Patients have an ongoing unmet need for effective therapies that reverse the cellular and functional damage associated with heart damage and disease. The discovery that ~1%–2% of adult cardiomyocytes turn over per year provided the impetus for treatments that stimulate endogenous repair mechanisms that augment this rate. Preclinical and clinical studies provide evidence that cell-based therapy meets these therapeutic criteria. Recent and ongoing studies are focused on determining which cell type(s) works best for specific patient population(s) and the mechanism(s) by which these cells promote repair. Here we review clinical and preclinical stem cell studies and anticipate future directions of regenerative medicine for heart disease.
The surgical management of cerebral and skull base lesions has evolved greatly in the last few decades. Still, a complete resection of lesions abutting critical neurovascular structures carries significant morbidity. Stereotactic radiosurgery (SRS) has emerged as an increasingly accepted treatment option. Minimally invasive, SRS results in excellent tumor control and low complication rates in patients with moderate-size tumors. The management of large cerebral and skull base tumors remains a formidable challenge. In such large tumors, radical surgical extirpation offers a significantly higher risk of neurological deficit, and SRS alone cannot be used because of the elevated incidence of radiation-induced complications known to be associated with large-volume tumors. With increasing treatment volumes, SRS-associated tumor control rates decrease and complication rates increase. Planned subtotal resection (STR) with adjuvant SRS (adaptive hybrid surgery [AHS]) has gained increasing interest in recent years as a multimodal approach. In AHS, a planned STR (aimed at decreasing surgical morbidity) followed by SRS to a preplanned residual tumor aids in harnessing advantages offered by both approaches. Although intuitive and reasonable, this paradigm shift from maximal resection at all cost has not been adopted widely. Combining open micro¬surgery with SRS requires a good understanding of both surgical and SRS modalities and their respective safety–efficacy features. We present a review and discussion on AHS as a modern, multidisciplinary treatment approach. Available data and views are discussed for vestibular schwannoma (VS) as a sample tumor. Other indications for AHS are mentioned in brief.
Dear Friends and Colleagues,
Since its launch in 2010, Rambam Maimonides Medical Journal (RMMJ) has focused on its mission of expanding the knowledge base of medicine, science, humanity, and ethics throughout the world, flavored by the salt of the 850-year-old philosophy of Rabbi Moshe Ben Maimon—known by the Hebrew acronym “RAMBAM” or, more commonly, as Maimonides.
Objective: Extracorporeal membrane oxygenation is used to bypass the cardiopulmonary system in a severe heart or/and lung failure, mainly in intractable conditions where all other therapy options fail or are unfeasible. Extracorporeal membrane oxygenation (ECMO) is a well-established therapeutic option in such circumstances for neonatal, pediatric, and adult patients. Managing a patient with ECMO requires dedicated and specific management. The importance and necessity of this essential technology in life-threatening cardio-respiratory rescue prompted Rambam Health Care Campus to implement it and make it available as a service to the population in northern Israel. This article includes a brief review of extracorporeal life support and a report of our single-center experience since the establishment of the service.
Methods: The ECMO unit was established in 2014 under the responsibility of the Cardiac Surgery Department. The ECMO service was initiated by a well-planned program with consideration of all aspects including economics, education and training, the specialist team and equipment needed, strategies for medication, and ethical challenges.
Results: Between February 2014 and May 2018, 65 patients were treated with ECMO; 43 patients received veno-arterial ECMO for cardiac support (66%), while 22 received veno-venous ECMO for respiratory support (34%). The in-hospital mortality was 56%.
Conclusions: Extracorporeal membrane oxygenation is an effective therapy that is constantly growing in use and provides a therapy that can replace previous options. To establish such a service requires a planned program and concerted effort. Our single-center experience presented a good learning curve and showed the feasibility as well as the efficacy of the ECMO procedure in life-threatening conditions.
Introduction: Catch-up growth (CUG) in small-for-gestational age (SGA) infants is essential for their overall development. Knowledge about the factors influencing CUG might be critical in their effective management. Hence this study was performed with the aim of identifying factors that may influence CUG in SGA infants.
Methods: Asymmetrical SGA infants born at term were included in the study as per defined criteria, and their demographic details were recorded. Anthropometric data, feeding practice details, and intercurrent illnesses data were collected on follow-up at 6 weeks, 6 months, and 12–15 months of age. Catch-up growth weight was defined as improvement of weight to the normal range of -2 to +2 weight-for-age Z score (WAZ). Analysis was carried out using SPSS Expand 17 software. Chi-square test was used to find association between variables. Logistic regression analysis was used to measure effect. A P value of less than 0.05 was taken as significant.
Results: Out of 324 SGA infants born at term, 119 completed 12–15-month follow-up, of which 69.7% had achieved CUG weight. Exclusive breastfeeding >4 months, continued breastfeeding until 12–15 months, and absence of diarrheal episodes were positively associated with CUG. Pregnancy-induced hypertension, gestational diabetes, and maternal overweight/obesity were negatively associated with CUG. Maternal education status, conception age, gravida status, mode of delivery, vitamin D and iron supplementation, and intercurrent respiratory infections were not associated with CUG. On multivariate analysis, continued breastfeeding and absence of diarrheal episodes were independent factors associated with CUG.
Conclusion: Breastfeeding practice, especially continued breastfeeding, and the absence of diarrheal illness are the key determinants for achieving CUG weight in term SGA infants, particularly in settings where resources are limited.
Background: Eosinophils constitute 1%–5% of peripheral blood leukocytes, less in the presence of acute infections (referred to as eosinopenia). Studies indicate that eosinopenia can be used as a prognostic predictor for chronic obstructive pulmonary disease exacerbation, sepsis, or acute myocardial infarction disease. There are only a few studies about predicting mortality in emergency departments and intensive care units (ICUs). Prognostic studies about patients in ICUs are generally carried out using different scoring systems. We aimed to analyze if the eosinophil count can estimate the prognosis among non-traumatic patients who underwent cardiopulmonary resuscitation and were hospitalized in ICU thereafter.
Methods: The data were evaluated of 865 non-traumatic adult patients (>18 years of age) who were admitted with cardiopulmonary arrest or developed cardiopulmonary arrest during clinical follow-ups. Admission venous blood sample tests, complete blood count, and biochemical laboratory results were recorded. Arterial blood gas results were also evaluated. The mean results of the recorded laboratory results were compared between the surviving and non-surviving patients groups.
Results: There was a significant difference between the two groups in regard to platelet, eosinophil count, pH, PaO2, SaO2, and HCO3- (P<0.001 for all). In the multiple linear regression analysis, eosinophil counts were found to be an independent factor (odds ratio=0.03, 95% confidence interval 0.33–0.56, P<0.001) associated with the mortality after cardiopulmonary resuscitation.
Conclusion: Because admission eosinophil counts can be measured easily, they are inexpensive biomarkers that can be used for predicting the prognosis among the patients who have return of spontaneous circulation and are treated in ICUs.
Effective chest compressions have been proven to be a key element in a successful cardiopulmonary resuscitation (CPR). However, unintended injuries have been described in the medical literature for decades, including major intrathoracic injuries. We present a case of an 80-year-old man after a successful CPR who was later diagnosed with deep epicardial laceration as a result of effective chest compressions.
Introduction: Microvasculopathy is characterized by progressive structural and functional damage to the microvessels and plays a key role in the pathogenesis of various connective tissue diseases (CTD). Nailfold videocapillaroscopy is an optimal and validated method for analysis of microvascular abnormalities and is able to differentiate secondary Raynaud’s phenomenon (RP) of CTD from primary RP and healthy subjects.
Aim: To assess and analyze nailfold capillaroscopic findings in Indian subjects with secondary Raynaud and to compare with findings in healthy subjects.
Methods: A total of 62 study participants including cases and controls underwent nailfold videocapil-laroscopy. Capillary loop length, capillary width, capillary density, presence/absence of tortuosity, giant loops, neoangiogenesis, microhemorrhages, and avascular areas were the parameters studied.
Results: All the quantitative and qualitative parameters studied were significantly associated with second¬ary RP. Mean loop length in cases of connective tissue diseases was significantly less than in the controls (225.74 µm versus 282.97 µm) (P=0.002). Capillary density was also reduced significantly in the cases as compared to the controls (4.6 versus 7.39/mm) (P<0.01), whereas it was markedly decreased in systemic sclerosis (SSc) and mixed connective tissue diseases (MCTD), and near normal in systemic lupus erythematosus (SLE). Tortuosity was the most frequent (77.4%) qualitative parameter. Scleroderma pattern was found in 62.5% of patients with SSc and in 60% with MCTD. Non-specific pattern was found in 80% of SLE cases and 50% of dermatomyositis cases.
Conclusion: Both quantitative and qualitative capillaroscopic changes are significantly associated with secondary RP. Scleroderma pattern was predominant in SSc and MCTD, whereas non-specific pattern was predominantly found in SLE and dermatomyositis.
Today, in the 21st century, most people are aware of the term genocide. However, few people are aware that this term only entered the English language in the 1940s, as a result of the dedicated work of a brilliant and successful man who deprived himself of a private family life so that he could be free to fight for his ideas. Although Raphael Lemkin was instrumental in the recognition of genocide by the United Nations, he died too early and was buried with no honor. This paper reviews the life and work of Raphael Lemkin, and his triumph in seeing genocide recognized as a crime.
Background: Patellar instability comprises a group of pathologies that allow the patella to move out of its trajectory within the trochlear groove during walking. Symptomatic patients who need surgery commonly undergo soft tissue procedures such as medial patellofemoral ligament repair to strengthen the ligaments that hold the patella in place. However, soft-tissue repairs may be insufficient in patients suffering from patellar maltracking, which is characterized by an unbalanced gliding of the patella within its route. In these patients, a different approach is advised. We aim to provide the mid-term clinical outcomes of the Fulkerson distal realignment operation in selected patients with non-traumatic patellar maltracking.
Methods: The clinical outcomes of the Fulkerson distal realignment operation performed in 22 knees of 21 patients were evaluated by a self-administered subjective International Knee Documentation Committee (IKDC) score and the Tegner–Lysholm knee scoring scale.
Results: Before surgery, the median IKDC score was 52, and the median Tegner–Lysholm score was 56. Following surgery (mean follow-up 48 months, range 24–156), the median IKDC and the Tegner–Lysholm scores were 67 and 88, respectively. The improvement was statistically significant (P=0.001 and P=0.002 for IKDC and Tegner–Lysholm scores, respectively). Associated procedures included patella microfracture due to grade III–IV cartilage lesion (International Cartilage Repair Society grading system) in four patients, retinacular releases in three patients, medial capsular augmentations in two patients, and medial patellofemoral ligament reconstruction in two patients. One patient with Ehlers–Danlos disease required excessive medialization of the tibial tuberosity. Surgery-related complications occurred in three patients.
Discussion: Surgical correction of patellar maltracking with Fulkerson distal realignment combined with associated procedures in individual patients was associated with an increase in subjective and functional clinical scores at medium-term follow-up. Particular attention should address pathologies associated with patellar maltracking and managed accordingly.
Level of evidence: 4c (case series).
