REDESCRIPTION OF HASSALSTRONGYLUS ADUNCUS CHANDLER, 1932 (NEMATODA: HELIGMONELLIDAE), WITH THE DESCRIPTION OF A NEW SPECIES OF THE GENUS AND THEIR PHYLOGENETIC POSITION WITH OTHER HELIGMOSOMOIDEA TRAVASSOS, 1914.

Hassalstrongylus Durette-Desset, 1971 (Nematoda: Heligmonellidae), includes 19 species that are distributed from the southwestern United States to central-western Argentina. Hassalstrongylus aduncus is a parasitic nematode of rodents from the subfamilies Arvicolinae, Murinae, and Sigmodontinae, and has been recorded from southern Virginia and Oklahoma to Costa Rica. This species was described by Chandler in 1932; the morphology of the synlophe was not included.

A NEW SPECIES OF CHIGGER MITE AND THE RECORD OF A GASTROINTESTINAL NEMATODE IN SCELOPORUS CAUTUS (SQUAMATA: PHRYNOSOMATIDAE) FROM THE CHIHUAHUAN DESERT PROVINCE IN COAHUILA, MEXICO.

The chigger species Acomatacarus coahuilensis n. sp. (Acariformes: Trombidiformes: Leeuwenhoekiidae) inhabiting the neck scales of the wary spiny lizard Sceloporus cautus Smith, 1938 (Squamata: Iguania: Phrynosomatidae), from Chihuahuan Desert Province, Coahuila, Mexico, is described herein.

Distal Triceps Tendon Tears: Magnetic Resonance Imaging Patterns Using a Systematic Classification.

Objective: This study aimed to evaluate distal triceps tendon tear patterns using a systematic classification based on the tendon's layered structure.

Methods: We retrospectively identified Magnetic resonance imaging (MRI) examinations with triceps tendon tears that underwent reconstructive surgery. Magnetic resonance images were reviewed independently by 2 musculoskeletal radiologists to determine tendon layer involvement and ancillary findings, including tear size, involvement of triceps lateral expansion, and presence of olecranon bursal fluid.

Kinematic MRI of ischiofemoral impingement.

Objective: To examine the effect of external hip rotation on ischiofemoral (IF) and quadratus femoris (QF) spaces using real-time kinematic MRI, with the hypothesis that hips with IF and QF space narrowing have distinct motion patterns compared with control hips.

Materials And Methods: This prospective study was IRB-approved and complied with HIPAA guidelines. We recruited women (≥ 18 years) with and without ischiofemoral impingement to undergo kinematic MRI of the hips.

Review of Imaging Findings in Urinary Tract Infections.

Acute urinary tract infection diagnosis is primarily performed on clinical grounds. Diagnostic imaging is, however, often necessary as part of the workup for poor response to treatment, to evaluate causative or contributory factors, complicated infections and chronic presentations. Appropriate knowledge of the most relevant radiological findings in urinary tract infections provides pertinent differential diagnosis and guides clinical management, including emergent and aggressive interventions.
