RESUMO

Secondary syphilis develops in approximately 25% of patients infected with the spirochete bacterium Treponema pallidum. It typically develops several weeks to several months after the primary infection, which is recognized by a painless chancre. Secondary syphilis is characterized by systemic symptoms, such as malaise and fever as well as a maculopapular rash involving the trunk and extremities including the palms and soles. Condyloma lata, which are raised, fleshy lesions, tend to develop at the site of the primary chancre. Diagnosis is achieved primarily through screening and confirmational serologic testing. Histologic findings seen in condyloma lata are largely non-specific. Therefore, a high index of suspicion should be maintained and immunohistochemical stains specific for T. pallidum should be utilized.

RESUMO

The rise in popularity of "bath salts" as safe alternatives to MDMA (3,4-methylenedioxymethamphetamine), methamphetamine, and other illicit substances has resulted in increased scrutiny of the contents and toxicology associated with these products. We report a case of sudden death related to the synthetic cathinone methylone (3,4-methylenedioxy-N-methylcathinonmethylone) in a previously healthy 19-year-old man. Although several fatal case reports have been published involving methylone and other synthetic cathinones, this is the first reported case of sudden cardiac death associated with methylone use. Although lack of published data prevented a comparison of blood methylone concentrations between our case and existing reports, the amount of methylone we detected postmortem (0.07 mg/dL) is below those reported in MDMA-related fatalities. Our report suggests that methylone toxicity has been greatly underestimated by users of this synthetic cathinone.

RESUMO

OBJECTIVE: To evaluate the current evidence regarding the safety and efficacy of medical management for deep neck abscesses in children. DATA SOURCES: Pubmed and Embase databases accessed 3/27/2012. REVIEW METHODS: An a priori protocol defining inclusion and exclusion criteria was developed to identify all articles addressing medical therapy of pediatric deep neck abscesses where details regarding diagnostic criteria, specifics of medical therapy and definitions of failure were presented. The search included electronic databases to identify candidate articles as well as a manual crosscheck of references. The level of evidence was assessed and data extracted by three authors independently. Data were pooled using a random effects model due to significant study heterogeneity. RESULTS: Eight articles met inclusion criteria. The overall level of evidence was grade C. There was significant heterogeneity among the studies (I(2)=98.8%; p<.001). However, each article uniformly presented cases suggesting that medical therapy may be a viable alternative to surgical drainage in some patients. The pooled success rate of medical therapy in avoiding surgical drainage in children with deep neck infections was 0.517 (95%CI: 0.335, 0.700). When patients taken immediately to surgery were excluded and patients were placed on author defined medical protocols, the success rate increased to 0.951 (95%CI: 0.851, 1.051). Subgroup analysis by duration of intravenous antibiotic trial greater than 48h demonstrated a pooled success rate of 0.740 (95%CI: 0.527, 0.953). CONCLUSION: The current literature suggests medical management may be a safe alternative to surgical drainage of deep neck abscesses in children. However, the level of evidence lacks strength and further investigation is warranted.

RESUMO

Paranasal sinus mucoceles are epithelium-lined cystic masses usually resulting from obstruction of sinus ostia. They most frequently occur in the frontal and ethmoid sinuses. While ophthalmologic symptoms are most common, patients also report rhinological or neurological complaints. The close proximity of paranasal sinus mucoceles to the orbit and skull base predisposes the patient to significant morbidity. Computed tomography displays a non-enhancing homogenous mass with expansion of bony walls. Magnetic resonance imaging reveals variable intensity of T1-weighted images and a hyperintense mass on T2-weighted images. Histopathologically mucoceles have features of respiratory mucosa with areas of reactive bone formation, hemorrhage, fibrosis, and granulation tissue. Surgical excision is the standard treatment with trends towards endoscopic techniques.

RESUMO

External auditory canal (EAC) osteomas are rare, benign bony neoplasms that occur in wide range of patients. While chronic irritation and inflammation have been suggested as causal factors in several cases, significant data is lacking to support these suspicions. Symptoms are rare and can include hearing loss, vertigo, pain and tinnitus. Diagnosis is made based on a combination of clinical history and examination, radiographic imaging, and histopathology. Osteomas of the EAC are usually found incidentally and are unilateral and solitary. Computed tomography reveals a hyperdense, pedunculated mass arising from the tympanosquamous suture and lateral of the isthmus. Histopathologically, EAC osteomas are covered with periosteum and squamous epithelium, and consist of lamalleted bone surrounding fibrovascular channels with minimal osteocysts. Osteomas have historically been compared and contrasted with exostoses of the EAC. While they share similarities, more often than not it is possible to distinguish the two bony neoplasms based on clinical history and radiographic studies. Debate remains in the medical literature as to whether basic histopathology can distinguish osteomas of the EAC from exostoses. Surgical excision is the standard treatment for EAC osteomas, however close observation is considered acceptable in asymptomatic patients.
