Optimising the surgical outcome in a case of post-traumatic cataract using ultrasound biomicroscopy

A 12-year-old boy was brought with the chief complaint of diminution of vision in his left eye for the past 1 month. History revealed a blunt trauma to his left eye with a wooden stick 6âweeks ago.Visual acuity was 20/20 and hand movement close to face in right and left eye, respectively, without any relative afferent pupillarydefect. Slit-lamp examination showed a total cataractous lens with signs suggestive of suspected posterior capsular (PC) defect. The PC defect was screened initially using B-scan ultrasound of the posterior segment, followed by confirmation of the same using ultrasound biomicroscopy. Left eye lens aspiration along with limited anterior vitrectomy followed by placement of multipiece intraocular lens in the sulcus was performed. Best-corrected visual acuity at 6 months of follow-up was 20/20.

Giant oesophageal gastrointestinal stromal tumour presenting with dyspnoea and clubbed fingers

Gastrointestinal stromal tumours (GISTs) are mesenchymal neoplasms of the gastrointestinal tract originating from the interstitial cells of Cajal. Giant oesophageal GISTs are rare since the oesophagus is rarely the primary site of GISTs, and they are usually diagnosed early due to complaints such as dysphagia. We present the case of a giant oesophageal GIST presenting with prominent clubbing. The case underlined the diagnostic importance of clubbing and the careful consideration of chemotherapy. Although clubbed fingers associated with GISTs are rare, our experience demonstrates the importance of physicians' recognition of clubbing as a paraneoplastic phenomenon for early diagnosis of malignancies since patients seldom notice their own clubbing by themselves. Chemotherapy using imatinib, an Bcr-Abl kinase inhibitor, is the standard option for unresectable giant GISTs. However, careful consideration must be made of the risk of complications associated with rapid mass reduction due to imatinib such as bleeding, oesophageal perforation and mediastinitis.

Type I talon cusp on mandibular incisor

Description

Talon cusp is a comparably rare developmental dental anomaly assumed to arise because of evagination on the surface of a tooth crown during tooth calcification stage. Talon cusp also called as Eagle's is a well-defined extra cusp like structure located on lingual or palatal surface of deciduous or permanent anterior teeth. Its occurrence may be either unilateral or bilateral, single or multiple teeth in males or females. Prevalence of talon's cusp is reported to be between 0.06% to 7.7%. Eagle's talon is most commonly seen in maxillary lateral incisor >maxillary central incisor> maxillary canine> mandibular incisor.1

Mandibular talon cusp is a rare entity to occur. Mandibular talon cusps are more prevalent in men than women. Occurrence in talon cusp is more common in permanent dentition. Most of the mandibular talon cusp shows unilateral presentation. Talon cusp associated with permanent central incisor and primary lateral incisor...

Between fire and ice: refractory hypothermia and warmth-induced pain in inherited erythromelalgia

Inherited erythromelalgia (IEM) is a well-described pain disorder caused by mutations of sodium channel Na_v1.7, a peripheral channel expressed within dorsal root ganglion and the sympathetic ganglion neurons. Clinically, IEM is characterised by paroxysmal attacks of severe pain, usually in the distal extremities, triggered by warmth or exercise. Pain is not adequately treated by existing pharmacological agents. Individuals with IEM classically cool their limbs for relief, in some cases resulting in tissue injury. We describe a patient from a family with IEM due to the L858F mutation of Na_v1.7 who presented with refractory hypothermia due to overcooling. This presentation of refractory hypothermia necessitating warming strategies, complicated by severe warmth-induced pain, posed a substantial therapeutic challenge. We report our experience in overcoming hypothermia lasting 3 weeks in a child with IEM, discuss possible pathophysiological mechanisms underlying this unusual complication and suggest potential therapeutic interventions.

It Takes Two: One Resects, One Reconstructs

Care of patients with advanced head and neck cancer is a multidisciplinary effort through all phases of care. Head and neck cancer surgery involves balancing oncologic control, functional preservation, and aesthetics. Given the advances in free tissue reconstruction, the majority of defects can be reconstructed using free tissue transfer flaps. A 2-team approach allows for early, continual communication and meticulous operative planning. Operations can be combined into a single effort. This approach maximizes efficiency and enables multidisciplinary collaboration for comprehensive surgical treatment. We present our experience and an outline of how responsibilities between the ablative and reconstructive teams are shared.

Multidisciplinary Approach to Head and Neck Cancer

The complexity of cancer care in the twenty-first century mandates the input of a spectrum of health care providers to achieve the best possible outcome. Head and neck cancer in particular occurs in an anatomical region unmatched in the number of physiological functions potentially affected with disease and treatment, including respiration, physical appearance, vocalization, gustation, olfaction, and alimentation. Further complicating treatment is the wide range of tumor types and tumor locations in head and neck cancer, all of which taken separately are relatively rare cancers.
