Trichophyton is a species of fungus that commonly infects hedgehogs. As the popularity of keeping hedgehogs as pets increases, there have been reports of Trichophyton species infection in humans. Diagnosis and appropriate treatment of Trichophyton infection can be delayed owing to physicians' low index of suspicion and unfamiliarity with the physical manifestations. We describe a case of a 27-year-old healthy man who developed tinea manuum after handling a pet hedgehog. Presenting symptoms included a worsening bullous eruption and severe pain. Both fungal and histopathological study confirmed Trichophyton infection. He was treated with oral and topical antifungal medication. All symptoms resolved 2 weeks after initiation of treatment.
  Shoulder internal rotation contractures (IRC) are common sequela of brachial plexus birth injuries (BPBI). Botulinum toxin A (BTX-A) injection into targeted muscles has been described to facilitate functional improvement at the shoulder joint and prevent glenohumeral dysplasia. The purpose of this study was to assess the outcomes of BTX-A injections on shoulder IRC in children with BPBI.
 
  We conducted a retrospective analysis of 47 children with shoulder IRC due to BPBI, who were treated with BTX-A. Shoulder passive external rotation in adduction and Active Movement Scale external rotation scores were recorded before and after BTX-A injection.  https://www.selleckchem.com/products/lenalidomide-s1029.html  We also recorded the number of children who underwent secondary surgical balancing procedures to improve shoulder motion after BTX-A injection.
 
  Mean age at the time of injection was 12 months (range, 5-23 months). Subjects demonstrated a significant increase in passive external rotation of 46° (range, 10° to 90) at 4 months; an average improvement of 18° (range, -30° to 80°) persisted at 11 months after injection. A total of 28 patients (60%) underwent subsequent external rotation tendon transfer. At 5-year follow-up, 7 patients (15%) had adequate functional shoulder range of motion and did not undergo external rotation tendon transfer.
 
  Botulinum toxin A injections result in improvement in IRC due to BPBI, which is sustained beyond the expected half-life of 3 months. As many as 15% of patients who have this treatment avoid external rotation tendon transfer.

 Diagnostic IV.Periprosthetic joint infection (PJI) is a potentially devastating complication after total elbow arthroplasty (TEA) that can lead to significant morbidity for the patient as well as increased health care-related costs. Despite the potential morbidity associated with TEA PJI, evidence is limited regarding an optimal treatment algorithm. Initial management typically consists of either irrigation and debridement or 2-stage revision. A stable implant, a functioning triceps, and an intact soft tissue envelope are necessary to perform irrigation and debridement. Irrigation and debridement is associated with a relatively high risk of infection recurrence especially in chronic infections. Two-stage revision offers a lower recurrence risk, although there is a 25% chance of not completing the second stage. Resection arthroplasty, arthrodesis, and amputation are salvage options, whereas medical treatment, in the form of antibiotics alone, is reserved for poor surgical candidates. Further multicenter prospective study and retrospective review of registry data focusing on different treatment algorithms, prevention strategies, and functional outcomes would be helpful to elucidate the ideal management of elbow PJI.The ecological quality status of the NE region of the Guanabara Bay (SE Brazil), one of the most important Brazilian embayments, is evaluated. For this purpose, sediment samples from in the inner of the Guanabara Bay (GB) were collected and analyzed (grain-size, mineralogy, geochemistry and living foraminifera). In this study, it is hypothesized that the potentially toxic elements (PTEs) concentrations, in solution and associated with organic matter (OMPTEs, potential nutrient source), may represent two potential pathways to impact benthic foraminifers. A multiproxy approach applied to complex statistical analyses and ecological indexes shows that the study area is, in general, eutrophic (with high organic matter and low oxygen content), polluted by PTEs and oil. As a consequence, foraminifera are not abundant and their assemblages are poorly diversified and dominated by some stress-tolerant species (i.e., Ammonia tepida, Quinqueloculina seminula, Cribroelphidium excavatum). The results allow us to identify a set of species sensitive to eutrophication and OMPTEs. Factors such as the increase of organic matter contents and OMPTEs and, in particular of Zn, Cd and Pb, the oxygen depletion and the presence of oil, altogether contribute to a marked reduction in the abundance and diversity of foraminifera. Ammonia-Elphidium Index and the Foram Stress Index confirm that the NE zone of GB is, in general, "heavily polluted", with "poor ecological quality status" and experiences suboxic to anoxic conditions. In light of it, special attention from public authorities and policymakers is required in order to take immediate actions to enable its environmental recovery.Siboglinids are a characteristic feature of reducing environments. More than 75% of all siboglinids were found in the Sea of Okhotsk at a depth of less than 400 m, while some species are known to inhabit the abyssal depth in other regions. Among the six species of siboglinids encountered in the Sea of Okhotsk, only two are widespread Siboglinum caulleryi and Oligobrachia dogieli. A significant number of all findings belong to the area where, according to geological data, the methane concentration varies between 0.22 and 4.46*109 nmol/kg. There is a vast territory in the central part of the Sea of Okhotsk that is not inhabited by siboglinids and is characterized by minimum methane concentration values. Thus, data on the Sea of Okhotsk indicate that siboglinids are related to sites of methane seepage.As the role of mercury is poorly known in Southern Ocean biota, the total mercury (T-Hg) concentrations were evaluated in upper/lower beaks, digestive gland, gills and mantle muscle of Adelieledone polymorpha and Pareledone turqueti, two of the most abundant octopod species around South Georgia. Beaks had the lowest T-Hg concentrations (A. polymorpha [T-Hg]Upper = 27.2 ± 12.9 ng∙g-1 and [T-Hg]Lower = 27.5 ± 20.0 ng∙g-1; P. turqueti [T-Hg]Upper = 34.6 ± 13.9 ng∙g-1 and [T-Hg]Lower = 56.8 ± 42.0 ng∙g-1), followed by gills and muscle. The highest values were recorded in the digestive gland (A. polymorpha 251.6 ± 69.7 ng∙g-1; P. turqueti 347.0 ± 177.0 ng∙g-1). Significant relationships were found between the concentrations of T-Hg in the beaks and muscle of A. polymorpha (T-Hg in muscle is 10 times higher than in beaks). This study shows that beaks can be used as proxy for T-Hg in muscle for some octopod species, and a helpful tool for estimating total Hg body burden from beaks.
