The Covid-19 pandemic has caused a decreasing number of non-Covid-19 inpatient visits in almost all hospitals, including the hospital where the study was conducted, which experienced decreasing Bed Occupancy Rate (BOR) up to 35.5%. This study aimed to identify the factors causing the decrease in the number of inpatients at the hospital. The research was conducted using a case study approach at a type D hospital in Malang Regency. Data was collected through a Focus Group Discussion (FGD) analyzed using a Fishbone Diagram combined with 5 whys and triangulation using secondary data and surveys. FGD respondents determined were eight respondents consisting of the Head of Inpatient Room, the Coordinator of Inpatient Room, the Coordinator of Outpatient, the Head of the Public Relations and Marketing Unit, and the Coordinator of the Admission Department. The results show that the causes can originate from human, method, market, and environmental aspects. Distrust in hospitals is caused by negative stigmatization and instructions to delay hospital services and communication barriers due to media as a consequence of implementing health protocols.
新冠肺炎大流行导致几乎所有医院的非新冠肺炎住院人数减少,包括进行研究的医院,床位入住率(BOR)下降了35.5%。本研究旨在找出导致医院住院人数减少的因素。这项研究是在玛琅摄政的一家D类医院采用个案研究方法进行的。数据是通过焦点小组讨论(FGD)收集的,使用鱼骨图结合5个原因和三角测量法使用二次数据和调查进行分析。FGD调查对象确定为8名调查对象,包括住院部主任、住院部协调员、门诊部协调员、公共关系和市场部主任以及住院部协调员。结果表明,其原因有人为因素、方法因素、市场因素和环境因素。对医院的不信任是由负面的污名化和延迟医院服务的指示以及由于执行卫生协议而造成的媒体沟通障碍造成的。

High nurse workload can impact the quality of hospital services. Nurses are the spearhead of the services, so they must obtain attention and be professionally managed to provide positive contributions to the advancement of the hospital. This study was conducted to describe the factors that influence the high workload of nurses in the Surgical and Internal Inpatient Installation (IRNA BDB) Baptis Batu Hospital. Qualitative and quantitative study methods with an explorative, descriptive approach were used. Determination of the root of the problem was using the fishbone diagram. Factors that influence the high workload of inpatient nurses are the number of nurses that do not meet the workload needs, placement of junior nurses and interns increases more workload for senior nurses, nurses carry out financial administrative tasks, blood sampling for laboratory examinations, and dispensing sterile preparations, as well as nurse call and bathroom facilities that are not supportive. In short, the causes of the high nurse workload are the lack of nurses, varied nurse qualities, non-nursing workloads, and less supportive facilities.
护士的高工作量会影响医院的服务质量。护士是服务的先锋队,必须得到重视和专业管理,为医院的发展做出积极贡献。本研究旨在探讨巴蒂斯巴图医院外科及内科住院装置(IRNA BDB)护士高工作量的影响因素。采用探索性、描述性的定性和定量研究方法。用鱼骨图确定问题的根源。影响住院护士高工作量的因素有:护士数量不能满足工作量需求,初级护士和实习生的安置增加了高级护士的工作量,护士承担财务管理任务,实验室检查采血和分发无菌制剂,以及护士呼叫和浴室设施不支持。简而言之,造成护士工作量高的原因是缺乏护士、护士素质参差不齐、非护理工作量和辅助设施较少。

The Emergency Department (ED), as the main entrance of health service access in hospitals, faces the highest infection risk and high service load due to the increasing number of patients during the Covid-19 pandemic. Implementing a pre-triage system offers a solution to deal with a surge in the number of patients who demand staff preparedness. This study aimed to determine the knowledge level on the pre-triage system and its relationship with the preparedness of emergency room staff in implementing the pre-triage system. The study was conducted with a cross-sectional approach in a private type C hospital in Malang District on all 30 ER staff as respondents. The research instrument used were questionnaires. Data analysis was done using descriptive analysis and the Fisher exact test. The results show that although 76.7% of respondents have insufficient knowledge, 86.7% of respondents are ready to implement the pre-triage system. The test results prove that there is no relationship between the knowledge and the preparedness levels of the emergency room staff in implementing the pre-triage system.

Functional Endoscopic Sinus Surgery (FESS) is commonly performed on patients with chronic rhinosinusitis (CRS) that has not improved through medical treatment. Hyaluronic acid (HA) has a vital role in wound healing and mucosa repair. This study aimed to determine the effectiveness of nasal drops using HA on clinical symptom scores, quality of life, and endoscopic features in post-FESS patients. This study was conducted with a pre- and post-test randomized control group design in 50 CRS patients undergoing FESS (25 males, 25 females, aged 18 to 55 years) at Dr. Kariadi General Hospital Medical Center Semarang from May to November 2019. The treatment group received additional HA therapy, while the control group only received standard therapy. Subjects were assessed with clinical symptom scores, quality of life, and endoscopic features before and after treatment. The statistical analysis was performed between the control and treatment groups using the Mann-Whitney test. There were significant differences between the control and treatment groups on clinical symptom scores (nasal congestion p = 0.001, runny nose p = 0.027) and endoscopic features (edema p = 0.001, secret p = 0.001, crusts p = 0.001). The therapy in post-FESS patients was using nasal drops, the treatment group was given HA, and the control group was given a placebo. Nasal drops using HA in the treatment group show improvement in clinical symptom scores of nasal congestion and runny nose, as well as the endoscopic appearance of edema, secret, and crusts.
功能性内窥镜鼻窦手术(FESS)通常用于慢性鼻窦炎(CRS)患者,这些患者没有通过药物治疗得到改善。透明质酸在伤口愈合和粘膜修复中起着至关重要的作用。本研究旨在确定HA滴鼻液对fess后患者临床症状评分、生活质量和内窥镜特征的有效性。本研究采用测试前和测试后随机对照组设计,于2019年5月至11月在三宝朗Dr. Kariadi综合医院医疗中心进行了50例接受FESS的CRS患者(25男,25女,18至55岁)。治疗组在治疗的基础上给予HA治疗,对照组仅给予标准治疗。在治疗前后对受试者进行临床症状评分、生活质量和内窥镜特征评估。采用Mann-Whitney检验对对照组和治疗组进行统计学分析。对照组与治疗组在临床症状评分(鼻塞p = 0.001,流鼻涕p = 0.027)和内窥镜特征(水肿p = 0.001,隐匿p = 0.001,结痂p = 0.001)上差异有统计学意义。fess后患者给予滴鼻液治疗,治疗组给予透明质酸,对照组给予安慰剂。治疗组使用透明质酸滴鼻液鼻塞、流鼻涕的临床症状评分改善,内窥镜下出现水肿、积液、结痂等症状。

Hemorrhoids are a common anorectal disease and can affect all ages. This research aims to specify the differences in Length of Stay (LOS) of hemorrhoidal patients who underwent a modified combined method of rubber ligation and sclerotic injection using Paran Injection Ligation for Ambeien pack (PILA pack) compared to a hemorrhoidectomy. This study consisted of 56 respondents who underwent hemorrhoidectomy, and the other 56 respondents experienced a modified combined method of rubber ligation and sclerotic injection using a PILA pack. Data showed the LOS's average of respondents who underwent hemorrhoidectomy was 47.33 hours or 1.97 days. Meanwhile, respondents' average length of stay who underwent a modified combined rubber ligation and sclerotic injection using a PILA pack was 20.44 hours or 0.85 days. Finally, the T-test results showed a p-value of 0.001 (p<0.05), indicating that there was a statistically significant difference in the average LOS between hemorrhoidal patients who underwent hemorrhoidectomy and hemorrhoidal patients who underwent a modified combined method of rubber ligation and sclerotic injection using PILA pack. Based on the result, it can be concluded that the mean LOS for hemorrhoidal patients receiving haemorrhoidectomy vs. hemorrhoidal patients undergoing a modified technique of rubber ligation and sclerotic injection utilizing the Paran Injection Ligation for Ambeien pack was significantly different.
痔疮是一种常见的肛肠疾病,可影响所有年龄。本研究旨在明确采用改良的橡胶结扎和硬化注射联合方法,使用Paran注射结扎进行Ambeien pack (PILA pack)与痔疮切除术相比,痔疮患者的停留时间(LOS)的差异。这项研究包括56名接受痔疮切除术的应答者,另外56名应答者使用PILA包进行橡胶结扎和硬化注射的改良联合方法。数据显示,接受痔疮切除术的受访者的LOS平均为47.33小时或1.97天。同时,接受改良的橡胶结扎和使用PILA包进行硬化注射的应答者的平均停留时间为20.44小时或0.85天。最后,t检验结果显示p值为0.001 (p<0.05),表明行痔切除术的痔疮患者与改良橡胶结扎与PILA包硬化注射联合方法的痔疮患者平均LOS差异有统计学意义。基于结果,我们可以得出结论,接受痔疮切除术的痔疮患者与采用改良的橡胶结扎和硬化注射技术的痔疮患者的平均LOS存在显著差异。

Paradoxical Sleep Deprivation (PSD) elevates glucocorticoid and Reactive Oxygen Species (ROS) levels that cause oxidative stress, trigger spermatogenic cells damage, and reduce the number of sertoli cells. Vitamin C and E are antioxidants that could prevent spermatogenesis damage by preventing free radical formation. The study aimed to determine the effect of single and combined doses of vitamin C and E in improving spermatogenesis of white male rats (Rattus norvegicus) model of PSD. This is experimental research with post-test only and control group design on 28 white male rats distributed into four groups, i.e. group I (control, PSD), group II (PSD+vitamin C), group III (PSD+vitamin E), and group IV (PSD+a combination of vitamin C and E). Testicular preparations were stained using Hematoxylin-Eosin staining, quantitative scores of spermatogenic cells were measured using the Johnsen method, and the number of sertoli cells was counted in 10 seminiferous tubules in each of the three testicular sections. Group I has the lowest mean of Johnsen score (5.27±0.28), and group IV has the highest mean score (8.95±0.62), while the Mann-Whitney test showed a significant difference (p<0.05) between group II, III and IV compared to group I (control group). Mean sertoli cells number of group I is the lowest (10.66±1.04), and group IV has the highest sertoli cells number. The post-hoc LSD test showed a significant difference (p<0.05) between group IV and the other groups. Thus, the combination of vitamins C and E improves Johnsen score and sertoli cells number of male rats (Rattus norvegicus) experiencing PSD.
矛盾睡眠剥夺(PSD)会升高糖皮质激素和活性氧(ROS)水平,导致氧化应激,引发生精细胞损伤,减少支持细胞数量。维生素C和E是抗氧化剂,可以通过阻止自由基的形成来防止精子形成的损害。本研究旨在探讨单剂量和联合剂量维生素C和E对白种雄性大鼠PSD模型精子发生的影响。本实验以28只雄性白种大鼠为实验对象,采用后测和对照组设计,将其分为4组,即I组(对照组,PSD)、II组(PSD+维生素C)、III组(PSD+维生素E)和IV组(PSD+维生素C和E的组合)。睾丸制剂采用苏木精-伊红染色,生精细胞采用Johnsen法定量评分。在睾丸三段各10个精管中计数支持细胞的数量。实验组约翰森评分平均值最低(5.27±0.28),实验组最高(8.95±0.62),经Mann-Whitney检验,实验组、实验组、实验组与对照组比较差异有统计学意义(p<0.05)。I组平均支持细胞数最少(10.66±1.04)个,IV组平均支持细胞数最多。经事后LSD检验,IV组与其他组比较差异有统计学意义(p<0.05)。由此可见,维生素C和E联合使用可提高PSD雄性大鼠(Rattus norvegicus)的Johnsen评分和支持细胞数量。

Testicular preparations were stained using Hematoxylin-Eosin staining, quantitative scores of spermatogenic cells were measured using the Johnsen method, and the number of sertoli cells was counted in 10 seminiferous tubules in each of the three testicular sections. Group I has the lowest mean of Johnsen score (5.27±0.28), and group IV has the highest mean score (8.95±0.62), while the Mann-Whitney test showed a significant difference (p<0.05) between group II, III and IV compared to group I (control group). Mean sertoli cells number of group I is the lowest (10.66±1.04), and group IV has the highest sertoli cells number. The post-hoc LSD test showed a significant difference (p<0.05) between group IV and the other groups. Thus, the combination of vitamins C and E improves Johnsen score and sertoli cells number of male rats (Rattus norvegicus) experiencing PSD.","PeriodicalId":17705,"journal":{"name":"Jurnal Kedokteran Brawijaya","volume":"63 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73200445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An epidermoid cyst is benign cystic tumor coated with squamous epithelium and contains keratin. It generally appear on the body parts which have pilosebaceous follicles, such as head, neck, and body. The manifestation of the disease is a skin-colored, mobile, painless nodule with a punctum in the center. Epidermoid cyst of sole is often similar to clavus, callus, and verruca plantaris. However, epidermoid cyst of sole is rare because the area is without pilosebaceous follicles. The etiopathology is believed due to trauma that causes implantation of epidermal cells into the dermis layer, thus triggering the formation of epidermoid cysts. This case report a girl with an epidermoid cyst of sole that was initially thought as a verruca plantaris and clavus. A 14-year-old girl complained about a bump on her right foot that got bigger during nine months. The lesions surface was slippery, and the patient felt pain when walking. The patient denied any trauma or changing footwear with friends or relatives. Examination in the right lateral plantar pedis region, a nodule was found skin-colored, round, measuring 2x2 cm, and solitary. The patient was planned to undergo excochleation, but since a white cystic mass was found during the operation, it was continued with extirpation surgery. The histopathological examination results showed a stroma with keratin, which was concluded as an epidermoid cyst. In the case of epidermoid cysts with atypical clinical symptoms and unusual lesion locations, histopathological examination is required for a definite diagnosis.
表皮样囊肿是一种包被鳞状上皮并含有角蛋白的良性囊性肿瘤。它通常出现在有毛囊皮脂腺的身体部位,如头部、颈部和身体。本病表现为皮肤颜色、可移动、无痛的结节,中心有一个小点。足底表皮样囊肿常与锁骨癣、愈伤组织和植物疣相似。然而,足底表皮样囊肿是罕见的,因为该区域没有毛囊皮脂腺毛囊。病因被认为是由于外伤导致表皮细胞植入真皮层,从而引发表皮样囊肿的形成。本病例报告一个女孩的脚底表皮样囊肿,最初被认为是植物和锁骨疣。一名14岁的女孩抱怨说,她右脚上的肿块在9个月内变得更大了。病变表面湿滑,患者行走时疼痛。病人否认有任何创伤或与朋友或亲戚换鞋。检查右侧足底外侧,发现一结节,皮肤色,圆形,2x2 cm,单发。患者原计划行摘除手术,但手术中发现白色囊性肿块,继续行摘除手术。组织病理学检查显示间质有角蛋白,为表皮样囊肿。对于临床症状不典型、病变部位不寻常的表皮样囊肿,需要组织病理学检查才能明确诊断。

Restraint stress causes changes in the brain parameters. Little research has been done on the impact of restraint stress on other tissues, including adrenal glands and kidneys. This study aimed to determine the effect of restraint stress on eating behaviors, depressive-like, anxiety-like behaviors, weight gain as well as histopathological changes in the kidneys and adrenal glands. Twenty adult BALB/c mice were assigned into control male, stressed male, control female, and stressed female. Restraint stress was applied two hours/day for 14 days. Tail suspension and open field tests were carried out to perform behavior analyses. Adrenal and kidney histological slides were observed under an Olympus CX-31 microscope and visualized using an Olympus E330 camera. The two-way ANOVA test was used for statistical analysis using GraphPad Prism 9.0.0 software. We found that restraint stress defeat appetite and reduces weight gain particularly in stressed female. However, depressive- and anxiety-like behavior were demonstrated in both sexes. Adrenal and kidney tissues of stressed mice demonstrated a higher number of necrotic cells than control. The pyknosis phase was more common than the karyorrhexis and karyolitic phases. Interestingly, male mice were more receptive to stress than female mice. These findings indicate that restraint stress leads to behavioral changes and cellular defects in the adrenal glands and kidneys, particularly in male mice. The sympathetic activation and hypothalamus-pituitary-axis stimulation are assumed as the underlying stress effect of the restraint procedure. The restraint stress method has the potential to be used in future research on stress-responsive target organs.
克制压力会引起大脑参数的变化。关于约束压力对其他组织(包括肾上腺和肾脏)的影响的研究很少。本研究旨在确定约束应激对饮食行为、抑郁样行为、焦虑样行为、体重增加以及肾脏和肾上腺的组织病理学变化的影响。将20只成年BALB/c小鼠分为对照雄性、应激雄性、对照雌性和应激雌性。施加约束应力2 h /d,连续14 d。进行了尾悬架和露天试验,以进行性能分析。在奥林巴斯CX-31显微镜下观察肾上腺和肾脏组织学切片,并使用奥林巴斯E330相机进行可视化。采用GraphPad Prism 9.0.0软件,采用双因素方差分析进行统计分析。我们发现,抑制压力能抑制食欲,减少体重增加,尤其是压力大的女性。然而,类似抑郁和焦虑的行为在两性中都有表现。应激小鼠的肾上腺和肾脏组织坏死细胞数量高于对照组。固缩期比核分裂期和核成核期更常见。有趣的是,雄性老鼠比雌性老鼠更容易接受压力。这些发现表明,约束压力会导致肾上腺和肾脏的行为改变和细胞缺陷,尤其是在雄性小鼠中。交感神经的激活和下丘脑-垂体轴的刺激被认为是约束过程的潜在应激效应。约束应力法在未来的应激反应靶器官研究中具有广阔的应用前景。

The elderly often have nutritional problems. The risk of malnutrition can stimulate the prevalence of frailty and declining cognitive function in the elderly. The study aimed to analyze the relationship between nutritional status, frailty, and cognitive function in the elderly at Dr. H. Moch. Ansari Saleh Hospital Banjarmasin. This study was analytic observational using a cross-sectional method. A sample of 93 elderly was obtained using a total sampling technique according to the inclusion and exclusion criteria. The nutritional status assessment was done using the Mini Nutritional Assessment-Short Form (MNA-SF), the Edmonton Frailty Scale (EFS), and the Mini-Mental State Examination (MMSE). The results showed that the mean of Mini Nutritional Assessment score was 12.00±2.126, the average frailty score was 4.41±1.872, and the average value of cognitive function was 25.98±2.923. Data were analyzed using the Spearman's non-parametric correlation test with a 95% confidence level. The correlation test results between nutritional status and frailty obtained p=0.000 and r=-0.490. The correlation test results between nutritional status and cognitive function obtained p=0.000 and r=0.595. In short, there is a relationship between nutritional status on frailty and cognitive function in the elderly at Dr. H. Moch. Ansari Saleh General Hospital Banjarmasin, it means that the good nutritional status in the elderly, the risk of frailty syndrome will decrease and improve cognitive function.
