Massive subgaleal hematoma in a 62-year-old man treated with apixaban as a consequence of mild head trauma

Subgaleal hematoma, accumulation of blood in the loose areolar tissue of the subgaleal space of the skull, is considered the most catastrophic complication of instrumental delivery. It is a rare finding in older ages, usually associated with coagulation disorders, severe head trauma leading to skull base fractures and accidental or abusive hair pulling. Complications include periorbital necrotising fasciitis, permanent blindness, infections and, in extreme rare cases, airway obstruction. Most cases of subgaleal hematoma resolve spontaneously, without the need of aspiration or drainage. We present here the case of a 62-year-old male on anticoagulant therapy with apixaban for chronic atrial fibrillation, who came to the emergency department after a car accident suffering from mild head trauma. The patient was complaining of a diffuse headache and physical examination showed a large ecchymosis and edema on the frontal area of the head. His neurological examination was unremarkable. Full-body computed tomography (CT) revealed a fracture of the third right rib. Twelve hours after admission, due to an excessive decrease of hematocrit, a second CT was performed. Although the images didn’t show intracranial hemorrhage or skull base fractures, a large and diffuse hematoma of the subaponeurotic space was observed and the diagnosis of subgaleal hematoma was confirmed. Massive subgaleal hematoma after mild head trauma is rather infrequent. Early diagnosis improves outcomes and can avert serious complications. Therapeutic strategy should be based on the severity of each case. In our case, conservative treatment appeared to be a valid alternative to surgery, as hematoma resolved spontaneously within 10 days. It is noteworthy that the use of anticoagulation is the only evident factor that could have been the precipitating factor for the development of the hematoma in our patient.

Trichotillomania Masked by Diffuse Alopecia Areata: A Case Report

An 11-year-old girl previously treated for tinea capitis presented a 3-month history of continuous decrease in hair density on the vertex, frontal, and parieto-temporal areas of the scalp. Hair pull test was negative. Trichoscopic findings showed black dots, micro-exclamation point hairs, regrowing vellus hair, and zigzag hairs. Histopathology showed CD3+ peribulbar lymphocytic infiltrates and occasional eosinophils around the anagen hair follicle consistent with a non-scarring alopecia. A diagnosis of diffuse alopecia areata was made. Patient was given methylprednisolone (0.5 mg/kg/day) for 2 weeks and noted marked increase in hair density except on focal areas of the scalp. Patient eventually admitted to occasional hair pulling. Trichoscopy revealed trichoptilosis, V-sign, tulip hairs, and multiple broken hairs of varying length while a second biopsy showed trichomalacia and pigment casts consistent with trichotillomania. In this case, where co-existence of alopecia areata and trichotillomania is considered to be uncommon, trichoscopy proved to be an important tool in differentiating hair disorders with similar presentation. Knowing key features of hair diseases can help elucidate the diagnosis when presented with an atypical case.

Hair-Pulling Does Not Necessarily Serve an Emotion Regulation Function in Adults With Trichotillomania

Background: Trichotillomania (TTM) has been associated with childhood trauma and perceived stress. While it has been hypothesized that hair-pulling regulate negative emotions, the relationship between childhood trauma, perceived stress, emotion regulation, and hair-pulling has not been well-studied.Methods: Fifty-six adults with TTM and 31 healthy controls completed the Childhood Trauma Questionnaire (CTQ), Perceived Stress Scale (PSS), and Difficulties in Emotion Regulation Scale (DERS). Hair-pulling severity was measured with the Massachusetts General Hospital-Hair Pulling Scale. CTQ, PSS, and DERS total scores were compared across groups using ANCOVA and the correlation between hair-pulling severity and emotion dysregulation was determined. Regression analyses were used to estimate the association of CTQ and PSS totals with DERS, and to determine whether associations between predictors and dependent variable (DERS) differed across groups.Results: TTM patients reported higher rates of childhood trauma (p <= 0.01), perceived stress (p = 0.03), and emotion dysregulation (p <= 0.01). There was no association between emotion dysregulation and pulling severity (r = −0.02, p = 0.89). Perceived stress was associated with emotion dysregulation in both groups (p < 0.01), and no association between childhood trauma and emotion dysregulation in either group. Perceived stress was the only significant predictor of emotion dysregulation in both groups (F = 28.29, p < 0.01).Conclusion: The association between perceived stress and emotion dysregulation is not specific to TTM, and there is no association between emotion dysregulation and hair-pulling severity, suggesting that key factors other than emotion dysregulation contribute to hair-pulling. Alternative explanatory models are needed.

A case of trichotillomania with bulimia: combined with N-acetylcysteine synergistic therapy

Background Trichotillomania is a common type of obsessive-related disorder characterized by repetitive hair pulling, driven by escalating tension before the action and during the attempts to resist it, and causing variable hair loss. Most clinical treatments for trichotillomania have poor curative effects. Case presentationWe treated a case of trichotillomania with bulimia with N-acetylcysteine synergistic treatment. The pathological hair plucking behaviour and binge eating symptoms were both significantly improved.ConclusionThis case suggest that N-acetylcysteine can be one choice as a synergistic or adjuvant treatment for impulse control disorder. Moreover, trichotillomania and bulimia may have a common pathophysiological mechanism.
