RESUMEN
BACKGROUND: Pediatric supracondylar humerus (SCH; AO/OTA13-M/3.1) and medial epicondyle fractures (AO/OTA13u-M/7.1) are common. Concomitant SCH with ipsilateral medial epicondyle fractures remain scarcely reported. We investigated the epidemiology, treatment, and outcomes of this rare, combined injury. METHODS: A retrospective review of pediatric patients with concomitant SCH and medial epicondyle fractures at a level 1 hospital from 2010 to 2020 was performed. Patient data, treatments, and outcomes were assessed. Radiographs were reviewed for fracture classification and alignment. Patients aged above 18 years and those with inaccessible imaging were excluded. Descriptive statistics were performed. RESULTS: Of 3344 patients undergoing surgery for SCH fractures, 14 (6 females, mean: 10.59 y) with concomitant SCH and medial epicondyle fractures were included. Overall, 28.6% of patients exhibited preoperative nerve palsies (3 PIN, 1 median nerve). There was 1 flexion type and 13 Gartland type III SCH fractures. Medial epicondyle fracture displacement averaged 4.13 mm (range: 2 to 7 mm). Thirteen medial epicondyle fractures occurred medial to the physis with 1 through the physis. Eight patients (57.1%) had medial fixation-7 medial pins, 1 medial screw-which captured both the medial epicondyle and medial column of the SCH fracture. Six medial epicondyles were treated closed. The average time to pin pull was 33.1 days (range: 27 to 51 d) with average follow-up of 138.6 days (range: 27 to 574 d). Overall, 50% of patients completed physical therapy (PT). Complications occurred in 4 cases: prominence of a medial pin, 1 patient required additional PT and dynamic splinting for loss of functional extension, 1 patient underwent a manipulation under anesthesia 3.5 months postoperatively for flexion contracture, and 1 patient developed medial epicondyle nonunion and SCH malunion that underwent corrective osteotomy 10.5 months postoperatively. CONCLUSIONS: Concurrent SCH and medial epicondyle fractures exhibited a high rate of nerve palsy (28.6%) and complications (28.6%) and were frequently referred to physical therapy. While patients treated without medial fixation went on to union, this combined injury might represent a relative indication for medial pinning of the SCH fracture. Further studies on this rare injury pattern are needed to determine optimal treatment methods. LEVEL OF EVIDENCE: Level IV-therapeutic.

OBJECTIVE: Chat generative pre-trained transformer (ChatGPT) has garnered attention in health care for its potential to reshape patient interactions. As patients increasingly rely on artificial intelligence platforms, concerns about information accuracy arise. In-toeing, a common lower extremity variation, often leads to pediatric orthopaedic referrals despite observation being the primary treatment. Our study aims to assess ChatGPT's responses to pediatric in-toeing questions, contributing to discussions on health care innovation and technology in patient education. METHODS: We compiled a list of 34 common in-toeing questions from the "Frequently Asked Questions" sections of 9 health care-affiliated websites, identifying 25 as the most encountered. On January 17, 2024, we queried ChatGPT 3.5 in separate sessions and recorded the responses. These 25 questions were posed again on January 21, 2024, to assess its reproducibility. Two pediatric orthopaedic surgeons evaluated responses using a scale of "excellent (no clarification)" to "unsatisfactory (substantial clarification)." Average ratings were used when evaluators' grades were within one level of each other. In discordant cases, the senior author provided a decisive rating. RESULTS: We found 46% of ChatGPT responses were "excellent" and 44% "satisfactory (minimal clarification)." In addition, 8% of cases were "satisfactory (moderate clarification)" and 2% were "unsatisfactory." Questions had appropriate readability, with an average Flesch-Kincaid Grade Level of 4.9 (±2.1). However, ChatGPT's responses were at a collegiate level, averaging 12.7 (±1.4). No significant differences in ratings were observed between question topics. Furthermore, ChatGPT exhibited moderate consistency after repeated queries, evidenced by a Spearman rho coefficient of 0.55 ( P = 0.005). The chatbot appropriately described in-toeing as normal or spontaneously resolving in 62% of responses and consistently recommended evaluation by a health care provider in 100%. CONCLUSION: The chatbot presented a serviceable, though not perfect, representation of the diagnosis and management of pediatric in-toeing while demonstrating a moderate level of reproducibility in its responses. ChatGPT's utility could be enhanced by improving readability and consistency and incorporating evidence-based guidelines. LEVEL OF EVIDENCE: Level IV-diagnostic.

The purposeof this study was to compare outcomes of operatively treated pediatric distal third tibial shaft fractures fixed with elastic nailing or plate fixation and to evaluate the incidence of concurrent distal tibia physeal fractures. Retrospective review identified skeletally immature patients that underwent operative fixation of distal third tibia fractures at a level 1 children's hospital from 2010 to 2020. Patient and fracture characteristics were recorded. Analysis of treatment outcomes was performed and rates of concurrent distal tibia physeal fractures were evaluated. Of the 214 surgically treated tibial shaft fractures, 43 were distal third fractures. A concurrent distal tibia physeal fracture was present in 32.6% of patients. These were significantly associated with spiral distal third tibial shaft fractures. The presence of concurrent physeal fractures did not affect patient treatment outcomes. Comparing elastic nailing versus open reduction and plating revealed no difference with time to fracture union, time of postoperative immobilization, or time to full weight-bearing. While elastic nailing was associated with increased coronal angulation, translation, and shortening of fractures on initial postoperative imaging, there was no difference in rates of malunion at final follow-up. In our series, there were no differences in treatment outcomes based on fixation method. Our operatively treated distal third tibial shaft fractures had a higher rate of associated distal tibial physeal fractures than previously published in the pediatric orthopedic literature. We recommend careful evaluation of the ankle for concurrent physeal injuries in patients with distal third tibial shaft fractures indicated for operative treatment. Level of evidence: level III therapeutic study - retrospective comparative study.

BACKGROUND: The newly developed app TellUs is a digital offering for psychiatric outpatient treatment that includes diagnostic and therapeutic tools. The aim of this study was to test the clinical efficiency and patient satisfaction of TellUs. METHODS: Sixty-four patients with depressive disorder took part in the study for 3 months. The intervention group was treated digitally with TellUs and the control group received visiting treatment (treatment as usual) during that time. RESULTS: In both groups, a significant decrease of depressive symptoms and general strain through psychological symptoms, along with an increase of quality of life in the psychological domain, was shown. Furthermore, both groups were highly satisfied with the treatment. CONCLUSIONS: TellUs was shown to be equivalent to treatment as usual in terms of clinical efficiency and patient satisfaction.

This study investigated the haemodynamic effects of adaptive servoventilation (ASV) in heart failure (HF) patients with Cheyne-Stokes respiration (CSR) versus healthy controls. Twenty-seven HF patients with CSR and 15 volunteers were ventilated for 1 h using a new ASV device (PaceWave™). Haemodynamics were continuously and non-invasively recorded at baseline, during ASV and after ventilation. Prior to the actual study, a small validation study was performed to validate non-invasive measurement of Stroke volume index (SVI). Non-invasive measurement of SVI showed a marginal overall difference of -0.03 ± 0.41 L/min/m(2) compared to the current gold standard (Thermodilution-based measurement). Stroke volume index (SVI) increased during ASV in HF patients (29.7 ± 5 to 30.4 ± 6 to 28.7 ± 5 mL/m(2), p < 0.05) and decreased slightly in volunteers (50.7 ± 12 to 48.6 ± 11 to 47.9 ± 12 mL/m(2)). Simultaneously, 1 h of ASV was associated with a trend towards an increase in parasympathetic nervous activity (PNA) in HF patients and a trend towards an increase in sympathetic nervous activity (SNA) in healthy volunteers. Blood pressure (BP) and total peripheral resistance response increased significantly in both groups, despite marked inter-individual variation. Effects were independent of vigilance. Predictors of increased SVI during ASV in HF patients included preserved right ventricular function, normal resting BP, non-ischaemic HF aetiology, mitral regurgitation and increased left ventricular filling pressures. This study confirms favourable haemodynamic effects of ASV in HF patients with CSR presenting with mitral regurgitation and/or increased left ventricular filling pressures, but also identified a number of new predictors. This might be mediated by a shift towards more parasympathetic nervous activity in those patients.

BACKGROUND: Nocturnal adaptive servoventilation (ASV) therapy is now frequently used to treat Cheyne-Stokes respiration (CSR), which is highly prevalent in patients with moderate-to-severe heart failure (HF) and characterized by periodical breathing (hyperventilation). OBJECTIVES: This study analyzed and compared the acute effects of a novel ASV device on carbon dioxide pressure (pCO2) and oxygen saturation (SaO2) in HF patients with CSR and healthy volunteers. The influence of being asleep or awake on the ASV algorithm was also determined. METHODS: All subjects underwent ASV (PaceWave™, ResMed) for 1 h. Transcutaneous pCO2 (PtcCO2) and SaO2 were assessed transcutaneously, while wakefulness was analyzed using EEG recordings. Assessments were made 30 min before and after ASV, and during 1 h of ASV. RESULTS: Twenty HF patients (19 male; age 79 ± 12 years) and 15 volunteers (13 male, age 25 ± 4 years) were included. When awake, ASV was associated with a trend towards a decrease in PtcCO2 and an increase in SaO2 versus baseline in HF patients (34.4 ± 3.2 to 33.7 ± 3.8 mm Hg and 93.8 ± 2.6 to 94.9 ± 2.6%, respectively) and volunteers (39.5 ± 3.0 to 38.2 ± 3.8 mm Hg and 96.9 ± 1.3 to 97.8 ± 0.9%). While asleep during ASV, PtcCO2 increased to 36.3 ± 3.8 mm Hg and SaO2 decreased to 93.8 ± 2.6% in HF patients, with similar changes in volunteers (PtcCO2 41.7 ± 3.0 mm Hg, SaO2 97.1 ± 1.2). All comparisons were statistically significant (p ≤ 0.05, except the PtcCO2 decrease in both groups when awake). CONCLUSIONS: ASV therapy might result in hyperventilation when subjects are awake, but while asleep, PtcCO2 increased to mid-normal values, effects that would be favorable in HF patients with CSR.

STUDY OBJECTIVES: This study investigated the implications of the revised scoring rules of the American Academy of Sleep Medicine (AASM) in patients with heart failure (HF) with Cheyne-Stokes respiration (CSR). METHODS: Ninety-one patients (NYHA ≥II, LVEF ≤45 %; age 73.6 ± 11.3 years old; 81 male subjects) with documented CSR underwent 8 h of cardiorespiratory polygraphy recordings. Those were analyzed by a single scorer strictly applying the 2007 recommended, 2007 alternative, and the 2012 scoring rules. RESULTS: Compared with the AASM 2007 recommended rules, apnea-hypopnea index (AHI) and hypopnea index (HI) increased significantly when the 2007 alternative and 2012 rules were applied (AHI 34.1 ± 13.5/h vs 37.6 ± 13.2/h vs 38.3 ± 13.2/h, respectively; HI 10.2 ± 9.4/h vs 13.7 ± 10.7/h vs 14.4 ± 11.0/h, respectively; all p < 0.001). Duration of CSR increased significantly with the alternate versus recommended 2007 rules (182.2 ± 117.0 vs 170.1 ± 115.0 min; p ≤ 0.001); there was a significant decrease in CSR duration for the 2012 versus 2007 alternative rules (182.2 ± 117.0 vs 166.7 ± 115.4 min; p ≤ 0.001). CONCLUSION: AHI was higher using the AASM 2012 scoring rules due to a less strict definition of hypopnea. Data on the prognostic effects of CSR in patients with HF and the benefits of treatment are mostly based on the AASM 2007 recommended rules, so differences between these and the newer version need to be taken into account.

PURPOSE: Using pulse transit time (PTT) and an ECG appears to be a promising alternative for invasive or noninvasive monitoring of blood pressure (BP). This study assessed the validity of PTT for BP monitoring in clinical practice. METHODS: Twenty-nine patients with chronic heart failure (HF; 27 male, 70.5 ± 9.9 years) and nocturnal Cheyne-Stokes respiration were noninvasively ventilated for one hour using adaptive servoventilation (ASV) therapy (PaceWave, ResMed). BP was measured using two devices (oscillometrically via Task Force Monitor, CNSystems and PTT via SOMNOscreen, Somnomedics) at least every 7 min for 30 min before, during, and after ASV. RESULTS: Mean systolic BP was 118.1 ± 14.4 mmHg vs. 115.9 ± 14.1 mmHg for oscillometric method vs PTT, respectively. Corresponding values for diastolic BP were 72.3 ± 10.3 mmHg and 69.4 ± 11.1 mmHg. While clinically comparable, differences between the two methods were statistically significant (p < 0.05). The difference between the two methods showed an increasing trend over time. A total of 18.5 % of PTT-based measurements could not be analyzed. The direction of a change in BP was opposite for PTT vs oscillometry for 17.0 % and 32.8 % of systolic and diastolic BP measurements, respectively. CONCLUSIONS: When monitoring BP in HF patients, overall BP monitoring using PTT is comparable to oscillometry for a period of 2 h (including a 1-h ASV phase). However, PTT shows a tendency to underestimate BP over time and during ASV.
