Bronchiectasis is a well-known entity where the airways abnormally dilate losing their natural function. Most common causes of non-cytic fibrosis bronchiectasis in the middle age group include secondary immunodeficiency, aspiration, and allergic bronchopulmonary aspergillosis (ABPA). Obstructive foreign body is an uncommon cause of bronchiectasis and is often a missed diagnosis in a localized disease. Foreign bodies can be missed making the diagnosis and treatment more challenging and hence foreign body bronchiectasis should be considered in patients presenting with focal disease. Here we describe a patient with a retained foreign body that was discovered post lobectomy during gross pathological examination of the specimen with no significant aspiration history, non-diagnostic imaging of the chest and negative bronchoscopy.

T cell non-Hodgkin lymphomas (T-NHLs) are aggressive malignancies which have a high risk of life-threatening complications. However, their prognosis in the intensive care unit (ICU) setting has not yet been assessed. We conducted a study including 87 ICU patients either with newly diagnosed T-NHLs or those undergoing first-line therapy admitted between January 1, 2000, and December 31, 2014. The primary subtypes were peripheral T cell lymphoma (PTCL) (n = 41, 47%), anaplastic large-cell lymphoma (ALCL) (n = 13, 15%), and adult T-leukaemia/lymphoma (ATLL) (n = 11, 13%). Six in every ten patients had malignancy-related complications (haemophagocytic syndrome 37%, tumour lysis syndrome 18% and hypercalcaemia 9%), while infections accounted for one quarter of ICU admissions. Nine fungal infections were documented, including six invasive aspergillosis. Urgent chemotherapy was started in the ICU in 59% of the patients, and urgent surgery was required in 13%. ICU and day-90 mortality were 22% and 41%, respectively. Multivariate analysis showed that SOFA score at day 1, age, sepsis and haemophagocytic syndrome were independent predictors of day-90 mortality. Compared to 66 ICU-matched controls with non-Hodgkin B cell lymphomas, patients with T-NHLs had a similar ICU survival. Overall survival rates of patients with T cell NHLs and B cell NHLs were 20% and 46%, respectively (hazard ratio for death associated with T cell NHLs 2.00 [1.12-3.58]). Patients with T cell NHLs had a very poor long-term outcome. Although the high rate of short-term survival suggests that an ICU trial is a reasonable option for patients newly diagnosed for the malignancy, extended stay in the ICU or further readmission should be considered only for highly selected patients who respond to the haematological treatment.

Medical azole antifungals are major compounds used to prevent and to treat invasive aspergillosis (IA). Azole fungicides, called DMI (14-alpha demethylase inhibitors), are also widely used for crop protection and have been reported to be linked to azole-resistant A. fumigatus (aR-Af) development in the environment. The aim of this study was to determine whether or not market gardens that spray DMIs in Eastern France are also affected by the presence of aR-Af. Forty aR-Afs were detected in soils in only two of the four market gardens using DMIs, with 23% (7/30) and 10% (3/30) of soils containing aR-Af. A total of 87.5% of these isolates had the TR34/L98H mutation and 22.5% the TR46/Y121F/T289A mutation on the cyp51A gene. Analyses of residual azole concentrations in soils showed the presence of difenoconazole for up to 2 years after spraying, but only in soils of market gardens where aR-Af was detected. It is very important to identify professional activities that could lead to aR-Af development and to develop preventive measures for at-risk patients living near professional activities using DMIs. We have to better understand why, in some cases, the use of DMI is not linked to aR-Af. Measures should be taken to avoid the use of DMI conferring cross-resistance to preserve the efficiency of human therapeutics.

We report a case of Paragonimus westermani infection simultaneously affecting two separate organs that presented as both a pulmonary cavity and adrenal mass in an immunocompromised host. A 65-year-old male with a previous kidney transplant visited our clinic because of hemoptysis. Chest computed tomography (CT) showed a pulmonary cavity and right adrenal gland mass. The Aspergillus antigen titer in bronchial lavage fluid was elevated and showed positive conversion. It was necessary to differentiate lung cancer with adrenal gland metastasis from a fungal infection with an adrenal gland adenoma. Positron emission tomography CT suggested benign disease, and it was misdiagnosed as pulmonary aspergillosis based on the elevated Aspergillus antigen titer in the bronchial lavage fluid. Owing to the adverse effects of anti-fungal treatment, the patient underwent wedge resection of the lung and P. westermani was confirmed. A careful history revealed that the patient had eaten raw freshwater crabs 3 years earlier, and a test for serum antibodies to P. westermani was positive. Despite treatment with praziquantel, the adrenal mass persisted on 3-month follow-up CT. A right adrenalectomy was performed and a P. westermani infection was confirmed.

New alternative laboratory means are needed to improve the options for antemortem diagnosis of avian aspergillosis. In this study, 3-hydroxybutyrate was measured in plasma samples collected from a cohort of African penguins ( Spheniscus demersus) maintained under human care. Results were interpreted in combination with those of protein electrophoresis and compared with anti- Aspergillus antibody and galactomannan antigen detection. Overall, 3-hydroxybutyrate levels were found significantly increased in Aspergillus-diseased cases versus the control penguin group ( P = 0.002). Mean absolute concentration of β-globulins was increased >20% in samples from infected birds, and α2-globublins were also found to be significantly increased versus clinically normal controls ( P < 0.001 and P = 0.001 respectively). Of note, the α2-globulins were also significantly increased versus penguins with inflammatory (non-aspergillosis) diseases ( P = 0.001). The specificity of 3-hydroxybutyrate, β-globulins, and α2-globulins for aspergillosis was 78.6%, 79.6%, and 92.2%, respectively. Using these measures in tandem resulted in high specificity (>90%) and negative predictive value (≥80%). In contrast, anti- Aspergillus antibody and galactomannan antigen did not distinguish between infected cases and controls ( P > 0.05). This study demonstrates that basic testing in tandem with the new biomarker 3-hydroxybutyrate may provide reliable evidence for the diagnosis of aspergillosis in penguins.

Aspergillosis continues to be one of the most important causes of disease in captive penguins. As such, designing exhibits and holding areas that minimize the risk of aspergillosis is of great interest; however, very little has been published regarding this topic. The goal of this study was to assess total fungal spore loads as well as the loads of Aspergillus spp. encountered in multiple indoor and outdoor microenvironments around the exhibit for a large colony of African penguins ( Spheniscus demersus). Air samples were collected via impaction at the microenvironments on a monthly basis over a 1-yr period. Results of this study indicated seasonal trends in both total fungal spore loads as well as Aspergillus spp. loads, with the lowest levels encountered during January through April. During the warmer, more humid spring, summer, and fall months when outdoor microenvironments experienced the highest fungal loads, the air-handling system and the pleated filters used indoors are thought to have reduced the fungal loads in the indoor microenvironments compared with the outdoor microenvironments. Additionally, surrounding planting beds were thought to contribute to the higher total fungal loads and Aspergillus spp. loads in the outdoor microenvironments. Results of this study are useful in understanding the factors that contribute to Aspergillus spp. loads in areas that house penguins, and can be used in guiding design, construction, and landscaping of penguin enclosures.
