Cough is a very common symptom causing medical consult. Several remedies are readily available in the market however these are currently not recommended among the pediatric population due to a few reasons which include the benign nature of acute cough, limited effectivity and lack of support from the United States Food and Drug Administration (USFDA) due to abuse potential.

We report a case of a 2-year-old male, no known co-morbidities with a 2 week history of upper respiratory tract infection. Initial assessment showed viral infection hence patient was given medications for symptomatic treatment. However, l week after, patient still presented with symptomatic persistent coughing that disrupted his activities of daily living, hence antitussive medication was already prescribed. After another 7 days, there was still persistence of symptoms, hence patient was given a trial medication of Pregabalin 0.7 milligram/kg/dose which noted instant cough relief one hour after the initial intake. Patient also reported to be more playful, improved sleep at night and improved appetite. Patient received total of 2 doses of Pregabalin in the span of 48 hours. On the third day, patient was still coughing but reported to be significantly less frequent and more productive, hence medication was then put on hold. Patient continuously improved after 5 more days and was eventually cough free.

This case report demonstrates the adequacy of Pregabalin as a supportive antitussive medication in a patient with an acute cough secondary to a viral infection.

Sweat pores function is the ascending and descending of Qi. The human body maintains a continuous, holistic, and dynamic balance through the functioning of sweat pores as well as the Qi movement and transformation in the spleen, stomach, and triple energizer. Sweat pores play a crucial role in the generation and development of Zang-fu organs, essence and spirit, and body and orifices, as well as in the onset and progression of diseases. Oxidative stress significantly affects the regulation of inflammation in allergic rhinitis(AR), induces the pathological damage to nasal epithelial cells, and alters immune activity, serving as a key mechanism exacerbating AR symptoms. This mechanism closely aligns with the pathogenesis associated with dysfunction in the sweat pore-Qi-triple energizer system. In recent years, oxidative stress and antioxidants in AR have received increasing attention. Elevated levels of reactive oxygen species, fractional exhaled nitric oxide, and malondialdehyde have become key indicators for the early diagnosis of AR. Classical prescriptions, empirical prescriptions, and newly developed preparations of traditional Chinese medicine(TCM) for external use with anti-inflammatory, anti-allergic, and immune-regulatory effects via antioxidant pathways have demonstrated definite efficacy in treating AR. This provides a basis for understanding the pathogenesis of AR in TCM from a modern medical perspective. Therefore, this paper systematically examines the relationship between the sweat pore-Qi-triple energizer system and AR, incorporating the oxidative stress mechanism into the research on pathogenesis of the disorders. Furthermore, methods for treating AR in children are proposed with TCM preparations for external use which aimed at opening nasal sweat pores, dispersing, searching, channeling with aroma, warming, and dredging, regulating Qi movement in spleen, warming Yang Qi to promote urination, and clearing latent wind to inhibit liver depression.

Jiuwei Xifeng Granules have become a Chinese patent medicine in the market. Because the formula contains Os Draconis, a top-level protected fossil of ancient organisms, the formula was to be improved by replacing Os Draconis with Ostreae Concha. To evaluate whether the improved formula has the same effectiveness and safety as the original formula, a randomized, double-blind, parallel-controlled, equivalence clinical trial was conducted. This study enrolled 288 tic disorder(TD) of children and assigned them into two groups in 1∶1. The treatment group and control group took the modified formula and original formula, respectively. The treatment lasted for 6 weeks, and follow-up visits were conducted at weeks 2, 4, and 6. The primary efficacy endpoint was the difference in Yale global tic severity scale(YGTSS)-total tic severity(TTS) score from baseline after 6 weeks of treatment. The results showed that after 6 weeks of treatment, the declines in YGTSS-TSS score showed no statistically significant difference between the two groups. The difference in YGTSS-TSS score(treatment group-control group) and the 95%CI of the full analysis set(FAS) were-0.17[-1.42, 1.08] and those of per-protocol set(PPS) were 0.29[-0.97, 1.56], which were within the equivalence boundary [-3, 3]. The equivalence test was therefore concluded. The two groups showed no significant differences in the secondary efficacy endpoints of effective rate for TD, total score and factor scores of YGTSS, clinical global impressions-severity(CGI-S) score, traditional Chinese medicine(TCM) response rate, or symptom disappearance rate, and thus a complete evidence chain with the primary outcome was formed. A total of 6 adverse reactions were reported, including 4(2.82%) cases in the treatment group and 2(1.41%) cases in the control group, which showed no statistically significant difference between the two groups. No serious suspected unexpected adverse reactions were reported, and no laboratory test results indicated serious clinically significant abnormalities. The results support the replacement of Os Draconis by Ostreae Concha in the original formula, and the efficacy and safety of the modified formula are consistent with those of the original formula.

This study aims to explore whether Guzheng playing training has a positive impact on the brain functional state of children with Autism Spectrum Disorder (ASD) based on power spectral and sample entropy analyses. Eight ASD participants were selected to undergo four months of Guzheng playing training, with one month as a training cycle. Electroencephalogram (EEG) signals and behavioral data were collected for comparative analysis. The results showed that after Guzheng playing training, the relative power of the alpha band in the occipital lobe of ASD children increased, and the relative power of the theta band in the parietal lobe decreased. The differences compared with typically developing (TD) children were narrowed. Moreover, some channels exhibited a gradual increase or decrease in power with the extended training period. Meanwhile, the sample entropy parameter also showed a similar upward trend, which was consistent with the behavioral data representation. The study shows that Guzheng training can enhance the brain function of ASD patients, with better effects from longer training. Guzheng playing training could be used as a daily intervention for autism.

To facilitate the early intelligent screening of pediatric genu valgum, this study develops a deep learning-based gait recognition model tailored for clinical application. The model is constructed upon a three-dimensional residual network architecture and incorporates a triplet attention module alongside a spatial hierarchical pooling module, jointly enhancing feature interaction across temporal, spatial, and channel dimensions. This design ensures an optimal balance between representational capacity and computational efficiency. Evaluated on a self-constructed dataset, the model achieves precision of 98.0%, 97.1%, and 96.5%, recall rates of 97.5%, 97.0%, and 95.0%, and F ₁-scores of 0.98, 0.97, and 0.96 on the training, validation, and test sets, respectively, demonstrating excellent recognition performance and strong generalization ability. Ablation experiments confirm the importance of the proposed model's core components in improving performance, and comparative experiments further highlight its significant advantages in recognition accuracy and robustness. Visualization experiments reveal that the model effectively focuses on key regions of gait images, with attention regions aligning closely with clinical anatomical landmarks, thereby enhancing the interpretability of the model's decision-making in clinical applications. In summary, the proposed model not only offers an efficient and reliable technical solution for early intelligent screening of genu valgum in children, but also provides a practical pathway for applying gait recognition technology in medical diagnosis.

OBJECTIVE: To compare the effectiveness of ultrasound-guided closed reduction with Kirschner wire fixation and open reduction with Kirschner wire fixation in the treatment of humeral lateral condyle fracture (HLCF) in children. METHODS: A clinical data of 53 children with HLCF admitted between May 2020 and April 2023 and met selective criteria was retrospectively analyzed. Of these, 25 cases were managed with closed reduction and Kirschner wire fixation under ultrasound guidance (closed group), while 28 cases underwent open reduction and Kirschner wire fixation (open group). There was no significant difference between the two groups in terms of gender, age, cause of injury, fracture side, fracture classification, and time from injury to operation ( P>0.05). The following variables were recorded and compared between the two groups: operation time, intraoperative fluoroscopy frequency, fracture healing time, incidence of complications, and the Flynn elbow function score at last follow-up. RESULTS: In the closed group, the fractures were successfully reduced under ultrasound guidance, with no nerve damage reported in either group. The operation time and intraoperative fluoroscopy frequency were significantly less in the closed group than in the open group ( P<0.05). One case of infection (Kirschner wire irritation) was observed in the closed group, while 3 cases in the open group (2 of Kirschner wire irritation and 1 of incision infection). However, the difference in the incidence of infection between the two groups was not significant ( P>0.05). All patients in both groups were followed up 6-18 months (mean, 10.2 months). X-ray examinations confirmed that fractures had healed in both groups, with no significant difference in healing time ( P>0.05). During follow-up, 5 cases of lateral humeral process formation were observed in the closed group, compared to 12 cases in the open group, although this difference was not significant ( P>0.05). At last follow-up, the excellent and good rate of elbow joint function was evaluated as 96.0% (24/25) in the closed group and 92.9% (26/28) in the open group according to the Flynn scoring criteria, with no significant difference between the two groups ( P>0.05). Both groups showed no occurrence of ossifying myositis or elbow internal/external rotation. CONCLUSION The effectiveness of ultrasound-guided closed reduction and Kirschner wire fixation in the treatment of HLCF in children is comparable to open reduction and Kirschner wire fixation, but the former can reduce operation time and intraoperative fluoroscopy frequency, and obtain lower the incidence of complications.

OBJECTIVE: To discuss the elbow skin fold extension line in Kirschner wire internal fixation of extended supracondylar humeral fractures in children. METHODS: The clinical data of 58 children with extended supracondylar fractures of the humerus who met the selection criteria between August 2021 and July 2024 were retrospectively analyzed. In 28 cases, needle placement of medial epicondyle of humerus was performed with the assistance of the elbow skin fold extension line (study group), and 30 cases were assisted by routine touch of the medial epicondyle of the humerus (control group). There was no significant difference in baseline data such as gender, age, side, cause of injury, Gartland type, Kirschner wire configuration, and time from injury to operation between the two groups ( P>0.05). The closed reduction rate, total operation time, time of medial humeral condyle pin placement, fluoroscopy times during medial pin placement, rate of one-time determination of medial entry point, ulnar nerve injury incidence, and fracture healing time were recorded and compared between the two groups. At the same time, the closed reduction rate of patients with the time from injury to operation ≤24 hours and >24 hours was compared. The elbow function was evaluated by Mayo elbow function score. RESULTS: The closed reduction rate of the study group was significantly higher than that of the control group ( P<0.05). Among all patients, the closed reduction rate of patients with the time from injury to operation ≤24 hours [73.3% (22/30)] was significantly higher than that of patients >24 hours [42.9% (12/28)] ( χ ²=5.545, P=0.019). The total operation time, medial needle placement time, and fluoroscopy times in the study group were significantly less than those in the control group, and the one-time determination rate of medial needle entry point in the study group was significantly higher than that in the control group ( P<0.05). There were 4 cases of ulnar nerve injury in the control group, and no ulnar nerve injury in the study group, but there was no significant difference in the incidence of ulnar nerve injury between the two groups ( P>0.05). All patients were followed up 6-12 months (mean, 8 months). There was no bone nonunion in both groups, and the fracture healing time of the study group was significantly shorter than that of the control group ( P<0.05). Volkmann ischemic contracture, heterotopic ossification, myositis ossificans, and premature epiphyseal closure were not observed after operation. No complications such as loosening or fracture of Kirschner wire occurred. At last follow-up, the Mayo elbow joint function score was used to evaluate function, and there was no significant difference between the two groups ( P>0.05). CONCLUSION In the treatment of extended supracondylar fractures of the humerus in children, the elbow skin fold extension line can help to quickly locate the medial epicondyle of the humerus, quickly insert Kirschner wire, and reduce the operation time and trauma.

OBJECTIVE: To investigate the effectiveness of Salter osteotomy combined with subtrochanteric shortening and derotational osteotomy in treating Tönnis type Ⅲ and Ⅳ developmental dysplasia of the hip (DDH) in children and explore the urgical timing. METHODS: A retrospective collection was performed for 74 children with Tönnis type Ⅲ and Ⅳ DDH who were admitted between January 2018 and January 2020 and met the selection criteria, all of whom were treated with Salter osteotomy combined with subtrochanteric shortening and derotational osteotomy. Among them, there were 38 cases in the toddler group (age, 18-36 months) and 36 cases in the preschool group (age, 36-72 months). There was a significant difference in age between the two groups ( P<0.05), and there was no significant difference in gender, side, Tönnis typing, and preoperative acetabular index (AI) ( P>0.05). During follow-up, hip function was assessed according to the Mckay grade criteria; X-ray films were taken to observe the healing of osteotomy, measure the AI, evaluate the hip imaging morphology according to Severin classification, and assess the occurrence of osteonecrosis of the femoral head (ONFH) according to Kalamchi-MacEwen (K&M) classification criteria. RESULTS: All operations of both groups were successfully completed, and the incisions healed by first intention. All children were followed up 14-53 months, with an average of 27.9 months. There was no significant difference in the follow-up time between the two groups ( P>0.05). At last follow-up, the excellent and good rates according to the Mckay grading were 94.73% (36/38) in the toddler group and 83.33% (30/36) in the preschool group, and the difference between the two groups was significant ( P<0.05). The imaging reexamination showed that all osteotomies healed with no significant difference in the healing time between the two groups ( P>0.05). There was no significant difference in AI between the two groups at each time point after operation ( P>0.05), and the AI in the two groups showed a significant decreasing trend with time extension ( P<0.05). The result of Severin classification in the toddler group was better than that in the preschool group at last follow-up ( P<0.05). There was no significant difference in the incidence of ONFH between the two groups ( P>0.05). In the toddler group, 2 cases were K&M type Ⅰ; in the preschool group, 3 were type Ⅰ, and 1 type Ⅱ. There was no dislocation after operation. CONCLUSION Salter osteotomy combined with subtrochanteric shortening and derotational osteotomy is an effective way to treat Tönnis type Ⅲ and Ⅳ DDH in children, and surgical interventions for children aged 18-36 months can achieve better results.

OBJECTIVE: To investigate short-term effectiveness of using expert adolescent lateral femoral nail (EALFN) in treating femoral shaft fractures in older children and adolescents. METHODS: A retrospective analysis was conducted on the clinical data of 17 patients with femoral shaft fractures who met the inclusion criteria and were admitted between July 2020 and June 2024. All fractures were fixed with EALFN after reduction. There were 11 males and 6 females, with a mean age of 13.3 years (range, 11-16 years). The average body weight was 51.2 kg (range, 40-84 kg), and the average height was 162.1 cm (range, 150-172 cm). The causes of injury included traffic accidents ( n=9), falling from height ( n=1), and simple falls ( n=7). One patient had an open fracture treated with an external fixator and experienced delayed fracture healing. The remaining patients were closed fractures, with an average time from injury to operation of 5.8 days (range, 2-10 days). Operation time and postoperative hospital stay were documented. During follow-up, X-ray films were taken to observe the fracture healing, and the bilateral femoral length, femoral neck-shaft angle, widest femoral neck diameter (FND), and articular trochanteric distance (ATD) were measured at last follow-up. Hip function was assessed using the Harris score. The differences in the all indicators between the healthy and affected sides were compared. RESULTS: The operation time ranged from 65 to 130 minutes (mean, 94.1 minutes). Postoperative hospital stay ranged from 5 to 40 days (mean, 16.7 days). All patients were followed up 7-36 months (mean, 14.4 months). One patient exhibited delayed fracture healing during follow-up. The distal locking nail was removed at 6 months after operation, and partial weight-bearing was initiated following dynamic fracture stabilization. The fracture healing was achieved, and the intramedullary nail was removed at 24 months after operation. The other fractures healed with the healing time of 6-20 months (mean, 9.6 months), and the intramedullary nails were removed. During follow-up, no femoral fracture, abnormal development of the greater trochanter, or ischemic necrosis of the femoral head occurred. At last follow-up, there was no significant difference in femoral length, femoral neck-shaft angle, FND, ATD, or Harris score between the affected and healthy sides ( P>0.05). CONCLUSION For older children and adolescents with femoral neck fractures, the application of EALFN fixation aligns more closely with the principles of intramedullary central fixation and rapid rehabilitation. This approach is associated with fewer complications and superior short-term effectiveness.
