Ocular viral infections are a major cause of loss of vision and their effective control by applications of chemical compounds has been extensively investigated. To achieve such a control, better understanding of virus-host-drug interactions become a necessity. Two models, hamster and rabbit cornea, were selected for assays of protection afforded by tilorone dihydrochloride against herpes simplex (HSV) and vesicular stomatitis viruses (VSV). To obtain basic biologic comparison between viral interference and interferon-induction by tilorone, the hamster cornea system was first studied to produce a mutual viral interference by double infection. Furthermore, its effect against ascending herpetic ocular infection into encephalitis was evaluated in the rabbit. This compound was reported to have promising results in improving manifestations such as corneal ulceration, uveitis and conjunctivitis.

A review of the medical literature and two case reports of M. pneumoniae infections with exanthems are presented. Erythematous maculopapular and vesicular exanthems were most common. The duration of rash was more than seven days in the majority of instances, and most patients had associated pneumonia. A striking difference in prevalence and clinical symptomatology by sex was noted; 16 of 20 patients analyzed were males, and they frequently dad severe mucocutaneous syndromes. In contrast, severe conjunctivitis, generalized ulcerative stomatitis, and vesicular or bullous exanthems were not seen in females. Clinicians should suspect infection with M. pneumoniae in patients with exanthem and pneumonia, although other etiologic possibilities should also be considered.

Twenty-seven (10%) of 271 infants and children with acute otitis media (AOM) were found to be infected with cytomegalovirus (CMV) or herpes simplex virus type 1 (HSV). CMV or HSV, alone or in combination with bacteria or other viruses, was isolated from the middle ear fluid (MEF) of 10 patients. In three cases, CMV alone was isolated from the MEF, and in one case, HSV alone was isolated. One of the CMV cases involved an acute primary or reactivation of CMV infection, with CMV-bacterial otitis and conjunctivitis as major manifestations. One patient with AOM and stomatitis had purulent otitis associated with the presence of HSV in MEF, with no other bacterial or viral pathogens noted in MEF or nasal wash specimens. While most patients with CMV infection were probably asymptomatic excreters at the time of development of AOM, CMV did enter the middle ear. The presence of CMV in MEF was prolonged, and the patients continued to have clinical signs of otitis despite negative bacterial cultures. Among patients with bacterial otitis, a higher proportion of those who had CMV found only in nasal wash specimens had persistent bacteria in MEF, compared with those who were concurrently infected with other viruses (57% vs. 19%; P less than .04). This report is the first to suggest an etiologic role for CMV and HSV in AOM.

A 63-year-old man, who had for one month been on sulfasalazine therapy, developed general malaise, high fever, severe stomatitis, and bilateral necrotizing pseudomembranous conjunctivitis with corneal erosion, identical to that seen in the Stevens-Johnson syndrome. Topical therapy with antibiotics and aprotinin rapidly healed the corneal surfaces, while densely adherent true membranes developed on the conjunctiva, and were removed surgically several times during the next week. After the acute stage, subtle subepithelial conjunctival scarring, superficial punctate keratitis, dry eye syndrome and fluctuating irregular corneal astigmatism became evident, but good visual acuity, lid function and ocular motility were retained. Histopathologic study of conjunctival membranes from two cases of membranous conjunctivitis revealed polymorphonuclear leukocytes within a matrix composed of fibrin, tenascin and fibronectin. In older membranes, histiocytes were additionally found. Surgical debridement of such membranes removes a substratum of inflammatory debris that is likely to promote secondary infection, fibrosis and symblepharon formation, and may decrease rather than increase subsequent scarring of the necrotized conjunctiva.

A 10-year-old boy who had portal hypertension secondary to portal fibrosis/intrahepatic biliary atresia developed syncopal episodes related to strenuous activity. A work-up excluded a metabolic or neurologic etiology and cardiac catheterization demonstrated significant pulmonary hypertension. Six months later he died and an autopsy revealed pulmonary plexogenic arteriopathy without microemboli. Previous reported cases of this symptom complex are reviewed. In addition, he had a history of nonspecific colitis, ulcerative stomatitis, and conjunctivitis responsive to steroid therapy. The possible relationship of these manifestations to the portal pulmonary pathology is discussed.

Two groups of cats were inoculated oro-nasally with one of two isolates of feline calicivirus (FCV) from clinical cases of chronic stomatitis. All cats developed signs typical of acute FCV infection; namely, ocular and nasal discharge, conjunctivitis, and marked oral ulceration. None of the cats shed virus beyond 28 days. Seronegative control cats were then infected with a lower dose of one isolate, but again only acute signs were seen and no carriers produced. The original cats were then re-infected with the heterologous isolate. As before, only signs of acute disease were seen, but the range of clinical signs and severity was reduced. Virus shedding patterns in one group were similar to those seen originally, but in the other the duration was reduced. No chronic stomatitis developed over the 10 months of the study. Serum virus neutralising and serum and salivary class specific immunoglobulin responses were investigated. Although long-term carriers were not induced, no relationship between cessation of virus shedding in an individual animal and systemic and local antibody responses was seen.

Twenty-eight patients with refractory advanced malignancies were treated with a 24 hr infusion of 5-fluorouracil (5-FU), Leucovorin (LV), and N-(phosphonacetyl)-L-aspartic acid (PALA) weekly. Twenty-seven patients were evaluable for the assessment of toxicity and anti-tumor activity. PALA was administered as intravenous bolus over 15 min at a fixed dose, 250 mg/m2 24 hr before the start of 5-FU and LV infusions. 5-FU was initially administered at 750 mg/m2 and was incrementally increased to 2600 mg/m2. LV was administered in a fixed dose of 500 mg/m2 concurrently with 5-FU over a 24-hr period. The course was repeated weekly. Diarrhea, stomatitis, nausea, and vomiting were among dose-limiting toxic effects. Other toxicities observed were hand-foot syndrome, hair loss of scalp/eyelashes, overall weakness, rhinitis, and chemical conjunctivitis. Maximum tolerated dose (MTD) of 5-FU in this combination and schedule was 2600 mg/m2. Seven of 14 patients treated at 2600 mg/m2 were able to tolerate the chemotherapy on a weekly basis without interruption. The other seven patients required dose de-escalation, a majority of whom contained 5-FU at a dose of 2100 mg/m2. Twenty-three of 27 patients had been previously treated. Eight patients achieved a partial response, all of whom were previously treated, except three patients. A complete response was observed in a patient with pancreatic carcinoma, previously untreated. Overall response rate for the patients who were treated at the 5-FU dose of 2100 mg/m2 or 2600 mg/m2 is 9 of 18 patients (50%).

Twenty-eight patients with refractory advanced malignancies were treated with a 24-hour infusion of 5-fluorouracil (5-FU), leucovorin (LV), and N-(phosphonacetyl)-L-aspartic acid (PALA) weekly. Twenty-seven patients were evaluable to assess toxicity and antitumor activity. The PALA was administered as an intravenous bolus over 15 minutes at a fixed dose (250 mg/m2) 24 hours before the start of the 5-FU and leucovorin infusions. Initially the dose of 5-FU was 750 mg/m2; this was increased incrementally to 2600 mg/m2. The LV was administered in a fixed dose of 500 mg/m2 concurrently with the 5-FU over a 24-hour period. This regimen was repeated weekly. Diarrhea, stomatitis, nausea, and vomiting were among the dose-limiting toxicities. Others were hand-foot syndrome, hair loss of the scalp and eyelashes, overall weakness, rhinitis, and chemical conjunctivitis. The maximum tolerated dose of 5-FU in this combination and schedule was 2600 mg/m2. Seven of 14 patients treated with 2600 mg/m2 were able to tolerate the chemotherapy on a weekly basis without interruption. The other seven patients required dose reductions, but most received 5-FU at a dose of 2100 mg/m2. Twenty-three of 27 patients were treated previously. Eight patients had a partial response; five of these were treated previously. A complete response was observed in one patient with pancreatic carcinoma, previously untreated. The overall response rate for patients treated with 2100 or 2600 mg/m2 of 5-FU was nine of 18 patients (50%). Three of four previously untreated patients with pancreatic cancer responded to this treatment (two responded partially, and one had a complete response). One of three heavily pretreated patients with non-small cell lung cancer had a partial response as did a patient with breast cancer. Four of ten patients with colorectal cancer responded to the treatment (four partial responses), of whom three had been treated previously.

On the basis of a literature review and eight cases of our own, we analyzed 37 cases of Mycoplasma pneumoniae (MP) infection and Stevens-Johnson syndrome (SJS). Our clinical and laboratory findings do not differ from those reported in the literature for MP infection with no exanthem or for SJS of various etiologies. Eighty percent of the children presented with symptoms of upper respiratory tract infection (URTI) (cough, fever, sore throat, malaise, headache), with a mean of 10 days (range 1 to 30) before skin rash broke out. Skin manifestations occurred in 94.2% of the patients after 3 to 21 days (mean 10.3 days) of fever. The exanthem, composed predominantly of maculopapular and vesicular, was distributed chiefly on the trunk and extremities and lasted less than 14 days in 87.8% of the patients. Stomatitis was observed in 91.6% of the patients and conjunctivitis in 50%. No consistent pattern seems to emerge by which one could predict the existence of MP infection causing SJS. The complications of SJS associated with MP seem less frequent (2.7%) and much less severe than in cases where SJS arises from other reported causes. Because coincidence cannot be excluded from the assessments of the degree and rate of improvement for the few patients treated with corticosteroid, from the low frequency of complications, and from the mortality rate of zero in this series of patients, the use of corticosteroids for SJS associated with MP infection is questionable.

This rare disorder characterized by regular periodic oscillations in the number of peripheral neutrophils from normal to neutropenic levels. A case of a fourteen years old boy is presented who developed the disease at age of four years. Neutropenic periods appeared at intervals of 21 days and were associated with recurrent infections--gingivitis, stomatitis, conjunctivitis. The possible mechanism of impaired granulopoiesis and different therapeutic approaches are discussed.
