An unusual presentation of hemiparesis with complex ophthalmoplegia: A 'nine' syndrome.

Nine syndrome is a rare clinical entity with core clinical signs of one and a half syndrome, ipsilateral facial palsy, and contralateral hemiparesis/hemianesthesia and localizing to the dorsal paramedian pontine tegmentum. The awareness of this sign helps in precise localization and consideration of relevant aetiologies. Here, we report a case consisting of right horizontal gaze palsy with right internuclear opthalmoplegia and right lower motor neuron type VII nerve palsy constituting eight-and-a-half syndrome. With the additional involvement of left upper and lower limb upper motor neuron weakness, it revealed the lesion responsible for the 'nine' syndrome in magnetic resonance imaging of the brain. It is our purpose to highlight the genesis of this combination of clinical signs.

Descriptive cross-sectional study on knowledge, awareness and adherence to medication among hypertensive patients in a tertiary care center, Eastern Sri Lanka.

INTRODUCTION: Hypertension is one of the common non-communicable diseases and public health problem among developed and developing countries. The lack of knowledge and awareness on hypertension and poor adherence of medication are a major challenge to control hypertension and prevent its complications. Our study aimed to assess the knowledge, awareness of hypertension and adherence to medication among hypertensive patients attending the medical clinics of a tertiary care center, Eastern Province of Sri Lanka. METHODS: A descriptive cross-sectional study was conducted among hypertensive patients to assess knowledge, awareness of hypertension and adherence to medication in medical clinics in a tertiary care for 6 months duration. Data were collected by using pretested and validated Hypertension Facts Questionnaire. Their medication adherence and the reasons for nonadherence were studied using Medication Adherence Scale. Data were analyzed using SPSS (version 18) analytical package and the chi-square test was performed. The scoring system was used to categorize the level of knowledge and awareness of hypertension among patients. RESULTS: The majority of patients had moderate-to-high knowledge (101, 65.8%) about hypertension and had moderate-to-high awareness (111, 73.2%) on hypertension. Even though, 134 (87.6%) patients knew that they have hypertension, and 108 (70.6%) patients did not know their blood pressure value at the time of diagnosis. Most of the patients (90, 58.8%) had good drug adherence, and most of them (141, 92.1%) thought that taking medicine plays a key role to control their blood pressure. The main reasons for nonadherence of medication were forgetfulness (39, 32%) and expenses (46, 35.4%). The knowledge and awareness about hypertension among respondents were significantly associated with educational level (p < 0.05). CONCLUSION: Most of the patients had adequate knowledge on the risk factors and complications of hypertension. But they were unaware about their disease status, and their diagnosis, target organ damage and recent blood pressure values. The drug adherence was reasonably adequate. The main reasons for nonadherence of medication were forgetfulness and expenses.

Thrombotic microangiopathy following saw-scaled viper (Echis carinatus) envenoming in Sri Lanka.

The saw-scaled viper (Echis carinatus) is considered as a highly venomous snake in Sri Lanka. The clinical manifestations are localized pain and swelling, coagulopathy and renal impairment. Thrombotic microangiopathy is rarely reported as a complication of saw-scaled viper envenoming. The clinical manifestations of thrombotic microangiopathy include thrombocytopenia, microangiopathic haemolytic anaemia and acute kidney injury. The consumption coagulopathy of post-envenoming could be followed by a syndrome consistent with thrombotic microangiopathy. We describe a patient with thrombotic microangiopathy following saw-scaled viper systemic envenoming which was managed with antivenom and supportive therapy. The dead snake which was brought by patient was identified by medical professional as saw-scaled viper (E. carinatus) based on morphological features. This case illustrates a rare manifestation thrombotic microangiopathy following saw-scaled viper envenoming.

Kounis syndrome: Acute myocardial infarction following multiple bee stings.

Usually, bee sting systemic envenomation is self-limited mild allergic reaction rarely associated with systemic manifestations such as anaphylaxis, myocardial injury, encephalitis, acute kidney injury and serum sickness. Kounis syndrome also known as allergic myocardial infarction is uncommon clinical feature and reported cases are scarce in literature. Herein, we described a hypothetical case of Kounis syndrome diagnosed in a 74-year-old man initially presenting for anaphylactic reaction.

Acute poisoning with acetamiprid, a type of neonicotinoid insecticide causing severe lactic acidosis: A case report.

Acetamiprid is a type of neonicotinoid that belongs to the new class of insecticides. It is fatally toxic to insects by acting as an agonist to nicotinic acetylcholine receptors. Cases with neonicotinoids including acetamiprid poisoning in humans were reported around the world. Only one case with acetamiprid poisoning associated with severe adverse effects has been described from Sri Lanka. Serious side effects will occur if it is consumed in excess amount. Here, we described a case of acetamiprid poisoning in a man who developed severe lactic acidosis, myocardial suppression, hyperglycemia, and intestinal obstruction following accidental intake of acetamiprid insecticide. The patient was managed conservatively as there is no specific management mentioned in the literature.

Saw-scaled viper envenoming complicated with acute myocardial infarction.

The saw-scaled viper (Echis carinatus) is considered to be a venomous snake which is especially seen in Northern Sri Lanka. Systemic manifestations are rare and reported complications include coagulopathy and renal impairment. The cardiac toxicity following snakebites is rare and cardiac involvement following the saw-scaled viper bites is extremely rare. Here, we describe a patient with acute myocardial infarction following systemic envenoming by saw-scaled viper in Northern Sri Lanka, which was successfully managed per ward protocol following national guidelines.

Acute liver injury associated with Oxyfluorfen toxicity.

Oxyfluorfen is a phenoxyphenyl-type herbicide which is used for broad-spectrum control of broadleaf and grassy weeds. Ingestion of toxic dose of oxyfluorfen can be fatal among animals. However, toxicity to humans are rare in literature. The alterations in haem biosynthesis (anaemia) and in liver are the primary toxic effects. There are no specific antidotes and none of the current treatments have proven efficacious till date. Therefore, prevention needs to be the utmost priority, and on exposure, aggressive decontamination should be initiated. Herein, we described an oxyfluorfen toxicity with acute hepatic injury in a young woman who presented with a deliberate self-harming with an oxyfluorfen poisoning in Sri Lanka.

Acute poisoning with acetamiprid: a case report.

BACKGROUND: Acetamiprid is a potent new first-generation neonicotinoid insecticide in agricultural practices. It is well described that it has low toxicity among animals and is lethal if consumed in large amounts. However, toxicity in humans is rarely reported in literature. Here, we describe acetamiprid toxicity complicated with severe lactic acidosis, myocardial ischemia, refractory hypotension, and severe hypokalemia in a middle-aged man who presented with deliberate self-harming with acetamiprid poisoning in Sri Lanka. CASE PRESENTATION: We describe a case of acute poisoning with an acetamiprid in a middle-aged Sri Lankan Tamil farmer for suicidal purposes following family conflicts with his wife. He presented with severe nausea, vomiting, and altered level of consciousness. He had electrocardiogram changes, hypoxia, and lactic acidosis. With intensive care management including ventilatory support, inotropic therapy along with intraarterial blood pressure monitoring, correction of acidosis, and administration of electrolytes, he made good clinical recovery. He was discharged without any further complications 6 days after ingestion of acetamiprid. CONCLUSIONS: This case illustrates a rare, acute poisoning with acetamiprid in human, as well as its clinical manifestations and successful management with supportive therapy. This will be helpful for clinicians to identify clinical manifestations and to guide management of acute poisoning with acetamiprid in the future.

Thrombotic microangiopathy following hump-nosed viper 'Hypnale' envenomation.

The hump-nosed vipers which compromise 'Hypnale hypnale', 'H. zara' and 'H. nepa' have been highly venomous snakes and 'H. zara' and 'H. nepa' are indigenous to Sri Lanka and 'H. hypnale' is endemic to Sri Lanka and India. The clinical presentations range from local swelling, blistering and necrosis at the site of bite with distinct fang marks to systemic envenomations such as coagulopathy, thrombotic microangiopathy, acute kidney injury and death in severe cases. Here, we report a case of thrombotic microangiopathy following hump-nosed viper 'Hypnale' bite.

Yellow oleander poisoning in eastern province: an analysis of admission and outcome.

INTRODUCTION: Cardiac toxicity after self-poisoning from ingestion of yellow oleander seeds is common in Eastern Sri Lanka. OBJECTIVE: To determine the clinical manifestations, cardiac arrhythmias, electrolytes abnormalities and outcome of management using currently available treatment, Poisoning Unit, Tertiary Care Hospital in Eastern Sri Lanka. MATERIALS AND METHODS: We studied 65 patients [Mean age : 23(± 0.43)yrs], (Male: Female=27:38) with yellow oleander poisoning (YOP) admitted to a Poisoning Unit, Tertiary Care Hospital in Eastern Sri Lanka from January to December 2011. RESULTS: Most patients are symptomatic who presented with classical symptoms of vomiting, abdominal pain and diarrhea. Cardiac dysrhythmias such as bradycardia or an irregular pulse are the most common findings on examination. Most symptomatic patients had conduction defects affecting the sinus node, the atrioventricular (AV) node, or both. Patients showing cardiac arrhythmias that required transfer for specialised management had significantly higher serum potassium concentrations. Almost all patients were treated with multiple activated charcoal even late presentation. Patients with brad arrhythmias were treated with intravenous boluses of atropine and intravenous infusions of isoprenaline. Temporary cardiac pacing was done for those not responding to drug therapy. There were two deaths (3.07%), both had third-degree heart block. They died even definitive treatment could be instituted. Of the remaining 63 patients, 54 (83.1%) patients required treatment, and 29 were treated with only atropine and/or isoprenaline while one required cardiac pacing in addition. 12 (18.4%) patients had arrhythmias that were considered life threatening (second-degree heart block type II, third-degree heart block and nodal bradycardia). They had good recovery even though they had developed cardiac toxicity. CONCLUSIONS: YOP are common among young females. The cardiac toxicity develops within 24 hrs of ingestion of YO seeds. The risk of toxicity has negative correlation with number of seeds. Most patients have nonspecific symptoms. AV conduction defects are common. Multiple activated charcoals alone were safe and adequate in most cases even late presentation.
