Effects of Caffeine Consumption on Autologous Full-Thickness Skin Graft Healing in an Animal Model.

Background There exists contradictory evidence that states both the beneficial and deleterious effects of caffeine on wound healing. The general population might unknowingly consume caffeine that negatively affects wound healing. The main objective of this study is to investigate the effect of daily caffeine consumption on wound healing, specifically full-thickness skin graft (FTSG). Methods Forty Sprague-Dawley rats were randomized into four groups of equal size: control-dose (CD), low-dose (LD), medium-dose (MD), and high-dose (HD) caffeine groups. After autologous FTSG, all subjects in the intervention group were given daily pure caffeine gavage. The FTSG was explanted 7 days posttransplant. The graft viability, secondary contraction, and adherence were evaluated macroscopically, while fibroblast and collagen deposition was analyzed microscopically with hematoxylin eosin stain. Results The least graft viability (72.8 ± 20.7%, clinical wound assessment scale [CWAS] 2.4), highest secondary contraction (11.4 ± 10.5%), and fibroblast count (331.8 ± 88.6 cells/5 high power fields) were observed in the MD group. More collagen synthesis was observed in subjects who consumed caffeine. The level of secondary contraction, fibroblast count as well as graft viability and collagen synthesis were positively correlated. Conclusions Daily consumption of caffeine impairs graft viability when given in medium dose and increases collagen synthesis, irrespective of dosage. This study was in experimental rats; the results are not directly translatable to humans.

Radiotherapy service amidst COVID-19: Experience from Tertiary Referral Hospital in Semarang, Indonesia.

Background: Several changes in hospital policies took place to mitigate the spread of Coronavirus disease 2019 (COVID-19). However, the patient's perception to these abrupt changes in medical services is not known. This study analyzed the quality of radiotherapy service during the COVID-19 pandemic and the patient's perception of them. Methods: This descriptive study will qualitatively assess cancer patient perception of the quality of radiotherapy service during COVID-19 pandemic. Willing participants were given a questionnaire that explore two major aspects: the patient's general knowledge of COVID-19 and their perception of radiotherapy service during the pandemic. Results: The 145 participants of this study were generally well-informed about the significance of COVID-19 pandemic. Most respondents claimed to adequately practice preventive measures and put high regards in personal protective equipment (PPE) worn by them and healthcare workers for their safety. Their level of trust to all healthcare workers remained high and identified hospital announcements (television, brochures) educated them the most in regards to the relationship of COVID-19 and cancer. Conclusion: The changes in hospital policies and radiation oncology service in our institution were well-received by the study population. Despite the majority of respondents were afraid and anxious of being infected of COVID-19 while undergoing treatment, only a minority of them contemplated to delay or completely stop going for treatment. By adhering to major guidelines and adjustments of local resources, the delivery of radiotherapy service can remain consistent during the pandemic.

Giant conjunctival melanoma in a paranoid schizophrenic man: A case report.

INTRODUCTION: and importance: Conjunctival melanoma (CM) is a rare and potentially lethal ocular tumor. As with any oncologic disease, early diagnosis and appropriate treatment of CM is paramount to limit morbidity and increase life expectancy. However, patients with severe mental disability with social isolation are usually presented in late-stage disease. CASE PRESENTATION: This report presents a case of a 55-year-old man with paranoid schizophrenic man with an extraordinarily large CM due to neglect. The patient suffered from complete left eye blindness with no clinical and radiological evidence of metastasis. CLINICAL DICUSSION: Clinicians must bear in mind the limited patient compliance and family support of mentally-ill patients that restricts treatment modalities that would have otherwise been applicable for cooperative patients. The importance multidisciplinary approach, choosing the simpler but effective surgical technique should be prioritized. INTERVENTION AND OUTCOME: Left exenteration and tumor wide excision was performed. The left orbital defect was reconstructed using forehead flap and split-thickness skin graft (STSG). The uncooperative nature of the patient posed early post-operative challenges that necessitates subsequent operation to drain seroma. The patient was discharged 16-days after operation with acceptable cosmetic and clinical results. However, the patient failed to return to the clinic for longer post-operative evaluation. CONCLUSION: A multidisciplinary approach is mandatory to treat complex cases such as this report. Surgeons are advised to adopt simpler surgical approach that will require minimal self-care and should encourage family members to continuously support the patient.

Pneumorrhachis and hyponatremia after a neck hack-A case report.

INTRODUCTION: Penetrating cervical spinal cord injury (SCI) is a rare clinical entity that requires a multitude of health care specialists for proper management. The unpredictable nature of penetrating SCI and complex systemic sequela contribute to the high mortality rates of penetrating SCI. PRESENTATION OF CASE: An 18-year-old-male patient was admitted to the emergency department with tetraparesis following a penetrating injury to the neck. Radiological examination revealed fractures of C4 and C5 spinous processes and extensive intradural pneumorrhachis. The patient was managed operatively with laminectomy, vertebral augmentation, and duroplasty. An acute decreased level of consciousness was observed four days after the operation. Laboratory investigation revealed critically low plasma sodium level. The patient remained decerebrated despite electrolyte correction and pronounced brain dead on the seventh postoperative day. DISCUSSION: Metabolic derangements and pulmonary physiologic changes following trauma are lethal complications. Hyponatremic encephalopathy and disrupted pulmonary function caused by high cervical compression by the extensive pneumorrhachis contributes to the morality in this case report. CONCLUSION: This case report presents a rare clinical entity along with its' complications. Prompt clinical stabilization, strict biochemical monitoring, and multidisciplinary care from health care specialists are mandatory for SCI patients.

Kidney transplantation in Indonesia: An update.

OBJECTIVE: Indonesia has overcome several barriers to the growth of kidney transplantation within the past decade. Currently, the procedure is increasingly performed in several centers across the country. However there are limited publications on kidney transplantation from Indonesia, especially from centers outside Jakarta. This study aims to give a brief overview on transplantation performed, discuss current efforts and progresses of transplantation in Indonesia and chiefly Semarang. METHODS: Retrospective analysis of 20 transplant cases in Semarang during 2014-2018 was performed. Information from other transplant centers was acquired through formal correspondences with 11 central teaching hospitals in Jakarta, Surabaya, Yogyakarta, Malang, Bali, Solo, Palembang, Aceh, Medan, Bandung, and Padang. RESULTS: There were 629 recorded kidney transplantations performed in 12 centers, and we report on 245 cases with viable data. The average age of kidney recipients were younger (35.4 years old) compared to the donors (41.3 years old). Approximately half of the kidneys were obtained from related donors (49.0%) and there was only one case of cadaveric donor. The three leading etiologies of end-stage renal disease were hypertension (37.4%), diabetes mellitus (26.1%), and autoimmune disease (11.3%). There is only one center that has performed more than 100 kidney transplants in Indonesia. CONCLUSION: Indonesia has successfully overcome several major hurdles that had previously hindered the growth of transplantation. Further improvement should concentrate on the development of integrated organ transplant infrastructure, decentralization of transplant professionals, establishment of National kidney transplant database and changing the Nation's paradigm on cadaveric organ donor through public education.

The outcome of laparoscopic subtotal cholecystectomy in difficult cases - A case series.

INTRODUCTION: Laparoscopic subtotal cholecystectomy (LSC) is a widely used technique for managing cholelithiasis with severe cholecystitis. The increasing popularity its utilization is due to the good safety profile and acceptable results. This case series evaluates the short- and long-term results of Indonesian patients who underwent LSC with an objective to determine whether the procedure can be a standard approach for difficult cholecystectomy in our institution. PRESENTATION OF CASE: Thirty-four Indonesian patients (26 men, 8 women) with the mean age of 54.6 years (median 54 years, range 30-84 years) who underwent LSC were retrospectively analyzed. Nineteen patients are suffering from type II diabetes mellitus and fourteen patients with suspected choledocoholithiasis underwent ERCP prior to LSC. The major postoperative diagnosis was acute cholecystitis (16 patients), followed by gallbladder empyema (10 patients), chronic cholecystitis (5 patients), history of cholangitis (1 patient), Mirizzi's syndrome (1 patient) and stone retention post-ERCP (1 patient). DISCUSSION: The mean operating time was 158minutes (median 150minutes, range 60-240minutes), mean length of hospital stay of 4.6days (median 3days, range 2-33days) and drain usage for 3.6days (median 3.0days, range 1-19days). Postoperatively there was one case of bilioenteric fistula, one case of stone retention and two cases of prolonged upper gastrointestinal symptoms. There is no case of biliary leakage, peritonitis or wound infection. CONCLUSION: The outcome of LSC in this case series is comparable with other publications showing a general favorability of LSC. Further studies are needed to elucidate the clinical benefits of several LSC technical points such as stump closure, posterior wall diathermy and drain usage. Based on this preliminary finding, LSC can be applied as a standard procedure for difficult cases in our institution.

A preclinical evaluation of alternative synthetic biomaterials for fascial defect repair using a rat abdominal hernia model.

INTRODUCTION: Fascial defects are a common problem in the abdominal wall and in the vagina leading to hernia or pelvic organ prolapse that requires mesh enhancement to reduce operation failure. However, the long-term outcome of synthetic mesh surgery may be unsatisfactory due to post-surgical complications. We hypothesized that mesh fabricated from alternative synthetic polymers may evoke a different tissue response, and provide more appropriate mechanical properties for hernia repair. Our aim was to compare the in vivo biocompatibility of new synthetic meshes with a commercial mesh. METHODS: We have fabricated 3 new warp-knitted synthetic meshes from different polymers with different tensile properties polyetheretherketone (PEEK), polyamide (PA) and a composite, gelatin coated PA (PA+G). The rat abdominal hernia model was used to implant the meshes (25 × 35 mm, n = 24/ group). After 7, 30, 60, 90 days tissues were explanted for immunohistochemical assessment of foreign body reaction and tissue integration, using CD31, CD45, CD68, alpha-SMA antibodies. The images were analysed using an image analysis software program. Biomechanical properties were uniaxially evaluated using an Instron Tensile® Tester. RESULTS: This study showed that the new meshes induced complex differences in the type of foreign body reaction over the time course of implantation. The PA, and particularly the composite PA+G meshes, evoked a milder early inflammatory response, and macrophages were apparent throughout the time course. Our meshes led to better tissue integration and new collagen deposition, particularly with the PA+G meshes, as well as greater and sustained neovascularisation compared with the PP meshes. CONCLUSION: PA, PA+G and PEEK appear to be well tolerated and are biocompatible, evoking an overlapping and different host tissue response with time that might convey mechanical variations in the healing tissue. These new meshes comprising different polymers may provide an alternative option for future treatment of fascial defects.
