Comparison of three modalities of teleophthalmology delivery in regional Western Australia during the COVID-19 lock-down.

Clinical Relevance: In conjunction with local optometry services, telehealth may be used in to provide specialist care for patients living in rural areas underserved by ophthalmology.

Background: To combat travel restrictions for specialist outreach to regional areas during the 2020 COVID-19 lockdown, Lions Outback Vision introduced three different modalities of teleophthalmology consultations; home-based telephone, hospital-based video, and optometry-based video. This study evaluated the utility of these in providing specialist care to rural patients during the pandemic.

Phosphido-borane-supported stannates.

The reactions between SnCl and three equivalents of the alkali metal phosphido-borane complexes [RP(BH)]M yield the corresponding tris(phosphido-borane)stannate complexes [LM{RP(BH)}Sn] [R = iPr, LM = (THF)Li (2Li), (EtO)Na (2Na), (EtO)K (2K); R = Ph, LM = (THF)Li (3Li), (THF)(EtO)Na (3Na), (THF)(EtO)K (3K); R = iPrPh, LM = (THF)Li (4Li)]. In each case X-ray crystallography reveals an anion consisting of a trigonal pyramidal tin centre coordinated by the P atoms of the phosphido-borane ligands. These tris(phosphido-borane)stannate anions coordinate to the alkali metal cations their BH hydrogen atoms in a variety of modes to give monomers, dimers, and polymers, depending on the alkali metal and the substituents at the phosphorus centres.

The Incidence of Confounding Factors in Patients With Diabetes Mellitus Hospitalized for Diabetic Foot Ulcers.

Introduction: Uncontrolled deformity, deep infection, and/or ischemia-hypoxia are highly associated with healing challenges of diabetic foot ulcers (DFUs). This paper reports the occurrences of these factors that the authors label the "Troublesome Triad" (TT) in a prospective series of 62 patients with diabetes mellitus (DM), who were hospitalized because of their DFUs.

Materials And Methods: With Institutional Review Board approval, the authors gathered data in a prospective series of patients hospitalized because of lower extremity wounds.

Atypical presentation of verrucous carcinoma: a case study and review of the literature.

Unlabelled: Verrucous carcinoma is a slow-growing lesion that is most often found on the weight-bearing surface of the foot and should be considered in the differential diagnosis for chronic nonhealing wounds in the diabetic neuropathic population. Accurate diagnosis may be difficult initially and often requires repeat histopathologic evaluation by an experienced pathologist. Verrucous carcinoma can invade deeper tissues; however, extension to bone is a rare occurrence.
