particularly affects immunocompromised individuals, leading to secondary
bacterial and fungal infections. Mucormycosis, caused by Mucorales fungi, is
a severe infection primarily affecting immunocompromised individuals. The
COVID-19 pandemic has seen a surge in mucormycosis cases worldwide,
with India experiencing a significant increase. Various factors, including
diabetes mellitus, contribute to the risk of mucormycosis. This study
investigated head and neck mucormycosis in patients with prior COVID-19
infection.
Methods: Data from 45 patients were analyzed, with diabetes being the
most common risk factor. Visual symptoms, ethmoid bone involvement, and
orbital bone involvement were also identified as significant factors.
Results: The COVID-19 pandemic has led to an increase in mucormycosis
cases, particularly in the head and neck region, with high mortality. Successful
management involves addressing underlying factors, surgical debridement,
and antifungal therapy.
Conclusion: Timely debridement reduces morbidity and mortality.

Microscopic studies on angiolipoma show that it includes the mature lipocytes and blood vessels. Infiltrating angiolipoma is an un-capsulated angiolipoma and, due to penetration into the surrounding structures, complete excision of the tumor is difficult. According to previous studies, the relapse rate of the infiltrating angiolipoma after surgical intervention is 35-50%. Infiltrating angiolipoma is rarely seen in the head and neck region and often occurs in the trunk and limbs. In this study, we report a 10-year-old boy with periauricular infiltrating angiolipoma who underwent surgery. After surgery, the patient developed transient left frontal branch palsy, but recovery was excellent and after one year there is no relapse.

In this paper, we present a very rare case of asymptomatic intrusion of the mandibular condyle into the middle cranial fossa after orthognathic surgery in a 23 year old man from Iran.

Various types of adjuvant therapies, including intralesional corticosteroid injection are advocated to lower recurrence following excision. We investigated the efficacy of a protocol combined of excision and postoperative intralesional triamcinolone acetonide (TA) injection for treating earlobe keloids in a group of Iranian female patients. METHODS A retrospective analysis of 21 patients representing 31 ear keloids treated by a single physician between 2013 and 2017 was conducted. All keloids occurred after ear piercing in female cases. Postoperative intralesional TA injection was administered once monthly and continued for several months based on the patients’ clinical progress. Results were assessed according to Kyoto scar scale. RESULTS The patients’ mean age was 24.29 years and ranged from 16 to 40 years. After the surgery, the follow-up period ranged f...

Demographic information as well as etiology and pattern of ankylosis, the time lapse between injury and treatment, concomitant facial injury, fragment displacement, prior condyle treatment, mouth opening before and after treatment of ankylosis, complications, and position of the ramus stump or hemicondyle in relation to the glenoid fossa, follow up period, and physiotherapy before and after ankylosis treatment. Results: Among 32 patients with 45 involved joints, with an average age of 29.90± 17.08 years, mostly between 20-29 years old (n=10); the leading cause of tem...

This study aimed to compare the pooled event rate of pediatric perforated appendicitis before and during the COVID-19 pandemic. Methods: This was a systematic review and meta-analysis study based on the PRISMA guidelines. Scopus, Web of Sciences, and PubMed databases were searched for studies reporting the rate of perforated appendicitis based on the post-appendectomy observations or imaging methods. The Egger bias test and funnel plot were used to detect and depict publication bias. Statistical analysis was performed in Comprehensive Meta-analysis package version 3. Results: Twelve studies were eligible for inclusion in our study. The pooled prevalence of pediatric perforated appendicitis in the pre-COVID era was 28.5% (CI95%: 28.3 to 28.7%) with a heterogeneity of 99%. In the COVID era, the event rate proportion...

These injuries are rare and pose a difficult challenge for both ophthalmologist and plastic surgeon. Here we report an unusual case of pure periorbital electrical injury in a 12-yr old boy while drinking water from water dispenser.

Flattened endothelial cells line the vascular spaces, which were filled with blood. Though hemangiomas are the mast common benign neoplasms seen in children, they rarely occur in adults. In the head and neck region, the masseter and trapezius muscles are most commonly involved. Herein, the case is a 64 years old male who presented with a round, painless mass in the right temporal fossa with extension to infratemporal fossa. The lesion was surgically excised and histopathology confirmed the diagnosis of cavernous hemangioma.

The diagnosis was made by CT angiography. The patient suffered two episodes of mandibular fracture 3 months and 12 months ago. He was found to have a large AV fistula in left side of his neck. So the patient was scheduled for operation to correct fistula.

Instillation of hypertonic glucose into gall bladder of rabbit: Does it induce sclerosing cholangitis? J. Appl. Anim. Res, 29: 73–76.To study the effect of hypertonic glucose in induction of sclerosing cholangitis, glucose 10%, 15%, 25% and 50% were injected transhepatically into the gall bladder of 4 equal groups of 12 Dutch rabbits. Normal saline was similarly injected as group 5 (control group). Porta-hepatis was clamped for 5 minutes. Macroscopically and microscopically, the livers were normal without any bile stasis, fibrosis or nodular formation after 5 months of glucose injection. There was no sign of sclerosing cholangitis or cirrhosis. It is concluded that hypertonic glucose developed no sclerosing cholangitis or hepatic damage and is a safe scolicidal agent.

Many complications after septoplasty have been reported. Palatal perforation is one of the rarest complications with only a few cases reported in the literature. The reported cases had misdiagnosed submucousal cleft palate or high arched palate, but a patient with palatal perforation after septoplasty is presented here which have had neither evidence of submucousal cleft palate nor high arched palate.
