A Comparative Analysis of Intermittent and Continuous Phototherapy in Patients with Neonatal Jaundice

Aim: To compare the outcome of intermittent phototherapy versus continuous phototherapy in treatment of neonatal jaundice. Study Design: Randomized clinical trial (RCT). Place and Duration: This study was conducted at Department of pediatrics, neonatal ward, Liaquat university hospital Hyderabad/Jamshoro, from 8 January to 7 July 2020 Methodology: There were 222 neonate with jaundice, which were randomly allocated into two groups. One hundred and one neonates were in group “A” who received continuous phototherapy while 111 neonates were treated with intermittent phototherapy called group B. Phototherapy units were identical regarding their manufacture and radiance with 5 blue light tubes at a distance of 15-20 cm above neonate that produced the irradiance of 20µW/cm2/nm at 420-470 nm. Serum bilirubin levels were measured every 12 hourly after starting phototherapy up to 48 hours. SPSS version 22 was used for data analysis. Results: The average age of the neonates was 2.23±1.45 days. In this study, the reduction of bilirubin level in both groups after 12, 24, 36, 48 hours of phototherapy and at the time of discharge was not different between groups. Conclusion: Intermittent and continuous phototherapies were found to be equally effective. Because of its additional benefits, intermittent phototherapy can be adopted as a routine procedure instead of continuous phototherapy in neonatal care units, however, it needs to be confirmed by large scale RCTs.

Abstract Background We aimed to determine the efficacy and safety of multiple doses of intravenous tranexamic acid (IV-TXA) on perioperative blood loss in patients with rheumatoid arthritis (RA) who had undergone primary unilateral total knee arthroplasty (TKA). Methods For this single-center, single-blind randomized controlled clinical trial, 10 male and 87 female participants with RA, aged 50–75 years, who underwent unilateral primary TKA were recruited. The patients received one dose of 1 g IV-TXA 10 min before skin incision, followed by articular injection of 1.5 g tranexamic acid after cavity suture during the surgery. The patients were randomly assigned (1:1) into two groups and received an additional single dose of IV-TXA (1 g) for 3 h (group A) or three doses of IV-TXA (1 g) for 3, 6, and 12 h (group B) postoperatively. Primary outcomes were total blood loss (TBL), hidden blood loss (HBL), and maximum hemoglobin (Hb) level decrease. Secondary outcomes were transfusion rate and D-dimer levels. All parameters were measured postoperatively during inpatient hospital stay. Results The mean TBL, HBL, and maximum Hb level decrease in group B (506.1 ± 227.0 mL, 471.6 ± 224.0 mL, and 17.5 ± 7.7 g/L, respectively) were significantly lower than those in group A (608.8 ± 244.8 mL, P = 0.035; 574.0 ± 242.3 mL, P = 0.033; and 23.42 ± 9.2 g/L, P = 0.001, respectively). No episode of transfusion occurred. The D-dimer level was lower in group B than in group A on postoperative day 1 (P < 0.001), and the incidence of thromboembolic events was similar between the groups (P > 0.05). Conclusion In patients with RA, three doses of postoperative IV-TXA further facilitated HBL and Hb level decrease without increasing the incidence of adverse events in a short period after TKA. Trial registration The trial was registered in the Chinese Clinical Trial Registry (ChiCTR1900025013).

Methodology: This Prospective Interventional trial was conducted at Department of General Surgery, Liaquat University Hospital Hyderabad from February 2018 to January 2019. Females with breast carcinoma admitted for modified radical mastectomy were included. Patients were divided into two groups. Groups I underwent one drain placement and group II underwent two drains placement. All patients were observed to measure and record the volume of the fluid. Patients were discharged from Hospital in stable condition and after removal of drains, and followed up weekly for one month. Data was recorded on self-made proforma and analyzed by using SPSS-20. Results: Total of 80 patients were selected, 38 in group A and 42 in group B. Mean age of patients of group A was 49.08 ± 9.89 years and group B was 51.40 ± 13.59 years. , Excised Mass weight was lesser in group A as compared to group B. Mean volume of drain discharge was significantly higher in Group B 323.43 ± 158.88 ml, while it was in group A 230.29± 200.98, findings were statistically significant 0.013. Seroma formation was statistically insignificant among both groups as 8(21.1%) in group A and 10(23.8%) in group B, p-value 0.768. Conclusion: One-drain and two-drain insertion are equally effective to reduce the seroma formation after modified radical mastectomy; however, one drain insertion leads to more patient compliance and comfort with probably less morbidity and cost.

Abstract Background Colorectal cancer (CRC) is one of the leading causes of mortality and morbidity in the world. It is the third most common malignancy after lung & breast and the fourth leading cause of cancer-related deaths worldwide, accounting for approximately 1,400,000 new cases and about 700,000 deaths worldwide. Objectives The aim of this retrospective study is to compare the epidemiology, clinicopathologic features, different treatment modalities and outcomes regarding disease free survival (DFS), progression free survival (PFS) & overall survival (OS) of colorectal cancer disease between cases presented to Ain shams university hospital & to Luxor international hospital in 3 consecutive years. Patients and Methods The study is retrospective comparative study. Clinical oncology department in Ain Shams University Hospital and Luxor International Hospital. The data Collected from January 2013 to December 2015. This study analyzed hospital records of patients who diagnosed with colorectal cancer (CRC) and allocated into two groups: Group A: CRC patients presented to Ain-Shams University Hospital from January 2013 to December 2015, group B: CRC patients presented to Luxor International Hospital from January 2013 to December 2015. Results There was no statistically significant difference regarding age parameter in LIH when compared to ASU, but the study was consistent with higher incidence in patients who were aged more than forty- accounted about 70.5% in all CRC cases. Cases less than 40 years old, in group A were 35.2%, while in Group B were 23.5%. Even there was no statistically significant difference but it may be attributable to more westernization in Lower Egypt. Other explanation may be due to decreased low socioeconomic status and different lifestyle factors in more developing region what increase risk of colorectal cancer. Among our cases, there is no statistically significant difference regarding gender between the two hospitals. Both sexes almost were affected equally, females appeared to be at a slightly higher risk of developing CRC cancer with current prevalence 1.3:1 in ASU group, and 1.1:1 in LIH group. Conclusion The need to increase awareness about CRC in Egypt especially upper Egypt, is recommended. An awareness campaign should be performed to promote detection of CRC at its earliest and most curable stage by recognizing early symptoms and enabling early referrals for colonoscopy. Those at higher risk should be offered more intensive surveillance. Similarity of the data from different centers suggests that this is the picture of colorectal cancer typical of Egypt.

COVID-19 respiratory failure is a life-threatening condition. Oxygenation targets were evaluated in a non-ICU setting. In this retrospective, observational study, we enrolled all patients admitted to the University Hospital of Genoa, Italy, between 1 February and 31 May 2020 with an RT-PCR positive for SARS-CoV-2. PaO2, PaO2/FiO2 and SatO2% were collected and analyzed at time 0 and in case of admission, patients who required or not C-PAP (groups A and B) were categorized. Each measurement was correlated to adverse outcome. A total of 483 patients were enrolled, and 369 were admitted to hospital. Of these, 153 required C-PAP and 266 had an adverse outcome. Patients with PaO2 <60 and >100 had a higher rate of adverse outcome at time 0, in groups A and B (OR 2.52, 3.45, 2.01, respectively). About the PaO2/FiO2 ratio, the OR for < 300 was 3.10 at time 0, 4.01 in group A and 4.79 in group B. Similar odds were found for < 200 in any groups and < 100 except for group B (OR 11.57). SatO2 < 94% showed OR 1.34, 3.52 and 19.12 at time 0, in groups A and B, respectively. PaO2 < 60 and >100, SatO2 < 94% and PaO2/FiO2 ratio < 300 showed at least two- to three-fold correlation to adverse outcome. This may provide simple but clear targets for clinicians facing COVID-19 respiratory failure in a non ICU-setting.

BACKGROUND With the growing stress on hospitals caused by the COVID-19 pandemic, the need for home-based solutions has become a necessity to support these overwhelmed hospitals. OBJECTIVE The goal of this study was to compare two nonpharmacological respiratory treatment methods for home-isolated COVID-19 patients using a newly developed telemanagement health care system. METHODS In this single-blinded randomized clinical trial, 60 patients with stage 1 pneumonia caused by SARS-CoV-2 infection were treated. Group A (n=30) received oxygen therapy with bilevel positive airway pressure (BiPAP) ventilation, and Group B (n=30) received osteopathic manipulative respiratory and physical therapy techniques. Arterial blood gases of PaO2 and PaCO2, pH, vital signs (ie, temperature, respiratory rate, oxygen saturation, heart rate, and blood pressure), and chest computed tomography scans were used for follow-up and for assessment of the course and duration of recovery. RESULTS Analysis of the results showed a significant difference between the two groups (P<.05), with Group A showing shorter recovery periods than Group B (mean 14.9, SD 1.7 days, and mean 23.9, SD 2.3 days, respectively). Significant differences were also observed between baseline and final readings in all of the outcome measures in both groups (P<.05). Regarding posttreatment satisfaction with our proposed telemanagement health care system, positive responses were given by most of the patients in both groups. CONCLUSIONS It was found that home-based oxygen therapy with BiPAP can be a more effective prophylactic treatment approach than osteopathic manipulative respiratory and physical therapy techniques, as it can impede exacerbation of early-stage COVID-19 pneumonia. Telemanagement health care systems are promising methods to help in the pandemic-related shortage of hospital beds, as they showed reasonable effectiveness and reliability in the monitoring and management of patients with early-stage COVID-19 pneumonia.

Olecranon Fractures

Background: Fractures of olecranon are common fractures in upper limb. Tension band wiring (TBW) and plate fixation (PF) are mostly used techniques but choice is based on type of fracture and surgeon’s preference.Methods: A study assessed functional results in 28 patients that were enrolled after the clinical event of trauma has occurred. Patients were divided into two groups- Group (A) for TBW and Group (B) for PF; here gender, age and side of fracture were ignored. Post-operative functional outcome were evaluated by using the Mayo Elbow Performance (MEP) and the Disabilities of the Arm, Shoulder and Hand (DASH) score parameters.Results: Mean (SD) union time as determined by postoperative radiographs was 8.5 (1.48) weeks for group (A) and 9 (2.08) weeks for group (B). Mean (SD) MEP score at 9 months in group (A) 84.28 (7.28) and 80.71 (10.92) in group (B). Mean (SD) DASH at 9 months in group (A) 12.2 (8.8) and 11.7 (10.4) in group (B). Complications were reported in group (A) 6 patient (42.85%) out of 14 patients and in group (B) 1 patient (7.14%) out of 14 patients.Conclusions: The current study shows that there are no significant differences in functional outcome between both the study groups. Due to lesser complications, we recommend the plate fixation approach as the better choice for transverse displaced olecranon fractures. More large scale studies are required to further confirm our results.

The Impact

Introduction: Thyroid and parathyroid diseases are very common. Most of these cases are in women and may be amenable to surgery. The patient’s perception that these are not life-threatening diseases leads them to expect an excellent aesthetic result, since the surgical incision area is clearly visible. Objective: To evaluate different scarring outcomes using three different energy-based devices (Harmonic Focus®, Johnson & Johnson, New Brunswick, NJ; Thunderbeat Open Fine Jaw®, Olympus Medical, Tokyo, Japan; LigaSure Small Jaw®, Medtronic, Dublin, Ireland) and to determine the impact of post-thyroidectomy/parathyroidectomy scars on the patient’s quality of life. Methods: One hundred female patients who underwent thyroidectomy or parathyroidectomy between September 2017 and September 2019 at the Endocrine and Minimally Invasive Surgery Department of Messina University Hospital were recruited. A retrospective analysis assessed the thickness of the cervical scar via ultrasound imaging, and the patient’s degree of satisfaction through the Patient and Observer Scar Assessment Scale (POSAS) and the Body Dysmorphic Disorder Questionnaire (BDDQ). Results: The patients were divided into three groups according to the energy-device used: group A (LigaSure SJ (n=38), group B (Harmonic F, n=32) and group C (Thunderbeat OFJ, n=30). The three groups were homogeneous with respect to number of patients, age and surgical procedures. The best aesthetic result, which correlated with the lowest scar thickness, was observed in group A; these patients were more satisfied than those in the other two groups. Moreover, correlations between scar thickness and quantitative variables (such as age or BMI) were not found in any of the groups. Conclusions: Based on the data collected and our experience, the LigaSure Small Jaw® (Medtronic) seems to offer the best aesthetic outcome in patients who undergo transverse cervicotomy for thyroid and parathyroid diseases. However, further prospective studies involving a greater number of cases are needed.

Af Recurrence

Background: Heart failure (HF) is the leading cause of death in patients with atrial fibrillation (AF). Radiofrequency catheter ablation (RFCA) of AF is effective for maintaining sinus rhythm though its impact on heart failure still remains controversial. Purpose: We sought to elucidate whether AF recurrence following RFCA was associated with subsequent HF hospitalizations. Methods: We conducted a large-scale, prospective, multicenter, observational study. A total of 4931 consecutive patients who underwent an initial RFCA for AF with longer than 1-year of follow-up in 26 centers were enrolled (average age, 64±10 years; non-paroxysmal AF, 35.7%). The median follow-up duration was 2.9 years. The primary endpoint was an HF hospitalization more than 1-year after the index RFCA. We compared the patients without AF recurrences (group A) to those with AF recurrences within 1-year post RFCA (group B). Results: The 1-year cumulative incidence of AF recurrences after a single procedure was 30.7% (group A=3418, group B=1513 patients). Group B had a lower body mass index (group A vs. group B,24.1±3.6 vs. 23.8±3.4 kg/m 2 , p=0.014), longer history of AF (1.9 vs. 3.1 years, p<0.0001), higher prevalence of non-paroxysmal AF (32.1% vs. 33.9%, p<0.0001), and valvular heart disease (5.9% vs. 7.8%, p=0.013). They also had a lower ejection fraction (63.7±9.4% vs. 62.8±9.6%, p=0.0043) and larger left atrial dimeter (39.7±6.6 vs. 40.6±7.0 mm, p<0.0001) on echocardiography. Hospitalizations for HF were observed in 57 patients (1.14%) more than 1-year after the RFCA and were significantly higher in group B than group A (group A vs. group B, 0.91% vs 1.72%, log-rank p=0.019). Conclusions: Among AF patients receiving RFCA, those with AF recurrences were at a greater risk of subsequent heart failure hospitalizations than those without AF recurrences. Recognition that AF recurrence following RFCA is a risk factor for a subsequent HF-related hospitalization is appropriate in clinical practice.

Objective: There have been few reports addressing asymmetric bilateral cleft lip repair with contralateral lesser form defects. Two studies have described the thin medial tubercle as the most common remaining labial deformity. In this study, we aimed to evaluate the use of a foxtail-shaped vermilion flap to reconstruct the median tubercle in primary repair. Design: A blinded retrospective study of photography and chart review. Setting: Shinshu University Hospital, tertiary care. Private practice. Patients: Forty-nine patients with asymmetric bilateral cleft lip with lesser form defects treated using a primary “unilateral” repair by the senior author (S.Y.) between 2007 and 2017. Interventions: The foxtail-shaped vermilion flap was applied at the time of the primary nasolabial repair. This flap is similar to Noordhoff laterally based triangular vermilion flap but with modifications to the shape and length. The body of the flap is wider than the pedicle to add tissue to the center of the vermilion, and the length is sufficiently elongated to reach the lesser side. Main Outcome Measure: Lip shape was graded on a 4-point scale when patients were 1 year old. Results: Twenty-two patients were treated with the foxtail-shaped vermilion flap (group A) and 27 patients with Noordhoff triangular vermilion flap (group B). Group A had a better lip shape than group B ( P = .006). Conclusions: The foxtail-shaped vermilion flap is useful to reconstruct the median tubercle in asymmetric bilateral cleft lip repair with contralateral lesser form defects.

Objective: To compare carbamazepine pharmacokinetic parameters between obese and lean subjects following the administration of a single 200-mg tablet. Design: Single-dose intervention, open study. Setting: Teaching university hospital. Subjects: Eighteen obese (group A) otherwise healthy subjects, referred to the metabolic outpatient clinic, and 13 healthy lean (group B) volunteers. Inclusion criterion for the obese subjects was a body mass index (BMI = weight/height2) of more than 30 kg/m2. In the obese group, mean ± SD total body weight (TBW), BMI, and percent of ideal body weight (IBW) were 111.4 ± 19.9 kg, 38.8 ± 6.0 kg/m2, and 182.7% ± 30.7%, respectively. These values were significantly greater than the respective values of 63.2 ± 8.3 kg, 22.4 ± 1.6 kg/m2, and 105.8% ± 5.8% obtained in the lean group (p < 0.001). Intervention: Single-dose oral administration of carbamazepine 200-mg tablet (Teril, Taro, Israel). Outcomes: Carbamazepine elimination half-life (t1/2), apparent volume of distribution (Varea/F), and its oral clearance (Clpo/F) were derived from the drug concentration-time curves. Results: Carbamazepine Varea/F and t1/2 were significantly greater in group A than in group B (98.4 ± 26.9 vs. 60.7 ± 8.5 L, respectively, p < 0.001; and 59.4 ± 14.7 vs. 31.0 ± 5.0 h, respectively, p < 0.001), but its Clpo/F was reduced only slightly in obese as compared with lean subjects (19.8 ± 5.2 vs. 23.0 ± 4.6 mL/min, respectively, p = 0.07). Correction for IBW yielded similar results for Varea/F and t1/2, but Clpo/F per kg of IBW was significantly smaller in the obese than in the lean subjects (0.32 ± 0.07 vs. 0.39 ± 0.06 mL/min/kg of IBW, respectively, p < 0.02). Linear correlations were observed between Varea/F and TBW for both group A (r = 0.92, p < 0.001) and group B (r = 0.77, p < 0.002). Conclusions: In comparison with lean subjects, carbamazepine Varea/F is significantly greater in obese subjects and its t1/2 is markedly prolonged. The minor nonsignificant effect of obesity on carbamazepine Clpo/F suggests that in obese subjects the carbamazepine daily dose should be based on IBW, not on TBW.
