RESUMO

BACKGROUND: This study compares patient-reported functional and aesthetic outcomes of split-thickness skin graft (STSG) versus hatchet flap closure of radial forearm free flap (RFFF) donor site. METHODS: Patients with RFFF (2015-2020) were retrospectively identified. Those willing to participate in patient-reported outcomes (PRO) filled out Patient-Observer Scar Assessment Scale (POSAS) and Michigan Hand Outcome Questionnaire (MHOQ). RESULTS: 198 patients met our inclusion criteria and 81 participated in PRO. There was a higher rate of tendon exposure in STSG versus hatchet flap (11 vs. 1, p = 0.0019), but a lower rate of skin necrosis (5 vs. 16, p = 0.0190) and epidermolysis (1 vs. 12, p = 0.0028). Scar quality in STSG was superior to hatchet flap in all domains of POSAS. MHOQ scores were similar between both groups with no statistical difference in overall scores (p = 0.2165). CONCLUSIONS: STSG appeared to have less compromise in activities of daily living, better satisfaction and improved scar quality than hatchet flap, but a higher rate of tendon exposure.

RESUMO

Late-onset nasolacrimal duct obstruction (NLDO) as a result of inflammatory processes causing dacryo-stenosis is a common entity affecting mostly women. While a few mechanisms have been suggested as contributors to the expression of NLDO, the trigger for the inflammation remains mostly unknown. Familial predilection for this condition has not been previously reported. We present two families with multiple individuals affected with congenital or late-onset NLDO, describe the signs and symptoms of the affected individuals, and explore their medical history for any contributing factors. Family A, spanning four generations, included 7 female patients affected by late-onset NLDO. Family B, spanning two generations, included 8 individuals affected by either congenital or late-onset NLDO. This case series suggests a familial predisposition to NLDO, apparently with an autosomal dominant inheritance pattern. Further studies are needed to elucidate the molecular basis of this genetic predisposition.

RESUMO

PURPOSE: To investigate the effect of Bell's palsy (BP) presenting as polycranial neuropathy (PCN) compared with BP caused by isolated facial nerve (CNVII). METHODS: We carried out a retrospective cohort study of the medical records of all consecutive patients who were diagnosed with BP at a single tertiary referral center between 2010 and 2017. Included were patients 18 years or older who were clinically diagnosed with BP and completed 7 days of systemic steroidal treatment and at least 6 months of follow-up. The patients were divided into two groups according to whether the BP derived from a monocranial neuropathy or a PCN. Demographics and BP severity and outcome were compared between these groups. A systematic literature review using Medline via "PubMed," "Embase," and "Web of Science" was conducted. RESULTS: In total, 321 patients with BP were enrolled. The median (interquartile range) age at presentation was 44 (33-60) years. Sex distribution showed male predominance of 57.6% (n = 185) versus 42.4% (n = 136), and 21.2% (n = 68) had PCN. The most concomitantly affected cranial nerve (CN) was the trigeminal (CNV; n = 32, 47%), followed by the glossopharyngeal nerve (CNIX; n = 14, 21%) and the audiovestibular nerve (CNVIII; n = 10, 15%). Age, House-Brackmann score on presentation, and diabetes mellitus (DM) were independent predictors for PCN etiology ( p = 0.001, p = 0.034, and p < 0.001, respectively). Each increase in 1 year of age was associated with additional odds ratio (95% confidence interval) of 0.97 (0.95-0.99) for PCN. The odds ratio (95% confidence interval) associated with DM was 8.19 (4.02-16.70). Our systematic literature review identified 1,440 patients with the PCN type of BP. The most commonly affected CN was the trigeminus (25-48%), followed by the glossopharyngeal and audiovestibular nerves (2-19% and 0-43%, respectively). CONCLUSION: The severity of facial weakness on initial presentation among PCN patients was significantly higher compared with the monocranial neuropathy-type BP patients. The authors believe that the significant association and prevalence rate ratio between DM and PCN warrant that a patient presenting with PCN undergo screening for DM.

RESUMO

AXL overexpression is a common resistance mechanism to anti-cancer therapies, including the resistance to BYL719 (Alpelisib) - the p110α isoform specific inhibitor of phosphoinositide 3-kinase (PI3K) - in esophagus and head and neck squamous cell carcinoma (ESCC, HNSCC respectively). However, the mechanisms underlying AXL overexpression in resistance to BYL719 remain elusive. Here we demonstrated that the AP-1 transcription factors, c-JUN and c-FOS, regulate AXL overexpression in HNSCC and ESCC. The expression of AXL was correlated with that of c-JUN both in HNSCC patients and in HNSCC and ESCC cell lines. Silencing of c-JUN and c-FOS expression in tumor cells downregulated AXL expression and enhanced the sensitivity of human papilloma virus positive (HPVPos) and negative (HPVNeg) tumor cells to BYL719 in vitro. Blocking of the c-JUN N-terminal kinase (JNK) using SP600125 in combination with BYL719 showed a synergistic anti-proliferative effect in vitro, which was accompanied by AXL downregulation and potent inhibition of the mTOR pathway. In vivo, the BYL719-SP600125 drug combination led to the arrest of tumor growth in cell line-derived and patient-derived xenograft models, and in syngeneic head and neck murine cancer models. Collectively, our data suggests that JNK inhibition in combination with anti-PI3K therapy is a new therapeutic strategy that should be tested in HPVPos and HPVNeg HNSCC and ESCC patients.

RESUMO

OBJECTIVES: To evaluate the epidemiology, microbiology, Streptococcus pneumoniae serotypes distribution and serious bacterial infections (SBIs) occurrence in infants <2 months of age with tympanocentesis-documented acute otitis media (AOM), before and after the introduction of pneumococcal conjugate vaccines (PCVs). METHODS: The medical records of all hospitalized infants with AOM who underwent tympanocentesis during 2005-2014 were reviewed. RESULTS: Of the 303 infants with AOM who were diagnosed by an ENT specialist, 182 underwent tympanocentesis, 92 during 2005-2009 (prevaccine period) and 90 during 2010-2014 (postvaccine period). Streptococcus pneumoniae and nontypeable Hemophilus influenzae were isolated in 46/92 (50%) and 37/92 (40.2%) patients during 2005-2009 and decreased to 27/90 (30%) and 21/90 (23.3%). Respectively, during 2010-2014 (P = 0.006 and P = 0.001). The proportion of culture-negative patients increased from 18/92 (19.6%) during 2005-2009 to 32/90 (35.6%) during 2010-2014 (P = 0.02). There were only 6 (3.3%) patients <2 weeks of age. The most common S. pneumoniae vaccine serotypes isolated during 2005-2009 were 5, 3, 1, 19F and 14 (15.2%, 13.0%, 10.9%, 6.5%, and 4.3%, respectively) and 3, 5, 1, 14 and 19A (22.2%, 11.1%, 7.4%, 7.4%, and 7.4%, respectively) during 2010-2014. The proportion of culture-positive patients decreased during 2013-2014 compared with 2011-2012 (7/18, 38.9% vs. 40/54, 74.1%, P = 0.007). Serotypes 1 and 5 were not isolated during 2013-2014 and serotype 19A was not isolated during 2011-2014. . SBIs were recorded in 23/182 (12.64%) patients and urinary tract infections represented 19/23 (82.61%) of them (Escherichia coli isolated in 12, 63.2%). CONCLUSIONS: The overall number of AOM cases needing tympanocentesis seen at the PER and the proportion of S. pneumoniae and nontypeable H. influenzae-AOM decreased while the proportion of culture-negative AOM increased following the introduction of PCVs. SBIs associated with AOM were frequent and were represented mostly by urinary tract infections caused by pathogens unrelated to the etiologic agents of AOM.
