Abstract

Antimicrobial Resistance (AMR) is a global problem that causes increased morbidity, mortality, and healthcare costs. AMR arises from the irrational use of antibiotics in medicine and agriculture. This study aims to determine the profile of Gram-negative ESBL bacteria living in the cecum of broiler chickens. This study is a descriptive exploratory study using 5 chicken cecum samples taken from the Pagesangan market in Mataram city. The obtained bacteria were calculated by placing them on Macconkey agar media to count bacterial colonies. The results of this study showed that 20.1% of bacteria in the chicken cecum could grow on Macconkey media mixed with cefotaxime. Meanwhile, on Macconkey media without cefotaxime, 79.9% were obtained. Based on macroscopic, microscopic, and biochemical characteristics, it was found that the gram-negative bacteria obtained were Escherichia coli. In sensitivity tests, it was found that the bacteria were resistant to tetracycline (100%) and ampicillin (100%), and 25% were resistant to chloramphenicol. The conclusion is that gram-negative bacteria found in the cecum of broiler chickens, such as Escherichia coli, are resistant to several antibiotics. These bacteria are resistant to cefotaxime (20.1%), chloramphenicol (25%), tetracycline (100%), and ampicillin (100%).

Abstract

Precocious puberty is an endocrine disorder characterized by the premature development of secondary sexual characteristics, defined as occurring before the age of 8 in girls and 9 in boys. This literature review aims to understand precocious puberty: when childhood ends too soon. The article was compiled using a literature review method. Data were obtained through a search of various scientific sources, including international and national journals, textbooks, and clinical guidelines from the Indonesian Pediatrician Association (IDAI). Central precocious puberty, most often idiopathic in girls but associated with underlying pathology in boys, is caused by premature activation of the hypothalamic-pituitary-gonadal axis, while the peripheral form is caused by excess sex steroid production independent of gonadotropin stimulation. Clinical manifestations include early breast development, testicular enlargement, rapid linear growth, acne, and the early appearance of pubic or axillary hair. Diagnosis relies on a combination of careful history taking, physical examination, hormonal testing, bone age assessment, and imaging studies such as pelvic ultrasound or cranial MRI when indicated. Management strategies vary based on etiology, with gonadotropin-releasing hormone (GnRH) agonists being the standard treatment for central precocious puberty, while surgical or medical therapy is used for peripheral causes. In conclusion, precocious puberty is a childhood health issue of increasing concern due to its increasing global incidence. This condition not only impacts accelerated bone maturation and potential short stature in adulthood, but also impacts the child's psychological well-being and causes emotional distress to the family.

Abstract

Bilateral ureteral stones are a rare clinical manifestation of renal colic, obstructing urine flow, and can cause severe acute kidney injury (AKI) within hours. This case study aims to provide information regarding the diagnosis and management of bilateral ureteral stones causing acute kidney injury in a 52-year-old female patient. This case study uses a descriptive method to describe the current situation, for further analysis and interpretation. Based on anamnesis and physical examination, the patient was diagnosed with Acute Kidney Injury (AKI) stage 3 with a differential diagnosis of Advanced Chronic Kidney Disease (ACKD) stage 4. This condition is caused by urinary tract obstruction due to bilateral ureterolithiasis (stones in both ureters) and proximal right ureteral stenosis, which inhibits urine flow and worsens kidney function acutely and chronically. Complaints of right and left abdominal pain, as well as a history of urinary tract infections (UTIs) and hypertension, support the formation of stones in the urinary tract. The conclusion is that the patient Wirni/P/52 years old/AKI stage 3 dd ACKD stage 4 dt obstructive uropathy + ureterolithiasis infection + normocytic normochromic anemia dt chronic disease + bilateral ureteral stones + right proximal ureteral stenosis.

Abstract

The subtherapeutic use of antibiotics as Antimicrobial Growth Promoters (AGPs) in broilers has accelerated Antimicrobial Drug Resistance (AMR) in gut microbiota, posing a global threat. This study aimed to analyze the population, morphology, catalase test results, and antibiotic sensitivity of erythromycin and vancomycin to cefotaxime-resistant Gram-positive bacteria in the caecum of broilers from Mataram City slaughterhouses. Using exploratory descriptive method, five caecum samples were analyzed by Total Plate Count (TPC) on Man Rogosa Sharpe Agar (MRSA) media with and without cefotaxime, and incubated on Mannitol Salt Agar (MSA). Results revealed uniform bacterial morphology on MRSA (small, round, convex, entire edge, white, Gram-positive colonies) but varied morphologies on MSA. Catalase tests were negative on MRSA but mixed on MSA. Resistance to erythromycin and vancomycin was 80% on MRSA, while on MSA, erythromycin resistance reached 62.5% with variable vancomycin inhibition zones. The prevalence of cefotaxime-resistant bacteria was 5.24%. This study highlights diverse morphological, catalase, and antibiotic sensitivity profiles in cefotaxime-resistant bacteria, particularly on MSA. These findings underscore the need for stricter antibiotic use regulations and further research to mitigate AMR spread in poultry production.
