Calciphylaxis: a rare but potentially fatal event of chronic kidney disease. Case report

Calciphylaxis or calcific uremic arteriolopathy is a rare cutaneous-systemic disease occurring in patients with advanced chronic kidney disease. The classical clinical picture is that of a necrotic and progressive skin ulcer of reticular pattern, mostly in the lower legs and susceptible to local infection. It is a product of mural calcification and occlusion of cutaneous and sub-cutaneous arteries and arterioles. The authors report the case of a 73-year-old male patient in his late stage of renal disease presenting severe necrotic cutaneous ulcers on lower legs followed by local and systemic infection and death due to sepse after parathyroidectomy.

Gastroprotective effects (in rodents) of a flavonoid rich fraction obtained from Syngonanthus macrolepsis

Objectives: Syngonanthus macrolepis, popularly known in Brazil as sempre-vivas', is a plant from the family Eriocaulaceae, it is found in the states of Minas Gerais and Bahia. The species contains a variety of constituents, including flavonoids with gastroprotective effect. In this work, a flavonoid-rich fraction (Sm-FRF) obtained from scapes of S.macrolepis was investigated for preventing gastric ulceration in mice and rats.MethodsThe activity was evaluated in models of induced gastric ulcer (absolute ethanol, stress, non-steroidal anti-inflammatory drugs and pylorus ligation). The cytoprotective mechanisms of the Sm-FRF in relation to sulfhydryl (SH) groups, nitric oxide (NO) and antioxidant enzymes were also evaluated.Key findingsThe Sm-FRF (100mg/kg, p.o.) significantly reduced gastric injury in all models, and did not alter gastric juice parameters after pylorus ligation.ConclusionsThe results indicate significant gastroprotective activity for the Sm-FRF, which probably involves the participation of both SH groups and the antioxidant system. Both are integral parts of the gastrointestinal mucosa's cytoprotective mechanisms against aggressive factors.

Diabetic peripheral neuropathy in ankles and feet: muscle strength and plantar pressure

This study aims to evaluate and correlate the vascular, sensory and motor components related to the plantar surface in individuals with diabetic peripheral neuropathy. 68 patients were categorized into two groups: 28 in the neuropathic group and 40 in the control group. In each patient, we assessed: circulation and peripheral perfusion of the lower limbs; somatosensory sensitivity; ankle muscle strength; and pressure on the plantar surface in static, dynamic and gait states. We used the Mann-Whitney test and analysis of variance (ANOVA and MANOVA) for comparison between groups, and performed Pearson and Spearman linear correlations amongst the variables (P < 0.05). The somatosensory sensitivity, peripheral circulation and ankle muscle strength were reduced in the neuropathic group. In full peak plantar pressures, no differences were seen between groups, but differences did appear when the foot surface was divided into regions (forefoot, midfoot and hindfoot). In the static condition, the plantar surface area was greater in the neuropathic group. In the dynamic state, peak pressures in the neuropathic group, were higher in the forefoot and lower in the hindfoot, as well as lower in the hindfoot during gait. There were positive or negative correlations between the sensitivity deficit, dorsal ankle flexor strength, plantar surface area, and peak pressure by plantar region. The sensitivity deficit contributed to the increased plantar surface area.
