ABSTRACT

BACKGROUND: Actinomycosis by Actinomyces meyeri is rare and scarcely reported in the literature. The lung is the main organ involved. Penicillin and amoxicillin are the first-choice treatments. Surgery is indicated when empyema and abscesses are resistant to medical treatment. CASE PRESENTATION: We report an underdiagnosed case of pleural empyema due to A. meyeri in a patient with closed chest trauma. The patient, a male, 47 years old, presented with a dry cough, thoracic pain, and dyspnea a month after the trauma. A chest X-ray showed a left lower lobe pleural effusion, so he was subjected to a thoracentesis, leading to a partial re-expansion of the left lung. The patient also complained about gum discomfort; thus, a dental x-ray scan was taken, which showed the presence of vertical bone resorption in a periodontal pocket. The patient was treated with levofloxacin 500 mg orally once a day, which was continued for 15 days after discharge. Two months after the accident, he presented again with intermittent fever, a worsening cough, and dyspnea. A CT scan showed thickening of the left pleura and a loculated pleural effusion with partial collapse of the left lower lobe. A decision was made to refer the patient to the Thoracic Unit to undergo surgery via a left thoracoscopic uniportal approach. The lung was thoroughly decorticated, and the purulent fluid was aspirated. The postoperative course was uneventful. Cultures showed the growth of Actinomyces meyeri, which is sensitive to imipenem and amoxicillin. The patient started a proper antibiotic regimen and, whenever possible, was discharged. At 12 months follow-up, a chest X-ray showed a complete resolution of the left pleural effusion with complete re-expansion of the left lung. CONCLUSIONS: Although rare, Actinomycetes infections must be considered especially in front of non-solving empyema or severe pneumonia of unknown cause because in the majority of cases, with the proper treatment, the restitutio ad integrum is possible.

ABSTRACT

The robotic approach in the treatment of thymus diseases has been described in many papers, but few studies have compared the early outcome of patients after robotic and open transsternal procedure. Our study aims to confirm the non-inferiority of the robotic technique in terms of feasibility, safety and postoperative patient recovery compared to the open standard. This is a retrospective cohort study in which we compare 114 patients who underwent thymectomy for a thymus disease at our thoracic surgery unit. Our robotic surgery programme started in February 2012 with the treatment of mediastinal diseases. Since then, we have performed 57 robotic thymectomies (Group A). This series was compared with 57 patients who underwent open thymectomies (Group B) performed before 2012, and all were properly matched through a propensity score. Hospital and ICU stay, postoperative pain, use of painkillers, operative time and complications rate were analysed. Postoperative pain, evaluated through the Visual Analogue Scale (VAS), was significantly lower in the robotic surgery group (p < 0.001), which was associated with a trend to lower use of painkillers in Group A, although it was not significant (p = 0.06). No statistical differences were observed between the two groups in terms of ICU stay (p = 0.080), although the total hospital stay was significantly longer in Group B (p = 0.003). No statistical differences were observed in operative time (p = 0.492) and complications rate (p = 0.950). The robotic-assisted technique showed the same operative time and complications rate compared with open surgery, thereby confirming its safety and feasibility in myasthenic patients as well as in Masaoka I-II thymomas. The lower postoperative pain and the shorter hospital stay associated with prompt mobilisation and faster chest drainage removal showed the great advantage of the minimally invasive robotic approach in these patients.

ABSTRACT

BACKGROUND: Penetrating neck and chest trauma is a very common entity in emergency medicine that usually requires surgical treatment. Our case report illustrates the case of a 27-year-old Arabian man with hemopneumothorax associated with pneumomediastinum due to an unusual occupational injury. CASE PRESENTATION: A metal sliver, coming from an axe using for wood chopping, penetrated the neck of a 27-year-old Arabian man in the left supraclavicular region mimicking a gun bullet; the entrance hole was at the left pleural dome where the sliver had just penetrated the apex of the lung passing through the upper lobe of his left lung creating an exit wound in the dorsal segment of the same lobe arriving in the posterior thoracic wall. Biportal video-assisted thoracic surgery was performed to remove blood clots and the unusual foreign body.  CONCLUSION: In the literature, there are several case series about this topic, with some of them reporting unusual foreign bodies that lead to penetrating trauma. However, to the best of our knowledge, no cases like the one we have reported are described in the current literature.

ABSTRACT

BACKGROUND: To evaluate the effect of first-time and eventual reiterative surgery on overall survival (OS) and disease-free survival (DFS) in Caucasian patients affected by an invasive adenocarcinoma (ADC) with at least another ground-glass opacity (GGO). METHODS: We analysed 47 patients operated on for lung ADC, identified as main cancer (MC), with at least one synchronous GGO, from January 2003 to March 2017. Characteristics associated with the evolution of GGOs were investigated with logistic regression and overall and DFS were evaluated with Kaplan-Meier method. RESULTS: Forty-two (89%) patients received an anatomic resection of the MC, 5 patients were treated by a single or multiple wedge resections. In total, 9 (19.1%) patients had all the lesions resected undergoing simultaneous resection of ipsilateral GGOs at first surgery while the remaining 38 (80.9%) patients still had at least one GGO that was followed up by serial CT scan. At the median follow-up of 41 months, GGO evolved in 16 (42.1%) patients. The presence of solid component at the initial CT scan was the only risk factor for evolution of the GGO. Thirteen patients underwent surgical resection showing an invasive ADC in 9 patients, MIA in 3 and AIS in 1. New GGOs developed in 7 (14.9%) patients, in which three underwent surgery showing the presence of solid ADC, MIA and AAH. OS rate at 5 years was 97.4%. DFS at 3 years was 82% and was significantly influenced by the stage of MC. CONCLUSIONS: Patients affected by an invasive ADC with at least another GGO nodule enjoy good OS and DFS with a surgical reiterative approach. Part-solid GGO is associated with GGO progression requiring treatment, but OS is not influenced by the new onset or evolution of GGOs. DFS is affected by the stage of the MC which dictates the treatment strategy.

ABSTRACT

BACKGROUND: In the treatment of malignant pleural mesothelioma the Hyperthermic Intra THOracic Chemotherapy (HITHOC) can improve the efficacy of pleurectomy and decortication with a local cytotoxic effect. However its biological impact in patient's hemodynamic and microcirculatory changes were rarely investigated. Aim of this study is to describe our experience with HITHOC after pleurectomy and decortication evaluating the role of sublingual video-microscopy in assessing the microcirculatory changes in the perioperative period. METHODS: This is a prospective and observational study concerning 10 consecutive patients undergoing extended P/D followed by HITHOC. These patients underwent sublingual microcirculatory monitoring, which was adopted as a routine procedure since 2012. Haemodynamic parameters were collected at eight consecutive times: the day before surgery (T1), induction of anaesthesia (T2), surgical phase before HITHOC beginning (T3), 5 and 30 minutes after HITHOC start (T4 and T5, respectively), 5 minutes from HITHOC end (T6), after the admission in ICU (T7), at discharge from the ICU (T8). Cardiac output (CO) was calculated with MostCare. Systemic vascular resistance (SVR), oxygen delivery (DO2), and oxygen extraction rate (O2ER) were calculated using standard formulas. Arterial blood pressure and central venous pressure (CVP) were obtained with standard arterial and venous catheters. At the same times we assessed the sublingual microcirculation with Sidestream Dark Field technique. RESULTS: Hemodynamic and microcirculatory data were collected in 10 patients, 8 male and 2 females (mean age 68.6±9.0, and body surface area of 1.9±0.1 m2). All patients had arterial hypertension, and one patient had diabetes. The mean arterial pressure significantly decreased at T2, with respect to T1 (P=0.05). CO, CVP, DO2, O2ER, and ScvO2, did not change significantly over the time. All patients needed infusion of noradrenalin from T4 to T6. TVD significantly decreased from T1 to T3, T5, and T8. Similarly, PVD significantly decreased from T1 to T3 and T8, and MFI from T1 to T6 and T8. PPV and HI did not change over the study period. No correlation was found between hemodynamic parameters (MAP, CO, CVP, DO2, O2ER, ScvO2) and microcirculatory data (TVD, PVD, PPV, MFI, HI), at any time of the study. CONCLUSIONS: In patients who receive HITHOC the fluid load can reduce the microvascular impairment restoring the normal tissue perfusion. This process takes days but is most evident in the first 72 h. The use of colloid and blood transfusion is much more effective in restoring microcirculation and reducing tissue damaging.

ABSTRACT

BACKGROUND: The aim of this study was to assess the prognostic significance of Mib1 expression, Mitosis (Mi) and Apoptosis (Ai) in residual tumour cells after induction chemotherapy in surgically resected IIIA-N2 patients. METHODS: Between January 2002 and November 2008, we reviewed 50 consecutive patients (39 males) with histologically proven stage IIIA-N2 non-small cell lung cancer (NSCLC), who underwent radical resection following induction chemotherapy. Five-year survival in the series was evaluated in relation to lymph node downstaging, histology, extent of resection, number of chemotherapy cycles, pT status, sex and age. It was then also evaluated in relation to the proliferative indexes (Mi, Ap and Mib 1 expression), dividing the patients into two groups according to whether they were above or below the 50th percentile for each parameter. The associations between mortality and the abovementioned prognostic factors were explored using the Kaplan-Meier method, the log-rank test, and Cox regression analysis. RESULTS: The monovariate analysis confirmed the positive prognostic role of lymph node downstaging in terms of 5-yr survival: 31% vs. 12% (P=0.018). However Mi and Mib1 expression under the 50th percentile were also associated with better 5-yr survival: respectively 46% vs. 5% (P=0.007) and 40% vs. 6% (P=0.017). Neither apoptosis nor the other prognostic factors showed any statistical impact on long-term survival. The multivariate analysis showed Mi to be an independent prognostic factor (P=0.005). CONCLUSIONS: Although lymph node downstaging has been considered the principal prognostic factor after induction chemotherapy and surgical resection, Mi and Mib1 expression in residual tumor can predict long-term survival more accurately.
