Multiple sclerosis (MS) is a progressive demyelinating disease presenting with a relapsing-remitting course and affects large areas of the brain and the spinal cord. Surgical stress often induces exacerbation of MS symptoms. It is mandatory to prepare the MS patient very carefully for the surgery and anaesthesia with an effective premedication and an effective postoperative analgesia following a safe and minimal-risk anaesthesia management. In recent reports, results of general and regional anaesthesia in MS patients have been discussed. To our knowledge this is the first case report of the use of desflurane anaesthesia in a patient with MS. In conclusion, desflurane anaesthesia is a safe and useful method for MS patients.

Özet Amaç: Bu çalışmanın amacı spinal anestezi ile total diz artroplastisi (TDA) yapılan hastalarda postoperatif 48 saatlik periyotta ultrason (US) kılavuzluğunda tek doz femoral sinir bloğunun (FSB) ağrı kontrolü, morfin tüketimi SummaryObjectives: The purpose of this study is to evaluate the effects of ultrasound (US) guided single-injection femoral nerve block (FNB) spinal anesthesia on pain control, morphine consumption, adverse effects, and patient satisfaction during the postoperative 48-hour period in patients undergoing total knee arthroplasty (TKA). Methods: One hundred four ASA physical status I-III patients undergoing single TKA for degenerative joint disease were enrolled in this clinical study. Patients were randomly distributed into two groups: US-guided single-injection FNB with 40 ml of 0.5% bupivacaine and 1:200,000 epinephrine was administered to Group F (n=51) patients. Preservative-free saline was injected in Group P (n=53) patients using the same method as Group F. Pain scores, morphine consumption, incidences of adverse events, and patient satisfaction were assessed over the course of 48 hours. Results: Group F used significantly less morphine compared with Group P (18.7 mg vs. 39.6 mg) during the first 48 hours after surgery (p<0.001). When compared with group P, the VRS scores both at rest and during movement were significantly lower in Group F at 4,8,12, 24, and 48 hours after TKA (for all comparisons p<0.001). In addition, patient satisfaction was better in Group F than Group P. Conclusion: This study suggests that a US-guided single-injection femoral nerve block following TKA improves patient satisfaction and reduces consumption of morphine during the first 48 hours.

Typhlitis is a special type of enterocolitis that specifically develops in immunosuppressive patients with hematological malignancies. Typhlitis is a common consideration after bone marrow transplantation due to high-dose chemotherapy that is used in conditioning regimens those contain high-dose cytotoxic chemotherapeutic agents. Although there are several studies about typhlitis during chemotherapy or in leukemia patients, there is not enough data evaluating its relationship between stem cell transplant in adults. Therefore, the current study aimed to analyze the possible causes that may lead to the development of typhlitis in hematopoietic stem cell recipient patients. This retrospective study included 210 adult patients who underwent bone marrow transplantation between January 2017 and December 2019. Pediatric patients (patients younger than 18 years of age) were excluded. Patients’ data were evaluated to determine their effects on typhlitis and the mortality risk of the patients with typhlitis. The analysis of the variables was performed using the IBM SPSS Statistics for Windows version 26 (IBM Corp., Armonk, NY).Variables were analyzed at a 95% confidence level and a P value <0.05 was considered significant. Typhlitis developed in 23 (10.9%) transplant patients. Male sex, length of hospital stay, presence of febrile neutropenia, antibiotic and antifungal use, need for switching antibiotics, duration of neutropenia, diarrhea and antibiotic use in days were risk factors for development of typhlitis. It was observed that 100-days mortality was higher in typhlitis group reaching to a statistical significance (P < .05). In multiple logistic regression analysis, presence of mucositis and additional source of infection were determined as independent risk factors for the development of typhlitis in bone marrow transplant patients. This study provides valuable information for bone marrow transplant patients through an analysis of risk factors for the development of typhlitis. According to our results, mucositis and additional bacterial infections were found as risk factors for typhlitis therefore it would be beneficial for clinicians to consider these factors in patient follow-up. However, due to the retrospective nature of our study, prospective studies are needed to investigate risk factors and optimum treatment methods for typhlitis.
