Various types of tumors can affect the subungual space, including benign solid tumors (glomus tumor, subungual exostosis, soft-tissue chondroma, keratoacanthoma, hemangioma, lobular capillary hemangioma), benign cystic lesions (epidermal and mucoid cysts), and malignant tumors (squamous cell carcinoma, malignant melanoma). Imaging plays an important role in the detection and differentiation of subungual tumors because of their small size, nonspecific clinical manifestations, and functional significance. Ultrasonography (US)-in particular, high-resolution US with color Doppler studies-provides useful information regarding tumor size, location, shape, and internal characteristics (cystic, solid, or mixed), but it is limited in the further characterization of tissue. Magnetic resonance (MR) imaging has an important role in categorizing tumors according to their anatomic location, pathologic origin, and signal characteristics. There is some overlap between the US and MR imaging features of subungual tumors; however, certain features can allow accurate diagnosis and expedite management when correlated with clinical and pathologic findings.
PurposeThe purpose of our study was to investigate the effects of hippotherapy on gross motor function and functional performance in children with spastic cerebral palsy (CP).Materials and MethodsWe recruited 34 children (M:F=15:19, age: 3-12 years) with spastic CP who underwent hippotherapy for 45 minutes twice a week for 8 weeks. Twenty-one children with spastic CP were recruited for control group. The distribution of gross motor function classification system level and mean age were not significantly different between the two groups. Outcome measures, including the Gross Motor Function Measure (GMFM)-66, GMFM-88 and the Pediatric Evaluation of Disability Inventory: Functional Skills Scale (PEDI-FSS), were assessed before therapy and after the 8-weeks intervention as outcome measures.ResultsThere were no significant differences between intervention and control groups in mean baseline total scores of GMFM-66, GMFM-88 or PEDI-FSS. After the 8-weeks intervention, mean GMFM-66 and GMFM-88 scores were significantly improved in both groups. However, the hippotherapy group had significantly greater improvement in dimension E and GMFM-66 total score than the control group. The total PEDI-FSS score and the sub-scores of its 3 domains were significantly improved in the hippotherapy group, but not in the control group.ConclusionThe results of our study demonstrate the beneficial effects of hippotherapy on gross motor function and functional performance in children with CP compared to control group. The significant improvement in PEDI-FSS scores suggests that hippotherapy may be useful to maximize the functional performance of children with CP.
PurposeThis study aimed to investigate useful parameters for estimating gastrocnemius (GCM) muscle volume (MV) using ultrasonography (US) and anthropometry in children with spastic cerebral palsy (CP).Materials and MethodsEighteen legs from nine children with spastic CP aged 2 to 6 years were investigated in this study. Tibial length (TL) of each leg was measured and muscle thickness (MT) and anatomical cross-sectional area (aCSA) of GCM muscles were assessed using US. The volume of the GCM was measured by magnetic resonance imaging (MRI) scans. The relationship of TL, MT, and aCSA with MV measured by MRI was investigated. Simple and multiple regression analyses were performed to establish muscle volume prediction equations.ResultsResting MT, aCSA, and TL were highly related to MV of both medial and lateral head of GCM determined by MRI. The MV prediction equation based on simple regression analysis resulted in r2 values ranging from 0.591 to 0.832 (p<0.05). The r2 values were higher using aCSA as independent variable than using MT. The MV prediction equation based on multiple regression analysis resulted in r2 values ranging from 0.779 to 0.903 (p<0.05). However, the relatively high standard error of the estimate values ranged from 18.0-33.6% on simple regression and 15.5-25.6% on multiple regression. The contribution of aCSA was higher than that of MT for predicting MV of GCM.ConclusionOur study demonstrated the suitability of US assessment of aCSA and MT combined with TL for estimating MV of GCM in children with spastic CP and showed that aCSA is more useful parameter than MT.
PurposeThis study used ultrasonography (US) to investigate the architectural changes in gastrocnemius muscles (GCM) after botulinum toxin injection (BoNT-A) in children with cerebral palsy (CP).Materials and MethodsThirteen children with CP who received a BoNT-A injection into their GCM to treat equinus were recruited (9 males and 4 females). Architectural changes in both the medial and lateral heads of the GCM from a total of 20 legs were assessed using B-mode, real-time US. Muscle thickness (MT), fascicle length (FL), and fascicle angle (FA) were measured over the middle of the muscle belly in both a resting and neutral ankle position. Measures at 1 and 3 months after the injection were compared with baseline data taken before the injection.ResultsThe mean age of the subjects was 5.8 (±1.6) years. Spasticity was significantly reduced when measured by both the modified Tardieu scale and the modified Ashworth scale at 1 and 3 months after injection (p<0.05). The MT and FA of both the medial and lateral heads of the GCM were significantly reduced for both neutral and resting ankle positions at 1 and 3 months after the injection. The FL of both the medial and lateral heads of the GCM were significantly increased in a resting position (p<0.05), but not in a neutral position.ConclusionOur results demonstrated muscle architectural changes induced by BoNT-A injection. The functional significances of these changes were discussed.
Recently, many chemopreventive agents have been developed from medicinal plants, rich sources of phytochemicals.1) Paeonol is a major phenolic component isolated from the root of Paeonia suffruticosa ANDW, Moutan Cortex, which has been frequently used for treatment of blood stasis and inflammation as a folk remedy.
N-butyl-2-cyanoacrylate could be a useful method for sutureless colonic anastomosis based on the absence of anastomotic leakage, but it may impede healing of the colonic anastomosis. In addition, when used to seal sutured colonic anastomoses, cyanoacrylate may have a negative influence on anastomotic healing. The clinical use of N-butyl-2-cyanoacrylate in colonic anastomosis does not appear to be acceptable and safer anastomotic methods or alternative forms of cyanoacrylate should be developed.
Leuconostoc infections are rare and usually occur in immunocompromised patients. This report describes a case of Leuconostoc lactis bacteremia in a patient with coexisting rheumatoid arthritis and tuberculosis arthritis. A disrupted gastrointestinal barrier due to gastrointestinal amyloidosis in long-standing rheumatoid arthritis and tuberculosis arthritis could be a risk factor for Leuconostoc bacteremia. Despite aggressive antibiotic treatment, the patient progressed to septic shock and multi-organ failure. The fatal course might have been caused by rapid progression of gastrointestinal pathology, which could be a risk factor for Leuconostoc bacteremia.
