Zauki NAM, Satyanarayana B, Fairuz-Fozi N, Nelson BR, Martin MB, Akbar-John B, et al.

Data Brief, 2019 Feb;22:458-463.
PMID: 30619923 DOI: 10.1016/j.dib.2018.12.027

The data available in this repository were gathered from Balok, the only most productive spawning site for horseshoe crabs Tachypleus gigas and Carcinoscorpius rotundicauda in East Coast of Peninsular Malaysia. The mangrove horseshoe crab, C. rotundicauda population and spawning data are available in the first table. The horseshoe crabs were retrieved from Balok River using 11.43 cm mesh size gill nets installed at the river mouth, the confluence and last meander. The arthropods were inspected for damage, abnormality and growth before their release into Balok River, particularly at the site of capture. Sediment samples were retrieved at their spawning grounds to ascertain sediment composition and size classifications which were also processed using Logarithmic Method of Moments. Water parameters like temperature, pH and salinity were also investigated during year 2016. All these information are compiled into the second table and arranged according to the period of data availability. The horseshoe crab catch data of years 2012, 2013, 2014, 2015 and 2016 were made available by artisanal fisher and compiled in the third and fourth table for inter-species comparison.

Single incision laparoscopic surgery (SILS) inguinal hernia repair - recent clinical experiences of this novel technique

Yussra Y, Sutton PA, Kosai NR, Razman J, Mishra RK, Harunarashid H, et al.

Clin Ter, 2013;164(5):425-8.
PMID: 24217830 DOI: 10.7417/CT.2013.1608

Inguinal hernia remains the most commonly encountered surgical problem. Various methods of repair have been described, and the most suitable one debated. Single port access (SPA) surgery is a rapidly evolving field, and has the advantage of affording 'scarless' surgery. Single incision laparoscopic surgery (SILS) for inguinal hernia repair is seen to be feasible in both total extraperitoneal (TEP) and transabdominal pre-peritoneal (TAPP) approaches. Data and peri-operative information on both of these however are limited. We aimed to review the clinical experience, feasibility and short term complications related to laparoscopic inguinal hernia repair via single port access. A literature search was performed using Google Scholar, Springerlink Library, Highwire Press, Surgical Endoscopy Journal, World Journal of Surgery and Medscape. The following search terms were used: laparoscopic hernia repair, TAPP, TEP, single incision laparoscopic surgery (SILS). Fourteen articles in English language related to SILS inguinal hernia repair were identified. Nine articles were related to TEP repair and the remaining 5 to TAPP. A total of 340 patients were reported within these studies: 294 patients having a TEP repair and 46 a TAPP. Only two cases of recurrence were reported. Various ports have been utilized, including the SILS port, Tri-Port and a custom- made port using conventional laparoscopic instruments. The duration of surgery was 40-100 minutes and the average length of hospital stay was one day. Early outcomes of this novel technique show it to be feasible, safe and with potentially better cosmetic outcome.

Use of the Gynecare Prolift system in surgery for pelvic organ prolapse: 1-year outcome

Vaiyapuri GR, Han HC, Lee LC, Tseng LA, Wong HF

Int Urogynecol J, 2011 Jul;22(7):869-77.
PMID: 21479713 DOI: 10.1007/s00192-011-1400-9

INTRODUCTION AND HYPOTHESIS: This retrospective study reports the 1-year outcome in women who underwent mesh-augmented Prolift surgery performed from 2006 to 2008. There were a total of 254 patients, with 128, 106 and 20 patients receiving total, anterior and posterior Prolift, respectively.
METHODS: Incidence of thigh pain was lower in 2008 compared to 2006 and 2007 (p < 0.0001). The percentage of patients requiring blood transfusions (p = 0.09), duration of IDC ≥ 7 days (p = 0.27), wound dehiscence and re-operation rate were lower in 2008 in contrast to 2006 and 2007 (p = 0.43). Only 209 patients (82.3%) were available for review at 1 year. There were two (1.0%) cases of recurrent vault prolapse.
RESULTS: The subjective and objective cure rates at 1 year after this mesh implant surgery in 2006, 2007 and 2008 were 92.1% and 92.1%; 97.0% and 92.4% and 100% and 97%, respectively. The mesh erosion rate was remarkably lower in 2008 as compared to 2007 and 2006 (p < 0.001).
CONCLUSIONS: This synthetic mesh-augmented implant surgery is effective and safe, and surgical outcome appears related to the learning curve of the surgeon.

Fulltext Successful laparoscopic management of paraesophageal hiatal hernia with upside-down intrathoracic stomach: a case report

Siow SL, Tee SC, Wong CM

J Med Case Rep, 2015;9:49.
PMID: 25890166 DOI: 10.1186/s13256-015-0519-6

Paraesophageal hernia with intrathoracic mesentericoaxial type of gastric volvulus is a rare clinical entity. The rotation occurs because of the idiopathic relaxation of the gastric ligaments and ascent of the stomach adjacent to the oesophagus through the hiatus defect, while the gastroesophageal junction remains in the abdomen. The open approach remains the gold standard therapy for most patients. Here we report the case of a patient with such a condition who underwent a successful laparoscopic surgery. A literature search revealed that this is the first case report from Southeast Asia.

Fulltext Screw Migration into Colon after Anterior Cervical Plating - An Unusual Complication: A Case Report

Sath S

Malays Orthop J, 2020 Nov;14(3):184-187.
PMID: 33403084 DOI: 10.5704/MOJ.2011.031

Complications in the form of esophageal injury, tracheal injury, injury to carotids, implant failure, loosening of screws, etc do occur after anterior cervical surgeries. Although intra-operative esophageal injuries are as such rare, there have been few reports of delayed esophageal perforation as well after anterior cervical surgeries. We report a very rare case of migration of missing screw from anterior cervical plate after anterior cervical corpectomy and plating, which had ultimately migrated down to colon and had to be removed via colonoscopy. Along with removal of migrated screw from colon, revision of failed anterior cervical surgery was done wherein plate and screws were removed with mesh cage left in-situ as it was snug-fit while pharyngeophageal perforation was explored and was found to be spontaneously healing, with addition of posterior Bohlman's interspinous wiring for added stability. Migration of screw from the anterior cervical plate into the colon although very rare, should be always kept in mind and its potentially serious complications. We also conclude that particular attention should be given to elderly people with poor bony quality who have high chances of implant failure, along with attention to proper cage size, screw position and proper locking of the screw to further lessen the chances of implant failure.

Revathi M, Sivagaami Sundari G, Ahmed Basha C, Alam M, Sagadevan S, Ahmad N

J Nanosci Nanotechnol, 2020 10 01;20(10):6547-6554.
PMID: 32385012 DOI: 10.1166/jnn.2020.18562

This investigation aims at the reclamation of Cr(VI) from synthetic electroplating industrial effluent by electroextraction process namely electrochemical ion exchange (EIX). An electrochemical ion exchange reactor of desired dimensions was fabricated with the help of ion-permeable membranes, stainless steel cathode and PbO₂ coated Ti expanded mesh anode. The performance of the reactor was studied in batch recirculation mode, continuous flow mode at different experimental conditions. The influence of various experimental factors, for instance, initial metal ion concentration (20, 300, 1000 mg/L of Cr(VI)), applied voltages (2.5 V, 5 V, 7.5 V, 10 V) and flow rates of the process stream (2, 4, 6, 8, 10, 12 and 14 ml/min) on removal/reclamation efficiency was deliberated. For comparison purposes, an electrodialysis process was conducted at the same optimal conditions. It was found that the EIX process with three compartments has more removal efficiency at optimum experimental conditions than the electrodialysis process. The continuous flow process of the reactor with 300 mg/L of Cr(VI) as inlet concentration has studied to predict the breakeven point of the reactor. It was noted that Cr(VI) ion concentration in the treated wastewater is almost zero up to the discharge of 20 liters of treated rinse water.

Razman J, Shaharin S, Lukman MR, Sukumar N, Jasmi AY

Med J Malaysia, 2006 Jun;61(2):142-6.
PMID: 16898302 MyJurnal

Laparoscopic repair of ventral and incisional hernia has become increasingly popular as compared to open repair. The procedure has the advantages of minimal access surgery, reduction of post operative pain and the recurrence rate. A prospective study of laparoscopic incisional hernia repair was performed in our center from August 2002 to April 2004. Eighteen cases (n: 18) were performed during the study period. Fifteen cases (n: 15) had open hernia repair previously. Sixteen patients (n: 16) had successful repair of the hernia with the laparoscopic approach and two cases were converted to open repair. The mean hernia defect size was 156cm2. There was no intraoperative or immediate postoperative complication. The mean operating time was 100 +/- 34 minutes (75 - 180 minutes). The postoperative pain was graded as mild to moderate according to visual analogue score. The mean day of discharge after surgery was two days (1 - 3 days). During follow up, three patients (16.7%) developed seroma at the hernia sac which was resolved with conservative management after three weeks. One (5.6%) patient developed recurrence six months after surgery. In conclusion, laparoscopic repair of incisional hernia particularly recurrent hernia has been shown to be safe and effective in our centre. However, careful patient selection and acquiring the necessary advanced laparoscopic surgical skills coupled with the proper use of equipment are mandatory before embarking on this procedure.

Fulltext Thoracoplasty with acrylic plate-marlex mesh combination following near total resection of sternum: a case of chondrosarcoma of sternum

Premnath N, Lo HL, Cheong YT, Manjit S

Med J Malaysia, 2002 Sep;57(3):368-70.
PMID: 12440279

Removal of the whole sternum for malignant tumours results in a large defect, causing severe deformity and possible paradoxical movements of the chest wall. The reconstruction of the resultant large defect of the chest wall is often complex and difficult. Commonly used materials include rib autograft, steel strus acrylic plate and various synthetic meshes such as Goretex or Marlex mesh, with a myocutaneous flap for coverage. A case of a 48-year-old man with sternal chondrosarcoma successfully treated with thoracoplasty using acrylic plate-marlex mesh combination following near total resection of sternum is reported.

Fulltext Curettage and Cementation in Giant Cell Tumour of the Distal Tibia Using Polypropylene Mesh for Containment: A Case Report

Pan, K.L., Chan, W.H.

Malays Orthop J, 2010;4(2):51-53.
MyJurnal

Giant cell tumours of bone are best treated by extended curettage and filling in of the defect with cement or bone graft. In more advanced stages, when there is extensive loss of cortical bone cover, containment of the filling material is not possible and resection and reconstruction is required. We report a case of a recurrent giant cell tumour of the distal tibia in a 21-year-old female with extensive cortical bone loss in which polypropylene surgical mesh was used to contain the bone cement, thus avoiding a resection.

Structural Behavior of Fibrous-Ferrocement Panel Subjected to Flexural and Impact Loads

Murali G, Amran M, Fediuk R, Vatin N, Raman SN, Maithreyi G, et al.

Materials (Basel), 2020 Dec 11;13(24).
PMID: 33322254 DOI: 10.3390/ma13245648

Ferrocement panels, while offering various benefits, do not cover instances of low and moderated velocity impact. To address this problem and to enhance the impact strength against low-velocity impact, a fibrous ferrocement panel is proposed and investigated. This study aims to assess the flexural and low-velocity impact response of simply supported ferrocement panels reinforced with expanded wire mesh (EWM) and steel fibers. The experimental program covered 12 different ferrocement panel prototypes and was tested against a three-point flexural load and falling mass impact test. The ferrocement panel system comprises mortar reinforced with 1% and 2% dosage of steel fibers and an EWM arranged in 1, 2, and 3 layers. For mortar preparation, a water-cement (w/c) ratio of 0.4 was maintained and all panels were cured in water for 28 days. The primary endpoints of the investigation are first crack and ultimate load capacity, deflection corresponding to first crack and ultimate load, ductility index, flexural strength, crack width at ultimate load, a number of impacts needed to induce crack commencement and failure, ductility ratio, and failure mode. The finding revealed that the three-layers of EWM inclusion and steel fibers resulted in an additional impact resistance improvement at cracking and failure stages of ferrocement panels. With superior ultimate load capacity, flexural strength, crack resistance, impact resistance, and ductile response, as witnessed in the experiment program, ferrocement panel can be a positive choice for many construction applications subjected to repeated low-velocity impacts.

Journal of Clinical and Health Sciences, 2021;6(1):46-49.
MyJurnal

Obturator hernia is rare, but it must be considered in elderly patients who present with small
bowel obstruction. The diagnosis is challenging unless there is a high index of suspicion as
the presenting symptoms and signs are usually non-specific. Presence of positive HowshipRomberg sign is considered pathognomonic. Early diagnosis and rapid surgical intervention
will reduce the high morbidity and mortality associated with undiagnosed obturator hernia. We
report a case of a 93-year-old female patient who was admitted to our surgical department with
symptoms of intestinal obstruction of 3-days duration. Howship-Romberg sign was negative.
Computed tomography (CT) demonstrated the presence of left obturator hernia with proximal
small bowel obstruction and no sign of strangulation. The patient had emergency laparotomy
post-CT where the incarcerated bowel loop was released and the obstructed bowel was
decompressed without any complication. The hernial defect was close with a mesh and the
patient had an uneventful recovery post-surgery. In this case, we highlight that diagnosis of
obturator hernia must always be considered in elderly patients who present with intestinal
obstruction. Urgent CT could establish a rapid pre-operative diagnosis and aids in appropriate
surgical intervention planning which is crucial in optimising the outcome.

Assessment of collagen-coated anterior mesh through morphology and clinical outcomes in pelvic reconstructive surgery for pelvic organ prolapse

Lo TS, Tan YL, Khanuengkitkong S, Dass AK, Cortes EF, Wu PY

J Minim Invasive Gynecol, 2014 Sep-Oct;21(5):753-61.
PMID: 24607796 DOI: 10.1016/j.jmig.2014.02.013

STUDY OBJECTIVE: To assess the morphologic features of anterior armed transobturator collagen-coated polypropylene mesh and its clinical outcomes in pelvic reconstructive surgery to treat pelvic organ prolapse.
DESIGN: Evidence obtained from several timed series with intervention (Canadian Task Force classification II-3).
SETTING: Chang Gung Memorial Hospital, Taoyuan, Taiwan, China.
PATIENTS: Between April 2010 and October 2012, 70 patients underwent surgery to treat symptomatic pelvic organ prolapse, stage III/IV according to the POP-Q (Pelvic Organ Quantification System).
INTERVENTION: Anterior armed transobturator collagen-coated mesh.
MEASUREMENT AND MAIN RESULTS: Morphologic findings and clinical outcome were measured. Morphologic features were assessed via 2-dimensional introital ultrasonography and Doppler studies. Clinical outcome was measured via subjective and objective outcome. Objective outcome was assessed via the 9-point site-specific staging method of the International Continence Society Pelvic Organ Prolapse Quantification before the operation and at 1-year postoperative follow-up. Subjective outcome was based on 4 validated questionnaires: the 6-item UDI-6 (Urogenital Distress Inventory), the 7-item IIQ-7 (Incontinence Impact Questionnaire), the 6-item POPDI-6 (Pelvic Organ Prolapse Distress Inventory 6), and the 12-item PISQ-12 (Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire), at baseline and at 12 months after the operation. Data were obtained for 65 patients who underwent the combined surgery and were able to comply with follow-up for >1 year. Ultrasound studies reveal that mesh length tends to shorten and decrease in thickness over the 1-year follow-up. Vagina thickness also was reduced. Neovascularization through the mesh was observed in <8.5% of patients in the first month and at 1 year, and was evident in approximately 83%. The mesh exposure rate was 6.4%. The recorded objective cure was 90.8% (59 of 65 patients), and subjective cure was 89.2% (58 of 65 patients) at mean (SD) follow-up of 19.40 (10.98) months. At 2 years, UDI-6, IIQ-7, and POPDI-6 scores were all significantly decreased (p < .001), whereas the PISQ-12 score was significantly increased (p = .01).
CONCLUSIONS: Ultrasound features suggest that the degeneration of collagen barrier may be longer than expected and that integration of collagen-coated mesh could occur up to 1 year. A substantially good clinical outcome was noted.

Assessment of collagen versus non collagen coated anterior vaginal mesh in pelvic reconstructive surgery: prospective study

Lo TS, Cortes EFM, Wu PY, Tan YL, Al-Kharabsheh A, Pue LB

Eur J Obstet Gynecol Reprod Biol, 2016 Mar;198:138-144.
PMID: 26849040 DOI: 10.1016/j.ejogrb.2016.01.004

OBJECTIVE: To evaluate the sonologic and clinical outcome of collagen coated (CC) versus non-collagen coated (NC) anterior vaginal mesh (AVM) for pelvic organ prolapse (POP) surgery.
STUDY DESIGN: The study is a prospective observational study which included 122 patients who had symptomatic POP stage III and IV. AvaultaPlus™ (collagen coated, CC group) was compared to Perigee™ (non collagen coated, NC group). Introital ultrasound morphology, measure of neovascularization by color Doppler and clinical outcomes were assessed. Student t test was used for comparison of pre- and post-operation continuous data (p value of <0.05).
RESULTS: A total of 110 (CC group=50, NC group=60) women completed the study. A woman in the CC group developed ureteral injury. Both groups had comparable morphologic and clinical outcomes however, the onset of changes in mesh thickness and neovascularization occurred earlier in the NC group (1 month) compared to the CC group (6 months to 1 year).
CONCLUSION: CC group was comparable to the NC group in terms of erosion rate, ultrasound and clinical assessment. Collagen coating may induce delayed inflammatory response however may also delay tissue integration. The onset of changes in mesh thickness and neovascularization may give us an insight toward utilization of collagen coated mesh for host-tissue integration.
