RESUMO
Identification of risk factors for severe outcome of SARS-CoV-2 infection is an important issue in COVID-19 management. Much attention has been focused on comorbidities as well as drugs taken by patients. Usage of proton pump inhibitors (PPIs) appears to potentially influence disease course. These drugs are known to reduce stomach acid and also modulate the immune system. Their use, prior to and during COVID-19 infection, seems to predispose to the development of more severe pneumonia and therefore to a greater risk of mortality. Instead, the use of histamine receptor 2 antagonists (H2RAs) seems to be associated with a better outcome in patients with COVID-19, in terms of symptoms, risk of intubation and death. As PPIs are essential for treatment of many disorders, usage of these drugs should be balanced considering the benefits and risk ratio, in order to guarantee their correct use for the necessary time. It remains to be clarified whether the detrimental effects, in terms of COVID-19 severe outcome, are due to PPIs or to the underlying disease for which they are administered. New controlled-randomized trials are required to better understand their impact in SARS-CoV-2 infections. *Vanvitelli/Monaldi COVID Group: Adriano Cristinziano, Carolina Delle Donne, Cecilia Calabrese, Fabio Perrotta, Filippo Scialò, Francesco Lassandro, Gennaro Mazzarella, Giorgio Paoli, Leonardo De Luca, Maria Galdo, Miriam Buonincontro, Roberta Cianci, Rosalba Donizzetti, Stefano Sanduzzi Zamparelli, Tullio Valente, Vito D'Agnano, Vittorio Bisogni.

Lung cancer is the leading cause of cancer-related death worldwide and majority of patients are diagnosed in advanced/metastatic disease stage. Sites of distant metastases mainly include contralateral lung, lymph nodes, brain, bones, adrenal glands and liver; skeletal muscles metastases (SMMs) are less common. Psoas muscle and diaphragm metastases are mainly found during autopsy, as their involvement commonly is asymptomatic. We report a case of a 60-year-old female, suffering from non-small cell lung cancer (NSCLC), with refractory lower back pain, as expression of malignant psoas syndrome (MPS). MPS is a rare and difficult-to-treat cancer-pain syndrome, unresponsive to majority of analgesic therapy, related to psoas muscle metastasis; it is usually caused by different tumors such as uterus, ovary, bladder, prostate, colon-rectum, lymphoma, melanoma and sarcoma and represents an uncommon finding in NSCLC patients.

Since the beginning of 2020, the new pandemic caused by SARS-CoV-2 and named coronavirus disease 19 (COVID 19) has changed our socio-economic life. In just a few months, SARS-CoV-2 was able to spread worldwide at an unprecedented speed, causing hundreds of thousands of deaths, especially among the weakest part of the population. Indeed, especially at the beginning of this pandemic, many reports highlighted how people, suffering from other pathologies, such as hypertension, cardiovascular diseases, and diabetes, are more at risk of severe outcomes if infected. Although this pandemic has put the entire academic world to the test, it has also been a year of intense research and many important contributions have advanced our understanding of SARS-CoV-2 origin, its molecular structure and its mechanism of infection. Unfortunately, despite this great effort, we are still a long way from fully understanding how SARS-CoV-2 dysregulates organismal physiology and whether the current vaccines will be able to protect us from possible future pandemics. Here, we discuss the knowledge we have gained during this year and which questions future research should address.
RESUMO
OBJECTIVE: Preoperative functional evaluation is central to optimizing the identification of patients with non-small cell lung cancer (NSCLC) who are candidates for surgery. The minute ventilation/carbon dioxide output (VE/VCO2) slope has proven to be a predictor of surgical complications and mortality. Pulmonary rehabilitation programs (PRPs) could influence short-term outcomes in patients with COPD undergoing lung resection. Our objective was to evaluate the effects of a PRP on the VE/VCO2 slope in a cohort of patients with COPD undergoing lung resection for NSCLC. METHODS: We retrospectively evaluated 25 consecutive patients with COPD participating in a three-week high-intensity PRP prior to undergoing lung surgery for NSCLC, between December of 2015 and January of 2017. Patients underwent complete functional assessment, including spirometry, DLCO measurement, and cardiopulmonary exercise testing. RESULTS: There were no significant differences between the mean pre- and post-PRP values (% of predicted) for FEV1 (61.5 ± 22.0% vs. 62.0 ± 21.1%) and DLCO (67.2 ± 18.1% vs. 67.5 ± 13.2%). Conversely, there were significant improvements in the mean peak oxygen uptake (from 14.7 ± 2.5 to 18.2 ± 2.7 mL/kg per min; p < 0.001) and VE/VCO2 slope (from 32.0 ± 2.8 to 30.1 ± 4.0; p < 0.01). CONCLUSIONS: Our results indicate that a high-intensity PRP can improve ventilatory efficiency in patients with COPD undergoing lung resection for NSCLC. Further comprehensive prospective studies are required to corroborate these preliminary results.

UNLABELLED: We report a case of 31 years-old female suffering from complicated giant bulla in the right upper pulmonary lobe. The patient was admitted to our hospital with a radiologic diagnosis of hydro - pneumothorax treated by chest tube in a first time, and later, for prolonged air leaks, by uniportal VATS with a single 4-cm skin incision. We have observed a giant ruptured bulla in right upper lobe, so we have performed bullectomy and mechanical pleurodesis. This case, in our knowledge, represents the first giant bulla resection performed by uniportal VATS. KEY WORDS: Giant bulla, Giant bullous emphysema, Uniportal VATS.

BACKGROUND: Laryngeal cancer is the second most common respiratory neoplasm after lung cancer. Laryngectomy is a well established treatment for larynx cancers which involve relevant anatomic alterations. Spirometry is an essential investigation tool for diagnosis and severity of respiratory diseases, difficult to perform in laryngectomees. METHODS: 43 consecutive laryngectomized patients were enrolled from July 2014 to March 2015. Patients fulfilling inclusion criteria underwent spirometry at baseline assessment and after two days. During the examination, the spirometer was placed directly on the stoma of the patient, through mouthpiece "Spirometry Filter 74". RESULTS: At baseline, 26 eligible laryngectomees correctly performed the spirometry test with mouthpiece adhering to the stoma; 4 patients refused to perform the second spirometry after 2 days. The feasibility of spirometry examination in these patients was 100% despite difficulties in the execution of the test. The Pearson coefficient of reproducibility for FEV1, FVC and Tiffeneau Index was, respectively, 0.98, 0.94 and 0.77. DISCUSSION: Spirometry in laryngectomee patients is a feasible procedure for assessment of respiratory function; despite technical difficulties in the execution of the test, our results underline the reproducibility and repeatability of the spirometry. In conclusion, when performed within dedicated respiratory pathophysiology unit, spirometry is a reliable tool in the assessment and follow up of laryngectomees.

The fibrous tumors of the pleura are rare primary tumors, accounting for 5% of malignant pleural neoplasms, which generally originate from sub-mesothelial mesenchymal tissue of the visceral pleura. These tumours generally exhibit clinical benign behavior although 12% of solitary fibrous tumors can be malignant and have worse outcomes. These tumors are considered "giant" when the lesion > 15 cm. Surgical treatment is the best choice for both benign and malignant neoplasms. We retrospectively analyzed the main case series of giant fibrous tumors of the pleura. In addition we report our experience of a 76-year-old woman treated by pre-surgical embolization involving implantation of vascular plugs. Surgery was successfully carried out without complications; imaging and functional assessment 6 months post intervention demonstrated both the absence of recurrence and improvement of lung function parameters.
RESUMO
UNLABELLED: The solitary fibrous tumour of the visceral pleura is a rare neoplasm that derives from mesenchymal cells adjacent to the mesothelial tissue of pleura. Surgical resection is the treatment of choice in benign lesions and healing resulting in half of malignant. Local recurrence can occur in malignant cases, but it is very rare in solitary benign tumors. It may be a result of an incomplete or conservative surgery, lack of identification of a tumor during the operation or a growth of a synchronous neoplasm independent from that removed. Surgical resection is also burdened with some difficulty as the size of the tumor, the relationship with the adjacent structures and identification of the vascular peduncle. We report a case of 72 years-old male with a sessile left solitary fibrous tumour of the visceral pleura. The mass of 10 x 7 x 5 cm was attached, thanks to large planting base, to lateral basal segment of left lower lobe. The patient was treated by single port video assisted approach with a 4 cm skin incision. This case, in our knowledge, represents the first resection by single port VATS of a sessile SFTP with a large plating base and, more generally, the third SFTP resection treated by single portal access. KEY WORDS: Solitary fibrous tumour, Uniportal VATS.

RESUMO Objetivos: A avaliação funcional pré-operatória é fundamental para otimizar a seleção dos pacientes para cirurgia torácica para tratamento do CPCNP. Uma alta inclinação VE/VCO2 se mostrou um preditor de complicações cirúrgicas e de aumento da mortalidade. Programas de reabilitação pulmonar (PRP) demonstraram aumentar os parâmetros funcionais e os desfechos de curto prazo em pacientes com DPOC submetidos à ressecção pulmonar. O impacto dos PRP na inclinação VE/VCO2 não foi totalmente investigado. Métodos: Avaliamos retrospectivamente 25 pacientes com DPOC consecutivos submetidos aos efeitos de um programa de reabilitação pulmonar de alta intensidade (PRP) na inclinação VE/VCO2. Resultados: Não foram observadas variações significativas nos principais parâmetros espirométricos após o programa de reabilitação de três semanas (pré-reabilitação VEF1 versus pós-reabilitação VEF1 %prev: 61,5 ± 22,0% para 62,0 ± 21,1%, ns; pré-reabilitação DLCO para pós-reabilitação DLCO %prev: 67,2 ± 18,1% para 67,5 ± 13,2%, ns). Por outro lado, o pico de VO2 e a inclinação VE/VCO2 melhoraram significativamente após PRP (pico de VO2 pré-reabilitação para pico de VO2 pós-reabilitação: 14,7 ± 2,5 para 18,2 ± 2,7 mL/kg/min, p < 0,0000001; inclinação pré-reabilitação VE/VCO2 para pós-reabilitação inclinação VE/VCO2: 32,0 ± 2,8 para 30,1 ± 4,0, p<0,01). Conclusão: Documentamos o benefício no desempenho físico de um treinamento de três semanas em um grupo de pacientes com DPOC com um comprometimento funcional notável em parâmetros de esforço. Dados adicionais e mais abrangentes são necessários para esclarecer os mecanismos fisiológicos.
