Because of the excellent blood supply to the head region, superficial lacerations to the soft tissue structures of the head generally heal rapidly without treatment. Lacerations of the equine tongue frequently go unnoticed because difficulty in eating usually is not apparent. The majority of lacerations heal if left untreated, with no loss in function. Surgical repair is indicated to promote healing and prevent deformity, to amputate a severely compromised apex, and to alter a scar or defect that is unacceptable to the owner. Surgical principles to be adhered to include thorough debridement and copious lavage, multiple layer closure, and placement of tension sutures away from the primary suture line and tied on the dorsum of the tongue. Full-thickness lip lacerations should be repaired using multiple-layer closure and tension sutures tied on the skin surface away from the primary suture line. Reconstructive techniques have been described for extensive lip lacerations when primary repair was inadequate or tissue loss was severe. Thorough evaluation of the equine lid, adnexa, and orbit is essential in determining severity of injury and appropriate treatment methods as well as for establishment of a prognosis. The injury may be minor or more severe, leading to blindness, disfigurement, or loss of the eye itself. Depression fractures involving the frontal, maxillary, or nasal bones are frequently open fractures. Skin abrasions, epistaxis, facial deformity, crepitus, and pain are clinical signs seen with this type of injury. Bone and soft tissue reconstruction should be performed to minimize potential complications. Facial fractures left untreated can result in facial deformity, sequestration, sinusitis, and osteomyelitis.

The Cook County Hospital, Chicago, Illinois, protocol for the management of orbital fractures is presented. Diplopia which fails to resolve in 1 week or appears after oedema subsides, enophthalmos or radiographic depression of the orbital floor, associated tripod fracture deformity, or purulent maxillary sinusitis are indications for surgery. The surgical procedure is a modification of the maxillary sinus approach, which includes the use of iodoform gauze packing, nasal antrostomy, a double layer oral closure and prophylactic antibiotics. A review of 102 patients treated surgically over a 6-year period is presented. Post-operative diplopia was 9% and there were minor complications in 3%, which were significantly lower than previously reported series of orbital fractures treated either non-operatively, or through an orbital exploration approach. No patient treated non-operatively required surgery in the future. The protocol presented can eliminate unnecessary exploration and yields excellent results with a simple surgical procedure.

Ventilation and drainage are the two essential intrinsic functions of the sinus. Both of them are dependent upon the permeability of the ostium, whose caliber is extremely variable with respect to anatomical factors, and dynamic factors associated with the vasomotricity of the mucous membrane. In many subjects the ostial permeability is precarious, thus explaining the frequency of inflammatory sinus reactions. These are due, as the level of the middle ear, either to a transostial inoculation of pathogenic germs creating a microbial sinusitis, or to an ostial obstruction responsible for a hypoxia, a hypercapnia, and a local depression creating a a vacuo sinusitis. The second situation leads to conditions that are favorable for the development of the first and vice versa.

This study examined the hypothesis that older persons who currently report illness from environmental chemical odors (cacosmia) may have experienced higher levels of stress early in life than did noncacosmic controls. The hypothesis derives from a time-dependent sensitization (TDS) model for cacosmia (Bell et al 1992) that predicts a relative interchangeability of stress and chemicals in inducing and eliciting sensitized responses in vulnerable individuals. Subjects were selected from those in the top 24% (cacosmic) and bottom 27% (noncacosmic) of a sample of 192 older adults (mean age 73.8 years) for self-reported frequency of illness form the odors of pesticide, car exhaust, paint, perfume, and new carpet. As in previous investigations, cacosmics were younger, more depressed, and more shy; cacosmics also included a higher proportion of women (83% versus 61%). As predicted, cacosmics rated themselves higher in stress for the first four decades of their lives, but not the recent past or present, even after controlling for depression, anxiety, hostility, shyness, age, and gender. Cacosmics reported increased prevalence of physician-diagnosed nasal allergies, breast cysts, hypothyroidism, sinusitis, food sensitivities, irritable bowel, and migraine headache. Only 4% of the overall sample (including 9% of the cacosmics) acknowledged the controversial physician diagnosis of "chemical sensitivity." The replicated observation of greater shyness in cacosmics is consistent with the ability of hyperreactivity to novelty to predict enhanced susceptibility to TDS from low levels of pharmacological agents in animals. The findings support a TDS model for cacosmia and suggest that cacosmia as a symptom identifies a large subset of the nonindustrial population with significant psychophysiological health problems that merit further objective examination.

Six patients were treated for gradual onset of enophthalmos, a deep superior sulcus and globe ptosis. There was no history of orbital trauma or sinusitis. CT scan showed an opacified shrunken maxillary sinus with dehiscence and depression of the orbital floor and downward displacement of the orbital contents. Pathological review of the surgical specimens showed a respiratory mucosal lining with thick mucoid secretions, new bone formation, but no purulence. The etiology is thought to be maxillary sinus mucocele. Surgical treatment with an otolaryngologist consisted of a Caldwell-Luc procedure to evacuate the maxillary sinus with nasal antrostomy and an orbital floor exploration with insertion of a methylmethacrylate implant molded at the time of surgery to reform the orbital floor and reposition the globe. Follow-up of 2 1/2-4 years shows excellent functional and cosmetic results.

This study examined the incidence of infectious and neoplastic diseases among 222 HIV-seronegative gay men who participated in the Natural History of AIDS Psychosocial Study. Those who concealed the expression of their homosexual identity experienced a significantly higher incidence of cancer (odds ratio = 3.18) and several infectious diseases (pneumonia, bronchitis, sinusitis, and tuberculosis; odds ratio = 2.91) over a 5-year follow-up period. These effects could not be attributed to differences in age, ethnicity, socioeconomic status, repressive coping style, health-relevant behavioral patterns (e.g., drug use, exercise), anxiety, depression, or reporting biases (e.g., negative affectivity, social desirability). Results are interpreted in the context of previous data linking concealed homosexual identity to other physical health outcomes (e.g., HIV progression and psychosomatic symptomatology) and theories linking psychological inhibition to physical illness.

Seven 18-wk-old pullets from a commercial layer flock experiencing increased mortality associated with neurologic and respiratory symptoms were submitted to the California Veterinary Diagnostic Laboratory System at the Turlock Branch for necropsy. Clinical signs included depression, torticollis, swollen eyelids, conjunctivitis, and sinusitis. Meningoencephalitis and suppurative inflammation of the cranial air spaces were found on histopathology. The brain, sinuses, and air spaces of the cranium were infected with Pasteurella multocida. Complicating the condition was Mycoplasma gallisepticum infecting the sinus and paramyxovirus-I affecting the trachea.

Consumer choice research has shown that, contrary to normative theory, the introduction of an inferior alternative to an existing choice set can increase the likelihood that one of the original alternatives will be chosen. This phenomenon, the attraction effect, is relevant to physician decision making, particularly when the physician is in the role of a consumer who must make decisions about prescribing medications when a number of alternatives are available. To investigate the attraction effect in physician decision making, 40 internal medicine residents reviewed three patient cases (concerning depression, sinusitis, and vaginitis) and then chose the most appropriate medication for each patient. In some versions of the cases, two medication options were available. Other versions included a third medication (the decoy) that was inferior in every way to one of the original options (the target) but not to the other (the competitor). The results showed that addition of the "decoy" medication increased the likelihood of choosing the target medication. That is, the attraction effect does occur in physicians' decisions about medications. Physicians should be aware of this bias when evaluating or suggesting several similarly attractive medications or treatment options for the same medical condition.

The goal of this study is to determine the prevalence of 23 common diseases in subjects with a chronic airway obstruction and in controls. All subjects with a known diagnosis by their general practitioner of asthma or chronic obstructive pulmonary disease (COPD), and who were 40 years and older were selected (n = 1145). Subjects who were willing to participate (n = 591) and who appeared to have an irreversible airway obstruction (n = 290) were included. To recruit controls, a random sample was taken of 676 individuals who were 40 years and older and who were not diagnosed as having asthma or COPD by their general practitioner. Of these 676 individuals 421 were willing to participate. The presence of diseases was determined by using a questionnaire. One hundred and ninety-four subjects (73%) and 229 controls (63%) were shown to be suffering from one or more (other) diseases. In both groups, locomotive diseases, high blood pressure, insomnia and heart disease were most common. Locomotive diseases, insomnia, sinusitis, migraine, depression, stomach or duodenal ulcers and cancer were significantly more common in the subject group than in the control group. For both clinical and research purposes, it is important to consider the presence of diseases in patients with a chronic airway obstruction.

Beginning at the end of March 1999, a syndrome characterized by severe depression, anorexia, fever, and respiratory and enteric symptoms appeared in flocks of turkeys and, to a lesser extent, of chickens in the densely populated poultry-rearing regions of northeast Italy. The disease was characterized by sinusitis, tracheitis, peritonitis, and pancreatitis. The mortality varied between 5% and 90%. The disease was diagnosed as low pathogenic avian influenza, H7N1 serotype. After a summer period of declining cases, the disease reappeared in autumn exclusively in turkeys. Since the middle of December 1999, many farms of chickens, turkeys, and guinea fowl were abruptly affected by a highly pathogenic H7N1 virus, with very severe depression and mortality up to 100% in a few days. By the end of March 2000, nearly 500 farms, representing over 15 million birds, were affected or depopulated. To date, control measures have focused on improved biosecurity measures. Vaccine was not allowed, but its use was debated.
