Shoulder pain in patients following lung resection

Aim and objective: The purpose of this study was to examine the frequency, influencing factors, and clinical course of shoulder pain in patients following lung resection. Background: Thoracoscopes have been introduced in the surgical treatment of lung cancer, and allow for less invasive surgery with a minimal incision. However, decubitus position-related shoulder pain on the operated side has not yet been investigated. Design: A longitudinal descriptive study. Methods: Patients who underwent lung resection in the decubitus position. Patients were interviewed 2 days before surgery and once daily for 5 days after surgery. Interview items included background data, the concomitant use of epidural anesthesia, operative duration, presence of preoperative shoulder stiffness (excluding shoulder pain), type of surgery, and site of operation. The intensity of pain was approximately 5 on an 11-point numerical rating scale. Descriptive statistics on patient backgrounds were obtained using SPSS Statistics 22 for Windows. Results: Of the 74 patients who underwent lung resection in a decubitus position, 30(40.5%) developed shoulder pain on the operated side. The highest rating occurred 1 day after surgery and decreased over time. The following two factors were found to influence shoulder pain on the operated side: operative duration(Z=-2·63;p=0·01), and presence of preoperative shoulder stiffness(excluding shoulder pain)(χ2＝4·16;p=0·04). Conclusions: This study demonstrated that approximately 40% of patients who underwent lung resection in the decubitus position developed shoulder pain. Relevance to clinical practice: The presence of postoperative shoulder pain was related to both the duration of the operation and to the presence of preoperative shoulder stiffness. Although the shoulder pain resolves within 4 days, it causes the patient additional discomfort and distress. Therefore, further research is needed on positioning for thoracotomy in order to investigate ways to reduce or eliminate this complication of lung surgery

Prospective cohort study of febrile neutropenia in breast cancer patients administered with neoadjuvant and adjuvant chemotherapies: CSPOR-BC FN study

Background As Asians are more vulnerable to febrile neutropenia (FN) than Caucasians, evaluations of FN incidence and risk factors in Asians are important for the appropriate use of primary pegfilgrastim (PEG-G). Patients and methods Japanese breast cancer patients receiving standard adjuvant chemotherapies were prospectively enrolled in multicenter institutions from August 2015 to July 2017. FN was evaluated from 2 treatment policies: true FN (T-FN): ≥37.5 °C, grade 4 neutropenia, mandatory hospital visit (visiting); surrogate FN (S-FN): ≥37.5 °C, oral antibiotic, no mandatory visit (non-visiting). PEG-G was used at the physicians’ discretion. The primary endpoint was FN incidence during all cycles. Multivariate logistic regression analysis was performed to identify T-FN risk factors. Results Of 1005 enrolled patients, 980 women treated with FEC, E(A)C, and TC were analyzed. The FN incidence proportions in all patients were 22.5%, 27.5%, and 33.9% for FEC, E(A)C, and TC, respectively. Those of T-FN were 27.7%, 22.4%, and 36.6%; those of S-FN were 17.3%, 32.4%, and 31.5% with more frequent primary PEG-G usage. The relative dose intensity (RDI) of the 3 regimens was ≥0.85 in both groups. In the analysis of risk factors, TC (odds ratio = 2.67), age ≥ 65 years (2.24), and pretreatment absolute neutrophil count (ANC)/1000 μl (0.8) remained significant. Conclusions FN incidences were above 20% in the 3 regimens, with TC showing the highest. RDI was maintained at a high level in both visiting and non-visiting groups. Patient-related risk factors were age and pretreatment ANC

Ascending Colon Cancer Associated with Dermatomyositis Which Was Cured after Colon Resection

A 76-year-old woman with muscle ache, weakness of the extremities, and skin rash was diagnosed with dermatomyositis (DM). Upon the diagnosis of DM, a systemic survey of malignancy revealed an advanced carcinoma of the ascending colon. The patient underwent right hemicolectomy approximately 2 months after the onset of DM. The symptoms and signs of DM disappeared after the surgery without additional therapy. DM is an idiopathic systemic inflammatory disease characterized by muscle ache, muscle weakness, and skin rash. In some cases, DM develops as paraneoplastic syndrome, and it is assumed that 30% of DM patients have cancer. Symptoms and signs of DM can be attenuated by treatment of the malignancy, and they reappear if the malignancy recurs. It is essential to perform a systemic survey of malignancy in DM patients, and treatment of the malignancy has to precede treatment of DM
