<![CDATA[Gastroesophageal Reflux Disease (GERD) is a chronic gastrointestinal disorder resulting from the retrograde movement of gastric contents into the esophagus, often due to lower esophageal sphincter dysfunction. It is characterized by hallmark symptoms such as heartburn, regurgitation, epigastric pain, and may also present with extra-esophageal manifestations including chronic cough, hoarseness, or dental erosion. GERD significantly affects quality of life and, if left untreated, may lead to complications such as esophagitis, strictures, or Barrett’s esophagus. This case report presents a 21-year-old female with a history of recurrent GERD symptoms since childhood. She presented with complaints of persistent epigastric pain, nausea, and a burning sensation in the chest, particularly after meals. Physical examination revealed epigastric tenderness and clinical signs suggestive of anemia, including pallor and fatigue. A detailed clinical history and symptom pattern strongly supported a diagnosis of GERD. Given the classic presentation and absence of alarm features, a non-invasive, symptom-based diagnostic approach was adopted, avoiding the need for endoscopy or pH monitoring. The patient was managed with a combination of pharmacological therapy omeprazole (a proton pump inhibitor), antacids for symptomatic relief, paracetamol for pain management, and vitamin B6 to address nutritional deficiencies. Additionally, lifestyle modifications were emphasized, including dietary regulation, avoidance of trigger foods (such as spicy and acidic items), elevation of the head during sleep, and meal timing adjustments. Within one week of initiating treatment, the patient reported significant improvement in symptoms, with reduced frequency and intensity of heartburn and nausea. This case highlights the importance of early recognition and comprehensive management of GERD, especially in young adults with a chronic history of symptoms. It underscores the effectiveness of combining pharmacological treatment with lifestyle interventions and demonstrates that a symptom-based, non-invasive approach can be both practical and effective in primary care settings. Patient education and adherence to therapy remain critical in preventing recurrence and improving long-term outcomes.]]>

<![CDATA[Bilateral knee osteoarthritis is a progressive degenerative joint condition frequently observed in the elderly and often complicated by comorbid hypertension, which can exacerbate systemic inflammation and impair functional outcomes. This case report presents a 71-year-old woman with acute worsening of bilateral knee pain and restricted flexion over three days, accompanied by neck discomfort. Her medical history included longstanding hypertension and a positive maternal family history of the same condition. A holistic, family-medicine–based assessment revealed interacting biomedical factors (pain, limited mobility, elevated blood pressure), psychological concerns related to fear of functional decline, adequate family and social support, and environmental-behavioral contributors affecting daily activities. The patient underwent integrated management consisting of patient education, lifestyle modification, joint-protective behavior counseling, and tailored low-intensity physical exercise. Pharmacological therapy included sodium diclofenac 50 mg, amlodipine 5 mg, dexamethasone 0.5 mg, and pyridoxine HCl. Follow-up evaluation demonstrated reduced pain intensity, improved knee mobility, better hypertension control, and enhanced disease understanding, indicating positive response to combined biomedical and holistic interventions. This report aims to document the identification, management, and clinical progression of bilateral knee osteoarthritis with comorbid hypertension using a structured family medicine approach. A literature review indicates that osteoarthritis progression in the elderly is commonly influenced not only by degenerative aging processes and obesity but also by comorbidities such as hypertension, which may worsen joint microcirculation, increase inflammatory mediators, and accelerate cartilage degradation. The novelty of this report lies in the integration of a comprehensive holistic assessment encompassing biomedical, psychological, social, and behavioral dimensions into the management plan, demonstrating its measurable impact on short-term clinical improvement. This case underscores that elderly patients with coexisting osteoarthritis and hypertension benefit significantly from an interdisciplinary, patient-centered model of care. The findings support that early holistic intervention may optimize functional capacity, enhance self-management, and potentially slow the progression of disability, offering valuable insights for future community-based geriatric care frameworks.]]>

<![CDATA[Acute gastroenteritis remains one of the most common acute conditions in children and adolescents, frequently leading to dehydration and requiring prompt clinical assessment to prevent further complications. Although management guidelines are well established, variability in presentation and progression highlights the importance of individualized and holistic diagnostic approaches in primary care. This report describes a case involving a 13-year-old male who presented with severe gastrointestinal symptoms, including diarrhea exceeding ten episodes per day over three consecutive days, more than five episodes of vomiting, abdominal pain, fever, and generalized weakness. Clinical examination demonstrated a weakened overall condition, blood pressure of 100/70 mmHg, pulse 85 beats per minute, respiratory rate 20 breaths per minute, temperature 36.7°C, and signs consistent with mild to moderate dehydration. Laboratory evaluation revealed slightly decreased leukocyte levels, suggesting a likely viral etiology. The management in this case reflects the methodological core of the intervention: a holistic, stepwise approach integrating intravenous rehydration, symptomatic therapy, and adaptive pharmaceutical adjustments based on evolving clinical features. The patient was administered Ringer’s Lactate intravenously through a loading dose followed by controlled infusion at 25 drops per minute. Antiemetic therapy with ondansetron, antipyretics, antacids, attapulgite, and oral rehydration solution were provided initially. On the second day, antibiotics and ranitidine were introduced in response to persistent gastrointestinal complaints and to prevent potential secondary complications. The results demonstrated clear clinical improvement within 72 hours, marked by decreased diarrhea frequency, cessation of vomiting, and normalization of vital signs (blood pressure 100/65 mmHg; pulse 80 beats per minute). Hydration status returned to normal, and no complications or referral indications were identified. This case underscores the conclusion that integrating holistic assessment with tailored rehydration strategies and selective pharmacologic therapy can produce rapid and effective recovery in pediatric acute gastroenteritis. The novelty lies in demonstrating how a dynamic, symptom-guided model of care in a primary health setting can optimize outcomes while minimizing unnecessary escalation of treatment.]]>

<![CDATA[Hypertension remains a major global health challenge and a leading contributor to cardiovascular morbidity and mortality. Its asymptomatic nature causes many individuals to remain undiagnosed, increasing the risk of severe complications such as stroke, coronary artery disease, and renal impairment. Despite advancements in diagnostic and therapeutic approaches, hypertension awareness and treatment adherence remain low, particularly in primary care settings where early detection is crucial. This study describes the clinical identification and management process of a hypertensive adult patient at Segala Mider Public Health Center as an illustration of the essential role of primary healthcare services in improving hypertension control at the community level. Clinical data were collected through patient interviews, vital sign assessment, physical examination, and review of medical records. The patient, a 42-year-old male, presented with recurrent dizziness triggered by physical activity and consumption of sweet foods. Initial evaluation showed severely elevated blood pressure at 164/122 mmHg with otherwise normal cardiopulmonary findings. The patient had previously been taking amlodipine 5 mg daily with suboptimal response. Management involved titration of amlodipine to 10 mg daily for 15 days, accompanied by short-term furosemide therapy and vitamin B complex supplementation. The intervention produced symptomatic improvement and facilitated better blood pressure control during follow-up. The findings highlight the importance of timely recognition of uncontrolled hypertension, appropriate pharmacological adjustment, and continuous monitoring. This report emphasizes the relevance of primary care in initiating evidence-based treatment, identifying modifiable risk factors, and ensuring patient education regarding lifestyle modification. The novelty of this study lies in demonstrating how structured evaluation and treatment optimization in a resource-limited primary care setting can effectively support hypertension control while preventing long-term complications, reinforcing the vital role of frontline healthcare facilities in managing chronic diseases.]]>

<![CDATA[Acute gastritis is a common gastrointestinal disorder characterized by sudden inflammation of the gastric mucosa, frequently associated with dietary irritation, psychological stress, and dysregulation of gastric acid secretion. Although generally considered a benign and self-limiting condition, acute gastritis may significantly impair daily functioning, particularly among young adults with irregular lifestyles. This article describes the clinical course and holistic management of acute non-erosive gastritis in a young adult, emphasizing the contribution of modifiable behavioral and psychosocial factors. A 24-year-old woman presented to a primary healthcare facility with a four-day history of epigastric burning and pressing pain, aggravated by delayed meals and the consumption of spicy and acidic foods. The patient reported irregular eating patterns and considerable academic- and work-related psychological stress. There was no history of NSAID use, alcohol consumption, smoking, or previous gastrointestinal disease. Clinical assessment was conducted through structured history taking, comprehensive physical examination, and anthropometric measurement. No laboratory or endoscopic investigations were initially performed due to the absence of alarm features. The diagnosis of acute non-erosive gastritis was established based on clinical criteria. Management consisted of an integrated approach combining pharmacological and non-pharmacological interventions. Pharmacological therapy included omeprazole 20 mg once daily to suppress gastric acid secretion and antacids administered as needed for symptomatic relief. Non-pharmacological management focused on patient and family education regarding gastric-friendly dietary patterns, regular meal timing, avoidance of trigger foods and beverages, and stress management strategies. Follow-up evaluation was planned to monitor symptom resolution and determine the need for further diagnostic investigations, including Helicobacter pylori testing or endoscopy, if symptoms persisted or worsened. Following the initiation of combined therapy and lifestyle modification, the patient demonstrated clinical improvement with reduced frequency and intensity of epigastric pain. This case underscores the importance of addressing lifestyle and psychosocial contributors in addition to pharmacological treatment in acute gastritis. The novelty of this report lies in its explicit integration of holistic clinical assessment including functional, psychological, and family-based factors within the management of acute gastritis in a young adult, highlighting a practical, patient-centered model that may reduce symptom recurrence and improve long-term outcomes in primary care settings.]]>
