First-ever HSV-1 recurrence following superficial facial chemical peel after 30-year latency following neonatal primary infection.

Recurrence of orofacial herpes simplex infection is a well-known potential complication of chemical peeling procedures. Risk of reactivation is believed to correlate with depth of peel, leading to the recommendation that all patients with history of primary orofacial herpes simplex infection or recurrent herpes labialis receive prophylactic antivirals prior to and after undergoing medium and deep peels. The following is a case of herpes labialis following a very superficial peeling procedure in an otherwise healthy 30-year-old male after primary infection as a neonate with no history of herpes simplex recurrence in the intervening 30 years. This case highlights the importance of history-taking and consideration of prophylactic antivirals in peels of all depths in patients with any history of primary infection, regardless of length of disease free period.

Herpes Simplex Reactivation After Surgical Treatment of Trigeminal Neuralgia: A Retrospective Cohort Study.

BACKGROUND: Herpes simplex virus (HSV) reactivation after surgery for trigeminal neuralgia has long been recognized. Only a few studies to date have focused on this complication, and its actual incidence remains unknown. The aim of this study was to investigate the incidence of postoperative herpes labialis (HL) in a cohort of patients treated with either percutaneous balloon compression or microvascular decompression to identify potentially significant differences between different treatments. METHODS: A total of 92 patients who were operated on for TN with microvascular decompression (group A) or percutaneous balloon compression (group B) in the period 2010-2017 were retrospectively evaluated. The 2 subgroups of patients were compared according to history of previous HL and incidence of postoperative HL. RESULTS: The final cohort comprised 56 male and 36 female patients. Average age was 58.50 years; 30 male patients belonged to group A and 26 male patients belonged to group B. Lifetime incidence of episodes of HL before surgery in 18/58 patients in group A (31.0%) and 12/34 patients in group B (35.3%), with no statistically significant difference among subgroups. Postoperatively, 1/56 patients in group A (1.7%) experienced HL compared 5/34 patients in group B (14.7%), with a strongly statistically significant difference between the 2 subgroups. CONCLUSIONS: In our clinical experience, herpes simplex virus reactivation after surgery for trigeminal neuralgia is not so rare and is still not completely understood. Postoperative herpes simplex virus reactivation could be due to a direct mechanical injury on gasserian ganglion neurons, which is more common after percutaneous balloon compression.

Long-term outcome of percutaneous balloon compression for trigeminal neuralgia patients elder than 80 years: A STROBE-compliant article.

This article evaluates the long-term outcome of percutaneous balloon compression (PBC) for trigeminal neuralgia (TN) patients elder than 80 years. A total of 138 elderly patients aged above 80 years with primary TN, who were admitted to Neurosurgery Department, Hangzhou First People's Hospital from January 2007 to December 2011 for PBC treatment, were retrospectively analyzed in this study. The postoperative cure rate of immediate pain was 98.6% (Barrow Neurological Institute [BNI] classes I, II); according to the follow-up, the pain cure rates at 1, 2, 3, 4, and 5 years after surgery were 93.5%, 90.4%, 84.7%, 80.4%, and 72.9%, respectively. In our group, postoperative diplopia was reported in 1 case, masticatory muscle weakness in 3 cases, and herpes labialis in 19 cases. A total of 100% of pain-cured patients exhibited facial numbness and facial hypoesthesia. No serious complications occurred in this group of patients. PBC is an effective and safe procedure for TN treatment and can be employed as the preferred regimen for elderly TN patients aged above 80 years in poorer physical condition.

Psychologic factors in the development of facial dermatoses.

In medical literature, as well as in daily practice, some common facial dermatoses are considered to be influenced or triggered by emotional factors. The main damager is stress, but depression and anxiety may play a role, among other factors. Some patients may experience a vicious cycle: Their facial dermatosis is triggered or worsened by stress, and in turn, the exacerbation itself is a major stressogenic stimulus. It appears that clinical wisdom and experience preceded clinical investigation in this field. Although patients testify that their emotional state may sometimes influence their facial condition, only limited experimental data exist so far, and only a few facial dermatoses were investigated.

Facial filler and neurotoxin complications.

Botulinum neuromodulators and injectable dermal fillers have become part of the armamentarium in the treatment of facial aging. Their successful use requires a fundamental knowledge of anatomy and physiology and a sound understanding of their risks and complications. Although neuromodulators and fillers continue to demonstrate a strong record of safety, several notable risks exist.

Clinical manifestation of selective IgA deficiency evidence after anti-TNF-α treatment in a psoriatic arthritis patient: case report.

It is known that the use of anti-TNF-α drugs is related to an increased incidence of infective diseases. This therapy can not be administered to patients having active infections and it has to be considered with caution in case of acquired or congenital immunodeficiency diseases. We report the case of a 28-years-old man affected by psoriatic arthritis; he developed some infections during treatment with TNF-α blockers. The infections were caused by a selective IgA deficiency, that was not evident before the anti-TNF-α blockers administration and disappeared after withdrawing the biological therapy. This case-report draws our attention to the possibility of cases of subclinical immunodeficiency, unknown by the patients, but important in the prognosis and in the therapeutic approach to these diseases. Therefore, it is important to evaluate carefully the immunologic status of patients during the pre-therapeutic screening for TNF-α blocking therapy.

Recurrent infections in children with nickel allergic contact dermatitis.

Some patients with nickel (Ni) allergic contact dermatitis (ACD) suffer from systemic symptoms after ingestion of Ni-rich foods, a condition termed Systemic Nickel Allergy Syndrome (SNAS). The aim of this study is to investigate in children the relationship between Ni ACD and lymphocyte subsets or susceptibility to infections. Nineteen children with Ni ACD and 18 controls matched for sex and age were enrolled. All participants underwent patch test, skin prick test and clinical assessment. Serum immunoglobulins and flow cytometry for lymphocyte subset study were also evaluated. In children with Ni ACD a higher incidence of recurrent upper respiratory tract infections and recurrent otitis media were detected. Serum levels of immunoglobulins and lymphocyte subsets did not show significant changes (p>0.05) between the two groups studied. We can hypothesize that in children with Ni ACD the risk of recurrent infections is increased. Although the clinical manifestations of SNAS are still controversial, we can suppose that recurrent infections may be considered a clinical symptom of this syndrome.

Iron metabolism markers and haptoglobin phenotypes in susceptibility to HSV-1 or/and HSV-2 lesion relapses.

Different haptoglobin (Hp) phenotypes play a role in several pathologic processes including infectious diseases. In order to evaluate the role of iron storage and metabolism in susceptibility to herpetic manifestations, we studied the frequency of the Hp phenotypes and iron metabolism in patients affected by H. Simplex virus 1 or 2 (HSV-1 or HSV-2), compared with controls. Hp phenotype and iron metabolism were determined in 100 patients with recurrent HSV-1 or HSV-2 manifestations during the relapses, and in 110 healthy subjects. The frequencies of the three Hp phenotypes in the patient group compared to the control group were 18% versus 14.5% p = NS for Hp 1.1, 25% versus 40% p = 0.03 for Hp 2.2 and 57% versus 45.5% p = NS for Hp 2.1. All iron metabolism parameters tested showed significant differences between patients and controls; haemoglobin (Hb), ferritin, and serum iron were lower, while transferrin was higher in the patients than in controls. Reductions in iron availability may be a risk factor for relapsing lesions of HSV-1 or HSV-2. Hp 2.2 phenotype may offer some protection against the recurrence of Herpes labialis or genitalis manifestations.

Systemic Inflammatory Response Syndrome and postoperative complications after orthognathic surgery.

Symptoms of Systemic Inflammatory Response Syndrome (SIRS) presenting immediately after surgery have lately been regarded as potential warnings of impending postoperative complications and multiple organ failure. Reports discussing the relationship between operative stress and SIRS are found in the field of digestive surgery, but not in that of oral surgery. Sixty-five patients with jaw deformity who had undergone maxillary and mandibular orthognathic surgery (Le Fort I osteotomy and sagittal splitting ramus osteotomy) between September 2003 and October 2006 were involved in this study. A search based on the SIRS diagnostic criteria resulted in assignment of 33 cases to the SIRS group and 32 cases to the non-SIRS group. Postoperative complications occurred in 27.3% of the SIRS group and 0.0% of the non-SIRS group (p<0.01). In four cases, a postoperative fluctuation in IL-6 level evaluated. These results suggest the importance of careful management of postoperative SIRS patients in preventing complications.

Comparison between full-mouth scaling and root planing and quadrant-wise basic therapy of aggressive periodontitis: 6-month clinical results.

BACKGROUND: The aim of this study was to test the hypothesis that there are no differences in clinical parameters in generalized aggressive periodontitis patients after full-mouth scaling and root planing (FRP) or quadrant-wise basic periodontal therapy (BPT) when combined with an antibiotic regimen. METHODS: Patients were allocated randomly to BPT (N = 15; mean age: 29.5 +/- 5.7 years) or FRP (N = 15; mean age: 28.4 +/- 5.7 years). All subjects received oral hygiene instructions including the use of a 0.12% chlorhexidine mouthrinse solution twice a day for 2 months. Patients also received amoxicillin, 500 mg, and metronidazole, 250 mg, three times a day for 7 days. Probing depth (PD), clinical attachment level, visible plaque, and bleeding on probing were recorded at baseline and at 2, 4, and 6 months post-therapy. Statistically significant changes within and between groups were determined using the general linear model repeated measures procedure. RESULTS: Both groups showed a significant improvement in all clinical parameters post-therapy, which was particularly evident at 2 months in the sites that had been deepest at baseline. For instance, the mean PD at sites with mean PD > or =7 mm at baseline had decreased 3.9 mm in the BPT group and 3.6 mm in the FRP group. At 6 months, the percentage of sites with PD > or =7 mm decreased from 13.2% +/- 3.2% to 0% in the BPT group and from 13.3% +/- 3.5% to 0.2% +/- 0.1% in the FRP group. No statistically significant differences were observed between groups for most clinical parameters. CONCLUSION: Within the limits of the present investigation, FRP and BPT caused comparable clinical effects in aggressive periodontitis patients when an adjunctive combined antibiotic regimen was included.

A practical UV source to induce Herpes simplex labialis lesions in the clinic.

BACKGROUND: Ultraviolet (UV) sources have been used to clinically induce herpes simplex lesions in the lips of susceptible individuals. METHODS: This study reports the optimization of a UV source for studies involving multiple clinical laboratory sites and subsequent clinical UV induction of cold sore lesions. We describe novel adaptations of a commercially available broadband UV phototherapy lamp that facilitate determination of individual's minimal erythemal dose (MED) and expose the lips with minimal risk of viral transmission to or between the volunteers and technicians. CLINICAL RESULTS: The source performed well in a clinical setting, with 171 of 386 subjects (44%) developing lesions, an induction rate similar to spectrally similar UV sources. CONCLUSIONS: The advantages of consistent and reproducible exposure geometry, additional UV shielding and biological hygiene achieved by our method significantly enhance the execution of UV-induced herpes simplex labialis studies.

Recurrent herpes and post-traumatic stress disorder.

A 33-year-old male presented with recurrent outbreaks of perioral herpes of disfiguring nature that remained unresolved following therapy. The first perioral outbreak occurred following a road accident. The psychiatric interview conducted with the patient suggested post-traumatic stress disorder (PTSD) secondary to the accident. Venlafaxine 50 mg/day was initiated and led to resolution of the PTSD symptoms within 8 weeks. The patient did not experience any further herpes outbreaks for about 10 months. Control of stress disorders in recurrent herpes is discussed from a therapeutic perspective.

Major salivary gland agenesis in a young child: consequences for oral health.

BACKGROUND: Salivary gland agenesis is a rare condition. It can be associated with some equally rare syndromes so that diagnosis can be delayed. CASE REPORT: The authors describe a case report. A 3-year-old girl, presented with dry mouth, carious teeth, recurrent herpes labialis and tonsillitis to Newcastle Dental Hospital. This case highlights the diagnostic and therapeutic challenges posed by 'salivary gland agenesis'. CONCLUSION: Primary and secondary paediatric healthcare professionals should be aware of the possibility of salivary gland agenesis in the setting of the 'non drooling baby'. Early detection of 'salivary gland agenesis' would do much to prevent the deleterious oral affects which follow the absence of salivary protection in the oral cavity.
