Introduction: Myopia is a refractive disorder commonly diagnosed in childhood that follows a progressive course. It is considered a global epidemic with nearly 23% of the world’s population being diagnosed with this condition. Moreover, myopia is increasing in prevalence worldwide, demonstrated by studies in Asian and Western populations. This has important implications as myopic progression to high myopia is associated with significant morbidity and visual disability if left untreated. Of these treatments, the pharmacologic agent atropine has demonstrated the greatest efficacy in reducing myopia progression.Case report: This is a case report of an 11-year-old male treated with 0.01% atropine drops for myopia progression that developed new-onset seizures. The seizures were characterized as benign epilepsy with central temporal spikes and ceased when drops were discontinued. Discussion: Atropine 1% drops have previously been associated with new or increased seizure activity in a handful of case reports, however, it is our knowledge that this is the first report associated with 0.01% drops. This is important given the growing use of 0.01% drops as well as higher concentrations such as 0.025 % and 0.05% for the treatment of pediatric myopia. Conclusion: While it cannot be proven that the drops were causative in the seizure events, it is important to consider prior seizures as a relative contraindication to the use of these drops. Atropine has the potential to exacerbate seizure activity, so it is possible that the 0.01% atropine drops played a role in the patient’s seizures. Also, any diagnosis of new-onset seizures in pediatric patients should prompt discontinuation of drops at seizure onset.
Experience with allogeneic hematopoietic stem cell transplantation (HSCT) in mycosis fungoides/Sezary syndrome (MF/SS) is limited to a small number of case reports and case series [1,2]. The advantage of allogeneic HSCT has been indicated in progressive disease in the review of CIBMTR study groups [3]. A consensus is still not available about the intensity and the content of the conditioning regimen due to the rarity of the disease and heterogeneous patient groups.
A case study on Jakob Erdheim-Chester disease.

The overall incidence of meningitis in infants 0-90 days is low; however, it remains a serious cause of morbidity and mortality among affected patients. It is standard of care to perform lumbar punctures as part of the work-up of fever in the first four weeks of life and sick-looking babies up to the age of 90 days. This particular procedure is often refused by parents, and physicians are left to predict the possibility of meningitis based on blood culture results.The aim of this study is to determine whether it would be safe to rule out meningitis based on a negative blood culture in this age group.
Background: Subclavian venous access for pacemaker lead insertion is a common procedure and is normally considered safe in the hands of an expert. However, subclavian venepuncture is not without complications, starting from mild subcutaneous hematoma to pneumothorax. We here present a case of hemoptysis occurring after difficult subclavian vein puncture, which subsequently improved on conservative management only.
Case Summary: A 65-year-old gentleman, post aortic valve replacement had persistent high-grade AV block and was taken up for a dual chamber pacemaker implantation. Immediately following venous access, he had a bout of hemoptysis, which recovered on its own. Post procedure chest x-ray was suggestive of alveolar hemorrhage which cleared gradually in next three-four days.
Discussion: Post subclavian venepuncture hemoptysis is known; but it is a rare complication, arising either because of lung parenchyma injury or arterial injury. This is mostly benign and improves on conservative management only; however rarely it may be massive and life threatening where transcatheter arterial embolization may be required.
The incidence of HBV infections among the pregnant in Europe falls within the range of 1% - 7%, whereas it is 1.7% - 4.3% for HCV.
The aim was to assess the course of pregnancy among women infected with HBV or HCV, and the condition of neonates in the fifth minute after the birth.
The study included 157 pregnant individuals infected with HBV, 53 infected with HCV, and 330 healthy pregnant women. None of the women infected with HBV and HCV as well as from the control group were infected with HIV, and none of them took intoxicants.
Weight of neonates delivered by healthy women was higher as compared with children born by women infected with HBV or HCV (3,517 vs. 3,347 and 3,366). The Apgar score of neonates delivered by women with HBV and HCV infections was lower as compared with the children born by healthy women (9.4 vs. 9.3 vs. 9.7; p < 0.05). Premature births occurred more often in HBV and HCV-infected women than in the control group (14.6% and 24.5% vs. 6.96%; p < 0.05). Miscarriages were significantly more common among the pregnant with HCV infections as compared with the pregnant who were healthy (9.4% vs. 1.8%; p < 0.05). In comparison with the healthy individuals, this group of patients experienced pruritus (10.5% vs. 4.2%; p < 0.05), oedemas (9.4% vs. 2.4%; p < 0.05), and hypertension (9.4% vs. 1.5%; p < 0.05) more often.
An increase in HBV loads was observed between the 6th and 28th – 32nd week of pregnancy among the infected with HBV, and then, a decrease was observed in the 6th months after the delivery.
The pregnant infected with HBV without HBsAg (-) and the infected with HCV are subject to common incidence of premature births. Women infected with HCV often experience oedemas, hypertension, and pruritus.

Inflammation is a natural response of the body to defend itself against potential threats and can be reduced through physical activity, proper nutrition, and the use of herbal medicines, which are medicinal plants. In the study, we aim to examine the anti-inflammatory effects of the volatile and ethanolic fractions of two commonly used medicinal plants, Equisetum arvense, and Baccharis trimera. The essential oils were obtained by hydrodistillation of the fresh leaves of the plants, while the ethanolic extracts were obtained using classical methodologies. All fractions were tested for anti-inflammatory activity, evaluating their ability to stabilize the red blood cell membrane and inhibit the spreading, and phagocytosis by macrophages, at concentrations varying from 200 to 600 µg mL-1. The results of the experiments suggest that the ethanolic fraction of B. trimera shows promising results compared to the positive controls. Our investigations thus contribute to the specialized literature on the use of herbal medicines around nutrition, providing guidance for future studies on these fractions.
A key platform underpinning the traditional understanding of the cardiovascular system, with respect to the behavior of large arterial vessels, is Otto Frank’s Windkessel Hypothesis [1]. This hypothesis posits simply that the smooth muscle walls of large arteries do not undergo rhythmic contractions in synchrony with the heartbeat but, rather, behave as passive elastic tubes undergoing distension from pulsatile pressure waves. The Windkessel Hypothesis is elegant, well described for over a century, ingrained in the understanding of cardiovascular medicine and physiology, and simply wrong.
Several groups have now shown that the arterial smooth muscle wall undergoes rhythmic activation in synchrony with the heartbeat in a variety of tissues, including human brachial artery; canine coronary, femoral, and carotid arteries; rabbit aorta; feline pulmonary artery and rodent aorta [2-8]. The phasing of these events is such that the upstroke of the contraction slightly precedes the upstroke of the pulse wave, suggesting nomenclature for the events as pulse synchronized contractions, or PSCs [3,6-8].
PSCs have been found to be of neurogenic origin, sensitive to the neural blocker tetrodotoxin [3,8]. Although the specific neural pathways regulating PSCs have not been elucidated, the alpha-adrenergic system is at least partially involved, as evidenced by reduction or blockade of PSCs by the alpha-adrenergic blocker phentolamine [8]. Further, PSCs have not been observed following vessel excision in in vitro studies, as an intact nervous system is not present. The pacemaker for the PSC resides in the right atrium, as suggested by two lines of evidence. First, pacing of the right atrial region to faster than spontaneous frequencies leads to a one-to-one correspondence of PSC frequency with the stimulation rate [3]. Additionally, excision of the right, but not the left, atrial appendage results in elimination of PSCs [3]. As the pacemaker region for PSCs and the heartbeat both lie in the right atrium, this may potentially allow for coordination between the heartbeat and pulse wave with PSCs [3,5,8]. Extensive evaluations also have been performed showing the PSC was not an artifact produced either by cardiac contractility or from the vessel distension from the pulse wave [3,5,6].
Symptomatic vasospasm represents an uncommon complication of perimesencephalic nonaneurysmal subarachnoid hemorrhage (SAH) which is a benign form of SAH without any recognizable source of bleeding accounting for about 15% of non-traumatic SAH [1,2].
Idiopathic Pulmonary Fibrosis (IPF) is a chronic and progressive disease without treatment that leads to death. Therefore, to control its progression to pulmonary hypertension is still a challenge. Moreover, there is no study that has investigated the Renin-Angiotensin System in patients with IPF.
Objective: Verify the plasma concentrations of Angiotensin I, Angiotensin II (AngII), Angiotensin-(1-7) [Ang- (1-7)] and Alamandine in patients with IPF.
Methods: Ten IPF patients, with or without PH, were included, and ten controls matched by sex and age. Quantitative plasma peptide concentrations (PPC) were expressed as mean and standard deviation or median and interquartile range. The Student Newman-Keuls t test was used for parametric data, Mann-Whitney for nonparametric data and, to compare proportions, the Fisher exact test was performed. The associations between clinical variables and the PPC were evaluated by Pearson or Spearman correlation coefficients. A p ≤ 0.05 was considered statistically significant.
Results: The Alamandine plasma concentration was significantly (365%) lower in the IPF group and positively associated (r = 0.876) with pulmonary artery pressure (PAP). In addition, only in control group, the forced expiratory volume (FEV1%) was positively associated (p = 0.758) with Ang-(1-7).
Conclusion: This study showed, for the first time, that there is a decrease in Alamandine participation in patients with IPF. The ACE-AngII-AT1 axis may be more active in this disease. In addition, our results suggest that Alamandine might be compensating the increase in PAP, as well as the Ang-(1-7) is improving the forced expiratory volume.
