Comparison of C-MAC vs. McGrath video laryngoscopes on glottic exposure and endotracheal intubation success with stylet usage in obese patients.

OBJECTIVE: Cases of obesity are rising in parallel with the number of obese patients scheduled for anesthesia in which difficult airway is encountered. Video laryngoscopes (VL) have emerged as a popular device for the management of patients with difficult airway. The present study compares the success rate of intubation in obese patients using stylet in the ramped position using either a McGrath or C-MAC VLs. PATIENTS AND METHODS: Class II/III obese patients who were intubated with either McGrath (Group M, n=50) or C-MAC (Group C, n=50) laryngoscopes were assessed for the presence of difficult airway using the Difficult Airway Assessment tool, the Airway Difficulty Score and the Total Airway Score. The intubation attempts were made after the best glottic view, direct and indirect Cormack-Lehane (CL) score, and intubation time were recorded. In the event of failure, a further intubation attempt was made using a styled, and the intubation time was again recorded. If the intubation failed again, a third attempt was made using a C-MAC D-Blade. The Intubation Difficulty Scale score was recorded after the intubation. RESULTS: There was no statistically significant difference between groups in terms of demographic data, the number of patients with decreased CL score, the number of attempts required for intubation, or the first and second intubation time. The ADS Score, TAS Score, CL Score DL, and CL Score IN were found to be important risk factors for a second intubation requirement, and the cut-off value was found to be 8.50 for the ADS Score and 4.50 for the TAS Score in these patients. In the 38 patients who required a second intubation attempt, the procedure was successful in all, but one patient required a third attempt of intubation with C-MAC D-blade. CONCLUSIONS: Both McGrath and C-MAC were effective and comparable for best glottic view with no failed intubation. It was concluded that regardless of the type of video laryngoscope used, the use of a stylet in the first intubation attempt increases the success of intubation.

Coronavirus disease 2019 re-infection: first report from Turkey.

There are concerns about the possibility of SARS-CoV-2 reinfection and recently, a patient with SARS-CoV-2 re-infection (or COVID-19) confirmed by epidemiological, clinical, serological and genomic analyses have been published. We have noticed another patient with SARS-CoV-2 re-infection based on clinical and laboratory studies: A 23-year-old woman presented to her hospital with fever (39°C), chills, fatigue, cough, headache, sore throat, muscle and joint pain on April 9, 2020. On examination, oropharynx was mildly hyperemic, and chest auscultation was normal. SARS-CoV-2 PCR from nasopharyngeal specimen was ordered. She was given isotonic saline and acetaminophen and prescribed azithromycin and acetaminophen and sent home for isolation. SARS-CoV-2 PCR was reported positive and she was given hydroxychloroquine for five days. She improved in 10 days and PCR studies on April 22, and April 27 remained negative. On 4 August 2020, she was re-admitted with fever (38.7°C), chills, fatigue, loss of appetite, taste and smell loss, muscle and joint pain. On examination, oropharynx and chest auscultation were normal. SARS-CoV-2 PCR was reported positive and she was prescribed hydroxychloroquine, acetaminophen and sent home for isolation again. She improved in one week (taste-smell loss improved in 10 days) and on follow-up visit after 14 days, she was doing well. PCR was negative on 17 August 2020. Her anti-SARS-CoV-2 antibodies were negative on 17 August 2020 and slightly positive (2.14 signal-to-cutoff) on 29 August 2020. Previous report from To et al. [Clin Infect Dis. 2020;ciaa1275. doi:10.1093/cid/ciaa1275] showed that viral genomes from first and second episodes belonged to different clades/lineages. They described second episode of asymptomatic infection occurred 142 day after the first symptomatic one. Our patient is the first report, describing two symptomatic episodes 116 days apart. We conclude that as the patients recovered from COVID-19 increases, increased awareness may delineate the characteristics of re-infection.

Characteristics of Turkish children with Type 2 diabetes at onset: a multicentre, cross-sectional study.

AIMS: To describe the baseline clinical and laboratory findings and treatment modalities of 367 children and adolescents diagnosed with Type 2 diabetes in various paediatric endocrinology centres in Turkey. METHODS: A standard questionnaire regarding clinical and laboratory characteristics at onset was uploaded to an online national database system. Data for 367 children (aged 6-18 years) newly diagnosed with Type 2 diabetes at 37 different paediatric endocrinology centres were analysed. RESULTS: After exclusion of the children with a BMI Z-score < 1 SD, those with genetic syndromes associated with Type 2 diabetes, and those whose C-peptide and/or insulin levels were not available, 227 cases were included in the study. Mean age was 13.8 ± 2.2 (range 6.5-17.8) years, with female preponderance (68%). Family history of Type 2 diabetes was positive in 86% of the children. The mean BMI was 31.3 ± 6.5 kg/m2 (range 18.7-61) and BMI Z-score was 2.4 ± 0.8 (range 1-5). More than half (57%) of the children were identified by an opportunistic diabetes screening due to existing risk markers without typical symptoms of diabetes. Only 13% (n = 29) were treated solely by lifestyle modification, while 40.5% (n = 92) were treated with metformin, 13% (n = 30) were treated with insulin, and 33.5% (n = 76) were treated with a combination of insulin and metformin initially. Mean HbA1C levels of the insulin and combination of insulin and metformin groups were 98 (11.1%) and 102 mmol/mol (11.5%), respectively, and also were significantly higher than the lifestyle modification only and metformin groups mean HbA1C levels (70(8.6%) and 67 mmol/mol (8.3%), respectively). CONCLUSIONS: An opportunistic screening of children who are at high risk of Type 2 diabetes is essential, as our data showed that > 50% of the children were asymptomatic at diagnosis. The other important result of our study was the high rate of exclusion from the initial registration (38%), suggesting that accurate diagnosis of Type 2 diabetes in youth is still problematic, even for paediatric endocrinologists.

Health-related Quality of Life of Liver Donors: A Prospective Longitudinal Study.

Living donor liver transplantation is a widely accepted option to treat liver diseases in several indications. Risk of liver donation is being discussed and quality of life of donors is also studied. Changes and the change pattern of quality of life were analyzed in this prospective longitudinal study. PATIENTS AND METHODS: Fifty-five donors were included. The Medical Outcomes Study Short Form 36 (SF-36) was fulfilled either in-person or during a telephone interview each donor preoperatively and at the end of the third, sixth, and 12th months. RESULTS: Physical subdomain scores of SF-36 decreased significantly in the third postoperative month compared to preoperative score. The scores recovered in the sixth postoperative month, except for the bodily pain domain. The pain score recovered at the end of the 12th month. While social functioning score among mental subdomains of SF-36 temporarily decreased and recovered at postoperative 12th month, other mental subdomain scores and mental composition summary scores did not show a significant change. CONCLUSION: The quality of life of living liver donors is not permanently affected by donation. There are well-defined changes in the physical aspects of the quality of life that all seem to recover within 1 year. Donors should be preoperatively informed about this temporary change as well as complications.

Single stapler technique in laparoscopic donor nephrectomy.

BACKGROUND: Laparoscopic donor nephrectomy (LDN) is usually performed with at least 2 separate vascular staplers for division of the renal artery and vein. However, we used a single stapler regardless of the number of renal arteries and veins. Furthermore, the graft was quickly retrieved by hand without using an extraction bag using our technique. Herein we have presented our experience with LDN of grafts with single or multiple renal arteries and/or veins using a single stapler and hand removal. METHODS: We reviewed demographic data, operative and warm ischemia times, postoperative complications, and graft function. RESULTS: Between December 2005 and September 2009, we performed 85 cases with 1 renal artery (group LDN-1), 8 cases with two renal arteries (group LDN-2), and 5 cases with 3 or more renal arteries (group LDN-3). The demographic data among the groups were similar. The mean operative time was significantly longer among groups LDN-2 (100.3 ± 9.5 minutes) and LDN-3 (120.6 ± 10.3 minutes) compared with LDN-1 (76.1 ± 9.3 minutes; P < .001). Similar results were observed with respect to warm ischemia times. There were no significant differences related to graft function and outcomes among these groups. CONCLUSION: The single stapler and hand removal technique was safe, technically feasible, and cost effective regardless of the number of renal arteries and veins. This technique removes the necessity of additional staplers and extraction bags, lowers the operative and warm ischemia times, and thus decreases the cost.

Pure laparoscopic versus open live donor nephrectomy: evaluation of health survey and graft functions.

BACKGROUND: Laparoscopic donor nephrectomy (LDN) has become the gold standard in many kidney transplantation centers seeking to increase the number of potential live donors. This study was designed to compare the health surveys and graft functions between LDN and open donor nephrectomy (ODN). METHODS: We retrospectively analyzed all patients who underwent donor nephrectomy between December 2005 and September 2009 who had at least 1 year of follow-up. We reviewed demographic data, operative time, warm ischemia period, graft function, and quality of life. RESULTS: Among the 132 cases, 98 were pure LDN and 34 were ODN. Demographic data were similar in both groups. Operative times were significantly longer in the ODN group but warm ischemia times significantly longer in the LDN group. However, graft functions were similar in both groups. There was 1 graft loss due to arterial thrombosis of the transplanted kidney among the LDN group. Short-Form 36 health survey scores were similar except for the role-physical subscale. CONCLUSION: Although we failed to observe a significant difference between ODN and LDN as far as the quality of life and graft functions were concerned, the previously documented advantages of laparoscopy with similar operative results suggest? LDN to be the gold standard for this procedure in our institution.

Living-donor hepatectomy.

BACKGROUND: Organ transplantation from deceased donors is still far below the need. Because of this deficiency, liver transplantations are performed mostly from live donors in many transplant centers in our country. Living-donor liver transplantation (LDLT) has evolved dramatically over the past decade. The aim of this study was to present our clinical experience with living-donor hepatectomy. METHODS: We retrospectively analyzed all patients who underwent donor hepatectomy between March 2000 and September 2010. We reviewed demographic data, operation type, operation and cold ischemia times, duration of hospital stay, and postoperative complications. RESULTS: During the study period, 140 living donors underwent operations for liver transplantation. We performed 108 right hepatectomies, 17 left hepatectomies, and 15 left lateral hepatectomies. The mean age of the donors was 30.8 years. There was no operative or postoperative mortality. Overall morbidity rate was 13.57% (n = 19). Nine patients had biliary leakages, 4 biliomas; 2 urinary tract infections, and 1 each inferior vena caval injury, pneumonia, portal vein thrombosis, and acute tubular necrosis. Reoperation was not required in any of these patients. CONCLUSIONS: Living-donor liver transplantation is a valuable alternative for patients awaiting a cadaver organ. Live-donor hepatectomy can be performed with low morbidity. The greatest disadvantage of this procedure is the risk of the surgical operation for the individual who will experience no medical benefit from this procedure.

Do we still need to restrict preoperative fluid administration in ambulatory anorectal surgery under spinal anaesthesia?

BACKGROUND: This study was undertaken to determine the effect of a restricted versus a standard intravenous fluid regimen on urinary retention and readiness for discharge after surgery for benign anorectal disease. METHODS: A total of 41 ASA I-II patients were randomized into a standard fluid regimen group (group S, n=21) or a restricted fluid regimen group (group R, n=20). Spinal anaesthesia was performed with hyperbaric ropivacaine. Haemodynamic variables were noted. Hypotension, headache, analgesia requirement, nausea and vomiting, thirst and urinary retention were evaluated postoperatively. The Mann-Whitney U and chi-squared tests were used. RESULTS: Patient demographics were comparable between the groups. The area under heart rate versus time curve was higher in group R than in group S (p=0.002). Additional fluid and ephedrine requirements were similar between the groups. First voiding time was longer in group R (p=0.045). CONCLUSION: In minor anorectal surgery under spinal anaesthesia with ropivacaine, standard fluid regimen provides stable haemodynamic variables without urinary retention.
