Use of anticonvulsants and antidepressants for treatment of complex regional pain syndrome: a literature review

Complex regional pain syndrome (CRPS) is characterized by pain accompanied by symptoms including skin changes, sensory, motor, trophic changes and autonomic dysfunction. Anticonvulsants and antidepressants are commonly prescribed for neuropathic pain conditions; however, evidence is sparse whether these drugs are effective in reducing CRPS-related pain. As such, Pubmed was searched for studies published from January 1990 through March 2020; 13 studies were included in this review. Overall, evidence is considered insufficient for use of gabapentinoids for CRPS-related pain. However, three randomized controlled trials (RCTs) did find gabapentin to result in significant improvement in pain whereas one RCT reported use of amitriptyline to be equally as effective as gabapentin. Multiple case reports discussing the efficacy of pregabalin in pediatric CRPS patients, with relatively short duration of disease and underlying psychiatric illness, have been reported, but these findings need to be validated with RCTs.

Combination of the right heart pathology and varicose disease as a factor of development of trophic changes in the lower extremities: a case report

Varicose disease is the most prevalent vascular disorder affecting lower extremities. Chronic venous insufficiency (CVI) is common in subjects with incompetent superficial and perforator veins. Major attention in pathogenesis of CVI is paid to horizontal venous reflux, while pathological blood flow in the superficial veins may sometimes be regarded as a postural reaction. At the same time cardiac pathology may also attribute to the development of CVI. The article presents a case report describing a female patient with combination of the right heart pathology and varicose disease associated with tricuspid regurgitation leading to constant venous reflux in the lower extremity superficial veins with further development of trophic changes.

Evidence of cultural eutrophication of the Gulf of Gdańsk based on diatom analysis

The objective of this study was to reconstruct the environmental changes in the Gulf of Gdańsk in the last 200 years. Four subbottom sediment cores were analyzed with respect to diatom flora and anthropogenic effects. The so-called “anthropogenic assemblage” – a result of cultural eutrophication – was observed in the surface sediments. Changes in the species composition may have been caused by the increased use of fertilizers, nitrogen loads and increasing organic matter concentration. Three phases (A, B and C) were distinguished based on the floristic spectrum, which clearly indicates trophic changes in the study area.

The Place of Reductive Surgery in the Management of Gestational Ulcerative Gigantomastia: A Case Report at Sourô Sanou Teaching Hospital

Introduction. Gestational gigantomastia is a rare benign disease of unknown cause. We report a case of bilateral gigantomastia in pregnancy in order to locate the place of reductive surgery in its care which is quite controversial. Case. A 25-year-old woman gravida 2 para 1 was referred for an exaggerated bilateral breast enlargement at 32-week gestation. The examination showed bilateral giant breasts with collateral venous circulation and trophic changes marked by the necrosis of the distal third of the mammary skin involving the nipple-areolar complex. She underwent a biopsy of the ulcerative breast tissue, and the histology report did not show a malignant cell. After active foetal lung maturation and induced delivery, a breast reductive surgery with nipple plasty was performed 21 days postpartum. The postoperative course was marked by a period of lymphangitis. The cosmetic and psychological result was satisfactory at 6 months and at 18 months. Conclusion. Gestational gigantomastia is a benign disease that can simulate carcinomatous mastitis. The breast reductive plasty keeps its place in our context.

Pacific walrus diet across 4000 years of changing sea ice conditions

Declining sea ice is expected to change the Arctic's physical and biological systems in ways that are difficult to predict. This study used stable isotope compositions (δ13C and δ15N) of archaeological, historic, and modern Pacific walrus (Odobenus rosmarus divergens) bone collagen to investigate the impacts of changing sea ice conditions on walrus diet during the last ~4000 yr. An index of past sea ice conditions was generated using dinocyst-based reconstructions from three locations in the northeastern Chukchi Sea. Archaeological walrus samples were assigned to intervals of high and low sea ice, and δ13C and δ15N were compared across ice states. Mean δ13C and δ15N values were similar for archaeological walruses from intervals of high and low sea ice; however, variability among walruses was greater during low-ice intervals, possibly indicating decreased availability of preferred prey. Overall, sea ice conditions were not a primary driver of changes in walrus diet. The diet of modern walruses was not consistent with archaeological low sea ice intervals. Rather, the low average trophic position of modern walruses (primarily driven by males), with little variability among individuals, suggests that trophic changes to this Arctic ecosystem are still underway or are unprecedented in the last ~4000 yr.
