Nineteen cases of canine acute leukemia were diagnosed during a 4-year period. Two main categories were identified on the basis of cytologic, hematologic, and clinical features: acute lymphoid leukemia and acute myelogenous leukemia. Clinical features included history of weight loss, anorexia, shifting limb lameness, and incoordination. Physical findings were characterized by hepatomegaly, splenomegaly, mild generalized lymphadenopathy, and pallor. Ocular lesions were found in 29% of dogs with acute myelogenous leukemia. Hematologic abnormalities included anemia, thrombocytopenia, pancytopenia, leukemia, and leukoerythroblastic reactions. Results of therapy were discouraging.

Eighty-four cases of schistosomiasis mekongi among Cambodian refugees in holding centres in Thailand received praziquantel at 30 mg/kg body-weight orally twice in one day. Those treated were admitted to hospital in order to observe side effects for 24 hours. Assessment of the efficacy of praziquantel was based on cure rates. Side effects observed consisted primarily of abdominal pain, anorexia, nausea, emesis and headache. These were generally mild and transient. Physical signs revealed mild hepatomegaly and splenomegaly. The cure rate obtained one month after treatment was 97.5% and by 2 to 12 months after treatment reached 100%.

A major common-source, foodborne epidemic of typhoid fever occurred in San Antonio, Tex, in the fall of 1981, involving 80 verified cases. We summarize the clinical course of our 34 patients who had a nonspecific symptom complex that included at the initial examination fever (32 patients, 93%), headache (19 patients, 57%), diarrhea (11 patients, 33%), and anorexia (ten patients, 30%). The most common initial diagnoses were urinary tract and upper respiratory tract infections. The subsequent isolation of Salmonella typhi from blood cultures was usually unexpected. Physical findings were different from two previous series originating in the United States. Hepatomegaly was noted in only 7% (two patients), splenomegaly was noted in 13% (four patients), and rose spots were noted in 5% (two patients) of the patients. Liver function test results, however, were abnormal in 32 (95%) of the 34 patients (mean SGOT, 155 IU/mL). Typhoid fever, as seen in this outbreak, was notable for its nonspecific and mild manifestation and uniformly favorable outcome.

We assessed the value of liver biopsy in the diagnosis of fever of unknown origin (FUO) in hospital-based patients by a retrospective analysis of all cases (24 cases) seen at the University of Michigan Medical Center over a 5-year period. Based on the findings of a liver biopsy performed in the course of the evaluation of FUO, patients were divided into two groups: a diagnostic group, in which an abnormal liver biopsy was helpful in determining the cause of the FUO, and a nondiagnostic group, which included those who had either normal biopsy results or abnormal biopsy results that did not lead to a final diagnosis. Four patients (16.7%) had diagnostic liver biopsy results (histoplasmosis in three and tuberculosis in one). Physical findings, such as hepatomegaly, and laboratory data, including routine liver chemistries, were not predictive of a diagnostic liver biopsy. Therefore, despite advances in diagnostic technology since this subject was last reviewed, liver biopsy continues to be useful in the diagnosis of FUO. Furthermore, in endemic or borderline endemic areas, histoplasmosis should be considered in the differential diagnosis of FUO, and liver biopsy can be helpful to confirm this diagnosis.

One hundred four Saudi patients with brucellosis who were admitted to Abha General Hospital in the Asir region of southern Saudi Arabia were studied. All the patients had Brucella melitensis infection; 61.5% were females while 38.5% were males. Their mean age was 32 years. Most of the patients (61.5%) lived in the lowland (Tihama) and the majority were shepherds (84.6%). The most common presenting symptoms were fever (100%), sweating (96.2%), headache (76.9%), joint pains (76.9%), and backache (73.1%). Physical findings included fever (96.2%), hepatomegaly (46.2%), splenomegaly (42.3%), tenderness over the spine (30.8%), arthritis (26.9%), and lymphadenopathy (19.2%). Mild anemia, leukopenia, and relative lymphocytosis were common. A history of raw milk ingestion was an important factor in disease transmission (84.6%), followed by close animal contact (73%) and raw liver consumption (63.3%). The study shows the effectiveness of several drug combinations in the treatment of brucellosis and the low relapse rate if the treatment is prolonged for not less than six weeks.

Psittacosis, also referred to as ornithosis, is a disease primarily of birds, which may be transmitted to humans. Psittacosis is caused by Chlamydia psittaci, an obligate intracellular parasite found worldwide. Humans are infected with C. psittaci when the organism enters the blood stream, usually through inhalation of dried excrement from diseased birds or through wound contamination with infected avian secretions. C. psittaci replicates in the liver and spleen and infects the lung and other organs hematogenously.1 The clinical manifestations of human psittacosis range from a mild respiratory infection to a severe systemic illness.1,2 Symptoms are frequently described as flu-like with fever, headache, body aches, and dry or productive cough. Sore throat, chest pain, abdominal pain, vomiting, and diarrhea are variably present. Physical findings may include a pulse-temperature dissociation, localized lung crackles, hepatomegaly, splenomegaly, and a pale macular skin rash. Chest radiographs may demonstrate lesions that are atelectatic, patchy, miliary, nodular, or consolidated in one or both lungs. White cell counts, erythrocyte sedimentation rates, and liver function tests are usually normal. In severe illness, signs and symptoms of liver dysfunction, neurological impairment, and respiratory and renal failure may be present. Since 1879 when psittacosis was recognized as a disease entity, cases have been reported in North and South America, Europe, Asia, and Australia. However, reports of psittacosis in Africa have been rare. An Ethiopian group, studying community-acquired pneumonia, published what they claimed to be the first report of psittacosis in Africa in 1994.3 The report published here is believed to be the first documented case of human psittacosis in Egypt.

In its simplest and most succinct definition, heart failure can be defined as an inability of the heart to meet the metabolic demands of the body. Despite the diverse etiologies of heart failure in the pediatric population, the presentation of heart failure represents a common constellation of symptoms, signs, and physical findings. In infants, an inability to maintain growth either secondary to decreased nutritional intake or an increased catabolic state is a hallmark of heart failure. Infants exhibit increased sympathetic tone with excessive diaphoresis and increased heart rate. Physical findings in the infants with congestive heart failure (CHF) include increased work of breathing, tachypnea and hepatomegaly. In older children, in contrast, new onset heart failure may be less overtly symptomatic. Malaise, decrease in the level of daily activity, and weight loss may be present. Symptoms of abdominal pain and nausea and anorexia can be present and sometimes divert attention from the real etiology. Physical findings include rales and peripheral edema. If there is hepatomegaly, there will likely be hepatic tenderness as well. A gallop rhythm and tachycardia are commonly present. The long-term treatment of CHF in children includes digoxin, diuretics and afterload reduction with angiotensin-converting enzyme (ACE) inhibitors. Digoxin decreases sympathetic tone and improves growth in infants. Diuretics should be used to relieve symptoms but may not be necessary in all children. ACE inhibitors are increasingly valuable in maintaining cardiac function long term. New uses of medications include the addition of spironalactone (Aldactone, G. D. Searle & Co., Chicago, IL) which, in adults, has been shown to significantly decrease both the death rate from CHF and the need for hospitalization. Beta-Blockers have been used in children in limited studies and may have a role in the treatment of patients with idiopathic dilated cardiomyopathy. Surgical treatment, such as partial vectriculectomy, has shown short-term benefit and has been used sparingly in infants.

An outpatient HIV clinic was opened in March 2005 in Binh Thanh District, a poor section of Ho Chi Minh City, Vietnam. Over 1500 patients were seen in the first year. The average age of patients was 27 years. Men represented 77% of the clinic population, women, 23% and children under the age of 16 years of age, 5% of the population. The most common risk factor among men was being an injecting drug user (IDU), 76%, and among women, being married to an IDU HIV-positive man, 35%. Physical signs of disease were uncommon: lymphadenopathy in 24% and hepatomegaly and splenomegaly in 4% and 3%, respectively. Men and women were anaemic at presentation, with a mean haemoglobin of 11.9 g/dL and 11.1 g/dL, respectively. An overwhelming majority of patients had profound immunodeficiency. The mean CD4+ cell count was 164 cells/mL and the median was 69 cells/mL. No correlation was found between the World Health Organization's stage of disease and the CD4+ cell count. Thus, the former is a poor predictor of immunity in this population. Data regarding opportunistic infections diagnosed at the first visit were studied. Candidiasis of the oral pharynx, oesophagus or vagina was found in 34.5% of the patients, and pulmonary and extrapulmonary tuberculosis was found in 32% of the patients. Pneumocystis carinii pneumonia (PCP) was diagnosed in only 3% of the patients. Cotrimoxazole prophylaxis is advocated for HIV-infected Vietnamese, but the incidence of PCP is negligible and resources could be spent elsewhere. The various opportunistic infections seen in this resource-poor clinic setting is likely to be a pattern of presentation of HIV-infected Vietnamese for some time to come.

Symptoms of pulmonary hypertension (PH) are very nonspecific. Therefore, the mean time from symptom onset to diagnosis is about two years. Dyspnea is the most common symptom of PH. In particular, progressive dyspnea on exertion is most frequently observed as the initial symptom and seen among almost all patients at the time of diagnosis. Physical findings are often normal in early stages. The most common sign is an accentuated pulmonic component to the second heart sound. In more advanced cases, there are signs of right heart failure such as jugular venous distension, hepatomegaly and peripheral edema. Transthoracic Doppler echocardiography is the best screening test to detect PH. Right heart catheterization is required to confirm the diagnosis of PH. However, additional examinations are performed to rule out known causes of PH.
