With the widespread usage of acupuncture, the number of reports about complications of this treatment increases. Harmless disturbances are common and include minor bleedings or haematomas, pain during insertion or after withdrawal of the needle, and skin symptoms. In every second acupuncture treatment, at least one of these complications occurs. Orthostatic dysregulations are relatively rare and can be observed in only 1% of patients. They can be prevented by treating the patient in a lying position, especially in the first treatment session. Stab injuries of internal organs most often affect the lungs, resulting in a pneumothorax. At least 23 cases have been published, 2 of them with fatal consequences. An inquiry of Norwegian doctors even suggests that until 1995 in Norway alone 250 cases of pneumothorax after acupuncture occurred. Stab injuries of other internal organs or the CNS are only described in case reports, but some of them had fatal consequences. Stab injuries of peripheral nerves or large vessels and systemic bacterial infections like sepsis or endocarditis are very rare but serious consequences have been described. The transmission of viral infections due to insufficiently sterilised acupuncture needles loses more and more importance. The incidence of local infections can possibly be influenced, but even in Europe this complication still occurs frequently. The overview of published complications leads to the contraindications of acupuncture. Disturbances of coagulation, immune deficiency, abnormal heart valves or prosthetic valves are the most important ones to name. Suggestions for obtaining informed consent may be helpful while performing clinical trials.

The aim of the study was to investigate the mobilization of T cells in response to a stressful challenge (adrenalin stimulation), and to access T cells resided in the peripheral lymphoid organs in HIV infected patients. Seventeen patients and eight HIV seronegative controls received an adrenalin infusion for 1 h. Blood was sampled before, during and 1 h after adrenalin infusion. Proliferation and mean telomere restriction fragment length (telomeres) of blood mononuclear cells (BMNC) and purified CD8+ and CD4+ cells were investigated at all time points. In patients, the proliferation to pokeweed mitogens (PWM) was lower and decreased more during adrenalin infusion. After adrenalin infusion the proliferation to PWM was restored only in the controls. In all subjects telomeres in CD4+ cells declined during adrenalin infusion. Additionally, the patients had shortened telomeres in their CD8+ cells, and particularly HAART treated patients had shortened telomeres in all cell-subtypes. The finding that patients mobilized cells with an impaired proliferation to PWM during and after adrenalin infusion has possible clinical relevance for HIV infected patients during pathological stressful conditions, such as sepsis, surgery and burns. However, this study did not find a correlation between impaired proliferation and telomeres. It is concluded that physiological stress further aggravates the HIV-induced immune deficiency.

The pharmacotherapy of burn care has evolved from the first topical antibiotics instituted > 30 years ago. These have helped greatly to reduce the incidence of burn wound sepsis, but a better understanding of the principles of burn care has resulted in earlier burn wound excision and complete coverage with autograft, cadaver skin, synthetic dressings, and amnion. This has markedly reduced septic complications and ameliorated the hypermetabolic response to burn injury. The hypermetabolic response, which is mediated by hugely increased levels of circulating catecholamines, prostaglandins, glucagon and cortisol, causes profound skeletal muscle catabolism, immune deficiency, peripheral lipolysis, reduced bone mineralisation, reduced linear growth, and increased energy expenditure. Supportive therapy and pharmacological manipulation, acutely and during rehabilitation, with growth hormone, insulin and related proteins, oxandrolone and propranolol can ameliorate the hypermetabolic response, improving survival and long-term outcome. Despite judicious use of topical and systemic antibiotics, opportunistic nosocomial bacterial resistance threatens to annul the improved survival of patients with severe burns. Patterns of emerging resistance encountered in burn units need to be considered, in light of a decreasing antibiotic armamentarium. A holistic approach to pharmacotherapy of severely burned patients including current practice in antimicrobial control, analgesia, sedation, and anxiety management is required. Current therapy of frequently encountered problems, such as post-burn pruritus, prophylaxis of deep venous thrombosis and peptic ulceration, and pharmacological manipulation of inhalation injury in the burned patient is described. Current pharmacotherapy to ameliorate psychosocial problems associated with burns such as acute stress disorder, depression and post traumatic stress disorder are discussed. Better analgesics, newer antibiotics and immune stimulating drugs are required to reduce mortality and morbidity in large burns.

Substantial clinical and laboratory research has revealed that major injury causes abnormalities in both the innate and adaptive immune systems. However, the relative importance of each of these systems in the immune dysfunction after injury is poorly understood and difficult to establish by clinical studies alone. Rag1 (-/-) C57BL/6 mice (Rag1), which lack an adoptive immune system, and immune-sufficient wild-type (WT) C57BL/6 mice underwent 25% total body surface area burn injury or sham injury under anesthesia and were subjected to cecal ligation and puncture (CLP) at day 10 postinjury, a time of high CLP mortality in this model. To test the effect of adaptive immune deficiency on inflammatory cytokine production after injury, adaptive cell-depleted splenocytes from sham and burn WT and Rag1 mice were stimulated with LPS, and TNF-alpha and IL-6 production were assayed at days 1 and 7 postinjury. Intracellular expression of TNFalpha and IL-6 by F4/80 macrophages was also assessed on day 7 by intracellular cytokine staining. Finally, Rag1 animals were reconstituted with WT splenocytes, and the effect of such reconstitution on CLP survival and cytokine production was determined. Survival of sham WT animals after CLP was significantly higher (P < 0.01) than survival of burn WT and Rag1 sham and burn animals, all of which had equivalently low survival. Reconstitution of Rag1 animals with WT splenocytes restored CLP survival to WT sham levels. Splenocytes from Rag1 burn mice showed significantly augmented cytokine production when compared with WT burn mice on day 7 (P < 0.05). Reconstitution of Rag1 mice with WT splenocytes at the time of injury returned cytokine production to WT levels. Intracellular cytokine expression in F4/80 macrophages was increased to a similar degree after burn, but not sham burn injury in Rag1, reconstituted Rag1 and WT animals. These studies demonstrate that the adaptive immune system is necessary for protection from polymicrobial sepsis and plays a significant role in regulating the inflammatory response to injury.

Recent epidemiological surveys have demonstrated an important increase in nosocomial infections among which Candida sp. plays an increasingly prominent role. Candida is now involved in about 10% of all septicemia and leads to a very high mortality rate in immunodepressed patients. Clinical studies show that any modification of the host immune status can facilitate the proliferation of endogenous Candida which, according to the importance of the immune deficiency, can provoke diseases ranging from benign localized mucocutaneous candidosis to sometimes lethal systemic invasions. The pathogenic behavior of Candida cells is mainly due to a very high phenotypic biodiversity. Following even very slight environmental modifications, it may change its behavior through the appearance of new or amplified properties such as tube formation, adherence, protease secretion, etc. Together with the impairment of host defenses, these new invasive properties lead to the so-called opportunistic pathogenicity of Candida cells. From a host point of view, after the integrity of surface teguments, the mucosal protection is ensured by the Th1 "cellular" immune response which, through pro-inflammatory cytokine production, boosts the efficacy of the phagocytes (Polymorphonuclear cells and macrophages). Neutrophils are of particular importance as deep seated Candida proliferation is mostly associated with neutropenia. Whatever the pathogenic process, it is mostly due to modifications provoked by increasing medical awareness which makes patients more susceptible to illness. A better knowledge of the precise mechanisms involved and would lead to improved strategies for prevention.

Infections in immunosuppressed patients have always to be regarded as emergencies, as they have a high rate of complications and mortality. The most important risk factor is severity and duration of granulocytopenia. Risk scores help to identify patients who, despite their immune deficiency have a low risk of complications. Diagnostic measures to identify the causative microorganism and the source of infection is necessary. However, diagnostic investigation must not delay the immediate onset of antimicrobial treatment. Patients often have to be treated empirically as the identification of the causative microorganism or the source of infection are often unknown at the beginning of clinical symptoms. Empirical treatment has to be broad to cover possible microorganisms. Especially meningitis, abdominal infections, sepsis and pneumonia can be regarded as infectiological emergencies. Patients with these infections have to be treated with intensive antimicrobial treatment, taking into account the possible causative agents.

In this report, we describe a brother and sister who presented at birth with short-limb skeletal dysplasia, polyhydramnios, prematurity, and generalized edema. Dysmorphic features included broad nose, thick ears, thin lips, micrognathia, inverted nipples, ulnar deviation at the wrists, spatulate fingers, fifth finger camptodactyly, nail hypoplasia, and talipes equinovarus. Other features included short stature, microcephaly, psychomotor retardation, B-cell lymphopenic hypogammaglobulinemia, sensorineural deafness, retinal detachment and blindness, intestinal malrotation with poor gastrointestinal motility, persistent hyponatremia, intermittent hypoglycemia, and thrombocytopenia. Cardiac anomalies included PDA, VSD, hypertrophic cardiomyopathy, and arrhythmias. The brother had a small penis with hypospadias, hypoplastic scrotum, and non-palpable testes. Skeletal findings included absent ossification of cervical vertebral bodies, pubic bones, knee epiphyses, and tali. Both sibs died before age 2 years, one of overwhelming sepsis and the other of cardiorespiratory failure associated with her cardiomyopathy. Metabolic studies showed a type 1 pattern of abnormal serum transferrin glycosylation. Fibroblasts synthesized truncated LLOs, primarily Man(7)GlcNAc(2), suggestive of CDG-Ig. Both sibs were compound heterozygotes for a novel 301 G > A (G101R) mutation and a previously described 437 G > A (R146Q) mutation in ALG12. Congenital disorders of glycosylation should be considered for children with undiagnosed multi-system disease including neurodevelopmental delay, skeletal dysplasia, immune deficiency, male genital hypoplasia, and cardiomyopathy.

Primary thymic epithelial neoplasms (PTENs) are uncommon tumors of anterior mediastinum with a broad range of biological characteristics. We retrospectively reviewed 58 consecutive patients with a diagnosis of PTENs that were confirmed pathologically during 28 yr. There were 58 patients, 31 males (53.4%) and 27 females (46.6%), with a mean age of 43.6 +/-13.8 yr (range, 17-73 yr). Twenty-one (36.2%) patients presented at the Masaoka stage I, 13 (22.4%) patient at stage II, 18 (31.0%) patient at stage III, and 6 (10.4%) patients at stage IV. Forty-five (77.7%) patients had myasthenia gravis, 1 (1.7%) immune deficiency, 1 (1.7%) pancytopenia, and 1 (1.7%) nephrotic syndrome. No paraneoplastic syndrome was associated in 10 (17.2%) patients. Complete resection was accomplished in 41 (70.7%) patients, while incomplete resection was performed in 8 (13.8%) patients. In nine (15.5%) patients only biopsy was carried out. Radiotherapy was administered to 19 (32.8%) patients. Eleven (19.0%) out of 58 who presented at advanced stages (at least III) received chemotherapy. Median follow-up period was 59 mo (range, 1-278 mo). During the follow-up period, 17 deaths occurred. Five patients (29.4%) died of tumor-related causes, and the remaining 12 patients died of other causes (cardiovascular diseases [n = 1, 5.9%], sepsis [n = 4, 23.5%], and MG-related respiratory insufficiency [n = 7, 41.2%]). The overall survival rates at 5 yr and 10 yr were 63.9% and 54.2%, respectively. Tumor-related survival rates at 5 yr and 10 yr were 89.0% and 83.2%, respectively. In our series, disease stage, presence or absence of myasthenia gravis, and tumor size did not affect survival (p> 0.05), either. Complete resection of the tumor seems to be the best predictive factor for long-term survival.

Burn-induced immunosuppression not only increases susceptibility to infection, but also predisposes burn patients to related adverse sequelae, including systemic inflammatory response syndrome and sepsis. Although burn-related immunosuppression is not fully understood, it is characterized by decreased T- and B-lymphocyte function and by impaired functions of circulating leukocytes and complement. Alterations in defensins, a family of cationic, naturally occurring antimicrobial peptides, may underlie these immune deficiency patterns. Defensins are considered important components of the innate immune system, as they inhibit bacterial, fungal, and viral colonization. They also chemoattract immature dendritic cells and T lymphocytes, recruit neutrophils, macrophages, and monocytes, modulate complement and adjuvant activity, and promote inflammation and wound healing. Infectious states are associated with upregulation of circulating defensins, which suggests an underlying antimicrobial role. In addition, data from our laboratory demonstrated diminished levels of certain defensins in burned tissue. The inference is that decreased defensin levels in burn injury may facilitate infection and subsequent sepsis. It may also alter functions of T- and B-lymphocytes, neutrophils, macrophages, and complement, thereby contributing to the pathophysiology of burn-related systemic inflammatory responses. This article is a comprehensive review on the role of antimicrobial peptides in burns and wounds.

This report presents the case of a healed 5-month-old infant with necrotising (malignant) bilateral otitis externa from acute mastoiditis on the right side and sepsis caused by Pseudomonas aeruginosa infection. Despite of immediately performed mastoidectomy, targeted antibiotics and intensive local treatment, two third of both external auditory canal's epithelium had shown subcutaneous concentric necrosis and ejection which have been removed with repeated necretomies. After the remission of inflammatory symptoms, successful bilateral auditory canal reconstructions were performed. The observed right peripheral facial paresis at the beginning of disease remained stationary. The patient healed with residual symptoms after 2 months of treatment. Neither immune deficiency, nor diabetes could have been proven.
