Biatrial aspergillosis in a patient with immunocompetency.

A 24-year-old man presented with a 24-hour history of pain and numbness in his left arm. The patient's clinical presentation of peripheral embolism was corroborated by angiography. Echocardiographic study showed masses in both right and left atria. Pathologic specimen from the embolus confirmed the diagnosis of aspergillosis.     

Simultaneous Bilateral Tibial Tuberosity Avulsions—Over 6-Year Follow-up

Abstract Simultaneous bilateral avulsions of the tibial tuberosity are rare injuries. The authors found only five reported cases in the orthopedic literature. We add a further case of bilateral avulsions of the tibial tuberosity with the longest reported follow-up.     

Acute gluteal abscess following intramuscular chloroquine injection: a clinical and experimental study

This prospective study contains clinical and experimental parts. In the clinical study, 125 patients given intramuscular chloroquine for malaria were followed for 2 months in order to detect local injection site complications. Adequate local antiseptic conditions were ensured before giving the injection. Twenty-three patients (18.4%) had minimal local reaction in the form of redness, induration and/or a lump. No pyogenic abscess was noted in contrast to a previous report. In the second part of the study, an experimental animal (Green monkey) was given either chloroquine phosphate, Ampiclox or normal saline intramuscularly. The injection site was later biopsied and histologically examined. Intramuscular chloroquine was found to cause severe inflammatory reactions and muscle necrosis, whereas other injections had very minimal local effects. It is concluded that intramuscular chloroquine causes muscle necrosis which may lead to acute pyogenic abscess if minimal contamination takes place.     

Hereditary deficiencies of antithrombin III, protein S, and the protein C pathway in Jordanian thrombosis patients.

Hereditary thrombophilia is caused by various inherited disorders. Most lead to a familial tendency to recurrent venous, not arterial, thrombosis, usually at a young age, and with spontaneous onset. Most of the genetic defects known today affect the function of natural anticoagulant pathways, in particular, the protein C system. In this study, 602 (265 female, 337 male) patients with suspected thrombosis, arterial or venous, were referred to King Hussein Medical Center in Amman, Jordan. The prevalence of hereditary deficiencies of antithrombin (AT), protein S (PS), and protein C (PC) were studied over a seven-year period (1993-2000). Activated protein C (APC-R) resistance subjects were studied over four years (1996-2000). The mean age was 30 years in females and 42 years in males. A diagnosis was established in 22.4% (n = 135) of the subjects (20.3% venous, 2.1% arterial). Protein C deficiency was found in 3.8%, protein S deficiency in 2.3% and antithrombin deficiency in 1.4% of our sample group. An APC-R problem was seen in 23.0% (n = 89) of the surveyed population. Out of the APC-R patients, 75.0% had the DNA analysis of a factor V Leiden mutation present. Of the subjects found to have the mutation 87.0% were heterozygous and 13.0% were homozygous. These results confirm that APC-R, as a result of factor V Leiden mutation, is the most prevalent cause of thrombosis, and thrombophilia is related to venous, not arterial, thrombosis.     

The screening and treatment of undiagnosed depression in patients with chronic obstructive pulmonary disease (COPD) in a general practice.

AIMS AND OBJECTIVES: To screen for, and to treat, depression in COPD patients in a general practice surgery, and to test the feasibility of the screening method. METHODS: We sent The Beck Depression Inventory (BDI) Short-Form Questionnaire to all patients on the COPD register (n=69) by post, excluding those already diagnosed with depression (n=3). We sent appointments to all responders with moderate to severe depression and offered them treatment including antidepressants and pulmonary rehabilitation if the diagnosis was confirmed. RESULTS: Of the 66 patients to whom we sent questionnaires, 43 were returned completed and 13 of these had significant depression (30%). 10 of these patients were contactable and attended for review. The diagnosis of depression was confirmed in all 10 cases. Treatment options were discussed; five chose antidepressant medication, three chose pulmonary rehabilitation and two declined treatment. CONCLUSION: We identified and treated a significant number of depressed COPD patients in a general practice setting using this screening method. This method could have wider applications for screening, although further trials are needed.     

Frontotemporal dementia and parkinsonism linked to chromosome 17 with the N279K tau mutation

We present a case of frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP‐17) harboring the N279K mutation in the MAPT gene from the family known as pallido‐ponto‐nigral degeneration (PPND). This 49‐year‐old man was followed for 17 years. He presented at age 41 years with left leg stiffness and en‐bloc turning. During the course of his illness he developed a constellation of symptoms including parkinsonism, pyramidal signs, vertical gaze palsy, dysphagia, dystonia, personality and cognitive dysfunction, weight loss and mutism. Gross neuropathological examination showed mild atrophy of the cerebral cortex, hippocampal formation, amygdala, thalamus, subthalamic nucleus and depigmentation of the substantia nigra. Microscopy revealed neuronal loss and gliosis in the same regions. Tau immunohistochemistry showed pretangles, numerous threads, grain‐like structures and oligodendroglial tau‐positive inclusions (“coiled bodies”). In the spinal cord the tau pathology was more abundant in gray than white matter. Pretangles and threads were present in the anterior and, to a lesser extent, in the posterior horns. FTDP‐17 should be suspected in patients with a history of familial parkinsonism combined with behavioral and cognitive changes, onset before age 65 years and an aggressive clinical course.     

Estimation of gestational age by last menstrual period, by ultrasound scan and by SP1 concentration: comparisons with date of delivery

The date of delivery in 62 normal pregnant women was predicted by last menstrual period, by ultrasound scan and by the serum concentration of Schwangerschaftsprotein 1 (SP1). It was found that SP1 concentration in the first trimester gave as reliable an indication of when labour would occur as did the last menstrual period or ultrasound scan.     

In Vivo Effects of TRH, T3 and cGH on Antibody Production and T- and B-Lymphocytes Proliferation in Immature Male Chickens

Newly hatched White Leghorn male chicks were used in this study. Different doses of T₃ (O.1 or 1 ppm) or TRH (1 or 5 ppm) were administered in the feed for an 8-week period. Chicken growth hormone (cGH) (10 μg/kg BW) was injected (i.v.) into a different group of chicks twice daily for 1 week starting at 7 weeks of age. A different group received both T₃ (0.1 and 1 ppm) and cGH. Serum concentrations of T₄, T₃ and GH, antibody production against sheep red blood cells (SRBC) and Brucella Abortus (BA), and in vitro proliferative response of both T- and B-lymphocytes to mitogenic stimulation were measured. Supplementation of T₃ (1 ppm) significantly lowered T₄ and increased T₃ concentrations. No effect of any hormone treatment on antibody production was observed. T₃ supplementation and cGH injection alone or with T₃ (0.1 ppm) significantly increased blastogenic response of lymphocytes to either Con-A or LPS mitogenic stimulation. It was concluded that T₃ and GH are involved in lymphocyte activity of chickens.
