[Contribution of ultrasound in the diagnosis of the complications of intramuscular injection in children].

During a prospective study conducted at the rehabilitation Center of the physically handicapped persons and at the mother-child Hospital in Bamako, the authors report 50 cases of neuromuscular complications of the quinine intramuscular injection in the child. The scan revealed muscular calcifications in 37 cases (740%), abscesses, in 7 cases (14%) and muscular inflammations in 6 cases (12%). Xray of the affected limb was not systematic: it has been performed in four children in the case of a subjacent bone involment. It showed calcifications in two cases. If muscular abscess is easily diagnosed by clinical exam it is not the case for calcifications. The scan allows to set up a precise mapping of the muscular lesions, to determine their type and size. It also helps the clinicians in their therapeutic attitude. Medical treatment associated with rehabilitation has been carried out in 40 patients (80%) and surgery in 10 patients (20%).

[Combination therapy of daily intramuscular injection of interferon-alpha and oral administration of fluorouracil for advanced renal cell carcinoma].

BACKGROUND: To achieve optimum drug delivery of Interferon-alpha in treatment of renal cell carcinoma, a regimen consisting of its daily intramuscular administration, in combination with oral fluorouracil, was designed and carried out. Its efficacy is examined retrospectively. METHODS: In our department 7 patients with disseminated renal cell carcinoma were treated with daily intramuscular injection of interferon-alpha (3 x 10(6) IU) and daily oral administration of fluorouracil. All patient was nehprectomized before initiation of the regimen. RESULTS: Two patients achieved complete, and three patients achieved partial response radiographically (Overall response rate 71%). Metastatic sites of responders were lung (4) and pleura (2). The time required until response was 3.9 (median 5.4) months. In two responders, new lesions appeared in other organs despite durable response in initial pulmonary metastatic sites. There were two no-responders, one patient is alive with stable disease and the other patient died for progression of the disease. In all, two patients died of disease, one died for other cause, one surviving without evidence of disease, and three are surviving with disease. No significant side effect was noted in these seven patients. CONCLUSIONS: This regimen can be carried out on outpatient basis and considerable response can be expected for pulmonary and pleural lesions.

Ocular penetration of amikacin following intramuscular injection.

Amikacin sulfate was given intramuscularly (IM) (7.5 mg/kg) to study its ocular penetration in man. Seventy-three patients with cataracts received a single dose and 35 received two doses given 5 1/2 to 12 hours apart. After a single dose the aqueous humor levels of the antibiotic between two and ten hours ranged from 0.15 to 3.10 mg/L (average and median, 1.0 mg/L). Two doses given 5 1/2 to eight hours apart produced an average level of 3.5 mg/L (range, 0.91 to 8.31 mg/L). When the second dose was given nine to 12 hours after the first, the aqueous humor levels were similar to those found for a single dose. Aqueous humor concentrations of 1.0 mg/L of amikacin would be expected to be bactericidal for most gram-negative bacterial pathogens, whereas levels of 3.5 mg/L would inhibit most strains of Staphylococcus aureus and many strains of Pseudomonas aeruginosa.

HI-6 and 2-PAM in sheep: pharmacokinetics and effects on muscle tissue following intramuscular injection.

The pharmacokinetics of 2-PAM, a component of the current nerve agent antidote therapy for U.S. military forces was compared to the pharmacokinetics of another acetylcholinesterase reactivator HI-6. Additionally, the effects of these compounds on muscle tissue following intramuscular injection was examined. Plasma concentrations of the oximes were determined by HPLC. Plasma concentration-time profiles for both oximes fit a one-compartment open model with first-order absorption and elimination. The results demonstrate that the half-time of absorption of HI-6 was significantly higher than that for 2-PAM. Musculoirritancy was assessed on the basis of quantitative histological examinations of the injection sites and by the measurement of serum creatinine phosphokinase. Comparison of the scores from the histological sections demonstrate no difference between the two oximes. Serum creatinine phosphokinase values were elevated following injections of HI-6, but were not consistently elevated following the 2-PAM injections.

Polyvinylpyrrolidone (povidone) storage in RX-damaged skin following procaine-povidone intramuscular injections.

A man, aged 67, has been treated in 1968 by X-rays for a basal-cell carcinoma of the back. The treatment was followed by an ulcerative radiodermatitis. 3 years later, the patient was treated by ten intramuscular injections of procaine-polyvinylpyrrolidone (or procaine-povidone) for sciatic neuralgia. An orange infiltration appeared progressively around the radiodermatitis. The area was excised in 1979 and polyvinylpyrrolidone (povidone) storage, responsible for the ring-shaped orange hue, could be demonstrated in the dermis and subcutaneous fat. Special stainings confirmed the presumed chemical nature of the deposits. 3 cases of povidone pseudotumours following procaine-povidone injections had been described previously. The preferential deposit of povidone in RX-damaged skin is discussed.

[Pulmonary and bronchial kinetics of cefuroxime after a single 500 mg intramuscular injection].

Thirty-two patients (28 males; mean age 56 +/- 10 years) who were undergoing bronchopulmonary exeresis surgery were included in this study of the pulmonary (pulm), bronchial (br), and plasma (pl) kinetics of cefuroxime after a single 500 mg intramuscular injection. Twenty-nine bronchial specimens and 38 pulmonary and plasma specimens were taken on average at the following times after the cefuroxime injection: 1 h, 2 h, 3 h, 4 h, 6 h, 8 h, and 10 h. Cefuroxime was assayed using HPLC on ground tissues, with a correction for contamination by blood. Peak concentrations (C) were found after one hour (Cpl = 11.6 +/- 0.8 micrograms/ml; Cpulm = 7.3 +/- 3.3 micrograms/g; Cbr = 3.7 +/- 1.5 micrograms/g) with the following residual values after 8 hours: Cpl = 0.94 +/- 1.04 micrograms/ml, Cpulm = 0.49 +/- 0.45 micrograms/g, Cbr = 0.15 +/- 0.07 micrograms/g (means +/- 1 SD). Elimination kinetics were monoexponential and similar in plasma, lung tissue and bronchial tissue (elimination half-lives: 1.74 h, 1.66 h, and 1.56 h, respectively), suggesting that all three elements belong to the same pharmacokinetic compartment. Mean intrapolated area-under-the-curve values (AUC) were 33.58 micrograms.ml-1.h (plasma), 20.08 micrograms.g-1.h (lung), and 10.22 micrograms/g-1.h (bronchus). The AUCpulm/AUCpl and AUCbr/AUCpl ratios were 0.60 and 0.30, respectively, in agreement with mean values of tissue level/simultaneous plasma level ratios (lung: 0.59; bronchus: 0.33).

Calcium metabolism in cows receiving an intramuscular injection of 1,25-dihydroxyvitamin D3 combined with prostaglandin F(2alpha) closely before parturition.

To determine the effect of exogenous 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] combined with induced parturition on calcium (Ca) metabolism, cows received a single intramuscular injection of 1,25(OH)2D3 and prostaglandin F(2alpha) (PGF(2alpha)) closely before calving. Ten late-pregnant, multiparous Holstein cows were assigned to 1,25(OH)2D3 group (five treated with both 1,25(OH)2D3 and PGF(2alpha)) and control group (five treated with PGF(2alpha)). 1,25(OH)2D3 group showed an increase in plasma Ca concentration around parturition, whereas control group revealed a decrease in plasma Ca level. Plasma Ca concentration in 1,25(OH)2D3 group were significantly higher than that in control group during -0.5 to 3 days after parturition.

[Benefits and risks of intramuscular injection. Are expectations of physicians and patients irrational?].

Although unsupported by scientific evidence, there is in Germany a traditional attitude of expectancy vis-a-vis the efficacy of injections which often results in this form of application being given preference over the oral route. With respect to both the indication and the observance of disinfection time and proper injection technique, adherence to existing guide lines would appear to be urgently necessary within the framework of quality assurance relating to this common form of treatment. After all, intramuscular injection continues to be high on the list of causes of treatment errors.

Acquired gluteal myospherulosis secondary to intramuscular injections of petrolatum-based hormones: a case report diagnosed by fine-needle aspiration cytology.

A case of acquired myospherulosis of the right gluteal region diagnosed by FNA cytology is reported in a woman who had received a series of intramuscular injections of petrolatum-based hormones. The lesion is characterized by inflammatory pseudocystic nodules containing saccular formations with erythrocytes or "bags of marbles." It results from a physical process similar to the emulsion phenomenon between nonresorbent oily material and plasma. This process gives rise to sequestration of blood corpuscles by oily materials and thus development of foreign body granulomas.

Clinical manifestations and neurodevelopmental outcome following an event of accidental intramuscular injection of atracurium in newborns.

UNLABELLED: Pediatric populations are at risk for medication errors that may be associated with mortality and disability. The purpose of this study was to describe the clinical manifestations of seven newborns following an event of accidental intramuscular injection of atracurium and to assess the impact on neurodevelopmental outcome. This study enrolled seven newborns who were accidentally administered 10 mg of atracurium, equivalent to 2.6-3.3 mg/kg, in a local perinatal clinic. Accident reports and hospital records were reviewed to obtain the history and medical data for the event. The survivors were prospectively examined for their growth, health and neurodevelopment until 24 months of age. All newborns showed immediate apnea and cyanosis requiring resuscitation after atracurium injection and presented with respiratory failure and flaccid paralysis on arrival for emergency medical services. One newborn was asystolic despite resuscitation and died of multiple organ failure. Of the five survivors available for follow-up, all achieved favorable growth outcomes. However, four showed mild to significant delay in development; and two manifested mild hypomyelination of cerebral white matter on the brain magnetic resonance imaging. CONCLUSION: Newborns accidentally injected with high doses of atracurium are at risk of death and neurodevelopmental delay. The serious clinical manifestations, developmental delay and cerebral hypomyelination were most likely due to insufficient immediate respiratory assistance following atracurium injection.

Release of vasoactive intestinal peptide by intraduodenal infusion of HCl or fat and intramuscular injection of neostigmine in man.

A highly sensitive radioimmunoassay system for plasma vasoactive intestinal peptide (VIP) was developed to examine the effect of intraduodenal infusion of HCl or fat on the plasma VIP levels in healthy subjects, and the effect of intramuscular injection of neostigmine in patients with irritable bowel syndrome (IBS). Intraduodenal infusion of 100 ml of 0.1 N HCl or 10 g fat caused a significant rise in plasma VIP level. Neostigmine (12.5 micrograms/kg) produced a significant rise in plasma VIP level, and the plasma VIP response to neostigmine was significantly greater in the IBS group than in the normal group. These results suggest that VIP might play a role in the pathophysiology of IBS.

Rabbit EPO gene and cDNA: expression of rabbit EPO after intramuscular injection of pDNA.

Erythropoietin (EPO) cDNA was cloned from kidney total RNA of a NZW rabbit. The cDNA comprises a 588-bp open reading frame encoding a 195 amino acid protein with distinguishable regions of high of homology to other mammalian EPOs. Intramuscular injection of mice with a rabbit EPO expression plasmid resulted in a significant hematocrit increase. A rabbit genomic DNA fragment was also cloned using the rabbit EPO cDNA. This 4312-bp genomic DNA fragment contains sequences homologous to the mouse EPO promoter and hypoxia-responsive enhancer. In addition, the genomic DNA also presents a high degree of conservation to other regions involved in hypoxia response. Sequence divergence in the 3' UTR may indicate differences in regulation of mRNA stability or response to low oxygen tension.

Penicillin concentrations in serum and cerebrospinal fluid after intramuscular injection of aqueous procaine penicillin 0.6 MU with and without probenecid.

Paired specimens of cerebrospinal fluid and serum were taken from 21 patients to estimate penicillin concentrations two to three hours after the last dose of a course of 14-21 daily intramuscular injections of procaine penicillin 0.6 MU. Of 10 patients treated with procaine penicillin alone, eight had no detectable penicillin and two had sub-treponemicidal concentrations (less than 0.018 mg/l) in the cerebrospinal fluid. Of 11 patients treated with procaine penicillin as above and probenecid 2 g a day by mouth, three had no detectable penicillin, two had sub-treponemicidal concentrations, and six had treponemicidal concentrations of penicillin in the cerebrospinal fluid. All 21 patients had treponemicidal concentrations of penicillin in the serum. This dose of procaine penicillin alone or with probenecid is therefore not recommended for treating neurosyphilis.

Exuberant local tissue reaction to intramuscular injection of nandrolone decanoate (Deca-Durabolin)--a steroid compound in a sesame seed oil base--mimicking soft tissue malignant tumors: a case report and review of the literature.

We present an unusual pseudotumor that formed in reaction to self-administered intramuscular injections of an anabolic steroid, nandrolone decanoate (Deca-Durabolin) in a young soldier. The histopathologic features which closely mimicked several malignant neoplasms could have led to an incorrect diagnosis of malignancy and unnecessary extensive surgery. To our knowledge, this phenomenon has not been previously reported.

[Treatment of macroprolactinomas with delayed bromocriptine. Effectiveness of a single intramuscular injection].

The aim of the present study was to evaluate the effectiveness and tolerance of a new pharmaceutical preparation of long acting bromocryptine (bromocryptine depot of L.A.), characterized by the slow release of bromocryptine during 4 or 6 weeks after a deep intramuscular injection. It was administered to 9 patients with macroprolactinoma, 7 of which had visual abnormalities. The tolerance of the drug was excellent, and only one patient had nausea within the first 24 hours. In all cases, PRL values fell between 40% and 97%. All patients with visual abnormalities, including 2 patients with cranial nerve palsy (IIIth and VIIth pairs) returned to normal or improved. In the CT controls carried out after 4 weeks of therapy a reduction in tumor size was observed in 7 of 9 patients. Two patients were operated through the transesphenoidal route, PRL being demonstrated in the immunohistochemical study of the resected specimen. Subsequently, all patients received oral bromocryptine therapy with perfect tolerance. The results show that parenteral long acting bromocryptine is an effective, well tolerated and convenient way to start the therapy of macroprolactinoma, even when severe visual abnormalities are present.

Pathological and biochemical changes induced in mice after intramuscular injection of venom from newborn specimens of the snake Bothrops asper (Terciopelo).

Venom from newborn Bothrops asper snakes has higher lethal, hemorrhagic, edema-forming, proteolytic and defibrinating activities than venom from adult B. asper specimens. Electrophoretic analysis confirmed the variation between these venoms. Intramuscular injection of 100 micrograms of venom from newborn specimens in mice induced defibrination, together with moderate increments of serum levels of lactate dehydrogenase, creatine kinase, hemoglobin and total proteins. A conspicuous hemorrhage developed in injected muscle rapidly after envenomation, probably due to a drastic alteration in capillaries and larger blood vessels. Other histological alterations included moderate myonecrosis, lung collapse and prominent renal damage, characterized by tubular necrosis and hyalinization. Polyvalent antivenom effectively neutralized lethal, hemorrhagic and indirect hemolytic activities of newborn B. asper venom, although requiring higher antivenom doses than neutralization of venom from adult B. asper.

Impact of osmolality on burning sensations during and immediately after intramuscular injection of 0.5 ml of vaccine suspensions in healthy adults.

A randomised placebo controlled double-blind cross-over trial was performed on twenty healthy adults to assess the effect of osmolality (300,600,850 and 1100 mOsm) on local tolerance of an intramuscular injection (0.5 ml) of five suspensions containing the same components as the excipients of a combined Diphtheria-Tetanus-acellular Pertussis-inactivated Poliomyelitis-Haemophilus influenzae type b paediatric vaccine (DtacP-IPV-Hib, PENTAVAC). The results did not show any dose-effect relationship between burning or pain sensations and the different osmolalities tested. Although mild and not clinically relevant, these sensations seemed to occur more frequently following injection of an isotonic saline solution (P<0.05). Thus, the osmolality of vaccine like suspensions does not appear to be a potential cause of local pain or burning sensation after their administration.

Iron supplementation: oral tablets versus intramuscular injection.

Non-anemic, iron depleted women were randomly assigned to an injection group (IG) or oral group (OG) to assess which method is more efficient for increasing iron stores over a short time period. IG received a course of 5 x 2 mL intramuscular injections over 10 d, and OG received one tablet daily for 30 d. Fourteen, 21 and 28 d after commencing supplementation, ferritin concentration in OG significantly increased from baseline (means +/- standard error: 27 +/- 3 to 40 +/- 5 to 41 +/- 5 to 41 +/- 5 microg/L; P < 0.01). Similarly, on days 15, 20, and 28 post the first injection, ferritin concentration in IG significantly increased from baseline (means +/- standard error: 20 +/- 2 to 71 +/- 17 to 63 +/- 11 to 63 +/- 7 microg/L; P < 0.01), and was also significantly greater than OG at day 15 and 28 (P < 0.05). Iron injections are significantly more effective (both in time and degree of increase) in improving ferritin levels over 30 d than oral tablets.
