Exocrine pancreatic insufficiency in long-term follow-up after curative gastric resection with D2 lymphadenectomy: A cross-sectional study

BackgroundExocrine pancreatic insufficiency (EPI) can be a problem following gastrectomies. This study aimed to reveal the EPI prevalence and its possible causes in gastric cancer patients that underwent subtotal or total gastrectomy, with completed oncological treatments, and with long-term disease-free survival success. Additionally, we also sought to determine whether there were any relations between EPI and blood biomarkers, weight change, malnutrition parameters, and quality of life after gastrectomy.MethodsA total of 69 gastric cancer patients whose oncological treatments had already been completed, with a minimum follow-up period of 16 months, were included in the study. Fecal samples were taken from all patients for the Fecal Elastase-1 Test, and patients were stratified into three groups based on the results: low (<100 μg/g), moderate (100–200 μg/g), and normal (>200 μg/g). These results were compared with patients’ clinical characteristics, blood nutrition biomarkers, Maastricht indexes (MI), Bristol stool scale, and Gastrointestinal Quality of Life Index (GIQLI) scores.ResultsFE-1 levels were low in 33 (47.8%) of the patients, moderate in 11 (15.9%), and normal in 25 (36.2%). The rate of patients receiving chemoradiotherapy (CRT) in the low FE-1 group was higher than the normal FE-1 and moderate FE-1 groups (P < 0.001 and P = 0.012, respectively). The serum total protein and lipase levels were lower in the low FE-1 group than in the normal FE-1 group (P = 0.023 and P < 0.001, respectively). When compared to the normal FE-1 group, the MI score of the low FE-1 group was higher (P = 0.018). The low FE-1 group had lower GIQLI gastrointestinal symptom scores than the normal FE-1 group (P = 0.046).ConclusionsDuring long-term follow-up, EPI can be seen in more than half of patients with gastric cancer after curative gastrectomy. Radiotherapy as an adjunct to adjuvant treatment in the postoperative period is considered a serious risk factor for EPI development. EPI contributes to malnutrition development after gastrectomy and negatively affects the patients’ quality of life, especially in terms of gastrointestinal symptoms.     

A study on clinical and radiological features and outcome in patients with posterior reversible encephalopathy syndrome (PRES)

Posterior reversible encephalopathy syndrome (PRES) is characterized clinically by headaches, seizures, vomiting, nausea, visual abnormalities, and altered mental function and is often (but not invariably) accompanied by parieto-occipital imaging features. The aim of this study is to describe the clinical and radiological features and outcome following PRES in a paediatric cohort. From a retrospectively identified cohort, case records were studied to confirm a diagnosis of PRES. Neuroimaging was reviewed again to assign to recently described radiological subtypes parieto-occipital pattern, holohemispheric watershed pattern, dominant superior frontal sulcus pattern, and asymmetrical or partial expression of the three primary patterns (A/P). Patient outcome was measured by the modified Rankin scale (mRS) scores. Nine boys and three girls with mean age of 12 were identified. Hypertensive episodes (n?=?11), tacrolimus toxicity (n?=?4), and autoimmunity (n?=?1) were identified as potential risk factors/etiologies. Their median mRS at the peak of illness was 2 (range 2–5); three children required intensive care support. After mean follow-up of 35 months (median 37 months; range 3–60 months), all patients improved significantly with mean mRS of 1 (median 1; range 0–1). Conclusion: PRES is easily recognizable by the clinical and radiological features. Although severe at presentation, the outcome from this condition is favorable.     

Urinary 1H-NMR and GC-MS metabolomics predicts early and late onset neonatal sepsis

The purpose of this article is to study one of the most significant causes of neonatal morbidity and mortality: neonatal sepsis. This pathology is due to a bacterial or fungal infection acquired during the perinatal period. Neonatal sepsis has been categorized into two groups: early onset if it occurs within 3–6 days and late onset after 4–7 days. Due to the not-specific clinical signs, along with the inaccuracy of available biomarkers, the diagnosis is still a major challenge. In this regard, the use of a combined approach based on both nuclear magnetic resonance (¹H-NMR) and gas-chromatography-mass spectrometry (GC-MS) techniques, coupled with a multivariate statistical analysis, may help to uncover features of the disease that are still hidden. The objective of our study was to evaluate the capability of the metabolomics approach to identify a potential metabolic profile related to the neonatal septic condition. The study population included 25 neonates (15 males and 10 females): 9 (6 males and 3 females) patients had a diagnosis of sepsis and 16 were healthy controls (9 males and 7 females). This study showed a unique metabolic profile of the patients affected by sepsis compared to non-affected ones with a statistically significant difference between the two groups (p = 0.05).     

Unrecognized atypical tuberous sclerosis diagnosed with CT

Summary Past experience in this hospital has shown that the neuroradiological diagnosis of tuberous sclerosis is often made before the diagnosis is clinically suspected. We present a child in such a circumstance in whom axial and coronal CT demonstrated significant neoplastic progression of this disease. The presenting symptom was merely that of increased intracranial pressure.     

MR imaging in mental retardation

Mental retardation is considered idiopathic or not otherwise specified when no etiological diagnosis can be identified in spite of comprehensive history, physical examination and metabolic or genetic investigations. In such cases, brain MRI is indicated for patients with abnormal head size or shape, craniofacial malformation, somatic anomalies, neurocutaneous findings, seizures, focal neurological findings or behavioral and/or developmental problems. Brain anomalies are now considered a main category for the etiology of mental retardation. MRI evaluation should include axial images of the entire brain, sagittal images through the midline structures, and coronal images of the posterior fossa or entire brain. MRI allows detection of major and or minor cerebral anomalies or malformations, sometimes multiple. In the literature, the most frequently involved structures include: 1/ corpus callosum (hypoplasia, short corpus callosum and verticalized splenium), 2/ septum pellucidum (cavum septum pellucidum or cavum vergae), 3/ ventricles (ventriculomegaly), 4/ cerebral cortex (cortical dysplasia), 5/ cerebellum (hypoplasia), and 6/ extra-axial CSF spaces (enlargement). In our patient population, dysplasia involving the cerebellum and vermis have been identified, a finding that has not yet been described in the literature. MRI allows detection of multiple minor morphological anomalies. Most have classically been considered as normal variants but they may in fact be markers of cerebral dysgenesis and are currently the only anomaly detected in the work-up of patients with mental retardation. Their role in the pathogenesis of mental retardation is under evaluation.     

Acute transverse myelitis in Lyme neuroborreliosis

Introduction  

Acute transverse myelitis (ATM) is a rare disorder (1–8 new cases per million of population per year), with 20% of all cases occurring in patients younger than 18 years of age. Diagnosis requires clinical symptoms and evidence of inflammation within the spinal cord (cerebrospinal fluid and/or magnetic resonance imaging). ATM due to neuroborreliosis typically presents with impressive clinical manifestations.     

Neonatal ruptured intracranial aneurysms: case report and literature review

Introduction  Intracranial aneurysms are exceptional in neonatal patients: There are only 16 cases previously reported. We describe the first case of neonatal posterior inferior cerebellar artery (PICA) aneurysm and review the literature. Case report  A 7-day-old girl presented with irritability, anorexia, fever and abnormally enlarging head circumference. Computed tomography (CT) and magnetic resonance (MR) imaging demonstrated intraventricular haemorrhage, secondary hydrocephalus and a pontine cistern haematoma. A PICA aneurysm was suspected on the CT angiogram (CTA) and the diagnosis was confirmed by conventional cerebral angiography. She was successfully treated by surgical clipping of the parent vessel and excision of the aneurysm. Postoperatively, she experienced transient swallowing difficulties and required a ventriculo-peritoneal shunt for hydrocephalus. Histopathological evaluation demonstrated a calcified arterial wall with thrombosis, signs of prior haemorrhage and the absence of the internal elastic lamina. Conclusion  Neonatal intracranial aneurysms are rare. Clinical presentation of subarachnoid haemorrhage in this age group is often non-specific. First-line investigation should start with transfontanelle cranial ultrasound, followed by MR angiography then CTA if necessary. Posterior circulation aneurysms and large or giant aneurysms are more frequent in neonates and children than in adults. Early diagnosis and treatment are important for improved outcome. Surgery is better tolerated than in adults.     

When to image neurologically normal children with headaches: development of a decision rule

Aims: The aim of this study was to develop and refine a decision rule on when to undertake brain imaging (BI) in neurologically normal children with headaches. Methods: From the literature and a questionnaire study, a list of red flags (RFs) was drawn‐up. During the prospective 4‐year period, consecutive children with headache were classified according to RFs and the headache diagnosis. Result: Three of 709 (0.4%) neurologically normal children had significant brain abnormalities. BI was carried out in 389 of 498 (78%) children with RFs. Significant abnormalities were found in three of 389 children (0.8%), all had unclassified headache (UH). BI was not arranged for the 211 children with no RFs. None of these developed RFs or abnormal signs on follow‐up for a mean of 13 months. Conclusion: In addition to BI for those with neurological signs, we think BI should be considered for neurologically normal patients with UH and RFs. This would have saved imaging children needlessly: only 101 of 709 (14%) would have had scans arranged, instead of 389 of 709.
