Effect Of Lead On The Skin And Health Of Female Dermatitis Patients Through Cosmetics.

BACKGROUND: Cosmetics have been a part of routine body care not only for the upper classes but also for the middle and lower classes since the dawn of civilization. Cosmetic formulations are in more demand as the public's interest in skin whitening grows. The contamination of cosmetics with heavy metals is a major concern as they containing heavy metals and pose a major risk to human health. This study looks in to the effects of Lead on human skin. METHODS: In this cross sectional study different products were examined. The matrices (scalp hair, blood, serum and nails) of reference and dermatitis cosmetic female patients (seborrhoeic dermatitis, rosacea, allergic contact dermatitis, and irritant contact dermatitis) and cosmetic samples were used in a 2:1 mixture of HNO3 (65%) and H2O2 (30%), and oxidation was performed using a microwave. The oxidized beauty and biological specimen underwent electrothermal atomic emission spectrophotometry after microwave-assisted acid digestion. The validity and precision of the methodology were verified using certified reference materials. Cosmetic products (lipstick, face powder, Eye Liner and Eye shadow) of different brands contain Pb concentrations in the ranges of 50.5-120 µg/g, 14.6-30.7 µg/g, 2.87-4.25 µg/g and 15.3-21.6 µg/g, respectively. RESULTS: In the present study, cosmetic products (lipstick (N=15), face powder (N=13), eye liner (N=11), eye shadow (N=15) and female patients with dermatitis (N=252) residing in Hyderabad city, Sindh, Pakistan, was investigated. The outcome of this investigation showed significantly higher levels of Pb in biological samples (blood and scalp hair) of different types of female dermatitis patients than in reference subjects (p<0.001). CONCLUSIONS: The cosmetic products, especially with regard to heavy metals adulteration, are in use by the female population.

Two Consecutive Cases of Quadricuspid Aortic Valve and a Review of 149 Cases.

The quadricuspid aortic valve (QAV) is a rare congenital anomaly that typically is unrelated to other cardiac anomalies. It usually is discovered incidentally through imaging modalities such as echocardiogram or computed tomography angiogram, during surgery, or autopsy. Some patients with QAV develop aortic regurgitation and, rarely, other cardiovascular complications like aortic aneurysm. Due to its rarity, it is difficult to characterize these patients or standardize management. However, review of case reports can be very useful in rare medical conditions such as QAV. In this manuscript, in addition to presenting two cases of QAV, the authors reviewed 149 cases of QAV from 2010 to 2020 from published case studies and series in order to gain a better insight into the characteristics of the patient population with QAV and its management.

Pulmonary Artery Aneurysm Associated With Severe Pulmonary Hypertension in a Patient Presenting for Double Lung Transplant: Review of a Rare Disorder and Role of Transesophageal Echocardiography.

Pulmonary artery aneurysm (PAA) is a rare disorder that may be classified as congenital, acquired, or idiopathic, in the case of unclear etiology. When associated with severe idiopathic pulmonary arterial hypertension, such a case of PAA may present to the operating room as an indication for lung transplantation. In this article, we present such a case of a patient with a giant main and right PAA that underwent a double lung transplant. We describe the pathophysiology and natural course of this PAA and discuss the role of intraoperative transesophageal echocardiography in the management of patients with this rare diagnosis.

Impending Paradoxical Embolism: Perioperative Management and Role of Transesophageal Echocardiography.

Impending paradoxical embolism is a rare but potentially life-threatening complication of venous thromboembolism that is usually associated with acute pulmonary embolism and a right to left atrial shunt. Patients may have associated right ventricular pressure or volume overload with subsequent failure. Transesophageal echocardiography is the preferred diagnostic test of choice in this patient group. Definitive management has yet to be clearly defined. However, emergent surgical removal of the entrapped intracardiac blood thrombus may be necessary. In this article, we review a case of impending paradoxical embolism managed surgically and describe the perioperative anesthetic considerations in this patient population, along with the role of intraoperative transesophageal echocardiography.

Persistent Left Superior Vena Cava in a Heart Transplant Recipient's Native Heart: A Rare Case Diagnosed by Transesophageal Echocardiogram.

Persistent left superior vena cava (PLSVC) is a rare abnormality with incidence reported as 0.3% to 0.5% in the general population and about 10 times higher in patients with congenital heart disease. The diagnosis of PLSVC in native or donor hearts of patients undergoing heart transplants has been reported in surgical journals. However, this rare finding has not been described in similar heart transplant settings in anesthesia literature. This case describes a 44-year-old male orthotopic heart transplant recipient who was incidentally diagnosed with PLSVC in his native heart on transesophageal echocardiogram after a central venous catheter placement. The particular position of the central venous catheter, in our case, raised the suspicion of PLSVC but needed further verification. With the help of images and videos, we demonstrate that transesophageal echocardiogram can be instrumental in diagnosing PLSVC. Furthermore, the case highlights the importance of effectively communicating with the surgeon about such a finding so that the surgical plan can be modified in a timely manner.

Survival in patients with poorly compressible leg arteries.

OBJECTIVES: This study sought to compare survival of patients with poorly compressible arteries (PCA) to those with a normal ankle-brachial index (ABI) and those with peripheral arterial disease (PAD). BACKGROUND: Limited data are available regarding survival in patients with PCA identified in the clinical setting by noninvasive lower extremity arterial evaluation. METHODS: We conducted a historical cohort study of consecutive patients who underwent outpatient, noninvasive lower extremity arterial evaluation at the Mayo Clinic, Rochester, Minnesota, from January 1998 through December 2007, and who were followed for a mean duration of 5.8 ± 3.1 years. An ABI 1.00 to 1.30 was considered normal, PAD was defined as a resting or post-exercise ABI ≤0.90, and PCA defined as an ABI ≥1.4 and/or an ankle systolic blood pressure >255 mm Hg. Patients were followed for all-cause mortality through September 30, 2009. RESULTS: Of 16,493 individuals (mean age 67.8 ± 13.0 years, 59% male); 29% had normal ABI, 54% had PAD, and 17% had PCA. During follow-up (mean duration 5.8 ± 3.1 years), 4,365 patients (26%) died. The percent alive at the end of the study period was 88%, 70%, and 60% for normal ABI, PAD, and PCA, respectively. After adjustment for age, sex, cardiovascular risk factors, comorbid conditions, and medication use, the hazard ratios (95% confidence intervals) of death associated with PCA were 2.0 (1.8 to 2.2) and 1.3 (1.2 to 1.4) compared with the normal ABI and PAD groups, respectively. CONCLUSIONS: Patients identified by noninvasive vascular testing to have poorly compressible leg arteries have poor survival, worse than those with a normal ABI or those with PAD.

Electromagnetic interference in a cardiac pacemaker during cauterization with the coagulating, not cutting mode.

Electromagnetic interference in pacemakers has almost always been reported in association with the cutting mode of monopolar electrocautery and rarely in association with the coagulation mode. We report a case of electrocautery-induced electromagnetic interference with a DDDR pacemaker (dual-chamber paced, dual-chamber sensed, dual response to sensing, and rate modulated) in the coagulating and not cutting mode during a spine procedure. We also discuss the factors affecting intraoperative electromagnetic interference. A 74-year-old man experienced intraoperative electromagnetic interference that resulted in asystole caused by surgical electrocautery in the coagulation mode while the electrodispersive pad was placed at different locations and distances from the operating site (This electromagnetic interference did not occur during the use of the cutting mode). However, because of careful management, the outcome was favorable. Clinicians should be aware that the coagulation mode of electrocautery can cause electromagnetic interference and hemodynamic instability. Heightened vigilance and preparedness can ensure a favorable outcome.

Sex/gender medicine. The biological basis for personalized care in cardiovascular medicine.

Sex differences in morbidity and mortality associated with cardiovascular disease have been recognized by the medical community for decades. Investigation into the underlying biological basis of these differences was largely neglected by the scientific community until a report released by the Institute of Medicine in the United States in 2001 "Exploring the Biological Contributions to Human Health: Does Sex Matter?" Recommendations from this report included the need for more accurate use of the terms "sex" and "gender", better tools and resources to study the biological basis of sex differences, integration of findings from different levels of biological organization and continued synergy between basic and clinical researchers. Ten years after the Institute's report, this review evaluates some of the sex differences in cardiovascular disease, reviews new approaches to study sex differences and emphasizes areas where further research is required. In the era of personalized medicine, the study of the biological basis of sex differences promises to optimize preventive, diagnostic and therapeutic strategies for cardiovascular disease in men and women, but will require diligence by the scientific and medical communities to remember that sex does matter.

White blood cell count predicts all-cause mortality in patients with suspected peripheral arterial disease.

OBJECTIVE: We investigated whether markers of inflammation-white blood cell (WBC) count, C-reactive protein (CRP), and lipoprotein-associated phospholipase A2-are associated with mortality in patients referred for noninvasive lower-extremity arterial evaluation. METHODS: Participants (n = 242, mean age 68 years, 54% men) were followed for a median of 71 months. Ankle-brachial index (ABI), WBC count, plasma CRP, and lipoprotein-associated phospholipase A2 were measured at the start of the study. Factors associated with all-cause mortality were identified using Cox proportional hazards. RESULTS: During the follow-up period, 56 patients (25%) died. Factors associated with higher mortality were greater age, history of coronary artery disease/cerebrovascular disease, lower ABI, higher serum creatinine, and higher WBC count/plasma CRP. In stepwise multivariable regression analysis, ABI, serum creatinine, WBC count, and CRP were associated significantly with mortality. Patients in the top tertile of WBC count and CRP level had a relative risk of mortality of 3.37 (confidence interval [CI], 1.56-7.27) and 2.12 (CI, 0.97-4.62), respectively. However, only the WBC count contributed incrementally to prediction of mortality. Inferences were similar when analyses were limited to patients with peripheral arterial disease (ABI<0.9, n = 114). CONCLUSION: WBC count, but not plasma CRP level, provides incremental information about the risk of death in patients referred for lower-extremity arterial evaluation and in the subset of these patients with peripheral arterial disease.

An unusual presentation of enterocolic lymphocytic phlebitis.

Enterocolic lymphocytic phlebitis (ELP) is a recently described disease characterized by phlebitis in the wall and mesentery of the colon and small bowel. Unlike other systemic or localized vasculitic diseases that can have similar gastrointestinal manifestations, there is no involvement of the arterial system or evidence of systemic vasculitis. The lymphocytic phlebitis affects not only the grossly involved intestinal segment but also the apparently healthy bowel. The diagnosis of ELP is histologic, and other systemic vasculitis must be ruled out. Surgical resection of the bowel not only provides the diagnostic tissue but also leads to resolution of the symptoms. In the literature, ELP has most commonly been reported to present as an acute abdomen. We describe a case of ELP presenting as a large abdominal mass, without evidence of an acute abdomen. This mass was actually diffusely thickened colonic serosa, caused by extensive organizing fat necrosis and marked edema of the serosa and bowel wall.
