Published: April 2022

Entrepreneurship plays a pivotal role in economic growth for Indonesia. Unfortunately, the number of entrepreneurs in Indonesia is still lagging behind other ASEAN countries. The emergence of knowledge-based entrepreneurship makes universities become one of the vital supply sources for creating entrepreneurs. Even though it has institutional support from the Indonesian government, entrepreneurship is still not considered a promising alternative career choice. Therefore, this study aims to analyze the effect of university institutional support (perceived educational support, concept development support, and concept development support) and personal traits variables (self-efficacy and proactive personality) on Indonesian students' entrepreneurial intention. This study was conducted using a judgmental sampling technique on 302 active university students in Indonesia who have received entrepreneurship education. Data analysis in this study was carried out using the PLS-SEM. The findings of this study indicate that perceived educational support directly affects entrepreneurial intention. While, perceived concept development support and perceived business development support positively shape self-efficacy, leading to entrepreneurial intention. This study also confirms self-efficacy and proactive personality as predictors of entrepreneurial intention. Furthermore, the study also shows that self-efficacy mediates the relationship between proactive personality and Indonesian students' intentions to be entrepreneurs.

Published: April 2022

Sea urchins (Diadema setosum) are marine animals belonging to phylum Echinodermata which are often found in the Wakatobi's waters. Although Indonesia is one of the exporters of sea urchins, the use of sea urchins as medicinal and health food products has not been widely used. This is due to the limited information about the potential active compounds contained in sea urchins from Indonesian waters. This study aimed to determine the bioactivity and antioxidant activity of gonad extract of sea urchin (Diadema setosum). The sample test consisted of several stages, namely extraction by maceration using 96% ethanol solvent, phytochemical test and antioxidant activity testing. The results showed that the ethanol extract of the gonads of sea urchin (Diadema setosum) contained alkaloids, steroids, triterpenoids and tannins. The results of the antioxidant activity test of the ethanol extract of the gonads of sea urchin (Diadema setosum) showed that the extract had no potential as an antioxidant because it had IC50 value of > 250 ppm. The IC50 value was 4460.1505 ppm. The novelty of this study resulted in data of bioactive compounds and antioxidant activity of sea urchin gonads Diadema setosum that are useful for different herbal formulations as anti-tumour, anti-cancer, anti-inflammatory, analgesic, anti-fatigue, anti-Parkinson effect, and anti-hypoglycemic.

Published: April 2022

Binjai (Mangifera Caesia Jack. Ex. Wall) is one of the Mangifera species with a better antioxidant source and significantly high phenolic-flavonoid contents. Exploring the bioactive potential of Binjai must be necessary for the treatment and prevention of UV-mediated diseases to be developed due to sunscreen emulgel. This study aims to identify quercetin and mangiferin, and determine the sun protection factor (SPF) of Binjai leaves and the effect of the different gelling agents on the sunscreen emulgel SPF. Binjai leaves were extracted with methanol using the Soxhlet apparatus. Gas Chromatography-Mass Spectrometry (GC-MS) was used for the remaining methanol solvent. The quercetin and mangiferin identification was examined by DPPH (2.2-diphenyl-1-picrylhydrazyl) spray-on TLC. The emulgel was made using three optimum formulas with different gelling agents (Carbopol, Na-CMC, and tragacanth). The SPF was determined by measuring the absorbance using UV-Vis Spectrophotometer. The extract was identified as not containing methanol solvent residual. Identification with TLC showed one yellow spot from the extract that was parallel with quercetin and also mangiferin on a purple background after spraying the DPPH. The extract with a concentration of 2500 ppm obtained an SPF of 23.01 compared to quercetin (50 ppm) which has an SPF of 16.93. The emulgel of the extract with the highest SPF of 21.38 was obtained from the Carbopol formula. The methanol extract of Binjai leaves has ultra-protection as a sunscreen with the variation of different gelling agents on the emulgel preparation did not affect the in vitro sunscreen activity.

Published: April 2022

Ultrasonic-Assisted Extraction (UAE) technology is an effective method for the extraction of chemical constituents from plant materials. The antioxidant activity found in Musa balbisiana Colla may be related to antigout activity, where there is a role for antioxidants in the inhibition of xanthine oxidase activity. The extraction of secondary metabolites from Musa balbisiana Colla using the UAE method has never been reported; in addition, antioxidant testing using the FRAP method and uric acid test have never been carried out. This research aims to gain ultrasonic extract from the unripe Musa balbisiana Colla pulp using the UAE method and obtain information about secondary metabolites and their bioactivity as antioxidant and antigout agents. Ethanolic extract was obtained by the UAE method, total phenolic content was determined by the Folin–Ciocalteu method, antioxidant activity was measured using DPPH and FRAP method, then the uric acid level was measured using uric acid test kit. The results showed that the antioxidant activity test using the DPPH and FRAP methods gave IC50 values of 411.59 ± 0.1336 mg/L and 98.03 ± 0.2926 mg/L, respectively. The total phenolic content value of 823.95 ± 3.9806 mg GAE/g ultrasonic extract is thought to have a role in high antioxidant activity. Furthermore, ultrasonic extract with a concentration of 50 mg/L has activity in reducing uric acid levels by around 10%. It can be concluded that the ultrasonic extract produced by the UAE has potential as a source of antioxidant and antigout agents.

Authors: Nugroho Juni Jekti , Elfira Fanny Ayu
Published: April 2022

Background: Endodontic is a treatment that aims to eliminate bacteria from the root canal system. One of the bacteria that causes root canal treatment failure is Enterococcus faecalis. Chemomechanical preparation and root canal irrigation are not sufficient to eliminate bacteria completely, so root canal medication is necessary to make it more efficient. Moringa leaves contain tannins, flavonoids and saponins which have antibacterial properties. Objective: To determine whether moringa leaf nanoparticle paste had antibacterial effectiveness against the bacterium E.faecalis. Method: Experimental laboratory with posttest with control group design with Kirby-Bauer method. The sample consisted of moringa leaf nanoparticles with concentrations of 1% and 2.5%, calcium hydroxide and aquadest with each of them being repeated 3 times. The diameter of the inhibition zone was de-termined based on the inhibitory ability of the bacteria saturated on MHA agar media. Results: the result showed that the ave-rage diameter of the inhibition zone of moringa leaf nanoparticle paste with concentrations of 1% was 8.48 mm, 2.5% was 9.17 mm and calcium hydroxide was 10.2 mm. Data processing showed that the 2.5% moringa leaf nanoparticle paste group had the same antibacterial effect as the calcium hydroxide group. Conclusion: Moringa leaf nanoparticle paste (Moringa oleifera) with concentrations of 1% and 2.5% was quite effective in inhibiting the growth of E.faecalis.

Authors: Bintang Andi Kurnia , Musyawwirina Marina , Basri Muhammad Iqbal
Published: April 2022

Introduction: Benign paroxysmal positional vertigo (BPPV) is commonly found in older women; caused by the presence of otoconia in semicircular canals, which will stimulate the ampulla. Degeneration of otoconia and abnormal calcium metabolism could contribute to BPPV. This study aims to find a difference in serum calcium levels between idiopathic BPPV and non-BPPV vertigo patients. Methods: Cross-sectional study was held in Wahidin Sudirohusodo hospital in Makassar from August to October 2019. Subjects who fulfilled the criteria were divided into two groups (BPPV and non-BPPV). Venous blood was taken to obtain serum calcium levels. Statistical analysis was performed with SPSS software version 21. Chi-square and Mann-Whitney tests were used to determine the relationship between variables. Result: As many as 45 subjects were grouped into BPPV (n=30) and non-BPPV (n=15). Majority of subjects were female (n=30). Mean serum calcium level was significantly lower in BPPV group (8.51±0.67 vs 8.9±0.63; p=0.023). Area under curve of serum calcium level according to vertigo type was 22.4% (p<0.05). Optimal cut-off point for serum calcium level was 8.55 (p=0.024). Discussion: Majority of subjects in this study were females between 40-60 years old. Patients with BPPV tend to have lower serum calcium levels. Possible underlying me-chanisms include estrogen deficiency, otoconial degeneration, vitamin D deficiency, lack of sunlight, and abnormal calcium me-tabolism. Examination of serum calcium level and calcium supplementation could be considered for these patients. Some factors that affect serum calcium level were not considered in this study. It was concluded that examination of serum calcium level and calcium supplementation could be considered for patients with BPPV.
Lifestyle potential against recurrent intraoral herpes recurrence rate: a case series
Authors: Megawati Ani , Hidayat Wahyu
Published: April 2022

Introduction: Herpes Simplex Virus type 1 (HSV-1) is the virus that most often infects the oral cavity. HSV-1 in the latent phase migrates to the trigeminal ganglion after primary infection and can reactivate to cause recurrent intraoral herpes (RIH). The recurrence of RIH is multifactorial and triggered by decreased immunity, fatigue, hypersensitivity, stress, and ultraviolet. Case: Three male patients came to the Oral Disease Clinic with ulcers in the oral cavity. The patients experienced prodromal symptoms and the characteristic features of RIH were multiple rounded ulcers spreading and surrounded by erythematous areas. Anti-HSV-1 IgG examination showed reactive results. Management: The therapy was acyclovir and trigger factor modifica-tion. The oral lesions of all patients recovered after therapy and there were no new lesions. Conclusion: Lifestyle and habits have a high potential to be a triggering factor for RIH recurrence, so comprehensive treatment is needed to prevent recurrence.

Authors: Alexeyev D. O. , Katugin O. N. , Bizikov V. A.
Published: April 2022

Two subspecies of the schoolmaster gonate squid Berryteuthis magister (Berry, 1913) have been described to date: B. magister nipponensis Okutani et Kubodera, 1987 from the Pacific Ocean off the coast of Japan and Sea of Japan, and B. magister shevtsovi Katugin, 2000 from the Sea of Japan. The gonatid species Gonatus septemdentatus Sasaki, 1915, which was later recognized as a junior synonym ofB. magister, was also described from the Sea of Japan. Comparisons among these three taxa and with the nominative subspecies using morphological and ecological features suggest that individuals of the genus Berryteuthis inhabiting the Sea of Japan belong to the species B. septemdentatus (Sasaki, 1915), which should be considered the valid name for this taxon.

Authors: Shakil Mohammad Imdadul Hoque , Islam Nahida
Published: April 2022

Background: The motive of this observe is to compare the consequences of acute number one repair of extraarticular ligaments with staged surgical treatment for acute knee dislocations (KDs) and multiligament knee injuries (MLKIs). Materials and methods: The atudy has conducted in Department of Orthopedic, UHC sadar, Mymensingh. During the period of January 2013 and May 2021, 67 consecutive patients identified with MLKI or KD have been noted or visited our institution. Of these, 37 sufferers who underwent acute restore of extraarticular ligaments inside three weeks of damage had been included on this observe. These patients were retrospectively categorised into two corporations: people who underwent best primary repair (repair group) and people who underwent staged reconstructive surgical operation (staged group). Follow-up exam protected range of motion (ROM), knee joint balance (Lachman test, posterior drawer take a look at, and varus and valgus stress test), Lysholm knee score, Tegner interest scale, and Knee damage and Osteoarthritis and effect Score (KOOS). Results: Twelve of the 37 sufferers did not want or preference similarly surgical treatment and were protected inside the restore institution. No great distinction becomes determined in demographic facts among the restore and staged businesses. Although staged surgery decreased high-quality posterior drawer check results, no giant difference became located between the 2 businesses concerning ROM, different knee joint balance tests, Lysholm rankings, Tegner scale, or KOOS. Conclusions: all patients lower back to their activities of each day residing and preinjury career ranges. Acute primary restore of extraarticular ligaments gives critical knee stability without varus/valgus instability and may lessen the need for next cruciate ligament reconstruction.

Published: April 2022

This study aims to investigate the epidemiological profile of patients and the diagnostic and therapeutic contribution of emergency laparoscopy at the Centre Hospitalier Auxerre (CHA) in France. It’s a year-long descriptive retrospective study conducted at the Auxerre Hospital. Out of 1130 laparoscopies, 245 were emergencies, i.e., 21.68% of laparoscopies. The mean age of our study population was 37 ± 22.78 years with patients ranging from 3 to 93-year-old. The sex ratio was 0.96. The main indications for emergency laparoscopies at CHA were acute appendicitis (44.9%) followed by exploratory laparoscopies (18.8%). Eight percent (8%) of the emergency laparoscopies were later converted to laparotomies, for the following reasons: difficult exposure, multiple adhesions, intestinal dilatation, hypercapnia. Regarding the surgical procedures, an appendectomy was performed in 37.1% of cases whereas peritoneal lavage and drainage following appendectomy were performed cavity in 18.4% of cases. We highlight a laparoscopic transdiaphragmatic pericardial fenestration performed to drain pericardial effusion due to cardiac tamponade, an uncommon procedure even in western practice. The mean duration of the procedure was 53 ± 32.52 minutes, ranging from 11 minutes and 214 minutes. The low postoperative morbidity of 6.53% in our study is one of the undeniable advantages of the laparoscopic approach. The other advantage of laparoscopy is the shortened hospital stay, even in the context of an abdominal emergency. Ample evidence of this is the average hospital stay of 5±5.4 days with 60.4% of patients spending less than 5 days in the hospital.

Background: Carcinoma of the breast is the most common female cancer and its incidence is rapidly increasing over the last few decades. In Bangladesh, breast cancer is an issue of gaining concern. Receptor status and histological grade are two important prognostic factors of carcinoma breast. Aim of the study: To assess the relation and distribution of receptor status and tumor grade among pre and postmenopausal patients of carcinoma breast. Methods: This cross-sectional observational study was carried out in the Department of General Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU) Dhaka over a period of one year, a total of 59 admitted female patients with histologically proven carcinoma of the breast were divided into two groups included in this study. The premenopausal age group was considered as a group I (n=31) and the postmenopausal age group was considered as group II (n=28). Data regarding the tumor histopathological type, grading, and receptor status along with other variables were included in a pre-designed data collection sheet. After compiling data, Statistical analyses of the data were done with Statistical Packages for Social Sciences (SPSS- 22). Results: Sociodemographic variables and personal histories leading to a risk of breast cancer have no significant difference between pre and postmenopausal groups. Invasive ductal carcinoma (grade-II) was predominant in both groups. Estrogen and progesterone receptor-negative tumors were more frequent in premenopausal patients and estrogen and progesterone receptor-positive tumors were more frequent in a postmenopausal patient, but no statistically significant difference between the two groups. More than eighty percent of tumors were human epidermal growth factor-2 negative in both groups. The frequency of estrogen and progesterone receptor positivity gradually reduce from grade I to III in both groups and the frequency of estrogen and progesterone receptor negativity gradually increase from grade

Background: Surgical site infections (SSIs) are still a major problem in surgical practice. Despite the preventive strategies such as antibiotic prophylaxis and anti-septic skin cleansing, the SSI rate remains above 15 % after general abdominal surgery. This complication is also common after open choledocholithotomy. Several studies have shown that wound drainage is beneficial for reducing infection; however, there is a paucity of data regarding its benefit in open choledocholithotomy. Objective: To assess the effectiveness of placing a drain in the subcutaneous plane in order to reduce superficial SSI after open choledocholithotomy. Methods: Following convenience sampling, a total of 44 patients who underwent open choledocholithotomy from March 2019 to July 2021 were included in the study. Patients were divided into two groups. A subcutaneous closed suction drain was inserted in 19 patients (group I) and no subcutaneous drain was placed in 25 patients (group II). Daily drain collection was recorded in the case group. All the patients were examined and evaluated postoperatively for detection of wound seromas, superficial SSIs, and wound dehiscence. Data analysis and presentation made by statistical software SPSS 22 windows version 10. Results: It was observed that 10.5% of patients had SSI in group I and 60.0% in group II. The difference was statistically significant (p=0.001) between the two groups. The mean postoperative hospital stay was 11.58±2.91 days in group I and 15.04±5.78 days in group II. The difference in length of postoperative hospital stay was statistically significant between the two groups. Organisms isolated from bile culture and wound swab culture both are dominated by Escherichia coli. Conclusion: The placement of a drain in the wound in open choledocholithotomy showed a positive impact on the prevention of superficial surgical site infection. It also significantly reduces the length of hospital stay and SSSI rate.

Chromophobic renal cell carcinoma with sarcomatoid differentiation is a rare tumor characterized by a biphasic tumor with both classic epithelial components and sarcomatoid components with poor prognostic factors, usually in association with the rhabdoid contingent which has the potential to behave aggressively and metastasize. We report a particular case of recurrence of this entity in a male patient in which the diagnosis was suspicious preoperatively for the tumor evolution time and the size of the mass and the imaging data performed. The patient underwent extensive left total nephrectomy and lymph node dissection. The postoperative follow up was marked by early appearance of recurrence within 6 weeks after surgery.

Background: Undescended testis is a common genitourinary anomaly in a male child. Orchiopexy is the mainstay of treatment for undescended testis (UDT). Method of fixation may be sub dartos or extra dartos approach technique. This study is designed to find out the outcome of the extra dartos pouch fixation technique of orchiopexy in undescended testis. Objective: To evaluate the outcome of the extra dartos pouch fixation technique of orchiopexy in retaining testis in the scrotum. Methodology: This prospective observational study was conducted from January 2019 to April 2020 in the Department of Pediatric Surgery, Mymensingh Medical College, Mymensingh. A total of 30 patients with UDT who fulfilled the inclusion and exclusion criteria were included in this study group. History was recorded in a data collection sheet after taking informed written consent from the parents/guardians. Proper clinical examination, investigations were done. Pre and postoperative clinical and sonographic findings were taken to evaluate the outcome of the extra dartos pouch fixation technique of orchiopexy in undescended testis. All data were analyzed by SPSS version 20.0 software. Result: A total of 30 patients with undescended testis were included in this study. Age range 6 months to 6 years with a mean age of 3.48±1.77 years. Among 30 patients 19(63.3%) had right-sided and 11(36.7%) had left-sided UDT. Sonological localization in the inguinal canal was 21(70%), the superficial inguinal ring was 9(30%). The associated hernia was present in 27(90%) patients. Preoperative sonographic measurements of mean length and breadth of testis were 1.49±0.45cm and 0.88±0.34 cm respectively. Postoperative sonographic measurements of mean length and breadth were 1.46±0.47cm and 0.87±0.35cm respectively. The comparison between pre and postoperative sonographic measurement of length and breadth of testis was 0.098 ± 0.027cm and 0.03 ± 0.01cm respectively. No ascent of the testis nor testicular atrophy .....

The increasing demand for aesthetics has resulted in the development of several techniques in dentistry, mainly to restore anterior teeth. Meanwhile, conservative treatments should always be the first therapeutic option for any type of restoration. Thus, the solution of aesthetic problems involving morphological changes or diastemas should respect the minimally invasive dentistry’s standards. In this context, ceramic veneers represent the best choice providing great reproduction of natural appearance, a color stability and periodontal biocompatibility. However, they have to be properly indicated by the dentist. Besides, the clinical procedure is still considered as complicated and requiring a high level of proficiency. This paper reports a clinical case where anterior diastemas were aesthetically corrected using ceramic veneers.

Primary bladder adecarcinoma (PBA) is a rare entity representing 0.5 to 2% of all bladder malignancies. The clinical symptomatology: is not specific, the treatment is essentially surgical, chemotherapy and radiotherapy are discussed. For some authors, concomitant chemoradiotherapy seems to be promising for infiltrating tumors of the bladder. The evolution is often rapidly progressive and fatal. We report a case of primary adenocarcinoma of the bladder who consulted the department of Oncology-Radiotherapy UHC Mohammed VI Marrakech because of the rarity of these tumors and a review of the literature.

Fibrous dysplasia is rare benign sporadic non inherited disease that can affect any bone, but a predilection for ribs, craniofacial and lower limb bones is described in the literature. Only few cases concerning the humerus have been reported. Radiographically, typical lesions appear as an area of radiolucent ground glass matrix. Here, we present a case report of a fibrous dysplasia located in the humerus revealed by chronic elbow pain in a 63 years-old woman. The imaging findings are displayed along with a literature review. When it’s symptomatic, fibrous dysplasia could be revealed by common symptoms such as pain and bone deformity. Therefore, the radiologist plays a crucial role in diagnosis assessment, also in monitoring the lesion for early detection of complications especially malignant transformation.

Background: Congenital hyperinsulinism (CHI) is the most common of persistent hypoglycemia in infancy characterized by inappropriate insulin secretion in the presence of hypoglycemia. Objective: This case report evaluates the effect of Diazoxide treatmentin inducing pulmonary hypertension in a patient with hyperinsulinemic hypoglycemia. Case findings: A full-term baby male, birth weight 4.3kg, was born at 41 weeks gestation by emergency caesarean section due to fetal distress born in Al-Dawadmi Hospital. He developed convulsions started postnatally loaded with phenobarbitone then shifted to AL-Yamammah hospital as lifesaving case to be admitted in Neonatal ICU. He was found to have hyperinsulinemic hypoglycemia and started on Diazoxide. The patient readmitted in Pediatric ICUat age of 2 month with hypoxic respiratory failure. After evidence of pulmonary hypertension by Echocardiography, Diazoxide was held at 2nd day of admission but he developed recurrent attacks of hypoglycemia required Octreotide with intermittent glucagon. After 14 days, Echocardiographic study repeated and showed findings of non-obstructive hypertrophic cardiomyopathy with good systolic function and no evidences of pulmonary hypertension (PH). Conclusions: Pulmonary hypertension may be developed during Diazoxide therapy. Pulmonaryhypertension was evaluated by echocardiography at regular intervals. This complicationresolved once diazoxide has been withdrawn.

Supernumerary kidneys are defined by the presence of a 3rd or 4th kidney that is separate from the homolateral kidney and is served by a branch of a bifid ureter or a separate (double) ureter. These kidneys are poorly documented and extremely rare. These kidneys may be the site of lithiasis. We report here the ureteroscopic management of a pyelocalic lithiasis on a supernumerary kidney revealed by right low back pain in a woman.
