RESUMO
INTRODUCTION: Surgical site infection (SSI) is associated with increased morbidity and mortality rates, postoperative length of stay (pLOS), and medical costs. In colorectal surgery, cefmetazole (CMZ) and flomoxef (FMOX) are predominantly used in Japan, and they have almost the same spectrum of antibiotic activity against SSI pathogens, and an approximately four-fold cost difference (CMZ: â¼4$, FMOX: â¼16$). However, the difference between these antibiotics in SSI prophylaxis in colorectal surgery remains poorly understood. METHODS: We performed a single-center retrospective cohort study to investigate the prophylactic effects of these antibiotics, pLOS, and hospitalization costs. Patients who underwent elective colorectal surgery between April 2016 and March 2020 were considered for this study. RESULTS: Of the 634 patients, 316 (49.8%) were eligible. The SSI rates in the CMZ and FMOX groups were 14.7% and 12.5%, respectively. The incidence of organ/space SSI was approximately two-fold lower in the CMZ group than in the FMOX group (4.4% vs. 9.4%). Multivariable regression analysis revealed that CMZ was not significantly related to SSI, with an adjusted odds ratio of 1.21 (95% confidence interval [CI]: 0.52-2.82) and did not induce a significant difference in pLOS (difference ratio: 0.951 [95% CI: 0.868-1.041]). Hospitalization costs were reduced in the CMZ group (difference ratio, 0.951 [95% CI: 0.907-0.998], p = 0.042). The sensitivity analysis also showed results similar to the above findings. CONCLUSION: Our study showed that CMZ could be a cost-effective antibiotic with similar efficacy for SSI prophylaxis in colorectal surgery, compared with FMOX.

During the influenza season, most patients suspected of having influenza undergo rapid influenza diagnostic tests (RIDTs) in Japan despite their low sensitivity. However, the physician's actual rationale for prescribing antivirals, besides the results of RIDTs, remains poorly understood. Our study sought to identify the role of clinical information and physicians' experience in the initiation of anti-influenza agents. We retrospectively reviewed 380 patients who underwent RIDTs at the emergency department of our hospital from September 2018 to May 2019. Data regarding sex, age, etc., which could affect the decision of prescribing antivirals, were extracted from medical records. We performed logistic regression analysis to analyze the concurrent effect of potentially relevant clinical factors, results of RIDTs, and the physician's status on antiviral prescription. Multivariable analysis revealed that a positive RIDT had the largest effect on antiviral prescription, followed by physician status, high regional influenza activity, and patients' presentation within 12 h of symptom onset. Patient's age, comorbidities, and presentation after 48 h of symptom onset were not associated with antiviral treatment. Physicians with more years of experience were significantly more likely to prescribe antivirals for patients with low risk of complications. Our findings revealed the physicians' rationale for initiating antiviral treatment and the discrepancy with guideline indications of antivirals, which is the patient's age and comorbidities. Physicians, especially those with more than 3 years of experience, frequently prescribed antivirals for patients with low risk of complications; thus, educational interventions against this population could be useful to improve this situation.

Lupus aortitis is a rare and potentially life-threatening disorder. Previous studies have reported the utility of high-dose systemic glucocorticoids or surgery as the treatment, although there have been no related controlled trials. We herein report a 49-year-old woman with a 35-year history of systemic lupus erythematosus who was diagnosed with aortitis. Her symptoms and laboratory and imaging abnormalities rapidly resolved upon the administration of moderate-dose glucocorticoids. We subsequently performed a literature review of similar cases to identify the appropriate treatment and discuss these cases. A study of further cases will be needed to identify the characteristics of patients who would benefit from moderate-dose glucocorticoid therapy.

Community-acquired methicillin-resistant Staphylococcus aureus has been spreading worldwide, including in Japan. However, few cases of toxic shock syndrome caused by Community-acquired methicillin-resistant Staphylococcus aureus have been reported in Japan. We report 2 cases, in middle-aged women, of toxic shock syndrome due to Community-acquired methicillin-resistant Staphylococcus aureus via a vaginal portal of entry. The first patient had used a tampon and the second patient had vaginitis due to a cleft narrowing associated with vulvar lichen sclerosus. Both patients were admitted to our hospital with septic shock and severe acute kidney injury and subsequently recovered with appropriate antibiotic treatment. In our review of the literature, 8 cases of toxic shock syndrome caused by Community-acquired methicillin-resistant Staphylococcus aureus were reported in Japan. In these 8 cases, the main portals of entry were the skin and respiratory tract; however, the portal of entry of Community-acquired methicillin-resistant Staphylococcus aureus from a vaginal lesion has not been reported in Japan previously.
RESUMO
Herein we present two cases of hypereosinophilic syndrome with a unique clinical presentation. One patient showed severe systemic thrombosis with splenic rupture and the other patient showed finger gangrene with various systemic symptoms. Both patients were examined histologically, and several characteristics were noted. First, fresh or organized thrombosis with marked eosinophilic infiltration was observed in the cavity and walls of the thrombosed vessels. Second, many eosinophils showed degranulation and were positive for eosinophilic cationic protein on immunohistological examination. Third, the structures of thrombosed vessels were well preserved, which is not observed in systemic vasculitis. These patients exhibited no neoplastic features and were treated with prednisolone with excellent therapeutic results.

Prosthetic graft infection is difficult to diagnose early, and hence, is associated with high mortality and morbidity rates. A 63-year-old man who had undergone surgical prosthetic replacement for an inflammatory thoracic aortic aneurysm 10 months previously visited our emergency room, complaining of chills, shivering, frequent vomiting, and back pain. He was diagnosed with severe sepsis, and a blood culture detected Streptococcus anginosus and Prevotella oralis. Repeated contrast-enhanced computed tomography (CT) scans of his chest revealed ectopic gas around the graft, and esophagogastroduodenoscopy revealed esophageal perforations at several sites. We therefore diagnosed him with aortic prosthetic graft infection accompanied with esophagomediastinal fistulas. He received medical treatment and three operations and recovered from the infection. This is a rare case of aortic prosthetic graft infection accompanied with esophagomediastinal fistulas, and we conclude that repeated CT is useful for identifying the primary infection site and invasion route in patients with suspected aortic prosthetic graft infection.
RESUMO
Antiphospholipid antibodies (aPL) have been reported to occur in numerous viral infections. We report a 24-year-old Japanese woman, who developed multiple venous thrombosis associated with the elevation of anticardiolipin IgM after acute viral infection presenting a mononucleosis-like illness. Two months later, aPL and thromboses disappeared. In this case both parvovirus B19 and cytomegalovirus antibodies IgM were elevated, which indicated the possibility of cross-reaction.

This is the first report on effective leukocytapheresis (LCAP) in an acquired infliximab (IFM) resistant patient with rheumatoid arthritis (RA). A 44-year-old Japanese woman with RA was treated with prednisolone, cyclosporine A, and methotrexate, which failed to stabilize the disease. Infliximab was then administered and the disease activity was controlled on December 2003. However, RA became active again on June 2004 so that LCAP was administered weekly for 5 weeks. After the LCAP treatment, the ACR20% response was obtained again and IFM has regained its efficacy.

BACKGROUND: The extent of clinical exposure needed to ensure quality care has not been well determined during internal medicine training. We aimed to determine the association between clinical exposure (number of cases seen), self- reports of clinical competence, and type of institution (predictor variables) and quality of care (outcome variable) as measured by clinical vignettes. METHODS: Cross-sectional study using univariate and multivariate linear analyses in 11 teaching hospitals in Japan. Participants were physicians-in-training in internal medicine departments. Main outcome measure was standardized t-scores (quality of care) derived from responses to five clinical vignettes. RESULTS: Of the 375 eligible participants, 263 (70.1%) completed the vignettes. Most were in their first (57.8%) and second year (28.5%) of training; on average, the participants were 1.8 years (range = 1-8) after graduation. Two thirds of the participants (68.8%) worked in university-affiliated teaching hospitals. The median number of cases seen was 210 (range = 10-11400). Greater exposure to cases (p = 0.0005), higher self-reports of clinical competence (p = 0.0095), and type of institution (p < 0.0001) were significantly associated with higher quality of care, using a multivariate linear model and adjusting for the remaining factors. Quality of care rapidly increased for the first 100 to 200 cases seen and tapered thereafter. CONCLUSION: The amount of clinical exposure and levels of self-reports of clinical competence, not years after graduation, were positively associated with quality of care, adjusting for the remaining factors. The learning curve tapered after about 200 cases.

BACKGROUND: We report a case of invasive sinus aspergillosis that extended to the orbital cavity and cavernous sinus and was improved by treatment with micafungin and itraconazole. CASE REPORT: A 83-year-old woman was referred to our hospital because of headache and impaired of eye movement on the right side. Physical examination revealed impaired function of cranial nerves, II, II, IV, and VI on the right side. MRI showed evidence of inflammation of the right sphenoid sinus and ethmoidal sinus and an enhancing mass in the right cavernous sinus and orbit. Because a culture of a specimen from the right sphenoid sinus extracted during endoscopic sinus surgery, yielede Aspergillus fumigatus, a diagnosed of invasive sinus aspergillosis complicated by cavernous sinus symdrome and orbital apex symdrome was made. It was difficult to completely remove the mass in the sinuses surgically and drug therapy with micafungin was started and then itraconazole was added. The clinical manifestations and the impaired function of cranial nerves II, III, IV, and VI improved, and MRI showed regression of the mass in the sinuses temporary in response to drug therapy. CONCLUSION: Invasive sinus aspergillosis often progresses rapidly in the absence of surgery. Our case is valuable, because invasive sinus aspergillosis was improved by drug therapy alone, and combined treatment with micafungin and itraconazole was effective.

We report a case of bulla infection caused by Mycobacterium fortuitum. The patient was a 66 year-old female associated with interstitial pneumonitis. The chest X-ray film showed cavities with thick walls and niveau formation, which initially suggested pulmonary abscesses. The chest CT scan showed infiltrative shadows surrounding multiple bullae. Smears and cultures of the sputum were repeatedly positive for mycobacteria, which was identified to be M. fortuitum. By chemotherapy with imipenem/cilastatin sodium, clarithromycin, levofloxacin, and minocycline on the basis of susceptibility test, sputum converted to negative within 2 months, abnormal shadows on the roentgenogram and laboratory data showed improvement. There are no signs of recurrence after completion of the treatment for 12 months.

Abstract Thrombotic thrombocytopenic purpura (TTP) is an unusual complication of systemic lupus erythematosus (SLE). Although the reported association between SLE and TTP is increasing, a few cases do improve without plasmatherapy. We report a case of TTP which was successfully treated without plasmatherapy, which might be underestimated as an etiology of thrombocytopenia in SLE. TTP should always be considered as a concomitant disease when Coombs' negative hemolytic anemia or thrombocytopenia is seen in SLE patients.
