ABSTRACT

The aim of this study is to characterise somatostatin analogue-responsive headache in acromegaly, hitherto not systematically documented in a significant cohort. Using the UK pituitary network, we have clinically characterised a cohort of 18 patients suffering from acromegaly-related headache with a clear response to somatostatin analogues. The majority of patients had chronic migraine (78%) as defined by the International Headache Society diagnostic criteria. Headache was present at the time of acromegaly presentation and clearly associated temporally with disease activity in all cases. Short-acting somatostatin analogues uniquely resolved pain within minutes and the mean duration of analgesia was 1-6 h. Patients on long-acting analogues required less short-acting injections (mean: 3.7 vs 10.4 injections per day, P = 0.005). 94% used somatostatin analogues to control ongoing headache pain. All patients presented with macroadenoma, most had incomplete resection (94%) and headache was ipsilateral to remnant tissue (94%). Although biochemical control was achieved in 78% of patients, headache remained in 71% of them. Patients selected for this study had ongoing headache post-treatment (mean duration: 16 years after diagnosis); only four patients reached headache remission 26 years (mean range: 14-33) after the diagnosis. Headache in acromegaly patients can be persistent, severe, unrelieved by surgery, long-lasting and uncoupled from biochemical control. We show here that long-acting analogues allow a decrease in the number of short-acting analogue injections for headache relief. Further studies are needed to understand the mechanisms, markers and tumour tissue characteristics of acromegaly-related headache. Until then, this publication serves to provide the clinical characteristics as a reference point for further study.

ABSTRACT

BACKGROUND: Polyarteritis nodosa (PAN) is a medium vessel vasculitis which causes significant morbidity and mortality. Usually, it presents with constitutional symptoms with angiographic evidence of aneurysms or segmental stenosis of arteries of mesenteric or renal vasculature. It is exceedingly uncommon for PAN to present with symptomatic progressive intermittent claudication. CASE PRESENTATION: We describe a 60-year-old male who presented with rapidly progressive intermittent claudication of his right leg. He did not have any significant atherosclerotic risk factors. He had recent onset hypertension and loss of weight. He also had mononeuropathy of right common peroneal nerve and livedo reticularis rash. With negative autoimmune markers and suggestive histology in deep punch skin biopsy and angiographic evidence of segmental stenosis of femoral and renal arteries, we diagnosed PAN. We treated him with aggressive immunosuppressants and vascular bypass surgery of right femoral vessels; he showed a good response. CONCLUSION: Rapidly progressive unilateral intermittent claudication could be a very rare, but noteworthy presentation of PAN. With suggestive histology and exclusion of other comorbidities aggressive immunosuppressants should be instituted. Vascular bypass surgery for critical ischaemia of the limbs is an option that could be considered for limb-threatening disease.

ABSTRACT

BACKGROUND: At the time of diagnosis, Multiple Myeloma is commonly associated with renal impairment. Renal tubular acidosis without overt renal insufficiency is an uncommon disease presentation of myeloma. Among tubular acidosis types, isolated renal tubular acidosis is a very unusual presentation of multiple myeloma. CASE PRESENTATION: We present a 55 years old female who presented with lower limb weakness due to persistent hypokalaemia caused by distal renal tubular acidosis. On further investigation of her anaemia with high erythrocyte sedimentation rate, we diagnosed IgG myeloma. CONCLUSION: Isolated distal renal tubular acidosis is a rare presentation of multiple myeloma. In the absence of hypercalciuria and demonstrable light chain excretion in urine, we assumed that the distal renal tubular acidosis could have been caused by monoclonal hypergammaglobulinaemic state of multiple myeloma.

ABSTRACT

BACKGROUND: Tricyclic antidepressants (TCA) are becoming one of the most frequently used substances in self poisoning. Significant morbidity and mortality associated with TCA overdose are often related to and refractory hypotension. We report the first case of survival after severe amitriptyline poisoning, leading to prolonged cardiac arrest and ventricular tachycardia (VT), resuscitated with 3 h of uninterrupted cardiac massage and Direct current (DC) shocks. CASE PRESENTATION: A 25 year old girl presented with severe amitriptyline poisoning causing pulseless VT and prolonged cardiac arrest. After 3 h of uninterrupted external cardiac massage, together with nine DC shocks and intra venous bicarbonate injections the rhythm reverted to a nodal tachycardia, initial 2D echocardiogram showed left ventricular dysfunction, which recovered to normal after 2 weeks and the patient had a complete recovery subsequently. CONCLUSION: Our case highlights the importance of continued resuscitation in patients presenting with TCA poisoning and resistant arrhythmia, especially in young and otherwise healthy patients.
