We report on 19 individuals with a recurrent de novo c.607C>T mutation in PACS1. This specific mutation gives rise to a recognizable intellectual disability syndrome. There is a distinctive facial appearance (19/19), characterized by full and arched eyebrows, hypertelorism with downslanting palpebral fissures, long eye lashes, ptosis, low set and simple ears, bulbous nasal tip, wide mouth with downturned corners and a thin upper lip with an unusual “wavy” profile, flat philtrum, and diastema of the teeth. Intellectual disability, ranging from mild to moderate, was present in all. Hypotonia is common in infancy (8/19). Seizures are frequent (12/19) and respond well to anticonvulsive medication. Structural malformations are common, including heart (10/19), brain (12/16), eye (10/19), kidney (3/19), and cryptorchidism (6/12 males). Feeding dysfunction is presenting in infancy with failure to thrive (5/19), gastroesophageal reflux (6/19), and gastrostomy tube placement (4/19). There is persistence of oral motor dysfunction. We provide suggestions for clinical work‐up and management and hope that the present study will facilitate clinical recognition of further cases. © 2016 Wiley Periodicals, Inc.

Professionalism requires that doctors acknowledge their errors and figure out how to avoid making similar ones in the future. Over the last few decades, doctors have gotten better at acknowledging mistakes and apologizing to patients when a mistake happens. Such disclosure is especially complicated when one becomes aware of an error made by a colleague. We present a case in which consultant surgeons became aware that a colleague seemed to have made a serious error. Experts in surgery and bioethics comment on appropriate responses to this situation.

Abstract Purpose: We examined the hypothesis that mutations in mTOR pathway genes are associated with response to rapalogs in metastatic renal cell carcinoma (mRCC). Experimental Design: We studied a cohort of mRCC patients who were treated with mTOR inhibitors with distinct clinical outcomes. Tumor DNA from 79 subjects was successfully analyzed for mutations using targeted next-generation sequencing of 560 cancer genes. Responders were defined as those with partial response (PR) by RECIST v1.0 or stable disease with any tumor shrinkage for 6 months or longer. Nonresponders were defined as those with disease progression during the first 3 months of therapy. Fisher exact test assessed the association between mutation status in mTOR pathway genes and treatment response. Results: Mutations in MTOR, TSC1, or TSC2 were more common in responders, 12 (28%) of 43, than nonresponders, 4 (11%) of 36 (P = 0.06). Mutations in TSC1 or TSC2 alone were also more common in responders, 9 (21%), than nonresponders, 2(6%), (P = 0.05). Furthermore, 5 (42%) of 12 subjects with PR had mutations in MTOR, TSC1, or TSC2 compared with 4 (11%) of 36 nonresponders (P = 0.03). Eight additional non-mTOR pathway genes were found to be mutated in at least 4 of 79 tumors (5%); none were associated positively with response. Conclusions: In this cohort of mRCC patients, mutations in MTOR, TSC1, or TSC2 were more common in patients who experienced clinical benefit from rapalogs than in those who progressed. However, a substantial fraction of responders (24 of 43, 56%) had no mTOR pathway mutation identified. Clin Cancer Res; 22(10); 2445–52. ©2016 AACR. See related commentary by Voss and Hsieh, p. 2320

Advancing age is associated with an increased risk of herpes zoster (shingles) infection and latent effects such as postherpetic neuralgia. The herpes zoster vaccine is recommended in those 60 years of age and older and has been shown to prevent both the primary disease and associated complications. While this recommendation applies to those living in long-term care facilities, there is little clinical evidence to support use in this population. Additionally, there are logistical barriers that may complicate the use of the vaccine. The article examines the evidence for vaccinating residents in long-term care facilities and discusses logistical barriers to vaccination. Pharmacists and providers may consider life expectancy and other factors when evaluating which patients should receive the vaccination.

Long-acting injectable antipsychotics provide the delivery of medication over an extended period of time requiring administration typically only every 2 to 4 weeks. The side effect profile of a long-acting injectable antipsychotic is predictable and similar to the oral formulation. However, injection site reactions may occur with this novel delivery system. The risk of an injection site reaction may be greater with the repeated administration of a lipophilic decanoate formulation and include pain, development of indurations, and fibrosis. Severe complications from injection site reactions have rarely been described in the literature with newer agents. We report the first case of a patient prescribed paliperidone palmitate every 3 weeks that developed severe sepsis requiring vasopressors and intubation due to delayed relayed recognition of a necrotizing infection at an injection site. Clinicians should be alerted to screen for injection site reactions when there is an unknown source infection in a patient receiving a long-acting injectable antipsychotic.

ObjectiveInfantile spasms are seizures associated with a severe epileptic encephalopathy presenting in the first 2 years of life, and optimal treatment continues to be debated. This study evaluates early and sustained response to initial treatments and addresses both clinical remission and electrographic resolution of hypsarrhythmia. Secondarily, it assesses whether response to treatment differs by etiology or developmental status.MethodsThe National Infantile Spasms Consortium established a multicenter, prospective database enrolling infants with new diagnosis of infantile spasms. Children were considered responders if there was clinical remission and resolution of hypsarrhythmia that was sustained at 3 months after first treatment initiation. Standard treatments of adrenocorticotropic hormone (ACTH), oral corticosteroids, and vigabatrin were considered individually, and all other nonstandard therapies were analyzed collectively. Developmental status and etiology were assessed. We compared response rates by treatment group using chi‐square tests and multivariate logistic regression models.ResultsTwo hundred thirty infants were enrolled from 22 centers. Overall, 46% of children receiving standard therapy responded, compared to only 9% who responded to nonstandard therapy (p < 0.001). Fifty‐five percent of infants receiving ACTH as initial treatment responded, compared to 39% for oral corticosteroids, 36% for vigabatrin, and 9% for other (p < 0.001). Neither etiology nor development significantly modified the response pattern by treatment group.InterpretationResponse rate varies by treatment choice. Standard therapies should be considered as initial treatment for infantile spasms, including those with impaired development or known structural or genetic/metabolic etiology. ACTH appeared to be more effective than other standard therapies. ANN NEUROL 2016;79:475–484

AbstractObjectiveThe objectives were to assess the feasibility of using a novel, comprehensive chaplain‐led spiritual life review interview to develop a personal Spiritual Legacy Document (SLD) for persons with brain tumors and other neurodegenerative diseases and to describe spiritual well‐being (SWB), spiritual coping, and quality of life (QOL) of patients and their support persons (SP) before and after receipt of the SLD.MethodsPatient‐SP pairs were enrolled over a 2‐year period. Assessments included the Functional Assessment of Chronic Illness Therapy‐Spiritual Expanded Version, Brief Religious Coping Scale, Brief COPE Inventory, and QOL Linear Analog Scale. Baseline assessments were completed prior to an audio‐recorded spiritual life review interview with a chaplain.ResultsThirty‐two patient/SP pairs were enrolled; 27 completed baseline assessments and the interview. Twenty‐four reviewed their SLD and were eligible for follow‐up. A total of 15 patients and 12 SPs completed the 1‐month follow‐up; 10 patients and seven SPs completed the 3‐month follow‐up. Patients endorsed high levels of SWB and spiritual coping at baseline. Both patients and SPs evidenced improvement on several aspects of SWB, spiritual coping, and QOL at 1 month, but patients' decreased financial well‐being was also observed. Patients and SPs demonstrated favorable changes in peacefulness and positive religious coping at both time points.ConclusionsA chaplain‐led spiritual life review is a feasible intervention for patients with neurodegenerative disease and results in beneficial effects on patients and SPs.

AbstractBackgroundOveruse of computed tomography (CT) for minor head injury continues despite developed and rigorously validated clinical decision rules like the Canadian CT Head Rule (CCHR). Adherence to this sensitive and specific rule could decrease the number of CT scans performed in minor head injury by 35%. But in practice, the CCHR has failed to reduce testing, despite its accurate performance.ObjectivesThe objective was to identify nonclinical, human factors that promote or inhibit the appropriate use of CT in patients presenting to the emergency department (ED) with minor head injury.MethodsThis was a qualitative study in three phases, each with interview guides developed by a multidisciplinary team. Subjects were recruited from patients treated and released with minor head injuries and providers in an urban academic ED and a satellite community ED. Focus groups of patients (four groups, 22 subjects total) and providers (three groups, 22 subjects total) were conducted until thematic saturation was reached. The findings from the focus groups were triangulated with a cognitive task analysis, including direct observation in the ED (>150 hours), and individual semistructured interviews using the critical decision method with four senior physician subject matter experts. These experts are recognized by their peers for their skill in safely minimizing testing while maintaining patient safety and engagement. Focus groups and interviews were audio recorded and notes were taken by two independent note takers. Notes were entered into ATLAS.ti and analyzed using the constant comparative method of grounded theory, an iterative coding process to determine themes. Data were double‐coded and examined for discrepancies to establish consensus.ResultsFive core domains emerged from the analysis: establishing trust, anxiety (patient and provider), constraints related to ED practice, the influence of others, and patient expectations. Key themes within these domains included patient engagement, provider confidence and experience, ability to identify and manage patient anxiety, time constraints, concussion knowledge gap, influence of health care providers, and patient expectations to get a CT.ConclusionsDespite high‐quality evidence informing use of CT in minor head injury, multiple factors influence the decision to obtain CT in practice. Identifying and disseminating approaches and designing systems that help clinicians establish trust and manage uncertainty within the ED context could optimize CT use in minor head injury.
