RESUMO
OBJECTIVES: The artificial intelligence competition in healthcare at TEKNOFEST-2022 provided a platform to address the complex multi-class classification challenge of abdominal emergencies using computer vision techniques. This manuscript aimed to comprehensively present the methodologies for data preparation, annotation procedures, and rigorous evaluation metrics. Moreover, it was conducted to introduce a meticulously curated abdominal emergencies data set to the researchers. METHODS: The data set underwent a comprehensive central screening procedure employing diverse algorithms extracted from the e-Nabiz (Pulse) and National Teleradiology System of the Republic of Türkiye, Ministry of Health. Full anonymization of the data set was conducted. Subsequently, the data set was annotated by a group of ten experienced radiologists. The evaluation process was executed by calculating F1 scores, which were derived from the intersection over union values between the predicted bounding boxes and the corresponding ground truth (GT) bounding boxes. The establishment of baseline performance metrics involved computing the average of the highest five F1 scores. RESULTS: Observations indicated a progressive decline in F1 scores as the threshold value increased. Furthermore, it could be deduced that class 6 (abdominal aortic aneurysm/dissection) was relatively straightforward to detect compared to other classes, with class 5 (acute diverticulitis) presenting the most formidable challenge. It is noteworthy, however, that if all achieved outcomes for all classes were considered with a threshold of 0.5, the data set's complexity and associated challenges became pronounced. CONCLUSION: This data set's significance lies in its pioneering provision of labels and GT-boxes for six classes, fostering opportunities for researchers. CLINICAL RELEVANCE STATEMENT: The prompt identification and timely intervention in cases of emergent medical conditions hold paramount significance. The handling of patients' care can be augmented, while the potential for errors is minimized, particularly amidst high caseload scenarios, through the application of AI. KEY POINTS: ⢠The data set used in artificial intelligence competition in healthcare (TEKNOFEST-2022) provides a 6-class data set of abdominal CT images consisting of a great variety of abdominal emergencies. ⢠This data set is compiled from the National Teleradiology System data repository of emergency radiology departments of 459 hospitals. ⢠Radiological data on abdominal emergencies is scarce in literature and this annotated competition data set can be a valuable resource for further studies and new AI models.

Diabetes is one of the most common health problems worldwide. Diabetic foot wounds (DFWs) are hazardous complications of the disease. Patients are often referred to rehabilitation facilities at later stages of the diabetic complications, particularly after amputation surgery. There are potential benefits of rehabilitation practices in preventing and managing DFWs. Therefore, rehabilitation needs to be more involved in the management of DFWs and should be in all stages of diabetic care. In this review, we discuss literature data to bring rehabilitation perspective to the multidisciplinary management of DFWs.
RESUMO
BACKGROUND: Myiasis is a parasitic infestation of tissues or body cavities of mammals with dipterous larvae. The patients with diabetic foot ulcers are more vulnerable to acquiring infestation; however, the infestation may be neglected and mistreated in some cases. METHODS: Data were collected of twelve myiasis cases with diabetic foot ulcers in Nazli-Selim Eren Chronic Wound and Infections Care Unit, Aydin, Turkey between 2017 and 2019. Demographic, clinical characteristics of the patients and clinical examination of the wound were recorded. To morphology-based identification method of the agents, the developmental stages of the maggots were examined. RESULTS: The cases aged between 46 and 81 years (10 males, two females). Eight of the larvae collected from wounds had Calliphoridae and four had Sarcophagidae family. The larvae were infested right/left foot sole, thumb, ankle, and mostly left toes. The number of larvae collected from the cases ranged from 2 to 48. Third-stage larvae (L3) were mostly detected. Mixed (L1-L2, L2-L3) larvae were detected in a patient. The infestations were more common in July and August. According to the score of Infectious Diseases Society of America (IDSA), ten (83%) cases had moderate and two (17%) cases were mild diabetic foot infections (DFIs). CONCLUSION: Diabetic foot ulcers should be evaluated in terms of myiasis. This was the first study in our province indicating that myiasis should not be neglected and different species of flies were responsible for myiasis cases.
RESUMO
BACKGROUND: Involvement of the brain by Aspergillus fumigatus, named as invasive aspergillosis, is extremely rare. Definitive diagnosis needs isolation of the fungus from the tissue specimens and its culture. The disease is very resistant to treatment and quickly becomes fatal despite antifungal chemotherapy with AmB preparations, the drugs of choice for the infection. CASE DESCRIPTION: We hereby present a unique case of fungal granuloma of the brain due to A fumigatus, which was cured successfully by intensive antifungal treatment, along with a brief literature review. CONCLUSIONS: Although it is rare, we draw the attention to the fact that early diagnostic procedures with rapid confirmation of Aspergillus infection and an early initiation of therapy are pivotal for a benign clinical course in such cases. A complete regression of the disease could be achieved with medical therapy alone with conventional AmB or liposomal AmB combined with oral itraconazole even if a total surgical excision of the lesions could not be performed in complicated cases, as in our patient.

BACKGROUND: The study aimed to evaluate the ratio of venous contamination in diabetic cases without foot lesion, with foot lesion and with Charcot neuroarthropathy (CN). MATERIALS AND METHODS: Bolus-chase three-dimensional magnetic resonance (MR) of 396 extremities of patients with diabetes mellitus was analyzed, retrospectively. Extremities were divided into three groups as follows: diabetic patients without foot ulcer or Charcot arthropathy (Group A), patients with diabetic foot ulcers (Group B) and patients with CN accompanying diabetic foot ulcers (Group C). Furthermore, amount of venous contamination classified as no venous contamination, mild venous contamination, and severe venous contamination. The relationship between venous contamination and extremity groups was investigated. RESULTS: Severe venous contamination was seen in Group A, Group B, and Group C, 5.6%, 15.2%, and 34.1%, respectively. Statistically significant difference was seen between groups with regard to venous contamination. CONCLUSION: Venous contamination following bolus chase MR was higher in patients with CN.
RESUMO
OBJECTIVES: Acute liver failure is a rapidly progressive and life-threatening disease in children, whose clinical features differ from those of adults. MATERIALS AND METHODS: This is a review of a single center's experience with pediatric acute liver failure in a region with insufficient deceased donor support. The study is a retrospective review and analysis of 22 pediatric patients with acute liver failure between January 2007 and May 2013. RESULTS: The cause of acute liver failure was indeterminate in 45.4% of cases. Listing for liver transplant was required in 72.7% of patients, whereas 27.3% developed spontaneous remission. In the patients placed on the liver transplant wait list, 75% underwent liver transplant and 25% died before undergoing liver transplant. The presence of ascites, high-grade encephalopathy, and laboratory findings including high lactate dehydrogenase and phosphorous levels and international normalized ratio were significant parameters in selecting patients needing liver transplants. All liver transplants were from living donors. One- and 3-year patient survival rates after liver transplant were 75% and 75%. No serious donor complications occurred. CONCLUSIONS: Living-donor liver transplant may be the only option to save the lives of pediatric patients with acute liver failure, especially in regions with insufficient deceased-donor support. Timely referral to a multidisciplinary transplant center, expedient evaluation of living donors, and appropriate timing of transplant are crucial for a successful outcome.

AIM: Zygomycosis is a severe angioinvasive infection caused by Zygomycetes. We retrospectively investigated 16 cases of zygomycosis. MATERIALS AND METHODS: The data of patients, who had been followed between 2004 and 2010 in 8 tertiary-care teaching hospitals, were reviewed. Demographic characteristics, underlying diseases, and clinical signs and symptoms of the patients, as well as diagnostic methods, data obtained by radiological imaging methods, and the therapies, were recorded. Therapeutic approaches, antifungal agents and duration of use, and the characteristics of the cases were identified. RESULTS: The study included 11 female and 5 male subjects. The most common symptoms and clinical signs were fever (n = 9) and retro- orbital pain (n = 7). Rhinocerebral zygomycosis was the most common form. The mean time elapsed for diagnosis was 14.26 + 13.96 (range: 2-52) days. Antifungal therapy was given to 15 patients (94%). In addition to antifungal therapy, 12 patients underwent surgical intervention 1 to 4 times. The mean duration of receiving antifungal therapy was 61.4 + 58.02 (range: 1-180) days. The median duration of treatment was 62.5 (range: 42-180) days in survivors. CONCLUSION: Zygomycosis is an infectious disease with high mortality despite antifungal therapy and surgical interventions.
