The case revolves around a middle-aged Black woman diagnosed with type 2 diabetes six years prior, who presents with new neurological, dermatological, and systemic symptoms. Analyzing her history, physical findings, and laboratory results allows a comprehensive understanding of her condition and guides appropriate clinical management.

Introduction

Type 2 diabetes mellitus (T2DM) is a prevalent metabolic disorder characterized by insulin resistance and relative insulin deficiency, leading to chronic hyperglycemia. Proper evaluation of newly emergent symptoms in diabetic patients is essential for preventing complications and optimizing care. This case involves a woman with longstanding T2DM presenting with neuromuscular weakness, dermatological issues, and systemic symptoms that warrant detailed clinical and laboratory assessment. Key aspects include questioning her symptoms, understanding her personal, familial, and medical history, performing thorough physical examinations, and ordering targeted tests to facilitate accurate diagnosis and management.

Symptom Inquiry and Clinical Considerations

In addressing her symptoms of right foot weakness and pruritic rash, several pertinent questions are vital. Firstly, for her foot weakness, questions should explore onset, progression, associated symptoms such as numbness or tingling, and factors like pain or gait disturbances. Determining whether she experiences episodes of sudden weakness or sensory loss could suggest neurological ischemic events or peripheral neuropathies. It is also critical to assess for any muscle cramps, fasciculations, or weakness in other limbs to identify potential neuromuscular disorders.

Regarding her itching rash, questions should encompass duration, pattern, aggravating or relieving factors, and the presence of similar rashes elsewhere, such as her armpits and beneath her breasts. Clarifying whether the rash is associated with systemic symptoms like fever or malaise aids differentiation between infectious, fungal, or dermatitis causes. The effect of weather, relief with salt baths, and previous occurrences are important, hinting at possible dermatophyte infections or intertrigo in humid conditions.

Importantly, exploring her systemic symptoms—such as increased thirst, nocturia, and eye discomfort—can elucidate her glycemic control status and potential complications like dehydration or diabetic retinopathy. Her history of weight gain and dietary habits, alongside the duration since diagnosis, informs the risk of complications and control challenges.

Personal and Family Medical History Inquiry

Understanding her personal and familial health background is crucial. Questions should target the timeline of her diagnosis, initial management, and adherence. Given her history of inadequate follow-up, exploring barriers to care related to socioeconomic status, health literacy, or access is significant. Her family history of diabetes (mother and sister diagnosed in their 40s) suggests a strong genetic component, which influences screening and risk stratification.

Additional questions should address other comorbidities like hypertension, dyslipidemia, cardiovascular disease, and obesity, which are commonly associated with T2DM. Evaluating her medication adherence, lifestyle modifications, and psychosocial factors further refines her management plan. Screening for microvascular and macrovascular complications is indicated, especially considering her symptoms and physical findings.

Medical History and Risk Factor Assessment

In detail, her historical data such as her initial blood glucose levels around 200 mg/dL, and her current HbA1c of 9.1%, indicate poor glycemic control, increasing her risk for complications. Her dietary habits—high in fats and refined sugars—along with minimal exercise, contribute to obesity and insulin resistance. We should investigate her history of dyslipidemia, hypertension, and previous episodes or signs of diabetic neuropathy or retinopathy.

Additional queries might include history of smoking, alcohol use, medication side effects, or episodes of hypoglycemia, to refine her overall health picture and tailor interventions accordingly.

Physical Examination and Findings

The physical exam reveals obesity with a blood pressure of 162/98 mm Hg, suggesting poorly controlled hypertension, an important cardiovascular risk factor. Dermatological findings include erythematous moist rashes in intertriginous areas, along with hyperpigmented spots on her shins, indicating acanthosis nigricans, a marker of insulin resistance. The rash in her groin, armpits, and beneath her breasts could be intertrigo or candidiasis, common in diabetics due to hyperglycemia and moisture.

Neurologically, she demonstrates a foot drop (dorsiflexion 2/5), sensory deficits on the soles, diminished reflexes, and gait disturbance—consistent with peripheral neuropathy. The absence of cerebellar signs and negative Romberg test suggest localized neuropathy without central involvement. The diminished arterial pulses reflect peripheral vascular disease, another common complication.

Ophthalmological examination noting mild arteriolar narrowing suggests hypertensive or diabetic retinopathy. Cardiac auscultation reveals distant heart tones, possibly indicating pericardial or cardiovascular compromise, which are typical in longstanding uncontrolled diabetes.

Significant Physical Findings

• Moist intertriginous rash indicating candidiasis or dermatitis
• Acanthosis nigricans on shins indicating insulin resistance
• Right foot drop with dystrophic weakness and sensory deficits
• Obesity and hypertension indicating cardiovascular risk
• Decreased peripheral pulses indicating arterial disease

Laboratory Tests and Rationale

Given her hyperglycemia, neuropathy signs, and systemic symptoms, targeted laboratory assessment is essential. Tests should include:

• Complete blood count (CBC) to evaluate for infection or anemia
• Fasting blood glucose and lipid profile to assess glycemic control and cardiovascular risk factors
• Serum HbA1c to measure long-term glycemic management
• Serum electrolytes, BUN, and creatinine to assess renal function
• Lipid panel to evaluate dyslipidemia
• Urinalysis for microalbuminuria, proteinuria, and infection
• Fungal culture or KOH prep from rash sites to confirm dermatophyte/yeast infection
• Additional tests such as nerve conduction studies, if indicated for neuropathy evaluation
• Retinal examination to assess diabetic retinopathy progression

These investigations will provide insights into her glycemic control, complications, and infections, guiding comprehensive management.

Discussion and Implications for Management

The patient’s presentation highlights the multifaceted nature of diabetes complications, particularly peripheral neuropathy, dermatological infections, and cardiovascular risks. Her poor glycemic control (HbA1c 9.1%) requires intensification of pharmacotherapy, possibly including insulin therapy, given her lifestyle and compliance challenges. Lifestyle modifications emphasizing weight loss, dietary improvements, and increased physical activity are critical.

Addressing her hypertension with appropriate antihypertensives, and controlling dyslipidemia, reduces macrovascular complication risks. Management of dermatophytic infections involves antifungal treatments and improved hygiene. Glycemic control will also facilitate neuropathy management and potentially improve her foot weakness.

Regular screening for diabetic retinopathy and nephropathy should be instituted, alongside patient education on foot care and infection prevention. Multidisciplinary care involving endocrinologists, podiatrists, dermatologists, and ophthalmologists enhances outcomes and quality of life.

Conclusion

This case exemplifies the importance of thorough clinical evaluation and targeted testing in patients with longstanding diabetes presenting with new complaints. Comprehensive management should focus on optimizing glycemic control, addressing comorbidities, and preventing complications through patient-centered, multidisciplinary approaches.
