Small cell lung cancer, which occurs almost exclusively in smokers, is a malignancy characterised by rapid doubling time, high growth fraction and widespread metastasis at presentation. In this presentation, we will briefly discuss the classification of pulmonary Neuro-endocrine tumours by the World Health Organisation followed by a detailed discussion of the clinical features, lab evaluation and management of SCLC, both limited and extended stage. The frontline therapy in small cell lung cancer is etoposide and cisplatin along with thoracic radiotherapy and prophylactic cranial irradiation in patients who have a good response to therapy. Hyperfractionation of radiotherapy may provide some benefit but is also associated with increase incidence of complications. Newer agents for SCLC include Vandetanib and immunotherapy molecules, such as Iplimumab and nivolumab.
Hemophagocytic lymphohistiocytosis is a rare but life threatening condition characterised by activation of macrophages which result in phagocytosis of RBCs and cytokine mediated tissue damage. This presentation aims to discuss the genetic basis, clinical features, diagnostic criteria and management options in this serious condition.

A step wise approach to the pathogenesis, types, disease entities and diagnosis of vasculitis. This discussion also includes the management options of vasculitis and their adverse drug reactions. In essence, vasculitis is a clfinicopathologic process characterised by inflammation and damage of blood vessels. This may be mainly due to three pathological processes which include immune complex deposition, anti-neutrophillic antibody formation and pathological T lymphocyte response and granuloma formation. The disease entities include Wegner's granulomatosis, Churg Strauss and many others. These present with palpable purpura, unexplained renal dysfunction etc which can be diagnosed based on biopsy and angiogram.

Corneal cross-linking (CXL) is an in-office eye procedure that strengthens the cornea if it's been weakened by keratoconus, other corneal disease, or (rarely) a complication of LASIK surgery. Alternative and brand names for the procedure include corneal cross-linking, corneal collagen cross-linking, C3-R, CCL and KXL.
Acne can form several types of skin blemish, each with a distinct appearance and symptoms. Most minor acne blemishes respond to at-home care and over-the-counter medications. However, people with severe or long-term acne should speak with a doctor or dermatologist. Acne affects around 80 percent of adolescents and young adults.

They are solid, tender, pink, and raised, and the skin around a papule is usually slightly swollen and red. Unlike whiteheads, papules have no visible center. Unlike blackheads, the pores of a papule do not appear to be widened. Papules develop when whiteheads or blackheads cause so much irritation that they damage some of the surrounding skin. The damage leads to inflammation. Pustules (pimples) Pustules are larger, tender bumps with a defined circular center. The center is filled with whitish or yellowish pus, and the bump has a pink or red base. Immune cells and bacterial cells collect to form this pus. Pustules typically look like much larger and more inflamed whiteheads. Treatment options Several home remedies and over-the-counter medications can treat minor-to-mild papules and pustules.

Normally, dead cells collect in the skin's pores, then slowly rise to the surface of the openings and eventually fall away from the skin. A natural body oil called sebum helps to prevent skin cells from drying out. The glands that produce this oil are attached to the pores. When excess sebum builds up, it can cause dead cells to stick together, forming a mixture that becomes trapped in the pores. Acne occurs when a pore becomes clogged with dead skin cells, natural body oils, and a type of bacteria. These bacteria live on the skin and are called Propionibacterium acnes. If they enter and infect clogged pores, this causes acne blemishes to form. When to see a doctor In cases of minor-to-moderate acne, a person will generally have to use home and over-the-counter remedies consistently for 4–8 weeks before they see results. More severe inflammatory types of acne tend to take much longer to clear up.

Rubber band ligation is a procedure in which the hemorrhoid is tied off at its base with rubber bands, cutting off the blood flow to the hemorrhoid. This treatment is only for internal hemorrhoids. To do this procedure, a doctor inserts a viewing instrument (anoscope) into the anus. The hemorrhoid is grasped with an instrument, and a device places a rubber band around the base of the hemorrhoid. The hemorrhoid then shrinks and dies and, in about a week, falls off. A scar will form in place of the hemorrhoid, holding nearby veins so they don't bulge into the anal canal. The procedure is done in a doctor's office. You will be asked whether the rubber bands feel too tight. If the bands are extremely painful, a medicine may be injected into the banded hemorrhoids to numb them. After the procedure, you may feel pain and have a sensation of fullness in the lower abdomen. Or you may feel as if you need to have a bowel movement. Treatment is limited to 1 to 2 hemorrhoids at a time if done in the doctor's office. Several hemorrhoids may be treated at one time if the person has general anesthesia. Additional areas may be treated at 4- to 6-week intervals.
