A complete loss of merosin, which is encoded by LAMA2, causes congenital muscular dystrophy with leukoencephalopathy. Partial merosin deficiency can be caused not only by primarily LAMA2 mutations, but also secondarily by dystroglycanopathy. Although it can be molecularly diagnosed based on a genetic analysis, this method is labor-intensive because of its huge genome size. A 26-year-old male patient presented with mild muscular weakness, joint contractures, and epilepsy. Double immunofluorescence staining of a muscle biopsy specimen showed mislocalization of merosin, and a genetic analysis revealed a homozygous c.818G>A (p.Arg273Lys) mutation in LAMA2. Double immunofluorescence staining and whole exome sequencing were useful for the diagnosis of partial merosin deficiency.

Ehlers-Danlos syndrome, hypermobility type (EDS-HT) is unexpectedly common and is associated with a high rate of gastrointestinal manifestations. We herein report the first documented case of mobile cecum associated with EDS-HT. A 21-year-old woman with repeated right lower abdominal pain was initially diagnosed with EDS-HT. Abdominal examinations performed in the supine position, such as CT and ultrasonography, showed no gross abnormalities. In contrast, oral barium gastrointestinal transit X-ray images obtained with changes in the patient's body position revealed position-dependent cecal volvulus with mobile cecum. She was finally discharged with a dramatic resolution of her symptoms after laparoscopic cecopexy for mobile cecum.

We herein report a woman in her 50s with systemic lupus erythematosus (SLE) who developed swelling and pain in her fingers; the symptoms were more prominent in winter. Magnetic resonance imaging (MRI) revealed bone edema in the phalanges of both hands, which was compatible with phalangeal microgeodic syndrome (PMS). This is the first reported case of PMS in a patient with SLE and suggests that performing MRI should be considered for patients with SLE in order to assess the nature of finger symptoms and signs more precisely.

The current standard diagnostic approach for progressive multifocal leukoencephalopathy (PML) is to perform a DNA test to identify the presence of the JC virus in cerebrospinal fluid (CSF). A 32-year-old woman with a 5-year history of systemic lupus erythematosus developed right hemiplegia and motor aphasia. MRI revealed a large white matter lesion in the left frontal lobe. JC virus DNA was undetectable in the CSF, but a brain biopsy showed typical histopathology and a high DNA load of the JC virus. The patient was treated with mefloquine and mirtazapine, and is currently alive at 24 months after onset. An early brain biopsy may therefore be important for making a timely diagnosis of PML.

Objective Periodontal disease may predispose individuals to cardiovascular disease (CVD). Diabetes mellitus, especially in patients with severe periodontitis, increases the risk of CVD mortality. However, the outcomes of periodontal therapy vary among the different treatment modalities. We aim to investigate whether periodontal treatment could influence the occurrence of CVD in patients with type 2 diabetes and periodontal problems. Methods A retrospective cohort study was conducted based on a dataset released by Taiwan National Health Insurance (NHI). The dataset was composed of randomly sampled, newly diagnosed diabetic patients who received insurance benefits from 1999 to 2001; patients who were younger than 18 years of age or who already had CVD before 1999 were excluded. The NHI code was used to identify the treatments, including subgingival curettage and flap operations. The patients' demographic variables were matched using a 1:4 propensity score. All of the subjects were followed up until the onset of CVD, or December 31, 2011. A Cox proportional hazards regression analysis was performed to evaluate the effects of periodontal treatment on the rates of myocardial infarction, heart failure and stroke. Results Three thousand thirty-nine and 12,156 diabetic subjects were classified into the advanced periodontal treatment group and the non-advanced periodontal treatment group, respectively. The Cox proportional hazards analysis revealed that although the overall incidence of CVD was not significantly improved (Hazard ratio, HR 0.95; 95% CI 0.90-1.01), advanced periodontal treatment reduced the rates of myocardial infarction (HR 0.92; 95% CI 0.85-0.99) and heart failure (HR 0.60; 95% CI 0.45-0.80). There was no significance difference in the incidence of stroke (HR 0.95; 95% CI 0.85-1.06). Conclusion Advanced periodontal therapy lowers the rate of CVD, especially myocardial infarction and heart failure. Dental management has a beneficial effect on the health of patients with type 2 diabetes.

A previously healthy 77-year-old Japanese man presented with a 2-week history of daily fevers peaking at 38°C, chills, hearing loss, and almost 10 kg of unintentional weight loss over 2 months. Pure tone audiometry showed mixed conductive-sensorineural hearing loss: right, 63.6 dB, left, 80.0 dB. Blood tests after admission showed a high myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA) level (>300 U/mL), so we suspected ANCA-related vasculitis. The Japanese Otorhinolaryngology Society has recently been advocating the concept of otitis media with ANCA-associated vasculitis (OMAAV). Our case met the criteria proposed, leading to our diagnosis.

Ceftriaxone is a widely used third-generation cephalosporin showing advantageous pharmacokinetic properties and a broad antimicrobial spectrum. We herein report a case of ceftriaxone-induced neurotoxicity in a 56-year-old man on hemodialysis. Seven days after initiating high-dose ceftriaxone, the patient developed impaired consciousness along with facial myoclonus and sporadic phonation. The symptoms clearly disappeared shortly after withdrawal of the drug. Ceftriaxone is considered a safe antibiotic for patients with renal insufficiency, since it is excreted via both haptic and renal pathways. Physicians should note that antibiotic-associated encephalopathy may develop in patients administered ceftriaxone, especially in those complicated with renal dysfunction.

We herein report an 87-year-old woman who was taking clonazepam at 1.5 mg/day. She was hospitalized with an old cerebral infarction complicated with symptomatic epilepsy, dementia, dyslipidemia, and chronic cholecystitis. Electrocardiogram revealed severe bradycardia at 31 beats/min. The bradycardia disappeared on day 3 after clonazepam withdrawal, although the serum clonazepam level had been within normal limits. She was diagnosed with clonazepam-associated bradycardia, which was likely related to the potential calcium channel-blocking properties of clonazepam. Because of age-related pharmacokinetic and pharmacodynamic changes, the adverse effects of clonazepam should be considered, especially in disabled elderly individuals with multiple comorbidities.

Thyroid storm is a life-threatening disorder that remains a therapeutic challenge. Although β-blockers are the mainstay for treatment, their use can be challenging in cases complicated by rapid atrial fibrillation and decompensated heart failure. We present a case of thyroid storm-associated atrial fibrillation and decompensated heart failure complicated by gastrointestinal dysfunction secondary to diffuse peritonitis that was successfully managed by a switching therapy, in which the continuous intravenous administration of landiolol was changed to bisoprolol via transdermal patch, in the acute phase treatment. This switching therapy may offer a promising therapeutic option for this potentially lethal disorder.

Objective Naratriptan has been reported to reduce the frequency of cluster headache. The purpose of this study was to determine whether naratriptan is effective as a prophylactic treatment for cluster headache in Japan. Methods We retrospectively reviewed all 43 patients with cluster headache who received preventive treatment with naratriptan from April 2009 to April 2015. The International Classification of Headache Disorders, 3rd Edition (beta version) (ICHD-3 beta) was used to diagnose cluster headache. This study was conducted at 3 centers (Department of Neurology, Saitama Medical University; Saitama Neuropsychiatric Institute; Saitama Medical University International Medical Center). Patients were recruited from these specialized headache outpatient centers. Naratriptan was taken before the patient went to bed. Results The study population included 30 men (69.8%) and 13 women (30.2%). Twenty-two cases received other preventive treatments (51.2%), while 21 cases only received naratriptan (48.8%). Among the 43 cases, 37 patients (86.0%) achieved an improvement of cluster headache on naratriptan. Conclusion Naratriptan has been suggested as a preventive medicine for cluster headache because of the longer the biological half-life in comparison to other triptans. The internal use of naratriptan 2 hours before attacks appears to achieve a good response in patients with cluster headache.

Objective We attempted to clarify the factors related to the aggravation of depression in patients with subacute myelo-optico-neuropathy (SMON) caused by clioquinol intoxication more than 35 years previously. Methods We investigated changes in the depressive mental states that occurred with aging in 19 Japanese SMON patients (mean age, 78.3 years; range, 66-89 years) according to their scores on the Japanese version of the Zung Self-rating Depression Scale (SDS), which were obtained 3-10 years previously and their current scores. The depressive state was further evaluated using simultaneous semi-structured interviews. Results The depressive mental states of 6 patients, whose current total SDS scores had increased by ≥10% in comparison to the previous score, were considered to have been aggravated with aging. The mean current total SDS score of these six patients was significantly higher than the mean score of the 13 patients whose conditions were not aggravated. Among the 20 SDS questionnaires, the patients whose conditions were aggravated showed significantly higher scores in diurnal variation, sleep disturbance and weight loss. The semi-structured interviews revealed that physical disabilities due to the sequelae of SMON, a lack of acceptance of SMON, and a decline in social activities were important factors in the aggravation of their depressive mental states with aging. Conclusion The maintenance of social activities with public support was important for coping among Japanese SMON patients with a depressive mental state, especially those who could not walk independently or who could not go outside freely without assistance.

Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease that favors the cerebrum and typically occurs in immunosuppressed patients. We herein report the case of a 66-year-old man with PML, idiopathic CD4+ T lymphocytopenia (ICL), and chronic renal failure. Cranial magnetic resonance imaging (MRI) showed a crescent-shaped lesion in the left cerebellum, brainstem, and middle cerebellar peduncle. Although the patient did not present with HIV infection, collagen diseases, or tumors, JC virus DNA was detected in the cerebrospinal fluid. Clinicians should consider PML and ICL in the differential diagnosis if the patient develops progressive ataxia and a crescent-shaped cerebellar lesion on MRI.

Objective We retrospectively compared the clinical efficacy and toxicity of rituximab (R)-THP-COP (pirarubicin, cyclophosphamide, vincristine, and prednisolone) with that of R-CHOP (rituximab, adriamicin, cyclophosphamide, vincristine, and prednisolone) in previously untreated old patients with diffuse large B-cell lymphoma (DLBCL). Patients and Methods Patients admitted to our institution between 2004 and 2013 were examined. The patients received either R (375 mg/m2, day 1)-THP-COP (pirarubicin 50 mg/m2 day 1, cyclophosphamide 750 mg/m2 day 1, vincristine 1.4 mg/m2 day 1, and prednisolone 100 mg day 1-5) or R-CHOP (adriamicin 50 mg/m2 day 1, cyclophosphamide 750 mg/m2 day 1, vincristine 1.4 mg/m2 day 1, and prednisolone 100 mg day 1-5). The doses of chemotherapeutic agents were adjusted depending on the patient's age and associated complications. The treatment was performed for 6 to 8 cycles. Results Among 74 patients with DLBCL (median 76, range 65-90 years; male 39, female 35), 29 received R-THP-COP, while 45 received R-CHOP. The overall response rates were 94.6% (complete response 86.4%, partial response 8.1%). The 2-year overall and progression-free survival rates were 77.6% and 68.5% for the R-THP-COP regimen and 79.2% and 78.9% for R-CHOP, respectively. No significant differences were found between these two regimens regarding the clinical efficacies. The most frequent adverse event was neutropenia (72.4% for the R-THP-COP regimen, 88.9% for the R-CHOP regimen). The cardiac function as evaluated by ejection fraction values was not impaired in either regimen. Conclusion R-THP-COP was effective and safe as an alternative to R-CHOP.

Objective The goal of this study was to clarify the clinical manifestation of hypercalcemia due to hypoadrenalism in hemodialysis (HD) patients. Methods We retrospectively analyzed the clinical characteristics of five HD patients who had presented with hypercalcemia due to adrenal insufficiency (age: 69±7 [58-75] years old, time on HD: 13±11 [2-32] years). We conducted corticotropin-releasing hormone (CRH) and adrenocorticotropic hormone (ACTH) stimulation tests. We also examined serum bone turnover markers before and after glucocorticoid replacement. Results All patients had critical illnesses at the onset of hypercalcemia. They had at least one symptom, such as eosinophilia, hypoglycemia, or fever. The prevalence of hypercalcemia due to adrenal insufficiency was 1.3% in maintenance HD patients on admission. The causes of adrenal insufficiency were isolated ACTH deficiency, pituitary apoplexy, pituitary atrophy, glucocorticoid withdrawal syndrome, and unilateral adrenalectomy. Serum calcium (Ca) levels corrected by serum albumin were maximally increased to 12.9 to 14.3 mg/dL in four anuric HD patients and mildly elevated to 10.4 mg/dL in a patient with residual diuresis. Their basal serum cortisol levels ranged from <1.0 to 15.4 μg/dL. Single CRH injections failed to increase serum cortisol in any of the patients. Glucocorticoid replacement acutely normalized serum Ca and decreased levels of carboxy-terminal telopeptide of type I collagen, a marker of bone resorption. Conclusion Adrenal insufficiency could therefore be an occult cause of hypercalcemia in anuric HD patients who are critically ill.

Objective Superior mesenteric artery (SMA) syndrome is characterized by the compression of the third segment of the duodenum between the SMA and aorta, resulting in duodenal obstruction. Because the symptoms of the syndrome are similar to those of functional dyspepsia (FD), this study aimed to examine whether or not patients with SMA syndrome were present among those diagnosed with FD. Methods Patients with an FD diagnosis underwent measurement of the angle and distance between the SMA and aorta by ultrasonography or computed tomography. Patients with an angle of ≤22° or with a distance of ≤8 mm between the SMA and aorta were diagnosed with SMA syndrome. Bacterial culture of the duodenal aspirate was also performed. Results Of the 46 FD patients, 5 (11%) met the criteria. All 5 were women with a body mass index significantly lower than the remaining 41 patients (18.7 vs. 24.0 kg/m2, p=0.003). In addition, all 5 patients had 105/mL or more bacteria in the duodenum. The symptoms of these five patients were treated through dietary and postprandial posture counselling with or without medication. Conclusion Patients with SMA syndrome were observed among underweight women diagnosed with FD. Their symptoms may be associated with bacterial overgrowth.

Objective The predictors of in-hospital outcomes after primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) complicated with heart failure or cardiogenic shock at presentation remain unclear. Methods Using the AMI-Kyoto Multi-Center Risk Study database, the clinical background characteristics, angiographic findings, primary PCI results, and in-hospital prognoses were retrospectively compared between primary PCI-treated AMI patients with a Killip class status of ≥2 (Killip 2-4 patients, n=390) and those with a Killip class 1 status (Killip 1 patients, n=1,057). Results The Killip 2-4 patients were more likely to have a higher age and proportion of women and exhibited a higher prevalence of previous myocardial infarction, diabetes mellitus and chronic kidney disease or anemia on admission, lower systolic blood pressure (SBP) values on admission, a higher rate of multivessels or left main trunk as the culprit artery, a larger number of diseased vessels, a lower Thrombolysis In Myocardial Infarction (TIMI) grade in the infarct-related artery (IRA) before/after primary PCI and a significantly higher in-hospital mortality rate than the Killip 1 patients. According to a multivariate analysis, age was found to be an independent positive predictor of in-hospital mortality, while admission SBP was an independent positive predictor of in-hospital survival in both groups. In contrast, anemia on admission was found to be an independent predictor of in-hospital death, while the TIMI 3 flow in the IRA after PCI was found to be an independent factor for survival in the Killip 2-4 patients, but not the Killip 1 patients. Conclusion Anemia on admission and the final TIMI 3 flow in the IRA are critical determinants of in-hospital death in AMI patients with a Killip class status of ≥2 undergoing primary PCI.

Yellow nail syndrome (YNS) is characterized by yellowish nails, lymphedema, sinusitis, and pulmonary involvement and can be triggered by various underlying conditions, such as sinusitis or titanium exposure from an artificial joint or dental implant. Since YNS is potentially treatable, its timely diagnosis is important. The authors recently experienced a case of YNS in a patient who developed sinusitis, yellowish nails, bilateral edema of the extremities, and subclinical rheumatoid arthritis after the implantation of a cardiac pacemaker made from titanium. This case may be the first report of YNS induced by a titanium cardiac pacemaker.
