Laser hair removal complications and the associated risk factors at a tertiary dermatology center: a case-control study.

Laser hair removal (LHR) has been established as a safe and efficient method for eliminating unwanted hair. This study aimed to investigate the frequency of LHR complications and assess the contributing factors. During one year, 16,900 patients undergoing LHR therapy were evaluated for complications. For each case, two external controls were selected (matched based on age, sex, Fitzpatrick skin type (FST) III-IV, and the treated anatomical region). To assess the impact of anatomical region on complication occurrence, each patient was used as their internal control if another area was treated during the same session. GEE analysis was used for statistical analysis.The incidence of LHR complications was calculated to be 0.69%. The most common complications were petechia, purpura, and ecchymosis (31.66%) followed by pigmentation changes (20.0%). LHR complications were most commonly observed in the lower limbs (32.0%), face and neck (23.3%), and genitalia and thighs (22.3%), respectively. Possible risk factors were younger age (OR = 0.74, P-value ≤ 0.001), operating LHR in the head and neck (OR = 5.8, P-value = 0.022), utilization of the alexandrite laser (OR = 2.32, P-value = 0.011), and fluence in the Alexandrite laser (OR = 3.47, P-value = 0.003).Overall, the results of this study indicate that LHR is generally a safe method for removing unwanted hair. However, factors such as younger age, treatment of the facial area, and use of the alexandrite laser especially with higher fluence levels in patients with FST III-IV were identified as potential risk factors.

The miracle of IVUS for unforeseen stent thrombosis: A case report.

Stent thrombosis is a serious complication with high morbidity and mortality rates resulting in cardiac death or nonfatal myocardial infarction that occurs following stent placement during percutaneous coronary intervention (PCI). Stent underexpansion or malapposition are avoidable risk factors for stent thrombosis. Sufficient postdilation should be considered to mitigate this risk, especially with the guidance of intravascular ultrasound (IVUS). We present the case of a 60-year-old man developing a thrombotic lesion inside a stent 2 weeks after PCI for Non-ST-Segment Elevation Myocardial Infarction (NSTEMI), which was strongly related to stent underexpansion and malapposition. This case highlights the importance of IVUS in evaluating procedural success, particularly in assessing stent expansion and apposition.

Devastating fungal endocarditis involving ascending aorta in a patient with a history of aortic valve replacement: a case report.

BACKGROUND: Fungal endocarditis is a rare but serious condition associated with high mortality rates. Various predisposing factors contribute to its occurrence, such as underlying cardiac abnormalities, cardiac surgeries, prosthetic cardiac devices, and central venous catheters. Diagnosing fungal endocarditis, particularly Aspergillus, poses challenges, often complicated by negative blood cultures. CASE PRESENTATION: This report details a case of extensive ascending aorta involvement in Aspergillus endocarditis (AE) in a 24-year-old man with a history of bioprosthesis aortic valve replacement (AVR). Three months post-AVR, he presented with pericardial effusion and aortic rupture, leading to a redo biological valved conduit aortic root replacement (Bentall surgery). Despite the intervention, the tubular graft exhibited extensive Aspergillus involvement, resulting in graft disruption and significant peri-aortic infection. A second redo procedure involving aortic homograft root replacement was performed. Unfortunately, the patient succumbed two days after the surgery. CONCLUSION: A combined approach of medical and surgical therapies is recommended to manage fungal endocarditis. Despite efforts, the mortality rate associated with Aspergillus endocarditis remains unacceptably high, with no significant difference observed between combination therapy and antifungal treatment alone. Further research is essential to explore novel therapeutic strategies and improve outcomes for patients with this challenging condition.

The effect of significant weight loss after bariatric surgery on echocardiographic indices: an observational study focusing on left ventricular deformation by 2D speckle echocardiography and right ventricular size.

BACKGROUND: Obesity is a known risk factor for atherosclerosis and cardiac disease. HYPOTHESIS: This study evaluated the effect of significant weight loss following bariatric surgery on myocardial deformation indices and right ventricular size (RV). This was a prospective cohort study. Morbid obese patients scheduled for bariatric surgery from July 2017 to February 2018 at Firoozgar Hospital were included in our study and referred for transthoracic echocardiography at Rajaie Cardiovascular Medical and Research Center. RESULTS: Thirty-four patients entered the study. The absolute value of global longitudinal strain (GLS) at baseline, 3, and 6 months after surgery was 17.42 ± 2.94%, 18.24 ± 3.09%, and 19.52 ± 2.78%, respectively, with a statistically significant difference from baseline to after six months (P value < 0.001). The absolute value of global circumferential strain (GCS) at baseline, 3, and 6 months after surgery was 20.14 ± 4.22%, 23.32 ± 4.66%, and 24.53 ± 4.52%, respectively, with statistically significant changes (P value < 0.001) from baseline to three months and from baseline to six months and no significant difference from three months to six months. A significant decrease was reported in mechanical dispersion of circumferential strain (38.05 ± 23.81-23.37 ± 20.86 ms, P value = 0.006) 6 months after surgery. Right ventricular size three- and six-month post-surgery showed a significant decrease relative to baseline echocardiography. CONCLUSIONS: Bariatric surgery could enhance cardiac function, as proven by 2D speckle echocardiography. Changes in RV size may be related to weight loss and should be considered when assessing patients who have undergone bariatric surgery.

Extensive right-sided endocarditis in double-chamber right ventricle presented with leukocytoclastic vasculitis.

Congenital heart disease is a risk factor for infective endocarditis (IE). Ventricular septal defects and ventricular outflow tract obstructions are this population's most common causes of endocarditis. We present a patient diagnosed with leukocytoclastic vasculitis, renal, and pulmonary involvement with right-sided IE as an etiology for vasculitis.
