Initial Report on Increasing Incidence of Diarrhea Cases in Barangay Culamdanum, Bataraza On March 31, 2011, the Provincial Health Office received a report from Dr.Mabutas, Municipal Health Officer of the Municipality of Bataraza, concerning deathsdue to diarrhea. Dr. Juan Mabutas asked for supply of ORS, IV fluid and antibioticswhich was immediately prepared and given to Ms. Emmy Asgali, nurse of Bataraza,who was in Puerto Princesa attending the FHSIS Data Validation. On April 3, 2011, an investigating team composed of Dr. Louie Ocampo, Ms.Lorna Loor (Surveillance Officer), Mr. Arnold Flores (Sanitary Inspector) and Ms.Jemadeth Cervancia (CHD Surveillance Officer) travelled to Bataraza to assist the RuralHealth Unit staff. Together with the RHU staff, the team went to Barangay Culandanumwhere cases came from. The team arrived in Culandanum at 2 PM. A young adult malewas seen with moderate signs of dehydration, and was treated accordingly. TheBarangay Captain and the midwife assigned in the area were interviewed. Theyreported that the most affected area was Apad-apad which is four hours (on foot) awayfrom the barangay health station of Culandanum. Since it was already past two PM, theBarangay Captain suggested delaying the hike in the mountain of Apad-apad until thenext day for security reasons. On April 4, 2011, the Sanitary Inspectors of PHO and MHO, a MedicalTechnologist, and some residents of Barangay Culandanum headed by the BarangayCaptain hiked going to Apad-apad to collect water sample and check on the status ofthe village where deaths were reported. With the help from Riotuba Nickel Mining (RTN) group headed by Dr. Mia, acamp was set-up in a school at Sitio Linao which is nearest to Apad-apad which wouldserve as half-way treatment center. Initially, a 45-year-old male came in with severedehydration. IV fluids were immediately started. Then, another one female adult, and atwo-year-old male came in with signs of moderate dehydration, and they were managedaccordingly. One male infant with mild signs of dehydration was also seen and givenORS treatment. Upon arrival of the group who went to Apad-apad, they have broughtwith them another two patients (one elderly female and a 12-year-old male). Both ofthem showed signs of severe dehydration, and fluid resuscitation was immediatelyinitiated. A male adult who survived the outbreak was also brought down by the group toshed light on the events that happened to his family and tribe. At the end of the day, all(5) patients were transferred to RTN Hospital for further evaluation and management.

Observations and Initial Findings: 1. The diarrhea outbreak is located in Barangay Culandanum mainly affecting the village of indigenous people in Apad-apad. 2. Affected individuals are member of the Palaw-an indigenous people. 3. Patients manifested symptoms of profuse watery diarrhea, abdominal pain and vomiting. 4. Fast progression of symptoms and rapid deterioration of patient’s condition from the onset of initial symptoms to severe dehydration and sudden death. 5. Affected individuals sourced drinking water from a shallow-dug well beside a stream. 6. A high suspicion of cholera and a contaminated water source 7. None of the affected individuals consulted a health provider and given any form of treatment prior to demise. 8. None of the deaths was seen by a health provider. 9. Seven cases of diarrhea with varying degree of dehydration were seen during the investigation (April 3-4, 2011). Six of them came from Apad-apad , and one from Bato which is another sitio of Culandanum. 10. Fifteen deaths were reported and verified by the member of the tribe who survived the outbreak. 11. Eleven out of 15 deaths (73%) are children less than 5 years old.Name of Patients who Died on March 27, 2011 Sex/Age 1. Armina Gangan 24/F 2. Joselina Gangan 1/F 3. Esrade Enyong 4/M 4.

Actions Taken: 1. Coordination with involved agencies and the community. 2. Barangay assembly with local officials, RHU staff, and RTN group was conducted. 3. Planning of activities and spot mapping were carried out. 4. Focused and culturally-appropriate information and education campaign was initiated 5. Seven patients with varying degree of dehydration were seen and managed accordingly. Five were transferred to RTN Hospital and two were sent home after observation. 6. Water sample taken from the identified water source 7. Rectal swab and stool specimens were taken from patients for confirmation of suspected cholera outbreak. 8. Water chlorination was instructed and demonstrated to the indigenous people 9. ORS, IV fluids, Hyposol, Aquatabs and antibiotics given to affected individuals 10. Mortality was verified and counter-checked from different sources 11. Barangay Captains forewarned of possible spread of infection particularly to communities being supplied by the identified stream/river 12. RHU was advised to station a vaccinating team at least every month at Sitio Linao which is more accessible to indigenous people than the health center in Culadanum.Plans: 1. The “survivor” together with local residents will go to the cave where the other members of the tribe are now staying. He will persuade the affected ones to come down at the treatment camp for proper care. 2. Continuous education of the captured patients. 3. The treatment camp will stay operational and serve these patients for another 1-2 days or until the outbreak is deemed controlled. 4. The PHO and CHD staff (Lorna, Arnold, Jemadeth) together with Dr. Mabutas and RTN group will stay at the treatment camp until the outbreak is declared controlled.Recommendations: 1. Provision of safe water supply specifically for the indigenous people. A stream was identified and suggested by the Barangay Captain as a possible source of water. A system of pipes is to be installed to supply communities down the stream.

2. Institutionalize a health education program which is culturally-sensitive and appropriate focusing on the indigenous people. 3. Encourage members of the indigenous people to engage in health activities of RHU such as inviting them to be involved as BHW or BNS. 4. Proactive response of RHU in possible outbreaks particularly in the rainy seasons. Heightening level of alert of all health personnel for rising cases of diarrhea during rainy seasons to institute timely and appropriate response. 5. “Adopt-a-community” program to be implemented in areas where indigenous people reside. This is to ascertain that an “adopter” RHU health personnel ensures implementation of health programs in this community and monitoring of diseases and possible outbreaks. The “adopter” will also serves a direct linkage of the indigenous community to the RHU and other involved agencies.Prepared by:Louie R.

HEALTH EFFECTS OF NICKEL by y Rebecca Green F.I.M.F. Consultant to the Nickel Institute

FORMS TO BE CONSIDERED• Ni metal dusts – usually insoluble• Partially soluble Ni salts y nickel oxides, sulphides, carbonate• Soluble Ni salts nickel sulphate, nickel chlorideThis presentation will mainly consider the health effects of soluble nickel salts.

MOBILITY & EXCRETION• Ni metal dusts • Little transport away from absorption site • Excreted via faeces. May stay in body for years• NiO, NiS • Some transport away from absorption site • Excreted via kidney & faeces. ½ life in body 200 days b d ~200 d• NiSO4, NiCl2 • Transported around body to all organs • Excreted via kidney after ~28hrs. May stay in lungs for years

ACUTE & CHRONIC EXPOSURE• Acute exposure usually • One-off • Relatively high dose• Chronic exposure usually • Over a long period of time – months or y years • Relatively small dose, (though not necessarily)

ROUTES OF EXPOSURE• Inhalation – breathing in dust, fume & mists g• Ingestion ( g (oral) – by mouth ) y• Dermal (skin/eyes) – skin or clothing contamination

EFFECTS OF ACUTE Ni INHALATION– death (Ni dust) after 90 min exposure 1 reported case p– asthma (fumes), an electroplater who later ( ), p developed Ni dermatitis

EFFECTS OF CHRONIC Ni INHALATION• Increased risk of cancer in – lung, specially soluble species, >1mg/m3 – nasal, dust & partially soluble species – stomach, 1 study of UK electroplaters• Non-malignant lung damage (like “miner’s lung”)• Asthma• Rhinitis & sinusitis• Damage to septum of nose• Loss of or reduced sense of smell

EFFECTS OF Ni INGESTION• Acute – Death, 2 yr old ingested 570mg Ni/Kg BW – Nausea vomiting giddiness lassitude Nausea, vomiting, giddiness, lassitude, palpitations, headache, cough. Recovery within 8 days. y• Chronic – may provoke dermatitis in sensitised individuals (e.g. diet high in Ni) – no others reported in humans p

EFFECTS OF SKIN EXPOSURE TO NICKEL• Acute – Eyes: conjunctivitis, floods of tears – Skin: contact dermatitis. To develop, skin must first be sensitised by contact Any develop contact. subsequent contact then results in dermatitis.• Chronic – Eyes: none reported in humans – Skin: contact dermatitis Little reported evidence of transport through system for Ni absorbed through skin.

OTHER HEALTH EFFECTS OF Ni ABSORPTION• Immune System – May over stimulate immune system• Nervous System – Symptoms reported in acute exposures• G Genetic Effects ti Eff t – Some evidence of genetic damage• Reproduction, Embryotoxicity, Teratogenicity – No reliable human data available

IN SUMMARYMain effects of acute Ni absorption through:Inhalation – death (1case) – asthma, irritation of upper respiratory tract th i it ti f i t t tSkin & Eyes – conjunctivitis running eyes conjunctivitis, – dermatitisIngestion g – death (1case) – vomiting, giddiness, palpitations, lassitude, cough

IN SUMMARYMain effects of chronic Ni absorption• Exposure by Inhalation Risk significantly increased at levels >1mg/m3 (soluble) & 10mg/m3 (less/insoluble) – increased risk of cancers – long term damage to the respiratory tract – asthma

IN SUMMARYMain effects of chronic Ni absorption p• Exposure by Ingestion – no long term effects reported• Exposure through the Skin & Eyes – Dermatitis (Ni itch) – NiCl2 is more potent sensitiser than NiSO4
