A 27-year old female from Nairobi was admitted to the medical wards of the Kenyatta National Hospital in May 1991. She presented with a 4-week history of productive cough, fever, weight loss, and night sweats. She acknowledged a history of contact with a patient known to have pulmonary tuberculosis. She has never received a blood transfusion. She was single and para 3 + 0. Examination revealed a sick patient, with moderate pallor, fever of 38 degrees Celsius, and who was wasted with moderate dehydration and oral thrush. There was no finger clubbing, lymphadenopathy, or
pedal edema
. Chest examination revealed bilateral basal
pneumonia
. The spleen was palpable 4 cm below the costal margin; the liver was not enlarged. The rest of the examination was normal. On admission, complete blood count showed a haemoglobin of 5.4 g/dl, total white cells were 12.5 x 10-9/L, with 82% polymorphonuclear cells and 18% lymphocytes, erythrocyte sedimentation rate (ESR) was 85 mm/hour, and platelet count was normal. The anemia was normocytic, normochromic, and no malaria parasites were seen. Urea and electrolytes and liver function tests were normal. Sputum showed no acid fast bacilli on Ziel-Neelson Stain. HIV-1 antibodies were positive by enzyme-linked immunosorbent assay (ELISA) and Western blot. Bone marrow aspirate revealed a hypercellular marrow with reversed M:E ration, dyserythropoesis, reticulum cell hyperplasia, plentiful golden yellow pigment, and clumps of Histoplasma capsulatum. Chest X-ray showed bilateral basal
pneumonia
. She was treated with antibiotics and intravenous fluids, but she remained febrile, her general condition progressively deteriorated, and she died a week after admission. Treatment for histoplasmosis had not been commenced, and no postmortem examination was carried out.

This case presented the scenario of a patient who had severe bronchospasm from an unknown etiology. Further, she had difficulty speaking and denied any past medical history, which made a diagnosis more difficult. Prehospital providers were challenged with determining the differential diagnosis for bronchospasm and hypoxemia. Was the patient experiencing an anaphylactic reaction, acute asthmatic attack or something else? The key here, once again, is conducting a thorough assessment and patient history. Remember, all that wheezes is not asthma; therefore, providers in this case had to determine if the patient was suffering something such as anaphylaxis, asthma, bronchitis,
pneumonia
or even congestive heart failure (CHF). Typically, anaphylaxis and asthma affect ventilation, not oxygenation, so until the late stages of anaphylaxis or asthma, the patient will have difficulty moving air, but will be oxygenating OK. We understand that many respiratory conditions can cause wheezing, but CHF? Yes: As left ventricular function diminishes and leads to increased pulmonary pressure, serum begins to leak out of the pulmonary vessels and into the interstitial space. As the interstitial pressure increases, it causes narrowing of the bronchioles, and air traveling through the narrowed bronchioles causes the wheezing sound. Fluid may also be leaking out of the pulmonary capillaries and occupying space in the alveolar sacs. When the interstitial pressure is high and the bronchioles continue to narrow, providers may initially hear only the wheezing and not the crackles from the smaller airways. In these conditions, oxygen is not exchanged adequately into the blood, and the patient becomes hypoxemic. Good assessment and patient history will guide the EMS provider to the cause of bronchospasm. For example, does the patient have a history of asthma? If yes, asthma is likely to be the cause. Does the patient have any rash, hives or swelling? If yes, anaphylaxis is likely the cause. Is the patient elderly, and does he/she show
pedal edema
, JVD, hypoxemia and/or distended neck veins? If yes, CHF may be the cause. [table: see text] There are questions regarding the use of bronchodilators in patients suffering CHF. If a CHF patient is wheezing (bronchospasm), then a beta-2 selective breathing treatment may be appropriate, along with nitrates and diuretics. Oxygenation is the critical problem in CHF, and hypoxemia will continue to worsen cardiac function. Remember, both bronchoconstriction and alveolar sacs filling with fluid will impair oxygenation of the RBCs and ultimately the vital organs. Focused prehospital management of CHF is aggressive in restoring oxygenation. For example, many agencies are now using oxygen, nitrates, ACE inhibitors and CPAP. By better understanding the pathophysiology of respiratory emergencies and their differential diagnosis, we will improve patient outcomes.

Capillaria philippinensis is an emerging infection in Egypt. Reports in children are scarce. We report here two sisters with C. philippinensis infection, aged 8 and 12 years. Their father was a fisherman and they had a habit of picking small pieces of uncooked fish to eat while their mother prepared their meals. They came from El-Menia governorate, which lies in the northern part of Upper Egypt. Most reported cases from Egypt come from this governorate and nearby areas. Both sisters had persistent profuse watery diarrhea of 12 months' duration. Their weights were below the 5th percentile for age. Both were hypoalbuminemic, but only the younger had
pedal edema
. Both had hypokalemia and hyponatremia. During the course of their illness they were repeatedly admitted to different hospitals and received intravenous fluids, but the correct diagnosis was not reached. Diagnosis was made by stool examination at our hospital when eggs and larvae were detected in stool samples. Although a diagnosis was promptly made, the older sister who suffered from
pneumonia
and septic shock unfortunately died a few days after admission. The younger sister was treated successfully with albendazole 200 mg twice daily. Diarrhea abated,
pedal edema
disappeared, and she started to gain weight.
