Great advances have been made during the last 20 years in the development of structured and semi-structured interviews for use with psychiatric patients. However, in the field of child and adolescent psychiatry there have been weaknesses in the specification and definition of both symptoms and the psychosocial impairments resulting from psychiatric disorder. Furthermore, most of the available interviews for use with children have been tied to a single diagnostic system (DSM-III, DSM-III-R, or ICD-9). This has meant that symptom coverage has been limited and nosological comparisons have been inhibited. The Child and Adolescent Psychiatric Assessment (CAPA) represents an attempt to remedy some of these shortcomings. This paper outlines the principles adopted in the CAPA to improve the standardization, reliability and meaningfulness of symptom and diagnostic ratings. The CAPA is an interviewer-based diagnostic interview with versions for use with children and their parents, focused on symptoms occurring during the preceding 3 month period, adapted for assessments in both clinical and epidemiological research.

A natural history study of pneumococcal infection in 82 infants followed from birth is reported. Longitudinal carriage patterns were determined by serial throat and nasopharyngeal cultures. Seventy-nine of 82 infants carried one or more types during the study period. The first type was acquired by a mean age of six months, and the duration of carriage decreased with successive types carried. Acquisition of new types peaked in winter months, but carriage rates fluctuated throughout the year. Thirty-one pneumococcal infections were documented in 24 infants: 28 episodes of otitis media, two of bacteremia, and one of meningitis. Types causing disease were similar to commonly carried types (6, 14, 19 and 23). However, infection usually occurred within one month of acquisition of a new type and was seldom associated with prolonged carriage. In terms of exposure to new strains, 15% (31 of 196) of acquisitions resulted in disease.

BACKGROUND: The Primary Immune Deficiency Treatment Consortium was formed to analyze the results of hematopoietic-cell transplantation in children with severe combined immunodeficiency (SCID) and other primary immunodeficiencies. Factors associated with a good transplantation outcome need to be identified in order to design safer and more effective curative therapy, particularly for children with SCID diagnosed at birth. METHODS: We collected data retrospectively from 240 infants with SCID who had received transplants at 25 centers during a 10-year period (2000 through 2009). RESULTS: Survival at 5 years, freedom from immunoglobulin substitution, and CD3+ T-cell and IgA recovery were more likely among recipients of grafts from matched sibling donors than among recipients of grafts from alternative donors. However, the survival rate was high regardless of donor type among infants who received transplants at 3.5 months of age or younger (94%) and among older infants without prior infection (90%) or with infection that had resolved (82%). Among actively infected infants without a matched sibling donor, survival was best among recipients of haploidentical T-cell-depleted transplants in the absence of any pretransplantation conditioning. Among survivors, reduced-intensity or myeloablative pretransplantation conditioning was associated with an increased likelihood of a CD3+ T-cell count of more than 1000 per cubic millimeter, freedom from immunoglobulin substitution, and IgA recovery but did not significantly affect CD4+ T-cell recovery or recovery of phytohemagglutinin-induced T-cell proliferation. The genetic subtype of SCID affected the quality of CD3+ T-cell recovery but not survival. CONCLUSIONS: Transplants from donors other than matched siblings were associated with excellent survival among infants with SCID identified before the onset of infection. All available graft sources are expected to lead to excellent survival among asymptomatic infants. (Funded by the National Institute of Allergy and Infectious Diseases and others.).

Poor outcomes in COVID-19 correlate with clinical and laboratory features of cytokine storm syndrome. Broad screening for cytokine storm and early, targeted antiinflammatory therapy may prevent immunopathology and could help conserve limited health care resources. While studies are ongoing, extrapolating from clinical experience in cytokine storm syndromes may benefit the multidisciplinary teams caring for patients with severe COVID-19.

Acute disseminated encephalomyelitis (ADEM) is an immune-mediated inflammatory disorder of the CNS characterized by a widespread demyelination that predominantly involves the white matter of the brain and spinal cord. The condition is usually precipitated by a viral infection or vaccination. The presenting features include an acute encephalopathy with multifocal neurologic signs and deficits. Children are preferentially affected. In the absence of specific biologic markers, the diagnosis of ADEM is still based on the clinical and radiologic features. Although ADEM usually has a monophasic course, recurrent or multiphasic forms have been reported, raising diagnostic difficulties in distinguishing these cases from multiple sclerosis (MS). The International Pediatric MS Study Group proposes uniform definitions for ADEM and its variants. We discuss some of the difficulties in the interpretation of available literature due to the different terms and definitions used. In addition, this review summarizes current knowledge of the main aspects of ADEM, including its clinical and radiologic diagnostic features, epidemiology, pathogenesis, and outcome. An overview of ADEM treatment in children is provided. Finally, the controversies surrounding pediatric MS and ADEM are addressed.

PURPOSE: In the Children's Oncology Group, risk group assignment for neuroblastoma is critical for therapeutic decisions, and patients are stratified by International Neuroblastoma Staging System stage, MYCN status, ploidy, Shimada histopathology, and diagnosis age. Age less than 365 days has been associated with favorable outcome, but recent studies suggest that older age cutoff may improve prognostic precision. METHODS: To identify the optimal age cutoff, we retrospectively analyzed data from the Pediatric Oncology Group biology study 9047 and Children's Cancer Group studies 321p1-p4, 3881, 3891, and B973 on 3,666 patients (1986 to 2001) with documented ages and follow-up data. Twenty-seven separate analyses, one for each different age cutoff (adjusting for MYCN and stage), tested age influence on outcome. The cutoff that maximized outcome difference between younger and older patients was selected. RESULTS: Thirty-seven percent of patients were younger than 365 days, and 64% were > or = 365 days old (4-year event-free survival [EFS] rate +/- SE: 83% +/- 1% [n = 1,339] and 45% +/- 1% [n = 2,327], respectively; P < .0001). Graphical analyses revealed the continuous nature of the prognostic contribution of age to outcome. The optimal 460-day cutoff we selected maximized the outcome difference between younger and older patients. Forty-three percent were younger than 460 days, and 57% were > or = 460 days old (4-year EFS rate +/- SE: 82% +/- 1% [n = 1,589] and 42% +/- 1% [n = 2,077], respectively; P < .0001). Using a 460-day cutoff (assuming stage 4, MYCN-amplified patients remain high-risk), 5% of patients (365 to 460 days: 4-year EFS 92% +/- 3%; n = 135) fell into a lower risk group. CONCLUSION: The prognostic contribution of age to outcome is continuous in nature. Within clinically relevant risk stratification, statistical support exists for an age cutoff of 460 days.

Burst abdomen and incisional herniation are continuing problems for the general surgeon. A prospective study was carried out to define the extent of the problem. Over five years from 1975 to 1980 a total of 1129 major laparotomy wounds in adults were assessed at regular intervals for 12 months after operation. There were 19 burst abdomens (1.7%) and 84 incisional hernias (7.4%). The introduction of the mass-closure technique reduced the incidence of burst abdomen from over 3% in 1975 to 0.95% in 1979. It did not, however, improve the rate for incisional hernias, which was 7.6% in 1979. Many factors are associated with incisional herniation: old age, male sex, obesity, bowel surgery, type of suture, chest infection, abdominal distension, and, most important, wound infection. More work is needed to find the ideal method of wound closure, and efforts should be made to eliminate wound infection.

As the prevalence of obesity and obesity-related disease among adolescents in the United States continues to increase, physicians are increasingly faced with the dilemma of determining the best treatment strategies for affected patients. This report offers an approach for the evaluation of adolescent patients' candidacy for bariatric surgery. In addition to anthropometric measurements and comorbidity assessments, a number of unique factors must be critically assessed among overweight youths. In an effort to reduce the risk of adverse medical and psychosocial outcomes and increase compliance and follow-up monitoring after bariatric surgery, principles of adolescent growth and development, the decisional capacity of the patient, family structure, and barriers to adherence must be considered. Consideration for bariatric surgery is generally warranted only when adolescents have experienced failure of ≥6 months of organized weight loss attempts and have met certain anthropometric, medical, and psychologic criteria. Adolescent candidates for bariatric surgery should be very severely obese (defined by the World Health Organization as a body mass index of ≥40), have attained a majority of skeletal maturity (generally ≥13 years of age for girls and ≥15 years of age for boys), and have comorbidities related to obesity that might be remedied with durable weight loss. Potential candidates for bariatric surgery should be referred to centers with multidisciplinary weight management teams that have expertise in meeting the unique needs of overweight adolescents. Surgery should be performed in institutions that are equipped to meet the tertiary care needs of severely obese patients and to collect long-term data on the clinical outcomes of these patients.

Vitamin D functions are not limited to skeletal health benefits and may extend to preservation of insulin secretion and insulin sensitivity. This review summarizes the literature related to potential vitamin D influences on glucose homeostasis and insulin sensitivity. Cross-sectional data provide some evidence that circulating 25-hydroxyvitamin D (25(OH)D) is inversely associated with insulin resistance, although direct measurements of insulin sensitivity are required for confirmation. Reported associations with insulin secretion, however, are contradictory. Available prospective studies support a protective influence of high 25(OH)D concentrations on type 2 diabetes mellitus risk. There is a general lack of consistency in vitamin D intervention outcomes on insulin secretion and sensitivity, likely due to differences in subject populations, length of interventions, and forms of vitamin D supplementation. Vitamin D receptor gene polymorphisms and vitamin D interactions with the insulin like growth factor system may further influence glucose homeostasis. The ambiguity of optimal vitamin D dosing regimens and optimal therapeutic concentrations of serum 25(OH)D limit available intervention studies. Future studies, including cross-sectional and prospective, should be performed in populations at high risk for both vitamin D deficiency and type 2 diabetes mellitus. Well-designed, placebo-controlled, randomized intervention studies are required to establish a true protective influence of vitamin D on glucose homeostasis.

Recurrent respiratory papillomatosis (RRP), which is caused by human papillomavirus types 6 and 11, is the most common benign neoplasm of the larynx among children and the second most frequent cause of childhood hoarseness. After changes in voice, stridor is the second most common symptom, first inspiratory and then biphasic. Less common presenting symptoms include chronic cough, recurrent pneumonia, failure to thrive, dyspnea, dysphagia, or acute respiratory distress, especially in infants with an upper respiratory tract infection. Differential diagnoses include asthma, croup, allergies, vocal nodules, or bronchitis. Reports estimate the incidence of RRP in the United States at 4.3 per 100,000 children and 1.8 per 100,000 adults. Infection in children has been associated with vertical transmission during vaginal delivery from an infected mother. Younger age at diagnosis is associated with more aggressive disease and the need for more frequent surgical procedures to decrease the airway burden. When surgical therapy is needed more frequently than four times in 12 months or there is evidence of RRP outside the larynx, adjuvant medical therapy should be considered. Adjuvant therapies that have been investigated include dietary supplements, control of extra-esophageal reflux disease, potent antiviral and chemotherapeutic agents, and photodynamic therapies; although several have shown promise, none to date has "cured" RRP, and some may have serious side effects. Because RRP, although histologically benign, is so difficult to control and can cause severe morbidity and death, better therapies are needed. The potential for a quadrivalent human papilloma vaccine is being explored to reduce the incidence of this disease.

OBJECTIVE: To examine the safety and efficacy of the interleukin-1 (IL-1) receptor antagonist anakinra as first-line therapy for systemic juvenile idiopathic arthritis (JIA). METHODS: Patients with systemic JIA receiving anakinra as part of initial disease-modifying antirheumatic drug (DMARD) therapy were identified from 11 centers in 4 countries. Medical records were abstracted using a standardized instrument, and resulting data were analyzed to characterize concomitant therapies, clinical course, adverse events, and predictors of outcome. RESULTS: Among 46 patients meeting inclusion criteria, anakinra monotherapy was used in 10 patients (22%), while 67% received corticosteroids and 33% received additional DMARDs. Outcomes were evaluated at a median followup interval of 14.5 months. Fever and rash resolved within 1 month in >95% of patients, while C-reactive protein and ferritin normalized within this interval in >80% of patients. Active arthritis persisted at 1 month in 39% of patients, at 3 months in 27%, and at >6 months of followup in 11%. Approximately 60% of patients, including 8 of 10 receiving anakinra monotherapy, attained a complete response without escalation of therapy. Disease characteristics and treatment were similar in partial and complete responders, except that partial responders were markedly younger at onset (median age 5.2 years versus 10.2 years; P = 0.004). Associated adverse events included documented bacterial infection in 2 patients and hepatitis in 1 patient. Tachyphylaxis was not observed. CONCLUSION: Anakinra as first-line therapy for systemic JIA was associated with rapid resolution of systemic symptoms and prevention of refractory arthritis in almost 90% of patients during the interval examined. These results justify further study of IL-1 inhibition as first-line, rather than rescue, therapy in systemic JIA.

CONTEXT: Vaccine development to prevent congenital cytomegalovirus (CMV) infection has been impeded by the uncertainty over whether maternal immunity protects the fetus. OBJECTIVE: To determine whether the presence of maternal antibodies to CMV significantly reduces the risk of congenital CMV infection in future pregnancies. DESIGN, SETTING, AND PARTICIPANTS: Cohort study of 3461 multiparous women from a population with a high rate of congenital CMV infection who delivered newborns screened for congenital CMV infection between 1993 and 1998, and whose cord serum specimen from a previous delivery could be retrieved and tested for antibody to CMV. MAIN OUTCOME MEASURE: Congenital CMV infection according to maternal immune status, age, race, parity, and socioeconomic status. RESULTS: Of 604 newborns born to initially seronegative mothers, congenital CMV infection occurred in 18 (3.0%). In contrast, of 2857 newborns born to immune mothers, congenital CMV infection occurred in 29 (1.0%) Two factors, preconception maternal immunity (adjusted risk ratio, 0.31; 95% confidence interval, 0.17-0.58) and maternal age of 25 years or older (adjusted risk ratio, 0.19; 95% confidence interval, 0.07-0.49), were highly protective against congenital CMV infection. No other factors were associated with a reduction in the risk of congenital CMV infection. CONCLUSION: Naturally acquired immunity results in a 69% reduction in the risk of congenital CMV infection in future pregnancies.

One hundred and thirty-four adults and 204 children were randomized in two prospective, parallel comparative multicentre trials to receive either conventional amphotericin B 1 mg/kg/d (c-AMB), liposomal amphotericin B 1 mg/kg/d(L-AMB1) or liposomal amphotericin B 3 mg/ kg/d (L-AMB3). Patients were entered if they had a pyrexia of unknown origin (PUO) defined as temperature of 38 degrees C or more, not responding to 96 h of systemic broad-spectrum antibiotic treatment, and neutropenia (< 0.5 x 10(9)/l). The safety and toxicity of liposomal amphotericin B was compared with that of conventional amphotericin B. Efficacy of treatment was assessed, with success defined as resolution of fever for 3 consecutive days (< 38 degrees C) without the development of any new fungal infection. Clinical and laboratory parameters were collected for safety analysis. In both the paediatric and adult populations, L-AMB treated patients had a 2-6-fold decrease in the incidence (P < or = 0.01) of test-drug-related side-effects, compared to c-AMB. Severe trial-drug-related side-effects were seen in 1% of L-AMB treated patients, in contrast to 12% of patients on c-AMB (P < 0.01). Nephrotoxicity, in the patient subset not receiving concomitant nephrotoxic agents, defined as a doubling from the patients baseline serum creatinine level, was not observed in the L-AMB1 arm whereas the incidence was 3% in patients on L-AMB3 and 23% in those on c-AMB (P < 0.01). Moreover, time to develop nephrotoxicity was longer in both L-AMB arms than c-AMB (P < 0.01). Severe hypokalaemia was observed less frequently in both L-AMB arms (P < 0.01). Analysis was by intention-to-treat and included all patients randomized. Success was defined by a minimum of 3 consecutive days with fever (< 38 degrees C) continuing to study end indicated by recovery of neutrophils to 0.5 x 10(9)/l. Addition of systemic antifungal therapy or development of systemic fungal infection were failures as was persistent fever to study end. Efficacy assessments indicated success in 49% of the total group treated with c-AMB, 58% of patients responded to L-AMB1 and 64% to L-AMB3. A statistically significant difference was found between c-AMB and L-AMB3 (P = 0.03) but a Kaplan-Meier analysis of time to differvescence of fever showed there was no significant difference between the arms. It was concluded that liposomal amphotericin at either 1 or 3 mg/kg/d was significantly safer than conventional amphotericin B in children and adults. The main aim of this open-label study was to compare safety between the three trial arms. However, we provide evidence for an equivalent or possibly superior efficacy of liposomal amphotericin with regard to resolution of fever of unknown origin. Subsequent trials should compare amphotericin preparations in defined fungal infections.

BACKGROUND: Therapeutic hypothermia is recommended for comatose adults after witnessed out-of-hospital cardiac arrest, but data about this intervention in children are limited. METHODS: We conducted this trial of two targeted temperature interventions at 38 children's hospitals involving children who remained unconscious after out-of-hospital cardiac arrest. Within 6 hours after the return of circulation, comatose patients who were older than 2 days and younger than 18 years of age were randomly assigned to therapeutic hypothermia (target temperature, 33.0°C) or therapeutic normothermia (target temperature, 36.8°C). The primary efficacy outcome, survival at 12 months after cardiac arrest with a Vineland Adaptive Behavior Scales, second edition (VABS-II), score of 70 or higher (on a scale from 20 to 160, with higher scores indicating better function), was evaluated among patients with a VABS-II score of at least 70 before cardiac arrest. RESULTS: A total of 295 patients underwent randomization. Among the 260 patients with data that could be evaluated and who had a VABS-II score of at least 70 before cardiac arrest, there was no significant difference in the primary outcome between the hypothermia group and the normothermia group (20% vs. 12%; relative likelihood, 1.54; 95% confidence interval [CI], 0.86 to 2.76; P=0.14). Among all the patients with data that could be evaluated, the change in the VABS-II score from baseline to 12 months was not significantly different (P=0.13) and 1-year survival was similar (38% in the hypothermia group vs. 29% in the normothermia group; relative likelihood, 1.29; 95% CI, 0.93 to 1.79; P=0.13). The groups had similar incidences of infection and serious arrhythmias, as well as similar use of blood products and 28-day mortality. CONCLUSIONS: In comatose children who survived out-of-hospital cardiac arrest, therapeutic hypothermia, as compared with therapeutic normothermia, did not confer a significant benefit in survival with a good functional outcome at 1 year.

Accumulation of α-synuclein (α-syn) in the brain is a core feature of Parkinson disease (PD) and leads to microglial activation, production of inflammatory cytokines and chemokines, T-cell infiltration, and neurodegeneration. Here, we have used both an <i>in vivo</i> mouse model induced by viral overexpression of α-syn as well as <i>in vitro</i> systems to study the role of the MHCII complex in α-syn-induced neuroinflammation and neurodegeneration. We find that <i>in vivo</i>, expression of full-length human α-syn causes striking induction of MHCII expression by microglia, while knock-out of MHCII prevents α-syn-induced microglial activation, antigen presentation, IgG deposition, and the degeneration of dopaminergic neurons. <i>In vitro</i>, treatment of microglia with aggregated α-syn leads to activation of antigen processing and presentation of antigen sufficient to drive CD4 T-cell proliferation and to trigger cytokine release. These results indicate a central role for microglial MHCII in the activation of both the innate and adaptive immune responses to α-syn in PD and suggest that the MHCII signaling complex may be a target of neuroprotective therapies for the disease.

REPORTS of the clinical efficacy of acyclovir, a selective and specific inhibitor of herpesvirus replication, appeared in the literature a decade ago. Acyclovir has become the most widely prescribed and clinically effective antiviral drug available, and research on new indications is ongoing. This review will summarize our current understanding of the indications as well as the limitations of acyclovir therapy.Mechanism of Action and Spectrum of Antiviral ActivityAcyclovir (9-[2-hydroxyethoxymethyl]guanine) is a selective inhibitor of the replication of herpes simplex virus (HSV) types 1 and 2 and varicella–zoster virus.1 , 2 It is converted by virus-encoded thymidine kinase to its monophosphate derivative, . . .

OBJECTIVE: To determine the effect of acyclovir and prednisone treatment of herpes zoster on chronic pain and quality-of-life outcomes. DESIGN: Randomized, double-blind, placebo-controlled study with a 2 x 2 factorial design. SETTING: 15 university hospitals or affilliated clinics. PATIENTS: 208 immunocompetent patients older than 50 years of age who had localized herpes zoster that developed less than 72 hours before study enrollment. INTERVENTION: Acyclovir or a matched placebo was administered orally, 800 mg five times daily, for 21 days. Prednisone or a matched placebo was administered orally at 60 mg/d for the first 7 days, 30 mg/d for days 8 to 14, and 15 mg/d for days 15 to 21. The four treatments regimens given were acyclovir plus prednisone; acyclovir plus prednisone placebo; prednisone plus acyclovir placebo; and placebos for both acyclovir and prednisone. MEASUREMENTS: Patients were monitored daily for the first 28 days for lesion healing, resolution of pain, return to usual activity, and return to uninterrupted sleep. Monitoring was then done monthly for 6 months. Patients documented analgesic requirements each day, and adverse events and laboratory abnormalities were recorded at each clinical visit. An intention-to-treat analysis was used. RESULTS: Patients were randomly allocated to receive one of the four regimens. Demographic characteristics were similar for each group. Time to total crusting and healing was accelerated for patients receiving acyclovir plus prednisone compared with patients receiving two placebos; the risk ratios were 2.27 (95% Cl, 1.46 to 3.55) for total crusting and 2.07 (Cl, 1.26 to 3.38) for healing. Similarly, compared with the placebo group, patients receiving acyclovir plus prednisone had accelerated time to cessation of acute neuritis (risk ratio, 3.02 [Cl, 1.42 to 6.41]), time to return to uninterrupted sleep (risk ratio, 2.12 [Cl, 1.25 to 3.58]); time to return to usual daily activity (risk ratio, 3.22 [Cl, 1.92 to 5.40]); and time to cessation of analgesic therapy (risk ratio, 3.15 [Cl, 1.69 to 5.89]). In the acyclovir plus prednisone group, resolution of pain during the 6 months after disease onset did not statistically differ from that in the other groups. No important clinical or laboratory adverse events occurred in any group. CONCLUSIONS: In relatively healthy persons older than 50 years of age who have localized herpes zoster, combined acyclovir and prednisone therapy can improve quality of life.

Although the term Hesselbach's triangle is used in everyday general surgical practice, little is written and known regarding the life of the early surgical pioneer for whom it is named. The present paper reviews the life of the German Franz Kaspar Hesselbach (1759--1816) and his contributions to the anatomical sciences and practice of surgery.

OBJECT: The diagnosis and treatment of Chiari malformation Type I (CM-I) has evolved over the last few decades. The authors present their surgical experience of over 2 decades of treating children with this form of hindbrain herniation. METHODS: The authors conducted a retrospective review of their institutional experience with the surgical treatment of the pediatric CM-I from 1989 to 2010. RESULTS: The 2 most common presentations were headache/neck pain (40%) and scoliosis (18%). Common associated diagnoses included neurofibromatosis Type 1 (5%) and idiopathic growth hormone deficiency (4.2%). Spine anomalies included scoliosis (18%), retroversion of the odontoid process (24%), Klippel-Feil anomaly (3%), and atlantooccipital fusion (8%). Approximately 3% of patients had a known family member with CM-I. Hydrocephalus was present in 48 patients (9.6%). Syringomyelia was present in 285 patients (57%), and at operation, 12% of patients with syringomyelia were found to have an arachnoid veil occluding the fourth ventricular outlet. Fifteen patients (3%) have undergone reoperation for continued symptoms or persistent large syringomyelia. The most likely symptoms and signs to resolve following surgery were Valsalva-induced headache and syringomyelia. The average hospital stay and "return to school" time were 3 and 12 days, respectively. The follow-up for this group ranged from 2 months to 15 years (mean 5 years). Complications occurred in 2.4% of cases; there was no mortality. No patient required acute return to the operating room, and no blood transfusions were performed. CONCLUSIONS: The authors believe this to be the largest reported series of surgically treated pediatric CM-I patients and hope that their experience will be of use to others who treat this surgical entity.

Cytomegalovirus is the most common cause of congenital and perinatal viral infections throughout the world. Congenital infection occurs in 1% of all live births in developed countries and in an even higher percentage in developing nations. As a result of transmission during birth, by breast milk, and by blood transfusion, perinatal infections are much more prevalent than congenital infections. The vast majority of these infections are chronic, subclinical forms, but symptomatic infections are sufficiently prevalent and dangerous to represent a major unsolved public health problem throughout the world. In this review the epidemiologic, clinical, immunologic, and therapeutic facets of cytomegaloviral infections in pregnant women and their offspring will be discussed.
