Septic shock due to Candida famata (Debaryomyces hansenii) candidemia in an ICU immunocompetent trauma-patient.

Sepsis related to Candida famata (C. famata) fungemia is extremely rare in immunocompetent patients. Moreover, septic shock has not been reported due to this yeast. A previously healthy young multi-trauma male, presented septic shock from C. famata, after he had been admitted in the Intensive Care Unit (ICU) due to haemorrhagic shock. Risk factors for candidemia in ICU patients are the presence of a central venous catheter (CVC), Total Parenteral Nutrition (TPN), use of broad-spectrum antimicrobials, immunosuppression and the length of ICU stay. The presence of CVCs, prior use of antibiotics, prolonged hospitalization, disruption of skin flora and immunocompromised states have been identified as predisposing risk factors for C. famata fungemia. It is worth noting that the present case concerns a non-immunocompromised patient, but long ICU stay and brain injury may indicate a state of immunoparalysis. Identification of the yeast was performed by partial amplification and sequencing of the 26S ribosomal DNA gene [hypervariable region D1/D2; partial sequencing of the act1 gene confirmed the identity of the strain as Debaryomyces hansenii (GenBank submission ID: 1688297)] The patient quickly recovered from sepsis after initiation of amphotericin B and was discharged on the 60th day.

The diagnostic challenge of mapping elephantiasis in the Tigray region of northern Ethiopia.

BACKGROUND: In Ethiopia, lymphatic filariasis and podoconiosis are the two neglected tropical diseases planned to be mapped together within the recently launched Ethiopian neglected tropical diseases master plan (2013-2015). However, other disorders cause tropical lymphedema, and this report aims to identify clinical epidemiological aspects of limb swelling in northern Ethiopia and to provide an algorithm orienting the clinical diagnosis. METHODS: Medical records of patients with lower limb elephantiasis attending the Italian Dermatological Centre of Mekele, Tigray capital city, over a 4-year period (2005-2009) were retrospectively analyzed. Nine variables were collected from the charts comprising demographic data, job, origin, literacy, clinical, histopathologic, microscopic, and cultural findings. RESULTS: Over a total of 511 patients, lymphedema resulted from trauma (40.7%), chronic venous insufficiency (12.5%), deep mycoses (10.8%), lymphatic filariasis (9.2%), elephantiasis nostras verrucosa (7.0%), tropical ulcer (6.3%), leprosy (4.9%), recurrent infections (3.1%), podoconiosis (1.8%), tuberculosis (1.0%), malignancy (1.3%), Kaposi's sarcoma (1.0%), leishmaniasis (0.2%), and neurofibromatosis (0.2%). CONCLUSIONS: Advanced-stage elephantiasis, chronic osteomyelitis, and podoconiosis not previously reported in Tigray were observed. Further epidemiological investigation and training programs addressed to healthcare providers at the peripheral level are needed to detect elephantiasis early, prevent disabilities, and improve patients' quality of life.

Chromoblastomycosis in Kerala, India.

BACKGROUND: We are reporting 35 new cases of Chromoblastomycosis from Central Kerala. A majority of the cases from India are reported from the Sub Himalayan belt and South India. The disease scenario in India and abroad is briefly reviewed. AIMS: To study chromoblastomycosis in Central Kerala including the demographic and clinico- investigative profile. METHODS: This report is a retrospective record analysis of 35 cases of chromoblastomycosis who presented to the Dermatology Outpatient department of our tertiary center from January 2003 to July 2010 after obtaining Institutional Review Board approval. RESULTS: The disease was found to be more common among male agriculturists. The majority of cases were from the central districts of Kerala in and around the Western Ghats. The lower extremity (60%) was more affected with 40% of the subjects remembering a prior history of trauma. Sclerotic bodies were demonstrable in scrapings from black dots in 42.8%. The characteristic mixed mycotic granuloma was demonstrable in 77.1% of cases. The most common species isolated was Fonsecaea pedrosoi. CONCLUSIONS: Chromoblastomycosis is very common in Central Kerala. The disease mainly affects male agriculturists especially those employed in rubber plantations. The most common organism is F. pedrosoi.

Posttraumatic giant proliferating trichilemmal cysts on the parietal region of the scalp.

Proliferating trichilemmal (pilar) cysts, also known as pilar tumors, are most commonly found on the scalp of elderly women. Proliferating trichilemmal cysts are rare, slowly growing, lobular masses inherited autosomal dominantly and localized on scalps, and believed to arise due to a complication of a trauma and inflammation, and 5-10% of people are reported to be effected. Herein, we present the case of a 70-year-old woman with a 23-year history of multiple enlarging scalp masses. Clinically, squamous cell carcinoma was considered in the differential diagnosis, and the lesion was totally excised. Our case emphasizes the necessity for detailed clinical and pathological correlation for differential diagnosis.

Marjolin ulcer: an overlooked entity.

Marjolin ulcer is a well-defined, but uncommon malignant ulcer that occurs in chronic wounds and cutaneous scars. Jean-Nicolas Marjolin was credited with describing this phenomenon in 1828. This entity is frequently overlooked and therefore inadequately treated leading to a poor prognosis. The malignant transformation of an ulcer is most commonly associated with burn scars, but has been reported in many other types of chronic, non healing wounds such as traumatic wounds, venous stasis and chronic pressure ulcers, fistulas, lacerations and leprosy ulcers. Development of malignancy tends to be slow with an average time of approximately 25 years. Various theories concerning pathogenesis of Marjolin ulcer have been proposed. Well-differentiated squamous cell carcinoma (SCC) is the most common histological type of Marjolin ulcer. Biopsy with histopathologic interpretation remains the gold standard for the diagnosis, with radical surgical excision being the treatment of choice. A high index of suspicion should be held by any health care provider when evaluating a chronic, non healing wound. This is a case report of a Marjolin ulcer arising on the left buttock of a patient with a long-standing history of a traumatic wound.

Post-traumatic inoculation tuberculoid leprosy after injury with a glass bangle.

A lesion of tuberculoid leprosy in an Indian lady presenting at the site of injury from a broken glass bangle is reported. The diagnosis was by classical clinical features and histopathology. The importance of the skin in leprosy transmission is emphasised.

Significance of nail changes in leprosy: a clinical review of 357 cases.

Leprosy can cause many nail changes, which have been observed in up to 64% of infected patients. The manifestations of leprosy (clinical, bacteriologic, and histological) are profoundly affected by the patient's immunological status, which also determines the prognosis. Nail changes in leprosy can be caused by neuropathy and trauma, vascular impairment, infections, and miscellaneous changes. Often more than one factor will be important. Paradoxically, nail changes in tuberculoid and lepromatous patients are similar, despite wide differences in pathology. This may be because etiological factors common to both are implicated. Factors only associated with lepromatous disease are invasion of the bones of terminal phalanges by lepromatous granulomas and endarteritis occurring during type 2 lepra reactions. Otherwise, the only difference from tuberculoid leprosy is the time of onset and the symmetry of lesions. Lepromatous patients develop nail changes late in the course of disease. The presentation is usually bilaterally symmetrical. However, these changes are not specific to leprosy, and may be observed in other peripheral neuropathies.

Melioidosis in the Northern Territory of Australia.

Melioidosis is being diagnosed with increasing frequency in the northern part of the Northern Territory, but the mortality rate remains high in the acute septicaemic form of the disease largely because of associated chronic debilitating illnesses. This paper reviews epidemiological and clinical features of human melioidosis in 37 cases seen between 1960 and 1979. Infection with Pseudomonas pseudomallei is most often contracted during the wet season by persons who have regular contact with soil or ground water, probably through pre-existing skin lesions or penetrating wounds and, occasionally, through the genitourinary tract. The clinical features of melioidosis are protean, and definitive diagnosis can only be made by bacterial culture. Certain strongly indicative features, however, may justify vigorous early treatment with antibiotics (tetracycline or doxycycline in some combination with chloramphenicol, kanamycin or trimethoprim/sulphamethoxazole) which can be life-saving in fulminant septicaemic melioidosis. These indicative features are a severely prostrating fever with signs of respiratory tract infection in a patient with a chronic debilitating condition (particularly chronic alcoholism, diabetes mellitus, malnutrition or leprosy), with regular soil contact, and with chronic or recurrent skin lesions or a recent history of a penetrating wound. In subacute or chronic forms of melioidosis, which usually localize in an organ system, the diagnosis is commonly an unexpected bacteriological finding and the prognosis is generally good.

Bone changes in leprosy: a correlation of clinical and radiographic features

Characteristic bone lesions in leprosy affect the small bones of the face, hands, and feet. They are due directly to leprous infection imposed upon denervated tissues. The manifestations of leprous bone infection vary from the presence of bacilli in the bone to actual destruction. Distal absorption involves fingers and toes with the loss of digits. Combined absorption of lenght and width of bone often affects the metatarsophalangeal joints. Tarsal absorption patterns are determined by abnormal weight-bearing forces and infection.
