Objective: To share the experience of tissue expansion. Study Design: Descriptive. Duration: June 2005 to May 2009. Setting: Aesthetic Plastic Surgery, Rawalpindi. Inclusion Criteria: Patients of all ages and sex undergoing tissue expansion. Exclusion Criteria: Patients having acute injuries, burns and defects which were closed primarily. Patients undergoing primarily flap surgery. Materials and Methods: The shape and size of the tissue expander was chosen according to the deformity and expected wound geometry. All the surgerieswere performed under general anaesthesia. Drains were removed after 48 – 72 hours. Slightly filled (20 – 50ml) tissue expanders were used. Tissue expansion was started after 7 – 12 days and were filled twice weekly. Results: Total 19 patients (12 males & 7 females) were included in the study. The mean age in males was 32.9 years (range 13 – 44 years) and 21.1 years (range 19 – 36 years) in females. The differentdeformities included contractures 31.6%, Postburn scar 21.1%, hypertrophic scar 15.8% followed by congenital naevus 10.5%. The fill volume ranged from a 140 ml to 480 ml over a period of 8–13 weeks. No major complication was noted. Slight loss of distal flap occurred in 2 patients. No infection/rupture of tissue expander was seen. Conclusion: Tissue expansion is a safe technique for reconstruction of defects, with an obvious advantage of the availability of the adjacent skin.

Although skin- or nipple-sparing mastectomy has been popular in the treatment of breast cancer, the radical excision of breast tissue is unavoidable in certain circumstances. However, the ability of an acellular dermal matrix (ADM) to expand remains questionable, and this situation may further hinder tissue expansion. From October 2017 to January 2020, patients who underwent immediate breast reconstruction with tissue expander placement using ADM whose initial fill volume was less than 50 mL were retrospectively reviewed. The primary outcomes were the number of visits and number of days required to complete the expansion, and the secondary outcomes were the amount of postoperative expansions, expander fill ratio and expander volume. Between the prepectoral group (n = 26) and subpectoral group (n = 39), the mean number of days (81.46 days versus 88.64 days, p = 0.365) and mean number of visits (5.08 versus 5.69, p = 0.91) required to complete expansion exhibited no significant differences. Additionally, there were no significant differences in the mean amount of postoperative expansion (314.23 mL versus 315.38 mL, p = 0.950), the mean final volume (353.08 mL versus 339.62 mL, p = 0.481) or the mean final volume ratio (0.89 versus 0.86, p = 0.35) between the two groups. Therefore, we suggest that prepectoral tissue expander placement after conventional mastectomy can be a valid option.

Introduction: We hypothesize that treatment of significant truncal lesions with truncal tissue expanders and subsequent flap surgery in pediatric patients may increase the risk of scoliosis. This study aims to investigate any relationship between tissue expansion (TE) and scoliosis and to compare the prevalence of scoliosis in our tissue expander population to the general population. Methods: Health records of patients who underwent truncal TE at BC Children’s Hospital between 1997 and 2017 were retrospectively reviewed and analyzed. The cross-sectional component of the study consisted of radiological imaging to establish the presence or absence of scoliosis. Results: We identified 28 patients who underwent truncal TE over the study period. Ten had a scoliosis X-ray on their chart or as a part of the study. Three (10.7%) patients were identified as having developed scoliosis after TE. Conclusions: We recommend that pediatric TE patients be made aware of the potential complication of scoliosis and be followed closely in the years during and after their treatment, in order to allow for preventative measures, early diagnosis and early management (if required).

At the start of preelampsia there is a failure of cytotrophoblst invasion into the maternal spiral arteries that will lead to decreased uteroplacetal perfusion which will be followed by the failure of the unit fetoplacenter to get enough oxygen from the room intervillous that ultimately lead to a state of hypoxia in placenta. This will cause the expenditure of TNF-α dan IL-1β from placenta and a factors called hypoxia-inducible transcription factors that will spur the trophoblast to produce activin A lot more. This research was conducted by cross sectional method in maternal room of obstetrics and gynecology department of Central General Hospital of Dr. M. Djamil Padang from August 2015 until February 2016 with 20 patients of severe preeclampsia and 20 patients not severe preeclampsia, who met inclusion criteria and there is no exclusion criteria. Then performed statistical analysis using Mann-Whitney test to determine difference in mean maternal activin A serum levels of severe preeclampsia and not severe preeclampsia. The mean maternal serum levels of activin A in severe preeclampsia is 32,55 ± 1,84 ng/ml and in pregnancy with no severe preeclampsia is 8,59 ± 0,59 ng/ ml. Difference in mean maternal serum level of activin A in the two groups was statistically significant (p=0,001). Ma-ternal serum activin A levels is significantly higher in severe preeclampsia than pregnancy with no severe preeclampsia.Keywords: Activin A, severe preeclampsia, not severe preeclampsia

INTRODUCTION: Tissue expanders have been of great value in plastic surgery. Tissue expansion was developed for a specific indication; however, within a very short time, the concept of tissue expansion found wide applicability. From 1990 to 1999, 315 expanders in 164 patients were utilized. A retrospective analysis of complications and prognostic factors for complications were done. METHODS: The indications for tissue expansion were burns (50%), trauma (32%), and sequelae of previous surgery (8.8%). The expanders were inserted most frequently in the scalp, trunk and neck. RESULTS: There were 22.2% of complications and the most common were expander exposure (50%), infection (24%) and bad function of the expander (12.8%). The present study revealed an increased rate of minor complications in the group of 0 to 10 years of age and an increased rate of major complications for face and neck expansions compared to trunk expansion. There were no increased complication rates for the other age and anatomic site groups, previous expansion, concomitant expansion and type of expander used. CONCLUSIONS: The outcomes from tissue expansion procedures done in our hospital are similar to those reported in the literature. Tissue expansion is a good and safe technique.

Background: Scalp defects managed by local transposition flaps with donor site alopecia are aesthetically not acceptable to patients. Scalp expansion with tissue expanders is needed for proper correction of this deformity.Methods: Authors retrospectively reviewed all cases of post traumatic and post burn scalp defects that were managed initially by local transposition flap and later by scalp expansion by tissue expanders at our institute over a period of 5 years and conducted an outcome survey. Authors’ institutional protocol in such patients and results of the review are presented.Results: Twenty-eight patients were included in the study. Eight patients had post traumatic and 20 cases had post electric burn scalp defect. The mean age of patients was 28.92±8.26 years. Thirty-eight tissue expanders of various sizes (200-600 ml) were used in 28 patients. The mean follow-up time was 9.07±1.92 months. Major complication rate in present study was 2.63%. Results of outcome survey revealed more than 90% patients were satisfied after third surgery.Conclusions: Scalp transposition flap donor site alopecia can be easily corrected by tissue expansion. The complications are not severe and can be managed easily. It should be offered to all such types of patients, as it leads to proper social rehabilitation and satisfaction among these groups of patients.

Objectives. To investigate whether the incidence of acute appendicitis increases in summer and whether complicated cases present more in summer. Methods. A single-center cross-sectional, retrospective study on 697 cases of appendicitis admitted in the year 2018. Inclusion criteria: patients admitted with acute appendicitis who underwent appendectomy of all ages. Exclusion criteria: conservative management. Analysis was performed using Microsoft Excel. Pearson correlation coefficient was calculated to assess the correlation between monthly incidence of appendicitis and mean temperature in that month. Results. Fifty-one patients who were managed conservatively were excluded. Accordingly, 646 patients were included. Ages ranged from three to 77 years. Males comprised the majority (500, 77.4%). Gangrenous, perforated, and purulent appendices were regarded as complicated appendicitis. The highest number of cases were admitted in summer (234), comprising 36.2% of cases. Complicated cases were equal to 65, of which 23 (35.4%) were admitted in summer and 30 (46.2%) in winter. The highest number of cases was during the month of July (68), while the lowest (40) was during February. This corresponded to the highest recorded mean temperature (36.2°C) and second lowest (19.8°C), respectively. Moderate positive correlation (Pearson’s R 0.5183) between the monthly incidence of appendicitis and the mean temperature is noted. Conclusion. More cases of appendicitis were noted during summer. Monthly incidence correlated positively with the temperature. Larger numbers over several years are needed to draw better conclusions and reach the possible causes behind such variation.

The Risk Malignancy Index (RMI) is one of the simplest assessments that can assist in diagnosing and determining the prognosis of benign and malignant adnexa masses. Epithelial carcinoma is the most common type of about 90% of ovarian cancers.  As many as 35-40% of the epithelial type are serous and 6-10% are musinosum.This study aims to compare the picture of RMI value on the incidence of ovarian cancer serosum and musinosum type. This study was cross sectinal comparative study from medical records of ovarian cancer patients at obstetrics and gynecology section in DR M Djamil Hospital Padang from January 1st, 2017 until December 31st, 2017. The population was found one hundred and forty of patients with ovarian cancer and only one hundred and twenty nine of patients met the inclusion criteria and there were no exclusion criteria. Next RMI value is calculated based on RMI 1 formula, result is described in tabular form and data processing with SPSS program. Conclucion of this study is there were no differences in age distribution, ascites occurrence and age of menopause in serous and musinosum ovarian cancer. There is a difference in Ca, 125 levels in serous with musinosum ovarian cancer which also contribute to the high value of RMI. The mean value of patients‘s RMI in serous type ovarian cancer is higher than the mean value of RMI in patients with type Musinosum ovarian cancer.

A Prospective Study

Tissue expansion, is a simple method of breast reconstruction. Method. A prospective study of 27 patients treated over a 43 month period is described. At the first stage the expander is inserted in the dual plane, and the medial pectoral nerve is divided. The tissue expander is over-expanded. Second stage: a de-epithelialized vertical triangle is used to aid anterior projection, an inframammary fold is created and a silicone gel prosthesis inserted. Z-plasties are added to the transverse scar. The contralateral breast can be treated or left alone. Complications were recorded and the results were assessed by 4 plastic surgeons using a visual analogue scale. Results. 19 patients had expanders inserted at mastectomy (2 bilateral) and 8 underwent delayed reconstruction, with a mean age of 47 years (range 30–65 years). A single prosthesis was inserted in 15 patients (mean size 320 mL) and two prosthesis were stacked in 12 patients (mean volume of 400 mL). The mean delay from full expansion to the second stage was 10 weeks (range 3 weeks–11 months). A contralateral augmentation was performed in 5 patients, pexy in 10, a reduction in 2 and in 8 patients no procedure was performed. One patient required explantation. The mean visual analogue assessment was 7. Conclusion. This technique should be considered enhance the cosmetic results in tissue expansion.

Background This study evaluated the Blossom system, an innovative self-filling, rate-controlled, pressure-responsive saline tissue expander (TE) system. We investigated the feasibility of utilizing this technology to facilitate implant-based and combined flap with implant-based breast reconstruction in comparison to conventional tissue expansion.Methods In this prospective, single-center, single-surgeon pilot study, participants underwent either implant-based breast reconstruction or a combination of autologous flap and implantbased breast reconstruction. Outcome measures included time to full expansion, complications, total expansion volume, and pain scores.Results Fourteen patients (TEs; n=22), were included in this study. The mean time to full expansion was 13.4 days (standard error of the mean [SEM], 1.3 days) in the combination group and 11.7 days (SEM, 1.4 days) in the implant group (P=0.78). The overall major complication rate was 4.5% (n=1). No statistically significant differences were found in the complication rate between the combination group and the implant group. The maximum patient-reported pain scores during the expansion process were low, but were significantly higher in the combination group (mean, 2.00±0.09) than in the implant group (mean, 0.29±0.25; P=0.005).Conclusions The reported average duration for conventional subcutaneous TE expansion is 79.4 days, but this pilot study using the Blossom system achieved an average expansion duration of less than 14 days in both groups. The Blossom system may accommodate single-stage breast reconstruction. The overall complication rate of this study was 4.5%, which is promising compared to the reported complication rates of two-stage breast reconstruction with TEs (20%–45%).
