An experience of surgical non-thoracic emergencies in patients admitted for chronic lung disease is herein presented. Fifty-four patients out of 10457 admitted in the four Departments of Pneumology of the Binaghi Hospital (Cagliari) between 1-1-1985 and 31-3-1993, were referred to our Department of General Surgery due to non-thoracic surgical emergencies. There was a considerable delay in the referral (only 25% of patients within 12 hours from the onset of symptoms): indeed predominant respiratory symptoms, hypoxia and
hypercapnia
made these patients no responsive to symptoms of surgical emergency. Surgical emergencies in causal correlation with respiratory disease (intestinal occlusion due to abdominal
metastases
of lung carcinoma, complicated peptic ulcer) had the worst prognosis (mortality: 52.9%). Those in chance connection, such as acute limb ischemia and preexisting abdominal disease, had a less adverse outcome. Mortality, however, was 37.5%: this datum outlines the role of chronic lung disease in defining operative risk. The authors call attention to three groups of observed patients: 1) three patients were operated on for intestinal occlusion due to unrecognized abdominal neoplasia, that showed itself in the course of hospitalization in the Department of Pneumology for lung metastases; 2) in 3 cases symptoms and signs of acute abdomen were observed without abdominal disease. The cause of acute pseudoabdomen was diaphragmatic pleural or basal pulmonary inflammation; 3) the eight patients with pulmonary embolism were all admitted in the Department of Pneumology with a wrong diagnosis of bronchopneumonia.

Red blood cells from patients with sickle cell disease will sickle under conditions of hypoxemia and acidosis which is a similar milieu found in malignant tumors. While control of tumor angiogenesis has long been a goal of cancer therapy, selective occlusion of tumor blood supply may be achieved by transfusion of sickle cells into patients who suffer
metastatic cancer
. Although this potential therapy has not been previously reported in the medical literature, the concept may have been elusive to medical mainstream thinking because it requires transfusion of diseased cells. For this therapy to be effective, other environmental factors may need to be manipulated such inducing mild hypoxemia or
hypercarbia
(respiratory acidosis) to induce red cell sickling. Preliminary evidence supportive of this therapeutic approach to cancer treatment is provided by case evidence that sickle cell occlusion of a malignant brain tumor (glioma) produced tumor necrosis. Also sickle cells have been successfully transfused into primates. Furthermore, donor blood is crossmatched and transfused into patients suffering from sickle cell disease regularly in clinics and this procedure is associated with acceptable morbidity. Most importantly, animal models of sickle cell disease and cancer currently exist, and this theory could be tried with available technologies including ultrasound detection of vaso-occlusion. While the proposed therapy may not cure
metastatic cancer
, this treatment could prove useful for decreasing the size and perhaps the pain from metastatic tumor burden. Therefore, it is hypothesized that ABO Rh compatible crossmatched sickle cells transfused into patients who suffer
metastatic cancer
under controlled conditions of blood oxygenation and pH will selectively produce vaso-occlusive infarcts in malignant tumors and be a useful therapy. The author hopes for further investigations.

We here report on a 74-year-old man diagnosed with a pT3cN0
BRAF
-mutated and mismatch repair-deficient adenocarcinoma in the colon ascendens and 3 liver metastases. After hemicolectomy, the patient received treatment with the PD-1 inhibitor pembrolizumab. Three weeks later (on day 22), laboratory tests showed leukocytosis and an increase in transaminases; immune checkpoint inhibitor (ICI)-induced hepatitis was suspected and prednisolone therapy was initiated. On day 29, the patient was acutely hospitalized due to dyspnea, somnolence and walking difficulties. Dysarthria, hoarseness, muscle pain and weakness had developed and the dose of prednisolone was increased. Serum levels of lactate dehydrogenase, creatine kinase and myoglobin were increased and ICI-induced myositis was suspected. Antibodies against acetylcholine receptor and titin were present, indicating myasthenia gravis. Eventually, bulbar myopathy developed, including dysarthria and dysphagia, and the patient could no longer attain saturation without oxygen. The patient was transferred to the intensive care unit, intubated and given methylprednisolone, intravenous immunoglobulins and infliximab. The patient developed
carbon dioxide retention
and died on day 39. Microscopical examination of the intercostal musculature, diaphragm, cervical musculature and tongue showed inflammatory infiltration and fibrosis consistent with a pronounced myositis. In the liver, microscopical examination did not show
metastases
from colorectal cancer but instead a hepatocellular cancer. The cause of death was determined as respiratory insufficiency due to polymyositis. In conclusion, ICIs may induce myositis combined with neurological immune-related adverse events. In patients developing muscle weakness and pain under ICI therapy, myositis should be suspected.
