PurposeTo investigate a multi-parametric protocol for breast MRI examination and lesions assessment correlated to the American College of Radiology (ACR) breast imaging reporting and data system (BI-RADS) categorization, and to improve the management of the breast lesions.Materials and Methods 301 pathologically confirmed lesions on 278 patients were retrospectively included. The scan protocol used a dynamic contrast enhancement sequence (DCE) of 1 mm×1 mm×1 mm spatial resolution, 120 temporal resolution and a diffusion weighted imaging (DWI) of b=1000 s/mm2. The malignant morphological features on the early-enhanced images, type II or III time intensity curve and the apparent diffusion coefficient (ADC) value less than benign/malignant threshold was equally weighted. Each was given 1 point when present malignant features and treated different on mass and non-mass-like enhancement lesions. When the sum of score was ≥2 points, the lesion was categorized as BI-RADS 5. When the sum of score was 1 point, the lesion was categorized as BI-RADS 4. When the sum of score was <1 point, the lesion was categorized as BI-RADS 3. The other specific benign findings were categorized as BI-RADS 2. No abnormality on DWI, DCE, T2WI and T1WI was categorized as BI-RADS 1. The final categories were correlated to the pathological grades as benign (B), high risk (HR) and malignant (M).Results When grouped HR as malignant (M+HR), the area under curve (AUC) of the ROC was 0.860. When grouped HR as benign (B+HR), the AUC of the ROC was 0.876, and the optimized sensitivity, specificity and accuracy was 85.3%, 86.8% and 85.1%, respectively, which were better than the other grouping. If the management of HR lesions could be lumptoectomy or short-term follow-up, the positive predictive value (PPV) of BI-RADS 5 for excisable lesions (M+HR) was 93.2%, the PPV of BI-RADS 4 for excisable lesions (M+HR) was 46.9% and the biopsy was essential. The PPV of BI-RADS 3 and below for follow-up lesions (B+HR) was 90.4%.Conclusion A simple diagnosis algorithm was established, which equally weighted the DCE morphological feature, DCE-TIC and DWI-ADC. The diagnosis protocol was well consistent with BI-RADS categorization and could predict the benign, high risk and malignant lesions in pathology as well as the proper management.

Objective:To explore potential predictors of refractory Mycoplasma pneumoniae pneumonia (RMPP) in early stage. Methods:The prospective multicenter study was conducted in Zhejiang, China from May 1 st, 2019 to January 31 st, 2020. A total of 1 428 patients with fever >48 hours to <120 hours were studied. Their clinical data and oral pharyngeal swab samples were collected; Mycoplasma pneumoniae DNA in pharyngeal swab specimens was detected. Patients with positive Mycoplasma pneumoniae DNA results underwent a series of tests, including chest X-ray, complete blood count, C-reactive protein, lactate dehydrogenase (LDH), and procalcitonin. According to the occurrence of RMPP, the patients were divided into two groups, RMPP group and general Mycoplasma pneumoniae pneumonia (GMPP) group. Measurement data between the 2 groups were compared using Mann-Whitney U test. Logistic regression analyses were used to examine the associations between clinical data and RMPP. Receiver operating characteristic (ROC) curves were used to analyse the power of the markers for predicting RMPP. Results:A total of 1 428 patients finished the study, with 801 boys and 627 girls, aged 4.3 (2.7, 6.3) years. Mycoplasma pneumoniae DNA was positive in 534 cases (37.4%), of whom 446 cases (83.5%) were diagnosed with Mycoplasma pneumoniae pneumonia, including 251 boys and 195 girls, aged 5.2 (3.3, 6.9) years. Macrolides-resistant variation was positive in 410 cases (91.9%). Fifty-five cases were with RMPP, 391 cases with GMPP. The peak body temperature before the first visit and LDH levels in RMPP patients were higher than that in GMPP patients (39.6 (39.1, 40.0) vs. 39.2 (38.9, 39.7) ℃, 333 (279, 392) vs. 311 (259, 359) U/L, both P<0.05). Logistic regression showed the prediction probability π=exp (-29.7+0.667×Peak body temperature (℃)+0.004×LDH (U/L))/(1+exp (-29.7+0.667×Peak body temperature (℃)+0.004 × LDH (U/L))), the cut-off value to predict RMPP was 0.12, with a consensus of probability forecast of 0.89, sensitivity of 0.89, and specificity of 0.67; and the area under ROC curve was 0.682 (95% CI 0.593-0.771, P<0.01). Conclusion:In MPP patients with fever over 48 to <120 hours, a prediction probability π of RMPP can be calculated based on the peak body temperature and LDH level before the first visit, which can facilitate early identification of RMPP.

Objective:To explore rational surgical treatment for childhood nail matrix nevi.Methods:A retrospective analysis was conducted on clinical data from 35 children with pathologically confirmed nail matrix nevi, who received surgical treatment in Children′s Hospital of Chongqing Medical University from September 2015 to March 2019. Different surgical approaches were adopted according to the site and width of lesions. For lesions with a width of ≤ 3 mm, the nail bed and nail matrix lesions were directly excised with 1-to-2-mm margins and sutured in 11 cases. For lesions with a width of > 3 mm, one of the following 3 surgical procedures was selected by the children′s parents: (1) shaving of nail bed and nail matrix lesions under a microscope at ×8 magnification (8 cases) ; (2) excision of lesions followed by full-thickness skin grafting on the periosteum of the phalanx (8 cases) ; (3) excision of lesions of the second to fifth fingers followed by transfer of skin flaps from the thenar muscle area and full-thickness skin grafting (5 cases) , or excision of lesions of the thumb followed by abdominal-wall flap transfer (3 cases) . The patients were followed up for 12 months, and clinical efficacy was evaluated.Results:During the follow-up, no recurrence occurred in the 11 cases receiving direct excision and suture, with good appearances and longitudinal linear scars on the nail. Among the 8 cases receiving shaving therapy under a microscope, 4 experienced relapse during the follow-up of 6 - 12 months, and the nail/toenail plates were rough and poor in lustrousness in the other 4 without recurrence. No recurrence was observed in the 8 cases receiving excision of the lesions and full-thickness skin grafting, of whom 1 experienced skin graft necrosis, and skin grafts survived with obvious pigmentation in the other 7 cases. Among cases receiving excision of the lesions combined with transfer of skin flaps from the thenar muscle area or abdominal-wall flap transfer, no recurrence was observed, and all transferred flaps survived; good appearances, nearly normal color and gloss of nails were obtained in the cases after transfer of skin flaps from the thenar muscle area, while the color and gloss of postoperative nails were markedly different from those of normal nails in the cases receiving abdominal-wall flap transfer.Conclusion:For nail matrix nevi with a width of ≤ 3 mm, direct excision and suture with 1-to-2-mm margins are recommended; for those with a width of > 3 mm, excision of lesions combined with full-thickness skin grafting, transfer of skin flaps from the thenar muscle area or abdominal-wall flap transfer is recommended; the shaving procedure under a microscope should be used with caution.

Objective:To evaluate the initial clinical outcome of applying a comprehensive debulking procedure centered on the digital and plantar flaps with comparatively healthy proximal pedicle to reconstruct the hypertrophic toes and forefoots in one-stage surgery in multiple toes macrodactyly in children.Methods:The clinical data of children with macrodactyly deformity treated by the Department of Burn and Plastic Surgery in Children’s Hospital of Chongqing Medical University from January 2022 to October 2023 were retrospectively analyzed. Design toe and plantar arbitrary flaps with a few vascular perforating branches which pedicle at the comparatively healthy proximal side and resect all tissues beyond the normal length. In severe toe, a composite tissue nail-flap with the artery was dissected to reconstruct the toenail. Fat debulking on the surface of deep plantar fascia as well as within the osseofascial sheath, resecting partially of the fatty infiltrated nerve, transverse and longitudinal osteotomy to shorten and narrowed phalanxes without epiphyseal block, arthroplasty and flexor tendon tightening were performed. Finally, toes shaped by wrapping toe flaps, and pelmas restored by plantar flaps which both with comparatively healthy proximal pedicle. The operation time, healing time, and whether the toes and toenails are preserved were all recorded. The maximum circumference of both foot, the difference in shoe size, the presence of skin ulcers, wound scars, toe webbing morphology, the presence of basic sensation, and the satisfaction of parents were followed-up after surgery. The modified follow-up questionnaire was used to evaluate the surgical effect, the total score is 0-12 points, and the higher the score, the better the surgical outcome. Descriptive methods was used for statistical analysis, and the measurement data conforming to normal distribution were expressed as Mean±SD.Results:A total of 15 patients were enrolled, including 11 males and 4 females. The median age at the time of operation was 2.75 years (0.9-10.8 years). There were 11 cases with 2 toes and 4 cases with 3 toes, a total of 34 toes involved. The average surgical duration was 4.13 hours (3.25 hours for 2 toes and 5.00 hours for 3 toes). Only one severe case with 3 toes involved was amputated the biggest toe ray and totally 2 toe nail flaps were harvested unsuccessfully intraoperative. Except 3 toes had distal skin partially necrosis and 2 nail flaps were completely necrotic which healed after dressing changes, the rest of the toes were healing well after operation. The average follow-up time was 4.8 months (3-11 months), the difference of circumference was less than 1.5 cm, as well as in length was less than 0.5 cm between feet and all children were able to wear the appropriate shoes with same size. A total of 4 toes failed to retain toenails, and 1 had a very thin toenail. Except for one case with insufficient web depth, the other toe webs were close to normal. There was no skin ulcer occurred, the basic sensation of the feet was present, and wound scars were inconspicuous. The score of the modified questionnaire was 10.54±0.88, all parents were satisfied with the results.Conclusion:Comprehensive procedure centered on the digital and plantar flaps with comparatively healthy proximal pedicle for debulking multiple toes macrodactyly in children could completely excise distal hypertrophic tissues in a single operation, and the size of the affected feet and toes can be greatly reduced to wearing shoes of the same size, and have a high success rate in preserving the toes, as well as nails. The reconstructed feet, toes and toe webbing have near-normal morphology, hidden scar, no ulcers after walked and achieve a good initial effect.

Objective:To analyze and report the anatomical characteristics, surgical management and clinical outcome for preaxial polysyndactyly with varus deformity.Methods:We retrospectively reviewed our database of cases with preaxial polysyndactyly in the Department of Burn and Plastic Surgery of Children’s Hospital of Chongqing Medical University from January 2010 to January 2020. The clinical manifestations are duplicated hallux, with complete fusion of the main and auxiliary hallux, tibial hallux dysplasia, and fibular hallux with obvious varus deformity. The anatomical characteristics of this special polysyndactyly, surgical incision design, osteoarticular correction methods were analyzed, and the axial line of the big toe after the operation and its influence on the walking function were followed up.Results:A total of 10 children with preaxial polysyndactyly (12 toes) were enrolled, including 6 male and 4 female patients. Age ranged from 5 to 45 months, with an average of 19.3 months. Eight cases were unilateral, and 2 cases were bilateral. All the cases had duplicated hallux, with tibial hallux dysplasia and proximal displacement. The fibular hallux was dominant but with varus deformity to varying degrees (varus angle 25°-90°, mean 55°). During the operation, the abductor hallucis (AbdH) was found to be attached to the tibial hallux, and the metatarsophalangeal (MTP) joint of the dominant hallux was dislocated to the tibial side, with an inclination of the joint surface. Incision design: zigzag incision around extra toes were used in 3 toes with varus angle from 25° -40°, proximal pedicle flap of the extra toe was taking in 3 toes with varus angle from 45°-90°, and double Z-plasty incision was designed in 6 toes which varus angle is from 75°-90°. Correction of bone and joint: after extra toe resected, the axis of two cases with mild hallux varus was corrected by releasing the soft tissue contracture in the tibial side of the main toe and reducing the joint. The other 10 cases were obtained completely axially corrected after opening osteotomy performed at the tibial side of the metatarsal bone or phalanx, and nine of them were treated with bone graft for filling the bone defect. Wound closure: all wounds were successfully closed. Among these, 2 of the 3 toes that taking transferred proximal pedicle flap of extra toe were supplemented with skin grafts due to skin deficiency. Although the varus angle was large, the wounds of 6 toes with double Z-plasty incision were completely closed after lengthened the longitudinal skin of the tibial side of the big toe. Two cases were lost to follow-up, and the other 8 cases (10 toes) were followed up for 5-38 months (mean 13 months). Except for 1 toe with insufficient correction (hallux varus 15°) and 2 toes with overcorrection (hallux valgus 15°, 20°), the axial lines of the other big toes were normal. All cases wore shoes and walked normally.Conclusions:The anatomical characteristics of this type of preaxial polysyndactyly are the AbdH terminating in the deformed tibial toe and the medial dislocation of the associated main hallux MTP joint resulting in varus and the oblique planar of the metatarsal articulations. The deformity of hallux varus and the deficiency of tibial skin were the characteristics and the difficulties of this special type of preaxial polysyndactyly. Good axial correction can be obtained by means of opening osteotomy and intraoperative release of abductor insertion. Then the wound can be closed at one stage without skin grafting by using a double Z-plasty incision which could fully elongate the tibial side skin.
