blockade (MAB) has evolved in the last decade with the development of several novel therapeutic options. However, the initial therapeutic strategy in these patients usually involves withdrawal of anti-androgen that can be associated with biochemical response in approximately 20% of patients. Notably, we have observed evidence of sustained biochemical response in two patients following second- and third-line MAB using rechallenge schedule of previously administered anti-androgen after latent interval. The possibility of response following sequential MAB using the same anti-androgen agent has not yet been reported.

The posterior to anterior controlled technique of percutaneous Achilles tenotomy in the correction of idiopathic clubfoot: a technical report.

Percutaneous tenotomy of the Achilles tendon is an integral part of the Ponseti technique of clubfoot correction. Although originally described by Ponseti as an office procedure that was performed under local anaesthesia, serious neurovascular complications that include iatrogenic injury to the lesser saphenous vein, the posterior tibial neurovascular bundle, the sural artery and pseudoaneurysm formation have been reported. We describe a new tenotomy technique, the posterior to anterior controlled technique, that may decrease the possibility of neurovascular damage, does not require exposure of the Achilles tendon and can be performed as an office procedure under local anaesthesia.
