Gallbladder metastasis is an extremely rare entity [1]. It is mainly secondary to melanoma but has also been reported as originating from breast cancer, renal cell carcinoma, and gastric cancer. Its diagnosis is often late in the advanced stage of the disease with the involvement of other organ systems [2].

We present a case of a patient who developed gastric cancer gallbladder metastasis. These findings are usually incidental on pathology of cholecystectomy specimens [1]. In our case, the metastatic lesion was demonstrated on magnetic resonance imaging (MRI) prior to surgery. Of note, the lesion had a similar enhancement pattern to the primary tumor.

Background: Reports of burn injuries in children are usually made by highly specialized burn units. Our facility admits children with burns < 20% total body surface area, while those with major burns are transferred to burn units at tertiary care facilities.

Objectives: To review our experience with thermal burns.

Methods: We conducted a retrospective review of all thermal burns admitted to our hospital during a 5 year period.

Results: Among 266 patients (69.2% boys) aged 3.5 ± 3.6 years, children < 3 years old were the most frequently injured (64.7%). Scalds (71.4%) were the most common type of burn. Partial thickness burns were sustained by 96.6% of children and TBSA[1] burned was 4.2 ± 3.6%. The mean hospital stay was 3.8 ± 4.5 days, and was significantly prolonged in girls (4.6 ± 4.8 vs. 3.5 ± 4.3 days, P = 0.01). Percent TBSA burned was correlated with patient age (r = 0.12, P = 0.04) and length of hospital stay (r = 0.6, P < 0.0001). Six patients (2.3%) (mean age 3.4 ± 2.3 years) were hospitalized in the Pediatric Intensive Care Unit due to toxin-mediated illness.

Conclusions: Children under the age of 3 years are at increased risk for burn injury, but older children sustain more extensive injuries. Prevention and awareness are needed for child safety.

Background: Early detection of malignant melanoma of the skin is the most important factor in patient survival. Naked-eye diagnostic sensitivity and specificity are low. Patients with multiple nevi are at high risk to develop melanomas and the clinical follow-up of such patients is difficult, resulting in missed melanomas on the one hand and unnecessary biopsies on the other.

Objectives: To describe the set-up of a special clinic aimed at early detection of melanoma and follow-up of high risk patients and preliminary results from 20 months of operation.

Methods: We established a pigmented lesions clinic based on a digital photography studio enabling documentation and comparison over time of full body photography and dermoscopy.

Results: In the first 20 months of work, 895 patients were seen, 206 of them for follow-up visits. A total of 29,254 photos were taken. Altogether, 236 lesions were suspicious (either clinically or dermoscopically) and the patients were advised to excise them. Seven melanomas were found in this initial examination (which did not include long-term follow-up).

Conclusions: With multimode photographic cutaneous surveillance, early detection of melanoma in high risk patients has been reported. Our clinic utilizes the same techniques and diagnostic algorithm as other leading clinics throughout the world, thus enabling us to deliver better follow-up for those patients.
 

Background: Burns are a major public health problem, with long hospitalization stay in both intensive care units and general wards. In Israel about 5% of all hospitalized injuries are burn injuries. There are no long-term epidemiological studies on burn injuries in adults in Israel.

Objectives: To identify risk factors for burn injuries and provide a starting point for the establishment of an effective prevention plan.

Methods: We analyzed the demographic, etiologic and clinical data of 5000 burn patients admitted to the five major hospitals with burn units in Israel during a 7 year period (1997–2003). Data were obtained from the records of the Israeli National Trauma Registry. The differences between various groups were evaluated using the chi-square test.

Results: Male gender was twice as frequent as female gender in burn patients (68.0% vs. 31.9%), and Jewish ethnicity was more common than non-Jewish (62.3% vs. 36.8%). Second and third-degree burns with body surface areas less than 10% constituted the largest group (around 50%). The largest age group was 0–1 years, constituting 22.2% of the cases. Inhalation injury was uncommon (1.9%). The most common etiologies were hot liquids (45.8%) and open fire (27.5%). Children less than 10 years old were burnt mainly by hot liquids while the main cause of burns for adults > 20 years old was an open flame. The majority of burns occurred at home (58%); around 15% were work related. The mean duration of hospitalization was 13.7 days (SD 17.7); 15.5% were in an intensive care unit with a mean duration of 12.1 days (SD 17.1). Surgical procedures became more common during the period of the study (from 13.4% in 1998 to 26.59% in 2002, average 19.8%). The mortality rate was 4.4%. We found a strong correlation between burn degree and total body surface area and mortality (0.25% mortality for 2nd to 3rd-degree burns with less than 10% TBSA[1], 5.4% for 2nd to 3rd-degree burns with 20–39% TBSA, and 96.6% for burns > 90% TBSA). The worst prognosis was for those over the age of 70 (mortality rate 35.3%) and the best prognosis was for the 0–1 year group (survival rate 99.6%).

Conclusions: The groups at highest risk were children 0–1 years old, males and non-Jews (the incidence rate among non-Jews was 1.5 times higher than their share in the general population). Those with the highest mortality rate were victims of burns > 90% TBSA and patients older than 70. Most burns occurred at home.

Melanoma is the leading cause of death from skin tumors worldwide, with an annual increase in incidence over the past decade. The molecular mechanisms involved in melanoma pathogenesis are beginning to be unraveled. While a family history of melanoma and exposure to ultraviolet irradiation have been known for years as risk factors in melanoma development, the precise genes involved in inherited predisposition were defined only in the past decade. Germline mutations in two genes that play a pivotal role in controlling cell cycle and division – CDKN2A and cyclin-dependent kinase 4 (CDK4) – have been detected in autosomal, dominant, high penetrance familial melanoma cases. In addition to these two highly penetrant genes, germline mutations and polymorphisms in a few low penetrance genes have been reported in familial melanoma cases: melanocortin-1 receptor, epidermal growth factor, glutathione s-transferase M1, cytochrome p450 debrisoquine hydroxylase locus (CYP2D6) and vitamin D receptor.
