Achilles tendinopathy

Achilles tendon injury (tendinopathy) and pain occur in active individuals, when the tendon is subject to high or unusual load. Achilles tendinopathy can be resistant to treatment, and symptoms may persist despite both conservative and surgical intervention. The pathology of overuse tendinopathy is non-inflammatory, with a degenerative or failed healing tendon response. The diagnosis of Achilles tendinopathy requires excellent differential diagnosis and an understanding of the role of tendon imaging. Conservative treatment must include exercise, with a bias to eccentric contractions. Surgical treatment is effective after complete tendon rupture, but may not assist recovery from overuse tendinopathy. Further research into the clinical aspects of Achilles tendinopathy is required.

Factors influencing the impact of secondary exposure to trauma

The research found significant relationships between secondary exposure to client trauma and symptoms associated with secondary traumatic stress and vicarious trauma in a sample of community mental health clinicians. The research supports developmental conceptualisations of the relationships between these constructs and burnout, and identifies potential individual vulnerability and protective factors. The portfolio explores the impact of childhood maltreatment from an attachment theory perspective. Four clinical cases are presented illustrating the clinical relevance of the impact of childhood maltreatment and attachment disturbance, and the complexities associated with current attachment classification systems and differential diagnosis.

Rickettsia

Rickettsial diseases are often undiagnosed because the treating doctor doesn’t consider it as part of the differential diagnosis, especially in Australia. A travel history is often helpful. For example, scrub typhus (Orientia tsutsugamushi) is only present in northern, tropical Australia; returning sick from a southern African game park may be due to African Tick Typhus (Rickettsia africae), following tick bites.

Adolescent depressive disorders and family based interventions in the family options multicenter evaluation: study protocol for a randomized controlled trial

Background
There is increasing community and government recognition of the magnitude and impact of adolescent depression. Family based interventions have significant potential to address known risk factors for adolescent depression and could be an effective way of engaging adolescents in treatment. The evidence for family based treatments of adolescent depression is not well developed. The objective of this clinical trial is to determine whether a family based intervention can reduce rates of unipolar depressive disorders in adolescents, improve family functioning and engage adolescents who are reluctant to access mental health services.

Methods/Design
The Family Options study will determine whether a manualized family based intervention designed to target both individual and family based factors in adolescent depression (BEST MOOD) will be more effective in reducing unipolar depressive disorders than an active (standard practice) control condition consisting of a parenting group using supportive techniques (PAST). The study is a multicenter effectiveness randomized controlled trial. Both interventions are delivered in group format over eight weekly sessions, of two hours per session. We will recruit 160 adolescents (12 to 18 years old) and their families, randomized equally to each treatment condition. Participants will be assessed at baseline, eight weeks and 20 weeks. Assessment of eligibility and primary outcome will be conducted using the KID-SCID structured clinical interview via adolescent and parent self-report. Assessments of family mental health, functioning and therapeutic processes will also be conducted. Data will be analyzed using Multilevel Mixed Modeling accounting for time x treatment effects and random effects for group and family characteristics. This trial is currently recruiting. Challenges in design and implementation to-date are discussed. These include diagnosis and differential diagnosis of mental disorders in the context of adolescent development, non-compliance of adolescents with requirements of assessment, questionnaire completion and treatment attendance, breaking randomization, and measuring the complexity of change in the context of a family-based intervention.

Balloon cell melanoma: a case report with polarized and non-polarized dermatoscopy and dermatopathology

Balloon cell melanoma is a rare melanoma subtype, with only one previous case with dermatoscopy published. It is often non-pigmented, leading to diagnostic difficulty, and there is a tendency for lesions to be thick at diagnosis. We report a case of balloon cell melanoma on the forearm of a 61-year-old man with both polarized and non-polarized dermatoscopy and dermatopathology. It presented as a firm pale nodule with focal eccentric pigmentation. The clinical images evoke a differential diagnosis of dermatofibroma, dermal nevus, Spitz nevus and basal cell carcinoma as well as melanoma. This melanoma was partially pigmented due to a small, pigmented superficial spreading component on the edge of the non-pigmented balloon cell nodule, prompting further evaluation. In retrospect there was the clue to malignancy of polarizing-specific white lines (chrysalis structures) and polymorphous vessels, including a pattern of dot vessels. The reticular lines exclude basal cell carcinoma, polarizing-specific white lines are inconsistent with the diagnosis of dermal nevus and their eccentric location is inconsistent with both Spitz nevus and dermatofibroma. Excision biopsy was performed, revealing a superficial spreading melanoma with two distinct invasive components, one of atypical non-mature epithelioid cells and the other an amelanotic nodular component, comprising more than 50% of the lesion, characterized by markedly distended epithelioid melanocytes showing pseudo-xanthomatous cytoplasmic balloon cell morphology. A diagnosis of balloon cell melanoma, Breslow thickness 1.9 mm, mitotic rate 3 per square millimeter was rendered. Wide local excision was performed, as was sentinel lymph node biopsy, which was negative.

Diagnosis and management of oral leishmaniasis--case series and literature review

The worldwide prevalence of leishmaniasis is increasing because of ecologic changes and increased medical profession awareness. Furthermore, solitary cases have been recently reported in Western countries. The authors describe the epidemiology, mode of transmission, and diagnosis of leishmaniasis and present 4 oral cases treated with systemic, localized, or combined therapy. The authors suggest that clinicians should maintain a high index of suspicion for atypical, resistant, oral and perioral lesions in individuals with a history of traveling in certain geographic regions. After diagnosis, treatment should be determined jointly by experts from the fields of oral and maxillofacial surgery, oral medicine, and dermatology based on leishmaniasis species and clinical presentation.
