[Intraneural synovial cyst of the external sciatic popliteal nerve].
The authors report a case of an intraneural ganglion of the peroneal nerve. The cystic material was found to expand the neural sheath, while the neural fasciculi were few and atrophic. A communication between the intraneural cyst and the proximal tibio-peroneal joint was demonstrated. An hypothesis for the pathogenetic basis of intraneural ganglia is presented

Clinical and radiographic evaluation of the Codivilla method of surgical correction of congenital club foot. Medium-term follow-up of 235 cases.
The authors review 30 patients with congenital club foot (CCF) who were treated surgically by a slightly modified Codivilla technique. Clinical morphologic, and functional follow-up was performed an average of 10 years later, and the findings were compared to the radiographic features. The final outcome was rated good in 41% of the cases, fair in 29%, and unsatisfactory in 30%. The authors found a close correlation between the grade of the initial deformity and the final outcome. Some sign of the deformity always remained, even when the functional outcome was excellent

Enhancing hydroelectric inflow prediction in the Brazilian power system: A comparative analysis of machine learning models and hyperparameter optimization for decision support
Electricity generation in Brazil heavily depends on hydroelectric power, making it vulnerable to fluctuations due to its reliance on weather patterns. Accurately forecasting water inflow into hydroelectric plants is vital for the National Electric System Operator to make decisions regarding the monthly scheduling and operation of the power system. In this paper, an evaluation of predicted flows for a 14-day horizon are evaluated for the Tucuruíhydroelectric plant, located in the Tocantins river in the North of Brazil. The temporal fusion transformer (TFT), long short-term memory (LSTM), and temporal convolutional networks (TCN) are compared. The findings demonstrate that the TFT is a more suitable alternative than LSTM and TCN models for predicting inflows for the next 14 days. The TFT model is hypertuned by Optuna to achieve an optimized structure (h-TFT). The h-TFT had a mean absolute percentage error of 13.1 and a Nash–Sutcliffe of 0.96, outperforming its initial version and even the bidirectional LSTM model in benchmarking. Based on the error results, h-TFT showed promise for flow forecasting and provides insights into decision-making processes in the Brazilian electricity sector
Fracture with loss of the proximal femur in a child. A case report.
An 8 year old child was involved in a road accident and sustained a large wound in the left groin; radiographs showed a fracture with loss of the proximal femur. After skeletal traction for 80 days, there was bony regeneration of the proximal femur. At 8 months she was able to walk without support and her left leg was 2 cm only shorter than the right
