Predictive capacity of a battery of neuropsychological tests in the early diagnosis of mild cognitive MCI/Capacidad predictiva de una batería de pruebas neuropsicológicas en el diagnóstico temprano del deterioro cognitivo leve (DCL) en un grupo de adultos
Authors: Londoño Ocampo León Paolo , Fuentes Oviedo Luis Miguel , Villalba Ceballos Farly
Published: June 2015

Se realizó un estudio denominado Capacidad predictiva de una batería de pruebas neuropsicológicas en el diagnóstico temprano del deterioro cognitivo leve (DCL) en un grupo de adultos. Los participantes fueron 12 adultos, padres de familia de estudiantes de la Institución Educativa La Rivera de Montería, con edades comprendidas entre los 27 y 36 años, con distintos grados de escolaridad y nivel socioeconómico. El diseño metodológico se basó en un enfoque cuantitativo tipo descriptivo. Se utilizó una batería de pruebas neuropsicológicas para evaluar atención, memoria, lenguaje, praxias, gnosias y función ejecutivas. Estas pruebas lograron determinar la presencia de síntomas preclínicos de DCL. Los defectos cognitivos identificados se pueden relacionar como marcadores cognitivos preclínicos. Otros estudios complementarios como una valoración neurológica, una Resonancia Magnética (RM) y una evaluación neuropsicológica cada 6 meses, ayudarían a diagnosticar el síndrome de manera definitiva y tomar medidas al respecto.
Public communication as a guiding strategy in citizen participation processes of youth/La comunicación pública como estrategia orientadora en los procesos de participación ciudadana de los jóvenes
Authors: Cuadros Rodríguez Jonatan Alejandro , Arias García Sebastián , Valencia Arias Alejandro
Published: June 2015

El presente artículo de investigación tiene como objetivo analizar el papel de los procesos de comunicación pública y participación ciudadana en la gestión que hacen las organizaciones gubernamentales, a fin de facilitar una comunicación más eficaz con los grupos de interés, que para el presente caso se enfoca en las comunidades jóvenes. La metodología planteada se basa en la indagación de fuentes secundarias de información alrededor del objetivo planteado a través de la búsqueda en bases de datos académicas y gubernamentales, las cuales se examinan con el objetivo de extraer las estrategias exitosas de comunicación y participación ciudadana de los jóvenes. Se concluye que dichos espacios generan la participación de los grupos de interés desde la toma activa de decisiones y el aprovechamiento de espacios públicos. Además, se deben buscar estrategias más allá del uso de medios masivos de comunicación; orientándose a propiciar el diálogo, la escucha y la satisfacción de necesidades de interés social en los grupos de intervención.
Economic Analysis of Cleft Palate Repair in International Adoptees
Authors: Tomlinson-Hansen Sandra , Paliga J. Thomas , Tahiri Youssef , Paine Kaitlyn M. , Bartlett Scott P. , Taylor Jesse A.
Published: June 2015

Design

Retrospective cohort study.

Setting

Major international tertiary care referral center for cleft palate repair.

Patients

One hundred thirty-eight patients at the Children's Hospital of Philadelphia who had palate repair performed between 2010 and 2013, excluding syndromic patients, patients undergoing palate revision, and patients with incomplete payment information.

Interventions

None.

Main Outcome Measure

Fees and charges for procedures.

Results

Surgeon payment was significantly higher for international adoptees (Δ = $2047.51 [$128.35 to $3966.66], P = .038). Medicaid-adjusted surgeon payments averaged $1006 more for adoptees ([-$394.19 to $2406.98], P = .158).

Conclusions

Hospital and anesthesiology costs for adoptee palate repair were highly variable but did not differ significantly from those for nonadoptees. Partly due to payer mix, surgeon reimbursement was somewhat higher for international adoptees. No difference in total payment was found.
Energy performance of windows under climate change in Turkey
Authors: Yıldız Yusuf
Published: June 2015

Windows are one of the thermally weakest parts of a building envelope and climate change is becoming an increasingly important parameter in evaluating the energy performance of buildings. This study investigated the effect of various window configurations on the energy behaviour of school buildings in three cities in Turkey based on climate change, orientation, glazing type and window size. Detailed parametric simulations were used and the results were compared in accordance with ISO 18292. The simulations indicate that the contribution of windows to cooling loads is highest when the value of the solar heat gain coefficient (SHGC) is high and its contribution increases due to climate change. The U-value of glazing is not as significant as the value of the SHGC for cooling. Orientation and window size are other important parameters that affect the energy performance of windows. In addition, in terms of energy costs and performance, it is more efficient for a building to be orientated in south or north directions.
Correlating strength of concrete to its early-age temperature rise
Authors: Jiang Chenhui , Yang Yang , Ni Tongyuan , Wang Xiaodong
Published: June 2015

Compressive strength is the most commonly used property for characterising the performance of concrete materials. In this study, semi-adiabatic temperature evolutions and compressive strength developments of a series of mortar and concrete mixtures were experimentally investigated. In order to predict compressive strength, it was correlated to the initial temperature rise induced by early-age hydration. The results indicate that both properties are strongly dependent on the raw materials and the water to cementitious materials ratio. Estimated results of temperature rise and strength from the modified equations match well with the measured data. A linear relationship between compressive strength and the peak value of temperature rise is developed and presented. The linear correlation exists for all mixture components and proportions of concrete materials in this study. In conclusion, predicting the strength of concrete materials from their early-age hydration-induced temperature evolutions is enabled.
Sewer risk management: reducing pollution using minimum gradient and GIS
Authors: Baker Maela
Published: June 2015

Blockages resulting from siltation build-up within the foul-combined sewer network can result in the occurrence of pollution incidences, especially during storm conditions. A common risk factor for such blockage events is pipes that have been laid at an insufficient gradient to achieve self-cleaning velocity. Inspection of such pipes is presently an inefficient and expensive process, requiring manual on-site inspection of sections, with all sewer networks deemed to be at risk even though not all such pipes will block. This paper outlines how the use of a geographical information system can be used to identify better areas of pollution susceptibility compared with the present minimum gradient system alone. Effective targeting of sewer cleansing using this method was found to not only reduce the likelihood of pollution events, but also allow for substantial cost savings by reducing the number of unnecessary site inspections prescribed using the minimum gradient system alone.
Models for accessing biomedical innovation in Asia
Authors: Kim Young-Hwa , Gautam Ajay
Published: June 2015

Asian countries are striving to transition into innovation-driven economies, and healthcare is a key sector on government agendas. Strong funding at academic institutions, high-impact publications, state-of-the-art clinical infra-structures, vast talent pools, increasing start-up activities and strengthening intellectual property regimes, all aligned with coherent government policies, is creating an evolving innovation ecosystem in countries such as China, South Ko-rea, Singapore, Taiwan and India. Such factors have fuelled a desire from global pharmaceutical companies to seek in-novation in Asia. In this article, we review the varied strategies of large multinationals using two key aspects—the capital investments and operational model—to understand such diverse approaches. Based on a qualitative and quantita-tive analysis, we have classified these strategies into four distinct approaches—“Captive”, “Partner”, “Service” and “Open” models—and discussed case studies that fit into each of these clusters. The model may provide global pharma-ceutical companies with a framework to evaluate their respective approaches for sourcing innovation and align them with the operational, financial, business and strategic needs of their organizations in Asia.
Education and Health: Building Indicators in International Comparison
Authors: De Broucker Patrice
Published: June 2015

Introduction: Nowadays, we often analyze the benefits of education as a sesame to access employment – the higher your level of education and better your field of study, the better your chances of getting quickly a stable, well paid and rewarding job. Surely this is important and it is a consideration that nobody can ignore when it comes to making a choice of a pathway through school and a career. But it would be inappropriate to think of education and its role in life only in such terms. Education is a source of many other benefits both for the individual and for society.
Parental and Peer Influences on Adolescent Smoking: A Literature Review
Authors: Mulvihill Cailin
Published: June 2015

Smoking cigarettes has been widely accepted as a negative health behaviour associated with many serious risks. Adolescent smoking is of particular interest from a public health perspective as the initiation of smoking in adolescence has been associated with higher addiction rates in adulthood. This review of the literature will examine the influence of social support networks, particularly parents and peers, on the initiation and escalation of adolescent smoking. The influence of social support networks primarily operates through the social learning theory, in which the adolescent mimics the behaviour of those in their social network. The literature suggests that while parents are more influential in young adolescence, peers become the main source of influence in later adolescence through processes known as peer selection and peer influence. Parents can positively affect adolescents’ smoking behaviour through effective communication and maintenance of a healthy parent-child relationship. Peers can also positively influence smoking behaviour through the same mechanisms of peer influence and selection. Knowledge of how parents and peers influence adolescent smoking initiation and escalation can potentially assist in developing public health programming that targets this high-risk behaviour.
The Epidemiology of Ophthalmological Disease among School Age Children in Rural India
Authors: Velkers Clive , Turpin MacKenzie , Deonandan Raywat
Published: June 2015

Preventable blindness is one of the primary health concerns in rural India, yet little is known about the prevalence of eye disease among India's school-aged children. The clinical database of the Srikiran Institute of Ophthalmology, which describes clinicians' visits to schools in Kakinada, India, was analyzed retrospectively to determine the prevalence of eye disease among 8488 students aged 18 years and younger. Among diagnosed illnesses, basic refractory impingement (including degrees of astigmatism) was the most common, followed by squinting. Vitamin A deficiency was not a factor in any of the tested subjects.

Competing Earnings Announcements: Which Announcement Do Investors Process First?
Authors: Frederickson James R. , Zolotoy Leon
Published: June 2015

Consistent with investors having limited attention, we posit that when faced with competing earnings announcements, investors behave as if they queue the announcements based on a firm or earnings announcement attribute. We focus on two potential queuing attributes: (1) firm visibility, and (2) the expected cost of processing the earnings announcements. We find no support for queuing based on the latter, but find a statistically significant and economically meaningful queuing effect based on firm visibility. Earnings announcements made by firms that are more visible than a given firm—but not by firms that are less visible—mitigate the announcement window market response to that firm's unexpected earnings, with a corresponding magnification in its post-earnings announcement drift. Further, the effects of visibility-based queuing are more pronounced for days with greater clustering of earnings announcements. Additional analysis suggests that individual investors—not institutional investors—drive the queuing effect.
Job Autonomy and Counterproductive Behaviors in Chinese Accountants: The Role of Job-Related Attitudes
Authors: Brink Alisa G. , Emerson David J. , Yang Ling
Published: June 2015

Counterproductive behaviors are of concern for all organizations. In addition to explicit financial costs, these behaviors can be detrimental to interpersonal and intraorganizational dynamics and morale, and they can generate negative reputational effects. The accounting literature has long maintained that job autonomy is critical in allowing accountants to apply accounting standards. Prior accounting literature calls for research investigating job autonomy and accounting professionalism. This study answers that call for research. We employ structural equation modeling to evaluate a sample of experienced Chinese accountants from a variety of industries and find a direct, positive, and deleterious effect between job autonomy and counterproductive behaviors. However, this effect is compensated for and reversed by a set of indirect and advantageous effects exerted through the influence of job satisfaction and perceived organizational support.
Muddling Parity of an Energy Efficient Incentive—Through the Lens of “Change in Accounting Method”
Authors: Campbell Linda J. , Smith Pamela C. , Willis Veronda F.
Published: June 2015

The Internal Revenue Service issued guidance related to automatic changes in accounting methods for taxpayers taking a §179D deduction for Energy Efficient Commercial Building Property. However, while the accounting treatment of §179D may trigger a change in accounting method for some taxpayers, this is not uniform for all taxpayers. In this paper, we argue that with this guidance, the Treasury Department (and Congress, by initial approval of the tax law) has inadvertently broadened unequal tax treatment between different segments of qualified taxpayers attracted to this important energy efficient building incentive. Further, we suggest that the §179D deduction be modified to achieve taxpayer parity to further incentivize energy efficiency.
Corrective Bandage for Conservative Treatment of Metatarsus Adductus: Retrospective Study
Authors: Utrilla-Rodríguez Elia , Guerrero-Martínez-Cañavete María Jesús , Albornoz-Cabello Manuel , Munuera-Martínez Pedro V.
Published: June 2015

Background

Metatarsus adductus (MA) is the most common congenital foot deformity observed in children.

Objectives

The aims of this study were: (1) to analyze the evolution of a corrective bandage for semirigid MA in newborns and (2) to recommend the age interval at which to start treatment of MA with the corrective bandage alone, without the need of splints.

Design

An observational clinical study was conducted.

Methods

The study was conducted at Virgen Macarena University Hospital in Seville, Spain. Children born with semirigid MA at the hospital during the years 2010–2011 were included. Corrective bandaging was applied to all children until clinical correction of the deformity. Sex, laterality of the deformity, weight and length of the newborn, age at the start of treatment, antecedents related to the pregnancy and birth, type of treatment (bandaging, splints), and correction or no correction with bandaging alone were recorded. Age differences at the start of the bandaging treatment between children whose deformity was corrected with and without the need of splints were examined. The receiver operating characteristic curve method was applied to analyze the predictive ability of the age at the start of bandaging treatment relative to whether the deformity was corrected or not corrected with bandaging alone.

Results

The bandage achieved complete correction in 68.1% of the children and corrected the deformity more frequently in girls compared with boys. Of the 56 children who began the treatment within the first month of life, 92.8% achieved correction of the foot deformity with the corrective bandaging alone.

Limitations

Patients' follow-up time was only 2 years, so it was only feasible to analyze the corrective bandaging method over the short term and medium term.

Conclusions

Corrective bandages showed high effectiveness, particularly in girls, and overall when started within the first month of life.
Association of Rehabilitation Intensity for Stroke and Risk of Hospital Readmission
Authors: Andrews A. Williams , Li Dongmei , Freburger Janet K.
Published: June 2015

Background

Little is known about the use of rehabilitation in the acute care setting and its impact on hospital readmissions.

Objective

The objective of this study was to examine the association between the intensity of rehabilitation services received during the acute care stay for stroke and the risk of 30-day and 90-day hospital readmission.

Design

A retrospective cohort analysis of all acute care hospitals in Arkansas and Florida was conducted.

Methods

Patients (N=64,065) who were admitted for an incident stroke in 2009 or 2010 were included. Rehabilitation intensity was categorized as none, low, medium-low, medium-high, or high based on the sum and distribution of physical therapy, occupational therapy, and speech therapy charges within each hospital. Cox proportional hazards regression was used to estimate hazard ratios, controlling for demographic characteristics, illness severity, comorbidities, hospital variables, and state.

Results

Relative to participants who received the lowest intensity therapy, those who received higher-intensity therapy had a decreased risk of 30-day readmission. The risk was lowest for the highest-intensity group (hazard ratio=0.86; 95% confidence interval=0.79, 0.93). Individuals who received no therapy were at an increased risk of hospital readmission relative to those who received low-intensity therapy (hazard ratio=1.30; 95% confidence interval=1.22, 1.40). The findings were similar, but with smaller effects, for 90-day readmission. Furthermore, patients who received higher-intensity therapy had more comorbidities and greater illness severity relative to those who received lower-intensity therapy.

Limitations

The results of the study are limited in scope and generalizability. Also, the study may not have adequately accounted for all potentially important covariates.

Conclusions

Receipt of and intensity of rehabilitation therapy in the acute care of stroke is associated with a decreased risk of hospital readmission.
Massive cerebral swelling immediately after cranioplasty, a fatal and unpredictable complication: report of 4 cases
Authors: Sviri Gill E.
Published: June 2015

Cranioplasty after decompressive craniectomy (DC) is associated with increased morbidity, but the reported mortality rate is low. Recently, some authors have reported a rare unexplained complication of sudden death in association with massive cerebral edema immediately after cranioplasty.

The author reports on 4 patients who underwent cranioplasty after DC between January 2005 and August 2010 at his department and died because of massive cerebral edema immediately after uneventful surgery and anesthesia. All 4 of the new cases reported involved young male patients who underwent decompressive hemicraniectomy after traumatic brain injury. They developed massive cerebral swelling immediately after uneventful cranioplasty (3 patients) or after removal of an epidural hematoma several hours after surgery (1 patient). All 4 patients had a large skull defect and significantly sunken craniotomy site, and all were treated with a closed vacuum suction system that was placed under the scalp and kept open at the end of the cranioplasty procedure. After surgery, the patients' pupils became fixed and dilated, and brain CT scans showed massive brain edema. Despite emergency DC, the patients did not recover, and all 4 died. A MEDLINE search showed 8 similar cases that were reported previously.

Fatal cerebral swelling after uneventful cranioplasty is a distinct clinical entity, although it is unpredictable. It is postulated that a negative pressure difference from the elimination of atmospheric pressure that had been chronically applied on the injured sinking brain in combination with the negative pressure applied by the closed subgaleal suction drain may lead to a massive brain shift toward the cranioplasty site and initiate a fatal vasomotor reaction.
Quantitative contrast-enhanced ultrasound measurement of cerebrospinal fluid flow for the diagnosis of ventricular shunt malfunction

Published: June 2015

OBJECT

Cerebral shunt malfunction is common but often difficult to effectively diagnose. Current methods are invasive, involve ionizing radiation, and can be costly. The authors of this study investigated the feasibility of quantitatively measuring CSF flow in a shunt catheter using contrast-enhanced ultrasound.

METHODS

A syringe pump was used to push a solution of gas-filled microbubbles at specific flow rates through a shunt catheter while a high-frequency ultrasound imaging system was used to collect ultrasound images for offline processing. Displacement maps and velocity profiles were generated using a speckle-tracking method based on a cross-correlation algorithm. An additional correction factor, to account for a predictable underestimation and to adjust the measured flow rates, was calculated based on the geometry of the ultrasound imaging plane and assuming a simple model of laminar flow.

RESULTS

The developed method was able to differentiate between physiologically relevant flow rates, including no flow and 0.006 to 0.09 ml/min, with reasonable certainty. The quantitative measurement of flow rates through the catheter using this method was determined to be in good agreement with the expected flow rate.

CONCLUSIONS

This study demonstrated that contrast-enhanced ultrasound has the potential to be used as a minimally invasive and cost-effective alternative method for outpatient shunt malfunction diagnosis.
Bilateral versus unilateral interlaminar approach for bilateral decompression in patients with single-level degenerative lumbar spinal stenosis: a multicenter retrospective study of 175 patients on postoperative pain, functional disability, and patient satisfaction
Authors: den Boogert Hugo F. , Keers Joost C. , Marinus Oterdoom D. L. , Kuijlen Jos M. A.
Published: June 2015

OBJECT

The bilateral and unilateral interlaminar techniques for bilateral decompression both demonstrate good results for the treatment of degenerative lumbar spinal stenosis (DLSS). Although there is some discussion about which approach is more effective, studies that directly compare these two popular techniques are rare. To address this shortcoming, this study compares postoperative functional disability, pain, and patient satisfaction among patients with single-level DLSS who underwent bilateral decompression using either a bilateral or unilateral approach.

METHODS

This retrospective study included patients who underwent operations between November 1, 2009, and October 1, 2011. These patients underwent single-level bilateral decompressive surgery using either the bilateral or unilateral interlaminar approach at one of 5 participating hospitals. Exclusion criteria included previous lumbar surgery, additional disc surgery, and spondylolisthesis requiring fusion surgery. Primary outcome measures included bodily pain (as reported using the visual analog scale [VAS]), the Roland-Morris Disability Questionnaire (RMDQ), and the Oswestry Disability Index (ODI). In addition, reductions in leg and back symptoms and the patient’s general evaluation of the procedure were queried. Finally, patient satisfaction and surgical parameters were evaluated. Questionnaires were sent to each patient’s home, and electronic patient files were used to collect the data.

RESULTS

One hundred and seventy-five patients returned the questionnaire (74.4% response rate; 68 and 107 patients who underwent the bilateral or unilateral approach, respectively). Mean age at surgery was 68 years (range 34–89 years), and the mean follow-up period was 14.2 months (range 3.3–27.4 years). There were no significant differences in ODI (20.3 vs 22.6 for the bilateral and unilateral approaches, respectively), RMDQ (3.99 vs 4.8, respectively), or pain scores between treatment groups. Back symptoms were reduced in 74.8% (bilateral: 74.6% vs unilateral: 75%; not significant), and leg symptoms in 80.6% of the patients (bilateral: 73.1% vs unilateral: 85.4%; p = 0.048). In total, 72.1% (bilateral) and 80.0% (unilateral) of patients reported good overall treatment results (p = 0.226). Significantly more patients in the unilateral group reported a better overall satisfaction with the procedure (82.1% vs 69.1%; p = 0.047).

CONCLUSIONS

There were no differences in postoperative functional disability and pain between the surgical techniques. The significant differences in patient satisfaction and reduction in leg symptoms were unrelated to surgical technique. The overall treatment results were satisfactory. Both techniques are safe and effective options for treating patients with single-level DLSS.
A controlled anterior sequential interbody dilation technique for correction of cervical kyphosis
Authors: Lau Darryl , Ziewacz John E. , Le Hai , Wadhwa Rishi , Mummaneni Praveen V.
Published: June 2015

OBJECT

Cervical kyphosis can lead to spinal instability, spinal cord injury, and disability. The correction of cervical kyphosis is technically challenging, especially in severe cases. The authors describe the anterior sequential interbody dilation technique for the treatment of cervical kyphosis and evaluate perioperative outcomes, degree of correction, and long-term follow-up outcomes associated with the technique.

METHODS

In the period from 2006 to 2011, a consecutive cohort of adults with cervical kyphosis (Cobb angles ≥ 0°) underwent sequential interbody dilation, a technique entailing incrementally increased interbody distraction with the sequential placement of larger spacers (at least 1 mm) in the discectomy and/or corpectomy spaces. The authors retrospectively reviewed these patients, and primary outcomes of interest included kyphosis correction, blood loss, hospital stay, complications, Nurick grade, pain, reoperation, and pseudarthrosis. A subgroup analysis among patients with preoperative kyphosis of 0°–9° (mild), 10°–19° (moderate), and ≥ 20° (severe) was performed.

RESULTS

One hundred patients were included in the study: 74 with mild preoperative cervical kyphosis, 19 with moderate, and 7 with severe. The mean patient age was 53.1 years, and 54.0% of the patients were male. Mean estimated blood loss was 305.6 ml, and the mean length of hospital stay was 5.2 days. The overall complication rate was 9.0%, and there were no deaths. Sixteen percent of patients underwent supplemental posterior fusion. There was significant correction in cervical alignment (p < 0.001), and the mean overall kyphosis correction was 12.4°. Patients with severe preoperative kyphosis gained a correction of 24.7°, those with moderate kyphosis gained 17.8°, and those with mild kyphosis gained 10.1°. A mean correction of 32.0° was obtained if 5 levels were addressed. The mean follow-up was 26.8 months. The reoperation rate was 4.7%. At follow-up, there was significant improvement in visual analog scale neck pain (p = 0.020) and Nurick grade (p = 0.037). The pseudarthrosis rate was 6.3%.

CONCLUSIONS

Sequential interbody dilation is a feasible and effective method of correcting cervical kyphosis. Complications and reoperation rates are low. Similar benefits are seen among all severities of kyphosis, and greater correction can be achieved in more severe cases.
Mobile pediatric neurosurgery: rapid response neurosurgery for remote or urgent pediatric patients

Published: June 2015

OBJECT

Time-critical neurosurgical conditions require urgent operative treatment to prevent death or neurological deficits. In New South Wales/Australian Capital Territory patients’ distance from neurosurgical care is often great, presenting a challenge in achieving timely care for patients with acute neurosurgical conditions.

METHODS

A protocol was developed to facilitate consultant neurosurgery locally. Children with acute, time-critical neurosurgical emergencies underwent operations in hospitals that do not normally offer neurosurgery. The authors describe the developed protocol, the outcome of its use, and the lessons learned in the 9 initial cases where the protocol has been used. Three cases are discussed in detail.

RESULTS

Nine children were treated by a neurosurgeon at 5 rural hospitals, and 2 children were treated at a smaller metropolitan hospital. Road ambulance, fixed wing aircraft, and medical helicopters were used to transport the Newborn and Paediatric Emergency Transport Service (NETS) team, neurosurgeon, and patients.

In each case, the time to definitive neurosurgical intervention was significantly reduced. The median interval from triage at the initial hospital to surgical start time was 3:55 hours, (interquartile range [IQR] 03:29–05:20 hours). The median distance traveled to reach a patient was 232 km (range 23–637 km). The median interval from the initial NETS call requesting patient retrieval to surgical start time was 3:15 hours (IQR 00:47–03:37 hours). The estimated median “time saved” was approximately 3:00 hours (IQR 1:44–3:15 hours) compared with the travel time to retrieve the child to the tertiary center: 8:31 hours (IQR 6:56–10:08 hours).

CONCLUSIONS

Remote urgent neurosurgical interventions can be performed safely and effectively. This practice is relevant to countries where distance limits urgent access for patients to tertiary pediatric care. This practice is lifesaving for some children with head injuries and other acute neurosurgical conditions.
Conservative treatment of cysts of the cavum septum pellucidum presenting in childhood: report of 3 cases
Authors: Bot Gyang Markus , Constantini Shlomi , Roth Jonathan
Published: June 2015

Cavum septum pellucidum (CSP) cysts are relatively rare. The most common presenting symptom is headache, which is thought to be secondary to elevated intracranial pressure. Many CSP cysts are treated surgically; conservative treatment is seldom recommended. The authors describe 3 cases of pediatric CSP cysts that were managed without surgery.

The patients ranged in age from 5 months to 8 years old. Two presented with headaches, which were associated with mild ventricular enlargement in 1 case. Over the course of 5–15 months, 2 cysts became markedly reduced in size, and in one of these 2 cases a substantial reduction in ventricle size was also observed. At last follow-up, all 3 children were asymptomatic.

The authors note that CSP cysts are often associated with headaches. In the absence of hydrocephalus, they recommend conservative management with clinical and radiological follow-up.
