Accidental or intentional ingestion of carbofuran can produce a life-threatening syndrome that requires prompt diagnosis and treatment. This paper investigates unintentional carbofuran poisoning in farm workers. Thirteen patients were admitted to the emergency department with carbofuran poisoning between January 2002 and August 2004 (2 female, 11 male). The patients had been poisoned while mixing the liquid form of carbofuran with seeds. Their hands were red on admission. Complaints most commonly reported by the patients on admission were nausea, vomiting, headache, weakness, dizziness and blurred vision. The most commonly observed signs were tachycardia, tachypnea, salivation, miosis, elevated blood pressure, and fasciculation. Three patients were agitated and one was lethargic on admission. We reviewed the patients' medical charts retrospectively, as well as the demographic data, intoxication route, clinical and laboratory presentations, and outcomes. We made the diagnosis according to a compatible exposure history and clinical findings. The most commonly observed laboratory finding was hyperglycemia, which was found in 6 patients. Serum pseudocholinesterase level was low in only one patient. All the patients were cured and discharged from the hospital in good physical condition. Rapid onset, mild illness and quick recovery are typical characteristics of acute occupational carbofuran poisoning. We conclude that public health efforts should educate farm workers about the dangers of pesticide application so that its threat can be diminished.

We report two cases of spotted black snake (Pseudechis guttatus) envenoming. One patient experienced localised burning pain around the bite and developed nausea, vomiting, diarrhoea, upper abdominal cramping and diaphoresis. He was treated with intravenous fluids and antiemetics, but no antivenom, and was discharged 23 hours after the bite. The second patient developed a severe headache, blurred vision and mild nausea, associated with severe pain and swelling of the bitten limb that took 4 days to resolve. No antivenom was given and the patient had no sequelae. Neither patient developed significant coagulopathy, myolysis or neuromuscular paralysis. Bites by this species appear to cause effects similar to those of the more common red-bellied black snake (P. porphyriacus).

A rare case of neurosarcoidosis presenting as an isolated quadrigeminal plate mass without systemic manifestation of this disease is reported. This 26-year-old man presented with symptoms of acute intracranial hypertension including headache, morning vomiting as well as a right homonymous hemianopsia. Magnetic resonance imaging (MRI) showed an expansive tectal mass causing hydrocephalus secondary to an aqueductal obstruction. An external ventricular drainage was inserted and the mass, postulated to be a glioma, was removed through an occipital transtentorial craniotomy. Histopathological examination revealed numerous sarcoid granulomas. Postoperative course was relevant for bilateral hypoacusis and tinnitus, blurred vision, bilateral palpebral ptosis and bilateral internuclear ophthalmoplegia. Chest X-ray was normal. Postoperative thoracic computed tomography (CT) scan showed mediastinal adenopathies. Lung function tests were normal. Angiotensin converting enzyme (ACE) cerebrospinal fluid (CSF) blood ratio was normal. Postoperative treatment and follow-up included corticosteroids, serial lung function tests and cerebral MRI. Neurosarcoidosis may present with protean clinical manifestations and unusual radiological features. This rare diagnosis has to be kept in mind when facing isolated intracerebral mass lesions.

Headache makes one of the most common side effects of frequently pesticide application. This is to be taken care of in rural areas. Headaches have been reported with the use of ivermectin, ivermectin-diethylcarbamazine, organophosphates, and also with the fungicide maneb and copper sulfate, carbofuran, hexonal, dioxin, methomyl and its salts, as well as rare cases of poisoning with the fungicide combination of propineb and cymoxanil. Headache often occurs after long term work with pesticides and/or in laboratories. There are numerous symptoms accompanying headache in pesticide poisoning the most common being elevated body temperature, lassitude, dizziness, irritability, nausea, vomiting, epigastric pain, diarrhea, myalgia, pains in the arms and legs, sleepiness, pains in joints, irritation of eyes/face/skin, sweating. Much less common are respiratory disturbances, tachycardia, tachypnea and other cardiac distur bances, fall of blood pressure, gastrointestinal discomforts, constipation, poor appetite, significant decrease in leukocyte count, anemia, albuminuria, azotemia, fasciculations, miosis, blurred vision, memory disturbances and other neurologic disturbances, postural tremor, signs of cerebral function damage, bradykinesia, etc.

A 23 year-old patient was referred to the endocrine outpatient clinic with the suspicion of diabetes insipidus as he complained of nycturia and polydipsia since 2-3 months. Further he presented with nausea, vomiting, loss of appetite, rapid weight loss, diffuse body pain and fatigue. No headache, blurred vision, or fever were reported. The clinical examination showed sexual infantilism (poor beard, pubic and axillary hair growth, small testis). The patient's skin was strikingly pale as well as dry and scaly. Lymph node palpation was unremarkable. Endocrine evaluation revealed diabetes insipidus as well as complete anterior pituitary insufficiency. MR imaging demonstrated contrast-enhancing mass lesions at the pineal gland, hypothalamus, and anterior horn of lateral ventricles bilaterally. The localization pattern deemed to be highly suspicious for intracranial germinoma. As beta-HCG and AFP were negative in serum and cerebrospinal fluid the diagnosis of germinoma was confirmed histologically. After radiotherapy with cranio-spinal radiation therapy with 24 Gy followed by two weeks of local tumor boost with 16 Gy, the posttherapy MRI scan indicated complete tumor removal. This case demonstrates a very rare and potentially curable tumor as the cause of panhypopituitarism in adults.

Despite being a favorite delicacy, only 200-300 of the 5,000 known mushroom species have been clearly established to be safe for consumption. Cases of mushroom poisoning have been reported with diverse clinical syndromes. A syndromic classification of mushroom poisoning has recently been developed to facilitate early interventions. We present a series of five cases of mushroom poisoning with muscarinic manifestations to highlight the difficulties we faced with exact species and toxin identification and the importance of this syndromic classification. The common symptoms in our case series are blurred vision, diarrhea, vomiting, and abdominal cramps.

Snakebite is an environmental hazard associated with significant morbidity and mortality. We report a case series of venomous snakebites in a military operational area of north India. Of 33 cases of snake bites presenting to the military hospital, 21 patients were envenomated. The median age of patients was 24 years; all were men. All of the envenomations were neurotoxic in nature. Abdominal pain (91%), headache (86%), dysphagia (86%), ptosis (77%), diplopia (72%), blurred vision (72%), dyspnea (67%), and vomiting (62%) were the predominant clinical presentation. Polyvalent AntiSnakeVenom (ASV) [mean 180 ml; range 90-320 ml] was given to all patients with systemic manifestations, and repeated as needed. Eleven (52%) patients received neostigmine with glycopyrrolate to counter cholinergic effects. Two patients were given ventilatory support. The average time of recovery from envenomation was 16 hours after administration of ASV. All patients recovered without sequelae. Soldiers during military exercise are vulnerable to snakebites. Neurotoxic snakebites predominate in our study and usually present with autonomic features along with headache, abdominal pain, ptosis, diplopia and dysphasia. Preventive measures to minimize snake bites and planned treatment regimens should be emphasized among medical and military personnel deployed in the field operations.

We report a case of a 76-year-old woman admitted to our institution with sudden onset of dizziness and vertigo followed by vomiting and blurred vision. Her medical history was remarkable for hypertension, diabetes, and ischemic stroke in the territory of the left cerebral median artery. Her symptoms were suggestive of a cerebellar stroke. Computed tomography brain scan and neck vessel ultrasounds produced normal findings. A 24-hour blood pressure monitoring showed a reverse dipping pattern. Magnetic resonance imaging examination was performed, showing a hyperintense ischemic focus involving pons and left middle cerebellar peduncle, on T2-weighted images. On Time-of-flight (TOF)-3-dimensional magnetic resonance angiography, there was a marked reduction of basilar artery signal. The digital subtraction angiography showed a vertebrobasilar system anomaly. The right vertebral artery was hypoplastic with few thin terminal spinal branches. The left vertebral artery was vicarious to the right one in intracranial tract. V3 to V4 tract showed multiple atherosclerotic wall irregularities. The basilar common trunk was absent. An abnormal posterior inferior cerebellar artery replaced the anterior inferior cerebellar artery and superior cerebellar artery. Right posterior inferior cerebellar artery, anterior inferior cerebellar artery, and superior cerebellar artery arose from ipsilateral V4 tract. This case is the first description of pure basilar agenesia. The symptoms might be related to temporary decrement of the flow in the left vertebral artery. Furthermore, the reverse dipping pattern together with the aging, hypertension, and diabetes had probably contributed to a hemodynamic malfunction of the cerebral vascular system.

Antepartum pituitary necrosis is a rare medical condition that has only been reported in pregnant women with type I diabetes attributable to diabetes-related vasculopathy and hypercoagulability. We present for the first time a case of antepartum pituitary necrosis occurring in an uncontrolled gestational diabetes mellitus (GDM) patient. The patient was a 32-yr-old woman at 33 weeks and 2 days of gestation. She suffered from severe headache, blurred vision, dizziness, and vomiting. Her baby was delivered by Cesarean section. The brain magnetic resonance images revealed pituitary necrosis. This suggests that pituitary gland necrosis may also complicate GDM pregnancy when glucose levels are uncontrolled.

Lhermitte-Duclos disease (LDD) is a pathologic entity with progrediating, diffuse hypertrophy chiefly of the stratum granulosum of the cerebellum. Typically LDD is a unilateral lesion of the cerebellum or in vermis. Here we report a case of LDD with bilateral lesions of cerebellar hemispheres managed surgically. A 28-year-old woman presented with one-year history of progressive headache, nausea, vomiting, and blurred vision. Neurologic examination revealed a bilateral mild papilledema, mild dysmetria, and dysdiadochokinesia. The cerebellar lesions caused moderate mass effect in posterior fossa with hydrocephalus, and Chiari type I malformation. We performed the suboccipital-retrosigmoid approach, and removed completely the left intracerebellar mass. Symptoms related to elevated intracranial pressure disappeared in a short period postoperatively.
