Prematurely born infants face unique risks, and the treatment of imminent preterm birth is thus an important part of perinatal care. Ritodrine hydrochloride (Rito) is widely used as a therapeutic agent to treat imminent preterm birth in Japan. Following assessment of the risks and benefits of short-acting β-agonists, including Rito, in Europe, however, the use of Rito has begun to be questioned. Thus, in this study we investigated the safety of Rito in the treatment of imminent preterm birth, with a particular focus on the adverse effects (AEs) on fetuses and newborn infants. Using the Pharmaceuticals and Medical Devices Agency of Japan's Japanese Adverse Drug Event Report (JADER) database, the AEs on fetuses and newborns caused by oral and injected Rito were extracted and analyzed. The reported odds ratios for oral Rito were significantly higher for fetal tachycardia, fetal bradycardia, neonatal hypoglycemia, and neonatal heart failure than for other drugs. The reported odds ratios for Rito injection were significantly higher for fetal tachycardia and neonatal hypoglycemia than for other drugs. Oral drugs had more adverse effect reports than injectable drugs.Lymph node tuberculosis is one of the most common forms of extrapulmonary tuberculosis worldwide. The study aimed to evaluate the role of positron emission tomography-computed tomography (PET-CT) in determining post-treatment response in lymph node tuberculosis. A PET-CT was done in all treatment naïve tubercular lymphadenitis adults at baseline and after six months of therapy. The post-treatment clinical response was compared with the metabolic response on PET-CT. Of the 25 patients with tubercular lymphadenitis, 9/25 patients showed a complete metabolic response (CMR) at six months, while 16 patients had a partial metabolic response (PMR). All patients with CMR had a good clinical response. However, discordance between clinical and PET findings was noticed in those with PMR. The role of PET-CT in evaluating post-treatment response in patients with tubercular lymphadenitis needs further evaluation with a larger sample size.A 54-year-old man suddenly developed impaired consciousness and left hemiplegia due to a right thalamic hematoma. Emergent ventricular drainage for acute hydrocephalus improved the level of consciousness, but macrosquare-wave jerks (MSWJ) consisting of a right-ward intrusive saccade and corrective saccade appeared. The MSWJ disappeared on day 2 when follow-up CT revealed improvement of hydrocephalus. However, on day 36, after ventricular drainage was clamped, the MSWJ reappeared. After ventriculoperitoneal shunt, MSWJ again subsided. In this patient, hydrocephalus may have stretched the superior colliculus, thereby decreasing activity of the fixation neurons and then omnipause neurons, and eventually resulting in the reversible MSWJ.A 74-year-old woman with a cyst in her pancreatic tail was referred to our hospital. Computed tomography confirmed a large cystic lesion with irregular wall thickening, abdominal lymph node swelling, and ascites. We diagnosed her with an unresectable mucinous cystic neoplasm, since ascites cytology revealed adenocarcinoma. The patient received chemotherapy up to the fifth line for 55.2 months. Gemcitabine plus nab-paclitaxel and modified FOLFORINOX achieved a partial response with a progression-free survival time of 12.1 and 20.4 months, respectively. The overall survival time from the beginning of first-line chemotherapy was 69.4 months.A 45-year-old man with allergic bronchopulmonary aspergillosis (ABPA) was treated with oral prednisolone (PSL) (30 mg/day), inhaled corticosteroids, and long-acting beta2-agonists. After confirmation of a PSL-dependent status (8 mg/day), subcutaneous injection with anti-interleukin (IL)-5 antibody (mepolizumab, 100 mg/month) was performed, and the PSL dose was tapered to 5 mg/day. However, ABPA recurred and proved refractory to oral itraconazole (200 mg/day). Alternative subcutaneous injection therapy with dupilumab (induction dose of 600 mg followed by a maintenance dose of 300 mg/2 weeks) enabled the successful withdrawal of oral PSL without clinical deterioration. This case demonstrates the potential utility of dupilumab for steroid-dependent ABPA via the synergistic suppression of IL-4 and IL-13 compared to monotherapy with anti-IL-5 antibody.Probst bundles are selectively seen in patients with agenesis of the corpus callosum (CC) and are thought to be homologous to the CC. We herein report a 19-year-old woman with partial agenesis of the CC. She developed acute encephalopathy during Bordetella pertussis infection. Brain magnetic resonance imaging (MRI) showed restricted diffusion of bilateral Probst bundles. She was treated with anti-epileptics and azithromycin and recovered with no neurological sequelae. Follow-up MRI showed the resolution of the diffusion abnormality. The characteristics of diffusion-weighted images on brain MRI and clinical course mimicked those in cases of clinically mild encephalopathy/encephalitis with reversible splenial lesion.A 60-year-old man presented to the emergency department with lightheadedness. He had severe hyponatremia (109 mEq/L) complicated by acute kidney injury (AKI) (serum creatinine 9.08 mg/dL). Because he was somnolescent, his hyponatremia was initially treated by administering a 130-mL bolus of 3% saline 2 to 5 times per day for 5 days. He subsequently underwent intermittent hemodialysis without any neurological problems. Previous reports have described patients with hyponatremia and AKI being treated with continuous renal replacement therapy. However, our strategy might be a feasible, low-cost treatment strategy of treating patients with hyponatremia and AKI who do not require immediate hemodialysis.We herein report a case of seronegative immune-mediated necrotizing myopathy (IMNM) concurrent with anti-Kv1.4 and anti-titin antibodies. A 72-year-old Japanese woman presented with a 29-year history of fluctuating high serum creatine kinase (CK) levels followed by intermittent ptosis and respiratory muscle weakness. https://www.selleckchem.com/products/ferrostatin-1.html This case highlights the fact that marked respiratory muscle weakness requiring intubation can be seen in an ambulant patient with IMNM. Marked respiratory muscle weakness, rhabdomyolysis-like acute elevation of CK levels, and anti-striational muscle antibodies may be a characteristic constellation of findings in a distinct subgroup of patients with inflammatory myopathy with myasthenia gravis or similar symptoms.We herein report the case of a 20-year-old man with a history of epilepsy who presented with frequent transient loss of consciousness (T-LOC) and polymorphic ventricular tachycardia (VT) with QT interval prolongation. Blood investigations revealed panhypopituitarism. Following a biopsy, he was diagnosed with brain germinoma. During the biopsy, he had an episode of polymorphous VT with QT prolongation. There was no recurrence of T-LOC following chemotherapy and hormone replacement therapy. This case indicates the importance of checking the QT interval in patients with T-LOC, including those with seizures and brain tumors, to ensure appropriate treatment.Leukoencephalopathy with high-intensity signals in the corticomedullary junction on diffusion-weighted imaging (DWI) is a diagnostic hallmark for neuronal intranuclear inclusion disease (NIID). link2 We herein report a 65-year-old man who developed dementia and was diagnosed with NIID 2 years later. Of note, he had coincidentally undergone brain magnetic resonance imaging 14 and 10 years before the onset of dementia. No abnormalities were discerned on DWI on either of these occasions, but high-intensity signals in the corticomedullary junction on DWI were revealed two years before the clinical onset. The early recognition of this pathognomonic white matter change may facilitate the presymptomatic diagnosis of NIID.Fusobacterium necrophorum is a very rare cause of endocarditis. We herein report a case of F. necrophorum endocarditis with liver abscesses in a 51-year-old woman. This is the first reported case of monomicrobial F. necrophorum endocarditis to present in a patient over 50 years old. We also reviewed 10 reported cases, including the present case. Our review indicated that anaerobic bacteria, including Gram-negative anaerobic bacilli such as F. necrophorum, should be considered in the differential diagnosis of infective endocarditis, especially in patients without preexisting organic heart disease.Isodehydrodigallic acid, which is an important component of several ellagitannin compounds, was easily synthesized using a classical Ullmann condensation reaction.Alkaline hydrolysis of crude resin glycoside fraction of the seeds of Ipomoea muricata (L.) Jacq. (Convolvulaceae) yielded a new glycosidic acid, muricatic acid D; three known glycosidic acids, namely, muricatic acids A, B, and C; and three known organic acids, namely, isobutyric, 2S-methylbutyric, and 2S-methyl-3S-hydroxybutyric acid. Two new genuine resin glycosides with macrolactone structures (jalapins), muricatins X and XI, were also isolated from the fraction. Their structures were determined using spectroscopic data and chemical evidence.Monitoring analysis of 14 per- and polyfluoroalkyl substances (PFAS), 9-chlorohexadecafluoro-3-oxanonane-1-sulfonate (F-53B) and dodecafluoro-3H-4,8-dioxanonanoate (ADONA) in bottled drinking water, tea and juice samples was performed using LC coupled with tandem mass spectrometry (LC-MS/MS) and solid-phase extraction (SPE). In the electrospray negative ion mode, the limit of detection and limit of quantification (LOQ) values were 0.1 to 0.8 ng/mL and 0.2 to 1.6 ng/mL, respectively. The calibration curves were linear from LOQ to 50 ng/mL (r2 > 0.999). The SPE procedure (Presep PFC-II) was utilized for sample preparation and recovery rates for three standards (35, 70 and 140 ng/L) were 80.4-118.8% with relative standard deviation (RSD) ≤ 0.6%. Using the developed method, various samples (n = 54) from Japanese markets were investigated for PFAS and F-53B contamination, and values below the LOQ were observed. It is concluded that for monitoring products in the Japanese market, our method represents a significant improvement over complex techniques for the quantification of PFAS and related compounds from various foods.The first concise total syntheses of O-3'-senecioyl α-bisabolol β-D-fucopyranoside (4a) and O-3'-isovaleroyl α-bisabolol β-D-fucopyranoside (4b) were achieved through final-stage site-selective acylation via the activation of cis-vicinal diols by imidazole-containing boronic acid catalysts as a key step. link3 This synthetic method was also effective for the syntheses of unnatural analogues with modified acyl side chains or carbohydrate moiety.We disclose our studies on a copper-mediated reaction of alkynes with trimethylsilyl azide to afford nitriles, and proposed a reaction mechanism, which involves an iodoalkyne and an iodotriazole as intermediates.Vibrational spectroscopic imaging has become useful analytical tools for quality control of drug products. In this study, we applied microscopic attenuated total reflection (ATR)-IR and confocal Raman microscopy to elucidate microscopic structure of creams and for the formulation design in the development of semi-solid drug products. The model creams were prepared with prednisolone (PRD) and fluconazole (FLC) as active pharmaceutical ingredients and oily solvents such as mineral oil (MO), isopropyl myristate (IPM), benzyl alcohol (BA) and diethyl sebacate (DES). As a result of microscopic ATR-IR imaging, several domains indicating oily internal phase were observed, which had absorption around 1732 and 1734 cm-1 derived from MO, IPM and DES. In addition, domains of BA around 1009 cm-1 were observed at the complemental or similar position in the formulation with MO or DES, respectively. These results suggested that the creams were oil-in-water type and the distribution of domains would reflect the compatibility of the solvents.
