Intravenous immunoglobulin Normal immunoglobulin is predominantly IgG and is obtained from the pooled serum of >1000 blood donations acne x lactoferrin order bactroban cheap online. X-linked hypogammaglobinaemia; • Rarely acne 5 order cheap bactroban, prophylaxis following infectious contact in immunocompromised skin care vitamin c purchase 5 gm bactroban otc. Irradiated blood products (inactivates T lymphocytes) these are required in: • Intrauterine and neonatal exchange transfusions acne 19 year old male bactroban 5 gm low cost. Signs and symptoms of intravascular haemolysis may appear after only 5–10mL blood infusion with: • Pain at venepuncture site acne facials discount 5 gm bactroban with amex. Bacterial infected blood products Most serious reactions are seen with platelets (kept at room temperature where bacteria can multiply and produce toxins). Fever and rigors occur within few hours of starting or completing the transfusion. Lymphocytes in donor unit ‘engraft’ leading to rash, diarrhoea, liver impairment, and bone marrow failure. Causes of cancer in childhood Environmental factors do not appear to be clearly linked with childhood cancer. Also be aware that childhood malignancy may present with a variety of clinical features and so special attention should be paid to the following. Respiratory symptoms New episode of wheeze (usually monophonic and xed) may be caused by intrathoracic mass. Treatment with oral steroids, based on a presumptive diagnosis of asthma, may lead to partial response in symptoms and therefore delay the diagnosis of leukaemia or lymphoma involving mediastinal lymphadenopathy compressing the airways. Bone and joint pain/swelling Persistent back pain should not be dismissed as innocent in children. It may reect bone pain of bone marrow expansion (leukaemia or bone marrow metastases) or a spinal tumour. Raised intracranial pressure the most common presenting features of brain tumours are: • Headache (typically on waking). Lymphadenopathy Malignancy accounts for a small proportion of cases of persistent lymphadenopathy in children. Possible diagnoses include acute leukaemia, nonHodgkin’s lymphoma, Hodgkin’s disease, metastases from neuroblastoma or sarcoma. Features of enlarged lymph node that should raise concern • Diameter >2cm • Persistent or progressive enlargement • Non-tender, rubbery, hard, or xed • Supraclavicular or axillary position • Associated with other features. Neurological signs the following should raise suspicion of a brain tumour: • Cranial nerve decits from direct tumour involvement. Pancytopenia Not all cell lines are equally affected, but the following problems occur as leukaemia or disseminated malignancy displaces normal bone marrow. The following tests are used in diagnosis, staging, and assessment for prognosis, and as a baseline before starting treatment. Imaging Sedation or general anaesthetic may be needed in young children when performing these procedures. The cause is unknown, but in a minority it is associated with chromosomal aberrations. Possible links to patterns of childhood infection acting as a trigger have been hypothesized. Presentation Typically with a short history (days or weeks), and with symptoms and signs reecting pancytopenia, bone marrow expansion, and lymphadenopathy. Includes petechiae, bruising, pallor, tiredness, bone/joint pain/swelling, limp, lymphadenopathy, airway obstruction, and pleural effusion. Specic diagnostic tests • Bone marrow: morphology; immunophenotype; cytogenetics. Treatment is stratied according to risk factors, which include: • Time from rst diagnosis (risk reduces with time). Children with Down syndrome-associated leukemia experience more complications of treatment. Chronic myeloid leukaemia (adult type) Classically associated with Philadelphia chromosome +ve disease (t(9;22) translocation). It has a chronic phase with non-specic symptoms (fever, night sweats, and hepatosplenomegaly). The majority are high-grade tumours that are divided into categories, using histology, immunophenotype, and cytogenetics (see Box 18. Investigations • Tissue: bone marrow aspirate; lumbar puncture; pleural and abdominal (peritoneal) uid aspirate; exclusional biopsy. Mature B cell disease is treated with short series of dose-intensive courses of chemotherapy. The histology shows Reed–Sternberg cells in an apparently reactive lymph node inltrate. Presentation Progressive, painless lymph node enlargement, the most common sites being cervical (80%) and mediastinal (60%). Dissemination to extranodal sites is less common, lungs and bone marrow being most frequently involved. Fever, night sweats, weight loss (>10%) constitute ‘B’ symptoms and are common in advanced stages. Treatment National practices differ, inuenced by the balance between cure and adverse long-term effects. Low stage disease may be cured with involved eld radiotherapy alone, but chemotherapy with low dose involved eld radiotherapy for selected cases is now more commonly employed. Relapse Cure is still possible with second line therapy, including autologous stem cell transplant. Raised intracranial pressure this requires prompt treatment: • Referral and transfer to a paediatric neurosurgical unit. Posterior fossa lesions can be cured with surgery alone, whereas optic pathway tumours are relatively inaccessible and morbidity is high. Treatment usually includes radiotherapy, with the addition of temozolamide or other agents in the context of clinical trials Diffuse brainstem glioma • Glioma in the region of the pons, usually high-grade and inoperable. Additional chemotherapy carries a survival advantage, allowing reduction in drug dose and/or eld of radiotherapy, particularly in younger patients. Complications include damage to the hypothalamic–pituitary structures, vision, and behaviour. Retinoblastoma (3% of all tumours) • Sporadic or familial (40%) forms that are unilateral or bilateral (30%) on presentation. Sites of involvement include: • the adrenal glands (32%); • the sympathetic chain: • abdomen (28%); • thorax (15%); • pelvis (6%); • neck (2%). May be locally invasive; surrounds, rather than displaces vessels and other structures. Depends on site, spread, and metabolic effects: • Palpable mass (may be painless). Targeted antibody treatment is increasingly employed as part of the approach to treatment in the context of clinical trials. Prognosis Disseminated neuroblastoma only cured in 20–30%, despite intensive treatment. Relapse treatment Options include further surgery, chemotherapy, and/or radiotherapy, depending on p treatment. After previous high dose chemotherapy and stem cell transplant, cure is unrealistic. Site Bilateral cases are unusual and more often associated with genetic predisposition. In bilateral (stage V) disease, the aim is to maximize response to chemotherapy prior to performing bilateral nephron-sparing surgery. Carboplatin, cyclophosphamide, and etoposide are usually reserved for unresponsive or recurrent disease. Nephroblastomatosis Multiple foci of premalignant tissue, also known as nephrogenic rests, characterize this condition. The condition is associated with Wilms’ tumour, but may exist without tumour formation (seen on 1% of routine post-mortem examinations). Other renal tumours in childhood Mesoblastic nephroma Occurs in infants and is treated with surgery; chemotherapy is only indicated for incompletely excised cases. They are histologically distinct, with different patterns of disease and response to treatment. Osteosarcoma Presentation Localized pain and swelling, pathological fracture, and rarely erythema. Metastases • Seen at diagnosis in 15–25% of cases • Lungs most common site, followed by bones. Prognosis Adverse outlook is associated with: • Inability to resect primary tumour. Radiotherapy is an effective adjunct, and an alternative to surgery, particularly at axial sites. Prognosis Adverse outlook associated with: • large primaries; • axial sites; • poor response to induction chemotherapy; • metastatic disease. Bony metastases confer a particularly grave prognosis with <20% longterm survivors. Second-line chemotherapy may include combinations involving Etoposide, carboplatin, cyclophosphamide, topotecan and ironotecan. Presenting features Mass, pain and obstruction of: • bladder; • pelvis; • nasopharynx; • parameningeal; • paratestis; • extremity; • orbit; • intrathoracic. Treatment • Chemotherapy (6–9 courses) with ifosfamide or cyclophosphamide, actinomycin, vincristine, anthracyclines. Prognosis Ranges from <10% survival for bony metastatic disease to >90% for excised paratesticular tumours. Metastases are rarely present at diagnosis (lungs, the commonest site, bone, and bone marrow). Treatment of extracranial tumours • Surgery followed by observation for low risk tumours. Sacrococcygeal teratomas should be removed together with the coccyx to reduce risk of malignant relapse. Malignant melanoma Risk factors include: • pre-existing conditions; • giant congenital naevi; • dysplastic naevus syndrome; • xeroderma pigmentosum; • albinism; • immunosuppressive diseases. Phaeochromocytoma Tumours in the adrenal medulla and sympathetic ganglia are usually sporadic, but may be associated with von Hippel–Lindau disease and multiple endocrine neoplasia types 2a and 2b (see b p. May present with precocious puberty, inappropriate virilization in females (see b p. Single-system disease is usually conned to bone, occasionally to skin, and seen more in older children. The natural history varies from spontaneous resolution to repeated recurrence, or death. Presentation Depends on site of disease, but may include: • Pain or lump associated with isolated bony disease (most common). Diagnosis can be made without biopsy in the presence of characteristic pituitary/hypothalamic abnormality, where biopsy considered too hazardous, or of lytic bone lesions with clinical features suggesting spontaneous resolution.
Although low pressures are preferred in the dialysate side of the system 195 (to promote ultrafiltration) acne 40 year old woman buy bactroban 5gm visa, increasing the dialysate pressure could reduce the filtration rate in desired circumstances Blood priming Blood priming refers to acne free order bactroban 5gm otc filling the circuit volume with blood prior to acne 9 days before period generic bactroban 5gm amex its connection to acne in early pregnancy best buy for bactroban the patient circulation acne underwear purchase bactroban on line amex. It is particularly needed when the circuit volume exceeds 10-15% of the estimated blood volume of the child. Heparin is given continuously at a rate of 10-20 units/kg/h after a bolus of 20-30 units/kg. Sodium citrate is delivered to the initial part of the circuit providing a local anticoagulation effect. Citrate is converted to bicarbonate in the liver which could cause metabolic alkalosis. Be careful in patients with hepatic insufficiency because citrate overload could cause metabolic acidosis. Conversion of lactate to bicarbonate in the liver limits the use of lactate based solutions in 196 patients with associated liver impairment. Furthermore, due to its vasodilator properties and non-physiologic pH, lactate could cause hypotension and worsen acidosis due to accumulation of lactate. The lack of urea and other non-desired metabolic byproducts in the dialysate solution creates a concentration gradient by which these solutes are cleared from the blood. High concentrations of urea, potassium and phosphorus in blood of patients with renal failure are easily eliminated through the membrane both by convection (ultrafiltrate) and diffusion (low or physiologic concentrations in the dialysate solution). Bicarbonate-based fluid is preferred over lactate-based due to the risk of metabolic acidosis leading to cardiac dysfunction, vasodilatation, and hypotension. Albumin can be added to the dialysate fluid to help eliminate protein bound drugs. Circuit flow rate Blood flow (Qb) should be started below the goal rate and advanced to maximum rate over 30 min. Flow rates vary from to 10-12 mL/kg/min in neonates and 2-4 mL/kg/min in older children and adolescents. Low arterial pressures may be due to hypotension, kinks in the tubing system, catheter malfunction or stenosis of the arterial inflow. Venous hypertension may be due to clotting of the dialyzer/membrane, kinks in the tubing system or stenosis of the venous outflow. Neonates and children up to 6 kg usually require 7 Fr, 6 to 15 kg require 8 Fr, 15 to 30 kg require 9 Fr and >30 kg 10 Fr catheters. Determinations of daily urea clearance are derived by the following formula: Daily total Kt/Vurea = peritoneal Kt/Vurea + renal Kt/Vurea Where: K=clearance of urea, t=time (min), V=volume of distribution Adequate dialysis is a term employed to describe the effects of a dialysis dose by returning the patient with renal failure to almost physiologic parameters of kidney function and keeping him/her asymptomatic. Optimal dialysis is used to describe the reduction in morbidity and/or mortality with a determined dose of dialysis keeping in mind the financial burden or excessive workload if the dose is increased. Proteinuria (more specifically albuminuria), which is determined by the ratio of the concentration of albumin to creatinine in spot urine. Protein content in urine varies at different times of the day and proteinuria has been reported as high as in 10% of normal children but only less than 1% of these have persistent proteinuria. This extensive absorptive surface allows for an effective exchange of water and solutes and transfer of proteins and cells in normal circumstances. Its large surface is mainly due to the existence of microvilli which, along with tight 202 intercellular junctions of the mesothelial cells are in charge of most transport mechanisms. Aquaporin channels have been identified and believed to be responsible for at least 50% of the water transport through the peritoneum. The intraperitoneal catheter segment may be straight or coiled with 203 multiple side holes of about 500 microns in diameter. Coiled catheters tend to migrate less and cause less pain with dialysate infusion. Because of their configuration, bent catheters are associated with fewer occurrences of cuff extrusion and leaks. Peritoneoscopic and laparoscopic techniques of catheter insertion are well described and are associated with decreased rates of site infections, leaks and prolonged catheter survival. The internal cuff is placed in the musculature of the abdomen and the external cuff in the subcutaneous tissue. The catheter should exit facing downward and laterally and the exit site should not be placed near the midline, belt line or near any prior scars. For children with ostomies, fecal incontinence or obesity, the presternal exit site is preferred. Bicarbonate and acetate are rarely used as they commonly produce calcium precipitation and changes in the structure of the peritoneum, respectively. Dialysis is usually started 2 weeks after catheter placement to allow for adequate healing, incorporation of the cuffs and avoid leaks. For children with no other access, low volume dialysis in the supine position may be started in the first 24 hours without a significant risk of leak or subsequent infection and survival of the catheter. Exchange volume the exchange or “fill” volume is approximately 600-800 mL/m2 in children <2 years and 100-1200 mL/m2 in children >2 years old. With this technique, one empty bag is used to drain the peritoneal cavity and the other contains the dialysate solution (1. Both Gramnegative and Gram-positive organisms are responsible for the majority of episodes of peritonitis. Typically, vancomycin and a third generation cephalosporin are the antibiotics of choice. Catheter site infections are prevented with appropriate handling of the catheter and the use of local mupirocin in some series. Bleeding due to erosion of mesenteric vessels by the catheter is rare complication.

J Pediatr 2006; 148:770-778 213 Chapter 11 Transfusion and Anticoagulation Robert L. Introduction the oxygen carrying capacity of hemoglobin and its role in oxygen delivery is well understood. Transfusion of packed red blood cells has, therefore, become an important tool in the armamentarium of intensivists, and surgeons alike, in an attempt to reduce the oxygen debt associated with an underlying disease process. Currently no absolute value of hemoglobin concentration below which transfusion is mandated exists. There are multiple physiologic variables that dictate the necessity of transfusion. Defining this transfusion level has been the centerpiece of most recent literature on transfusion medicine. The impetus for these studies was the complication profile seen after transfusions including transmission of infectious disease, fluid overload and acute lung injury seen in patients post-transfusion. The underlying immunosuppression seen in many of our pediatric patients due to malignancy or 214 prematurity may complicate therapy with an increased risk of graft-versus-host disease in this population. This study showed a decreased in-hospital mortality rate and no difference in 30-day mortality in critically ill patients who had a more restrictive transfusion threshold (7g/dL). Guidelines, therefore, have been proposed and instituted at many centers to standardize transfusion medicine. These guidelines vary from institution to institution and rely upon critical review of the current literature as well as local transfusion policies and expert opinion. Neonatal Transfusion Premature infants are among the most commonly transfused patients in the hospital setting. Nearly 50% of infants will receive their first blood transfusion within two weeks after birth, and almost 80% of infants will receive at least one blood transfusion during their hospital stay [2,6]. Anemia in the preterm infant is most commonly due to either acute blood loss from multiple laboratory draws or due to inadequate marrow production – anemia of prematurity. Defining which patients will benefit from transfusion of blood components is difficult as the 216 symptoms of poor oxygen delivery or increased oxygen demand are vague and nondescript consisting of poor weight gain, tachycardia, apnea, persistent oxygen requirement or prolonged mechanical ventilation and lactic acidosis. Common practice in the 1970’s and 1980’s were to maintain a hematocrit of 40% in premature infants . A trend towards more restrictive policies has been seen over the last several decades. Additionally, more severe consequences of transfusion of packed red blood cells have been described including the development of bronchopulmonary dysplasia [7,8], retinopathy of prematurity  and necrotizing enterocolitis . It is felt that these outcomes may be due to the inflammatory modulators that are found from presence of leukocytes in non-irradiated red blood cells. There was no difference in the associated mortality, presence of retinopathy of prematurity or bronchopulmonary dysplasia between the two groups. Additionally, there was no statistically significant difference in the rates of intracranial hemorrhage or brain injury (18. This study supported previous thoughts that a high transfusion threshold subjects the infant to more risks of transfusion but does not confer any physiologic benefits. None of these guidelines have been compared in a prospective trial and many rely upon clinical expertise. Recombinant erythropoietin has been used to stimulate marrow and reduce the need for transfusion of autologous blood cells. One study showed a statistically significant reduction in number and volume of transfusions in preterm infants treated with erythropoietin. Additionally reticulocyte counts were higher with a higher hematocrit value at the end of the study in treated patients . Erythropoietin appears to be a safe and important part of a conservative transfusion practice in neonates. Only the latter of these were concerning for increased oxygen demand and oxygen debt that would be treated by increasing the hemoglobin level . Bateman et al, looked prospectively at 977 children admitted to an intensive care unit.
Facilities for surgeon’s hand-washing skin care pakistan buy bactroban 5gm on line, and the wearing of sterile gloves are essential acne hairline cheap bactroban online mastercard. A table skin care malaysia order bactroban in india, couch or reclining chair which allows the patient to skincare for over 60 cheap 5 gm bactroban overnight delivery lie supine is necessary acne treatment reviews generic bactroban 5 gm amex. The room size should be such as to allow enough space on either side of the table to facilitate the movement of the surgeon and the surgical trolley. Minimum Equipment requirement Sterile eyelid speculum, sterile cotton buds, sterile ophthalmic drape, sterile calipers (millimetre gauge), povidone 5% solution (aqueous based)/iodine wash, syringe (drug may be pre-loaded), drawing up needle, 30 gauge injection needle (a wider needle bore to be used with triamcinolone to prevent crystals jamming during injection), topical anaesthetic. Anaesthetic Topical anaesthesia will suffice in most cases especially when instilled copiously over 5-10minutes prior to injection. Supplementary sub-conjunctival or sub-tenon 1%2% lignocaine injection can be given if necessary. Patient preparation On the day of intra-vitreal injection, visual acuity and intra-ocular pressure check are not necessary if a two-stop approach to treatment is carried out. Application of a single use mydriatic to achieve pupillary dilatation is recommended. Check the patient can count fingers immediately after the injection to ensure the retinal artery is perfused. Eye Preparation Topical anaesthesia, followed by Povidone 5% aqueous solution (or equivalent) applied to eyelids, eyelid margins and into the conjunctival sac with a contact 77 time of 60 seconds, is a minimal requirement. Pre-injection broad spectrum topical antibiotics may be used in addition to the minimal requirements at the discretion of the treating clinician (359). Technique: Patient preparation Eye preparation Drape patient Insert eyelid speculum, ensure it is well positioned with eyelid margins and eyelashes are away from the site of injection Iodine solution Instruct the patient to direct gaze away from the injection site Mark the injection site using the calipers (avoid the horizontal meridians of the globe): aphakic/pseudo-phakic patients 3. A sterile cotton-tipped applicator placed at the site of penetration is also helpful in preventing reflux Check the patient can count fingers or can see hand movements to ensure central retinal artery is perfused. If patient cannot perceive light and eye is hard on digital palpation: 78 Check central retinal artery appearance. If pressure remains high with vision of no light perception consider anterior chamber paracentesis. Consideration should be given to checking the intraocular pressure following intravitreal injection of triamcinolone as it is known to be significantly associated with an intraocular pressure rise. Routine post-injection antibiotics are not recommended as there is no evidence that their use reduces the incidence of endophthalmitis (360), but can be used at the discretion of the treating clinician. Patients should be given clear instructions what to expect and a telephone number to contact for advice in the event of problem. Clinic review 4-8 weeks post-injection should be arranged depending upon therapeutic agent. Fluorescein and indocyanine green angiography are necessary for diagnosis and may be required to revise diagnosis and when considering a change in treatment Below are the list of examinations: 1. The collection of quality of life data does not need to be undertaken routinely on patients receiving treatment for age related macular degeneration. Quality of life data collection will be necessary to estimate cost effectiveness of treatment. Quality of life data may need to be collected as part of commissioning arrangements for patients receiving treatment. The interval between two doses should not be shorter than 4 weeks normally for ranibizumab or 8 weeks for aflibercept. However, there are instances where the occasional patient with hyperactive 80 lesions may for a short time require more intensive therapy. It is expected that all patients will receive 3 loading doses of ranibizumab, or aflibercept unless there are particular contraindications. Criteria for Continuation of treatment After the three initial doses, ranibizumab should be continued at 4 weekly intervals, aflibercept at 8 weekly intervals and pegaptanib at 6 weekly intervals if: a) There is persistent evidence of lesion activity b) the lesion continues to respond to repeated treatment c) There are no contra-indications (see below) to continuing treatment. There is evidence of deterioration of the lesion morphology despite optimum treatment. There is no evidence of other ocular pathology requiring investigation or treatment 3. Further research is required into appropriate duration and optimal regimen in terms of frequency of injections. It still remains to be seen whether less frequent dosing of ranibizumab or aflibercept than that used in the pivotal trials will achieve the same visual benefit. Pegaptanib treatment will reduce the risk of moderate and severe visual loss but most patients will still lose some vision over 2 years. Patients should understand the risk associated with intravitreal injections and be instructed to report symptoms suggestive of endophthalmitis without delay. Where no progression is demonstrable, or vision is not threatened observation is advised. When recommending intraocular bevacizumab (Avastin) it is extremely important to inform patients that it is unlicensed for this indication and that it has not undergone the usual rigorous clinical trials and independent evaluation by regulatory authorities. Adequate follow-up information must also be maintained on these patients, and recorded appropriately. Fundus photography has limited value in assessing and monitoring the progression of atrophic areas. Instead of using focal laser, a large spot size lower power (diffuse) laser is currently under investigation. Using computers in tablet form with inbuilt ability to enhance contrast, change background and zoom for magnification rapidly can be helpful. It is intended to enlarge the retinal image of the central field (364), magnifiying objects whose image would otherwise fall sufficiently within the scotoma to prevent recognition. The magnification allows the object to be resolved at an eccentric fixation point. After two years follow-up there were no cases of retinal detachment or visually significant posterior capsular thickening. For the 174 patients for who data was available at two years, a statistically significantly greater (p=0. These potential gains are reflected by an improvement in quality of life recorded at one year in study participants, and it is said to be costeffective by conventional standards (366). Implant technology is in evolution with new anterior and posterior segment implants under development, and further research is needed on their safety and efficacy. However there are several important caveats on their use, beginning with appropriate patient selection. Such devices may be a suitable option for some patients, bearing in mind the following pre-operative caveats. Clinical trials of novel therapies are now taking place but are not currently available in clinical practice. Patients report that after receiving news that their eye condition is not treatable, they tend not to hear further information during the consultation. It is therefore important that patients are given written information at the end of the consultation concerning their eye condition, available rehabilitation services and useful contact numbers. Patients with macular disease who have lesions which are not treatable with current therapies are often seen only once in the eye clinic and then discharged. They can be unaware of what to expect in the future or where they can obtain relevant information or how to find their way through the maze of services and 91 organisations. Although there may seem little advantage in seeing the patient a second time, because most are not able to take in information after receiving bad news, a follow up visit is of benefit to receive further information and ask questions. The clinic experience at time of diagnosis has an impact on the way patients deal with their diagnosis and visual impairment. A good initial experience at the hospital will almost certainly help the patient’s future outlook, expectations and achievements. Receiving a diagnosis without the follow up information leaves patients feeling lost and isolated. They should be given appropriate information about support services such as visual rehabilitation officers and low vision services. Patients appreciate being given information regarding their condition that can be read at leisure. It should be the responsibility of staff in the clinic to make information leaflets available and ensure that patients are offered them before leaving. The Macular Society and others have a wide range of materials in large print and audio. Empathetic handling of a new diagnosis for a patient is a responsibility for the whole unit; continuous staff training is needed. This means that when they are ready to seek further advice and information they have accurate information about their condition. A vague description such as ‘you have an eye condition to do with ageing’ is not acceptable. Vision prognosis – Provide clear information about the outlook for their vision: Will it develop in the second eye Patients must know how to obtain a new appointment urgently if they develop distortion or blurring in their second eye. Some professional advocate the use of Amsler grids for self-monitoring, while others advise patients to use any straight line in their environment. Either is acceptable as long as the patient understands the nature and need for regular self-monitoring for new symptoms, such as distortion, in their second eye. The lack of a current therapy does not mean that help in other forms is not available. Some awareness of the research in the area of retinal repair is helpful as many patients will wish to discuss the current research strategies; two examples are stem cells and electronic eye research. Patients should be told to contact the clinic if they have not received an appointment for treatment or further assessment within 2 weeks, also if there follow up appointment has been extended beyond 4-6 weeks. Many patients with macular degeneration suffer or will experience visual hallucinations. People see different images, from simple patterns of straight lines to detailed pictures of people or buildings. These can be disturbing, and may not be voluntarily mentioned by patients to friends, family or the medical profession as sufferers may be concerned that they might be developing a serious mental illness. The Macular Society is familiar with the condition and can talk to patients and provide a leaflet. Patients have no control over their age, genes or gender but they should be alerted to the other risk factors itemized below. All patients with macular degeneration/ dystrophy should be advised to stop smoking. Recent studies show that smoking reduces the protective effects of antioxidants in the eye and damages the structure of the eye. A diet rich in fruit and vegetables (sources of antioxidant vitamins), oily fish (source of omega-3 fatty acids) and sources of lutein/zeaxanthin (fruit and vegetables and eggs) is recommended. These measures are not proven conclusively to be beneficial and would not be expected to be harmful, and may be useful given what we know about the biology of the retina. With regard to nutritional supplements there are now many a vast number of different nutritional supplements for eye health available. Continuing ocular exams – why and how often the importance of ongoing regular eye examinations must be clearly explained to the patient, especially if they are likely to be discharged from the hospital system. Too often individuals never attend for any form of eye examination once diagnosis of a condition leading to sight loss has occurred, failing to understand that an eye examination is a good indicator of general health and provides an early warning for the development of other eye conditions.

The search was not confined to the population-based controlled trials or prospective studies in order to retrieve also the information about drug abuse and physical illness from other studies. Because the focus of the search and subsequent review of the literature was on humans, animal studies in connection with illegal substances abuse were not included in the search. A broad search strategy was conducted to ensure retrieval of all data about the physical illnesses of the 19 drugs selected. Finally, the experts engaged were asked to report unpublished data to the authors. PubMed literature search strategy Mesh terms used: ‘Diseases category/aetiology’ of ‘Diseases category/epidemiology’, ‘adverse effects’, ‘Comorbidity’, ‘Comorbid’. Textbooks in addiction medicine and internal medicine do not adequately review the physical morbidity associated with drugs of abuse. Nevertheless, the following seven textbooks were used as a source of physical health problems associated with drugs of abuse.

The then General Register Office prepared and 3 Introduction issued an updated version in 1950, and revisions to this were subsequently issued in 1956, (first revision), 1969 (second revision) and 1975 (third revision). It was revised in 1956 with the addition of 10 categories, and again in 1969 at which time the threecharacter categories were increased to 731. Some of these categories were subdivided (extended to four-character subcategories) so that the classification contained 1183 valid codes. The third revision, in 1975, further expanded the classification to 1426 valid codes. To identify and classify current surgical operations with particular reference to the incorporation of recent innovative techniques. To eliminate rarely performed operations but to include procedures not requiring the full operating theatre environment. To provide a flexible classification, responsive to less defined specialty boundaries and capable of future expansion. Both the Tabular List and Alphabetical Index were updated in January 1990 and the Alphabetical Index was again revised in April 1993. It was originally devised as an instrument to provide the best possible basis for accommodating current systems and future developments for data on surgical operations. As well as maintaining the planned objective, the fourth revision also incorporated two further general aspects. This was designed so anyone could submit their suggestions whenever it suited them.
