Twenty volunteers were inoculated with various doses of human serum containing Phlebotomus fever virus (Sicilian type) to determine their clinical and serologic responses as well as the human infectious dose50 of the virus. All infected subjects developed fever which varied in duration from 6 to 74 hours. The most common symptoms during sandfly fever were headache, anorexia, myalgia, photophobia, low back and retro-orbital pain. Infected individuals developed a marked leukopenia characterized by an initial lymphopenia followed by protracted neutropenia. Little complement fixing antibody was detected in convalescent sera but most subjects developed significant rises in hemagglutination inhibiting antibodies. All infected subjects developed specific neutralizing antibodies with titers ranging from 1:40 to 1:2,560. Of the three serologic tests performed, the plaque reduction neutralization method appears to be the most sensitive test for detecting antibodies to Phlebotomus fever viruses.

The coexistence in two sisters, born to related parents, of a corticoresistant nephrotic syndrome, lymphopenia, an immune deficit, short stature, and photophobia is described. The immune deficit is mainly cellular; studies of lymphocyte markers demonstrate a pronounced deficiency of T lymphocytes and Fc-mu receptor-bearing cells. It is suggested that a thorough examination of number and function of T cells should be performed in patients with a familial corticoresistant nephrotic syndrome and recurrent infectious episodes before considering immunosuppressive treatment.

We report the ophthalmological and laboratory findings of 6 patients who, after influenza vaccination, were affected by oculorespiratory syndrome (ORS), complaining of red eyes, photophobia, blurred vision, palpebral edema, ocular pain and itching, and conjunctival secretions. The conjunctivae were mildly hyperemic with few follicles, but the ophthalmological examination findings were otherwise normal. Patients had lymphopenia and decreased levels of the total hemolytic complement and the third and fourth component of the complement. We conclude that ORS causes conjunctivitis and seems to involve the complement.

Sulfur mustard is an alkylating agent that reacts with ocular, respiratory, cutaneous, and bone marrow tissues, resulting in early and late toxic effects. We compare these effects based on the experience in Iranian veterans exposed to the agent during the Iran-Iraq conflict (1983-88). The first clinical manifestations of sulfur mustard poisoning occurred in the eyes with a sensation of grittiness, lacrimation, photophobia, blepharospasm, and corneal ulceration. Respiratory effects appeared as rhinorhea, laryngitis, tracheobronchitis, and dyspnoea. Skin lesions varied from erythema to bullous necrotization. Initial leukocytosis and lymphopenia returned to normal within four weeks in recovered patients, but marked cytopenia with bone marrow failure occurred in fatal cases. Late toxic effects of sulfur mustard were most commonly found in lungs, skin and eyes. Main respiratory complications were chronic obstructive pulmonary disease, bronchiectasis, asthma, large airway narrowing, and pulmonary fibrosis. Late skin lesions were hyperpigmentation, dry skin, atrophy, and hypopigmentation. Fifteen of the severely intoxicated patients were diagnosed with delayed keratitis, having corneal vascularization, thinning, and epithelial defect. Respiratory complications exacerbated over time, while cutaneous and ocular lesions decreased or remained constant. Both the severity and frequency of bronchiectatic lesions increased during long-term follow-up. The only deteriorating cutaneous complication was dry skin. The maximum incidence of delayed kaeratitis was observed 15 to 20 years after initial exposure. Being suggested as the main cause ofassociated with malignancies and recurrent infections, natural killer cells were significantly lower 16 to 20 years after intoxication.

An 18-year-old woman presented with a progressively worsening headache, photophobia feverishness and vomiting. Three weeks previously she had returned to the UK from a trip to Peru. At presentation, she had clinical signs of meningism. On admission, blood tests showed a mild lymphopenia, with a normal C reactive protein and white cell count. Chest X-ray and CT of the head were normal. Cerebrospinal fluid (CSF) microscopy was normal. CSF protein and glucose were in the normal range. MRI of the head and cerebral angiography were also normal. Subsequent molecular testing of CSF detected enterovirus RNA by reverse transcriptase PCR. The patient's clinical syndrome correlated with her virological diagnosis and no other cause of her symptoms was found. Her symptoms were self-limiting and improved with supportive management. This case illustrates an important example of viral central nervous system infection presenting clinically as meningitis but with normal CSF microscopy.
