Preoperative word-finding difficulties in children with posterior fossa tumours: a European cross-sectional study.

PURPOSE: Posterior fossa tumour surgery in children entails a high risk for severe speech and language impairments, but few studies have investigated the effect of the tumour on language prior to surgery. The current crosslinguistic study addresses this gap. We investigated the prevalence of preoperative word-finding difficulties, examined associations with medical and demographic characteristics, and analysed lexical errors. METHODS: We included 148 children aged 5-17 years with a posterior fossa tumour. Word-finding ability was assessed by means of a picture-naming test, Wordrace, and difficulties in accuracy and speed were identified by cut-off values. A norm-based subanalysis evaluated performance in a Swedish subsample. We compared the demographic and medical characteristics of children with slow, inaccurate, or combined slow and inaccurate word finding to the characteristics of children without word-finding difficulties and conducted a lexical error analysis. RESULTS: Thirty-seven percent (n = 55) presented with slow word finding, 24% (n = 35) with inaccurate word finding, and 16% (n = 23) with both slow and inaccurate word finding. Children with posterior fossa tumours were twice as slow as children in the norming sample. Right-hemisphere and brainstem location posed a higher risk for preoperative word-finding difficulties, relative to left-hemisphere location, and difficulties were more prevalent in boys than in girls. The most frequent errors were lack of response and semantically related sideordinated words. CONCLUSION: Word-finding difficulties are frequent in children with posterior fossa tumours, especially in boys and in children with right-hemisphere and brainstem tumours. Errors resemble those observed in typical development and children with word-finding difficulties.

Risk factors associated with nausea and vomiting in children with cancer receiving chemotherapy.

INTRODUCTION: Despite treatment with antiemetic medications, nausea remains uncontrolled for many children receiving chemotherapy. One reason is that risk factors for nausea in children remain poorly explored. The purpose of this study was to identify risk factors for chemotherapy-induced nausea (CIN) in children. METHODS: Prospective, observational study including 101 children (median age 6.4 years, range 0.8-17.9) with cancer receiving moderately or highly emetogenic chemotherapy. Primary endpoints were complete control of acute and delayed CIN, defined as no nausea in the acute phase 0-24 h after chemotherapy and in the delayed phase starting after the acute phase and ending 5 days later. Multivariable analyses included age, sex, cancer type, susceptibility to motion sickness, chemotherapy duration, numbers of antiemetics, co-administration with opioids or tricyclic antidepressants, and previously uncontrolled nausea or vomiting. RESULTS: Acute CIN was associated with susceptibility to motion sickness (odds ratio [OR] 5.73, 95% confidence interval [CI] 1.36-33.7) and older age (OR 4.19, 95% CI 1.30-14.7), comparing age group 8-18 years with 0-3 years. Delayed CIN was associated with uncontrolled acute nausea or vomiting (OR 10.3, 95% CI 2.65-50.9), highly emetogenic chemotherapy (OR 8.26, 95% CI 1.17-76.8), and having a hematologic cancer type (OR 7.81, 95% CI 1.05-79.2). CONCLUSIONS: Susceptibility to motion sickness and age can influence the risk of acute CIN. More research is needed on how best to integrate risk information in preventive antiemetic strategies. Sufficient acute nausea and vomiting control are crucial to prevent delayed CIN.

Postoperative speech impairment and cranial nerve deficits after secondary surgery of posterior fossa tumours in childhood: a prospective European multicentre study.

PURPOSE: Brain tumours constitute 25% of childhood neoplasms, and half of them are in the posterior fossa. Surgery is a fundamental component of therapy, because gross total resection is associated with a higher progression-free survival. Patients with residual tumour, progression of residual tumour or disease recurrence commonly require secondary surgery. We prospectively investigated the risk of postoperative speech impairment (POSI) and cranial nerve dysfunction (CND) following primary and secondary resection for posterior cranial fossa tumours. METHODS: In the Nordic-European study of the cerebellar mutism syndrome, we prospectively included children undergoing posterior fossa tumour resection or open biopsy in one of the 26 participating European centres. Neurological status was assessed preoperatively, and surgical details were noted post-operatively. Patients were followed up 2 weeks, 2 months and 1 year postoperatively. Here, we analyse the risk of postoperative speech impairment (POSI), defined as either mutism or reduced speech, and cranial nerve dysfunction (CND) following secondary, as compared to primary, surgery. RESULTS: We analysed 426 children undergoing primary and 78 undergoing secondary surgery between 2014 and 2020. The incidence of POSI was significantly lower after secondary (12%) compared with primary (28%, p = 0.0084) surgery. In a multivariate analysis adjusting for tumour histology, the odds ratio for developing POSI after secondary surgery was 0.23, compared with primary surgery (95% confidence interval: 0.08-0.65, p = 0.006). The frequency of postoperative CND did not differ significantly after primary vs. secondary surgery (p = 0.21). CONCLUSION: Children have a lower risk of POSI after secondary than after primary surgery for posterior fossa tumours but remain at significant risk of both POSI and CND. The present findings should be taken in account when weighing risks and benefits of secondary surgery for posterior fossa tumours.

Peptic ulcers in the elderly is a surgical disease.

BACKGROUND: Operative management for peptic ulcer disease (PUD) has changed significantly over the last 30 years. METHODS: For a 15-year period, records of patients undergoing operative management for peptic ulcer disease were stratified into age groups and examined with respect to presentation, type of operation, and risk factors. RESULTS: In all, 154 patients underwent surgery for PUD during the 1990s. Elderly patients were more likely to require an emergent operation (91%, P = 0.005), present with hemodynamic instability (25%, P = 0.025), and have a longer hospital stay (21 days, P = 0.012). Among the elderly in the 1990s as compared with the 1980s, there was increased use of nonsteroidal anti-inflammatory drugs ([NSAIDs] (49%, P = 0.005), decreased tobacco use (22%, P = 0.014), and less likelihood of postoperative renal failure (6%, P = 0.014). CONCLUSIONS: Elderly patients in the 1990s comprise the majority of cases presenting in a more unstable condition as compared with patients <60 years old, but show similar rates of morbidity and mortality. Elderly patients undergoing surgery for PUD have shown an increase in use of NSAIDs over the last 15 years. The types of procedures have not changed, but operations are more likely to be an emergent basis.

Pituitary lymphoma: a case report and literature review.

We report the case of a B-cell type pituitary lymphoma in a 65 year-old male immunocompetent patient who presented with hypogonadotropic hypogonadism and central hypothyroidism and subsequently developed pulmonary lymphoma. Only three cases of pituitary lymphoma have been previously reported, one in a patient with acquired immunodeficiency syndrome, one case of T-cell lymphoma reported in the Japanese literature, and one case of B-cell lymphoma. The previously reported immunocompetent patients presented with signs and symptoms of optic chiasm compression as contrasted to our patient's endocrinologic presentation. B-cell lymphoma of the pituitary gland is a exceedingly rare though distinct clinical entity.

Congenital teratoma of the oropharyngeal cavity with intracranial extension: case report and literature review.

Congenital teratoma of the oropharyngeal cavity is a unique clinical entity that poses immediate threats to the neonate in the postpartum period. Establishment of a secure airway is a primary goal after delivery; complete surgical resection is the subsequent guiding principle of management. Even more rare than teratomas confined to the oropharynx are tumors that extend into the intracranial cavity during development. Descriptions of these lesions in the medical literature are uncommon. In the majority of these reports, the tumors are associated with stillbirth, perinatal death, or significant morbidity after attempted resection. We present the rare case of a patient with congenital oropharyngeal teratoma with intracranial extension who has demonstrated long-term survival without any neurological or functional deficits. A unique delayed staged approach to resection of the extracranial and intracranial components of the tumor is described.
