Among the various disorders that manifest with gait disturbance, cognitive impairment, and urinary incontinence in the elderly population, idiopathic normal pressure hydrocephalus (iNPH) is becoming of great importance. The first edition of these guidelines for management of iNPH was published in 2004, and the second edition in 2012, to provide a series of timely, evidence-based recommendations related to iNPH. Since the last edition, clinical awareness of iNPH has risen dramatically, and clinical and basic research efforts on iNPH have increased significantly. This third edition of the guidelines was made to share these ideas with the international community and to promote international research on iNPH. The revision of the guidelines was undertaken by a multidisciplinary expert working group of the Japanese Society of Normal Pressure Hydrocephalus in conjunction with the Japanese Ministry of Health, Labour and Welfare research project. This revision proposes a new classification for NPH. The category of iNPH is clearly distinguished from NPH with congenital/developmental and acquired etiologies. Additionally, the essential role of disproportionately enlarged subarachnoid-space hydrocephalus (DESH) in the imaging diagnosis and decision for further management of iNPH is discussed in this edition. We created an algorithm for diagnosis and decision for shunt management. Diagnosis by biomarkers that distinguish prognosis has been also initiated. Therefore, diagnosis and treatment of iNPH have entered a new phase. We hope that this third edition of the guidelines will help patients, their families, and healthcare professionals involved in treating iNPH.

Pharmaceutical consultation targeting outpatients at the Fujita Health University Hospital (Japan) provides support to patients undergoing anticancer drug treatment. This study aimed to explore factors that affect the comprehension of cancer chemotherapy among outpatients who received cancer treatment at our hospital. A questionnaire survey was conducted, and comprehension was scored on a scale of 1–5 (1, no comprehension; 5, full comprehension). When factors other than age and sex [the influence of which on comprehension has been reported in previous reports] were noted, differences in comprehension between the questionnaire items were comparatively analyzed according to the presence/absence of the relevant factors. Overall, 536 patients were included. Age (<70 years) and pharmacist interventions were identified as factors contributing to a comprehension score. The levels of comprehension regarding the name of the cancer chemotherapy, content/schedule of the treatment, purposes of the prescribed drugs, and objectives of blood tests were significantly higher in the group that received the pharmaceutical interventions; conversely, the level of comprehension for the self-management of adverse events was significantly lower in this group than in the group that did not receive any pharmaceutical interventions. Age and interventions by the pharmacist affected the comprehension of cancer chemotherapy by patients.

Long-acting injection (LAI) is a drug administration method that reduces symptoms and prevents recurrence or relapse of schizophrenia. We examined factors related to the continuation of LAI treatment. The study population included patients with schizophrenia who were undergoing LAI treatment involving risperidone, paliperidone, or aripiprazole at Fujita Health University Hospital between October 2009 and June 2017. We assessed the continuation rate of LAI treatment at six months, and collected patient characteristics such as medication history. Furthermore, we classified patients into two clusters according to the reason for introducing LAI based on a previous study (Prog. Neuropsychopharmacol. Biol. Psychiatry, 2008, Heres et al.). The study included 82 patients (mean age, 44.9 ± 15.0 years); the continuation rate of LAI after six months was 63.4%. Factors that affected LAI continuation included cluster II [adjusted odds ratio (OR): 5.74, p = 0.017], switching from the same component as LAI (adjusted OR: 7.13, p < 0.001), and diazepam conversion rate (adjusted OR: 0.88, p < 0.001). LAI significantly improved the continuation rate of treatment in the patient group belonging to cluster II. Furthermore, based on other factors and reasons for discontinuation, LAI should be preferably commenced in patients with a more stable condition.

Cerebrospinal fluid (CSF) production and absorption concept significantly changed in the early 2010s from "third circulation theory" and "classical bulk flow theory" to a whole new one as follows: First, CSF is mainly produced from interstitial fluid excreted from the brain parenchyma, and CSF produced from the choroid plexus plays an important role in maintaining brain homeostasis. Second, CSF is not absorbed in the venous sinus via the arachnoid granules, but mainly in the dural lymphatic vessels. Finally, the ventricles and subarachnoid spaces have several compensatory direct CSF pathways at the borders attached to the choroid plexus, e.g., the inferior choroidal point of the choroidal fissure, other than the foramina of Luschka and Magendie. In idiopathic normal pressure hydrocephalus (iNPH), the lateral ventricles and basal cistern are enlarged simultaneously due to the compensatory direct CSF pathways. The average total intracranial CSF volume increased from about 150 mL at 20 years to about 350 mL at 70 years due to the decrease in brain volume with aging and further increased above 400 mL in patients with iNPH. CSF movements are composed of a steady microflow produced by the rhythmic wavy movement of motile cilia on the ventricular surface and dynamic pulsatile flow produced by the brain and cerebral artery pulsation, respiration, and head movement. Pulsatile CSF movements might totally decrease with aging, but it in the ventricles might increase at the foramina of Magendie and Luschka dilation. Aging CSF dynamics are strongly associated with ventricular dilatation in iNPH.

Morphine, oxycodone, and fentanyl are commonly used to control cancer pain. Because these drugs have differences in receptor affinity or pharmacokinetic parameters, changing the opioid formulation may result in an unexpected outcome, depending on the patient’s condition. This study investigated whether low serum protein levels influence the effectiveness of opioid rotation by determining the impact of serum albumin levels on the analgesic effect before and after opioid rotation from morphine or oxycodone to fentanyl in cancer patients. The patients were classified into 3 groups according to their serum albumin levels before opioid rotation: group 1, <2.5 g/dL; group 2, from 2.5 g/dL to <3.0 g/dL; and group 3, ≥3.0 g/dL. There was no significant change in the percentage of patients with good pain control after rotation in group 1 or group 2; however, the percentage of patients with good pain control increased significantly in group 3. When the percentage of patients whose numerical rating scale scores increased, were unchanged, or decreased after rotation were compared, a significant difference in the percentage of those showing improvement was noted among the 3 groups and between groups 1 and 3. These findings suggest that monitoring serum albumin levels during fentanyl therapy is useful for pain management, and that the effectiveness of opioid rotation to fentanyl in patients with serum albumin levels of <2.5 g/dL should be carefully evaluated after rotation.
