Intracerebral haematoma in an infant with haemophilia A

Summary A nine-weeks-old infant with haemophilia A developed an intracerebral haematoma. Intracranial operation and removal of the haematoma were performed safely under the cover of highly potent AHF cryoprecipitate. Computerized tomography of the brain is very useful for neurosurgical care of the haemophiliac patients as a noninvasive and atraumatic method of examination. The literature of intracranial operations in infants with haemophilia A under the age of one year is reviewed.     

No interference of rheumatoid factor(s) with toxoplasmosis IgM determination in infancy

Sera from 263 newborns and infants suspected of congenital toxoplasmosis were tested for the presence of rheumatoid factor (RF) by the latex agglutination test, of which 40 were also tested by the enzyme-linked immunosorbent assay (ELISA). RF was detected in only one serum sample (0.38%), suggesting that false-positive results of the IgM-indirect fluorescent antibody test and the IgM-ELISA due to RF is most unusual in infancy.     

Hypospadias sine hypospadias

Summary There are four forms of chordee that do not involve hypospadias: cutaneous chordee, fibrous chordee, corporocavernosal chordee, and congenital short urethra. From 1981 to 1991, 214 patients aged 18 months to 20 years underwent surgical treatment. Among these, 29 individuals developed a crippled penis due to the failure of surgery for the hypospadias sine hypospadias anomaly. This report describes the surgical repair of hypospadias sine hypospadias, whereby the operative approach is closely related to the type of anomaly involved and should thus be highly individualized. The rate of complications encountered in the present study was 11.2%.     

Clinical characteristics of haemorrhagic fever with renal syndrome in children

From January 1988 to September 1989, seven patients (4 girls and 3 boys, aged 3–12 years) with haemorrhagic fever with renal syndrome (HFRS) were hospitalised at the University Children's Hospital in Belgrade. In four patients the disease appeared as a family outbreak, the others were sporadic cases. In six patients the clinical presentation was suggestive of HFRS, as they had fever with headache, myalgia, sore throat and gastrointestinal illness followed by renal abnormalities. However, severe haemorrhagic syndrome with petechia, haematoma, haematemesis and melaena was present in one patient only. Renal disease presented as nephritic syndrome and/or acute renal failure. Five patients recovered after 2–3 weeks without sequellae, one patient had decreased renal function 17 months after the start of the disease and the remaining patient died. In six patients the diagnosis of HFRS was confirmed serologically by a significant rise in antibody titres against hantaviruses, while in the patient with the fatal and fulminant course of the disease, the diagnosis was established on the basis of epidemiological and autopsy findings. We suggest that children living in endemic areas who develop an ill-defined, febrile and gastrointestinal disease with renal dysfunction should be evaluated for HFRS.     

Studies of chemical and biological properties of 99mTc-DMS (dimercaptosuccinic acid) — Renal imaging agent

Studies of the chemistry of preparation of tin chelate 2.3-dimercaptosuccinic acid (DMS) complexed with ^99mTc with respect to its biological properties have been made. We have varied molar ratio of reactants (DMS:Sn/II/), concentration of Sn-DMS chelate and pH of ^99mTc-DMS injection solution and examined their influence on biodistribution. Biodynamics of labeled solution at time intervals of from 0.5 to 4 h have also been measured. Animal experiments were carried out on mice and rats.Radiochemical purity was checked by paper chromatography, thin-layer chromatography, and gel-filtration through Bio-Gel P-2.A sterile, pyrogen-free lyophilized kit for labeling, stable for 6 months, was made on the basis of achieved results.The results of its clinical application are also reported.Report presented at the I European Congress of Nuclear Medicine, Lausanne, May 12/15, 1976     

Posttraumatic stress disorder and platelet serotonin measures

The role of serotonin (5HT) in the pathophysiology of posttraumatic stress disorder (PTSD) has been suggested by the overlap in clinical symptoms between PTSD and psychiatric conditions in which a serotonin dysfunction is implicated, as well as by the therapeutic efficiency of 5HT-related drugs (antidepressants, selective serotonin reuptake inhibitors and monoamine oxidase inhibitors) in alleviating symptoms in PTSD. In the present study, the blood platelet, which has been proposed as a peripheral model for the central serotonergic neurons, has been used to search for alterations in 5HT mechanisms in PTSD. Platelet serotonin level and kinetics of serotonin transporter and monoamine oxidase (MAO-B) were assessed in 63 combat-related PTSD patients and 43 sex and age-matched control subjects. A significant reduction in maximal velocity of platelet MAO-B (approx. 30%), with no changes in the enzyme affinity was observed in our patient sample. Conversely, no alterations in kinetic parameters (V(max), K(m)) of platelet serotonin transporter, as well as in platelet 5HT level, were found in the PTSD group.     

War wounds to the foot

Thirty-nine patients with foot injuries were admitted to the Clinic for Orthopedic Surgery in Lovran during the war against Croatia. All of them were soldiers wounded by antipersonnel mines. All of the patients were treated using the same protocol. Primary wound care included debridement, necrectomy, and three-dimensional external fixation with or without Kirschner wires. External fixation facilitated postoperative wound care, prevented vicious contracture position, and made fracture healing possible with early weight bearing.     

Increased activity of lymph node cells in experimental thermal injury: changes in accessory cells in injured area-draining lymph nodes

Accessory cell content and some of their functional characteristics were determined in regional lymph nodes which drain burn injury (DLN) in rats. Increase in percentages of non-specific esterase-positive cells and NBT+ macrophages and in numbers of dendritic cells were noted in cytospin preparations of draining lymph node cells (DLC) 24 and 72 h following thermal injury. An accumulation of B cells was also noted in the DLN paracortex region at these time points. Enrichment of ED1+ (rat macrophage marker) cells was noted in the adherent DLC population. Increased activity of interleukin-1 (IL-1) in conditioned medium from adherent DLC population and the increased stimulatory capacity of whole DLC or dendritic cell enriched-DLC fraction were noted in functional assays. Enrichment in accessory cells and an increase in their functional activity could contribute to the endogenous activity of regional lymph nodes which drain burned areas.
