Review[Hypersensitivity Pneumonitis - an important differential diagnosis of infiltrative lung diseases].
Hypersensitivity pneumonitis (HP) is an inflammatory and/or fibrotic disease of the lung parenchyma and terminal bronchioles caused by an allergic reaction to inhaled antigens. The immune response following antigen exposure results in lymphocytic inflammation as well as granuloma formation. The typical histologic pattern of HP consists of cellular interstitial pneumonia, cellular bronchiolitis, and epithelioid cell granulomas. ⋯ The diagnosis of HP is made by high-resolution computed tomography (HRCT) of the lung, evaluation of possible antigen exposure, and bronchoscopy with bronchoalveolar lavage and, if necessary, forceps biopsy. If the diagnosis is inconclusive, transbronchial cryobiopsy or surgical lung biopsy may need to follow. A multidisciplinary board is critical in making the diagnosis.

Review[Asthma-COPD-Overlap - diagnostic and therapeutic management].
Asthma-COPD Overlap (ACO) is a fuzzy and controversial term intended to characterize patients who have characteristics of asthma and COPD. Since there is no uniform definition, the information on prevalence varies considerably. There is no special diagnostic algorithm and no clear therapy recommendations, as ACO is underrepresented in therapeutic studies. The current clinical consequence of this dilemma should be to differentiate the leading obstructive airway disease asthma or COPD and to treat the predominant phenotype.

Hepatocellular carcinoma (HCC) is the fifth most common cause of cancer with an increasing incidence. The major HCC risk factor in 80 % of all patients is liver cirrhosis followed by chronic hepatitis B infection or non-alcoholic steatohepatitis (NASH) in non-cirrhotic HCC patients. In early BCLC stages curative treatment applying liver resection, liver transplantation or local ablation is feasible, but, despite increased usage of surveillance programmes two-thirds of HCC patients are diagnosed in advanced BCLC stages. ⋯ In fact, major advances in HCC therapy concern medical treatment with the implementation of immunotherapy. The combination of atezolizumab with bevacizumab comprises the new first-line treatment in BCLC stage C. Tyrosine kinase inhibitors (TKI) are indicated in case of contraindications or as second line therapy.

A 59-year-old woman presented for an endocrinological evaluation of recurrent spontaneous hypoglycemia. The complaints always regressed after carbohydrate intake. Due to classic congenital adrenal hyperplasia, the patient received substitution therapy with hydrocortisone for decades. ⋯ In addition to endogenous hyperinsulinism, a disturbance of the contrainsulinergic hormones can also be responsible for spontaneous hypoglycemia.The MMTT and the 72-hour fast test should be used for diagnosis. It is important to ensure that hormone analysis is carried out immediately in hypoglycemia. The ratio of insulin, C-peptide and proinsulin to blood glucose and the constellation of counter-regulatory hormones such as cortisol, ACTH, growth hormone, Insulin-like growth factor 1 (IGF-1) and catecholamines can provide information about the etiology of hypoglycemia.

[Functional characterization of patients with isolated post-capillary or combined post-capillary and pre-capillary pulmonary hypertension].
The World Conference on PH recommended differentiation of isolated postcapillary (Ipc) and combined post- and precapillary (Cpc) PH according to pulmonary vascular resistance alone. The aim of this study was the haemodynamic and functional characterization of patients diagnosed IpcPH and CpcPH according to the current recommendation of the latest World Symposium on Pulmonary Hypertension (PH) with an exploratory data analysis. ⋯ Although CpcPH patients showed higher values of mPAP and PVR functional capacity was not worse than in patients with IpcPH. In patients with PH due to left heart disease an elevated RA/LA ratio may indicate CpcPH and invasive diagnostic work-up should be considered.
