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.
Objective: Israeli hospitals were confronted with a major national outbreak of carbapenemase-producing Enterobacterales (CPE) starting in 2006, caused predominantly by monoclonal Klebsiella pneumoniae carbapenemase (KPC)-producing Klebsiella pneumoniae. Our hospital, Rambam Health Care Campus (RHCC), was one of the medical centers affected by this outbreak. We aimed to investigate the changing epidemiology of CPE at RHCC since 2006.
Methods: This was a retrospective observational cohort study performed in Northern Israel (Haifa) at RHCC, which is a primary tertiary acute care academic hospital. The study included all patients who had acquired CPE at RHCC between January 2005 and December 2020.
Results: The proportion of patients infected with K. pneumoniae dropped from 100% of all CPE in the first years to 28% (37/134) in 2020. In 2014, the carbapenemase in 94% of all CPE patients (89/95) was KPC. This decreased to 56% in 2020, while New Delhi metallo-β-lactamase (NDM) and OXA-48 carbapenemases increased from 4% and 2% to 29% (39/134) and 12.7% (17/134) of CPE, respectively.
Conclusions: The CPE epidemic evolved from KPC-producing K. pneumoniae to involve different Enterobacterales and carbapenemases. Our results are a microcosm of the current global epidemiology attesting to globalization in bacteriology. The results have implications for infection control and antibiotic treatment of CPE infections.
Objective: Congenital nasopharyngeal masses (CNMs) are rare. Presenting symptoms vary, and the differential diagnoses cover a wide spectrum of possibilities. As it is uncommon, most examples discussed in literature are described as case reports or series. Guidelines on CNM patient management do not exist. In this study, we present two (2) cases of neonates with CNMs that were encountered at our tertiary center. Additionally, to best elaborate a comprehensive, case-based approach to CNM management, we offer an up-to-date, diagnosis-to-treatment review of current literature.
Methods: Case series and systematic literature review.
Results: Twenty-eight (28) studies are included since January 2000 to October 2021, with a total of 41 cases. Most common diagnosis was teratoma (78%). Female-to-male ratio was 2.5:1. Twenty percent of cases presented prenatally with polyhydramnios or elevated alpha-fetoprotein. Postnatally, the presenting symptoms most frequently encountered were respiratory distress (78%), oral mass (52%), and feeding difficulties (29%). Seventy-five percent of affected newborns showed symptoms within the first 24 hours of life. Forty percent of cases had comorbidities, especially in the head and neck region.
Conclusions: Congenital nasopharyngeal masses can be detected antenatally, or symptomatically immediately after birth. Airway protection is a cornerstone in the management. Selecting the right imaging
modality and convening a multidisciplinary team meeting are important toward the planning of next steps/therapeutic approach. Typically, a transnasal or transoral surgical approach will be deemed sufficient to address the problem, with a good overall prognosis.
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.
Objective: Cirrhotic cardiomyopathy (CCM) is associated with increased morbidity and mortality in patients with liver cirrhosis. Yet, it remains an under-diagnosed entity. Further, its relation to the severity of cirrhosis is contradictory. We conducted this study on an Indian population to determine the cardiac dysfunctions in cirrhosis of the liver and correlations with etiologies and cirrhosis severity.
Methods: This study enrolled patients with diagnosed liver cirrhosis without any cardiac disease or conditions affecting cardiac function. All participants were evaluated clinically, electrocardiographically, and echocardiographically. Cirrhosis severity was assessed by scores from the Model for End-stage Liver Disease (MELD) and Child–Turcotte–Pugh (CTP) tests. Cirrhotic cardiomyopathy was defined as diastolic dysfunction and/or systolic dysfunction with QT prolongation.
Results: Ninety-six patients were evaluated, and CTP-A stage of cirrhosis was found in 23 (24%), CTP-B in 42 (43.8%), and CTP-C in 31 (32.3%) cases. Systolic dysfunction was most frequent (P=0.014), and left ventricular ejection fraction was significantly reduced (P=0.001) in CTP-C stage of cirrhosis. Cirrhotic cardiomyopathy was found in 39.6% (n=38) of patients; CCM patients had significantly higher CTP scores (9.6±2.6 versus 8.3±2.3, P=0.012) as well as MELD scores (19.72±4.9 versus 17.41±4.1, P=0.015) in comparison to patients without CCM.
Conclusion: Cirrhotic cardiomyopathy has a positive relationship with the severity of cirrhosis. Systolic function declines with the severity of cirrhosis, and overt systolic dysfunction can be present, particularly in the advanced stage of cirrhosis of the liver.
The Joles Jewish Hospital in Haarlem (a small city in the Netherlands) was established in 1930 to provide a Jewish milieu for local patients. Mozes Joles, a wealthy Jewish businessman, bequeathed his fortune to the Haarlem Jewish community to accomplish this objective, and its spiritual leader, Rabbi Simon Philip de Vries, was the driving force in successfully achieving this goal. The Joles Hospital was forcibly closed by the Nazis in 1943, and the postwar leadership of the Haarlem Jewish community decided not to reopen it. Instead, they used the Joles inheritance to build old age homes in both Haifa, Israel, and Haarlem, thus ensuring a Jewish environment for elderly care in both locales. The realization of one man’s charitable act bettered the lives of both ill and elderly individuals.
Background: Blunt traumatic brain injury (bTBI) and uncontrolled hemorrhagic shock (UCHS) are common causes of mortality in polytrauma. We studied the influence of fresh frozen plasma (FFP) resuscitation in a rat model with both bTBI and UCHS before achieving hemorrhage control.
Methods: The bTBI was induced by an external weight drop (200 g) onto the bare skull of anesthetized male Lewis (Lew/SdNHsd) rats; UCHS was induced by resection of two-thirds of the rats’ tails. Fifteen minutes following trauma, bTBI+UCHS rats underwent resuscitation with FFP or lactated Ringer’s solution (LR). Eight groups were evaluated: (1) Sham; (2) bTBI; (3) UCHS; (4) UCHS+FFP; (5) UCHS+LR; (6) bTBI+UCHS; (7) bTBI+UCHS+FFP; and (8) bTBI+UCHS+LR. Bleeding volume, hematocrit, lactate, mean arterial pressure (MAP), heart rate, and mortality were measured.
Results: The study included 97 rats that survived the immediate trauma. Mean blood loss up to the start of resuscitation was similar among UCHS only and bTBI+UCHS rats (P=0.361). Following resuscitation, bleeding was more extensive in bTBI+UCHS+FFP rats (5.2 mL, 95% confidence interval [CI] 3.7, 6.6) than in bTBI+UCHS+LR rats (2.5 mL, 95% CI 1.2, 3.8) and bTBI+UCHS rats (1.9 mL, 95% CI -0.2, 3.9) (P=0.005). Similarly, non-significant increases in blood loss were observed in UCHS+FFP rats (P=0.254). Overall mortality increased if bleeding was above 4.5 mL (92.3% versus 8%; P<0.001). Mortality was 83.3% (10/12) in bTBI+UCHS+FFP rats, 41.7% (5/12) in bTBI+UCHS+LR rats, and 64.3% (9/14) in bTBI+UCHS rats.
Conclusion: The bTBI did not exacerbate bleeding in rats undergoing UCHS. Compared to LR, FFP resuscitation was associated with a significantly increased blood loss in bTBI+UCHS rats.
During the past few years, thousands of articles have been published concerning medical cannabis useage. Unfortunately, most publications are case studies or small and poorly designed research projects. In attempting to understand the reasons behind this situation, the obstacles impeding the use of medical cannabis and related research merit more in-depth examination. This editorial looks at some of the issues.
Because of rising antivaccine activism and some key global policy missteps, we risk eroding more than 70 years of global health gains. This is occurring through an enabled and empowered antiscience ecosystem, with anti-Semitism and the targeting of Jewish biomedical scientists at its core.
Objective: In patients with acute hepatic porphyria (AHP), prolonged fasting is a known trigger of AHP attacks. Despite this, some Jewish AHP patients—mainly hereditary coproporphyria (HCP) and variegate porphyria (VP) patients—fast for 25 consecutive hours during the traditional Jewish holy day known as Yom Kippur. In this study, we evaluated the effect of the fast on these patients.
Methods: A retrospective study and survey of AHP patients in Israel was carried out. Patients were asked whether they have fasted and whether any symptoms were induced by this fast. Patients’ medical records were reviewed for an emergency department (ED) visit following YK between 2007 and 2019. Only 3 acute intermittent porphyria (AIP) patients reported fasting; they were excluded from analysis.
Results: A total of 21 HCP patients and 40 VP patients completed the survey; 30 quiescent patients reported they fast, while 31 did not fast. The majority of fasting patients (96.67%) reported no symptoms following a fast. We found no statistically significant association between ED visits 1 week (0.26% in both fasting and non-fasting patients) or 1 month (2.1% visits in non-fasting versus 0.78% in fasting patients) following Yom Kippur. Of the symptomatic ED visits following a fast, none were defined as severe attacks.
Conclusion: A 25-hour fast in stable HCP and VP patients did not increase the risk of an acute attack and can probably be regarded as safe.
