Application of 3D printing technology in brachytherapy for vaginal stump tumor after CT-guided cervical carcinoma surgery

Objective To investigate the application of 3D printing technology in the manufacture of individualized source applicator for intraluminal brachytherapy. Methods A retrospective analysis was performed for the clinical data of one patient with vaginal stump stenosis and regular solid tumor after cervical carcinoma surgery. The gauze soaked in the developer was used for vaginal packing, and then CT scan was performed to obtain the three-dimensional intraluminal geometric outline of the vagina. A software was used to extract the outline, and 3 lumens were reserved near the lesion. The 3D printer and medical silica gel were used to manufacture the source applicator. The source applicator was placed in the vagina, and CT scan was performed to adjust the position of the source applicator. The final CT image was transferred to the planning system for the delineation of target volume and organs at risk and calculate dose distribution. Results The individualized vaginal source applicator manufactured by 3D printing technology fitted well to the target volume, and the curvature of the catheters was greater than 1 cm, so that the radioactive source could pass successfully. The inserted catheters were cut, and the total operative length of the radioactive source was set to be 1 280 mm, which helped to realize the accurate connection between the individualized source applicator and the afterloader. At the same time when the prescribed dose was reached in the lesion, the bladder and rectal D2 cm3 was 320.4 cGy and 331.5 cGy, respectively, which did not exceed the dose limits. Conclusions The individualized source application manufactured by 3D printing technology is applicable to the treatment of patients with vaginal stump stenosis and regular solid tumor after cervical carcinoma surgery, and its clinical effect and adverse effects await further investigation.

Diagnosis and treatment of pharyngostoma and esophagostoma after anterior cervical spine surgery

Objective To investigate the diagnosis, treatment and prevention strategies of pharyngostoma and esophagostoma caused by anterior cervical spine surgery. Methods A retrospective analysis were performed in 17 cases of anterior cervical operation complicated with pharyngeal and esophageal fistula from 1999 March to 2010 June, including 11 male cases and 6 female cases, aged from 7 to 67 years with the mean age of 44.23 years. 16 cases (94%) got inflammation of anterior cervical surgery incision and throat pain. 2 cases (11%) accompanied by high fever, whose body temperature was as high as 39.2° and incision particles or liquid flew after eating. 17 cases underwent upper gastrointestinal radiography, and regular oral methylene blue. Barium overflew from fistula in 2 cases (11%) after upper gastrointestinal tract barium meal angiography, while methylene blue overflew from incision in 7 cases (41%) after oral methylene blue. Through X-ray examination, gas fistula before vertebral was visible in 14 cases (82%). A diagnosis can be made by outflow through fistula after barium esophagography or oral administration of methylene blue. For unknown but highly suspected pharyngeal and esophageal injury, operation can be confirmed if no improvement of symptoms was found after fasting, nasogastric or parenteral nutrition, and ant-infection treatment for 1 week. Results All of 17 patients underwent surgical treatment. During operation, fistula dot or small irregular shape can be seen in 8 cases; long stripe in 3 cases; boundary not clear or irregular in 2 cases; adhesion around the fistula of anterior cervical fascia, similar to tear in 1 case; two fistula in 1 case; fistula located in pharynx posterior wall or esophageal which was not clear or fistula of unknown reason in 2 cases (fascia might be not at the same side of incision or fascia was small and already closed). Pharynx posterior wall and esophageal fistula was found in 3 cases during surgical exploration, which was immediate sutured and placed with drainage tube. After 7 to 14 days, if flow was less than 30 ml, and no bacterial growth was found in 3 consecutive drainage fluids, we pull out the tube. Patients who underwent nasal feeding for 2 to 3 weeks, and then took liquid diets complained nothing, and cured after 1 month. 12 cases underwent debridement, stitching fistula, irrigation and drainage tube placement instantly. The wash pipe was removed after 12 to 21 days and 3 consecutive drainage fluids showed no bacterial growth. Then 2 to 3 days later the drainage pipe was pull out. Two to three months later these patients healed. 2 cases firstly underwent debridement and suture or part suture, and then the incision was opened and filled with nitrofurazonium gauze tamponade. Gradually pull out the filling gauze and change the dressing of wound. If the residual cavity was large or the drainage was pus, flush the wound with physiological saline once a day, then three times a week, and finally once a week. These patients healed after 6 to 12 months. Pharyngostoma or esophagostoma of all patients was found timely, and active surgical treatment was performed, so no obvious complications was found postoperatively. All 17 patients recovered and resumed diet after 1 to 12 months postoperatively. Conclusion Pharyngeal and esophageal fistula is a rare but severe complication after anterior cervical surgery, which seriously affect the effect of operation and even lead to death. Early diagnosis and active intervention can obtain satisfactory curative effect.

Negative pressure environment promotes angiogenesis and microvessel maturation

Objective To study the effect of negative pressure environment on angiogenesis and microvessel maturation and relevant signaling pathway, and explore the potential mechanisms of angiogenin/tyrosine kinase receptor-2 signal pathway promoting angiogenesis and microvessel maturation under negative pressure environment. Methods Successive 58 patients enrolled in this study were treated with negative pressure or petroleum gauze, and at 1st, 3rd, 7th, and 15th day blood flow perfusion was detected, as well as the Western boltting was applied to detect angiogenin-1 (Ang-1), the phosphorylation of tyrosine kinase receptor-2 (pTie-2), angiogenin-2 (Ang-2), α-smooth muscle actin (α-SMA) and collagen type Ⅳ respectively. Results Negative pressure environment could change the expression of related factorsin the early stages of wound healing (1-3 d) and late stage (7-15 d). In experimental group on day 3, the relative value of Ang-2 was 1.87±0.35 and significantly higher than control group (1.32±0.23, P<0.05), relative value of pTie-2 was 0.36±0.02 and significantly lower than control group (0.87±0.04, P<0.05), relative value of Ang-1 was 0.34±0.02 and significantly lower than control group (0.78±0.07, P<0.05), the ratio of Ang-1/Ang-2 was 0.34±0.02 and significantly lower than the control group (0.78±0.07, P<0.05). In the experimental group on day 15, negative pressure environment leadin to the relative value of Ang-1 was 1.89±0.24 and significantly higher than conrol group (1.35±0.22, P<0.05), relative value of α- smooth muscle actin was 2.56±0.42 and significantly higher than control group (1.68±0.31, P<0.05), relative value of collagen type Ⅳ was 2.32±0.35 and significantly higher than control group (1.36±0.24, P<0.05), the relative value of pTie-2 was 2.12±0.44 and significantly higher than control group (1.23±0.31, P<0.05), the ratio of Ang-1/Ang-2 was 4.86±0.67 and significantly higher than control group (1.87±0.54, P<0.05), the relative value of Ang-2 was 0.36±0.05 and significantly lower than control group (0.71±0.06, P<0.05). Conclusion Negative pressure could preferentially promote microvessel destabilization in the early stage of wound healing, consequently increase the number of angiogenesis. Subsequently, in the later stage of wound healing the negative pressure could preferentially promote microvessel stabilization, and thus promote microvessel maturation through the angiogenin/tyrosine kinase receptor-2 signal pathway. Negative pressure could increase blood flow perfusion because of abundant and mature microvessel pericytes in the wound.

COMPARISON OF THREE METHODS OF WET GAUZE, ADHESIVE TAPE AND EYE OINTMENT TO PREVENT CORNEAL ULCERATION IN PATIENTS UNDERGOING GENERAL ANESTHESIA

Introduction: The main protective reflexes, including eye blinking and tearing impair in the operating room due to anesthesia and receiving sedation, so the eyes of these patients will get susceptible to damage. The aim of this study was to determine the influence of the three eye care methods (blindfolding with adhesive tape, using wet gauze or eye ointment) in preventing dry eye and corneal ulcers in patients under general anesthesia in Jahrom hospitals in 2015. Materials and method: This study is a clinical trial carried out on candidate patients undergoing surgery with general anesthesia who were randomly divided into three groups of 29 individuals. A 22-option checklist including demographic information and the results of findings of dry eye and corneal ulcers was completed by trained nurses and the researcher. The data were analyzed using SPSS software version 17 and Mc Nemar test, T-test, Chi-Square test. Results: The conducted studies showed that of 87 patients, 29 patients (33.33%) were suffering from dry eyes and in total, 12 (13.79%) patients got corneal ulcers including 6 (50%) patients in the adhesive tape group and 3 (25%) patients in the ointment group and 3 (25%) patients in the wet gauze group. Conclusion: Generally speaking, it was determined that there were no significant differences between the three methods of preventing dry eye and corneal ulcers. However, dry eye and corneal ulcers had happened less in the protective method by ointment. Therefore, the use of ointment as a protective way is recommended to prevent dry eyes and corneal ulcers in patients hospitalized in the intensive care unit.

Repair of skin and soft tissue defects around the knee joints combined with patellar ligament defects using free anterolateral thigh flaps with iliotibial tracts

To observe clinical efficacy of using free anterolateral thigh flaps with iliotibial tracts in repairing skin and soft tissue defects around the knee joints with patellar ligament defects. Twelve patients with skin and soft tissue defects around the knee joints and patellar ligament defects were hospitalized from June 2010 to June 2014. The defects of skin and soft tissue ranged from 7 cm × 6 cm to 16 cm × 12 cm in area, and patellar ligament ranged from 5 to 12 cm in length and 2.5 to 4.0 cm in width. Free anterolateral thigh flaps with iliotibial tracts were used to repair these defects. During reconstruction of patellar ligament, both ends of iliotibial tract were successively folded to form tendon-like three-layer structure at first, and then the newly formed structure was wrapped around the broken ends of patellar ligament and fixed with suture. The flap size ranged from 9 cm × 8 cm to 18 cm × 14 cm. The iliotibial tract ranged from 7 to 14 cm in length and 8 to 12 cm in width. The donor sites were closed by grafting with autologous split-thickness skin harvested from thigh or trunk, and parked with gauze. Immediately after operation, the knee joints were fixed in extension with orthosis for 6 weeks. Weight bearing training of affected limbs being kept in extension position was started from 2 weeks after operation, and flexion and extension exercise of affected knee joints was begun from 6 weeks after operation. Before operation and 12 months after operation, the degree of pain around the knee joints and knee joint function were evaluated with the international knee documentation committee knee uation form, and the ranges of flexion and extension of knee joints were also evaluated. The integrity of reconstructed patellar ligament was assessed by color Doppler ultrasound from 6 to 12 months after operation. The occurrence of surgery-related complications was observed in all patients within 12 months after operation. (1) After operation, all flaps survived well, and all wounds healed well. (2) The average score of pain around the knee joint was increased from 31 points before operation to 77 points in 12 months after operation. The average score of knee joint function was increased from 14 points before operation to 65 points in 12 months after operation. Before operation, the average ranges of flexion and extension of knee joint were respectively 89° and 65°, and they were respectively increased to 130° and decreased to 15° in 12 months after operation. From 6 to 12 months after operation, color Doppler ultrasound showed that the condition of reconstructive patellar ligaments in all patients was good without the need for further surgical intervention; the superficial sensation of the flaps was recovered in different degrees. No surgery-related complication was observed in all patients within 12 months after operation. Free grafting of anterolateral thigh flap with iliotibial tract is an effective and reliable method for repairing skin and soft tissue defects around the knee joints combined with patellar ligament defects, and the surgical procedure can recover function and appearance of knee joint satisfactorily.

Methods Water absorption, dehydration, and permeability rate of gauze (A), modified- chitosan non- woven fabric composited with beewax- sesameoil(B), modified- chitosan sponge(C),and modified- chitosan spong dressing composited with beewax- sesameoil(D)were measured, and water absorption rate and water vapor transmission rate(WVTR) were calculated.Two full- thickness skin wounds were created on the back of the 12 SD rats each bilaterally and symmetrically, and were divided into two groups randomly, the first group on the left provides wound rats in group A(NSgauze group), the right of the wound for group B(modified- chitosan non- woven fabric composited with beewax- sesameoil group), the left side of the wound for the second group of rats in group C(modified- chitosan sponge group), the right of the wound for D group(modified- Chitosan spong dressing composited with beewaxsesameoil group).After dressing process modeling conducted every two days, the wound healing rate and CD31 expression with the first,7th,14th,21th day. Results Modified- Chitosan spong dressing composited with beewax- sesameoil showed a water absorption 111% of its own weight.Its water absorption rate and loss rate is stable and lasting; Water vapor transmission rate(WVTR)is 1 080.82 g/(m2·d).Its moisture resistance is good,but its breathability is unsatisfactory.The wound healing rate of group D was(80.99±3.06)%, (97.59±1.00)% at 14th, 21th day.There was significant difference with other groups.At 14th and 21th days, the wound healing rate of group D were better than other groups.There were no significant differences in capillary density between group D and B, C group at 7th day.At 14th and 21th days, the capillary density of group D were significant differences with other groups. Conclusion Modified- chitosan spong dressing composited with beewax- sesameoil with good moisture resistance, can promote wound healing and wound tissue expression of CD31,is conducive to the growth of new blood vessels wounds.
