Patients were treated with protriptyline or nortriptyline (double-blind). They were assessed on the Zung Depression Scale and on the Hostility and Direction of Hostility Questionnaire (HDHQ). A good response was heralded by low ratings on criticism of self and others,and on projected (paranoid) hostility. The outcome was better with initial low scores on depressive symptoms, particularly unworthiness, restlessness and constipation. As to reported side effects, initial loss of interest augured badly for drowsiness, lack of clear mind for blurred vision, loss of libido for constipation and ideas of suicide for dry mouth.

Nonsalicylate, nonsteroidal anti-inflammatory drugs (NSAIDs) can be divided into 4 chemical classes: acetic acids, fenamic acids, oxicams and propionic acids. Most NSAID overdoses result in a benign outcome. Of 50,614 exposures reported to poison centres in the United States in a 2-year period, 131 (0.26%) had a major outcome, with 10 deaths. Despite the generally mild effects reported in large patient series, isolated case reports have documented serious toxicity, such as seizures, hypotension, apnoea, coma and renal failure. The majority of these consequences occur after ingestion of substantial quantities by adults attempting suicide. Rarely, with ibuprofen and piroxicam, children who ingest small amounts in accidental exposure develop serious toxicity. Typical signs and symptoms of NSAID overdose include nausea, vomiting, headache, drowsiness, blurred vision and dizziness. Seizures are rarely documented across all NSAID classes, with the exception of mefenamic acid (where seizures occur in over one-third of cases), or following massive ingestion of other agents. Drugs in the propionic acid group have produced metabolic acidosis, respiratory depression and coma in severe cases. Ibuprofen is the agent with the most published data on overdose, probably because it is available without a prescription in many countries. Symptoms are unlikely after ingestion of 100 mg/kg or less, and are usually not life-threatening unless more than 400 mg/kg is ingested. There is some relationship between plasma concentrations and the potential for development of symptoms, but plasma concentrations have no impact on treatment decisions. Treatment of NSAID overdose is entirely supportive. Recent trends in emergency department procedures regarding gastric decontamination are evolving towards the recommended administration of activated charcoal without gastric emptying in patients presenting more than 1 hour after ingestion, although gastric lavage, followed by administration of activated charcoal, may be advisable in patients who present earlier. Home administration of syrup of ipecac is still recommended if treatment is given shortly after ingestion, with a few exceptions: for example, ipecac is contraindicated after ingestion of mefenamic acid or ibuprofen in amounts greater than 400 mg/kg. Urine alkalinisation and diuresis have been recommended to enhance the elimination of NSAIDs, based on a pKa in the range of 3 to 5. However, because the drugs are universally highly protein bound, with little unchanged renal excretion, this technique is not likely to be beneficial. Haemodialysis is also unlikely to enhance elimination, but may be required if oliguric renal failure develops. Multiple dose activated charcoal may be useful in enhancing elimination of NSAIDs with long half-lives, such as piroxicam and sulindac.

To study acute organophosphorus (OP) poisoning cases, 190 OP-intoxicated cases admitted to Civil Hospital, Ahmedabad, were investigated in depth. The group consisted of subjects ranging from 11 to 60 years of age, with the maximum number of cases in the age group 21-30 years and a male-to-female ratio of 2.1:1. Most of the subjects (71.61%) were partially educated, 24.2% of the cases were illiterate, and only 4.2% of the cases were highly educated. Socioeconomically, 21.1% of the subjects were of low economic status, 52.6% were low middle class, 16.8% were upper middle class, and only 9.5% were upper class. With regard to marital status of the subjects, 98 cases were married and 92 were unmarried. About 67.4% of the cases had the intention of committing suicide, 16.8% of the cases were the result of occupational exposure, and 15.8% of the cases were from accidental poisoning. Social and domestic problems (37.5%), marital friction (15.6%), financial stress (15.6%), love affairs (14.1%), job problems (10.9%), chronic illness (4.7%), and failure in examination (1.6%) were observed as the precipitating factors. Muscarinic manifestations such as vomiting (96.8%), nausea (82.1%), miosis (64.2%), excessive salivation (61.1%), and blurred vision (54.7%) and CNS manifestations such as giddiness (93.7%), headache (84.2%), disturbances of consciousness (44.2%), and typical pungent odor from mouth and clothes (77.9%) were the main presenting symptoms. Cardiac manifestations such as sinus tachycardia (25.3%), sinus bradycardia (6.3%), and depression of ST segments with T-wave inversion (6.3%) were observed electrocardiographically, with hypertension (10.5%) and muscular twitching in some (2.1%) cases. Biochemical changes such as albuminuria (12.6%) and azotemia (18.9%) with inhibition of acetylcholinesterase enzyme activity in blood were recorded in 78.9% of the cases. About 89.5% of the cases recovered completely, 4.2% of the cases absconded after partial recovery, and 6.3% of the cases died. The mortality rate (6.3%) depended on various factors such as the organophosphorus compound consumed, the amount ingested, the time interval for hospitalization, and the general health of the patient. Chances of recovery were higher when the patient was hospitalized at the earliest indication.

Sertraline is a serotonin reuptake inhibitor that has been approved for use in the treatment of depression. Its side-effect profile is similar to that of fluoxetine, a drug of the same class. The side effects of these drugs most often affect the gastrointestinal tract. Serotonin reuptake inhibitors are nonsedating and free of cardiac effects; they do not cause hypotension, urinary retention or blurred vision. Sertraline, like fluoxetine, appears to be safer than tricyclic antidepressants in overdose. However, no clinical studies comparing sertraline and fluoxetine have been published. The wholesale cost of a month's supply of sertraline is about $50, compared with about $5 for a generic tricyclic antidepressant. Despite their cost, serotonin uptake inhibitors may be the initial drugs of choice in depressed elderly patients, because these patients are at increased risk for suicide and have a low tolerance for the side effects of tricyclic antidepressants.

Orbital subperiosteal hematomas are rare and most often result from facial trauma; however, occurrence of these hematomas due to non-traumatic causes is extremely rare. Herein, we present the case of a 38-year-old man who was transferred to our emergency department because he became comatose after attempting suicide by hanging. He underwent computed tomography (CT) of the head and neck. CT findings revealed a bilateral orbital subperiosteal hematoma. We then performed magnetic resonance imaging (MRI) of the head for definite diagnosis of hematoma. There is no consensus regarding if this condition should be treated conservatively or surgically. Conservative management was selected for this patient because he was in deep coma. Some non-traumatic causes of orbital subperiosteal hematoma include weight lifting, coughing, vomiting, Valsalva maneuver, labor, and scuba diving. Sudden elevations in cranial pressure may be the mechanism underlying this condition. Although suicide attempt by hanging could have caused a sudden elevation in cranial pressure, this is the first report of the occurrence of this condition. Patients with orbital subperiosteal hematomas generally complain of blurred vision, eye pain, or exophthalmos. However, identifying this sign may be difficult in patients with disturbed consciousness.
