This study demonstrated that dexmedetomidine markedly reduced the oxidative stress in serum, liver, and remote organs induced by hepatic IR injury, and ameliorated the histopathological damage in the liver.

Zinc phosphide has been used widely as a rodenticide. Upon ingestion, it gets converted to phosphine gas in the body, which is subsequently absorbed into the bloodstream through the stomach and the intestines and gets captured by the liver and the lungs. Phosphine gas produces various metabolic and nonmetabolic toxic effects. Clinical symptoms are circulatory collapse, hypotension, shock symptoms, myocarditis, pericarditis, acute pulmonary edema, and congestive heart failure. In this case presentation, we aim to present the intensive care process and treatment resistance of a patient who ingested zinc phosphide for suicide purposes.

Background: Evidence suggests that the effect of 0.12% chlorhexidine (CHX) use for oral care on the development of ventilator-associated pneumonia (VAP) and ventilator-associated tracheobronchitis (VAT) is lacking. Evidence-based approaches to the prevention of VAP and VAT are of paramount importance for improving patients' outcomes. Objectives: This study aimed to (1) compare the effect of 0.12% CHX use for oral care on preventing VAP and VAT with the placebo group, as well as (2) compare its effect on oral health and prevention of oral microbial colonization with the placebo group. Methods: Prospective, single-blinded, randomized controlled trial performed in 2 intensive care units at a hospital. The sample comprised 57 mechanically ventilated adults randomly allocated to the 0.12% CHX group and the placebo group. Barnason's oral assessment guide was used to evaluate the oral health of both groups before oral care during the first 24 hr of tracheal intubation (Day 0) and at Day 2 and Day 3. Oropharyngeal secretion, endotracheal tube aspirate, and nonbronchoscopic bronchoalveolar lavage samples were collected on Day 0 and Day 3. Results: The rate of VAT development was not statistically different between the groups (p = .318). However, a significant difference existed in the rate of VAP development (p = .043). The frequency of oropharyngeal colonization significantly decreased in the 0.12% CHX group compared with the placebo group at Day 3 (p = .001). Conclusion: The use of 0.12% CHX for oral care could be effective for VAP prevention and reducing microbial colonization in mechanically ventilated patients.

Bacground. To investigate the anesthetic management in premature infants with retinopathy of prematurity (ROP) treated with intravitreal bevacizumab (IVB) injections. Methods. A retrospective chart review was performed for the patients with ROP who had IVB injection. Clinical characteristics, demographic variables, anesthetic medications, operation techniques, time intervals, and complications were recorded. Results. Sixty-six eyes of 33 patients (23 males, 10 females) with type 1 ROP who were treated with IVB were included. A total of 66 anesthetic applications were performed. Mean gestational age at birth was 28.3 weeks (range 25–33). Mean birth weight was 1300 g (range 600–1850). Serious ocular and systemic complications were not observed in any infant. Conclusion. Inhalation anesthesia with sevoflurane during IVB treatment in premature infants with ROP may be appropriate for anesthetic management.

Acute appendicitis within hernia sac termed Amyand's hernia was described firstly by Claudius Amyand. It has been approximately found in 1 % of cases of inguinal hernias. In this study, we reported a 24 years old man diagnosed with inguinal hernia, which was found appendix vermiformis in the sac of hernia intraoperatively, the other name Amyand's hernia. Diagnosis of Amyand's hernia is difficult preoperatively and is a rare form of inguinal hernia.

A 9-year old male patient was admitted to our clinic for circumcision. Physical examination revealed a mass in the prepuce. After excision of the mass, histopathological examination was consistent with a mucoid cyst of the penile skin, which has been rarely reported. Pathologists and clinicians dealing with genitourinary system pathology should be familiar with this rarely encountered entity.

The superficial cervical plexus block (SCPB) is utilized in pediatric patients to perform certain surgical procedures, but there is no evidence supporting its use in hemodialysis catheter placement. We evaluated the analgesic effectiveness, intraoperative complications, and patient satisfaction associated with SCPB for pediatric patients in renal failure undergoing emergent dialysis catheterization. A total of 52 patients ranging from 1 to 17 years old that required emergent dialysis catheter placement and received SCPB were included in this study. During the catheterization, intraoperative pain scores, requirement for additional analgesia, catheterization access site, and intraoperative complications were recorded. The Children's Hospital of Eastern Ontario Pain Scale (mCHEOPS) was used to determine pain ratings during skin puncture with the needle, skin dilatation, and securing the catheter with stitches. The patients had an average age of 8.46 ± 5.3 years. The preferred catheterization entry site was through right internal jugular vein, which was achieved in 80.7% of patients. However, 19.3% of patients required access through the right subclavian vein. The average mCHEOPS score during skin puncture was 1.4 ± 0.5, and the mean mCHEOPS score was 2.3 ± 0.6 for skin dilatation. Finally, the average mCHEOPS score while securing the catheter with stitches was 1.3 ± 0.4. No patient required fentanyl for additional analgesia. No intraoperative complications occurred. The benefits gained from using SCPB performed by an experienced anesthesiologist for hemodialysis catheter placement include providing sufficient analgesia and optimal surgical conditions while avoiding the complications associated with general anesthesia for pediatric patients with renal failure.
