Advent of hepatitis B immunoglobulin (HBIG) as the mainstay of prophylaxis against hepatitis B recurrence after liver transplantation with antiviral drugs has resulted in excellent outcomes for liver transplantation in hepatitis B virus (HBV)-related cirrhosis in the last two decades. However, there is no consensus on a gold standard prophylaxis protocol and several controversies over the duration, dose, and route of administration of HBIG with or without different antivirals exist among liver transplantation centers. We present this review of different prophylaxis regimens including HBIG and antiviral monotherapy, combination of HBIG with antivirals, and withdrawal of HBIG and whole prophylaxis. HBIG monotherapy in either the intramuscular or the subcutaneous form is an accepted choice for prevention of HBV re-infection after liver transplantation in low risk patients. Withdrawal of HBIG monotherapy may be considered but should only occur after transitioning to an oral antiviral therapy such as adefovir, tenofovir, or entecavir. Lamivudine monotherapy may be associated with a higher recurrence rate compared to more potent antivirals. In high risk patients, intramuscular or subcutaneous HBIG in combination with an antiviral, most commonly lamivudine, is currently considered the standard of care. Complete discontinuation of all preventative therapy cannot be recommended at this time and should only be performed in the setting of a clinical trial.

Purpose: To assess the effectiveness of heparin, platelet-rich plasma (PRP), and silver nanoparticles on prevention of postoperative adhesion in animal models. Methods: Sixty males Albino Wistar rats aged 5 to 6 weeks were classified into five groups receiving none, heparin, PRP, silver nanoparticles, PRP plus silver nanoparticles intraperitoneally. After 2 weeks, the animals underwent laparotomy and the damaged site was assessed for peritoneal adhesions severity. Results: The mean severity scores were 2.5 ± 0.9, 2.16 ± 0.7, 1.5 ± 0.5, 2.66 ± 0.88, and 2.25 ± 0.62 in the control, heparin, PRP, silver and PRP plus silver groups, respectively with significant intergroup difference (p = 0.004). The highest effective material for preventing adhesion formation was PRP followed by heparin and PRP plus silver. Moreover, compared to the controls, only use of PRP was significantly effective, in terms of adhesion severity (p = 0.01). Conclusion: Platelet-rich plasma alone may have the highest efficacy for preventing postoperative peritoneal adhesions in comparison with heparin, silver nanoparticles and PRP plus silver nanoparticles.

Objective: Despite the recent use of computed tomography scan and diagnostic laparoscopy, acute appendicitis is still highly misdiagnosed. Timely diagnosis of acute appendicitis is more crucial in children and elderly patients because of vague symptoms and rapid progression to perforation in these age groups, which may result in high rates of morbidity and mortality. The aim of the present study was to find the diagnostic values of procalcitonin and interleukin 6 (IL-6) for diagnosing acute appendicitis in our center. Material and Methods: Patients who were suspected of acute appendicitis and referred to the emergency department of a tertiary care urban hospital in 2016 were enrolled in the study. A 5 mL blood sample was obtained from each patient before appendectomy and was examined for procalcitonin and IL-6. Then the resected specimen of the appendix was studied by a pathologist, and a definite diagnosis was made. Results: Eighty patients including 53 (66.3%) men who underwent appendectomy were enrolled in the study. The diagnosis of acute appendicitis was histopathologically confirmed in 60 (75%) patients including 18, 20, and 22 patients with inflammatory, suppurative, and gangrenous/perforated appendicitis, respectively. The sensitivity and specificity of procalcitonin versus IL-6 for diagnosing acute appendicitis were 65% and 80% vs. 76% and 55%, respectively. The sensitivity and specificity of concurrent procalcitonin and IL-6 for diagnosing acute appendicitis were 95% and 55%, respectively. Conclusion: Our study suggests that parallel measurement of procalcitonin and IL-6 decreases unnecessary negative appendectomies.

Background: Confirmed evidences on superiority of subcuticular suturing compared to interrupted suturing method, in terms of postoperative complications such as wound infection, size of scar, or abscess formation is few. Objectives: The present study aimed to compare absorbable subcuticular suturing supported with Steri-Strips™ to interrupted nonabsorbable suturing method after appendectomy. Methods: In a randomized controlled trial, seventy patients with the diagnosis of acute appendicitis at Besat hospital, Hamadan University of Medical Sciences, Iran in the year 2016 were enrolled in the study and were randomly assigned into two groups. In the case group (n = 35), the wound suturing was done using subcuticular suturing supported by Steri-Strips™ and in the control group (n = 35), suturing was performed using interrupted mattress suture. All patients were visited at postoperative day one, seven, thirty and ninety. Results: The width of the scar and the mean of severity of pain score at postoperative day seven in the case group were significantly

Evaluation of the effectiveness of sodium hyaluronate, sesame oil, honey, and silver nanoparticles in preventing postoperative surgical adhesion formation. An experimental study 1 AbstractPurpose: To evaluate the effectiveness of sodium hyaluronate, sesame oil, honey, and silver nanoparticles in preventing of postoperative surgical adhesion formation. Methods: Forty male Wistar rats were randomly assigned into five groups with eight rats in each group including control, hyaluronate, sesame, honey and silver groups. After two weeks the animals underwent laparotomy and were evaluated by two different blinded surgeons for severity of adhesions based on the two different classification scoring systems including Nair classification and cumulative adhesion scoring scale. Results:The scores of severity of adhesions in the hyaluronate and sesame groups were significantly lower than the control group based on the Nair classification (both P-values = 0.02), however based on the cumulative adhesion scoring scale just the score of severity of adhesions in the hyaluronate group was significantly lower than the control group (P-value = 0.02). In the hyaluronate group the severity of adhesions was decreased by 48% based on the cumulative adhesion scoring scale. Conclusions: Sodium hyaluronate and sesame oil may have a significant effect in preventing postoperative surgical adhesion formation.
