    Abstract A man in his 40s was admitted to his local hospital 6 days after the first vague symptoms of COVID-19. His general condition deteriorated, and he was treated in the intensive care unit but did not require mechanical ventilation. During his recovery, he experienced a cough spell, after which his dyspnoea recurred and rapidly increased. CT pulmonary angiogram showed a 10×18 cm cavitary lesion with an air-fluid level and surrounding atelectasis of the right lower lobe. A one-way valve mechanism had developed, leading to the formation of a pneumatocele. The patient was treated by occlusion of all bronchial segments of the right lower lobe with endobronchial valves, and the pneumatocele was evacuated with a pigtail catheter. The valves were removed 4 weeks after insertion, and the right lower lobe re-expanded. Six months after treatment, the patient had recovered completely and almost regained his former lung function.

    Abstract The objective of the study was to determine the impact of PET uptake on liver metastases on overall survival (OS) after resection of pulmonary metastases in patients who had received liver transplantation (LT) due to unresectable colorectal liver-only metastases. Resection of pulmonary colorectal metastases is controversial. Some hospitals offer this treatment to selected patients, whereas other hospitals do not perform the procedure in colorectal cancer patients who develop pulmonary metastases. All patients included in the LT studies who developed pulmonary metastases as first site of relapse, and had resection of these as first treatment, were included in this report. Metabolic tumor volume (MTV) in liver was derived from the pre-transplant PET examinations. OS from time of resection was calculated by the Kaplan−Meier method. Patients with low MTV (<70 cm3) had significantly longer OS from time of resection of pulmonary metastases compared to patients with high MTV (>70 cm3). Patients with low MTV in the liver had 10-year OS from time of pulmonary resections of 86%. Liver MTV values from pre-transplant PET examinations may predict long OS in colorectal cancer patients with a resection of pulmonary metastases developing after LT. Thus, in selected colorectal cancer patients developing pulmonary metastases resection of these metastases should be the treatment of choice.

    Abstract Background: Multiple endocrine neoplasia type 2A (MEN 2A) is an autosomal dominant syndrome caused by activating germline mutations in the RET (REarranged during Transfection) proto-oncogene. MEN 2A has a strong (>95%) and age-dependent (5-25 years) clinical penetrance of medullary thyroid carcinoma (MTC). Several major studies have analyzed the predictive and prognostic factors for MEN 2A to find indicators that predict the optimal timing of prophylactic thyroidectomy. The aims of this study were to describe all known RET positive MEN 2A patients diagnosed in Norway and to evaluate the clinical course of MTC, as well as its predictive and prognostic factors.
    Methods: This nationwide retrospective cohort study included data for 65 (14 index and 51 screening patients) out of a total of 67 MEN 2A patients with the RET gene mutation who were diagnosed in Norway since 1974. Data were collected by reviewing patient files. The variables analyzed were genotype, phenotype, preoperative basal calcitonin, age at thyroid surgery, central lymph node dissection and nodal status at primary surgery, number of surgical procedures, and biochemical cure. Of the 65 patients, 60 had undergone thyroid surgery. The median follow-up period was 9.9 years. The patients were divided into pre-RET-and RET-era, which included patients who had thyroid surgery before January 1, 1994, and after, respectively.
    Results: In index and screening patients, MTC was found, respectively, in 100% and 45% of cases, central lymph node dissection at primary surgery was done for 64% and 52% of patients, and the median total number of surgical procedures was two (range 1-6) and one (range 1-4). At primary surgery, all patients (n = 13) with lymph node metastases had preoperative basal calcitonin levels ≥68 pg/mL, and all patients (n = 17) without central lymph node dissection and preoperative basal calcitonin <40 pg/mL were biochemically cured. Multivariate analysis showed that preoperative basal calcitonin was a significant predictive factor for MTC superior to age at thyroid surgery when analyzing the entire period (p = 0.009) and the RET-era separately (p = 0.021). Prognostic factors for biochemical cure were preoperative basal calcitonin, central lymph node dissection, and nodal status at primary surgery (p = 0.037, p = 0.002, and p = 0.005) when analyzing the entire period, but only nodal status at primary surgery when the RET-era was considered separately (p = 0.006).
    Conclusions: Preoperative basal calcitonin alone can serve as an indicator for optimal timing and the extent of thyroid surgery for MEN 2A patients that could be considered safe. The results are consistent with previously reported data.
