Clinical report of microsurgical treatment of Kohler's disease.

The conservative treatment for Kohler's disease will take several months, but some patients still have flatfoot and persistent pain. From October 2013 to July 2015, 3 children with Kohler's disease underwent navicular decompression and micro-circulation reconstruction surgery in our hospital. All the patients have received conservative treatment for more than 3 months and the effect was poor. X-ray showed the bone density of navicular increased significantly. All patients were followed up over 1 year. The 3 patients recovered well. VAS score decreased from 7.0 to 2.6 at 1 month after the operation. The pain symptom disappeared completely on 3 months after surgery. The density of navicular bone recovered to normal. Navicular decompression and micro-circulation reconstruction surgery may quickly improve the ischemic status of navicular bone, alleviate pain symptom and enable patients to resume normal activity as soon as possible.

Patient satisfaction after lower limb replantation surgery for traumatic amputation - a qualitative study.

BACKGROUND: The majority of published literature clinically assesses surgical outcomes after lower limb replantation for traumatic amputations. However, patients' satisfaction and quality of life may not be accurately measured through rigid scoring using standardized patient reported outcome measures. PURPOSE: The aim of this study was to qualitatively assess patient satisfaction and factors associated with achieving good outcomes after successful lower limb replantation surgery. METHODS: A semi-structured interview was conducted with 12 patients who underwent lower limb replantation surgery following traumatic amputation injuries. The interview focused on the patients' experience and satisfaction throughout their injury, surgical journey, rehabilitation and reintegration into their communities. An inductive and deductive thematic analysis was applied using the recorded transcripts to evaluate the overall satisfaction of the patients after lower limb replantation surgery. RESULTS: The following observations emerged from the structured themes among all the patients interviewed: (1) Family and social support was significantly associated with improved qualities of life and satisfaction after lower limb replantation; (2) Patients were generally satisfied with their outcomes despite limitations in physical capabilities; (3) Satisfaction was associated with acceptance of their cosmetic deformity; (4) Social integration and being able to participate in a meaningful manner was associated with greater satisfaction after recovery. CONCLUSIONS: Patients who undergo lower limb replantation can have a significantly improved quality of life if they have strong social support, are able to contribute in a meaningful manner to their communities after surgery, and are accepting of their cosmetic deficiencies.

Long-term outcomes of toe replantation: A review of ten cases.

BACKGROUND: Foot injuries due to vehicular or other accidents are common. However, complete toe amputation is rare. This study explored the current protocols and clinical significance of toe replantation. METHODS: From December 2011 to December 2018, ten patients with 13 severed toes underwent toe replantation in our hospital. Seven cases were replanted antegrade, and three cases were replanted retrograde. RESULTS: All patients were followed for two to three years after toe replantation. One big toe underwent necrosis, while the other 12 toes survived completely. The appearance and feel of the successfully replanted toes were satisfactory, and the patients exhibited a normal gait. CONCLUSION: Toe replantation can achieve an acceptable appearance and function of the foot and considerably reduce the psychological effects experienced by the patients. Increased clinical attention and application of toe replantation are needed. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Application of cryopreserved autologous skin replantation in the treatment of degloving injury of limbs.

Degloving injury is a common and intractable injury with the bone and tendon exposed and contamination, the stripped skin cannot be replanted immediately and will be discarded, although auto-graft is needed for subsequent wound repair. In this study, autologous skin cryopreservation technique was applied to the treatment of severe limb degloving injuries. The clinical data of 9 patients from January 2016 to December 2018 were analyzed retrospectively. Among the 9 cases, 1 case developed necrosis due to wound infection, and the rest survived 60-100%. The replanted cryopreserved skin were soft and resilient, with poor sensory recovery, varying degrees of discoloration and no hair growth. Cryopreservation provides more time for improving the wound and whole-body condition. The frozen skin had good quality and high survival rate. Our study can effectively use the degloving skin, reduce the damage of the donor area.

Molecular Characteristics of Staphylococcus aureus From Food Samples and Food Poisoning Outbreaks in Shijiazhuang, China.

As an opportunistic pathogen worldwide, Staphylococcus aureus can cause food poisoning and human infections. This study investigated the sequence typing, the penicillin (blaZ) and methicillin (mec) resistance profiles of S. aureus from food samples and food poisoning outbreaks in Shijiazhuang City, and the staphylococcal enterotoxin (SE) types of the S. aureus isolates from food poisoning. A total of 138 foodborne S. aureus isolates were distributed into 8 clonal complexes (CCs) and 12 singletons. CC1, CC5, CC8, CC15, CC97, CC59, CC398, CC88, and CC7 were the predominant CCs of foodborne S. aureus isolates. Moreover, CC59, CC15, and CC5 were the most prevalent CCs in food poisoning outbreaks. SEE was the most commonly detected SE in food poisoning isolates. One hundred thirty-three S. aureus isolates harbored the penicillin-resistant gene blaZ, and nine isolates carried the mec gene. The present study further explained the relationship between S. aureus and foods and food poisoning and indicated the potential risk of S. aureus infection.

Three-dimension correction of Charcot ankle deformity with a titanium implant.

BACKGROUND: Charcot neuroarthropathy of the ankle is an extremely challenging clinical dilemma, and its surgical management can be highly complicated. The goal of Charcot ankle treatment is to to restore a plantigrade and stable foot, and thus to avoid ulceration with subsequent infection. This report aims to introduce a method of correcting ankle deformity using a novel 3D printing technique. PATIENT AND METHODS: One patient with Charcot ankle deformity was operated in this study. The ankle deformity of this patient was quantified in three dimensions through computed tomography. On the basis of the computed tomography scans, a new titanium implant was designed and manufactured using 3D printing. The implant was applied in the surgery of tibio-talo-calcaneal arthrodesis to restore local anatomy of the affected ankle of the patient with Charcot neuroarthropathy. RESULTS: Evaluation of the post-operative radiography indicated union in the affected ankle. After surgery, the planar foot in this patient was restored. The patient was satisfied with the post-operative course, and joint fusion was successful as indicated by 2-year post-operative evaluation. The results of post-operative follow-up showed that the lower limb length of the patient with Charcot neuroarthropathy was salvaged, and the patient retained the plantigrade foot. CONCLUSION: Three-dimensional printing technique combined with tibio-talo-calcaneal arthrodesis may help to correct ankle deformity in patients with Charcot neuroarthropathy.

Cryopreservation and transplantation of amputated finger.

Every year tens of millions reconstruction surgeries were performed to repair tissue defects caused by trauma or malignant tumor. As the composite tissues are very difficult to be preserved for a long time in vitro, "organ bank" was proposed. In addition to immune rejection, tissue cryopreservation is the key step of the "Organ Bank". In this study, two severed fingers were cryopreserved because the patients' conditions were not allowed to undergo the replantation immediately. The fingers were perfused with the cryopreservation solution through the digital artery at a speed of 1 ml/min, they were frozen following a control rate freezing procedure and stored in the liquid nitrogen. One finger was cryopreserved for 10 days and the other for 30 days. Both fingers were successfully replanted when the patient get better. After 1 year follow-up, the replanted fingers achieved satisfactory appearance and function. Our result demonstrate small composite tissues such as severed fingers can be cryopreserved and replanted successfully, which will help the patients who cannot receive the replantation immediately. This method will have important application value in cryobiology and clinical medicine.

Recombinant human growth hormone treatment of mice suppresses inflammation and apoptosis caused by skin flap ischemia-reperfusion injury.

BACKGROUND: This study was to investigate the effects of recombinant human growth hormone (rhGh) on ischemia-reperfusion (I/R) injury of mouse flaps. METHODS: Healthy mice were randomly divided into four groups as follows: sham group, the IR group, the sham+rhGH group and the IR+rhGH group, with 12 mice in each group. Skin pathology was tested by hematoxylin and eosin staining. The flap survival of each group was measured after 7 days. The levels of superoxide dismutase (SOD) and malondialdehyde (MDA) were determined using corresponding kit. The levels of interleukin (IL)-6 and tumor necrosis factor (TNF)-α in serum and flap were respectively measured by performing enzyme-linked immunosorbent assay and quantitative real-time (qRT)-PCR. The expressions of cleaved caspase-3, B cell lymphoma/leukemia-2 (Bcl-2), Bcl-2-associated X protein (Bax), vascular endothelial growth factor (VEGF), MnSOD, toll-like receptor 4 (TLR4), and galectin-3 and (p)-p65 were analyzed by RT-PCR or/and Western blot. RESULTS: Prophylactic systemic application of recombinant human GH reduced the pathological damage of skin IR and significantly improved the flap survival of IR in mice, accompanied by elevation of VEGF. After administration of recombinant human GH, the activity of SOD/MnSOD in the flap was significantly increased, while the content of MDA was decreased. Cleaved caspase-3 and Bax were downregulated and Bcl-2 was upregulated in IR+rhGH group, compared to IR group. The levels of TLR4, Galectin-3 and p-p65 were decreased by rhGH. CONCLUSION: rhGH had protective effects on flap IR injury, and can be used as a drug intervention target for the treatment of skin flap IR injury.

Application of Aidi injection (艾迪注射液) in the bronchial artery infused neo-adjuvant chemotherapy for stage III A non-small cell lung cancer before surgical operation.

OBJECTIVE: To study the effect of Aidi Injection (艾迪注射液,ADI) applied in the bronchial artery, applied in the bronchial artery infused (BAI) neo-adjuvant chemotherapy for stage III A non-small cell lung cancer (NSCLC) before surgical operation. METHODS: The 60 patients with NSCLC stage III A underwent two courses BAI chemotherapy before tumor incision were assigned to two groups, the treatment and the control groups, using a random number table, 30 in each group. ADI (100 mL) was given to the patients in the treatment group by adding into 500 mL of 5% glucose injection for intravenous dripping once daily, starting from 3 days before each course of chemotherapy, and it lasted for 14 successive days, so a total of 28 days of administration was completed. The therapeutic effectiveness and the adverse reaction that occurred were observed, and the levels of T-lymphocyte subsets, natural killer cell activity, and interleukin-2 in peripheral blood were measured before and after the treatment. RESULTS: The effective rate in the treatment group was higher than that in the control group (70.0% vs. 56.7%, P<0.05). Moreover, as compared with the control group, the adverse reaction that occurred in the treatment group was less and mild, especially in terms of bone marrow suppression and liver function damage (P<0.05). Cellular immune function was suppressed in NSCLC patients, but after treatment, it ameliorated significantly in the treatment group, showing significant difference as compared with that in the control group (P<0.05). CONCLUSION: ADI was an ideal auxiliary drug for the patients in stage III A NSCLC received BAI neo-chemotherapy before surgical operation; it could enhance the effectiveness of chemotherapy, ameliorate the adverse reaction and elevate patients' cellular immune function; therefore, it is worthy for spreading in clinical practice.
