Background: Intra-arterial chemotherapy (IAC) for retinoblastoma (Rb) has dramatically altered the natural history of the disease. The spectacular outcomes associated with a high safety profile have pushed the envelope to offer treatment for patients < 10 kg of weight. Objective: We aim to share our findings and experience in a large series of IAC infusions performed in infants < 10 kg. Methods: A retrospective chart review was performed for patients diagnosed with retinoblastoma and managed with IAC as either primary or secondary treatment. Results: There were 207 Rb tumors of 207 eyes in 197 consecutive patients. Of these, patient weight was 10 kg in 69 (35.7%) and >10 kg in 133 (67.5%) patients. Of the 69 patients weighing < 10 kg, 5 patients had bilateral Rb. Thus, a total of 74 eyes of 69 patients weighing < 10 kg were compared to 133 eyes of 133 patients weighing > 10 kg. Comparison ( < 10 kg vs. >10 kg) revealed the total number of IAC cycles was 222 vs. 436. Periprocedural complications occurred in 2 (0.9%) vs. 2 (0.45%) infusions ( p =0.49). Aborted procedure occurred in 12 (5.4%) vs. 7 (1.6%) infusions ( p =0.005). Enucleation following IAC was required in 14 (18.9) vs. 44 (33%) eyes ( p =0.029). On multivariate analysis, weight < 10 kg was not an independent predictor of complications, procedure failure, or eye enucleation. Conclusions: Our results speak for the safety and efficacy of IAC in patients < 10 kg.

Objective Neck dissection (ND) is one of the most commonly performed procedures in head and neck surgery. We sought to compare the morbidity of elective ND (END) versus therapeutic ND (TND). Study Design Retrospective chart review. Setting Academic tertiary care center. Methods Retrospective chart review of 373 NDs performed from January 2015 to December 2018. Patients with radical ND or inadequate chart documentation were excluded. Demographics, clinicopathologic data, complications, and sacrificed structures during ND were retrieved. Statistical analysis was performed with χ2 and analysis of variance for comparison of categorical and continuous variables, respectively, with statistical alpha set a 0.05. Results Patients examined consisted of 224 males (60%) with a mean age of 60 years. TND accounted for 79% (n = 296) as compared with 21% (n = 77) for END. Other than a significantly higher history of radiation (37% vs 7%, P < .001) and endocrine pathology (34% vs 2.6%, P < .001) in the TND group, no significant differences in demographics were found between the therapeutic and elective groups. A significantly higher rate of structure sacrifice and extranodal extension within the TND group was noted to hold in overall and subgroup comparisons. No significant difference in rate of surgical complications was appreciated between groups in overall or subgroup analysis. Conclusion While the significantly higher rate of structure sacrifice among the TND population represents an increased morbidity profile in these patients, no significant difference was found in the rate of surgical complications between groups. The significant difference seen between groups regarding history of radiation and endocrine pathology likely represents selection bias.

The aim of this study was first to describe the natural history of Buerger's disease (BD) and then to discuss a clinical approach to this disease based on multivariate analysis. One hundred eight patients who corresponded with Shionoya's criteria were selected from 2000 to 2007 for this study. Major amputation was considered the ultimate adverse event. Survival analyses were performed by Kaplan–Meier curves. Independent variables including gender, duration of smoking, number of cigarettes smoked per day, minor amputation events and type of treatments, were determined by multivariate Cox regression analysis. The recorded data demonstrated that BD may present in four forms, including relapsing-remitting (75%), secondary progressive (4.6%), primary progressive (14.2%) and benign BD (6.2%). Most of the amputations occurred due to relapses within the six years after diagnosis of BD. In multivariate analysis, duration of smoking of more than 20 years had a significant relationship with further major amputation among patients with BD. Smoking cessation programs with experienced psychotherapists are strongly recommended for those areas in which Buerger's disease is common. Patients who have smoked for more than 20 years should be encouraged to quit smoking, but should also be recommended for more advanced treatment for limb salvage.

AbstractStaphylococcus aureus (SA) is the major colonizer of the lung of cystic fibrosis (CF) patient during childhood and adolescence. As patient aged, the prevalence of SA decreases and Pseudomonas aeruginosa (PA) becomes the major pathogen infecting adult lungs. Nonetheless, SA remains significant and patients harbouring both SA and PA are frequently found in worldwide cohort. Impact of coinfection remains controversial. Furthermore, co-infecting isolates may compete or coexist. The aim of this study was to analyse if co-infection and coexistence of SA and PA could lead to worse clinical outcomes. The clinical and bacteriological data of 212 Lyon CF patients were collected retrospectively, and patients were ranked into three groups, SA only (n=112), PA only (n=48) or SA plus PA (n=52). In addition, SA and PA isolates from co-infecting patients were tested in vitro to define their interaction profile. Sixty five percent (n=34) of SA/PA pairs coexist. Using univariate and multivariate analysis, we confirm that SA patients have a clinical condition less severe than others, and PA induce a poor outcome independently of the presence of SA. FEV1 is lower in patients infected by competition strain pairs than in those infected by coexisting strain pairs compared to SA mono-infection. Coexistence between SA and PA may be an important step in the natural history of lung bacterial colonization within CF patients.

Objective: Trapeziometacarpal (TM) joint arthritis is a common source of hand pain in patients presenting to the hand surgeon’s clinic. Long-term data on the natural history of symptomatic TM arthritis is lacking.Methods: We identified 251 patients with symptomatic TM arthritis and performed a retrospective chart review which identified treatment modalities (including surgery) and long term outcomes which were assessed via a telephone survey.Results: We found that of the 251 patients who presented with symptomatic TM arthritis, the 114 patients who had surgery had less pain and disability in the long term than those patients who were treated conservatively with splinting or injection (average pain score 1.8 vs. 3.8). However, the majority of patients did not ultimately undergo surgery.Conclusions: Although patients fare better from a pain and function standpoint with surgery, surgery is not inevitable.

Background The use of IV insulin infusions in the acute management of hypertriglyceridemia has only been evaluated in small observational studies and case reports. Objective To evaluate the safety and efficacy of IV insulin infusions in the acute management of hypertriglyceridemia. Methods This was a retrospective chart review of adult patients who received an IV insulin infusion for the acute management of hypertriglyceridemia. The primary efficacy and safety outcomes were the number of patients who achieved a triglyceride level <500 mg/dL and experienced hypoglycemia (<70 mg/dL), respectively. A subgroup analysis was performed to compare outcomes between patients with and without diabetes, in addition to the IV insulin infusion rate received. Results In the total population (n = 51), there were no statistically significant differences between the insulin intensity groups in the number of patients who achieved TG levels <500 mg/dL. Compared to patients with a past medical history of diabetes, more patients without a past medical history of diabetes achieved triglyceride levels <500 mg/dL (14% vs 53%, respectively, P < 0.001). The number of hypoglycemic events observed in patients with and without a past medical history of diabetes were 5 (14%) and 4 (27%), respectively ( P = 0.023). Conclusion and Relevance Our findings suggest that patients who present with lower initial TG levels are more likely to achieve TG levels <500 mg/dL. To minimize the risk of hypoglycemia providers should consider prescribing a concomitant dextrose infusion and limiting IV insulin infusion rates ≤ 0.075 units/kg/h.

Background: Prior studies have reported elevated blood pressure, platelet inhibition, and low LDL cholesterol in chronic daily alcohol users (CDA). Each of these has been shown to be associated with intracerebral hemorrhage (ICH) growth. We hypothesized that CDA patients with ICH and low LDL were at higher risk for ICH growth than CDA users with high LDL. Methods: Retrospective chart review was performed on patients who presented to Tulane University from 7/1/08-12/31/10 with a spontaneous ICH. Patients who underwent hematoma evacuation were excluded. Clinical and demographic variables were abstracted. Hemorrhages volumes were calculated based on ABC/2 method. LDL was dichotomized into low (<100mg/dl) and high (≥100mg/dl) values. Comparisons were made using t-tests, Chi-square and non-parametric equivalents where appropriate. ICH growth in 24 hours and CDA use were evaluated using linear regression. Results: Of the 99 patients with spontaneous ICH, 25.3% were CDA users. No significant differences were observed when comparing baseline demographics of CDA users with LDL<100 and CDA users with LDL>=100 ( Table 1). Patients with low LDL had larger baseline ICH volumes (21.4 vs. 7.5, p=.03) and were more likely to experience ICH growth (87.5% vs. 57.1%, p=0.0002). Initial LDL was an independent predictor for 24 hour ICH growth. Every 10 points the initial LDL was below 100 predicted 1 cc of growth. LDL did not predict ICH growth in non-CDA users (p=0.9430). Discussion: Our data suggest that initial LDL level in chronic daily alcohol users can be used to predict ICH growth. The role of LDL in the importance of vessel fragility and clot stabilization needs to be further explored as this appears be important in patients who are chronic daily alcohol users.

This study examined whether patient-identified melanomas were more advanced than dermatologist-identified tumors at routine clinic visits, and whether a personal or family history of skin cancer was associated with patterns of detection. A retrospective chart review was performed on melanoma patients (N=201) in a private dermatology clinic. Variables included age, gender, pattern of detection (i.e., patient or a board certified dermatologist), personal or family history of skin cancer, skin type, and previous sun exposure, as well as tumor location and severity. Dermatologist-diagnosed melanomas were less invasive (P<0.0005), and more likely present on the chest, back, and legs (P<0.01). Conversely, patient-identified lesions were more likely to occur on the face, neck and scalp, be associated with younger patients, and a family history of melanoma, but not other types of skin cancer (P<0.01). In a post-hoc analysis examining these factors as predictors of tumor invasiveness, only diagnostic source was significant. Specifically, dermatologist-identified tumors were significantly less invasive than patient-identified tumors. Although age, family history, and tumor location played roles in the early detection of melanomas, the most important factor was diagnostic source. Thus, board-certified dermatologists play a key role in the early detection of malignant melanoma.

Background Often concussion/mTBI triggers a chronic headache syndrome called persistent post-traumatic headache (P-PTH) that can last from months to years post-injury, and produce significant disruption of childhood education, social interaction and development. Although prevalent and highly disabling, P-PTH is underrepresented in headache and pain research and lacks clear definition and pathophysiology. Clinical presentation of P-PTH frequently resembles that of other headache disorders, like migraine, yet the pathophysiological mechanisms are distinct and not fully understood, making the disorder difficult to treat in the clinical setting. Methods In a retrospective analysis of 1506 pediatric patients attending Boston Children’s Hospital clinics, demographic trends, symptom features, and the influence of sex on clinical presentation of PTH are presented. We compare clinical characteristics of P-PTH with a published cohort of migraine patients to evaluate the clinical features that are unique to P-PTH. Results Findings show that despite equivalent representation of sex in the clinic, P-PTH is expressed more in females than males and is weighted towards somatic symptoms. Relative to migraine, PTH is less associated with a family history of headache. Conclusions The ability to identify persons with PTH can help manage risk factors and identify persons likely to develop persistent post-concussion symptoms.
