Sexually transmitted diseases (STDs) are now the most common group of identifiable infectious diseases in many countries, especially among those ages 15-50 and in infants. Their control is important considering the high incidence of acute infections, complications and sequelae, their socioeconomic impact, and their role in increasing transmission of the human immunodeficiency virus (HIV). THe worldwide incidence of major bacterial and viral STDs is estimated to be over 125 million cases yearly. STDs are hyperendemic in many developing countries. However, in industrialized countries, the bacterial STDs such as syphilis, gonorrhea, chancroid declined from their peak during WW II until the late 1950s, increased during the 1960s and early 1970s, and have again decreased since that time. In the industrialized world, diseases due to Chlamydia trachomatis, genital herpes virus, human papillomaviruses, and HIV are now more significant than the classical bacterial ones; both groups remain major health problems in most developing countries. Infection rates are similar in both men and women, but women and infants bear the major burden of complications and serious sequelae. Infertility and ectopic pregnancy are often a result of pelvic inflammatory disease and are preventable. STDs in pregnant women can result in prematurity, stillbirth, and neonatal infections. In many areas, 1-5% of newborns are at risk of gonococcal ophthalmia neonatorum, a disease that blinds and congenital syphilis causes up to 25% of perinatal mortality. Genital and anal cancers (especially cervical cancer) are associated with viral STDs (genital human papillomavirus and herpes virus infections). Urethral stricture and infertility are frequent sequelae in men. (author's modified)

Long-term management of cytomegalovirus (CMV) retinitis by intravitreal injection of ganciclovir was evaluated in ten patients with acquired immune deficiency syndrome (AIDS). Patients were unable to tolerate systemic ganciclovir because of severe neutropenia (8 cases), catheter-induced sepsis (1 case), or the need to continue therapy for human immunodeficiency virus (HIV) with zidovudine (ZDV) (1 case). All patients had a favorable response to initial treatment. Cytomegalovirus retinitis progressed in four fellow eyes in which treatment was deferred. Vision improved or remained stable in all but one eye. Patients were followed for a mean of 4 months and received an average of 16.6 intravitreal injections in each eye. Relapse occurred late in the course while on maintenance treatment in five eyes (33%). There was no evidence of toxicity from repeated intravitreal injections. Treatment was very well tolerated. The only severe complication in a total of 249 injections was a single case of Staphylococcus epidermidis endophthalmitis which responded to intravitreal antibiotic treatment. Intravitreal ganciclovir is an effective alternative to systemic ganciclovir in those patients with severe neutropenia and in those patients who desire to remain on systemic ZDV.

We reviewed the records of ocular examinations of patients referred or examined for inflammatory retinal disease over a two-year period and found 18 cases in which retinopathy was documented before the diagnosis of acquired immunodeficiency syndrome (AIDS). Seventeen patients were either homosexual men or intravenous drug abusers. Although 13 patients had AIDS-related complex, no patients met the Centers for Disease Control criteria for AIDS before their ophthalmologic examination. In all 18 cases, the diagnosis of severe immunodeficiency suggestive of infection by the human immunodeficiency virus (HIV) was made by the ophthalmologist. These ophthalmologic findings included five patients with asymptomatic retinal cotton-wool patches, two patients with endogenous Staphylococcus epidermidis bacterial endophthalmitis, and 11 cases of isolated cytomegalovirus retinitis. All patients were ambulatory outpatients at the time of ophthalmologic examination. Noninfectious retinopathy and intraocular opportunistic infections suggest the diagnosis of HIV infection and AIDS, and the ophthalmologist may play an important role in early diagnosis of this disease.

Diagnosis of intraocular inflammations can be difficult, particularly if the patient is suffering from immunodeficiency. Among the endogenous inflammations this applies mainly to cases of hyaloretinitis caused by Candida or other fungi, often presenting as an acute hyalitis with sudden onset; the various ocular complications of AIDS, especially those due to toxoplasmosis (rare) and cytomegalovirus, and lyme disease, which can occasionally cause chronic panuveitis. Among the exogenous cases it applies to postoperative and posttraumatic endophthalmitis. In all these cases the diagnosis has to be established clinically if possible, since, as a consequence of the immunodeficiency, serology is hardly helpful, and only biopsy (of the vitreous) may provide additional information. Rapid diagnosis is very important because of the urgent need for therapy.

A 30-year-old homosexual man with a positive serologic test for human immunodeficiency virus and a history of successfully treated disseminated cutaneous sporotrichosis developed a granulomatous uveitis that worsened with topical and subconjunctival steroid therapy. Culture of the aqueous aspirate yielded Sporothrix schenckii. The patient was treated with intravenous amphotericin B and intravitreal amphotericin B, kanamycin sulfate, and amikacin sulfate. Subsequent aqueous and vitreous cultures were negative, but the intraocular inflammatory process progressed and ultimately led to enucleation of the eye. Histopathologic examination revealed granulomatous inflammation of the anterior uvea and scattered S schenckii in the anterior and posterior chambers. Electron microscopy demonstrated that most of the organisms had disorganized protoplasm. Although treatment failed to ameliorate the progressive intraocular inflammatory process, the negative cultures and the electron microscopic observations suggest that the treatment was reasonably effective in killing S schenckii within the eye. To our knowledge, this is the first case report of S schenckii endophthalmitis in a patient with human immunodeficiency virus infection.

Fusarium is an ubiquitous fungus commonly found in soil and on plants. Human infection usually occurs as a result of inoculation of the organism through the body surface, thus causing skin infection, onychomycosis, keratitis, endophthalmitis and arthritis. Dissemination may occur in subjects with underlying immunodeficiency. Among immunocompromised hosts, Fusarium sp. is an emerging pathogen in neutropenic patients. To our knowledge, since 1973, when the first disseminated fusariosis in a child with acute leukemia was reported, about 80 new cases have been reported, mainly occurring in patients with haematologic malignancies. Specific portals of entry are not well understood, nevertheless the respiratory tract, colonised gastrointestinal tract, onychomycosis, disrupted skin barrier and central venous catheter have been reported as entry sites of deep seated Fusarium infections. Fever, positive blood cultures, severe myalgias, disseminated ecthyma gangrenosum-like skin lesions, ocular symptoms and multiple-organ-system involvement are distinctive features in most cases of disseminated fusariosis. The prognosis is very poor with death generally following despite antifungal therapy, unless an increase in the white blood cell count occurs. All available antifungal drugs show a low activity against the various species of Fusarium. Nevertheless, amphotericin B seems to have the highest in vitro activity and, even if it does not appear to be effective in persistently neutropenic patients, it should be currently considered to be the treatment of choice.

Cytomegalovirus (CMV) retinitis is the most common retinal opportunistic infection in AIDS patients and is the main cause of blindness. It is generally associated with a CD4+ lymphocyte count below 50/microL. CMV retinitis is often asymptomatic (54% of the cases), frequent ophtalmoscopic screening is very important. Two virostatic drugs (Cymevan and Foscavir) have been approved for the treatment of CMV retinitis. Both are effective in preventing the progression of the lesion within 3 weeks of induction therapy. Long-term use of virostatic maintenance therapy delays the onset of relapses. The differential diagnosis of CMV retinitis are: human immunodeficiency virus retinopathy, varicella-zoster virus retinitis, ocular toxoplasmosis, syphilis, candida endophthalmitis in intravenous drug users, and unfrequently, tuberculosis, choroidal pneumocystosis, intraocular lymphoma.

The transmission of infections from the biologic mother to her offspring is popularly known as perinatal infection (PI). It is not synonymous to infections during the perinatal or neonatal period. Physicians should avoid focusing attention only on the TORCH agents in the evaluation of suspected PI. Perinatal period begins from 28 weeks of gestation. Would one consider in utero infections in the first or second trimester of pregnancy as PIs? Developing countries have difficulty in collecting reliable and accurate data of PIs. These data are useful to define the magnitude of the problems, to monitor the trends, to recognise the mode of spread, and to find a solution of PIs. Most PIs are asymptomatic and diagnosis is extremely difficult. Developing countries need rapid, easy-to-operate, simple, and cheap diagnostic tools urgently. Access to health care in the remote city is limited. Newer drugs are too expensive and very few patients can benefit from these. Each developing country should prioritize its PI problems and tackle those that have serious public health problems and socio-economic impact. Most developing countries should focus on HIV (human immunodeficiency virus) and HBV (hepatitis B virus) infections. Other countries where ophthalmia, malaria or tuberculosis are prevalent or endemic, should focus on these. Developing countries are more willing to allocate the budget for prevention of diseases than for treatment. There may be problem of promulgating the information on prevention of diseases because of illiteracy, multi-lingual community. Vaccines where available, should be affordable. Other effective prevention guidelines should be workable in poorer nations. The government should play an important role in enforcing immunisation program by intensive promotion program or by legislation.

Patients with sexually transmitted diseases (STDs) in developing countries are often untreated for long periods of time or receive ineffective treatment, producing complications that can lead to infertility, blindness, and even death. In addition, there is growing research evidence that people with bacterial or viral STDs are more likely to acquire--and perhaps transmit--the human immunodeficiency virus (HIV). STD control programs in developing countries must be reorganized to include: 1) good management of patients with STDs and their contacts, 2) case finding for syphilis in the antenatal population, 3) screenings and case findings for gonorrhea in high-risk groups, and 4) systematic prophylaxis for ophthalmia neonatorum in newborns. Since diagnosis before treatment is problematic in rural areas, the World Health Organization recommends simple treatment protocols based on the most common STD symptoms--urethral discharge; gynecological complaints such as vaginal discharge, low abdominal pain, or dysuria; genital ulceration; and inguinal bubo, a swelling of the lymph nodes in the groin. Other components of this approach include standardized treatment, contact tracing and treatment, health education targeted at high-risk groups, follow-up and case referral where necessary, and the collection of simple statistics on treatment efficacy and STD epidemiology. The incidence of STDs in developing countries is steadily increasing as a result of urbanization, increased numbers of young people, and delayed age at marriage. However, this situation can be combatted through application of treatment protocols, technological advances, improvements in the health care delivery system, and awareness on the part of policy makers of the seriousness of the STD problem.

To describe the pattern of ocular diseases seen during the study period. Retrospective review of surgical pathology and cytology records from January 1991 to December 1999. Reference was also made to case notes where necessary. A total of 225 orbital and ocular surgical pathology specimens were reviewed. One hundred and twenty-five (56.8%) were from males and 100 from females (ratio: 1.3:1). Over 50% of the specimens were obtained from children and young adults less than 20 years of age. There were 168 tumours, with malignancies accounting for 73.8% of all tumours. Other pathological lesions included, inflammatory conditions, benign tumours, and degenerative conditions, which represent 21.8%, 19.6%, and 2.2% of all lesions respectively. Retinoblastoma accounted for 57.3% of all malignancies, the age range was 3 months to 12 years, mean 2.65 years. The modal age was 2 years. Squamous cell carcinoma of the conjunctiva, accounting for 12.1% of all malignancies was the commonest malignancy seen in the adult age group. Malignant melanoma was rare and no case of Kaposi's sarcoma was seen. Commonest non-neoplastic lesions resulting in enucleation of the eye were panophthalmitis and endophthalmitis. Human immunodeficiency virus screening was only done in 3 of 8 patients with squamous cell carcinoma and was positive in 2 of them. Malignancies of the eye and orbit continue to make up majority of orbit and ocular pathologies requiring enucleation in children and young adults. Despite an observed increase in the frequency, insufficient information precludes evaluation of a link between HIV and squamous cell carcinoma as well as other obito-ocular lesions such as Kaposi sarcoma.
