Small-Cell Lung Cancer Cavities: Primary or Secondary?

Cureus 2021 Mar 4;13(3):e13691. Epub 2021 Mar 4.

Division of Hematology/Oncology, University of California, Irvine School of Medicine, Irvine, USA.

Although non-small-cell lung cancer occasionally presents as cavitary lesions, it is rare for small-cell lung cancer (SCLC) to present or progress in such a manner. If a cavitary lesion is seen in the setting of small-cell lung carcinoma, infectious etiologies must be excluded first. We present the case of a 43-year-old man with refractory SCLC that progressed despite two lines of therapy, and who was ultimately found to have recurrent adenopathy and numerous widespread cavitary lung nodules.

[Micrographic surgery and its variants].

Rev Med Suisse 2021 Mar;17(732):630-634

Unité de dermatochirurgie, Service de dermatologie et vénéréologie, Département des spécialités de médecine, HUG, 1211 Genève 14.

Cutaneous tumours can be ill-delineated and subclinical tumour can be missed when using the usual methods of pathology processing because only less than 1 % of the margin is examined. Micrographic surgery was developed to allow for examination of 100 % of the margin. It reduces the recurrence rate and spares healthy tissue thus reducing lesion size and facilitating reconstruction.

Automated Detection of Aggressive and Indolent Prostate Cancer on Magnetic Resonance Imaging.

Med Phys 2021 Mar 24. Epub 2021 Mar 24.

Department of Radiology, Stanford University School of Medicine, Stanford, CA, 94305.

Purpose: While multi-parametric Magnetic Resonance Imaging (MRI) shows great promise in assisting with prostate cancer diagnosis and localization, subtle differences in appearance between cancer and normal tissue lead to many false positive and false negative interpretations by radiologists. We sought to automatically detect aggressive cancer (Gleason pattern ≥ 4) and indolent cancer (Gleason pattern 3) on a per-pixel basis on MRI to facilitate the targeting of aggressive cancer during biopsy.

Methods: We created the Stanford Prostate Cancer Network (SPCNet), a convolutional neural network model, trained to distinguish between aggressive cancer, indolent cancer, and normal tissue on MRI. Read More

Steep posterior slope of the medial tibial plateau is associated with ramp lesions of the medial meniscus and a concomitant anterior cruciate ligament injury.

Asia Pac J Sports Med Arthrosc Rehabil Technol 2021 Apr 13;24:23-28. Epub 2021 Feb 13.

Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, 2-5-1 Shikatacho, Kitaku, Okayama, 700-8558, Japan.

Background: Medial meniscus (MM) tears are associated with both acute and chronic anterior cruciate ligament (ACL) insufficiency and can lead to degenerative changes in the knee. ACL reconstruction (ACLR) combined with the meniscal repair was reported to result in decreased anterior knee joint laxity with evidence of improved patient-reported outcomes in the long term. However, a subtle tear of the MM posterior segment, also known as a ramp lesion, is difficult to detect on conventional magnetic resonance imaging (MRI) and is frequently missed in ACL-deficient knees.

Arthroscopic Anterior Cruciate Ligament Injury in Clinical Treatment of Joint Complications and CT Observation.

J Healthc Eng 2021 22;2021:6667046. Epub 2021 Feb 22.

Affiliated Hangzhou First People's Hospital, Zhejiang University School of Medicine, Orthopedics Department, Hangzhou 310006, Zhejiang, China.

Arthroscopy is the gold standard for diagnosing ACL injuries. It is a dual clinical technique for examination and treatment, which can effectively target the injury site for repair and treatment and can also accurately identify the lesion site and determine the degree of ligament injury through visual and three-dimensional observation of ligament injuries that are difficult to detect on imaging. However, this technique is invasive, so the clinic still needs to improve the related auxiliary imaging examination. Read More
