    Full Text Available Monilethrix is a rare autosomal dominant inheritable hair shaft defect with variable penetrance. The diagnosis is confirmed by the characteristic beaded appearance of the hair under light microscopy which occurs due to defective keratinization. We hereby describe a case of monilethrix syndrome with keratotic follicular papules, moniliform hair, and koilonychias in an 8-year-old Indian female child. A rare association of trichorrhexis nodosa was also noted in our case.

    To present a case series of 4 patients who underwent postoperative hair removal using the long-pulsed Alexandrite or Nd:YAG laser following intraoral cutaneous flap reconstruction. Patients underwent epilation in dermatology clinic with long-pulsed Alexandrite or Nd:YAG lasers, spaced 8 weeks apart, until hair removal was achieved. All patients achieved improvement in hair removal regardless of initial flap donor site with significant improvement in quality of life and minimal side effects. The long-pulsed Alexandrite and Nd:YAG represent safe and effective treatment options to improve patient quality of life following intraoral flap repair following excision of malignancy.

    Full Text Available Background: Finasteride acts by reducing dihydrotestosterone levels, thereby inhibiting miniaturization of hair follicles in patients with androgenetic alopecia (AGA. Oral finasteride is associated with side effects such as decreased libido, sexual dysfunction, and gynecomastia. Aim: The aim of the following study is to assess the efficacy of maintaining hair growth with 5% topical minoxidil fortified with 0.1% finasteride in patients with AGA after initial treatment with 5% topical minoxidil and oral finasteride for two years. Materials and Methods: A retrospective assessment was done in 50 male patients aged 20-40 years with AGA. All the patients had been initially treated with topical minoxidil and oral finasteride for a period of two years, after which the oral finasteride was replaced with topical minoxidil fortified with finasteride. Five of 50 patients had discontinued the treatment for a period of 8-12 months and were then resumed with only topical minoxidil fortified with finasteride. The patients′ case sheets and photographs were reviewed by independent observers and the efficacy of minoxidil-finasteride combination was assessed. Results: Of the 45 patients who underwent a continuous treatment for AGA, 84.44% maintained a good hair density with topical minoxidil-finasteride combinatio. Of the five patients who discontinued oral finasteride for 8-12 months, four demonstrated good improvement in hair density when treatment was resumed with topical minoxidil-finasteride combination. Conclusion: Topical finasteride can be considered for hair density maintenance after initial improvement with oral finasteride, thereby obviating the indefinite use of oral finasteride.

  6. Hair analysis as evidence in forensic cases.

    Because hair analysis can be used for the determination of drug use months after drug consumption, hair analysis data can often act as important and even decisive evidence in the courtroom. More recently developed GC/MS methods offer excellent sensitivity and can make the distinction between chronic heroin and codeine use, which was not possible earlier with radioimmunoassay techniques. From more than a thousand hair analyses, the morphine/codeine ratios necessary to determine heroin use were set at 5:1 for low morphine concentrations (< 1 ng/mg hair) and 2:1 for concentrations above 1 ng/mg hair. The distinction can be further focused with the additional analysis of the metabolite monoacetylmorphine (MAM). As can be seen from several case examples, hair analysis cannot pinpoint an exact date of opiate use, but it can be used to validate or invalidate a subject's statement concerning his/her drug consumption. Interpretations should always be made cautiously. Ranges, means and medians are also listed for amphetamine, cocaine and cannabis and work is under way to draw similar safety guidelines for these drugs.

    Full Text Available In this section, paraneoplastic entites of hair, nail, oral mucosa and pigmentation changes have been discussed. Some skin findings are “strong” indicator of a malignancy whereas others are not. Readers will encounter some “coincidental” or “common” entities as well as more “severe” changes for a paraneoplastic sign. In addition, it is crucial that some paraneoplastic lesions may predict for a recurrence of malignancy.

    Kinky hair syndrome is a sex-linked recessively inherited copper metabolic disorder with severe neuro degenerative change and infant death. In 1962, Menges and associates described five boys of a related pedigree with severe psychomotor retardation, seizures and widespread cerebral and cerebellar degeneration. In 1969, Weissenberg and associates specified the radiological characterization of the syndrome. Symmetrical metaphyseal spurring and diaphyseal periosteal reaction of the long bones, anterior rib flaring, a malformed cerebral arterial system and subdural effusion. In 1972, Danks and associates found the disease to be associated with a defect of copper metabolism, confirmed by studies with labelled Cu. Authors experienced a case with characteristic clinical picture, and report cerebral and abdominal arteriographic changes and plain radiographic findings with brain CT, DSA and post-mortem angiography.

    Pele’s hair are long, thin strands of basaltic volcanic glass formed when small drops of magma are spun or drawn out by the wind or streams of volcanic gas into long hair-like strands. Named for Pele, the Hawaiian goddess of fire, they are basically found in Hawaiian eruption deposits. Pele’s hair is deep yellow or gold and is commonly found downwind from active vents concentrated in hollows or other low energy ‘traps’. In literature the origin of these thin strands of glass have been linked to fountains from Hawaiian eruptions. Beside the high fountaining, Pele’s hair are actually found in other environments. In this work we investigated in detail the dimensions, surface textures and the nature of Pele’s hair, from four typical environment of formation at Hawaiian volcanoes: high fountaining, weak explosive activity, lava ocean entry and a lava skylight. Samples has been characterized in terms of textural and morphological features, in thin section and under the SEM. Pele’s hair consists of long strands of gold sideromelane, showing variable length, from an half mm to tens of mm, often without surface vesicles and sometimes including Pele’s tears inside or at the end. They are often found incomplete, since they are easily broken on landing or even during transport. Their surfaces are mostly rough, with ‘ploughs’ of different sizes and large cavities. Vesicles are visible in the cross sections of Pele’s hair. There are two mostly size population of bubbles: one elongated and central and parallel to the axis of elongation and the other one smaller, and rounded and dispersed across the cross section of the fibers. Pele’s hair often shows, in thin section, a single inner elongate vesicle in the middle of the fragment linked to bubble coalescence phenomena, along the entire length of the hair. Samples from the four volcanic environments show different features in terms of their shape, surface textures and micro-textures, pointing out that

    Full Text Available Transplantation of body hair in to scalp has been suggested as an option to treat extensive cases of baldness with poor donor scalp. However, evidence about its long-term efficacy is yet lacking, with very few published reports and the routine use of the technique is still controversial. We report the satisfactory outcome in a case of extensive baldness in whom hairs from different donor areas such as chest, abdomen, arms, thighs were transplanted on to scalp.

    2017-05-01

    During the First World War, anthrax cases in the United States and England increased greatly and seemed to be associated with use of new shaving brushes. Further investigation revealed that the source material and origin of shaving brushes had changed during the war. Cheap brushes of imported horsehair were being made to look like the preferred badger-hair brushes. Unfortunately, some of these brushes were not effectively disinfected and brought with them a nasty stowaway: Bacillus anthracis. A review of outbreak summaries, surveillance data, and case reports indicated that these cases originated from the use of ineffectively disinfected animal-hair shaving brushes. This historical information is relevant to current public health practice because renewed interest in vintage and animal-hair shaving brushes has been seen in popular culture. This information should help healthcare providers and public health officials answer questions on this topic.

    Digit hair tourniquets are relatively uncommon. There are reports in the literature of hair tourniquets involving other appendages, such as the penis and uvula, however the phenomenon is not widely recognised and is often overlooked by healthcare professionals. This article discusses two case studies in which hair was responsible for creating a tourniquet around a digit. The article explores possible causes and management options for patients, with reference to the case studies.

  15. Strong relationship between oral dose and tenofovir hair levels in a randomized trial: hair as a potential adherence measure for pre-exposure prophylaxis (PrEP.

    Directory of Open Access Journals (Sweden)

    Albert Y Liu

    Full Text Available Pre-exposure prophylaxis (PrEP trials using tenofovir-based regimens have demonstrated that high levels of adherence are required to evaluate efficacy; the incorporation of objective biomarkers of adherence in trial design has been essential to interpretation, given the inaccuracy of self-report. Antiretroviral measurements in scalp hair have been useful as a marker of long-term exposure in the HIV treatment setting, and hair samples are relatively easy and inexpensive to collect, transport, and store for analysis. To evaluate the relationship between dose and tenofovir concentrations in hair, we examined the dose proportionality of tenofovir in hair in healthy, HIV-uninfected adults.A phase I, crossover pharmacokinetic study was performed in 24 HIV-negative adults receiving directly-observed oral tenofovir tablets administered 2, 4, and 7 doses/week for 6 weeks, with a ≥3-week break between periods. Small samples of hair were collected after each six-week period and analyzed for tenofovir concentrations. Geometric-mean-ratios compared levels between each pair of dosing conditions. Intensive plasma pharmacokinetic studies were performed during the daily-dosing period to calculate areas-under-the-time-concentration curves (AUCs.Over 90% of doses were observed per protocol. Median tenofovir concentrations in hair increased monotonically with dose. A log-linear relationship was seen between dose and hair levels, with an estimated 76% (95% CI 60-93% increase in hair level per 2-fold dose increase. Tenofovir plasma AUCs modestly predicted drug concentrations in hair.This study found a strong linear relationship between frequency of dosing and tenofovir levels in scalp hair. The analysis of quantitative drug levels in hair has the potential to improve adherence measurement in the PrEP field and may be helpful in determining exposure thresholds for protection and explaining failures in PrEP trials. Hair measures for adherence monitoring may also

    Pigmented oral lesions compose a large number of pathological entities, including exogenous pigmentat oral tattoos, such as amalgam and graphite tattoos. We report a rare case of a graphite tattoo on the palate of a 62-year-old patient with a history of pencil injury, compare it with amalgam tattoos, and determine the prevalence of oral tattoos in our Oral Pathology Service. We also compare the clinical and histological findings of grafite and amalgam tattoos. Oral tattoos affect women more frequently in the region of the alveolar ridge. Graphite tattoos occur in younger patients when compared with the amalgam type. Histologically, amalgam lesions represent impregnation of the reticular fibers of vessels and nerves with silver, whereas in cases of graphite tattoos, this impregnation is not observed, but it is common to observe a granulomatous inflammatory response, less evident in cases of amalgam tattoos. Both types of lesions require no treatment, but in some cases a biopsy may be done to rule out melanocytic lesions.

    Full Text Available Quan Q Dinh, Rodney SinclairDepartment of Dermatology, St Vincent’s Hospital, Fitzroy, Victoria, AustraliaAbstract: Fewer than 45% of women go through life with a full head of hair. Female pattern hair loss is the commonest cause of hair loss in women and prevalence increases with advancing age. Affected women may experience psychological distress and impaired social functioning. In most cases the diagnosis can be made clinically and the condition treated medically. While many women using oral antiandrogens and topical minoxidil will regrow some hair, early diagnosis and initiation of treatment is desirable as these treatments are more effective at arresting progression of hair loss than stimulating regrowth. Adjunctive nonpharmacological treatment modalities such as counseling, cosmetic camouflage and hair transplantation are important measures for some patients. The histology of female pattern hair loss is identical to that of male androgenetic alopecia. While the clinical pattern of the hair loss differs between men, the response to oral antiandrogens suggests that female pattern hair loss is an androgen dependant condition, at least in the majority of cases. Female pattern hair loss is a chronic progressive condition. All treatments need to be continued to maintain the effect. An initial therapeutic response often takes 12 or even 24 months. Given this delay, monitoring for treatment effect through clinical photography or standardized clinical severity scales is helpful.Keywords: female pattern hair loss, androgenetic alopecia

  20. A Case Report of Cushing's Disease Presenting as Hair Loss.

    2017-01-01

    Cushing's syndrome is a rare endocrine disorder that comprises a large group of signs and symptoms resulting from chronic exposure to excess corticosteroids. Most cases of Cushing's syndrome are due to increased adrenocorticotropic hormone production from a pituitary adenoma, which is referred to as Cushing's disease. Most of the signs and symptoms are nonspecific and common in the general population, making a diagnosis often challenging. However, several dermatological manifestations, such as fragile skin, easy bruising, and reddish purple striae, are more discriminatory. Because uncontrolled Cushing's syndrome of any etiology is associated with substantial morbidity, including increased cardiovascular disease and mortality, it is important to make an early diagnosis. Unfortunately, median delays of 2 years to diagnosis have been reported. We report a case of a woman who had multiple dermatological findings, including facial plethora, easy bruising, violaceous striae, hirsutism, and acne, the latter 2 signs reflecting androgen excess. Of interest, our patient presented with a chief complaint of hair loss, a common complaint in the general population that occurs with a greater frequency in patients with Cushing's disease and is attributed to androgenetic alopecia, but it is rarely the presenting symptom.

    Detection of drugs in a child may be the first objective finding that can be reported in cases of suspected child abuse. Hair and urine toxicology testing, when performed as part of the initial clinical evaluation for suspected child abuse or maltreatment, may serve to facilitate the identification of at-risk children. Furthermore, significant environmental exposure to a drug (considered by law to constitute child abuse in some states) may be identified by toxicology testing of unwashed hair specimens. In order to determine the clinical utility of hair and urine toxicology testing in this population we performed a retrospective chart review on all children for whom hair toxicology testing was ordered at our academic medical center between January 2004 and April 2014. The medical records of 616 children aged 0-17.5 years were reviewed for injury history, previous medication and illicit drug use by caregiver(s), urine drug screen result (if performed), hair toxicology result, medication list, and outcome of any child abuse evaluation. Hair toxicology testing was positive for at least one compound in 106 cases (17.2%), with unexplained drugs in 82 cases (13.3%). Of these, there were 48 cases in which multiple compounds (including combination of parent drugs and/or metabolites within the same drug class) were identified in the sample of one patient. The compounds most frequently identified in the hair of our study population included cocaine, benzoylecgonine, native (unmetabolized) tetrahydrocannabinol, and methamphetamine. There were 68 instances in which a parent drug was identified in the hair without any of its potential metabolites, suggesting environmental exposure. Among the 82 cases in which hair toxicology testing was positive for unexplained drugs, a change in clinical outcome was noted in 71 cases (86.5%). Urine drug screens (UDS) were performed in 457 of the 616 reviewed cases. Of these, over 95% of positive UDS results could be explained by iatrogenic drug

    The delay of hair regrowth of mice after irradiation was examined to investigate its possibility as a biological dosimeter in the cases of localized over exposure. Hairs on the dorsal skin of mice were shaved and irradiated with a 90 Sr/ 90 Y β-ray source in early anagen or midanagen stage of hair cycle. Skin doses were 0.5-10 Gy and 1-4 Gy, respectively. Hair regrowth was observed with a scaling loupe. Hair regrowth delay was dose dependent, fitting the linear-quadratic function and the linear function according to the stages of hair. Histological observations indicated that the hair matrix cells death was the main cause of hair regrowth delay in the midanagen stage. Dose estimation functions, derived from the dose-effect relationship curves, could be applied for the dosimetry of the skin over exposure. It could detect a dose over 1 Gy, and as early as a few days after the exposure. (author)

    Hair casts or pseudonits are circumferential concretions, which cover the hair shaft in such a way that, it could be easily removed. They are thin, cylindrical, and elongated in length. We present an unusual case of an 8-year-old girl presenting with hair casts. Occurrence of these is unusual, and they may have varied associations. This patient was suffering from developmental delay. It is commonly misdiagnosed as and very important to differentiate from pediculosis capitis.

    In cases of partial body over-exposure, the dose estimation is often impossible without considerable error. The dose-effect relationship on the delay of hair regrowth and reduction in hair length of mice after irradiation were examined to investigate the possibility of hair growth as a biological dosimeter. Hairs on the dorsum skin of mice were shaved. Shaved areas were irradiated with a Sr-90/Y-90 β-ray source in the early anagen or midanagen stage of the hair cycle. Skin doses were from 0.5 Gy to 10 Gy. The time of hair regrowth and the length of hair was examined with the scaling loupe. The delay of hair regrowth was dose dependent, fitting the L-Q function. Reduction in hair length was less dose dependent. These findings were supported by the histological observations of mitosis and pycnosis in hair matrix cells. Dose estimation functions were derived from the dose-effect relationship curves. Hair regrowth delay is thought to be a sensitive biological dosimeter which can be applied as early as a few days after over-exposure. (4 figs.)

    People with rare hypertrichosis syndromes became crowd-drawing money-making phenomena in many 19th century sideshow acts. These individuals have been referred to as dog-men, hair-men, and werewolves. In 1993, Baumister et al. described congenital hypertrichosis lanuginose or Ambras syndrome: a distinct form of congenital hypertrichosis characterized by excessive hair growth over the body and face associated with facial and occasional dental anomalies. Much is not known about this syndrome since fewer than 50 cases have been documented worldwide. In this case report, a nine year old girl presented with excessive hair growth throughout her body that was denser along her midline. Furthermore, her face displayed the typical dysmorphic features characteristic of Ambras syndrome: a round tip nose, thickened nasal cartilage, antiverted nares, prominent philtrum with deep groove, and a trapezoid mouth. Oral examination revealed normal oral mucosa with completely missing and unerupted decidious and permanent teeth. Panoramic radiographs confirmed unerupted deciduous teeth. Previous case reports have mentioned the presence of occasional dental anomalies such as retarded first and second dentition and absence of some teeth. However, this is the first reported case of Ambras syndrome presenting with complete anodontia. Prior cytogenetic studies performed on persons with Ambras syndrome have implicated a balanced pericentric inversion of chromosome 8. However, it is likely that dental anomalies are likely a result of a different genetic rearrangement. Further studies are needed to explore the cause of this rare phenotype of Ambras syndrome with complete unerupted dentition.

    White piedra of the hair is a rare superficial fungal infection caused by several Trichosporon spp. 1 It typically manifests as white to light brown hard nodules, firmly attached to frontal, occipital, and parietal scalp hair. 1-9 The incidence of white piedra varies from country to country, and men and women of all ages are affected. 1 In Latin America, children and women appear to be the most affected with white piedra of the hair. 1-9 Given the variability of causative agents and the paucity of literature, very little is known about the geographical distribution of white piedra of the hair in American continent countries to help understand its epidemiology and aid in its diagnosis and treatment. In this report, we describe a case of white piedra of the hair in a Peruvian woman. We also conducted a systematic literature review of all case reports of white piedra on the American continent, with a view to determining the geographical distribution of the condition and identifying Trichosporon spp. commonly associated with this infection.

    Psychotrichology is the science, which covers the psychosomatics applied to hair problems, i.e., body-psyche phenomena involving scalp and hair disorders. The approaches involving psychotricology are varied and may include psychiatric,[1] psychoanalytical,[23] and those involving knowledge related to analytical psychology.[4] An analysis from the analytical psychology point of view, a theory developed by the physician Carl Gustav Jung, favors a symbolic view to the disease, providing it attributions and meanings that go beyond those related to physical body signs and symptoms only. This paper aims to describe and analyze, under the analytical psychology view, three cases the psychic and clinical demonstrations of which relate to symbolic and historic aspects concerning life of patients as possibilities of cause and maintenance of hair problems. The first of them is related to an 8-year-old girl who witnessed a scene of physical aggression by her father against her mother and developed a case of total alopecia. The second case is related to a 43-year-old woman who developed self-inflicted scalp dermatitis due to severe anxiety; and at last, the case of a telogen effluvium in a 23-year-old woman who developed hyperprolactinemia after the death of her mother, having to substitute her in the care about her husband and brothers. Looking at the clinical history and symbolic matters of scalp and hair diseases enabled, in the aforementioned cases, a better understanding of patients' psychoemotional disorders that may be related to the beginning and maintenance of clinical cases presented by them.

    Pemphigus, defines a group of disorders in autoimmune etiology which could be life-threatening and clinical manifestations are mainly epithelial blistering affecting cutaneous and/or mucosal surfaces including oral mucosa. The aim of our study is to evaluate the clinical appearance of pemphigus with oral involvement by reported 15 pemphigus cases. This retrospective study of 15 cases of pemphigus obtained over a period of 7 years from 2006 to 2013 in Istanbul University, Dentistry Faculty, Oral Medicine and Surgery Department was designed. Age distribution of pemphigus was from 15 to 59 years with an average age of 41.3 years. Of the 15 patients, the male:female ratio was 1:2.75 (4 male, 11 female). The most common clinical various of pemphigus was pemphigus vulgaris, diagnosed in all patients. The buccal mucosa (34.3%) was the most commonly affected site followed by tongue (20%), gingiva (17.1%), palate (11.4%), lips (11.4%) and floor of mouth (5.7%). Our explanation of this conclusion, while speculative, is that socioeconomic situation related stress in males and hormonal changes like pregnancy and menostasis in females; systemic disease and using drugs; dental trauma and bruxism could be responsible for flare up in the disease.

    Both ablative and non-ablative fractional lasers have been applied to various uncommon hair disorders. The purpose of this study was to demonstrate the clinical effects of fractional laser therapy on the course of primary follicular and perifollicular pathologies and subsequent hair regrowth. A retrospective review of 17 patients with uncommon hair disorders - including ophiasis, autosomal recessive woolly hair/hypotrichosis, various secondary cicatricial alopecias, pubic hypotrichosis, frontal fibrosing alopecia, and perifolliculitis abscedens et suffodiens - was conducted. All patients had been treated with non-ablative and/or ablative fractional laser therapies. The mean clinical improvement score in these 17 patients was 2.2, while the mean patient satisfaction score was 2.5. Of the 17 subjects, 12 (70.6%) demonstrated a clinical response to non-ablative and/or ablative fractional laser treatments, including individuals with ophiasis, autosomal recessive woolly hair/hypotrichosis, secondary cicatricial alopecia (scleroderma and pressure-induced alopecia), frontal fibrosing alopecia, and perifolliculitis abscedens et suffodiens. Conversely, patients with long-standing ophiasis, surgical scar-induced secondary cicatricial alopecia, and pubic hypotrichosis did not respond to fractional laser therapy. Our findings demonstrate that the use of non-ablative and/or ablative fractional lasers promoted hair growth in certain cases of uncommon hair disorders without any remarkable side effects.

    Full Text Available Activities of traditional barbers are an age-long practice in northern Nigerian. They are involved in conducting hair barbing and uvulectomy of newborn babies usually on the 7 th day of life. This procedure is often associated with complications like bleeding, infections, but its association with clavicular fracture is a rare event which had not been reported before now. Therefore, the case of a 10-day-old Nigerian girl is highlighted. She was managed conservatively with minimal handling of the involved limb.

    2001-01-01

    This study was designed to detail the demographic and phenomenological features of adult chronic hair-pullers. Key possible subtypes were identified a priori. On the basis of the phenomenological data, differences between the following possible subtypes were investigated: hair-pullers with and without DSM-IV trichotillomania (TTM), oral habits, automatic versus focused hair-pulling, positive versus negative affective cues prior to hair-pulling, comorbid self-injurious habits, obsessive-compulsive disorder (OCD), and tics. Forty-seven participants were drawn from an outpatient population of chronic adult hair-pullers. A structured interview that focused on hair-pulling and associated behaviors was administered to participants. Six of the participants (12.8%) were male, and 41 (87.7%) were female. A large number of hair-pullers (63.8%) had comorbid self-injurious habits. A greater proportion of male hair-pullers had comorbid tics when compared with females. Certain subgroups of chronic hair-pullers (e.g., hairpullers with or without automatic/focused hair-pulling, comorbid self-injurious habits, and oral habits) were found to differ on a number of phenomenological and hair-pulling characteristics. However, differences between other possible subgroups (e.g., hair-pullers with or without DSM-IV TTM, comorbid OCD, and negative versus positive affective cues) may reflect greater severity in hair-pulling symptomatology rather than distinct subtypes of chronic hair-pulling. The findings of the present study also indicated that chronic hair-pulling (even in cases where DSM-IV criteria for TTM were not met) has a significant impact on quality of life. The present study provided limited support for the existence of possible subtypes of chronic hair-pulling. Recommendations are made for further investigations into such subtypes.

    Lichenoid drug reactions are more common in skin, but they may also occur in the oral mucosa. It is difficult to diagnose these lesions due to their clinical similarity to the idiopathic oral lichen planus lesions. The present article reports a case of lichenoid reaction in oral mucosa associated to the use of carbamazepine, emphasizing the diagnostic process.

    This article presents results from 1872 hair samples, which were analyzed for fatty acid ethyl esters (FAEEs) and ethyl glucuronide (EtG). The results were evaluated in the context of self-reported drinking behavior, the use of hair cosmetics, the gender of the sample donors and hair sample length. For comparison, CDT and GGT in serum were available in 477 and 454 cases, respectively. A number of alcohol abstainers or low moderate drinkers and excessive drinkers were selected for assessment of cut-offs for FAEEs in the proximal 6cm hair segments and for EtG in the proximal 3cm hair segments. Cut-off values were assessed by ROC analysis. It was found that the cut-offs of 1.0ng/mg FAEE and 30pg/mg EtG presently used for excessive drinking lead to a low portion of false positives (4% and 3% respectively) but to a higher portion of false negatives (23% and 25% respectively). Comparison of the mean and medium concentrations in samples without any reported hair cosmetics (N=1079) and in samples with reported use of hair spray (N=79) showed an increase by the factor of about two for FAEE but no significant difference for EtG. Mean values of EtG were decreased by 80% in bleached samples (N=164) and by 63% in dyed samples (N=96). There was no significant effect of bleaching and dyeing on FAEE. Hair gel and hair wax, oil or grease showed no significant effect on both FAEE and EtG. With respect to gender and investigated hair length ambiguous results were obtained because of major differences in the compared subpopulations of male with higher alcohol consumption and mainly shorter hair, and less drinking female with longer hair. For excessive drinkers FAEEs in the 0-6cm hair segment and EtG in the 0-3cm segment decreased with increasing time of reported abstinence before sample collection. These drinkers attain the level of teetotalers only after more than 10 months of abstinence. In comparison to scalp hair, FAEEs recovered from armpit hair and leg hair were lower and from

    Full Text Available The treatment of hair loss diseases is sometimes difficult because of insufficient efficacy and limited options. However, recent advances in understanding of the pathophysiology and development of new remedies have improved the treatment of refractory hair loss conditions. In this article, an update on the management of hair loss diseases is provided, especially focusing on recently reported therapeutic approaches for alopecia areata (AA. An accurate diagnosis is indispensable to optimize treatment. Dry dermoscopy represents new diagnostic techniques, which could enable the differentiation of barely indistinguishable alopecias, e.g. AA and trichotillomania. An organized scalp biopsy adopting both vertical and transverse sectioning approaches also provides a deep insight into the pathophysiology of ongoing alopecias. Among various treatments for AA, intraregional corticosteroid and contact immunotherapy have been recognized as first-line therapies. However, some AA cases are refractory to both treatments. Recent studies have demonstrated the efficacy of pulse corticosteroid therapy or the combination of oral psoralen ultraviolet A therapy and systemic corticosteroids for severe AA. Previous clinical observations have suggested the potential role of antihistamines as supportive medications for AA. Experimental evaluation using AA model mice further supports their effectiveness in AA treatment. Finasteride opens up new possibilities for the treatment of androgenetic alopecia. For androgenetic alopecia patients refractory to finasteride, the combination of finasteride with topical minoxidil or the administration of dutasteride, another 5 alpha-reductase inhibitor, may provide better outcomes. Scarring alopecia is the most difficult form of hair loss disorder to treat. The bulge stem cell area is destroyed by unnecessary immune reactions with resultant permanent loss of hair follicle structures in scarring alopecia. Currently, treatment options for

    2017-09-01

    Full Text Available Background: Lichen planus is a chronic muccocutaneous inflammatory disorder. Oral lichen planus (OLP has certain specific characteristics in its clinical presentation, but can also be presented in forms resembling other diseases. This may introduce difficulty in the diagnostic process. It has been reported that OLP affects between 0.1 to 4% individuals, predominantly women and people over 40 years old. Case Report: A 46-year-old woman complained of a non-healing ulcer present for 1.5 months. Intraorally, multiple white striae with prominent central areas of brownish hyperpigmentation were apparent on the right and left buccal mucosa, right and left buccal sulcus, and lateral and dorsum of the tongue. A biopsy was completed and the histopathology features confirmed the diagnosis of OLP. For the initial treatment, a topical corticosteroid was prescribed, followed by steroid mouthwash. Response to this treatment was positive. OLP has been frequently reported to affect women over the age of 40, with psychological stress as a primary predisposing factor. The clinical presentation is characteristic of Wickham’s striae with erosive areas. However, a biopsy and histopathological examination is mandatory to confirm the diagnosis. The clinical feature of pigmented OLP has been reported and confirmed by microscopic finding of band-like lymphocytic appearance which is the pathognomonic features of OLP, along with basal cell liquefaction degeneration, and melanin in continence at the lamina propria. Conclusion: Pigmented OLP is a variant of erosive OLP. Anamnesis, clinical presentation, and histopathological examination confirm diagnosis.

    To systemically search the literature for case reports concerning adverse effects associated with oral and peri-oral piercings on oral health and/or general health.   MEDLINE and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched up through 1 April 2010 to identify appropriate studies. Independent screening of the titles and abstracts identified 1169 papers from MEDLINE and 73 papers from CENTRAL. Subsequently, 67 papers describing 83 cases were processed for data extraction. The case reports described complications in oral and general health. In this review, 96 complications were described for 83 cases. Of the 96 reported complications, 81% (n=84) occurred in cases of tongue piercings, 20% (n=21) in cases of lip piercings and 1% (n=1) in cases of other oral piercings. In eight cases, subjects had two oral and/or peri-oral piercings. Gingival recession was the most frequently described complication. Periodontitis and gingival recession were seen at the central mandibular incisors. Tooth fracture is mostly reported in subjects with tongue piercings. Among the case reports, there were complications like normal post-operative swelling and localized inflammation but also more serious complication that may even have been life threatening. Also in the long term, piercing may be associated with gingival recession and tooth fracture. Therefore, oral and/or peri-oral piercings are not without risks. Patients considering a piercing should be made aware of this. Those patients wearing a piercing should be screened by a dental professional for possible complications on a regular basis. © 2011 John Wiley & Sons A/S.

    Full Text Available Albinism consists of a group of genetically inherited autosomal recessive conditions which are typically characterized by a congenital reduction or absence in melanin pigment biosynthesis which gives the natural color in the skin, iris of the eyes, and hair. A person with albinism may have one or many of the following symptoms: absence of color in the hair, skin, or iris of the eye, lighter than normal skin and hair, patchy, missing skin color, crossed eyes (strabismus, light sensitivity (photophobia, rapid eye movements (nystagmus, vision problems, or functional blindness, severe gingivitis, oral mucosal ulceration, and periodontal disease. A dentist can play a significant role in successfully treating albino patients if he/she has basic knowledge of the symptoms of albinism. We present a case report of a 14-year-old child suffering from oculocutaneous albinism who was reported to the Department of Periodontology, Himachal Pradesh Government Dental College and Hospital, Shimla, Himachal Pradesh, with a chief complaint of bleeding gums and oral malodor.

    Hair diseases represent a significant portion of cases seen by pediatric dermatologists although hair has always been a secondary aspect in pediatricians and dermatologists training, on the erroneous basis that there is not much information extractable from it. Dermatologists are in the enviable situation of being able to study many disorders with simple diagnostic techniques. The hair is easily accessible to examination but, paradoxically, this approach is often disregarded by non-dermatologist. This paper has been written on the purpose of trying to serve in the diagnostic process of daily practice, and trying to help, for example, to distinguish between certain acquired and some genetically determined hair diseases. We will focus on all the data that can be obtained from our patients' hair and try to help on using the messages given by hair for each patient. Quite often it is extremely hard to distinguish between abnormality and normality in neonatal hair aspects. We will specially focus in the most common physiological changes that may mislead to an incorrect diagnosis. Specific treatment for those hair diseases that do have one, and basic general approach to improve the cosmetic appearance of hair, will be also be discussed for those hair disturbances that do not have a specific treatment.

    Full Text Available Abstract Introduction Over the past two decades, the study of chronic cocaine and crack cocaine exposure in the pediatric population has been focused on the potential adverse effects, especially in the prenatal period and early childhood. Non-invasive biological matrices have become an essential tool for the assessment of a long-term history of drug of abuse exposure. Case report We analyze the significance of different biomarker values in hair after chronic crack exposure in a two-year-old Caucasian girl and her parents, who are self-reported crack smokers. The level of benzoylecgonine, the principal metabolite of cocaine, was determined in segmented hair samples (0 cm to 3 cm from the scalp, and > 3 cm from the scalp following washing to exclude external contamination. Benzoylecgonine was detectable in high concentrations in the child's hair, at 1.9 ng/mg and 7.04 ng/mg, respectively. Benzoylecgonine was also present in the maternal and paternal hair samples at 7.88 ng/mg and 6.39 ng/mg, and 13.06 ng/mg and 12.97 ng/mg, respectively. Conclusion Based on the data from this case and from previously published poisoning cases, as well as on the experience of our research group, we conclude that, using similar matrices for the study of chronic drug exposure, children present with a higher cocaine concentration in hair and they experience more serious deleterious acute effects, probably due to a different and slower cocaine metabolism. Consequently, children must be not exposed to secondhand crack smoke under any circumstance.

  16. A Case Report of Cushing’s Disease Presenting as Hair Loss

    Directory of Open Access Journals (Sweden)

    Emily G. Lefkowitz

    2017-02-01

    Full Text Available Cushing’s syndrome is a rare endocrine disorder that comprises a large group of signs and symptoms resulting from chronic exposure to excess corticosteroids. Most cases of Cushing’s syndrome are due to increased adrenocorticotropic hormone production from a pituitary adenoma, which is referred to as Cushing’s disease. Most of the signs and symptoms are nonspecific and common in the general population, making a diagnosis often challenging. However, several dermatological manifestations, such as fragile skin, easy bruising, and reddish purple striae, are more discriminatory. Because uncontrolled Cushing’s syndrome of any etiology is associated with substantial morbidity, including increased cardiovascular disease and mortality, it is important to make an early diagnosis. Unfortunately, median delays of 2 years to diagnosis have been reported. We report a case of a woman who had multiple dermatological findings, including facial plethora, easy bruising, violaceous striae, hirsutism, and acne, the latter 2 signs reflecting androgen excess. Of interest, our patient presented with a chief complaint of hair loss, a common complaint in the general population that occurs with a greater frequency in patients with Cushing’s disease and is attributed to androgenetic alopecia, but it is rarely the presenting symptom.

  17. Case Report Form for oral health assessments: methodological considerations

    Directory of Open Access Journals (Sweden)

    Joana Christina Carvalho

    2012-01-01

    Full Text Available Information on the oral health condition of the target population is required to enable the development of policy strategies for oral health promotion. This information needs to be substantiated by reliable data obtained through regular oral health assessments. Countries around the world have set up oral health data-registration systems that monitor the oral health of the population. These systems are either integrated in the public oral health care service or in national surveys conducted on a regular basis. This paper describes the conception and development of a Case Report Form for oral health assessments and introduces a recently developed electronic data-registration system for data capture in oral health surveys. The conception and development of a Case Report Form poses a number of challenges to be overcome. In addition to ensuring the scientific quality of its contents, several requirements need to be met. In the framework of national oral health surveys, handwritten data capture has proven accurate, but entails an important workload related to the printing and transporting of the forms, data transfer and storage of the forms, as well as the time required to perform these tasks. On the other hand, electronic data capture enables time saving and better performance. However, the advantages of this system may not be fully acknowledged by general practitioners, and their motivation to employ information and communication technologies may need to be encouraged. In the long term, the inclusion of electronic data registration in university training is probably the best strategy to achieve this.

    2015-08-01

    Noonan-like syndrome with loose anagen hair (NSLH), also known as Mazzanti syndrome, is a RASopathy characterized by craniofacial features resembling Noonan syndrome, cardiac defects, cognitive deficits and behavioral issues, reduced growth generally associated with GH deficit, darkly pigmented skin, and an unique combination of ectodermal anomalies. Virtually all cases of NSLH are caused by an invariant and functionally unique mutation in SHOC2 (c.4A>G, p.Ser2Gly). Here, we report on a child with molecularly confirmed NSLH who developed a neuroblastoma, first suspected at the age 3 months by abdominal ultrasound examination. Based on this finding, scanning of the SHOC2 coding sequence encompassing the c.4A>G change was performed on selected pediatric cohorts of malignancies documented to occur in RASopathies (i.e., neuroblastoma, brain tumors, rhabdomyosarcoma, acute lymphoblastic, and myeloid leukemia), but failed to identify a functionally relevant cancer-associated variant. While these results do not support a major role of somatic SHOC2 mutations in these pediatric cancers, this second instance of neuroblastoma in NSLAH suggests a possible predisposition to this malignancy in subjects heterozygous for the c.4A>G SHOC2 mutation. © 2015 Wiley Periodicals, Inc.

    We aimed to compare oral hygiene habits, orodental status, and dental procedures in patients with infective endocarditis (IE) according to whether the IE-causing microorganism originated in the oral cavity. We conducted an assessor-blinded case-control study in 6 French tertiary-care hospitals. Oral hygiene habits were recorded using a self-administered questionnaire. Orodental status was analyzed by trained dental practitioners blinded to the microorganism, using standardized clinical examination and dental panoramic tomography. History of dental procedures was obtained through patient and dentist interviews. Microorganisms were categorized as oral streptococci or nonoral pathogens using an expert-validated list kept confidential during the course of the study. Cases and controls had definite IE caused either by oral streptococci or nonoral pathogens, respectively. Participants were enrolled between May 2008 and January 2013. Cases (n = 73) were more likely than controls (n = 192) to be aged calculus, and infectious dental diseases did not significantly differ between groups. Patients with IE caused by oral streptococci differ from patients with IE caused by nonoral pathogens regarding background characteristics, oral hygiene habits, and recent dental procedures, but not current orodental status. © The Author 2017.

    INTRODUCTION: Hair loss is a common complaint seen in dermatology clinics. From frustration and attempts at self-help, patients with hair loss may present to the dermatologist with false beliefs, or myths, about the causes of their condition and what treatments are effective. METHODS: We identified 12 common myths about hair loss, categorized as myths about minoxidil treatment, vitamin and mineral supplements, natural topical treatments, and hair care practices. We performed a PubMed search to find evidence to support or refute each myth. RESULTS: We found that there is little evidence to support many of these common hair loss myths. In some cases, randomized controlled trials have investigated the effects of particular therapies and point to the effectiveness of certain hair loss treatments. DISCUSSION: In many cases, there have not been sufficient randomized controlled trials to evaluate the effect of different therapies and hair care practices on hair loss. It is best to guide patients toward treatments with a long track record of efficacy and away from those where little is known scientifically. J Drugs Dermatol. 2017;16(7):690-694..

    Oral submucous fibrosis is a disease that involves the oral mucosa and produces fibrous changes in several sites of the mouth. It could lead to severe oral deformities with inability to open the mouth, tongue depapillation, and sometimes horseness of voice. Clinical importance of the disease is due to two reasons, namely: (1) it is a disease that results from the use of betel-nut chewing in Indians as well as other nationalities adopting the oral habit of betel-nut chewing, (2) it is generally accepted to be a premalignant condition of the oral cavity.This paper reviews the disease and presents a severe case of this malady recorded in an Indian who chews pan-supari.

    Full Text Available The hair cosmetic industry has undergone a revolutionary change over the last two decades. The focus has dramatically veered from merely cleaning to repair, increasing the tensile strength, reducing oxidative damage, and stimulating growth. Newer shorter procedures to make hair look naturally more lustrous, smooth, and manageable have evolved. Specialized grooming products have been formulated to cleanse, calm, and condition the hair, and are tailored for different hair-types, for example, dry, dry-damaged, oily, colored, and gray hair. Other products are formulated to alter the color or structure of the hair shaft, for example, hair dyes, perming/relaxing. Hair sprays and waxes/gels, can alter the ′lift′ of the hair-shaft. Although dermatologists are experts in managing scalp and hair diseases, the esthetic applications of newer cosmetic therapies still remain elusive. This article attempts to fill the lacunae in our knowledge of hair cosmetics and esthetic procedures relevant in today′s rapidly changing beauty-enhancing industry, with special emphasis on the Indian scenario for chemical and ′natural′ hair products.

    The study represents an attempt at employing segmental hair analysis in complex poisonings with xenobiotic mixtures of heroine - cocaine - amphetamines in the context of the cause of death as a consequence of complex interaction mechanisms which occurred prior to death. Two cases of complex poisonings: heroine - cocaine and heroine - cocaine - amphetamines were analyzed and documented with macro- and microscopic examinations and complex toxicological examinations, including the analysis of classic biological material, i.e. samples of selective blood, and alternative material, i.e. hair samples. Determinations of opioids, cocaine and its metabolite and amphetamines in the hair biological matrix were performed using high performance liquid chromatography--atmospheric pressure chemical ionization--tandem mass spectrometry (HPLC-APCI-MS-MS). Segmental hair analysis of the investigated cases indicated a prolonged intake of similar psychoactive substances and a developed adaptation of the addicted to interaction mechanisms, which, however, led gradually to multiorgan anatomopathological changes, and in consequence to death.

    The Oral HIV/AIDS Research Alliance (OHARA) is part of the AIDS Clinical Trials Group (ACTG), the largest HIV clinical trials organization in the world. Its main objective is to investigate oral complications associated with HIV/AIDS as the epidemic is evolving, in particular, the effects of antiretrovirals on oral mucosal lesion development and associated fungal and viral pathogens. The OHARA infrastructure comprises: the Epidemiologic Research Unit (at the University of California San Francisco), the Medical Mycology Unit (at Case Western Reserve University) and the Virology/Specimen Banking Unit (at the University of North Carolina). The team includes dentists, physicians, virologists, mycologists, immunologists, epidemiologists and statisticians. Observational studies and clinical trials are being implemented at ACTG-affiliated sites in the US and resource-poor countries. Many studies have shared end-points, which include oral diseases known to be associated with HIV/AIDS measured by trained and calibrated ACTG study nurses. In preparation for future protocols, we have updated existing diagnostic criteria of the oral manifestations of HIV published in 1992 and 1993. The proposed case definitions are designed to be used in large-scale epidemiologic studies and clinical trials, in both US and resource-poor settings, where diagnoses may be made by non-dental healthcare providers. The objective of this article is to present updated case definitions for HIV-related oral diseases that will be used to measure standardized clinical end-points in OHARA studies, and that can be used by any investigator outside of OHARA/ACTG conducting clinical research that pertains to these end-points.

    Fanconi anemia (FA) is a rare autosomal recessive genetic disorder characterized by aplastic anemia, progressive pancytopenia, congenital anomalies, and increased risk of cancer development. After hematopoietic stem cell transplant (HSCT), patients have an estimated 500-fold increase in the risk of developing head and neck cancer compared to a non-affected, and the oral cavity is affected in one-third of cases. Thus, this study aimed to better understand the natural history of oral cavity cancer in patients affected by FA. After conducting a keyword search on MEDLINE, we found 121 cases of oral cavity cancer in patients who had been affected by FA. In conclusion, HSCT may increase the risks of oral cancer development, especially after 5 years after the transplant. In the normal population, the tongue is the most affected area. FA patients should be informed of the risks of oral malignant transformation and encouraged to be undergo medical surveillance. Copyright © 2018 Elsevier B.V. All rights reserved.

    TrichoScan Professional is a computerized program used for digital measurement of hair growth and hair loss. The aim of our study was to undertake an evaluation with TrichoScan Professional of female patients consulting at our hospitals for hair loss. The purpose of our study was to determine whether TrichoScan was able to identify differences in hair parameters that would correlate with the pattern of alopecia or according to the age of the patients evaluated. One hundred-eighty women that consulted consecutively for loss of hair were included. Patients were aged between 8 and 85 years (mean age 36 years). Data including age, the number of hairs, hair density per square centimetre, anagen and telogen percentage and percentage of terminal and miniaturized hair were analysed. Results observed with TrichoScan were as below: number of hairs (mean 154.9; range 34-316). Hair density per square centimetre (mean 239; range 52-486). Hair in anagen phase (mean 62.4%; range 9-93%). Hair in telogen phase (mean 37.4%; range 7-91%). Terminal hair (mean 95.2%; range 82-100%). Vellus hair (mean 4.7%; range 0-17%). Pearson's correlation test was used to measure the strength of the association of age with the rest of parameters. The statistical analysis showed a significant correlation between age and both the number of hairs and the hair density per square centimetre. However, no significant correlation between age and rest of the parameters was observed. TrichoScan Professional may help to quantify hair density and in our sample, this was the only parameter showing a significant decrease according to age in various types of alopecia affecting the females. © 2010 The Authors.

    Although the exact incidence of pediatric oral lichen planus (OLP) is unknown, the oral mucosa seems to be less commonly involved, and the clinical presentation is often atypical. The aim of the study is to present a case series of OLP in childhood. From our database, we retrospectively selected and analyzed the clinical data of OLP patients under the age of 18 where the diagnosis had been confirmed by histopathological analysis. The case series from our database shows eight patients, four males and four females. The mean (±SD) age at the time of diagnosis of the disease was 13.5 (±2.73) years, ranging in age from 9 to 17. Clinically, a reticular pattern was present in six patients (75%), and the tongue was the most commonly involved oral site (six cases, 75%). We also report the first case of OLP in a 9-year-old girl affected by autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy. We report the largest case series of pediatric OLP published in literature thus far. Differences in the disease between adults and pediatric patients have been detected, but further investigation and a larger case series are needed to establish any detailed differences in clinical outcomes. © 2017 The International Society of Dermatology.

    The social use of betel nut is relatively common in certain geographic areas, especially India and Southeast Asia. The term betel nut does not truly describe the product that is chewed; rather, the term quid is more accurate because it refers to a substance or mixture of substances, including the areca nut, that are chewed and remain in contact with the mucosa. Betel quid is a type of quid that contains betel leaf. Chewer's mucosa and oral submucous fibrosis are clinical entities that have been associated with betel quid use. We report a case of oral lichen planus induced by betel quid use in a 79-year-old Cambodian woman.

    Full Text Available Lymphangiomas are benign hamartomatous tumors of the lymphatic channels which present as developmental malformations arising from sequestration of lymphatic tissue that do not communicate with the rest of the lymphatic channels. Lymphatic vessels are filled with a clear protein-rich fluid containing few lymph cells. It can also occur in association with hemangioma. The onset of lymphangiomas are either at birth (60% to 70% or up to two years of age (90% and rare in adults. Lymphangiomas have marked predilection for the head and neck region (50-70%. The most common location in the mouth is the dorsum of tongue, followed by lips, buccal mucosa, soft palate, and floor of the mouth. On tongue, they may present as a localized or a diffused growth which may enlarge to cause macroglossia, impaired speech and difficulty in mastication. Herewith, we present a rare case of lymphangioma of tongue leading to macroglossia in a 8-year-old boy.

    Focal epithelial hyperplasia or Heck's disease is an infrequent asymptomatic condition caused by human papillomavirus types 13 or 32 affecting the mucous membrane of the mouth and is commonly seen in young individuals. Firstly, it was described in Indians and Eskimos, but it exists in various populations. We present three cases of Heck's disease in an Afghan immigrant family group living in Iran that seem to have familial predominance. The disease was identified as oral focal epithelial hyperplasia on the basis of histopathologic and clinical findings. The lesions were reduced significantly after 4 months of good oral hygiene. Dentists should be familiar with the clinical manifestations of these types of lesions that affect the oral cavity. In fact, histopathologic assessment and clinical observation are necessary to establish the diagnosis.

    Full Text Available Myiasis is derived from a Latin word "Muia," which means fly and "iasis," which means disease. It is a pathological condition in which there is an infestation of living mammals with the dipterous larvae, which, at least for a certain period feed on the host′s dead or living tissue and develop as parasites. Oral myiasis is a rare pathology in humans and is associated with poor oral hygiene, alcoholism, senility, suppurating lesions, severe halitosis, malignancy, low socioeconomic status and others conditions. The treatment consists of mechanical removal of the maggot one by one along with a systemic treatment of ivermectin, a semi-synthetic macrolide antibiotic. We present a case report of a 25-year-old man with intellectual disability, poor oral hygiene, epilepsy, with a deep lacerated wound in the gingiva of maxillary anterior region with acute swelling of the upper lip and presence of larvae of maggot.

    2014-01-01

    Full Text Available Primary malignant melanoma is a rare and aggressive neoplasm that originates from the proliferation of melanocytes. Although, it comprises 1.3% of all cancers, malignant melanoma of the oral cavity accounts for only 0.2-8% of all reported melanomas and occurs approximately 4 times more frequently in the oral mucosa of the upper jaw, usually on the palate or alveolar gingivae. Most of the mucosal melanomas are usually asymptomatic in early stages, and presents as pigmented patch or a mass delaying the diagnosis until symptoms of swelling, ulceration, bleeding, or loosening of teeth are noted. The prognosis is extremely poor, especially in advanced stages. Therefore, any pigmented lesion of undetermined origin should always be biopsied. We herewith report of two cases of oral malignant melanoma in a 60 and 75-year-old female.

    Full Text Available Crohn´s disease is a chronic inflammatory bowel disease still with unknown etiology. In 0.5-20 % of patients, extraintestinal lesions in the oral cavity can be presented in forms of orofacial granulomatosis, cobblestone and corrugated oral mucosa, mucosal tags, deep linear ulcerations with hyperplastic folds, pyostomatits vegetans, aphthous ulcers, angular cheilitis, labial/facial edema and gingival erythema/edema. We describe a case of a 28-year-old male who was presented with oral lesions of Crohn´s disease and treatment procedure. The patient was candidate for biologic treatment so dental procedures and preparation of the patient for treatment are described. Good communication and cooperation between the patient's doctor and dentist are important for successful treatment.

    2015-01-01

    Organ abscesses are rare, life-threatening complications that can be caused by bacteremia from oral infections. Metastatic infection is a well-established concept. Dental and periapical infections can cause infections in distant organs and tissues. The frequency of these systemic infections and systemic diseases is open to debate, as some patients are more susceptible to infections than others. This article presents the case report of a 52-year-old woman who was hospitalized with a hepatic abscess after a routine periodontal maintenance procedure. The patient had poor oral health, involving several nonrestorable teeth, multiple failed endodontic treatments, and asymptomatic chronic periapical pathologies. Her dental history included previous diagnoses of moderate generalized chronic periodontitis and advanced localized periodontitis. It was possible that bacteremia developed during her most recent dental treatment, leading to the hepatic abscess. Systemic antibiotic therapy, drainage of the hepatic abscess, and oral rehabilitation resulted in complete recovery.

    2013-01-01

    Full Text Available White lesions both physiologic as well as pathologic are relatively frequent in the oral cavity, the most common pathology being oral leukoplakia (OL. There are many variants of OL, one of which is oral proliferative verrucous leukoplakia (OPVL. OPVL is a rare clinico-pathological entity, which is slow growing, long-term progressive lesion, but remains an enigmatic and difficult to define. The etiology of OPVL remains still unclear. Tobacco use does not seem to have a significant influence on the appearance of OPVL. These lesions may occur both in smokers and non-smokers. It is observed more frequently in women and elderly patients over 60 years at the time of diagnosis. The buccal mucosa and tongue are the most frequently involved sites. It develops initially as a white plaque of hyperkeratosis that eventually becomes a multifocal disease with confluent, exophytic and proliferative features. Various published case series have presented OPVL as a disease with aggressive biological behavior due to its high probability of recurrence and a high rate of malignant transformation. Prognosis is poor for this seemingly harmless-appearing white lesion of the oral mucosa. This article describes the clinical aspects and histologic features of an OPVL case that demonstrated the typical behavior pattern in a long-standing, persistent lesion and discusses this relatively rare entity in light of current information.

    Masuda, Ikuya; Matsuo, Toshihiko; Okamoto, Kazuo; Matsushita, Kyoko; Ohtsuki, Hiroshi

    2010-01-01

    To report 2 cases of corneal perforation associated with the use of oral nonsteroidal anti-inflammatory drugs (NSAIDs). In a 62-year-old woman and a 79-year-old woman, corneal perforation occurred after 7 days and 5 months of oral NSAIDs administration, respectively. After NSAIDs were discontinued, the cornea epithelialized and the anterior chamber formed within 14 and 10 days, respectively. It is well known that topical NSAIDs cause corneal perforation. Observations in the present cases suggest that the oral administration of NSAIDs may also cause corneal damage, and hence, medical professionals should consider the risk of damage to the cornea when administering these drugs orally.

    We developed and validated a method to detect and quantify 12 anabolic steroids in blood (androstenedione, dihydrotestosterone, boldenone, epitestosterone, mesterolone, methandienone, nandrolone, stanozolol, norandrostenedione, tamoxifene, testosterone, trenbolone) and eight more in hair samples (nandrolone phenylpropionate, nandrolone decanoate, testosterone propionate, testosterone benzoate, testosterone cypionate, testosterone decanoate, testosterone phenylpropionate, testosterone undecanoate) using liquid chromatography coupled to high-resolution mass spectrometry. This method used a benchtop Orbitrap mass spectrometer operating with an APCI probe under positive ionization mode. Analysis was realized in full scan experiment with a nominal resolving power of 140,000. After addition of the internal standard (testosterone-D3) and incubation in phosphate buffer pH = 5 for hair, 200 μL of blood and 30 mg of hair samples were extracted with heptane. LOQ and LOD were determined at 5 and 1 ng mL -1 in whole blood and 10 to 100 pg mg -1 and 2 to 20 pg mg -1 in hair according to the compounds, respectively. The method was linear in the 5-1000 ng mL -1 range in whole blood and between 10 or 100 pg mg -1 and 1000 pg mg -1 in hair with correlation coefficients >0.99, and intra- and inter-day accuracy and precision were <14.8% for all compounds except for some esters in hairs (<19.9%) probably due to an important matrix effect for these compounds. This sensitive and specific method to detect anabolic steroids has been successfully applied to two real cases, for which various anabolic steroids in whole blood, urine, and hair were identified and quantified.

    Cutaneous human papillomaviruses (HPV) have been reported in cutaneous squamous cell carcinoma (SCC). We conducted a clinic-based case-control study to investigate the association between genus-beta HPV DNA in eyebrow hairs (EBH) and SCC. EBH from 168 SCC cases and 290 controls were genotyped for genus-beta HPV DNA. SCC tumors from a subset of cases (n = 142) were also genotyped. Viral load was determined in a subset of specimens positive for a single HPV type. Associations with SCC were estimated by odds ratios (OR) and 95% confidence intervals (CI) adjusted for age and sex using logistic regression. Statistical tests were two-sided. EBH DNA prevalence was greater in cases (87%) than controls (73%) (p genus-beta types tested, when accounting for DNA for the same HPV type in the tumor (ORs = 3.44-76.50). Compared to controls, the mean viral DNA load in EBH among the selected cases was greater for HPV5, HPV8 and HPV24, but lower for HPV38. SCC cases were more likely than controls to have HPV DNA+ EBH for single and multiple HPV types, providing additional support for the potential role of genus-beta HPV infections in SCC development. © 2013 UICC.

    2015-12-01

    Full Text Available A 70-year-old Japanese man presented at our hospital with an asymptomatic, blackish, irregularly shaped plaque with a gray nodule in the periphery on his left lower leg. The lesion had been present for 10 years and had recently enlarged, associated with bleeding. Histopathologically, the tumor consisted of three distinct parts: The first part showed massive aggregation of basophilic basaloid cells with peripheral palisading and abundant melanin granules, and was diagnosed as solid-type basal cell carcinoma. The second part showed aggregation of clear cells with squamous eddies, and was diagnosed as proliferating trichilemmal tumor. The third part showed reticular aggregation of basaloid cells with infundibular cysts in the papillary dermis, and was diagnosed as infundibulocystic basal cell carcinoma. We diagnosed this tumor as basal cell carcinoma with various forms of hair follicle differentiation, including differentiation into the outer root sheath.

    2008-08-01

    The impact of male hair loss as a personal and social marker of aging is tremendous and its persistence as a human concern throughout recorded history places it in the forefront of male concern about the physical signs of aging. Restoration of the frontal hairline has the visual effect of re-establishing facial symmetry and turning back time. Follicular unit transplantation has revolutionized hair restoration, with its focus on redistributing large numbers of genetically stable hair to balding scalp in a natural distribution. Follicular unit hair restoration surgery is a powerful tool for the facial plastic surgeon in male aesthetic facial rejuvenation because it offers high-impact, natural-appearing results with minimal downtime and risk for adverse outcome.

  18. Endocrine disruptors in the workplace, hair spray, folate supplementation, and risk of hypospadias: case-control study.

    Hypospadias is one of the most common urogenital congenital anomalies affecting baby boys. Prevalence estimates in Europe range from 4 to 24 per 10,000 births, depending on definition, with higher rates reported from the United States. Relatively little is known about potential risk factors, but a role for endocrine-disrupting chemicals (EDCs) has been proposed. Our goal was to elucidate the risk of hypospadias associated with occupational exposure of the mother to endocrine-disruptor chemicals, use of folate supplementation during pregnancy, and vegetarianism. We designed a case-control study of 471 hypospadias cases referred to surgeons and 490 randomly selected birth controls, born 1 January 1997-30 September 1998 in southeast England. Telephone interviews of mothers elicited information on folate supplementation during pregnancy and vegetarianism. We used a job exposure matrix to classify occupational exposure. In multiple logistic regression analysis, there were increased risks for self-reported occupational exposure to hair spray [exposed vs. nonexposed, odds ratio (OR) = 2.39; 95% confidence interval (CI), 1.40-4.17] and phthalate exposure obtained by a job exposure matrix (OR = 3.12; 95% CI, 1.04-11.46). There was a significantly reduced risk of hypospadias associated with of folate use during the first 3 months of pregnancy (OR = 0.64; 95% CI, 0.44-0.93). Vegetarianism was not associated with hypospadias risk. Excess risks of hypospadias associated with occupational exposures to phthalates and hair spray suggest that antiandrogenic EDCs may play a role in hypospadias. Folate supplementation in early pregnancy may be protective.

    2015-01-01

    Intravenous sedation is frequently provided by anesthesiologists for phobic patients undergoing elective dental treatment in outpatient settings. Propofol is one of the most commonly used anesthetic agents that can result in apnea and respiratory depression, thereby posing potential difficulties with perioperative airway management. Dexmedetomidine has been utilized successfully in intravenous sedation for a wide variety of procedures and holds potential as an alternative to propofol in outpatient dental settings. However, as a single agent, it may not provide adequate depth of sedation and analgesia for oral rehabilitation. In this case report we demonstrate an effective alternative intravenous deep-sedation technique for an adult phobic patient undergoing oral rehabilitation utilizing 3 agents in combination: dexmedetomidine, ketamine, and midazolam. This combination of agents may be especially useful for those patients with a history of substance abuse, where administration of opioids may be undesirable or contraindicated.

    Full Text Available Snus (nass is a form of snuff used in a similar manner to American dipping tobacco, but it does not typically result in a need for spitting. Possible hazards associated with this material include malignant and premalignant lesions in the oral cavity and gastrointestinal tract. The use of smokeless tobacco has increased in the Middle East in recent decades, particularly among teenagers and young adults. Therefore, practitioners must be able to recognize malignant and premalignant lesions. Although, an estimated 10-25% of the world′s population uses smokeless tobacco, this practice is virtually unknown in Iran. The aim of this study is to report a series of cases of squamous cell carcinoma and verrucous carcinoma occurring in the users of snus, who referred to the Department of Oral Medicine in Kerman Dental School.

    2017-01-01

    Acute hair felting is a rare disorder of scalp hair. In this condition, the hair becomes twisted, entangled as a hard stony mass resembling a bird's nest. Sudden hair matting has been reported earlier in the literature after vigorous use of chemical and herbal shampoos. Plica polonica is a patchy area of hair matting occurring in due course of time in neglected hair or underlying psychiatric illness. This case is interesting as the whole scalp hair matted immediately after using coconut oil and castor oil following washing. Growing long hair and taking oil bath are cultural and religious customs in South India. The high viscosity of castor oil and long hair had contributed to sudden felting of hair. This disorder of hair is irreversible and the hair should be cut off. Acute nature of this disorder will result in a serious psychological impact on the patient and the family.

    2016-01-01

    Hair is typically modeled and rendered using either explicitly defined hair strand geometry or a volume texture of hair densities. Taken each on their own, these two hair representations have difficulties in the case of animal fur as it consists of very dense and thin undercoat hairs in combination...... with coarse guard hairs. Explicit hair strand geometry is not well-suited for the undercoat hairs, while volume textures are not well-suited for the guard hairs. To efficiently model and render both guard hairs and undercoat hairs, we present a hybrid technique that combines rasterization of explicitly...... defined guard hairs with ray marching of a prismatic shell volume with dynamic resolution. The latter is the key to practical combination of the two techniques, and it also enables a high degree of detail in the undercoat. We demonstrate that our hybrid technique creates a more detailed and soft fur...

  5. A case-control study of maternal periconceptual and pregnancy recreational drug use and fetal malformation using hair analysis.

    Full Text Available OBJECTIVE: Maternal recreational drug use may be associated with the development of fetal malformations such as gastroschisis, brain and limb defects, the aetiology due to vascular disruption during organogenesis. Using forensic hair analysis we reported evidence of recreational drug use in 18% of women with a fetal gastroschisis. Here we investigate this association in a variety of fetal malformations using the same method. METHODS: In a multi-centre study, women with normal pregnancies (controls and those with fetal abnormalities (cases gave informed consent for hair analysis for recreational drug metabolites using mass spectrometry. Hair samples cut at the root were tested in sections corresponding to 3 month time periods (pre and periconceptual period. RESULTS: Women whose fetus had gastroschisis, compared to women with a normal control fetus, were younger (mean age 23.78 ± SD4.79 years, 18-37 vs 29.79 ± SD6 years, 18-42, p = 0.00001, were more likely to have evidence of recreational drug use (15, 25.4% vs 21, 13%, OR2.27, 95thCI 1.08-4.78, p = 0.028, and were less likely to report periconceptual folic acid use (31, 53.4% vs 124, 77.5%, OR0.33, 95thCI 0.18-0.63, p = 0.001. Age-matched normal control women were no less likely to test positive for recreational drugs than women whose fetus had gastroschisis. After accounting for all significant factors, only young maternal age remained significantly associated with gastroschisis. Women with a fetus affected by a non-neural tube central nervous system (CNS anomaly were more likely to test positive for recreational drugs when compared to women whose fetus was normal (7, 35% vs 21, 13%, OR3.59, 95th CI1.20-10.02, p = 0.01. CONCLUSIONS: We demonstrate a significant association between non neural tube CNS anomalies and recreational drug use in the periconceptual period, first or second trimesters, but we cannot confirm this association with gastroschisis. We confirm the association of

    2016-09-01

    Hair loss is both a common chief complaint by patients and a clinical challenge for physicians, especially general practitioners, yet few dermatological problems yield as much patient satisfaction when resolved as hair loss. The diagnosis is often attributed to androgen-related hair loss, while other causes, some of which are life-threatening but treatable, are overlooked. We searched for relevant literature on hair loss and supported these findings with our clinical experience to identify seven major systemic etiologies of hair loss, ranging from infectious agents to consumption of unsafe supplements. Many causes are only described in the literature through case studies, though some original articles and meta-analyses are available. Careful history taking, proper examination techniques, and judicious use of laboratory tests are essential to reach at the correct diagnosis in a cost-effective manner when performing patient work-up. Such methodical evaluation of hair loss can result in the appropriate treatment plan and provide significant patient satisfaction. Key messages Hair loss is a common chief complaint and a difficult challenge for both general practitioners and dermatology consultants. We identified seven major categories of systemic hair loss etiology and present a framework for their clinical evaluation. A methodical approach to hair loss can result in the appropriate treatment plan and provide significant patient satisfaction.

  7. Three cases of radiation-induced cancer in oral regions

    Three cases of radiation-induced cancer in the oral regions were reported with relation to radiation therapy. One was the general radiation-induced cancer following radiotherapy for the hemangioma. The other two cases, which belonged in the B-1 group of Sakai and his coworker's diagnostic criteria for radiation-induced cancer, were those occurring after radiotherapy for the malignant tumors. Due to the relatively high dosage exposure by the patient in the radiotherapy it is necessary to look out the latency of the radiation-induced cancer. After radiotherapy, careful and periodical observation is important for immediate treatment in an early stage for the radiation-induced cancer to have a favorable prognosis. In addition careful observation of the changes after radiotherapy helps in discovering the precancerous lesions from the therapy. For the radiation-induced cancer, surgical treatment would be the best, however, radiation therapy is also effective in certain cases. (author)

  8. Significant enhancement of 11-Hydroxy-THC detection by formation of picolinic acid esters and application of liquid chromatography/multi stage mass spectrometry (LC-MS(3) ): Application to hair and oral fluid analysis.

    Formation of picolinic acid esters of hydroxylated drugs or their biotransformation products is a promising tool to improve their mass spectrometric ionization efficiency, alter their fragmentation behaviour and enhance sensitivity and specificity of their detection. The procedure was optimized and tested for the detection of cannabinoids, which proved to be most challenging when dealing with alternative specimens, for example hair and oral fluid. In particular, the detection of the THC metabolites hydroxyl-THC and carboxy-THC requires ultimate sensitivity because of their poor incorporation into hair or saliva. Both biotransformation products are widely accepted as incorporation markers to distinguish drug consumption from passive contamination. The derivatization procedure was carried out by adding a mixture of picolinic acid, 4-(dimethylamino)pyridine and 2-methyl-6-nitrobenzoic anhydride in tetrahydrofuran/triethylamine to the dry extraction residues. Resulting derivatives were found to be very stable and could be reconstituted in aqueous or organic buffers and subsequently analyzed by liquid chromatography-mass spectrometry (LC-MS). Owing to the complex consecutive fragmentation patterns, the application of multistage MS3 proved to be extremely useful for a sensitive identification of doubly picolinated hydroxy-THC in complex matrices. The detection limits - estimated by comparison of corresponding signal-to-noise ratios - increased by a factor of 100 following picolination. All other species examined, like cannabinol, THC, cannabidiol, and carboxy-THC, could also be derivatized exhibiting only moderate sensitivity improvements. The assay was systematically tested using hair samples and exemplarily applied to oral fluid. Concentrations of OH-THC identified in THC-positive hair samples ranged from 0.02 to 0.29pg/mg.

  9. Large oral lipoma: Case report and literature review in Iran

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Lipoma is a benign mesenchymal tumor of fat with uncertain pathogenesis. Although the most common mesenchymal neoplasm in trunk and proximal portions of the extremities, it is rarely seen in the oral cavity. Oral lipomas are clinically soft, smooth-surfaced nodular masses that mostly are less than 3 cm in size. Typically the tumor is asymptomatic unless bitten or become noticeable because of their size. The buccal mucosa and buccal vestibule are the most common intraoral sites and account for 50% of all cases. Reported here is a relatively large lipoma of buccal mucosa that was treated surgically under local anesthesia. In an 18-month postsurgical follow up no complication or recurrence has occurred. This case will also be compared to intraoral lipomas reported in Iranian population. As lipomas are usually smaller than 3 cm in diameter, lipoma with the size reported, is of clinical importance. Since the large lipomas are in differential diagnosis with other, even malignant, mesenchymal, or salivary gland tumors. Thus, this case report recommends clinical awareness in diagnosis of large intraoral soft tissue lesions.

    The krokodil use disorder is an addictive pathology with quite severe organic effects, especially at the skin level, that causes severe and degenerative necrosis of blood and muscle tissue. Though this disorder has a low prevalence in Spain, compared to the large number of consumers in other countries such as Ukraine or Russia, its consumption is slowly but gradually expanding in countries of the European Union and America. The simplicity of the process of obtaining the substance from desomorphine, together with its high availability and low cost, contribute toward consumers' self-sufficiency. This article presents the case of a user of krokodil and reviews the clinical symptoms of oral ingestion.

    The study showed male preponderance affecting individuals in second and third decades of life. All the patients had the habit of chewing betel leaves, betel nuts, tobacco, gutkha, alone or in various combinations. The associated causative factors were high chilli intake, nutritional deficiencies, and the clinical features were varied such as burning sensation, intolerance to spicy food, restricted mouth opening and difficulty in speech and deglutition. Histopathology was the characteristic of OSMF and was consistent with clinical grades of the disease but could not be corelated to the degree of mouth opening. The study of 101 cases of oral submucous fibrosis is reported.

    The elution of the neutron activated elements out of hair soaked in some organic solvents and EDTA solution was studied. Soakage of the hair sample, which was washed with water and acetone in advance as IAEA's proposal, in ether and acetone for 30 minutes each resulted in no elution of Hg, Zn, Co and Se. Elution of Zn and Co from the powdered hair sample soaked in 0.1 M EDTA solution was rapid, while Zn did not elute out from the cut hair (2 -- 3 mm length) on the same condition. Hg, Se and Au were not eluted out by 0.1 M EDTA solution in the both case of cut hair and of powdered hair. Br was removed by 0.1 M EDTA solution from the cut hair and from the powdered hair with equal ease. (author)

    2007-09-01

    Oral melanoacanthoma (MA) is a rare, benign pigmented lesion, similar to cutaneous MA, characterized by hyperplasia of spinous keratinocytes and dendritic melanocytes. The pathogenesis of oral MA remains uncertain, although its clinical behavior is suggestive of a reactive origin. The most common intraoral sites are the buccal mucosa, lip, palate and gingiva. The average age of presentation is 28 years, mainly in blacks, with a strong female predilection. The oral melanotic macule (MM) is a small, well-circumscribed brown-to-black macule that occurs on the lips and mucous membranes. The etiology is not clear and it may represent a physiologic or reactive process. The average age of presentation is 43 years, with a female predilection. A biopsy is recommended to distinguish these lesions from each other and from other oral melanocytic lesions. We depict four cases each of oral MA and MM, affecting Caucasian and Latin American mestizo patients. The clinicopathological features of these cases reflect its ample spectrum, and to the best of our knowledge, it is the first example of oral MA affecting a Caucasian boy reported in the English literature. Therefore oral MA and MM should be considered in the differential diagnosis of pigmented lesions in the oral mucosa in these populations.

  18. Topical Valproate Solution for Hair Growth

    2018-05-01

    Full Text Available Valproate is used regularly in the treatment of various seizure disorders, bipolar disorder, migraine prophylaxis and off label in many other conditions. Alopecia or hair loss is cosmetic side effect of oral valproate administration. Hair loss with valproate is diffused, non-scarring and dose related. A large number of drugs may interfere with the hair cycle and produce hair loss. We have only a few drugs like Minoxidil, Finasteride used for hair regeneration and both have its own side effects and limitations. In contrast to oral ingestions of valproate causing hair loss, early experiments with topical Valproic acid cream showed hair regeneration. Valproic acid cream is currently unavailable in the market, alternatively, we do have valproate and divalproex solutions available in various strengths which have a potential to be used topically for hair regeneration. The side effects and cost of topical valproate solution could be much less than the available options in the market. Valproate solution topically has the potential to be used for hair growth.

    2016-09-01

    There are persistent concerns about litigation in the dental and medical professions. These concerns arise in a setting where general dentists are more frequently undertaking a wider range of oral surgery procedures, potentially increasing legal risk. Judicial cases dealing with medical negligence in the fields of general dentistry (oral surgery procedure) and oral and maxillofacial surgery were located using the three main legal databases. Relevant cases were analysed to determine the procedures involved, the patients' claims of injury, findings of negligence and damages awarded. A thematic analysis of the cases was undertaken to determine trends. Fifteen cases over a 20-year period were located across almost all Australian jurisdictions (eight cases involved general dentists; seven cases involved oral and maxillofacial surgeons). Eleven of the 15 cases involved determinations of whether or not the practitioner had failed in their duty of care; negligence was found in six cases. Eleven of the 15 cases related to molar extractions (eight specifically to third molar). Dental and medical practitioners wanting to manage legal risk should have regard to circumstances arising in judicial cases. Adequate warning of risks is critical, as is offering referral in appropriate cases. Preoperative radiographs, good medical records and processes to ensure appropriate follow-up are also important. © 2015 Australian Dental Association.

    2015-01-01

    We describe the diversity of indications for laser hair removal (LHR) therapy and compare our experience with the literature. Patients' case notes referred to the Birmingham Regional Skin Laser Centre between 2003 and 2011 for laser hair removal, with indications other than hirsutism, were reviewed retrospectively. Thirty-one treated patients with the following indications were identified: hair-bearing skin grafts/flaps, intra-oral hair-bearing flap, Becker's naevus, localised nevoid hypertrichosis, peristomal hair-bearing skin, scrotal skin prior to vaginoplasty in male-to-female (MTF) gender reassignment, pilonidal sinus disease (PSD), pseudofolliculitis barbae (PFB) and hidradenitis suppurativa (HS). Seven patients with the following indications have been reported before: intra-oral hair-bearing graft, naevoid hypertrichosis and peristomal hair-bearing skin. A clinical review of the evidence available for each indication is provided. Our experience and that in the published literature suggest that LHR is a safe, well-tolerated and effective treatment modality for the indications we report, leading to significant symptom and functional improvement with high patient satisfaction. LHR appears effective in the treatment of chronic inflammatory conditions such as PSD, PFB and HS, particularly at an early disease stage. We aim to increase awareness of the diversity of laser hair removal indications and add evidence to the medical literature of the wide range of indications for this useful treatment modality.

    Full Text Available Loose anagen hair syndrome (LAHS is an underestimated cause of noncicatricial alopecia among children, manifesting as thin, sparse or fine hair. We report a case of LAHS clinically presenting as diffuse woolly hair, an association rarely described in the literature. In addition, we review the clinical as well as genetic link between these two enigmatic hair disorders and hypothesize that both may be associated in a yet unknown manner.

    Lysergic acid diethylamide (LSD) is administered in low dosages, which makes its detection in biological matrices a major challenge in forensic toxicology. In this study, two sensitive and reliable methods based on liquid chromatography-tandem mass spectrometry (LC-MS/MS) were established and validated for the simultaneous determination of LSD and its metabolite, 2-oxo-3-hydroxy-LSD (O-H-LSD), in hair and urine. Target analytes in hair were extracted using methanol at 38°C for 15h and analyzed by LC-MS/MS. For urine sample preparation, liquid-liquid extraction was performed. Limits of detection (LODs) in hair were 0.25pg/mg for LSD and 0.5pg/mg for O-H-LSD. In urine, LODs were 0.01 and 0.025ng/ml for LSD and O-H-LSD, respectively. Method validation results showed good linearity and acceptable precision and accuracy. The developed methods were applied to authentic specimens from two legal cases of LSD ingestion, and allowed identification and quantification of LSD and O-H-LSD in the specimens. In the two cases, LSD concentrations in hair were 1.27 and 0.95pg/mg; O-H-LSD was detected in one case, but its concentration was below the limit of quantification. In urine samples collected from the two suspects 8 and 3h after ingestion, LSD concentrations were 0.48 and 2.70ng/ml, respectively, while O-H-LSD concentrations were 4.19 and 25.2ng/ml, respectively. These methods can be used for documenting LSD intake in clinical and forensic settings. Copyright © 2015 Elsevier B.V. All rights reserved.

  4. The Current Status of Microscopical Hair Comparisons

    Full Text Available Although the microscopical comparison of human hairs has been accepted in courts of law for over a century, recent advances in DNA technology have called this type of forensic examination into question. In a number of cases, post-conviction DNA testing has exonerated defendants who were convicted in part on the results of microscopical hair comparisons. A federal judge has held a Daubert hearing on the microscopical comparison of human hairs and has concluded that this type of examination does not meet the criteria for admission of scientific evidence in federal courts. A review of the available scientific literature on microscopical hair comparisons (including studies conducted by the Royal Canadian Mounted Police and the Federal Bureau of Investigation leads to three conclusions: (1 microscopical comparisons of human hairs can yield scientifically defensible conclusions that can contribute to criminal investigations and criminal prosecutions, (2 the reliability of microscopical hair comparisons is strongly affected by the training of the forensic hair examiner, (3 forensic hair examiners cannot offer estimates of the probability of a match of a questioned hair with a hair from a randomly selected person. In order for microscopical hair examinations to survive challenges under the U.S. Supreme Court’s Daubert decision, hair microscopists must be better trained and undergo frequent proficiency testing. More research on the error rates of microscopical hair comparisons should be undertaken, and guidelines for the permissible interpretations of such comparisons should be established. Until these issues have been addressed and satisfactorily resolved, microscopical hair comparisons should be regarded by law enforcement agencies and courts of law as merely presumptive in nature, and all microscopical hair comparisons should be confirmed by nuclear DNA profiling or mitochondrial DNA sequencing.

    Oral melanoacanthoma is a mucocutaneous, pigmented, rare, benign, and probably reactive lesion. This paper reports for the first time in the literature a case of multifocal oral melanoacanthoma in a patient diagnosed with Addison's disease and concomitant Graves' disease with hyperthyroidism. The patient presented with oral pigmented lesions, which were hypothesized to be mucosal pigmentation associated with Addison's disease. Due to their unusual clinical pattern, these oral lesions were biopsied and diagnosed as oral melanoacanthoma on histopathology and immunohistochemistry for HMB-45. At the moment of this report, the patient was being treated for her systemic conditions, but the lesions had not regressed. Reactive hyperpigmentation of the skin and mucous membranes may be found in Addison's disease and hyperthyroidism. This case reinforces the hypothesis of a reactive nature for oral melanoacanthoma and highlights the need for investigation of endocrine disorders in patients with multifocal oral melanoacanthoma.

  6. Body to scalp: Evolving trends in body hair transplantation

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Follicular unit extraction (FUE is becoming an increasingly popular method for hair restoration. As FUE leaves behind no linear scars, it is more suitable to harvest from various body areas including beard, chest, and extremities in hirsute individuals. Body hair characteristics such as thickness, length, and hair cycle may not completely match to that of the scalp hair. The techniques of harvesting body hairs are more time consuming, requiring higher degree of skill than regular scalp FUE. Body hair transplantation can be successfully used either alone or in combination with scalp hair in advanced grades of baldness, for improving the cosmetic appearance of hairlines and in scarring alopecia when there is paucity of donor scalp hair. Harvesting of body hairs opens up a new viable donor source for hair restoration surgeons, especially in cases of advanced Norwood grades five and above of androgenetic alopecia.

    Traumatic ulcerative granuloma with stromal eosinophilia (TUGSE) is a special oral ulcerative lesion that shares many clinical features of an oral squamous cell carcinoma. This study reports the clinicopathological features of 34 oral TUGSE lesions in Taiwanese patients. Thirty-four TUGSE cases were retrieved from the files of the Department of Oral Pathology and Oral Diagnosis, National Taiwan University Hospital from 2003 to 2009. Their clinical data and histopathological features were examined, collected, and analyzed. The study group included 22 male and 12 female patients (64.7% and 35.3%, respectively) with oral TUGSE. The mean age of the patients was 49 years (range, 8 to 80 years). The most common site for oral TUGSE lesions was the tongue (23 cases, 67.6%), followed by the buccal mucosa (6 cases, 17.6%), retromolar area (2 cases, 5.9%), floor of the mouth and lingual sulcus (2 cases, 5.9%), and lip (1 case, 3.0%). For 23 tongue cases, 19 occurred on the dorsum and the tip (82.6%) and 4 on the ventral surface (17.4%). Of the 34 oral TUGSE lesions, 13 (38.2%) had a mild, 11 (32.4%) a moderate, and 10 (29.4%) a severe eosinophilic infiltrate. Oral TUGSE lesions occur more frequently on the dorsal surface and the tip of the tongue and in male patients between 41 and 60 years of age. The eosinophilic infiltrates in oral TUGSE lesions show a scattered or clustered pattern, and their density varies from case to case. Oral TUGSE is a self-limiting lesion, and aggressive surgical treatment is usually not required. Copyright © 2013. Published by Elsevier B.V.

    Tabernanthe iboga belongs to the Apocynaceae family. In this study, we report the case of a 37-year-old black male working as a security agent in Paris and found dead naked on the beach in Gabon after consumption of iboga. Autopsy revealed a drowning fatality and a myocardial abnormality (myocardial bridging). Samples of blood, urine, bile, gastric content, liver, lungs, vitreous, spleen and hair were taken. Biological fluids were liquid-liquid extracted with saturated NH4Cl pH 9.5 and methylene chloride/isopropanol (95/5, v/v) in presence of clonazepam-d(4), used as internal standard. After decontamination with dichloromethane, hair was cut into small pieces then sonicated for 2h in saturated NH4Cl pH 9.5 before extraction by methylene chloride/isopropanol (95/5, v/v). After evaporation the residues were reconstituted in methanol/ACN/formate buffer pH 3, from which 10 microL were injected into an ODB Uptisphere C(18) column (150 mm x 2.1mm, 5 microm) and eluted with a gradient of acetonitrile and formate buffer delivered at a flow rate of 200 microL/min. A Quantum Ultra triple-quadrupole mass spectrometer was used for analyses. Ionization was achieved using electrospray in the positive ionization mode (ESI). For each compound, detection was related to three daughter ions (ibogaine: m/z 311.4-->122.1, 174.1 and 188.1; noribogaine: m/z 297.4-->122.1, 159.1 and 160.1; clonazepam-d(4): m/z 319.9-->218.1, 245.1 and 274.1). Ibogaine and noribogaine were detected in all autopsy samples. Hair segmentation was not possible as hair was very short and frizzy. Concentrations of 1.2 and 2.5 ng/mg, respectively were detected. Neither other licit or illicit drugs nor alcohol were found. The presence of ibogaine and noribogaine in all autopsy samples was consistent with the recent absorption of Tabernanthe iboga, which was assumed to be responsible of the drowning fatality. The history of exposure, regarding hair analysis, is discussed. LC-MS/MS appears to be the best method for

    Oral case presentation is an essential skill in clinical practice that is decidedly varied and understudied in teaching curricula. We developed a curriculum to improve oral case presentation skills in medical students. As part of an internal medicine clerkship, students receive instruction in the elements of a good oral case presentation and then present a real-world case in front of a video camera. Each student self-evaluates his/her presentation and receives evaluations from his/her peers. We expect peer and self-evaluation to be meaningful tools for developing skills in oral presentation. We hope to not only improve the quality of oral case presentations by students but also to reduce the time burden on faculty.

Following an initial pilot study, five randomized, double-blind studies assessed the effectiveness of the oral marine supplement for promoting hair growth. Each study was approved by one or more institutional review boards. Together, these studies demonstrated the ability of oral marine supplements to increase the growth of terminal and vellus hairs, increase the diameter of terminal and vellus hairs, and decrease hair loss. This product is beneficial for men as well as women. A dietary supplement containing a marine complex and other natural ingredients can safely and effectively promote hair growth and decrease hair shedding in women and men with thinning hair. © 2017 Wiley Periodicals, Inc.

  18. Two Unusual Cases of Oral Lichen Planus Arising After Oral Squamous Cell Carcinoma: Can Oral Cancer Trigger Autoimmunity?

    Gissi, Davide Bartolomeo; Asioli, Sofia; Gabusi, Andrea

    2017-08-01

    Autoimmune diseases occur when the immune system fails to recognize self-antigens expressed on the body's own cells and attacks them. Oral lichen planus (OLP) is a chronic autoimmune mucocutaneous disease of the oral cavity characterized by white/red lesions. Considered a potentially malignant disorder, OLP evolution into oral squamous cell carcinoma (OSCC) is still a matter of debate. While chronic autoimmune inflammation is considered a potential risk factor for malignant transformation in many solid tumors, the opposite idea that cancer may trigger autoimmune responses remains controversial. We describe 2 patients who developed lesions clinically suggestive of OLP with histological evidence of lichenoid infiltration some time after OSCC removal, even in areas far from the neoplastic site. Neither patient had OLP before the diagnosis of OSCC, or reported exposure to OLP-associated etiologic factors, and neither. experienced tumor recurrence during follow-up. Our findings suggest that oral cancer remission may be linked to OLP development, but further studies are necessary to unveil the underlying mechanisms and possible prognostic implications.

    Hair in the pilonidal sinus is not growing within the sinus cavity, as hair follicles are not present there. Not few pilonidal patients do not have intergluteal hair, which is said to be the causative agent of folliculitis and pilonidal genesis. So, what is the real source of the hair forming the typical pilonidal hair nest? A trifold approach was used: First, axial hair strength testing of pilonidal hair and body hair harvested from head, lower back (glabella sacralis), and cranial third of intergluteal fold. Hair strength match was compared clinically. Second, comparative morphological examination by expert forensic biologist of hair from sinus and dorsal body hair. Third, statistical Bayesian classification of every single sinus hair based on its strength was done to determine the most probable region of origin. Using clinical hair strength comparison, in 13/20 patients, head hair is the stiffest hair, followed by intergluteal hair. Only in 6/20 patients, this is the case with hair from the glabella sacralis. According to comparative morphological comparison, a minimum of 5 of 13 hair nests with possible hair allocation examined contain hair from the occiput. In 5/18 nests, hair could not be determined to a specific location though. Statistical classification with correction for multiple testing shows that 2 nests have hair samples that are at least 100 times more probable to originate from head or lower back than from intergluteal fold. We saw our null hypothesis that "hair in the sinus cavity is from the intergluteal region" rejected by each of three different approaches. There is strong evidence that occipital hair is present regularly in pilonidal sinus nests. We should start thinking of occipital hair as an important hair source for the development of the pilonidal hair nest.

    2008-03-01

    Full Text Available Hair transplantation is a surgical method of hair restoration. Physician qualification : The physician performing hair transplantation should have completed post graduation training in dermatology; he should have adequate background training in dermatosurgery at a centre that provides education training in cutaneous surgery. In addition, he should obtain specific hair transplantation training or experience at the surgical table(hands on under the supervision of an appropriately trained and experienced hair transplant surgeon. In addition to the surgical technique, training should include instruction in local anesthesia and emergency resuscitation and care. Facility : Hair transplantation can be performed safely in an outpatient day case dermatosurgical facility. The day case theatre should be equipped with facilities for monitoring and handling emergencies. A plan for handling emergencies should be in place and all nursing staff should be familiar with the emergency plan. It is preferable, but not mandatory to have a standby anesthetist. Indication for hair transplantation is pattern hair loss in males and also in females. In female pattern hair loss, investigations to rule out any underlying cause for hair loss such as anemia and thyroid deficiency should be carried out. Hair transplantation can also be performed in selected cases of scarring alopecia, eyebrows and eye lashes, by experienced surgeons. Preoperative counseling and informed consent :Detailed consent form listing details about the procedure and possible complications should be signed by the patient. The consent form should specifically state the limitations of the procedure and if more procedures are needed for proper results, it should be clearly mentioned. Patient should be provided with adequate opportunity to seek information through brochures, computer presentations, and personal discussions. Need for concomitant medical therapy should be emphasized. Patients should understand

    A few anecdotal case reports demonstrated that tofacitinib improved nail changes associated with AA. To investigate nail changes in patients with AA treated with tofacitinib and evaluate the relationship between nail and hair responses to tofacitinib. This is a retrospective study of 33 adult patients with moderate-to-severe AA treated with oral tofacitinib monotherapy for at least 4 months. Fifteen patients had nail involvement and demonstrated more severe hair loss than those without nail involvement (p = .040). However, there was no significant difference in hair regrowth between two groups. Of 15 patients with nail involvement, 11 (73.3%) showed improvement regardless of type of nail change; the first improvement was observed at a median of 5 months (range, 1-11) after administration. Nail improvement was associated with neither initial severity of hair loss nor hair response to tofacitinib. Nail improvement tended to occur later than hair regrowth. Oral tofacitinib monotherapy improves nail involvement associated with AA. Nail involvement is not a poor prognosis factor in hair regrowth with tofacitinib treatment and there is no evident relationship between nail and hair responses.

    Lysergic acid diethylamide (LSD) is a potent hallucinogen, active at very low dosage and its determination in body fluids in a forensic context may present some difficulties, even more so in hair. A dedicated liquid chromatography-electrospray-tandem mass spectrometry (LC-ES-MS/MS) assay in hair was used to document the case of a 24-year-old man found dead after a party. Briefly, after a decontamination step, a 50mg sample of the victim's pubic hair was cut into small pieces (LSD. A LSD concentration of 0.66pg/mg of pubic hair was observed. However, this result remains difficult to interpret owing to the concomitant LSD presence in the victim's post mortem blood and urine, the lack of previously reported LSD concentrations in hair, and the absence of data about LSD incorporation and stability in pubic hair.

    Oral lichen planus (OLP) may show depositions of immunoglobulins and complement components in oral mucosal basement membrane zone (BMZ) in direct immunofluorescence, although these finding are not frequently seen. We collected and examined ten cases of severe OLP showing granular C3 deposition in BMZ. In addition to clinical, histopathological and direct immunofluorescence assessments, we performed various immune-serological tests, including indirect immunofluorescence of normal human skin and 1M NaCl-split skin, immunoblotting of normal human epidermal and dermal extracts, recombinant proteins of BP180 NC16a and C-terminal domains, concentrated culture supernatant of HaCaT cells and purified human laminin-332, and enzyme-linked immunosorbent assays for BP230 and BP180. Direct immunofluorescence showed C3 deposition in BMZ exclusively of granular pattern in 7 cases and of both granular and linear patterns in 3 cases. The 10 cases showed no positive reactivity for either IgG or IgA antibodies in any immuno-serological tests. Detailed analyses of clinical, histopathological and immunological findings revealed striking female prevalence, although other parameters were in general characteristic of OLP. Granular C3 deposition in oral BMZ may be one of the characteristic features of severe OLP, although mechanisms for C3 deposition and its pathogenic role in OLP are currently unknown.

    The present work assesses human exposure to pesticides in vegetable-producing areas in Burkina Faso, using hair as an indicator. The study design includes a comparison between operators who are occupationally exposed while working in the fields and a reference population (i.e. not occupationally exposed) to evaluate both occupational and indirect exposures. Hair samples from volunteers (n=101) were positive for 17 pesticides (38 analyzed). Acetamiprid, desethylatrazine, carbofuran, and deltamethrin were detected for the first time in field samples. With a maximum of 9 residues per sample, pesticide exposure was ubiquitous in both populations. Contamination by acetamiprid, cypermethrin, and lambda-cyhalothrin (used in vegetable production) prevailed in operator samples. For other pesticides, such as imidacloprid and deltamethrin, no significant difference was found. This indicates a potentially large environmental exposure (dietary intake or atmospheric contamination) or the prevalence of other contamination sources. The present findings are concerning, as detected levels are globally higher than those previously reported, and indicate exposure to endocrine disrupting chemicals and probable carcinogens. Hair was found to be a suitable matrix for biomonitoring human exposure to pesticides and assessing dominant factors (i.e. sex, age, and protective equipment) in subgroups, as well as identifying geographical contamination patterns.

    This study sets out to develop a questionnaire on willingness to communicate (WTC) orally specific to English as a Foreign Language setting. It also aims to investigate the effect of three independent variables of interlocutor, age and gender on the same construct of WTC orally. Exploratory factor analysis resulted in three dimensions to WTC, namely WTC with teacher, with classmate, and stranger. Also Cronbach's alpha of .86 indicated a high internal consistency. Mixed between-within subjects analysis of variance was used to assess the impact of interlocutors, age and gender on participants' WTC across the three WTC subscale scores. The results showed no interaction effect between any of pairs of variables but the main effect of interlocutor on WTC orally. The results are discussed in the context of language teaching and some pedagogical implications are suggested.

    Full Text Available Laser has been used efficiently for treatment of oral lichen planus, leukoplakia, aphthous ulcers and oral manifestations of HIV. Two cases of recalcitrant oral pemphigus vulgaris that were successfully treated with CO 2 laser are described. The patients had been treated by a dermatologist with pulse therapy of methyl prednisolone and cyclophosphamide over a period of 6 to 8 months, but the clinical course was characterized by episodes of painful flare-ups and nonresponsiveness. The patients were extremely uncomfortable with recurrent oral lesions. CO 2 laser at low power was used to irradiate the lesions. It was shown to be effective in relieving pain and healing of lesions, with nonrecurrence. To the best of our knowledge, this is the first case report of such a treatment of oral pemphigus vulgaris. Further clinical studies are warranted to confirm efficacy and to optimize the treatment protocol.

    Full Text Available Primary oral melanoma is a rare neoplasm of melanocytic origin, accounting for 0.5% of all oral malignancies. The "chameleonic" presentation of a mainly asymptomatic condition, rarity of this lesion, poor prognosis, and the necessity of a highly specialized treatment are factors that should be seriously considered by the involved health provider. Here is a case report presenting a malignant melanoma of oral mucosa in 48-year-old male patient on maxillary gingiva. The lesion was removed by partial maxillectomy and patient is disease free after 11 months of regular followup. This case provides an example of how dental clinicians play a major role in the identification of pigmented lesions of oral cavity and also emphasize on the fact that any pigmented lesion detected in the oral cavity may exhibit potential growth and should be submitted to biopsy to exclude malignancy.

    2014-11-01

    The role of qat chewing, tobacco (shammah) dipping, smoking, alcohol drinking, and oral viral infection as risk factors for oral squamous cell carcinoma (OSCC) in Yemen was assessed. A total of 60 cases of OSCC and 120 age- and gender-matched controls were analyzed with respect to demographic data, history of oral habits, and the presence of human papillomavirus (HPV)-16, HPV-18, or Epstein-Barr virus (EBV) as determined by Taqman quantitative polymerase chain reaction. Logistic regression analysis was used to identify independent predictors of the disease. Shammah use was the only risk factor for OSCC, with an odds ratio of 12.6 (CI, 3.3-48.2) and 39 (CI, 14-105) for the ex-users and current users, respectively. The association of shammah use alone with OSCC exceeded that of shammah use in combination with qat chewing, smoking, or both. EBV infection, smoking, and qat chewing showed no association with OSCC, while neither HPV-16 nor HPV-18 were detected in any sample. Shammah use is a major risk factor for oral cancer in Yemen.

    This study aims to develop a simple dietary score to comprehensively evaluate the role of diet in the risk of oral cancer. A case-control study including 930 oral cancer cases and 2667 frequency-matched controls was performed in Fujian, China. Unconditional logistic regression model was used to estimate the effects of dietary factors on oral cancer. After adjustment for potential confounders, less intake of domestic meat (oral cancer. Then these variables were incorporated to establish dietary risk score. Assessed by the receiver operating characteristic curve, the score showed a satisfactory discriminatory capacity, with an area under the curve of 0.682 (95% CI: 0.662-0.702). Moreover, the score was positively associated with the risk of oral cancer as quartiles, and the association was apparently stronger in tobacco smokers or alcohol drinkers. Additionally, there were significant multiplicative interactions between the score and tobacco smoking or alcohol drinking for oral cancer. In the present study, a convenient dietary score with satisfactory discriminatory capacity was developed to assess the collected effect of dietary factors on oral cancer, which could provide a new strategy for the prevention of oral cancer through changing in dietary habits.

    Τo describe the clinicopathological features of 26 oral lymphoepithelial cysts (LECs) and review the literature. Twenty-six cases of oral LECs diagnosed during a 37-year period were retrospectively collected. The patients' gender and age, as well as the main clinical features of the cysts were retrieved from the requisition forms. The main microscopic features were recorded after reevaluation of all cases. Pubmed and Google Scholar electronic databases were searched with the key word "oral LEC". Inclusion criteria were the microscopic confirmation of LEC diagnosis and the report at least two of three main clinical features (gender, age and cyst's location). The 26 oral LECs represented 0.08% of 31,564 biopsies accessioned during the study period. They affected 25 patients, 14 females and 11 males with a mean age of 33.04±9.81 years. They appeared as smooth (92%) nodules, with soft (24%) or firm (76%) consistency and normal (28%), yellow to normal (20%), yellow (32%) or white (20%) hue, in the tongue (69.23%) or the floor of mouth (30.77%). They were covered by parakeratinized squamous (92.31%) or non-keratinized (7.69%) epithelium and contained desquamated epithelial cells, amorphous eosinophilic material and/or inflammatory cells (100%). The lymphoid tissue surrounded the cystic cavity partially (34.62%) or completely (65.38%), often in a follicular pattern with prominent germinal centers (53.85%). Literature review yielded 316 cases of oral LECs derived from 25 case reports, 3 case studies/retrospective studies with detailed information for each case and 7 studies with summarized data. Oral LEC is a pathologic entity with discrete clinical presentation that is, however, commonly misdiagnosed in clinical practice as other, mostly benign, entities. Its pathogenesis remains obscure, as its clinicopathologic features are consistent with both theories suggested up to date.

    Full Text Available Abstract Introduction Deposition of amyloid fibrils derived from circulating acute-phase reactant serum amyloid A protein causes systemic amyloidosis, a serious inflammatory disorder. We document a male patient who developed reactive amyloidosis (AA type, most likely secondary to his long standing periodontitis. Case presentation A 67-year-old Turkish man complained of pain in his oral cavity (burning mouth especially on the tongue, and had difficulty chewing and swallowing foods. A careful dental/periodontal examination was performed, including assessment of plaque, gingival condition and periodontal probing depths on all his remaining teeth. Prosthetic rehabilitation was provided three months after the completion of his periodontal and surgical therapy. The concentration of serum inflammatory markers including erythrocyte sedimentation rate, white blood cell count, fibrinogen and high sensitive C-reactive protein were measured at baseline, at the second and sixth weeks, and at three and six months after the periodontal and surgical therapy. Conclusions Oral examination revealed a few papules on the dorsum of the tongue with two slightly painful, small ulcers, localized on the vestibule of the mouth. The mean probing depth was 9.10 ± 0.84 mm. Biopsies of the tongue, buccal mucosa and retromolar trigone were performed and amyloid deposits were found. The serum inflammatory markers improved more dramatically at the second week of periodontal therapy than any other time intervals. Amyloidosis may manifest as periodontal destruction that leads to severe chronic periodontitis. Proper periodontal treatment may alleviate systemic inflammatory mediators caused by the amyloidosis.

    2009-03-01

    Full Text Available Abstract Background Male pattern baldness (MPB, an observable trait, has been reported to be associated with various diseases, such as prostate cancer and cardiovascular disease. Oral sulfur-containing gases have also been suggested to be useful as markers of systemic health condition. However, there are no known reports regarding the associations among MPB, and oral sulfur-containing gases, and systemic health conditions in males. Methods We studied 170 male subjects aged either 60 or 65 years old. The degree of MPB was assessed using the Norwood-Hamilton Baldness scale. Oral sulfur-containing gases were measured using a compact-designed device. All subjects completed physical and laboratory blood examinations, a face-to-face medical questionnaire, and an oral examination. Results There were significant differences between the levels of CH3SCH3 and baldness patterns, independent of age. When we analyzed whether the association was linked to systemic health condition, a strong significant association was observed between the level of CH3SCH3 and severe MPB in subjects with gastrointestinal diseases, hypertension, and hypercholesterolemia. Conclusion These results suggest that MPB is associated with the level of CH3SCH3, a sulfur-containing gas that causes oral malodor, in elderly Japanese males. Further, the association was intensified by the existence of gastrointestinal tract and metabolic disorders.

  9. Interpretation of Cannabis Findings in the Hair of Very Young Children: Mission Impossible.

    Hair has been suggested since the middle of the 90's to be a suitable matrix to document repetitive exposure to cannabis. Because it is possible to detect Δ9-tetrahydrocannabinol (THC), cannabinol (CBN) and cannabidiol (CBD) in cannabis smoke, the identification of the metabolite, 11-nor-Δ9-tetrahydrocannabinol carboxylic acid (THC-COOH) has been considered to allow the discrimination of active use. Although the identification of an active compound in a child's hair shows contamination of the local environment, it is a challenge to discriminate between hair incorporation after ingestion or inhalation and environmental external deposition from dust, smoke, or even contaminated surfaces by hand contact. However, it is particularly important in case of children to correctly interpret the data, particularly for a realistic assessment of the health risk. We present here a series of hair tests for cannabis where the interpretation was almost impossible to establish. Hair specimens were collected during the autopsy of the 12 children, aged 2 to 24 months, either deceased from shaken baby syndrome (SBS, n=4), mechanic asphyxia (MA, n=1) or sudden infant death (SID, n=7) during January 2015 to April 2017. After decontamination, the hair specimens were tested for THC, CBN and CBD and THC-COOH. The whole length of hair was submitted to analysis. The amount of hair from children can be as low as 8 mg. This may affect the limit of quantitation of all drugs, but particularly THC-COOH. Eight from twelve hair tests were positive for cannabis markers, i.e. THC (39 to 1890 pg/mg, n=8), CBN (cannabis use during pregnancy), oral cannabis administration by the parents to achieve sedation, close contact to cannabis consumers (hands, bedding, dishes) and inhalation of side-stream smoke. Over-interpreting cannabis findings in hair can have very serious legal implication in child protection cases. Practicing scientists have the responsibility to inform the child protection authorities

    2017-01-01

    Full Text Available Background. Steatocystoma multiplex (SM and eruptive vellus hair cysts (EVHC are uncommon benign tumors of the pilosebaceous unit. Both SM and EVHC are characterized by smooth, asymptomatic papules or nodules, most commonly presenting on the chest, limbs, and abdomen. Most cases of SM and EVHC are sporadic, although less common autosomal dominant inherited forms have been reported. Main Observation. In this report we present two cases of cutaneous cysts exhibiting characteristics of either SM or EVHC. Both patients presented with numerous 1-2 mm asymptomatic papules and responded well to surgical expression by incision and drainage (I&D. Conclusion. SM and EVHC are similar in clinical presentation and management. Previously reported “hybrid-type” tumors present strong evidence for a relationship between the two lesions pathologically. Due to potential similarity of EVHC and SM cyst contents, I&D and subsequent microscopic examination cannot definitely differentiate between EVHC, SM, and hybrid cysts.

    Full Text Available Oral melanocytic nevi are localized developmental tissue malformations of nevus cells in the oral mucosa. Relatively rare in occurrence compared to their dermal counterparts, considerable debate exists in the literature related to their origin, development and maturation, and their relationship to oral melanocytes.We report two cases of oral melanocytic nevi with classical clinical presentation. The histopathology was consistent with the known patterns of oral melanocytic nevi. Special stains such as Masson Fontana, further substantiated the observation. S-100 and HMB-45 were applied to immunohistochemically elaborate the cell population. Interestingly two distinct cell populations were detected in the lesions. "Type A" cells in the center of the lesion were S-100 positive, indicating a neural origin and immaturity in development, while peripheral "type B" cells stained positive with HMB-45, indicating melanocytic origin and mature development.

  12. Frontier in hair loss and trichoscopy: A review

    Ebtisam Elghblawi

    2016-07-01

    Full Text Available Skin surfaces have always been examined using dermoscopy, a familiar tool which is useful to magnify and examine skin especially in cases of pigmented skin lesions. However, to examine the hair and scalp, a practical tool called trichoscopy has surfaced recently and has proven to be handy and functional in diagnosing most hair-related diseases. It is also referred to as dermoscopy of the hair and the scalp. It can aid in assessing active diseases in the scalp and hair, such as yellow dots, dystrophic hairs, cadaverized black dots, white dots, and exclamation mark hairs – all of which denote specific criteria for hair diseases. Trichoscopy is a very newly developed non-invasive technique for hair image analysis. It permits non-invasive visualization of hair shafts at higher intensification (about ×70 and ×100 and enables measurement of hair shaft width without the need for removing hair for diagnostic reasons. Moreover, it helps in vivo visualization of the epidermal portion of hair follicles and perifollicular epidermis (orifices. Consequently, it is valuable as it permits the inspection of structures that are otherwise not seen by the naked eye. Trichoscopy is the new frontier for the diagnosis of hair and scalp disease. Nowadays, a trichoscope is considered a must for dermatologists and it is a hot topic in the treatment of hair diseases. There is pooled evidence that the utilization of trichoscopy in the clinical setting for evaluating hair disorders can improve its diagnostic capability beyond simple clinical scrutiny. Trichoscopy can identify both hair shaft and hair opening abnormalities without the need for hair sampling, as well as distinguish between different scalp and hair diseases. Furthermore, it can give easy and quick evaluation of the hair with a follow-up to determine progress and prognosis of the disease with photos. It can also aid in some genetic hair shaft dystrophies such as trichorrhexis nodosa, trichorrhexis

La sífilis secundaria cursa con manifestaciones mucocutáneas características y eventual sintomatología general. La presentación clínica de nuestros dos pacientes es singular ya que solo poseían lesiones en la cavidad oral. La respuesta al tratamiento instaurado fue buena.Syphilis is a human infectious disease caused by the bacterium Treponema pallidum. The disease is transmitted by direct contact with a lesion during the primary or secondary stages, in utero by the transplacental route, or during delivery as the baby passes through an infected canal. The bacterium may infect any organ, causing an infinite number of clinical presentations. Secondary syphilis is characterized by mucocutaneous lesions, a flulike syndrome, and generalized adenopathy. Hepatosplenomegaly may be present. The oral mucosa is the second most frequent site of luetic lesions; the genital areas are the most frequent. In the oral cavity, the most characteristic lesion is a whitish mucosal patch, normally located on the lips, tongue, or palate, which is extremely contagious. The differential diagnosis of this lesion may include oral squamous carcinoma, leukoplakia, candidosis, lichen planus, and hairy oral leukoplakia. Definitive diagnosis is based on clinical information and completed by laboratory examinations even the biopsy can help us. With the diagnosis of secondary syphilis treatment with penicillin G benzathine must be started.

    2015-03-01

    Full Text Available Summary: Fine hairs of the head and nape areas have been used as donor sources in eyelash transplantation but are straight, coarse, and grow rapidly, requiring frequent eyelash maintenance. This is the first reported case of eyelash transplantation by follicular unit extraction using leg hair as a donor source; findings were compared with that of another patient who underwent a similar procedure with donor hairs from the nape area. Although both patients reported marked improvement in fullness of eyelashes within 3 months postsurgery, the transplanted leg hair eyelashes required less frequent trimming (every 5–6 weeks compared with nape hair eyelashes (every 2–3 weeks. Additionally, in leg hair eyelashes, the need for perming to sustain a natural looking eyelash curl was eliminated. Eyelash transplantation using leg donor hair in hirsute women may result in good cosmetic outcomes and require less maintenance compared with nape donor hair.

    Full Text Available Introduction: Due to hormonal stimulation during puberty, changes occur in hair type and distribution. In both sexes, body and facial unwanted hair may have a negative psychological impact on the teenager. There are several available methods of hair removal, but the choice of the most suitable one for each individual can raise doubts. Objective: To review the main methods of hair removal and clarify their indications, advantages and disadvantages. Development: There are several removal methods currently available. Shaving and depilation with chemicals products are temporary methods, that need frequent repetition, because hair removal is next to the cutaneous surface. The epilating methods in which there is full hair extraction include: epilation with wax, thread, tweezers, epilating machines, laser, intense pulsed light, and electrolysis. Conclusions: The age of beginning hair removal and the method choice must be individualized and take into consideration the skin and hair type, location, dermatological and endocrine problems, removal frequency, cost and personal preferences.

    This study examines the association between the incidence of oral cancer in India and oral hygiene habits, diet, chewing and smoking tobacco, and drinking alcohol. We also assessed the effects of oral hygiene habits with oral cancer risk among chewers versus never chewers. A hospital-based case-control study was conducted in Pune, India, based on face-to-face interviews, anthropometry, and intra-oral examinations conducted for 187 oral cancer cases and 240 controls. Poor oral hygiene score was associated with a significant risk of oral cancer (adjusted OR=6.98; 95%CI 3.72-13.05). When stratified by tobacco-chewing habit, the poor oral hygiene score was a significant risk factor only among ever tobacco chewers (adjusted OR=14.74; 95%CI 6.49-33.46) compared with never chewers (adjusted OR=0.71; 95%CI 0.14-3.63). Dental check-ups only at the time of pain by ever-chewers with poor oral hygiene was associated with an elevated risk (adjusted OR=4.22; 95%CI 2.44-7.29), while consumption of green, yellow, and cruciferous vegetables and citrus fruits was protective. A linear dose-response association was observed between oral cancer and chewing tobacco in terms of age at initiation, duration, and frequency of chewing per day (P25 years (adjusted OR=2.31; 95%CI 1.14-4.71) elevated the risk of oral cancer. Good oral hygiene habits - as characterized by healthy gums, brushing more than once daily, use of toothpaste, annual dental check-ups, and a minimal number of missing teeth - can reduce the risk of oral cancer significantly. In addition to refraining from chewing/smoking tobacco, a diet adequate in fruits and vegetables may protect against the disease. Copyright © 2017 Elsevier Ltd. All rights reserved.

  1. Extensive Myiasis infestation associated with Oral Squamous Cell Carcinoma: Report of two cases

    Directory of Open Access Journals (Sweden)

    Sudharani Biradar

    2015-01-01

    Full Text Available Myiasis is the condition of infestation of the body by fly larvae (maggots. The deposited eggs develop into larvae, which penetrate deep structures causing adjacent tissue destruction. It is an uncommon clinical condition, being more frequent in tropical countries and hot climate regions, and associated with poor hygiene, suppurative oral lesions, alcoholism and senility. The diagnosis of Myiasis is basically made by the presence of larvae. The reported cases of oral Myiasis associated with oral cancer in the literature are few. This paper reports two cases of oral and maxillofacial Myiasis involving larvae in patients with squamous cell carcinoma in adult males. The condition was managed by manual removal of the larvae, one by one, with the help of forceps and subsequent management through proper health care.

    Uncombable hair syndrome (UHS), also known as "spun glass hair syndrome," "pili trianguli et canaliculi," or "cheveux incoiffables" is a rare anomaly of the hair shaft that occurs in children and improves with age. UHS is characterized by dry, frizzy, spangly, and often fair hair that is resistant...... in the majority of UHS case subjects. The two enzymes PADI3 and TGM3, responsible for posttranslational protein modifications, and their target structural protein TCHH are all involved in hair shaft formation. Elucidation of the molecular outcomes of the disease-causing mutations by cell culture experiments...... and tridimensional protein models demonstrated clear differences in the structural organization and activity of mutant and wild-type proteins. Scanning electron microscopy observations revealed morphological alterations in hair coat of Padi3 knockout mice. All together, these findings elucidate the molecular genetic...

    Full Text Available Certain dipteran flies larvae causing invasion of the tissues and organs of the humans or other vertebrates are called as myiasis, which feed on hosts dead or living tissues. It is well documented in the skin and hot climate regions; underdeveloped countries are affected more commonly. Oral cavity is affected rarely and it can be secondary to serious medical conditions. Poor oral hygiene, alcoholism, senility, or suppurating lesions can be associated with the oral myiasis. Inflammatory and allergic reactions are the commonest clinical manifestations of the disease. In the present case, gingiva of maxillary anterior region was affected by larval infection in a 13-year-old mentally retarded patient.

    PET/CT is a new imaging technology that combines high-quality Position Emission Tomography (PET) and Computed Tomography (CT). This imaging provides simultaneous anatomical and metabolic information. Therefore PET/CT is useful diagnostic modality for early detection og malignant tumor, accurate at aging, decision on therapeutic plan, monitoring response to therapy and rapid detection of recurrence. We report oral and maxillofacial cancers diagnosed by using PET/CT and the usefulness of PET/CT in the evaluation of postoperative recurrence.

  6. Cellular Angiofibroma of Oral Mucosa: Report of Two Cases

    Science.gov (United States)

    2009-01-01

    Cellular angiofibroma is a benign vascular neoplasm that typically arises in the vulva, perineal, and paratesticular region. Microscopically the lesions exhibit multiple small, non-dilated capillary channels, many of which contain erythrocytes. The endothelial lining cells are prominent, with monomorphic oval nuclei. Interposed among the vessels are both delicate and mature collagen fibers with fibroblastic hypercellularity that is variable in older lesions where sclerosis is prominent. The lesions usually do not recur following simple excision. Recent evidence indicates that cellular angiofibromas may be cytogenetically related to spindle cell lipoma. This represents the first reported instances of cellular angiofibroma in the oral cavity. PMID:19644547

    2005-04-01

    Full Text Available Abstract Background Cannabis is the most commonly used illegal drug and its therapeutic aspects have a growing interest. Short-term psychotic reactions have been described but not clearly with synthetic oral THC, especially in occasional users. Case presentations We report two cases of healthy subjects who were occasional but regular cannabis users without psychiatric history who developed transient psychotic symptoms (depersonalization, paranoid feelings and derealisation following oral administration of cannabis. In contrast to most other case reports where circumstances and blood concentrations are unknown, the two cases reported here happened under experimental conditions with all subjects negative for cannabis, opiates, amphetamines, cocaine, benzodiazepines and alcohol, and therefore the ingested dose, the time-events of effects on behavior and performance as well as the cannabinoid blood levels were documented. Conclusion While the oral route of administration achieves only limited blood concentrations, significant psychotic reactions may occur.

  13. Serum Biotin Levels in Women Complaining of Hair Loss.

    Science.gov (United States)

    Trüeb, Ralph M

    2016-01-01

    Biotin is a coenzyme for carboxylase enzymes that assist various metabolic reactions involved in fatty acid synthesis, branched-chain amino acid catabolism, and gluconeogenesis important for maintenance of healthy skin and hair. Due to its availability, affordability, and effective marketing for this purpose, biotin is a popular nutritional supplement for treatment of hair loss. However, there are little data on the frequency of biotin deficiency in patients complaining of hair loss and on the value of oral biotin for treatment of hair loss that is not due to an inborn error of biotin metabolism or deficiency. The aim of this study was to determine the frequency and significance of biotin deficiency in women complaining of hair loss. Biotin deficiency was found in 38% of women complaining of hair loss. Of those showing diffuse telogen effluvium in trichograms (24%), 35% had evidence of associated seborrheic-like dermatitis. About 11% of patients with biotin deficiency had a positive personal history for risk factors for biotin deficiency. The custom of treating women complaining of hair loss in an indiscriminate manner with oral biotin supplementation is to be rejected, unless biotin deficiency and its significance for the complaint of hair loss in an individual has been demonstrated on the basis of a careful patient history, clinical examination, determination of serum biotin levels, and exclusion of alternative factors responsible for hair loss.

  14. From Hair in India to Hair India.

    2017-01-01

    In all cultures, human hair and hairdo have been a powerful metaphor. Tracing back the importance and significance of human hair to the dawn of civilization on the Indian subcontinent, we find that all the Vedic gods are depicted as having uncut hair in mythological stories as well as in legendary pictures. The same is true of the Hindu avatars, and the epic heroes of the Ramayana, and the Mahabharata. Finally, there are a number of hair peculiarities in India pertinent to the creed and religious practices of the Hindu, the Jain, and the Sikh. Shiva Nataraja is a depiction of the Hindu God Shiva as the cosmic dancer who performs his divine dance as creator, preserver, and destroyer of the universe and conveys the Indian conception of the never-ending cycle of time. The same principle manifests in the hair cycle, in which perpetual cycles of growth, regression, and resting underly the growth and shedding of hair. Finally, The Hair Research Society of India was founded as a nonprofit organisation dedicated to research and education in the science of hair. Notably, the HRSI reached milestones in the journey of academic pursuit with the launch of the International Journal of Trichology, and with the establishment of the Hair India conference. Ultimately, the society aims at saving the public from being taken for a ride by quackery, and at creating the awareness that the science of hair represents a subspecialty of Dermatology. In analogy again, the dwarf on which the Nataraja dances represents the demon of egotism, and thus symbolizes Shiva's, respectively, the HRSI's victory over ignorance.

    The illegal use of formalin (commercial formaldehyde) in cosmetic products harms the health of individuals exposed to this substance. Over the last years, the commercial availability of these products, especially those containing irregular dosage of formaldehyde, has increased in Brazil. This work analyzes some products for hair treatment available in the Brazilian market and verifies their safety. The adopted analytical methodology involved sample derivatization with 2,4-dinitrophenylhydrazine, followed by high-performance liquid chromatography with ultraviolet detection (UV-VIS) at λ = 365 nm. The limit of quantification is 2.5 × 10 -3% w/w, and the recovery tests were around 93%. Some of the samples contained high and illegal formaldehyde levels ranging from 9% to 19% (w/w) and others presented suitable concentrations of the analyte. On the basis of the results, this work discusses the efficiency and practicality of this analytical method for forensic purposes. © 2016 American Academy of Forensic Sciences.

    Full Text Available Introduction: A cleft lip with or without a cleft palate is one of the major congenital anomalies observed in newborns. This study explored the risk factors for oral clefts in Gorgan, Northern Iran.  Materials and Methods: This hospital-based case-control study was performed in three hospitals in Gorgan, Northern Iran between April 2006 and December 2009. The case group contained 33 newborns with oral clefts and the control group contained 63 healthy newborns. Clinical and demographic factors, including date of birth, gender of the newborns, type of oral cleft, consanguinity of the parents, parental ethnicity, and the mother's parity, age, education and intake of folic acid were recorded for analysis.  Results: A significant association was found between parity higher than 2 and the risk of an oral cleft (OR= 3.33, CI 95% [1.20, 9.19], P> 0.02. According to ethnicity, the odds ratio for oral clefts was 0.87 in Turkmens compared with Sistani people (CI 95% [0.25, 2.96] and 1.11 in native Fars people compared with Sistani people (CI 95% [0.38, 3.20]. A lack of folic acid consumption was associated with an increased risk of oral clefts but this was not statistically significant (OR = 1.42, CI 95% [0.58, 3.49]. There were no significant associations between sex (OR boy/girl = 0.96, CI 95% [0.41, 2.23], parent familial relations (OR = 1.07, CI 95% [0.43, 2.63], mother's age and oral clefts.  Conclusions:  The results of this study indicate that higher parity is significantly associated with an increased risk of an oral cleft, while Fars ethnicity and a low intake of folic acid increased the incidence of oral clefts but not significantly.

    Safety of the anti-inflammatory drug flurbiprofen is comparable with that of other non-steroidal anti-inflammatory drugs of the propionic acid class, which are commonly associated with gastrointestinal and renal side effects. Here we report a case of a fatal hypersensitivity reaction to an oral spray of flurbiprofen taken for sore throat. A 29-year-old man came to the emergency care unit reporting sore throat with an intense burning sensation associated with fever. Pharyngotonsillitis was diagnosed, and local treatment with oral flurbiprofen spray was prescribed. Immediately after using the spray, the patient experienced a severe reaction characterized by serious dyspnoea, followed by death. The cause of death was heart failure with acute asphyxia from oedema of the glottis. The cause of death was concluded to be hypersensitivity to flurbiprofen spray. Oral propionic acid derivatives have been associated with a relatively high frequency of allergic reactions. However, allergy to flurbiprofen has rarely been documented. Scientific literature reports two relevant cases of hypersensitivity reaction to flurbiprofen: in one case, a patient presented with a maculopapular rash 48 h after having taken oral flurbiprofen followed by angio-oedema and hypotension. In another case, a single oral dose of flurbiprofen caused itching and swelling around the eyes, redness and increased lacrimation. We describe, for the first time, a fatal case of hypersensitivity reaction to flurbiprofen oral spray. Hypersensitivity reactions to flurbiprofen are infrequent; however, health professionals should be aware of potential adverse reactions, even during topical administration as oral spray. © 2013 John Wiley & Sons Ltd.

    2017-02-01

    Full Text Available BACKGROUND AND OBJECTIVE: Genetics, hormone profiles and other physiologic factors can cause hair loss. Medication induced hair loss is an occasional side effect of many psychopharmaceuticals. It can reduce medication compliance if not discovered and treated. We present a 18 year old female with migraine headache who developed hair loss after 3 months of receiving topiramate treatment. CASE REPORT: 18 year old female had been suffering from headache visited in psychiatric clinic. She agreed to a treatment with topiramate (50mg per day for Migraine headache. 3 months later, the patient complained of significant hair loss. Topiramate tapered to 25 mg/day and stopped. Hair loss stopped after topiramate withdrawal. Two weeks after reintroduction of topiramate, hair loss developed again. The medication was stopped and hair loss stopped again. CONCLUSION: Topiramate can cause hair loss. Although the condition is not life-threatening, a decrease in medication compliance can cause recurrence of the underlying disease. It is necessary to ask the patient at visits about it.

    White, non scrapable lesions are commonly seen in the oral cavity. Based on their history and clinical appearance, most of these lesions can be easily diagnosed, but sometimes diagnosis may go wrong. In order to arrive to a confirmative diagnosis, histopathological assessment is needed in many cases, if not all. 1) To find out the prevalence of clinically diagnosed oral white, non scrapable lesions. 2) To find out the prevalence of histopathologically diagnosed oral white, non scrapable lesions. 3) To correlate the clinical and histopathological diagnosis in the above lesions. A total of 100 cases of oral white, non scrapable lesions were included in the study. Based on their history and clinical presentation, clinical provisional diagnosis was made. Then biopsy was done and confirmatory histopathological diagnosis was given and both were correlated. In order to correlate clinical and histopathological diagnosis Discrepancy Index (DI) was calculated for all the cases. Based on clinical diagnosis, there were 59 cases (59%) of leukoplakia, 29 cases (29%) of lichen planus and six cases (6%) of lichenoid reaction; whereas, based on histopathological diagnosis, there were 66 cases (66%) of leukoplakia epithelial hyperplasia and hyperkeratosis (leukoplakia) and 30 cases (30%) of lichen planus. Seventy eight clinically diagnosed cases (78%) correlated with the histopathological diagnosis and 22 cases (22%) did not correlate. The total discrepancy index was 22%. A clinician needs to be aware of oral white, non scrapable lesions. Due to the overlapping of many clinical features in some of these lesions and also due to their malignant potential, a histopathological confirmative diagnosis is recommended.

  2. [Hormones and hair growth].

    Science.gov (United States)

    Trüeb, R M

    2010-06-01

    With respect to the relationship between hormones and hair growth, the role of androgens for androgenetic alopecia (AGA) and hirsutism is best acknowledged. Accordingly, therapeutic strategies that intervene in androgen metabolism have been successfully developed for treatment of these conditions. Clinical observations of hair conditions involving hormones beyond the androgen horizon have determined their role in regulation of hair growth: estrogens, prolactin, thyroid hormone, cortisone, growth hormone (GH), and melatonin. Primary GH resistance is characterized by thin hair, while acromegaly may cause hypertrichosis. Hyperprolactinemia may cause hair loss and hirsutism. Partial synchronization of the hair cycle in anagen during late pregnancy points to an estrogen effect, while aromatase inhibitors cause hair loss. Hair loss in a causal relationship to thyroid disorders is well documented. In contrast to AGA, senescent alopecia affects the hair in a diffuse manner. The question arises, whether the hypothesis that a causal relationship exists between the age-related reduction of circulating hormones and organ function also applies to hair and the aging of hair.

    2018-01-01

    Collagenous fibroma, also known as desmoplastic fibroblastoma, is a rare benign slow growing tumor particularly uncommon in the oral cavity. The aim of this study was to analyze the clinical and histopathological features of an oral collagenous fibroma as well as to compare this data with those reported in an English-literature review. The thirteenth case of collagenous fibroma in the oral cavity and the first to present clinically as a bilateral mass was described. A 48-years-old female patient was referred to a School of Dentistry, complaining about an asymptomatic swelling on the hard palate, lasting around ten years. The intraoral examination revealed two well-defined mass, bilaterally in the hard palate. An excisional biopsy was performed. Microscopically, the connective tissue consisted of dense collagen bundles in which were seen scarcely distributed spindle-shaped to stellate fibroblastic cells. Blood vessels were few, as well as inflammatory cells. Immunohistochemical staining was positive for vimentin, α-smooth muscle actin and factor XIIIa and negative for S-100, CD68, CD34, HHF35, desmin and AE1/AE3. The patient remains disease-free 24 months after excision. In conclusion, oral collagenous fibroma should be included in the differential diagnosis of bilateral sessile nodules in the oral cavity.

    Monilethrix is a rare structural disorder of hair. Characteristic abnormalities in the form of alternating thinning and fusiform thickening are observed in most of hair shafts that we call beaded hair. Macroscopic estimation shows lustreless, dry, rough, fragile hair. Trichological examination usually reveals a considerable percentage of anagenic hair. According to our own experiences and literature data systemic therapy (vitamins) and topical treatment (desquamative ointments) are not effective sufficiently. Spontaneous regression of symptoms often appears with time. Five cases of familial occurrence of monilethrix have been presented.

    2014-11-01

    Hair plays a significant role in body image, and its appearance can be changed relatively easily without resort to surgical procedures. Cosmetics and techniques have therefore been used to change hair appearance since time immemorial. The cosmetics industry has developed efficient products that can be used on healthy hair or act on concomitant diseases of the hair and scalp. Dyes embellish the hair by bleaching or coloring it briefly, for temporary periods of longer duration, or permanently, depending on the composition of a dye (oxidative or nonoxidative) and its degree of penetration of the hair shaft. The dermatologist's knowledge of dyes, their use, and their possible side effects (contact eczema, cancer, increased porosity, brittleness) can extend to an understanding of cosmetic resources that also treat hair and scalp conditions.

    To describe clinical outcome of dogs with mast cell tumors (MCTs) arising from the oral mucosa, oral mucocutaneous junction, or perioral region of the muzzle and evaluate the potential role of the chemokine receptor type 7 (CCR7) in the biological behavior of these tumors. Retrospective case series. 44 dogs with MCTs of the oral mucosa (n=14), oral mucocutaneous junction (19), or perioral region of the muzzle (11). Medical records were reviewed for information on signalment, regional metastasis, treatments, cause of death, and survival time. Twenty of the 44 cases had stored histologic samples available for immunohistochemical staining for CCR7 For all dogs, median survival time was 52 months. Twenty-six (59%) dogs had regional lymph node metastasis on admission. Median survival time for dogs with lymph node metastasis was 14 months, whereas median survival time was not reached for dogs without lymph node metastasis. Intensity of staining for CCR7 was not significantly associated with the presence of regional lymph node metastasis or survival time. Results suggested that in dogs with MCTs arising from the oral mucosa, oral mucocutaneous junction, or perioral region of the muzzle, the presence of regional lymph node metastasis at the time of diagnosis was a negative prognostic factor. However, prolonged survival times could be achieved with treatment. In addition, CCR7 expression in the primary tumor was not significantly associated with the presence of regional lymph node metastasis or survival time.

    Bezoars are concretions of foreign bodies found in the gastrointestinal tract. In the past, most common method for the treatment of bezoar was surgical management. However, the current treatment methods include chemical dissolution and endoscopic mechanical lithotripsy. There were few reports on the treatment of phytobezoars by nasogastric Cola lavage. However, there was no report succeeded by oral route alone. In our two cases, phytobezoars were treated by oral administration of Coca-Cola. Our patients drank 700-800 mL of Coca-Cola daily, and after two months, complete dissolutions of bezoars were achieved. We report two cases of phytobezoars completely treated by drinking Coca-Cola.

    Full Text Available Extracutaneous involvement in mycosis fungoides (MF carries a poor prognosis. Oral and gastrointestinal (GI tract lesions are both rare locations of disease. We describe the clinical findings of one case with oral and GI MF complicated by perforation after systemic antineoplastic treatment, and review the relevant literature. The patient had a 1-year history of MF before development of tongue and palate tumors. He was treated with local electron beam radiation, but re-presented to the hospital after what was found to be small intestine perforation following systemic antineoplastic therapy. The case reveals key insights into the progression and complications of lymphomas with GI tract involvement.

    The root displacement into the maxillary sinus could be a complication of oral surgery in the upper jaw. In these cases, the root removal is needed in order to avoid the occurrence of sinus pathologies. Piezosurgery techniques could assure a safer management of such complications, because of the clear surgical visibility and the selective ability of cut. The aim of this article is to present a case of oral surgery complication (root displacement in the right maxillary sinus), in which piezosurgery technique helped for a correct and safe clinical management, allowing to reduce the soft tissue damage.

    The oral presentation of the clinical long case is commonly an implied knowledge. The challenge of the presentation is compounded by the examiners' preferences and sometimes inadequate understanding of what should be assessed. To highlight the different opinions and misconceptions of trainers as the basis for improving our understanding and assessment of oral presentation of the clinical long case. Questionnaire was administered during the West African College of Surgeons fellowship clinical examinations and at their workplaces. Eligibility criteria included being a surgeon, a trainer and responding to all questions. Of the 72 questionnaires that were returned, 36(50%) were eligible for the analysis. The 36 respondents were from 14 centers in Nigeria and Ghana. Fifty-two percent were examiners at the postgraduate medical colleges and 9(25%) were professors. Eight(22.2%) indicated they were unaware of the separate methods of oral presentation for different occasions while 21( 58.3%) respondents were aware that candidate used the "5Cs" method and the traditional compartmentalized method in long case oral presentation. Eleven(30.6%) wanted postgraduates to present differently on a much higher level than undergraduate despite not encountering same in literature and 21(58.3%) indicated it was an unwritten rule. Seventeen (47.2%) had not previously encountered the "5Cs" of history of presenting complaint in literature also 17(47.2%) teach it to medical students and their junior residents. This study has shown that examiners definitely have varying opinions on what form the oral presentation of the clinical long case at surgery fellowship/professional examination should be and it translates to their expectations of the residents or clinical students. This highlights the need for standardization and consensus of what is expected at a formal oral presentation during the clinical long case examination in order to avoid subjectivity and bias.

    The presentation herewith as scripted is to describe a case with Nevus sebaceous with oral manifestations. Nevus Sebaceous or Jadassohn's nevus is an epidermal nevus with predominant sebaceous glands seen histologically. Reports of oral involvement have been few ranging from papillomatous growths of the tongue, gingiva, palate to dental abnormalities such as anodontia and dysodontia. The present case describes a nevus sebaceous present on the right half of the face and neck, showing intraoral papillomatous growth on the lateral part of the tongue on the right side. The patient was healthy and did not report involvement of any other organ systems. Intraoral involvement may be seen in patients with Nevus Sebaceous, hence proper screening is important. In patients presenting with large nevi on the head and neck such as ours, involvement of other systems such as ocular, neurologic and oral lesions may be seen, therefore screening of such patients is of importance. Patients with nevus sebaceous may be predisposed to the occurrence of tumours. Therefore, careful screening of such patients is necessary.

    Full Text Available Penile hair tourniquet (PHT is a painless form of penile ischemia, typically seen in toddlers with long-haired mothers, caused by entanglement of hair on the balano-prepucial sulcus, normally associated with circumcision. Its association with hypospadias has been reported only once. A school-aged boy admitted for surgery to treat hypospadias failure was incidentally detected to have PHT and severe hourglass deformity of the penis. Urethral anastomosis and glanuloplasty were done after removal of the constricting ring, without complications. Normal erections were reported during follow up. Treatment may involve urethral reconstruction and penile reimplantation in extreme cases.

    2017-07-12

    Hydroxychloroquine (HCQ) retinopathy can accompany other retinal complications such as cystoid macular edema (CME), which leads to central visual loss. We report a case of CME with HCQ retinopathy that improved with the use of oral acetazolamide, and discussed the possible mechanisms of CME in HCQ retinopathy using multimodal imaging modalities. A 62-year-old patient with systemic lupus erythematosus (SLE) and HCQ retinopathy developed bilateral CME with visual decline. Fluorescein angiography (FA) showed fluorescein leakage in the macular and midperipheral area. After treatment with oral acetazolamide (250 mg/day) for one month, CME was completely resolved, best corrected visual acuity (BCVA) improved from 20/50 to 20/25, and FA examination showed decreased dye leakage in the macular and midperipheral areas. In cases of vision loss in HCQ retinopathy, it is important to consider not only progression of maculopathy, but also development of CME, which can be effectively treated with oral acetazolamide.

    The aim of this case report is to describe the treatment planning of a young child with severe early childhood caries (S-ECC) as well as the prosthetic rehabilitation technique. A 3-year-old female child was referred to the pediatric dentistry clinic with the chief complaint of tooth pain, difficulty in eating and recurrent hospitalizations caused by dental infections. The mother reported intermittent episodes of fever and recurrent swelling of child's face. The girl presented angular cheilitis and was referred to a dietitian. The treatment plain consisted on a behavior changes in oral hygiene habits, exodontias of all primary teeth and oral rehabilitation with a prosthesis. The extracted teeth with periapical lesions were submitted to histopathologic analysis (hematoxilin and eosin staining) and revealed an inflammatory infiltrate. The aesthetic requirement of children with S-ECC has been a challenge to pediatric dentists. In the present case, the oral rehabilitation provided for the children better aesthetic, nutrition, phonation, and functional conditions.

    Periodontal infection is a possible risk factor for respiratory disorders; however, no studies have assessed the colonization of periodontal pathogens in endotracheal tubes (ET). This case-control study analyzed whether periodontal pathogens are able to colonize ET of dentate and edentulous patients in intensive care units (ICU) and whether oral and ET periodontal pathogen profiles have any correlation between these patients. We selected 18 dentate and 18 edentulous patients from 78 eligible ICU patients. Oral clinical examination including probing depth, clinical attachment level, gingival index , and plaque index was performed by a single examiner, followed by oral and ET sampling and processing by quantitative polymerase chain reaction (total bacterial load, Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, and Tannerella forsythia). Data were statistically analyzed by Mann-Whitney U, two-way analysis of variance (p Periodontal pathogens can colonize ET and the oral cavity of ICU patients. Periodontal pathogen profiles tend to be similar between dentate and edentulous ICU patients. In ICU patients, oral cavity represents a source of ET contamination. Although accompanied by higher oral bacterial levels, teeth do not seem to influence ET bacterial profiles.

    Full Text Available Purpose: To report a case of tarantula hairs found in the cornea and discuss treatment. Case Report: A 16-year-old male presented with a 6-week history of right ocular irritation that began after letting his pet tarantula crawl on his face. Slit-lamp examination of the right eye revealed the presence of approximately 16 dark foreign bodies that had the appearance of small hairs. The foreign bodies were removed from the nasal region of the right cornea using Jewelers forceps, and the patient was prescribed a combination neomycin, polymyxin B, and dexamethasone ointment (Maxitrol®, given 4 times per day. Results: The patient presented for follow-up 2 weeks later, with resolution of symptoms. Conclusion: Effective treatment of keratitis caused by tarantula hairs includes taking a detailed history, conducting a careful slit-lamp examination, removal of any accessible hairs, and initiation of treatment with a topical steroid as determined by the clinical picture.

    Full Text Available Henna (Lawsonia inermis L. tattooing has been used in Egypt and India since ancient times. Today this temporary body art is becoming increasingly popular among young people. Various chemicals are added to henna to darken and enhance the definition of tattoos, especially para-phenylenediamine (PPD, which is a strong sensitizer known to cause cross sensitive reactions to azoic dyes and other para-amino compounds. We present the case of an 18-year-old girl who became clinically sensitive to textile dyes after having showed a serious reaction both to her first hair dying when she was 16 years old and following the application of a temporary henna tattoo when she was a kid. The evidence from our literature review showed 33 cases of manifest sensitization to hair dye and only one of observable contact allergy to both hair and textile dyes from henna tattoos. The sensitization of children may have long-life lasting consequences, because of cross-reaction to dyes and other chemicals contained in hair colourants, clothes and drugs. Since tattoos are very popular and globalization has increased the circulation of unauthorized products we point out the need for informative campaigns about the risk of sensitization caused by temporary tattoos.

    Hair loss is a common complaint, both in men and women, and use of prescription medications is widespread. When there is a temporal association between the onset of hair loss and commencement of a medication, the medication is commonly thought to have caused the hair loss. However, hair loss and in particular telogen effluvium may occur in response to a number of triggers including fever, hemorrhage, severe illness, stress, and childbirth, and a thorough exclusion of these potential confounders is necessary before the hair loss can be blamed on the medication. Certain medications are known to cause hair loss by a variety of mechanisms including anagen arrest, telogen effluvium, or accentuation of androgenetic alopecia by androgens. Crown Copyright © 2013.

    Viral oral ulcers are common presentations in pediatric clinics. Although self-limiting, painful ulcerative lesions and inflamed mucosa can decrease oral intake and lead to dehydration. Despite the widespread use of Chinese herbal medicine (CHM) for pediatric upper respiratory disease in Taiwan, there is little evidence for its effectiveness as an antipyretic or in aiding ulcer healing for children with viral oral ulcers. We report two cases of children who presented with viral oral ulcers to illustrate the potential efficacy of CHM treatment in recovery from herpangina (HA) and herpetic gingivostomatitis (HGS). A 10-year-old girl with HA presented with an acute febrile illness associated with small vesicular or ulcerative lesions on the posterior oropharyngeal structures. The family refused western medicine due to a prior anaphylactic skin rash when she had taken sulfa drugs. The other patient was a 4-year-old boy with complaints of painful ulcers and hemorrhagic crusts on the lips. He was diagnosed with HGS and had received ibuprofen and supportive treatments such as hydration and local anesthesia spray for days, characterized by fever, anorexia, and nausea to no effect. Because the patients were suffering from the damp-heat syndrome according to Traditional Chinese Medicine (TCM) differentiation, both were treated using the same herbal formulas powder prescription, named Liang Ge San (LGS) and Gan Lu Xiao Du Dan (GLXDD). After several days of CHM treatment, the oral ulcers were in regression. Follow-up of the frontal view in both patients showed satisfactory disappearance of the sick furred tongue. The results of these case reports show that the early prescription of CHM is an effective modality of alternative treatment for viral oral ulcers. To our knowledge, this is the first report of CHM treatment hastening the recovery from febrile disease with viral oral ulcers in Taiwan. Future experimental studies to determine the definitive mechanism and clinical trials

    2012-08-01

    There is evidence that most South African oral hygiene lecturers lack appropriate qualifications in the field of education. Their teaching skills are based mainly on clinical and practical experience, and this may impact on their understanding of the educational foundations of teaching, learning and assessment. To explore oral hygiene lecturers' knowledge and use of pedagogy and assessment and its alignment. A qualitative descriptive study design was used and case studies of two oral hygiene lecturers, each with qualifications in Education, were analyzed according to three themes: curriculum, pedagogy and assessment. The results showed that both participants had a good understanding of formative assessment (FA) and summative assessment (SA). They made use of FA but in neither case was the application ideal. Both used a range of teaching and assessment strategies but felt accountable to external demands of meeting outcomes. They linked their understanding of pedagogy and assessment to assist in the development of their courses and reported that this alignment had improved the quality of their programmes. This alignment by oral hygiene lecturers can influence curricular and pedagogic strategies. The professional educational development of lecturers in oral hygiene could be influential in improving the profession within the country.

    The development of squamous cell carcinoma from oral lichen planus is controversial. We report a case of intraoral squamous cell carcinoma, which presents together with lesions of oral lichen planus. The aim of this report was to analyze the problem to distinguish between the incipient changes of squamous cell carcinoma from the features described in oral lichen planus, in order to establish an accurate diagnosis of both entities. A 57-year old man with a history of smoking and chronic alcohol intake, who had an ulcerated tumor mass located in the tongue, and bilateral white reticular patches on buccal mucosa and borders of the tongue. The histopathological report was moderately differentiated invasive squamous cell carcinoma and lichen planus respectively. The premalignant nature of OLP is still indeterminate and controversial, this is primarily due to inconsistency in the clinical and histological diagnostic criteria used to differentiate cases of oral lichen planus from lichenoid reactions or other lesions causing intraepithelial dysplasia with high potentially malignant transformation. Oral lichenoid reactions are possibly most likely to develop malignant transformation as compared to the classic OLP lesions.

    Focal epithelial hyperplasia (FEH), or Heck's disease, is a benign proliferative viral infection of the oral mucosa that is related to Human Papil-lomavirus (HPV), mainly subtypes 13 and 32. Although this condition is known to exist in numerous populations and ethnic groups, the reported cases among Caucasians are relatively rare. It presents as asymptomatic papules or nodules on the oral mucosa, gingiva, tongue, and lips. Histopathologically, it is characterized by parakeratosis, epithelial hyperplasia, focal acanthosis, fusion, and horizontal outgrowth of epithelial ridges and the cells named mitozoids. The purpose of this case report was to present 3 cases of focal epithelial hyperplasia in a pediatric age group. Histopathological and clinical features of cases are discussed and DNA sequencing analysis is reported in which HPV 13, HPV 32, and HPV 11 genomes are detected.

    2005-01-01

    Oral Campylobacter species are rarely reported to cause extraoral infections. Here we present three cases of extraoral abscess caused by an oral Campylobacter sp. and a Streptococcus sp. The Campylobacter species were all isolated anaerobically and identified by sequencing analysis of the 16S rRNA gene. The cases included a breast abscess caused by Campylobacter rectus and a non-group A beta-hemolytic streptococcus in a patient with lymphoma, a liver abscess caused by Campylobacter curvus and an alpha-hemolytic streptococcus in a patient with complicated ovarian cancer, and a postobstructive bronchial abscess caused by C. curvus and group C beta-hemolytic Streptococcus constellatus in a patient with lung cancer. The abscesses were drained or resected, and the patients were treated with antibiotics with full resolution of the lesions. The C. curvus cases are likely the first reported infections by this organism, and the C. rectus case represents the second such reported extraoral infection. PMID:15872299

    Dermoscopy, a non-invasive technique for cutaneous diagnosis is being increasingly studied in various disorders of the skin, nails and scalp. However, it has been under-utilized for the diagnosis and characterization of mucosal disorders. The dermoscopic characterization of cutaneous lichen planus and its variants has been well documented with Wickham's striae constituting the hallmark of the condition. However, the dermoscopic features of oral lichen planus with hand-held or videodermoscopy remain to be elucidated. We present the case of a young adult man who presented with asymptomatic white lacy lesions over a bluish-black background over the tongue, patchy hyperpigmentation of the buccal mucosae and gingivae, and longitudinal melanonychia involving some nails. History of intake of any drugs preceding the lesions, smoking, chewing of betel nut and dental implants was negative. Family history was non-contributory. There were no cutaneous lesions suggestive of lichen planus. Mucoscopy (dermoscopy of the mucosa, oral in this case) and onychoscopy were done followed by biopsy from the tongue that confirmed the diagnosis of lichen planus. Oral mucoscopy of the tongue revealed a tri-colored pattern with structureless veil-like grey-white areas (modified Wickham's striae), well-demarcated red glossy erosions, and violaceous-to-brown clods. Additionally, vascular pattern of dotted and linear to curved vessels along the borders of leukoplakia-like areas and erosions were observed. Onychoscopy confirmed lichen planus-associated melanonychia. Dermoscopy also proved useful in conveniently ruling out other disorders typified by mucosal and nail pigmentation such as Laugier Hunziker syndrome and drug-induced changes. Although direct oral microscopy has been used in defining features of oral lichen planus, to the best of our knowledge this case is the first report on mucoscopy or dermoscopy of oral lichen planus.

    2017-10-01

    Full Text Available Oral vegetable granuloma represents an inflammatory lesion of foreign body origin resulting from the implantation of vegetable matter. Controversy regarding its pathogenesis is reflected by the various terminologies used to describe the lesion. Its diverse clinical presentations are due to variations in the antigenic potential of the vegetable material and the host response. As the diagnosis is solely histopathological, it is critical to differentiate vegetable granuloma from other oral granulomatous lesions like tuberculosis, sarcoidosis and Wegner’s granulomatosis. Here, we report six cases with the varied clinicopathological presentation of hyaline ring granulomas in association with different pathological lesions.

    2014-01-01

    Full Text Available Odontomas are the commonest odontogenic tumors of the oral cavity and are by nature asymptomatic. They consist mainly of dental tissue that may or may not be arranged in an orderly fashion. Their presence is often detected accidentally or due to the presence of a dental disturbance such as an unerupted tooth. The very rarity of odontomas erupting into the oral cavity validates the need for more current literature on the phenomenon. Our report of two cases aims to present and discuss the rare event of an erupting odontoma with the dental community.

    Directory of Open Access Journals (Sweden)

    Kamala Rawson

    2017-01-01

    Full Text Available Oral submucous fibrosis (OSF is a premalignant condition mainly associated with the practice of chewing betel quid containing areca nut, a habit common among south Asian people. It is characterized by inflammation, increased deposition of submucosal collagen, and formation of fibrotic bands in the oral and paraoral tissues, which increasingly limit mouth opening. In this paper, we review literature on OSF and the different stages of the disease to help dentists make an early diagnosis and reduce the morbidity and mortality associated with this condition. We also present three cases after treatment with biweekly intralesional injections which resulted in improvement of the subjective symptoms.

    Full Text Available Direct oral anticoagulants are becoming more commonplace for the treatment of nonvalvular atrial fibrillation and deep vein thrombosis. Unfortunately, effective reversal agents are not widely available limiting options for neurosurgical intervention during active anticoagulation. We report a case series of 3 patients treated for aneurysmal subarachnoid hemorrhage while taking direct oral anticoagulants. All three underwent open surgical clipping after adequate time was allowed for drug metabolism. Decision-making must take into account timing of intervention, drug half-life, and currently available reversal agents.

    In the described case of the death of a 53-year-old woman, no toxicological examination was performed directly after death (only an anatomopathological autopsy), although symptoms of serious gastrointestinal disturbances had been present (the woman had been hospitalized twice in the course of several months). It was assumed that the cause of death was myocardial infarction. Five years later, some new circumstances came to light which suggested that somebody could have administered some poison (metals, cyanides) to the woman. Toxicological analysis of postmortem samples from the corpse, exhumed 6 years after death by order of the public prosecutor's office, revealed high tissue mercury contents in biological material (cold vapor atomic absorption spectrometry): small intestine, 1516 ng/g; large intestine, 487 ng/g; liver, 1201 ng/g; heart muscle, 1023 ng/g; and scalp hair, 227 ng/g. In samples of soil from places near the coffin, negligible traces of mercury were found (0.5-1.5 ng/g); contamination by mercury from the environment was ruled out. The presented case is a rare example of recognition of mercury poisoning on the basis of the results of analysis of biological material from an exhumed cadaver.

    Full Text Available Abstract: Erythema multiforme (EM is an acute, self-limited, and sometimes recurring skin condition considered to be a hypersensitivity reaction associated with certain infections and medications. A range of medications can trigger the EM. Non-steroidal anti-inflammatory drugs (NSAIDS which are most commonly prescribed for pain relief can also produce rare adverse reactions such as EM. EM is clinically characterized by a and lsquo; and lsquo;minor'' form and a and lsquo; and lsquo;major'' form. Only few reports have stated about oral EM as the third variant of EM. However it is unclear whether EM involving only oral mucosa is a separate entity or is a part of minor form of EM. In this report three cases of EM are discussed , in which two cases involved exclusively oral mucosal lesions and in one case skin manifestations along with oral mucosa was observed. Also the uncommon adverse effects of NSAIDS is highlighted in this report along with its management. [J Contemp Med 2013; 3(3.000: 193-196

    Laser-assisted hair removal devices aim to remove body hair permanently. In most cases, these devices irradiate the whole area of the skin with a homogenous power density. Thus, a significant portion of the skin, where hair is not present, is burnt unnecessarily causing health risks. Therefore, methods that can distinguish hair regions automatically would be very helpful avoiding these unnecessary applications of laser. This study proposes a new system of algorithms to detect hair regions with the help of a digital camera. Unlike previous limited number of studies, our methods are very fast allowing for real-time application. Proposed methods are based on certain features derived from histograms of hair and skin regions. We compare our algorithm with competing methods in terms of localization performance and computation time and show that a much faster real-time accurate localization of hair regions is possible with the proposed method. Our results show that the algorithm we have developed is extremely fast (around 45 milliseconds) allowing for real-time application with high accuracy hair localization ( 96.48 %).

    To assess the association between exposure to the tobacco, heavy metals and phthalate on early pregnancy and missed abortion.42 women with missed abortion and 57 matched controls (women with normal pregnancies) were recruited between March and May 2012, from the Department of Gynecology and Obstetrics, First Affiliated Hospital of Guangxi Medical University and the People Hospital of Guangxi Zhuang Autonomous Region. The questionnaire survey was carried on to learn about the basic conditions, as well as smoking history of all participants. The levels of tobacco, heavy metal, and phthalate exposure were compared between the 2 groups by measuring nicotine, cocaine, cadmium (Cd), manganese (Mn), plumbum (Pb) and dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP), butyl benzyl phthalate (BBP), di-2-ethyl hexyl phthalate (DEHP) in the hair samples.Out results showed that significant differences in age (P = .042), premarital examination (P = .041), passive smoking (P = .021), and heavy metal exposure (P = .022) were found in the case group compared to the control. In addition, the concentration of nicotine (P = .037), cotinine (P = .018), Cd (P = .01), Pb (P = .038) and DEHP (P = .001) in the hair were significantly higher in the case group. Furthermore, logistic analysis revealed that age [Odds Ratio (OR) 1.172, 95% confidence interval (CI) 1.036-1.327], Cd (OR 8.931, 95% CI 2.003-39.811), Cotinine (OR 4.376, 95% CI 1.159-16.531), DEHP (OR 1.863, 95% CI 1.103-3.146) were important factors contributing to the missed abortion (P < .05).It was demonstrated that high gestational age, passive smoking, heavy metals, and the phthalate exposure were the risk factors for missed abortion, while the premarital health examination was a protective factor. Avoiding these harmful substances before getting pregnant and during the early stages of pregnancy, might help prevent missed abortions. Copyright © 2017 The Authors

    Full Text Available Oral submucous fibrosis (OSMF is a chronic, insidious, generalized, and debilitating condition of the oral mucosa predominantly encountered in South-East Asian countries. Oral submucous fibrosis is etiologically linked to the consumption of the areca nut in flavored formulations or as an ingredient in the betel quid chewed by the communities in these countries. The sweet supari, in their multicolored attractive pouches, is the most common chewed product in children. It is considered a harmless mouth freshener and therefore is consumed in larger amount and is kept in the mouth for a longer time and swallowed by the ignorant children. Factors involved in the consumption of sweet supari are levels of awareness, household environment, peer pressure, low cost, easy availability, etc. Here, we report three cases of OSMF in a 9-year-old girl, 13-year-old boy and a 15-year-old girl and literature review.

    Full Text Available Introduction . Psoriasis and lichen planus are common dermatological conditions, whose coexistence is rarely described. Although the exact etiopathogenesis of both diseases is still unknown, autoimmune factors play an important role in their development. A common feature is also the occurrence of the Köbner phenomenon. The principal differences concern the clinical, histological and immunological events. Objective. To present a patient with oral lichen planus, in whom psoriasis developed. Case report. A 75-year-old patient, with a 3-year history of oral lichen planus, presented itchy erythematous skin lesions initially located in the intertriginous area. Outpatient treatment consisting of topical and oral antifungal medications did not bring significant improvement. Skin biopsy confirmed the diagnosis of psoriasis. Treatment with tar ointment and topical tacrolimus was carried out, resulting in gradual improvement. Conclusions . A review of the literature indicates the existence of possible, but still unexplained, linkages between these two diseases.

    The aim of this article is to report weight loss in patients with schizophrenia after switching from olanzapine standard oral tablet (SOT) to olanzapine orally disintegrating tablets (ODT). In the first case report, the patient was switched to olanzapine ODT in daily dosage of 20 mg, while in the second case report, the patient was switched to olanzapine ODT in daily dosage of 15 mg, and weight loss was similar (14 kg vs. 15 kg). Switching patients from olanzapine SOT to olanzapine ODT treatment resulted in significant weight loss that was maintained during 12 months in both case reports. Further controlled clinical investigations are necessary to evaluate change in weight during treatment with olanzapine ODT, and to improve our understanding of this change.

    The concept of pseudomelanocytic nests has been recently described in the dermatology literature. To our knowledge, this entity has yet to be published in the oral pathology literature. We report 2 cases with features of pseudomelanocytic nests. In both instances, nests of cells suspicious for melanocytes were observed. Interpretation of melan-A was negative. Both cases showed strong and diffuse immunoreactivity of the nested cells to CD68. This immunohistochemical staining pattern is most consistent with a melanophage identity. Pseudomelanocytic nests are a recently described entity that represents a potential diagnostic pitfall. Distinguishing pseudomelanocytic nests from an authentic atypical melanocytic proliferation can be challenging and is important for appropriate patient management. Clinicopathologic correlation with cautious interpretation of immunohistochemistry may be necessary to arrive at the correct diagnosis. These cases represent the first reports of pseudomelanocytic nests in the oral pathology literature. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Prosthetic material should induce minimal pathological reaction when in contact with the oral mucosa, especially during oral rehabilitation of patients with tumors of the oral mucosa. The article presents monitoring of a patient after surgery for cancer of the buccal mucosa at the stage of orthopedic rehabilitation. Treatment plan proposed complex oral rehabilitation. A maxillary complete removable denture was manufactured as well as metalloceramic and partial mandibular dentures. Plasma chemical modification of the removable dentures was planned after correction of the prosthetics and primary adaptation. Removable dentures were applied at the maxilla and mandibula. Per our recommendations, the patient was examined weekly for a month and monthly for 6 months. No new tumors or pathological elements were observed.Conclusions. Changes in critical surface tension of the removable dentures made of acrylic plastic improve their biological characteristics as demonstrated by positive clinical dynamics. Prosthetic constructions with hydrophilic surface are recommended in complex clinical cases when patients with tumors of the oral mucosa require dentures.

    Candida, an opportunistic fungal pathogen, has been implicated in oral and oesophageal cancers. This study aimed to examine oral Candida carriage in 52 oral cancer patients and 104 age-, gender- and denture status-matched oral cancer-free subjects. We assessed general health, smoking and alcohol drinking habits, use of alcohol-containing mouthwash and periodontal status (community periodontal index of treatment needs). Yeasts were isolated using oral rinse technique and genetically identified via Real-Time PCR-High resolution melting curve analysis of conserved ribosomal DNA. Conditional and binary logistic regressions were used to identify explanatory variables that are risk factors for oral cancer. The frequencies of oral yeasts' presence and high oral colonization were significantly higher in oral cancer than non-oral cancer patients (p=001; p=0.033, respectively). No significant difference in the isolation profile of Candida species was found between the two groups, except C. parapsilosis was more frequent in non-oral cancer group. Differences were noticed in the incidence of C. albicans strains where significantly more C. albicans genotype-A was isolated from cancer patients and significantly more C. albicans genotype-B isolated from non-cancer patients. Multiple regression analyses showed significant association with cancer observed for alcohol drinking (OR=4.253; 95% CI=1.351, 13.386), Candida presence (OR=3.242; 95% CI=1.505, 6.984) and high oral colonization (OR=3.587; 95% CI=1.153, 11.162). These results indicate that there is a significant association between oral cancer occurrence and Candida oral colonization and that the observed genotypic diversity of C. albicans strains may play a role in oral carcinogenesis.

    In assessing abstinence from drug or alcohol abuse, hair analysis plays an important role. Cosmetic hair treatment influences the content of deposited drugs which is not always detectable during analysis. Since oxidation of melanin leads to an increase in fluorescence, a microscopic method was developed to distinguish natural from cosmetically treated hair. For validation, natural hair samples were treated with different types of cosmetics and inspected by fluorescence microscopy. Hair samples from 20 volunteers with documented cosmetic treatment and as a proof of concept 100 hair samples from forensic cases were analyzed by this method. Apart from autofluorescence with excitation at 365 nm, no obvious fluorescence was observed in untreated hair samples. Tinting and a natural plant product had no influence on fluorescence, but dyeing procedures including oxidation led to a marked increase in fluorescence. Proof of cosmetic treatment was achieved in hair samples from the 20 volunteers. In 100 forensic cases, 13 samples were characterized as oxidatively treated, which was in accordance with the respective disclosure except for one case where treatment was not admitted. This fluorescence microscopic procedure proved to be fast, easy, and reliable to identify oxidatively treated hair samples, which must be considered especially in evaluating cases of negative drug results.

    Cancer is the second cause of death in Portugal right after cardio vascular diseases. In Portugal the incidence of oral and pharynx cancer (OPC) is higher than uterus and larynx cancers, and in US its frequency is higher than melanoma or uterus cancer, diseases that concern more population than oral cancer. The aim of this paper is to identify preferable anatomic location for oral cancer, mean age of patients, the use of tobacco and alcohol, histological characteristics, staging, type of therapeutics, presence of metastases and 1 and 5 year follow up. Data was collected from clinical charts of 365 cases from the Centro de Lisboa do Instituto Portugues de Oncologia with histological confirmation of malign tumor of the mouth. These cases are the total of oral malign tumors in the years of 1997, 1998 and 1999 in that institution. We observe that despite modern diagnostic and treatment techniques 37,9% of all patients died after first year with evidence of tumor. From all patients just 23,7% were free of disease after 5 years of treatment. Tongue was the principal region affected and the average age was 62, 25 years. It was concluded that 57, 8% of patient were smokers and 43,8% were alcohol drinkers. A high number of patients were submitted to radiotherapy either alone or with other treatment options.

    Traditional methods of hair removal have proven unsatisfactory for many individuals with excessive or unwanted hair. In the last few years, several lasers and xenon flashlamps have been developed that promise to fulfill the need for a practical, safe, and long-lasting method of hair removal. Aggressive marketing of these has contributed to their popularity among patients and physicians. However, significant controversy and confusion surrounds this field. This article provides a detailed explanation of the scientific underpinnings for optical hair removal and explores the advantages and disadvantages of the various devices currently available (Nd:YAG, ruby, alexandrite, diode lasers, and xenon flashlamp). Treatment and safety guidelines are provided to assist the practitioner in the use of these devices. Although the field of optical hair removal is still in its infancy, initial reports of long-term efficacy are encouraging.

    Backgrounds: Lichen planus is a chronic systemic disease and oral mucosa is commonly involved. Oral lichen planus (OLP) most commonly affects middle-aged women. The prevalence of the disease ranges between 0.5% and 2.6% in the general population and the range of malignant transformation varies between 0% and 10%. Objectives: To assess the rate of malignant transformation of OLP samples. Materials and Methods: This retrospective study was carried out on 112 medical records of patients with histological diagnosis of OLP who attended the Department of Pathology at the Educational Hospital from 2005 to 2012. H&E-stained slides were reviewed by two pathologists using strict clinical and histopathological diagnostic World Health Organization (WHO) criteria. Dysplastic changes were diagnosed and graded according to the latest WHO classification. Results: Of the 112 cases diagnosed as OLP, there were 39 males and 73 females and the patients’ ages ranged from 15 to 86 years (mean age 44.5 years). The erosive form with fifty cases was the most common clinical type and the papular type with one case was the least common clinical type. Regarding the site, the buccal mucosa was the most common site with 52 cases. Totally, dysplastic changes were found in 12 samples, among them five cases showed mild dysplasia and seven cases showed moderate dysplasia. One case developed oral squamous cell carcinoma after 3 years. Conclusion: OLP is considered as a premalignant condition by the WHO and several authors. Although the malignancy rate is not so high, to reduce morbidity and mortality from cancer arising on OLP lesions, a regular follow-up examination is recommended. PMID:27721603

    A major challenge of non-invasive human biomonitoring using hair is to assess whether it can be used as an indicator of exposure to Flame Retardants, such as Organophosphate Flame Retardants (PFRs), since the contribution of atmospheric deposition (air and/or dust) cannot be neglected. Therefore, the aim of this study was to evaluate the suitability of using human hair more thoroughly by comparison of (i) levels of PFRs in human hair (from 48 mothers and 54 children), with levels measured in dust and air in their respective households; and (ii) levels of selected PFRs in hair with the levels of corresponding PFR metabolites in matching urine samples collected simultaneously. Most PFRs (tri-n-butyl phosphate (TNBP), 2-ethyl-hexyldiphenyl phosphate (EHDPHP), tri-phenyl phosphate (TPHP), tri-iso-butyl phosphate (TIBP), and tris(2-butoxyethyl) phosphate (TBOEP)) were detected in all human hair samples, tris(2-ethylhexyl) phosphate (TEHP) and tris(1,3-dichloro-iso-propyl) phosphate (TDCIPP) in 93%, tri-cresyl-phosphate (TCP) in 69% and tris(2-chloroethyl) phosphate (TCEP) in 21% of the samples. Levels of individual PFRs ranged between human hair and PFR levels in house dust and/or air were found, e.g. Spearman correlation (rS = 0.561, p exposure. To the best of our knowledge, this is the first study with such design and our findings might help to understand human exposure to and body burdens of PFRs. Copyright © 2015 Elsevier Ltd.

    In the recent years, the fields of study of anti-aging, health and beauty, cosmetics, and hair diseases have attracted significant attention. In particular, human hair is considered to be an important aspect with regard to an attractive appearance. To this end, many workers have sought to understand the formation mechanism of the hair root. However, observing growth in the hair root is difficult, and a detailed mechanism of the process has not yet been elucidated. Hair repeats growth, retraction, and pause cycles (hair cycle) in a repetitive process. In the growth phase, hair is formed through processes of cell proliferation and differentiation (keratinization). During the retraction phase, hair growth stops, and during the resting period, hair fall occurs and new hair grows. This hair cycle is believed to affect the elongation rate, thickness, strength, and shape of hair. Therefore, in this study, we introduce a particle model as a new method to elucidate the unknown process of hair formation, and to model the hair formation process accompanying the proliferation and differentiation of the hair root cells in all three dimensions. In addition, to the growth period, the retraction and the resting periods are introduced to realize the hair cycle using this model.

Lichen planopilaris is a cicatricial alopecia that causes permanent destruction of hair follicles. We report two cases of post-transplantation lesions compatible with lichen planopilaris in both recipient and donor areas. The quality of the hair follicles in the donor area was apparently compromised by lichen planopilaris, the probable cause of hair loss. Similar reports are rare. When lichen planopilaris is suspected, a biopsy of the scalp must be performed to avoid transplantation during disease activity.

    Full Text Available Heterotopic gastrointestinal cysts of the oral cavity are benign lesions usually discovered during infancy. Their pathogenesis is not very clear. They are rare congenital anomalies that result from remnants of foregut-derived epithelium in the head, neck, thorax or abdomen during embryonic development. The majority of these lesions occur in the anterior ventral surface of the tongue and extend to the floor of the mouth. They are confused clinically by surgeons in cases of head and neck masses in children as ranulas, dermoid and thyroglossal cysts, and lymphangioma. We report the case of a 28-day newborn with a 3.6 cm oval mass on the floor of the mouth causing difficulty eating and cyanosis during crying. Complete surgical excision was performed by an oral approach under general anesthesia. Microscopic examination revealed gastric epithelium with tall columnar mucous cells on the surface and numerous short closed crypts, resembling fundal glands and mature gastric epithelium.

    Full Text Available Deep vein thrombosis (DVT is caused by obstruction of blood flow of deep veins in upper and lower limb. One of the precipitating factors for DVT is surgery under general anesthesia exceeding 30 min. However, there are very few reports of DVT associated with surgery of oral and maxillofacial region. In this paper we report two cases of DVT involving left ilio-femoropopliteal deep vein in one patient treated for fractured left angle of mandible and left peroneal vein in the other patient treated for oral sub mucous fibrosis. Clinical and color Doppler examination were performed to diagnose the condition and were referred to vascular surgical unit of higher institute for further management. These cases illustrates any surgery of maxillofacial region is not free from risk of DVT, which can cause fatal pulmonary thromboembolism.

    Full Text Available Myiasis is a pathologic condition in humans occurring because of parasitic infestation. Parasites causing myiasis belong to the order Diptera. Oral myiasis is seen secondary to oral wounds, suppurative lesions, and extraction wounds, especially in individuals with neurological deficit. In such cases, neglected oral hygiene and halitosis attracts the flies to lay eggs in oral wounds resulting in oral myiasis. We present a case of oral myiasis in 40-year-old male patient with mental disability and history of epilepsy.

  6. The oral case presentation: toward a performance-based rhetorical model for teaching and learning

    2015-07-01

    Full Text Available The oral case presentation is an important communicative activity in the teaching and assessment of students. Despite its importance, not much attention has been paid to providing support for teachers to teach this difficult task to medical students who are novices to this form of communication. As a formalized piece of talk that takes a regularized form and used for a specific communicative goal, the case presentation is regarded as a rhetorical activity and awareness of its rhetorical and linguistic characteristics should be given due consideration in teaching. This paper reviews practitioners’ and the limited research literature that relates to expectations of medical educators about what makes a good case presentation, and explains the rhetorical aspect of the activity. It is found there is currently a lack of a comprehensive model of the case presentation that projects the rhetorical and linguistic skills needed to produce and deliver a good presentation. Attempts to describe the structure of the case presentation have used predominantly opinion-based methodologies. In this paper, I argue for a performance-based model that would not only allow a description of the rhetorical structure of the oral case presentation, but also enable a systematic examination of the tacit genre knowledge that differentiates the expert from the novice. Such a model will be a useful resource for medical educators to provide more structured feedback and teaching support to medical students in learning this important genre.

    The oral case presentation is an important communicative activity in the teaching and assessment of students. Despite its importance, not much attention has been paid to providing support for teachers to teach this difficult task to medical students who are novices to this form of communication. As a formalized piece of talk that takes a regularized form and used for a specific communicative goal, the case presentation is regarded as a rhetorical activity and awareness of its rhetorical and linguistic characteristics should be given due consideration in teaching. This paper reviews practitioners’ and the limited research literature that relates to expectations of medical educators about what makes a good case presentation, and explains the rhetorical aspect of the activity. It is found there is currently a lack of a comprehensive model of the case presentation that projects the rhetorical and linguistic skills needed to produce and deliver a good presentation. Attempts to describe the structure of the case presentation have used predominantly opinion-based methodologies. In this paper, I argue for a performance-based model that would not only allow a description of the rhetorical structure of the oral case presentation, but also enable a systematic examination of the tacit genre knowledge that differentiates the expert from the novice. Such a model will be a useful resource for medical educators to provide more structured feedback and teaching support to medical students in learning this important genre. PMID:26194482

    Hairdressing-related burns are preventable and therefore each case is one too many. We report a unique case of a 16-yr-old girl who suffered full-thickness chemical and thermal burns to the nape of her neck and superficial burns to the occiput after her hair had been dyed blond and placed under a dryer to accelerate the highlighting procedure. The wound on the nape of the neck required surgical debridement and skin grafting. The grafted area resulted in subsequent scar formation.

    Analysis of drugs in hair differs from their analysis in other tissues due to the extended detection window, as well as the opportunity that segmental hair analysis offers for the detection of changes in drug intake over time. The antipsychotic drug chlorprothixene is widely used, but few reports exist on chlorprothixene concentrations in hair. In this study, we analyzed hair segments from 20 deceased psychiatric patients who had undergone chronic chlorprothixene treatment, and we report hair concentrations of chlorprothixene and its metabolite desmethylchlorprothixene. Three to six 1-cm long segments were analyzed per individual, corresponding to ~3-6 months of hair growth before death, depending on the length of the hair. We used a previously published and fully validated liquid chromatography-tandem mass spectrometry method for the hair analysis. The 10th-90th percentiles of chlorprothixene and desmethylchlorprothixene concentrations in all hair segments were 0.05-0.84 ng/mg and 0.06-0.89 ng/mg, respectively, with medians of 0.21 and 0.24 ng/mg, and means of 0.38 and 0.43 ng/mg. The estimated daily dosages ranged from 28 mg/day to 417 mg/day. We found a significant positive correlation between the concentration in hair and the estimated daily doses for both chlorprothixene (P = 0.0016, slope = 0.0044 [ng/mg hair]/[mg/day]) and the metabolite desmethylchlorprothixene (P = 0.0074). Concentrations generally decreased throughout the hair shaft from proximal to distal segments, with an average reduction in concentration from segment 1 to segment 3 of 24% for all cases, indicating that most of the individuals had been compliant with their treatment. We have provided some guidance regarding reference levels for chlorprothixene and desmethylchlorprothixene concentrations in hair from patients undergoing long-term chlorprothixene treatment.

    Allergic contact dermatitis following the use of hair dyes is well known. Many chemicals are used in hair dyes and it is unlikely that all cases of hair dye allergy can be diagnosed by means of patch testing with p-phenylenediamine (PPD). The objectives of this study are to identify all hair dye...... in order to help select a number of chemically diverse hair dye substances that could be used in subsequent clinical work. Various information sources, including the Inventory of Cosmetics Ingredients, new regulations on cosmetics, data on total use and ChemId (the Chemical Search Input website provided...... by the National Library of Medicine), were used in order to identify the names and structures of the hair dyes. A QSAR model, developed with the help of experimental local lymph node assay data and topological sub-structural molecular descriptors (TOPS-MODE), was used in order to predict the likely sensitization...

    There is a need to carry out controlled investigations regarding risk factors for early childhood caries (ECC). To study the type of parenting style and oral health practices as risk factors among children with ECC in an Indian preschool population. Two hundred and eleven children with ECC and equal number of controls participated in this case-control study. A questionnaire was answered by parents regarding oral health practices such as oral hygiene methods, feeding habits, daily sugar intake, and dental attendance pattern along with socioeconomic and demographic status. The parenting style was determined using Parenting Styles Dimension Questionnaire (PSDQ) index. Data were statistically analyzed using chi-square test and multiple logistic regression analysis. Risk factors associated with ECC were higher birth order, lower socioeconomic status, non-use of fluoridated toothpaste, breast/bottle feeding for more than one year, presence of formula milk or milk with sugar in the feeding bottle while falling asleep, higher sweet scores in the diet chart, and visiting dentist only when a problem was perceived. Majority of parents of children with and without ECC had authoritative parenting style. Improper oral health practices are the risk factors for ECC. The association of parenting style with ECC could not be confirmed. © 2016 BSPD, IAPD and John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Hair is venerated, cherished, and desired in societies throughout the world. Both women and men express their individual identities through their hairstyles. Healthy hair contributes to successful social assimilation, employment, and overall quality of life. Therefore, hair loss can have detrimental effects on almost every aspect of a person's life. In this review, we discuss the myriad of options that aid in concealing and camouflaging hair loss to facilitate a healthier-appearing scalp. Camouflage options for patients who suffer from hair loss include full or partial wigs, hair extensions, concealing powders and sprays, surgical tattoos, and hair transplants. We describe these modalities in detail and discuss their respective advantages and disadvantages.

    Male pattern baldness, or androgenetic alopecia, affects approximately 50% of the adult population and can cause poor self-image, low self-esteem and have a significant negative impact on the quality of life. An oral nutraceutical supplement based on a marine complex formulation has previously been reported to significantly increase the number of terminal hairs in women with thinning hair. The objective of this double-blind, placebo-controlled study was to confirm the beneficial effects of a similar marine complex supplement in adult male subjects with thinning hair (Viviscal ® Man; Lifes2good, Inc., Chicago, IL, USA). Healthy adult male subjects with thinning hair associated with clinically diagnosed male pattern hair loss were enrolled and randomized to receive study drug or placebo twice daily. At Day 90, subjects indicated a significant improvement in three of six quality of life measures as well as a significant overall improvement in quality of life. After 180 days, significant increases were observed for total hair count, total hair density, and terminal hair density (for each, P = 0.001). The investigator assessments revealed significant improvements in terminal and vellus hair count and terminal hair density. Hair pull test results were significantly lower (fewer hairs removed) for study drug vs. placebo at Days 90 (P < 0.05) and 180 (P < 0.01). There were no reports of treatment-emergent adverse events. The results of this study showed for the first time that a dietary supplement containing a marine complex and other ingredients can decrease hair shedding and promote hair growth in men with thinning hair. © 2016 Wiley Periodicals, Inc.

    Postoperative pressure alopecia (PPA), defined as hair loss caused by prolonged pressure on the patient's scalp during surgery, is an uncommon condition after aesthetic surgery. Originally, it was described for patients who underwent lengthy cardiovascular and gynecologic operations. The authors present a rare case, in which hair loss occurred after secondary breast augmentation (replacement of breast implants). The PPA appeared in the occipitoparietal region of the patient's scalp approximately 2 weeks after surgery. The operation was completed in less than 3 hours, without any fluctuations in the patient's blood pressure or any unusual blood loss. There were no other precipitating factors such as anemia or coagulopathies. The probable cause of this unexpected result was the patient's braided hair coil, which had not been noted before the operation. The patient habitually, and on the day of her operation, combed her hair into a braided coil, which placed extra pressure on the occipitoparietal region. The hair loss was temporary, and hair regrowth was complete within 2 months. This incident may have been avoided if the braided hair coil had been noted by nursing or other medical staff preoperatively. Repositioning the head every 30 minutes and providing adequate head padding during surgery are advised to protect the patient and prevent such incidents. 5. © 2014 The American Society for Aesthetic Plastic Surgery, Inc.

    Anaphylaxis after the ingestion of foods contaminated with mites has recently been recognized. Case series and case reports thus far have shown that mite-contaminated wheat flour is the major cause of oral mite anaphylaxis. However, we have found 8 cases of oral mite anaphylaxis which were caused by mite-contaminated okonomiyaki-mix, a savory Japanese style pancake mix, in our hospital. In addition to our 8 cases, the databases of MEDLINE and ICHUSHI were systematically searched for patients with oral mite anaphylaxis in Japan. Thirty-six patients including our 8 cases with oral mite anaphylaxis were identified. Thirty-four out of 36 cases (94%) ingested okonomiyaki or takoyaki, prepared at home using okonomiyaki-mix or takoyaki-mix which was previously opened and stored for months at ambient temperature. Microscopic examination of culprit mixes of 16 cases including our 1 case revealed contamination of mites such as Dermatophagoides farina (Der f) (5 cases), Tyrophagus putrescentiae (Tyr p) (4 cases), and Dermatophagoides pteronyssinus (Der p) (3 cases). The specific IgE to each mite is generally upregulated in these patients. Especially, the titers of specific IgE to Der p and Der f were more than class 2 in all cases. Mite-contaminated flavored flour is the major cause of oral mite anaphylaxis in Japan.

    Toxic levels of heavy metals and low levels of essential minerals have been suggested to play a critical role in the pathogenesis of autism spectrum disorders (ASD). This study documents the levels of heavy metals and essential minerals in hair samples of children with ASD in Muscat, the urbanized capital of Oman, Muscat. The study included 27 children with ASD and 27 matched non-ASD controls. Parental interviews were held and dietary intake questionnaires completed in conjunction with the collection of hair samples. Analysis of heavy metals and essential minerals was carried out by inductively coupled plasma mass spectrometry. Chi-square analysis and non-parametric Fisher's exact tests were used to assess statistical significance. Children with ASD had significantly higher levels of all 11 analyzed heavy metals in their hair samples (P minerals sulfur, sodium, magnesium, potassium, zinc, and iron, but lower levels of calcium and copper in their hair samples. This study corroborates data from previous studies in different parts of the world indicating the presence of elevated levels of heavy metals and selective depletion of essential minerals in the hair of children with ASD.

    Diagnostic records from 338 canine oral melanomas in 338 dogs received at the Veterinary Medical Diagnostic Laboratory (1992-1999) were reviewed. Of these tumors, 122 plus an additional 7 metastatic melanomas of unknown origin were selected for clinical follow-up, histologic review, and immunohistochemistry. Chow Chow, Golden Retriever, and Pekingese/Poodle mix breeds were overrepresented, whereas Boxer and German Shepherd breeds were underrepresented. There was no gender predisposition and the average age at presentation was 11.4 years. Forty-nine dogs were euthanized due to recurrence or metastasis. The average postsurgical survival time was 173 days. The gingiva and the labial mucosa were the most common sites. Most tumors were composed of either polygonal cells (27 cases, 20.9%), spindle cells (44 cases, 34.1%), or a mixture of the two (polygonal and spindle) (54 cases, 41.9%). Clear cell (3 cases, 2.3%) and adenoid/papillary (1 case, 0.8%) patterns were uncommon. The metastases of 6/6 oral melanomas had morphologic and immunohistochemical features similar to those of the primary tumors. Immunohistochemically, Melan A was detected in 113/122 oral (92.6%) and 5/7 (71.9%) metastatic melanomas. Only 4/163 nonmelanocytic tumors were focally and weakly positive for Melan A. Antibodies against vimentin, S100 protein, and neuron-specific enolase stained 129 (100%), 98 (76%), and 115 (89.1%) of 129 melanomas, respectively. Antibodies against other melanocytic-associated antigens (tyrosinase, glycoprotein 100) did not yield adequate staining. We conclude that Melan A is a specific and sensitive marker for canine melanomas.

    To demonstrate the role of oral acyclovir in monthly regimes after microdebrider assisted excision in 3 patients with adult recurrent respiratory papillomatosis (ARRP). Three patients with ARRP who presented to a tertiary referral hospital in stridor were initially treated with a tracheostomy in order to secure airway. On further evaluation by videolaryngoscopy extensive bilateral laryngeal papillomatosis was noted with history of similar conditions in the past for which they were repeatedly operated. They were admitted and underwent Microlaryngeal surgery and laryngeal microdebrider assisted surgery under general anesthesia. Post operatively a course of oral acyclovir at 800 mg/5 times/day for 5 days was administered. On repeat assessment with videolaryngoscopy at monthly intervals a complete remission of the disease was noted with no residual disease at the end of 1 year in 2 cases. One case had a recurrence. Renal parameters were monitored periodically. It may be concluded that the action of anti viral drugs at regular intervals in addition to a short course of oral steroids lead to rapid recovery and prevented latent virus activation within the laryngo tracheal system hence maintaining long term improvement. This can avoid multiple laryngeal surgeries, repeated respiratory emergencies and risk for malignant transformation in the future thereby reducing morbidity and effect on quality of life.

    Full Text Available Abstract Background The oral cavity is a rare but occasional target for metastases, which may masquerade as various benign and inflammatory lesions, and sometimes also be asymptomatic. Oral metastatic lesions have been described in various cancers, particularly lung, breast and kidney carcinoma. Case presentation We here describe an uncommon case of a hard palate mucosa and gingival metastasis from gastric carcinoma that was originally diagnosed as a periodontal disease. Histopathological examination of a biopsy of the lesion revealed a signet-ring cell carcinoma, and a subsequent biopsy of an ulcerated stomach lesion showed a poorly differentiated gastric carcinoma. The patient underwent gastric resection but died of heart failure on the tenth postoperative day; a post-mortem examination revealed a residual bilateral ovarian infiltration by gastric carcinoma (Krukenberg's tumor. Conclusion An occult carcinoma of the stomach may rarely metastasise to the oral cavity even as a first and exclusive manifestation; it is important to bear this possibility in mind because such conditions may mimic a benign disease.

    Vascular Ehlers-Danlos syndrome (vEDS) is a rare genetic condition related to mutations in the COL3A1 gene, responsible of vascular, digestive and uterine accidents. Difficulty of clinical diagnosis has led to the design of diagnostic criteria, summarised in the Villefranche classification. The goal was to assess oral features of vEDS. Gingival recession is the only oral sign recognised as a minor diagnostic criterion. The authors aimed to check this assumption since bibliographical search related to gingival recession in vEDS proved scarce. Prospective case-control study. Dental surgery department in a French tertiary hospital. 17 consecutive patients with genetically proven vEDS, aged 19-55 years, were compared with 46 age- and sex-matched controls. Complete oral examination (clinical and radiological) with standardised assessment of periodontal structure, temporomandibular joint function and dental characteristics were performed. COL3A1 mutations were identified by direct sequencing of genomic or complementary DNA. Prevalence of gingival recession was low among patients with vEDS, as for periodontitis. Conversely, patients showed marked gingival fragility, temporomandibular disorders, dentin formation defects, molar root fusion and increased root length. After logistic regression, three variables remained significantly associated to vEDS. These variables were integrated in a diagnostic oral score with 87.5% and 97% sensitivity and specificity, respectively. Gingival recession is an inappropriate diagnostic criterion for vEDS. Several new specific oral signs of the disease were identified, whose combination may be of greater value in diagnosing vEDS.

    Full Text Available Extramedullary plasmacytoma (EMP and solitary bone plasmacytoma (SBP represent a disease continuum through a multistage process of cell differentiation, survival, proliferation, and dissemination, strictly related to multiple myeloma (MM, the second most common hematological malignancy. Herein, we report two cases of recurrent oral plasmacytoma progressed to MM, in which the first clinical sign of a more widespread disease was limited to the mouth. Based on our experience, we recommend a strict workup for the differential diagnosis between EMP, SBP, and MM for patients with oral plasmacytoma, including radiological exam of the skeleton, magnetic resonance imaging (MRI of the bone, and positive emission tomography (FDG-PET. MRI and possibly PET can all be used to more sensitively detect EM plasmacytoma sites.

    Terbinafine is a commonly prescribed antifungal agent used in the treatment of trichophytic onychomycosis and chronic cutaneous mycosis that are resistant to other treatments. This case report highlights a rarely documented but important adverse hepatic reaction that was caused by the use of oral terbinafine. A woman in her thirties presented with a 3-week history of jaundice, malaise, itching, nausea, decreased appetite, weight loss, dark orange urine and intermittent non-radiating epigastric pain. She had recently finished a 3-week course of oral terbinafine for a fungal nail infection. Liver biopsy findings were consistent with chronic active hepatitis secondary to a drug reaction. A few days after initial presentation, the patient developed erythema nodosum. Delayed development of erythema nodosum secondary to terbinafine could not be excluded. 2014 BMJ Publishing Group Ltd.

    Piercing is popular among young people, who view this practice as a sign of marginality, beauty, or group identity. This study is performed on healthy individuals with oral and facial piercings. Seventy oral and facial piercings were evaluated (17 in the tongue, 13 in the lower lip, 18 in the nostril, 7 in the eyebrow, and 15 in the ear). A specifically designed protocol was used to assess possible complications (inflammatory reactions, pain, dental alterations). Nonparametric tests were used for the statistical analysis of the results. The general complications recorded comprised pain (60% of cases), inflammatory reactions (34.3%), bleeding (24%), dental fractures or fissures (20%), and gingival damage (26.7%). Tongue piercing is associated with pain, inflammatory reactions, and dental problems.

    Gc protein-derived macrophage-activating factor (GcMAF) immunotherapy has been steadily advancing over the last two decades. Oral colostrum macrophage-activating factor (MAF) produced from bovine colostrum has shown high macrophage phagocytic activity. GcMAF-based immunotherapy has a wide application for use in treating many diseases via macrophage activation or for use as supportive therapy. Three case studies demonstrate that oral colostrum MAF can be used for serious infection and chronic fatigue syndrome (CFS) without adverse effects. We demonstrate that colostrum MAF shows promising clinical results in patients with infectious diseases and for symptoms of fatigue, which is common in many chronic diseases.

    2014-03-01

    Full Text Available Introduction Dental and maxillofacial anomalies have multiple and complex causes. Most frequent among these are poor oral habits. A large number of children present with oral malocclusions, most of which are caused by deforming oral habits. It is important to learn about risk factors for this condition in order to institute preventive measures, early detection and treatment, and identification of low- and high-risk groups. Objectives To identify risk factors associated with deforming oral habits, which, if maintained over time, are responsible for occlusion defects, speech disorders, and can affect physical and emotional child development. Methods A case-control study of children presenting with deforming oral habits in the municipality of Manzanillo in Granma province was conducted between January and August 2013. 540 children aged 5 to 11 were included of which 180 had deforming oral habits and were asked to fill out a survey to identify specific type of habits leading to malocclusion. The case group was composed of children with deforming habits, and the remaining 360 children without poor oral habits were the control group. Each case was randomly matched to two control cases. The children’s mothers were also surveyed to gather supplemental information. Results Children with deforming oral habits were mostly female. At age 10, onychophagia was the predominant oral deforming habit. Risk factors detected for these habits were sociobiological maternal and child variables such as low and high birth weight, maternal breastfeeding inexperience, and discord in the family. Conclusions The study identified likely risk factors associated with deforming oral habits. These are discord in the family, birth weight, and lack of breastfeeding experience.

    Full Text Available Anaphylaxis induced by exercise after the intake of certain foods is referred to as food-dependent exercise-induced anaphylaxis (FDEIA. Only the preventive medication such as oral sodium cromoglycate and oral combined cetirizine-montelukast was tried in FDEIA. Specific oral tolerance induction (SOTI using IFN-gamma was tried in 2 cases of FDEIA for wheat. Merely, exercise accompanied every treatment just after the intake of allergenic foods during treatment. Patients acquired tolerance for wheat in both cases successfully. After treatment, two patients take wheat in their food living freely. Conclusively, SOTI using IFN-gamma was effective as the causative treatment for allergenic foods in FDEIA.

    Tooth decay is the most common paediatric disease and there is a serious paediatric tooth decay epidemic in Alaska Native communities. When untreated, tooth decay can lead to pain, infection, systemic health problems, hospitalisations and in rare cases death, as well as school absenteeism, poor grades and low quality-of-life. The extent to which population-based oral health interventions have been conducted in Alaska Native paediatric populations is unknown. To conduct a systematic review of oral health interventions aimed at Alaska Native children below age 18 and to present a case study and conceptual model on multilevel intervention strategies aimed at reducing sugar-sweetened beverage (SSB) intake among Alaska Native children. Based on the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) Statement, the terms "Alaska Native", "children" and "oral health" were used to search Medline, Embase, Web of Science, GoogleScholar and health foundation websites (1970-2012) for relevant clinical trials and evaluation studies. Eighty-five studies were found in Medline, Embase and Web of Science databases and there were 663 hits in GoogleScholar. A total of 9 publications were included in the qualitative review. These publications describe 3 interventions that focused on: reducing paediatric tooth decay by educating families and communities; providing dental chemotherapeutics to pregnant women; and training mid-level dental care providers. While these approaches have the potential to improve the oral health of Alaska Native children, there are unique challenges regarding intervention acceptability, reach and sustainability. A case study and conceptual model are presented on multilevel strategies to reduce SSB intake among Alaska Native children. Few oral health interventions have been tested within Alaska Native communities. Community-centred multilevel interventions are promising approaches to improve the oral and systemic health of Alaska Native

    The presence of hair plays an important role in people's overall physical appearance and self-perception. As a result of increased life expectancy, the desire to look youthful plays a bigger role than ever.The use of medicinal plants is as old as mankind and the market will face many new products containing natural oils and herbs in coming years. In traditional Iranian medicine, many plants and herbal formulations are reported for hair growth as well as the improvement in hair quality. The aim of this article is to introduce effective medicinal plants in traditional Iranian medicine to prevent gray hair and advocate them as the new products. The present investigation is an overview study and has been codified by library search in the main sources of traditional Iranian medicine. In traditional Iranian medicine, three types of formulations are proposed to prevent gray hair, namely (i) treatment compounds, (ii) preventive compounds, and (iii) hair dyes to color gray hairs. Our search showed that the main parts of a plant that is used in the treatment and preventive compounds are seeds and fruits. These are primarily in the form of topical oil or oral compound (electuary). The majority of plant parts used in hair dyes is from the fruit and/or leaves. Natural products are highly popular and the use of plant extracts in formulations is on the rise. This is because synthetic based product may cause health hazards with several side effects. Considering the increased popularity of herbal drugs in hair care, it is worthwhile to conduct systemic investigation on the production and efficacy of these drugs. We trust that our investigation would encourage the use of traditional Iranian medicine in future hair care products.

    Oxidation hair-dyes, which are the principal hair-dyes, sometimes induce painful sensory irritation of the scalp caused by the combination of highly reactive substances, such as hydrogen peroxide and alkali agents. Although many cases of severe facial and scalp dermatitis have been reported following the use of hair-dyes, sensory irritation caused by contact of the hair-dye with the skin has not been reported clearly. In this study, we used a self-assessment questionnaire to measure the sensory irritation in various regions of the body caused by two model hair-dye bases that contained different amounts of alkali agents without dyes. Moreover, the occipital region was found as an alternative region of the scalp to test for sensory irritation of the hair-dye bases. We used this region to evaluate the relationship of sensitivity with skin properties, such as trans-epidermal water loss (TEWL), stratum corneum water content, sebum amount, surface temperature, current perception threshold (CPT), catalase activities in tape-stripped skin and sensory irritation score with the model hair-dye bases. The hair-dye sensitive group showed higher TEWL, a lower sebum amount, a lower surface temperature and higher catalase activity than the insensitive group, and was similar to that of damaged skin. These results suggest that sensory irritation caused by hair-dye could occur easily on the damaged dry scalp, as that caused by skin cosmetics reported previously.

  16. Oral cutaneous sinus tract, vertical root fracture, and bisphosphonate-related osteonecrosis: a case report.

    Oral cutaneous sinus tracts (OCSTs) of dental origin are often initially misdiagnosed and inappropriately treated. Accurate diagnosis is especially important in cases of bisphosphonate (BP) therapy because extraction may lead to a risk of osteonecrosis. A case report of misdiagnosis related to a tooth with a vertical root fracture in an oncologic patient treated with BPs is reported here. In 2011, a 75-year-old woman was examined at the oral medicine clinic because of pain and swelling of the left submandibular area. The patient's medical history included oral and intravenous BP therapy because she was diagnosed with metastatic breast cancer and left maxillary stage 1 antiresorptive agent-induced osteonecrosis of the jaw. The lower left odontogenic region showed no signs or symptoms, and no apical pathosis was observed on imaging. Although antibiotics were applied, clinical symptoms worsened and an OCST appeared. Intravenous antibiotic treatment was pursued. Biopsy and direct smear from fistula were not conclusive. A diagnosis of a nonexposed variant of stage 3 antiresorptive agent-induced osteonecrosis of the jaw was established. Symptoms resolved after 2 weeks of antibiotic treatment and reappeared a month later. Endodontic examination revealed that the origin of the OCST was tooth no. 18 caused by a vertical root fracture, and the tooth was extracted. The patient was scheduled for routine checkups because of the fact that osteonecrosis may occur in intravenous BP-treated patients. Early correct diagnosis can prevent unnecessary and ineffective antibiotic therapy and surgical intervention, which is not recommended in intravenous BP cases.

    Oral lichen planus (OLP) is a chronic inflammatory disorder of the oral mucosa of unknown etiology. Clinically, the erosive type of OLP (erosive OLP) can show features similar to those of pemphigus vulgaris (PV), an autoimmune blistering disorder in which desmoglein (Dsg)3 is targeted. In addition to clinical and histopathological findings, immunological studies, including direct immunofluorescence (IF), indirect IF and enzyme-linked immunosorbent assay (ELISA) that detect autoantibodies to Dsg3, are helpful in differentiating erosive OLP from PV. Here, we show two cases of erosive OLP with autoantibodies to Dsg3. Patient 1 was a 68-year-old woman with chronic erosions of the oral mucosa, in which elevated levels of immunoglobulin (Ig)G autoantibodies to Dsg1 and Dsg3 were detected by ELISA. Patient 2 was an 85-year-old woman with white striae with erosions on the lateral sides of the buccal mucosa with elevated levels of IgG autoantibodies to Dsg3 detected by ELISA. Histopathological findings from both cases showed lichenoid dermatitis, and both direct and indirect IF showed no tissue-bound IgG autoantibodies. From these findings, the diagnosis of erosive OLP was made. Immunological assays revealed both cases to have IgG-directing calcium-independent linear epitopes on Dsg3, which are suggestive of non-pathogenic autoantibodies. In addition, autoantibodies to Dsg3 in patient 2 reacted with a prosequence-possessing precursor form of Dsg3 but not with the mature form of the molecule. The present study suggests that erosive OLP may develop anti-Dsg3 autoantibodies, which should be carefully assessed. © 2016 Japanese Dermatological Association.

    The oral cavity is a rare but occasional target for metastases, which may masquerade as various benign and inflammatory lesions, and sometimes also be asymptomatic. Oral metastatic lesions have been described in various cancers, particularly lung, breast and kidney carcinoma. We here describe an uncommon case of a hard palate mucosa and gingival metastasis from gastric carcinoma that was originally diagnosed as a periodontal disease. Histopathological examination of a biopsy of the lesion revealed a signet-ring cell carcinoma, and a subsequent biopsy of an ulcerated stomach lesion showed a poorly differentiated gastric carcinoma. The patient underwent gastric resection but died of heart failure on the tenth postoperative day; a post-mortem examination revealed a residual bilateral ovarian infiltration by gastric carcinoma (Krukenberg's tumor). An occult carcinoma of the stomach may rarely metastasise to the oral cavity even as a first and exclusive manifestation; it is important to bear this possibility in mind because such conditions may mimic a benign disease

    Full Text Available Nowadays, hair care and style play a very important role in people’s physical aspect and self-perception. Hair cosmetics can be distinguished into two main categories: cosmetics with temporary effect on the hair, for example shampoos, conditioners, sprays, and temporary colors; and cosmetics with permanent effect on the hair, such as permanent waves, relaxers, bleaches and permanent colors. These cosmetic procedures may induce hair abnormalities. We provide an overview on the most important characteristics of these procedures, analyzing components and effects on the hair. Finally, we evaluated new camouflage techniques and tattoo scalp.

    We describe the eleventh major outbreak of foodborne Trypanosoma cruzi transmission in urban Venezuela, including evidence for vertical transmission from the index case to her fetus. After confirming fetal death at 24 weeks of gestation, pregnancy interruption was performed. On direct examination of the amniotic fluid, trypomastigotes were detected. T. cruzi specific-polymerase chain reaction (PCR) also proved positive when examining autopsied fetal organs. Finally, microscopic fetal heart examination revealed amastigote nests. Acute orally transmitted Chagas disease can be life threatening or even fatal for pregnant women and unborn fetuses owing to vertical transmission. There is therefore an urgent need to improve national epidemiologic control measures.

    To evaluate the outcome in terms of progression-free interval (PFI) and overall survival time (ST) after curative-intent resection of oral melanoma in dogs. Retrospective case series. 70 client-owned dogs. An electronic medical record search and review was performed for dogs that underwent curative-intent resection of oral melanoma (May 1, 1998, to December 31, 2011). Information gathered included signalment, oral location of tumor, staging results, type of surgery, type of adjuvant therapy, findings on histologic evaluation, and outcome. 36 (51.4%), 16 (22.9%), 13 (18.6%), and 1 (1.4%) of 70 dogs had tumors classified as stage I, II, III, and IV, respectively; tumor stage could not be determined for 4 (5.7%) dogs because of the lack of tumor size information. Fifty-one (72.9%) dogs had tumors completely excised. Twenty-nine (41.4%) dogs received adjuvant therapy. Median PFI and ST were 508 and 723 days, respectively. Thirty-two (45.7%) dogs had disease progression. Significant associations with PFI or ST were found for administration of adjuvant therapy, presence of metastatic disease at the time of diagnosis, higher tumor stage (III or IV), increased tumor size (> 3 cm), and sexually intact female dogs. Administration of adjuvant treatment was associated with a 130% increased hazard (hazard ratio, 2.3; 95% confidence interval [CI], 1.0 to 5.0) of disease progression; the presence of metastases at the time of diagnosis was associated with a 281% increased hazard (hazard ratio, 3.8; 95% CI, 1.5 to 9.6) of death. Results indicated that dogs with oral melanoma can have a long PFI and ST after resection with wide margins.

    To evaluate the characteristics and outcomes of dogs with stage I, II, III, or IV oral malignant melanoma treated by various types of radiotherapy. Retrospective case series. 111 dogs. Medical records of dogs with oral malignant melanoma treated by radiotherapy (with or without adjunctive treatments) at a veterinary medical center between July 2006 and December 2012 were reviewed. Information regarding signalment, tumor location, disease stage, treatment protocols, adverse effects, and survival time were obtained from medical records and by telephone follow-up. Associations between variables of interest and outcome were analyzed. Dogs received orthovoltage x-ray (n = 68), megavoltage x-ray (39), or electron beam (4) radiotherapy. Adjunctive treatments included debulking surgery (n = 18), chemotherapy (39), or both (27). Median survival times for dogs with stage I, II, III, and IV melanoma were 758 days (n = 19), 278 days (24), 163 days (37), and 80 days (31), respectively, and differed significantly between dogs with stage I disease and those with all other disease stages. Among dogs with stage III melanoma, risk of death was significantly higher in those that received orthovoltage x-ray treatment than in those that received megavoltage x-ray treatment. Severe (primary or secondary) adverse effects were identified in 9 dogs. Median survival time was significantly longer for dogs with stage I oral malignant melanoma than for dogs with more advanced disease at the time of staging. The staging system used may be a useful tool for prognosis prediction in dogs undergoing similar treatment protocols for oral malignant melanomas.

    Head hair analysis for drugs and drug metabolites has been used widely with the aim of detecting exposure in the weeks or months prior to sample collection. However, inappropriate interpretation of results has likely led to serious miscarriages of justice, especially in child custody cases. The aim of this review is to assess critically what can, and perhaps more importantly, what cannot be claimed as regards the interpretation of hair test results in a given set of circumstances in order to inform future testing. We searched the PubMed database for papers published 2010-2016 using the terms "hair" and "drug" and "decontamination", the terms "hair" and "drug" and "contamination", the terms "hair" and "drug-facilitated crime", the terms "hair" and "ethyl glucuronide", and the terms "hair", "drug testing" and "analysis". Study of the reference lists of the 46 relevant papers identified 25 further relevant citations, giving a total of 71 citations. Hair samples: Drugs, drug metabolites and/or decomposition products may arise not only from deliberate drug administration, but also via deposition from a contaminated atmosphere if drug(s) have been smoked or otherwise vaporized in a confined area, transfer from contaminated surfaces via food/fingers, etc., and transfer from sweat and other secretions after a single large exposure, which could include anesthesia. Excretion in sweat of endogenous analytes such as γ-hydroxybutyric acid is a potential confounder if its use is to be investigated. Cosmetic procedures such as bleaching or heat treatment of hair may remove analytes prior to sample collection. Hair color and texture, the area of the head the sample is taken from, the growth rate of individual hairs, and how the sample has been stored, may also affect the interpretation of results. Toxicological analysis: Immunoassay results alone do not provide reliable evidence on which to base judicial decisions. Gas or liquid chromatography with mass spectrometric detection

    After the last case of type 1 wild poliovirus (WPV1) was reported in 2007, Somalia experienced another outbreak of WPV1 (189 cases) in 2013. We conducted a retrospective, matched case-control study to evaluate the vaccine effectiveness (VE) of oral polio vaccine (OPV). We retrieved information from the Somalia Surveillance Database. A case was defined as any case of acute flaccid paralysis (AFP) with virological confirmation of WPV1. We selected two groups of controls for each case: non-polio AFP cases ("NPAFP controls") matched to WPV1 cases by age, date of onset of paralysis and region; and asymptomatic "neighborhood controls," matched by age. Using conditional logistic regression, we estimated the VE of OPV as (1-odds ratio)×100. We matched 99 WPV cases with 99 NPAFP controls and 134 WPV1 cases with 268 neighborhood controls. Using NPAFP controls, the overall VE was 70% (95% confidence interval [CI], 37-86), 59% (2-83) among 1-3 dose recipients, 77% (95% CI, 46-91) among ≥4 dose recipients. In neighborhood controls, the overall VE was 95% (95% CI, 84-98), 92% (72-98) among 1-3 dose recipients, and 97% (89-99) among ≥4 dose recipients. When the analysis was limited to cases and controls ≤24 months old, the overall VE in NPAFP and neighborhood controls was 95% (95% CI, 65-99) and 97% (95% CI, 76-100), respectively. Among individuals who were fully vaccinated with OPV, vaccination was effective at preventing WPV1 in Somalia.

    A simple new technique for examining single hair strands to obtain linear mass densities, longitudinal profiles and transverse distribution of each trace element is described. It is primarily based upon the PIXE technique, in combination with proton back- scattering. The three main components of this technique are: 1) An accurate way of using an interpolation method to evaluate the magnitude of the correction factor accounting for the proton energy loss and X-ray absorption in the bulk of the hair is formulated; 2) A simple method to qualitatively determine the transverse distribution of each trace element in a hair is in- troduced and proved to be effective; 3) Proton back-scattering is proved to be capable of providing an ideal linear measure of the geometric hair diameter, one of the most important parameters in quantifying the results of PIXE measurements in mass concentrations. Using the technique, a PIXE system designed and constructed for routine longitudinal scanning of single hair strands is also described. (Author)

    2012-02-01

    Full Text Available Lichenoid reactions represent a family of lesions with different etiologic factors and a common clinical and histologic appearance. Lichen planus is included with lichenoid reactions and is a relatively common chronic mucocutaneous disorder. The most important complication of lichenoid reactions is the possibility of malignant transformation. That is why it has been considered a precancerous condition. Although the malignant transformation rate varies widely in the literature, from 0.4 to 6.5 percent, in most studies it does not exceed 1%. The aim of this paper is to report a rare case of squamous cell carcinoma (SCC arising within an oral lichenoid lesion in a 17-year-old woman, where SCC is very uncommon. The patient did not have any risk factors and was healthy. The lesion was located on the border of the tongue. In view of the common occurrence of OLP (oral lichen planus and the unresolved issues regarding its premalignant potential, this case report illustrates the need for histologic confirmation and a close follow-up of clinical lesions with lichenoid features.

  15. Two case reports of oral ulcers with lamotrigine several weeks after oxcarbazepine withdrawal.

    2007-05-01

    To report two cases of mouth ulcers in lamotrigine patients after oxcarbazepine withdrawal. The first patient was a 35-year-old woman with bipolar disorder II (BD II) started on lamotrigine and tapered off oxcarbazepine while an inpatient. The second patient was a 36-year-old man with BD II. He was discharged on lamotrigine and oxcarbazepine with the recommendation of a slow withdrawal of oxcarbazepine. Many weeks after hospital discharge and after a stable lamotrigine dose had been established, both patients developed painful mouth ulcers that were diagnosed during outpatient visits. The first patient developed ulcers 39 days after oxcarbazepine was stopped and the ulcers resolved 4 days after lamotrigine discontinuation. The second patient was taking 1200 mg/day of oxcarbazepine and after leaving hospital decreased this to 600 mg/day. Twenty-two days after the oxcarbazepine decrease, he developed oral ulcers that resolved with oxcarbazepine and lamotrigine discontinuation. Lamotrigine is mainly metabolized by glucuronidation, specifically by the uridine 5'-diphosphate glucuronosyltransferases 1A4 (UGT1A4). Carbamazepine is a UGT1A4 inducer. These two cases suggest that oxcarbazepine may also induce lamotrigine metabolism. The discontinuation or dosage decrease of carbamazepine or oxcarbazepine may be associated with a slow increase of lamotrigine levels over several weeks and thus increase risk of lamotrigine toxicity that may manifest as oral ulcers. Hospital psychiatrists need to be aware that discontinuation of inducers may take several weeks to manifest as side effects.

The temporomandibular joint (TMJ dysfunction is involved in 4–35% of AS cases, and is correlated to the severity and extension of AS. Even though AS-caused TMJ ankylosis is exceptional, one should have high index of suspicion of TMJ ankylosis in AS for an early detection, because it is an extremely serious and disabling condition that causes problems with mastication, swallowing, digestion, speech, appearance and poor oral hygiene with heavy caries.

A 54-year-old male patient sought medical attention at the Department of Periodontology and Oral Medicine, Clinic for Dentistry at the Military Medical Academy, Belgrade, Serbia, with the chief complaint of pain in the area of the upper left canine in the presence of limited mouth opening. The treatment plan consisted of upper left canine management and rehabilitation of the remaining teeth in the frontal and the premolar region in both, the upper and lower jaw. Even though molar region needed to be treated, unfortunately it was not in the treatment plan because ankylosis of TMJ made the treatment impossible. Conclusions. The patients with AS-caused TMJ ankylosis are considered a diagnostic challenge to routine dentistry. Accent should be given to early diagnosis and multidisciplinary approach in the treatment of the AS patients towards the favorable disease course and outcome.

    Full Text Available Background: Human cancers comprise a large group of diseases that despite modern methods of diagnosis and advanced treatment techniques its mortality rate is high. Considering the role of environmental and cultural factors in the prevalence of oral cancer, epidemiological studies have a great importance. Objective: The aim of this research was to determine the prevalence of oral squamous cell carcinoma (OSCC in the province of Qazvin in a period of ten years. Methods: In this descriptive - analytical study, the documents of 88 patients with OSCC that were recorded by the Qazvin Cancer Registry Center during 2003-13, were used. Demographic data including age, sex and location of lesions were extracted from patient records. Data analysis were performed using chi-square, t-test and fisher exact test. Findings: Among the 88 patients, the average age was 64.3±17.7. The male to female ratio was 1 to 1.37 and the most involved area was tongue with 39 cases (63.9%, and the lowest was upper lip with 1 case (1.6%. The most of the patients were in the age between 70-80 years old. Conclusions: Pattern of OSCC in this study was similar to the other studies but the number of females and the mean age of patient had increased. Also, the mean age of patients was increased in eight decades and the most involved area tongue was reported.

    2006-04-01

    Full Text Available A case of chronic bullous type mucocutaneous disease involving oral mucosa was reported from a 56 years old man with never healing oral ulcers and wound on the perianal skin for three years. There were also red and black spots on the limb and back skin and a lesion on nail. Painful oral lesion consisted of mucous erosion, desquamative gingivitis, and sloughing area on palate and tongue. The patient is diabetic. The first perianal skin diagnosis was granulomatous candidasis with differential diagnosis pemphigus vegetates and acuminarum condiloma. However the histopathologic examination did not support these diagnosis. After several histopathologic examinations, the latest perianal skin diagnosis was lichen planus with differential diagnosis granulomatous vasculitis, bowenoid papulosis and pyodema gangrenosum. Other skin diagnosis was erythema multiforme. Oral diagnosis was mucous membrane pemphigoid with differential diagnosis lichen planus, Behçet's syndrome and erythema multiforme. Oral histopathologic examinations showed a sub-epithelial blister, which supported mucous membrane pemphigoid. A lip balm, prednisone 5 mg oral rinse and multivitamins were given but oral improvement started after blood sugar level was controlled. Conclusion: It is not yet known whether skin and oral mucous lesions are from the same disease or not.

    Therapy-related myelodysplastic syndrome (t-MDS) and therapy-related leukemia (TRL) are reported increasingly often, and we report two cases of T-MDS after concurrent chemoradiotherapy (CCRT) with oral cancer. Patients underwent CCRT with cisplatin (CDDP) or carboplatin (CBDCA). The interval between primary CCRT and t-MDS was 11 months in 1 case and 14 years in the other. Chromosomal analysis indicated abnormal karyotypes. Platinum has a relatively lower t-MDS risk than alkylating agents or topoisomerase II inhibitors, but our experience supports concurrent use of radiotherapy with platinum affects the risk of t-MDS. If pancytopenia is detected after CCRT, bone marrow and cytogenetic examinations should be conducted to rule out t-MDS. (author)

    Dental infections, frequent in the general population, are a common cause of inflammation with systemic impact, and are the most common cause of orofacial pain. Temporomandibular disorders are also frequent in the elderly and represent an important cause of secondary headache. Both inflammation and pain can also contribute to cognitive, functional and behavioral impairment of the elderly and aggravate symptoms of patients with Alzheimer’s disease (AD). We report a case of a 74-year-old woman with AD and chronic facial pain who had a significant improvement in functional activities as well as in cognition and depressive symptoms after successful treatment of her facial pain. Patients with AD have higher compromise of oral health with infections and teeth loss. The investigation of orofacial pain should be performed in patients with AD, because of the associations reviewed and given the potential for improvement as highlighted by this case. PMID:29213678

    Full Text Available Phaeochromocytoma is a rare neuroendocrine catecholamine-secreting tumour. This type of tumour poses multidimensional anaesthetic challenges as it has an unpredictable clinical course during surgical resection. The alpha-blocking agent phenoxybenzamine remained the mainstay in preoperative preparation before the introduction of beta-blocking agents. We report four cases operated between 2009–2012 at Sultan Qaboos University Hospital, Muscat, Oman. The cases were prepared with oral labetalol, as the alpha-blocking drug phenoxybenzamine was not immediately available. Responses to simulated stress were tested in the theatre before surgery. Anaesthesia was induced under invasive arterial pressure monitoring and magnesium sulphate infusion. Rare intraoperative surges in blood pressure during tumour manipulation were treated with sodium nitroprusside infusions and phentolamine boluses. All of the patients had an uneventful postoperative recovery. Preoperative treatment with labetalol has rarely been reported and can be considered as a potential therapeutic option with optimal patient monitoring if phenoxybenzamine is unavailable.

    It is evident that social and behavioural factors influence on individuals' general health and quality of life. Nevertheless, information about the influence of dietary habits on oral health-related quality of life is limited; especially among patients with type 2 diabetes (T2D). The aim of this study was to examine the influence of dietary habits and clinical oral health indicators on oral health-related quality of life in individuals with and without T2D. A total of 149 T2D cases and 298 controls were recruited for this age and gender matched case-control study. Questionnaire-guided interviews were conducted to collect data about socio-demographic characteristics, consumption of food items per week (milk, meat, eggs, vegetables, fruits, sweets and bread) and oral impact on daily performance (OIDP). Plaque index, bleeding on probing, probing depth, tooth mobility, decayed, missing and filled teeth index (DMFT) and root caries were recorded. Difficulty with eating and sleeping were more frequently reported by T2D cases (23.5% and 16.1%, respectively) than by the controls (10.7% and 5.0%, respectively) (P  0). The corresponding ORs were 1.23 (1.01-4.89) and 2.10 (1.08-4.09), respectively. Participants with low consumption of meat and vegetables were more likely than their counterparts with high consumption to report any oral impact. The corresponding ORs were 0.46 (0.25-0.83) and 0.38 (0.17-0.87), respectively. There was a significant interaction between diabetic status and meat consumption as well as between diabetic status and bread consumption. Oral impacts were more frequently reported in T2D cases than controls. Independent of diabetic- and oral clinical status, dietary habits discriminated between individuals with and without oral impacts. The influence of meat and bread consumption on OIDP varied significantly according to T2D status.

    The causal association between human papillomavirus (HPV) and oral squamous cell carcinoma (OSCC) remains controversial. Most of previous studies did not consider the potential modification effect of sexual behaviors when evaluating the role of HPV infection in OSCC risk. To explore the independent and joint effects of oral HPV infection and sexual behaviors on OSCC in Chinese population. A case-control study was conducted from September 2012 to September 2015 in Fujian, China. HPV DNA genotypes were detected in tumor tissues of 178 OSCC patients and oral exfoliated cells of 189 frequency-matched controls using flow-through hybridization and gene chip. Epidemiologic data were collected with a structured questionnaire by face-to-face interviews. Odds ratios (ORs) and 95% confidence interval (CI) were estimated with unconditional logistic regression models. The overall HPV prevalence was 14.04% in OSCC patients and 3.17% in controls. HPV-18 was the most prevalent type in cases and controls (10.67% vs. 2.12%). Oral HPV infection was strongly associated with an increased risk of OSCC: the ORs were 7.21 (95% CI: 2.61-19.88) for HPV16/18 and 7.59 (95% CI: 2.34-24.64) for HPV-18. Moreover, the significant associations were only observed in females, young adults, married population, merchants, non-smokers, non-alcohol drinkers and non-tea drinkers. Additionally, the first intercourse below 22years of age and oral sex practice did not show an association with OSCC. But there was a significantly multiplicative interaction between HPV 16/18 and age at first intercourse for OSCC (P interaction factor for OSCC in Fujian area. Furthermore, there might be a combined effect of HPV 16/18 and age at first intercourse on OSCC. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available The syndrome of hyperandrogenism, insulin resistance, and acanthosis nigricans (HAIR-AN is a subphenotype of the polycystic ovary syndrome. It is one of the most common causes of menstrual problems, hyperandrogenic symptoms, and insulin resistance among young women. Review of clinical data in an outpatient adolescent clinic showed that of the 1,002 young women (ages 10—21 years attending the clinic over a 2-year period, 50 (5% were diagnosed with HAIR-AN syndrome. Mean age of the patients was 15.5, initial mean weight at diagnosis was 94.5 kg, and the mean BMI was 33.33 kg/m2. Patients were treated with a weight-stabilization and -reduction program, oral contraceptive pills, and in most cases metformin. Of the patients, 80% were compliant with the follow-up and treatment regimen, 60% maintained or reduced their weight, 95% had regular menstrual cycles, and in most patients, the acne and/or hirsutism were the same or better than at the start of treatment. We conclude that HAIR-AN syndrome is a common disease in young women and multifaceted, aggressive treatment appears to be effective in reducing the severity of symptoms and preventing further consequences.

  7. Pitfalls in comparing modern hair and fossil bone collagen C and N isotopic data to reconstruct ancient diets: a case study with cave bears (Ursus spelaeus).

    Stable isotope analyses provide one of the few means to evaluate diet of extinct taxa. However, interpreting isotope data from bone collagen of extinct animals based on isotopic patterns in different tissues of modern animal proxies is precarious. For example, three corrections are needed before making comparisons of recent hair and ancient bone collagen: calibration of carbon-13 variations in atmospheric CO2, different isotopic discrimination between diet-hair keratin and diet-bone collagen, and time averaging of bone collagen versus short-term record in hair keratin. Recently, Robu et al. [Isotopic evidence for dietary flexibility among European Late Pleistocene cave bears (Ursus spelaeus). Can J Zool. 2013;91:227-234] published an article comparing extant carbon (δ(13)C) and nitrogen (δ(15)N) stable isotopic data of European cave bear bone collagen with those of Yellowstone Park grizzly bear hair in order to test the prevailing assumption of a largely vegetarian diet among cave bears. The authors concluded that cave bears were carnivores. This work is unfortunately unfounded as the authors failed to consider the necessary corrections listed above. When these corrections are applied to the Romanian cave bears, these individuals can be then interpreted without involving consumption of high trophic-level food, and environmental changes are probably the reason for the unusual isotopic composition of these cave bears in comparison with other European cave bears, rather than a change of diet. We caution researchers to pay careful attention to these factors when interpreting feeding ecology of extinct fauna using stable isotope techniques.

    Motor neuron disease is a devastating neurodegenerative condition, with the majority of sporadic, non-familial cases being of unknown etiology. Several epidemiological studies have suggested that occupational exposure to chemicals may be associated with disease pathogenesis. We report the case of a patient developing progressive motor neuron disease, who was chronically exposed to pesticides and organic solvents. The patient presented with leg spasticity and developed gradually clinical signs suggestive of amyotrophic lateral sclerosis, which was supported by the neurophysiologic and radiological findings. Our report is an evidence based case of combined exposure to organochlorine (DDTs), organophosphate pesticides (OPs) and organic solvents as confirmed by laboratory analysis in samples of blood and hair confirming systematic exposure. The concentration of non-specific dialkylphosphates metabolites (DAPs) of OPs in hair (dimethyphopshate (DMP) 1289.4 pg/mg and diethylphosphate (DEP) 709.4 pg/mg) and of DDTs (opDDE 484.0 pg/mg, ppDDE 526.6 pg/mg, opDDD 448.4 pg/mg, ppDDD + opDDT 259.9 pg/mg and ppDDT 573.7 pg/mg) were considerably significant. Toluene and n-hexane were also detected in blood on admission at hospital and quantified (1.23 and 0.87 μg/l, respectively), while 3 months after hospitalization blood testing was found negative for toluene and n-hexane and hair analysis was provided decrease levels of HCHs, DDTs and DAPs. -- Highlights: ► Exposure to pesticides and organic solvents might be a risk factor for sporadic MND. ► We report a patient who developed progressive upper and lower motor neuron disease. ► The patient had a history of occupational exposure to pesticides and solvents. ► High DDTs’ levels and increased levels of DMP and DEP were measured in his hair. ► The patients’ exposure to chemicals might have played a role in MND development.

    The current work examined a consecutive series of patients presenting vascular malformations (VMs) and venous lakes (VLs) of the lip and oral mucosa who were treated with transmucosal diode laser applications and assessed over a 1 year period. Fifty-nine patients (31 males and 28 females) presenting low-flow VMs or VLs of the oral cavity were treated transmucosally using a diode laser (with an 830 nm operating wavelength and 1.6 W output power) with a 320 µm diameter flexible fiber. All the lesions were assessed 7 days, 30 days, and 1 year after the laser treatment, and the lesion reduction percentage was scored on a one to five scale. The patients were also asked to assess their pain perception daily during the 7 days following the treatment using a visual analog scale (VAS). There were no procedure-related intra- or post-operative complications; only modest pain intensity was reported. Thirty days after the treatment, lesion reduction was described as excellent or good in 52 cases; it was fair or poor in 7. Six patients (F:M ratio 2:4) required a second diode laser application. At the 1 year follow-up, volume reduction was complete in 48 out of 59 patients; there were five recurrences (F:M ratio 3:2). No relevant gender-related differences were noted. The use of diode laser application to treat small oral VMs and VLs was associated to shorter operating times and fewer postoperative complications with respect to the scapel surgery approach. More than one session may nevertheless be required if the anomaly is larger than 10 mm. Lasers Surg. Med. 50:111-116, 2018. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    Hair loss can have major psychological consequences. It can be due to a wide variety of causes, including hormonal disorders, dietary factors, infections, inflammation, trauma, emotional factors, and cancer. Drugs can also induce hair loss, by interacting with the hair growth cycle. Drug-induced hair loss may be immediate or delayed, sudden or gradual, and diffuse or localised. It is usually reversible after drug discontinuation. The drugs most often implicated in hair loss are anticancer agents, interferon, azole antifungals, lithium, immunosuppressants, and many other drugs belonging to a variety of pharmacological classes.

These publications describe 3 interventions that focused on: reducing paediatric tooth decay by educating families and communities; providing dental chemotherapeutics to pregnant women; and training mid-level dental care providers. While these approaches have the potential to improve the oral health of Alaska Native children, there are unique challenges regarding intervention acceptability, reach and sustainability. A case study and conceptual model are presented on multilevel strategies to reduce SSB intake among Alaska Native children. Conclusions. Few oral health interventions have been tested within Alaska Native communities. Community-centred multilevel interventions

    Full Text Available An ectopic tonsil is defined as tonsillar tissue that develops in areas outside of the four major tonsil groups: the palatine, lingual, pharyngeal, and tubal tonsils. The occurrence of tonsillar tissue in the oral cavity in ectopic locations, its prevalence, and its developmental mechanisms that belong to its formation remain unclear. In this report, we describe a rare case of bilateral symmetric ectopic oral tonsillar tissue located at the ventral surface of the tongue along with two solitary cases arising from the floor of the mouth. The role of immune system and its aberrant response leading to ectopic deposits desires further studies. As an ectopic tonsil may simulate a benign soft tissue tumor, this case series highlights the importance of this entity in our clinical differential diagnosis of oral soft tissue masses.

    Idiopathic cerebral sinus thrombosis (CST) can cause death and serious neurological disability. It is unknown whether smoking, a major risk factor for arterial stroke, is a risk factor also for CST. This work explored the association between smoking and CST in a hospital-based, multicentric, case-control study. In order to avoid the confounding effect of the different risk factors for CST, we analysed the homogeneous subgroup of oral contraceptive users. We compared the prevalence of smoking in a group of 43 young women with CST (cases), whose oral contraceptive use was the only known risk factor, with a sample of 255 healthy contraceptive users of similar age (controls). The prevalence of smoking in cases and controls was similar (26% vs. 29%). The age and geographic area-adjusted odds ratio was 0.9; 95% confidence interval, 0.4-1.8; p=0.7. Smoking in oral contraceptive users does not appear to be associated with CST.

  20. ORAL MUCOSA DAMAGE BECAUSE OF HYPOCHLORITE ACCIDENT – A CASE REPORT AND LITERATURE REVIEW

    Full Text Available Background Hypochlorite solution is widely used in dental practice during root canal treatment. Although it is generally regarded as being very safe, potentially severe complications can occur when it comes into contact with soft tissue especially due to its cytotoxic features. Objective The aim of our paper is to present a case of damage of oral mucosa because of leakage of 3% hypochlorite through rubber dam during endodontic treatment. Material and methods We present a 31 years old female with necrosis of buccal mucosa during the endodontic treatment of 46. Results Three days after the procedure the patient was referred to our department for consultation and treatment. Antiseptic lavage was performed and oral antibiotic was administrated. After 5 days intraoral examination showed signs of almost full recovery. Conclusion The need for proper tooth isolation during restorative procedures is obvious. Anything that obscures the operative field negatively impacts operator efficiency and effectiveness. Visibility, patient/operator safety, infection control and the physical properties of dental materials are all compromised when proper isolation is lacking.

    The purpose of the case report was to describe the treatment of a 4(1/2)-year-old boy with amelogenesis imperfect (AI) in the primary dentition. AI is a hereditary condition that affects the development of enamel, causing quantity, structural, and compositional anomalies involving all dentitions. Consequently, the effects can extend to both the primary and secondary dentitions. A 4(1/2)-year-old boy was brought to the dental clinic complaining of tooth hypersensitivity during meals. The medical history and clinical examination were used to arrive at the diagnosis of amelogenesis imperfecta. The treatment was oral rehabilitation of the primary molars with stainless steel crowns and resin-filled celluloid forms of both maxillary and mandibular primary incisors and canines. Improvements in the patient's psychological behavior and the elimination of tooth sensitiveness were observed, and the reestablishment of a normal occlusion resulted in improved eating habits. The child was monitored in the Pediatric Dentistry Clinic at four-month intervals until the mixed dentition stage. The oral rehabilitation of young children with AI is necessary to reestablish the stomatognathic system function, so important for a child's systemic health. An adequate medical history and a careful clinical examination were essential for a correct diagnosis. Treatment was rendered that was appropriate for the child's age and clinical/psychological characteristics. Cost-effective restorative techniques involving stainless steel and composite-resin crowns are shown for the restoration of a young patient with amelogensis imperfecta.

    In 1987 the Swedish Dental Act was amended to allow Swedish dentists who have undergone a specific accreditation course to administer intra-venous sedation. Midazolam is a benzodiazepin derivate with express sedative and hypnotic qualities, powerful amnesia, a short half-life time and few secondary effects. From 1989-1994 midazolam intravenous conscious sedation (ICS) was administered in 372 cases in the Department of Oral and Maxillofacial Surgery, County Hospital, Falun. This study presents data on the 298 patients. Although surgical removal of impacted wisdom teeth predominated, implant surgery, reduction of fractures and correction of anomalies were also carried out. Supplementary sedative premedication was rarely used. Most patients were treated under local anaesthesia. The mean dosage was 10.45 mg (range 1.25-40 mg). Mean dosage/kg was 0.15 mg (range 0.03-0.50 mg). The average duration of anaesthesia was 50 minutes. The average recovery time was 94 minutes. Three hundred and sixty-nine of 372 planned treatments were completed. No serious complications occurred. The patients were co-operative during surgery and were satisfied with the treatment. Compared with full anaesthesia this method required less resources and is a valuable complement in management of anxious patients undergoing oral surgery.

  3. Female pattern hair loss

    Full Text Available Female pattern hair loss (FPHL is a common cause of hair loss in women characterized by diffuse reduction in hair density over the crown and frontal scalp with retention of the frontal hairline. Its prevalence increases with advancing age and is associated with significant psychological morbidity. The pathophysiology of FPHL is still not completely understood and seems to be multifactorial. Although androgens have been implicated, the involvement of androgen-independent mechanisms is evident from frequent lack of clinical or biochemical markers of hyperandrogenism in affected women. The role of genetic polymorphisms involving the androgen and estrogen receptors is being increasingly recognized in its causation and predicting treatment response to anti-androgens. There are different clinical patterns and classifications of FPHL, knowledge of which facilitates patient management and research. Chronic telogen effluvium remains as the most important differential diagnosis. Thorough history, clinical examination, and evaluation are essential to confirm diagnosis. Patients with clinical signs of androgen excess require assessment of biochemical parameters and imaging studies. It is prudent to screen the patients for metabolic syndrome and cardiovascular risk factors. The treatment comprises medical and/or surgical modalities. Medical treatment should be initiated early as it effectively arrests hair loss progression rather than stimulating regrowth. Minoxidil continues to be the first line therapy whereas anti-androgens form the second line of treatment. The progressive nature of FPHL mandates long-term treatment for sustained effect. Medical therapy may be supplemented with cosmetic concealment in those desirous of greater hair density. Surgery may be worthwhile in some carefully selected patients.

  4. Black Hole's 1/N Hair

    According to the standard view classically black holes carry no hair, whereas quantum hair is at best exponentially weak. We show that suppression of hair is an artifact of the semi-classical treatment and that in the quantum picture hair appears as an inverse mass-square effect. Such hair is predicted in the microscopic quantum description in which a black hole represents a self-sustained leaky Bose-condensate of N soft gravitons. In this picture the Hawking radiation is the quantum depletion of the condensate. Within this picture we show that quantum black hole physics is fully compatible with continuous global symmetries and that global hair appears with the strength B/N, where B is the global charge swallowed by the black hole. For large charge this hair has dramatic effect on black hole dynamics. Our findings can have interesting astrophysical consequences, such as existence of black holes with large detectable baryonic and leptonic numbers.

    Full Text Available Abstract Background Suppression of immune system in treated cancer patients may lead to secondary infections that obviate the need of antibiotics. In the present study, an attempt was made to understand the occurrence of secondary infections in immuno-suppressed patients along with herbal control of these infections with the following objectives to: (a isolate the microbial species from the treated oral cancer patients along with the estimation of absolute neutrophile counts of patients (b assess the in vitro antimicrobial activity medicinal plants against the above clinical isolates. Methods Blood and oral swab cultures were taken from 40 oral cancer patients undergoing treatment in the radiotherapy unit of Regional Cancer Institute, Pt. B.D.S. Health University, Rohtak, Haryana. Clinical isolates were identified by following general microbiological, staining and biochemical methods. The absolute neutrophile counts were done by following the standard methods. The medicinal plants selected for antimicrobial activity analysis were Asphodelus tenuifolius Cav., Asparagus racemosus Willd., Balanites aegyptiaca L., Cestrum diurnum L., Cordia dichotoma G. Forst, Eclipta alba L., Murraya koenigii (L. Spreng. , Pedalium murex L., Ricinus communis L. and Trigonella foenum graecum L. The antimicrobial efficacy of medicinal plants was evaluated by modified Kirby-Bauer disc diffusion method. MIC and MFC were investigated by serial two fold microbroth dilution method. Results Prevalent bacterial pathogens isolated were Staphylococcus aureus (23.2%, Escherichia coli (15.62%, Staphylococcus epidermidis (12.5%, Pseudomonas aeruginosa (9.37%, Klebsiella pneumonia (7.81%, Proteus mirabilis (3.6%, Proteus vulgaris (4.2% and the fungal pathogens were Candida albicans (14.6%, Aspergillus fumigatus (9.37%.

    Lichen planus (LP) is a relatively common mucocutaneous disease with autoimmune etiology. Considering its malignancy potential, it is important to define the correct diagnosis, treatment, and clinical follow-up for patients with LP so that the disease is not diagnosed late, thus hindering the chances of curing the disease. This study aims to describe a clinical case of oral squamous cell carcinoma, potentially originated from LP. The patient is undergoing clinical and histopathological follow-up. A 64-year-old Caucasian male patient presented with a proliferative verrucous lesion on the tongue and sought treatment at the School of Dentistry, University of Passo Fundo (UPF), Passo Fundo, Brazil. He claimed the lesion had been present since 1988, and had been initially diagnoses as "oral lichen planus." The physical exam presented three diagnostic hypotheses: plaque-like oral LP, verrucous carcinoma, and squamous cell carcinoma. After incisional biopsy and histopathological analysis, squamous cell carcinoma was diagnosed, probably originating from oral LP. The case study shows that malignancy from oral LP is possible, which justifies periodic clinical and histopathological follow-up, as well as the elimination of risk factors for carcinoma in patients with oral LP.

    We describe three cases of hair loss in a female pattern hair loss (FPHL) distribution with histologic features of lichen planopilaris (LPP). All patients had a history of diffuse, gradual hair loss in a Christmas tree pattern that clinically presented as FPHL on gross and dermoscopic examination. Notably, there were no characteristic clinical signs of LPP and no histologic features of FPHL. These cases are most consistent with cicatricial pattern hair loss (CPHL). This relatively new entity is similar to fibrosing alopecia in a pattern distribution (FAPD) in that they are both scarring alopecias confined to a FPHL distribution, but CPHL lacks the clinical signs of perifollicular erythema and perifollicular keratosis seen in FAPD. These three cases may present an early, subtle form of CPHL and will be of interest to clinicians and histopathologists alike. © 2017 The Australasian College of Dermatologists.

    Cancer of the oral cavity is of growing concern worldwide. In the Micronesia, there has been a recent increase in use of betel nut and tobacco chewing in addition to already existing problem of smoking and alcohol drinking. These deleterious habits have further added the risk for development of oral cancers in the Marshall Islands. The oral cancers have good prognosis, which is directly related to the early diagnosis and treatment. Advanced staged cancers need mutilating surgery in addition to radiotherapy and carry high mortality rate. The epidemiology, etiology and recent approaches in the management of oral cavity cancer has been discussed along with a case report of advanced cancer of the floor of the mouth from the Marshall Islands.

    Full Text Available BACKGROUND: Killed oral cholera vaccines (OCVs are available but not used routinely for cholera control except in Vietnam, which produces its own vaccine. In 2007-2008, unprecedented cholera outbreaks occurred in the capital, Hanoi, prompting immunization in two districts. In an outbreak investigation, we assessed the effectiveness of killed OCV use after a cholera outbreak began. METHODOLOGY/PRINCIPAL FINDINGS: From 16 to 28 January 2008, vaccination campaigns with the Vietnamese killed OCV were held in two districts of Hanoi. No cholera cases were detected from 5 February to 4 March 2008, after which cases were again identified. Beginning 8 April 2008, residents of four districts of Hanoi admitted to one of five hospitals for acute diarrhea with onset after 5 March 2008 were recruited for a matched, hospital-based, case-control outbreak investigation. Cases were matched by hospital, admission date, district, gender, and age to controls admitted for non-diarrheal conditions. Subjects from the two vaccinated districts were evaluated to determine vaccine effectiveness. 54 case-control pairs from the vaccinated districts were included in the analysis. There were 8 (15% and 16 (30% vaccine recipients among cases and controls, respectively. The vaccine was 76% protective against cholera in this setting (95% CI 5% to 94%, P = 0.042 after adjusting for intake of dog meat or raw vegetables and not drinking boiled or bottled water most of the time. CONCLUSIONS/SIGNIFICANCE: This is the first study to explore the effectiveness of the reactive use of killed OCVs during a cholera outbreak. Our findings suggest that killed OCVs may have a role in controlling cholera outbreaks.

    Background A 43-year-old female patient presented with a chief complaint of upper abdominal pain. As her complaints had lasted for 1 month, an upper gastrointestinal system endoscopy was performed and discovered a bezoar in the stomach. Case presentation The bezoar was quite hard and light green-yellow in color. Pathological examination revealed phytobezoar. The patient was hospitalized and given oral Coca-Cola® Zero for seven days at a dose of 500 mL three times daily. Conclusion The upper gastrointestinal system endoscopy performed at the end of 7 days showed that the phytobezoar had softened and become smaller. The phytobezoar was broken into pieces with biopsy forceps and washing was applied, so the phytobezoar pieces could pass through the pylorus. The patient was discharged after the procedure without problem. PMID:22393302

    Allgrove syndrome, also known as Triple A syndrome, is a rare autosomal recessive genetic disease characterized by three signs: esophageal achalasia, adrenocorticotropic hormone refractoriness, and alacrima. A 31-year-old male presented to our hospital for treatment of difficulty swallowing caused by esophageal achalasia. Because he had complicating alacrima, a neurologic disease, and a family history of consanguineous marriage, a genetic neurologic disease was suspected. Then, a mutation in the achalasia-addisonianism-alacrima syndrome gene was identified. With the diagnosis of Allgrove syndrome, a per-oral endoscopic myotomy (POEM) was performed for esophageal achalasia. After the POEM, the symptoms and the esophageal pressure findings ameliorated quickly, with no recurrence noted throughout a follow-up of more than 1 year. Here, we report the first case of POEM performed for esophageal achalasia in Allgrove syndrome.

    Full Text Available Introduction: Radiation, commonly employed as neoadjuvant, primary, and adjuvant therapy for head and neck cancer causes numerous epithelial and stromal changes, prominent among which is fibrosis with its early and late consequences. Very little is known about the true nature of the fibrosed tissue and the type of fibers accumulated. Radiotherapy affects the supporting tumor stroma often resulting in a worsening grade of tumor post-radiation. Aim: To study epithelial, neoplastic, stromal, and glandular changes in oral cavity induced by radiation therapy for oral squamous cell carcinoma (OSCC using special stains. Materials and Methods: The study included 27 samples of recurrent OSCC following completion of radiotherapy (recurrence within an average span of 11 months, and 26 non-irradiated cases of OSCC. Patients with a history of combined radiotherapy and chemotherapy were not included in the study. The epithelial changes assessed included epithelial atrophy, apoptosis, necrosis, dysplasia, and neoplasia. The connective tissue was evaluated for amount of fibrosis, quality of fibers (using picrosirius red staining, fibrinous exudate, necrosis, pattern of invasion, vessel wall thickening, and salivary gland changes. The aforementioned changes were assessed using light and polarizing microscopy and tabulated. Statistical Analysis: Epithelial and connective tissue parameters were compared between the irradiated and non-irradiated cases using chi square and t-tests. Results: Epithelial and connective tissue parameters were found to be increased in irradiated patients. Pattern of invasion by tumor cells varied from strands and  cords between the two groups studied. The effect of radiation was seen to reflect on the maturity of fibers and the regularity of their distribution.

    Sociological analysis of advertising reveals the currently operative body codes within a society, and more fundamentally, depicts the (ideal) relationships between men and women, between generations, and so on. To demonstrate that sports advertising based largely on trichological stereotypes. The idealised portrayal of human relations in advertisements (N=700) taken from French magazines was analysed by means of systematic coding and use of analytical software. This approach allowed characterisation of each advertisement in relation to the entire sample, with identification of significant elements (dominant colour, stature of models, setting, etc.), and determination of frequency of appearance and occurrence as well as testing of dependency relations. There were significant differences in the portrayal of men and women in advertisements. In the 700 advertisements in the series we examined, male subjects very often had short hair (231 cases, 33%) or shaved heads (33 cases, 4.7%) while women were shown with long hair, either free (80 cases) or tied (73 cases). Women with short hair were rarely portrayed (4.3%), as were men with long hair (42 cases, 6%). Above all, with the exception of eyebrows and eyelashes, no other body hair was seen in male and female athletic figures in 238 advertisements, being visible in only 60 cases (8.6%). Facial stubble, and more particularly beards and moustaches, was fairly infrequent, despite the omnipresence of male models. The majority of advertising situations involving sporting figures show clear stereotyping. Body hair is a pertinent pointer to understanding of contemporary sports models. A clear overall male/female distinction was present throughout. Men were presented in these adverts as active figures, leaders, etc. while women tended to be passive, spectators, and in some cases, admiring onlookers. A degree of confusion between genders was noticeable as a result of the shaving and depilation trends currently in vogue in the

    The complaint of hair loss is quite frequent but merits close attention because it can be very stressful to the patient. A simple examination will allow in most cases to define the origin of the hair loss and reassure the patient rapidly as to its likely evolution if it is reversible. The examination must take into account the medical, chirurgical, gynaecological and dietary antecedents and the cosmetic habits. These elements must be situated in time and complemented by a clinical examination to define the loss as diffuse or localised and in the latter case, expose scar damage. The clinical examination will be associated with a trichogram and in certain cases with a biopsy or a squam prelevement. Further, the blood can be analysed for different metabolically and hormonal elements. Finally, the treatments already administered must be known in order to identify the beneficial and secondary effects, which will allow the definition of a new treatment, if required.

    Oral lichen planus is a chronic inflammatory mucocutaneous disease. Topical use of steroids and other immuno-modulating therapies have been tried for this intractable condition. Nowadays, tacrolimus ointment is used more commonly as a choice for treatment. However, a number of discussions have taken place after tacrolimus was reported to be carcinogenic. This report describes a patient who applied tacrolimus ointment to the lower lip after being diagnosed with oral lichen planus in 2008, and whose lesion developed squamous cell carcinoma in 2010. Since the relationship between tacrolimus and cancer development has been reported in only a few cases, including this case report, the clinician must be careful selecting tacrolimus as a second-line treatment for oral lichen planus.

    Full Text Available People use the language constantly without realizing how valuable it is. The oral language is a basic tool, it is necessary and it is so used that few people stop to think about its complexity, its essence, or its great power. The educational stages of Compulsory Secondary Education and Baccalaureate are essential for the development and improvement of oral skills (speaking and listening. It is about two stages in which students get prepared for later autonomous development in «adult life», so it is a key moment to carry out a correct acquisition and teaching of the suitable use of oral skills. Therefore, it may be deduced that the teachers of any subject in these educational stages, and their conceptions about general didactics, play a fundamental role in teaching and assessment of oral skills. This paper is aimed to present a qualitative research in which the case study will be done through the clinical interview in order to study in depth teachers’ conceptions about teaching and didactics of the oral language of the educational stages that we deal.. Thus, we will analyze the data obtained and we will take the didactic proposals used by teachers interviewed as a starting point to propose a model of action and improvement of the teaching-learning process of oral language in the classrooms of these educational stages.

    Recently, various examples of asymptotically flat, rotating black holes (BHs) with synchronized hair have been explicitly constructed, including Kerr BHs with scalar or Proca hair, and Myers–Perry BHs with scalar hair and a mass gap, showing there is a general mechanism at work. All these solutions have been found numerically, integrating the fully non-linear field equations of motion from the event horizon outwards. Here, we address the spacetime geometry of these solutions inside the event horizon. Firstly, we provide arguments, within linear theory, that there is no regular inner horizon for these solutions. Then, we address this question fully non-linearly, using as a tractable model five dimensional, equal spinning, Myers–Perry hairy BHs. We find that, for non-extremal solutions: (1) the inside spacetime geometry in the vicinity of the event horizon is smooth and the equations of motion can be integrated inwards; (2) before an inner horizon is reached, the spacetime curvature grows (apparently) without bound. In all cases, our results suggest the absence of a smooth Cauchy horizon, beyond which the metric can be extended, for hairy BHs with synchronized hair.

    2013-01-01

    Context: Female pattern hair loss (FPHL) also known as female androgenetic alopecia is a common condition afflicting millions of women that can be cosmetically disrupting. Prompt diagnosis and treatment are essential for obtaining optimal outcome. This review addresses the clinical presentation of female pattern hair loss, its differential diagnosis and treatment modalities. Evidence Acquisition: A) Diffuse thinning of the crown region with preservation of the frontal hairline (Ludwig’s type) B) The “Christmas tree pattern” where the thinning is wider in the frontal scalp giving the alopecic area a triangular shaped figure resembling a christmas tree. C) Thinning associated with bitemporal recession (Hamilton type). Generally, FPHL is not associated with elevated androgens. Less commonly females with FPHL may have other skin or general signs of hyperandrogenism such as hirsutism, acne, irregular menses, infertility, galactorrhea and insulin resistance. The most common endocrinological abnormality associated with FPHL is polycystic ovarian syndrome (PCOS). Results: The most important diseases to consider in the differential diagnosis of FPHL include Chronic Telogen Effluvium (CTE), Permanent Alopecia after Chemotherapy (PAC), Alopecia Areata Incognito (AAI) and Frontal Fibrosing Alopecia (FFA). This review describes criteria for distinguishing these conditions from FPHL. Conclusions: The only approved treatment for FPHL, which is 2% topical Minoxidil, should be applied at the dosage of 1ml twice day for a minimum period of 12 months. This review will discuss off-label alternative modalities of treatment including 5-alfa reductase inhibitors, antiandrogens, estrogens, prostaglandin analogs, lasers, light treatments and hair transplantation.

    To support clinical researchers, librarians and informationists may need search filters for particular tasks. Development of filters typically depends on a "gold standard" dataset. This paper describes generalizable methods for creating a gold standard to support future filter development and evaluation using oral squamous cell carcinoma (OSCC) as a case study. OSCC is the most common malignancy affecting the oral cavity. Investigation of biomarkers with potential prognostic utility is an active area of research in OSCC. The methods discussed here should be useful for designing quality search filters in similar domains. The authors searched MEDLINE for prognostic studies of OSCC, developed annotation guidelines for screeners, ran three calibration trials before annotating the remaining body of citations, and measured inter-annotator agreement (IAA). We retrieved 1,818 citations. After calibration, we screened the remaining citations (n = 1,767; 97.2%); IAA was substantial (kappa = 0.76). The dataset has 497 (27.3%) citations representing OSCC studies of potential prognostic biomarkers. The gold standard dataset is likely to be high quality and useful for future development and evaluation of filters for OSCC studies of potential prognostic biomarkers. The methodology we used is generalizable to other domains requiring a reference standard to evaluate the performance of search filters. A gold standard is essential because the labels regarding relevance enable computation of diagnostic metrics, such as sensitivity and specificity. Librarians and informationists with data analysis skills could contribute to developing gold standard datasets and subsequent filters tuned for their patrons' domains of interest.

    Alexandre Simões Garcia

    2014-01-01

    Full Text Available Inverted Schneiderian papilloma is an uncommon benign tumor that presents tendency to recur and propensity to be associated with malignancy in approximately 10% of the cases. Some of these lesions are isolated in the maxillary sinus, and predominantly affect white males with mean age of 50 years. We report a case of squamous cell carcinoma arising from inverted Schneiderian papilloma in the maxillary sinus extending to the mouth. The patient was submitted to extraction of a maxillary molar tooth four months before the exacerbation of the symptoms of nasal airway obstruction and facial enlargement. Computed tomography scan revealed a sinonasal mass causing opacification of the right maxillary sinus with destruction of the lateral nasal wall and maxillary sinus floor. The patient was referred to an oncology center for treatment and died from tumor progression one year after the cancer was diagnosed. The intention of this report is to alert dentists to include the inverted Schneiderian papilloma, either associated with squamous cell carcinoma, or not, in the differential diagnosis of maxillary sinus tumors with aggressive behavior, which may extend to the oral cavity or involve roots of teeth.

    Full Text Available Abstract Background Major histocompatibility complex class II deficiency, also referred to as bare lymphocyte syndrome is a rare primary Immunodeficiency disorder characterized by a profondly deficient human leukocyte antigen class II expression and a lack of cellular and humoral immune responses to foreign antigens. Clinical manifestations include extreme susceptibility to viral, bacterial, and fungal infections. The infections begin in the first year of life and involve usually the respiratory system and the gastrointestinal tract. Severe malabsorption with failure to thrive ensues, often leading to death in early childhood. Bone marrow transplantation is the curative treatment. Case reports Here we report two cases with a late outcome MHC class II deficiency. They had a long term history of recurrent bronchopulmonary and gastrointestinal infections. Bone marrow transplantation could not be performed because no compatible donor had been identified. At the age of 12 years, they developed oral papillomatous lesions related to HPV (human papillomavirus. The diagnosis of HPV infection was done by histological examination. HPV typing performed on the tissue obtained at biopsy showed HPV type 6. The lesions were partially removed after two months of laser treatment. Conclusions Viral infections are common in patients with MHC class II and remain the main cause of death. Besides warts caused by HPV infection do not exhibit a propensity for malignant transformation; they can cause great psychosocial morbidity.

  8. Bevacizumab with metronomic chemotherapy of low-dose oral cyclophosphamide in recurrent cervical cancer: Four cases

    2018-05-01

    Full Text Available Standard chemotherapy for women with advanced or recurrent cervical cancer involves a combination of paclitaxel, platinum, and bevacizumab. However, for patients who experience anaphylaxis in response to paclitaxel or platinum, have permanent peripheral neuropathy, or develop early recurrence or progressive disease during first-line chemotherapy, the development of a non-taxane non-platinum regimen is mandatory. Clinical trials using anti-angiogenic treatment demonstrated favorable outcomes in cases of highly vascularized cervical cancer. Metronomic chemotherapy has been considered an anti-angiogenic treatment, although its use in combination with bevacizumab has not been studied in cervical cancer. We treated four patients with recurrent cervical cancer with 50 mg of oral cyclophosphamide daily and 15 mg/kg of intravenous bevacizumab every 3 weeks (CFA-BEV. One patient experienced disease progression after 4 months, whereas the other three patients continued the regimen until their last follow-up at 13, 14, and 15 months, respectively. One patient suffered from grade 3 neutropenia; however, no grade 2 or higher non-hematological toxicities were observed. These cases demonstrate the use of CFA-BEV with minimal toxicity and expected anti-cancer activity and indicate that this regimen should be considered for second-line chemotherapy in advanced recurrent cervical cancer.

    Diet and inflammation have been suggested to be important risk factors for oral and pharyngeal cancer. We examined the association between dietary inflammatory index (DII™) and oral and pharyngeal cancer in a large case-control study conducted between 1992 and 2009 in Italy. This study included 946 cases with incident, histologically confirmed oral and pharyngeal cancer, and 2,492 controls hospitalized for acute non-neoplastic diseases. The DII was computed based on dietary intake assessed by a valid 78-item food frequency questionnaire and was adjusted for nonalcohol energy intake using the residual approach (E-DII™). Logistic regression models were used to estimate odds ratios (ORs), and 95% confidence intervals (CIs), adjusted for age, sex, non-alcohol energy intake, study center, year of interview, education, body mass index, tobacco smoking, and alcohol drinking. Subjects with higher DII scores (i.e., with a more pro-inflammatory diet) had a higher risk of oral and pharyngeal cancer, the OR being 1.80 (95% CI 1.36-2.38) for the highest versus the lowest DII quartile and 1.17 (95% CI 1.10-1.25) for a one-unit increase (8% of the DII range). When stratified by selected covariates, a stronger association was observed among women (OR quartile4 v.1 3.30, 95% CI 1.95-5.57). We also observed a stronger association for oral cancers and a strong combined effect of higher DII score and tobacco smoking or alcohol consumption on oral and pharyngeal cancer. These results indicate that the pro-inflammatory potential of the diet, as shown by higher DII scores, is associated with higher odds of oral and pharyngeal cancer. © 2017 UICC.

    2014-06-01

    Full Text Available Hair is a primary characteristic of mammals, and exerts a wide range of functions including thermoregulation, physical protection, sensory activity, and social interactions. The hair shaft consists of terminally differentiated keratinocytes that are produced by the hair follicle. Hair follicle development takes place during fetal skin development and relies on tightly regulated ectodermal–mesodermal interactions. Hair follicles form during embryonic development and, after birth, undergo recurrent cycling of growth (anagen, apoptosis-driven regression (catagen, and relative quiescence (telogen. As a functional mini-organ, the hair follicle develops in an environment with dynamic and alternating changes of diverse molecular signals. Our molecular understanding of hair follicle biology relies heavily on genetically engineered mouse models with abnormalities in hair structure, growth, and/or pigmentation and significant advances have been made toward the identification of key signaling pathways and the regulatory genes involved. In this review, the basic concepts of hair follicle, a mini-complex organ, biology will be presented and its importance in clinical applications will be summarized.

    Leiomyoma, a benign neoplasia arising from smooth muscle is an uncommon neoplasia of the oral cavity. The most common histological subtype in the oral cavity is the vascular one. To supplement information on vascular leiomyoma of the oral cavity (VLOC), we present cases of VLOC describing their clinical, histological, and immunohistochemical characteristics. Case reports. Five cases of VLOC (3 females; 2 males) from the Clinical and Experimental Pathology Laboratory, Dental School, National Autonomous University of México, are included. The most frequent clinical characteristic of VLOC was a single, asymptomatic, slow growing nodule. The age average of the cases was 40.6, however 3 out of our 5 cases were < or = 40 years old at the moment of their diagnosis. The lesions were composed of fusiform cells arranged in bundles or fascicles. The neoplastic cells were characterized by eosinophilic cytoplasm and tapered nuclei. The presence of vascular spaces was prominent in all cases. The immunocharacteristics of VLOC neoplastic cells were: alpha smooth muscle (+); vimentin (+), desmin (+), CD34 (-) and S-100 protein (-). The endothelial cells of vascular spaces were CD34 (+). Differential diagnosis of VLOC with fusocellular neoplasm is discussed.

    2013-01-01

    Full Text Available Oral squamous papilloma is a benign proliferation of the stratified squamous epithelium, which results in a papillary or verrucous exophytic mass induced by human papilloma virus (HPV. These oral mucosa lesions are most often asymptomatic and have small progression. Laser assisted surgery is common nowadays with several advantages including successful hemostasis, devoid of sutures, wound sterilization and minimal post-operative pain and edema. The aim of this report is to present the oral squamous papilloma in a pediatric patient and its treatment with soft tissue laser. The lesion was excised with diode laser and the healing was uneventful in follow-up visit after one year. Oral squamous papillomas can be found in child′s oral cavity and laser dentistry can be used by dental clinicians to treat these kinds of oral lesions and should be considered as an alternative to conventional surgery.

    A 40-year-old woman experiencing sudden dyspnea went to her personal doctor for advice. She was previously diagnosed with endometriosis and prescribed oral contraceptives for treatment. During earthquakes, she spent 7 nights sleeping in a vehicle. The patient had swelling and pain in her left leg and high D-dimer concentration levels. A contrast-enhanced computed tomography scan revealed a contrast deficit in the bilateral pulmonary artery and in the left lower extremity. She was diagnosed with pulmonary thromboembolism (PTE), and anticoagulation therapy was initiated. This present case is the first report of PTE attributed to the use of oral contraceptives after earthquakes.

    A normally hearing left-handed patient familiar with American Sign Language (ASL) was assessed under sodium amytal conditions and with left cortical stimulation in both oral speech and signed English. Lateralization was mixed but complementary in each language mode: the right hemisphere perfusion severely disrupted motoric aspects of both types of language expression, the left hemisphere perfusion specifically disrupted features of grammatical and semantic usage in each mode of expression. Both semantic and syntactic aspects of oral and signed responses were altered during left posterior temporal-parietal stimulation. Findings are discussed in terms of the neurological organization of ASL and linguistic organization in cases of early left hemisphere damage.

    2017-09-01

    Migraine headache is a primary neurologic disease affecting millions of people worldwide. As a consequence, quality of life is diminished, productivity suffers (through loss of work force), and treatment costs are substantial. The occurrence rate in the general population is quite high, with women accounting for 3 of every 4 cases. Between January 2011 and May 2012, a total of 221 patients received hair transplants. Another 590 patients underwent hair transplantation between June 2012 and December 2016. Initially (first interval), patients were not questioned on migraine headaches in preoperative visits, but questioning was regularly done thereafter. Overall, 150 patients given transplants in the first period were surveyed by phone regarding preoperative migraine headaches. Aside from the 1 incidental discovery, no other instances of migraine emerged. Headache origins were occipital-frontal in 2 patients, occipital-temporal in 2 patients, and occipital-temporal-frontal in the 2 others. Donor/receiver areas in hair transplantation and migraine trigger zones shared locations. Headache frequencies ranged from 4 to 8 days per month (average, 6 days), and pain scores were 5-8 (10 being highest). Duration of pain was 3-5 hours (average, 4 hours). All six patients had used various medications, such as triptans, ergot, and nonsteroidal anti-inflammatory drugs, before hair transplantation. The 1 female patient was a 32-year-old seeking treatment for alopecia, with a 6-year history of migraine headaches. The male patients presenting with androgenetic alopecia (grade 4-5 by Norwood classification) had 6- to 20-year migrainous histories. After hair transplantation, each migraine sufferer was checked once in the first month and then once every 3 months. Those who could not appear in person after the first year were evaluated by phone every 3 months. Migraine headaches had ceased in all 6 patients, none of whom used medical treatments for migraines thereafter. The postoperative

    Full Text Available Griscelli syndrome (GS is a rare autosomal recessive genetic disorder characterized by variable immunodeficiency, partial albinism, abnormal accumulation of melanosomes in melanocytes, pigmentary dilution of the skin, and shiny silver-gray hair. GS has three types, with the first and second types caused by mutations in two genes being located at band 15q21: RAB27A and MYO5A. The expression of the third form of GS is restricted to the characteristic hypopigmentation of GS, and results from mutation in the gene that encodes melanophilin MLPH. It has also been shown that an identical phenotype can result from the deletion of the MYO5A F-exon. The aim of this case report is the presentation of oral and dental features and SEM images of the hair of a 12-year-old girl with GS type 3. [Arch Clin Exp Surg 2015; 4(3.000: 164-167

    2013-01-01

    Sodium valproate is a well-established treatment in epilepsy and mood disorders. Its utility is compromised by its adverse effects such as tremor, weight gain, hair loss, and liver dysfunction. Hair loss may occur when drug is used in higher dose. Drug-induced hair loss is diffused and non-scarring, which is reversible upon withdrawal. But there are no case reports showing relation between serum levels of valproate and occurrence of hair loss. So we took interest in reporting this case report.

    Grisceli syndrome is a rare disease is a rare disease characterized by pigment dilution, partial albinism, variable cellular immunodeficiency and an acute phase of uncontrolled T-lymphocyte macrophage activation. Griscelli et al described this syndrome in 1978. Since then, only approximately, 60 cases have been reported, most from Turkish and Mediterranean population. In microscopic examination, silvery grey hair with large clumped melanosomes on the hair shaft is the diagnostic finding. Here, we present scanning electron microscopic study of hair in 2 cases of Griscelli syndrome where the hair showed normal cuticular pattern but nodular structures were present as an abnormal finding.

    It has been reported that concurrent chemoradiotherapy (CCRT) can result in a superior treatment response and survival outcome compared with radiotherapy alone in patients with squamous cell carcinoma of the head and neck, and it has become the standard of care for locally advanced disease and organ preservation. However, the major limitation to radiotherapy or CCRT is locoregional treatment-related toxicities, particularly oral mucositis (OM). We experienced two cases of pain-uncontrolled OM in which the Traditional Oriental Medicine Hange-shashin-to (TJ-14) was effective. A 44-year-old man with nasopharyngeal carcinoma and neck metastases underwent CCRT and suffered from OM of grade 3 according to the Common Terminology Criteria for Adverse Effects (CTCAE). His pain was uncontrolled with a variety of analgesics, so we prescribed TJ-14 for him as a gargle. Even during CCRT, the pain significantly diminished and OM was improved to grade 1. TJ-14 contributed to completion of CCRT and improvement of the patient's nutrition status. A 67-year-old man with unknown primary and neck metastases underwent neck dissection and adjuvant radiotherapy. During adjuvant radiotherapy, he had OM of grade 3 and was unable to eat, so he was hospitalized and was started to have TJ-14. Although his OM remained grade 3 during the therapy, his pain was alleviated, leading to completion of the treatment. TJ-14 can be an effective supportive therapy for OM caused by radiotherapy.

    While most oral surgical procedures can be safely performed in an outpatient setting, certain medical conditions may present a higher chance of postoperative complications. In particular, those predisposing the patient to bleeding abnormalities pose a potential risk when performing such treatments. The authors report a case involving full-mouth extractions in a patient with cirrhosis and thrombocytopenia after obtaining a platelet transfusion. A 62-year-old Caucasian female presented to a university special care dental clinic requiring extractions. Her pertinent medical history was remarkable for cirrhosis and thrombocytopenia, with a platelet count of 32,000/uL. Upon medical consultation, the patient was appointed for a prophylactic platelet transfusion. The surgery was rendered uneventfully, and the patient achieved adequate hemostasis without hospitalization. Patients with cirrhosis pose a potential bleeding risk with dental surgical procedures. Pre-operative medical consultation, review of pertinent laboratory values, and prophylactic platelet transfusion allow these patients to be managed safely in an outpatient setting. © 2015 Special Care Dentistry Association and Wiley Periodicals, Inc.

    We know of only limited data about the role of oral hygiene and the risk of oral cancer with different standards of education. The aim of this study was to assess the association between oral hygiene and risk of oral cancer, with stratification by standard of education, in Chinese women. We organised a case-control study with 250 women with oral cancer and 996 age-matched controls in Fujian, China. Data were collected by personal interview using a structured questionnaire. We used unconditional logistic regression with stratification by educational standard to estimate the odds ratios (OR) and 95% CI. Tooth-brushing twice a day or more was inversely related to the risk of oral cancer in women with high school education or above (OR 0.50; 95% CI 0.25 to 0.98), but not in those who were illiterate or had primary-middle school education. Wearing dentures showed an increased risk only in less well-educated women: the OR were 2.23 (95% CI 1.14 to 4.34) for the illiterate and 1.68 (95% CI 1.08 to 2.62) for the primary-middle school group. The loss of more than five teeth and oral ulceration were associated with increased risks of oral cancer in all three groups. There was also a multiplicative interaction between oral hygiene and standard of education for risk of oral cancer (p=0.001). Our results suggest that oral hygiene seems to have a critical role in the risk of oral cancer in Chinese women, but this effect may be modified by their educational standard.

    Background Pharmacist's skills are underutilized whilst they are directly involved with antibiotic supply to the community. Addressing this issue could lead to better use of antibiotics and hence decreased resistance. Objective Explore how pharmacists can prescribe oral antibiotics to treat a limited range of infections whilst focusing on their confidence and appropriateness of prescribing. Setting Community pharmacies, Western Australia. Method Data were collected using a self-administered questionnaire also containing case vignettes. These were distributed to a random sample of metropolitan and rural community pharmacies in Western Australia. A Generalised Estimating Equation was used to compare respondents' level of confidence in treating various infections and to assess appropriateness of prescribing. Main outcome measure Appropriateness and confidence of antibiotic prescribing. Results A response rate of 34.2% (i.e. 425 responses to case vignettes) was achieved from 240 pharmacies. There were high levels of confidence to treat simple infections such as uncomplicated UTIs (n = 73; 89.0%), impetigo (n = 65; 79.3%), mild bacterial skin infections (n = 62; 75.6%) and moderate acne (n = 61; 72.4%). Over 80% of respondents were confident to prescribe amoxicillin (n = 73; 89%), trimethoprim (n = 72; 87.8%), amoxicillin and clavulanic acid (n = 70; 85.4%), flucloxacillin (n = 70; 85.4%) and cephalexin (n = 68; 82.9%). High levels of appropriate antibiotic prescribing were shown for uncomplicated UTI (97.2%), cellulitis (98.2%) and adolescent acne (100.0%). Conclusion This study identified key limited infections and antibiotics for which pharmacists were supportive and confident to prescribe. This role could lead to better use of antibiotics in the community and minimisation of resistance.

    Leishmaniasis is an extremely difficult disease to treat. Previously, it was shown that oral Kalanchoe pinnata (Kp) leaf extract is strongly effective against murine leishmaniasis. Here, it is shown that the serum levels of alanine-aminotransferase (ALT), aspartate-aminotransferase (AST), urea and alkaline phosphatase were unchanged in mice orally treated with supraoptimal Kp doses for 30 days, indicating the absence of chronic toxicity to the liver, heart or kidney. Additionally, evidence is presented that human leishmaniasis may also be controlled with oral Kp. A 36-year-old man with an active cutaneous leishmaniasis was orally treated with 30 g wet weight of Kp leaves/day for 14 days. During the Kp treatment, the lesion stopped growing and slightly decreased. No adverse reactions or toxicity was observed. This study reports for the first time that Kalanchoe pinnata contains substances potentially active and safe for the oral treatment of human cutaneous leishmaniasis.

    Color fastness is a major concern for consumers and manufacturers of oxidative hair dye products. Hair dye loss results from multiple wash cycles in which the hair dye is dissolved by water and leaches from the hair shaft. In this study, we carried out a series of measurements to help us better understand the kinetics of the leaching process and pathways associated with its escape from the fiber. Hair dye leaching kinetics was measured by suspending hair in a dissolution apparatus and monitoring the dye concentration in solution (leached dye) with an ultraviolet-visible spectrophotometer. The physical state of dye deposited in hair fibers was evaluated by a reflectance light microscopy technique, based on image stacking, allowing enhanced depth of field imaging. The dye distribution within the fiber was monitored by infrared spectroscopic imaging of hair fiber cross sections. Damage to the ultrafine structure of the hair cuticle (surface, endocuticle, and cell membrane complex) and cortex (cell membrane complex) was determined in hair cross sections and on the hair fiber surface with atomic force microscopy. Using differential scanning calorimetry, we investigated how consecutive coloring and leaching processes affect the internal proteins of hair. Further, to probe the surface properties of hair we utilized contact angle measurements. This study was conducted on both pigmented and nonpigmented hair to gain insight into the influence of melanin on the hair dye deposition and leaching processes. Both types of hair were colored utilizing a commercial oxidative hair dye product based on pyrazole chemistry.

    Use of hair as a biological dosimeter of neutron exposure was proposed a few years ago. To date, the (32)S(n,p)(32)P reaction in hair with a threshold of 2.5 MeV is the best choice to determine the fast neutron dose using body activation. This information is essential with regards to the heterogeneity of the neutron transfer to the organism. This is a very important parameter for individual dose reconstruction from the surface to the deeper tissues. This evaluation is essential to the adapted management of irradiated victims by specialized medical staff. Comparison exercises between clinical biochemistry laboratories from French sites (the CEA and COGEMA) and from the IRSN were carried out to validate the measurement of (32)P activity in hair and to improve the techniques used to perform this examination. Hair was placed on a phantom and was irradiated at different doses in the SILENE reactor (Valduc, France). Different parameters were tested: variation of hair type, minimum weight of hair sample, hair wash before measurement, delivery period of results, and different irradiation configurations. The results obtained in these comparison exercises by the different laboratories showed an excellent correlation. This allowed the assessment of a dose-activity relationship and confirmed the feasibility and the interest of (32)P measurement in hair following fast neutron irradiation.

    Spiral dental implant (SDI) is an implant with a conical internal helix that confers the characteristic of self-drilling, self-tapping, and self-bone condensing. These proprieties offer better control during insertion of SDI giving a high primary stabilization, even in poor quality bone. A shorter diameter of SDI results in reduced drilling during insertion and consequently less trauma and minimal bone loss. To address the research purpose, the investigators designed a retrospective cohort study. The study population was composed of 25 patients, 11 males and 14 females that have been treated by Dr. Balan with 187 SDI positioned in mandible and into maxilla bone. The implants were placed during the years 2013 to 2014 in Dr. Balan clinic. All patients underwent the same surgical protocol. Several variables are investigated: demographic (age and gender), anatomic (upper/lower jaws and tooth site), implant (length and diameter and type) variables, edentulism (partial or total), and comorbid status of health (i.e.: hypothyroidism, parodontitis, hypertension, diabetes, presence of cancer, heart disease, hepatitis and rheumatologic disease). Pearson Chi-Square test was used to investigate variables and p < 0.05 was considered statistically significant. Statistically it has been shown that females have a higher possibility of unsuccessful respect of male, with a "p value" of 0.014. Another important impact factor for success of implant insertion has been represented by concomitants pathologies: cancer represents the most negative high factor risk with a percentage of unsuccessful of 50%, followed by heart disease (15%), and diabetes (3.7%). SDIs are reliable tools for difficult cases of oral rehabilitation. They have a higher success and survival rate, which means stable results over time. No differences were detected among SDI lengths, implant/crown ratio. In addition, the insertion of SDIs in banked bone can be performed without adverse effects. Finally, flapless and

    The aim of this study was to assess the prognostic value of lymph node involvement in patients with squamous cell carcinoma of the oral cavity. Retrospective study of 137 patients with T4 squamous cell carcinoma of the oral cavity treated by surgery and radiotherapy (84 N0, 23 N1, 16 N2,14 N3). Twenty-three patients in the N0 group had a history of surgery or radiotherapy. One hundred fourteen patients underwent limited or radical neck dissection unilaterally or bilaterally. The histological charts were reviewed and correlated with preoperative lymph node clinical stage. The local failure rate and the overall survival curves were calculated with respect to clinical and histological stages. The causes of death were analyzed. No evidence of lymph node metastasis was found in 47.4% of cases (54 of 114 patients). Among the node-positive (N+) patients, 39 had rupture of the lymph node capsule (R+). In the N0 group, 27.8% of patients were N+. Regional control rates after surgery and radiotherapy were 95% at 1 year and 85.4% at 5 years. The local failure rates were 6% in N0, 8.7% in N1, 31.2% in N2, 51.7% in N3, 9% in node-negative (N-), and 29% in N+R+ patients. The overall survival rates at 3 and 5 years were, respectively, 44.7% and 34.8% in the N0 group, 37.7% and 37.7% (same rate at 3 and 5 years) in the N1 group, and 31.2% and 15.8% in the N2 group. None of the patients in the N3 group survived beyond 2 years. The overall survival rates at 5 years were 42.8% and 17.5% in the N- and N+ groups, respectively. In patients with locally advanced tumors (T4), clinical nodal status and histological nodal invasion were key prognostic factors. The presence of occult metastases in the N0 group justifies routine neck dissection.

    Joseph is a 24-months old boy referred by his pediatrician because of an "obsession" with pulling and eating hair. When Joseph was 14 months old, he enjoyed touching and twirling his mother's long hair. She observed that it seemed to provide comfort to him. At 18 months, he initiated pulling out and eating his own hair, twirling his mother's hair around his thumb and then sucking on it. Currently, he searches the carpet or a hard floor and looks for hair to eat. The identical behavior is observed at daycare. Joseph's teacher commented, "He pulled hair from a girl who has the longest hair of all the children. We try to distract him from this habit, but he is not distracted for long." Less frequently, Joseph has also eaten sand, chalk, and crayons at daycare. Joseph's mother describes him as a "happy and outgoing" child who interacts with his peers and has a best friend at the daycare. There have not been recent changes or stressful events in his life. Joseph separates from his mother with ease and he sleeps comfortably through the night in his own bed. There have been no episodes of nausea, vomiting, abdominal pain, or constipation. Strands of hair are occasionally seen in the stool. Prenatal and perinatal history was unremarkable. Joseph was breast-fed for 11 months, described as an "easy" baby, achieved motor, social, and language developmental milestones at the usual time, and has been in excellent health. He lives with his mother and maternal grandparents; the biological father has never been involved in his care. At 20 months, Joseph's pediatrician suggested cutting his hair. After several haircuts, Joseph stopped pulling his own hair. However, he continued to search the floor for hair. Hemoglobin and a blood lead level were normal. Joseph appeared pleasant and friendly with normal growth parameters and facial features. He was sitting comfortably on his mother's lap, sucking on his thumb. Social interactions with his mother were appropriate and reciprocal. He

    Objective: To investigate the effects between fish, seafood and pickled food intakes on oral squamous cell carcinoma (OSCC). Methods: A case-control study was carried out in Fujian area during September 2010 to December 2016, in which 604 newly diagnosed primary OSCC cases confirmed by pathological diagnosis were collected from hospital and 1 343 control subjects were enrolled from community and healthy hospital population. Demographic data, history of smoking drinking and tea drinking, oral hygiene status and dietary behaviors (fish, seafood and pickled food intakes) were collected by in-person interviews using a standard questionnaire.Using unconditional logistic regression to estimate adjusted odds ratios ( ORs ) and corresponding 95% confidence intervals ( CIs ) to assess the effects of fish, seafood and pickled food intakes on OSCC. Analysis stratified by smoking, alcohol drinking and bad prosthesis to explore the possible difference in association between subgroups. Multiplicative interactions and additive interactions between fish and bad prosthesis, seafood and alcohol drinking, pickled food and bad prosthesis were assessed by unconditional logistic regression, relative excess risk due to interaction ( RERI ), attributable proportion due to interaction ( AP ) and synergy index (S). Results: The average age of case group and control group were separately (58.69±13.92) years old and (59.27±11.37) years old (χ(2)=4.75, P= 0.191). The people whose fish and seafood intakes ≥3 times/week had the lower risk of OSCC, the adjusted OR (95 %CI ) values were 0.63 (0.52-0.77) and 0.51 (0.41-0.64); The stratified analysis indicated that the people having bad prosthesis had the lower risk of OSCC if they eating fish ≥3 times/week, and the adjusted OR (95 %CI ) values was 0.53 (0.39-0.71); the people having bad prosthesis had the higher risk of OSCC if they eating pickled food ≥3 times/week, the adjusted OR (95 %CI ) values was 1.37 (1.02-1.88).

    Full Text Available Mouse models show that experimental stress mimicking prolonged life-stress exposure enhances neurogenic inflammation, induces adaptive immunity cytokine-imbalance characterized by a shift to Type 1 T-helper cell cytokines and increases apoptosis of epithelial cells. This affects hair growth in otherwise healthy animals. In this study, we investigate whether a prolonged naturalistic life-stress exposure affects cytokine balance and hair parameters in healthy humans. 33 (18 exam, 15 comparison female medical students with comparable sociobiological status were analyzed during a stressful final examination period, at three points in time (T 12 weeks apart. T1 was before start of the learning period, T2 between the three-day written exam and an oral examination, and T3 after a 12 week rest and recovery from the stress of the examination period. Assessments included: self-reported distress and coping strategies (Perceived Stress Questionnaire [PSQ], Trier Inventory for the Assessment of Chronic Stress [TICS], COPE, cytokines in supernatants of stimulated peripheral blood mononucleocytes (PBMCs, and trichogram (hair cycle and pigmentation analysis. Comparison between students participating in the final medical exam at T2 and non-exam students, revealed significantly higher stress perception in exam students. Time-wise comparison revealed that stress level, TH1/TH2 cytokine balance and hair parameters changed significantly from T1 to T2 in the exam group, but not the control. However, no group differences were found for cytokine balance or hair parameters at T2. The study concludes that in humans, naturalistic stress, as perceived during participation in a major medical exam, has the potential to shift the immune response to TH1 and transiently hamper hair growth, but these changes stay within a physiological range. Findings are instructive for patients suffering from hair loss in times of high stress. Replication in larger and more diverse sample

    To analyze clinical and prognostic variables of Oral Squamous Cell Carcinoma (OSCC) cases from the indigenous population of Karachi and to correlate with the common risk factor of tobacco habit. The study was conducted at Ziauddin University, Karachi. One hundred fifty OSCC cases were collected from the Oncology Department of Ziauddin University Hospital, North Nazimabad, Karachi and Otolaryngology ward of Civil Hospital, Karachi, during 2011 and 2015. The reporting included demographic details and variables like intra-oral subsites, clinical stage and histological grade. Recurrence of tumor after initial resection was also documented. The patient's population comprised of 98 males and 52 females. The mean age was 47.1± 12.22 (range:20-78 years). Maximum numbers were seen in the 41-50 years age group. Urdu-speaking community was the most affected ethnic group (n=75). Clinico-pathological analysis revealed that majority of cases were moderately differentiated (59%) and were either clinical stage II (35%) or IV (29%) tumors. The most common intra-oral subsite came out to be buccal mucosa of cheeks (56%) followed by lateral borders of tongue (21%), lips (13%), alveolar (6%), palate (2.6%) floor of mouth (1.3%), etc. Recurrence was observed in 08 out of 150 cases. All patients underwent primary resection±neck dissection and reconstruction where possible. Overall experience with oral squamous cell carcinoma shows that it has a high tendency for local invasion as well as dissemination to regional lymph nodes, i.e. cervical lymph nodes, both are associated with a poor prognosis. Preventable risk factor of tobacco chewing has been observed in majority of these cases.

    A history of periodontal disease and the presence of circulating antibodies to selected oral pathogens have been associated with increased risk of pancreatic cancer; however, direct relationships of oral microbes with pancreatic cancer have not been evaluated in prospective studies. We examine the relationship of oral microbiota with subsequent risk of pancreatic cancer in a large nested case-control study. We selected 361 incident adenocarcinoma of pancreas and 371 matched controls from two prospective cohort studies, the American Cancer Society Cancer Prevention Study II and the National Cancer Institute Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. From pre-diagnostic oral wash samples, we characterised the composition of the oral microbiota using bacterial 16S ribosomal RNA (16S rRNA) gene sequencing. The associations between oral microbiota and risk of pancreatic cancer, controlling for the random effect of cohorts and other covariates, were examined using traditional and L1-penalised least absolute shrinkage and selection operator logistic regression. Carriage of oral pathogens, Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans , were associated with higher risk of pancreatic cancer (adjusted OR for presence vs absence=1.60 and 95% CI 1.15 to 2.22; OR=2.20 and 95% CI 1.16 to 4.18, respectively). Phylum Fusobacteria and its genus Leptotrichia were associated with decreased pancreatic cancer risk (OR per per cent increase of relative abundance=0.94 and 95% CI 0.89 to 0.99; OR=0.87 and 95% CI 0.79 to 0.95, respectively). Risks related to these phylotypes remained after exclusion of cases that developed within 2 years of sample collection, reducing the likelihood of reverse causation in this prospective study. This study provides supportive evidence that oral microbiota may play a role in the aetiology of pancreatic cancer. Published by the BMJ Publishing Group Limited.

    The psychological factors and their association with chronic inflammatory disease, aren't well recognized, yet their importance in oral lichen planus is still debated. The aim of this study was to investigate the prevalence of sleep disturbances, anxiety, depression and their association in patient with oral lichen planus. 50 patients with oral lichen planus vs. equal number of age and sex-matched healthy controls were enrolled. Questionnaires examining insomnia symptoms, excessive daytime sleepiness (Pittsburgh sleep quality index and Epworth aleepiness scale) depression and anxiety (The Hamilton rating scale for Depression and Anxiety) were used. The patients with oral lichen planus had statistically higher scores in all items of the Pittsburgh sleep quality index, the Hamilton rating scale for depression and anxiety and Epworth sleepiness scale than the healthy controls. The median and inter-quartile range of the Pittsburgh sleep quality index was 5-2 and for the oral lichen planus patients and 4-2 for the healthy controls (P Oral lichen planus patients report a greater degree of sleep problems, depressed mood and anxiety as compared with controls. We suggest to screen sleep disturbances in patients with oral lichen planus because they could be considered a prodromal symptoms of mood disorders. © 2014 European Academy of Dermatology and Venereology.

    Full Text Available Aim: The numerous changes occurring during pregnancy affect every body system, resulting in localized physical alterations in almost all parts of the body, including the oral cavity. The aim of the present study was to find the incidence of oral conditions seen particularly in the pregnant women than in the nonpregnant women. Materials and Methods: The oral health condition of 120 pregnant women referred to the outpatient department of Jodhpur Dental College General Hospital from a gynecology clinic were examined and compared with 120 nonpregnant women. The pregnant women were divided in a 3 groups of 40 each, according to the stage of pregnancy. The common oral conditions seen during pregnancy were assessed. Results: Pregnant women had a higher incidence of gingivitis and pyogenic granuloma. Gingivitis and erosion of teeth due to vomiting was seen commonly in the 3 rd trimester. The results indicated that pregnancy had an effect on the oral condition, which was mainly due to the hormonal changes seen during this period rather than other factors. Conclusion: Women planning a pregnancy or those already pregnant should be informed about the role of oral health during pregnancy and the possible outcomes of these conditions for the welfare of their foetus. They should be referred to the dental clinician for necessary counselling for preventive oral self-care and treatment, if required.

    Hereditary sensory and autonomic neuropathies (HSAN) are rare genetic syndromes of unknown etiology. They are seen in early childhood and are categorized into six different types by their symptoms. HSAN type 4 demonstrates autosomal recessive transmission pattern, with such major characteristics as loss of sense of pain, self-mutilation, anhydrosis and mental retardation. Sympathetic innervations are deficient despite the existence of sweat glands. Sufferers are hypotonic without any tendon reflexes, and neuro-motor development is retarded. In some cases tactile sensation and vibration may be intact. Biting injuries due to lack of pain sensation cause laceration, ulceration and scarring of the tongue, lips and other parts of oral mucosa. Tooth luxation and severe dental attrition have been observed. This case report presents oral and dental findings, surgical treatments and prosthetic rehabilitation of an 11- year-old boy with HSAN type 4.

    In a combined study of the Free University, Amsterdam and the Semmelweis Medical University, Budapest, the presence of epithelial dysplasia was studied in 100 cases of oral lichen planus. The criteria of epithelial dysplasia which were used in this study correspond with those reported by the WHO Collaborating Centre for Oral Precancerous Lesions in 1978. In approximately 25% of all cases, moderate or at least mild dysplasia was observed. The number of dysplastic changes per section did not show any significant correlation with the clinical type, nor with age or sex. There were no marked differences between the Amsterdam and Budapest material. Long-term data on the follow-up were not available yet. No comment can therefore be given about the meaning of the finding of epithelial dysplasia in lichen planus being a sign of premalignancy or not.

    For the purpose of studying the secretion of exogenous toxic metals into hair, the relation between their concenrations in hair and in organs, and the metal shift Hg or Mn was orally administered to Guinea pigs for protracted periods. The distributions of metals in hair and organs were examined by means of neutron activation analysis. It was found that the administration of Hg at high dose resulted in abnormally high Hg levels in hair from the 2nd dosing week and in organs after 25 weeks of dosing, and in a reduced motor activity after 25 weeks of administration. There occurred metal shifts in hair as well. Administration of Mn at high doses, on the other hand, showed no such biological influences, although a dose-dependent increase of Mn in hair was detected with time. (author)

    Opium poppy products are often illegally used for both recreational and medicinal purposes. In order to demonstrate the ingestion of opium poppy substances, morphine, codeine and their metabolites have been identified. However, morphine and codeine also originate from the ingestion of therapeutic drugs. Therefore, thebaine, one of the main opium alkaloids, in hair was suggested as a marker for chronic use of illegal opium poppy substances in the present study. First, thebaine was included in the analyte list of our routine analytical method for the simultaneous quantification of codeine, morphine, norcodeine, normorphine and 6-acetylmorphine (6-AM) in hair, which was fully validated previously. Then, the incorporation of thebaine and other opiates into hair and the effect of hair pigmentation were examined using lean Zucker rats with both dark grey and white hair on the same body. Thebaine was also measured in hair samples from actual cases of opium poppy substance use. Consequently, thebaine in hair was demonstrated as a marker of chronic use of illegal opium poppy substances using an animal study and actual cases. Thebaine and other opiates were successfully measured in pigmented hair from rats that ingested raw opium suspension. Moreover, thebaine identified in hair excluded possibility of ingestion of pharmaceutical opiates in actual cases. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Background: Unwanted hair is one of the most common medical problems affecting women of reproductive age inducing a lot of psychological stress and threatening their femininity and self-esteem. Old methods of removing unwanted hair include shaving, waxing, chemical depilation, and electrolysis, all of which have temporary results. However laser-assisted hair removal is the most efficient method of long-term hair removal currently available. It is desirable to develop a reduced cost photodynamic therapy (PDT system whose properties should include high efficiency and low side-effects. Method: Mice skin tissues were used in this study and divided into six groups such as controls, free methylene blue (MB incubation, liposome methylene blue (MB incubation, laser without methylene blue (MB, free methylene blue (MB for 3 and 4 hrs and laser, liposome methylene blue (MB for 3 hrs and laser. Methylene blue (MBwas applied to wax epilated areas. The areas were irradiated with CW He-Ne laser system that emits orange-red light with wavelength 632.8 nm and 10 mW at energy density of 5 J/ cm2 for 10 minutes. The UV-visible absorption spectrum was collected by Cary spectrophotometer. Results: Methylene blue (MB is selectively absorbed by actively growing hair follicles due to its cationic property. Methylene blue (MBuntreated sections showed that hair follicle and sebaceous gland are intact and there is no change due to the laser exposure. Free methylene blue (MB sections incubated for 3 hrs showed that He:Ne laser induced destruction in hair follicles, leaving an intact epidermis. Treated section with free methylene blue (MB for 4 hrs showed degeneration and necrosis in hair follicle, leaving an intact epidermis. Liposomal methylene blue (MB sections incubated for 3 hrs showed He:Ne laser induced destruction in hair follicles with intradermal leucocytic infiltration. Conclusions: Low power CW He:Ne laser and methylene blue (MB offered a successful PDT system

    Full Text Available Background: Hair loss is seen as an irreversible process. Most research concentrates on how to elongate the anagen, reduce the negative factors of obstructing hair growth and improve the hair number and size. Aim: In our experiment, we tried to prove that the cow placenta extract can promote hair growth by elongating hair shaft and increasing hair follicle number. Materials and Methods: Cow placenta extract (CPE, water and minoxidil applied separately on the back of depilated B57CL/6 mice for the case, negative and positive control respectively. We checked the proliferation of cells which are resident in hair sheath, and the expression of a few growth factors which stimulate hair growth. Results: Result shows that placenta extract more efficiently accelerates cell division and growth factor expression, by raising the insulin-like growth factor (IGF-1 mRNA and protein level to increase HF size and hair length. Conclusions: The extract is not a purified product; so, it is less effective than minoxidil, which is approved by the US FDA for the treatment of male pattern baldness. If refinement is done, the placenta extract would be a good candidate medicine for hair loss.

    Full Text Available Crohn’s disease (CD is an inflammatory disorder of the gastrointestinal tract that is likely caused by an inappropriate mucosal inflammatory response to intestinal bacteria in a genetically predisposed host. The lesions of CD can involve any region of the GI tract as well as extraintestinal sites such as the skin, joints, and eyes. The most common presenting symptoms are abdominal pain and prolonged diarrhea associated with fevers, fatigue, and malaise. Delayed growth and failure to thrive may also be observed in pediatric patients. Oral manifestations of CD are known as oral CD and may precede GI involvement, thus serving as early markers of this condition. We describe a 6-year-old male who presented with oral lesions as his initial manifestation of disease and review the current literature pertaining to oral CD.

    To determine prognostic factors for and compare outcome among dogs with oral malignant melanoma following excision with or without various systemic adjuvant therapies. Retrospective case series. 151 dogs with naturally occurring oral malignant melanomas treated by excision with or without adjuvant therapies from 2001 to 2012. Case accrual was solicited from Veterinary Society of Surgical Oncology members via an email list service. Information collected from case records included signalment, tumor staging, tumor characteristics, type of surgical excision, histologic diagnosis, adjuvant therapy, and survival time. The overall median survival time was 346 days. Results of multivariate analysis indicated that tumor size, patient age, and intralesional excision (vs marginal, wide, or radical excision) were considered poor prognostic indicators. All other demographic and clinical variables were not significantly associated with survival time after adjusting for the aforementioned 3 variables. A clear survival benefit was not evident with any systemic adjuvant therapy, including vaccination against melanoma or chemotherapy; however, the number of dogs in each treatment group was small. Ninety-eight dogs received no postoperative adjuvant therapy, and there was no difference in survival time between dogs that did (335 days) and did not (352 days) receive systemic adjuvant therapy. For dogs with oral malignant melanoma, increasing tumor size and age were negative prognostic factors. Complete excision of all macroscopic tumor burden improved survival time. Long-term survival was possible following surgery alone. Although systemic adjuvant therapy was not found to improve survival time, this could have been due to type II error.

    2013-12-01

    Assessment of cortisol concentrations in hair is one of the latest innovations for measuring long-term cortisol exposure. We performed a systematic review of correlates of cortisol in human hair to inform the design, analysis, and interpretation of future epidemiologic studies. Relevant publications were identified through electronic searches on PubMed, WorldCat, and Web of Science using keywords, "cortisol," "hair," "confounders," "chronic," "stress," and "correlates." Thirty-nine studies were included in this review. Notwithstanding scarce data and some inconsistencies, investigators have found hair cortisol concentrations to be associated with stress-related psychiatric symptoms and disorders (e.g., post-traumatic stress disorder), medical conditions indicating chronic activation of the hypothalamic-pituitary-adrenal axis (e.g., Cushing's syndrome), and other life situations associated with elevated risk of chronic stress (e.g., shiftwork). Results from some studies suggest that physical activity, adiposity, and substance abuse may be correlates of hair cortisol concentrations. In contrast to measures of short-term cortisol release (saliva, blood, and urine), cigarette smoking and use of oral contraceptives appear not to be associated with hair cortisol concentrations. Studies of pregnant women indicate increased hair cortisol concentrations across successive trimesters. The study of hair cortisol presents a unique opportunity to assess chronic alterations in cortisol concentrations in epidemiologic studies. Copyright © 2013 Elsevier Inc. All rights reserved.

    Between April and June, 2012, a reactive cholera vaccination campaign was done in Haiti with an oral inactivated bivalent whole-cell vaccine. We aimed to assess the effectiveness of the vaccine in a case-control study and to assess the likelihood of bias in that study in a bias-indicator study. Residents of Bocozel or Grand Saline who were eligible for the vaccination campaign (ie, age ≥12 months, not pregnant, and living in the region at the time of the vaccine campaign) were included. In the primary case-control study, cases had acute watery diarrhoea, sought treatment at one of three participating cholera treatment units, and had a stool sample positive for cholera by culture. For each case, four control individuals who did not seek treatment for acute watery diarrhoea were matched by location of residence, enrolment time (within 2 weeks of the case), and age (1-4 years, 5-15 years, and >15 years). Cases in the bias-indicator study were individuals with acute watery diarrhoea with a negative stool sample for cholera. Controls were selected in the same manner as in the primary case-control study. Trained staff used standard laboratory procedures to do rapid tests and stool cultures from study cases. Participants were interviewed to collect data on sociodemographic characteristics, risk factors for cholera, and self-reported vaccination. Data were analysed by conditional logistic regression, adjusting for matching factors. From Oct 24, 2012, to March 9, 2014, 114 eligible individuals presented with acute watery diarrhoea and were enrolled, 25 of whom were subsequently excluded. 47 participants were analysed as cases in the vaccine effectiveness case-control study and 42 as cases in the bias-indicator study. 33 (70%) of 47 cholera cases self-reported vaccination versus 167 (89%) of 188 controls (vaccine effectiveness 63%, 95% CI 8-85). 27 (57%) of 47 cases had certified vaccination versus 147 (78%) of 188 controls (vaccine effectiveness 58%, 13-80).

    Gorlin-Goltz syndrome (GGS) seems to be unusual in black persons. The authors present an Afro-Brazilian family case report of GGS. The main complaint of the index case was a painless swelling of the left mandible, which was diagnosed as an odontogenic keratocyst. Further classical features of the Syndrome were present in this patient. Other two family members were diagnosed as cases of GGS and one of them presented 11 clinical findings characteristic of the syndrome. From the three cases reported, two of them presented five major diagnostic criteria for the GGS, and the diagnosis was only made because of an oral complaint. This case series emphasizes the importance of carefully examining the patient and close relatives for signs of GGS, even if they belong to an ethnic group in which this diagnosis is unusual. © 2014 Special Care Dentistry Association and Wiley Periodicals, Inc.

    Macroscopic entropy of an extremal black hole is expected to be determined completely by its near horizon geometry. Thus two black holes with identical near horizon geometries should have identical macroscopic entropy, and the expected equality between macroscopic and microscopic entropies will then imply that they have identical degeneracies of microstates. An apparent counterexample is provided by the 4D-5D lift relating BMPV black hole to a four dimensional black hole. The two black holes have identical near horizon geometries but different microscopic spectrum. We suggest that this discrepancy can be accounted for by black hole hair - degrees of freedom living outside the horizon and contributing to the degeneracies. We identify these degrees of freedom for both the four and the five dimensional black holes and show that after their contributions are removed from the microscopic degeneracies of the respective systems, the result for the four and five dimensional black holes match exactly.

    Burning mouth syndrome (BMS) is a burning sensation in the mouth with no underlying dental or medical cause. To date, there is no satisfactory treatment for BMS. Herein, we present the case of a 42-year-old female presenting with hepatitis C virus infection along with BMS. Despite two interferon therapies and a sustained virologic response, the discomfort in her oral mucosa persisted. At the age of 51, the patient complained of burning sensation and tingling pain in the tongue; a thin layer of REFRECARE-H®, an oral care gel (therapeutic dentifrice), was applied on the oral membrane after each meal for 60 days. Application of REFRECARE-H® decreased the various symptoms including tingling pain, oral discomfort, breath odor, sleep disorder, depressive mood, and jitteriness. The improvement in quality of life continued for 30 days after application of the gel. These findings indicate that REFRECARE-H® may be effective in reducing the symptoms associated with BMS. Long-term follow-up studies with larger number of patients are required to elucidate the therapeutic effects of this gel.

    This case series describes patients with head and neck arteriovenous malformations who underwent oral and maxillofacial surgical procedures combined with interventional radiology techniques to minimize blood loss. Twelve patients underwent femoral cerebral angiography to visualize the extent of vascular malformation. Before the surgical procedures, surgical sites were devascularized by direct injection of hemostatic or embolic agents. Direct puncture sclerotherapy at the base of surgical sites was performed using Surgiflo or n-butylcyanoacrylate glue. Surgical procedures were carried out in routine fashion. A hemostatic packing of FloSeal, Gelfoam, and Avitene was adapted to the surgical sites. Direct puncture sclerotherapy with Surgiflo or n-butylcyanoacrylate glue resulted in minimal blood loss intraoperatively. Local application of the FloSeal, Gelfoam, and Avitene packing sustained hemostasis and produced excellent healing postoperatively. Patients with arteriovenous malformations can safely undergo routine oral and maxillofacial surgical procedures with minimal blood loss when appropriate endovascular techniques and local hemostatic measures are used by the interventional radiologist and oral and maxillofacial surgeon.

    Azimzadeh, Julien B.; Fabella, Brian A.; Hudspeth, A. J.

    2018-05-01

    Hair bundles are specialized organelles that transduce mechanical inputs into electrical outputs. To activate hair cells, physiologists have resorted to mechanical methods of hair-bundle stimulation. Here we describe a new method of hair-bundle stimulation, irradiation with ultraviolet light. A hair bundle illuminated by ultraviolet light rapidly moves towards its tall edge, a motion typically associated with excitatory stimulation. The motion disappears upon tip-link rupture and is associated with the opening of mechanotransduction channels. Hair bundles can be induced to move sinusoidally with oscillatory modulation of the stimulation power. We discuss the implications of ultraviolet stimulation as a novel hair-bundle stimulus.

    Full Text Available Objectives: The aim of this study was to assess the prevalence of oral mucosal lesions (OMLs and dental caries and to evaluate oral health practices among institutionalized orphan-children in Sana′a city, Yemen. Subjects and Methods: A sample of 202 institutionalized male-orphan-children in the main orphanage in Sana′a city, were matched to 202 non-orphan schoolchildren. Clinical examination included assessment of OMLs based on standard international diagnostic criteria and evaluation of dental status using the Decayed/decayed, Missed/missed and Filled/filled (DMFT/dmft index according to World Health Organization recommendations. Demographic data and oral hygiene practices were obtained by interviewing each subject using special questionnaire form. Results: Majority of children were in the 12-15 year age group. Nine types of lesions were reported among orphans; the most common lesions were fissured tongue (24.3%, herpes labialis (7.9% and traumatic ulcers (2.5%. The occurrence of herpes labialis was found to be significantly higher in orphans than in controls (P < 0.01. The prevalence of dental caries was insignificantly lower among the orphans (84.7% compared with the non-orphans (89.61%; P = 0.136. The mean dmft score was significantly lower in orphans than in controls (2.28 vs. 3.82; P = 0.001. Conclusions: The institutionalized children in this orphanage had a high prevalence of OMLs but low prevalence of dental caries, though they revealed poor oral hygiene practices. Effective oral health promotion strategies need to be implemented to improve the oral health and oral health practices of children living in orphanages.

    Increasing incidence of squamous cell carcinoma (SCC) of the oral cavity and oropharynx is reported in young adults. However, there is a paucity regarding etiology and risk factors. To evaluate the exposure potential carcinogenic factors among a sample aged 45 years and younger, diagnosed with SCC of the oral cavity and oropharynx. Eighty-five case samples aged 18-45 years, diagnosed with SCC of the oral cavity and oropharynx were compared with 85 controls who had never had cancer, matched for age and sex. This study was conducted by questionnaire-based interviews. Questionnaire contained items about exposure to the following risk factors: Caries prevalence, oral hygiene status, dental trauma, dental visit, stress, family history of cancer, environmental exposure to potential carcinogens, diet, body mass index (BMI), habits such as smoking, tobacco chewing, betel quid/pan, or supari. Odds ratios (ORs) of oral and pharyngeal cancer and the corresponding 95% confidence intervals were estimated using multiple logistic regression models. Poral hygiene, stress, dental trauma, low BMI, family history of cancer, exposure to environmental carcinogens, and habit of placement of quid for 11-20 years. An increased risk of oral and pharyngeal cancer was seen in cases who had poor oral hygiene, stress, dental trauma, low BMI, family history of cancer, exposure to environmental carcinogens, and habit of placement of quid.

    White piedra is a rare fungal infection of hair and is reported to be all the more rare on scalp. Trichosporon inkin is usually associated with white piedra of pubic hair. We report a case of white piedra of scalp hair caused by T. inkin. This is the first case reported from India and the fifth case reported worldwide. A 50-year-old Muslim female presented with white knots over scalp hair. Diagnosis of Trichosporon was made by examining KOH mounts of epilated hair and Lactophenol Cotton Blue preparations of the growth in culture. Automated mini-API test (for biochemical profiles) and Electronmicroscopy studies (for cell wall structures) helped in identification of the species. Mini-API test was also positive for Cryptococcus curvatus which could be due to similarity in biochemical and physiological properties of the two species. Absence of C. curvatus on culture further supports this view. Topical antifungal therapy resulted in clinical clearance within 2 months. Higher incidence of scalp white piedra is observed in Muslim females; contributing factor being the custom of using a veil, leading to higher humidity and limited sunlight exposure.

  11. Diffuse hair loss in an adult female: Approach to diagnosis and management

    Directory of Open Access Journals (Sweden)

    Shrivastava Shyam

    2009-01-01

    Full Text Available Telogen effluvium (TE is the most common cause of diffuse hair loss in adult females. TE, along with female pattern hair loss (FPHL and chronic telogen effluvium (CTE, accounts for the majority of diffuse alopecia cases. Abrupt, rapid, generalized shedding of normal club hairs, 2-3 months after a triggering event like parturition, high fever, major surgery, etc. indicates TE, while gradual diffuse hair loss with thinning of central scalp/widening of central parting line/frontotemporal recession indicates FPHL. Excessive, alarming diffuse shedding coming from a normal looking head with plenty of hairs and without an obvious cause is the hallmark of CTE, which is a distinct entity different from TE and FPHL. Apart from complete blood count and routine urine examination, levels of serum ferritin and T3, T4, and TSH should be checked in all cases of diffuse hair loss without a discernable cause, as iron deficiency and thyroid hormone disorders are the two common conditions often associated with diffuse hair loss, and most of the time, there are no apparent clinical features to suggest them. CTE is often confused with FPHL and can be reliably differentiated from it through biopsy which shows a normal histology in CTE and miniaturization with significant reduction of terminal to vellus hair ratio (T:V < 4:1 in FPHL. Repeated assurance, support, and explanation that the condition represents excessive shedding and not the actual loss of hairs, and it does not lead to baldness, are the guiding principles toward management of TE as well as CTE. TE is self limited and resolves in 3-6 months if the trigger is removed or treated, while the prognosis of CTE is less certain and may take 3-10 years for spontaneous resolution. Topical minoxidil 2% with or without antiandrogens, finestride, hair prosthesis, hair cosmetics, and hair surgery are the therapeutically available options for FPHL management.

    2011-12-01

    The WHO Commission on Social Determinants of Health issued the 2008 report 'Closing the gap within a generation - health equity through action on the social determinants of health' in response to the widening gaps, within and between countries, in income levels, opportunities, life expectancy, health status, and access to health care. Most individuals and societies, irrespective of their philosophical and ideological stance, have limits as to how much unfairness is acceptable. In 2010, WHO published another important report on 'Equity, Social Determinants and Public Health Programmes', with the aim of translating knowledge into concrete, workable actions. Poor oral health was flagged as a severe public health problem. Oral disease and illness remain global problems and widening inequities in oral health status exist among different social groupings between and within countries. The good news is that means are available for breaking poverty and reduce if not eliminate social inequalities in oral health. Whether public health actions are initiated simply depends on the political will. The Ottawa Charter for Health Promotion (1986) and subsequent charters have emphasized the importance of policy for health, healthy environments, healthy lifestyles, and the need for orientation of health services towards health promotion and disease prevention. This report advocates that oral health for all can be promoted effectively by applying this philosophy and some major public health actions are outlined. © 2011 John Wiley & Sons A/S.

    We examined the relation between consumption of different types of alcoholic beverages and the risk of oral and pharyngeal cancer, using data from a case-control study conducted in Italy and Switzerland between 1992 and 1997. This included a total of 749 cases of oral and pharyngeal cancer and 1,772 hospital controls, admitted for acute, non-neoplastic conditions, unrelated to alcohol and smoking consumption. Significant trends in risk were found with increasing total alcohol intake, with multivariate odds ratios (OR) of 2.1 for drinkers of 3-4 drinks/day, as compared to abstainers or light drinkers ( or = 12 drinks/day. Similar increased risks for subsequent levels of consumption were found for wine drinkers. After allowance for wine intake, the ORs for beer drinkers were 1.2 for 1-2 drinks/day, and 2.3 for > or = 3 drinks/day. Corresponding values for spirit drinkers were 1.0 and 1.9. Patterns of risk for wine drinkers were similar for wine only drinkers and drinkers of wine, plus beer and spirits. Our study indicates that in populations with frequent wine consumption, wine per se can strongly increase the risk of cancer of the oral cavity and pharynx, and confirms that the most prevalent alcoholic beverage in each population tends to be the one with the highest risk.

    Little is known regarding the success, failure, or complication rates of advanced implant procedures in patients after discontinuation therapy of long-term medications for the treatment of chronic myelogenous leukemia (CML). This case report presents initial results of a case involving implant placement in the mandible and maxilla as well as reduction of palatal oral pigmentation in a patient discontinuing long-term tyrosine kinase inhibitor (TKI) therapy for CML. A 57-year-old male was referred to the Department of Periodontics, University of Washington, Seattle, Washington, for an assessment of edentulous areas (tooth sites #3 and #14) and failing tooth #19. Previous medical treatment included oral administration (>10 years) of TKI for the treatment of CML. Systemic complications arising from long-term TKI therapy were treated with discontinuation of this medication. Concurrently, after multispecialty dental and medical consultation, extraction of tooth #19 with immediate implant placement and bilateral sinus augmentation with simultaneous implant placement were successfully performed during three separate surgical appointments. Additionally, marked reduction of oral palatal pigmentation was observed during the surgical and restorative phases after TKI discontinuation. Patients with a history of long-term TKIs for CML are at risk for developing complications that result in discontinuation of therapy. Long-term benefits of therapy may allow these patients to enjoy remission with an extended and improved quality of life. Patients undergoing discontinuation therapy may seek dental care. Therefore, dental providers need to understand these systemic interactions and, with multispecialty consultation, may help effectively treat these individuals.

    In a case of a driving ability assessment, hair analysis for ethyl glucuronide (EtG) was requested by the authorities. The person concerned denied alcohol consumption and did not present any clinical sign of alcoholism. However, EtG was found in concentrations of up to 910pg/mg in hair from different sampling dates suggesting an excessive drinking behavior. The person declared to use a hair lotion on a regularly base. To evaluate a possible effect of the hair lotion, prospective blood and urine controls as well as hair sampling of scalp and pubic hair were performed. The traditional clinical biomarkers of ethanol consumption, CDT and GGT, were inconspicuous in three blood samples taken. EtG was not detected in all collected urine samples. The hair lotion was transmitted to our laboratory. The ethanol concentration in this lotion was determined with 35g/L. The EtG immunoassay gave a positive result indicating EtG, which could be confirmed by GC-MS/MS-NCI. In a follow-up experiment the lotion was applied to the hair of a volunteer over a period of six weeks. After this treatment, EtG could be measured in the hair at a concentration of 72pg/mg suggesting chronic and excessive alcohol consumption. Overnight incubation of EtG free hair in the lotion yielded an EtG concentration of 140pg/mg. In the present case, the positive EtG hair findings could be interpreted as the result of an EtG containing hair care product. To our knowledge, the existence of such a product has not yet been reported, and it is exceptionally unusual to find EtG in cosmetics. Therefore, external sources for hair contamination should always be taken into account when unusual cosmetic treatment is mentioned. In those cases, it is recommended to analyze the hair product for a possible contamination with EtG. The analysis of body hair can help to reveal problems occurring from cosmetic treatment of head hair. As a consequence, the assessment of drinking behavior should be based on more than one

    Full Text Available Oral-facial-digital syndrome (OFD is a collective term describing thirteen distinctive, rare genetic disorders based on inheritance pattern and phenotypic expression. OFD is characterized by malformations of the oral cavity, the maxillofacial region and the arms and legs. Central nervous system anomalies, include intracerebral cysts, agenesis of the corpus callosum, hydrocephalus, cerebral/cerebellar atrophy, and berry aneurysms. Some degree of compromised intellectual ability and speech are present in affected individuals that correlate with the degree of central nervous system involvement. Furthermore, renal involvement in the form of polycystic kidney disease is evident in affected individuals in adulthood. In this article, we present a 37-year-old female patient that presented to the Rutgers School of Dental Medicine with oral-facial-digital syndrome, type 1.

    Full Text Available The present paper offers a comprehensive analysis of the way in which the oral history interview can organize knowledge about communism in Romania. The data are retrieved from the book Memorialul Durerii: Întuneric şi lumină (2013 compiled by author Iulia Hossu Longin from dozens of oral history interviews with survivors of communism. As the examination demonstrates, the first element commanding attention is memory. Hence, oral history shifts the focus from memory as object to memory as subject, or as a source of investigation per se. Secondly, the analysis reveals how the extensive use of lists structures knowledge about Romanian communism in an intelligible and insightful way. These lists not only provide a window on the communist experience but they also bring the individual -fighting against the regime - into the foreground.

    Full Text Available The shearing operation can provide double benefits to the cattle: they can become more heat tolerant and the tick infestation decreases. The cattle tick Rhipicephalus (Boophilus microplus causes great losses to dairy cattle, especially to the Holstein cattle because they are very susceptible to this tick. Its control is becoming each day more difficult, owing to the increasing resistance to acaricides they are acquiring. The objective of this work was to study the growing of haircoat following shearing. We made our experiment with 17 animals, 7 females and 10 males. They were shaved on the anterior third (head, neck, dewlap, scapula and arm of one side, at random. The work was performed in two steps: they were shorn for the first time on August 2nd 2012, with a size 10 blade in a clipper Oster model GoldenA5, which left the fur coat 2 mm long. Then we evaluated the hair length growing by collecting fortnightly three sample of hairs in the middle of the scapula, with  electric pliers, modified for this purpose, in both sides of the animals, sheared and non-sheared, until 30 days after this shearing. The three hair samples were put inside a little plastic bag per animal. Meanwhile, as we thought that the animals shearing had to be done closer to the skin, we decided to shear them again (in the same side shorn before, on October 2nd 2012. We changed our procedure using the same machine, but now with a blade size 30, which left the fur coat 1mm thick. After that, we collected again, fortnightly, samples of hairs on both sides during 2 months. The 10 longest hairs in the plastig bag were measured using a graph paper and the average per animal was calculated in each data and blade. A random design was applied for statistical analysis, the hair length of both sides, sheared and non sheared were compared by a two related samples tests – Wilcoxon, in a non parametric test, using the SPSSP 12.0 program, in each data within each blade.

    Direct immunofluorescence (DIF) is widely used for the diagnosis of bullous diseases and other autoimmune pathologies such as oral lichen planus. There is no evidence in the literature on how the following variants influence the detection rate of DIF: intraoral site chosen for the biopsy, perilesional locus or distant site from the clinical lesion, number of biopsies and instrument used. to determine if the following variants influenced the sensitivity (detection rate): intraoral site chosen for the biopsy, perilesional or distant site from the clinical lesion, number of biopsies and instrument used (punch or scalpel). A retrospective study was done at the Cátedra de Patología y Clínica Bucodental II at the Facultad de Odontología, Universidad de Buenos Aires; 136 clinical medical histories were revised for the period March 2000 - March 2005 corresponding to patients with clinical diagnosis of OLP and bullous diseases (vulgar pemphigus, bullous pemphigoid and cicatricial pemphigoid). DIF detection rate was 65.8% in patients with OLP, 66.7% in cicatricial pemphigoid patients, in bullous pemphigoid 55.6%, in pemphigus vulgaris 100%, and in those cases in which certain diagnosis could not be obtained, the DIF positivity rate was 45.5% (Pearson chi(2) (4)= 21.5398 Pr= 0.000). There was no statistically significant difference between the different sites of biopsy (Fisher exact test: 0.825). DIF detection rate in perilesional biopsies was 66.1% and in those distant from the site of clinical lesion was 64.7% (Pearson chi(2) v1)= 0.0073 Pr= 0.932. When the number of biopsies were incremented, DIF detection rate also incremented (Pearson chi(2) = 8.7247 Pr= 0.003). The biopsies taken with punch had a higher detection rate than those taken with scalpel (39.1% versus 71.7%) (Pearson chi(2) = 49.0522 Pr= 0.000). While not statistically significant, the tendency outlined in this study indicates there are intraoral regions in which the detection rate of the DIF technique is

    Describe the epidemiology of tourniquet syndromes and a cohort of such children admitted to the pediatric emergency department (PED), analyze the family's social situation to detect neglect behaviors, and analyze subsequent hospital admissions. From 1st January 2003 to 31st May 2009 in the PED, all patients admitted for tourniquet syndrome were included in the study. The data collected were day and time of admission, age, sex, length of stay, medical coverage, type and location of the constrictive agent, therapeutic management, progression, and complications. PED social workers in relation with child protective services (CPS) recovered information on the family's social situation. During the study period, 57 children were registered. The mean number of admissions per year was 8 (range: 2-15). The mean age was 5.5+/-4 months. The toe was the most frequent location (95%). The penis was injured in 2 cases and labia majora in 1 case. The constrictive agent was often a hair (95%). One case of abuse was detected. The analysis of family social situations showed that 53% had no or incomplete medical coverage, 67% were already followed by CPS with extreme poverty or lived in dilapidated housing. Insufficient hygiene or neglect was found in 67% of the families with incomplete or no social coverage. The analysis of 2003-2007 period for later admissions identified that 15 accidents in the home occurred in 12 children. Among these families, 58% were already known by CPS for neglect behavior. Although most tourniquet syndromes seem accidental, this entity is often associated with a lack of hygiene. Several and distant locations (e.g., toes and genitals), multiple and/or separated knots, constrictive agents inconsistent with a safe environment for the child, and penile location in an infant require meticulous investigation because of a higher incidence of child neglect.

    2005-01-01

    Barley mutants without root hairs or with short or reduced root hairs were isolated among M 2 seeds of 'Lux' barley (Hordeum vulgare L.) after acidified sodium azide mutagenesis. Root hair mutants are investigated intensively in Arabidopsis where about 40 genes are known. A few root hair mutants are known in maize, rice, barley and tomato. Many plants without root hairs grow quite well with good plant nutrition, and mutants have been used for investigations of uptake of strongly bound nutrients like phosphorus, iron, zinc and silicon. Seed of 'Lux' barley (Sejet Plant Breeding, Denmark) were soaked overnight, and then treated with 1.5-millimolarsodium azide in 0.1 molar sodium phosphate buffer, pH 3, for 2.5 hours according to the IAEA Manual on Mutation Breeding (2nd Ed.). After rinsing in tap water and air-drying, the M 2 seeds were sown in the field the same day. Spikes, 4-6 per M 1 plant, were harvested. The mutation frequency was similar to that obtained with other barley cultivars from which low-phytate mutants were isolated [5]. Seeds were germinated on black filter paper in tap water for 3 or 4 days before scoring for root hair mutants

  8. Oral bisphosphonates and risk of atrial fibrillation and flutter in women: a self-controlled case-series safety analysis.

    Anthony Grosso

    Full Text Available A recent trial unexpectedly reported that atrial fibrillation, when defined as serious, occurred more often in participants randomized to an annual infusion of the relatively new parenteral bisphosphonate, zoledronic acid, than among those given placebo, but had limited power. Two subsequent population-based case-control studies of patients receiving a more established oral bisphosphonate, alendronic acid, reported conflicting results, possibly due to uncontrolled confounding factors.We used the United Kingdom General Practice Research Database to assess the risk of atrial fibrillation and flutter in women exposed to the oral bisphosphonates, alendronic acid and risedronate sodium. The self-controlled case-series method was used to minimise the potential for confounding. The age-adjusted incidence rate ratio for atrial fibrillation or flutter in individuals during their exposure to these oral bisphosphonates (n = 2195 was 1.07 (95% CI 0.94-1.21. The age-adjusted incidence rate ratio for alendronic acid (n = 1489 and risedronate sodium (n = 649 exposed individuals were 1.09 (95% CI 0.93-1.26 and 0.99 (95% CI 0.78-1.26 respectively. In post-hoc analyses, an increased risk of incident atrial fibrillation or flutter was detected for patients during their first few months of alendronic acid therapy.We found no robust evidence of an overall long-term increased risk of atrial fibrillation or flutter associated with continued exposure to the oral bisphosphonates, alendronic acid and risedronate sodium. A possible signal for an increase in risk during the first few months of therapy with alendronic acid needs to be re-assessed in additional studies.

    Resources devoted to health care are limited, therefore setting priorities is required. It differs between countries whether decision-making concerning health care technologies focus on broad economic perspectives or whether focus is narrow on single budgets ("silo mentality"). The cost perspective as one part of the full health economic analysis is important for decision-making. With the case of oral anticoagulants in patients with nonvalvular atrial fibrillation (NVAF), the aim is to discuss the implication of the use of different cost perspectives for decision-making and priority setting. In a cost analysis, the annual average total costs of five oral anticoagulants (warfarin and non-vitamin K oral anticoagulants [NOACs; dabigatran, rivaroxaban, apixaban, and edoxaban]) used in daily clinical practice in Denmark for the prevention of stroke in NVAF patients are analyzed. This is done in pairwise comparisons between warfarin and each NOAC based on five potential cost perspectives, from a "drug cost only" perspective up to a "societal" perspective. All comparisons of warfarin and NOACs show that the cost perspective based on all relevant costs, ie, total costs perspective, is essential for the choice of therapy. Focusing on the reimbursement costs of the drugs only, warfarin is the least costly option. However, with the aim of therapy to prevent strokes and limit bleedings, including the economic impact of this, all NOACs, except rivaroxaban, result in slightly lower health care costs compared with warfarin. The same picture was found applying the societal perspective. Many broad cost-effectiveness analyses of NOACs exist. However, in countries with budget focus in decision-making this information does not apply. The present study's case of oral anticoagulants has shown that decision-making should be based on health care or societal cost perspectives for optimal use of limited resources. Otherwise, the risk is that suboptimal decisions will be likely.

    The purpose of this case report was to evaluate the efficacy of therapy using LEDs (light-emitting diodes), at a wavelength of 880 nm, in the prevention of oral mucositis in a patient with Hodgkin's disease treated with ABVD regimen. Mucositis is a dose limiting complication of cancer treatment, of high incidence, which severity can lead to alterations of treatment planning or even to suspension of cancer therapy, with serious consequences in tumor response and even survival. Lesions develop most commonly on the nonkeratinized mucosa and present symptoms that begin like mild burning and evolve to severe pain. For this reason, low power laser and, recently, LEDs have been considered for preventing and management of oral mucositis, with great results. In this study, a 34-year-old male received intraoral irradiations with an infrared LEDs array (3,6 J/cm 2 , 74 mW), for five consecutive days, starting on the day of chemotherapy. In each chemotherapy cycle, he received ABVD protocol on day 1 and day 15, and received LEDs treatment during five days on each ABVD infusion. To analyze results, the WHO (World Health Organization) scale was used for grading of mucositis and VAS (Visual Analogue Scale) for pain evaluation, on days 1, 3, 7, 10 and 13 post-chemotherapy. The results obtained showed the patient did not develop oral mucositis, during the five chemotherapy cycles and did not present any pain symptom. Therapy with LEDs was a safe and effective method for the prevention of oral mucositis in this case report. However, new studies are needed in order to prove the efficacy of this methodology with more patients, increasing their quality of life. (author)

    We report a series of 136 patients with advanced oral cancer who received preoperative concurrent chemoradiotherapy (CCRT) followed by surgery and who were studied clinically and histopathologically, and the indication of minimally invasive surgery was evaluated. The results and conclusions were as follows: The CR (complete response) of the primary tumor was 60.3% and the overall response rate was 92.7%. Histological effects were Grade IIb and above, i.e. effective, in 84.6% and Grade III, IV, i.e. pathological CR, in 73 of 82 (89.0%) in CR cases. The CCRT was also very effective histologically, and a correlation was observed between clinical effects and histological effects. The residual tumor grade (R Grade) in the resected specimen is considered to be useful as a prognostic factor. Histological effects were satisfactory in good partial response (PR) and CR cases on CCRT. In such cases, minimally invasive surgery is considered to be applicable even in advanced cases, and improvements in the postoperative quality of life (QOL) can be expected by preservation of the oral organs and functions.

  12. Oral rehabilitation with implant supported overdentures in patients with non-reconstructed segmental mandibulectomy: A report of two cases

    Directory of Open Access Journals (Sweden)

    Rok Zupančič

    2013-11-01

    Full Text Available Background: Segmental mandibulectomy is most often performed as part of resection of advanced squamous cell carcinoma, which involves the mandible by extension from intraoral tissues and is usually followed by reconstruction of the mandible. However, not all mandibular defects can be surgically reconstructed, due to local or systemic factors. Oral rehabilitation with conventional removable dentures is often insufficient. In order to provide predictable support and denture retention, especially in the non-reconstructed cases of segmental mandibulectomy, dental implants are indicated.Case report: The authors describe oral rehabilitation with implant-supported overdenture in two non-reconstructed patients with similar mandibular defect, but different etiology, as well as different denture design and different outcome in terms of success and patient satisfaction. In the first case, the defect was caused by surgical treatment of cancer, which was followed by radiotherapy and prosthodontic treatment with an implant-supported mandibular overdenture anchored with a bar. In another case, the damage was due to a suicide attempt. This was initially followed by the surgical treatment of the injury. Afterwards, the prosthodontic treatment with an implant-supported and conical–crown-anchored mandibular overdenture was performed.Conclusions: The success of the prosthodontic oral rehabilitation of patients with segmental mandibulectomy depends on many factors. The size of the defect and the condition of the remaining hard and soft tissues, which are affected by radiotherapy, are crucial. The etiology of the defect, the opposing jaw status, maxillomandibular relationships, the consistency of mandibular movement and the denture design play an important role as well.

    Malignant melanoma of the oral cavity is rare, accounting for 1 to 8% of all malignant melanomas. The overall prognosis remains poor despite the available treatments such as radical surgery, adjuvant radiotherapy, chemotherapy and immunotherapy due to failure in early detection and tendency in early metastasis. The etiology of mucosal malignant melanoma remains unkown. However, there are few cases of malignant melanoma of the oral cavity reported in the literature, which might be related to preexisting melanosis and radiation treatment. A case with malignant melanoma developed on the same site after 6 years following irradiation for squamous cell carcinoma of the oral cavity is reported in this article

    Objective: To evaluate the influence of oral hygiene on risk of oral cancer in non-smoking and non-drinking women. Methods: From September 2010 to February 2016, 242 non-smoking and non-drinking female patients with pathologically confirmed oral cancer were recruited in a hospital of Fuzhou, and another 856 non-smoking and non-drinking healthy women from health examination center in the same hospital were selected as control group. Five oral hygiene related variables including the frequency of teeth brushing, number of teeth lost, poor prosthesis, regular dental visits and recurrent dental ulceration were used to develop oral hygiene index model. Unconditional logistic regression was used to calculate odds ratios ( OR ) and 95% confidence intervals (95 %CI ). The area under the receiver operating characteristic curve (AUROC) was used to evaluate the predictability of the oral hygiene index model. Multivariate logistic regression model was used to analyze the association between oral hygiene index and the incidence of oral cancer. Results: Teeth brushing oral cancer in non-smoking and non-drinking women, the corresponding OR (95 %CI ) were 1.50 (1.08-2.09), 1.81 (1.15-2.85), 1.51 (1.03-2.23), 1.73 (1.15-2.59), 7.30 (4.00-13.30), respectively. The AUROC of the oral hygiene index model was 0.705 9, indicating a high predictability. Multivariate logistic regression showed that the oral hygiene index was associated with risk of oral cancer. The higher the score, the higher risk was observed. The corresponding OR (95 %CI ) of oral hygiene index scores (score 1, score 2, score 3, score 4-5) were 2.51 (0.84-7.53), 4.68 (1.59-13.71), 6.47 (2.18-19.25), 15.29 (5.08-45.99), respectively. Conclusion: Oral hygiene could influence the incidence of oral cancer in non-smoking and non-drinking women, and oral hygiene index has a certain significance in assessing the combined effects of oral hygiene.

    Ectodermal dysplasia is a clinically and genetically heterogeneous group of inherited disorders characterized by abnormal development of two or more of the following ectodermal-derived structures: hair, teeth, nails and sweat glands. The hair is the most frequently affected structure. Hair shaft abnormalities are of great concern to these patients, but no effective treatments are available. We describe three girls with congenital hypotrichosis (9, 5 and 6 years old) caused by ectodermal dysplasia treated with topical cetirizine solution (2 mL. once daily) and oral vitamin D supplementation (1000 IU daily). After 6 months of treatment, the density of hair on the scalp increased in all patients. The vellus hair was replaced by terminal hair. Hair regrowth was evaluated both from the clinical and trichoscopic point of view. We propose a combination of topical cetirizine and oral vitamin D as a rational treatment of choice in congenital hypotrichosis caused by ectodermal dysplasia. © 2016 European Academy of Dermatology and Venereology.

    Refeeding syndrome has been observed in patients receiving nutrition after a prolonged period of malnourishment and is characterized by multiple metabolic derangements. Besides hypophosphatemia and hypoglycemia, lipemia has been described in association with parenteral nutrition administration to the malnourished. The authors describe one anorexic patient who developed lipemia during oral refeeding, followed by a precipitous drop in hematocrit suggestive of fat overload syndrome.

    Although oral submucous fibrosis (OSMF) is thought to be multifactorial in origin, the chewing of areca nut is thought to be the main cause. Alkaloids and tannins in areca nut are responsible for fibrosis, but recent evidence has suggested that copper ions are also an important mediator, and in a

    In 2012, alarmingly high rates of oral artemisinin monotherapy availability and use were detected along Eastern Myanmar, threatening efforts to halt the spread of artemisinin resistance in the Greater Mekong Subregion (GMS), and globally. The aim of this paper is to exemplify how the use of supply side evidence generated through the ACTwatch project shaped the artemisinin monotherapy replacement malaria (AMTR) project's design and interventions to rapidly displace oral artemisinin monotherapy with subsidized, quality-assured ACT in the private sector. The AMTR project was implemented as part of the Myanmar artemisinin resistance containment (MARC) framework along Eastern Myanmar. Guided by outlet survey and supply chain evidence, the project implemented a high-level subsidy, including negotiations with a main anti-malarial distributor, with the aim of squeezing oral artemisinin monotherapy out of the market through price competition and increased availability of quality-assured artemisinin-based combinations. This was complemented with a plethora of demand-creation activities targeting anti-malarial providers and consumers. Priority outlet types responsible for the distribution of oral artemisinin monotherapy were identified by the outlet survey, and this evidence was used to target the AMTR project's supporting interventions. The widespread availability and use of oral artemisinin monotherapy in Myanmar has been a serious threat to malaria control and elimination in the country and across the region. Practical anti-malarial market evidence was rapidly generated and used to inform private sector approaches to address these threats. The program design approach outlined in this paper is illustrative of the type of evidence generation and use that will be required to ensure effective containment of artemisinin drug resistance and progress toward regional and global malaria elimination goals.

    Hair dye products now represent one of the most rapidly growing beauty and personal care industries as both men and women commonly change hair color to enhance youth and beauty and to follow fashion trends. Irrespective of economic and education status, people dye their hair to emphasize the importance given to appearance. Despite adverse reactions, many people continue dyeing mainly for cosmetic purposes. This paper provides a comprehensive review on various aspects of hair dying products, especially with respect to the hair-coloring process, classification, chemical ingredients, possible human health impacts, and regulations. Permanent hair dye, which is the most commonly used product type, is formed by an oxidative process involving arylamines to bring about concerns with long-term exposure. Hence, significant efforts have been put to understand the possible side effects of such exposure including cancer risk. However, hair dyes and their ingredients are mainly identified to have moderate to low acute toxicity such as the cause of allergic contact dermatitis. Although some hair dye components are reported to be carcinogenic in animals, such evidence is not consistent enough in the case of human studies. Consequently, further research is desirable to critically address the significance of this issue, especially with respect to the safety of hair dye ingredients. Copyright © 2016 Elsevier Ltd.

    A 10-week inpatient study was performed to evaluate cocaine, codeine, and metabolite disposition in biological matrices collected from volunteers. An initial report described drug disposition in plasma, sebum, and stratum corneum collected from five African-American males. This report focuses on drug disposition in hair and sweat collected from the same five subjects. Following a three-week washout period, three doses of cocaine HCl (75 mg/70 kg, subcutaneous) and three doses of codeine SO4 (60 mg/70 kg, oral) were administered on alternating days in week 4 (low-dose week). The same dosing sequence was repeated in week 8 with doubled doses (high-dose week). Hair was collected by shaving the entire scalp once each week. Hair from the anterior vertex was divided into two portions. One portion was washed with isopropanol and phosphate buffer; the other portion was not washed. Hair was enzymatically digested, samples were centrifuged, and the supernatant was collected. Sweat was collected periodically by placing PharmChek sweat patches on the torso. Drugs were extracted from sweat patches with methanol/0.2 M sodium acetate buffer (75:25, v/v). Supernatants from hair digests, hair washes, and sweat patch extracts were processed by solid-phase extraction followed by gas chromatography-mass spectrometry analysis for cocaine, codeine, 6-acetylmorphine, and metabolites. Cocaine and codeine were the primary analytes identified in sweat patches and hair. Drugs were detected in sweat within 8 h after dosing, and drug secretion primarily occurred within 24 h after dosing. No clear relationship was observed between dose and drug concentrations in sweat. Drug incorporation into hair appeared to be dose-dependent. Drugs were detected in hair within 1-3 days after the last drug administration; peak drug concentrations generally occurred in the following 1-2 weeks; thereafter, drug concentrations decreased. Solvent washes removed 50-55% of cocaine and codeine from hair collected 1

    2016-03-01

    Full Text Available Introduction: Tetralogy of Fallot is a congenital heart disease and the most common cyanotic heart defect in children. It is clinically characterized by a ventricular septal defect, pulmonary stenosis, overriding aorta over ventricular septal defect and right ventricular hypertrophy. There is little or no information about the oral manifestations in patients with this pathology. A report and discussion of a pediatric patient diagnosed with Tetralogy of Fallot, its clinical manifestations, oral findings and dental management are presented. Case Report: A four-year-old male patient diagnosed with Tetralogy of Fallot and epileptic attacks. The patient has deciduous teeth with many severe early childhood caries, stomatitis and cyanotic mucous membranes, root fragments, periapical abscess and noticeable enamel hypoplasia. Conclusions: In agreement with other authors, children with systemic diseases such as Tetralogy of Fallot have a higher rate of caries, poor oral hygiene, high susceptibility to other infections and bacterial endocarditis, cyanotic mucous membranes and enamel hypoplasia. Primary prevention is critical, proper dental hygiene, regular dental check-ups and the use of antibiotic prophylaxis are particularly important, especially in high-risk patients.

    This paper presents an algorithm for segmenting the hair region in uncontrolled, real life conditions images. Our method is based on a simple statistical hair shape model representing the upper hair part. We detect this region by minimizing an energy which uses active shape and active contour....... The upper hair region then allows us to learn the hair appearance parameters (color and texture) for the image considered. Finally, those parameters drive a pixel-wise segmentation technique that yields the desired (complete) hair region. We demonstrate the applicability of our method on several real images....

    Assessment of cortisol concentrations in hair is one of the latest innovations for measuring long-term cortisol exposure. We performed a systematic review of correlates of cortisol in human hair to inform the design, analysis and interpretation of future epidemiologic studies. Relevant publications were identified through electronic searches on PubMed, WorldCat, and Web of Science using keywords, “cortisol” “hair” “confounders” “chronic” “stress” and “correlates.” Thirty-nine studies were included in this review. Notwithstanding scarce data and some inconsistencies, investigators have found hair cortisol concentrations to be associated with stress-related psychiatric symptoms and disorders (e.g., PTSD), medical conditions indicating chronic activation of the hypothalamic-pituitary-adrenal axis (e.g., Cushing´s syndrome) and other life situations associated with elevated risk of chronic stress (e.g., shiftwork). Results from some studies suggest that physical activity, adiposity, and substance abuse may be correlates of hair cortisol concentrations. In contrast to measures of short-term cortisol release (saliva, blood, and urine), cigarette smoking and use of oral contraceptives appear to not be associated with hair cortisol concentrations. Studies of pregnant women indicate increased hair cortisol concentrations across successive trimesters. The study of hair cortisol presents a unique opportunity to assess chronic alterations in cortisol concentrations in epidemiologic studies. PMID:24184029

    Malignant melanoma (MM is a neoplasm of melanocytic origin that arises from a benign melanocytic lesion or de novo from melanocytes within otherwise normal mucosa or skin. It is one of most biologically unpredictable and deadly of all human neoplasms. It is third most common skin cancer, and accounts for 5% of all tumours. Although it comprises 1.3% of all cancers, MM of oral cavity accounts for only 0.2 to 8% of all reported melanomas. The mucosal melanoma tends to appear at a higher stage and is much aggressive than its cutaneous counterpart. The prognosis of oral melanoma is extremely poor, until recently less than 29% of affected patients survived for 5 years or more.

Clinical and radiographic examination of a patient with Apert syndrome,aged 21 years old, not previously submitted for orthodontic or orthognathic treatment.Dental anomalies were present in a patient. Intraoral evaluation revealed poor oral hygienewith varying degrees of periodontal involvement, an arched swelling (pseudo cleft configuration,class III malocclusion, anterior open bite, posterior crossbite, supernumerary teeth, ectopic eruption and creamy white enamel opacities, an excessively large appearingtongue and a v-shaped maxillary arch. The occurrence of typical lateral palatal swellings agrees with the literature. The high prevalence of dental anomalies and ectopic eruption may suggest a possible etiologic relationship with the syndrome.

    Idiopathic facial nerve palsy, also known as Bell palsy is rare in the neonatal age group. Other more common causes such as birth trauma; infections, especially otitis media; and congenital malformations need to be excluded. We present here a 4-week-old neonate with Bell palsy who responded rapidly to oral corticosteroids. Such an early presentation of idiopathic facial nerve palsy and use of corticosteroids in neonates is scarcely reported in the literature.

Besides medicinal treatment, neodymium: Yttrium aluminum garnet (Nd: YAG laser is also used for the management of oral leukoplakia. This study evaluated the role of Nd: YAG laser in the management of oral leukoplakia and also investigated postoperative complications along with long-term prognosis of the disease. Settings and Designs: The study is a prospective cohort study conducted for 24 months (June 2011 to May 2013 in Lucknow. Materials and Methods: The study comprised of 42 patients, both male and female of Indian origin and diagnosed with oral leukoplakic lesions. Patients with biopsy proven squamous cell carcinoma and medically compromised are excluded from the study. All patients has undergone ablation of lesion by pulsed Nd: YAG laser and were followed after 24 h, 72 h, 1-week and then successively for 1, 3, 6 months and then 1 st and 2 nd postoperative years. Results: Pain and slough were evaluated by Wicoxon rank test (P = 0.0001 statistically significant which decreased from 24 h to 1-week and became nil in subsequent follow-ups. Similarly, McNemar′s test (P = 0.001 statistically significant was used for evaluation of burning sensation, paresthesia, infection and recurrences. Recurrence was noted in 2 patients but following the second application, there were no recurrences over the period of further follow-up. None of the patient suffered from an infection, paresthesia or anesthesia. Conclusion: Hence, Nd: YAG laser was found to be effective in ablating leukoplakia. It is convenient, economical with minimum complications and morbidities.

    Hair can serve as a specimen for identifying past drug exposure. Segmental hair analysis may differentiate a single exposure from chronic use. Consequently, segmental hair analysis is useful for disclosing a single drug ingestion, as well as for determining repeated exposures in drug-facilitated crimes (DFCs). This paper presents an overview of toxicological investigations that have used hair analysis in DFC cases from 2009 to 2016 in Denmark. Hair concentrations were determined for 24 DFC-related drugs and metabolites, including benzodiazepines and other hypnotics, antihistamines, opioid analgesics, antipsychotics, barbiturates, and illicit drugs from DFC cases. Drug detection in hair in DFC cases following a single or few intakes of chlorprothixene, codeine, diphenhydramine, oxazepam, oxycodone, promethazine, and phenobarbital is reported for the first time in forensic toxicology. A literature review on concentrations in the published DFC-related hair cases and on concentrations in hair of these substances after single and multiple doses is included. These cases demonstrate the value of segmental hair analysis in DFCs and facilitate future interpretations of results. Copyright © 2018 Elsevier B.V. All rights reserved.

This lateral incision makes it easier to introduce micrografts by allowing air to be released and improves the fixation of the grafts by giving some elasticity to the orifice. The patients were previously beta blocked to prevent the beta-adrenergic action of epinefrin.

  16. Soft Hair on Black Holes

    Hawking, Stephen W.; Perry, Malcolm J.; Strominger, Andrew

    2016-06-01

    It has recently been shown that Bondi-van der Burg-Metzner-Sachs supertranslation symmetries imply an infinite number of conservation laws for all gravitational theories in asymptotically Minkowskian spacetimes. These laws require black holes to carry a large amount of soft (i.e., zero-energy) supertranslation hair. The presence of a Maxwell field similarly implies soft electric hair. This Letter gives an explicit description of soft hair in terms of soft gravitons or photons on the black hole horizon, and shows that complete information about their quantum state is stored on a holographic plate at the future boundary of the horizon. Charge conservation is used to give an infinite number of exact relations between the evaporation products of black holes which have different soft hair but are otherwise identical. It is further argued that soft hair which is spatially localized to much less than a Planck length cannot be excited in a physically realizable process, giving an effective number of soft degrees of freedom proportional to the horizon area in Planck units.

    The contents of Ca, Sr, Pb, Zn, Cu, Ni, Fe, Mn, Cr and Ti in hair of 32 cases with breast cancer and 105 cases with fibrocystic disease have been measured by XRF. Compared with 55 normal female adults, the hair levels of Sr, Zn, Cu, Mn and Ca in breast cancer patients and the hair levels of Sr, Mn and Ca in fibrocystic disease patients were significantly decreased (P<0.01 or P<0.001). However, the hair contents of Zn, Ni and Cr in fibrocystic disease patients were dramatically increased (P<0.05)

    2011-01-01

    Loss of hair-bearing regions of the face caused by trauma, tumor resection, or burn presents a difficult reconstructive task for plastic surgeons. The ideal tissue substitute should have the same characteristics as the facial area affected, consisting of thin, pliable tissue with a similar color match and hair-bearing quality. This is a retrospective study of 34 male patients who underwent reconstruction of hair-bearing facial regions performed by the senior author (J.J.P.). Local and pedicled flaps were used primarily to reconstruct defects after tumor extirpation, trauma, infections, and burns. Two patients had irradiation before reconstruction. Two patients had prior facial reconstruction with free flaps. The authors found that certain techniques of reconstructing defects in hair-bearing facial regions were more successful than others in particular facial regions and in different sizes of defects. The authors were able to develop a simple algorithm for management of facial defects involving the hair-bearing regions of the eyebrow, sideburn, beard, and mustache that may prospectively aid the planning of reconstructive strategy in these cases.

    This study presents the case of a 4-year-old healthy child admitted to the paediatric ward for suspected accidental intoxication due to ingestion of narcoleptic drugs (methylphenidate, sertraline and quetiapine), taken on a regular basis by his 8-year-old brother affected by Asperger syndrome.Intoxication can be objectively assessed by measurements of drugs and metabolites in biological matrices with short-term (blood and urine) or long-term (hair) detection windows. At the hospital, the child's blood and urine were analysed by immunoassay (confirmed by liquid chromatography-mass spectrometry), and sertraline and quetiapine and their metabolites were identified. The suspicion that the mother administered drugs chronically prompted the analysis of six, consecutive 2-cm segments of the child's hair, using ultra-high performance liquid chromatography-tandem mass spectrometry, thereby accounting for ingestion over the previous 12 months. Quetiapine was found in the first four segments with a mean concentration of 1.00 ng/mg ± 0.94 ng/mg hair while sertraline and its metabolite, desmethyl-sertraline, were found in all segments with a mean concentration of 2.65 ± 0.94 ng/mg and 1.50 ± 0.94 ng/mg hair, respectively. Hair analyses were negative for methylphenidate and its metabolite (ritalinic acid). Biological matrices testing for psychoactive drugs disclosed both acute and chronic intoxication with quetiapine and sertraline administered by the mother.

  1. A STUDY ON CONTACT DERMATITIS TO HAIR DYE AND HENNA

    Directory of Open Access Journals (Sweden)

    2013-10-01

    Full Text Available P- Phenylenediamine is an oxidative chemical that is frequently used as a permanent hair-coloring agent. It is added to henna to increase the intensity and longevity of the tattoo and expedites its drying time. Henna itself is a greenish brown vegetable coloring made from the leaves of Lawsonia inermis and rarely causes allergic contact dermatitis. The addition of PPD causes the contact sensitization to black henna. Serious adverse skin reactions to permanent hair dyes and temporary black tattoos have been reported. As temporary tattoos have become fashionable among adolescents, the risk profile for p-phenylenediamine (PPD sensitization of the population has changed simultaneously with an increasing use of hair dyes in this age group. With increased popularity of body art such as body piercing and tattooing, an increase in temporary henna tattoos has also occurred. Although the appeal of non-permanence exists for henna tattoos, dermatologists have begun to see numerous cases of allergic contact dermatitis linked with a certain type of henna. We selected 50 patients using hair dye and henna for our study. Patch testing was done in all the patients using Indian standard series of antigens. Regarding to the side effects to hair dye and henna and itching was the commonest symptom seen in 16% patients, erythematous scaly plaques were seen in 10% patients, vesicular reactions were seen in 6% patients, angioneurotic oedema and contact urticaria was seen in 4% patients each and anaphylaxis and keloidal reaction was seen in 2% patients each.

  2. Advanced analysis of metal distributions in human hair

    2006-01-01

    A variety of techniques (secondary electron microscopy with energy dispersive X-ray analysis, time-of-flight-secondary ion mass spectrometry, and synchrotron X-ray fluorescence) were utilized to distinguish metal contamination occurring in hair arising from endogenous uptake from an individual exposed to a polluted environment, in this case a lead smelter. Evidence was sought for elements less affected by contamination and potentially indicative of biogenic activity. The unique combination of surface sensitivity, spatial resolution, and detection limits used here has provided new insight regarding hair analysis. Metals such as Ca, Fe, and Pb appeared to have little representative value of endogenous uptake and were mainly due to contamination. Cu and Zn, however, demonstrate behaviors worthy of further investigation into relating hair concentrations to endogenous function.

    Hair has been used for years in the assessment and documentation of human exposure to drugs, as it presents characteristics that make it extremely valuable for this purpose, namely the fact that sample collection is performed in a noninvasive manner, under close supervision, the possibility of collecting a specimen reflecting a similar timeline in the case of claims or suspicion of a leak in the chain of custody, and the increased window of detection for the drugs. For these reasons, testing for drugs in hair provides unique and useful information in several fields of toxicology, from which the most prominent is the possibility of studying individual drug use histories by means of segmental analysis. This paper will review the unique role of hair as a complementary sample in documenting human exposure to drugs in the fields of clinical and forensic toxicology and workplace drug testing.

    Pubescence layers with their native structure and orientation were isolated from the leaves of Olea europaea L. and Olea chrysophylla L. They were almost transparent in the visible, but considerable absorptance was evident in the ultraviolet-B region (UV-B), with maximum at 310 nm. Methanolic extracts of hairs from Olea and a variety of other pubescent species consistently showed the existence of UV-screening pigments. Absorptance of trichomes varied, but a trend towards more effective UV-B radiation attenuation in the sub-alpine Verbascum species may be claimed. In all cases, pigments were located within hair cells and in Olea they were characterized as phenolics with considerable flavonoid contribution. It is suggested that leaf hairs, besides other functions, may constitute a shield against UV-B radiation. (author)

    The objective of this systematic review was to investigate the etiologies of hair loss of the eyebrow and eyelash that required hair transplantation, the optimal surgical technique, patient outcomes, and common complications. A total of 67 articles including 354 patients from 18 countries were included in this study. Most patients were women with an average age of 29 years. The most common etiology requiring hair transplantation was burns, occurring in 57.6 percent of cases. Both eyebrow and eyelash transplantation use follicular unit transplantation techniques most commonly; however, other techniques involving composite grafts and skin flaps continue to be utilized effectively with minimal complication rates. In summary, many techniques have been developed for use in eyebrow/eyelash transplantation and the selection of technique depends upon the dermatologic surgeon's preferences and the unique presentations of their patients.

    The recent detection of GRB 170817A and GW170817 constrains the speed of gravity waves cT to be that of light, which severely restricts the landscape of modified gravity theories that impact the cosmological evolution of the Universe. In this work, we investigate the presence of black hole hair in the remaining viable cosmological theories of modified gravity that respect the constraint cT=1 . We focus mainly on scalar-tensor theories of gravity, analyzing static, asymptotically flat black holes in Horndeski, Beyond Horndeski, Einstein-scalar-Gauss-Bonnet, and Chern-Simons theories. We find that in all of the cases considered here, theories that are cosmologically relevant and respect cT=1 do not allow for hair, or have negligible hair. We further comment on vector-tensor theories including Einstein-Yang-Mills, Einstein-Aether, and generalized Proca theories, as well as bimetric theories.

    As a result of capillary forces, animal hairs, carbon nanotubes or nanowires of a periodically or randomly distributed array often assemble into hierarchical structures. In this paper, the energy method is adopted to analyse the capillary adhesion of microsized hairs, which are modelled as clamped microcantilevers wetted by liquids. The critical conditions for capillary adhesion of two hairs, three hairs or two bundles of hairs are derived in terms of Young's contact angle, elastic modulus and geometric sizes of the beams. Then, the hierarchical capillary adhesion of hairs is addressed. It is found that for multiple hairs or microcantilevers, the system tends to take a hierarchical structure as a result of the minimization of the total potential energy of the system. The level number of structural hierarchy increases with the increase in the number of hairs if they are sufficiently long. Additionally, we performed experiments to verify our theoretical solutions for the adhesion of microbeams

    Full Text Available Cigarette smoke was used to simulate a polluted environment and an experiment was performed to reveal how virgin and bleached hair are damaged by a polluted environment. The dry/wet combability, surface contact angle, tryptophan content, and cuticle morphology of the smoke exposed hair were evaluated, and compared to unexposed virgin hair. The results showed that pollution exposure can cause significant chemical damage to hair. In particular, virgin hair exposure to pollution can cause damage to the hair cuticles (higher wet/dry combing, protein degradation, and a more hydrophilic hair surface. The experiment also demonstrated that the styling polymer, polyimide-1 (isobutylene/dimethyl amino propyl maleimide/ethoxylated maleimide/maleic acid copolymer, can provide effective protection against such hair damage.

    Full Text Available One hundred patients suffering from male pattern baldness were given 3 to 4 sittings of hair transplantation at an interval of about 4 to 6 weeks each. They included 46 patients of type III baldness, 23 patients of type III (vertex baldness, and 31 patients of type IV baldness. It needed 3 sittings in type III as well as type III (vertex patients, whereas type IV patients needed 4 sittings for cosmetically acceptable results. Sixty percent patients of type III (including type III vertex showed excellent results; whereas 24 percent patients showed good response. Thirty-four percent patients of type IV got excellent cosmetic appearance; whereas, good results could be obtained in 17 percent patients. The reasons for poor results in certain patients were poor density of hair at donor sites and poor growth of hair in some of the transplanted plugs.

    This case report presents short and long-term treatment results of a unilateral cleft lip and palate patient treated with a modified intra-oral tooth-bone borne distraction appliance. The chief complaints of a 16 year-old, unilateral cleft lip and palate patient were poor facial aesthetics, crowding and a fistula. Severe maxillary retrognathism was treated via distraction osteogenesis of the maxilla and performed using an intra-oral tooth-bone borne appliance. Treatment continued to completion with a multibracket system. At an eight-year review following the distraction procedure, the short and long-term results were determined cephalometrically. Following the distraction, A-point advanced 7 mm, 2 mm of which relapsed during fixed appliance treatment. At the end of the active treatment, the patient's skeletal and dental Class III relationship improved to Class I, which was preserved at the long-term review. The profile was markedly improved by the distraction osteogenesis. In cases of severe maxillary retrognathism as a result of a cleft lip and palate, maxillary distraction osteogenesis provides a viable alternative to orthognathic surgery.

    Oral cholera vaccines represent a new effective tool to fight cholera and are licensed as two-dose regimens with 2-4 weeks between doses. Evidence from previous studies suggests that a single dose of oral cholera vaccine might provide substantial direct protection against cholera. During a cholera outbreak in May, 2015, in Juba, South Sudan, the Ministry of Health, Médecins Sans Frontières, and partners engaged in the first field deployment of a single dose of oral cholera vaccine to enhance the outbreak response. We did a vaccine effectiveness study in conjunction with this large public health intervention. We did a case-cohort study, combining information on the vaccination status and disease outcomes from a random cohort recruited from throughout the city of Juba with that from all the cases detected. Eligible cases were those aged 1 year or older on the first day of the vaccination campaign who sought care for diarrhoea at all three cholera treatment centres and seven rehydration posts throughout Juba. Confirmed cases were suspected cases who tested positive to PCR for Vibrio cholerae O1. We estimated the short-term protection (direct and indirect) conferred by one dose of cholera vaccine (Shanchol, Shantha Biotechnics, Hyderabad, India). Between Aug 9, 2015, and Sept 29, 2015, we enrolled 87 individuals with suspected cholera, and an 898-person cohort from throughout Juba. Of the 87 individuals with suspected cholera, 34 were classified as cholera positive, 52 as cholera negative, and one had indeterminate results. Of the 858 cohort members who completed a follow-up visit, none developed clinical cholera during follow-up. The unadjusted single-dose vaccine effectiveness was 80·2% (95% CI 61·5-100·0) and after adjusting for potential confounders was 87·3% (70·2-100·0). One dose of Shanchol was effective in preventing medically attended cholera in this study. These results support the use of a single-dose strategy in outbreaks in similar epidemiological

    This study aims to evaluate the independent and joint effects of tea and milk consumption on oral cancer risk among non-smokers and non-drinkers (NS/ND). A hospital-based case-control study was performed in Fujian, China. 421 cases and frequency-matched 1398 controls were included without tobacco smoking and alcohol drinking habits. Unconditional logistic regression model was used to assess the relationship of tea and milk consumption with oral cancer risk. Tea and milk consumption were significantly associated with decreased risk of oral cancer, the adjusted odds ratios (aORs) were 0.73 (95% CI: 0.54-0.97) and 0.69 (95% CI: 0.55-0.88), respectively. According to subgroup analysis, the inverse associations between tea consumption and oral cancer risk were only observed among the elders (>60 years) and urban residents. While the protect effect of milk drinking was more obvious in males, normal body mass index population (18.5-23.9), urban residents and those age ≤ 60 years. Additionally, a significantly multiplicative interaction between tea and milk consumption was observed for oral cancer risk (P = 0.001). The present study is the first to simultaneously assess the association of tea consumption and milk drinking with oral cancer risk. The results suggest that tea and milk consumption are independent protective factors for oral cancer among NS/ND, with a joint effect between them.

    Full Text Available Purpose: The treatment of oral mucosal lesions and mucosal hypertrophy in particular, is most often achieved by an excision with or without covering the surface of the wound. The platelet rich fibrin membrane (PRFm is an autogenous product containing platelets and leukocytes and their secreted growth factors and cytokines. The purpose of the presented clinical case is to describe a new, recent technique used for the covering of mucosal wounds left after the removal of pathological lesions. Material and Methods: On a single patient mucosal hypertrophy was removed by an excision with scalpel and the resulting surgical wound was covered with an autogenous PRF membrane. Postoperatively the healing process was followed on the 7th, 14th and 30th day. Results: The healing period went smoothly with minimal postoperative discomfort and no complications. Conclusion: The results of the presented clinical case demonstrate that the PRF membrane can successfully be used to cover postoperative mucosal defects.

    Mucous membrane pemphigoid (MMP) refers to a group of chronic autoimmune subepithelial diseases distinguished by erosive lesions of the mucous membranes and skin. Its treatment consists of inhibition of the inflammatory reaction by means of corticosteroids and symptomatic medication. This is a report of a patient suffering from a combination of MMP and severe generalized chronic periodontitis. The patient has been treated with oral corticosteroids, initial phase therapy, extraction with immediate implant placement, and periodontal surgery where the prognosis was questionable. The case has been followed up for 15 years. Periodontal therapy with immediate implant placement was determined to be a viable modality to achieve a total rehabilitation of a case suffering from MMP combined with severe generalized chronic periodontitis.

    An 82-year-old male presented with a chief complaint of upper abdominal pain. Subsequently, a bezoar and a gastric ulcer were detected by upper gastrointestinal endoscopy. The bezoar was dark green in color and extremely hard, having a major axis of 7 cm. After hospitalization, 500-1000 ml/day of Coca-Cola was orally administered continuously for 3 weeks. Thereafter, the bezoar decreased in size to a major axis of 4 cm and showed a softening trend. Therefore, lithotripsy was thereafter carried out under endoscopy using forceps.

    The question of why different races appear more susceptible to hair contamination by external drugs remains controversial. This research studied susceptibility of head hair to external cocaine and methamphetamine when hair products have been applied. Three different chemical classes of ethnic hair products were applied to Caucasian, Asian, and African hair. Some products increased the methamphetamine and cocaine concentrations in all hair types. A unique finding of this research is that certain ethnic hair products can replace moisture as a diffusion medium, thereby increasing the susceptibility to contamination over 100-fold compared to petroleum-based products.

    In this paper, the authors present a critical review of different studies regarding hair testing of endogenous γ-hydroxybutyrate (GHB), concentrations in chronic users, and values measured after a single GHB exposure in drug facilitated sexual assault (DFSA) cases together with the role of a recently identified GHB metabolite, GHB-glucuronide. The following databases (up to March 2017) PubMed, Scopus and Web of Science were used, searching the following key words: γ-hydroxybutyrate, GHB, GHB glucuronide, hair. The main key words "GHB" and "γ-hydroxybutyrate" were searched singularly and then associated individually to each of the other keywords. Of the 2304 sources found, only 20 were considered appropriate for the purpose of this paper. Summing up all the studies investigating endogenous GHB concentration in hair, a very broad concentration range from 0 to 12 ng/mg was found. In order to detect a single GHB dose in hair it is necessary to commonly wait 1 month for collecting hair and a segmental analysis of 3 or 5 mm fragments and the calculation of a ratio between the targeted segment and the others represent a reliable method to detect a single GHB intake considering that the ratios presently proposed vary from 3 and 10. The only two studies so far performed, investigating GHB-Glucuronide in hair, show that the latter does not seem to provide any diagnostic information regarding GHB exposure. A practical operative protocol is proposed to be applied in all suspected cases of GHB-facilitated sexual assault (GHB-FSA).
