Psoralen photochemotherapy (PUVA) is a combination of orally administered psoralen and long wave ultraviolet-A radiation (UVA), and is one of the most effective forms of therapy for psoriasis. The unwanted effects of PUVA therapy can be divided into short and long term adverse effects. The short term adverse effects include erythema, pruritus, nausea and headache. While short term adverse effects are limited and reversible after discontinuation of treatment, potential long term adverse effects such as chronic actinic skin damage, dyskeratotic and precancerous skin conditions, nonmelanoma skin cancer, immunological alterations and cataract formation are of greater concern. Long term risks associated with PUVA therapy can be minimised by several measures. Careful patient selection is mandatory; for example, patients with chronic actinic damage and a history of skin cancer may bear a higher risk for the development of new cancers, and previous arsenic intake and ionising radiation also increase the risk of nonmelanoma skin cancers. Certain drug combinations make it possible to lower the UVA dose, which is important because of the dose-dependent increase in the incidence of squamous cell carcinomas in patients treated with PUVA. It has been demonstrated that 200 treatments or a total UVA dose of 1200 J/cm2 seems to be the threshold for development of nonmelanoma skin cancer. Shielding male genitalia during PUVA treatment is essential because of the increased risk of genital squamous cell carcinomas. Yearly dermatological examination to detect skin cancer at an early stage is highly advisable. Sunscreen use, protective clothing and avoidance of sun exposure reduce the uncontrolled dose of solar UV radiation. Other psoralens with a less carcinogenic potential can be used. UVA-opaque sunglasses during the entire period of increased photosensitivity after psoralen ingestion help avoid cataract formation. Assignment to PUVA ought to be based on the risk-benefit ratio for the individual patient and should be limited to those who can be monitored and controlled by informed, competent and conscientious physicians.

Two hundred and thirty-one patients were questioned the day following their cataract surgery to ascertain the incidence of postoperative morbidity. One hundred and nineteen patients received local anaesthesia (LA) and 112 received general anaesthesia (GA). There was a significant difference in the incidence of nausea (21% in GA group, 3% in LA group, p < 0.01), sore throat (41% GA group, 3% LA group, p < 0.01), and bruising of the eye (15% GA group, 39% LA group, p < 0.01). There was no significant difference in the incidence of vomiting, headache, double vision, the severity of postoperative pain, or the need for analgesia. The time before the patients drank and ate postoperatively was significantly shorter in the local anaesthetic group (1.3 h and 1.8 h LA group, 4.1 h and 6.7 h GA group respectively, p < 0.01).

The study was conducted from November 1995 to May 1996 at the one general hospital in Seoul. The total subjects of this study were 412 patients who have the experience of fall accident, among them 31 was who have fallen during hospitalization and 381 was who visited emergency room and out patient clinic. The purposes of this study were to determine the characteristics, risk factors and results of fall accident and to suggest the nursing strategies for prevention of fall. Data were collected by reviewing the medical records and interviewing with the fallers and their family members. For data analysis spss/pc+ program was utilized for descriptive statistics, adjusted standardized X2-test. The results of this study were as follows: 1) Total subjects were 412 fallers, of which 245 (59.5%) were men and 167 (40.5%) were women. Age were 0-14 years 79 (19.2%), 15-44 years 125 (30.4%), 45-64 years 104 (25.2%), over 65 years 104 (25.2%). 2) There was significant association between age and the sexes (X2 = 39.17, P = 0.00). 3) There was significant association between age and history of falls (X2 = 44.41, P = .00). And history of falls in the elderly was significantly associated with falls. 4) There was significant association with age and medical diagnosis (X2 = 140.66, P = .00), chief medical diagnosis were hypertension (34), diabetes mellitus (22), arthritis (11), stroke (8), fracture (7), pulmonary tuberculosis (6), dementia (5) and cataract (5). 5) There was significant association between age and intrinsic factors: cognitive impairment, mobility impairment, insomnia, emotional problems, urinary difficulty, visual impairments, hearing impairments, use of drugs (sedatives, antihypertensive drugs, diuretics, antidepressants) (P < 0.05). But there was no significant association between age and dizziness (X2 = 2.87, P = .41). 6) 15.3% of total fallers were drunken state when they were fallen. 7) Environmental factors of fall accident were unusual posture (50.9%), slips (35.2%), trips (9.5%) and collision (4.4%). 8) Most of falls occurred during the day time, peak frequencies of falls occurred from 1 pm to 6 pm and 7 am to 12 am. 9) The places of fall accident were roads (22.6%), house-stairs (16.7%), rooms, floors, kitchen (11.2%), the roof-top, veranda, windows (10.9%), hospital (7.5%), ice or snowy ways (5.8%), bathroom (4.9%), playground, park (4.9%), subway-stairs (4.4%) and public-bathrooms (2.2%). 10) Activities at the time of fall accident were walking (37.6%), turning around or reaching for something (20.9%), going up or down stairs (19.2%), exercise, working (17.4%), up or down from a bed (2.7%), using wheelchair or walking aids, standing up or down from a chair (2.2%) and standing still (2.2%). 11) Anatomical locations of injuries by falls were head, face, neck (31.3%), lower extremities (29.9%), upper extremities (20.6%), spine, thorax, abdomen or pelvic contents (11.4%) and unspecified (2.9%). 12) Types of injures were fracture (47.6%), bruises (13.8%), laceration (13.3%), sprains (9.0%), headache (6.6%), abrasions (2.9%), intracranial hemorhage (2.4%) and burns (0.5%). 13) 41.5% of the fallers were hospitalized and average of hospitalization was 22.3 days. 14) The six fallers (1.46%) died from fall injuries. The two fallers died from intracranial hemorhage and the four fallers died of secondary infection; pneumonia (2), sepsis (1) and cellulitis (1). It is suggested that 1) Further study is needed with larger sample size to identify the fall risk factors. 2) After the fall accident, comprehensive nursing care and regular physical exercise should be emphasized for the elderly person. 3) Safety education and safety facilities of the public place and home is necessary for fall prevention.

Dexamethasone-cyclophosphamide pulse (DCP) is the prefered mode of therapy in pemphigus in India because it is relatively free from the side effects seen with heavy doses of daily oral steroids. One hundred forty-six pemphigus patients treated with DCP were observed for side effects of this regimen. One hundred forty mg of dexamethasone was administered IV in 200 ml of 5% dextrose over a period of 60-90 minutes on 3 consecutive days. Five hundred mg of cyclophosphamide was added on first day of the pulse and 50 mg given orally daily in the intervening period. DCP was repeated every 4 weeks and continued for 6 months after subsidence of the disease (no new lesions). Flushing over the face was the most common event recorded during the adiministration in 78 subjects followed by palpitations in 11, hiccups in 9, and numbness of feet in 6. Fourteen patients had polyurea, and 3 developed skin rash. Shivering, shooting pains along thighs, breathlessness, seizure and unilateral limb edema were observed in one patient each. Generalized weakness/malaise was the most troublesome delayed side effect in 81 (55.4%) patients; it lasted for 8-15 days after the pulse. Thirty-six (24.6%) had inadequate sleep syndrome, 23 (15.7%) had headache, 21 (14.3%) complained of arthralgias, 19 (13%) experienced alteration in taste, and 13 (9%) had diffuse hair loss. 28 females developed menstrual disturbances, and 14 (9.5%) had blurring of vision (glaucoma in 3 and posterior subcapsular cataract in 1). Thirteen of eighteen diabetics had an increase in blood sugar requiring higher doses of insulin. Five NIDDM patients needed insulin. Four (2.7%) developed hypertension. Pulse therapy is not absolutely free from side effects. Hypertension and diabetes occur less frequently as compared to conventional steroid therapy. Generalized weakness, flushing, headache and taste alteration occur exclusively with pulse therapy.

Meares-Irlen syndrome is characterised by symptoms of eye strain, headaches and visual perceptual distortions when viewing text. The symptoms are alleviated with individually prescribed coloured filters, such as precision tinted lenses. Meares-Irlen syndrome, and the related condition of visual stress, are likely to result from hyperexcitability of the visual cortex, which can also occur in migraine. The symptoms of Meares-Irlen syndrome and visual stress are non-specific and the condition needs to be differentially diagnosed from other optometric conditions, such as refractive error, binocular vision anomalies, and accommodative anomalies. Three case reports are described of patients who consulted the author with suspected Meares-Irlen syndrome but were found to have other causes for their symptoms: posterior sub-capsular cataract, high uncorrected astigmatism, and decompensated convergence weakness exophoria. These cases highlight the need for professional eye care for people with suspected Meares-Irlen syndrome. Although this advice is stressed in literature on the well-established MRC/Wilkins Intuitive Colorimeter system, it is not always stressed in literature about other systems. This may be a cause for concern.

Tobacco consumption is the leading preventable cause of disease, disability, and premature death but little is known about its deleterious effect on the ocular health of workers handling tobacco. The goal of this study was to identify probable effects of occupational tobacco exposure among south Indian bidi-industry workers. This study included 310 females (mean age, 34.8 +/- 10.9 years) actively involved in bidi-rolling presenting with eye symptoms to a tertiary eye care hospital. Results suggested that a wide spectrum of ocular complications exist among these workers. Common ocular symptoms were defective vision, dull-aching headache and eye irritation. The main ocular findings were papillary conjunctival hyperplasia, hyperpigmentation of ocular surface, punctate epithelial erosion or superficial punctate keratitis, cataract or pseudophakia and segmental optic atrophy. Abstaining from work, supplementation of Vitamin B complex rich in B 12 and appropriate surgical or medical management reversed visual loss due to corneal disease or cataract but was not effective in optic neuropathy.

Cluster headache (CH) consists of attacks of severe, unilateral orbital/supraorbital/temporal pain, lasting for 15-180 min, occurring once or more times a day, and associated with ipsilateral conjunctival injection, lacrimation and other symptoms. Cataract is clouding of the lens of the eye causing a progressive and painless loss of vision. We describe the cases of two men (not relative, but with the same last name, which originates from north-eastern Italy) that in young adult age, after years of suffering from chronic CH, developed cataract on the same side of the pain attacks. Patient 1 was diagnosed as having cataract 18 years after the onset of episodic (and subsequently chronic) CH. Patient 2 began suffering from chronic CH at the age of 44 years and after 8 years he developed cataract. This is the first report of cataract in patient suffering of CH and occurring in the eye affected by the pain attack.

We report a rare brain developmental anomaly in Usher's syndrome. We present a 43-year-old male with visual disturbance, hearing loss, and headache. Retinitis pigmentosa and sensorineural hearing loss were determined and he was diagnosed with Usher's syndrome according to the clinical findings. Magnetic resonance imaging showed an arachnoid cyst on the left temporal lobe, cavum septum pellucidum et vergae. Uneventful cataract surgery was performed in both eyes. He was suggested to be followed up periodically for the arachnoid cyst and to use a hearing device. Although auditory and visual disturbances are the typical findings of this syndrome, it may affect other parts of the central nervous system as well. Morphological abnormalities of central nervous system and related disorders can be seen in patients with Usher's syndrome.

A 73-year-old man presented with uveitic glaucoma associated with headache. Because there were no active inflammatory signs, synechiolysis and cataract extraction were performed. Even after lowering intraocular pressure, he repeatedly complained of headache, but no neuroimaging was performed. Acute bilateral visual loss was occurred 3 months after cataract surgery. Ophthalmologic examination revealed bilateral optic neuritis and a Gd-DPTA-enhanced cranial magnetic resonance imaging (MRI) showed thickened enhancement of the dura and optic nerve sheath. A final clinical diagnosis of idiopathic hypertrophic pachymeningitis associated with optic neuritis was made.
