Objective:To comprehensively evaluate treatment outcomes and assisted reproductive approaches in infertility patients with CYP17A1-deficient congenital adrenal hyperplasia [including 17α-hydroxylase/17,20-lyase deficiency (17-OHD) and isolated 17,20-lyase deficiency (IDL)]. Methods:In this study, PubMed, Embase, Web of Science, Ovid, CNKI, Wanfang Data base, and the Chinese Biomedical Literature Database were systematically searched. The data extracted included basic patient information, treatment plans, and pregnancy outcomes, which were then analyzed descriptively.Results:Totally 19 articles were included, covering 23 cases of successful live births. Among the 23 patients with successful live births, there were 19 patients with 17-OHD, including 17 cases became pregnant through in vitro fertilization and embryo transfer (IVF-ET), 1 case through natural pregnancy, and 1 case through oocyte donation pregnancy; there were 4 cases with IDL, including 2 cases through natural pregnancy and 2 cases through IVF-ET pregnancy. Conclusion:IVF-ET is the preferred fertility treatment option for patients with partial form of 17-OHD. For IDL patients who have natural ovulation, natural pregnancy can be attempted. Glucocorticoids play a crucial role in improving pregnancy outcomes, but their use needs to be individualized.

Objective:To investigate the clinical efficacy and safety of a modified injection technique for improving temporal concavity deformities.Methods:A prospective study was conducted on 157 female patients who underwent temporal concavity augmentation at the Department of Plastic Surgery, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences, from June 2019 to June 2022. The patients were aged from 32 to 48 (38.2±3.1) years. Granular fat was obtained through liposuction and purification. Using the midpoint of the frontotemporal line as the entry point, the granular fat tissue was injected evenly at multiple points under the skin and superficial temporal fascia. Additional granular fat was injected in the temporal edge area to ensure a smooth appearance. The visual analogue scale (VAS) was used to assess the patients' intraoperative pain levels. Follow-up visits were conducted for one year postoperatively to assess patient satisfaction with the improvement in temporal concavity, local pigmentation, and fine lines in the lateral orbital area based on preoperative and postoperative photographs. Complications, including swelling, ecchymosis, hematoma, fat embolism, infection, fat liquefaction, and subcutaneous induration, were recorded immediately after surgery and at the one-year follow-up.Results:All the 157 patients experienced mild swelling in the injection area postoperatively, which resolved within 3 to 6 days. Ecchymosis occurred in 15 patients and spontaneously resolved within 10 days. Eleven patients had asymmetry in the filled area, with 3 recovering after local massage and observation, and the remaining 8 undergoing a second fat grafting procedure. A total of 25 patients underwent more than two fat grafting procedures, including 4 who underwent three procedures. Mild local hematoma occurred in 3 patients postoperatively. The intraoperative pain VAS was (1.8±0.5) score. After treatment, the improvement scores for temporal concavity, local pigmentation, and fine lines in the lateral orbital area were (7.4±0.7), (6.8±0.7), and (7.9±0.7) scores, respectively. After one year of follow-up, no complications such as fat embolism, infection, fat liquefaction, or subcutaneous induration were observed in the 157 patients.Conclusion:The modified injection technique for improving temporal concavity deformities is safe and effective, with high patient satisfaction.

Objective:To explore the clinical effects of free bilateral turbocharged anterolateral thigh flaps in tandem in repairing extensive wounds in the foot and ankle.Methods:The study was a retrospective observational study. From April 2020 to June 2023, 12 patients with extensive wounds in the foot and ankle who met the inclusion criteria were admitted to the Department of Wound Repair Surgery of Suzhou Ruihua Orthopedic Hospital, including 8 males and 4 females, aged 21 to 65 years. The wound area after debridement ranged from 27 cm×14 cm to 37 cm×20 cm. The bilateral perforator flaps pedicled with either oblique or descending branches of the lateral circumflex femoral artery were designed and harvested based on the size and shape of the wounds. The individual flap incision area ranged from 16 cm×9 cm to 34 cm×12 cm. The non-homologous perforator of the flap on the one side was turbocharged by anastomosing it with the gross muscular branch or main vessel of the oblique or descending branch of the lateral circumflex femoral artery from the flap. Subsequently, the proximal end of the oblique or descending branch of the lateral circumflex femoral artery and its accompanying vein from the flap on the one side were connected end-to-end with either the anterior tibial artery and vein, posterior tibial artery and vein, or dorsal foot artery and vein in the recipient area, the distal end of the oblique or descending branch of the lateral circumflex femoral artery and its accompanying vein from the flap on the one side were anastomosed end-to-end with a source vessel originating from flap on the other side. The wounds in the flap donor areas were sutured directly. The number and source of perforators carried by the flaps and the duration of the flap repair surgery were recorded. The survival of the flap, the occurrence of vascular crisis, and the wound healing at both donor and recipient areas were observed after surgery. The flap condition, appearance and function of the affected limb were observed during follow-up. At the last follow-up, the sensory function of the flap was assessed using the British Medical Research Council's sensory rating standard, the foot and ankle function of the affected limb was evaluated according to the American Orthopedic Foot and Ankle Society scoring standard.Results:A total 24 flaps were successfully harvested, carrying 60 perforators, including 34 perforators from the oblique branch of the lateral circumflex femoral artery, 24 perforators from the descending branch of the lateral circumflex femoral artery, one perforator from the transverse branch of the lateral circumflex femoral artery, and one perforator from the direct branch of the femoral artery. The duration of the flap repair surgery ranged from 4.2 to 9.0 hours. The flaps of 12 patients exhibited complete survival after surgery. A total of two flaps of two patients experienced venous crisis after surgery but survived through emergency exploration. One patient encountered undesirable wound healing at the donor area of flap on the one side after surgery, which healed after dressing change, debridement, and suturing. The remaining patients' donor area wounds healed. Two patients displayed impaired wound healing in the recipient area, which improved after dressing change and resection of residual sequestrum, and the wounds in the recipient area of other patients healed successfully. During the follow-up of 4-26 months, the flaps demonstrated favorable color and texture, slight edematous appearance, and partial sensory recovery, as well as good aesthetic and functional restoration of the affected limbs. At the last follow-up, the sensory function of the flap was assessed as grade S2 in 9 cases and grade S3 in 3 cases; the foot and ankle function of the affected limb was evaluated as excellent in two cases, good in 9 cases, and fair in one case.Conclusions:The bilateral turbocharged anterolateral thigh flaps have numerous sources of perforators. By implementing supercharging of non-homologous perforators within the flap, the vascular supply to the flap is turbocharged, thereby mitigating the risk of extensive flap necrosis. The flap is an effective approach for repairing extensive wounds in the foot and ankle, resulting in improved function of the affected limb after repair.

The clinical data of 5 patients with occupational contact dermatitis caused by methyl chlorobutyrate treated in the Affiliated Hospital of Jining Medical College and Mamiao Township Hospital of Jinxiang County from September to October 2021 were retrospectively analyzed. Patients were all males aged 33-47 years with a history of exposure to methyl chlorobutyrate 1 to 4 d before the onset of symptoms. Three patients were hospitalized and 2 patients were treated in outpatient clinic. The clinical manifestations were erythema on the trunk or extremities of varying degrees, scattered with blisters and bullae of different sizes, with thin and clear blisters, local ulceration and exudation; no erosion or ulceration was found in the oral cavity and vulva. All 5 patients had elevated white blood cell counts, and 2 patients had abnormal liver function. All patients received symptomatic treatment with topical drugs. Three hospitalized patients were given methylprednisolone and loratadine; in addition, 1 case also received human immunoglobulin and moxifloxacin hydrochloride injection and 2 cases received hepatoprotective drugs. Two outpatients were given prednisone acetate and loratadine for treatment. Three hospitalized patients were all improved and discharged after 14-30 d of treatment. The rash of 2 outpatients subsided after 14 d of treatment, and there was no recurrence after 1-month follow-up. The occupational contact dermatitis caused by methyl chlorobutyrate is primary irritant contact dermatitis, often manifested as erythema and blisters on the trunk or limbs, and timely anti-allergic treatment can effectively control the disease.

Objective:To explore the feasibility of an "ABC" three line perforator locating method in design and harvest of free anterolateral perforator flap of calf.Methods:Between March 2021 and November 2021, 42 patients with 62 wounds on hand and foot were treated in the Department of Hand Surgery, Suzhou Ruihua Orthopaedic Hospital. The "ABC" three line perforator locating method was applied to determine the location and source of perforating branch before operation and to guide the design and harvest of flap during operation in wound reconstruction. Among the 42 patients, 24 had the injury of single digit, 7 had the injuries with 2 digits, 4 with 3 digits, 1 with 4 digits, 1 of the first web, 1 in the wrist, 2 of the great toe, 1 of second toe and 1 in dorsal foot. The sizes of soft tissue defect were 1.5 cm×2.0 cm-3.0 cm×14.0 cm. The sizes of the flaps were 2.0 cm×2.5 cm-3.5 cm×15.0 cm. All donor sites were sutured directly. In the follow-up, sensations of flaps were evaluated following the sensory function evaluation standard of British Medical Research Council(BMRC), and the recovery of the donor and recipient sites was evaluated by the flap comprehensive evaluation scale. Regular follow-up were scheduled at outpatient clinic.Results:A total of 162 perforators were located before operation. There were 95 perforating branches being explored in the operation, of which 5 patients had 1 extra perforating branch than that located before surgery. Seventy-six perforating branches were found consistent with preoperative localisation, with a coincidence rate of 84.4%(76/90). Sixty-four perforating branches were found consistent with the preoperative source with an accuracy rate of 84.2%(64/76). All the 62 flaps survived without a vascular compromise. Follow-up lasted for 6-10(mean 7.1) months. The colour and texture of the flaps were excellent. The flaps were thin and wear-resistant. The sensory function of the flaps was evaluated at S 1-S 3 by BMRC. Comprehensive evaluation scale of flap was excellent in 38 patients and good in 4 patients. Conclusion:"ABC" three line perforator locating method in design of free anterolateral calf flap is a feasible and an ideal auxiliary method in surgical practice. It combines anatomical knowledge, clinical experience and Doppler ultrasound localisation as well as accurately guides the location and source prediction of perforator before surgery.

Objective:To investigate the curative effects of the superficial peroneal artery perforator flap carrying two and more homologous perforators in repairing hand and foot wounds.Methods:A retrospective observational study was conducted. From January to September 2021, 23 patients with hand and foot wounds combined with bone or tendon exposure who met the inclusion criteria were admitted to Suzhou Ruihua Orthopaedic Hospital, including 16 males and 7 females, aged 23 to 68 years. After expansion of the wound, the wound area was 3.0 cm×2.0 cm to 11.0 cm×4.0 cm. All the wounds were repaired with the superficial peroneal artery perforator flap carrying two and more homologous perforators. The area of the resected flap was 4.0 cm×2.0 cm to 12.0 cm×5.0 cm. All the wounds in donor areas were sutured directly. During the operation, the resection of the flap, the number and caliber of carried perforators, the caliber of superficial peroneal artery, the length of vascular pedicle, and the number of accompanying veins of the superficial peroneal artery were recorded. The survival of the flap, the occurrence of complications, and the wound healing in the donor area were observed after operation. The recovery of the donor and recipient areas was followed up. At the last follow-up, the comprehensive evaluation scale was used to evaluate the curative effect of flap repair, and the sensory grading scale was used to evaluate the sensory function of the recipient area.Results:Totally 24 flaps were successfully resected in surgical operations, carrying 56 superficial peroneal artery perforators in total, with the caliber of perforators of 0.20-0.70 mm. The calibers of all perforators carried by 7 flaps were smaller than 0.40 mm. Nineteen flaps carried 2 perforators each, 3 flaps carried 3 perforators each, 1 flap carried 4 perforators, and 1 flap carried 5 perforators. During the operation, the superficial peroneal artery was resected with a caliber of 0.40-1.50 mm, the vascular pedicle was 2-6 cm in length, and each superficial peroneal artery had two accompanying veins. After operation, all the flaps survived smoothly, no vascular crisis or distal necrosis occurred, and the wounds healed well in the donor area. During the follow-up of 6 to 10 months after operation, the color, texture, and elasticity of the recipient area were good. Among them, 6 recipient areas were thinned and reshaped because of bloating. There was only linear scar and no obvious scar hyperplasia or pigmentation in the donor area, without significant change in sensory or motor function. At the last follow-up, the curative effect evaluation of flap repair was excellent in 22 flaps and good in 2 flaps, and the sensory function evaluation of the recipient area was grade S 3 in 1 area and grade S 2 in 23 areas. Conclusions:The superficial peroneal artery perforator flap with two and more homologous perforators has sufficient and reliable blood supply and is effective in repairing hand and foot wounds. It provides an ideal solution for the clinical problem in which the original operation scheme is abandoned due to the existence of only multiple slender perforators of caliber smaller than 0.40 mm, and only a single perforator in the operative field that cannot satisfy the needs of the flap blood supply and recipient area.

Objective:To investigate the therapeutic efficacy of bilobated superficial peroneal artery perforator flap in repairing two adjacent wounds of the fingers.Methods:A retrospective observational study was conducted. From January 2021 to January 2022, 15 patients with two adjacent wounds of the fingers who met the inclusion criteria were hospitalized in Suzhou Ruihua Orthopaedic Hospital, including 10 males and 5 females, aged 25 to 51 years. The area of single wound after debridement was from 2.5 cm×2.0 cm to 7.5 cm×2.5 cm. All the wounds were repaired by the bilobated superficial peroneal artery perforator flap from the lower leg. The single lobe area of bilobated flap was from 3.0 cm×2.0 cm to 8.0 cm×3.0 cm. The wounds in all the donor sites were sutured directly. During the operation, the number of resected flaps, the number and type of carried perforators were recorded, and the calibers of perforator and superficial peroneal artery and the length of vascular pedicle were measured. The survival of flap and the wound healing in the donor and recipient sites were recorded after operation. The recovery of donor and recipient sites were recorded during follow-up. At the last follow-up, the repair effect of flap was evaluated by the comprehensive evaluation scale, and the sensory function of flap was evaluated by the sensory function evaluation standard of British Medical Research Association.Results:During the operation, 15 bilobated flaps were successfully resected, carrying 36 superficial peroneal artery perforators, all of which were septocutaneous perforators with the caliber of 0.2-0.8 mm. The caliber of superficial peroneal artery was 0.4-1.1 mm and the length of vascular pedicle was 3-8 cm. After operation, all the flaps survived with no vascular crisis occurred, and the wounds in donor and recipient sites healed well. During the follow-up of 6 to 12 months, the color and texture of flaps were similar to those of normal tissue in the hand and the appearance of flap was good in 10 cases; the other 5 cases underwent the stage Ⅱ flap thinning and plastic surgery 6 months after operation due to the bloated appearance of flaps. There was only linear scar in the donor site of lower leg, with no obvious scar hyperplasia or pigmentation, and there was no obvious adverse effect on the sensation or motor function of the distal limbs in the donor area. At the last follow-up, the repair effect of flap of 15 patients was excellent in 11 cases and good in 4 cases, and the sensory function of the flap was evaluated as grade S 2 in all cases. Conclusions:The bilobated superficial peroneal artery perforator flap has high proportion of septocutaneous perforator, and the blood supply is sufficient and reliable. Using this flap to repair two adjacent wounds of the fingers causes minimal damage to the donor area, only one group of blood vessels is needed to be anastomosed to repair two wounds, the difficulty of microoperation is reduced, and good flap repair effect and sensory function can be obtained.
