Afghanistan is in a military conflict lasting more than 20 years and according to recent political development, in a downhill spiral towards a failed society. This scenario faces the question of the usefulness of international medical aid, especially morphological diagnostics in crisis situations. On the basis of ten years of experience from a telemedicine project, need, feasibility and results in Afghanistan will be discussed.

Methods: The authors present the analysis of a breast disease register consisting of diagnostic cases from Mazar e Sharif and Herat in 2018 and 2019. The study comprises a total of 567 cases, which were presented to experts via telemedicine for final diagnosis.
Introduction: We describe the use of telepathology in countries with restricted resources using two diagnosis assistance systems (Isabel and Memem7) in addition to the diagnoses made by experts in pathology via the iPath-Network.
Methods: A total of 156 cases, largely from Afghanistan, were analysed; 18 cases had to be excluded because of poor image quality.
Results: Of the remaining 138 cases (100%), a responsible physician provided a tentative diagnosis for 61.
Background: The iPath telemedicine platform Basel is mainly used for histological and cytological consultations, but also serves as a valuable learning tool.
Aim: To study the level of accuracy in making diagnoses based on still images achieved by experienced cytopathologists, to identify limiting factors, and to provide a cytological image series as a learning set.
Method: Images from 167 consecutive cytological specimens of different origin were uploaded on the iPath platform and evaluated by four cytopathologists.
Objective: In this study, the efficiency of telemedical consulting with regard to fine needle aspirates from space-occupying lesions (SOLs) of the liver is investigated for the first time.
Study Design: The study includes fine needle aspirations from 62 patients, 33 with hepatocellular carcinoma (HCC) and 29 with non-hepatic tumors. Using the Internet-based iPath system, the initial pathologist submitted 1-8 images from smears and cell block sections.
We present a unique case of infectious mononucleosis attended with transient asymptomatic BK virus (BKV) manifestation in the urine of an immunocompetent caucasian boy without kidney dysfunction. The urine sediment showed abundant decoy cells initially misdiagnosed as malignant cancer cells. This case demonstrates that the occurrence of polyoma-BKV bearing decoy cells is self-limiting and not necessarily associated with overt kidney disease in an immunocompetent child.

The aim of our study was to evaluate the value of cytology and chromosomal aberrations detected by fluorescence in situ hybridization (FISH) in predicting failure to BCG therapy. Sixty-eight patients with NMIBC were prospectively recruited.

Aim Of The Work: We prospectively evaluated the influence of BAL pre-lavage and the impact of bronchial contamination on BAL differential cell count in 108 BAL specimens obtained from patients with histologically confirmed sarcoidosis.
Background: Equivocal atypia in respiratory cytology can be a diagnostic challenge. In such cases fluorescence in situ hybridization (FISH) may be used for the analysis of chromosomal aberrations and often allows a reliable distinction of benign and malignant cells.
Methods: An online picture gallery of 30 respiratory cytologic preparations comprising 23 specimens with equivocal cytology as well as 5 positive and 2 negative controls was prepared (www.
Urinary cytology is limited by high interobserver variability in the evaluation of cells with little atypia. We set up an online quiz on urinary cytology and tested the performance of 246 international participants. The quiz consisted of still images of 42 urinary specimens with equivocal morphologic features and 10 control cases with an unequivocal cytologic diagnosis.

Methods: Tissue microarrays (n=487) were used to immunohistochemically analyse expression of Maspin and TP53. Cytoplasmic and nuclear expression of Maspin was scored on the basis of the percentage of positive tumour cells.
The aim of the present study was to explore the diagnostic usefulness of the multitarget fluorescence in situ hybridization (FISH) test, LAVysion (Vysis, Downers Grove, IL), for the detection of lung cancer cells in cytologic specimens. Specimens from bronchial washings, bronchial brushings, and transbronchial fine-needle aspirates (TBNAs) from 100 patients with suspected lung cancer and from a control group of 71 patients with nonneoplastic lung disorders were analyzed. FISH positivity was defined as more than 5 cells with gains of at least 2 chromosomes or gene loci.

DNA image cytometry (ICM) and fluorescence in situ hybridization (FISH) have been suggested as ancillary tools. The goal of the current study was to compare the diagnostic value of DNA image cytometry and FISH for the noninvasive detection of urothelial tumors in voided urine.

New-Sternheimer and Papanicolaou staining were used to differentiate cells in urine. We also employed an immunocytochemical technique for further identification of exfoliated cells.

Summary Background Data: TAAs of the MAGE family represent targets of active specific immunotherapy. Limited-size studies indicate that they are expressed in normal testis and tumors of different histologies.
Background: Interphase fluorescence in situ hybridization (FISH) is a powerful tool for detecting chromosome and locus-specific changes in tumor cells. We developed a FISH-based assay to detect genetic changes in bronchial washing specimens of lung carcinoma patients.
Methods: The assay uses a mixture of fluorescently labeled probes to the centromeric region of chromosome 1 and to the 5p15, 8q24 (site of the c-myc gene), and 7p12 (site of the EGFR gene) loci to assess cells in bronchial washing specimens for chromosomal abnormalities indicative of lung carcinoma.
