Twenty-two patients with cutaneous metastases of malignant melanoma were treated with intralesional injections of the methanol extraction residue of bacillus Calmette-Guerin (MER). The local reaction consisted of erythema and pustule formation followed by ulceration and tumor necrosis. Side effects included fever, chills, headache and malaise in the majority of patients; nausea, vomiting, cyanosis and hypotension occurred infrequently. Hypersensitivity reactions were not observed. Temporary abnormalities in liver function were seen in 11 of 19 patients tested. Reversible lymphopenia and thrombocytopenia developed in 7 of 17 and 7 of 18 patients, respectively. Immune function, as measured by skin tests for delayed hypersensitivity and the in vitro response of isolated lymphocytes to mitogens and microbial antigens, was not influenced by treatment with MER. Transient increases were observed in total hemolytic complement, complement components and the reduction of nitroblue-tetrazolium by neutrophils. Eight of eighteen evaluable patients showed a complete disappearance of all injected lesions. We conclude that intratumoral injection of MER is effective treatment for cutaneous metastases of malignant melanoma, with a complete response rate comparable to that observed after intralesional injection of BCG.

We retrospectively reviewed 34 consecutive patients with serologically confirmed leptospirosis admitted during years 1992-2002. Nine patients (26.5%) had respiratory symptoms on admission including cough (n = 4), shortness of breath (n = 4), cyanosis (n = 2), and hemoptysis (n = 1). Six patients had pulmonary radiographic findings including (1) diffuse, ill-defined, ground-glass density (n = 3); (2) diffuse alveolar opacities (n = 2); and (3) small nodular density (n = 1). Male/female ratio was 8/1 and mean age was 47 years. Seven patients reported their exposure source including hunting (n = 2), fishing (n = 2), fresh water swimming (n = 2), and canoeing (n = 1). All patients had fever (mean = 40.1 degrees C). Other common symptoms were headache (n = 4), vomiting (n = 3), and myalgia (n = 3). Biological abnormalities included elevated liver enzymes (n = 8), proteinuria (n = 7), lymphopenia (n = 6), hematuria (n = 5), renal failure (n = 4), anemia (n = 4), and elevated neutrophil count (n = 4). PaO(2 )was measured for 3 patients while they were breathing room air (32, 55, and 66 mmHg). Suspected diagnosis on admission included leptospirosis (n = 2), bacterial pneumonia (n = 2), intoxication, influenza, viral hepatitis, biliary tract lithiasis, and rapidly progressive glomerulonephritis (one patient each). The first serologic testing for leptospirosis was positive for 5 patients (55%). Serovar was presumptively identified for 7 patients: Australis (n = 3), Grippotyphosa (n = 2), and Icterohaemorrhagiae (n = 2). Seven patients were treated with penicillin; two patients received no antibiotics. All patients were cured. In conclusion, patients with leptospirosis may present predominantly with nonspecific pulmonary symptoms. In these patients, leptospirosis must be suspected when there is a potential exposure to rats, especially in case of high-grade fever, myalgia, hepatitis, and renal abnormalities.

Severe combined immunodeficiency (SCID) is a potentially fatal disorder characterized by defective T- and B-lymphocyte function. We describe a 34-week female twin who had developed feeding intolerance, perioral cyanosis, abdominal distension and neutropenia at 1 month of age. Despite several evaluations including an 'inconclusive' newborn screening result for SCID, the presence of profound lymphopenia was unappreciated. Eventually a diagnosis of SCID in association with adenosine deaminase deficiency was made. This case serves to emphasize the importance of newborn screening for SCID in the context of careful evaluation of clinical and laboratory findings that may be overlooked and result in a delay in the diagnosis of a potentially life-threatening condition.

A 5-month-old, intact male ferret (Mustela putorius furo) was presented with apathy, tachypnea and exercise intolerance. On initial physical examination, tachypnea and cyanosis were the two primary clinical signs detected. The complete blood count also revealed a severe polycythemia, with lymphopenia, neutrophilia and eosinophilia. Further diagnostic imaging tests were performed. The thoracic radiographs revealed cardiomegaly and a diffuse alveolar pulmonary pattern. Consequently, an echocardiography was performed and showed an interventricular septal defect, pulmonic artery occlusion, overriding of the aorta and right ventricle hypertrophy. All abnormalities were compatible with a tetralogy of Fallot (TOF). As a treatment plan, a phlebotomy was performed and the ferret was posteriorly maintained with oxygen and fluid therapy. The following day, the hematocrit decreased 11% and the respiratory distress improved. Four days later, the ferret got clinically worse and was euthanized. A necropsy was performed and confirmed the presence of an extreme TOF with a diffused interstitial pneumonia secondary to Pneumocystis carinii. To the author's knowledge, this is the first report of an extreme tetralogy of Fallot with polycythemia in a ferret.
