Insect Bites and Stings*

Most insects have a stinging apparatus at the tail end of their abdominal segment and can deliver venom. The venom can usually result in pain, erythema, abscess, or allergic reaction in human tissues such as the skin and even the lips. The presentation of lip abscess, especially in the vermilion, is rare and needs to be appropriately managed. A 39-year-old prediabetic male presented with a swollen right lower lip stung by an insect six days before the consult. The swelling started as a vesicle which became bigger, then burst, exuding a yellowish fluid and blood. The swollen area became more significant, and pain was felt. The clinical presentation was that of a lower lip abscess. Adequate antibiotics were prescribed along with a corticosteroid and a topical antiseptic. The treatment was essential to prevent the dissemination of infection and the likelihood of tissue necrosis. This case report is presented as a rare clinical case of a lower lip abscess due to an insect sting with spontaneous drainage after treatment in a prediabetic male. The dentist and clinician needed to identify this condition and to manage the case properly.

Reactions to Hymenoptera insect stings are common. While most are self-limited, some induce systemic allergic reactions or anaphylaxis. Prompt recognition, diagnosis, and treatment of these reactions are important for improving quality-of-life and reducing the risk of future sting reactions. This review summarizes the current recommendations to diagnose and treat Hymenoptera sting induced allergic reactions and highlights considerations for various populations throughout the world.

Snake bite during pregnancy is rare condition, and when it occurs there are two patients, mother and fetus. Timing is particularly important for pregnant women bitten by a snake. The earlier in the pregnancy the bite occurs, the more hazard to the fetus there is, and there are case reports of snake-bite-induced abortion and malformation of the fetus. The usefulness of antivenin during pregnancy is debatable. We report a case of snake bite during thirdtrimester pregnancy in a patient with general symptoms of envenomation and progressing edema in the bitten leg who was successfully treated with an emergency Caesarian section following the administration of antivenin.

BACKGROUND: Mosquito bite is a common dermatological complaint with various treatments but with no gold standard treatment regimen. OBJECTIVE: To compare the safety and efficacy of 0.025% capsaicin cream against 1% hydrocortisone cream and placebo as anti-inflammatory and anti-pruritic preparation for mosquito bites. METHODS: Seventy-five volunteers were enrolled in the placebo-controlled trial and randomized into three treatment groups. They were exposed to laboratory-reared mosquitoes to incur bites and to apply the designated cream. Anti-inflammatory and anti-pruritic effects were determined by mean lesion size, physician's global assessment, pruritus intensity score and 100mm visual analog scale. RESULTS: The mean lesion size and physician's global assessment, pruritus intensity score and visual analog scale showed no significant difference between 0.025% capsaicin and 1% hydrocortisone and they were both found to be superior to placebo (p-value< 0.001 using repeated measures of ANOVA; Kruskal-Wallis test). CONCLUSION: 0.025% capsaicin is comparable to 1% hydrocortisone as an anti-inflammatory and anti-pruritic preparation for mosquito bites.

PURPOSE: There have been local wound complications in patients who have received first aid after venomous snake bites. Yet first aid in relation to local wound complications has not been well studied. METHODS: We conducted a 5-year retrospective study of 111 snake bite patients who visited the emergency departments of several medical centers between January 2004 and December 2008. We categorized the patients into those who had complications with inadequate first aid, those who had complications without first aid and those who had complications with adequate first aid. We compared the general characteristics and the laboratory and clinical findings of the three groups. RESULTS: The male to female ratio was 1.36. The most common bite site was fingers. The most common systemic symptom was dizziness (6.3%) and the most common complication was rhabdomyolysis (23.4%). The inadequate first aids group had more local complications (cellulitis, skin necrosis) than did the group with adequate first aid or the group with no first aids. CONCLUSION: Inadequate first aid after snake bite leads to local complications, so we must be careful to administer first aid after snake bite and evaluate this first aid in relation to local complications

Various hematologic and vascular complications from snakebites have been reported in the literature. Spontaneous bleeding causing hematoma, however, is not a common complication of snakebites. Here we report a case of spontaneous retroperitoneal hematoma in which a 72-year-old male visited the emergency department with sudden-onset left flank pain and dizziness. Computed tomography (CT) revealed high-attenuation fluid collection in the retroperitoneum and contrast extravasation. Conservative treatment was continued and he was discharged without any complications after 7 days.

The clinical presentation of snake bites varies greatly. Symptoms range from only bite marks to muscle spasms, paralysis, altered mental status, and muscle weakness. In severe cases, symptoms may include life threatening coagulopathy or gastrointestinal bleeding owing to increased vascular permeability. In this report, the patient presented with massive gastrointestinal bleeding after a snake bite and recovered with conservative treatment.

PURPOSE: To describe the therapeutic effect of anticholinesterase treatment for patients with paralytic strabismus and blepharoptosis following a viper bite METHODS: A prospective non-comparative interventional case series study was designed including 6 patients with ophthalmic complications such as paralytic strabismus and blepharoptosis following a viper bite. Anticholinesterase (pyridostigmine) 60 mg was administered to patients 3 times a day in additional to conservative treatment including antivenom, antibiotics and tetanus toxoid. Patients underwent a measurement of deviation, diplopia test and MRD 1. Subjective evaluation of the diplopia symptoms was performed daily after treatment. RESULTS: Subjective diplopia was relieved in 2 out of the 6 patients on the first day and in the other 4 patients on the second day. The angle of deviation decreased approximately 37% on the first day and ocular position became orthophoric on the third day in all patients. The blepharoptosis was completely resolved in 4 patients on the first day. No complication following anticholinesterase treatment was noticed. CONCLUSIONS: Treatment using anticholinesterase for patients suffering from diplopia and blepharoptosis following a viper bite is an effective and safe treatment.
