Salivary Gland Stone (Sialolithiasis)

A salivary gland stone is a calcified mass of minerals or sialolith that is formed in the duct within the salivary gland. There are three pairs of major salivary glands, parotid, sublingual and submandibular. Similar to kidney stones and gallstones, one can also get a salivary gland stone. When this happens, it blocks the duct of one of the three salivary glands of the mouth. The cause is often unknown. Pain often improves when the stone is removed. Often, consuming concentrated citric juices such as lime juice will force the stone to come out. The gland may become infected if not treated.

Scalp Laceration

A cut on your scalp is also called a scalp laceration. These type of lacerations can bleed a lot and can often appear worrisome. However, the majority of these stop bleeding on their own.

To stop the bleeding, apply pressure to the wound by pressing a cloth or paper tissue forcibly. Keep applying pressure for 10 minutes without stopping.

Schizophrenia (Psychiatric Disease)

Mental disorder in which people interpret reality abnormally. Although a cause is not yet known, imaging studies point to differences in the structure of the brain and the central nervous system of people with this chronic condition. Although a cause has not been determined, the latest research points towards a combination of genetics, brain chemistry and environment contributes to development of the disorder. This mental disorder requires lifelong treatment and symptoms may appear between early and late 20’s. The symptoms displayed are different in teenagers and adults. Teenager’s symptoms are harder to diagnose since they are similar to the typical development of teenagers. Untreated, the disease can cause severe emotional, behavioral, health, and legal and financial problems. Lifelong treatment is needed, and can enable patients to live normal productive lives. This is a serious mental disorder with about 10% of patients committing suicide.

Sciatica (Lower Back Nerve Irritation)

Sciatica is a very common condition that causes back pain. The pain usually is in the lower back/hip area and shoots down the back of the thigh into the leg. The pain usually increases with flexion at the hip. Patients also experience numbness and occasionally weakness in the leg. The disorder was initially thought to be cause by irritation of the sciatic nerve, but now is felt to be secondary to a herniated lumbar disk compressing a nerve root, most commonly the L5 or S1 root. Although mild sciatica usually goes away over time if the pain continues it is important to see a doctor.
