Serotype distribution among adults with community-acquired pneumococcal pneumonia in Japan between 2019 and 2022: A multicenter observational study.

is a leading cause of community-acquired pneumonia (CAP) in adults. With the introduction of pneumococcal conjugate vaccines (PCVs) into pediatric national immunization programs, the serotype distribution of pneumococcal disease among adults has changed due to indirect effect. In Japan, PCV15 and PCV20 have been introduced, and PCV21 is under review for approval in adults.

Unicentric Castleman's Disease of Paraspinal Origin Requiring Differentiation From Schwannoma: Case Report.

Unicentric Castleman's disease (UCD) typically presents as an asymptomatic tumour in the anterior or middle mediastinum. Occurrence in the paravertebral region is comparatively rare and it requires differentiation from neurogenic tumours by imaging. In our patient, preoperative imaging findings were atypical of schwannoma.

Longitudinal course and outcome of social jetlag in adolescents: A 1-year follow-up study of the adolescent sleep health epidemiological cohorts.

The discrepancy in sleep timing between weekdays and weekends - social jetlag (SJL) - is known to negatively affect student quality of life (QOL). However, the association between social jetlag and physical/mental QOL among adolescents and the precise effect of social jetlag on depressive symptoms and daytime sleepiness remains unknown. This study investigated the longitudinal course, risk factors, and effects of social jetlag, a circadian misalignment, in a school-based cohort.

Specific antibody deficiency to pneumococcal polysaccharide in a young adult with recurrent respiratory infections: a case report.

Specific antibody deficiency against pneumococcal serotypes was detected in a patient with recurrent episodes of fever. A 21-year-old man presented with a two-month history of recurrent episodes of fever and shaking chills. He was diagnosed with recurrent episodes of pneumonia caused by Streptococcus pneumoniae serotype 19A and treated with amoxicillin.

Analysis of nocturnal desaturation waveforms using algorithms in patients with idiopathic pulmonary fibrosis.

Purpose: Sleep-disordered breathing is recognized as a comorbidity in patients with idiopathic pulmonary fibrosis (IPF). Among them, nocturnal hypoxemia has been reported to be associated with poor prognosis and disease progression. We developed a diagnostic algorithm to classify nocturnal desaturation from percutaneous oxygen saturation (SpO) waveform patterns: sustained pattern, periodic pattern, and intermittent pattern.

Dark Rearing Promotes the Recovery of Visual Cortical Responses but Not the Morphology of Geniculocortical Axons in Amblyopic Cat.

Monocular deprivation (MD) of vision during early postnatal life induces amblyopia, and most neurons in the primary visual cortex lose their responses to the closed eye. Anatomically, the somata of neurons in the closed-eye recipient layer of the lateral geniculate nucleus (LGN) shrink and their axons projecting to the visual cortex retract. Although it has been difficult to restore visual acuity after maturation, recent studies in rodents and cats showed that a period of exposure to complete darkness could promote recovery from amblyopia induced by prior MD.

Primary pleural synovial sarcoma with repeated resection leading to long-term survival.

Primary pleural synovial sarcoma is a malignant tumour and thought to be more aggressive than synovial sarcoma which occurs in extremities. Its treatment strategy has not been fully established because of its rarity. We report a primary pleural synovial sarcoma case which achieved a long-term survival with repeated surgery of recurrent pleural tumour.

Endobronchial metastases 20 years after prostate cancer excision.

A 78-year-old Japanese man who had undergone total prostatectomy for prostate cancer (pT3cN1M0, Gleason score 3 + 3) 20 years previously was referred to the Respiratory Medicine Department of our institution because of a 1-week history of chest pain and cough. Computed tomography showed multiple small nodules and mediastinal lymph node enlargement. Bronchoscopy revealed multiple soft polypoid masses and obstruction of the lingular segment.

Nivolumab-induced acute-onset type 1 diabetes mellitus as an immune-related adverse event: A case report.

A 60-year-old Japanese man, with no medical or family history of diabetes, presented with acute-onset type 1 diabetes following nivolumab treatment for advanced non-small-cell lung cancer. During cycle 35 of nivolumab therapy, his glycated hemoglobin level increased from 7.6% to 9.

[Severe Japanese Spotted Fever Complicated by Acute Respiratory Failure in Kobe City].

We report herein on a case of severe Japanese spotted fever complicated by acute respiratory failure in Kobe City. A 70-year-old female presenting with general malaise and systematic erythema was admitted to our hospital in June, 2013. From her history and physical examination, she was found to be suffering from scleroderma and mild interstitial pneumonia.

Effect of a family psychoeducational program on relatives of schizophrenia patients.

Aims: Family psychoeducational programs have been shown to be effective in terms of knowledge acquirement and relapse prevention, but few studies have looked at whether one mode of educational method is more effective than another. The aim of the present study was to compare several modes of educational approaches and to elucidate which mode of education is more effective.

Methods: A total of 110 relatives of 95 patients with schizophrenia received three types of family psychoeducational programs between January 1995 and September 2003: a small group with two sessions (P1), a large group with nine sessions (P2), and a large group with five sessions (P3).

Primary breast mucosa-associated lymphoid tissue (MALT) lymphoma with high-grade transformation evidenced by prominent lymphoepithelial lesions.

Primary breast lymphoma, particularly primary mucosa-associated lymphoid tissue (MALT) lymphoma, is a rare disease. We report here a case of a MALT lymphoma of the breast with high-grade transformation. An 84-year-old woman presented with a Pagetoid mass in her right breast.
