Background: Necrotising fasciitis (NF) is a life-threatening soft-tissue infection that rapidly destroys the epidermis, subcutaneous tissue, and fascia. Despite their low virulence, Lactobacillus spp. can cause NF, and because of its rare incidence, there is limited information about its molecular and clinicopathological characteristics. We report a rare case of NF in a patient with type 2 diabetes mellitus diagnosed on admission and severe obesity due to infection with two types of Lactobacillus spp. that manifested in extensive necrosis., Case Presentation: A 48-year-old woman was referred to our hospital with a complaint of difficulty walking due to severe bilateral thigh pain. She presented with mild erythema, swelling, and severe skin pain extending from the pubic region to the groin. The patient was morbidly obese, had renal dysfunction, and had diabetes mellitus diagnosed on admission.; her LRINEC (Laboratory Risk Indicator for Necrotising Fasciitis) score was 9, indicating a high risk of NF. An exploratory surgical incision was made, and NF was diagnosed based on fascial necrosis. Emergent surgical debridement was performed, and cultures of the tissue culture and aspirated fluid/pus revealed two types of Lactobacillus spp.: Lactobacillus salivarius and L. iners. The patient was admitted to the intensive care unit (ICU), where antibiotics were administered and respiratory and circulatory management was performed. Diabetic ketoacidosis was detected, which was treated by controlling the blood glucose level stringently via intravenous insulin infusion. The patient underwent a second debridement on day 11 and a skin suture and skin grafting on day 36. The patient progressed well, was transferred from the ICU to the general ward on day 41, and was discharged unassisted on day 73., Conclusions: Lactobacillus spp. are rarely pathogenic to healthy individuals and can scarcely trigger NF. However, these bacteria can cause rare infections such as NF in immunocompromised individuals, such as those with diabetes and obesity, and an early diagnosis of NF is imperative; surgical intervention may be required for the prevention of extensive necrosis. The LRINEC score may be useful for the early diagnosis of NF, even for less pathogenic bacteria such as Lactobacillus., (© 2024. The Author(s).)

We developed a system that transfers images via network and started using them in our hospital's PACS (Picture Archiving and Communication Systems) in 2006. We are pleased to report that the system has been re-developed and has been running so that there will be a regional liaison in the future. It has become possible to automatically transfer images simply by selecting the destination hospital that is registered in advance at the relay server. The gateway of this system can send images to a multi-center, relay management server, which receives the images and resends them. This system has the potential to be useful for image exchange, and to serve as a regional medical liaison.

We evaluated the advantages and disadvantages of Huber Plus through three outpatients treated with central venous (CV) port chemotherapy (FOLFOX). One of the three outpatients first received chemotherapy with safety huber (Huber Plus) in this study, and the huber needle was changed from non-safety to a safety huber (Huber Plus) in two of the three outpatients. All three outpatients were taught about needle removal methods and port care. In patients? education, 1) we used a skin model and training CV port, and 2) dressing materials were used as film dressing plus three-point fixation by Fixomull stretch. As a result, the safety system assured zero incidents. Moreover, the evaluation revealed that operability and pain of Huber Plus were not clinical problems. We suggest that Huber Plus is applicable in outpatient chemotherapy and that our care plan with patients? education might become a standard treatment.

We conducted a pilot trial to compare the operability and safety of two huber needles in the infusion center. In the present study, we used huber needles without the safety cover and one huber needle with the safety cover (Huber Plus(R)). Both huber needles were used nine times. The successful puncture rate of the first time puncture and the incidence of needle accidents with both huber needles were 100% and 0%, respectively. The evaluation of pain and uneasiness by VAS (Visual Analogue scale)revealed the superiority of the safety needle over the than non-safety needle(pain: 3.8 vs 2.6, uneasiness: 3.7 vs 0.5). To our knowledge, this is the first report of the safety of the huber needle in Japan. This system may be recommended in Japan to avoid needle stick injuries, patient pain and uneasiness.

Purpose: An incident situation of hepatic arterial infusion (HAI) chemotherapy was investigated, and the improvement methods were evaluated., Methods: As a result of surveillance, all incidents were observed in patients during five day continuous HAI infusion conditions: 1) Reverse-flow hemorrhage occurred at home by disconnection of the catheter; and 2) hemorrhage by natural withdrawal of the huber needle, were diagnosed. For 1) we further taped the catheter connection area by Tegaderm and changed the dressing material from SILKYPORE DRESSING (10 x 13 cm and 4 x 6.5 cm in absorption part) plus two-person fixation by Fixomull stretch to IV3000 (9 x 12 cm non-absorption part) plus three-person fixation by Fixomull stretch. Moreover, we changed the needle type (subcutaneous adiposus thickness) from 22 G x 3/4 inch to 20 G x 1 inch., Results and Conclusions: The incidents were not observed in 72 patients treated with HAI after improvement. We suggest that prevention of hemorrhage by further taping the catheter connection and improved stability of the needle by dressing proved effective. In conclusion, HAI incident surveillance may well be an important way to care for outpatients treated with HAI chemotherapy, and we thus intend to continue the HAI incident surveillance to improve the nursing care.

We examined four problems of the ordering system type infusion center. In this system,regimen is made by chief physician and cared by the staff in the infusion center. 1) In securing of the staff, an upbringing of doctors and IV nurses are important. 2) An evidence-based regimen is necessary in order to minimize the differences of regimen made by each doctor. 3) A facility expansion might reduce an incident risk. 4) As the condition of patient suddenly changes,the chief physician of the patient should be contacted. We suggest that it is particularly important to make these problems clarified and solved by the team within the institution.

Background: Syndrome X has been recognized as a disease that is primarily reflected in the cardiac microvasculature. Myocardial metabolism in this condition has been studied, but not in relation to small vessel pathology., Methods and Results: In order to examine the relationship between myocardial metabolism and small vessel pathology, 24 consecutive patients with syndrome X (7 men, 17 women; mean age 58 years) were evaluated by the thallium exercise stress test, positron emission tomography using F-18 fluoro-deoxyglucose (FDG), and an endomyocardial biopsy. All patients showed either diffuse or focal increase in the myocardial uptake of FDG, but only 17 patients (71%) showed hypoperfused areas with partial or complete redistribution in the thallium study. Quantification of myocardial FDG uptake revealed that the value in syndrome X patients was 10-fold higher than in controls (p<0.0001). Histopathological examination revealed that in syndrome X there is an extensive increase in smooth muscle cells and thickening of the vascular wall, even in capillary vessels, and the small vessel lumen was markedly narrowed. There was a significant inverse correlation between FDG myocardial uptake and the microvessel luminal area., Conclusions: In syndrome X patients, myocardial FDG uptake is increased extensively, which is strongly associated with narrowed myocardial microvasculature.
