This case report describes the incredible dislocation of a right ventricular lead 1 month after pacemaker implantation. The lead's tip was found in the subcutaneous fat beneath the left breast. Extraction was uneventful. The key steps in the diagnosis and management of this rare complication are discussed.

Introduction Spontaneous pneumothorax occurs rarely during pregnancy with less than 100 cases reported in the English literature. There is no strong evidence concerning the treatment of spontaneous pneumothorax during pregnancy and labor. The aim of this study is to systematically review all the reported cases and to suggest recommendations for its diagnosis and treatment. Methods A PubMed research was conducted. The following data were collected: maternal age, gestation age (weeks), presence of underlying lung pathology, initial management, definitive management, obstetric outcome, and the complications for the mother and the fetus. Results Eighty-seven cases were identified. The mean maternal age was 27 years (standard deviation [SD] ± 6). The mean gestational age was 25 weeks (SD ± 11.4). In 37.9% of cases, there was no underlying lung disease. In the majority of cases (67.4%), the initial treatment was the placement of a chest tube. In 48% of cases, the pneumothorax was resolved with conservative treatment. Surgical therapy was performed either antepartum or postpartum. In 58.6% of cases, there was a vaginal delivery, spontaneous or instrumental. In three cases (3.4%), there were fetal complications. Conclusion The analysis of the current literature provides low evidence, since there are only case reports and small case series. It is likely that the frequency of this condition is underestimated. However, this analysis permits to draw some conclusions concerning the timing of pneumothorax treatment, the operative strategy, and the mode of delivery to decrease the risk for the mother and the fetus.

Objectives The purpose of this study was to determine the outcome of head and neck squamous cell carcinoma (HNSCC) patients developing lung metastasis. Design Retrospective study. Participants HNSCC patients with lung metastasis treated between 2001 and 2018 were included. Mean outcomes measures Statistical analyses described the relationship between patient survival, treatment efficacy and pulmonary metastasis occurrence. Results One hundred HNSCC patients were included in the study. The median overall survival (OS) was 21 months. The median recurrence‐free survival (RFS) was seven months. Patient survival with only lung metastases was significantly longer compared to patients with lung metastases and lymph nodes involvement or other metastases. Moreover, patients with a single metastasis had longer post‐RFS and OS than patients with multiple metastases. The local control of metastasis was better when patients presented only lung metastases, and it was more effective in single metastasis. The surgery allowed better metastases local control than supportive care or radio and/or chemotherapy. In case of specific therapy, pulmonary resection was associated with a longer post‐RFS and a longer OS compared to supportive care or radio and/or chemotherapy. Conclusions We confirmed, in the current study, the significant survival benefit for HNSCC patients treated by surgery for their pulmonary metastasis. While treatment of multiple metastases required palliative chemotherapy or best supportive care in most of the cases, specific surgical treatment in selected HNSCC patients should be considered.
