RESUMO

We assessed the postoperative nasal form and symmetry after presurgical use of a Hotz plate (HP) in patients with unilateral complete cleft lip and palate (UCLP). The subjects were 28 infants with UCLP who underwent cheiloplasty. Of these subjects, 14 underwent presurgical orthopedic treatment using the HP (HP group) and 14 underwent the same treatment without the HP (non-HP group). Photographic records were obtained 1 and 6 months after cheiloplasty, and the results of anthropometric analysis were compared between the 2 groups. The nasal inclination and the ratio of the width of the nasal base to the total width of the nose were significantly improved in the HP group compared with the non-HP group at both postoperative time points. Thus, presurgical use of the HP significantly improved the nasal asymmetry and deformity in UCLP patients after primary cheiloplasty and nasal repair.

RESUMO

We evaluated the effects of presurgical nasoalveolar molding (NAM) with an orthopedic appliance and compared them with a passive orthopedic method (Hotz plate, HP), focusing on the naris morphology and width of the alveolar and palate cleft gap. The subjects were 28 unilateral complete cleft lip and palate patients treated with primary cheiloplasty at Tsukuba University Hospital from 2004 to 2011. Thirteen patients were treated preoperatively with NAM (NAM group), and 15 with HP (HP group). The surgical outcome was assessed according to left-right naris symmetry, as measured by the area ratio, perimeter ratio, aspect a/u ratio (aspect ratio of the affected side/aspect ratio of the unaffected side), and Hausdorff distance. In addition, the alveolar and palate cleft width was measured at the times of orthopedic plate setting and primary cheiloplasty. The aspect ratio was significantly smaller in the NAM group than in the HP group before the operation. In both groups, the aspect ratio, perimeter ratio, and Hausdorff distance were significantly smaller after the operation than before. The width of the alveolar and palate cleft gap was significantly narrowed in the NAM group, and the cleft gap at the initiation of NAM correlated significantly with the Hausdorff distance after cheiloplasty. We found that NAM improved the form of the naris after primary cheiloplasty and decreased the palate cleft gap more effectively than HP and that the width of the palate cleft gap was correlated with the surgical outcome of the naris.

RESUMO

OBJECTIVE: To evaluate surgery results, we established a novel method to digitize nasal morphology with the use of Hausdorff distance and analyzed nose morphology after cheiloplasty. STUDY DESIGN: We evaluated the naris after primary cheiloplasty of 30 unilateral cleft lip and palate patients. Similarity between left and right sides was assessed by visual evaluation, area ratio, perimeter ratio, aspect a/u ratio, and Hausdorff distance. The postoperative naris morphology was also compared between 15 patients treated with a Hotz plate before surgery and 15 not treated. RESULTS: Significant correlation with visual evaluation was found for Hausdorff distance. For the groups with and without Hotz plate treatment, the visual evaluation was higher and Hausdorff distance significantly lower in the treated group. CONCLUSIONS: The morphologic measurement obtained using the Hausdorff distance was the closest to visual evaluation, and assessment using Hausdorff distance suggested that using a Hotz plate helps retain the symmetry of the nares after cheiloplasty.

RESUMO

Angiosarcoma is an uncommon malignancy, which spread out from the endothelial cells of vessels. Scalp angiosarcoma with cervical lymph node metastasis is particularly rare. This article describes a rare case of angiosarcoma of the scalp, presenting as neck inflammation. Imaging procedures such as computed tomography (CT), magnetic resonance image (MRI) and ultrasonography (US) were not sufficient to diagnose this case. A needle biopsy provided an effective and accurate diagnosis of cervical lymph node metastasis. Additional observation and physical examination was required to diagnose the origin of the primary cancerous lesion. Once the angiosarcoma diagnosis was confirmed histologically, sequential weekly and monthly docetaxel (DTX) treatment was effective in preventing reoccurrence. Nonetheless, the optimization of angiosarcoma treatment remains a future goal. Although patients generally describe pain and swelling at the primary lesion site, this patient complained only of painful neck inflammation, without any indication of pain or swelling of the scalp. A revised diagnostic protocol should note that cervical lymph node metastasis of unknown primary origin may result from angiosarcoma of the scalp.

RESUMO

We compared conventional ultrasound (US) B-mode, color Doppler and elastographic assessment of lymph node (LN) stiffness against pathological findings from surgical samples, to determine the most useful factors for identifying LN metastases. Seventy-one LNs in 19 patients with oral squamous cell carcinoma (OSCC) were examined. Using our new system, elastography images were scored from 1-5. The score 1-4 were correlated with the blue area of each LN, which indicated increased stiffness: (1) none; (2) < 50%; (3) 50%; or (4) > 50%. A score 5 indicated central necrosis and did not correlate with the blue area. We found significant differences in minimal diameter, shape index, margin, internal structure, hilus presence or absence, elastography score and percentage of blue area between metastatic and nonmetastatic LNs. Stepwise regression analysis identified elastography score 3-5 as an independent significant LN metastatic factor, suggesting that our scoring system may be useful for accurately diagnosing metastatic LNs.

RESUMO

We investigated the production of interleukin-1 (IL-1) activity by Kupffer cells (KC) from mice treated with a neutral mannan fraction (WNM) or an acidic mannan fraction (WAM025) from baker's yeast (Saccharomyces cerevisiae) in vivo and in vitro. The mice administered WAM025 showed an increase in the number of KC and the IL-1 production compared with mice administered WNM. In an in vitro stimulation assay using KC from a normal mouse, it was also found that WAM025 displayed an increase in IL-1 production. Diisopropyl fluorophosphate completely inhibited the production of IL-1 by KC from the mice administered WAM025.

RESUMO

With most immunological reactions, tissue fibrosis, collagen overproduction caused by immune cytokines, is inevitably associated. Among the various immune cytokines, heat shock protein 47 (HSP47) is a procollagen-specific molecular chaperon and is essential for secretion of procollagen from cells. Induction of HSP47 by TGF-beta has been previously reported in rat skeletal myoblasts and mouse osteoblasts, but not in human diploid fibroblasts. As for IL-1beta, its effect on HSP47 has not been elucidated. In the present study, using human embryonic lung fibroblast cells, we first disclosed that both TGF-beta and IL-1beta induced HSP47 synthesis. We then revealed that the binding of the heat shock element (HSE) by heat shock transcription factor 1 (HSF1) was enhanced by both cytokines. We further demonstrated that trimer formation of HSF1, which is essential for its binding to HSE, was induced by these cytokines. The enhancement of HSP47 synthesis and their trimer formation of HSF1 were augmented by using a combination of both cytokines. Collectively, TGF- beta and IL-1beta were found to induce trimer formation of HSF1 which in turn bound to HSE of HSP47, resulting in the enhancement of HSP47 expression. Thus, HSP47 could well be a good candidate for molecular targeting in controlling tissue fibrosis, given that both principal fibrinogenetic cytokines (TGF-beta, IL-1beta) are commonly involved in its induction through HSF1 trimerization.
