Pursuing Investigations Establish the Challenging Diagnosis of Primary Aldosteronism.

Primary aldosteronism is one of the causes of secondary hypertension. The most sensitive screening test for primary aldosteronism is the measurement of the plasma aldosterone concentration and plasma renin activity to calculate the aldosterone/renin ratio. We report a case of hypertension and hypokalemia with a negative plasma aldosterone/renin ratio, inconclusive confirmatory saline infusion test. Subsequently, the patient was diagnosed with primary aldosteronism secondary to adrenal adenoma. If there is a high index of clinical suspicion of primary aldosteronism, it is important to evaluate further to establish the diagnosis for initiation of specific treatment because failure to identify primary aldosteronism can lead to aldosterone-specific adverse cardiovascular diseases and events.

Evolving Challenges in Diagnosis of Renal Vasculitis.

Renal-limited vasculitis is a rare anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis that presents only with a renal manifestation in the absence of other organs involvement. In this report, a 50-year-old female presented with nonspecific symptoms and anemia, who was subsequently discovered to have renal-limited vasculitis. After receiving a combination of steroid and immunosuppressive therapy, she recovered uneventfully without further relapse. A wide range of nonspecific presenting symptoms and the insidious nature of renal disease often delay in early recognition of renal-limited vasculitis. Keeping a lower threshold of initiating vasculitis workup helps detect the earlier diagnosis which is crucial in management with improved renal outcome.

Mind the Localized Skeletal Pain: Chronic Recurrent Multifocal Osteomyelitis.

Chronic recurrent multifocal osteomyelitis (CRMO) is a rare idiopathic aseptic inflammatory bone disorder affecting primarily children and adolescents characterized by an insidious onset of pain, swelling, and tenderness over the affected bones. The clinical signs and symptoms of CRMO are nonspecific, radiological and histopathological tests are essential for its diagnosis. We present a case of an 18-year-old young man who was diagnosed with CRMO by a combination of clinical data, laboratory results, radiological imaging, and bone biopsy. The patient started anti-inflammatory and immunosuppressant therapy, and his lower extremity pain and swelling improved. This report highlights to investigate promptly in children and adolescents with chronic leg pain, to emphasize the importance of combined clinical, laboratory, and imaging tests for early identification, to have a greater understanding of the imaging appearance and increasing knowledge of this condition, which help shorten time to reach a diagnosis and prevent permanent osseous damage and long-term disabilities.

Medical management of coral reef aorta through optimised diuretic use and angiotensin receptor blockade.

Coral reef aorta (CRA) is a rare condition with potentially devastating complications. It is characterised by atherosclerotic calcification and stenosis of the visceral part of the aorta, usually occurring at the juxtarenal or suprarenal locations, and causing refractory hypertension and renal dysfunction. Surgical intervention, which is the recommended definitive treatment, is associated with significant morbidity and mortality. Endovascular stenting has been reported to be an alternative management option. To the best of our knowledge, this is the first case report to describe medical management of a patient with CRA with diuretics and angiotensin receptor blockade without surgical treatment.
