Central diabetes insipidus (CDI), which is characterized by polyuria and polydipsia, is caused by a deficiency of the antidiuretic hormone arginine vasopressin (AVP). While CDI is treated with desmopressin, an analogue of AVP, the intranasal formulation is inconvenient and CDI patients reportedly prefer the oral formulation to the intranasal one. In Japan, intranasal desmopressin had been the o...

This study examined the role of intranasal vaccination with Mycobacterium tuberculosis antigen85 complex proteins formulated in dimethyldioctadecylammonium bromide against airway Mycobacterium tuberculosis challenge in mice. Intranasal vaccination with antigen85A and antigen85B induced a significantly higher level of interferon-gamma, interleukin-12 and interleukin-4 in cervical lymph nodes tog...

OBJECTIVES/HYPOTHESIS It is theorized that intranasal cavity volumes change throughout the aging process, possibly secondary to hormonal changes and atrophy of the sinonasal mucosa. Our objective is to compare intranasal volumes from different age groups to test the hypothesis that intranasal cavity volume increases with age. STUDY DESIGN Case series. METHODS An analysis of computed tomogra...

BACKGROUND Treating pain associated with acute coccyx fractures can be challenging. Intranasal calcitonin has been used to treat acute pain after vertebral fracture, and may even accelerate fracture healing. However, intranasal calcitonin has never previously been published as part of the treatment of acute coccyx fractures. OBJECTIVE To examine a series of cases in which intranasal calcitoni...

Background: The risk of anesthesia increases with age, so it is necessary to choose a safe and effective method. In this study, we compared the effectiveness of intranasal fentanyl with intravenous fentanyl in patients undergoing cataract surgery. Methods: This study was a triple-blind prospective randomized clinical trial (The patient, physician, and data analyzer were unaware of the patient ...

Deferoxamine (DFO) is a high-affinity iron chelator approved by the Food and Drug Administration for treating iron overload. Preclinical research suggests that systemically administered DFO prevents and treats ischemic stroke damage and intracerebral hemorrhage. However, translation into human trials has been limited, probably because of difficulties with DFO administration. A noninvasive metho...

Intranasal transmission of hepatitis C virus (HCV) via contaminated drug-sniffing implements is a potential but unconfirmed source of viral infection. We demonstrate the virological plausibility of intranasal transmission by confirming that blood and HCV RNA are present in the nasal secretions and drug-sniffing implements of HCV-infected intranasal drug users recruited from a community health c...
