Non-tuberculous mycobacterial head and neck infections in children: Analysis of results and complications for various treatment modalities.

OBJECTIVES: Analyze the results and complications of various surgical interventions in a large cohort of children with non-tuberculous mycobacterial (NTM) head and neck infections and suggest a heuristic treatment protocol for managing this condition while aiming to maximize cure and minimize complications. METHODS: Retrospective chart review of 104 consecutive patients diagnosed with head and neck NTM at a tertiary paediatric hospital between January 1994 and December 2013 inclusive. RESULTS: 104 patients ranged in age between 8 months to 15 years (mean age 27 months) were reviewed and 97 patients were included in the final analysis. 6 patients excluded due to lack of follow-up and one excluded due to systemic immunocompromised condition. Sub-sites of NTM infections were submandibular (n=48, 46%), cervical (n=40, 38%), parotid (n=18, 17%) and submental (n=4, 4%). Some patients had more than one lesion so counted twice. Higher cure rates were demonstrated for primary excision (81%, p<0.01) versus incisional interventions (44%, p<0.01). Marginal mandibular nerve palsy following surgery was seen in 7 patients (7.2%). This was permanent in 4 patients (4%) and temporary in 3 patients (3%). All children who were complicated with marginal mandibular palsies had lesions in the submandibular region. The rate of palsy for submandibular disease alone was 15%, while 8% presented permanent palsy and 6% temporary. Marginal mandibular nerve palsy was more likely following excisional compared to incisional procedures (6 versus 1 patient, p<0.01). Hypertrophic scarring occurred in 7 patients: 3 patients following excision and 4 patients after an incisional procedure. One patient suffered long term spinal accessory nerve damage presented as winged scapula. CONCLUSIONS: Excision of NTM provides better cure rates compared to incision although at the expense of long term post-surgical morbidity. Excision should probably be the first line of treatment when the risk for neural damage is low. Incision and drainage with or without antimycobacterial treatment may be the preferred option for at-risk sub-sites (submandibular or parotid) in order to reduce long term morbidity.

Why patients miss follow-up appointments: a prospective control-matched study.

OBJECTIVES: To investigate missed appointments in a South African tertiary hospital. STUDY DESIGN: Prospective, descriptive series with controls. SETTING: The ENT/Oncology clinic at Tygerberg Academic Hospital, South Africa. SUBJECT: 305 patients with a head and neck malignancy who had follow-up appointments over 4 consecutive months between June and September 2006. A control group of 31 patients who attended the clinic was recruited in September 2006. METHOD: Analysis of the clinic attendance statistics to identify patients who missed follow-up appointments followed by a file review and interview of these patients. The results were compared with a control group. OUTCOME MEASURES: 1) Incidence rate of failure to attend follow-up. 2) Causative factors. RESULTS: 51 (17%) booked patients missed their appointments. Non-attenders were most likely to miss their follow-up between 6 and 12 months (17/31) after treatment. No correlations were found between diagnosis, disease stage and missed appointments. Reasons include: transport (19 responses), ill-health (6) and financial constraints (5). State transport was unavailable to almost two-thirds of the responders who cited transport as a problem. CONCLUSIONS: The 17% missed appointment rate is largely due to transport constraints. The commonest time for patients to miss appointments is the 6-12 month follow-up period. The authors seek to identify patients at risk of missed appointments and suggest interventions to decrease this incidence.

Kinetics of dengue virus-specific serum immunoglobulin classes and subclasses correlate with clinical outcome of infection.

The kinetics of dengue virus (DEN)-specific serum immunoglobulin classes (immunoglobulin M [IgM] and IgA) and subclasses (IgG1 to IgG4) were studied in patients suffering from dengue fever (DF), dengue hemorrhagic fever (DHF), and dengue shock syndrome (DSS). Serum samples from non-DEN febrile patients were included as controls. IgM, IgG1, and IgG3 serum antibodies were the predominant immunoglobulins throughout the course of illness in all three patient groups. In contrast, IgA antibodies were significantly higher in the acute phase in DSS patients compared to those in DF patients (P < 0.05). The levels of IgG1 differed significantly between patients with DF and those with DHF and DSS (P < 0.05). A significant difference was also found in IgG3 levels between DF patients and DHF patients (P < 0.05) but not between DF patients and DSS patients. Finally, levels of IgG4 antibodies differed significantly between DF patients and DSS patients (P < 0.05). Collectively, these data show that increased levels of DEN-specific IgA, IgG1, and IgG4 serum antibodies are risk markers for the development of DHF and DSS and that their measurement may provide valuable guidance for early therapeutic intervention.

[Low 5-year recurrence rate after surgical excision of 126 basal cell carcinomas with frozen section analysis upon indication]. / Laag 5-jaarsrecidiefpercentage na operatieve behandeling van 126 basalecelcarcinomen met vriescoupeonderzoek op indicatie.

OBJECTIVE: To determine the recurrence rate of basal cell carcinoma (BCC) after surgical excision. DESIGN: Retrospective. METHOD: The records of all 139 patients treated for BCC at the Department of Plastic Surgery and Hand Surgery, Leeuwarden Medical Centre, Leeuwarden, the Netherlands, in 1992 were reviewed. This was done by examining case histories and additional information was obtained from dermatologists, general practitioners, patients and the Dutch National Automated Pathological-Anatomical Archive. One hundred and twenty-six BCCs were investigated in 108 patients: 51 men and 57 women, with a mean age of 66 years (range: 24-92). Of these BCCs, 114 had not been previously treated and 12 were a relapse. Freeze section analysis was carried out during the excision if a sprouting or deep growth was suspected and if a tight excision or reconstruction with transposed or rotated piece was desired. RESULTS: The mean follow-up was 59 months (range: 5-86). Sixty-one BCCs on which frozen section analysis was performed were excised completely. In 65 BCCs which were excised without frozen section analysis, a second operation was necessary on 11 occasions to obtain histologically free margins. In both groups a tumour recurred on one occasion (2/126; 1.6%). CONCLUSION: Surgical treatment of BCC aimed at free histological margins, results in a recurrence rate of 1.6%.

Inflammatory mediators in dengue virus infection in children: interleukin-8 and its relationship to neutrophil degranulation.

The chemokine interleukin-8 (IL-8) has chemoattractant activity for neutrophils and is able to activate and degranulate these cells. We investigated whether IL-8 may exert these effects in children with dengue virus infection. Circulating levels of IL-8, neutrophilic elastase (a constituent of the azurophilic granula of neutrophils), and lactoferrin, released from specific granula, were measured in 186 children with dengue virus infection, 33 healthy children as negative controls and 11 children with bacterial infections as positive controls. Levels of IL-8 on admission were elevated in 71% of the dengue patients, while the elastase and lactoferrin levels were increased in 68 and 17% of patients, respectively. These levels were significantly higher than in healthy children (P < 0.05) for IL-8 and elastase but not for lactoferrin (by the Wilcoxon-Mann-Whitney [WMW] U test). Similar levels of IL-8 were found in patients with bacterial infections. Levels of IL-8 and elastase in patients with shock were significantly higher than in patients without shock (P = 0.02; WMW), but those of lactoferrin were not. IL-8 correlated with elastase and lactoferrin (r = 0.19 and P = 0.009 versus r = 0.24 and P = 0.001, respectively; two-tailed Spearman rank correlation). Thus, IL-8 levels are increased in most patients with dengue virus infection and correlate with degranulation of neutrophils as well as with some clinical and hemodynamic variables. These findings suggest a role for IL-8 in the pathogenesis of dengue virus infection.

Correlation between concentrations of melatonin in saliva and serum in patients with delayed sleep phase syndrome.

Exogenous melatonin, which can be used to treat certain circadian rhythm disorders, maximally advances delayed rhythms when administered 5 hours before the endogenous melatonin starts to increase. The time of the start of the endogenously melatonin is defined as Dim Light Melatonin Onset (DLMO). The DLMO concentration has been defined in serum to be 10 pg/ml. Because of the greater practicability of frequent saliva sampling over blood sampling, we have validated radioimmunoassay (RIA) measurements of melatonin in saliva in patients diagnosed as suffering from a typical circadian rhythm disorder: Delayed Sleep Phase Syndrome (DSPS). Based on these results we have defined the equivalent salivary DLMO concentration to be 4 pg/ml.

Psychological profile of patients suffering from Crohn's disease and ulcerative colitis.

Patients with Crohn's disease (CD, n = 61) and ulcerative colitis (UC, n = 24) were studied using an interview and a series of percept-genetic tests describing anxiety, defensive strategies, and the self-image. Attention was specifically directed at a subgroup of CD (n = 15) with its inflammation limited to the colon (colon Crohn, CC). There was also a control group (n = 43). CC had more immature parent relations than the other groups. They were more childishly concrete and more alexithymic. While CC differ from other Crohn patients in many respects, the real cleft opens up with regard to UC, in spite of location of their illness. CC patients obviously have a psychological profile of their own.
