Machine Learning Model Development to Predict Power Outage Duration (POD): A Case Study for Electric Utilities.

In the face of increasing climate variability and the complexities of modern power grids, managing power outages in electric utilities has emerged as a critical challenge. This paper introduces a novel predictive model employing machine learning algorithms, including decision tree (DT), random forest (RF), k-nearest neighbors (KNN), and extreme gradient boosting (XGBoost). Leveraging historical sensors-based and non-sensors-based outage data from a Turkish electric utility company, the model demonstrates adaptability to diverse grid structures, considers meteorological and non-meteorological outage causes, and provides real-time feedback to customers to effectively address the problem of power outage duration. Using the XGBoost algorithm with the minimum redundancy maximum relevance (MRMR) feature selection attained 98.433% accuracy in predicting outage durations, better than the state-of-the-art methods showing 85.511% accuracy on average over various datasets, a 12.922% improvement. This paper contributes a practical solution to enhance outage management and customer communication, showcasing the potential of machine learning to transform electric utility responses and improve grid resilience and reliability.

A successful treatment with intravenous lipid emulsion therapy in a child with verapamil poisoning.

In recent years, intravenous lipid emulsion therapy (ILE) was used for lipophilic drug intoxications, and successful results were obtained. In the literature, there is a small number of reported cases about verapamil intoxication and ILE therapy in the pediatric age group. We used ILE therapy in a 14-year-old girl with verapamil intoxication in the 2nd h of the pediatric intensive care unit stay, before using traditional treatments such as glucagon and hyperinsulinemic euglycemia. She had resistant bradycardia and hypotension which was unresponsive to inotropic agents and a successful result was obtained after using ILE treatment. We believe our report may contribute to the early use of ILE therapy for toxicity with calcium channel blockers such as verapamil in pediatric patients.

Comparison of DNA damage and proliferative capacities in smear samples of HPV positive and negative patients by micronucleus counting and AgNOR staining.

Human papillomavirus (HPV) is believed to cause cervical cancer. Thousands of women develop cancer and other diseases caused by HPV each year. HPV 16 and 18 types are found in approximately 70% of cervical cancers. Micronuclei are small chromosomal fragments that are considered indicators of DNA damage. AgNOR positive dots are useful for assessing proliferation. We investigated the relation between HPV-DNA, micronuclei and AgNOR in smear samples. Three groups were defined: HPV negative, 16/18 positive and other high-risk groups (31, 33, 35, 39, 45, 51, 52, 56, 58, 66 and 68) (HR). After typing, micronuclei were identified by Papanicolaou staining and AgNOR regions were detected by silver staining. Serum reactive protein (CRP) also was measured. We found that the average age of HPV negative patients was significantly greater than for the HPV positive groups. We also found that CRP levels were significantly higher in the HPV 16/18 positive group than HPV negative and other HPV group. We found that the number of micronuclei in the HPV 16/18 group was significantly greater than for the HPV negative group. Also, we found that AgNOR staining for the HPV 16/18 group was significantly greater than for the HPV negative group. We found that CRP level, cell proliferation and genome instability were increased in HPV positive patients. The AgNOR and micronucleus tests were useful for evaluating cell proliferation and DNA damage.

Chronic Boutonniere Deformity: Cross-Lateral Band Technique Using Palmaris Longus Autograft.

PURPOSE: The purpose of this study was to evaluate the outcomes of treatment of chronic boutonniere deformity with a reconstruction technique using palmaris longus autograft. MATERIALS AND METHODS: Seven patients with chronic, posttraumatic, flexible boutonniere deformities referred to our clinic between January 2010 and September 2014 were included in the study. In all 7 patients, the lateral bands were deficient or damaged beyond repair. A novel reconstruction technique for chronic boutonniere deformity utilizing palmaris longus autograft was used. The 2 lateral bands were reconstructed by attaching the palmaris longus tendon grafts from the lateral part of the central slip proximally to the volar aspect of the distal phalanx distally using pull-out sutures. The grafts were positioned so that they crossed over one another at the level of the middle phalanx. The patients were followed for a mean of 14 months (range, 12-16 months). The principal outcome measure was the range of motion of the proximal (PIP) and distal (DIP) interphalangeal joints. RESULTS: Before surgery, the average PIP joint active flexion was 69° (range, 60°-85°). After surgery, the average PIP joint active flexion increased to 92° (range, 90°-100°). Before surgery, the average PIP joint extension deficit was 54° (range, 40°-60°); after surgery, the average deficit was reduced to 7° (range, 5°-15°). Before surgery, the average DIP posture was 9° of hyperextension (range, 5°-12°); after surgery, DIP hyperextension was reduced to 2° (range, 0°-5°). Before surgery, the average DIP active flexion was 40° (range, 35°-55°); after surgery, this increased to 55° (range, 43°-72°). No patients developed a DIP flexion contracture. CONCLUSIONS: In the chronic boutonniere deformity, when the lateral bands are deficient or damaged, our cross-lateral band reconstruction technique using palmaris longus autograft is a treatment option with satisfactory results.

Supernumerary nostril: Congenital adrenal hyperplasia with a rare congenital anomaly.

Multiple or supernumerary nostril is a rare congenital anomaly with unknown etiology. The first case was reported by Lindsay as bilateral supernumerary nostrils. Supernumerary nostril cases are mostly unilateral and isolated. They are also reported with other congenital malformations like facial clefts and congenital anomalies like congenital auricular hypoplasia, congenital cataracts, eusophageal atresia and patent ductus arteriosus. Here, we report a case of supernumerary nostril with congenital adrenal hyperplasia.
