An outbreak of unexplained illness occurred in members of an army reserve unit after field training in an area of New Jersey endemic for Lyme disease. Nine (12%) of the 74 who attended the exercise had serological evidence of Ehrlichia infection, defined as a single rise in titer of antibody to Ehrlichia canis greater than or equal to 1:160 four weeks after training. Two reservists with early serum samples had documented seroconversion, defined by a four-fold or greater increase in titer of antibody to E. canis, with a peak titer of greater than or equal to 1:160. Reservists with serological evidence of Ehrlichia infection were more than three times as likely to report arthralgia, myalgia, headache, appetite loss, nausea, eye pain, and abdominal pain than the other reservists. No reservist with serological evidence of Ehrlichia infection was hospitalized and most had minimal or no symptoms. This outbreak of ehrlichiosis suggests that the usual symptoms of Ehrlichia infection are milder than previously reported and that ehrlichiosis must be considered in symptomatic persons with recent tick exposure.

The authors investigated the role of secondary immunologic response, virus serotype, age, and sex on the clinical manifestations of dengue fever in Puerto Rico. From surveillance data for 1990 and 1991, this study identified 3,926 laboratory-positive cases, including 889 for whom dengue immunologic status and symptoms could be ascertained. Of those, 622 cases were virologically confirmed, and 267 cases were serologically confirmed. More than 50% of all positive patients reported fever, chills, headache, eye pain, body pains, joint pains, nausea, vomiting, or skin rash. The frequency of reporting signs, symptoms, and hospitalization was significantly higher among persons with secondary infections diagnosed by serological methods. Only rash was more common among those with primary infections. Symptom reporting increased with age; body pains, joint pains, and rash were significantly more frequently reported by female patients. No significant difference in symptom frequency was found among the virologically confirmed cases, comparing primary and secondary cases or infections due to different serotypes. The data for serologically confirmed cases suggest that in Puerto Rico the manifestations of dengue fever are, as with dengue hemorrhagic fever in Asia, more prominent among those who are experiencing secondary infections, and this effect may be more marked in the younger age groups.

Intraocular pressure elevation after the use of viscoelastic agents in uncomplicated cataract surgery has been well documented in adults. However, pediatric patients are thought to clear residual viscoelastic agents from the anterior chamber more easily than adults, presumably because of healthier trabecular meshwork. (1) We report on a series of 4 eyes of 4 children with previously normal intraocular pressure who underwent cataract extraction with primary (3 patients) or secondary (1 patient) intraocular lens implantation with Healon GV, which was complicated by marked postoperative intraocular pressure elevation (greater than 30 mm Hg). The patients, aged 5 to 14 years, had an intraocular pressure ranging from 34 to 50 mm Hg with Tonopen or applanation tonometry 1 day, postoperatively associated with nausea, eye pain, and microcystic corneal edema. Viscoelastic material was not entirely removed during surgery. Each of these cases occurred after a change in our preferred viscoelastic agent from one with less viscosity to Healon GV. Medical management controlled the elevated intraocular pressure in all cases without affecting the visual outcome. However, 1 patient with intractable nausea and vomiting required hospitalization for rehydration. With meticulous removal of all viscoelastic material at the completion of surgery, we have not documented any additional cases of postoperative pressure elevation.

A 68-year-old man presented with right eye pain and vertigo. Thereafter, he gradually leaned rightward, then laid down. He felt nausea and vomited. His right upper eyelid drooped and he felt dysethesia of the right hand. On neurological examination, ptosis of his right eye with slightly miotic right pupil, paresis of the right soft palate and hoarseness were noted. Arm deviation test demonstrated rightward deviation. He presented sensory ataxia of the right upper and lower extremities: finger nose test showed mild dysmetria of the right upper extremity, heel knee test demonstrated dysmetria of right lower extremity and these findings worsened when he closed his eyes. He showed mild bending of his bilateral ring and little fingers when he did rapid alternative movement. He leaned rightward when he sat and closed his eyes. Position sense of his right upper and lower extremities was decreased and sometimes he could not answer correctly when asked on which direction his finger pointed. Pinprick sensation was mildly decreased on the left side not including the face. Touch and vibration sense were normal. SEP findings on upper and lower extremity stimulation were normal. MRI of the brain showed T2 high intensity and partially T1 low intensity lesion at the right medulla (Figure). MR angiography showed no apparent lesion of major arteries such as dissection of the vertebral arteries. He complained and presented with hiccup initially. On MRI, the lesion was thought to involve the spinothalamic tract, medial lemniscus and inferior olivary nucleus. Ambiguus nucleus was in the lesion and solitary nucleus near the lesion. There is no report that seems to describe clinical features of a lesion like that in this case. Intermediate medullary infarction may present dissociated sensory disturbance like Brown-Sequard syndrome and position sensory disturbance without disturbance of vibration sense.

Temporal arteritis is a rheumatic disease that affects large and medium-sized arteries. It is a severe arteritis involving both the intima and media of the vessel and is a cause of headache that is frequently diagnosed erroneously as "atypical migraine." The patients have a burning or throbbing type of pain. Ultimately, there is localized inflammation or cellulitis over the swollen, tortuous artery. Jaw claudication, eye pain, photophobia, diplopia, and even blindness may accompany the temporal symptoms. As many as 20% to 60% of inadequately treated or untreated patients will lose their vision. Blindness may or may not be preceded by visual symptoms and funduscopic changes. A variety of systemic symptoms are also often present, including nausea, vomiting, chills, dizziness, and loss of weight. Temporal arteritis is not a common diagnosis in maxillofacial practice. We are presenting a case of temporal arteritis diagnosed after a biopsy. The patient eventually lost the vision from one eye.

A 40-year-old man presented with bradycardia, left eye pain, and intermittent nausea 1 day after blunt trauma to the left orbit. Imaging revealed a large orbital floor fracture with significant herniation of orbital contents but no obvious extraocualar muscle entrapment. Oculocardiac reflex was suspected, and the fracture was repaired surgically within 24 hours of presentation. His bradycardia resolved immediately postoperatively. This case is a unique presentation of the oculocardiac reflex in a large orbital floor fracture with significant herniation of orbital contents but without extraocualar muscle entrapment.

A 59-year-old man who had undergone biopsy of cervical lymph node under general anesthesia developed an attack of acute angle-closure glaucoma the night after the surgery. He had had no eye symptoms before. He complained of visual disorder, nausea, eye pain, and dizziness after the surgery. His intraocular pressure in the right eye was high (69 mmHg), and an ophthalmologist diagnosed it as acute angle-closure glaucoma. Dropping lotion in the eyes and the intravenous administration were not effective. His intraocular pressure decreased immediatery after laser iridotomy, and his symptoms improved. When the symptoms of eye pain and visual impairment appeared after the surgery, we should take acute angle-closure glaucoma into consideration and treat it as soon as possible.

Purpose of this study is to determine the types, incidence, and severity of acute complications of intracranial stereotactic radiosurgery (SRS), specifically Gamma Knife (GK). Patients who had never had previous SRS were eligible for this prospective IRB-approved study. The questionnaire used applicable questions from CTCAE v.3.0, the Brief Pain Questionnaire (Short Form), Brief Fatigue Inventory, and the Tinnitus Handicap Inventory. Questionnaires were obtained prior to Gamma Knife (GK), 1 week, 1 month, and 2 months to assess complications. Seventy-six eligible patients (median age of 62 years) had complete data and were analyzed. Diagnoses included: 26 (34%) with brain metastases, 15 (20%) with trigeminal neuralgia, 12 (16%) with schwannoma, 10 (13%) with meningioma, 7 (9%) with arteriovenous malformation, 3 (4%) with pituitary adenoma, and 3 (4%) with other. At 1 week, 24% developed minimal scalp numbness (p =0.0004 baseline compared to 1 week). Only 13% had minimal scalp numbness at 1 month and 2% at 2 months (both p=NS compared to baseline). There was no difference in scalp tingling between baseline and the various time points. Thirteen percent developed pin site pain at 1 week with a median intensity level of 2 out of 10. By one month, only 3% had pin site pain with a median intensity level of 3 out of 10. Four percent developed pin-site infection at 1 week and none at 1 and 2 months. There was no significant difference in nausea from baseline at 1 week, but there was worsening nausea at 1 month (p =0.0114). By 1 month, 10% reported new local hair loss. 23%, 16%, and 15% complained of new/worsening fatigue at 1 week, 1 month, and 2 months, respectively, but 40% reported fatigue at baseline. Balance improved following SRS over all time periods (for all comparisons, p <0.009). 1%, 6%, and 3% developed new tinnitus at 1 week, 1 month, and 2 months, respectively, which was significant when comparing baseline to non-baseline (p =0.0269). Thirty-two patients were employed prior to SRS. Three (9%) patients did not return to work. Twenty-seven (84%) patients returned to work a median of 4 days after SRS. Two people did not report their employment status after SRS. There was no significant difference in face swelling, headache, eye pain, vomiting, seizures, or passing out at any intervals compared to baseline. This prospective study demonstrates that GK is well tolerated with few patients developing major acute effects. Many patients are able to return to work shortly after GK.

A 3-year-old boy presented with severe eye pain and nausea after colliding with a date palm tree branch. Examination under anesthesia revealed a self-sealed corneal laceration and traumatic cataract in his left eye. Cultures were taken and the patient received prophylactic subconjunctival, intravitreal, and systemic antibiotics because of the high risk of endophthalmitis. A thorn from the same tree grew Bacillus cereus. Examination after 2 weeks of the injury revealed a subretinal foreign body (a palm tree thorn), although there were no signs of endophthalmitis or retinal detachment. The patient underwent cataract extraction and laser demarcation of the subretinal foreign body, which was not removed. He was fitted for an aphakic contact lens. With alternate patching, his best-corrected visual acuity improved to 20/30.

Acute angle-closure glaucoma (AACG) is a rare complication of general anesthesia. The coexistence of individual risk factors for postoperative AACG and factors associated with intraocular hypertension are considered to be required for postoperative AACG to develop. We present a case of AACG after general anesthesia for oral bone grafting in a patient with no preoperative eye symptoms. In this case, several factors such as postoperative care in a darkened room, psychological stress, and postoperative hypertension may have precipitated the event in this patient, who may have had preexisting undiagnosed elevated intraocular pressure. The interval between the earliest appearance of symptoms at 9 hours and the ultimate diagnosis was 36 hours. In the postoperative period following general anesthesia, any patient is at risk for AACG. It is important that a postoperative diagnosis of AACG should be considered and a timely consultation with an ophthalmologist be considered if a postoperative patient complains of red eyes, visual disorder, eye pain, headache, and nausea.
