Nodules Less Than 20 mm and Vascular Invasion are Predictors of Survival in Small Hepatocellular Carcinoma

Background: The aims of this study were to analyze the overall survival of patients with cirrhosis and small hepatocellular carcinoma (HCC) and identify independent pretreatment predictors of survival in Brazil. Methods: Between 1998 and 2003, 74 patients with cirrhosis and small HCC were evaluated. Predictors of survival were identified using the Kaplan-Meier survival curves and the Cox model. Results: The overall survival rates were 80%, 41%, and 17% at 12, 36, and 60 months, respectively. The mean length of follow-up after HCC diagnosis was 23 months (median 22 mo, range: I to 86 mo) for the entire group. Univariate analysis showed that model for endstage liver disease (MELD) score (P = 0.016), Child-Pugh classification (P = 0.007), alpha-fetoprotein level (P = 0.006), number of nodules (P = 0.041), tumor diameter (P = 0.009), and vascular invasion (P < 0.0001) were significant predictors Of Survival. Cox regression analysis identified vascular invasion (relative risk = 14.60, confidence interval 95% = 3.3-64.56, P < 0.001) and tumor size > 20 mm (relative risk = 2.14, confidence interval 95% = 1.07-4.2, P = 0.030) as independent predictors of decreased survival. Treatment of HCC was related to increased overall survival. Conclusions: Identification of HCC smaller than 20 mm is associated with longer survival. Presence of vascular invasion, even in small tumors, maybe associated with poor prognosis. Treatment of small tumors Of LIP to 20 mm diameter is related to increased survival.

Influence of Modified Posterior Reconstruction of the Rhabdosphincter on Early Recovery of Continence and Anastomotic Leakage Rates after Robot-Assisted Radical Prostatectomy

Background: Posterior reconstruction (PR) of the rhabdosphincter has been previously described during retropubic radical prostatectomy, and shorter times to return of urinary continence were reported using this technical modification. This technique has also been applied during robot-assisted radical prostatectomy (RARP); however, contradictory results have been reported. Objective: We describe here a modified technique for PR of the rhabdosphincter during RARP and report its impact on early recovery of urinary continence and on cystographic leakage rates. Design, setting, and participants: We analyzed 803 consecutive patients who underwent RARP by a single surgeon over a 12-mo period: 330 without performing PR and 473 with PR. Surgical procedure: The reconstruction was performed using two 6-in 3-0 Poliglecaprone sutures tied together. The free edge of the remaining Denonvillier`s fascia was identified after prostatectomy and approximated to the posterior aspect of the rhabdosphincter and the posterior median raphe using one arm of the continuous suture. The second layer of the reconstruction was then performed with the other arm of the suture, approximating the posterior lip of the bladder neck and vesicoprostatic muscle to the posterior urethral edge. Measurements: Continence rates were assessed with a self-administrated, validated questionnaire (Expanded Prostate Cancer Index Composite) at 1, 4, 12, and 24 wk after catheter removal. Continence was defined as the use of ""no absorbent pads."" Cystogram was performed in all patients on postoperative day 4 or 5 before catheter removal. Results and limitations: There was no significant difference between the groups with respect to patient age, body mass index, prostate-specific antigen levels, prostate weight, American Urological Association symptom score, estimated blood loss, operative time, number of nerve-sparing procedures, and days with catheter. In the PR group, the continence rates at 1, 4, 12, and 24 wk postoperatively were 22.7%, 42.7%, 91.8%, and 96.3%, respectively; in the non-PR group, the continence rates were 28.7%, 51.6%, 91.1%, and 97%, respectively. The modified PR technique resulted in significantly higher continence rates at 1 and 4 wk after catheter removal (p = 0.048 and 0.016, respectively), although the continence rates at 12 and 24 wk were not significantly affected (p = 0.908 and p = 0.741, respectively). The median interval to recovery of continence was also statistically significantly shorter in the PR group (median: 4 wk; 95% confidence interval [CI]: 3.39-4.61) when compared to the non-PR group (median: 6 wk; 95% CI: 5.18-6.82; log-rank test, p = 0.037). Finally, the incidence of cystographic leaks was lower in the PR group (0.4% vs 2.1%; p = 0.036). Although the patients` baseline characteristics were similar between the groups, the patients were not preoperatively randomized and unknown confounding factors may have influenced the results. Conclusions: Our modified PR combines the benefits of early recovery of continence reported with the original PR technique with a reinforced watertight closure of the posterior anastomotic wall. Shorter interval to recovery of continence and lower incidence of cystographic leaks were demonstrated with our PR technique when compared to RARP with no reconstruction.

Lichen planus sialadenitis: a mucosal analog of lichen planopilaris and lichen planoporitis

Lichen planus (LP) is the most prevalent dermatological disorder with oral manifestation. Oral lesions comprise a broad spectrum of clinical presentations. We report the case of a 56-year-old woman who presented erosive LP on the buccal and lower lip mucosae. Besides typical erosions, small white keratotic papules on an erythematosus background on the lower lip mucosa were observed. Biopsy of lower lip lesions showed an unusual histopathological presentation consisting of a lichenoid inflammation targeted to salivary gland ducts. This is probably a salivary gland analog of lichen planopilaris and lichen planoporitis.

MLPA analysis in 30 Sotos syndrome patients revealed one total NSD1 deletion and two partial deletions not previously reported

Sotos syndrome (MIM #117550) is an autosomal dominant condition characterized by pre and postnatal overgrowth, macrocephaly and typical facial gestalt with frontal bossing, hypertelorism, antimongoloid slant of the palpebral fissures, prominent jaw and high and narrow palate. This syndrome is also frequently associated with brain, cardiovascular, and urinary anomalies and is occasionally accompanied by malignant lesions such as Wilms turnout and hepatocarcinoma. The syndrome is known to be caused by mutations or deletions of the NSD1 gene. To detect both 5q35 microdeletions and partial NSD1 gene deletions we screened 30 Brazilian patients with clinical diagnosis of Sotos syndrome by multiplex ligation dependent probe amplification. We identified one patient with a total deletion of NSD1 and neighbouring FGFR4, other with missing NSD1 exons 13-14 and another with a deletion involving FGFR4 and spanning up to NSD1 exon 17. All deletions were de novo. The two NSD1 partial deletions have not been previously reported. The clinical features of the three patients included a typical facial gestalt with frontal bossing, prominent jaw and high anterior hairline; macrocephaly, dolichocephaly, large hands; neonatal hypotonia and jaundice. All presented normal growth at birth but postnatal overgrowth. Two patients with NSD1 and FGFR4 gene deletions presented congenital heart anomalies. (C) 2009 Elsevier Masson SAS.

Twenty seven-year experience with sternal cleft repair

Congenital sternal cleft is a rare disease, and primary repair in the neonatal period is its best management. In 1998 we presented three surgical techniques for sternal cleft correction, but since 1999 we have elected one of them as our procedure of choice. Our latest results are now presented. It is a review of 15 patients operated from October 1979 to December 2007. Surgical repair consisted of 3 sliding chondrotomies, 10 reconstructions basec on a `posterior sternal wall`, 1 reconstruction combined to Ravitch operation for pectus excavatum and 1 associated with total repair of Cantrell`s pentalogy. Data concerning epidemiological features, surgical reconstruction, aesthetic results, postoperative major complications, mortality and hospital stay, were collected from hospital charts. Follow-up ranged from 4 months to 27 years. All patients submitted to surgical, correction had a good aesthetic and functional result. Neither postoperative mortality nor major complication was observed. Two patients had subcutaneous fluid collection that prolonged the drainage duration. The mean hospital stay was 6 days. In conclusion, reconstructing sterna. cleft with a `posterior periosteal flap from sternal bars and chondral graft` is an effective option with good aesthetic and long-term functional results.

Combination micrografting and tattooing in the reconstruction of eyebrows of patients with craniofacial clefts

The absence of an eyebrow, either partial or total, has been observed in patients with craniofacial clefts, such as the Tessier 9 to 13 cleft. Several techniques have been used to improve the appearance of the region, such as island scalp flaps and scalp strip grafting, with limited or marginally satisfactory aesthetic results. The authors report 2 patients with craniofacial clefts in whom a novel technique combining 2 separate surgical approaches, micrografting and tattooing, was used. The use of micrografting with single or double hair units, properly angulated, produces natural-looking and satisfactory results with a minimum of morbidity. Excellent volume and appearance of the eyebrow may be achieved in a single session using this technique. Tattooing performed subsequently over the microimplanted hairs provides the illusion of greater density to the eyebrow, resulting in an appearance closer to normal.

IGFR-I expression and structural analysis of the hard palatine mucosa in an ethanol-drinking rat strain (UChA and UChB)

The study analyzed the effects of chronic alcohol ingestion on the ultrastructure of the lining epithelium of the hard palatine mucosa of rats UChA and UChB (lines with voluntary alcohol consumption) in order to contribute to the understanding of the consequences of alcohol abuse for the morphology of the digestive system. Thirty female adult animals aged 120 days were divided into three experimental groups. (1) Ten UChA rats (genetically low ethanol consumer) with voluntary intake of 10% v/v (5.45 g/kg/day) ethanol solution and water. (2) Ten UChB (genetically high ethanol consumer) rats with voluntary intake of 10% v/v (7.16 g/kg/day) ethanol solution and water. (3) Ten Wistar rats with voluntary ad libitum water intake (control group). Both groups received Nuvital pellets ad libitum. The IGFR-I expression was intense in both experimental groups. The epithelial cells of the alcoholic rats UChA and UChB showed many alterations such as the presence of lipid droplets, altered nuclei, nuclei in corneum layer and disrupted mitochondria. It was concluded that ethanol intake induces ultrastructural lesions in the hard palatine mucosa. (C) 2011 Elsevier Ltd. All rights reserved.

Ophthalmic Considerations in the Management of Tessier Cleft 5/9

Purpose: To describe a patient with Tessier cleft number 5 and 9 and review the literature on the ocular impairment and management of this extremely rare anomaly. Methods: Interventional case report and literature review. Results: The literature review showed that the present patient is the second case with clefts 5/9. The ophthalmic consequences of this rare association are virtually unreported. Our case demonstrates that the presence of cleft number 9 adds a cicatricial component on the upper eyelid that severely impairs the dynamics of this lid. The corneal status of the patient was successfully managed with simultaneous upper eyelid lengthening and facial reconstruction. Conclusion: In order to avoid corneal perforation, simultaneous upper and lower eyelid reconstruction is mandatory in cases of cleft 5/9. The affected patients should be continuously followed in order to prevent amblyopia.

Gastroesophageal Reflux in Severe Cases of Robin Sequence Treated With Nasopharyngeal Intubation

Objective: To study the prevalence of abnormal gastroesophageal reflux in infants with Robin sequence who had severe respiratory obstruction treated with nasopharyngeal intubation and to evaluate the efficacy of nonsurgical treatment. Design: Longitudinal prospective study. Setting: Hospital de Reabilitacao de Anomalias Craniofaciais, University of Sao Paulo, Brazil. Patients: Twenty infants with severe isolated Robin sequence treated with nasopharyngeal intubation. Interventions: We performed 24-hour esophageal pH monitoring on each child at 2, 4, and 6 months of age. Respiratory and feeding status were evaluated. We considered abnormal gastroesophageal reflux as reflux index values above the 95th percentile of the Vandenplas reference for normal children. Results: The prevalence of reflux index above the 95th percentile at the first exam was 6/20, a value significantly higher than the reference (5/103, p < .01). At the second and third exams, reflux index values were decreased. Ninety percent of the infants showed improvement of respiratory difficulty and developed oral feeding capacity. Conclusions: The prevalence of abnormal gastroesophageal reflux is higher in infants with severe cases of Robin sequence than in normal infants. Nonsurgical procedures improved respiratory and feeding difficulties of most of these infants.

Follicular lymphoma in the palate with clinical appearance similar to salivary gland tumors

Intraoral presentation of follicular lymphoma is rare, and only three cases in the palate have been reported to date. The present case report describes an uncommon case of follicular lymphoma affecting the palate. The clinical aspect was similar to salivary gland neoplasm, and an incisional biopsy was important to establish the correct diagnosis and consequently to plan the treatment. Also discussed is the differential diagnosis among follicular lymphoma, mucosa-associated lymphoid tissue lymphoma, and follicular lymphoid hyperplasia with regard to the histopathologic and immunohistochemical features.

WNT-5A, but not matrix metalloproteinase 3 or beta-catenin protein, expression is related to early stages of lip carcinogenesis

Background: Oncogenic Wnt/beta-catenin signaling occurs in numerous types of cancers, but little is known about the role of the Wnt protein family member, WNT-5A, in lip carcinogenesis. The aim of this study was to investigate WNT-5A, beta-catenin, and matrix metalloproteinase (MMP)-3 protein expression in actinic cheilitis (AC), and lip squamous cell carcinoma (LSCC). Methods: Twenty-one cases of AC, and fifty-one cases of LSCC were analyzed, with normal lip mucosa used as a control. Qualitative and semi-quantitative analyses of WNT-5A, beta-catenin, and MMP-3 immunostaining pattern and cellular distribution were performed. Results: WNT-5A was observed in more than 50% of the cells, scattered in all layers of AC, in contrast to the absence of immunostaining in normal lip mucosa. AC presented a higher level of WNT-5A expression than LSCC (P = 0.0289, Fisher test), while MMP-3 immunoexpression was statistically more significant in LSCC than in AC (P = 0.0285, Fisher test). Immunolabeling of beta-catenin protein was differentially distributed between samples; the majority of AC cases (61.90%) demonstrated a membranous-cytoplasmic pattern, while a considerable number of LSCC cases (29.41%) revealed a cytoplasmic pattern, instead of the usual membranous pattern. Conclusions: The present results suggest that WNT-5A may be an important marker during initial events of AC malignant transformation, in which non-canonical and canonical Wnt/beta-catenin signaling pathways could be involved. Additionally, WNT-5A might recruit other events in LSCC, such as MMP-3 protein synthesis, as its presence is increased in established malignant processes without beta-catenin dependency.

Long-term effects of pharyngeal flaps on the upper airways of subjects with velopharyngeal insufficiency

Objectives: To investigate the long-term effects of pharyngeal flap surgery (PFS) on nasal and nasopharyngeal dimensions of patients with velopharyngeal insufficiency (VPI) and to correlate the findings with the onset of respiratory complaints after surgery. Design/Participants: Prospective study in 58 nonsyndromic patients with repaired cleft palate and VPI, evaluated 2 days before and 5 months (POST1) and 1 year (POST2) after PFS, on average. Patients were divided into two groups: one consisting of patients with postoperative respiratory complaints (RC group) and the other without complaints (NRC group). Interventions: Superiorly based PFS. Main Outcome Measures: Respiratory complaints (self reports of mouth breathing, snoring, and other sleep obstructive events) assessed at POST1 and POST2, and minimum nasal (NCSA) and nasopharyngeal (NPA) cross-sectional areas assessed by rhinomanometry at POST2. Results: Respiratory complaints were reported by 55% and 36% of the patients evaluated at POST1 and POST2, respectively. Posterior rhinomanometry showed a significant postoperative reduction of mean NCSA in the RC and NRC groups (p < .05), to subnormal levels in some of them. The decrease was more pronounced in the RC group. No significant changes in NCSA were observed by anterior rhinomanometry. Similar results were obtained when NPA was assessed by modified anterior rhinomanometry. Conclusion: In the long-term, PFS yielded a significant reduction in upper airways dimensions beyond what should be expected and associated with persistent respiratory complaints in some cases.

Schwannoma in the lower lip mucosa: Unexpected diagnosis

Schwannoma is a benign tumor arising from nerve-sheath Schwann cells. When it affects the mouth, the lips are rarely involved. A MEDLINE search in the English literature from 1969 to 2009 revealed only 17 documented cases of schwannomas of the lip. This report describes the unusual case of a 52-year-old man who developed a schwannoma of the lower lip. Histopathologic examination and immunohistochemical staining studies were performed. Although rare, schwannoma should be considered in the differential diagnosis of any nodule or mass in the oral mucosa. (Quintessence Int 2010; 41: 769-771)
