The relationship between a history of selected medical conditions and risk of lymphomas was investigated in a hospital-based case-control study conducted in Northern Italy on 429 incident, histologically confirmed cases of non-Hodgkin's lymphoma (NHL), 158 cases of Hodgkin's disease (HD) and 1157 controls admitted to hospitals for acute conditions. The odds ratios (OR) for NHL were above unity in patients with a history of infectious mononucleosis (OR 2.9), herpes zoster (OR 1.8), pyelonephritis (OR 4.9), tuberculosis (OR 1.8), malaria (OR 1.9), any chronic bacterial diseases (OR 1.7), rheumatoid arthritis (OR 1.7) and psoriasis (OR 2.5). With reference to HD, the ORs were 4.0 for infectious mononucleosis, 2.9 for herpes zoster, 3.3 for pyelonephritis, 2.3 for tuberculosis, 1.4 for chronic bacterial diseases, 2.4 for rheumatoid arthritis, 2.7 for psoriasis and 2.1 for diabetes. The association of NHL and HD with herpes zoster was restricted to the first ten years since the onset of the disease. The relationships between NHL and mononucleosis (OR 12.9), malaria (OR 2.8) and psoriasis (OR 14.0) were stronger for cases aged > or = 60 years, and that with tuberculosis (OR 3.5) was stronger for younger cases. For HD, the positive association was stronger for cases aged > or = 40 years for herpes zoster (OR 3.8) and diabetes (OR 2.6). An increased risk of NHL was found in association with poliomyelitis (OR 1.6) (restricted to cases aged > or = 60 years, OR 4.0) and BCG immunizations (OR 1.6), but not with vaccination against smallpox, tetanus and diphtheria; increased risks of HD were found in relation to poliomyelitis and BCG immunization in cases aged > or = 40 years (OR respectively 2.5 and 2.1), or > or = 50 years (OR 4.3 and 2.2). Thus, our results confirm the association between a history of several chronic infectious and inflammatory diseases and the risk of NHL or HD, and are compatible with a role of chronic immunological alterations in the aetiology of lymphomas.

Diabetes is associated with many emergent ophthalmologic conditions. The management of patients with diabetes requires careful monitoring for visual symptoms and frequent physical examination for signs of retinopathy. Randomized studies have documented a significant reduction in the development of new retinopathy and the progression of existing retinopathy with tight control of diabetes. Photocoagulation laser therapy is helpful in preserving vision in severe nonproliferative retinopathy, for proliferative retinopathy, and for clinically significant macular edema. Vascular events include arterial and venous occlusions and cranial nerve palsies; important diagnostic clues are visual symptoms and the findings of ocular and neurologic examinations. Life-threatening infections associated with diabetes include endophthalmitis and mucormycosis, which require prompt diagnosis to prevent blindness or systemic infection. Herpes zoster infection, which is common in older patients and in patients with immunosuppression, may affect the trigeminal nerve and cause anterior uveitis and keratitis. Patients with zoster and skin vesicles on the face need emergent ophthalmologic evaluation and treatment because untreated ocular infection and inflammation may lead to scarring and synechiae formation in the anterior chamber, resulting in vision loss.

The identification of HHV-8 has opened the way for numerous epidemiological studies aimed at determining both the prevalence of HHV-8 in various sub-groups of the population (affected or not by KS) and at identifying possible cofactors necessary for the development of KS. We set up a study to evaluate the prevalence of HHV-8 in the South of Italy in KS cases, hospital patients and blood donors and to verify the role of immunosuppression in KS. In KS patients the prevalence of lytic and latent antigens were both 91% (29 positive cases). Lytic and latent antigens have prevalence rates of 20% and 15% respectively in hospital patients. In the donor group the rates were 16% for lytic antigens and 2% for latent antigens. The most recurrent chronic pathology in KS patients was cardiopathy (5 cases). The pathological case histories report 4 cases of Herpes Zoster, 6 of diabetes, one case of hepatitis C who had also had gonorrea. There was also a case, negative to HHV-8, who had had malaria after residing for three years in Oristano in Sardinia (a zone with high endemic malaria). Our study confirms that in Southern Italy there are relatively high prevalences of HHV-8 both in the general population and in blood donors and that immunodysregulation may be involved in the pathogenesis of KS. Other studies are necessary to confirm the sexual transmission of the HHV-8 virus and to better understand the natural history of HHV-8 infection.

Fifty women with breast cancer metastatic to bone or bone marrow involvement on light microscopy at the time of initial evaluation were treated with high-dose chemotherapy (HDC) and peripheral blood progenitor cell (PBPC) transplantation with CD34(+) cell selection using the Isolex 300i system. All patients received induction chemotherapy. PBPC were mobilized with chemotherapy and granulocyte colony-stimulating factor. The median CD34(+) progenitor purity was 94.7% (range 72-98.7%) and recovery 38.4% (range 21-60%). Forty-eight hours after HDC with cyclophosphamide, cisplatin and carmustine, PBPC were reinfused. Median time to neutrophil count >0.5 x 10(9)/l was 9 (range 9-12) days and to platelet transfusion independence 11 (4-30) days. These data demonstrate that selected CD34(+) PBPCs allow rapid hematologic reconstitution after HDC. During follow-up, 23% of patients developed herpes zoster. Two patients developed cytomegalovirus infections. Three patients developed fungal infections. The development of these infections was not associated with steroid use but appeared more frequently in patients with diabetes mellitus. Seventy-four per cent of patients received steroids for pulmonary toxicity. Treatment-related mortality was 4%. Progression-free survival and overall survival at 35 months was 22.4% and 40.5%, with a median of 11.4 months and 15.4 months, respectively.

An update on clinical aspects of HIV in africa highlights new proposed clinical definitions of adult AIDS and of tuberculosis in HIV+ adults, and staging of adult HIV infection. The 1986 WHO clinical definition of AIDS has been widely used in Africa, but now research suggests that this definition has several limitations: the definition will pick up several unrelated diseases such as diabetes mellitus and renal failure. It does not ascertain cases of AIDS marked by nonopportunistic infections. Most persons with pulmonary tuberculosis may be wrongly diagnosed with AIDS by this definition. The study showed that the WHO clinical definition has good specificity and positive predictive value for HIV+ people, but its positive predictive value fell to 30% in identifying people with AIDS in Africa. New definitions should take into account any serious morbidity, tuberculosis, neurological disease, both endemic localized Kaposi's, and aggressive typical Kaposi's sarcoma, and HIV serological testing. Tuberculosis is a problem because few HIV+ people suspected of having pulmonary TB (sputum-negative TB) actually have it based on bronchoscopy, while HIV+ persons with TB experience high mortality, often from pyogenic bacteremia. HIV+ persons with TB suffer high rates of relapse, possibly related to insufficient drug treatment or reinfection. 1 study showed that 6 months of isoniazid significantly improved incidence of TB over 30 months of follow-up. Staging of AIDS in Africa based on degree of immunosuppression was proposed as: 1) clinically inapparent HIV infection marked by pulmonary TB, soft tissue infections, and community acquired pneumonia; 2) lymphadenopathy, oral thrush, widespread pruritic maculopapular rash, herpes zoster, enteric illness, dysentery, and Kaposi's sarcoma; and 3) HIV wasting syndrome, chronic pulmonary disease, meningitis, and fever of unknown origin.

Cellulitis is a rare and severe soft-tissue infection characterized by acute, diffuse, spreading inflammation, often associated with systemic symptoms such as malaise and fever. Surgery of the head and neck, dental infections, sinusitis, upper respiratory tract infections, and trauma are the most common portal of entry for pathogens in facial cellulitis. A very unusual case complicating an ophthalmic herpes zoster in a 74-year-old woman was observed at the department of dermatology, Cagliari University (Italy). Culture of skin swabs showed growth of numerous Gram-negative bacilli, further identified as Pseudomonas aeruginosa. Therapy with intravenous ciprofloxacin was promptly instituted on the basis of the culture and sensitivity report. She was initially treated with daily drainage and twice-daily topical fusidic acid. The lesion completely resolved in 4 weeks, and no general complications or recurrence have been observed for 6 months. Early recognition and management of facial cellulitis is mandatory to avoid serious and generalized complications. Pseudomonas aeruginosa is rarely reported in facial cellulitis; there are apparently no reports of this infection occurring as a complication of ophthalmic herpes zoster. Herpetic damage of the anatomic barrier as well as impairment of defense mechanisms because of decompensated diabetes mellitus may have facilitated the colonization and proliferation of this opportunistic pathogen in our patient.

BACKGROUND: Herpes zoster oticus accounts for about 10% cases of facial palsy, which is usually unilateral and complete and full recovery occurs in only about 20% of untreated patients. Bilateral herpes zoster oticus can sometime occur in immunocompromised patients, though incidence is very rare. CASE PRESENTATION: Diabetic male, 57 year old presented to us with bilateral facial palsy due to herpes zoster oticus. Patient was having bilateral mild to moderate sensorineural hearing loss. Patient was treated with appropriate metabolic control, anti-inflammatory drugs and intravenous acyclovir. Due to uncontrolled diabetes, glucocorticoids were not used in this patient. Significant improvement in hearing status and facial nerve functions were seen in this patient. CONCLUSIONS: Herpes zoster causes severe infections in diabetic patients and can be a cause of bilateral facial palsy and bilateral Ramsay Hunt syndrome. Herpes zoster in diabetic patients should be treated with appropriate metabolic control, NSAIDS and intravenous acyclovir, which we feel should be started at the earliest. Glucocorticoids should be avoided in diabetic patients.

A retrospective study of 232 elderly patients seen between August 1998 and April 2000 at the skin clinic in Princess Haya hospital, Aqaba, was undertaken to determine the prevalence of skin disorders, and those most commonly associated with diabetes mellitus, in the elderly. Eczema/dermatitis was the commonest skin disorder seen (25.9% of cases), followed by pruritus without skin lesions (15.1%), viral infection (14.7%, most commonly herpes zoster), fungal infection (13.8%), and bacterial infection (10.3%). Bacterial infection was the commonest skin disorder in patients with diabetes mellitus (62.5%), followed by fungal infection (50.0%). Skin diseases cause considerable morbidity in elderly people; health promotion and education can do much to reduce the risks of these disorders in the elderly, especially those with diabetes.

The major causes of central diabetes insipidus are neoplastic or infiltrative lesions of the hypothalamus or pituitary, severe head injuries and pituitary or hypothalamic surgery. Central diabetes insipidus caused by viral infections has been rarely reported in immunosuppressed patients, such as those with acquired immunodeficiency syndrome or Cushing's syndrome. We report the case of a 48-year-old woman suffering from diffuse large cell lymphoma, who developed hypotonic polyuria, hypernatriaemia and somnolence after the first course of chemotherapy with CHOEP and rituximab. Diabetes insipidus was diagnosed by low urine osmolarity and an undetectable vasopressin concentration. MRI revealed no pituitary abnormalities but encephalitis, and lumbar punction confirmed herpes zoster infection. To the best of our knowledge this is the first description of central diabetes insipidus in a lymphoma patient caused by an opportunistic CNS-infection.
