RESUMEN

ABSTRACT. Normal-pressure hydrocephalus (NPH) is a potentially reversible syndrome characterized by enlarged cerebral ventricles (ventriculomegaly), cognitive impairment, gait apraxia and urinary incontinence. A critical review of the concept, pathophysiology, diagnosis, and treatment of both idiopathic and secondary NPH was conducted. We searched Medline and PubMed databases from January 2012 to December 2018 using the keywords "normal-pressure hydrocephalus" / "idiopathic normal-pressure hydrocephalus" / "secondary normal-pressure hydrocephalus" / "NPH" / "ventriculoperitoneal shunt". The initial search produced 341 hits. After careful selection, a total of 54 articles were chosen and additional relevant studies were included during the process of writing this article. NPH is an important cause of potentially reversible dementia, frequent falls and recurrent urinary infections in the elderly. The clinical and imaging features of NPH may be incomplete or nonspecific, posing a diagnostic challenge for medical doctors and often requiring expert assessment to minimize unsuccessful surgical treatments. Recent advances resulting from the use of non-invasive MRI methods for quantifying cerebral blood flow, in particular arterial spin-labeling (ASL), and the frequent association of NPH and obstructive sleep apnea (OSA), offer new avenues to understand and treat NPH.


RESUMO. A hidrocefalia de pressão normal (HPN) é uma síndrome potencialmente reversível marcada por ventrículos cerebrais alargados (ventriculomegalia), declínio cognitivo, apraxia da marcha e incontinência urinária. Revisar criticamente o conceito, a fisiopatologia, o diagnóstico e o tratamento da HPN idiopática e secundária. Os autores acessaram as bases de dados Medline e Pubmed entre janeiro de 2012 e dezembro de 2018, utilizando as palavras-chave "normal-pressure hydrocephalus" / "idiopathic normal-pressure hydrocephalus" / "secondary normal-pressure hydrocephalus" / "NPH" / "ventriculoperitoneal shunt". A busca inicial resultou em 341 artigos. Após cuidadosa seleção, 54 estudos foram escolhidos e pesquisas adicionais foram incluídas durante o processo de elaboração do manuscrito. A HPN é uma importante causa de demência potencialmente reversível, quedas frequentes e infecção urinária recorrente em idosos. As características clínicas e de imagem da HPN podem ser incompletas ou inespecíficas, de modo que este se torna um diagnóstico difícil para médicos. Não raro uma avaliação por especialista é necessária, visando minimizar tratamentos cirúrgicos ineficazes. Avanços recentes advindos do uso não invasivo de ressonância magnética para quantificação do fluxo sanguíneo cerebral, em particular arterial spin-labeling (ASL), assim como a usual associação entre HPN e apneia obstrutiva do sono representam novos meios de entender e de tratar a HPN.

RESUMEN

@#BACKGROUND: The objective of this study is to determine if point-of-care ultrasound (POCUS) pre-procedure identification of landmarks can decrease failure rate, reduce procedural time, and decrease the number of needle redirections and reinsertions when performing a lumbar puncture (LP).METHODS: This was a prospective, randomized controlled trial comparing POCUS pre-procedure identifi cation of landmarks versus traditional palpation for LP in a cohort of patients in the emergency department and intensive care unit.RESULTS: A total of 158 patients were enrolled. No signifi cant difference was found in time to completion, needle re-direction, or needle re-insertion when using POCUS when compared to the traditional method of palpation.CONCLUSION: Consistent with fi ndings of previous studies, our data indicate that there was no observed benefi t of using POCUS to identify pre-procedure landmarks when performing an LP.

RESUMEN

Mastocytosis is characterized by an accumulation of mast cells in various organs, most frequently in the skin. A solitary mastocytoma is a clinical variant of cutaneous mastocytosis. It is defined as a localized collection of mast cells in the skin without evidence of extracutaneous organ involvement. Here we report on a 2-year-old female patient presenting with Solitary erythematous bulla on her lower back. The patient had a history of spinal tap on the lower back for evaluation of meningitis at 5 months of age, which resulted in trauma at the site. Histopathology showed mast cells infiltrating the papillary and reticular dermis and metachromatic purple cytoplasmic granules seen with Giemsa staining. As a result, the patient was diagnosed with a solitary bullous mastocytoma and administered antihistamine. The patient showed complete remission at 3 months. Herein, we report a rare case of solitary bullous mastocytoma occurring at a trauma site.

RESUMEN

PURPOSE: Lumbar puncture is an essential and commonly practiced diagnostic tool and post-lumbar puncture headache and post-lumbar puncture back pain are common neurological complications. The aim of this study is to identify the factors that might cause post-lumbar puncture back pain and to reduce those complaints by eliminating the causes. METHODS: From June 5, 2013 to July 29, 2013, we studied 155 patients, male and female between the age 1 and 18,who received diagnostic or therapeutic lumbar puncture at Pusan National University Hospital and Pusan National University Yangsan Hospital. We collected data of variable aspects that may influence post-lumbar puncture back pain, by reviewing the medical records retrospectively. The independent variables were sex, age, symptoms, diagnosis, number of trials to successful lumbar puncture, year of the resident who carried out the procedure, opening pressure of cerebrospinal fluid(CSF), spinal level of punctured site, duration of strict bed rest, and use of sedatives for the procedure. RESULTS: Among the 155 patients whounderwent lumbar puncture, 36 (23.2%) experienced back pain after the procedure. Back pain subsided within 48hours in 24 ofthe 36 patients. Only one patient suffered from post-lumbar puncture back pain for more than 5days. There is no clear causality between the occurrence rate of post-lumbar puncture back pain and the independent variables which includeage, sex, duration of bed rest, symptoms, diagnosis, number of trials, skill, opening pressure, anatomic location, and use of sedatives. CONCLUSION: Back pain was a frequent complication of lumbar puncture. Various factors we expected to influence on the incidence of post-lumbar puncture back pain had no statistical significance. Further studies should be performed to investigate the causes and risk factors of post-lumbar puncture back pain.

RESUMEN

A 63 year-old female was brought to our hospital with severe lower back pain. She received antihypertensive drugs for 2 years but her blood pressure was normal upon arrival. She could not stand up or even walk. The MRI showed a subdural hematoma at the thoracolumbar region, which was extremely rare. The treatment applied was decompression through a spinal tap without surgery. After this, her pain subsided considerably. Two weeks later, MRI confirmed that there was no hematoma in the same region. She was discharged and has enjoyed her daily activities free of pain. A spontaneous subdural hematoma is an extremely rare disease. The condition was treated successfully in a conservative manner.
