Clostridium difficile (C. difficile) is one of the important pathogens which cause antibiotic-associated diarrhea (AAD) -diarrhea following antibiotic therapy. There are some reports of nosocomial outbreak of AAD caused by C. difficile.We analyzed risk factors and epidemiology of C. difficile-associated diarrhea (CAD) in Kumiai Hospital. From March 2003 to February 2004, 53 in patients developed AAD, of whom 35 patients (66%) were diagnosed as having CAD. Advanced age, bed-rest, tube-feeding, and prolonged administration of antibiotics were regarded as risk factors.In initial two months, seven cases developed CAD in one ward and five in another ward. After hand-washing and use of gloves were enforced in treating CAD patients, the incidence of CAD decreased. Epidemiological analysis was performed using PCR ribotyping of C. difficile strains recovered from 20 among 35 CAD cases in the different wards. Nineteen of 20 strains were identical, typed as the ribotype. These results may suggest nosocomial diarrhea but we cannot conclude that is a hospital infection as yet.Although all C. difficile strains recovered in this study were toxin A-positive, the result of the test using a toxin A detecting kit was negative in three cases. It is necessary toculture C. difficile in addition to detecting toxin A to diagnose CAD.

Ryoukeigomikanzoto is a Kampo formulation originally described in the text Kinkiyouryaku. This formulation has also been described as an indication for respiratory disease in some texts, because it was classified under respiratory diseases in the Kinkiyouryaku.
The authors, however, considered that indications for ryoukeigomikanzoto could be wider than previously thought. The composition of this formulation is very similar that of ryokeimikanto and ryokeijutsukanto. And we have prescribed ryokeigomikanzoto for patients with a reddish face and coldness of the legs, whose chief complaints were a reddish nose, coldness of the leg, dysuria, spioncerebellar degeneration and ringing of the ears. Moreover, we have obtained good results from the current trial. This report is intended to elucidate indications for this formulation by means of past clinical results and our own experience.

Previously, the authors reported that a painful point at the epigastrium may be closely related with the term “shinkashiketsu” for the Kampo formulation saikokeishito (SKT) which was described in the textbook, shoukanron. In order to find conclusive evidence for our hypothesis, we tried SKT in four patients, whose chief complaints were headache, epigastralgia with headache, irritable bowel syndrome, and anorexia due to Behcet's disease. In this trial, we obtained satisfactory clinical results, which strongly suggest that the symptom of a painful epigastral point correlates with the term shinkashiketsu in the shoukanron description.

Objective : Serum albumin is important marker in all aspects of stroke care including rehabilitation. We examined the serum albumin level of stroke patients, and investigated the relation between their serum albumin level and their prognosis. Methods : The serum albumin levels of 295 patients enrolled from 2008 to 2014 were sequentially checked in our hospital and in subsequent rehabilitation hospitals. Functional outcome was measured by functional independence measure (FIM) at the time of discharge from the rehabilitation hospital. Results : In all types (cerebral infarction, cerebral hemorrhage and subarachnoid hemorrhage (SAH)) of apoplexy, serum albumin levels were the highest at the time of admission, temporarily declined after admission, and almost recovered at the time of discharge. In SAH, the serum albumin levels deteriorated at a greater rate than in other types of stroke. In cerebral infarction and cerebral hemorrhage, the lowest serum albumin level was positively correlated with FIM at the time of discharge from the rehabilitation hospital (p<0.001). But, in SAH, there was no significant correlation between the lowest serum albumin level and FIM at the time of discharge (p=0.844). Conclusion : Our data suggest that serum albumin level is associated with the outcome of stroke patients, except for SAH patients. Serum albumin level should be one of the prognostic factors used in stroke patients, but we should consider that SAH patients are exceptional because of other neurological complications.

STUDY DESIGN: Retrospective study. PURPOSE: We experienced the situation wherein some patients had new-onset pain or dysesthesia around the ring and little fingers (C8 symptom) or ulnar aspect of the forearm (T1 symptom) after cervical laminoplasty (LP). We investigated the incidence and the cause of new C8 or T1 symptoms and the clinical outcomes after C3–C6 LP or C3–C7 LP. OVERVIEW OF LITERATURE: There were some reports regarding complications after cervical LP. However, there was no report regarding C8 or T1 symptoms after cervical LP. METHODS: Among the 33 patients enrolled in this study, 11 and 22 patients were treated with C3–C6 LP and C3–C7 LP, respectively. We prospectively evaluated C8 or T1 symptoms daily postoperatively for 1 week. The distance of the posterior spinal cord shifting and posterior subarachnoid space from C2 to T1 was measured by T2-weighted midsagittal magnetic resonance imaging (MRI). We evaluated pre- and postoperative axial neck pain, Japanese Orthopaedic Association (JOA) score, and JOA score improvement rate. RESULTS: C8 or T1 symptoms occurred in five and three patients with C3–C6 LP (45.5%) and C3–C7 LP (13.6%), respectively. The distance of the posterior subarachnoid space in C3–C6 LP at C7 was significantly shorter than that in C3–C7 LP at T1 on MRI 24 hours postoperatively (p=0.0448). Postoperative axial neck pain, pre- and postoperative JOA scores, and JOA score improvement rate were not significantly different. CONCLUSIONS: The incidence of C8 or T1 symptoms in C3–C6 LP was higher than that in C3–C7 LP. C8 or T1 symptoms would be caused by the posterior fila radicularia and spinal cord impingement on the intact lower end of the lamina.

OBJECTIVE: Palonosetron is effective for the management of acute and delayed chemotherapy-induced nausea and vomiting (CINV). While emetogenic carboplatin-based chemotherapy is widely used to treat gynecologic cancers, few studies have evaluated the antiemetic effectiveness of palonosetron in this setting. METHODS: A multicenter, single-arm, open-label phase II trial was conducted to evaluate the safety and effectiveness of palonosetron in controlling CINV in patients with gynecologic cancer. Chemotherapy-naïve patients received intravenous palonosetron (0.75 mg/body) and dexamethasone before the infusion of carboplatin-based chemotherapy on day 1. Dexamethasone was administered (orally or intravenously) on days 2–3. The incidence and severity of CINV were evaluated using the patient-completed Multinational Association of Supportive Care in Cancer Antiemesis Tool and treatment diaries. The primary endpoint was the proportion of patients experiencing complete control (CC) of vomiting, with “no rescue antiemetic medication” and “no clinically significant nausea” or “only mild nausea” in the delayed phase (24–120 hours post-chemotherapy). Secondary endpoints were the proportion of patients with a complete response (CR: “no vomiting” and “no rescue antiemetic medication”) in the acute (0–24 hours), delayed (24–120 hours), and overall (0–120 hours) phases, and CC in the acute and overall phases. RESULTS: Efficacy was assessable in 77 of 80 patients recruited. In the acute and delayed phases, the CR rates the primary endpoint, were 71.4% and 59.7% and the CC rates, the secondary endpoint, were 97.4% and 96.1%, respectively. CONCLUSION: While palonosetron effectively controls acute CINV, additional antiemetic management is warranted in the delayed phase after carboplatin-based chemotherapy in gynecologic cancer patients (Trial registry at UMIN Clinical Trials Registry, UMIN000012806).

Objective:
To evaluate the efficacy and safety of niraparib in Japanese women with heavily pretreated ovarian cancer.
Methods:
This Phase 2 open-label, single-arm study enrolled Japanese women with homologous recombination deficiency-positive relapsed, high-grade serous ovarian, fallopian tube, or primary peritoneal cancer who had completed 3–4 lines of therapy. The starting dose of niraparib was 300 mg administered once daily in continuous 28-day cycles until objective progressive disease, unacceptable toxicity, consent withdrawal or discontinuation. The primary endpoint, objective response rate (ORR), was assessed by the investigator using RECIST version 1.1. Safety evaluations included the incidence of treatment-emergent adverse events (TEAEs), including serious TEAEs.
Results:
Twenty women were enrolled and the confirmed ORR in the full analysis set (FAS) was 35.0% (7/20), consisting of 1 complete response and 6 partial responses. Disease control rate in the FAS was 90.0%. The most frequently reported TEAEs (>50%) were anemia, nausea, and platelet count decreased. One patient (5.0%) had TEAEs leading to discontinuation of niraparib whereas reductions or interruptions were reported in 14 (70.0%) and 15 (75.0%) patients, respectively. The median dose intensity (202.9 mg daily) corresponded to a relative dose intensity of 67.6%.
Conclusion
Efficacy and safety of niraparib in heavily pretreated Japanese women was comparable to that seen in an equivalent population of non-Japanese women. No new safety signals were identified.

BACKGROUND:
In health examinations for local inhabitants in cadmium-polluted areas, only healthy people are investigated, suggesting that patients with severe cadmium nephropathy or itai-itai disease may be overlooked. Therefore, we performed hospital-based screening to detect patients with cadmium nephropathy in two core medical institutes in cadmium-polluted areas in Akita prefecture, Japan.
METHODS:
Subjects for this screening were selected from patients aged 60 years or older with elevated serum creatinine levels and no definite renal diseases. We enrolled 35 subjects from a hospital in Odate city and 22 from a clinic in Kosaka town. Urinary ß-microglobulin and blood and urinary cadmium levels were measured.
RESULTS:
The criteria for renal tubular dysfunction and the over-accumulation of cadmium were set as a urinary ß-microglobulin level higher than 10,000 μg/g cr. and a blood cadmium level higher than 6 μg/L or urinary cadmium level higher than 10 μg/g cr., respectively. Subjects who fulfilled both criteria were diagnosed with cadmium nephropathy. Six out of 57 patients (10.5% of all subjects) had cadmium nephropathy.
CONCLUSIONS:
This hospital-based screening is a very effective strategy for detecting patients with cadmium nephropathy in cadmium-polluted areas, playing a complementary role in health examinations for local inhabitants.
