Bartter syndrome-like phenotype in a patient with diabetes: a case report

Abstract Background Bartter’s syndrome is a rare genetic tubulopathy affecting the loop of Henle leading to salt wasting. It is commonly seen in utero or in early neonatal period. Rare cases of acquired Bartter’s syndrome are reported in association with infections like tuberculosis, granulomatous conditions like sarcoidosis, autoimmune diseases, and drugs. The mainstay of management includes potassium, calcium, and magnesium supplementation. Case presentation We report the case of a 62-year-old Sri Lankan Sinhalese man with diabetes and hypertension presenting with generalized weakness with clinical evidence of proximal myopathy. He was severely hypokalemic with high urinary potassium excretion and hypochloremic metabolic alkalosis. He poorly responded to intravenously administered potassium supplements. A diagnosis of idiopathic Bartter-like phenotype was made. He responded well to spironolactone and indomethacin. Conclusions Patients presenting with body weakness need serum potassium estimation. Acquired Bartter’s syndrome although rare, should be ruled out in those with hypokalemia and metabolic alkalosis with increased urinary potassium loss with poor response to potassium replacement

The effectiveness of radial extracorporeal shock wave therapy vs transcutaneous electrical nerve stimulation in the management of upper limb spasticity in chronic-post stroke hemiplegia-A randomized controlled trial.

BackgroundTraditionally both rESWT and TENS are used in treating post-stroke upper limb spasticity over years and their effectiveness had been assessed disjointedly. However, these methods were not yet compared for superiority.ObjectivesTo compare rESWT vs TENS to assess their effectiveness in different parameters of stroke such as stroke type, gender, and the affected side.MethodsThe experimental group was treated with rESWT application to the middle of the muscle belly of Teres major, Brachialis, Flexor carpi ulnaris, and Flexor digitorum profundus muscles using 1500 shots per muscle, frequency of 5Hz, energy of 0.030 mJ/mm. The TENS was applied to the same muscles in the control group using 100 Hz for 15 minutes. Assessments were taken at the baseline (T0), immediately after first application (T1), and at the end of four-week protocol (T2).ResultsPatients 106 with a mean age of 63.87±7.052 years were equally divided into rESWT (53) and TENS (53) groups including 62 males, 44 females, 74 ischemic, 32 hemorrhagic, affecting 68 right, and 38 left. Statistical analysis has revealed significant differences at T1 and T2 in both groups. But at T2 compared to T0; the rESWT group has reduced spasticity 4.8 times (95% CI 1.956 to 2.195) while TENS reduced by 2.6 times (95% CI 1.351 to 1.668), improved voluntary control by 3.9 times (95% CI 2.314 to 2.667) and it was 3.2 times (95% CI 1.829 to 2.171) in TENS group. Improvement of the hand functions of the rESWT group was 3.8 times in FMA-UL (95% CI 19.549 to 22.602) and 5.5 times in ARAT (95% CI 22.453 to 24.792) while thrice (95% CI 14.587 to 17.488) and 4.1 times (95% CI 16.019 to 18.283) in TENS group respectively.ConclusionThe rESWT modality is superior compared to the TENS modality for treating chronic post-stroke spastic upper limb

A case of delayed neurological manifestation following carbon monoxide poisoning in Sri Lanka: epidemiology of exposure and literature review

Abstract Background Carbon monoxide poisoning is a common emergency worldwide, which carries high morbidity and mortality. Some patients who recover from the insult of acute carbon monoxide toxicity may later develop delayed neuropsychiatric sequelae (DNS) after a lucid period in the form of cognitive impairments, a broad spectrum of neurological deficits and affective disorders. Here, we present the first case of DNS following carbon monoxide poisoning in Sri Lanka and epidemiology of the exposure of nine (9) more victims. Case presentation A 55-year-old patient and nine other people developed effects of carbon monoxide poisoning in two different occasions after sleeping few hours in the same room in their work place in Sri Lanka. These patients developed spectrum of symptoms with the acute carbon monoxide poisoning. However, one patient developed neurological deterioration pertaining to delayed neuropsychiatric sequelae (DNS) after 1 month of lucid interval. His MRI scan of the brain showed diffuse high signal intensity involving subcortical white matter, globus pallidus on FLAIR and T2W images. These areas showed high signals in DWI images with no significant changes appreciated on ADC map. There was no abnormal contrast enhancement appreciated in the above areas. EEG showed generalized slow waves. He gradually deteriorated over next 2 weeks, exhibited athetoid movements of his feet and hands and went into rigid akinetic mute state. He could not response to any stimulation and even displayed decorticated-like posture and died. Others had normal MRI brain finding at 8 weeks of acute toxicity and all were neurologically normal after 1 year. Conclusion Though, it is uncommon in a tropical country like Sri Lanka, clinicians should have high degree of suspicion with the correct circumstances, as it is a challenge for the emergency physicians, even in countries with higher rate of CO poisoning. The exact mechanisms of acute and delayed toxicity, preventive methods and the suggested treatments are yet to be elucidated and this needs further attention and studies

Blood transfusion in severe dengue infection: a case series

Abstract Background Dengue is still a recurrent challenge to the global population, without specific antiviral therapy. Clinical management strategies are aimed to mitigate the deaths. The use of blood products in dengue is recommended mainly in cases of bleeding. Case presentation We prospectively collected data on Sri Lankan dengue cases in the Teaching Hospital, Peradeniya, Sri Lanka from 2017, and selected ten severe cases where blood transfusions were involved in the management. The series comprises seven females and three males, with a median age of 36 years (range 12–53 years). All patients were critically ill at the time of blood transfusion, with dramatic stabilization of vital parameters after the transfusions. Only one patient had detectable bleeding, while five patients had occult blood loss as indicated by dropping hematocrit. Even though four patients had stable hematocrit, they had metabolic acidosis. Two patients had a very high increase of hepatic transaminases along with acidosis. Two patients had myocarditis with dropping hematocrit, suggestive of occult bleeding. Conclusions Clinical deterioration despite fluid management commonly occurs due to occult bleeding in dengue infection. Blood transfusion is lifesaving in such cases of blood loss, acidosis, and severe hepatic damage. The mechanism of this effect needs an explanation, such as enhanced oxygen delivery to the tissues and hemostasis to hypothesize a few possibilities
