Abstract
An important step in the performance of endoscopic resection of colloid cysts of the third ventricle is the forced aspiration of cyst contents. The different consistencies these cysts may have can limit their complete resection and increase the likelihood of complications. The introduction of the ultrasonic neuroendoscopic aspirator allows cysts to be emptied more easily than with a conventional rigid aspirator, improving the feasibility of resection even in more solid cysts. The ability to regulate ultrasound and aspiration increases safety in a reduced and highly morbid space such as the third ventricle. Our objective was to determine the safety and efficiency of the ultrasonic aspirator for endoscopic resection of colloid cysts of the third ventricle. This was a retrospective descriptive study of patients with colloid cysts of the third ventricle undergoing neuroendoscopic resection using an ultrasonic aspirator between 2016-2023. Clinical, radiological, and procedural variables were studied. Mean, median and range were analyzed for quantitative variables and percentages and frequencies for qualitative variables. We present a series of 11 patients with colloid cysts of the third ventricle. The mean age was 44 years (27-69). All had biventricular hydrocephalus, with a mean cyst diameter of 15 mm (9-20). The lateral ventricle was accessed using the transforaminal approach in seven patients and the transchoroidal approach in three patients. All patients underwent septostomy. The mean endoscopy time was 40 min (29-68). Complete resection was possible in 10 patients. Median follow-up was 16 months (1-65) with 100% clinical improvement. At the end of follow-up, no patient had recurrence of the lesion. Based on our experience, the ultrasonic aspirator can be used safely and effectively for the resection of colloid cysts of the third ventricle, achieving high rates of complete resection with minimal postoperative complications.

Abstract
Intracranial hypertension may be idiopathic or due to multiple etiologies. Some bone dysplasias and chronic shunt overdrainage syndrome may sometimes lead to intracranial hypertension associated with craniocerebral disproportion due to thickening of cranial diploe. The internal cranial expansion procedure has been used for patients with intracranial hypertension, whether or not associated with craniocerebral disproportion. Its purpose is to increase the intracranial volume by drilling down the inner table. This technique enables the craniocerebral disproportion to be improved and intracranial hypertension reduced. In other etiologies of intracranial hypertension with non-thickened diploe, internal cranial expansion may not be enough to resolve the hypertension. For these cases we propose a modification of the technique by expanding the cranial vault outwards; external cranial expansion. We describe this technique as used in a pediatric patient who presented with chronic headache, tonsillar ectopia, and sleep apnea syndrome. This patient also had a multisuture craniosynostosis, a non-thickened diploe, and intracranial hypertension.

Abstract
Gender equity is imperative to the attainment of healthy lives and wellbeing of all, and promoting gender equity in leadership in the health sector is an important part of this endeavour. This empirical research examines gender and leadership in the health sector, pooling learning from three complementary data sources: literature review, quantitative analysis of gender and leadership positions in global health organisations and qualitative life histories with health workers in Cambodia, Kenya and Zimbabwe. The findings highlight gender biases in leadership in global health, with women underrepresented. Gender roles, relations, norms and expectations shape progression and leadership at multiple levels. Increasing women's leadership within global health is an opportunity to further health system resilience and system responsiveness. We conclude with an agenda and tangible next steps of action for promoting women's leadership in health as a means to promote the global goals of achieving gender equity.

Abstract
AIM The aim of this study was to analyze risk factors for the development of hydrocephalus in newborn infants with germinal matrix (GM) hemorrhage. METHODS The study comprised 271 patients admitted to Carlos Haya University Hospital in Malaga with GM hemorrhage. The following data were recorded: gestational age, gender, twin birth, head circumference at birth, weight at birth, and Papile grade. Severe obstetrical (abruption, chorioamnionitis, pregnancy-induced hypertension, tocolytic treatment) and neonatal disorders (respiratory distress syndrome, neonatal infection, coagulation disorder, patent ductus arteriosus, necrotizing enterocolitis) were also recorded. Symptomatic hydrocephalus was diagnosed in the event of a progressive increase in head circumference and ventricular indices requiring shunting. RESULTS Of the 271 patients, 139 (51%) developed posthemorrhagic ventriculomegaly; 47 patients (17%) developed symptomatic hydrocephalus and needed shunt implantation. We found a significant relationship between the development of symptomatic hydrocephalus and Papile grade, lower gestational age, lower birth weight, twin birth, and neonatal infection. CONCLUSION Awareness of risk factors for the development of hydrocephalus in newborn infants with GM hemorrhage should be emphasized in order to enable an early diagnosis of ventriculomegaly and symptomatic hydrocephalus and thus make a correct therapeutic decision.

Abstract
PURPOSE Intraventricular hemorrhage is the most common cause of infantile acquired hydrocephalus. Our objective is to determine if the implantation of ventriculoperitoneal shunt in posthemorrhagic hydrocephalus as a primary and definitive neurosurgical treatment, with no previous temporary procedures, would decrease complication rates with good functional outcomes. METHODS Two hundred seventy-one patients with germinal matrix hemorrhage were diagnosed at the Carlos Haya Hospital between 2003 and 2010. Forty-seven patients underwent ventriculoperitoneal shunt after developing symptomatic hydrocephalus. The minimum weight required for shunt implantation was 1,500 g. We recorded complications related to the surgical procedure and analyzed functional state with a self-developed four-grade scale. RESULTS One hundred thirty-nine (51.3 %) patients with intraventricular hemorrhage developed ventricular dilatation, but only 47 patients (17.34 %) needed shunting. In seven cases, temporary neurosurgical procedures were performed, but in all of them, this was followed by ventriculoperitoneal shunt implantation. The infection rate was 4.25 %, and shunt obstruction rate was 4.25 %. More than 80 % of patients were classified as good or excellent functional state. Mean follow-up period was 38.75 months (SD, 27.09; range, 1-102 months). CONCLUSIONS Ventriculoperitoneal shunting as a primary neurosurgical treatment in posthemorrhagic hydrocephalus would decrease surgical morbidity with good functional outcome.

Abstract
Intraventricular haemorrhage and posthemorrhagic hydrocephalus are the most important neurological complications in preterm infants during the neonatal period. The prevalence of germinal matrix intraventricular haemorrhage widely varies depending on the population of study, but it is in any case increasing due both to the higher incidence of multiple and preterm deliveries as well as the longer survival of preterm infants favoured by recent advances in perinatal care. It is therefore of the utmost convenience to be familiar with the most important clinical evidence regarding this entity. However, the available evidence is often incomplete and piecemeal. The objective of the present review is to summarise the main diagnostic and therapeutic points regarding preterm related posthemorrhagic hydrocephalus. The participants of the working-group in Pediatric Neurosurgery of the Spanish Society of Neurosurgery were asked to write these recommendations down. This hopefully represents the first step towards the definition of a clinical guide in the treatment of complications related to periventricular hemorrhage of the preterm infants.

Abstract
Differential gene expression was analyzed after infection with Phytophthora infestans in six potato cultivars with different levels of resistance to late blight. To verify the infection of the potato leaflets, the amount of phytopathogen mRNA within the plant material was quantified by real-time quantitative PCR. The expression of 182 genes selected from two subtracted cDNA libraries was studied with cDNA array hybridization using RNA from non-infected and infected potato leaflets. Gene up- and down-regulation were clearly detectable in all cultivars 72 h post inoculation. Gene expression patterns in susceptible cultivars differed from those in potato varieties with a higher level of resistance. In general, a stronger gene induction was observed in the susceptible cultivars compared to the moderately to highly resistant potato varieties. Five genes with the highest homology to stress and/or defence-related genes were induced specifically in the susceptible cultivars. Four genes responded to pathogen attack independently of the level of resistance of the cultivar used, and three genes were repressed in infected tissue of most cultivars. Even in the absence of P. infestans infection, six genes showed higher expression levels in the somewhat resistant cultivars Bettina and Matilda. Possible reasons for the different levels of gene expression are discussed.

Abstract
INTRODUCTION AND CLINICAL CASES Three cases of central neurocytoma, confirmed by immunohistochemical study are reported. The central neurocytoma has recently been added to the differential diagnosis of intraventricular tumors. It is more frequent than previously thought, with high incidence in young patients. The positivity for synaptophysin and neuron specific enolase, the negativity for neurofilament protein and glial fibrillary acid protein, and the finding of elements of neuronal differentiation on electron microscopy, are the main pathological features of these tumors. CONCLUSION The surgical treatment is the election, and radiotherapy is reserved for malignant cases or recurrence.

Abstract
Spontaneous spinal epidural hematoma is an uncommon cause of cord compression. This lesion has been correlated with some precipitant factors, but frequently is idiopathic. It's a unusual process, more uncommon in children, and there are only 350 cases reported in the literature. Etiology is unknown and there are several theories about it. The clinical presentation is remarkably uniform, with local back and radicular pain followed by sensory and motor disfunction. Early diagnosis and treatment are very important for the functional recovery of the patient. In this article, the literature is reviewed, especially the etiological and therapeutic aspects, and two new cases are reported. These cases can help to define the etiology of this entity.
