The Patency Rate of Endovascular Procedure in Patients with Superior Vena Cava Syndrome Caused by Intravenous Catheterization: A Case Series and Longitudinal Study

Introduction: Different methods have been well addressed in literature in terms of treating superior vena cava (SVC) syndrome; nevertheless, the patency of endovascular treatment has rarely been investigated in patients with SVC syndrome in patients with central venous access. Objectives: The present study was performed to assess the patency rate of endovascular procedure in patients with SVC syndrome caused by intravenous catheterization. Methods: The present case series and longitudinal study was conducted on patients with SVC syndrome in presence of central venous catheter who underwent venoplasty. Computed tomography (CT) venography was performed 1, 6 and 12 months after venoplasty. Facial swelling, facial discomfort, extremity edema, arteriovenous fistula (AVF) dysfunction, impairment in dialysis and SVC stenosis were measured at baseline and 1, 6 and 12 months after venoplasty. Results: Out of 20 investigated patients, 11 (55%) were male. Significantly decreases were observed in the median grades of facial swelling and extremity edema in the follow-up (P<0.001). The decrease in facial discomfort was statistically insignificant (P=0.129), and the median grade of SVC stenosis significantly decreased from 1.5 to zero in the follow-up (P<0.001). A statistically-significant decrease was observed in AVF dysfunction (P=0.007), and impairment in dialysis significantly decreased after the intervention during the follow-up (P<0.001). Conclusion: Findings of the present study revealed the appropriate patency rate of endovascular treatment in patients with SVC syndrome in presence of central venous catheter

The Role of Insulin-Like Growth Factor-1 and Pregnancy-Associated Plasma Protein-A in Diagnosis of Acute Coronary Syndrome and Its Related Morbidities

Introduction: Pregnancy-associated plasma protein-A (PAPP-A) is a metalloproteinase that plays a role in atherosclerotic plaque destabilization. In recent studies, insulin-like growth factor-1 (IGF-1) has been introduced as a mediator of atherosclerosis. PAPP-A and IGF-1 level may be important diagnostic indicators of acute coronary syndrome (ACS). Objective: The present study tried to assess the diagnostic role of IGF-1 and PAPP-A biomarkers in ACS spectrum. Methods: The serum level of IGF-1, PAPP-A and troponin I was determined in 121 consecutive patients with ACS. Relationships were assessed by t-test, ANOVA and the non-parametric equivalent. Accuracy of biomarkers was measured by the area under the ROC curve (AUC) and optimal cut-off points to diagnose STEMI and NSTEMI using Youden index. Results: In patients with acute ST segment elevation myocardial infarction (STEMI), all of these three biomarkers were significantly higher than those in patients with unstable angina (P= 0.028 for IGF-1, P<0.001 for PAPP-A and Troponin-I). Mean level of IGF-1 in patients with renal failure was significantly higher than that in patients without renal failure (137.9±35.1 vs 105.1±46.9, P=0.003), but PAPP-A and serum Troponin-I level had no significant difference in renal failure groups (P>0.05).  ROC curve analysis showed that after Troponin-I, PAPP-A was a good discriminator between patients with STEMI and patients with unstable angina (AUC=0.79). Optimum cut-off value for PAPP-A was found to be 89.2 ng/ml, with sensitivity and specificity of 66.7% and 83.8%, respectively. Conclusion: PAPP-A can be a novel biomarker for both identification of patients with STEMI and risk stratification in patients with ACS

A case of moyamoya syndrome and spherocytosis with concurrent interstitial lung disease who underwent laparoscopic splenectomy is being reported. A theory regarding their coexistence is being forwarded together with their anesthetic management. According to our search, this is the fourth case of moyamoya syndrome and the first case with an associated interstitial lung disease in a 10-year-old child

The Effect of Preoperative Creatinine Clearances on Postoperative Oxygenation in Coronary Artery Bypass Grafting: A Cohort Study

 End-stage kidney disease has a high prevalence in patients undergone Coronary Artery Bypass Grafting (CABG) and could cause a wide spectrum of morbidities, due to deep water and electrolyte or acid-base impairments. The aim of this study was to assess the effect of low Creatinine Clearances (ClCr) on arterial oxygenation defect, as common post-CABG morbidity. The study was conducted as a prospective cohort, the pure on pump CABG patients were grouped based on their preoperative ClCr to groups A (ClCr≥60) and B (ClCr<60). Postoperatively, the PaO2/FiO2 values in 1 hour after ICU admission and 4 hours after extubation, intubation time duration, duration of ICU stay and high concentration oxygen demand were compared. Among 229 patients who remain in the study, 121 were in group A, and 108 in B group. Except for age, weight, height, BMI, and pump time, other demographic and independent variables were similar between two groups. The higher values of PaO2/FiO2 and PaO2, 1 hour after ICU admission and 4 hours after extubation in group B, were not statistically significant, while SpO2 value, 1 hour after ICU admission was higher in group B (98.19±1.37) in compare with group A (97.78±1.57) (P=0.040). Intubation time duration (10.85 in A vs. 12.79 in B; P=0.306), duration of ICU stay (39.04 in A vs. 43.09 in B; P=0.114) and high concentration oxygen demand (2.5% in A vs. 3.8% in B; P=0.089) were similar between groups of study. Lower Preoperative ClCr values do not deteriorate post-CABG arterial oxygenation

Prevalence of Attention Deficit Hyperactivity Disorder in Pediatrics Patients Newly Diagnosed with Gastroesophageal Reflux Disease

Background: Gastroesophageal reflux disease (GERD) is associated with a number of comorbidities in pediatrics. However, its association with attention deficit hyperactivity disorder (ADHD) has not been reported. The aim of the present study was to investigate the prevalence of ADHD in pediatric patients newly diagnosed with GERD. Materials and Methods: Sixty newly-diagnosed treatment naive GERD patients and sixty healthy controls aging between 5 to 12 years referring to the Children and Adolescent’s medical center, Tehran, Iran were recruited in a case-control study during the year 2015. Then patients were evaluated for ADHD by a psychiatrist according to the DSM-IV criteria. The revised Conners' Parent Rating Scale (CPRS-R) was used for assessment of the symptoms of ADHD. To screen for psychiatry disorders other than ADHD, the Kiddie-Sads-Present and Lifetime Version (K-SADS-PL) questionnaire was used. Logistic regression analysis was used for modeling the association between GERD and ADHD in the study sample. Results: The mean age of GERD patients was 5.77±2.27 and for non-GERD controls was 6.03±2.52 (P= 0.543). Thirty-three out of 60 (55%) GERD patients and 37 out of 60(61.66%) non-GERD controls were male (P: 0.579). Prevalence of ADHD was 33.60 (55%) in GERD patients and 10.60 (16.66%) in non-GERD (

Impact of Sitting or Semi-Setting Position of Patients During Breast Surgery on Hemodynamic Indexes

Background: Keeping the patient in a sitting or semi-sitting position for time-consuming oncoplastic breast surgery is a major challenge for anesthesiologists due to several considerations. This cohort study was conducted on two groups of patients undergoing breast surgery. Methods: Study participants were categorized into two groups: one group was composed of normotensive women (group A) and the other group comprised women with controlled hypertension (group B). After the induction of anesthesia in the supine position, the position was changed to sitting and the surgery was done in the sitting position. Hemodynamic monitoring included ECG, heart rate, non-invasive blood pressure (NIBP), invasive blood pressure (IBP), cardiac output (CO), arterial O2 saturation (SPO2), end-tidal CO2 (EtCO2), and bispectral index (BIS). The amount of administrated fluid and vasopressor was recorded for each patient. Any episode of hemodynamic instability was recorded, too. Results: Hemodynamic variation occurred in both groups, but the changes were more significant in group B and the amount of fluid and vasopressor administration was more prominent in group B. Changing the position caused no significant variation in BIS, SPO2, and EtCO2 in the two groups. Conclusions: The sitting position can be safe for time-consuming oncoplastic breast surgery using adequate hemodynamic monitoring. Hemodynamic changes are more significant in patients with controlled hypertension, and more medical interference is needed for these patients

Comparison of Postoperative Pain between Infiltrative Local Anesthesia plus Paracetamol and Total Intravenous Anesthesia plus Paracetamol in Ambulatory Breast Surgery

Background: Acute postoperative pain is an important surgical side effect that may delay patient discharge in ambulatory operations; moreover, the strategies used to alleviate pain may cause side effects that require longer hospitalization to recover. In this clinical trial, we compared two current anesthetic methods with special concerns about postoperative pain intensity beside other important components of ambulatory anesthesia. Methods: This clinical trial was conducted on two age-matched groups of 75 members who underwent ambulatory breast surgery. Patients in the first group (GA) underwent general anesthesia with propofol plus remifentanil by employing a laryngeal mask airway. In the second group (LA), the surgeon used infiltration of 2% lidocaine in the breast tissue and midazolam was applied as premedication. At the end of surgery, paracetamol was administered to all patients in both groups. The pain score was evaluated when the patients were fully awake using a numerical pain rating scale. Patients with severe pain received analgesia. The length of postanesthesia care unit (PACU) stay was recorded for each patient. Results: None of the patients in the LA group were satisfied because of the experience of needle insertion into their breast tissue (P = 0.001). The patients in the LA group experienced more pain in PACU requiring adjuvant analgesia (P = 0.001). Patients in the LA group had longer PACU admission (P = 0.001). Conclusions: Patients in the LA group had higher pain scores and were dissatisfied with the plan of their anesthesia. This may confirm the role of preemptive analgesia or the effect of emotional stress of breast tissue needling in wakeful patient

Sensorineural hearing loss in patients with chronic suppurative otitis media: Is there a significant correlation?

Introduction: Hearing loss as a sequel of chronic suppurative otitis media (CSOM) is often conductive, but recent studies have found an additional sensorineural component in these patients, thus demonstrating inner ear damage. The aim of the study was to determine the association between CSOM and sensorineural hearing loss (SNHL) and to assess the influence of patient’s age, duration of disease, and presence of cholesteatoma and ossicular erosion on the degree of SNHL. Methods: In a retrospective study, the medical records of 119 patients who underwent surgery was reviewed. Seventy patients met the inclusion criteria of unilateral otorrhea, normal contralateral ear on otoscopy, and age between 10–65 years with no history of head trauma or ear surgery or familial hearing loss. Bone conduction (BC) thresholds for affected and contralateral ear were measured at frequencies of 500, 1000, 2000, and 4000 Hz. Data analysis was performed using SPSS 13 with independent-samples t-test, Pearson correlation test, and twotailed analysis. A p ≤ 0.05 was considered statistically significant. Results: Significant higher BC thresholds were found in the affected ear than in the normal ear for each frequency (p < 0.001), which increased with increasing frequency (7.00 dB at the 500 Hz and 9.71 dB at the 4000 Hz). There was a significant correlation between age and degree of SNHL (r = 0.422, p < 0.001) but no significant correlation was in duration of the disease (r = 0.119, p > 0.05). There was no relationship between presence of cholesteatoma and ossicular erosion with SNHL (p > 0.05). Conclusion: These findings demonstrate that CSOM is associated with some degree of SNHL and cochlear damage, and higher frequencies are more affected. Aging can act as a precipitating factor in this pathological process

A survey of physicians’ opinions about the treatment of subsegmental pulmonary embolism

Introduction The aim of this study was to survey the attitudes of internists, cardiologists, and pulmonologists regarding treatment or no treatment of isolated subsegmental pulmonary embolism (ISSPE) with anticoagulant drugs. Methods Qualified physicians were asked to select their management options from a questionnaire that included a patient scenario with subsegmental pulmonary embolism (SSPE) and negative past medical history of thromboembolism. Results A total of 113 physicians responded to the survey. Of these, 8.8% preferred not to treat patients without further evaluation; 15% decided not to treat, but follow-up the patient with a serial lower-limb colour Doppler ultrasonography; 1.7% preferred anticoagulant treatment only during hospitalization and follow-up without medication; 5% preferred anticoagulant treatment for less than 3 months; and 34.5% chose a 3--6-month treatment with anticoagulation. Furthermore, 24% of physicians opted for anticoagulant treatment for more than 6 months, and 9.7% left the decision up to the patient. Opting not to treat was an option selected by more board-certified faculty members specialized in cardiology, internal medicine, and pulmonology compared with residents (p = 0.038). Willingness to provide anticoagulant therapy in the internal medicine, cardiology and pulmonology groups was 56.6%, 37.3% and 6%, respectively (p = 0.007). Conclusion The majority of physicians surveyed prefer anticoagulant therapy in patients with SSPE
