ABSTRACT
Acute cutaneous necrosis is a rare presentation of polyarteritis nodosa (PAN). In this study, we report a presentation with symmetrical cutaneous necrosis of the lower limbs, which ascended upward at a rapid rate. A 47-year-old man presented with a fever of one day and pain in the feet for six days. He had no history of claudication. Upon examination, he was febrile, and subtle bluish discoloration was observed on the sole of his foot. There was a bilateral stocking-type paresthesia up to the ankle joint. His blood pressure on admission was 210/120 mmHg. Eight hours later, the pain subsided, but a left-sided foot drop was noted along with the paresthesia extending up both feet to approximately 10 cm above the medial malleolus. The feet turned black, and dark discoloration spread rapidly upward over the next 16 hours, and the skin became necrosed. A clinical diagnosis of vasculitis was established, and the patient received IV methylprednisolone at a daily dosage of 1 g for three days, effectively stopping the advancement of necrosis. This was followed by treatment with IV cyclophosphamide. A conclusive diagnosis of PAN was made, and the patient underwent wound debridement. After three months of physiotherapy, a successful skin graft was performed. Prompt identification of the underlying etiology is crucial to prevent the advancement of necrosis and save the limbs. When vasculitis is suspected, ruling out infectious causes is essential before starting early immunosuppressive treatment.
ABSTRACT
Longitudinally extensive transverse myelitis (LETM) is a rapidly progressing demyelinating disease affecting the spinal cord over three or more vertebral segments. Most causes are idiopathic, while others include infections, autoimmune causes, central nervous system demyelinating diseases, and post vaccination. Here, we report a 37-year-old male who presented with a fever for six days with no source of infection and complained of pain and weakness in the bilateral lower limbs eight hours after admission. Though the neurological examination of the lower limbs was normal at that time, reduced power was detected 16 hours later, with loss of proprioception and sensation of pain with a sensory level at T4 vertebrae. Then, the patient became unable to vocalize, and the chest X-ray showed an elevated left hemidiaphragm. Thirty hours after admission, the patient went into type 2 respiratory arrest and was intubated. The magnetic resonance imaging (MRI) showed a longitudinally extensive transverse myelitis extending from the C2 vertebrae to the conus medullaris. Febrile illness is common in the medical setting in Sri Lanka, but its association with LETM is unusual. Since LETM is very rare and is a rapidly progressive disease, a high degree of clinical suspicion is crucial for early diagnosis and the initiation of treatment. This case underscores the importance of early diagnosis, which would require timely MRI, and prompt treatment with intravenous (IV) glucocorticoids or plasma exchange to reduce morbidity and mortality.
ABSTRACT
Diabetic striatopathy is a rare neurological complication of diabetes mellitus that presents with sudden onset hemichorea or hemiballismus and is associated with hyperglycemia and striatal abnormality, either by hyperdensity on non-contrast computer tomography or hyperintensity on T1-weighted magnetic resonance imaging. Here we report a 55-year-old female, from Sri Lanka, who presented with involuntary movements of the left upper and lower limbs. Her past medical history included diabetes mellitus and she was on warfarin 5 mg daily for a mechanical mitral and tricuspid valve replacement. The random blood sugar on admission was 462 mg/dL and the last INR was 3.03. While hemiballismus has multiple etiologies, intracranial hemorrhage would be the main differential in a patient on anticoagulation. Other differentials include drug-induced dyskinesia, metabolic abnormalities, and autoimmune etiologies. Hemiballismus in the presence of high blood glucose should always raise the suspicion of diabetic striatopathy. The non-contrast computed tomography of the brain showed hyperdensity in the right-side caudate nucleus, lentiform nucleus, and globus pallidus which is a characteristic of diabetic striatopathy but could have been mistaken for an intracranial hemorrhage. The involuntary movements improved with glucose control and treatment with clonazepam and tetrabenazine. This case highlights the potential for misdiagnosis of diabetic striatopathy as an intracranial hemorrhage in a patient on warfarin, which can lead to delays in appropriate management and erroneous omission of warfarin. Early recognition and treatment of diabetic striatopathy can lead to significant improvement in the quality of life.
ABSTRACT
Objective: Palliative care is an intervention that improves the quality of life of patients. Nurses have a primary role in providing palliative care. Their knowledge and attitudes toward palliative care is important in care delivery. There is minimal information in Sri Lanka to document the knowledge and attitude of palliative care among nurses. Therefore, the present study was conducted to assess the knowledge and attitude of palliative care among nurses in Sri Lanka. Method: A cross-sectional, descriptive study was conducted on 200 selected nurses at Colombo North Teaching Hospital, Sri Lanka fulfilling the inclusion criteria. Socio-demographic information of the study participants was obtained through a self-administered questionnaire. The awareness and attitude levels toward the PC were assessed using the Palliative Care Knowledge Test (PCKT) and Frommelt Attitude Toward Care of the Dying, respectively. Results: More than half of the participants (55%) had an inadequate knowledge level regarding the palliative care (<50% for the PCKT score). Regarding the attitude on the palliative care, the majority stated nursing care to a dying person is a worthwhile experience (92%; n = 184). Many of them disagreed with avoiding the care of dying patients (strongly disagree: 37%; n = 74, disagree: 52.5%; n = 105). Overall, 85.5% of study participants had a positive attitude towards the palliative care. According to binary logistic regression, gender (P = .04; OR = 3.57; CI = 1.03-12.41) and working setup (P < .001) were significantly associated with having a positive attitude. The knowledge level was higher among nurses working in surgical wards (OR = 7.84). Those with >10 years of experience were statistically significant to have a positive attitude (P = .02; OR = 1.35; CI = 1.13-5.50). Conclusion: The nurses had inadequate knowledge of the PC even though they had a positive attitude toward it. Therefore, it is essential to uplift the awareness level among health workers. This warrants the need for palliative care education in the nursing curriculum and continuous professional development.

Importance: Poorly controlled hypertension is a leading global public health problem requiring new treatment strategies. Objective: To assess whether a low-dose triple combination antihypertensive medication would achieve better blood pressure (BP) control vs usual care. Design, Setting, and Participants: Randomized, open-label trial of a low-dose triple BP therapy vs usual care for adults with hypertension (systolic BP >140 mm Hg and/or diastolic BP >90 mm Hg; or in patients with diabetes or chronic kidney disease: >130 mm Hg and/or >80 mm Hg) requiring initiation (untreated patients) or escalation (patients receiving monotherapy) of antihypertensive therapy. Patients were enrolled from 11 urban hospital clinics in Sri Lanka from February 2016 to May 2017; follow-up ended in October 2017. Interventions: A once-daily fixed-dose triple combination pill (20 mg of telmisartan, 2.5 mg of amlodipine, and 12.5 mg of chlorthalidone) therapy (n = 349) or usual care (n = 351). Main Outcomes and Measures: The primary outcome was the proportion achieving target systolic/diastolic BP (<140/90 mm Hg or <130/80 mm Hg in patients with diabetes or chronic kidney disease) at 6 months. Secondary outcomes included mean systolic/diastolic BP difference during follow-up and withdrawal of BP medications due to an adverse event. Results: Among 700 randomized patients (mean age, 56 years; 58% women; 29% had diabetes; mean baseline systolic/diastolic BP, 154/90 mm Hg), 675 (96%) completed the trial. The triple combination pill increased the proportion achieving target BP vs usual care at 6 months (70% vs 55%, respectively; risk difference, 12.7% [95% CI, 3.2% to 22.0%]; P < .001). Mean systolic/diastolic BP at 6 months was 125/76 mm Hg for the triple combination pill vs 134/81 mm Hg for usual care (adjusted difference in postrandomization BP over the entire follow-up: systolic BP, -9.8 [95% CI, -7.9 to -11.6] mm Hg; diastolic BP, -5.0 [95% CI, -3.9 to -6.1] mm Hg; P < .001 for both comparisons). Overall, 419 adverse events were reported in 255 patients (38.1% for triple combination pill vs 34.8% for usual care) with the most common being musculoskeletal pain (6.0% and 8.0%, respectively) and dizziness, presyncope, or syncope (5.2% and 2.8%). There were no significant between-group differences in the proportion of patient withdrawal from BP-lowering therapy due to adverse events (6.6% for triple combination pill vs 6.8% for usual care). Conclusions and Relevance: Among patients with mild to moderate hypertension, treatment with a pill containing low doses of 3 antihypertensive drugs led to an increased proportion of patients achieving their target BP goal vs usual care. Use of such medication as initial therapy or to replace monotherapy may be an effective way to improve BP control.

The prevention of adverse drug reactions to antivenom serum poses a formidable challenge in the management of snakebite. Hydrocortisone is being used concurrently with antivenom in order to prevent these adverse drug reactions without a proven benefit. However, all previous studies seemed to ignore the testing of effectiveness of hydrocortisone therapy during its pharmacological effects, which come hours later. On this principle, we aimed to test the effectiveness of intravenous hydrocortisone given 2 h or more prior to the commencement of antivenom therapy to reduce adverse drug reactions to antivenom. In an open-labelled randomized controlled trial, patients with a history of snakebite were randomly assigned to receive either 500 mg intravenous hydrocortisone bolus given 2 h or more prior to antivenom therapy (Group A) or at the time of antivenom therapy (Group B). The primary endpoint was the reduction of adverse drug reactions to antivenom of any grade of severity within the first 48 h. This trial has been registered with the "Sri Lanka Clinical Trials Registry", number SLCTR/2010/005. A total of 236 patients were randomized to group A or Group B. In the group A, 38 participants received hydrocortisone 2 h before administration of antivenom whilst 33 received hydrocortisone less than 2 h before administration of antivenom. In the Group B, 84 participants received hydrocortisone at the time of antivenom therapy. In Group A (n, 38), and Group B (n, 84), 15 patients (39%) and 29 patients (35%) developed reactions respectively and the difference is not significant (p = 0.598). Moreover, hydrocortisone therapy did not significantly reduce the occurrence of antievnom reactions of any grade of severity. Further, it didn't delay the occurrence of antivenom reactions in patients who received hydrocortisone either more than 2 h or less than 2 h before the antivenom as opposed to the control group (group B). Intravenous hydrocortisone shows no difference in the timing, rate or severity of adverse drug reactions to antivenom when administered simultaneously and up to 4 h prior to antivenom.

The Russell's viper (Daboia russelii) is responsible for 30-40% of all snakebites and the most number of life-threatening bites of any snake in Sri Lanka. The clinical profile of Russell's viper bite includes local swelling, coagulopathy, renal dysfunction and neuromuscular paralysis, based on which the syndromic diagnostic tools have been developed. The currently available Indian polyvalent antivenom is not very effective in treating Russell's viper bite patients in Sri Lanka and the decision regarding antivenom therapy is primarily driven by clinical and laboratory evidence of envenoming. The non-availability of early predictors of Russell's viper systemic envenoming is responsible for considerable delay in commencing antivenom. The objective of this study is to evaluate abdominal pain as an early feature of systemic envenoming following Russell's viper bites. We evaluated the clinical profile of Russell's viper bite patients admitted to a tertiary care centre in Sri Lanka. Fifty-five patients were proven Russell's viper bite victims who produced the biting snake, while one hundred and fifty-four were suspected to have been bitten by the same snake species. Coagulopathy (159, 76.1%), renal dysfunction (39, 18.7%), neuromuscular paralysis (146, 69.9%) and local envenoming (192, 91.9%) were seen in the victims, ranging from mono-systemic involvement to various combinations. Abdominal pain was present in 79.5% of these patients, appearing 5 minutes to 4 hours after the bite. The severity of the abdominal pain, assessed using a scoring system, correlated well with the severity of the coagulopathy (p<0.001) and the neurotoxicity (p<0.001). Its diagnostic validity to predict systemic envenoming is - Sensitivity 81.6%, Specificity 82.4%, Positive predictive value 91.2%. Thus, abdominal pain is an early clinical feature of systemic Russell's viper bite envenoming in Sri Lanka. However, it is best to judge abdominal pain together with other clinical manifestations on decision making.

BACKGROUND: Although snake bite remains a major health problem in Sri Lanka, there is a dearth of baseline information that would be useful in education about and prevention of snakebite. OBJECTIVES: The purpose of this study was to describe the socio-demographic characteristics, behavioral responses, treatment seeking, and prehospital interventions of snakebite victims in an area with high snakebite burden. METHODS: This prospective study was based on a cohort of snakebite victims presented to the Anuradhapura Teaching Hospital over a 1-year period from January 2010. RESULTS: Of the total of 1018 snakebite admissions, 69% were male and 65.8% were aged 21 to 50 years. Most of the victims were farmers (40%). The offending snakes were seen by 549 victims (54%); of these, only 46% (255) presented with a dead snake specimen. Only 38 of 1018 (4%) had first sought some form of indigenous treatment such as locally applied medications, herbal decoctions, nasal insufflations ("Nasna"), or applying snake stone over the bitten site. Some form of first aid had been adopted by 681 victims (67%), of whom all had washed the bitten site, and 18 victims (2%) and 4 (0.4%) had applied a dressing or incised the bitten site, respectively. A tourniquet had been applied by 353 victims (35%) for mean duration of 26 minutes (range, 5 to 120 minutes). None of the patients had immobilized the bitten limb by splinting. Oral medications had been used for pain relief in 74 cases (7%), paracetamol by all. CONCLUSIONS: A proportion of patients still seek native remedies and use inappropriate first aid after snakebite in Sri Lanka.

Hump-nosed pit vipers of Genus Hypnale are the commonest cause of snake bite in Sri Lanka. Although there are many reports of local effects, coagulopathy and acute kidney injury, it remains unclear how frequent these clinical effects are and therefore the medical importance of this snake genus. The genus has been recently revised to include Hypnale hypnale from Sri Lanka and Western Ghats of Southern India, and the two endemic species to Sri Lanka, Hypnale zara and Hypnale nepa. This was a prospective hospital-based clinical study of definite Hypnale spp. bites from July 2008 to July 2010 in six Sri Lankan hospitals. There were 114 patients included and all snakes were correctly identified by hospital staff as Hypnale spp. Of these, 93 snakes were identified as H. hypnale by an expert, 16 as H. zara and five as H. nepa. Most bites occurred on the lower limbs in the daytime. There was no difference in the clinical effects between the three species. Pain and fang marks were present in all patients, 101 had local swelling and only 16 (14%) developed extensive local swelling that spread proximally and involved more than half of the bitten limb. Systemic symptoms occurred in 18 patients; four patients had an abnormal 20 min whole blood clotting test and one patient developed an acute kidney injury that required haemodialysis. All patients were discharged alive with a median length of stay of 2 days. This study confirms that hump-nosed viper bites cause only minor effects in most cases. Future studies need to undertake formal coagulation studies and identify important early indicators of renal impairment.

Although the strain causing cutaneous leishmaniasis (CL) in Sri Lanka was first identified in 2003, the strain causing visceral leishmaniasis (VL) has not yet been identified. We report the first isoenzyme typing of a strain causing VL in Sri Lanka at an early stage of emergence of VL in the country. The parasite was isolated from a 57-year-old civil soldier who had been in the jungle in the Vavuniya district in the Northern Province of Sri Lanka for a period of nearly 6 months immediately before the onset of symptoms. Multilocus enzyme electrophoresis (MLEE) revealed that the strain is Leishmania donovani zymodeme MON-37, the zymodeme which was previously identified from the CL patients in the country. The MLEE analysis was confirmed by sequencing the gene encoding the 6-phosphogluconate dehydrogenase isoenzyme. This is an instance of the same Leishmania zymodeme associated with both dermotropism and viscerotropism in the same geographic region. Further investigations into the genetic structure and identification of virulence factors in the parasite and immune factors in the host are required to understand the factors responsible for different tropism shown by the same zymodeme MON-37 L. donovani from Sri Lanka.

A 21 year old boy with borderline lepromatous leprosy and normal glucose-6-phosphate-dehydrogenase activity developed haemolytic anaemia, hepatitis and agranulocytosis following 19 weeks of multi-bacillary multi-drug therapy. With early administration of antibiotics and G-CSF our patient recovered without residual complications. All patients taking dapsone should be warned to discontinue the drug immediately in the event of fever, chills and sore throat occurring within the treatment period until further investigations are performed.
