Salauddin SA, Ghazali H

Malays J Med Sci, 2019 Nov;26(6):137-142.
PMID: 31908595 MyJurnal DOI: 10.21315/mjms2019.26.6.14

Background: Penile augmentation using injection of a foreign body into penile skin was mainly performed by non-medical personnel. Majority of these patients end up with complication of an abnormal mass formation known as penile paraffinoma.
Methods: We described three different surgical techniques for correction of penile paraffinoma based on our single-centre experience. Informed consents were obtained from patients whose photographs were taken during the operation step.
Results: In general, three patients had simple excision biopsy with primary suturing, four patients underwent single stage excision of circumferential granuloma with bilateral scrotal skin flap reconstruction and one patient experienced dual stage procedure. Three of them were injected with paraffin, one with silicone and the remaining four were unable to identify the substance used. All patients successfully underwent the surgical procedure and four of them had minor post-operative surgical site infection and wound gapping.
Conclusion: All patients recovered well and the mean International Index of Erectile Function (IIEF-5) score obtained was 24.25. In our experience, excision biopsy was adequate for focal mass and reconstructive surgery using bilateral scrotal flap was suitable for circumferential mass.

Epididymo-orchitis is a medical condition characterised by inflammation of epididymis and testis which is a common urological diagnosis encountered by healthcare professionals. Misdiagnosis and under treatment can lead to poor outcome such as infarction and abscess formation.We presented a33-year-old man, with no known medical illness, presented with one-week history of left testicular pain, swelling and fever. He was commenced on Amoxicillin by his general practitioner. Physical examination showed left swollen and tender testis and normal right testis. Investigations showed an elevated white cell count (WCC) 41.3x103 /L and colour doppler ultrasound (USG) testes showed left epididymo-orhitis.He was admitted and treated with IV Unasyn®(Ampicillin+Sulbactam) for 5 days. His symptoms improved, and he discharged home well with one week oral Unasyn®. He represented 2 weeks later with worsening left scrotal swelling and pain. Clinical examination found a swollen, tender and erythematous scrotum with 1x1cm defect in the left scrotum with purulent discharge.He underwent operation incision and drainage of left scrotum and left orchidectomy. Post-operatively he recovered well. Histopathology reported as epididimo-orchitis with abscess, necrosis and perforation.As a conclusion, testicular rupture and abscess formation secondary to epididymo-orchitis is an uncommon reported complication. Immediate recognition and treatment is crucial as a delayed diagnosis can lead to sepsis and infertility.

Degloving injury is severe and commonly results from a huge rotational force which avulses the skin and subcutaneous tissue from its underlying fascia. This injury is associated with high morbidity and mortality if mismanaged. Perineal degloving injury commonly associated with urethral injury which can be further classified into anterior and posterior urethral injury. This study retrospectively evaluated management of traumatic perineal degloving injury compared to standard approach.A total of 3 cases of open perineal degloving injuries been identified and was managed at our centre at the year 2017. 2 cases of degloving wound of scrotum and one case of crush perineal injury with transected posterior urethral were included. We reviewed methods of management and clinical outcomes of these patients. All patients promptly underwent wound debridement and surgical repair after immediate diagnosis and resuscitation. Suprapubic insertion of catheter is crucial in managing the urethral injury. The case of crush perineal injury with transected urethral treated with operation primary urethral anastomosis, de-functioning of stoma and external fixation of pelvis. Unfortunately, this case was complicated with rupture at anastomotic urethral site after a traumatic CBD insertion during his hospitalization and he was treated conservatively with CBD. All patients did well clinically with their wounds healed well.We showed a multidisciplinary team approach consisting of colorectal surgeon, urologist, orthopaedics surgeon and plastic surgeon, together with prompt diagnosis provides the best outcome were for the treatment of open perineal degloving injury.

Adsorption technology has led to the development of promising techniques to purify biogas, i.e., biomethane or biohydrogen. Such techniques mainly depend on the adsorbent ability and operating parameters. This research focused on adsorption technology for upgrading biogas technique by developing a novel adsorbent. The commercial coconut shell activated carbon (CAC) and two types of gases (H2S/N2 and H2S/N2/CO2) were used. CAC was modified by copper sulfate (CuSO4), zinc acetate (ZnAc2), potassium hydroxide (KOH), potassium iodide (KI), and sodium carbonate (Na2CO3) on their surface to increase the selectivity of H2S removal. Commercial H2S adsorbents were soaked in 7 wt.% of impregnated solution for 30 min before drying at 120°C for 24 h. The synthesized adsorbent's physical and chemical properties, including surface morphology, porosity, and structures, were characterized by SEM-EDX, FTIR, XRD, TGA, and BET analyses. For real applications, the modified adsorbents were used in a real-time 0.85 L single-column adsorber unit. The operating parameters for the H2S adsorption in the adsorber unit varied in L/D ratio (0.5-2.5) and feed flow rate (1.5-5.5 L/min) where, also equivalent with a gas hourly space velocity, GHSV (212.4-780.0 hour-1) used. The performances of H2S adsorption were then compared with those of the best adsorbent that can be used for further investigation. Characterization results revealed that the impregnated solution homogeneously covered the adsorbent surface, morphology, and properties (i.e., crystallinity and surface area). BET analysis further shows that the modified adsorbents surface area decreased by up to 96%. Hence, ZnAc2-CAC clarify as the best adsorption capacity ranging within 1.3-1.7 mg H2S/g, whereby the studied extended to adsorption-desorption cycle.
Fulltext Enabling chlorophyll photo-response for in-line real-time noninvasive direct probing of the quality of palm-oil during mill process

During the milling process of palm oil, the degree of palm fruit ripeness is a critical factor that affects the quality and quantity of the oil. As the palm fruit matures, its chlorophyll level decreases, and since chlorophyll in oil has undesirable effects on hydrogenation, bleachability, and oxidative degradation, it's important to monitor the chlorophyll content in palm oil during the milling process. This study investigated the use of light-induced chlorophyll fluorescence (LICF) for non-invasive and real-time monitoring of chlorophyll content in diluted crude palm oil (DCO) located at the dilution and oil classification point in palm oil mill. An LICF probe was installed at the secondary pipe connected to main DCO pipeline, and the system communicates with a computer located in a separate control room via a Wi-Fi connection. Continuous measurements were recorded with an integration time of 500 ms, averaging of 10, and a time interval of 1 min between each recording during the oil mill's operation. All data were stored on the computer and in the cloud. We collected 60 DCO samples and sent them to the laboratory for American Oil Chemists' Society (AOCS) measurement to compare with the LICF signal. The LICF method achieved a correlation coefficient of 0.88 with the AOCS measurements, and it also provided a direct, quantitative, and unbiased assessment of the fruit ripeness in the mill. By incorporating Internet of Things (IoT) sensors and cloud storage, this LICF system enables remote and real-time access to data for chemometrics analysis.
